The article presents briefly the main mechanisms of cadmium carcinogenesis and the most important sites of cancer (lung, breast, prostate, testes, kidney) induced by cadmium. In spite of some evidence showing carcinogenic potential of cadmium, further research is still required to elucidate the relative contributions of various molecular mechanisms involved in cadmium carcinogenesis.

Aristotle's De motu animalium

De Motu Locali Animalium

The bright light of William Harvey's discovery of the nature of the blood's circulation usually outshines his other contributions, notably the important studies on the embryology of the chick and the deer. However, the Exercitationes de generatione animalium at least was published (1651). Now Dr. Whitteridge, at the invitation of the Royal College of Physicians, has made accessible a virtually ...

Minimization of torque ripples in BLDC motors due to phase commutation - a review

The smoothness of variable speed drive operation is critical and a viable measure used in the design and development of motion control applications. The torque produced in a brushless DC (BLDC) motor with trapezoidal back electromotive force (BEMF) is constant under ideal conditions. However, in practice, torque ripple appears on the delivered output torque. Some of these ripples result from th...
