I was wondering, "what could be the use/application of control cables rated 2kV".
You see, I reside in South Africa and work for a petrochemical company where most (if not all) of our control cables are rated the normal/usual 600V/1000V. NB:- our control circuits use 115Vac or 110Vdc.

350.org co-founder Bill McKibben write the article below on how to change the dynamics of the climate debate in our country. They want it spread around, so here it is. It should probably be published in every newspaper in the country. Why isn’t McKibben a syndicated columnist? If only the general public was interested enough to read articles like this. They are the people who need to read these articles, not McKibben’s many already-fans.
We’re Hot as Hell and We’re Not Going to Take It Any More
Bill McKibben, TomDispatch regular and author of the invaluable new book, Eaarth: Making a Life on a Tough New Planet, assesses our national moment in the heat and just how wilted we’ve seemed to be.. . . .
Three Steps to Establish a Politics of Global Warming
By Bill McKibben
Try to fit these facts together:
* According to the National Oceanic and Atmospheric Administration, the planet has just come through the warmest decade, the warmest 12 months, the warmest six months, and the warmest April, May, and June on record.
* A “staggering” new study from Canadian researchers has shown that warmer seawater has reduced phytoplankton, the base of the marine food chain, by 40% since 1950.
* Nine nations have so far set their all-time temperature records in 2010, including Russia (111 degrees), Niger (118), Sudan (121), Saudi Arabia and Iraq (126 apiece), and Pakistan, which also set the new all-time Asia record in May: a hair under 130 degrees. I can turn my oven to 130 degrees.
* And then, in late July, the U.S. Senate decided to do exactly nothing about climate change. They didn’t do less than they could have — they did nothing, preserving a perfect two-decade bipartisan record of no action. Senate majority leader Harry Reid decided not even to schedule a vote on legislation that would have capped carbon emissions.
I wrote the first book for a general audience on global warming back in 1989, and I’ve spent the subsequent 21 years working on the issue. I’m a mild-mannered guy, a Methodist Sunday School teacher. Not quick to anger. So what I want to say is: this is fucked up. The time has come to get mad, and then to get busy.
For many years, the lobbying fight for climate legislation on Capitol Hill has been led by a collection of the most corporate and moderate environmental groups, outfits like the Environmental Defense Fund. We owe them a [...]
I want to purchase solar panels for a load of 4KW
whats the ideal watt/panel and what should be technical specification of the panel.
Thanks
Please help me identify this corner sealing and finish material - look at the overall view, and then upper and lower details at right [more below pictures].

Who are all the INDIAN 'U' STAMP CERTIFIED manfacturer
a lady have certain number of birds as of now.
if she sells 75 of them..she will have food lasting for extra 20 days..
if she buys 100 more birds.. she will face shortage of food for 15 days.. i.e 15 days less than present situation.
how many birds she owns?

Hi All,
Basically we are developing a model of car to run on battery bank that will be charged by Solar PV panels.
I want to ask how to synchronise the 4 wheels of a battery operated car.
Will it be OK if 4 DC motors are deployed to power /run the 4 wheels, and how to sync
Dienekes has a post up where he highlights the fact that the recent paper on South Asian metabolic diseases has a figure which elucidates population structure within the region. Accounting for structure is important for genome-wide associations since you might get a spurious correlations if trait value/disease frequency is simply tracking cryptic population variation. Dienekes says:
The existence of two clusters is kind of obvious, while their interpretation is not as dots of the same color appear in both clusters: a placement of these individuals in a global context might have been useful here. Things are clearer at the top cluster which shows a clear gradient anchored by Punjabi Sikh and Hindu Tamils on either end.
Also of interest is the group of isolated Muslim/Christian individuals on the left which deviate strongly from the mainstream; these probably represent exogenous elements that don’t resembe the bulk of the Indian population.
The second issue is easily addressed. The Christian outliers are both give English as their native language. That suggests to me that they’re Anglo-Indian, a community of mixed South Asian and European origin. South Asian Muslims are overwhelmingly of indigenous origin. But, a minority of the Muslim elite are West Asian, or have substantial West Asian ancestry, as is evident by the fact that they look white. Benazir Bhutto’s mother was of Kurdish and Persian ethnic background (her family was from Esfahan in Iran). I’ve reedited the religious & linguistic PC plots to fit onto the screen.
So what’s going on with the cluster which extends along the second principal component? The first component is probably just a European/West Asian-South Asian axis of variation. But I don’t understand where the variation for the second is coming from. Observe that the one South Indian group, Tamil speakers, are not represented in the secondary cluster. The plot reminded me of something I saw last fall.
Below is figure S4 is from the supplements of Reconstructing Indian population history. I added some labels. The Indian cluster is tight when the genetic variation includes non-Indian groups. But, when you constrain the variation to Europeans and South Asians only, something strange happens:
The Gujarati sample is from Houston, and is from HapMap Phase 3. I have a suspicion that the secondary cluster among the Gujaratis here is of the same class of phenomenon as the secondary cluster in the first plot. The Anglo-Indians and West Asian Muslims serve as rough proxies for Europeans, and you have an expected European-South Asian axis. But you also have this strange orthogonal component. I had assumed that the plot from the Reich et al. paper was an anomaly, but I’m not so sure seeing the second paper.
So, you find yourself as an American teaching in a far away place (Busan, South Korea to be exact)… What do you do now… You write about it. And, Brittany Weyen has being doing just that. As she grows through her experiences, so does her blog. Gotta love her students.

