why not use salt?

Most ice in the arctic ocean is drift ice. It is floating and moves according to the winds and currents. Sea ice is another word for drift ice. Ice shelves are also technically floating although they are attached to the land so they don't move. Ice shelves are called "fast ice", because it...

Thanks again SW. A focus team meeting was held today regarding the testing plan. Practicality is a major factor, so our team recommendation was to test 28 machines. These are the easiest & cheapest population to test, which also contains the 20 most likely to fail. At least it is a start...

Thanks SW; I do have a MODEL for predicting performance of each machine. Not sure how good it is, but suspect that it is conservative. That is to say, the MODEL seems to be over stating the deterioration of each machine. So, perhaps instead of picking machines at random to test, I could pick...

Need assurance that a population of 185 devices are OPERABLE. A MODEL has been developed for prediction of each devices condition. Periodically, it is necessary to TEST the devices in case the MODEL is wrong. However, it is expensive to TEST these devices. Therefore, it would make sense to...

The weighting factors for x-rays, gamma rays, electrons, positrons and muons is 1. Neutrons range from 2 to 20 depending on their energy. Alpha particles are 20! Consequently, alpha radiation is far more dangerous to human health. X-rays, gamma rays and electrons generally form diffused ions...

Any links supporting NASA's alleged position?

My impression is the timeline outlined in Wikipedia is about all we know from a scientific point of view: http://en.wikipedia.org/wiki/History_of_the_EarthNotice that there was a time that Earth had no atmosphere; immediately after the big impact.

Go shopping for compact fluorescents; they come in different temperatures.

Kevin Costner already did that story with Waterworld.

Cooling; the Milankovitch theory as tuned by Imbrie predicts that the long-term cooling trend which began some 6000 years ago would otherwise continue for 23,000 years. http://math.virginia.edu/~ji2k/Home/Papers/Imbrie-Imbrie.pdf

my bad; it's the Novac7 that uses electrons. Anyhow, the average survival rate for breast cancer patients with a similar diagnosis as my wife are excellent (Invasive Ductal Carcinoma Stage 1, Grade 2 ER/PR positive, clear margins without lymph node involvement). Radiation is considered...

Thanks tiny-tim; I was missing the tissue weighing factor... It's a treatment for Breast Cancer, so that would include both skin and breast tissue. Weighing factors according to Wikipedia: skin 0.01 breast 0.05 However, Wikipedia also claims 1 Gy = 115Rad So, skin dose would be 4.4 Rem...
