Effects Of Scenery, Lighting, Glideslope And Experience On Timing The Landing Flare, Stephen A. Palmisano, Simone K. Favelle, W L. Sachtler

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study examined 3 visual strategies for timing the initiation of the landing flare based on perceptions of either: (i) a critical height above ground level; (ii) a critical runway width angle (Y); or (iii) a critical time-to-contact (TTC) with the runway. Visual displays simulated landing approaches with trial-to-trial variations in glideslope, lighting, and scene detail. Twenty-four participants (8 private pilots, 8 student pilots and 8 non-pilots) were instructed to initiate the flare when they perceived that their TTC with the runway (30 m wide by 840 m long) had reached a critical value of 2 seconds. Our results demonstrated …

Bone Mineral Density And Content During Weight Cycling In Female Rats: Effects Of Dietary Amylase-Resistant Starch, Ian L. Brown, Hasina Ambia-Sobhan, Abigail E. Huang, Sue A. Shapses, Sugeet Jagpal, John D. Bogden, Francis W. Kemp, Anne M. Birkett

ABSTRACT: BACKGROUND: Although there is considerable evidence for a loss of bone mass with weight loss, the few human studies on the relationship between weight cycling and bone mass or density have differing results. Further, very few studies assessed the role of dietary composition on bone mass during weight cycling. The primary objective of this study was to determine if a diet high in amylase-resistant starch (RS2), which has been shown to increase absorption and balance of dietary minerals, can prevent or reduce loss of bone mass during weight cycling. METHODS: Female Sprague-Dawley (SD) rats (n=84, age = 20 weeks) …

After the enthusiastic celebration of the 20th Anniversary of the Montreal Protocol on Substances that Deplete the Ozone Layer in 2007, the work for the proctection of the ozone layer continues. The Environmental Effects Assessment Panel is one of the three expert panels within the Montreal Protocol.

Testosterone Effects On Avian Basal Metabolic Rate And Aerobic Performance: Facts And Artefacts, W A. Buttemer, S Warne, C Bech, Lee Astheimer

We examined the effects of cage size and testosterone (T) levels on basal and peak metabolic rates (BMR and PMR, respectively) and on pectoral and leg muscle masses of male house sparrows (Passer domesticus). Birds were housed either in small birdcages or in flight aviaries for at least 2 weeks prior to the initial metabolic evaluations. They were then implanted with either empty or T-filled silastic capsules and remeasured 5-6 weeks later. Birds treated with single T implants achieved breeding levels (4-6 ng/mL) and one group given double implants reached 10 ng/mL. There was no effect of T on BMR …

Effects Of Fully-Established Sure Start Local Programmes On 3-Year-Old Children And Their Families Living In England: A Quasi-Experimental Observational Study, Edward Melhuish, Jay Belsky, Alastair H. Leyland, Jacqueline Barnes

Faculty of Social Sciences - Papers (Archive)

Background

Sure Start Local Programmes (SSLPs) are area-based interventions to improve services for young children and their families in deprived communities, promote health and development, and reduce inequalities. We therefore investigated whether SSLPs affect the wellbeing of 3-year-old children and their families.

Methods

In a quasi-experimental observational study, we compared 5883 3-year-old children and their families from 93 disadvantaged SSLP areas with 1879 3-year-old children and their families from 72 similarly deprived areas in England who took part in the Millennium Cohort Study. We studied 14 outcomes—children's immunisations, accidents, language development, positive and negative social behaviours, and independence; parenting risk; …
