objective: radiochromic ebt3 film is a later generation of radiochromic films. the aim of this study is to compare ebt and ebt3 radiochromic films in radiotherapy fields of breast cancer. methods: a rando phantom was irradiated by a 6 mv siemens primus linac with medial and lateral fields of radiotherapy of breast cancer. dosimetry was performed in various points in the fields using ebt and ebt...
This paper is a partial summary of the survey paper [1]. In particular, we are interested in telling the following story: given a lattice polytope, P , one would like to find an efficient way of counting the lattice points contained in P . One of the nicest ways to accomplish this is to use algebraic geometry in a clever and beautiful way. Namely, from P one can construct a toric variety, XP , ...
in this study two indices of tempo and quantum of fertility for the city of tehran are calculated. the tables are based on data which have been collected in a survey in 1986. the sampling was administrated at two stages. at the beginning 158 geographical points were considered (the number of first birth order during 24 hours in tehran), then on the first stage 17 random geographical points were...
Given a curve Γ⊂C with specified regularity, we investigate boundedness and positivity for certain three-point symmetrization of Cauchy-like kernel KΓ whose definition is dictated by the geometry complex function theory domains bounded Γ. Our results show that S[ReKΓ] S[ImKΓ] (namely, symmetrizations real imaginary parts KΓ) behave very differently from their counterparts Cauchy previously stud...
Background and Aim:To assess of human force and population's programming at high level, is very important that we know rates and characteristics of population. Growth of population has direct relationship with fertility rate of women in community. To control of population and arrive to index of N.R.R.(Net reproduction rate) equal to one ,each family must be has one or tow children .Thus ,in fa...
abstract: the present thesis includes ; one preface and 11speeches , that each speech considered in different researches . the prefact part , studied grammer back ground , the first speech considered a brief description about grammatical credits . the second speech considered the different typs of sentences , from structure and meaning points of view . the third speech considered the verb es...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
A bstract We study the massless Dirac field on line in presence of a point-like defect characterised by unitary scattering matrix, that allows both reflection and transmission. Considering this system its ground state, we derive modular Hamiltonians subregion given union two disjoint equal intervals at same distance from defect. The absence energy dissipation implies existence phases, where eit...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
