New PDF release: Microwaves and Thermoregulation

By Eleanor Adair

Microwaves and Thermoregulation emerged from a symposium hosted by way of the loo B. Pierce beginning at Yale college, New Haven, Connecticut, on October 26-27, 1981. the development introduced jointly engineers, actual scientists, physiologists, and psychologists to debate the ways that nonionizing electromagnetic radiation deposits thermalizing power in organic tissues and the way this power can be detected and controlled by means of the unsleeping organism.
The publication starts by way of tracing the heritage of thermal RF-tolerance and of thermoregulation. this can be by way of chapters on themes corresponding to the features of the thermal atmosphere; the microwave stimulus; electromagnetic heating for treatment; the results of thermal (infrared) radiation on people; physique temperature rules in the course of euthermia and hyperthermia; the vital fearful thermoregulatory method; and thermal sensation. different chapters speak about the sensory dynamics of extreme microwave irradiation; thermoregulation in extreme microwave fields; thermoregulatory behavioral responses; and results of long term (subchronic) publicity to vulnerable microwave fields. The publication additionally features a bankruptcy that includes panel dialogue held throughout the symposium, and one who discusses G. A. Sachers free-energy speculation of life-span enhancement.

Download e-book for iPad: Primate Locomotion by Farish A. Jr. Jenkins

By Farish A. Jr. Jenkins

Primate Locomotion discusses researches at the proposal of primate locomotion. it truly is equipped into eleven chapters that conceal biomechanical rules, that are the basis of figuring out of locomotor variations.
This ebook first supplies an advent to parallels and analogs among mammalian and mechanical buildings. It then describes the mechanisms of arboreal mammal locomotion, in addition to the behavioral observations and locomotor styles of tree shrew. The leaping locomotion of Galago alleni and the position of wrist specialization within the locomotor evolution of the Hominoidea also are defined. the next bankruptcy discusses the connection among the mechanical gains of the scapula and shoulder area and the features of locomotor habit. A bankruptcy additionally discusses the adaptive nature of postural habit in quadrupedal primates, represented by means of the recent and outdated international monkeys.
Moreover, this booklet examines the morphological modifications among dwelling Insectivora, Carnivora, Primates, and the correct recognized fossils of Cretaceous and Early Tertiary Eutheria. this can be to judge the origins, evolution, and serve as of the Tarsus. one other bankruptcy offers a practical research of lots of the foot skeleton, essentially, the Lemuriformes. The concluding chapters care for electromyographical stories on gorillas; the mechanics of knuckle-walking; the theories on hominoid phylogeny; and the locomotor variations in prosimians.

Vergleichende Verhaltensforschung und Phylogenetik (German - download pdf or read online

By Wolfgang Wickler

Wie Wolfgang Wickler in seinem kurzen, kompakten und seit seinem erstmaligem Erscheinen im Jahr 1967 immer noch aktuellen Werk zeigt, strebt die vergleichende Verhaltensforschung danach, charakteristische Verhaltensmerkmale und Fähigkeiten von Tieren und Menschen zu beschreiben und zu dokumentieren.  Auch heutige Forschung möchte verstehen, warum und wie diese entstanden sind. Einen nach wie vor wichtigen Forschungsschwerpunkt bildet deshalb die Frage nach der evolutionären Herkunft von Formen, Mechanismen und Funktionen der verschiedenen Verhaltensweisen. 

Erläutert werden die Methoden der Phylogenetik, mit denen guy die Stammesgeschichte rekonstruieren kann. In erster Linie mithilfe des Homologisierens lassen sich Aussagen für die genetisch-organische wie für die kulturelle Evolution, die Traditionen begründet, treffen.

Der Autor beleuchtet Verhaltensweisen, die „historische Reste“ aus der Stammesgeschichte enthalten und eine Rolle als Evolutions-Schrittmacher spielen. Als soziale Signale unterliegen sie der Semantisierung  und der Ritualisation.  In wichtigen Funktionskreisen wie Revierverhalten, Paarbindung und altruistischem Verhalten dienen sie der Anpassung an ökologische und soziale Erfordernisse. Dabei entstehen soziale Verhaltenselemente durch Motivationswechsel aus dem Brutpflege- und Sexualverhalten.

 

Als grundlegendes Werk, das sich zudem durch seinen kompakten Ansatz auszeichnet, gibt Wicklers Buch einen Überblick zum Thema Verhaltensforschung und Stammesgeschichte.
