Single Phase Deep Borewell Pump with 3 Capacitors or Single Capacitor
I need clarification from pump expert, i.e., for a single phase submersible bore well pump usually there is starter kit consisting of 2 wires( Phase & Neutral) converted to R,Y, B through 3 capacitors. Why do these 3 capacitors required. We found some starter kits available in local market with
Heating Under Suspended Wooden Floors
I am considering underfloor heating in the uk.
The floors are suspended wood on wood joists.
I have been advised that this is a bad idea. However, as the temperature envisaged is around 30 to 35 C, and I intend to use rockwool insulation under the heat transfer system stuffed into the
More about presentations at AACR10
Five presentations at the 101th annual meeting of the American Association of Cancer Research were highlighted a news release from Geron Corporation (dated March 3, 2010). One presentation that had an explicit focus on CSC was this poster:
Imetelstat, a telomerase inhibitor in phase I trials in solid tumor and hematological malignancies, has broad activity against multiple types of cancer stem cells [Presentation Abstract].
Also mentioned in the news release was an oral presentation by Jerry W Shay, given as part of the Major Symposium entitled: Role of Telomeres and Telomerase in Chromosomal Stability and Disease [Session Detail]. The presentation was:
Role of telomerase in normal and neoplastic stem cells [Presentation Abstract].
Another poster about the telomerase inhibitor imetelstat (GRN163L) was:
Sensitivity and resistance of non-small cell lung cancer to the telomerase inhibitor imetelstat [Presentation Abstract].
Comments: A search of the ClinicalTrials.gov database for GRN163L revealed 6 trials. Four were ongoing, but not recruiting participants. Two were still recruiting: 1) Safety and Dose Study of GRN163L Administered to Patients With Refractory or Relapsed Solid Tumor Malignancies; 2) A Study of GRN163L With Paclitaxel and Bevacizumab to Treat Patients With Locally Recurrent Or Metastatic Breast Cancer.
An analogous search for imetelstat yielded the same 6 trials. All 6 trials have been sponsored by Geron Corporation.

- Distinct expression levels and patterns of stem cell marker, aldehyde dehydrogenase isoform 1 (ALDH1), in human epithelial cancers by Shan Deng and 15 co-authors, including George Coukos and Lin Zhang, PLoS ONE, 2010(Apr 21); 5(4): e10277 [Connbotea bookmark][PubMed Citation][OA full text]. Last sentence of the abstract:
As a novel cancer stem cell marker, ALDH1 can be used for tumors whose corresponding normal tissues express ALDH1 in relatively restricted or limited levels such as breast, lung, ovarian or colon cancer.
- AACR: Are Cancer Stem Cells Vulnerable to Trastuzumab? By Ed Susman, MedPage Today (Apr 19) [FriendFeed entry][AACR10 abstract]. Excerpt:
Mathematical modeling suggests that even in women whose breast cancer does not overexpress the HER-2 gene, treatment with trastuzumab (Herceptin) in the adjuvant setting could wipe out cancer stem cells, researchers reported here.
Some nurses paid more than family doctors – CNN
Primary care doctors were offered an average base salary of $173,000 in 2009 compared to an average base salary of $189,000 offered to certified nurse anesthetists, or CRNAs.
It's the fourth year in a row that CRNAs were recruited at a higher pay than a family doctor.
Jeffrey Benabio, MD - And soon doctor of nursing programs will graduate nurses who call themselves "doctor" in clinic. Physicians have been asleep at the wheel.
http://en.wikipedia.org/wiki/Doctorate_in_Nursing
Francesco Diana - without words
Anne Marie Cunningham - Both of these are very high salaries. As @scanman points out, they are unobtainable for most people working in health in India and countries. Can we tolerate such global inequality?
How should salaries in any part of the world be determined? Are both these groups paid too much?
At the moment there is a great deal of uncertainty on how the role of a doctor differs to the role of a nurse. Professor Alan Maynard suggests that professions are bad for healthcare. http://www.healthpolicyinsight.com/?q=node/458 What do you think?

Turning medical residents away from copy-and-paste culture facilitated by EMR
From MedCityNews:
Cleveland VA is trying to cut out the burgeoning subculture of “copy-and-paste”: A phenomenon made possible by electronic medical records in which physicians copy old information about a patient and paste it into a new section of the chart.
The practice is seen by medical residents as a time-saver but the attendings consider it an “egregious problem” because the practice has the potential to perpetuate mistakes. For example, someone might copy and paste information from a patient’s medical history without verifying that the information is correct. Any errors that might exist will be repeated.
EMR can’t just disable the copy-and-paste function, since such a move would impact other programs.

