The present disclosure is generally related to a system to detect poor process ground connections, and more particularly but not by limitation to systems to detect poor ground connections within industrial process monitoring field devices, such as magnetic flow meters.
Field devices are used in industrial process monitoring and/or control systems to monitor process parameters associated with a particular process. Such process parameters can include fluid pressure, fluid flow rate, fluid temperature, other process variables, or any combination thereof.
Magnetic flow meters are a type of field device that is used to measure a fluid flow rate of a conductive process fluid as it flows within a flow tube that is coupled to a pipe. A particular magnetic flow meter includes an electromagnet and electrodes. In accordance with Faraday's law of electromagnetic induction, the electromagnet is used apply a magnetic field to the process fluid within the flow tube to induce an electromotive force (EMF) in the process fluid, which EMF is proportional to the flow rate. The electrodes are positioned in the flow tube to make electrical contact with the flowing process fluid to sense the EMF. In a particular embodiment, the EMF is measured by the flow meter using an amplifier connected across the electrodes to amplify the EMF signal and using an analog-to-digital converter (ADC) to quantize the output of the amplifier to produce a data value related to the fluid flow rate. In a particular example, the EMF is measured relative to a signal ground, which may be tied to the process fluid. The electrical potential of the process fluid can be used as a reference, which may not necessarily represent an Earth ground connection.
The magnetic flow meter and associated transmitter circuitry are referenced to the process to provide a stable reading. This process or ground connection is established via an electrical connection between the flow tube and the process. The ground connection can be established using ground rings, which strap to the flow tube, a ground electrode which is connected directly to the flow tube, a strap between the flow tube and the adjacent conductive pipe, another ground connection, or any combination thereof. In a particular embodiment, earth ground can provide a low noise reference and often is required by electrical safety code. However, poor ground connections can lead to erroneous process measurements.
In a particular embodiment, a field device is disclosed that includes a pair of electrodes coupled to a process fluid and a diagnostic circuit coupled to the pair of electrodes to monitor a common mode signal. The diagnostic circuit is adapted to detect a poor ground connection associated with at least one electrode of the pair of electrodes based on line noise associated with the common mode signal.
In another particular embodiment, a magnetic flow meter is disclosed for measuring a flow rate of a fluid in a pipe. The magnetic flow meter includes a flow tube adapted to couple to a pipe to carry a fluid, a magnetic coil disposed adjacent to the flow tube to induce an electromagnetic force (EMF) within the fluid, and at least two electrodes disposed within the pipe, the at least two electrodes being electrically isolated from the flow tube and from one another. The magnetic flow meter further includes measurement circuitry coupled to the at least two electrodes and adapted to measure flow rate based on the induced EMF and includes diagnostic circuitry coupled to the at least two electrodes to monitor a common mode signal. The diagnostic circuitry is adapted to detect a poor electrical ground connection when line noise associated with the common mode signal exceeds a noise threshold.
Magnetic flow meters and other field device utilize a ground connection to the conductive process fluid to provide for accurate process measurements. If a proper ground connection is not present, the differential voltage signal sensed at electrodes of the magnetic flow meter, for example, may experience line noise, such as noise signals within a frequency range of approximately 50 to 60 Hz, from the surrounding process environment. Such differential noise signals can interfere with the flow rate measurement resulting in large measurement variability. In a particular embodiment, the differential voltage can be determined according to the following equation:
V Diff =V 1 +V Noise1−(V 2 +V Noise2) (Equation 1)
If a difference between the noise voltage signals (VNoise1 and VNoise2) is greater than a diagnostic noise threshold or limit, diagnostic circuitry is provided that is adapted to generate an alert relating to a ground/wiring fault.
In addition, a poor process ground connection can lead to common mode voltage line noise that interferes with the electrode voltage signal. In a particular embodiment, the common mode voltage line noise is prevalent in a frequency range from approximately 50 to 60 Hz. It should be understood that the line noise may be influenced by ambient process noise and vibrations, by nearby radio frequency signals, by other sources of noise, or any combination thereof. The common mode line noise can adversely impact amplification circuitry, for example, by causing amplifiers associated with the field device to enter a saturation condition if the common mode voltage portion of the electrode voltage signal exceeds current limits. In a magnetic flow meter, the saturation point can be the upper and lower limits of first and second voltages (V1 and V2) associated with the respective electrodes. The saturation point can be determined according to the following equation:
V Sat =V 1 +V Noise1 (Equation 2)
V Sat =V 2 +V Noise2 (Equation 3)
Amplifier saturation tends to distort the differential measurements to a lower value, which can limit differential line noise detected by the transmitter to the point that existing line noise diagnostics do not report ground/wiring fault conditions. Unfortunately, if the differential measurements are reduced, the differential mode line noise may be insufficient for detection of a poor electrical ground connection.
