Some decompositions of the three-dimensional sphere and three-dimensional ball into Jordan curves are considered. In particular, it is proved that for every strictly positive real number p ≤ 1 there exists a partition of the unit three-dimensional Euclidean sphere into circles whose radii are equal to p. Let S2 be the unit two-dimensional sphere in the Euclidean space R3 and let S3 be the unit ...

The ring-sheared drop is a containerless system where shear imparted by two contact rings, one rotating and the other stationary. In microgravity, aqueous drops can be studied in air at centimeter scale. Drops of this scale also experimentally on Earth, but effects gravity need to mitigated density matching liquid its surrounding fluid. use silicone oil surrounded an solution allows while retai...

not beginning or completing the vaccination schedule as recommended in the expanded programme on immunization is one of the major reasons for low immunization coverage. it should be studied in detail for remedial action, if the objectives of the epi in iran are to be achieved as stated. generally, lack of knowledge, lack of motivation and obstacles ore the basic categorical reasons for low cove...

Abstract Business ethicists disagree on whether John Rawls’s political philosophy can be applied to their questions and concerns. They concur, however, that, if warranted, such an application of his theory would highly instructive for the field. This article scrutinizes that assumption. The paper examines what extent a normative import into business ethics indeed render adequate results. Highli...

This paper addresses the problem of adapting a generic 3D face model to a human face of which the frontal and profile views are given. Assuming that a set of feature points have been detected on both views the adaptation procedure initializes with a rigid transformation of the model aiming to minimize the distances of the 3D model feature nodes from the calculated 3D coordinates of the 2D featu...

Drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. In this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. A video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...
