The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...
CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration .The optimum condition ...
In this paper, the fuzzy matrix equation $Awidetilde{X}B=widetilde{C}$ in which $A,B$ are $n times n$crisp matrices respectively and $widetilde{C}$ is an $n times n$ arbitrary LR fuzzy numbers matrix, is investigated. A new numerical procedure for calculating the fuzzy solution is designed and a sufficient condition for the existence of strong fuzzy solution is derived. Some examples are ...
sensitivity of tomato fruit to low temperature and chilling injury limits the storage, handling and marketability of the fruit. as a recommended postharvest treatment, effects of hot water treatment (hwt) on reducing chilling injury and quality traits, variation of tomato fruits during storage life were investigated. tomato fruits were harvested at mature green stage. they were treated by hot w...
introduction: educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. this study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students’ viewpoint and ultimately increase the awareness and understanding of authorities an...

Objective: This study was planned to investigate whetherCoriandrum sativum (C. sativum) is capable of protecting neurons against glucose/serum deprivation (GSD)-induced cytotoxicity. Material and Methods: The PC12 cells were cultivated for 24 h in standard media (high-glucose DMEM containing Fetal Bovine Serum) or for 6 h in GSD condition (glucose-free DMEM, without serum) in the absence or pr...
in this article, we study the artin-rees property in c(x), in the rings of fractions of c(x) and in the factor rings of c(x) . we show that c(x)/(f) is an artin-rees ring if and only if z(f) is an open p-space. a necessary and sufficient condition for the local rings of c(x) to be artin-rees rings is that each prime ideal in c(x) becomes minimal and it turns out that every local ring ...

A facile and efficient synthesis of bis(indolyl)methanes derivatives (3a-u) was reported via a condensation reaction of aldehydes and indole in the presence of by silica-supported-3-(triethoxysilyl) propane-1-ammonium chloride catalysis under solvent free conditions. We studied the reaction in different conditions and optimized. The use of just 0.02 g of (silica gel-ammonium salt) is sufficient...
