Zinc transporter (ZnT1) mRNA is differentially expressed in vivo, in weaned pig tissues, and in vitro, in response to additions of zinc sulphate or antibiotics. Summary Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in ZnT1 mRNA in a porcine jejunal epithe-l...

Agents are of interest mainly when confronted with complex tasks. We propose a methodology for the automated design of such agents (in the framework of Markov Decision Processes) in the case where the global task can be decomposed into simpler -possibly concurrentsub-tasks. This is accomplished by automatically combining basic behaviors using Reinforcement Learning methods. The main idea is to ...

Virtual environments have a variety of uses, ranging from entertainment to simulation of hard-to-create environments for training and testing purposes. A common feature of virtual environments, especially those aimed at entertainment, is the presence of virtual entities we call agents, characters or objects in the virtual world possessing human characteristics and able to interact pro-actively ...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...

A new molecularly imprinted polymer for extraction of crocin from saffron stigmas was prepared using gentiobiose (a glycoside moiety in crocin structure) as a template. Crocin binding to gentiobiose imprinted polymer (Gent-MIP) was studied in comparison with a blank nonimprinted polymer in aqueous media. Affinity of the Gent-MIP for the crocin was more than the nonimprinted polymer at all conce...
