C II Abundances in Early-Type Stars: Solution to a Notorious Non-LTE Problem
We address a long-standing discrepancy between non-LTE analyses of theprominent C II 4267 and 6578/82 Å multiplets in early-type stars.A comprehensive non-LTE model atom of C II is constructed based oncritically selected atomic data. This model atom is used for anabundance study of six apparently slow-rotating main-sequence and giantearly B-type stars. High-resolution and high S/N spectra allow us toderive highly consistent abundances not only from the classical featuresbut also from up to 18 additional C II lines in the visual-including twoso far unreported emission features equally well reproduced in non-LTE.These results require the stellar atmospheric parameters to bedetermined with care. A homogeneous (slightly) subsolar present-daycarbon abundance from young stars in the solar vicinity (in associationsand in the field) of log(C/H)+12=8.29+/-0.03 is indicated.
A high-resolution spectroscopy survey of β Cephei pulsations in bright stars
We present a study of absorption line-profile variations in early-B typenear-main-sequence stars without emission lines. We have surveyed atotal of 171 bright stars using the Nordic Optical Telescope (NOTSA),William Herschel Telescope (ING) and Coudé Auxiliary Telescope(ESO). Our sample contains 75% of all O9.5-B2.5 III-V non-emission-linestars brighter than 5.5 mag. We obtained high signal-to-noise,high-resolution spectra of the SiIII λ4560 triplet - for 125stars of our sample we obtained more than one spectrum - and examinedthese for pulsational-like line-profile variations and/or structure. Weconclude that about half of our sample stars show evidence forline-profile variations (LPV). We find evidence for LPV in about 65% ofour sample stars brighter than V=5.5. For stars with rotationalbroadening V sin i 100 km s-1, we find evidence for LPVin about 75% of the cases. We argue that it is likely that these LPV areof pulsational origin, and that hence more than half of thesolar-neighbourhood O9.5-B2.5 III-V stars is pulsating in modes that canbe detected with high-resolution spectroscopy. We detected LPV in 64stars previously unknown to be pulsators, and label these stars as newβ Cep candidates. We conclude that there is no obvious differencein incidence of (pulsational) LPV for early-B type near-main-sequencestars in binaries or in OB associations, with respect to single fieldstars.
Catalog of Galactic β Cephei Stars
We present an extensive and up-to-date catalog of Galactic β Cepheistars. This catalog is intended to give a comprehensive overview ofobservational characteristics of all known β Cephei stars, coveringinformation until 2004 June. Ninety-three stars could be confirmed to beβ Cephei stars. We use data from more than 250 papers publishedover the last nearly 100 years, and we provide over 45 notes onindividual stars. For some stars we reanalyzed published data orconducted our own analyses. Sixty-one stars were rejected from the finalβ Cephei list, and 77 stars are suspected to be β Cepheistars. A list of critically selected pulsation frequencies for confirmedβ Cephei stars is also presented.We analyze the β Cephei stars as a group, such as the distributionsof their spectral types, projected rotational velocities, radialvelocities, pulsation periods, and Galactic coordinates. We confirm thatthe majority of the β Cephei stars are multiperiodic pulsators. Weshow that, besides two exceptions, the β Cephei stars with highpulsation amplitudes are slow rotators. Those higher amplitude starshave angular rotational velocities in the same range as thehigh-amplitude δ Scuti stars (Prot>~3 days).We construct a theoretical HR diagram that suggests that almost all 93β Cephei stars are main-sequence objects. We discuss theobservational boundaries of β Cephei pulsation and the physicalparameters of the stars. We corroborate that the excited pulsation modesare near to the radial fundamental mode in frequency and we show thatthe mass distribution of the stars peaks at 12 Msolar. Wepoint out that the theoretical instability strip of the β Cepheistars is filled neither at the cool nor at the hot end and attempt toexplain this observation.
Video observation of meteors at Yunnan Observatory
In the last 20 years, with the development of the CCD and imageintensifiers, the use of small flexible video meteor observation systemshas gradually increased, with the prospect that one day videoobservation will replace the visual observation and ordinaryphotographic observations. In this paper we report on the research anddevelopment of the No.1 meteor-comet video camera system of YunnanObservatory and some preliminary observed results. The system consistsof 5 changeable modules; it has a 36° large-field camera dedicatedto the observation of meteors, with which a magnitude 6 star can berecorded on a single frame with an accuracy of about 0.2 mag. We alsopresent a comparison of the video camera system with the traditionalphotographic system, and outline the merits, possible improvements andfuture development of the video system.
A 3-5 μ m VLT spectroscopic survey of embedded young low mass stars I. Structure of the CO ice
Medium resolution (lambda /Delta lambda = 5000-10 000) VLT-ISAACM-band spectra are presented of 39 young stellar objects in nearbylow-mass star forming clouds showing the 4.67 μm stretching vibrationmode of solid CO. By taking advantage of the unprecedentedly largesample, high S/N ratio and high spectral resolution, similarities in theice profiles from source to source are identified. It is found thatexcellent fits to all the spectra can be obtained using aphenomenological decomposition of the CO stretching vibration profile at4.67 μm into 3 components, centered on 2143.7 cm-1, 2139.9cm-1 and 2136.5 cm-1 with fixed widths of 3.0, 3.5and 10.6 cm-1, respectively. All observed interstellar COprofiles can thus be uniquely described by a model depending on only 3linear fit parameters, indicating that a maximum of 3 specific molecularenvironments of solid CO exist under astrophysical conditions. A simplephysical model of the CO ice is presented, which shows that the 2139.9cm-1 component is indistinguishable from pure CO ice. It isconcluded, that in the majority of the observed lines of sight, 60-90%of the CO is in a nearly pure form. In the same model the 2143.7cm-1 component can possibly be explained by the longitudinaloptical (LO) component of the vibrational transition in pure crystallineCO ice which appears when the background source is linearly polarised.The model therefore predicts the polarisation fraction at 4.67 μm,which can be confirmed by imaging polarimetry. The 2152 cm-1feature characteristic of CO on or in an unprocessed water matrix is notdetected toward any source and stringent upper limits are given. Whenthis is taken into account, the 2136.5 cm-1 component is notconsistent with the available water-rich laboratory mixtures and wesuggest that the carrier is not yet fully understood. A shallowabsorption band centered between 2165 cm-1 and 2180cm-1 is detected towards 30 sources. For low-mass stars, thisband is correlated with the CO component at 2136.5 cm-1,suggesting the presence of a carrier different from XCN at 2175cm-1. Furthermore the absorption band from solid13CO at 2092 cm-1 is detected towards IRS 51 inthe rho Ophiuchi cloud complex and an isotopic ratio of12CO/13CO=68+/-10 is derived. It is shown that allthe observed solid 12CO profiles, along with the solid13CO profile, are consistent with grains with an irregularlyshaped CO ice mantle simulated by a Continuous Distribution ofEllipsoids (CDE), but inconsistent with the commonly used models ofspherical grains in the Rayleigh limit.Based on observations obtained at the European Southern Observatory,Paranal, Chile, within the observing programs 164.I-0605 and 69.C-0441.ISO is an ESA project with instruments funded by ESA Member States(especially the PI countries: France, Germany, The Netherlands and theUK) and with the participation of ISAS and NASA.Table \ref{SourceList} and Appendices A and B are only available inelectronic form at http://www.edpsciences.org
Revisiting the solid HDO/H2O abundances
We revisit the reported detection and upper limits on HDO in ice mantlespresent in the molecular cloud environments of the massive youngprotostars Gl 2136 and W33 A, using independent VLT-ISAAC and UKIRT-CGS4spectroscopic observations. We also present VLT and UKIRT spectra ofRAFGL 7009 near the HDO absorption wavelength and reanalyze the ISO-SWSspectral data for NGC 7538 IRS9, Orion-BN and S140. We demonstrate thatthe previously reported detections of HDO in W33 A and NGC 7538 IRS9 areincorrect. We present an in-depth analysis that shows that, besides thesensitivity limits, detection of low levels of HDO is difficult inamorphous ice mantles when features from solid methanol, a common grainmantle constituent, are present. We discuss the specific problemsarising in the ISO data in this wavelength range for NGC 7538 IRS9.Using VLT-ISAAC observations, we also investigate the HDO/H2Oratio toward the intermediate mass stars IRAS 05329-0728 and IRAS08448-4343. Our derived upper limits for the D/H ratio in water icerange from HDO/H2O < 1% to 0.2% in the different sources,and we discuss these limits in comparison with values derived in otherenvironments.Based on observations collected at the European Southern Observatory,Paranal, Chile (ESO Programme 164.I-0605(A)), UKIRT, Mauna Kea, Hawaii,and ISO satellite.

