سالهاست که انرژی زمین گرمایی، که از گرمای قسمتهای داخلی زمین حاصل می گردد، به صورت بخار یا آب داغ در تولید الکتریسیته، گرمایش و فرآیندهای صنعتی مورد استفاده قرار می گیرد. به طور کلی حوزه های زمین گرمایی به صورت یک سیکل دائمی گردش گرما و سیال هستند که سیال از حوزه های تغذیه یا به وسیله تزریق وارد منبع شده و از سوی دیگر به صورت آب داغ و بخار خارج می گردند و در حین بهره برداری صنعتی، سیال استفاده ...
this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
This study was carried out to determine heart rate (HR) values, including diurnal, seasonal, and sex patterns, in the African giant rat (Cricetomys gambianus, Waterhouse). HR was measured using stethoscope in grip-restrained African giant rats of either sex (103 bucks and 98 does), live-trapped from a tropical Savannah, and caged individually in the laboratory during the harmattan (cold-dry), h...
in process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight .the volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. drought stress and dehydrated root reduce. the volume of the pulp extract of 23 ml. the objective of this experiment was to determine the proper...
in order to recognize isfahan weather types, in this research 22 variables including temperature, precipitation, atmospheric humidity and wind were studied in isfahan synoptic station from dey,11th,1339(january,1st,1960) to dey,11th,1383 (december,31st,2004). a cluster analysis on the euclidean distance of standardized matrix of data and linking days on the basis of ward method showed that isfa...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Hypertension can be classified into HOT and COLD in Persian medicine. In HOT hypertension, cardiac output is increased which causes an increase in heart rate or stoke volume; therefore, treated with bloodletting (cold temperament), food such as barley is recommended. In COLD hypertension, blood viscosity or arterial sympathetic tone is increased which is usually associated with mental stress wh...
The modulating effects of ascorbic acid (AA), vitamin E (E), and a combination of AA and E (AA + E) against eight-hour road transportation stress were investigated in 120 pullets during the hot-dry season. The result obtained showed that handling, loading and transportation induced lymphopenia, neutrophilia, liveweight loss, and mortality, which was alleviated by oral administration of AA, E, a...
Recent evidence suggests that changes in atmospheric circulation have altered the probability of extreme climate events in the Northern Hemisphere. We investigate northeastern Pacific atmospheric circulation patterns that have historically (1949-2015) been associated with cool-season (October-May) precipitation and temperature extremes in California. We identify changes in occurrence of atmosph...
Abstract. Compound dry and hot conditions frequently cause large impacts on ecosystems societies worldwide. A suite of indices is available for the assessment droughts heatwaves, yet there no index incorporating joint variability at sub-monthly scale. Here we introduce a daily-scale index, called standardized compound drought heat (SCDHI), to assess dry-hot conditions. The SCDHI based daily (th...
