This study was carried out to investigate the effects of using treated wastewater on quantitative and qualitative characteristics of Lolium perenne in greenhouse conditions in Sa'dabad of the Dashtestan, Iran. Experiment was performed in a randomized complete block design with 5 treatments and 4 replicates. Treatments included: fresh water, fresh water + 25% treated wastewater, fresh water + 50% treated wastewater, fresh water + 75% treated wastewater, and 100% treated wastewater. Based on the results, it can be concluded that the impact of wastewater had significant effect on growth and physiological characteristics. Root weight (6.7 g), leaf weight (3.6 g), leaf area (8.4 cm2), root length (33 cm) and plant height (11.3 cm) showed a significant increase in compared to the control. In relation to the characteristics of protein, phosphorus and ash, the same trend was observed.

Evaluation of “mgbam” traditional food on haematological profile and some selected biochemical parameters was carried out using standard methods. Fifty-six male wistar albino rats were separated into seven groups of eight rats each. One group served as the control, two groups served as reference groups while the other groups served as test groups. The reference foods were basal feed and nutrend (commercial infants’ food). The test groups were placed on compounded feed formulated with prepared “mgbam” and pelletized commercial rat feed using different proportions. Results obtained for haematological profile and biochemical parameters revealed that the studied food is good for health. This study has revealed the evaluation of “mgbam” traditional food on haematological profile and some selected biochemical parameters.

This paper explores the dimensions that contribute to leadership excellence in Thailand and empirically tests the Selvarajah, Duignan, Nuttman, Lane and Suppiah (1995) model. Summated scales for the importance of Excellent Leadership, Personal Qualities, Managerial Behaviours (MB), Organisational Demands, and Environmental Influences were developed. A structural model was constructed to explain the relationship in excellence in leadership. 403 managers participated in this research. The findings suggest that there are strong cultural factors such as non-confrontation and respect moderating the perceptions of Thai managers with regard to an Excellent Leader. Thailand attracts international investor interest and the relevance of behavioural values for business is of great importance to human resources management. There is limited literature on Thai management and leadership styles and the available literature has not linked cultural values and norms to leadership constructs in Thailand. The findings in this paper are important for managers on foreign assignment in Thailand and for others who engage with Thailand.

This experiment was conducted to determine the potential of formulated Annona squamosa (Linn) and Moringa oleifera (Lam) against Podagrica species (jacoby) and Zonocerus variegatus (Loew) of okra during the major planting season of 2013 and 2014. The experiment was set up in a Randomized Complete Block Design and each treatment was replicated three times. The paste was separately mixed with Texapol, Nitrosol, Black soap and Salt at different proportion. The solution collected was stored in a 5-littre keg for further use. The result revealed that the formulated extracts had significant effect in all the tested parameters when compared with unprotected plants. Ethanolic plant extracts had higher insecticidal efficacy (36.1 to 46.9%) than Acetonic extracts which had the efficacy ranging from 18.4 to 29.3%. The yield obtained from ethanolic plant extracts treated plots was two times that of Acetonic extracts. The solution was stored at a room temperature for three months without being fermented. Therefore, these plant extracts can be used in the management of insect pests of okra especially in organic farming system.

Studies show that the number of debris in Low Earth Orbit is exponentially growing despite future debris release mitigation measures considered. Especially, an already existing population of small and medium debris is a concrete threat to operational satellites. Ground based DF-laser and space based Nd YAG-laser solutions which can remove at low expense and in a non-destructive way hazardous debris around selected space assets appear as a highly promising answer.

The study examined the extent to which impulsivity and sensation seeking predispose adolescents to sexual risk taking in Kisumu, Kenya. The study was carried out in Kisumu Municipality being one of the leading regions in Kenya in HIV prevalence (15%), a likely indication of high sexual risk taking. A sample size of 384 was drawn from a population of 10,278 secondary school students, but only 357 completed the study questionnaires. Quantitative data was analyzed using descriptive statistics while the qualitative data was summarized thematically. The male respondents comprised of 156 (43.7%) while the female respondents were 201 (56.3%). The results indicated that about half the adolescents in the study were highly impulsive and sensational seekers predisposing them to take up risks. Sensation seeking was a better predictor of sexual risk taking than impulsivity especially among the male adolescents, while impulsivity was a better predictor among female respondents. The study recommended that behavioral and communication strategies being developed for adolescents should be gender differentiated since male and female adolescents respond differently to the different aspects of sexual risk taking behaviors.

