The use of document summarization allows a user to get a sense of the content of full document, or to know its information content without reading all sentences within the document. Data reduction helps user to find the required information quickly without having to waste time in reading the whole document. This paper presents a method to generate a summary from the original document. And the method includes several characteristics such as sentence-id, position of each term in a sentence, term frequency, sentence similarity measure and weight of each and every sentence. To solve the optimization problem differential evolution (DE) algorithm is used, which can choose the optimal summary. DE algorithm is based on a fitness function and selection of fitness function is crucial for the good performance of DE algorithm.

The aim of the paper was to analyse the relation between financial leverage on firm’s profitability from the perspective of Nigerian deposit money banks. We employed a random effects regression model with return on asset as dependent variable and three factors (leverage, liquidity and size) as explainable variables. The panel data series was collated from the annual reports and statement of accounts of 14 selected deposit money banks in Nigeria for the period covering 2000-2014. Data was analyzed using descriptive statistics, correlation analysis and panel regression analysis. A panel random effect and panel fixed effect estimations will be processed while the Hausman test will be employed in selecting the most appropriate model. Panel unit root test will also be conducted since our series has a feature of time-series. We have found that financial leverage has a negative impact on profitability. The results of the estimation model show that size and liquidity have positive impact on profitability. As expected, the relationship between liquidity and leverage appears to be negative. Our regression results revealed that firm size is negatively related to leverage. As the selection of independent variables was influenced by availability of data, we consider that our analysis could be expanded by incorporating other determinants factors such as industry-level and country-level variables, so long as the data series are available.

Two field experiments were carried out at Arab El-Awammer Research Station, Agric. Res. Center Assiut Governorate during winter seasons of 2013/2014 and 2014/2015. The present study assessed the effect of crop sequence and nitrogen fertilization on productivity of wheat. The experimental treatments were four crop sequences with three nitrogen fertilizer rates. Treatments were arranged in a factorial experiment 3×4 based on a RCBD with four replications. These results suggest that the sequence of cowpea / clover / wheat and the sequence of cowpea + maize / clover / wheat produced the maximum yield and its components of wheat as compared with the other sequences. Naturally Occurring Biological Control Agents (NOBCA) the maximum number of agents was existed in the sequences of cowpea / clover / wheat and cowpea + maize / clover / wheat. The lowest number was existed in the sequence of maize / wheat. The present research proved that the two promising sequences contributed so much in increasing the cropping area. Therefore, the cropping index was increased to be 2.87 or 3.39 in the year for the two sequences of cowpea / clover / wheat and cowpea + maize / clover / wheat, respectively. These values are considered to be more than the traditional index in Egypt which is 1.73. The net return from the sequence of cowpea + maize / clover / wheat was the highest when compared with the other sequences. Thus increasing the cropping area which increased the cropping index caused an increase in the net return.

The objective of this paper is to analyze the effect of variable suction and radiative heat transfer on unsteady magnetohydrodynamic free convective couette flow of a viscous incompressible electrically conducting fluid in the slip flow regime in presence of variable suction and radiative heat source. The governing equations of the flow field are solved employing perturbation technique and the expressions for the velocity, temperature, skin friction and the rate of heat transfer i.e. the heat flux in terms of Nusselts number Nu are obtained. The effects of the pertinent parameters such as magnetic parameter M, permeability parameter Kp, Grashof number for heat transfer Gr, radiation parameter F, suction parameters ?????; slip flow parameters h1, h2; Prandtl number Pr etc. on the flow field have been studied and the results are presented graphically and discussed quantitatively. The problem has some relevance in geophysical, astrophysical and cosmical studies.

