The interaction of tranilast (TRN), an antiallergic drug with the main drug transporter in human circulation, human serum albumin (HSA) was studied using isothermal titration calorimetry (ITC), fluorescence spectroscopy and in silico docking methods. ITC data revealed the binding constant and stoichiometry of binding as (3.21 ± 0.23) × 10(6)M(-1) and 0.80 ± 0.08, respectively, at 25°C. The valu...
Shelf life prediction for liquid fuels depends on a reliable and efficient accelerated ageing method. Most of the available researches in this area are limited to isothermal ageing. Therefore, these isothermal ageing methods are not capable to predict shelf life for fuels at non-isothermal ageing conditions. In the previous work, a new approach called reaction severity index was proposed for t...
In this research, the TLP bonding of IN-738LC superalloy was investigated using MBF-20 amorphous foil produced by melt spinning process. The bonding process was carried out at 1035-1080°C for 30-60 min under the vacuum atmosphere. Microstructural investigations showed that the eutectic phases formed in non-isothermal solidified zone (ASZ) are consised of secondary phase borieds r...
the kinetics of molybdenite oxidation was studied by non-isothermal tga-dta with heating rate 5 ºc.min-1.the model-fitting kinetic approach applied to tga data .the coats-redfern method used for model fitting. the popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. the apparent activation energy was determined to be about 34.2 kcalmol-1 with pre-ex...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Isothermal and non-isothermal torrefaction characteristics and kinetics of microalga Scenedesmus obliquus (S. obliquus) CNW-N are studied using thermogravimetric analysis. The pyrolysis of S. obliquus CNW-N with increasing temperature is characterized by four-stage decomposition. Depending on the torrefaction temperature, light, mild, and severe torrefaction from the weight loss and the maximum...
in order to enhance the performance of interconnects which are used in solid oxide fuel cells (sofcs), a protective/conductive coating can be applied. in this research aisi 430 ferritic stainless steel was coated in a mn-base pack mixture by pack cementation method. in order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºc. electrical behavior was al...
