Induction of Chondrogenic Differentiation of Human Adipose Mesenchymal Stem 1 β-Cell with TGF
Adult stem cells which are derived from different tissues,with their unique abilities differentiate in to various phenotypes have the potential for cell therapy.The purpose of this study was the Induction of Chondrogenic Differentiation of Human Adipose-Derived Stem Cell with transforming growth factor -β1. human adipose mesenchymal stem cells were extracted and was amplified through several passages. Passage 3 cells were treated with chondrogenic medium,after 11 days, in the presence of inducing differentiation into cartilage were planted at the end of the term ,RT-PCR were used. In the present study, the isolated cells in terms of morphology, were fibroblast Based on. the results of RT-PCR, genes such as aggrecan and type II collagen in cultured chondrocytes differentiate into…

Interval TOPSIS method for ranking Casting parts supplier of Tabriz Tractor Manufacturing Company
Sometimes in the real world we are faced with the data occupying on interval for which providing the exact value for them is hard and complicated. Therefore, when we want to rank such data we need to use advanced decision making methods. In the conventional decision making, the developed TOPSIS method for interval data as one of the classical methods of multiple criteria decision making is important. In this paper we are going to concentrate both on ranking and selecting appropriate suppliers for cooperation in supplying parts of Tabriz Tractor Manufacturing Company based on interval data in order to avoid unnecessary expenses which are usually incurred for the company.Important criteria for the evaluation and ranking of suppliers of Tractor Manufacturing Company determined by library…

LMI Based Nonlinear Observer Design for Estimating Tire-Road Friction Force
This paper deals with the problem of the robust tire-road friction force estimation. Tire-road friction is the most important piece of information used by active safety system. The friction coefficient between the tire and the road is exactly the kind of information which is very useful but is not directly measurable. To achieve the vehicle speed information and tire-road adhesion property is very important to the vehicle active safety control system. Since the friction is the main mechanism for the production of friction in the car, accurately describes the friction force generated at the interface between road and tire is very important and there are different methods for modeling tire road friction force. In this paper we propose structure a new nonlinear observer using linear matrix…

Mineralogy, Environmental Geochemistry and Health Effects of the Khuzestan Dust, SW Iran
Recently the Khuzestan province in southwest of Iran is affected by duststorm phenomena and makes some problems in agriculture, Transportation, Communication and human health side effect in this province. Mineralogy, Geochemistry of particles and Geo- Environmental characteristics of trace elements is very important for detecting of major pollutant. The collected dust samples were analyzed for grain size, mineralogy, and chemical composition. The dust is predominantly Aluminosilicates (clay minerals and feldspars), quartz and carbonates with minor amounts of gypsum. The particles are mostly sub-rounded to sub-angular and generally between 5 to 02 μm in size. XRD studies show that calcite and quartz are the major constituents in most samples, and clay minerals such as Illite and…
On the simulation and application of Generalized Weighted Weibull Distribution
The new class of weighted exponential (WE) distributions obtained by Gupta and Kundu (9002) applying Azzalini’s method to the exponential distribution. .Kharazmi, at, al (9012) extended weighted exponential distribution to the generalized weighted exponential(GWE) distribution and studied its different properties. In this study we generalize the weibull distribution to a new class of generalized weighted weibull (GWW) distribution. Several statistical and reliability properties of this new class of distribution are obtained. Estimation and inference procedure for distribution parameters are investigated. Finally, we show that the proposed model can provide better fit than recent class of weighted exponential by using two real data examples…

Optimization of preparation of Insulin nanoparticles composed of quaternized aromatic derivatives of chitosan using artificial neural networks
The aim of this research was to develop an artificial neural network (ANN) in order to design a nanoparticulate oral drug delivery system for insulin. The pH of polymer solution (X1), concentration ratio of polymer/insulin (X2) and polymer type (X3) are considered as the input values and the particle size, zeta potential, PdI, and entrapment efficiency (EE%) as output data. ANNs are employed to generate the best model to determining the relationships between input and response values. In this research, a multi-layer percepteron with different topologies has been tested in order to define the one with the best accuracy and performance. The optimization was used by minimizing the error between the predicted and observed values. Three training algorithms (Levenberg –Marquardt (LM),…
Opial’s Condition and Fixed Point for Nonexpansive Mapping in Banach spaces
Opial’s condition plays an important role in the study of weak convergence of iterates and random products of nonexpansive mappings and of the asymptotic behavior of nonlinear semigroups. In this paper, we prove the weak convergence of a modified Noor iteration for nonself I- nonexpansive mapping in a Banach space which satisfies Opial’s condition. Finally a fixed point theorem for multivalued nonexpansive mappings in a Banach space satisfying this condition is proved….
Optimization of sustained release delivery Olanzapine system
The objective of this study is to develop controlled release formulation of water insoluble Olanzapine (OZ), using Glycerol monooleate (GMO) and Polyethylene glycol (PEG 300). A Box-Benkhen response surface methodology was applied to design gel system with 3 factors with an initial drug containing within the range of 2-4%, weight ratio of GMO/water (w/w) in the range of 2-4% and weight ratio of PEG 300/GMO (w/w) in the range of 2-6%. Dependent variables include entrapment efficacy (EE %), percentage of release at 12th and 168th hr and viscosity. A quadratic model as an appropriate equation has been selected to fit the entrapment efficacy (EE %). Percentage of release at 12th and 168th hr and for viscosity a cubic model is selected. Optimization of liquid crystalline phase was carried out…
QSAR modeling of Indole derivatives for treatment Multiple Sclerosis’s diseases
In this research we have studied the quantitative relationship between structure-activity(QSAR) on derivations of indole and 7aza indole as anti-MS drug compounds. Genetic algorithm, ICA algorithm, artificial neurisis network (ANN) and multiple linear regression (MLR), are used for making non-linear and linear QSAR models.
