An in vitro assessment of the retentive behaviour of fissure sealants
Journal of Dentistry, 1976Abstract The transverse strengths and dimensional changes upon water immersion of three polymeric fissure sealants have been investigated. All three sealant materials expanded following water absorption, with Epoxylite 9075 showing the greatest amount of expansion and ESPE 71730 the least.

THYROID HORMONES AND THE ACQUISITION AND RETENTION OF BEHAVIOURAL RESPONSES
Endocrinology, 1989Naive rats placed in a plexiglass cylinder from a 15 minute test period show progressive immobility, and retain the immobile response when given a 5-minute retest 24 hours later. In the present study we show that hypothyroidism markedly attenuates the acquisition of the immobile response; that this effect on acquisition is reversed 5-10 minutes after ...

The thyroadrenal axis, food deprivation and retention of a behavioural response
European Journal of Pharmacology, 1993The effects of adrenalectomy on retention of the immobile response in the Porsolt swimming rat test are equally reversed by dexamethasone, ketocyclazocine and thyroxine; the effects of hypothyroidism are similarly equally well reversed by all three agents, or by adrenalectomy.

Modelling of UPLC behaviour of acylcarnitines by quantitative structure–retention relationships
Journal of Pharmaceutical and Biomedical Analysis, 2014In the present work, the retention time (RT) of acylcarnitines, collected by ultra-performance liquid-chromatography after formation of butyl esters, is modelled by quantitative structure-retention relationship (QSRR) method. The investigated set consists of free carnitine and 46 different acylcarnitines, including the isomers commonly monitored in ...

Leadership Behavioural Strategies for Employee Retention
2010All organisations or business enterprises of all sizes under all names are only to serve the needs of the people. All organisations are not only run by people, but also it is the people in it, i.e. more specifically employees, at various levels who determine the efficiency and effectiveness of the organization and thus their very survival especially in

Investigation of Retention Behaviour in Packed Column SFC
Berichte der Bunsengesellschaft für physikalische Chemie, 1989AbstractRetention behaviour in supercritical fluid chromatography (SFC) with packed columns was investigated using two model mixtures. Xanthine bases (caffeine, theophylline, theobromine) were chosen as a relatively polar group while fat‐soluble vitamins (vitamin A, vitamin D2, vitamin E) were taken as a mixture of lower polarity.

Prediction of retention behaviour of some phenolic antioxidants
Journal of Chromatography A, 1981Abstract The possibility of the prediction of retention behaviour was studied in reversed-phase liquid chromatography on a macroporous organic gel (Separon SE) with methanol-water as eluent. Linear dependences were found in the effect of the mobile phase composition on the retention of all the solutes tested. For the prediction of retention data in a

Assessment of water retention behaviour in compacted fills
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2011This paper presents the water retention behaviour of a fill used to build a flood protection embankment in Scotland. The water retention curve was obtained in the laboratory using three different techniques: high-range psychrometer, contact filter paper, and by interpreting mercury intrusion porosimetry data, to cover a relatively wide suction range ...

Parasites enhance self-grooming behaviour and information retention in humans
Behavioural Processes, 2014Self-grooming is a common behavioural strategy used by various animals to reduce parasite loads. We experimentally tested the adaptive significance of self-grooming model in a sample of Slovak participants. Propensity to self-grooming was activated by visual presence of parasites with verbal information about health risks caused by parasites suggesting

Long-term retention of behavioural habituation in the rat
Animal Behaviour, 1973Abstract The orienting response in rats was measured by the interruption in licking that occurred during the presentation of a tone stimulus. Habituation occurred after a mean of 6·3 presentations and there was complete retention of habituation for 72 hr, and 70 per cent retention after 288 hr.
