Radiation damage is an important factor that must be considered while designing nuclear facilities and nuclear materials. In this study, radiation damage is investigated in graphite, which is used as a neutron reflector in the Tehran Research Reactor (TRR) core. Radiation damage is shown by displacement per atom (dpa) unit. A cross section of the material was created by using the SPECOMP code. The concentration of impurities present in the non-irradiated graphite was measured by using the ICP-AES method. In the present study the MCNPX code had identified the most sensitive location for radiation damage inside the reactor core. Subsequently, the radiation damage (spectral-averaged dpa values) in the aforementioned location was calculated by using the SPECTER, SRIM Monte Carlo codes, and Norgett, Robinson and Torrens (NRT) model. The results of “Ion Distribution and Quick Calculation of Damage”(QD) method groups had a minor difference with the results of the SPECTER code and NRT model. The maximum radiation damage rate calculated for the graphite present in the TRR core was 1.567 9 10^-8 dpa/s. Finally, hydrogen retention was calculated as a function of the irradiation time.

太阳是自然界许多能源的主要来源。太阳能可以直接用于许多方面,其中最重要的是:供暖、照明、水加热、冷却、蒸汽生产、海水淡化和热能发电。太阳能是一种可持续发展的绿色能源,可供广泛使用。在本论文中,我们研究了约旦的太阳能以及发展太阳能系统的最突出的障碍和途径。我们研究了政府发展该领域的计划,以及这些政策在发展可再生能源领域中的有效性。我们还讨论了近年来中国的经验,如何以及成功的原因,并试图找到约旦可以如何从中国的经验中受益。借鉴包括中国在内的太阳能利用成果丰富国家在太阳能可持续性方面的经验,合理利用太阳能。有一些可能的措施:(1)由于太阳能应用的重要性和在支持国民经济方面的作用,需要对这一课题进行了大量的研究。(2)培训约旦太阳能部门的人员如何合理利用太阳能。(3)吸引中国太阳能专家赴约旦开展太阳能的可持续性利用工作,并借鉴他们的经验。(4)约旦政府应促进各太阳能应用部门的合作,加强它们之间的伙伴关系。(5)支持中小项目,普及利用太阳能的重要性。(6)利用长期贷款为可再生能源项目提供资金,并把这些资金用在正确的方向上。最后为推动约旦太阳能热水系统的使用,本论文为约旦某住宅设计了一套太阳能热水系统,并利用TRNSYS软件建立了数值仿真模型研究,通过数值模拟分析了该系统的运行性能。数值模拟结果表明,该太阳能热水供暖系统的太阳能保证率较高,说明该系统具有良好的运行性能,且适用的最佳角度是31°。本文的研究结果将有助于约旦太阳能应用的发展。

ObjectiveThis systematic review aimed to analyze animal and human trial data to better understand the efficacy of stem cell therapy (SCT) for erectile dysfunction (ED) and the obstacles that may hinder its application in this *** searched electronic databases, including PubMed and Scopus, for published studies with the Medical Subject Heading terms of “erectile dysfunction” (AND) “stem cell therapy” (OR) “erectile dysfunction” (AND) “clinical trial of stem cell therapy” (OR) “stem cell therapy” (AND) “sexual dysfunction”. The search was limited to English-language journals and full papers only. The initial search resulted in 450 articles, of which 90 relevant to our aims were included in the *** is a multifactorial disease. Current treatment options rely on pharmacotherapy as well as surgical options. Patients may have side effects or unsatisfactory results following the use of these treatment options. SCT may restore pathophysiological changes leading to ED rather than treating the symptoms. It has been evaluated in animal models and shown promising results in humans. Results confirm that SCT does improve erectile function in animals with different types of SC use. In humans, evidence showed promising results, but the trials were heterogeneous and limited mainly by a lack of randomization and the small sample size. Many challenges could limit future research in this field, including ethical dilemmas, regulation, patient recruitment, the cost of therapy, and the lack of a standardized SCT regimen. Repairing and possibly replacing diseased cells, tissue, or organs and eventually retrieving normal function should always be the goals of any therapy, and this can only be guaranteed by *** is a potential and successful treatment for ED, particularly in patients who are resistant to the classic therapy. SCT may promote nerve regeneration and vascular cell regeneration, not only symptomatic treatment.
