Shaping the Toroidal Section of End Mills

The shaping of the toroidal cutting section of end mills is considered. Methods are devised for selecting the positional parameters in shaping the helical rake surface on the toroidal section. Relations are established between the geometric parameters of the end mill in the toroidal section.     

Changes in the kinetics of the hemoglobin, total protein and DNA content in rat erythroid cells in experimental anemia. I. The peripheral blood

Cytophotometry of rat blood erythroid cells during anaemia, induced by phenylhydrazin (4-8 days from the beginning of injections), revealed that all forms of bone marrow containing haemoglobin were thrown into the blood. On its peak (4th day), the greatest contribution in blood haemoglobinization (50%) is made by microcytes. From the 5th day and up to the end of the restoration period the important role in this process is played by macrocytes. From the 6th day the role of normocytes increases, whose contribution by 8th day reaches 70% of the whole haemoglobin amount in blood. In contrary to anaemizated birds, whose erythroid cells ripen in blood, in rats all the transformations of erythron during anaemia are accomplished in bone marrow.     

Isothermal detonation and its stochastic modeling

An isothermal model describing detonation under confined conditions, for example, in a porous medium; in a reasonable approximation is presented. It is shown that such a detonation can be analyzed qualitatively by the stochastic method of cellular automata.Lavrent'ev Institute of Hydrodynamics, Siberian Branch, Russian Academy of Sciences, 630090 Novosibirsk.

Methods of handling of in-bulk agglomeration layer image representation for granulometric composition assessment

The analysis of methods of images handling is carried out, the method of dynamic threshold division which is based on the calculation of weight coefficient of points in the local area is suggested. The method of adaptive adjustment of the size of the local area of the image representation is carried out to define the threshold value. Also methods of binary recursive filtration and mathematical morphology to reduce interference are introduced. The article is published in the original. Evgenii Valentinovich Ershov.

Ultrastructural and biochemical changes of hepatocytes during ether and fluothane anesthesia under experimental conditions

A study was made of a possibility of using Soviet made membranes "Vladipor" with a pore diameter of 16--17 nm for the purpose of concentration and purification of antigenic extracts from stab cultures of S. typhi obtained by the action of typsin, hydrogen peroxide and detergents. Preparations, complete by antigenic structure, were obtained by ultrafiltration, with a good yield. The maximal rate of ultrafiltration was noted in case of "peroxide" antigenic preparations. The use of diafiltration provided a significant reduction of the ash content in the end products.
