I use a software called connecity ( http://connectify.me/ ) to turn my laptop to a wifi router and provide other devices with internet using my DSL connection. But after i switched to the ubuntu 11.10 I can't do this thing. Is there any linux software or trick available to do this?
yes, Ubuntu and many other Linux distributions contain a feature called "ad-hoc network" and "wifi tethering"
You can create an adhoc wifi and make near clients to access your network.
For this, you need some connection (cable connection, or another wifi connection but with a second wifi adapter).
Remember, you can't use the same adapter as WiFi receiver and wifi spot.
You go to network settings ->
You create a connection and select
you can specify a password and enjoy.
there is bug currently in Ubuntu so there is work around for making ad hoc wifi access point, queting bellow:
"connecting with shared with other computers connection in NetworkManager. Other computer gets IP but NetworkManager disconnects the shared connection after half a second. This same setup worked perfectly fine in 11.04. Is there any fix, workaround or alternative way to share a connection with another computer over an Ethernet cable. (I can downgrade to 11.04 but I'd rather not ).
EDIT: found a workaround The workaround for now is to set IPv6 options to Ignore and then sudo killall dnsmasq. Reconnect and it should work."
I done in on my laptop with Ubuntu 12.04 and mine working fine now.

A friend and I have started a project using code from another project, that is covered licensed under GPL. We have distributed it freely on our website, and under its download button, we've added a direct download link to the modified source code also for free. At the about section of the application, we have credited the guys who built the original code. Does the fact that we have a different project name violate the terms of the GPL? And also, if we include the original GPLv2 notice from the original app does that help us comply with it? If not, please state exactly what we have to do to comply with the GPL. The code we're using is an older version, released under GPLv2, and that project has been discontinued, and moved to a different one, where they're still developing. We haven't used any of their current coding, which is released under GPLv3.

How do we avoid GPL violation when modifying and releasing a program using code coverd by this license?
The GNU General Public License v2 reads:
That means that when your project is based on GPLv2 software, it also has to be released under GPLv2.
For that reason the GPL is often criticized for being a "viral" license - using GPL code in a project "infects" it with the GPL and prohibits you from releasing it under a different license.
To do so you have to:
You avoid a GPL violation by simply adhering to the GPL license terms. From what you describe (your source is available, license terms are still GPLv2, source acknowledged) you've done enough.
You don't need to include the original GPLv2 notice; your own version is sufficient. However, you do need to acknowledge the copyright of the initial contributors.
Using a new project name is no violation of the GPL. It's in fact the norm for forks of OSS projects, and might be required under trademark law.

A better-than-expected increase in last week's US refinery utilization rates is welcome relief to recent concerns that weak demand was contributing to a surplus of crude oil.
A lift in US refinery utilization rates to 85.7%
from 83.5% last week, well above expectations of around 84%, is
welcome relief to concerns that low demand was contributing to
a surplus of crude oil, says Lachlan Shaw, an analyst at
Commonwealth Bank of Australia.
West Texas Intermediate crude for May delivery settled up 24
cents, or 0.3%, at $96.58/bbl onthe Nymex Wednesday, the
highest settlement since Feb. 19.
ICE Brent crude settled up 33 cents, or 0.3%, at $109.69/bbl.
US crude stocks advanced to 26.9 days of supply last week, near
highs of 27.1 days of supply recorded in the week ended March
For the same week in the past five years, US crude oil stocks
averaged 24 days of supply, Shaw says. WTI crude for May
delivery is up 16 cents at $96.74/bbl on Globex.

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with "drag and drop" capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.
Is 2016 the peak for US gasoline demand?

We continue our series of local political interviews, talking with 20th District State Representative Jody Richards, who lists his accomplishments in more than three decades in office.
"We have created more net new businesses than any county in the state in the last 10 years," says Richards, "even counties like Jefferson and Fayette which are much larger than we are. We have a great working relationship in this community. Look at things like the SKyPAC and how Western is growing. And so I just want to be a part of moving this community forward. One other quick thing is our education system. We have one of the best education systems in America. We have three high schools in the top three percent in the entire country. And our university is growing faster than any public university in the state and our community college is doing the same so why change what is doing well right now?"

What are your favorite comfy shoes that aren't sneakers, men of woot?
In desperate need of some new shoes and I was just going to go out and get another pair of the merrell's I already have, but I thought it would be interesting to know what everyone else wears.
My priority is comofort, but I don't mind if they look nice as well.
11 Answers answer
I've been getting all of my shoes of late from Red Wing. I personally like their work boots for the ankle support and crush proof toes, but they sell "regular" shoes as well. I have a rather wide foot for its length and I have trouble squeezing into other brands.
My Sanuk Vagabonds are my most comfortable pair of shoes I own, I also have a pair of Scurvy's and Standards that are just as comfy.
I got a pair of Croc's Santa Cruz loafers, they are wicked comfortable and they don't look half bad. However, I normally wear a size 12, but I had to get a size 11 in the croc's for a good fit.
I love my Red Wings. Most comfortable shoes I've ever owned!
I have an old pair of Nautica boat shoes that are great. Really comfy, slip on/off, work well with or without socks.
They don't make the exact style that I have anymore, but I'm sure they're all about the same.
Keep all the responses coming!
I think those vagabonds look kinda ugly, but the standards look pretty decent.
I have a pair of Merrell's that I wear with khakis and I love them. I love them so much, in fact, that I'm on my third pair of them.
When I need something more dressy I go for Rockport Dressports wingtips. Super comfortable, and they wear like iron.
I'm not a guy, but I love Born shoes and they make shoes for men as well. They are comfy and last a really long time!
Another vote for Red Wings. I recently had to get a new pair of boots for work. Picked up a pair of Timberland Pros. Easily the most comfortable boots out of the box I've ever had. They're just about as comfortable as my Asics right now.
My Sorel winter boots are awesome comfortable and waterproof to about 2 feet of standing water. However they are a bit warm for non-winter use.
I also have a pair of Clark's sandals that are great. Easily the most comfortable pair of sandals I have ever owned, and I've gone through a lot of sandals over the years.
The comfiest pair of shoes I own has gotta be Vibram 5 fingers... not sure if they count as sneakers though...
Other than that I pretty much stick to sandals so Rainbows

[Fix] Combobox Default Value
We're all familiar (I think) with the problem that values are set on comboboxes before the store loads meaning that you end up with the value displayed in the box instead of the text you want. The solution is to call setValue after the store loads. But, of course, that isn't always appropriate. You might want to use the 'value' config, or call setValues when your Dialog loads or something of that sort.
If ComboBox.js were modified to add an onLoad event to the store when the combobox is constructed, then this would solve the problem. Something to the effect of:
this.store.on('load',this.onLoad,this); .... onLoad: function() { this.setValue(this.getValue()); }
17 Sep 2007 1:58 PM #2
do combo.setValue(fieldValue), and then combo.setRawValue(displayValue)
the second call will keep the hiddenField's value intact