In a particular embodiment, a magnetic flow meter is provided that includes diagnostic circuitry coupled to electrodes within a flow tube of the magnetic flow meter. The diagnostic circuitry is adapted to examine the line noise amplitude of the common mode electrode signal (and optionally the differential mode electrode signal) to detect a poor or poor ground connection. By examining the common mode voltage line noise, a poor electrical ground connection can be detected even when the differential mode electrode signal is relatively small (not large enough to detect a poor electrical ground connection).
In a particular example, the diagnostic circuitry is adapted to monitor line noise associated with the common mode electrode voltage in addition to the differential line noise. In a particular embodiment, the common mode line noise provides a better indication of the presence of a poor or poor process ground connection. In some instances, there may be sufficient common mode line noise to saturate the amplifiers, but very little differential line noise may be present.
The magnetic flow meter 100 includes a flow tube 124 that has an insulated tube or liner 126 adapted to carry a flowing liquid 128 that is coupled to an electrical ground 130. The coupling of the liquid 128 to ground is usually completed by way of contact between the liquid 128 and a metal pipe that is attached to the flow tube 124. The flow tube 124 includes an electromagnet 132. The electromagnet 132 includes coils 134 and a magnetic return path or core, illustrated schematically at 136. Further, the flow tube 124 includes first and second electrodes 138 and 140 and electrode leads 142 and 144, which form an electrode circuit 146.
In a particular embodiment, the electrode circuit 146 can also include first and second amplifiers 148 and 150. In a particular example, the first and second amplifiers 148 and 150 are unity gain buffers (sometimes referred to as impedance converters) that have extremely high impedance, low leakage inputs and low impedance outputs. The first and second amplifiers 148 and 150 replicate the electrode voltages from the electrodes 138 and 140 at the corresponding amplifier outputs and isolate the electrodes 138 and 140 from the loads connected to the outputs of the first and second amplifiers 148 and 150. The first and second amplifiers 148 and 150 may be coupled to the flow tube 124 or disposed within a housing associated with the magnetic flow meter 100, depending on the particular implementation.
The diagnostic circuit 122 includes an analog-to-digital converter (ADC) 160 coupled to the electrode circuit 146 via the first and second amplifiers 148 and 150 and to the electrical ground 130. The ADC 160 is adapted to generate an output signal related to the outputs of the first and second amplifier 148 and to provide the output signal a processor system 156, which is coupled to a coil driver 151 and to outputs 152 and 154, which may be coupled to loop wiring to receive power and to communicate data. The coil driver 151 can be controlled by the processor system 156 to apply a signal to the coils 134. In a particular embodiment, the coil driver 151 applies an approximately square wave drive or excitation current to the electromagnet 132, and the corresponding electrode potentials are also approximately square waves, including "flat" time intervals when the flow induced EMF is flat or stable. In this example, the diagnostic potentials can be sampled by the ADC 160 during the time intervals when the flow-induced EMF is flat or stable.
The processor system 156 includes a memory 162 and a processor 164 having access to the memory. The memory 162 is adapted to store a diagnostic algorithm 166 that is executable by the processor 164 to diagnose electrode leakage, which may be related to process fluid leaking past a damaged seal or related to another source, based on the output of the ADC 160. Further, the memory 162 stores a saturation detection algorithm 168 that is executable by the processor 164 to monitor a common mode signal and a differential mode signal related to the electrodes 138 and 140 at particular frequencies to detect line noise associated with a poor connection to the electrical ground 130. In a particular embodiment, the poor connection may result from a loose wire, corrosion, improper installation, or any combination thereof. In a particular embodiment, the saturation detection algorithm 168 can detect saturation of the first and second amplifiers 148 and 150 to infer a faulty connection to the electrical ground 130. In a particular example, the saturation detection algorithm 168 is adapted to monitor a common mode voltage line noise associated with the electrodes 138 and 140, which noise is prevalent in a frequency range from approximately 50 to 60 Hz.
In a particular embodiment, the processor system 156 is adapted to generate a first diagnostic output related to electrode leakage (i.e., process fluid in contact with circuitry associated with the flow meter 100) and/or to generate a second diagnostic output related to a poor or faulty connection to the electrical ground 130. In a particular embodiment, electrical potentials between the outputs of the amplifiers 148 and 150 require a liquid ground reference. In a particular embodiment, if the ground connection is poorly centered or balanced relative to the electrode potentials, then the processor 164 can use the diagnostic algorithm 166 to infer electrode leakage. However, if the electrical ground 130 connection is poor or faulty, common mode line noise can drive the first and second amplifiers 148 and 150 into saturation, which saturation can be detected by the processor 164 using the saturation detection algorithm 168.
