catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of n-methyl morpholine-n-oxide. under the same conditions, only the cis isomer reacted, leading to triol (3). the steric hindrance of the equatorial oh group probably prevents the trans isomer from entering into such reaction. triol (3) was also obtained from the reduction of the diol-...
The most promising applications for thermoacoustic cooling are investigated from the perspective of the thermodynamic second law efficiency in this paper. A design optimization program interacting with the thermoacoustic simulation program known as DELTAE was developed. Then it was applied to two of the most common configurations for standing-wave thermoacoustic coolers in order to determine th...
A deep-sea manganese nodules test miner has not only coupled relationship between system components but also various design requirements of each system to meet the specified multitasks. To accomplish the multiobjectives of complex systems, multidisciplinary design optimization MDO is performed.Metamodels such as the krigingmodel and the response surfacemodel are employed to reduce computational...
در این پژوهش با استفاده از روش تابع گرین غیر تعادلی و فرمولبندی لانداور- بوتیکر، در مدل بستگی قوی خواص ترابرد وابسته به اسپین از طریق مولکول پلی استیلن در فاز ترانس (trans-pa) متصل شده به دو الکترود فلزی با سطح مقطع محدود، بصورت عددی بررسی میشود. با مطالعه ترابرد همدوس وابسته به اسپین از طریق مولکول pa ، جریان و قطبش اسپینی را در دو حالت بدون حضور رادیکالهای آزاد (حالت پایه) و در حضور رادیکالها...
Background Social support and school play a pivotal role in the development of oral health-related behaviors among students. This study was conducted to determine the relationship between stages of dental cleaning behavior change based on Trans-theoretical model with school role and social support in Iranian students. Materials and Methods In a cross-sectional study, 525 male and female student...
Background and Importance: Abscess of the hypophysis or pituitary adenoma is a very rare entity, and its preoperative diagnosis could be challenging. The clinical presentation is less specific, and despite the recent advancement in imaging, diagnosis before surgery is still difficult. Case Presentation: We reported two cases of pituitary abscesses in patients aged 38 and 42 years. The first ...
