2014 In this paper, we present the influence of some astronomical and constructive parameters on the HFT working. The astronomical parameters are : (1) hour and (2) day. The constructive parameters are : (3, 4) the east-west and north-south distances between heliostats, (5) the mirror size, (6) the tower height, (7) the distance between the tower and the heliostats field. The HFT working is ana...

OBJECTIVE To examine by hour of day and day of week the 750,000 compensation claims that were lodged by male workers in Queensland, Australia, during the 20-year period from 1968 to 1988, including an investigation into some possible reasons for the increased number of claims on Mondays and the reduced number of claims on Fridays. METHOD The study was based on the collection entitled Industri...

STUDY OBJECTIVE To determine the impact of sleep disordered breathing (SDB) in children on neurocognitive function 5 years later. DESIGN SETTING AND PARTICIPANTS A subgroup of 43 children from the Tucson Children's Assessment of Sleep Apnea Study (TuCASA) who had SDB (RDI ≥ 6 events/hour) at their initial exam (ages 6-11 years) were matched on the basis of age (within 1 year), gender and ethn...

Presynaptic release of glutamate into the extracellular compartment and activation of receptor-operated calcium channels may contribute to ischemic neuronal damage. We evaluated the effect of baclofen, a selective inhibitor of presynaptic glutamate release, on mortality, working memory, and light microscopic hippocampal and cortical damage in the four-vessel occlusion model of cerebral ischemia...

This research describes the result of study and analyze working process harvester combine with GPS receiver grain level sensor in wheat harvesting. showed that was what velocity real time regime how much being uploaded into tank. According to results when yield increased from 2.62 t/ha 6.22 t/ha, because decreasing work-velocity harvester, work efficiency decreased 1.96 ha/hour till 1.30 ha/hou...

Amultifunctional material, strontium zirconate, SrZrO3, studied in literatures as a dielectric ceramics, thermal barrier coating, proton-conductor, and luminescent material was sprayed by a water-stabilized plasma torch WSP 500. Stainless steel and plain carbon steel were used as substrates. Coatings with thickness of 1 to 2 mm were produced, whereas the substrates were preheated over 450 °C. T...

STUDY OBJECTIVES Burnout is a growing health problem in Western society. This study aimed to investigate sleep in subjects scoring high on burnout but still at work. The purpose was also to study the diurnal pattern of sleepiness, as well as ratings of work stress and mood in groups with different burnout scores. DESIGN Sleep was recorded in 2 groups (high vs low on burnout) during 2 nights; ...

As an introduction to the special issue, this article provides a common definition of phenomenon studied, i.e. zero-hour contracts, and sets out research goals pursued through successive contributions that compose it. Zero-hour contracts are long-term relationships where employer does not commit providing minimum number working hours worker. Legal scholars often state antithetical decommodifica...

Excessive land use and suburbanisation around densely populated urban areas has gone hand in hand with a growth in overall transportation and discussions about causality of traffic congestions. The objective of this paper is to gain new insight regarding the composition of traffic flows, and to reveal how and to what extent suburbanites' travelling affects rush hour traffic. We put forward an a...
