The aim of this study is to apprehend the function of the stone enclosures during the Neolithic and the Bronze Age. Some enclosures well positioned in the Corsican chronology have been chosen to show an evolution of their dimensions, of dry-stone techniques used and of the function of the structures excavated within enclosures. The results prove that during the Neolithic, the whole habitat is i...

PCB structures like traces couple to the cavity field inside of an enclosure. It has been presented before that the coupling of a trace inside of a homogeneous cavity is caused just by its vertical segments on the trace ends. For an inhomogeneous cavity, consisting of a FR4 PCB layer and an air layer, we show that a trace couples along its whole length. The different coupling must be considered...

Behavioral studies in non-human primates have become ideal models for further investigations into advanced cognitive function in humans. To date, there is no systematic ethogram of the cynomolgus monkey (Macaca fascicularis) in a free enclosure. In a field observation of 6012 subjects, 107 distinct behaviors of M. fascicularis were preliminarily described. 83 of these behaviors were then indepe...

Strontium (atomic symbol Sr) is a silvery-white alkaline earth metal that exists in several stable (e.g., Sr-86 and Sr-88) and several radioactive (e.g., Sr-89 and Sr-90) isotopic states. Stable strontium and its salts have many industrial uses, such as providing the red color in pyrotechnic devices such as tracer bullets, distress signal rockets, flares, and fireworks. In medicine, strontium b...

An increasing number of zoos keep their animals in natural-looking enclosures, but it is often unclear whether or not the species’ behavioural and ecological needs are being adequately met. For species that suffer predation in the wild, structural enrichment in captivity can play a crucial role in connection with enclosure use. Firstly, we examined the effectiveness of structural enrichment in ...

Heat dissipation, thermal stresses, size and cost are the key packaging design issues for electronic and optoelectronic instruments. As per defense requirement, instruments are expected to work satisfactorily in the temperature range of -30C to +55C. In this study, we have explored the thermal management of a sealed enclosure, envisaged as housing for handheld instruments, using different activ...

The intention of this article is to compare the containment performance of a Type II microbiological safety cabinet (MSC) confronted with the simultaneous generation of a saline nanoparticle aerosol and a tracer gas (SF(6)). The back dissemination coefficient, defined as the ratio of the pollutant concentration measured outside the enclosure to the pollutant flow rate emitted inside the enclosu...

Most portable diesel generators (often referred to as gensets) produce high sound power levels. The sound generated by various internal components of the genset is transmitted to the far field by two radiation mechanisms: sound transmits through the panels of the generator enclosure as well as propagates through any openings in the enclosure. In order to determine which mechanism to control, a ...

Contemporary design of large telescopes requires optimization of the telescope environment in order to fully realize the capabilities of advanced mirror technology, telescope control and instrumentation. Telescope enclosure design is a critical element in providing this optimized environment. Enclosures must protect the telescope while minimizing the local degradation of image quality, and the ...