Boron Abundances in Early B Stars: Results from the B III Resonance Line in IUE Data
We have used archival International Ultraviolet Explorer high-dispersionSWP spectra to study the B III resonance line at 2065.8 Å in 44early B stars. We find a median boron abundance about half that of solarsystem meteoritic material, consistent with the values found fromprevious studies of boron in early B stars. About one-third of the starsstudied appear to have boron abundances that are a factor of 4 or morelower than this median. Many of these are stars with enhanced nitrogenabundances, confirming the belief that deep envelope mixing can occur inmain-sequence B stars. A few stars with low boron abundances have normalN/C ratios. It is unclear whether all of these can be explained as starswhere mixing depleted the boron but did not go deep enough to bringCN-processed material to the surface or if some stars were actuallyformed with an unusually low boron abundance.
Observations of OB-stars at the former Leiden Southern Station
About 700 stars, mostly OB-stars, were observed by the author at theformer Leiden Southern Station at Hartebeespoortdam, South Africa, inthe observing seasons 1965, 1968, 1969, 1974, 1977, 1978. Observationswere made in the five channels of the Walraven photometric system. Dueto weathering of the telescope mirror the W channel gave no reliableresults for the faintest stars (m = 11 mag); in these cases the U-Wcolour index is not given. The change in sensitivity in the V channel,supposedly having occurred in 1968, was not recognised.

The proper motions of fundamental stars. I. 1535 stars from the Basic FK5
A direct combination of the positions given in the HIPPARCOS cataloguewith astrometric ground-based catalogues having epochs later than 1939allows us to obtain new proper motions for the 1535 stars of the BasicFK5. The results are presented as the catalogue Proper Motions ofFundamental Stars (PMFS), Part I. The median precision of the propermotions is 0.5 mas/year for mu alpha cos delta and 0.7mas/year for mu delta . The non-linear motions of thephotocentres of a few hundred astrometric binaries are separated intotheir linear and elliptic motions. Since the PMFS proper motions do notinclude the information given by the proper motions from othercatalogues (HIPPARCOS, FK5, FK6, etc.) this catalogue can be used as anindependent source of the proper motions of the fundamental stars.Catalogue (Table 3) is only available at the CDS via anonymous ftp tocdsarc.u-strasbg.fr (18.104.22.168) or viahttp://cdsweb.u-strastg.fr/cgi-bin/qcat?J/A+A/365/222
Sixth Catalogue of Fundamental Stars (FK6). Part I. Basic fundamental stars with direct solutions
The FK6 is a suitable combination of the results of the HIPPARCOSastrometry satellite with ground-based data, measured over more than twocenturies and summarized in the FK5. Part I of the FK6 (abbreviatedFK6(I)) contains 878 basic fundamental stars with direct solutions. Suchdirect solutions are appropriate for single stars or for objects whichcan be treated like single stars. From the 878 stars in Part I, we haveselected 340 objects as "astrometrically excellent stars", since theirinstantaneous proper motions and mean (time-averaged) ones do not differsignificantly. Hence most of the astrometrically excellent stars arewell-behaving "single-star candidates" with good astrometric data. Thesestars are most suited for high-precision astrometry. On the other hand,199 of the stars in Part I are Δμ binaries in the sense ofWielen et al. (1999). Many of them are newly discovered probablebinaries with no other hitherto known indication of binarity. The FK6gives, besides the classical "single-star mode" solutions (SI mode),other solutions which take into account the fact that hidden astrometricbinaries among "apparently single-stars" introduce sizable "cosmicerrors" into the quasi-instantaneously measured HIPPARCOS proper motionsand positions. The FK6 gives in addition to the SI mode the "long-termprediction (LTP) mode" and the "short-term prediction (STP) mode". TheseLTP and STP modes are on average the most precise solutions forapparently single stars, depending on the epoch difference with respectto the HIPPARCOS epoch of about 1991. The typical mean error of anFK6(I) proper motion in the single-star mode is 0.35 mas/year. This isabout a factor of two better than the typical HIPPARCOS errors for thesestars of 0.67 mas/year. In the long-term prediction mode, in whichcosmic errors are taken into account, the FK6(I) proper motions have atypical mean error of 0.50 mas/year, which is by a factor of more than 4better than the corresponding error for the HIPPARCOS values of 2.21mas/year (cosmic errors included).
A Second Catalog of Orbiting Astronomical Observatory 2 Filter Photometry: Ultraviolet Photometry of 614 Stars
Ultraviolet photometry from the Wisconsin Experiment Package on theOrbiting Astronomical Observatory 2 (OAO 2) is presented for 614 stars.Previously unpublished magnitudes from 12 filter bandpasses withwavelengths ranging from 1330 to 4250 Å have been placed on thewhite dwarf model atmosphere absolute flux scale. The fluxes wereconverted to magnitudes using V=0 for F(V)=3.46x10^-9 ergs cm^-2 s^-1Å^-1, or m_lambda=-2.5logF_lambda-21.15. This second catalogeffectively doubles the amount of OAO 2 photometry available in theliterature and includes many objects too bright to be observed withmodern space observatories.

