kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...

A hypothesis is presented that electronic and vibrational resonant energy states are important in biochemical reactions due to their coupling to hydrogen transfer reactions. The hypothesis is based upon (1) the involvement of hydrogen in most biochemical reactions, (2) the unique abiity of hydrogen to act as an energy trap for resonant energy and (3) demonstrations of the coupling of resonant e...

Introduction: Since Curcuma longa extract and curcumin have been shown to be potent antioxidant agents, they were used in cultured adult mouse spinal cord slices to investigate whether they can inhibit apoptosis in motor neurons. Methods: Slices from the thoracic region of adult mice spinal cord were divided into four groups: 1. Freshlyprepared slices (time 0) 2. Control 3. Slices treated by cu...

1his chapter provides an account of the events preceding and contributing to the discovery and the general acceptance of the biochemical option for photosynthesis now known as the C, pathway. We also trace the early stages of the elucidation of the mechanism of this process and 'j" I:; .• its physiological significance. Relationships between plants using alternative biochemical I,' , Ii; '. pro...

the present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (prb), with their reduced forms. the two most frequently used mechanisms of methane combustion (gri3.0 and miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. while the findings of numerical simulation of prb show fi...

introduction: cupping therapy (hejamat) is one of the therapeutic methods used in traditional medicine that it is still common in many of the contemporary societies. in spite of the progress of science, we have less information on the traditional and alternative medicine including cupping.   with the study of mechanism of action of cupping, it will be more convincing for the traditional medicin...

Many protein and mRNA species occur at low molecular counts within cells, and hence are subject to large stochastic fluctuations in copy numbers over time. Development of computationally tractable frameworks for modelling stochastic fluctuations in population counts is essential to understand how noise at the cellular level affects biological function and phenotype. We show that stochastic hybr...
