To create a highly efficient photovoltaic-thermal (PV-T) system and maximise the energy exergy efficiency, this study aims to propose an innovative configuration of PV-T comprising wavy tubes with twisted-tape inserts. Following validation numerical model, parametric has been conducted assess geometrical effects twisted tape tubes, as well coolant fluid type velocity, on overall performance sys...
– Stage 2. Triacastela-Sarria (440 m above sea level). We walked toward Samos for 18.6 kilometers, avoiding the first 4 kilometers that run parallel to the road because they required reaching the top of a peak at kilometer 4.7 and had difficult sections for the support vehicles. We felt that the next section, Sarria-Portomarín, was inappropriate, with too many parts unsuitable for vehicular tra...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
Glacial polish, grooves, and striations discovered at an elevation of 1370 meters in the headwaters of Boone Fork on Grandfather Mountain, North Carolina, indicate the former, existence of alpine glaciation at a latitude of 36 degrees 07'N. The Boone Fork glacier was located 890 kilometers south of the previously recognized southern limit of alpine glaciation in the Appalachian Mountains, and 3...
BACKGROUND Thermophilic campylobacters, particularly Campylobacter jejuni and C. coli are the main agents of human campylobacteriosis. Campylobacter contaminated chicken products is the most important source of foodborne gastroenteritis. Evaluation of genetic diversity among Campylobacter population is critical for understanding the epidemiology of this bacterium and developing effective contro...
the aim of this study was to identify the problems of translating markedness structures from english to persian in order to look closely at what possible difficulties translators may face. it also seeks to probe the strategies applied accordingly by iranian translators in translating them. from three translation of blindness novel, the sentences with marked structures were elicited and also the...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
Background and objectives: Vegetation is one of the most important elements of an ecosystem, which is directly related to the moisture conditions of the land. Estimation of plant drought indices such as VCI, TCI, VHI is an effective tool to assess the effects of drought by calculating NDVI. In this regard, several studies have been conducted that explain how to calculate and use these indicator...
This article presents a distributed real-time control system for the southern grid of the Cameroon power system. The southern grid, which supplies over 90 % of the power output in Cameroon, incorporates two remotely located hydro-electric generating stations, a power distribution center, several thermal plants and hundreds of kilometers of transmission lines. The proposed distributed control sy...
A circular crater, about 4 kilometers in diameter and located at 24.2 degrees N, 26.4 degrees E, was discovered in Landsat images among the linear dunes of the Great Sand Sea, Egypt. The crater has a sharp and crenulated rim crest, a terraced wall, a discontinuous inner structure (approximately 1.6 kilometers in diameter), and a few rim blocks. Its morphological and morphometric characteristics...