Mapping the contours of the Local bubble: preliminary results
We present preliminary results from a long-term program of mapping theneutral absorption characteristics of the local interstellar medium,taking advantage of Hipparcos stellar distances. Equivalent widths ofthe NaI D-line doublet at 5890 Å are presented for thelines-of-sight towards some 143 new target stars lying within 300 pc ofthe Sun. Using these data which were obtained at the Observatoire deHaute Provence, together with previously published NaI absorptionmeasurements towards a further 313 nearby targets, we present absorptionmaps of the distribution of neutral gas in the local interstellar mediumas viewed from 3 different galactic projections. In particular, thesemaps reveal the Local Bubble region as a low neutral densityinterstellar cavity in the galactic plane with radii between 65-250 pcthat is surrounded by a (dense) neutral gas boundary (or ``wall''). Wehave compared our iso-column contours with the contours derived bySnowden et al. (\cite{snowden98}) using ROSAT soft X-ray emission data.Consistency in the global dimensions derived for both sets of contoursis found for the case of a million degree hot LB plasma of emissivity0.0023 cm(-6) pc with an electron density of 0.005 cm(-2) . We havedetected only one relatively dense accumulation of cold, neutral gaswithin 60 pc of the Sun that surrounds the star delta Cyg, and note thatthe nearest molecular cloud complex of MBM 12 probably resides at thevery edge of the Local Bubble at a distance of ~ 90 pc. Our observationsmay also explain the very different physical properties of the columnsof interstellar gas in the line-of-sight to the two hot stars epsilonCMa and beta CMa as being due to their locations with respect to theBubble contours. Finally, in the meridian plane the LB cavity is foundto be elongated perpendicularly to the Gould's Belt plane, possiblybeing ``squeezed'' by the expanding shells of the Sco-Cen andPerseus-Taurus OB associations.

The Tokyo PMC catalog 90-93: Catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo photoelectric meridian circle
The sixth annual catalog of the Tokyo Photoelectric Meridian Circle(PMC) is presented for 6649 stars which were observed at least two timesin January 1990 through March 1993. The mean positions of the starsobserved are given in the catalog at the corresponding mean epochs ofobservations of individual stars. The coordinates of the catalog arebased on the FK5 system, and referred to the equinox and equator ofJ2000.0. The mean local deviations of the observed positions from theFK5 catalog positions are constructed for the basic FK5 stars to comparewith those of the Tokyo PMC Catalog 89 and preliminary Hipparcos resultsof H30.
A Minisurvey of Interstellar Titanium from the Southern Hemisphere
We describe the results of a minisurvey of interstellar Ti II and Ca IIabsorption toward 42 early-type stars observed from the southernhemisphere at a spectral resolution of 4.5 km s-1. Results are alsopresented for the Na I ultraviolet line (3302 Angstroms) detected towardnine of these targets. We examine the dependence of the integratedcolumn densities of N(Ti II), N(Ca II), and N(Na I) on distance,reddening, neutral hydrogen column density, and their Galactic elementalabundance. Our findings support the proposition that Ti II and Ca IIabsorption originates in the same regions of the pervasive, warm, andneutral intercloud gas of the interstellar medium. We have observed acorrelation of decreasing Ti and Ca abundance with increasingline-of-sight gas density. The Ti II/Ca II abundance ratio has beenfound to be essentially constant under all the interstellar densityconditions we have sampled. Thus, we conclude that the generalabsorption properties of titanium (and calcium) are similar throughoutthe entire disk of our Galaxy.

Accuracy of effective temperatures of solar chemical composition stars derived from the flux fitting method.
We discuss the uncertainties affecting the determinations of effectivetemperature and apparent angular diameters based on the flux fittingmethod. We use Kurucz model fluxes and the spectrophotometric scansgiven in Breger Catalog. In particular, we analyze and discuss theinfluence of indetermination which may affect the fixed secondaryparameters (i.e. surface gravity, overall metallicity, and interstellarreddening correction) on the estimates of the fitted parameters, T_eff_and φ. The role of different sources of data for the same star andof each of the above mentioned parameters is described in detail forfive representative stars, while 130 non-supergiant solar chemicalcomposition stars, in the spectral range G8 - B0, are used toquantitatively illustrate the statistical behaviour of uncertainties.

The ROSAT all-sky survey catalogue of optically bright OB-type stars.
For the detailed statistical analysis of the X-ray emission of hot starswe selected all stars of spectral type O and B listed in the Yale BrightStar Catalogue and searched for them in the ROSAT All-Sky Survey. Inthis paper we describe the selection and preparation of the data andpresent a compilation of the derived X-ray data for a complete sample ofbright OB stars.
Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
The determination of T_eff_ of B, A and F main sequence stars from the continuum between 3200 A and 3600 A.
A method of determination of the effective temperature of B, A and Fmain sequence stars is proposed, using the slope of the continuumbetween 3200A and 3600A. The effective temperature calibration is basedon a sample of stars with energy distributions known from UV to the red.We have determined the Balmer jump and the effective temperatures for235 main sequence stars. The temperatures found have been compared withthose derived by Underhill et al. (1979), Kontizas & Theodossiou(1980), Theodossiou (1985), Morossi & Malagnini (1985). Thecomparison showed good agreement for most of the stars in common. On theother hand, the temperatures derived from the reddening-free colourfactor QUV, from the colour index (m1965-V) and from (B-V), given inGulati et al. (1989), are systematically lower than our temperatures,however the differences are within one-sigma error.

