toxoplasmosis is an infection caused by the protozoan parasite toxoplasma gondii (t.gondii) throughout the world. although usually asymptomatic, the infection can cause serious medical problems in immunocompromised individuals and fetuses. toxoplasmosis also causes considerable economic loss because of abortion in livestock. dna vaccination is a promising approach against intracellular parasite...
objective(s): hypoxia is a serious challenge for treatment of solid tumors. this condition has been manifested to exert significant therapeutic effects on glioblastoma multiform or (who) astrocytoma grade iv. hypoxia contributes numerous changes in cellular mechanisms such as angiogenesis, metastasis and apoptosis evasion. furthermore, in molecular level, hypoxia can cause induction of dna brea...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
Introduction: There are some routine two-dimensional sequences, including short tau inversion recovery (STIR), T2-weighted fast-spin echo (T2W-FSE), and proton-density fast spin-echo for diagnosing osteoarthritis and lesions of the knee cartilage. However, these sequences have some disadvantages, such as long scan time, inadequate spatial resolution, and suboptimal tis...
in this paper we investigate a new notion of bases in hilbert spaces and similarto fusion frame theory we introduce fusion bases theory in hilbert spaces. we also introducea new de nition of fusion dual sequence associated with a fusion basis and show that theoperators of a fusion dual sequence are continuous projections. next we de ne the fusionbiorthogonal sequence, bessel fusion basis, hilbe...
فرآیندهای تکتونیکی، آتشفشانی و پیشروی عمومی دریای ائوسن در اقصی نقاط ایران، رخساره های رسوبی متنوعی را ایجاد کرده است. نهشته های سنگی ائوسن در ناحیه چیمه رود (شمال غرب نطنز) در موقعیت بینابینی زون ایران مرکزی و سنندج سیرجان شامل 660 متر سنگ های آتشفشانی، مخلوط هایی از سنگ های آذرآواری- کربناته، انواع توف ها و ماسه سنگ های آواری و مخلوط کربناته- آواری می باشد. کوهزایی لارامید سبب شده که این رسوب...