In a particular example, when the electrode circuit 146 is free of leakage, it is found that the flow-induced EMF on each electrode relative to the electrical ground (diagnostic potentials) tends to be balanced or equal, but of opposite polarity. Accordingly, when they are added together, the result tends to be near zero under normal operating conditions without leakage. However, if the connection to electrical ground 130 is faulty, even if the EMF remains balanced, the common mode line noise can drive the amplifiers 148 and 150 into saturation. Thus, the saturation detection algorithm 168 that is executed by the processor 164 can be used to diagnose poor electrical ground connections, even when the flow meter 100 may appear to be operating correctly.
In a particular embodiment, the outputs 152 and 154 will carry a 4-20 mA analog loop signal, and the diagnostic output at the output terminal 154 can be a HART protocol signal superimposed on the 4-20 mA analog loop signal. In another particular embodiment, the outputs 152 and 154 can be loop wires that carry a different protocol signal. In still another embodiment, the outputs 152 and 154 can be coupled to a wireless transceiver to send information to and receive information from a control system.
The transmitter device 204 includes an interface 208 coupled to the wiring 206. The interface 208 is coupled to a processor 210 to communicate received data. The processor 210 is coupled to a memory 212, which includes instructions executable by the processor 210 to detect a poor electrical ground connection. In a particular example, the memory 212 includes an electrode leakage diagnostics module 214 that is executable by the processor 210 to detect electrode leakage (process fluid leakage) based on detected voltage potentials associated with the electrode circuit 146. Additionally, the memory 212 includes a saturation/common mode noise detection diagnostics module 216 that is executable by the processor 210 to detect saturation of amplifiers within the magnetic flow meter 202 to infer line noise indicative of a poor electrical ground connection. Further, the saturation/common mode noise detection diagnostics module 216 is adapted to monitor the common mode line noise and to compare it to a noise threshold to detect a poor electrical ground connection. Further, the memory 212 includes a diagnostic control logic module 218 that is executable by the processor 210 to generate an alert based on the determinations made using the electrode leakage diagnostics module 214 and the saturation/common mode noise detection diagnostics logic 216. The alert may be communicated to a display interface or to a control system (not shown). Alternatively, the transmitter device 204 can be a control system and the magnetic flow meter 202 may be adapted to communicate raw measurement data to the control device via the wiring 206.
The flow meter 202 includes electrical interconnects and magnetic coils (shown in
The flow meter 202 further includes a housing 228 to house circuitry associated with the flow meter 202 and includes a flow tube 232. In a particular embodiment, the flow tube 232 can include an access panel 230 to permit operator access to electrode wiring within the flow tube 232.
Depending on the implementation, the flow tube 232 may be electrically grounded to the pipe 224. Alternatively, the flow tube 232 may provide a process ground connection that may or may not correspond to an earth ground-type of connection. In a particular example, the flow meter 202 is adapted to monitor a process fluid that is flowing within the pipe 224 and through the flow tube 232 based on Faraday's law of magnetic induction. Raw data associated with the flow measurements can be communicated to the transmitter device 204 via the wiring 206. The processor 210 of the transmitter device 204 is adapted to access the saturation detection diagnostics module 216
Additionally, though the flow meter assembly 300 is shown with flange elements 320, other connection structures may be used. In an alternative embodiment, the flow tube section 302 can be formed without flanges, and the flow meter assembly 300 can be clamped between flanges of mating pipes using extended bolts to cage the flow meter assembly 300. The flow meter assembly 300 includes transmitter circuitry 312, which includes electrode circuitry 314 and diagnostic circuitry (such as the diagnostic circuitry 122 illustrated in
In a particular embodiment, the magnetic coils 316 and 318 are excited to generate a magnetic field, which induces a voltage in the process fluid flow within the flow tube section 302. Process monitoring circuitry, such as the electrode circuitry with the transmitter housing 328, measures the voltage potential between the two electrodes 308 and 310, which can be used to determine a rate of fluid flow. Specifically, the magnitude of the induced voltage (E) is directly proportional to the velocity of the conducting fluid (V), the conductor width (W), and the strength of the magnetic field (B) according to the following equation: E=kBWV, where the variable (k) represents a constant. The magnetic field coils 316 and 318 are generally positioned on opposing sides of the flow tube section 302 to generate and apply the magnetic field. Since the width (W) is the spacing between the electrodes and the magnetic field (B) is controlled by the magnetic coils 316 and 318, the only variable is the velocity (V) of the process fluid. The liner 306 (or an insulating element) prevents the voltage signal from shorting to the pipe wall. Thus, the output voltage (E) is directly proportional to the liquid velocity, resulting in an inherently linear output. This output voltage (E) may also be referred to as an "electromotive force" (EMF), a "flow signal", a "potential" or an "electrode voltage".
