This study explored retention of idioms and novel (i.e. newly created or grammatically generated) expressions in English-speaking girls following exposure only once during a conversation. Our hypothesis was that idioms, because of their inherent holistic, nonliteral and social characteristics, are acquired differently and more rapidly than novel utterances. Two age groups of typically developin...
Liquid Chromatography Time-of-Flight Mass Spectrometry (LC-TOF-MS) is widely used for profiling metabolite compounds. LC-TOF-MS is a chemical analysis technique that combines the physical separation capabilities of high-pressure liquid chromatography (HPLC) with the mass analysis capabilities of Time-of-Flight Mass Spectrometry (TOF-MS) which utilizes the difference in the flight time of ions d...
The aim of this paper is to understand the need employee retention in IT industry India during time covid. Employee has ever been termed as complex phenomenon and always intrigued HR managers. sunrise industry. Post-liberalization, recorded significant growth which could not have possible without efforts human resources involved it. factors make employees stay organization are known factors. An...
Fluoride retention is high during fluoride supplementation and increases with increasing fluoride intake. When large amounts of fluoride were given for several months the retention of fluoride was about the same as in the initial phase of fluoride supplementation, whether the supplemental dose of fluoride was 10, 20, or 45 mg per day. The rapid return of the fluoride balance to control values...

The study aimed at investigating whether the retention of vocabulary acquired incidentally is dependent upon the amount of task-induced involvement. Immediate and delayed retention of twenty unfamiliar words was examined in three learning tasks( listening comprehension + group discussion, listening comprehension + dictionary checking + summary writing in L1, and listening comprehension + dictio...
Because people forget much of what they learn, students could benefit from learning strategies that yield long-lasting knowledge. Yet surprisingly little is known about how long-term retention is most efficiently achieved. Here we examine how retention is affected by two variables: the duration of a study session and the temporal distribution of study time across multiple sessions. Our results ...
background : to identify correlates related to retention time of a cohort study of the opioid-dependent patients participating in the methadone maintenance treatment (mmt) program offered by a major addiction treatment clinic in tehran, iran between april 2007 and march 2011. methods : several parametric survival models assuming weibull, log-normal and log-logistic distributions were compared t...
to examine how water retention characteristics in a landfill environment change as a result ofsolid waste settlement and to derive the evolution of pore size distribution, a lab scale long column experiment was carried out at two different time periods while keeping all the other characteristics constant. two columns, column 1 and column 2, were used in the study. the log normal distribution mo...
