Trials were carried out using five composite maize varieties in a Striga lutea (Lour) endemic soil of Temidire-Eruwa, Oyo State, Nigeria, in 2004 and 2005. The composite maize varieties were tested under varied fertilizer types, Nitrogen (N) concentrations and artificial striga infestation. The objective was to test these striga resistant maize varieties for yield and agronomic performance under the above conditions. The result showed that, variety and year of evaluation differed significantly (P<0.01) for almost all agronomic characters such as plant stand, days to anthesis (silking and tasselling), plant and ear heights as well as root and stalk lodging resistance at both 100kgN and 200kgN/ha. Variety x Year interaction were also significantly different (P<0.01) for all agronomic characters except root lodging and husk tip cover. Fertilizer type differed only for days to silking, plant height and plant aspect, while Year x Nitrogen source and Variety x Nitrogen source was highly significant (P<0.01) for field weight. Plant stands were better in 2004 than 2005 for all varieties except Acr 97syn-W and DMR-LSR-W. The composite maize varieties tolerated high N-concentration except DMR-LSR-Y which do not utilize excess Nitrogen above 100kgN/ha. Use of striga resistant maize varieties concomitantly with Nitrogen fertilizer is recommended for farmers in Striga lutea endemic ecology, for higher grain yield.

Demotivation, as important concept in psychology, is in fact the dark side of motivation. Research into foreign language learners? demotivation for their weaknesses in translation practice has not been touched by the translation scholars. To this end, the researchers distributed an open-ended questionnaire to 112 students majoring in translation studies at Ghuchan Azad University and Mashhad Imam Reza University. Having categorized the responses, they found that the most commonly cited factors included lack of job (0.24), teaching method (0.20), a boring task (0.12), teacher feedback (0.10), insufficient knowledge of vocabulary (0.8), and lack of group work (0.5). No effect on general English, confusion in translation courses, and lack of concentration were the least commonly mentioned factors. The factors show that students need extrinsic motivation or instrumental motivation to pursue their studies or at least to exert enough effort and perseverance in their courses.

Trials were carried out using five maize varieties in Ibadan, Oyo state Nigeria in 2010 and 2011 maize cropping seasons. The varieties were planted in a randomized complete block design of three replicates. The objective was to evaluate the relationship existing among various growth and yield components as they contribute to grain yield. The result showed that varieties differed significantly in days to 50% flowering, field weight and number of kernel per cob (P<0.05), leaf area, ear length and 1000 grain weight (P<0.01), plant height and grain yield/ha (P<0.001). ART98-SW5OB and Obatanpa were superior in almost all the agronomic traits evaluated while ART98-SW6 OB was least in plant height and produce flowers earlier than the other varieties. Years, variety and years of evaluation interaction were however not significantly different. Ear length correlated positively and strongly with plant height and number of kernels per cob (P<0.001). Plant height and other agronomical traits were positively associated with grain yield except days to 50% flowering and numbers of kernel per cob. Growth and yield components are related in one way or the other; hence selection for secondary yield traits that correlate positively with primary yield components is fundamental to the overall grain yield development in maize.

The contamination of water by toxic heavy metals is a worldwide problem. The presence of hexavalent chromium in waste water is a potential hazard to aquatic life and humans. Biosorption of heavy metals is an important technique used in the removal of toxic metals from various sources like industrial waste, aqueous systems and municipal waste waters. Metal removal technique using non-conventional adsorbents such as microorganisms are cheap because of the low cost of adsorbents used and many represent a practical replacement to conventional processes. There are various mechanisms such as kinetic models and adsorption isotherms employed for the efficient removal of hexavalent chromium from various sources. The present review discusses brief findings of hexavalent chromium removal with the maximum metal uptake by using living and non-living microorganisms as adsorbents.