As the conductive process fluid moves through the induced magnetic field with average velocity (V), the circuitry within the transmitter housing 328 measures the voltage potential across electrodes 308 and 310. Further, the circuitry within the transmitter housing 328 can monitor common mode and/or differential mode line noise to detect a poor electrical ground connection. In a particular embodiment, the circuitry within the transmitter housing 328 can execute a diagnostic procedure when the pipe is empty to detect a poor ground connection based on line noise, which noise may drive amplifiers associated with the circuitry within the transmitter housing 328 into saturation. Such saturation may be indicative of a faulty ground connection. It should be understood that electrodes 308 and 310 contact the fluid in the passage 304 (when liquid is present), and the fluid completes a circuit between the electrodes 308 and 310. When fluid is not present, the electrodes 308 and 310 represent an open circuit. Nevertheless, line noise may be present if the electrical ground connection is faulty. In another particular embodiment, the circuitry can execute the diagnostic procedure during operation to detect a poor electrical ground connection based on common mode line noise. Further, the diagnostic procedure can include measuring differential mode line noise to infer which conductor may have the poor electrical ground connection.
In a particular embodiment, the circuitry within the housing 328 is adapted to detect a poor electrical ground connection by monitoring common mode line noise within a selected frequency range. In a particular example, the selected frequency range is from approximately 50 Hz to 60 Hz. In another particular example, the selected frequency range can be configured via commands from a host system or by a user via a user input interface to define a frequency range according to the particular implementation. For example, a particular process environment may include process noise that is within a particular frequency range, and the circuitry may be tuned (configured) to monitor such noise within the particular frequency range to detect the poor electrical ground connection.
In general, the common mode line noise is demonstrated by the irregularity of the signal at 404 and 406. Common mode line noise detection circuitry is adapted to detect such irregularities to diagnose a poor electrical ground connection. A poor electrical ground connection can represent a corroded ground connection, a disconnected ground connection, another type of wiring problem, or any combination thereof.
In a particular example, the differential line noise from the two electrodes may partially cancel out, reducing the amplitude of the differential mode noise signal. Reduction in the amplitude of the differential mode noise signal can make it difficult to detect line noise due to a poor electrical ground connection based on the differential mode noise signal alone. However, the common mode noise signal (as illustrated in
In conjunction with the systems, field devices, circuitry, and method disclosed above with respect to

I hate to do it, but there's no way I can keep playing this game anymore, thanks to the devs themselves.
Patch 1.13 from months ago changed the matchmaking, enabling some geographical factor that, in simple terms, region-locks people from playing with other players outside of their area. This hasn't been fixed it and probably won't ever.
For players like myself, there's really no way for us to ever play multiplayer online on our own due to patch 1.13. The only viable, sane option is to party up with someone from the States or Europe and letting them find the lobbies. This is not how you treat your fans.
Thanks, devs at Treyarch, for limiting my options and the people I can play with and for overall ruining the gameplay experience for me, for a game that I paid for and loved up until this point.
Ghosts is fast approaching, I can only hope Infinity Ward doesn't make the same awful mistake.
Dunno where you live at, but 90% of the community would lag out playing with you. Ghosts will have dedicated servers, hopefully the matchmaking will be better for you
Lagging hasn't stopped me from winning games and destroying the competition. If I can do that, they should too. Besides, 90% of the players you're referring to also have a 1-2 second lead advantage on me. I can still win. MW3 plays just fine, so does the first Black Ops. Heck, I can even find games in CoD4 much faster than in BO2. In fact, there are NO games available to me on BO2 now thanks to that patch months ago. There's a 1/100 chance I actually manage to find a match in BO2, and I always have a 1-bar in it. Contrast that with what it used to be prior to 1.13 and I could find matches in moments, with far more favorable connectivity. 3arc just likes to take things that are stable and run it into the ground.
Im in England but seem to be locked to playing with people in Fance, Germany and Spain since 1.13 or maby even before that I have never even played with any Americans and maby 2 or 3 times in a 10 hour game session find some Brit's.