An atlas of ultraviolet P Cygni profiles
We have selected spectra of 232 stars from the International UltravioletExplorer (IUE) archives for inclusion in an atlas intended for varioususes but tailored especially for the study of stellar winds. The atlascovers the range in spectral types from O3 to F8. The full atlas coversthe reduced and normalized high resolution spectra from the IUE long-and short-wavelength spectrographs. Here we discuss the selection of thestars and the data reduction, and we present in velocity units theprofiles of lines formed in the stellar winds. The selected lines covera wide range of ionizations, allowing a comparison of the profiles fromdifferent ions in the wind of each star and a comparison of thedifferent wind lines as a function spectral type and luminosity. We alsopresent the basic data on the program stars to facilitate study of thedependence of wind features on stellar parameters such as luminosity,temperature, escape velocity, and v sin i. We provide an overview of thecharacteristic behavior of the wind lines in the H-R diagram. Thecomplete spectra are available in digital form through the NASAAstrophysics Data System (ADS). We offer a description of the electronicdatabase that is available through the ADS and guidelines for obtainingaccess to that database.
An IUE survey of interstellar H I LY alpha absorption. 1: Column densities
We measure Galactic interstellar neutral hydrogen column densities byanalyzing archival interstellar Ly alpha absorption line data toward 554B2 and hotter stars observed at high resolution with the IUE satellite.This study more than doubles the number of lines of sight with measuresof N(H I) based on Ly alpha. We have included the scattered lightbackground correction algorithm of Bianchi and Bohlin in our datareduction. We use the correlation between the Balmer discontinuity(c1) index and the stellar Ly alpha absorption in order toassess the effects of stellar Ly alpha contamination. Approximately 40%of the B stars with measured (c1) index, exhibit seriousstellar Ly alpha contamination. One table contains the derived values ofthe interstellar N(H I) for 393 stars with at most small amounts ofstellar contamination. Another lists the observed values of total N(H I)for 161 stars with suspected stellar Ly alpha contamination and/oruncertain stellar parameters.
Second astrolabe catalogue of Santiago.
Positions for 350 FK5 and 164 FK5 Extension stars as determined with theDanjon astrolabe of Santiago and differences astrolabe-catalogue aregiven for Equinox J2000.0 and for the mean observation epoch of eachstar. The average mean error in alpha is +/-0.005s and +/-0.07" indelta. The mean epoch of observation of the catalogue is J1979.96.