This study, entitled "Investigating the Effect of Emotional Intelligence on the success of business in marketing" was conducted with an overall objective and 5 sub-objectives in the Bou Ali industrial estate of Hamedan in 2013. This research is a descriptive-analytic study in the form of a causal - comparative survey. The research population is 180 individuals and includes all the managers and persons in charge in the manufacturing and service factories in Bu Ali industrial estate. The sample size was estimated at 123 by Cochran's formula and it was randomly selected. Data were analyzed through three questionnaires. One standardized Sybrya shrink EQ questionnaire with 33 questions and emotional intelligence two self-report questionnaires for marketing intelligence and marketing success, collecting using SPSS software version 19 and by multivariate regression. Face and content validity of three questionnaires were estimated and then assessed by Cronbach's alpha coefficient, which in all questionnaires was 70/0. Results showed that emotional intelligence had effect on the success of marketers and marketing firms. Accurate results suggest that the two self-awareness and self-control factors significantly correlate with the success of marketers and persons in charge of marketing firms. The other three factors of self-motivation, social awareness and social skills have no significant correlation with the variable of success of marketers and persons in charge of marketing firms. Also, between the two factors of self-awareness and self-control, self-control factor is more effective than the other.

Human resource excellence is a comprehensive framework of pivotal values, criteria and superior indices in all aspects of organizational human resources, and helps manager identify their strength and weakness by continuous assessing of activities, trends, processes and human resource outcomes in order to plan for improvement. In this case, HR excellence models are appropriate for assessing the performance of an organization, by which organizations can compare their performance with competitors on national and international scale. Present research is intended to assess HR excellence in Niroo Mohareke Company based on PD model. The statistical population and sample is senior HR managers and consultants of this company. To collect data HR excellence questionnaires was used, and alpha Cronbach coefficient was used for final estimation (?= 0.92). After the questionnaires were handed and collected, the obtained information was analyzed using descriptive and inferential methods. All five HR excellence criteria were evaluated using independent T Student test, correlated T Student test and Friedman test. The findings suggest that all PD criteria are not in a favorable situation, which the least interest is in strategic and personnel planning criterion and the biggest gap between existing and favorable situations correspond to personnel and leadership, respectively.

In this paper, we study some of the properties of interval valued fuzzy subhemiring of a hemiring and prove some results on these.

Abu Hanifa Dinavari is one of the most prominent scholars of Islamic civilization and the glories of Iranian history and culture with a venerable and high position in various branches of science especially botany, astronomy, mathematics, mechanics, atmosphere science, climate change (Elm al-Anvae), lexicology, literature, grammar and syntax, interpretation of Quran sciences, historiography, and other branches of intellectual sciences and traditional knowledge. His brilliant knowledge and ample publications made him one great scholar among several scientists and knowledgeable scholars of his time, so that he influenced many sciences. However, his scientific status is not as high as what he deserves to be. What has influenced his character more than anything in scientific circles and among scholars is his historiographical approach due to the publication of the complete text of Al-Akhbar at-Tiwal. While criticizing this viewpoint, the present paper attempts to study the scientific-cultural status and function of Abu Hanifa Dinavari in Islamic civilization. Also using a new and comprehensive approach, and by a complete and more deeply approach and in proportion to the effective position of such scholar in Islamic civilization, the study aims to analyze intellectual thinking and different scholarly and scientific aspects of this distinguished scholar. In addition, with a careful and thorough review and introducing Abu Hanifa Dinavari works, different aspects of his knowledge and character will be further clarified in the study.

With the rapidly growing use of www in business sectors involving e-Business, e-CRM, Digital Libraries and so on, there arises a strong need for performing web log analysis to ensure the security of organization and also to drive the growth of any organization. However there exist many systems for performing the web log analysis, the results they generate are far from the expectations. The major challenges for designers of such systems is to develop an efficient analysis algorithm that generate the precise outcome to identify the exact usage pattern of different web users and at the same time find the most common usage pattern.

The FT-IR and FT-Raman spectra of 2-bromo-m-xylene (2BMX) have been recorded in the regions 4000–400 cm?1 and 4000–100 cm?1, respectively. The fundamental vibrational frequencies and intensities of the vibrational bands were evaluated using density functional theory (DFT) using standard B3LYP method and 6-311+G** basis set combinations. The vibrational spectra were interpreted, with the aid of normal coordinate analysis based on a scaled quantum mechanical force field. The Infrared and Raman spectra were also predicted from the calculated intensities. The Mulliken population analysis of the molecule is computed by using DFT calculations. The calculated HOMO and LUMO energies shows that charge transfer occur within the molecule. Further, density functional theory (DFT) combined with quantum chemical calculations to determine the first-order hyperpolarizability. Electronic excitation energies, oscillator strength and nature of the respective excited states were calculated by the closed-shell singlet calculation method were also calculated for the molecule.