NYU Florence offers an exceptional academic program for undergraduate students throughout the academic year. Most content courses are taught in English, while some courses are offered in Italian to students proficient in the language. One way to become familiar with the Italian culture is to study the language. Students are required to take an Italian language course that matches their skill level. Approximately 375 undergraduates per semester study Italy's history and its extraordinary art, literature, philosophy, and architecture, along with the political, cultural, economic, and social issues that play a role in shaping Europe's future. Courses in business, film, photography, psychology, music (in spring semesters), and studio art are offered and will make use of the unique resources only available in Italy. Whenever possible the courses use Florence, Tuscany and often other parts fo Italy to ground your learning in the actual context in which it takes place. Classes are held at the La Pietra estate and at downtown locations. For students with advanced Italian language skills, courses can be taken at the University of Florence.
Upcoming Application Deadlines
Priority: February 15
Regular: March 15
Applications received after March 15 will be reviewed on a rolling basis. Admission will be granted only when space is available and time allows for required travel documents to be attained.
At NYU, we firmly believe that a well-balanced liberal arts education is the best preparation for law school. Students taking courses in the pre-law track at NYU Florence can take courses that compare and contrast the legal systems of Western Europe and examine issues involving law and human rights.
A center of medieval European commerce, Florence flourished as a major banking hub. Today, Italy faces budget deficits and meeting the standards of the European Union. Through the College of Arts and Science (CAS) and the Stern School of Business, economic and business students at NYU Florence specialize in the economies of Europe, which includes a population of 731 million people in 50 countries.
LPD convenes some of the world's foremost scholars, policy makers, practitioners, business leaders, public intellectuals and artists whose ideas and work have made a significant cultural or intellectual contribution to global society and the revival of the spirit of humanism for which Florence is known. They gather at Villa la Pietra, New York University's exceptional site in Florence, to confront some of the most intractable issues of contemporary society through the creative interplay of ideas and perspectives. LPD fosters the creation of partnerships across disciplines, cultures and institutions, as an established center in the heart of Europe attached to an American University with branches throughout the world, and contributes to the emerging global civic discourse that is at the heart of NYU's mission as a global network university.
Students who are especially committed to learning Italian culture and language are invited to join the Florence Immersion Program. Take the next step toward fluency with special courses designed for students with Intermediate Italian or beyond.
To complement the curriculum, many professors organize local site visits as well as out-of-town field trips. These activities are mandatory and appear on each professor's syllabus. Most art history classes include visits to churches, museums, and villas in Florence and Italian cities to view artwork in context. Local museums are an integral part of many classes, and past visits have included the Uffizi Gallery, the Bargello Museum, l'Accademia, San Marco Museum, and the Medici Chapels. Recent trips outside of Florence have included visits to the Vatican museum and Saint Peter's Basilica in Rome and a viewing of Leonardo's Last Supper in Milan. The Etruscans class regularly visits the archeological museum in Bologna and stops at nearby ancient ruins; the Italian opera course supplemented in-class discussions by attending a performance of Puccini at Verona's opera house; or a backstage tour of La Pergola, the opera house in Florence. Students often opt to take advantage of local holidays and the weeklong spring and fall breaks to travel through Italy and Europe.
'Italian Identities as Told through Cinema: Il cinema racconta gli italiani' is an insightful way to study the evolution of Italian culture, history, and society. It introduces students, both foreign and Italian, and the general audience to contemporary topics in Italian society and investigates these issues through the medium of film.
At each screening, Prof. Vito Zagarrio, Italian Identities film festival director, cinematic director and Professor of Cinema at NYU Florence and Roma3, and Professor Ermelinda Campani, Spogli Family Director of Stanford's Breyer Center for Overseas Studies in Florence and Professor of Film Studies, will introduce and moderate an open discussion with a special guest speaker associated with each film.

I want to know whether my browser is using SSL or TLS connection if I see HTTPS.
I want to know for IE, Firefox, Chrome and Safari. I want to know the protocol version.
I want to know whether my browser is using SSL or TLS connection if I see HTTPS.
I want to know for IE, Firefox, Chrome and Safari. I want to know the protocol version.
There are several protocol versions : SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2. Internally, TLS 1.0/1.1/1.2 are SSL 3.1/3.2/3.3 respectively (the protocol name was changed when SSL became a standard). I assume that you want to know the exact protocol version that your browser is using.
According to what is described on this blog post, Internet Explorer can display the protocol version information. Just hit File->Properties or Right-click -> Properties, and a window would open, under Connection, you'd see something like:
As of today, Firefox supports TLS 1.0, TLS 1.1 and TLS 1.2. You can see the negotiated protocol version if you click the padlock icon (on the left of the URL), then More Information and then under the Technical Details.
Chrome can display the version. Click on the padlock icon; a popup appears, which contains some details, including the protocol version. example: (verified on version 21.0.1180.82)
Opera shows the protocol version in a way similar to Chrome: click on the padlock icon, then click on the "Details" button. e.g. (verified on version 12.01):
For browsers which do not show the information, you can always obtain it running a network analyzer like Wireshark or Network Monitor: they will happily parse the public headers of the SSL/TLS packets, and show you the version (indeed, all of the data transfers in SSL/TLS are done in individual "records" and the 5-byte header of each record begins with the protocol version over two bytes).
And, of course, the actual protocol version is a choice of the server, based on what the server is configured to accept and the maximum version announced by the client. If the server is configured to do TLS 1.0 only then any connection which actually happens will use TLS 1.0, necessarily.
(Edit: I have incorporated some information from the comments; done a few tests myself. Feel free to enhance this answer as needed.)
Google Chrome
Mozilla Firefox
Internet Explorer
The padlock is to the right of the address bar, but it won't help. Instead
It would be neat if Internet Explorer were consistent with the other browsers. Under the padlock indicator is sensible place to look.
I am still unable to find add-ons or extensions to check ssl protocol version directly from browser session. But what I found is here.
openssl command give ssl information. I don't know much detail on openssl command.
This site use openssl to get extensive information. http://www.serversniff.net/sslcheck.php

If there are 10,000 people, how many people must have the same birthday (ignoring year)?
This is the way I went about this problem:
10000 people / 365 days in a year = 27.397 people per day
$\Rightarrow$ there must be at least 27 people who have the same birthday.
Is this correct?

