Direct solar irradiance may cause thermal discomfort, even in winter when the ambient temperature is low and especially for high-altitude locations with a high intensity of solar radiation. Thus winter solar shading might be required and, if used, must achieve a balance between the prevention of the transmittance of solar irradiance, the utilization of passive solar heat and the supply of adequ...

The Mars Global Surveyor spacecraft was initially placed into a high eccentricity, nearly polar orbit about Mars with a 45-hour period. To accomplish the science objectives of the mission, a 2-hour, circular orbit was required. Using a method known as aerobraking, numerous passes through the upper atmosphere slowed the spacecraft, thereby reducing the orbital period and eccentricity. To success...

In contrast to the claim that the most significant fault line in contemporary global affairs is between the civilisation of the West and all others, this essay argues that the schism between those who advance their values through violence and those who rely on persuasion, both of which are present in all civilisations, is the greatest source of conflict in the post-Cold-War era. Moderates come ...

The implementation of dance studios in the community has a function as forum for non-formal education whose existence is currently growing and developing community. Today, there are many orientation not only scope social activities but become part business their implementation. This article aims to provide an overview management traditional Bandung-West Java area, Indonesia, concept orientation...

Eleonora's falcon (Falco eleonorae) is a rare raptor species that delays its breeding period until late summer to feed its young with passerines at the peak of autumn migration. Since the 1950s, this slender winged falcon has been believed to migrate along a historical route via the Red Sea to its main wintering area in Madagascar. In our study, we used satellite telemetry to investigate the re...

Solar concentrators offer good promise for reducing the cost of solar power. Planar waveguides equipped with a microlens slab have already been proposed as an excellent approach to produce medium to high concentration levels. Instead, we suggest the use of a cylindrical microlens array to get useful concentration without tracking during the day. To use only a seasonal tracking system and get th...

BACKGROUND/OBJECTIVE Patient-centred attitudes have been shown to decline during medical training in high-income countries, yet little is known about attitudes among West African medical students. We sought to measure student attitudes towards patient-centredness and examine validity of the 18-item Patient-Practitioner Orientation Scale (PPOS) in this context. PARTICIPANTS/SETTING 430 medical...

Introduction: Pit craters are circular to elliptical collapse features that commonly occur in alignments (chains) and that coalesce into troughs [1], [2], [3], [4], [5]. We have begun systematically mapping the regional distribution of pit chains in the western hemisphere of Mars using the Mars Orbiter Camera (MOC) data. Pit chains are most prominent in the Alba Patera region and along the Vall...

Entrepreneurial orientation as a concept has gained the attention of scholars over last decade. It also became interesting to find out its relationship with business performance in South-West Nigeria. This study set any measure influence that entrepreneurship well entrepreneurial may assert on medium size businesses, Nigeria sample location. The results showed pro-activeness (β = 0.145), compet...

We present near-infrared H2, radio CO, and thermal infrared observations of the nearby massive star-forming region Cepheus A (Cep A). From H2 bow shocks arranged along four distinct jet axes, we infer that the massive protostellar source HW2 drives a pulsed, precessing jet that has changed its orientation by about 45 in roughly 104 years. The current HW2 radio jet represents the most recent eve...