On the plus side I have been picking up 3 new languages probably not the nice words though lol
I have Ghosts on pre-order for PS4 but if that's more of the same I may start playing somthing else like Battlefield or Killzone because it's just no fun when I don't even know what my team are saying.
Hi Secondbanana,
Thanks for posting. Can you please clarify the issue you are having? Are you not able to locate a match at all or do you find searching for a match takes a bit longer. What region are you in? Do you notice this occurring at certain parts of the day or even weekday/weekend? What do you currently have you search preferences set to? What game mode or playlist do you often play?
PS3 update notes: http://community.callofduty.com/thread/200545668#.UldwWVBebnE
Thanks ^AH
(This response is long, drink some coffee if you dare reading this.)
There's really no help that could be done unless the matchmaking itself is tweaked back to what it was prior to 1.13. I KNOW that the patch made changes to it, and any patches past that point have done nothing to fix or lessen the damage it's done.
The region is Guam, and the entire area has been affected negatively by that patch. (To anybody who lives in the States, don't come in here saying that you can find lobbies in a heartbeat and nothing is wrong - you live in the States. Region is big, there are always players there online all the time.)
Months after it's happened, I'm walking around the mall and I still hear random people complaining about it, wondering why it takes them an approximate 20-30 minutes to find lobbies now when it used to only take a minute or less.
The occurrences are everyday, 24/7. In most of my cases, a lobby is never found, period. That never happened before 1.13 came along. On the rare chance I actually find other players online now (the chances are extremely slim), once the match starts I have a terrible 1-bar connection, just some silly red pillar of uselessness next to my player name. And these are supposed to be players within/close to my region? I really doubt it. My gametype was TDM, and my search preference is always set to "Any." It always worked great for me - I could pick "Find game" and it would up and find a lobby ASAP, within just a moment or so, not a long wait at all.
And then 1.13 came along and now "Any" is useless. Impractical. The wait is so long, I could have found and played a full match of CoD4 while BO2 would still be searching for a lobby.
What irks me the most is that I can party up with a friend who lives in the U.S. - when he finds a game for us, my connection to the match is so much more favorable, it was almost like I was playing on a copy of the game that didn't have 1.13 installed. Mind you, the lobbies he finds for me are also populated with other people from the U.S.
So, ironically, I have a better connection when I'm playing with and against players from the other side of the globe compared to regions closer to Guam. Patch 1.13, I tell you.
And then once he signs off, I'm back to giving up on the game. I already know I won't find a match if I tried looking for one myself. (and if I do somehow find one, I have a 1-bar. Great.)
For now I just have to forget this game. It was shaping up to be my most favorite out of the series - I was striving to unlock diamond camo for everything, I struggled and plowed through alot of matches to finally reach Master Prestige, and then in the end my whole experience is ruined by a single patch. A season pass seems pointless now when I can't even play the Apocalypse maps online, with players from locations the game won't ever bother trying to match me with anymore.
All I can really do now with this game is play against bots. Sometimes join a zombie invite. As for multiplayer, it's dead to me if I'm not even allowed to go out and play with/against randoms from across the world. It's called "Play Online" for a reason. "Local" has it's own separate place on the MP menu.
"I'm gonna miss you, diamond MTAR."
Here are other links referring to patch 1.13. One of them belongs to myself. (And the second link is me getting very impatient, so sorry about that.)
Re: Difficult to join multiplayer games.
Hi Secondbanana,
Thank you for your reply. The information you provided in your previous post, is that still correct?http://community.activision.com/message/414657373#414657373
If so, the Ping results are are a bit high at 107ms. Can you please provide us with a more current result?
Speedtest.net by Ookla - The Global Broadband Speed Test
Also, is the NAT type that registers in-game still Moderate? If so you may need to establish a static IP address and port forward. Activision Support
Additionally, the available players online at the time you are on will play a factor in the search results. If there are limited players online that are not currently in a match, it may take a bit longer to locate a match.
Thanks ^AH
I hope this reaches you, I had the EXACT same problem. However I am from the States. This is what I did to fix it, maybe it will work for you too. Go into your Game Data Utility on the ps3 XMB, and delete your Black Ops 2 data. Any DLC you had can be redownloaded so don't worry about that. Then I would recommend restarting the ps3 before the loading the game again and downloading the patch you're prompted to install. This should work. I think Treyarch made some error with their patch that messed up the matchmaking when 1.13 overwrote the last updates. Then assuming your matchmaking works like it should, redownload your dlc.