Let $M$ be a connected orientable smooth manifold.
Is it true that $M$ must have only 2 orientations?
If yes, why?
Let $M$ be a connected orientable smooth manifold.
Is it true that $M$ must have only 2 orientations?
If yes, why?
I am also trying this question and again like you do, I am only given very basic definitions of orientations using atlas. Let me try first and see if this works, and give me your comments! (By the way I am reading sharpe's book)
Let $M$ be a connected orientable smooth manifold.
We say that an atlas $(U_{i},\phi_{i})$ is oriented if the jacobian of the transformation between two charts at the intersection is positive. (i.e. $\det\mbox{Jac}\phi_{j}\circ\phi_{i}^{-1}>0$)
Let us say that two oriented atlas $(U_{i},\phi_{i})$ and $(V_{j},\psi_{j})$ are equivalent if the union forms an oriented atlas for $M$.
Let $(U_{i},\phi_{i})$ and $(V_{j},\psi_{j})$ be oriented atlases such that its union forms an atlas for $M$. If there exists $p\in U_{\alpha}\cap V_{\beta}\subseteq M$ such that the determinant of the Jacobian $\psi_{\beta}\circ\phi_{\alpha}^{-1}$ is positive, then both atlases are equivalent.
We will use the fact that $M$ is connected! We define two subsets as below
$S_{1}=\{p\in M: \exists U_{i},V_{j}\mbox{ such that }\det\mbox{Jac}(\psi_{j}\circ\phi_{i}^{-1})|_{p}>0\}$
$S_{2}=\{p\in M: \exists U_{i},V_{j}\mbox{ such that }\det\mbox{Jac}(\psi_{j}\circ\phi_{i}^{-1})|_{p}<0\}$
Note that we don't have $0$ as a case because $\psi_{j}\circ\phi_{i}^{-1}$ is a diffeomorphism on the intersection.
Now we have $S_{1}\cap S_{2}=\emptyset$ because suppose we have $p\in S_{1}\cap S_{2}$, then $p\in U_{i}\cap V_{j}$ and $p\in U_{k}\cap V_{l}$ such that $\det\mbox{Jac}(\psi_{j}\circ\phi_{i}^{-1})>0$ and $\det\mbox{Jac}(\psi_{l}\circ\phi_{k}^{-1})<0$. But we will run into problems because while $\det\mbox{Jac}(\psi_{j}\circ\phi_{i}^{-1})>0$, we also have
On the other hand, $S_{1}\cup S_{2}=M$, because if $p$ lies in $M$, it must go into some $U_{i}$ and $V_{k}$ and so the determinant of the jacobian is either $>0$ or $<0$.
Now it is easy to see that both $S_{1}$ and $S_{2}$ are open because taking jacobian, and then the determinant are all continuous functions and both $(0,\infty)$ and $(-\infty, 0)$ are open in $\mathbb{R}$, (so the pre-image is open in the intersection $U_{i}\cap V_{j}$ and hence is also open in $M$.
But there exists a point which both atlas agree (or compatible), this means $S_{1}$ is not empty, and so $S_{2}$ is empty because $M$ is connected.
In a same manner, if both oriented atlases disagree on one point, they disagree everywhere.
Attempted proof to your question
Since $M$ is orientable, we have already found one oriented atlas $(U_{i},\phi_{i})$.
We take the same atlas and give a negative orientation. This can be easily done by post composing $\phi_{i}$ with the operation $L:(x_{1},\ldots,x_{n})\mapsto (-x_{1},\ldots, x_{n})$ to get $L\circ\phi_{i}$.
These are the only two orientations by our previous claim because if we choose another oriented atlas $(W_{k},\lambda_{k})$ for $M$, just choose one point $p\in U_{i}\cap W_{k}$. Then because the determinant of the jacobian is either positive or negative, therefore $(W_{k},\lambda_{k})$ must agree with either $(U_{i},\phi_{i})$ or $(U_{i},L\circ\phi_{i})$.
I think that this question can be easily answered if one analyzes the definitions carefully. Let me recall the following relevant definitions:
Definition 1 An $n$-form on a smooth $n$-manifold $M$ is a function $\Omega$ that assigns to each $p\in M$ an alternating $n$-tensor $\Omega_p$ on the tangent space $T_p(M)$. The $n$-form $\Omega$ on $M$ is said to be smooth if $\Omega(X_1,\dots,X_n)$ is a smooth function on $U$ whenever $X_1,\dots,X_n$ are smooth vector fields on any open subset $U$ of $M$.
Exercise 1: Prove that the set of alternating $n$-tensors on an $n$-dimensional vector space $V$ is itself a vector space of dimension $1$.
Exercise 2: The definition of smoothness of an $n$-form on a smooth $n$-manifold $M$ given in Definition 1 is "coordinate-free" (a desirable situation in differential geometry). Prove that this definition is equivalent to the following one using local coordinates on the smooth manifold $M$:
Definition 2 The $n$-form $\Omega$ on the smooth manifold $M$ is smooth if and only if $\Omega(E_1,\dots,E_n)$ is a smooth function on $U$ whenever $(U,\phi)$ is a coordinate neighborhood of $M$ and $E_1,\dots,E_n$ are the corresponding coordinate frames on $U$ (i.e., $E_i=\phi_{*}^{-1}\left(\frac{\partial}{\partial x^i}\right)$ for all $1\leq i\leq n$).
Definition 3 A smooth $n$-manifold $M$ is said to be orientable if there is a smooth $n$-form $\Omega$ on $M$ which is nowhere zero on $M$. In this case, $\Omega$ is said to be an orientation of $M$. An oriented smooth manifold $M$ is a smooth manifold $M$ equipped with an orientation of $M$. Two orientations $\Omega_1$ and $\Omega_2$ of $M$ are said to be equivalent, written $\Omega_1\equiv \Omega_2$, if there is a positive smooth function $f$ on $M$ such that $f\Omega_1=\Omega_2$.
Lemma The relation $\Omega_1\equiv \Omega_2$ is an equivalence relation on the set of orientations of $M$. If the smooth manifold $M$ is connected, then there are exactly two equivalence classes.
Proof. The reflexivity of the relation follows from the smoothness of the constant function $1$ on $M$, the symmetry follows from the smoothness of $\frac{1}{f}$ on $M$ when $f$ is a positive smooth function on $M$, and the transitivity follows from the smoothness of the product $fg$ on $M$ when $f$ and $g$ are positive smooth functions on $M$.
Let $\Omega_1$ and $\Omega_2$ be orientations of $M$. Let us define a function $f$ on $M$ by the rule $f=\frac{\Omega_2}{\Omega_1}$ (this definition is valid because of Exercise 1 and the fact that $\Omega_1\neq 0$ on $M$).
Exercise 3: Prove that $f$ is smooth on $M$.
Note that $f\neq 0$ on $M$ because $\Omega_2\neq 0$ on $M$. Since $M$ is connected, it follows that either $f$ is positive on $M$ or negative on $M$. We conclude that either $\Omega_2\equiv \Omega_1$ or $\Omega_2\equiv -\Omega_1$. Hence there are at most two equivalence classes. However, we clearly cannot have $\Omega_1\equiv -\Omega_1$. The proof is complete.
I mention the following definition because it is very important in the formulation of Stokes' theorem and in the study of Lie groups (to mention a couple of famous examples).
Definition 4 A volume element on a smooth oriented connected manifold $M$ is a nowhere vanishing smooth $n$-form on $M$ which belongs to the equivalence class of $M$ determined by the orientation of $M$.
I hope this helps!