Donald Trump's declaration on Thursday that "if countries are going to have nukes, we're going to be at the top of the pack," flew in the face of decades of U.S. efforts to negotiate cautious, mutual reductions in nuclear arsenals around the world.
Trump's comments to Reuters essentially invited other nuclear powers to escalate their capabilities, and has the potential to set off a new nuclear arms race.
"Mr. Trump must be careful not to upend decades of successful efforts to reduce bloated nuclear arsenals," said Daryl Kimball, executive director of the Arms Control Association. "The five most recent U.S. presidents, including Barack Obama, George W. Bush, Bill Clinton, George H.W. Bush, and Ronald Reagan, all negotiated agreements with Russia to reduce their nuclear stockpiles."
The Nuclear Non-Proliferation Treaty, which Congress ratified in 1970, requires the U.S. to pursue the "cessation" of a nuclear arms race between superpowers, and to take steps towards mutual disarmament. The whole idea was to end the nuclear arms race forever.
Trump has stoked fears about a new arms race before. When pressed for details about his nuclear policies in December, he told MSNBC's Morning Joe "let it be an arms race," and later tweeted that the U.S. should "greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes."
Trump's spokespeople spent the following day trying to walk back his comments. But he later made his views on nuclear reduction clear when he told Russian President Vladimir Putin that he considers the Obama-era New START treaty a bad deal. The treaty calls for both countries to reduce their deployed strategic nuclear warheads to no more than 1,550, the lowest level in decades.
The Russians currently have slightly more nuclear warheads than the U.S. — but the U.S., by contrast, has more strategic warhead launchers, according to the latest figures.
"The U.S. has certainly not 'fallen behind' on nuclear weapon capability," wrote Hans Kristensen, a nuclear expert at the Federation of American Scientists, in an email to The Intercept. "It is already 'at the top of the pack' and has the most capable nuclear forces in the world backed up by overwhelming conventional forces."
In 2013, national security officials in President Obama's White House determined that the U.S. could safely reduce its deployed nuclear force by one-third. Other experts have said it could go much lower.
But instead of pursuing reductions that could have saved hundreds of billions of dollars, the Obama administration started investing in a trillion-dollar effort to modernize the arsenal, which budget critics slammed as unaffordable.
Excerpt from detailed posting about nuclear spend-up, from weapons experts' blog (link at bottom):
"A particularly dangerous component of the Obama nuclear spending plan is the acquisition of low-yield precision-guided nuclear bombs/warheads. These weapons only make sense within a radical strategy for actually fighting a nuclear war — as opposed to the almost universally accepted idea that our nuclear arsenal exists only to deter any thought of using these weapons — since actual use is unthinkable, with profoundly unknowable consequences."
Erm, did you kind of miss the last 70 years of American strategic military thinking?
I would say what planet are you living on but nased on what you omit you can only be a neocon shill .Obama os the one who budgeted the one trillion nuclear capability upgrade. Obama is the one that ratcheted up the Ukrainian offense and Nato military build-up right on Russia's doorstep. The current crazy talk against Russia is far more damaging to any reduction of nuclear arms and beings us closer to armagedon every day.
Please remember that Trump was elected on a platform of peace with Russia and no intervention in other states.
That things are mot quite working out that way are directly caused by the neocons endless war ideology.
I think this has something to do with the size of his hands. It's called compensating. Most guys with this issue buy a corvette but when you're the president and have a solid 2 inches flacid, then you just put all your energy into stockpiling. Either that or he's secretly a comic book bad guy.
Not sure why we're doing an article on the latest instance of the rabid dog foaming at the mouth. We all know full well that tomorrow he could completely contradict himself and voice some alternate but equally stupid remark. Why not just wait to see if he actually initiates some substantive proposal before giving airtime to what is likely just the latest instance of his taking a verbal dump in public?
Impeach President Bannon and remove the radical far right regime for good.
Lock em up! Lock em up!
My prediction is that after "Donald's First 100 Days" we surely can conclude that this president is suffering heavily from Borderline-syndrome.
Just ask yourselves: on a scale of 1 to 10 how much of a moron and a tosser is Donald ?
It's the Bozos who voted him in I am worried about: The IQ Bell Curve promoting one of their own.
I just sat 12 hours long haul next to two supporters who think he will be great because he is a whizz-bang businessman who will bring about change…
People want Change, not Revolution. Revolution is just too out there and interferes with Baby Boomers' retirement plans and leisure commitments.
This is the problem with Democracy: It is rule by selfish morons.
This could be a beautiful way of bankrupting usa_naziland, all other nations need to do is make out they are going for 10,000 nukes each. With this lunatic happily enforcing the psychotic military industrial complex into following suit. The losers would be the american public who already have nearly 46%+ of all taxes raised spent on death-culture stuff.
The intelligent leaders of the world will no longer be found in the US– if they ever were. The world does not have to partake of America, and more of it is not.
Remembering that America gave birth to the people that support Donald Trump and the destruction of the United States democracy.
Remembering that America gave birth to the people that elected Donald Trump and are just as much to blame for the destruction of the United States and it's democracy, should his time in office make this a reality.
I think it will be a very good idea to nuke a few Syrian cities like Racqa and Aleppo. Most of the good people are already here, and the no-so-good-ones are generally in Germany, France and many even freaking out in Sweden. Only the real-bad-ones are now left there along with ISIS. Nuking will not only finish ISIS, but will also demolish all the buildings that are extensively damaged, which would otherwise take years and billions of dollars to accomplish. This will also teach Putin not to meddle around with our elections.
I remember that just a few days before 9/11 one Afghan bloke was killed by terrorists pretending to be journalists from some Fake News agency. This time the apparently unnecessary murder of Kim Jong Nam by his lunatic step-brother indicates sufficient reasons for us to keep watch on that chap. Usually crazy, rogue dictators eliminate domestic enemies before launching attacks on foreign enemies. Which makes me wonder why we are not preemptively nuking Pyongyang.
"I think it will be a very good idea to nuke a few Syrian cities like Racqa and Aleppo"
Holy hell that is an incredibly stupid idea.
Trump is insane!
This article is a joke. Obama just fought for and received a trillion dollar nuclear weapons modernization budget. This budget will be spent over ten years:
"President Obama has authorized a nuclear modernization program that would cost $1 trillion."
The title of this piece is fiction. There is no 'new' nuclear arms race. Obama restarted it last year with the help of the Republican congress. Trump just wants to spend Obama's blank check.
"The United States is initiating a new nuclear arms race, because the other nuclear-armed states, of course, when they look at our 'modernization program,' are now beginning their own,"
– Marylia Kelley
Communities Against a Radioactive Environment
Moral of the story: Liberals don't care about nuclear weapons or nuclear war. When Obama reignited the nuclear arms race last year, they were silent. Furthermore, their McCarthyite tantrum regarding the election and Russian hacking has only increased the chances for nuclear confrontation with Russia.
"New Nuclear Arms Race"
"New"?? Really? Have you been hiding in a hole, Alex?
He won't do that
It would go against the grain of what he is doing.
"To initiate a war of aggression…," said the Nuremberg Tribunal judges in 1946, "is not only an international crime, it is the supreme international crime, differing only from other war crimes in that it contains within itself the accumulated evil of the whole."
That includes Iraq War 2003, which Bush and Clinton pushed hard for; it plausibly includes the effort to overthrow Libya's government, led by Hillary Clinton, as well as the massive covert regime change effort that aided the rise of ISIS in Syria, the one overseen by Obama's government. And then there's this, the extrajudicial assassination program:
Today, the world's greatest single campaign of terror entails the execution of entire families, guests at weddings, mourners at funerals. These are Obama's victims. According to the New York Times, Obama makes his selection from a CIA "kill list" presented to him every Tuesday in the White House Situation Room. He then decides, without a shred of legal justification, who will live and who will die. His execution weapon is the Hellfire missile carried by a pilotless aircraft known as a drone; these roast their victims and festoon the area with their remains. Each "hit" is registered on a faraway console screen as a "bugsplat".
And of course it was Obama who cut off nuclear arms reduction talks with Russia and initiated the "new nuclear arms race" with his $1 trillion nuclear weapons modernization program. A long legacy of war crimes and reckless foreign policy, that's been the United States since the end of the Cold War (which the deep state is desperate to re-ignite, to justify their bloated budgets).
Wait, did I leave out the obligatory "Yes, Trump is an idiot, but. . ."
But, he's not as dangerous an idiot as Hillary Clinton, the neolib/neocon war pig, would have been, what will full corporate media and Deep State support. It's better for the American people to have the media and the deep state fighting tooth and nail with the Jacksonian jackass in the White House, than to have Hillary Clinton leading the Empire into World War III.
(standing applause)! i will refer to this often. also need to find a place for better coffee. tyia
@photosymbiosis: Gee I wonder where you stand and who you voted for…
Alex did mention Obama's $1 trillion nuclear boondoggle.
Also, Trump is the Deep State's choice to follow Obama – they are *not* really fighting him, regardless of the garish establishment theater; he is as much the elite's servant as Clinton would have been – in fact he is indeed surprisingly a little easier to control and less dangerously volatile than she would have been. Trump is doing a 'fine' corrupt job expanding the military, justifying the obscene 'defense' budget and failing to de-escalate military build-ups and unnecessary military bases around the world.
When a nuclear bomb explodes, it doesn't matter who fired it.
Yes, people washed over many facts bc CrookdClintO was part of a trio bent on fooling many. They did fool many women. The CrookdClintO Foundation closed its international branch bc the need for under the table foreign currency dealings has evaporated. Just think of the great sums of money deturned from "doing good' just bc PresCrookdClintO could not just volunteer in some established charities as the RedCross or MakeaWish– all the duplication moneys spent were profits to the CrookdClintOs personal family wealth.
Except of course that much of the Deep State is peachy keen with a new Cold War. After all, they backed the Obama arms increases and the "Pivot to Asia."
the "intercept" hated hillary and the evil clinton machine. by doing so they gave tacit support to bunko don and russia. i bet glenn is just proud as punch about what he's done.
really? ROTFLMAO…. really?
apparently you are not a regular reader of TI.
Are you afraid of Russia? or Russians?
You're a Total Idiot. Away with you!
from 2014:
US [ruling class] plans to invest $1 trillion [of the public's wealth] in nuclear weapons arsenal
paranoia and delusions of grandeur will drive America into deeper bankruptcy than it already is in.
Obama signs his last Pentagon budget: A legacy of war and reaction
[[[ "Mr. Trump must be careful not to upend decades of successful efforts to reduce bloated nuclear arsenals,"]]]
Nukes are like politicians and psychopaths:
1) The world will always have too many.
2) They regulate your life with them.
3) They are against term limits.
[[[ greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes ]]]
Trump's not a politician. He's fighting against psychopathic politicians. Like General Custer.
When the world finally comes to its senses and accepts that most politicians are psychopaths — 2% of the total population — and that a psychopath wants to enslave you with its weapons of mass destruction… is when the world will come to the realization that we won't need nukes when we don't need politicans.
We currently have enough nukes and psychopaths to destroy all living creatures on the planet about 500 times.
This is jsut a continuation of Obama's policy
imagine a world without nuclear weapons…
because every nation signed a treaty to dispose of them and every nation monitored every other nation disposing of them and every nation continues to monitor every other nation to prevent the re-building of them….
yeah- that works too…..
You are not one of those Susan Sarandon elect Trump because he will bring on a revolution types are you?
1. susan sarandon is a wonder person
2. hellary clinton acts like a traitor and proposes to throw the US to the lions
3. donald trump has a headwind
4. the only people revolting against the people of America are wallstreet thieves
have a nice day
Well, there are three nations that have refused to sign- and all are rather threatening to neighbors and residents alike. (I am referring to Israel (Remember the USS Liberty!), Pakistan (Hosts of Bin Laden and future suppliers of Saudi nukes), and India (Who shows that Hindu Fundamentalists can be mean too).)
Then there is North Korea, who are a bigger threat to their own people than their neighbors. (They certainly killed far more innocent people than Libya did in-or before- the Civil War there.) Why we have not taken them on is beyond me.
Everyone still happy that Hillary lost?
"Oversimplifier Oversimplifies for Simpletons," This and more Hot Take News at 11.
(Can it, moron. You're on the wrong site.)
I just asked a simple question. How do you feel about spending $1 trillion dollars to modernize the nuclear triad? Christ the US could just explode those nuclear devices in place and kill the majority of people living in the Northern Hemisphere.
Everyone still happy that Hillary lost? {…} How do you feel about spending $1 trillion dollars to modernize the nuclear triad?
Clinton was the Stay-the-Course candidate who invoked Obama 's name incessantly. In turn, it was President Obama who authorized a nuclear modernization program that would cost $1 trillion:
Hillary would have already started WWIII, genius. You'd be a crushed carbonized husk, or a small collection of disassociated gases and water vapor floating in the stratosphere.
[[[ Hillary would have already started WWIII, genius. ]]]
She would've started WW III on Inauguration Day.
Putin surfed and then "pinged" the whitehouse.gov website.
very much so.
the Donald cannot do anything that the majority cannot reverse – and he will suffer blowback in the process of attempting so.
Hellary however, WAS A TRAITOR to the sovereignty of the US with her traitorous TPP – which is the same styled framework that the colonists revolted against in 1775. I hope she burns in hell.
You do realize that Trump can start a nuclear Armageddon without anyone's approval don't you? Trump just went around the courts to deport illegal emigrants without due process. That action will not stand. Trump asked the FBI to limit its investigation into his campaign and administration's ties to Russia in the last three weeks.
How possibly could Hillary be worse?
Yes. I'm very happy that Hillary lost. Trump is far from ideal, but compared to Hillary, he's sane and safe and responsible.
He's INSANE by any standard metric you ciykd employ.
Yes. Absolutely.
"the U.S. could safely reduce its deployed nuclear force by one third. "
I would rather they reduce our overseas bases and commitments by one third.
Well, it's not like NATO has done much in response to IS's attacks on it's members' territory.
Of course, why not work to ban ICBMs instead of nukes? ICBMs are and were designed as terror weapons to target cities. They are the only weapons to carry heavy warheads. They are also comparatively easy to find.
Welp. There's comfort in knowing that when nuclear war does come, at least it's gonna be quick.
….. not if you're far enough from the blast zones. Expect days, months or a couple years of excruciating radiation poisoning from fallout. Move to the East or West Coast if want to go out with a bang.
Putin and Trump both pine for the good old days of cold war and hair trigger alert apparently. Sides of the same coin you could say…
Do you know what you call an educated person with no common sense?