More than 80% of roadway mileage in the world carries less than 400 vehicles per day and these roads are classified as low volume roads. India has essentially a rural oriented economy with 72% of its population living in villages. The low volume roads are part of tertiary road system, which consists of other district roads and village roads. The traffic conditions on these roads are distinctly different from the major roads. A variety of vehicles are used for transportation of goods on rural roads, ranging from bullock-carts to the fast moving commercial vehicles. Permanent deformation of the unbound base and sub-base layer is one of the distress types on these roads that require extensive maintenance. The gradation is the most important property that an aggregate can contribute to the performance of pavement. In the present study, an attempt has been made to investigate the rutting potential of low volume roads, taking into account base course gradation, sub-base course gradation, sub-base field density, subgrade field density, subgrade moisture content, subgrade California Bearing Ratio, and traffic volume. The influence of these factors on the rutting potential of in-service pavements has been investigated and a response type model has been developed.

Shot-peening is a cold-working process primarily used to improve the fatigue life and strength of metallic structural components. In this work, the shot-peening time (SPT) effect on fatigue life of 7075-T651 Al-alloy was investigating at room temperature stress ratio R=-1 and reversed bending. An increase in shot-peening time (SPT) resulted in an increase in fatigue life improvement percentage (FLI %). For 5 SPT, reducing the applied stress, increasing (FLI%) while at 10 and 15 SPT reducing the applied stress reducing the (FLI%).

In this work, an experimental study was carried to obtain the fatigue damage for aluminum alloy, 2024-T4 under rotating bending loading and stress ratio R= -1. The experiments were done at RT(room temperature) ,25oC ,and 200oC. A modified damage stress model was suggested to predict the fatigue life under elevated temperature which has been formulated to take into account the damage at different load levels. The microstructure and hardness of aluminium alloy after fatigue-creep interaction testing have been investigated. Attention has been paid to the role of the microstructure and hardness on the fatigue-creep strength of aluminum alloy. It has been shown that, there is a little effect of microstructure in the cyclic response of aluminum alloy, while the hardness has a significant effect on the fatigue-creep strength. This is described numerically.

The study centred on lecturers’ involvement in decision making and job enhancement in Colleges of Education in Cross River State, Nigeria. Two research questions and hypotheses were developed to guide the study with ex-post facto research design and the population of the study comprised all lecturers in Colleges of education in Cross River State, Nigeria. Data obtained from the registrar units of these colleges showed that there were one thousand six hundred and forty five (1,645) male and female lecturers in these Zones. Applying Tara-Yamene’s formula for a sample size of 503 from a finite population of lecturers’. The study adopted stratified random sampling technique to determine the sample for the study and the instrument for data collection was a questionnaire tagged Lecturers’ Involvement in Decision Making and Job Enhancement in Colleges of Education in Cross River State, Nigeria (LIDMJEQ) was constructed by the researcher to elicit data from the respondents. The drafts of the instruments were given to three experts - one from the Department of Educational Foundations and Administration, and two from Measurement and Evaluation, all from the Cross River University of Technology, Calabar. A trial test was carried out using forty (40) lecturers’ who were comparable groups outside the study area. The data obtained were analyzed using the Cronbach Alpha reliability method to determine the internal consistency reliability of the instruments. The data was analysed using one way ANOVA. The findings revealed that there is no significant influence of lecturers’ involvement in major decision-making and their job enhancement. Also, Lecturers’ involvement in minor decision-making does significantly influence their job enhancement. It was recommended among others that School leadership should involving their lecturers’ in the school major decision-making processes.