Thoughts on Transhumanism From Humanity+ UK
An attendee at the Humanity+ UK 2010 conference offers thoughts on transhumanist goals: “The convergence of current technologies such as nanotechnology, biotechnology, information technology and cognitive science (NBIC) and future technologies such as artificial intelligence, mind uploading, cryonics, and simulated reality, is truly inspirational. … I think we all have a vested interest in Aubrey de Grey’s idea that aging is simply a disease, and a curable one at that. His plan is to identify all the components that cause human tissue to age, and design remedies for each of them through his approach called SENS (Strategies for Engineered Negligible Senescence). Once we can extend human life spans by thirty years, we’re well on our way to immortality. Aubrey de Grey claims that the first human being to live a thousand years has probably already been born. From the way he talks, the biggest challenge in the race against mortality is funding! So I highly encourage those of you with means and an interest to donate to the SENS Foundation. … Another fascinating speaker was David Pearce, advocating the abolition of suffering throughout the living world. … He argues that as we develop these technologies, it is both our moral and hedonistic imperative to rid all sentient beings of pain.”

Looking to the Future of Personalized Medicine
Sequencing our own DNA and cross-referencing the results against the best of present scientific knowledge will soon be cheap and routine. This is an example of the sort of incremental progress in medical technology that is increasing human life expectancy year after year: a little more prevention here, a little better insight into how to cure there. From ScienceDaily: “For the first time, researchers have used a healthy person’s complete genome sequence to predict his risk for dozens of diseases and how he will respond to several common medications. The risk analysis [also] incorporates more-traditional information such as a patient’s age and gender and other clinical measurements. The resulting, easy-to-use, cumulative risk report will likely catapult the use of such data out of the lab and into the waiting room of average physicians within the next decade, say the scientists. … The $1,000 genome is coming fast. The challenge lies in knowing what to do with all that information. We’ve focused on establishing priorities that will be most helpful when a patient and a physician are sitting together looking at the computer screen. … Information like this will enable doctors to deliver personalized health care like never before. Patients at risk for certain diseases will be able to receive closer monitoring and more frequent testing, while those who are at lower risk will be spared unnecessary tests. This will have important economic benefits as well, because it improves the efficiency of medicine.”

I Really Don’t Want to Call This ‘London Calling’
I'll admit that neither Jo nor I were expecting a lot from London. We both had an image of Coroesque houses lining toonarrow lanes the pavements packed with pedestrians in heavy coats huffing steam. We were both pleasantly surprised when we stepped out of the underground right into the heart of regent street its elegant white walled shops curving towards the heart of the city and some of the

Jo and I have managed to survive our first week away from home so I thought it best thanks to urging from several others to update the travel blogAfter a farewell embrace with the parents and a few tears from Jo not me too staunch we set out. Only minutes later Jo was already in awe of my absentmindedness as I managed to leave our laptop at the first xray we came across and the org
Into India… Delhi Agra.
Having flown from Kathmandu arriving in Delhi with Lawrence was a bit confusing we were told on the plane that it was 45 degrees celcius yet it didn't feel too hot a dry nonhumid climate makes all the difference. We were told that arriving in India can be a shocking and overwhelming experience but the airport was huge pristine airconditioned efficient and easy with the exception of

Fun in the Snow at Crater Lake National Park
From Bend we headed for South Oregon and Crater Lake National Park. We decided to buy some snow chains for our rental cars tyres not that we knew how to use them. As we did not know what the road conditions would be like around the National Park and we had seen signs along the way saying that snow chains were required. It was about a 2 hour drive from Bend and we could already see snowcapped m
Feeling nonBlue in The Blue Mounatins
The time was right to get out of rural North QLD for another planned weekend this time to coincide with my birthday a few days earlier and just because. I have heard so many things about this region and it lived up to be expectations in fact a slice of NZ climate and in some ways scenically the flora especially ponga ferns tussock grasses and climatically cool clear mornings.

spiders and toucans and monkeys oh my….
We finished off our time in the jungle. We saw lots of monkeys sloths and many colorful birds. We took a night hike to see the many insects that are out at night. Our guide took us to his home which was a fascinating visit. He and his wife and six kids live in a house made up of two buildings up on stilts connected by a sixfootlong board bridge. Each building was about 12 foot square
Say hello to the Van
Well I picked up the camper van this morning and drove all the way to Burnaby it must be all of 10 miles from downtown Vancouver. Staying at a relatively plush RV site it's got a pool AND a gym so it must be posh. Feels like a tank to drive. Not quite got used to just how wide it is 8.5ft but the cab itself is probably only just over 7ft wide which makes it quite tricky. Backing int