Chelsea boss Antonio Conte is on the lookout for reinforcements this summer ahead of their return to the Champions League.
The Blues tried to sign Spanish striker Llorente in January but failed to get a deal done.
The 32-year-old is seemingly back on Conte's radar this summer as he looks to add a experienced reserve striker to his ranks.
And Italian outlet Transfermarketweb claim that a transfer is now 'almost done'.
Llorente joined Swansea from Sevilla last summer and scored 15 goals in 35 appearances for the Welsh club last season.
It is said he is now eager to move on from the Swans and is 'enthused' by the chance to work with Conte next term.
The pair enjoyed success together while at Juventus a few years ago and Llorente is keen to link up with the Italian tactician at Stamford Bridge.
Llorente will be signed as a back-up option in Chelsea's attack.
Conte and co look set to miss out on top striker target Romelu Lukaku after Manchester United agreed a stunning £75m with Everton.
Chelsea are said to now be keen on Real Madrid star Alvaro Morata while Andrea Belotti of Torino is another potential option.
Despite their Premier League success last term, the Blues have struggled to get their deals over the line this summer.
Chelsea's only main piece of transfer business so far this summer has been the free acquisition of ex-Manchester City goalkeeper Willy Caballero.
The west Londoners are also working hard to tie up deals for Tiemoue Bakayoko, Antonio Rudiger and Alex Sandro.

Five-Minute Film Festival: Flipped Classrooms I really enjoyed Mary Beth Hertz's excellent blog published earlier this week, "The Flipped Classroom: Pro and Con" -- one of the most concise and balanced views I've read on the buzz-wordy concept of flipping the classroom. Advocates say that "flipped classrooms" help overburdened teachers differentiate their instruction to reach more learners, provide an avenue into more hands-on and student-driven learning during classtime, and shift the teacher's role from "sage on the stage" to learning coach and facilitator. Critics say it's just a fad, relies too heavily on rote instruction, and doesn't go far enough in making the needed changes for teaching and learning reform. I've rounded up this list of videos so you can learn more about the challenges and benefits of flipped classrooms.

When we come across new technologies or digital platforms for the first time in further and higher education (HE), how do we decide what the technology does or should do, and how we can use it to help us? In the digital student project we have been investigating incoming students' expectations of the digital environment in HE. Institutions will be working to meet or manage expectations as hundreds of thousands of new students arrive in September but it's no small task to build a picture of students' hopes and aspirations when there are modules to rewrite and technology to update over the summer. Clearly experiences of digital technology while at school will be a major influence, so we have looked closely at the sort of technologies schools own and how they use it. In the classroom Coming to an understanding of the use of technology in schools wasn't straight forward.

Lazerman became the ruler of the darkloids and his speed/power are immense. One disruption blast could end most opponents and his speed is on an extremely high level. I think Simon's robot has enough defense to endure those shots long enough for him to take the win. Lazerman's abilities won't be enough to win this battle and he actually takes a loss. Simon (Gurren Lagann) wins.

