In Silico Study of Salt Tolerance in Wheat and Related Species
Adenike Oluwatoyin Fujah
The in silico study of genes is an important step because it helps guide the interpretation of experimental results and suggest new experiments. Salinity tolerance comes from genes that limit the rate of salt uptake from the soil and the transport of salt throughout the plant, adjust the ionic and osmotic balance of cells in roots and shoots, and regulate leaf development and the onset of senescence. Salt-tolerant candidate genes in wheat and other cereals include HKT, NHX, SOS, and HAK genes. These genes were searched, identified and downloaded from the NCBI database. Comparative studies and analyses such as search for candidate genes’ functions, protein domains, multiple sequence alignments, and phylogenetic tree construction as well as primers design were carried out using bioinformatic tools. The RT-PCR primers associated with the candidate genes for the studied trait were designed as molecular markers for selection to assist the program for improvement in cereals.

Analyse Fréquentielle Des Maxima Annuels de Pluies Des Stations Synoptiques du Bénin et Élaboration des Courbes IDF à Cotonou
Ague I. Alain and Afouda Abel
In these recent years, many West African large cities have experienced unusual flooding. Appropriate rainfall information is one of the most important tools needed for hydraulic works necessary to mitigate or adapt to these climatic risks. The aim of this study is to analyze frequencies of extreme rainfall in Benin and build up the Intensity-Duration-Frequency curves for precipitation recorded at Cotonou station. The survey is performed for duration from 6 to 72 hours combining quantiles from daily rainfall data and data recorded from raingauges. Two statistical law (GEV and Gumbel) have been used. The choice of the best model has been made by numerical comparison. Five empirical models were used to build up the IDF curves of precipitations. These are Montana, Talbot, Keifer-Chu models and two new models introduced for this study and representing a general form of Talbot model and a generalized form of Keifer-Chu model respectively. Comparison between the first three well known models shows the predominance of Gumbel law on GEV law and inefficiencies of Montana model. For Cotonou station, the model of Keifer-Chu shows the best results especially when the combination of quantiles from daily rainfall data and data recorded from raingauge is made. This is confirmed and improved by the two newly introduced empirical models. Clearly Montana model usually adopted by civil engineer in Benin do not guarantee security of hydraulic works at Cotonou and should be changed for more suitable model leading to more sustainable management of flood risks in the present context of climate change.

Yaghob Gholami, Zinat Ansari, Mahdi Kazemi and Saeid Fereidouni
This paper is done to suggest a much more reliable method to forecast earnings using of data mining. Most studies in this area of research are based on the statistical and econometric models, which might encounter difficulties when dealing with the nonlinearity of financial data. Although data mining has already proved to be successful in many business applications, little research has been done on integrating financial statements' analysis with its techniques. This study utilizes Multi-layer Perception (MLP) and Radial Basis Function (RBF) techniques. In this way, it examines eight features of income statement of companies listed in Tehran Stock Exchange from 2005 to 2010. The results shows that MLP and RBF approaches respectively demonstrate about 80% and 82% efficiency of classification rate.
Keywords: Earnings forecasting, Multi-layer Perception, Radial Basis Function.

A Novel Approach for the Fuzzy Flow Shop Scheduling Problem with Setup Time to Minimize the Rental Cost
Shakeela Sathish and K. Ganesan
Production scheduling is an important task with the objective of minimizing the make span and the total cost in manufacturing systems. In this paper we discuss a fuzzy flow shop scheduling problem in which the concept of fuzzy setup time is introduced in addition to fuzzy processing time. By using a new type of fuzzy arithmetic and a fuzzy ranking method, we propose a new method to minimize the rental cost of machines under the specified rental policy; without converting the fuzzy processing times and fuzzy setup times to classical numbers. A numerical example is provided to illustrate the proposed method.
Keywords: Triangular fuzzy number, fuzzy ranking, fuzzy arithmetic, rental policy, fuzzy setup time, fuzzy processing time, fuzzy flow shop scheduling
Assessment of Health System Performance: Time- Trend of Avoidable Deaths during 2004-2011. A Case in Iran
Habib Omranikho, Abolghasem Pourreza, Abbas Rahimi Foroushani, Hassan Eftekhar Ardebili and Feyzollah Akbari haghighi
Background: Developing a comprehensive indicator for measuring the status of population health has always been challenging. Avoidable mortality is a useful approach invented and evolved with the aim of mitigating the challenge.
Objectives: we aimed to track the trend of avoidable and unavoidable mortality rates in order to measure the contribution of health system on population health in Bushehr province.
Methods: A list of avoidable causes of death was mainly constructed with regard to Nolte and McKee’s work with some exceptions. All deaths happened during 2004-2011 were studied. Age-standardized rates by sex for both avoidable and unavoidable conditions were calculated by using direct standardization method. The total causes of deaths during 2004-2011 were divided into four categories: 1-Treatable causes 2- preventable causes 3- ischemic heart disease (IHD) and 4-unavoidable causes. Relative RISK for males and females was calculated using Poisson regression. STSTA (version 11) software was used for data analysis.
Results: findings revealed that avoidable mortality rate unsteadily from 178.7 in 2004 to 147.3 in 2011 per 100000 population decreased. Annually decline in avoidable death rates was 3.2% [95% CL 5.7-0.7%] p<0.001. Avoidable deaths to total deaths ratio from 38.4% in 2004 to 32.75% in 2011 with some fluctuations fell. The rate of avoidable deaths for men declined as 4.4% per year p<0.001, from 230 in 2004 to 171.5 in 2011 per 100000 population. Conversely, reduction rate for women was not significant p<0.3. Calculation of relative risk using Poisson regression demonstrated that probability of exposure to avoidable deaths for males was 73% more than for their female counterparts [95% CL 1.68-1.82%] p<0.001.however, unavoidable mortality rate increased annually as 0.76% p<0.02.
Conclusion: Our findings suggest that unlike unavoidable deaths, avoidable deaths rate over the time has decreased. Although this decline may be affected by various factors but dominant role of health system is not deniable especially with regard to unavoidable mortality rate has increased. However, the decline rates were different between males and females and that this decline was mostly affected by preventable deaths and ischemic heart disease (IHD) categories rather than treatable one.

Mohammad Azizi, Fatemeh Didehvar, Seyed Mojtaba Sajadi and Aasef Karimi
Currently, entrepreneurship is an important solution to economic and social problems in knowledge-based countries and educational system is a key factor in developing and fostering entrepreneurship. This research investigates entrepreneurial main characteristics and effects of educational plans over students' entrepreneurial intention. The population includes all senior undergraduate and master graduate students of Shahid Beheshti University. A total of 330 students were selected by multiple stage cluster-stratified random sampling method. The analysis were performed using Spearman Correlation Test for determining the relation among entrepreneurship variables, and ANOVA for comparing the entrepreneurship among students of various faculties. Research findings showed significant relation among the amount of ambiguity tolerance, the belief to internal locus of control, the need for achievement, risk taking, creativity and desire for independence with entrepreneurship. The relation between educational programs and curriculums offered by the university was not significant with the students’ entrepreneurship. In other word, current university educational programs were not effective to students’ entrepreneurship intention. There is a great need for new approaches to entrepreneurship. The business environment is different, more challenging, fast changing and competitive. Therefore, the entrepreneurship skills and characteristics should be developed from early stages of life, especially in school. Results indicate that schools and universities should aimed at developing and training entrepreneurship skills in students.
Keywords: Entrepreneurship, student, entrepreneurial traits, entrepreneurial intention, university curriculum.
