Leptin is a hunger-suppressing, fat-burning hormone that is naturally released sometime around sunset. However, leptin won’t be released if there is insulin in the bloodstream, and insulin is released in response to food intake, especially carbs. This is why dinner should be light, early and...
Things made from nylon are durable as long as they are not exposed to phenols, alkalis or iodines. These chemicals will dissolve the cloth. Nylon will also lose its integrity if it is in contact with dilute acids for too long. On the other hand, oils, solvents, and alcohols do not adv...
The first three miles drag on quite awhile, and near the very end of that it starts to pour; I refill a water bottle from water runoff flowing over a tree root on the trail (adding iodine, of course) and head on to Wilbur Clearing Lean-to to eat lunch, hole up, and wait out ...
susceptible tissue cultures. One part of this new test took up the newly developed technique of labeling antigens or antibodies with radioactive substances such as iodine-125 which had already facilitated e.g. the detection of insulin and other small molecules by biophysical techniques. Solid phase...
alone. Her inner self was a friend with whom she could carry on a conversation, that silent voice who posed the vital Socratic question: ‘What do you mean when you say …?’ The self, Arendt declared, ‘is the only one from whom you can never get away – except by ceasing to ...
and the amount of radioactive iodine 125 on the solid phase (at the time, a plastic bead) was measured. Since radioactivity can be detected with very high sensitivity, the process opened new dimensions in detection sensitivity that could be pushed from several micrograms/ml to a few nanograms...
During nuclear decay a ^{238}U atom can break apart into a helium-4 atom and one other atom. Assuming that no subatomic particles are destroyed during this decay process, what is the other element produced? When iodine-131 undergoes beta decay, ...
The first is a custom-built system that is tuned to the yellow 589 nm resonance line of neutral sodium, creating a guide star at an altitude of about 95 km by exciting naturally occurring sodium atoms in the Earth’s upper atmosphere. The second type is tuned to green or even ultraviolet...
