Each year, more than 330 million tons of plastic are produced worldwide. The main consumers plastics the packaging (40%), building (20%) and automotive (8%) industries, as well for manufacture household appliances. vast majority industrial not biodegradable and, therefore, create environmental problems due to increase in amount solid waste. Studies have been conducted produce materials such bio...

We study the effect of new product introduction on firm value. Using a unique sample on mobile phone handset introduction by 16 major handset manufacturers over 10 years, we distinguish between imitative product introduction and truly innovative product introduction. We find that while most product introduction is imitative, both types of innovation increase firm value. However, truly innovativ...

Publication has become a burning issue among Indian medical fraternity owing to certain academic and professional necessities. The large number of submissions to the anaesthesia journals has resulted in accumulation of too much below average scientific material. A properly written manuscript is the dream of every editor and reviewer. The art of preparing a manuscript can be acquired only by fol...

P aul Samuelson (1969) was once asked by a physicist for a law in economics that was both nontrivial and true. This is a difficult challenge, as many (roughly) true results are in the end rather trivial (for example, demand curves slope down), while many nontrivial results in economics in fact require too much sophistication and rationality on the part of the agents to actually hold true in pra...

The aim of this paper is to establish some new common fixed point theorems for generalized contractive maps in fuzzy metric space by using property (E.A.), common property (E.A.), JCLRST property and CLRS property. Our results improve and extend the results of Chauhan et al. [1] and Sedghi et al. [2] besides several known results. We also furnish an illustrative example in support of our results.

The purpose of this study was to describe how companies in pharmaceutical and biological sectors can ensure their position in different markets by relying on sustainable, competitive advantages, resulting from the use of a well-defined marketing model with particular emphasis on brand improvement. As competition becomes more intense among companies and phenomena such as global marketing grow in...

In this paper, we study the recognition complexity of discrete geometric 2gures (rectangles, squares, circles, ellipses) on a retina by diameter-limited and order-restricted perceptrons. We construct a diameter-limited recognition perceptron for the family of rectangles, beginning with local con2gurations, which is di6erent from the one shown by Minsky et al. (Perceptrons: An Introduction to Co...
