The incidence of neurodegenerative diseases are increasing in the present generation. Based on their diversified causes it is targeting almost all the age groups including young (juvenile) and old (senile) population without discrimination. There are some metabolic diseases which are targeting the brain functions in young. The juvenile diabetes is one among them, where the excess of unutilized glucose is following wide range of deranged paths resulting into encephalopathy. The early detection of such diseases needs to be identified and tackled at the earliest. The existing modern treatment is having much limitation; hence it is inviting the contribution from the field of alternate herbal medicine.

Leaching of plastic into hot tea from plastic cups
The present investigation was aimed to asses the amount of leaching plastic material, if any, into tea from disposable plastic cups. Fifty plastic cups were analyzed for the study, and thickness of cups was in the range of 70 – 90 µm (micron meter). The determination of leaching procedure was done through making difference in weight of used and unused cups through electronic weighing balance. First of all, weights of fresh unused cups were measured then measurements of weights of cups were taken after using hot tea. The tea was kept in cups for 10 minutes assuming that any person finishes tea after 10 minutes. The temperature of tea was measured 100°c at the time of serving. The weight of fresh unused cups and the weight of used served with hot tea cups were analyzed. The weight of used cups served with hot tea showed significant (P < 0.05) decreased in the weight as compared to fresh unused cups. The significant decrease in the weight of used cups showed the leaching of plastic material into tea. The results in this study indicated that the leaching of plastic material from cups into hot tea and the amount of plastic material leached was in the range of 1.5 – 2.0 mg per cup from < 1gram of cup.

Uzun Hasan’s Wives Founder of Ak Koynlu state(1425-1477)
At the age of thirty, Uzun Hasan took over Amed (Diyarbakir), the capital city of Ak Koynlu state and became the unrivaled ruler. He married his first wife at the age of fifteen; soon after, he married his second and third wives. His first wife was a Turcoman, the second was a Kurd and the third was a Christian. Each of the wives acted in accordance with the personalities, potentials, personal skills and the wills they possessed. The Turcoman queen or Seljuk Shah could not stand to lead a life away from the Ak Koynlu palace; thus she established a broad network of relations with the Ak Koynlu dignitaries and military leaders and also was an influential figure among the Ak Koynlu members. She was so skillful that she could easily gather Ak Koynlu family around herself. After her husband died, her role became even greater. Hasan’s Kurdish wife kept a low profile. Most of her decisions and wills were expressed by her son Ughrlu Mohammed. In factMohammed’s personality overshadowed his mother’s personality since she was not allowed to work within the palace. As for Hasan’s third wife, Dspina, the Christian, it is obvious that she married Hasan to protect Trabzon Empire ruled by her father. Then she started to influence Uzun Hasan to work against the Ottoman Empire. Furthermore, she played an active role in building relations between Hasan and the West, particularly the Venetian Republic.

Taken defensiv strategy of prioritizing the capacity of banks to earn fee income from providing services using analytic hierarchy process (Case Study: Bank Mellat)
Due to major changes taken place in the banking system of Iran, Bank Mellat has faced new challenges: restructuring state sectors into private ones through privatization, an increase in their rivals, the intense competition to obtain more market share, bringing about more expenses and costs as to four bank deposits, etc., has led the bank to tends to increase the commission (the income from services’ commission). In this paper, the researcher has collected the required information through interviews with experts as well as scientific and library studies.the purpose of this study is Taken defensiv strategy of prioritizing the capacity of banks to earn fee income from providing services using analytic hierarchy process. The analytic hierarchy process (AHP) is a structured technique for dealing with complex decisions that was developed by Thomas L. Saaty in the 1980 year. It provides a comprehensive and rational framework for structuring a decision problem, for representing and quantifying its elements, for relating those elements to overall goals, and for evaluating alternative solutions. The base of this model is comparing variables by pair wise by Matrix relationship. In this way, pair wise of the effective variables on the prioritizing the capacity of banks were considered and based on relative weights the output was extent. In the present research, combination of Indexing system Method with Analytical Hierarchy Process has been applied to assess the prioritizing the capacity of banks. By this process. The findings of the research show that the issue of fees based on the separation of non-shared with 0/179 point and Trying to customer satisfaction with 0/117 point are located in first and second rank.

The effect of teaching lexical collocations through concept mapping on receptive and productive knowledge of collocations among Iranian high school EFL learners
The present study is an attempt to explore the effect of concept mapping, as a learning strategy, on the receptive and productive knowledge of lexical collocations of Iranian high school EFL learners. It also explores whether teaching lexical collocations through concept mapping will be effective in terms of retention of lexical collocations or not. Sixty female Iranian third-grade high school students participated in this study. They were randomly divided into two homogeneous groups; control and experimental. In the experimental group, lexical collocations were taught through concept mapping, and in the control one, Persian translations of the same lexical collocations were provided. Both groups received 12 sessions of instruction by the researcher. Data analysis indicated a statistically significant difference between the receptive and productive knowledge of collocation of those learners who are taught lexical collocation through concept mapping and those who were taught traditionally. In other words, in terms of both receptive and productive knowledge, concept mapping strategy outweighed the traditional one in learning English collocations. However, there was no statistically significant difference between retention of receptive and productive collocational knowledge in the experimental group.

Reliability based design optimization of hollow shaft using integrated probabilistic response surface methodology
Classical reliability based design procedures require tedious calculations and time consuming. The goal of reliability of mechanical component adequately performs its intended function when operating under specified environmental conditions. Mechanical component design by safety factors using nominal values without considering uncertainties may lead to designs that are unsafe, or too conservative and thus not efficient. Design of a hollow shaft is one of complex and time consuming design procedure. This paper presents development of mathematical models to predict the outer diameter of a typical hollow shaft. This paper presents unique method to investigate engineering problem, its analysis, mathematical modeling and optimization with the help of RSM-response surface methodology and design of experiments (DOE). Response surface methodology, which is a statistical approach of design of experiments, is being applied with combined probabilistic design to optimize the design responses in the case of simultaneous variations of its design parameters. The technique is proved to be efficient and general purpose modeling a variety of components.

EFL Teachers’ Evaluations and Expectations about English Language Courses in Iranian Universities
The focus of this study is to explore EFL teachers’ evaluations and expectations about English language courses as EFL in Iran. In other words, this article aims at creating a new avenue for effective EFL teaching curriculum and syllabus in the Iranian context. Iranian universities offer basic, general, and specific English courses as a part of their program, which are not being very effective. These courses do not promote the students in dealing with their disciplines or programs oriented courses. Even after completion of these courses in three or more semesters, students fail to grasp comprehensive control over the reading materials of their field. This is a common scenario in almost all the universities in Iran. The authors of this paper ventured to study the predicament of EFL courses in some universities. The data were collected through questionnaires from a total of 40 EFL teachers at 8 universities. The research results revealed that the existing English Course syllabus is not tailored appropriately to the needs of the students. It, therefore, suggests that university English courses should be redesigned in assimilating the learners’ need, and course contents should cover the socio-cultural factors of the learners.
