different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
biosystematics of three-toed jerboas, genus jaculus (erxleben, 1777) (dipodidae, rodentia) from iran
the genus jaculusis distributed in palearctic desert and semi-desert areas, extending from central asia to the western sahara in the north africa. in iran three species of three-toed jerboa have been reported: jaculus jaculus from the south west and west of iran, jaculus blanfordi from the northeast, east and central part of iran and jaculus thaleri from the east of iran. in present study, the ...
genus rattus from the subfamily murinae has a wide geographical distribution throughout the world. three species of this genus have been reported in iran so far. they are norway or brown rat (rattus norvegicus), black rat (rattus rattus), and himalayan rat (rattus pyctoris). in order to verify the possibility of using electrophoretic patterns of special proteins, in biosystematic analysis of th...
An analysis of eight microsatellite loci in 90 individuals was performed to define the genetic structure and variability of three estuarine populations of Coilia mystus: 30 individuals each collected from ChangJiang River (Yangtze River) estuary-CJ, MinJiang River estuary-MJ, and ZhuJiang River (Pearl River) estuary-ZJ. The results showed polymorphic information contents (PIC) of 0.7...
Abstract Yellowfin seabream (Acanthopagrus latus), an important economical species and popular market fish found in the coastal water of Persian Gulf. In this study, eight microsatellite loci were used, population structure and genetic diversity of this species was studied in six fishing area in the Persian Gulf. Alleles observed in different stations were between 7 to 12 with an average of 9...
Factors governing large-scale spatio-temporal distribution of microorganisms remain unresolved, yet are pivotal to understanding ecosystem value and function. Molecular genetic analyses have focused on the influence of niche and neutral processes in determining spatial patterns without considering the temporal scale. Here, we use temporal phylogenetic analysis calibrated using microfossil data ...
This study was conducted to compare the morphometric and meristic characters and biological parameters including length-weight relationship parameters and condition factor comparison of Urmia bleak (Alburnus atropatenae) from Mahabad-Chaie, Ghale-Chaie and Gedar-Chaie rivers of Lake Urmia basin. A total of 20 morphometric and 7 meristic traits were measured. Morphometric data was standardized ...
Experiments were conducted to evaluate the response of different originated (the same mother plants with different growers from different cities in Ethiopia) cut rose flowers to various relative humidity (RH) and recut (recut and non-recut). Three different experiments (E1, E2 and E3) using three RH (60, 75 and 90%) and three Ethiopian growing areas (Fleur, Liki and Longonot) with 10 replicatio...
