    Description: Voltage flicker refers to a slow-0.5 to 30 Hz-modulation of the power system voltage magnitude. This periodic fluctuation can be modelled as an amplitude modulated signal, where the fundamental power frequency represents the carrier signal and the voltage flicker represents the modulating signal. An algorithm based on this premise is developed to estimate the instantaneous magnitude and frequency of the voltage flicker. The algorithm, which is based on Kalman filter estimation, can also be used to predict the instantaneous flicker level.〈 〉

    Description: Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake’s digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and conservation biology—and they can be further extrapolated in economics, neurobiology, and computer science. Foraging is the first comprehensive review of the topic in more than twenty years. A monumental undertaking, this volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behavior, caching behavior, parental behavior, antipredator behavior, social behavior, population and community ecology, herbivory, and conservation. Considering a wide range of taxa, from birds to mammals to amphibians, Foraging will be the definitive guide to the field.

    Description: Functional health outcomes resulting from intensive insulin regimens may differ depending upon the age of the diabetic patient. This study tested the hypothesis that health functioning is poorer for younger insulin-dependent diabetic (IDDM) patients following a change to the insulin infusion pump regimen, with progressive improvements occurring in functional health status at higher age levels. Thirty IDDM patients aged 10-47 years were administered health status instruments prior to changing to the new regimen, and again six months later. The instruments assessed physical, cognitive, psychological, and social health functioning. When compared at six months to an age-matched control group on conventional insulin therapy, declines in social activities were found for younger insulin pump patients, with improvements occurring linearly as age increased. Lower performance levels were also found for the younger patients in Conceptual Quotient (CQ), an indicator of-cognitive functional status, with progressive improvements with age through the early 30s. However, corresponding declines in function occurred at the oldest age levels. Adaptation to an intensive diabetes regimen appears to be more difficult at younger and older age levels.

    Description: SINCE 1954 the hypoglycemic sulfonamide, carbutamide (l-butyl-3-sulfanilylurea)∥ has been undergoing extensive clinical trial in the treatment of diabetes mellitus. In preliminary reports of these studies, few toxic reactions were described. 1 2 3 These included several cases of drug fever and rash that cleared promptly on discontinuance of the drug. A case of hepatitis that occurred in Germany concomitant with the administration of carbutamide was believed to be on an infectious basis. In more recent reports, Ridolfo and Kirtley 4 and Kinsell 5 have described cases of progressive leukopenia that necessitated termination of therapy. In our series of 48 cases side reactions were considerably more . . .