As racers and engine builders are pushing rpm limits that are higher than ever before, more and more race teams are finding the need to run rearend coolers. If you regularly run extra-distance races of 100 laps or more, you may fall into this category. Don't make the mistake of thinking that you're fine if you aren't burning up your gears or breaking locker springs. Although you may not be tearing up equipment, high heat levels in your rearend may be costing you horsepower.
Whether you run a 9-inch Ford-style rearend or a quick-change, officials at gear specialist Tex Racing say tests have revealed that overheated gear oil in a rearend can cost as much as 10 hp at the rear wheels. This can be a problem because of localized heating. As the ring-and-pinion gears mesh, intense heat is generated at the point of contact. Simply pointing an infrared temp gun at the rearend cover will tell you the temperature of the cover, but not the real temperatures being reached between the pinion and ring gear teeth. On a quick-change rear, the quick-change gears are also a source of localized heating.
Generally, synthetic rearend lubricant should not be allowed to exceed 250 degrees F. Factors that can play a role in heating up the rearend lubricant include engine power, rpm range, traction in the rear tires, gear ratio (the higher the ratio, the more heat it produces), the length of the race, and even the efficiency of the cooling system if one is installed.
Oil Coolers Don't make the mistake of thinking an oil cooler for the rearend is the same as a radiator for your engine. Because rearend lube is so much more viscous than water, an oil cooler must be designed differently. First, they are much smaller because the overall cooling needs of a rearend or transmission is much less then an internal combustion engine. The cooler, however, must still receive a steady flow of cool air to work. Mounting an oil cooler flat against some sheetmetal, such as the rear firewall, will severely reduce its efficiency. If you cannot find an area with good airflow, try attaching an electric blower to move a steady supply of air through the cooler.
Because of the lubricant's greater viscosity, a single-pass cooler is almost always your best choice. The key is to maximize flow through the cooler while minimizing pressure. Oil pressure is your enemy here because horsepower is required to produce it. So the more pressure you are generating inside your oil cooler, the more power you are robbing from your rear wheels. In addition to a single-pass cooler, you should also run coolant lines that have an AN sizing of at least -8, with a minimum of 90-degree fittings. Finally, always try to mount your cooler as close to the oil pump as possible. The farther the pump has to move the lubricant, the more power the oil pump requires.
Oil Pump Efficiency Within the last year, Tex Racing has undertaken a comprehensive research program to determine exactly how to produce the most efficient rearend cooling system possible. But before they could do that, Tex Racing's R&D department had to invent its own "parasitic drag dyno" so it could measure exactly what was going on in the rearend.
The parasitic dyno is actually quite a marvel. It uses a large electric motor to spin a driveshaft to which a Ford 9-inch rearend is connected. The electric motor is precise enough that it can hold its speed within 1 rpm at 9,000 rpm. Instrumentation has also been installed that can tell how much horsepower is required to turn the driveshaft at any given rpm.
The test rearend unit is set up with an oil pump, a rearend cooler, a ducted fan to blow a steady stream of air through the cooler, and all the necessary hoses to plumb everything. On one side of the apparatus, instrumentation feeds back information concerning lubricant temperature and pressure in the front of the oil cooler as well as temperature, pressure, and flow at the oil-cooler outlet.
"The parasitic dyno gives us a scientific testbed that we can use to test one variable at a time," explains Tex Racing's General Manager, Jesse Havens. "The goal is to pull as much heat out of the gear oil as possible while requiring a minimum amount of energy for the pump. In other words, we are trying to find the pump that provides the greatest efficiency with the least parasitic drag."
The test methodology for this system, according to Havens, is to cover the oil cooler and spin the rearend until the oil temperature reaches 180 degrees at a specific rpm. Once that temperature is achieved, the electric fan is turned on to provide air to the oil cooler, and then the team sits back to see how long and at what temperature the oil will stabilize. A more efficient system will cool the oil more quickly and achieve a lower constant temperature at just about any rpm level.
The most interesting finding here is that, according to Havens, the most efficient pump system achieves both maximum lubricant cooling and minimum parasitic drag. In other words, you can have your cake and eat it, too. The key is to provide adequate flow levels through the cooler with minimal pressure. Pressure is the enemy here, because it serves to heat the oil and increase parasitic drag in the pump. If the cooler and lines are constant, you can reduce your flow until the oil temp begins to rise. The lowest flow that still achieves proper cooling will produce the least pressure and require the least horsepower to spin the pump.
When testing different oil pumps, Havens said that Tex Racing found almost every pump on the market moves way too much volume, which increases pressure. At racing rpm levels, between 6,000 and 8,000 rpm, many rearend oil pumps are capable of over 50 psi through a standard oil cooler. Havens says a well-designed system can get by with as little as 5 psi, which translates to a reduction of 2-3 hp in drag. Interestingly, at racing rpm, an oil pump operating at 5 psi is generally pumping approximately 20 gallons per minute, which is ideal flow.
In the course of its studies, Tex Racing determined the need to produce an oil pump with a new style to take advantage of the findings. The result is an internal oil pump that drives off the back of the pinion gear. This direct-drive style of pump, versus a beltdriven pump, has not yet been widely accepted in Saturday night racing classes because a different pump must be installed in each rearend assembly you carry to the track. This can cost a little extra money up front, but Havens says the difference in drag between a direct drive and belt system can easily be 1 hp or more, depending on the type of belt and amount of wear. The Tex Racing pump also uses rotors that are just 0.200 inch thick to bring pumping pressure within spec. A relief valve also vents extra pressure if necessary. The pump is lubricated by the oil in the rearend housing and only needs to be rebuilt whenever you pull your center chunk down for a gear rebuild. Havens says the new pump, while available for any Ford 9-inch rearend, has been particularly well received in the Nextel Cup ranks and has been in winning race cars-including restrictor-plate cars, where minimizing drag is so critical.
Another interesting finding that most Saturday night racers can use is that rearend oil pressure can spike as high as 150 psi if the driveline is brought to racing rpm while the oil is still cold. This often happens in racing if you don't have a chance to properly warm up the car before taking your qualifying lap. Pushing cold gear oil at 150 psi will cost you at least 5 hp, and you can't afford any drag on your driveline during qualifying. Also, Havens says most coolers are only designed to reliably handle 100 psi, and if you are suffering from oil cooler leaks, they quite likely came from cold-oil pressure spikes and not just vibrations from racing.
Havens also stresses that you don't have to take his word for it. If you own an onboard diagnostics system, you can easily configure it to test your oil inlet and outlet temperatures at the oil cooler as well as pressure during a test day at the racetrack. It may not be as precise as Tex Racing's parasitic dyno, but it will give you an idea of exactly what is going on inside your race car.
Here, the rearend is spinning at 2,400 rpm. The oil temperature is rising slowly, and the lighter color indicates aeration.
This shot was taken with the rear gears spinning at 3,700 rpm. The oil being directed over the top of the inside of the housing is dripping onto the carrier bearings as well as the pinion bearing, ensuring that they are properly lubricated.
Finally, we are at racing speed: 7,100 rpm. As you can see, there is lubricant everywhere. This is why it is dangerous to try to lower your lubricant level too much, unless you have an oil pump dropping oil straight onto the ring gear.
Here's the extent of Tex Racing's new oil pump. To keep oil pressure low enough, the pump gears are only 0.200 inch thick.
The pump is driven off of a driveshaft that keys into this hex cut and into the back of the pinion gear. Havens says this is the most efficient system Tex Racing has found so far.
If you race a quick-change rear, Tiger Rear Ends produces a similar oil pump that spins off the back of the jack shaft. Tiger also sells a kit that allows you to mount your oil cooler directly to the axle tube, which is a great way to minimize the complexity of the plumbing.