Automatic Sliding doors have recently become a very trend among interior designers and architects. They always recommend the construction of sliding doors not only to provide your house with a modern look and feel but also due the scope for space left in your house. This will leave us with other options to integrate several things that would require more space.
In this growing digital era, everything has become automated even sliding doors. Automatic sliding doors are designed in several manners, whether it is the traditional two panels or the overlapping panels or other methods. Automatic sliding gates are electrically designed and this is why there is no requirement of manual labour. These gates work automatically due to its interesting built manner.
Safety Gates come first
These gates provide an alluring design and a fine finish with an attractive look. Independent houses, industrial institutions, etc. build automatic sliding gates for additional security purposes. They have additional security devices integrated within them that prevents unauthorized intruders from entering the required premises.
Specific systems for security purposes have been incorporated in the auto sliding gate kits even by the manufacturers in order to meet the customizable requirements of the customers.
The suppliers who are very quality conscious will always be contacted by the best manufacturers for flexible customization. The choice of door depends on what exactly your requirements are. There are several types of price structure and an extensive competition in the market and they all wish to include the best features in their provided auto sliding gate kits.
Automated gates are growing in prominence are here are a few reasons:
1. Extremely convenient: Auto sliding gates allow entrance into a property without getting out of their cars like the situation when it comes to opening manual gates. It is an advantage and reduces extra labour of work. It locks automatically even if you forget you lock the gate.
2. Provides best security: As the name suggests, automatic gates are integrated with safety beams, automatic locks and other safety boosting features that are provided by the suppliers in the auto sliding gate kit for better manufacturing and installation purpose.
3. Does not take up much space: There is scope for extra space to integrate slots for other structures such a parking area or landscapes when automatic sliding gates are installed. Their sliding feature provides more space in comparison with the normal swinging gates feature. Specially, properties with small spaces benefit a lot from this.
4. Built for better function: Automated sliding gates provide more advantages than swing gets which are manually operated under many circumstances. Sliding gates open wider in comparison to the latter and are also better in terms of functionality when it comes to a sloping driveway.
5. Durable Product: The auto sliding gate kits include a precision technology and built with functionality and durability in mind. They can withstand any kind of weather and operated under harsh weathers as well. It is a one-time investment that you can afford for the sake of security.
6. They are very visually appealing and are value-added: These gates are manufactured in a way to complement every kind of personal preferences. They are customizable when it comes to choose of material and additional installation requirement.
All the auto sliding gate kits include a motorized system which are always sustainable and can even support heavy-duty tenders. The motorized applicant must ensure extreme reliability that will provide a long-lasting installation. Several external features can also be installed by requesting and providing advanced details regarding the features to your manufacturers.

text: Fourth Order is a freshly formed drum and bass collaboration between talented artists and good friends with one vision in mind. To create and perform some of the most original, twisted and dark, neuro drum and bass ever to hit your ear drums. Fourth Order consists of three artist names already at large on the drum and bass scene. Jimmy and Dan (Volatile Cycle) Steven (Barbarix) and Matt (Block Dodger). All with multiple releases on well known labels such as RAM, Renegade Hardware, Viper, Methlab, Neurofunk Grid, and Close2Death. Fourth Order was born out of a friendship founded through the task of writing music for the now famous Boomtown opening and closing shows. In winter 2015 Matt pitched the idea of some of his lyrics to Boomtowns creative producer regarding an opening show. Then later in early 2016 he was given the go-ahead to start producing the shows music. Matt immediately started gathering the best and freshest minds in UK drum and bass and contacted Dan and Jimmy (Volatile Cycle). That year they worked together to Produce the Boomtown track "The Revolution" which was mixed down by Steven (Barbarix) and premiered on boomtowns monster new drum and bass stage Sector 6. This was the first time the four producers met in person to watch the show and instantly became friends. Last year Steven, Dan, Jimmy and Matt produced the hugely popular Boomtown track "Behind the mask" which closed down Bang-hai Industries and Sector 6 in a spectacular show. The track then featured in the official Boomtown after movie. Now this year they return as a single unit. An embodiment of their passion and drive to push the boundaries of drum and bass. They are Fourth Order.

Check out the new Video from Sharon Van Etten – Your Love Is Killing Me
Sharon Van Etten "Your Love Is Killing Me" from new album 'Are We There' out now worldwide on Jagjaguwar
After moving back home to New Jersey and working at Perryville Wine and Spirits, Van Etten saved up enough money to move toBrooklyn, New York in 2005, where she was encouraged by Kyp Malone of TV on the Radio to pursue a career in music. Malone said she'd approached him at one of his shows and gave him a CD-R of her songs. Van Etten was friends with Malone's brother, Colin, in high school. Malone normally doesn't listen to fan submissions, but "he put Van Etten's album on and fell in love. 'She's been silencing rooms in drunken bars for a long time,' Malone says. 'Really very arresting. She just sends me.'" Malone ended up playing Van Etten on his Guest DJ set for NPR's All Songs Considered.
Van Etten released a number of hand-designed and self-released recordings prior to her debut studio recording. These were hand-painted designs she would sell on her website, as well as postcards, and sometimes t-shirts. She also worked as a publicist at Ba Da Bing Records in order to learn how the music industry worked, but didn't tell them that she was writing and performing music. She got the job via a friend, Alicia Savoy, who she went to college with in Tennessee. She started out as an intern and worked her way up to being a full-time publicist.
Van Etten said that Jeffrey Davison, a deejay on WFMU who has a show called "Shrunken Planet," was the first person to play one of her homemade CDs on his show. Van Etten has become close to Davison and his wife, who have her over for record listening evenings.
May 2014 brought about the release of Van Etten's fourth record, Are We There on Jagjaguwar. Van Etten self-produced the record withStewart Lerman. The record includes Torres' Mackenzie Scott, Shearwater's Jonathan Meiburg, Lower Dens' Jana Hunter and Efterklangaffiliate Peter Broderick. Van Etten said some of the instruments in the recording of the album were used by John Lennon and Patti Smith. The album was recorded at Hobo Sound Studios in Weehawken, New Jersey and at Electric Lady Studios in New York City

As a result of climate change and urbanization, more frequent flooding, diffuse pollution, and unsatisfactory combined sewer overflows are impacting on the quality of life and wellbeing of urban dwellers, and on the ecological status of urban water systems. Sustainable drainage systems (SuDS) have been developed to manage stormwater at source and restore pre-development hydrology, control diffuse pollution and, if vegetated, promote ecosystem services and reduce urban heat islands. Existing knowledge about SuDS performance is not exhaustive, especially regarding the influence of their design and configuration (plants, media, drainage) on hydrological processes, contaminant removal mechanisms, and on long term performance. This PhD project aims specifically at investigating biofiltration systems since these have been identified as a promising technology for retrofit in dense urban areas due to their flexibility in design and comparatively small footprint. Hydrological and bio-chemical processes occurring within biofiltration systems will be investigated through laboratory and field studies aimed at optimizing their performance. Numerical modelling of biofiltration systems will be evaluated as well as development of methodologies to allow for their inclusion in catchment-scale models for planning and decision making purposes.
Your studentship will be part of the Water Connected City programme of water@leeds, one of the largest interdisciplinary centres for water related training and research in the world. You will be based in the School of Civil Engineering, with access to world class laboratory and wider campus facilities, and will spend significant periods of time shaping and transferring knowledge and conducting fieldwork with our partners Arup. You will also form part of a large and vibrant postgraduate research community, extending right across the University of Leeds.
Universities in the United Kingdom use a centralized system of undergraduate application: University and College Admissions Service (UCAS). It is used by both domestic and international students. Students have to register on the UCAS website before applying to the university. They will find all the necessary information about the application process on this website. Some graduate courses also require registration on this website, but in most cases students have to apply directly to the university. Some universities also accept undergraduate application through Common App (the information about it could be found on universities' websites).
Both undergraduate and graduate students may receive three types of responses from the university. The first one, "unconditional offer" means that you already reached all requirements and may be admitted to the university. The second one, "conditional offer" makes your admission possible if you fulfill some criteria – for example, have good grades on final exams. The third one, "unsuccessful application" means that you, unfortunately, could not be admitted to the university of you choice.
All universities require personal statement, which should include the reasons to study in the UK and the information about personal and professional goals of the student and a transcript, which includes grades received in high school or in the previous university.
Applications are invited from candidates with or expecting a minimum of a UK upper second class honours degree (2:1), or equivalent, in an Engineering or Science discipline with a strong environmental or water focus.
Value: The studentship, which is open to UK/EU students in the first instance, will pay the full tuition fees at £3,975, as well as providing an annual maintenance of £13,863.

