Optimising the design of aviation propulsion systems using computational fluid dynamics is essential to increase their efficiency and reduce pollutant as well noise emissions. Nowadays, within this optimisation phase, it possible perform meaningful unsteady computations various components a gas-turbine engine. However, these simulations are often carried out independently each other only share ...
the mathematical properties of nano molecules are an interesting branch of nanoscience forresearches nowadays. the periodic open single wall tubulene is one of the nano moleculeswhich is built up from two caps and a distancing nanotube/neck. we discuss how toautomatically construct the graph of this molecule and plot the graph by spring layoutalgorithm in graphviz and netwrokx packages. the sim...
Congenital heart disease (CHD) has a complex genetic etiology, and recent studies suggest that high penetrance de novo mutations may account for only a small fraction of disease. In a multi-institutional cohort surveyed by exome sequencing, combining analysis of 987 individuals (discovery cohort of 59 affected trios and 59 control trios, and a replication cohort of 100 affected singletons and 5...
Endocannabinoids and some phytocannabinoids bind to CB1 and CB2 cannabinoid receptors, transient receptor potential vanilloid one (TRPV1) receptor and the orphan G protein receptor fifty-five (GPR55). Studies using C57BL/10 and C57BL/6 (Cnr2 (tm1Zim)) CB2 cannabinoid receptor knockout mice have demonstrated an immune-augmenting effect in experimental autoimmune encephalomyelitis (EAE) models of...

wiener index is a topological index based on distance between every pair of vertices in agraph g. it was introduced in 1947 by one of the pioneer of this area e.g, harold wiener. inthe present paper, by using a new method introduced by klavžar we compute the wiener andszeged indices of some nanostar dendrimers.
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
در این مطالعه، 40 نفر از مراجعه کنندگان به بخش پریودونتولوژی دانشکده دندانپزشکی مشهد که مبتلا به generalized chronic periodontitis بودند، انتخاب شدند. بیماران فوق به صورت تصادفی به دو گروه 20 نفری مورد و شاهد تقسیم شده و برای هر گروه بعد از انجام جرم گیری و تسطیح سطح ریشه، شاخص های plaque index (pi)، gingival index (gi)، شاخص bleeding on probing (bop) و عمق پاکت (pd) در چهار ناحیه شامل مزیوباکا...
پایان نامه، علاوه بر معرفی تبدیل سریع فوریه برای قیمت گذاری اختیار، فرمول قیمت گذاری اختیار دیگری از حاصل جمع فرمول بلک-شولز به دست می آوریم. برای مقایسه دو فرمول قیمت گذاری، داده های بازار s&p 500 index را کالیبره می کنیم. این کالیبره کردن به ما اجازه می دهد تا خصوصیات مدل و رفتار قیمت گذاری در مدل هستون را ارزیابی کنیم.
in this paper pi, szeged and revised szeged indices of an infinite family of ipr fullereneswith exactly 60+12n carbon atoms are computed. a gap program is also presented that isuseful for our calculations.
