در این کار، اثر طول نانولوله کربنی بر یک سیستم جذب انرژی نانوسیالی با استفاده از شبیه سازی دینامیک مولکولی بررسی شده است. برای این منظور 6 طولnm 5، 6 nm، 7 nm، 8 nm، 9 nm و nm 10 برای هر یک از چهار نانولوله کربنی صندلی تک جداره صلب (8,8)، (10,10)، (12,12) و (14,14) انتخاب شده است. نتایج شبیه سازی ها نشان می دهد که در طول و قطر های مختلف نانولوله کربنی، سطح نانولوله کربنی بدون اصطکاک است که باعث...
Brown Norway rats (BN, BN/NHsdMcwi) are profoundly resistant to developing acute kidney injury (AKI) following ischemia reperfusion. To help define the genetic basis for this resistance, we used consomic rats, in which individual chromosomes from BN rats were placed into the genetic background of Dahl SS rats (SS, SS/JrHsdMcwi) to determine which chromosomes contain alleles contributing to prot...
Human small cell lung cancers (SCLC) produce and secrete the regulatory peptide bombesin (BN) or its mammalian counterpart gastrinreleasing peptide (GRP). In addition, several SCLC tumor lines have been shown to express high affinity receptors for BN/GRP. On the basis of these findings, we investigated the effect of exogenously added BN and GRP on the soft agarose colony growth of a panel of hu...
Background. Different studies indicate a high prevalence of eating disorders in athletes. These disorders represent a serious defect in many areas of life. Eating disorders can lead to changes in consumer or intake of food and significant damage to physical health and psychosocial sports performance. Objectives. The aim of the present study was examining the effects of Cognitive Behavior Thera...
در این تحقیق خواص مکانیکی نانوکامپوزیت پایه سیمانی تقویت شده با نانولوله های کربنی با روش میکرومکانیکال شبیه سازی شد. اثر پارامترهای مختلف مانند مدول سیمان، قطر داخلی نانولوله ها، قطر خارجی نانولوله ها، طول نانولوله ها، شکل المان انتخاب شده بر روی نتایج بدست آمده مورد بررسی قرار گرفت. در ادامه به منظور معتبر سازی این مدل، نتایج بدست آمده از مدل با نتایج تجربی محققان مختلف مقایسه شده است. نتایج ...
Density functional theory computations with dispersion corrections (DFT-D) were performed to investigate the dihalogen interactions and their effect on the electronic band structures of halogenated (fluorinated and chlorinated) BN bilayers and aligned halogen-passivated zigzag BN nanoribbons (BNNRs). Our results reveal the presence of considerable homo-halogen (FF and ClCl) interactions in bila...
Denote by B∗ n the set of all k∗-cycle resonant hexagonal chains with n hexagons. For any Bn ∈ B ∗ n , let m(Bn) and i(Bn) be the numbers of matchings (=the Hosoya index) and the number of independent sets (=the Merrifield-Simmons index) of Bn, respectively. In this paper, we give a characterization of the k∗-cycle resonant hexagonal chains, and show that for any Bn ∈ B ∗ n , m(Hn) ≤ m(Bn) and ...
The objective of this study was to determine a classification system for BN in incarcerated groin hernia patients and to explore the possible relationship between BN staging and patient outcomes. Incarcerated groin hernia patients treated with emergency bowel resection from January 2008 to December 2013 were screened for inclusion in a prospective study. A novel three-stage classification syste...
Let Ej be the eigenvalues outside [−2, 2] of a Jacobi matrix with an − 1 ∈ ` and bn → 0, and μ′ the density of the a.c. part of the spectral measure for the vector δ1. We show that if bn / ∈ `, bn+1 − bn ∈ `, then ∑ j (|Ej | − 2) = ∞, and if bn ∈ `, bn+1 − bn / ∈ `, then ∫ 2 −2 ln(μ′(x))(4− x) dx = −∞. We also show that if an − 1, bn ∈ `, then the above integral is finite if and only if an+1 − ...
Epoxy resin is one of the most widely used thermosetting polymers and commonly applied in power electronics field. The intrinsic properties epoxy can be improved by introduction inorganic filler, thus fabricating a composite material. In this paper, different scales modified boron nitride (BN, 1 ?m, 10 ?m) were to improve thermal conductivity resin. surfaces BN modification silane coupling agen...