This theory enables to explain that the emotional structure of direct healthcare workers is related to their assurance to the organization. This is an exploratory study, in which larger sample sizes transversely multiple healthcare settings ought to be observed before ultimate inferences must be drawn. Future studies must likely commence other variables such as satisfaction, effort, and even performance appraisals to define causal relationships. A significant relationship is established between emotional intelligence, emotional coping capability, and organizational commitment. In addition, emotional intellect provided as a moderating variable linking coping capability and assurance such that those direct care workers who revealed higher emotional coping capabilities were more dedicated when emotional intelligence was high moderately than low. It emerges that personality constructs such as emotional intelligence and coping ability could possibly be used as extrapolative instruments to conclude who might be most victorious in operating in the highly emotionally charged environment of healthcare. This is an important study that inspected the constructs of emotional intellect and coping ability and organizational commitment by means of a direct healthcare worker sample. It provides support for the assumption that interpersonal emotional dynamics are significant in emotionally charged environments. This knowledge could support healthcare managers in addressing the shortage and abrasion rates associated with many direct healthcare fields.

This study is focused on the empirical analysis of risk on Banks performance in Nigeria using time series data for the period of 1990 to 2014. This study employed Dickey Fuller unit root test, Johansen cointegration test and Parsimonious method augmented with error correction model. The emphasis was to test the long run relationship between non-performing loan, Average Liquidity Risk and the Return on Assets. The result of the analysis are in various folds: First, it shows that the variables were trend stationary and exhibited a long run relationships with Return on Assets (bank performance). The specific findings of the study using error correction model is that non-performing loan has made significant negative impact on Return on Assets while Average Liquidity Ratio has not made significant impact on Return on Assets. Second, this finding confirm that non performing loans is the most critical of all risk components. This study has some important policy implication: The banking operators and regulatory bodies should as a matter of urgency tighten up the monetary apparatus to safeguard and stabilize the depositors money and the banking sector in Nigeria. Also, there should be adequate credit administration, measurement, monitoring processes and good control over credit, liquidity and other risk components.

Energy consumption control in wireless ad-hoc networks is a more difficult problem due to non availability of access point in network. A node can be both a data source and a router that forwards data for other nodes. There is no centralized entity such as an access point to control and maintain the power control mode of each node in the network. There are number of challenges offered by mobile ad- hoc network environment like limited power, route failure, synchronization, security etc. Nodes in the mobile ad-hoc network environment have limited battery power. Extra amount of energy is needed by router to forward and to relay packets. In this paper, literature survey is carried out on energy consumption issues for wireless ad-hoc network.

Supernumerary teeth are one that is additional to the normal series and can be found in any region of dental arch. They duplicate the typical anatomy of posterior and anterior teeth, whereas rudimentary supernumerary teeth are dysmorphic and can presume conical forms, tuberculate form, molariform or odontome. They may be single or multiple, unilateral or bilateral, erupted or unerupted, and one or both jaw. The aim of this report is to present a case of a 13 year old boy with a mesiodens associated with maxillary anterior proclination.

In the current paper, firstly literature is reviewed and various Evaluation of personal disposition level of technology adoption models in different industries are studied and finally, an assessment model selected that it was divided into 7 main classes with 46 indexes.

Then, scores were given to 46 indexes by experts and final score of 46 indexes and 7 main components were evaluated. Considering obtained scores it was specified that the experts of this company has highest capability in habits capability (84.83%) and social influence capability (79%), compared to other components. Also, it has lowest capability in risk taking capability (55.73%) and Psychological resilience capability (64.58%). In addition, innovativeness (78.72%), optimism (76.39%), self efficacy (72.78%), are in average level compared to other components. Finally, some recommendations are made regarding components and indexes with lower score in the organization.

The efficiency of capital market is one of the most controversial issues in the capital market over the past three decades in financial literature. Today, the capital market in developing countries is considered as a means to increase investment and economic growth and since efficiency is the main and most important characteristic of capital market in each country, it has become one of the most controversial areas of finance and economy research. In this study, performance of Tehran Stock Exchange is examined in the period (Persian date April 2001 to March 2010) on a daily basis, using VAR method. This study is distinct from similar domestic research because the present research examines the efficiency of Tehran Stock Exchange simultaneously with the efficiency of four indices (total, price and dividends, finance and industry) that the results showed that Tehran Stock Exchange does not have efficiency based on four elected indices.