I mean you can't learn math in a linear order. Can I just read a paper first on a subject I haven't studied and just work backwards? For example, I have never studied combinatorics but I sort of have a fuzzy idea about the paper on alternating permutations by Stanley.
This may in the end, for an absolute beginner, be quite unproductive. Normally introductory texts are written in such a way as to be helpful to a newcomer by first building a knowledge-base of basic facts about a field of mathematics, and then perhaps having a few chapters on selected topics of moderate difficulty towards the back.
I would recommend a compromise. First pick up an elementary text which is well-known and accepted among your peers, or accepted among the people who are writing the papers you wish to read. (This information is not very hard to find.) Then read and study the first few chapters with the basic material thoroughly. Then you may read the advanced paper, and be thoroughly confused, and work your way backwards as you describe.
But without the first step I do believe you will be not only creating more problems for yourself in the beginning, but also in the end, where you may indeed miss the entire point of a paper. Very often top research papers replace a standard part of a big elementary machine with a clever alternative to attack a difficult problem and find a new solution. You will not understand or appreciate this without a basic knowledge of how the solution works in the standard case first.
I think it can be a very good idea to start with more advanced material and work backward to foundations. Certainly, in the case of combinatorics, it is quite reasonable to start out try to understand a particular problem and be brought backwards into the general theory, and Stanley is a very clear writer. To chose an example from my own life, I learned a good deal of real analysis by trying to understand how one proved that $\sum \cos (kx)/k^2$ converged to a periodic function, each period of which was a parabola.
What worries me about your question is the word "fuzzy". If you are going to skip ahead, I would advise you to have a very sharp understanding of those things you do not know yet, but expect to know when you have mastered the more basic material. Choose some particular theorem from the advanced paper and try to write out or talk through a complete proof of it. (Note that I had no trouble stating the above Fourier result and, indeed, watching it occur on my graphing calculator.) When you reach a point that you can't explain, this is when you need to dig back into the foundational material and figure out where that point is explained.
I think this sort of study requires you to be scrupulously honest with yourself about whether you actually know a complete proof, and not to be satisfied until you do. I've seen a lot of students whose "fuzzy" understanding proved, on examination, to be no understanding at all.
Why not? You should try it and see if the approach suits you.
The "tendrils of knowledge" passage is quoted below. It is something that most graduate students experience. I don't think that the author advocates it as an overall way of learning but as:
The title of the question should be edited to avoid the implication that this is one professor's (or any person's) recommmendation of a complete learning method. It is advice to graduate students in a very theoretical discipline, algebraic geometry, where there is so much background to learn that it is rare for specialists in the field to read the proofs of everything before (or after) commencing research. The message is to not be intimidated by the formal complexity of the subject and not to bury oneself only in books while disengaging from talks and research papers.

Maduro said an investigation found the incident was the product of "sabotage by desperate actors who believed that a refinery fire would help them win the elections against late president Hugo Chavez."
CARACAS -- A 2012 explosion that killed 42 people at an oil
refinery in Venezuela was "sabotage," President Nicolas Maduro
said, accusing opponents of being responsible.
Maduro cited an international investigation as finding that
the incident was the product of "sabotage by desperate actors
who believed that a refinery fire would help them win
the elections against late president Hugo Chavez."
Venezuela is South America's biggest oil producer and
firefighters struggled for days to put out the blaze triggered
on August 25, 2012 at the Amuay refinery, which produces 645,000 bpd
at normal capacity. Dozens were also injured in the blast.
The incident was initially blamed on a gas leak said to have
caused the fire and explosion of nine fuel tanks. The blast
tore through homes, businesses and part of the refinery.
Maduro claims the opposition used the incident to try to chip
away at Chavez's popularity. But the late president won the
October 2012 elections before dying of cancer on March 5.
In June, Maduro had accused the opposition of being behind
the blast on the basis of the attorney general's probe, but
this was the first time he cited an international
investigation. The president did not indicate who conducted the
latest probe.
There have been similar incidents at refineries in oil rich
Venezuela in recent months, some of which have also been blamed
on sabotage.
Venezuela has the largest oil reserves in the world, with
the government estimating that at 297.57 Bbbl its reserves
surpass those of Saudi Arabia, which has the world's biggest refining capacity.
Venezuela is also the fifth largest exporter of oil.

That is not sabotage! Mayor maintenance has been seen to be suffering from delays of two o three years, and routine maintenance suffered a significant low. This efect are also evident in the aintenance backlog for pumps and motors.
V K Kapoor
oil refineries are very vulnerable to sabotage. It is great good task to prevent such bad incidence
Jorge Hau
Yes, food shortage, current 29% inflation, increased crimes, kidnapping, everything else that go wrong is the making of the opposition. They control everything, judicial, the state oil company, the army, have nationalized a large number of businesses in the area of agriculture, industrial, services of all kind, power supply but if there is shortage of electricity is also the making of the opposition. They make their army and militia, the judges and police force believe this is a fact: the opposition is worse than the devil itselt. The opposition is so evil that are capable of carrying out such an atrocity as this they claimed in Amuay. They believe it; when the opposition protests, national guards, police, militia, and sympathizers, all are willing to shoot to kill and they do it all the time; they have done it. The opposition is the demon that deserves to be shot. If then the media publicize the deads, it is the opposition to blame and even say that the shooters were from the opposition shooting its own people just to blame the government. This is how they have justified many killings. If the media show a video demonstrating who the real killers were, the government would say it was made holiwood style, special effects to make them look bad. Any similarities with dictatorship elsewhere is pure and only a coincidence.
Brad ONeal
What rubbish! There was video last year after the explosion that said there was a LPG pump seal that was blowing out for days prior to the explosion. A pump in LPG service was blowing out! For days! That is not sabotage. That is incompetence due to putting your cronies in charge and completely neglecting any kind of maintenance. In Venzuela - meet the new boss, same as the old boss.
Paul Tudor
Regarding this issue the claim of the Venezuelan President and the PDVSA CEO are a bunch of lies, since 2002 the oil production declined by 1MM barrels per day, that means there has not been any exploration budget.Now regarding the oil installation maintenance the situation is the same, for 2 days there was a heavy gas odor in the area, and there is a picture taken in the evening where we can see the gas cloud just minutes before the explosion, as having experience in refineries and petrochemical installation I ask just one questions, why the gas detectors did not work??? sending the alarm to the operations room???In consequence all this government history is pure fiction.Thanks
Manuel Suarez
The "latest probe", which blames the country's political opposition to Maduro's administration, is believed by many to be just one more government maneuver to squelch opponents. Some facts to support this notion:1) Refinery workers have indicated that many safety systems were either inoperative or non-existent altogether (e.g. gas detection and alarm systems) largely pointing to incompetence and/or negligence as the main causes of the explosion.2) The Maduro administration has refused to make public the countries, companies and experts that produced the alleged "latest investigation"2) PDVSA failed to report the claim to the insurance company providing coverage for Amuay's facilities. The reason is believed to be PDVSA's fear of an insurance audit and investigation into the operating and maintenance practices at the refinery.PDVSA is also not renewing its current insurance and is very rapidly changing insurance brokers from the current one, with many years of experience, to a little known Russian outfit.

No report, no probes, no investigation comittee but here the conclusion: Sabotage.

