the static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. to do so, the wires are austenitized at different temperatures and cooled in different rates. then the wires are drawn and aged at a specific temperature and time. before and after aging of each...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
The basic need of living things that is very important and cannot be separated water. Various industrial activities require water for processing such as the palm oil industry, industry required to use with good conditions proper chemical treatment. power plant at PT. Socfindo Seunagan, requires steam needs from boiler. Boiler a closed place produce heating boiler system, among others, consists ...
Background: This retrospective study aimed to investigate the physicochemical properties of drinking water sources in Ethiopia and compare the water quality with the health-based target. For this purpose, the water quality database of Ethiopian Public Health Institute (EPHI) from 2010 to 2016 was used. Methods: The concentration and other properties of the water samples were analyzed according...
The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...

The present study was made with an attempt to produce yogurt by partial addition of different levels soymilk cow milk. Control prepared 100% milk and other samples in the ratio 95:5, 90:10, 85:15, 80:20, 75:25 respectively. control treatments blends were analyzed for total solids pH. results found that leads increase pH from 6.7, 11.94 % 7.1 12.54 containing 25:75 Yogurt some physicochemical an...
