Phosphorus (P) is the 11th most abundant element of the earth’s crust. Phosphorus (P) is an essential element for all living organisms. The world’s main source of P is phosphate (Pi) rock. It is a non-renewable resource. There is neither any alternative to P nor a synthetic way of creating it. P is involved in various basic biological functions, for instance as a structural element in nucleic a...

The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...

Using a commercially available visual graphical analysis tool, the National Science Digital Library (NSDL) has developed techniques to expedite evaluation of large batches of metadata. These techniques allow efficient and thorough review of large quantities of XML metadata, thus enabling the focus of limited resources on evaluation and manipulation tasks that are most important in our context. ...

BACKGROUND Planned re-laparotomies are a series of surgical interventions that are rarely used and have a high mortality rate. The aim of this study was to investigate the factors affecting mortality and the effectiveness of the use of the Bogota bag for temporary closure of the abdomen in patients for whom re-laparotomy was planned. MATERIAL AND METHODS A retrospective examination was made of ...

Our practice of disseminating, accessing and using information, especially scholarly information, is still largely informed by the nature of pre-electronic media. For example, journals still exist in their traditional forms partly because of the value of the peer review process, which thus far has not yielded to decentralized, distributed and timely alternatives. Similarly, information access i...

In this section of the course we consider the basic questions of image content and re-use. In particular, we describe the physical information content of a typical image, based on the simplest camera model and the complex behavior of light in a 3D scene. After reviewing the important effects contributing to the appearance of an image, we focus on the issue of image re-use: when and how is it po...

Reuse of software components can improve software quality and productivity significantly. This paper mainly concentrates on our approach to reuse assessment, which is a process of identifying and assessing the characteristics of a reusable component based on a set of well-defined reuse guidelines. This paper also proposes a scheme for measuring reuse potential. These techniques have been succes...

A design pattern description is much more complex than a semi-formal solution, often restricted to a class diagram. Applying a pattern mainly depends on the solution specification but a lot of useful information can be found into other items. Neglecting variants of the main solution the pattern engineer might explain can be detrimental to the pattern itself because, most of the time, they affec...
