By using an iron alloy that transforms slowly to bainite at a low temperature, it has been possible to study the development of the upper bainite under the influence of exceptionally large stresses, which are nevertheless below the yield strength of the parent austenite. It is found that a uniaxial stress whose magnitude is below the elastic limit, strongly favours the growth of compliant varia...

An attempt was made to detect interaction between photosynthesizing algae and denitrifying bacteria by cultivating Chlorella sp. with Pseudomonas s t u t d . Denitrification was inhibited by illumination of the mixed culture after a dark period of 3 hr. It is suggested that immediate inhibition is due to the molecular oxygen produced by the suspended algae and distributed homogeneously in the c...

The injection of the toxic proteose obtained from the contents of the obstructed small intestine causes a definite impairment of the eliminative function of the kidneys as shown by a decreased capacity to excrete urea, sodium chloride, and phenolsulfonephthalein. This involvement of the renal function is similar to that shown by the preceding report (1) to accompany the intoxication of intestin...

This article is devoted to different skin diseases on fingertips which have an impact to the process of fingerprint acquirement or recognition. There are many people, who suffer under such dermatologic diseases and are therefore excluded from the set of users of a biometric system. The classification of skin diseases is made from the medical point of view. This classification is followed by the...
