An extensive study of Fischer-Tropsch synthesis (FTS) on alumina-supported cobalt catalysts with different amounts of cobalt is reported. Up to 40 wt % of cobalt, is added to the catalysts by impregnation method. The effect of the cobalt loading on the reducibility of the cobalt oxide species, dispersion of the cobalt, average clusters size, water-gas shift (WGS) activity and activity and s...
In the present paper, an experimental assessment was performed on the transient thermal performance of a heat sink filled by a phase change material (PCM) and PCM embedded with carbon nanofibers (CNFs) and titania (TiO2) nanoparticles as nanostructured materials. In order to enhance the thermal conductivity of PCM, CNFs and TiO2 nanoparticles at different loadings (0.5wt. % and 2 wt.% of CNFs a...
In this study, a Fe-based amorphous metallic coating (AMC) was sealed with three sealants, i.e., stearic acid, aluminum phosphate and cerium salt, respectively. Two types of electrochemical tests, namely the ex situ impedance spectroscopy test in potentiostatic polarization test, were conducted to evaluate erosion–corrosion resistance as-sprayed as-sealed AMCs. The results show that phosphate–s...
The mol wt of the glycoprotein(s) carrying the PLA1 antigen was examined on platelets, megakaryocytes and endothelial cells by immunoblotting with a human polyclonal anti-PLA1 antibody (BE), as well as on four different monoclonal antibodies (MoAbs; DEK-1, DEK-2C, DEK-10, and DEK-16) raised against GPIIIa, the 100,000-mol wt platelet glycoprotein known to carry the PLA1 antigen. BE reacted with...
We consider the identification of a Markov process {Wt, X ∗ t } for t = 1, 2, ..., T when only {Wt} for t = 1, 2, ..., T is observed. In structural dynamic models, Wt denotes the sequence of choice variables and observed state variables of an optimizing agent, while X∗ t denotes the sequence of serially correlated unobserved state variables. The Markov setting allows the distribution of the uno...
To better understand the numerous solutions related to watershed transform (WT), this paper shows the relationships between some discrete definitions of the WT: the watersheds based on image foresting transform (IFT), topographic distance (TD), local condition (LC), and minimum spanning forest (MSF). We demonstrate that the tie-zone (TZ) concept, that unifies the multiple solutions of a given W...
The effect of sudden changes of water temperature (WT) on the survival rate and physiological responses of the red spotted grouper (Epinephelus akaara) were examined by manipulating WT control system for 9 days. Experimental condition was divided in two different regimes at low (from 10°C to 4°C, decreased 1℃/d) and high (from 28°C to 34°C, increased 1°C/d) WT. Survival rate of experimental fis...

در این کار تجربی لایههای نازک اکسید ایندیم آلاییده با اکسید قلع (ITO) با ترکیبهای مختلفی از 60 تا wt%95 اکسید ایندیم و 40 تا wt%5 اکسید قلع با استفاده از روش تبخیر با باریکه الکترونی بر روی زیرلایههای شیشهای نهشته شدند. لایهها پس از نهشت، به مدت 3 ساعت در هوا در دمای Cْ450 تحت عملیات حرارتی قرار گرفتند. تاثیر غلظت آلاینده اکسید قلع با تغییر غلظت آن از 5 تا wt%40 بر روی خواص ساختاری و اپتیک...
In order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. Silver-oil nanofluid prepared by Electrical Explosion of Wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. The average size...
