Abstract Exposure to the hight-fat diet may alter control of food intake promoting hyperphagia and obesity. The objective this study was investigate effects on dopamine receptors (drd1 drd2), proopiomelanocortin (pomc), neuropeptideY (npy) genes expression, preference in adult rats. Wistar female rats were fed a or during pregnancy lactation. offspring allocated into groups: Lactation – Control...

The goal of this paper is to give a mathematical model describing the global behaviour of the nuclear waste disposal process. The physical situation can be described as an array made of high number of alveoles inside of a low permeable layer (e.g. clay) included between two layers with slightly higher permeability (e.g. limestone). Radioactive elements are leaking from their containers over a p...

Ancestral semi-natural meadows, locally called “Lameiros”, are an essential element of the mountain landscapes in Northern Portugal. These meadows are frequently located in areas of high water availability, loamy soils and over 700-800m hight. In association with these meadows can be found traditional irrigation systems, in which the water is applied all year around, to assure the crop water re...

In diesem Artikel wird ein Überblick über leichtgewichtige Kryptographie (lightweight Cryptography) gegeben. Weiterhin werden die beiden neuen auf Hardware optimierten Chiffren DESL und PRESENT näher vorgestellt. Der anschließende Vergleich der Implementierungsergebnisse mit anderen kürzlich vorgeschlagenen Blockchiffren wie mCrypton, HIGHT oder CLEFIA zeigt, dass DESL und PRESENT weniger Chipf...