Halfway through 2016 and ReflectingJune 16, 2016 on 4:29 pm by Michael Grey | In Humour, News, Photographs, Pipe Bands | Comments Off on Halfway through 2016 and Reflecting
I think it's the early sunrise and especially bright eye-squinting mornings, just a little south of the 49th parallel, that reminded me today that we're almost at the halfway point of 2016. Whoosh! That's how time goes – and that's how time flies. And so, as not to forget, and maybe omit something from what will surely turn out to be a mighty and interesting late-December 2016 summary, I thought I'd jot down a few personal highlights of the year that's been so far. Not for you, of course, but for me! Me. Me. Me.
When thinking, in processing thoughts, just what makes a person think – of anything? What ignites a thought? A chance meeting with a new acquaintance or old friend? An email, a text, a dog's bark, the weather, an online video, the news – the cat licking it's arse – what random action or environmental thing triggers (and apologies in advance for using that word) a thought or thinking? And, again, in this case, thinking as reflection.

Piping Today: A magical winter week in GlasgowFebruary 24, 2016 on 5:03 pm by Michael Grey | In From Piping Today Mag, Pipe Bands, Tips | Comments Off on Piping Today: A magical winter week in Glasgow
I once read something somewhere about the spiritual power of making music in a group. The words I recall spoke to group music creation in a sacred sort of way. Making music with others joined energy and life forces and, well, made magic. Magic a word used here, I think, to describe the indescribable. And the indescribable, to me, usually stands as the best and worst things in life and, from time immemorial, inspirational fodder for the poet. Anyway, these hazy recollections stayed with me and it was only in the last week of January did they again burble up.

A Musician's Struggle: Rehearsal SpaceJanuary 9, 2016 on 7:51 pm by Michael Grey | In Pipe Bands, Random Thoughts, Solo Piping, Whinges | Comments Off on A Musician's Struggle: Rehearsal Space
When you're a musician it's never easy finding practice or rehearsal space. In big cities especially, high density and thin walls make snagging the right reliable place tricky in the extreme. But when you're a piper – or group, like a pipe band – the challenge is layered with bias, barriers and brutal complication. I've found myself "practicing" tunes in some seriously ropey places: the B3, or third sub-level, of an underground parking lot on Bay Street across from Toronto City Hall, pretty much every men's WC of any indoor contest or event I have ever participated in and the reclined front passenger seat of a Renault 5 (in the pouring rain while parked on Dunollie Terrace, Oban).

A couple of years ago I asked John Slavin, MGD (Master Graphic Designer) if he would work up a logo for me, for Dunaber Music. And so, after a little quick consult, he did. What John came back with, with his first sketches, is what I use today. As I have said time and again (usually to an open-mouthed gathering of rolled eyes): you just can't beat the impressive presence of a piper wearing a Balmoral bonnet.

Piping Today Magazine – Grey's Notes: "Piping: No Excuses"March 17, 2015 on 3:36 pm by Michael Grey | In From Piping Today Mag, Pipe Bands, Solo Piping, Stories, Tips, Whinges | Comments Off on Piping Today Magazine – Grey's Notes: "Piping: No Excuses"
My Dad always said that life moves forward at a pace in tandem with a person's age. So when you're 10, life seems to move along at a grindingly slow 10mph. At 10 a kid feels like it'll take forever for summer holidays to come and even longer for the next happy birthday. By age 20, a healthy savings account is a nice idea for dull, boring people; but for most there's nothing but countless, unplanned days of never-ending fun. Your forties come along and it's all, whoa, something's happening here: life is moving way past school zone speed. Bill made it to an Autobahn-friendly 86mph before he pulled over and stopped in the parking lot of the inevitable. And this is all to say, the obvious, you'll know that's my specialty; and that is, a person's age goes a long way to inform how life is lived and, in turn, how life is understood.

Cowal Games 1929March 15, 2015 on 7:07 pm by Michael Grey | In Photographs, Pipe Bands, Solo Piping, Stories, Tips, Video | Comments Off on Cowal Games 1929
Say what you like, but I've always liked Cowal Games. Of those I recall, my memories are nothing but the happiest – or – at least – really good. OK. Not always, "really good", but memorable. Yes. Memorable. Well, mostly memorable, but usually fun. Cowal, as much, if not more, than other contests, has given me some stuff to remember. I've socked it all away and stand today with a good few stories to regale the unsuspecting at the drop of a hat. Cowal Games: you rock.

WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. Whenever you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and investigate which functions you want to attain.
Wireless or PoE, which is the greatest? As a mature technician who have four years in video recording monitoring industry, my answer to this question is PoE is the suggested choice.
WiFi is some sort of wireless technology that allows network devices transmit data through wireless indication (2.4GHz UHF music group, 5GHz SHF band).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is actually the advantage of Wireless.
But there are two downsides on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cams have the ability to operate with electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have many things to consider including power rate of WiFi device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters interior.
When WiFi devices are working outdoor without barrier, the transmitting distance will be much considerably.
To extend the Wi-fi coverage or distance, you can set up WiFi access point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 ft) indoors and a greater range outdoors.
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet wire (Feline5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP video cameras support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electricity rate is to 15.4 W of DC electric power (bare minimum 44V DC and 350mA) to each device.
In order to provide power supply for high electric power utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. CONS AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable connection, there is absolutely no signal interference, no sign jamming.
For properly working of PoE devices, Power sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network change, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Making sure the WiFi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that WiFi IP video cameras are trusted for non-professional inside security, and PoE IP surveillance cameras are installed for outdoor security system. But if you select Wi-fi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which type of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cellular IP video cameras that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or bright); what perfection of data would you like to record? (HD images with or without audio) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Obviously, this feature will depend on the surroundings where you want to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the kind of zooming functionality, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your neighborhood digital store.
Always obtain a test set up as this will permit you to determine the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to set up the gear in an effective manner to make certain you receive the best image and sound quality.
