The interrelationships of dietary fat and energy, growth rates and anthropometry, and breast carcinogenesis have been examined by a diverse array of approaches throughout the last 50 y as new investigative tools have been developed by laboratory scientists and epidemiologists. A consensus among investigators has not emerged, however, and dietary recommendations for breast cancer prevention have...

Landscape can bc considered a spatially heterogeneous area. and spatial pattern refers 10 the arrangement of strucrural heterogeneity of environments. resource and biological systems in space (Forman et al 1986. Turner 1987. I9S9. Risser 1987. Turner et al 1991). Turner ( 1987. 1989) considered that spatial pattern has important consequences regarding the effective dispersal of organisms among ...

We investigate the instability and nonlinear saturation of temperaturestratified Taylor-Couette flows in a finite height cylindrical gap and calculate angular-momentum transport in the nonlinear regime. The model is based on an incompressible fluid in Boussinesq approximation with a positive axial temperature gradient applied. While both ingredients itself, the differential rotation as well as ...

INTRODUCTION MDMA or ecstasy is a derivative of amphetamines used mostly by young people worldwide. Although the acute effects of this drug are known, the effect of chronic administration is not well studied. Therefor the aim of this study was to determine the effects of repeated (long term) administration of MDMA on rats' memory and their hippocampal cell density. METHOD Young adult male Wis...

This paper presents an approach to real-time rendering of non-planar projections with a single center and straight projection rays. Its goal is to provide the same optimal and consistent image quality GPUs deliver for perspective projections. It therefor renders the result directly without image resampling. In contrast to most object-space approaches, it does not evaluate non-linear functions o...

Mutations in the gene coding for superoxide dismutase 1 (SOD1) are associated with familiar forms of the neurodegenerative disease amyotrophic lateral sclerosis (ALS). These mutations are believed to result in a "gain of toxic function", leading to neuronal degeneration. The exact mechanism is still unknown, but misfolding/aggregation events are generally acknowledged as important pathological ...

This paper presents results of the development and application of a web-based information system, Jeddah CIS, for assisting decision makers in the management of Jeddah coastal waters, in Saudi Arabia. The system will support coastal planning, management of navigation and tackle pollution due to accidents. The system was developed primarily to nowcast in quasi-real time and to deliver short-term...

Today, the publication of microdata poses a privacy threat. Vast research has striven to define the privacy condition that microdata should satisfy before it is released, and devise algorithms to anonymize the data so as to achieve this condition. Yet, no method proposed to date explicitly bounds the percentage of information an adversary gains after seeing the published data for each sensitive...

Change is one of the stable factors in many organisations. Therefor agility is essential for success and good management of knowledge is one of the key factors for success in such organisations. This document describes a model for the organisation of knowledge management. This model is based on a distinguishing of concepts of knowledge: the stock concept and the flow concepts. The importance of...