Richmond Public Housing
The Richmond Housing Authority is running a nearly $7 million deficit and owes the feds $2.2 million for past contracting mistakes. The federal government is threatening to take control of the Housing Authority this year if key financial benchmarks are not met.
Geneva Eaton has learned to deal with life in Hacienda: the stench of mold from the stairwell in front of her door, the winter she spent huddled at her stove for heat, the broken security gate that allows drug dealers and squatters to walk past the paid security guards and urinate on her doorstep. But the mice were too much.
For eight months, the 73-year-old woke to handfuls of half-dead mice wriggling in the glue traps lining the floors and cupboard of her apartment. In the space of a few hours, she caught 12. She put her nicest family belongings into storage. She went to bed with the lights on, afraid that the vermin she heard chewing through her walls would bite her in her sleep.
Officials at the Richmond Housing Authority know the Hacienda high-rise, one of its five public housing projects, is infested with mice and roaches. Residents have filed more than 80 complaints about it in the past year, according to agency records. But maintenance workers have done little to fix the problem.

What exact year did "Lady Windermere's Fan" take place?
- print Print
- list Cite
Oscar Wilde's first play, Lady Windermere's fan: A play about a good woman was first staged in London's St. James's theatre in the year 1892. It was published in 1893, and it would be 1 out of 4 major plays produced during a time which is considered to be Wilde's "period of complete success", which ended sadly with Wilde's arrest for gross indecency in 1895.
Lady Windermere's fan tells the story about a 21 year-old young wife who receives, as a birthday gift, a fancy fan from her husband. However, there are rumors that her husband is spending his money on a Mrs. Erlynne who, in the end, is discovered to be a libertine woman, a stalker, a blackmailer and also...Lady Windermere's real mother.
It is interesting to point out the theme of the play because,compared to his other plays, this one is Wilde's least universal. What this means is that the theme of Lady Windermere's fan is somewhat old-fashioned when compared to the flexible themes present in The importance of being Earnest, for example. The enormous changes that Wilde experienced during the early and mid 1890's made him a better writer with each play. Therefore, we can conclude that Lady Windermere's fan was a kind of "experiment" in comedy of manners for Wilde. Certainly one experiment that worked very well for his writing style.


text: Hi Folks, first post............I have a few questions I could use some help on.... I have 160 acres in Montana........keeping up with noxious weeds is a full time process...........I do two kinds of spraying...........one type for my roads and the sides of the roads and the another more time consuming one of spraying everywhere else that noxious weeds pop up............I have in the past used two different type products...........I use Shootout Weed and Grass killer for my roads and then Redeem for the rest of it...........my questions are: 1. The Shootout product so far doesn't seem to bother the trees next to the roads I spray.......I just use 64 oz. for 20 gallons, at a time, in a pull sprayer and spray everything next to the roads............seems to do the job I want without killing the trees.............Question is, is there another product with the 18% Glyphosate that will do the same thing.(without killing the trees)..........The shootout is kinda hard to get.........so any recommendations you folks have would be appreciated..... 2. Redeem is very expensive......is there a cheaper alternative..........???? Thanks in advance and I hope I don't sound to stupid.

Biography of George Rushton
George Rushton. The George Rushton Baking Company, Incorporated, at Rosedale, is the largest concern of its kind in the State of Kansas. Every day its ovens turn out 20,000 loaves of high class bread, sold and consumed principally in the two Kansas cities, while the weekly capacity of the pie plant is 75,000 pies. It is the only pie baking plant on a large scale in the two cities. Baking had been a trade in the Rushton family for so many generations back that no record had been kept of the originator of the business. The president and founder of this business is a master baker in all that phrass implies. His father was a baker before him, and when only eight years of age began learning the business in his father's shop back in England. George Rushton, Sr., was born at Wolverhampton, England, May 18, 1861, the oldest of the thirteen children of George Frederick and Martha Ann Rushton. As member of such a large household and the responsibilities of life being early put upon his shoulders, George Rushton had no opportunities to attend school. He never had a teacher except himself and experience. He learned his A B C's by hard work, and only by much application and diligence did he acquire the fundamentals of a literary knowledge sufficient for business purposes. At the age of eight...Read More

I've been posting about all the problems you may have with scrapbooking that can be solved by using My Digital Studio, and here are a couple more reasons why I love my Digital Studio for travel!
Problem #7
I need a hobby that is portable – I travel a lot for business and have lots of time in the hotel with nothing to do.
Put My Digital Studio on a laptop and GO! Of course, if you use a laptop from work, be sure to ask whether you can add outside software to it.
