AIM The objective of study was to investigate the effects of drinking water on certain physiological parameters such as heart rate (HR), respiration rate (RR), rectal temperature (RT) and, ruminal motility (RM). MATERIALS AND METHODS The experiment was carried out on 18 farm bred lactating crossbred cows. The animals selected for the study were divided into three groups of six animals each on...
a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
Background and Objective: Human health depends on clean and safe drinking water more than anything. In Bilverdi Plain, the main source of drinking water is groundwater that has got a low quality in some places. Therefore, the drinking water of this area needs detailed evaluation of quality. In this research, the drinking water of Bilverdi Plain was evaluated based on fuzzy and deterministic met...
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...
background: the human body gets fluorine from a variety of sources including food and water. this element is essential in order to prevent tooth decay. however, high concentrations of this element led to a lot of dental fluorosis and skeletal injuries. this study aimed to measure the concentration of fluoride in water and tea consumed in the city of qom. methods: the present study is cross-sect...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: one of the goals of the world health organization (who) and world dental federation (wdf) is declining the decay, missing or filled teeth (dmft) index in people under 12 years down to the level of 1. the present study aimed to determine the dmft index in 7 to 11-year-old students and its association with the am...
conclusions the ppi-g2 dendrimer with end amine groups exhibited a positive impact on the removal of dominant bacterial isolated strains. therefore, it is possible to use these nanodendrimers as a safe and effective material for water disinfection in the future. results the most important isolated bacteria were escherichia coli 37 (48.7%), klebsiella oxytoca 12 (15.8%), proteus mirabilis 3 (4%)...
terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. this study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (go) thin layer to remove arsenic (v) from water. to fabri...