D2 unattended to display stream - suggestions please
January 26, 2012, 08:16:55 AM »
Greetings all,
I am considering the D2 for use as a client to receive video streams sent over the lan but I need guidance in selecting the software and configuration. Point me in the right direction and I will take things as far as I can before asking more questions. This idea is just that - an idea. I don't know that it will be possible, practical, or most important, reliable. I also can't afford to waste much time on false starts. Thus, my questions.
I am wanting the D2 to power up (preferably black screen or minimal blinking cursor) uoon application of power. On completion of boot, be listening for some kind of broadcast or stream. When a stream appears, put it on the display in full screen. When the stream stops, back to black. I plan on sending streams only at the native resolution of the display, progressive only and either 24, 30 or 60 FPS. The ultimate requirement is 1080P 60 FPS with support for 24 FPS as well. Conversions to these rates will be handled by the source server. The streams will have a live component so there should be no buffering to speak of and delays from conversion and processing need to be minimized (none in the D2). There will probably be no audio in the stream (there may be later if we add more of these clients). The number of these clients will be 2 or 3 on a private subnet running at 1G to start. There will be more bells and whistles I would like to have but that is the essential requirement.
The assumption is that I will be generating stream(s) from a Windows workstation using an app that can do that. A rather large assumption, I know... I have intentionally not specified protocols (mpeg, etc) since at this point I don't care. Whatever will work we will use. We need to get 1080P60 and will use whatever gets us that. Other assumptions - that a broadcast on a private subnet with no packet loss, etc. to identical devices with identical software (of course IP and MAC addr, etc will differ) will produce video on displays that is very close to perfectly in sync, and separate but identical streams will also be nearly in sync. In the separate but equal scenario, any packet loss might accumulate which could be a problem.
Bells and whistles later may include:
Webmin administration (this will probably be installed at start).
A default slide show running on a schedule. Streams will override of course.
Slides may be on D2 or on local server (but possibly outside private subnet).
NTP client to keep clocks in sync.
Ability to stream unique content to each D2 as desired.
Stuff I haven't thought of yet.
VLC might do what I want but there may be something better simpler or...
Thanks to all for your time.

I think gstreamer is better
due to at d2plug has hardware accerlate at gst framework, so I think gst is better
but I don't have any experence at your implement function so I just think if you could used gst is beeter ,others I don't have any idea

Is the Rudin-Keisler order of ultrafilters linear?
Is it a well ordering?
Is the Rudin-Keisler order of ultrafilters linear?
Is it a well ordering?
This would be more suitable as a comment, but I do not have enough reputation points. Among the first results that google spits out for Rudin Keisler is the paper Anatoly Gryzlov: On the Rudin-Keisler order on ultrafilters; http://dx.doi.org/10.1016/S0166-8641(96)00109-5 It claims that there are incomparable ultrafilters (with respect to R-K order) and provides several further references.
As Martin Sleziak already pointed out, there are Rudin-Keisler incomparable ultrafilters on $\omega$ (while Joel is talking about ultrafilters on a measurable cardinal). This is provable in ZFC.
Andreas Blass showed that under Martin's Axiom, there are actually $2^{\mathfrak c}$ pairwise R-K incomparable ultrafilters, i.e., as many as you could possibly have.
Here $\mathfrak c$ is $2^{\aleph_0}$.
He also showed that the real line can be embedded into the R-K order of ultrafilters on $\omega$ (this again assumes Martin's Axiom).
One often considers the Rudin-Keisler order in the large cardinal context of a measurable cardinal $\kappa$, where one considers only $\kappa$-complete nonprincipal ultrafilters on $\kappa$. So let me provide the answer for this context, which is that it is independent of ZFC whether the Rudin-Keisler order on such ultrafilters is linearly ordered.
Two ultrafilters are Rudin-Keisler equivalent if and only if they are isomorphic, if and only if they give rise to the same ultrapower embedding of the universe (I believe this was a topic of some of your previous MO questions). One ultrafilter $\mu$ is RK-below another $\nu$ if and only if the ultrapower $j_\nu$ by $\nu$ can be factored as $j_\nu=h\circ j_\mu$ for some elementary embedding $h:M_\mu\to M_\nu$. It follows that the Rudin-Keisler minimal ultrafilters are precisely the normal measures.
On the one hand, in the canonical inner model $L[\mu]$ having one measurable cardinal $\kappa$, it turns out that every ultrapower embedding by a $\kappa$-complete ultrafilter on $\kappa$ is equivalent to a finite iteration of $\mu$. That is, every $\kappa$-complete nonprincipal ultrafilter is Rudin-Keisler equivalent to a finite product $\mu^n$ of $\mu$ with itself. Such measures form an increasing $\omega$-sequence, and so in this model, the Rudin-Keisler order on measures on $\kappa$ is a linear order isomorphic to $\omega$.
On the other hand, in contrast, one can perform forcing so as to create many normal measures. In such a model, the Rudin-Keisler order cannot be linear, since normal measures, being minimal, are incomparable with respect to the Rudin-Keisler order.
Update. Meanwhile, the Rudin-Keisler order on this collection of ultrafilters is well-founded, which fulfills part of what you had requested. The reason is that we can associate to each $\kappa$-complete ultrafilter $\mu$ on $\kappa$ the least ordinal $\delta$ generating the whole embedding, that is, for which $M_\mu=\{j_\mu(f)(\delta)\mid f:\kappa\to V\}$. It turns out that $\mu\lt_{RK}\nu$ implies $\delta_\mu\lt \delta_\nu$, and so the Rudin-Keisler order is well-founded.

Time magazine (December 16) introduces Mitt Romney's new TV campaign commercial as follows:
"New Mitt NH TV spot hits twin goals: Romney as economic savior and Romney as a man who can relate to working people. Romney: "We've got to get this economy going again. At the foundation of everything good is a very strong economy."
I'm interested in the expression, "At the foundation of everything good is a strong economy. "
Is "At the foundation (base) of everything +adjective is (predicate) a popular idiom, or just a set of words?
Can I say conversely "At the foundation of everything bad is a very bad economy (management, waste of money, a person, e.g. you, president of a company) without being felt awkward?

Is there a way to revert to the default icons for gmail / market / contacts and the like ?
Are icon sets a system wide setting ? Or are those sets specific to the software application which displays them.

