The objective of this study was to determine the central effect of the VT4R antagonists (SR-49059 and H-5350 (Manning compound)) on corticosterone (CORT) levels during stress and food intake. A 22-gauge stainless steel guide cannula was surgically implanted into the lateral ventricle of the birds. A preliminary study was done to test the antagonists and their role on food intake. Birds were inj...

RÉSUMÉLa gestion des courbes de tarage stations hydrométriques affectées par la végétation aquatique saisonnière est une gageure. La croissance puis le déclin plantes font varier relation hauteur-débit continuellement dans temps, sorte qu’il difficile d’établir série temporelle débits du cours d’eau. À notre connaissance, il n’existe pas modèle courbe adapté à un contrôle chenal végétalisé. Dan...

Even though both fluid mechanics and numerical studies have considerably progressed in the past decades, experimental knowledge remains an important tool for studying resistance to flow media where a complex environment dominates pattern. After comprehensive review of recent literature on drag coefficient open channels with emergent rigid vegetation, this paper presents results related 29 accel...

In terms of the hydraulic effect plant flexibility, particular note is calculation formula that was proposed by Kouwen, which combines roughness riverbed with community parameter MEJ (including modulus elasticity). Kouwen’s method developed on basis laboratory experiments low vegetation (grasses). According to authors this work, can also be used evaluate resistance medium (shrubs) deforming und...

Closed-end furrows are commonly used to irrigate crop in northern part of China. The irrigation performance of furrow in this area is often low. The objectives of this paper are to verify reliability of infiltration parameters and Manning roughness estimated with SIPAR_ID software and present an optimized method for design of closed-end furrow system. The study consisted of field experiments an...

Limitations that humans impose on task execution are rarely integrated into simulations of complex systems, often resulting in loss of outcome fidelity. In this paper we discuss how discrete-event simulation has been used to model the impact of human interactions in U.S. Navy and Coast Guard programs. These models of planned U.S. Navy and U.S. Coast Guard vessels have been used to estimate crew...

RNA is highly sensitive to the ionic environment and typically requires Mg(2+) to form compact structures. There is a need for models capable of describing the ion atmosphere surrounding RNA with quantitative accuracy. We present a model of RNA electrostatics and apply it within coarse-grained molecular dynamics simulation. The model treats Mg(2+) ions explicitly to account for ion-ion correlat...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values, we scan also the right hand of each subject. We study how the ratio of the length of the index and ring fingers (2D:4D) of the right hand, a measure of prenatal hormone exposure, is correlated with bidding behavior and total profits. 2D:4D has been reported to predict competitiveness in ...
