On analysis and evaluation of natural inspired computational models for open learning systems
Nature Inspired Computation defined as a computational intelligence paradigm inspired from natural biological systems (such as human brain and neural systems, Genetic Algorithms; Bees and Ants Colonies Optimization, etc........). Recently, this paradigm has been successfully applied for solving computational optimization problems, in many fields (such as, machine learning, and engineering design, etc.........). Moreover, by considering its unique computational intelligence characters of self-adaptive, self-organizing and self-learning. It is relevant to adopt its application for modeling and performance evaluation of educational Systems. Herein, the presented work motivated by recent research publications inspired by two interdisciplinary computational intelligence Models. Both have been characterized by challenged bridging of two Natural inspired Models across an interesting practical educational issue. More specifically, this piece of research concerned with the theoretical analysis and evaluation of constructive bridges of Artificial Neural Networks (ANNs) & Ant Colony Systems (ACS) across Open Learning Systems. Noting that motivating research publications include the following two topics: 1- Assessment of students' adaptability using ANNs models (Cognitive Styles Approach). 2- Modeling of Cooperative e-Learning Performance (ACS Approach).

Opportunities and challenges in bio treatment of industrial waste water
Microorganisms have a tremendous influence on their environment through the transfer of energy, charge, and materials across a complex biotic mineral–solution interface. The bio-modification of mineral surfaces involves the complex action of microorganism on the mineral surface. The manner, in which bacteria affect the surface reactivity and the mechanism of adsorption and accumulation of the primary data in this area are only starting. Bio-Processing involves the selective removal of undesirable mineral constituents from an ore through microbe-mineral interactions in the processes such as selective flotation and flocculation. At the same time, bio-sorption has made a considerable progress in moving from theory to industrial practice as it is not only environmental useful but also more economical than many other processes. The bio-flotation, bio-flocculation and bio-sorption processes concern the mineral response to the bacterium presence, which is essentially interplay between microorganism and the physicochemical properties of the mineral surface, such as the atomic and electronic structures, the net charge/potential, the acid–base properties, and the wettability of the surface. The adhesion of microorganisms to minerals result in alteration of surface chemistry of minerals relevant to beneficiation process due to a consequence of the formation of a biofilm on the surface or bio-catalyzed surface oxidation or reduction products. There is an urgent need for developing basic knowledge that would underpin biotechnological innovations in the natural resource processing technologies that deliver competitive solutions.

Pheochromocytoma revealed by acute coronary syndrome: A case report
Pheochromocytomas are catecholamine producing tumors arising mostly from chromaffin cells of the adrenal medulla. The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, It has been called 'the great mimic’, capable of presenting itself as many other medical conditions. The most common clinical presentation is hypertension, mainly in the form of paroxysmal episodes. Cardiovascular manifestations include malignant arrhythmia and catecholamine cardiomyopathy, mimicking acute coronary syndromes and acute heart failure. We report a case of pheochromocytoma revealed by angina, and acute myocardial infarction without coronary artery disease (CAD).

Phytate Hydrolysis in Chicken’s BBMVs: Influence of Age, Intestinal Site and pH
Age effect, intestinal site and pH influence on phytate hydrolysis were assayed in brush border membrane vesicles isolated from chicks and layers proximal and distal intestinal segments using MgCl2 precipitation and differential centrifugation. The ascertained BBMVs purity and functional integrity depicted alkaline phosphatase enzyme marker to range between 20-fold to 37-fold greater for chicks’ and layers’ proximal and distal BBMVs than in their mucosal homogenates, their integrity suggestive to presence of Na+-dependent transport while electron micrograph showed a vesicular form. Both chicks’ and layers’ BBMVs, had significant decrease in phytate-P hydrolysed/mg.

Prediction of Orange Orchards Output in Northern Region of Iran using Artificial Neural Network Model
In this study the energy consumption of orange orchards was surveyed and various Artificial Neural Networks (ANNs) developed to estimate the farmer’s production in the Sari region as a case study. The data were collected using a face-to-face questionnaire method from 86 farmers in the Sari region. The results indicated that the total amount of energy input and output were 54284.8 and 59223.4 MJ ha-1, respectively. Among all inputs involved, diesel fuel had the highest energy values per hectare. Also, energy efficiency, energy productivity and net energy were calculated as 1.09, 0.57 kg MJ-1 and 4938.5 MJ ha-1, respectively. Performance of developed ANN models were evaluated using the coefficient of determination (R2), mean absolute error (MAE) and root mean squared error (RMSE). The resulting tests showed that best performance was achieved by a momentum training algorithm resulting in R2=0.84, and MAE= 0.32 and RMSE=0.38 with 8-4-1 topology. Additionally, sensitivity analysis revealed that fertilizer and electricity energy had the highest and the lowest sensitivity on output, respectively.

Presenting New Solution for Optical Waves in Nonlinear Systems
There are lots of nonlinear formulas in mathematics and physics and there are, many types of solitons to talk over. This revision is dedicated to the straight technical particulars of how to produce soliton solution of Maxwell's equations and intensive confirmation is placed on mathematical report analysis. The quasi-stationary state waveguides has been founded and with a small deviation from equilibrium, we measured and advanced a solution for a formula. Classical parting of parameters is presented with a special B.C. is introduced on a slab waveguide to obtain a general form of solution of the coordinates x, y z.

Prime labeling of complete tripartite graphs K_(2,m,n) and K_(3,m,n)
Let G be a graph with n vertices. Prime labeling of G is the labeling of the vertices using first n positive integers such that labeling of each pair of adjacent vertices are relatively prime. This work is a generalization of [2] which was analogous to [1] in which prime labeling for complete bipartite graphs were considered. In [2] conditions for the existence of prime labeling of complete tripartite graphs of the form K_(1,m,n) was given where m,n?Z^+. In our work, we have proved that prime labeling of K_(2,m,n) and K_(3,m,n) exists for some values of m and n where m,n?Z^+. Further, few non-existance cases have been discussed.

Psychosocial responses among infertile womens and normal womens
Infertility has a strong and negative impact in several areas of the individual’s life. The infertile women may lose prestige in society, may develop a low self-esteem, and may lose hope for the future. This study compared psychosocial responses in 90 infertile women and normal women. An ex post facto design was used. The subjects of the present study were infertile women in an infertility treatment center in ,ahwaz, Iran. Women selected by randomly sampling. The women completed the Psychosocial responses. Data were analyzed using analysis of variance. Differences were found between the groups on the Psychosocial responses (self-image/self-esteem, guilt/blame, sexuality problems, and interpersonal relationship).

Reactive Power Control with Fuzzy Controller Based STATCOM
Flexible AC Transmission Systems (FACTS) play a major role in controlling the load flow in the power system. In this paper, reactive power control is performed with STATCOM based on the fuzzy controller. The purpose of using the fuzzy controller is to improve the STATCOM performance for continuous and fast reactive power control. The performance of the STATCOM based fuzzy controller in a 14-bus test system with simulation is evaluated by MATLAB/SIMULINK software. Also, a control component to limit STATCOM's reactive power at level of nominal power is used to prevent damage. The simulation results will show the optimal performance of the fuzzy controller and the limiter.
