In this research, effects of changes in aluminizing conditions on microstructure of Pt - aluminide coating applied oil a Ni - base superalloy GTD -111, has been studied. A thin layer (i.e.68,#mm ) of Pt was electroplated onto the surface of the .samples, and then they were aluminized by pack cementation technique under various conditions of time, temperature, rate of heating and pack powder com...
Background: In previous studies, we reported that green tea decoction (GTD) cooked in boiling water for 15-min (15-min GTD) reduced body weight gain (BWG), glucose and lipid absorption and improved total antioxidant status (TAS) of rats fed normal or high-fat diet (HFD). However, the long-term effect of a mixture: 15-min GTD + lemon juice (LJ) on BWG, liver steatosis (LS), TAS, blood glucose an...
PURPOSE The objective of this study was to assess the predictive role of the neutrophil/lymphocyte ratio (NLR) for invasion of gestational trophoblastic disease (GTD). MATERIALS AND METHODS A retrospective analysis was conducted on 127 women who were managed at our clinic for GTD. Of all patients, 8 showed invasion according to histological examination. The clinical parameters of patients wit...
The actin-activated ATPase activity of full-length mammalian myosin Va is well regulated by Ca2+, whereas that of truncated myosin Va without the C-terminal globular tail domain (GTD) is not. Here, we have found that exogenous GTD is capable of inhibiting the actin-activated ATPase activity of GTD-deleted myosin Va. A series of truncated constructs of myosin Va further showed that the entire le...
Gestational trophoblastic neoplasia (GTN) is highly chemosensitive and has a high cure rate. Since the introduction of chemotherapy, reliable measurement of human chorionic gonadotropin (hCG) levels, and individualised risk-based therapy into the management of GTN, almost all low-risk and more than 80 % of high-risk GTN cases are curable. However, approximately 25 % of high-risk GTN developed r...
به منظور بررسی رفتار تغییرشکل گرم سوپرآلیاژ ریختهگری GTD 111 آزمایشهای فشار گرم در محدوده دمایی °C 1100- 950 و سرعت کرنش های 1-s 1- 001/0 انجام شدند. تمامی منحنیهای سیلان افزایش نسبتاً خطی تنش تا یک نقطه پیک و سپس نزول آن تا کرنش 5/0 را نشان دادند و منطقه تغییرشکل حالت پایدار با تنش ثابت مشاهده نشد. این روند به مهار نابجاییها توسط ساختار دندریتی و تکثیر آنها در نقطه پیک تنش نسبت داده شد...
This paper presents GTD-POP, a planning methodology based on the Generate, Test and Debug paradigm. GTD-POP’s goal is to achieve a compromise between planning efficiency and soundness by using associational knowledge to guide its search for interaction checks in a partially-ordered plan. This paper describes the GTD-POP and discusses issues involved in evaluating the behavior of practical plann...
In turbine engines, high temperature components made of superalloys may crack in a creep process during service. With the inward flux of the gases, e.g. oxygen and nitrogen, along those cracks, the microstructure of the superalloy substrate nearby the cracks may degrade by internal oxidation and nitridation. The aim of this study is to investigate and simulate the oxidation-nitridation-induced ...
