2) Suppose that Γ is a 4-paradoxical group and Γ = A1∪A2∪B1∪B2 is a paradoxical decomposition as defined above. Show that Γ plays ping-pong on itself, where the pingpong players are a := a−1 1 a2 and b := b −1 1 b2 .Deduce that Γ contains a non-abelian free subgroup F2. 3) Define the Tarski number T (Γ) of a group Γ to be the smallest integer N if it exists such that Γ is N -paradoxical. By the...
دریاچه ارومیه یکی از بزرگترین و مهم ترین اکوسیستم های آبی در ایران می باشد. با توجه به افزایش دما، تغییرات زیاد در بارندگی و همچنین وقوع خشکسالی در سطح حوضه، تراز آب دریاچه دچار تغییرات زیادی شده است. در این تحقیق تغییرات تراز سطح دریاچه ارومیه ناشی از تغییر اقلیم براساس مدلhadcm3 از سری مدل های گردش عمومی جو (gcm) تحت سناریوهای گازهای گلخانه ای (b2 و a2) با استفاده از شبکه های نرو فازی (anfis)...
abstract this study aimed at investigating the translation of interjections from english into persian in dubbing. to carry out this study the expressive secondary interjections found in the film four weddings and a funeral and their equivalent in persian dubbed version were analyzed through the strategies proposed by cuenca. the descriptive analysis of the corpus showed that (strategy b) i.e...
abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
Let T = (T∗, T△) be a spherical latin bitrade. With each a = (a1, a2, a3) ∈ T ∗ associate a set of linear equations Eq (T, a) of the form b1 + b2 = b3, where b = (b1, b2, b3) runs through T ∗ \ {a}. Assume a1 = 0 = a2 and a3 = 1. Then Eq (T, a) has in rational numbers a unique solution bi = b̄i. Suppose that b̄i 6= c̄i for all b, c ∈ T ∗ such that Supported by grant MSM 0021620839 Supported by Edu...
The statistical downscaling tool of a model (SDSM) to generate the future climate piedmont plain area in Hebei Province for 30-year period. Xinji city was selected as typical example this area. crop growth decision support system agrotechnology transfer (DSSAT) adopted estimate changing trends water footprint winter wheat production under conditions, and obtain optimal irrigation scheme an ‘acc...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
The present study investigated the simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). After being pretrained and tested on two symbolic match-to-sample tasks (X1-Y1, X2-Y2), 20 4- and 5-year-old children were trained to emit specified responses to pairs of stimuli (A1-R1, B1-R1, A2-R2, B2-R2) in one se...
در این مطالعه، روند تغییرات شاخص خشکی (AI)، تبخیر و تعرق مرجع (ET0) و بارش طی دوره‌های 2010-1966، 2040-2011، 2070-2041 و 2100-2071 در شش ایستگاه سینوپتیک غربی و شمال غربی ایران مطالعه شد. بدین منظور خروجی‌های مدل اقلیمی HadCM3 تحت سناریوهای انتشار A2 و B2 به روش آماری به‌وسیله مدل Statistical downscaling model (SDSM) ریزمقیاس سازی شد. به‌منظور روندیابی تغییرات شاخص خشکی، بارش و تبخیر و تعرق م...
