The University of Calcutta is a public state university located in Kolkata , West Bengal, India established on 24 January 1857. By foundation date, it is the first institution in South Asia to be established as a multidisciplinary and secular Western style university. Within India it is recognized as a Five Star University and a Centre with Potential for Excellence by the University Grants Commission and the National Assessment and Accreditation Council. There are four Nobel laureates associated with this university: Ronald Ross, Rabindra Nath Tagore, C. V. Raman and Amartya Sen.Within all state universities all over India, this university had the highest number students who cleared the doctoral entrance eligibility exam in the science conducted by Government of India's National Eligibility Test to become eligible to pursue research with full scholarship awarded by the Government of India.It is a state-government administered urban-based affiliating and research university. It has its central campus in College Street . Its other campuses are in Rajabazar , Ballygunge , Alipore , Hazra and South Sinthi. Wikipedia.

In this paper an integrated production-inventory model is presented for supplier, manufacturer and retailer supply chain, considering perfect and imperfect quality items. This model considers the impact of business strategies such as optimal order size of raw materials, production rate and unit production cost, and idle times in different sectors on collaborating marketing system. The model can be used in industries like textile and footwear, chemical, food, etc. An analytical method is employed to optimize the production rate and raw material order size for maximum expected average profit. An example is illustrated to study the behavior and application of the model. © 2010 Elsevier B.V. All rights reserved.

By late 18th or early 19th century, albino rats became the most commonly used experimental animals in numerous biomedical researches, as they have been recognized as the preeminent model mammalian system. But, the precise correlation between age of laboratory rats and human is still a subject of debate. A number of studies have tried to detect these correlations in various ways, But, have not successfully provided any proper association. Thus, the current review attempts to compare rat and human age at different phases of their life. The overall findings indicate that rats grow rapidly during their childhood and become sexually mature at about the sixth week, but attain social maturity 5-6 months later. In adulthood, every day of the animal is approximately equivalent to 34.8 human days (i.e., one rat month is comparable to three human years). Numerous researchers performed experimental investigations in albino rats and estimated, in general, while considering their entire life span, that a human month resembles every-day life of a laboratory rat. These differences signify the variations in their anatomy, physiology and developmental processes, which must be taken into consideration while analyzing the results or selecting the dose of any research in rats when age is a crucial factor.

Techniques generally disclosed herein relate to computation of a guard zone of a three-dimensional object. In some examples, guard zones may be computed by identifying intersection lines that couple adjacent planes of an object, and categorizing an external angle at an intersection line between adjacent planes as concave or convex. In some embodiments, for convex angles, a cylindrical surface can be determined that is located about an outside surface of the object and centered along the intersection line between the adjacent planes. In some embodiments, for concave angles, the external angle can be bisected with a bisection plane. A guard zone may be formed by one or more of (i) providing a guard zone plane parallel to the object that is a tangent to a given cylindrical surface, (ii) providing a guard zone plane parallel to the object that intersects a given bisection plane, and/or (iii) coupling adjacent guard zone planes.