I am confused regarding supermanifolds. Suppose I consider R^(1,2) (1 "bosonic", 2 "fermionic"), This map (x,a,b) -> (x+ab, a,b) (a,b are fermionic) is supposed to be a morphism of this supermanifold. But I thought a morphism should be a continuous map from R->R together with a sheaf map of the sheaf of supercommutative algebra of smooth functions. How is this (x-> x+ab) giving me a continuous map from R->R?
The ring of functions on your supermanifold is $C^\infty(\mathbb{R}) \otimes \mathbb{C}[a,b]$, where $a$ and $b$ are odd. The even part is then $C^\infty(\mathbb{R}) \oplus C^\infty(\mathbb{R})ab$, where $(ab)^2 = 0$, so there is an even nilpotent direction. You might want to view it as a thickening in a perpendicular direction. The map in question is the identity on the reduced quotient $C^\infty(\mathbb{R})$, and this yields the identity map of manifolds (which is continuous). The $(x \mapsto x+ab)$ can be viewed as an infinitesimal shearing on the even part.
Unlike many schemes, but similar to ordinary manifolds, a map of super-manifolds $$(X, \mathcal{O}_X) \to (Y, \mathcal{O}_Y)$$ determines and is completely determined by the map of superalgebras obtained by looking at global sections: $$\mathcal{O}_Y(Y) \to \mathcal{O}_X(X)$$ In the example at hand this is the graded ring map: $$ x \mapsto x' + a'b'$$ $$ a \mapsto a'$$ $$ b \mapsto b'$$
This map induces a map of rings after we mod out by nilpotents: $$C^\infty(Y) = \mathcal{O}_Y/Nil \to \mathcal{O}_X / Nil = C^\infty(X)$$ This map in turn induces a smooth map $X \to Y$ (in fact it is equivalent to such a map). In this case, after modding out by nilpotents we get the map $x \mapsto x'$, i.e. the identity on the underlying manifold $\mathbb{R}$.
A morphism of supermanifolds is a continuous map and a map of sheaves of superfunctions in the opposite direction. What you've given is the second part of the datum. In your example, I guess the continuous map $\mathbb R\to\mathbb R$ between the underlaying manifolds is just the identity.

Toast to TLC
THE PARTY After having helped some 16,000 children with serious illnesses and their families for 30 years, HUGS brought together its friends and supporters for a fun-filled anniversary celebration at The Kahala Hotel and Resort. THE HIGHLIGHTS Over sparkling cocktails, local personalities, top doctors and community supporters mixed and mingled before heading to their tables. With television presenter Dan Cooke as emcee, the gala was a heartwarming affair, including a crowd-pleasing performance by 'ukulele virtuoso Jake Shimabukuro. (Fans in the audience couldn't help but capture the moment on their iPhones.) But some attendees were even more excited by the prospect of what was to come during the coveted live auction. The evening's spectacular items included a jaunt to Lāna'i for friends on a private jet, a six-day getaway to Lake Tahoe, and a private luncheon for a winner and 39 friends on a secret island. THE PLAYERS HUGS CEO Robin Johnson; musician Shimabukuro; Hawaii News Now's Dan Cooke and Steve Uyehara; Darrell and Cathy Lee; Wenli Lin; Chason Ishii and leading island doctors, including Dr. Elizabeth Ignacio, Dr. Lauren Dawson and Dr. Jeffrey Yeoh.

I have founds lots of DON'Ts with Google but so far, no simple resource that would explain to someone like me who knows that he is not smart enough get this right without help how to use correctly a modern symmetric block cipher.
I plan to use this to exchange a bunch of control messages over a connection-less datagram-oriented transport protocol. I plan to distribute some initial secrets over SSH-tunneled http connections and then the remaining secrets will be spread over the network through the already-secure channels. It is thus important to me to try to keep the secret as small as possible in size to fit as many of them as possible within a single datagram.
To summarize, what cipher should I pick, how should I setup the IVs, the MACs, etc. Alternatively, a hint on resources that could give me enough background to make these decisions myself would be fine but I am still struggling to find something that it somewhat more practical than crypto textbooks.

(Berger, 1958) Let M be a closed n-manifold with sec ≥ 1 and injp > π/2 for some p ∈ M, then M is (n − 1)-connected and hence a homotopy sphere. I don't quite understand the "hence".Must a n-1 connected manifold be a homotopy sphere? After we get M is n-1 connected,how can we prove M is a homotopy sphere?
By Hurewicz (n-1)-connected implies vanishing of the first n-1 homology groups. Since the manifold is closed and (by simple connectedness) also orientable, we have H_n=Z. Of course the higher homology groups vanish. Thus the manifold is a simply connected homology sphere, hence by Hurewicz' converse a homotopy sphere.

Some loyal Times readers have told me they have little interest in commercial real estate, my beat since 2003. I write mainly for the Square Feet column that runs in the Business section on Wednesdays.
But maybe they do care about how neighborhoods evolve, how tax dollars are used to subsidize shopping centers or how sprawling cities are beginning to go vertical. What about the wheeler-dealer who took 10 days to buy $7 billion worth of Manhattan office buildings and then lost them the following year? Or the big business of housing your elderly parents, your college-age children and your son or daughter in military service?
And as the world reels from a mortgage fiasco that has caused the worst financial crisis in decades, the once-flush commercial real estate industry is starved for cash and bracing for a calamitous fall that is likely to continue even after the economy recovers. Those subjects are all part of my beat.
A native New Yorker, I joined The New York Times in 1995 after 13 years at The Los Angeles Times, where one of my beats was Hollywood. Covering the movie industry catapulted me into a world of risk-takers and dreamers — good preparation for what I cover today.

Despite the mean-spirited prank, Groeninger, apparently "in love" with Rivera, said yes. Later, on Twitter, Rivera compared his proposal to taking a dump:

Know Your Rights
Your Speech Rights
Knowing what you can and can't say can be a little confusing sometimes. But if you attend a public school, your right to express yourself is protected by the constitution under the First Amendment.
LGBTQ students and allies have a constitutional right to promote awareness and fairness.
There are a few situations in which student speech may be restricted—within reason.
Student speech rights in private schools may be subject to different restrictions.
Schools should grant these communications privileges fairly.
As one federal appeals court put it: "There is no constitutional right to be a bully."

When you buy resources from neighbor do you take the card or just get access to the resources you need?
Sign up
- Anybody can ask a question
- Anybody can answer
- The best answers are voted up and rise to the top
No, you do not take the card. The neighbor retains the card; you are simply allowed to use your neighbor's cards, for a fee of course.
You can also buy the resource from the top corner of the civilization cards as well. It doesn't need to be a "card".
Just the resources.
The rules on page 4 define things pretty well.
Cards are called "structures", the brown ones can generate "resources"
In red, there is a notice:
Obviously if you were to take the card, the production of the city would be reduced and this is prohibited.

I replaced my iPhone 4 today and used iTunes to restore all of my settings, contacts, calendars and apps. Everything but my music was restored- including my purchased items. I have tried the iTunes Store on iTunes and on my iPhone and I feel like I'm missing something- is there another step that I should be taking when restoring to retrieve my music?
It appears there are multiple ways. The first, is outlined by Apple here.
Automatic Downloads and downloading previous purchases are not compatible with iPhone 4 (CDMA Model). Automatic Downloads and downloading past purchased music and TV Shows is supported only in the US and is not compatible with iPhone 4 (CDMA Model). Previous purchases may be unavailable if they are no longer on the iTunes Store. Downloading past purchased TV Shows requires iTunes 10.4 or later.
It details the following methods:
Note: To download all songs from a purchased album, tap on the Album's toggle button to switch to Album view.
Once you redownload the music to your phone, they will transfer to your iTunes library when you sync the device.
And an alternate method using the new iCloud service can be found here (it's of note that when I tested this method, I could redownload books and apps but not music; your experience may, however, differ).
If you have back up your music, you can restore from the backup.
To restore information from a backup, use one of the following methods after connecting your iOS device to the computer with which you normally sync:
Solution from Apple.com: ht1766
Try enabling "manually manage music", and then dragging the music you want onto your iPhone from iTunes.
If you're outside of the U.S. you'll be missing out on the iCloud previous purchases fun at the moment, it is coming but no one knows when.
However, if you get in touch with Apple through iTunes support they can restore your purchases so they're redownloadable, it's accepted that they'll do it once for you and never again but that's probably your best option.
If you don't have a backup, the following user tip is worth checking through:

