The concept of essence has played an important role in the history and development of philosophy; and in no branch of the discipline is its importance more manifest than in metaphysics. Its significance for metaphysics is perhaps attributable to two main sources. In the first place, the concept may be used to characterize what the subject, or at least part of it, is about. For one of the centra...

an experiment was conducted to evaluate the effect of fennel essence on performance, egg quality and ovarian morphology of commercial laying eggs for ten weeks. in this experiment, one hundred and forty 30-wk-old commercial egg laying type hy-line (w36) were randomly assigned into 4 treatments with 5 replicates and 8 birds per each. treatments were a control (0.0% essence) and diets containing ...

Background: Rhinitis, which occurs most commonly as allergic rhinitis and affects 20% of the world’s population, is a major health care burden causing significant morbidity. Considering the high prevalence of allergic rhinitis and anti-inflammatory effects of thyme, a favorite condiment, we performed a randomized clinical trial to determine whether thyme can relieve allergic rhinitis symp...

In the construction of a large software system, it is inevitable that some aspects of program behavior will cut across the structure of the code. The changes that are needed to support a new feature, for example, may be spread across several different points in the original program, making them harder to maintain and harder to reuse. The designers of “aspect-oriented” programming languages aim ...

ESSENCE is a hash function submitted to the NIST Hash Competition that stands out as a hardware-friendly and highly parallelizable design. Previous analysis showed some non-randomness in the compression function which could not be extended to an attack on the hash function and ESSENCE remained unbroken. Preliminary analysis in its documentation argues that it resists standard differential crypt...

D riving the rapid advance in knowledge of peptidebinding to major histocompatibility complex (MHC) molecules is the prospect of predicting which peptides from foreign proteins are likely to be antigenic, and thus effective immunogens in vivo. Despite the numerous peptides that theoretically could be generated from a foreign protein, in practice cytotoxic T lymphocytes (CTL) focus upon just a f...

P N Rastogi is Professor of Sociology, Department of Humanities and Social Sciences, at the Indian Institute of Technology, Kanpur. The success of any organization depends on its leadership. Although a good deal of research has been done on leadership, it is difficult to say what it is. Recent research classifies leaders broadly into two types: transactional and transforming (Burns, 1978). In t...

We present a model independent method of reconstructing the Lagrangian for the k-essence field driving the present acceleration of the universe. We consider the simplest k-essence model for which the potential is constant. Later we use three parametrizations for the Hubble parameter H(z), consistent with recent the SN1a data, to yield the Lagrangian F . Our reconstruction program does not gener...

In most industries, ranging from information systems development to construction, an overwhelming proportion of projects are delayed beyond estimated completion time. This fact constitutes somewhat of a puzzle for existing theory. The present paper studies project delays and optimal contracts under moral hazard in a setting with time to build. Within this setup, project delays are found to be m...

A research study was conducted to evaluate the effects of three herbal extracts and an antibiotic –virginiamycinon growth performance, immune system, blood factors and selected intestinal bacterial populations in broiler chickens. A total of four hundred and eighty 1-day old male broiler chicks were assigned to the basal diet (control) , basal diet supplemented with 15 ppm of virginiamycin, bas...
