‎ Introduction: Controversial results have been reported about the effect of morphine and stress on learning and spatial memory in rodents. There are very few studies about the effects of ultra low doses of morphine on memory. In this study, effects of acute administration of low and usual doses of morphine on memory formation and retention in the presence and absence of repeated stress w...

a new parametric model was developed for predicting cut point of hydraulic classifiers. the model directly uses operating parameters including pulp flowrate, feed particle size characteristics, pulp solids content, solid density and particles retention time in the classification chamber and also covers uncontrollable errors using calibration constants. the model applicability was first verified...

OBJECTIVES To investigate mortality in men admitted to hospital with acute urinary retention and to report on the effects of comorbidity on mortality. DESIGN Analysis of the hospital episode statistics database linked to the mortality database of the Office for National Statistics. SETTING NHS hospital trusts in England, 1998-2005. PARTICIPANTS All men aged over 45 who were admitted to NH...

The present paper aimed to study the effect of pairwise video check feedback (including the observation of external pattern of skill performance and performing the skill simultaneously) on the learning on acquisition and learning of eye-hand coordination skill. Computer skill of eye-hand coordination skill was the tool used in this study. 24 subjects were randomly selected and equally divided...

Most algorithms for identifying peptides from tandem mass spectra use information only from the final spectrum, ignoring non-mass-based information acquired routinely in liquid chromatography tandem mass spectrometry analyses. One physiochemical property that is always obtained but rarely exploited is peptide chromatographic retention time. Efforts to use chromatographic retention time to impro...

This study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among Iranian EFL learners through immediate uptake and retention. Five classes were randomly categorized into four experimental groups and one control group, each with 18 in...

in biological wastewater treatment large quantities of sludge are produced. this sludge is highly putrescible.for disposal and safe usage should be stabilized. the anaerobic digestion is a standard technique for stabilization. due to the rate imiting step of sludge hydrolysis, anaerobic degradation is a slow process with high digestion time. due to high retention time and sludge dewatering prob...

it is crucial to monitor the growth and development of a child in early stage of life to take early corrective action in time to ensure normal growth. child health card (chc) is a tool used to maintain records and monitor the under five children. the objective of this study was to find out the maternal awareness on chc and factor associated with its retention. this was a cross sectional analyti...
