Can Reptile Embryos Influence Their Own Rates of Heating and Cooling?
Previous investigations have assumed that embryos lack the capacity of physiological thermoregulation until they are large enough for their own metabolic heat production to influence nest temperatures. Contrary to intuition, reptile embryos may be capable of physiological thermoregulation. In our experiments, egg-sized objects (dead or infertile eggs, water-filled balloons, glass jars) cooled d...
متن کاملSolid water phantom heat conduction: Heating and cooling rates
Solid water is often the phantom material of choice for dosimetry procedures in radiotherapy high-energy X-ray and electron beam radiation calibration and quality assurance. This note investigates variation in heat conduction that can occur for a common commercially available solid water stack phantom when a temperature differential occurs between the phantom and ambient temperature. These vari...
متن کاملChildren’s own names influence their spelling
We analyzed spellings that were produced by children in kindergarten (N = 115), first grade (N = 104), and second grade (N = 77) in order to determine whether children’s own names influence their spellings of other words. Kindergartners overused letters from their own first names (or commonly used nicknames) when spelling. Kindergartners with longer names, who had more own-name letters availabl...

15 صفحه اولLongevity Expectations and Death: Can People Predict Their Own Demise?
Many economists are convinced that when individuals are asked to formulate probabilities they are unlikely to do it correctly (Mark J. Machina, 1990). However, the same analysts would likely add that people do have a reasonably articulated, but biased, internal scale for risk perceptions. As a result, the extent of bias in these subjective perceptions has been an important unresolved issue. For...