And if you travel on vacation but have little kids who go to bed early, bring your own laptop from home and scrapbook your vacation pictures at the end of the day, while the little ones are sleeping! That's what I did during my solo trip to Utah for Convention this summer, since it was TOO HOT to be outside in the afternoon… I took a little My Digital Studio break! See my previous post here.

Major hazard reduces to final few batches
Dounreay is within touching distance of completing one of Britain's most important nuclear clean-up tasks.
Staff worked in shifts around the clock during the Christmas and New Year period to keep the destruction of liquid metal from Britain's experimental fast breeder reactor on track.
The contaminated alloy of sodium and potassium was used as coolant in the defunct reactor and its safe destruction is one of the Nuclear Decommissioning Authority's biggest priorities in the UK today.
Its destruction continued around the clock during the holidays, taking the total destroyed to date to more than 161,000 litres.
The site is on course to complete the destruction of the estimated 6300 litres still remaining by the end of March.
The toxic metal is lifted in batches from inside the reactor and its six miles of cooling pipes. The NaK alloy is processed through a purpose-built chemical plant to neutralise the alkalinity and extract the caesium contamination, leaving a salty water that can be discharged safely to sea.
Its rate of destruction means the major radiological and chemical hazard inside the reactor is reducing at a rate of 20 million bequerels a second.
"We're on course to destroy the remaining six tonnes by the end of March and deliver a major clean-up milestone for the Nuclear Decommissioning Authority," said Andy Swan, the engineer in charge of the reactor decommissioning programme at site closure contractor DSRL.
Once the bulk of the metal is destroyed, attention will turn to flushing out and destroying the final eight tonnes of residue from the system.

Live Flu Vaccines Increase Infectious Bacteria Counts 100-Fold in Mice
'If presumably safer "attenuated" flu vaccines are supposed to protect against influenza and its sometimes deadly complications, then why do vaccinated mice have up to 100-fold higher levels of flu-associated pathogenic bacteria than non-vaccinated mice?
A concerning new study published in mBio, an open access journal of the American Society of Microbiology, titled, "Live Attenuated Influenza Vaccine Enhances Colonization of Streptococcus pneumoniae and Staphylococcus aureus in Mice," reveals that live attenuated influenza vaccines (LAIVs) lead to the rapid and sustained overgrowth of pathogenic bacteria in the upper respiratory tract of mice at colonization densities up to 100-fold higher than non-vaccinated mice.'

The Dark Knight Review
Like everyone else in America, I saw The Dark Knight (but not until I had shelled out my $$$ to see The Golden Army the previous weekend). As expected, it was a great movie, but after such blockbuster weekend, my expectations were pretty high. I did not think it lived up the hype – for that kind of jack ($154 million opening weekend), I'm expecting a timeless classic. In reality, I don't believe it is as good as Batman Begins. However, Heath Ledger's performance as The Joker IS timeless. An amazing performance – one that will be forever remembered. It makes Nicholson's Joker in Burton's Batman look like a goofball. This Joker is psychotic, and when he makes you laugh, it is a nervous laughter. You just don't know when he is going to fly off the handle and do something really sinister.
So here are some thoughts on the film:
- When Batman Begins came out, I remember Michael Caine talking about how Nolan convinced him to be a part of the franchise. Caine said that Nolan explained Batman this way: "Superman is the way the United States views itself. Batman is how the U.S. is viewed by the rest of the world." Armed with that information, I couldn't help but notice that The Dark Knight is a true post-9/11 film. It is very politically charged and ties in metaphorically with the U.S.'s current war on terror. I believe the Dark Knight's message is that when you fight terrorism, there are things that you have to do that are going to be hated by the rest of the world – you have to be "something other than a hero." I believe this correlates to the U.S.'s unpopularity throughout the world due to its involvement in Middle East conflict. Heavy stuff for a comic book film, but I truly believe this is part of what Nolan is trying to say with this movie.
- Again, let me just say that Ledger was AMAZING. And his "pencil trick" was the greatest magic trick I have ever seen. Wow.
- I loved the movie, but my one problem was that the plot was hard to follow at times. It is a dense story line, especially for a 2 1/2 hour movie. I had to really concentrate to follow along.
- I thought the way Harvey Dent was "turned" made a lot of sense, and his character worked into the plot perfectly. I'm always worried that too many villains will muddle up a movie (see Spiderman 3). Bruce Wayne's character was essentially diminished in The Dark Knight, but really, after Batman Begins, what more was there to tell? My one complaint with Dent was that his "accident" was a little anti-climactic. I was expecting a big explosion and a horrifying transformation, but I just got a small fire and a cut to a hospital room. Bo-ring!
