abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
the aim of this study was the increasing of leachate quality using integrated membrane bioreactor (mbr). the reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the analysis of cod, biochemical oxygen demand (bod5), total suspended solids (tss), and total dissolved solids (tds) were performed in feed and filtrate, whenever the system reached steady stat...
the present study was carried out to evaluate three interpolation methods including weighted moving average (wma) with the power of 2 and 3, kriging and cokriging methods. data of 23 wells in mazandaran province were collected in fall and spring 2006. seven parameters including electrical conductivity (ec), ph, total dissolved solids (tds), sodium adsorption ratio (sar), total hardness (th), ch...
groundwater contamination is a serious problem facing the countries. because groundwater is vulnerable to contamination from a variety of sources, and, once contaminated, it is very difficult to restore to its original quality. the main objective of this study was evaluation of groundwater quality in shahrekord aquifer and finding the source of the groundwater contamination. some of the chemica...
study of groundwater quality trend in any region is very important from the view of scheduling and sustainable water resources management. in the present study trend analysis conducted on groundwater quality based on information of 32 piezometeric stations located in the ardabil plain from 1993 to 2008 using the non-parametric spearman test. hydrogeochemical variables studied here are total ani...
One of the most serious problems affecting coastal aquifers is seawater intrusion. Senegal currently facing an increased demand for freshwater resources due to population growth and economic development in areas. In areas affected by saltwater contamination, chloride concentrations as high 8880 mg/L were measured groundwater samples taken from wells near zone, indicating deterioration water qua...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
the purpose of this two-phase, sequential mixed methods study was to find out whether there were any decencies between male and female ma students’ theses regarding the common features of academic writing such as syntactic complexity, means of integrating cited information, and organizing arguments. i chose 10 male written theses and 15 female written theses in tefl and linguistics. in the firs...
the aim of this study is to examine the difference between the introverts and extroverts in preferred advice-giving style. furthermore, it explores the difference between l1 (persian) and l2 (english) regarding the giving of advice for the extroverts and introverts separately. it investigates whether an extrovert or introvert gives advice in the same manner in his l1 (persian) and l2 (english) ...
In the rubber dam's impact area, the groundwater total hardness (TH) has declined since 2000, ultimately dropping to 100-300 mg/L in 2012. pH levels have shown no obvious changes. NH4-N concentration in the groundwater remained stable from 2000 to 2006, but it increased from 2007 to 2012, with the largest increase up to 0.2 mg/L. NO3-N concentration in the groundwater generally declined in 2000...