August 4 Woke up today early as usual. I saw Daria's mom before she left for work and she made me promise to eat some breakfast and to wake up Daria. I let her sleep but she work up early anyway. She made us some tortillas with cheese for breakfast that were delicious. Then we sat around watching some tv including a cartoon movie about a horse in the wild west. Weird. Daria's mom came home at
While Phnom Penh we learnt a detailed account of the Khmer Rouge Pol Potrsquos cruel regime which ruled for only a few yet destructive years during the seventies. It was shocking to acknowledge the chilling bloodshed horror and people turmoil that rippled through the country in what historically can be seen as recent times. It was also disturbing to find that it took almost 30 years to bri
August 2 Today I left Krakow. A shame because I really like the town but I have a few more places I would like to go before I go home and I am starting to feel in the mood to go home. I woke up around 8am and went down to search for a hostel in Wroclaw that I would be going to on Tuesday. I booked one that sounded nice and then had breakfast with a bunch of people at the hostel that I have
I guess this is going to be a one country per day trip Today it is Hungry a repeat of National Lampoonrsquos vacation. The good thing about Hungry is there is less traffic but all in all this has not been a pleasurable riding trip thus far too much traffic and too much need to weave back and forth from the overtaking lanes. I also continue to have trouble with the traffic indicators on the
I am currently sitting at the Hongqiao Airport. FREE WIFI I left the hostel this morning at 11301140. Last night I was able to take my suitcase over to Tristan's so I can travel light to Beijing. Yesterday Xuzhi invited me over to her parent's home in Jinshan District which is about an hour away from People's Square. I took line 1 from People's Square to Jinjiang Park where I met Xuzhi at a M
It was time to leave Phi Phi for Ao Nang. We packed our stuff and headed for the boat which took us to Krabi Port. We took a bus into Krabi town which dropped us off at some random guest house and we were off to find a way to Ao Nang. We were about to head to the main bus station which was about a 7 km walk when some random Aussie woman on a scooter informed us of where we needed to go to catc
S'up y'all Hello guys thanks for all the comments and everything its so lovely to hear from all of you.

This is our one only blog from bali as our resort only has wifi in the restaurant area.Lovely resort though right on the beach at legian about 20 minutes from Kuta. The weather here is very nice warm but not hot as its winter no humidity.The traffic is worse than Bangkok the drivers are totally insane especially the motorbikes. They come at you from all directions even on the footpaths which
Today we were heading down to Jens mum and dadrsquos house for breakfast and to start sorting out a few things for the wedding. We had waffles and jam and they were yummy. Margaret Jen and Aya and Abby went into Kalispell which is about 45mins north to get some stuff for the wedding and the week ahead so it was good for the girls to get out and about for a while. We soon headed down to the lake
Today we were heading towards Bigfork and it was going to take about 4 hours so we had brekkie in the hotel first. We had to get some dresses for the girls as Jake and Jen asked them to be flower girls for the wedding. So we went to Spokane Valley mall and got some nice outfits for them and some shoes. On our travels we crossed into Idaho State which we travelled for about an hour. Then we cross
