We have previously demonstrated a number of changes in the anterior lobe proopiomelanocortin (POMC) system in chronically stressed rats. The purpose of the present experiments was to investigate whether chronically stressed rats demonstrate changes in pituitary sensitivity to glucocorticoid negative feedback. To study this question we compared the effects of glucocorticoids on ovine corticotrop...

Fourier Transform Infrared (FT-IR) spectroscopy is a robust method for macromolecular analysis and differentiation of microorganisms. However, most studies are performed in controlled conditions and it is unclear whether this tool is appropriate for the identification of eukaryotic microalgae species from variable environments. In order to address this, nine closely-related species of marine an...

Abstract Reinforcement of the pre-stressed concrete cylinder pipes with external strands is an effective way to enhance a prestressed pipe’s ability bear design hydraulic pressure. A theoretical derivation studied, and this formula could be used determine cross-sectional area per unit length. This target tensile strength steel in order meet requirements ultimate limit states, serviceability qua...

net photosynthesis rate (pn), stomatal conductance (gs) and transpiration rate (e) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (tleaf), leaf vapor pressure deficit (vpd leaf) and photosynthetic photon flux density (ppfd) in well watered (ww), stressed (s) and recovered (r) plants. an analysis of measured data showed that...

Like that of many other Germanic languages, the stress system of Swedish has mainly undergone phonological analysis. Recently, however, researchers have begun to recognize the central role of morphology in these systems. Similar to the lexical specification of tonal accent, the Swedish stress system is claimed to be morphologically determined and morphemes are thus categorized as prosodically s...

RATIONALE Recent research suggests that chewing gum may improve aspects of cognitive function and mood. There is also evidence suggesting that chewing gum reduces stress. It is important, therefore, to examine these two areas and to determine whether contextual factors (chewing habit, type of gum, and personality) modify such effects. OBJECTIVES The aims of the present study were: (i) to dete...
