A new model is presented herein to calculate optimal value for ultra-cold neutron (UCN) production rate of a UCN source. The cold neutron (CN) converter is the main component of UCN source. In this paper, we study the UCN source which contains the D2O neutron moderator, the sD2 converter, 590 Mev proton beam, and the spallation target (a mixture of Pb, D2O and Zr). In order to determine the qua...

l. A new formula which correctly expresses the percentage contribution of increased heart rate to increased oxygen transport during activity is presented. 2. The percentage contribution is reported for the turtles Pseudemys scripta and Terrupene ornata at body temperatures of 1@-4O”C. 3. Corrected values for this parameter in reptiles studied at 30°C by other authors are also presented. SEVERAL...

Background: The importance of ergonomics is to create fit between work and human physiology using assessment methods of physical, physiological and subjective evaluation. The most commonly used tool for assessment of subjective symptoms is Borg scale during physical work and heart rate in physiological situations. This study is based on a subjective and physiological assessment during hard work...

The aim of this paper is to present a new numerical method for solving the Bagley-Torvik equation. This equation has an important role in fractional calculus. The fractional derivatives are described based on the Caputo sense. Some properties of the sinc functions required for our subsequent development are given and are utilized to reduce the computation of solution of the Bagley-Torvik equati...