That's all folks! Go see HB2! It is 5th at the box office after being passed up by DK, Mama Mia!, Journey to the Center of the Earth, and Hancock (which came in at #2??). Come on, people – Hellboy deserves better!

Jim Gilchrist, a founder of the Minuteman Project, on plans to stop illegal immigration at the Mexican border:
"If you are familiar with the Normandy invasion of France in 1944, then you have an idea how large and logistically complicated this event will be."
So we should be prepared to see at least five divisions of soldiers and artillery behind thousands of fortifications and mines against 150,000 immigrants and refugee children in 4,000 landing craft supported by 1,200 warships.
Not to mention thousands of airborne immigrants parachuting behind our lines.
Summer tourists may want to avoid Texas for a while.

As long as we're at it, a reminder that the proper closing of a letter to the pope is:
"Prostrate at the feet of Your Holiness and imploring the favor of its apostolic benediction, I have the honor to be, Very Holy Father, with the deepest veneration of Your Holiness, the most humble and most obedient servant and son/daughter."

Series: The DUFF #1
Published by Poppy on September 7, 2010
Genres: Contemporary, Young Adult
Pages: 280
Format: Hardcover
Source: Purchased
Also in this series: Lying Out Loud
Add to: Goodreads
Seventeen-year-old Bianca Piper is cynical and loyal, and she doesn't think she's the prettiest of her friends by a long shot. She's also way too smart to fall for the charms of man-slut and slimy school hottie Wesley Rush. In fact, Bianca hates him. And when he nicknames her "the Duff," she throws her Coke in his face.
But things aren't so great at home right now, and Bianca is desperate for a distraction. She ends up kissing Wesley. Worse, she likes it. Eager for escape, Bianca throws herself into a closeted enemies-with-benefits relationship with him.
Until it all goes horribly awry. It turns out Wesley isn't such a bad listener, and his life is pretty screwed up, too. Suddenly Bianca realizes with absolute horror that she's falling for the guy she thought she hated more than anyone.
What I Thought…
- The Duff is very blunt. There was some swear and there is definitely some sex. A lot more than in typical YA books.
- The Duff is very fast paced. I read this book in the wee hours of the morning during Read-a-Thon and despite my tiredness I could not go to bed until I finished this book. I just had to know what happened.
- My only real complaint about The Duff is Bianca's relationship with her father. I mean seriously? It doesn't make any sense for her to behave this way. She was an enabler in a situation that did not need an enabler!
- As much as I liked the book, I didn't like Bianca, but I didn't not like her either. Part of it was how she dealt with her father and the other part was how she treated her friends. I did feel sorry for her (her mother won't be winning any "mother of the year" awards) but she made a lot of choices that frustrated the hell out of me.
- However, I loved Wesley. I know that sounds strange (he's a man-slut after all) but he is so likeable. He's everything you want in a guy, the man-slut issue set aside of course. He was caring, funny and mostly sweet. He has a crummy family too and I wish we could have saw a little bit more of it.
- I liked Bianca's friends. At first I kind of felt like they were using her a bit, but that's really not the case as they genuinely care about her. Both Bianca's and Wesley's parents had some major issues. Everything was tied up pretty nicely at the end, but since I expected that it didn't really bother me.
Overall this was a quick and enjoyable read.

This erotic DVD will show you how to add sizzle to a committed relationship and offers visual examples for you to try with your own partner. Created by famous sex educator Jamye Waxman, you're sure to appreciate both the sensual visuals and intelligently delivered tips.
With three arousing sex scenes, there is plenty of hot action to get you in the mood and educate at the same time. Naomi and Justin demonstrate climactic mutual masturbation, Jayna and Nat use roleplay to spice things up, while Lexi and Ben will show you how anal sex can be both fun and pleasurable.
An excellent film to put the sexual spark back in your relationship without being boring to watch, Personal Touch Volume 2: Seeking Monogamy Without Monotony is a great way to enhance your intimacy.
Catalog ID: ENT74596
See Seeking Monogamy Without Monotony image.
This DVD is definitely worth it. It's not your run of the mill boring old do it this way, or try it this way that doesn't really show you anything and just hints at the nudity and sex. This DVD delivers with full-blown hardcore sex scenes and close-ups.
If you've been married for 20 years, there's not much chance that you'll learn much from this movie; and if you've been watching pornos together for years, this probably will not impress you. But if you and your spouse are in a fairly new marriage, and you think you might be interested in watching porn together, this is a good step into it.
