Conceptual problems of unified two-nucleon force models are discussed. The force models are based on the pion-nucleon vertex and attempt a description of the nucleon-nucleon interaction below and above pion threshold. The conceptual problems arise from the nucleon renormalization due to pionic degress of freedom. Keeping channels with a single pion only no renormalization procedure can be given...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
Purpose: Many research studies reported balance disorder as one of the most important consequences of Functional Ankle Instability. However, the Balance Recovery Strategy, which its deficiency can cause poor balance or secondary damages, has not been investigated in previous studies yet. The purpose of this article is to study the Balance Recovery Strategy in athletes with Functional Ankle Inst...
در این پروژه، ابتدا تولید کربن فعال از باگاس به روش فعال سازی شیمیایی با اسید فسفریک بررسی گردید. عوامل موثر بر تولید کربن فعال شناسایی گردیده و سه عامل مهم نسبت آغشتگی با اسید فسفریک، دمای فعال سازی و زمان فعال سازی برای بررسی بیشتر انتخاب شدند. با استفاده از روش طراحی آزمایش های تاگوچی، میزان تاثیر این عوامل بر کیفیت کربن فعال تعیین شده و شرایط بهینه برای تولید کربن فعال از باگاس مشخص شد. کرب...
Background and purpose: Balance impairment is a major cause of falls in patients with hemiplegic stroke. The purpose of this study was to compare the effects of two balance training programs in these patients. Materials and methods: A clinical trial with pretest–posttest design was conducted in 30 patients after a single hemisphere stroke that occurred at least 6 months before the stud...
Of the 82.5 million inhabitants in 2003, 3.4 million lived in the formerly divided capital of Berlin, another 13.5 million lived in the 5 Länder succeeding the former GDR, situated in the eastern part of the country, and 66.6 million lived in the old FRG, situated in the western part. From 1993 until 2003, the share of elderly above 65 years increased from 15% to 18%; the share of elderly above...
