Measurements of TR yield and spectra for a large variety of regular radiator configurations have been presented by different authors. In general, data confirm the theoretical predictions [1], although total TR yield and dependence on the momentum of the emitting particle are not always reproduced [2][3]. The ALICE Transition Radiation Detector (TRD) consists of 540 drift chambers with mixed fib...

conclusions atpl was higher in the post-monsoon season. w/s ratio and correlation analysis revealed interseasonal homogeneity of tmv and traffic noise levels and interseasonal heterogeneity of air pollutant concentrations and atpl in the city microenvironments. results atpl was 3.35 times higher in the post-monsoon and 1.83 times higher in the pre-monsoon season than the permissible limits pres...

During long-term low-flow sevoflurane anesthesia, dew formation and the generation of compound A are increased in the anesthesia circuit because of elevated soda lime temperature. The object of this study was to develop a novel radiator for carbon dioxide absorbents used for long durations of low-flow sevoflurane anesthesia. Eleven female swine were divided into two groups comprising a "radiato...

Large modern sports stadia are often multifunctional buildings that are not only used for sports purposes but also for other events such as concerts, conferences and festivities. Some of the stadia that have been built in recent years in north-western Europe are equipped with a semi-transparent roof that can be opened and closed, depending on the weather conditions and on the type of event. Whe...

The influence of the improvement finned tube radiator unit structure on fluid flow and heat transfer effect locomotive was studied. A saw-toothed fin with aluminum instead copper proposed to keep position size flat hot water pipe unchanged. CFD simulation analysis carried out by ICEPAK17.0, under conditions an ambient temperature 24.6 °C, atmospheric pressure 85,040 Pa air density ? = 0.94 kg/m...

A roof provides protection to be safe from direct sunlight. From the shelter, shadow alone is not expected. Durability, sustainability, less life cycle cost, and low maintenance cost are expected from a selected roof. The world has a thirst to have a best roof. No roof will fulfil the requirement of humanity since the climatic conditions are different. Hence the roof should be selected accordin...

The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

A ring-imaging Čerenkov counter, to be read out by four 100channel PMT’s, is a key element of the BRAHMS Experiment. We report here the most recent results obtained with a prototype tested at the BNL AGS using several radiator gases, including the heavy fluorocarbon C4F10 . Ring radii were measured for different particles (π−, μ−, e−) for momenta ranging from 2 to 12 GeV/c employing pure C4F10 ...

Increasing urban albedo can reduce summertime temperatures, resulting in better air quality and savings from reduced air-conditioning costs. In addition, increasing urban albedo can result in less absorption of incoming solar radiation by the surface-troposphere system, countering to some extent the global scale effects of increasing greenhouse gas concentrations. Pavements and roofs typically ...

In order to measure the longitudinal phase-space profile of the electron beam, we are developing a compact measurement system consisting of a Cherenkov radiator, a bending magnet and a streak camera. The Cherenkov radiator with an aerogel is installed in the beam transport line, and the electron distribution in the longitudinal phase-space is obtained. Furthermore, a slice emittance measurement...
