conclusions the established method has an acceptable performance in quantifying yb-1. in addition, serum yb-1 may aid in the diagnosis of hcc. results the developed method was linear to 150 μg/l of yb-1 with a minimum detection limit of 0.01 μg/l. the average recoveries were between 93.9% and 109.0%. the mean intra- and inter-assay coefficients of variation (cvs) were 4.0-4.8% and 8.2-10.2%, re...

n-methylol dimethyl phosphonopropionamide (mdpa) is one of the most utilized fire resistant (fr) finishes for cotton fabrics, utilized as part of a formulation with trimethylol melamine (tmm) to acquire better crosslinking and enhanced fr properties. the system parameters of the finishing treatment were upgraded for better fr properties and low mechanical loss to the fabric by the response surf...

The purpose of this research is predicting the stock prices using the Particle Swarm Optimization Algorithm and Box-Jenkins method. In this way, the information of 165 corporations is collected from 2001 to 2016. Then, this research considers price to earnings per share and earnings per share as main variables. The relevant regression equation was created using two variables of earnings per sha...

investigating the parameters influencing the behavior of buried pipelines under dynamic loading is of great importance. in this study the soil structure interaction of the pipelines with the surrounding soil was addressed using shaking table tests. wave propagation along the soil layers was also included in the study. the semi infinite nature of the field was simulated using a laminar shear box...

most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...

this study a novel high performance liquid chromatography for the assay of nystatin in oral and vaginal tablets were optimized and validated using box–behnken experimental design. the method was performed in the isocratic mode on a rp-18 column (30 °c) using a mobile phase consisting of 0.05 m ammonium acetate buffer/ methanol mixture (30:70) and a flow-rate of 1.0 ml/min. the method was valida...

introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...