Vaginal Dilators After Radiation Therapy - Are They Necessary
The Abramson Cancer Center of the University of Pennsylvania
Last Modified: January 26, 2012
My mother is a 70 year old widow who had endometrial cancer and had radiation. Now she is being told to use a dilator, but she is uncomfortable doing this. Is it really necessary?
Nicole Ross, RN, MSN, OCN - Radiation Oncology Nurse at Penn Medicine, responds:
It is recommended that all female patients who receive radiation to the pelvis use a vaginal dilator a few times per week for life. This is used to prevent vaginal stenosis (narrowing and stiffening) or adhesions (scar tissue that can close off the vagina) forming in the vagina. If she is not sexually active and does not use a dilator, it potentially could make GYN exams uncomfortable for her. I understand that she may feel uncomfortable and it is very personal. If she chooses not to, she should inform her radiation oncologist.
You can learn more about vaginal dilators after radiation on OncoLink.

A graceful expression of refined, powerful sound.
Find store
BeoLab 20's powerful and refined performance comes from the active speaker design and the uncompromising engineering of its digital sound engine. The conical shape of the speaker embraces every nuance, clearly reflecting Bang & Olufsen's eye for form and function.
BeoLab 20 offers Immaculate Wireless Sound for crystal clear, wireless bliss, giving you the freedom to decorate your room as you like – and place BeoLab 20 exactly where you want.
The crowning glory of BeoLab 20 is the Acoustic Lens. Its 180-degree horizontal dispersion conveys smooth high-frequency sound evenly throughout the room.
The Acoustic Lens maximizes the area of optimum sound in front of the speaker, enabling the listener to move around more freely while still experiencing perfect sound. The technology also minimizes the effect of floor and ceiling reflections, reducing unwanted distortion, thereby improving the overall sound experience.
Discover the improved sense of space and realism that the Acoustic Lens brings to the soundscape – conveying every little detail and nuance in a perfectly balanced, natural manner.
Fitted inside BeoLab 20's 18 litre enclosure, the woofer's two, 160 Watt Class D amplifiers and generous 10" unit guarantee precise and powerful low frequencies.
To deliver ultra-high-intensity bass without risking woofer damage when playing at full volume, Bang & Olufsen's Adaptive Bass Linearisation constantly monitors and adapts the lows. For maximum placement flexibility, the speaker can be optimised to its immediate surroundings via a manual position switch, activating Bang & Olufsen's innovative room adaptation technology.
BeoLab 20's pitch perfect performance comes from the careful calibration of its digital engine, courtesy of Bang & Olufsen's Tonmeister, Geoff Martin.
At Bang & Olufsen, Tonmeister Geoff Martin cautiously tuned and tweaked every nuance of BeoLab 20. According to Geoff Martin, the secret to delivering its natural, refined sound, comes from listening – pure and simple:
"Rather than building a tuning based on a prediction, we experience it instead – by playing the loudspeaker in different rooms and different positions and creating some sort of accustomed behaviour in the real world."
All of BeoLab 20 is minutely designed down to the last detail, including
the sophisticated technology within.
The significant processing power of BeoLab 20's digital audio engine is the key to its superior sound.
Digital technology has allowed our engineers to dramatically improve the speaker's acoustic performance by meticulously tweaking each driver's equalization. Every single parameter of sound has been analysed by Bang & Olufsen's sound designers to provide the finest soundscape possible.
The result is a digital engine with vast amounts of processing power, intelligently utilizing every single watt to its fullest potential.
BeoLab 20 supports Immaculate Wireless Sound – Bang & Olufsen's concept for crystal clear, wireless sound.
BeoLab 20 is based on WiSA technology operating in the uncongested part of the 5 GHz frequency band. It offers crystal clear wireless sound with unprecedented quality and robustness, and significantly reduces cable clutter – only a single power cord for each speaker is needed.
BeoLab 20 connects seamlessly to all Bang & Olufsen products with Immaculate Wireless Sound, and all other WiSA-compliant products.
Discover Immaculate Wireless Sound
BeoLab 20's combined 640 watts come alive through its active speaker design, resulting in power output that goes far beyond mere wattage.
This is due to the greater potential for control and optimization that an active speaker design provides.
Active speakers are a Bang & Olufsen hallmark which allows us a high degree of design freedom, because the cabinet size can be reduced significantly compared to more conventional passive constructions. The acoustic power derived from such a small volume is simply stunning.
In an active speaker, each driver unit (i.e. woofer, tweeter) has its own dedicated amplifier and DSP channel, allowing us to optimise the tonal balance and reduce distortion in a very robust design. This is accomplished using ideal crossover networks and individualised corrective filtering, granting us vast amounts of control over the loudspeaker's performance.
Powerful laser technology, precision milling and a specially developed composite make the Bang & Olufsen logo shine through the aluminium.
The logo glows pleasantly at night when BeoLab 20 is turned on and stands proud as always when the product is turned off, ensuring that this beacon of quality is always visible.
BeoLab 20's superior sound reflects the vision of its designer, Torsten Valeur.
From the iconic Acoustic Lens right down to the base of the conically shaped cabinet, BeoLab 20 seamlessly merges form and function.
Everything underlines its purpose. The cooling grill's soft-touch lacquer calmly hints at its role. The Acoustic Lens' pearl-blasted base gently contrasts the high-gloss aluminium of the lens itself – highlighting the unit's importance in spreading great sound throughout the room.
As a final touch, the cleverly designed base of the cabinet lends a subtle, floating expression to the speaker.
Complete BeoVision Avant's cinematic experience with the stunning sound of BeoLab 20.
The ultimate TV deserves to be accompanied by the finest audio. Unleash the full force of BeoVision Avant with a BeoLab 20 surround sound setup and immerse yourself in a cinematic journey.
BeoVision Avant already features powerful centre speakers. Therefore, giving BeoVision Avant centre stage supported by four BeoLab 20s provides a truly breathtaking surround experience.

My Hand-drawns. (Firsts) - 09-03-2008, 07:50 PM
Base: Umm...I forgot the site.
Ok, So I forgot to shade the hair, and I believe I shaded along the base, but I'm not all that sure <_< Since I'm quite tired, and my brain is like...blah, this doll isn't quite perfect, and it wasn't my first, yet I'm still new to this...um...yeah. I personally think her legs look like a tigress, even though it's supposed to be a dress, and she's egyptian. The blue dots in her hair are supposed to be beads, since ancient egyptians sometimes put beads in their hair. I like her a lot though, mostly because she turned out better than I had hoped, and she was my first profile doll. I was going to do her as Queen Nefertiti, but that didn't work out(don't ask) So, yeah xD She's much better than my past dolls, yet I don't really want to post them. Please tell me what you think of her :]
"Are you my mummy?" "Don't blink." "Count the shadows." "Look behind you."
