Abstract: Physico-chemical parameters of Temperature, Dissolved oxygen, pH, Transparency, Conductivity, and free carbon dioxide of lower Usuma Reservoir was carried out from April to October 2010 in two selected sampling stations to ascertain the effect of human activities on water quality for fish production. The stations were selected based on the degree of human activities, station 1 have a high degree of human activities and station 2 with little or no human activities. The water temperature ranged between 26.13^oC – 31.00^oC, dissolved oxygen ranged between 3.29mg/l – 10.50mg/l. The pH, transparency, conductivity and free carbon dioxide were 6.00 –7.50, 1.20m – 2.43m, 0.21µs/cm – 0.98µs/cm and 2.00mg/l – 9.00mg/l respectively. There was significant difference (P <0.05) between all the parameters measured and the stations but all the recorded values were within the limit for fish production.

ABSTRACT: This study on the constraints to effective management of secondary school libraries was carried out using the survey method. Questionnaire was used to collect required data and simple tables and percentages were used to analyze the data collected. During the course of the study, it was identified that inadequate funding by the government is the major constraints to effective management of school libraries. Data gathered also showed that the area mostly affected by this constraint is in provision of library/information resources. The libraries under study have been coping with these constraints through alternative funding. However, the researcher made some recommendations among which are inadequate funding by government.

Abstract: This work was designed to the study some heat resistance characteristics of the isolates obtained in relation to fruit processing parameters. The effect of heat (85⁰, 90 ⁰, 92.5 ⁰ and 95 ⁰C) in combination with common fruit products preservatives (sodium benzoate and citric acid) and sugars (fructose and sucrose) on inactivation of  ascospores of N. fischeri and T. flavus were studied in water, phosphate buffers, grapefruit, orange and pineapple juices. The rate of thermal inactivation was highest in medium containing sodium benzoate. The presence of sugars (sucrose and fructose) in juices protected the ascospores against heat inactivation when compared with plain juices. Ascospores of T. flavus had D₈₅ ⁰_C values which ranged from 10.6 to 78.9min; D₉₀ ⁰_C values of <1 to 13.6min and D_92.5 ⁰_C values of <1 to 8.1min. Ascospores of N. fischeri had D₈₅ ⁰_C values which ranged from 61.9 to 217.5min; D₉₀ ⁰_C values of 5.0 to 62.6min; D_92.5 ⁰_C values of 1.1 to 19.7min and D₉₅ ⁰_C values of <1 to 13.6min. These results mark the high heat resistance of ascospores of heat resistant fungi isolated from the tropics. Heat resistant fungi not only cause spoilage of fruit products but also produce highly toxic and sometimes carcinogenic compounds; these findings are of utmost importance to fruit processing industries which are presently increasing in number in Nigeria and other developing countries.

Abstract: The main objective of this research is to present a model to assess the situation of human resource management in Iranian organizations. To do this, the Organizational Excellence Model of performance appraisal has been selected among the other models. Thus, based on the criteria of the model, we will present a model to assess the performance of the human resource. Moreover, equipped with the mentioned model, the research will evaluate the existing gap in the human resource management of the studied organization and will offer some suggestions to improve the situations. In current era, the organizations will survive who can be responsible for the needs and wants of their customers and beneficiaries. Using such models the organizations can evaluate the rate of their success in administering the improvement programs at different periods of times at one hand, and compare their performance with other (and best) organizations at the other hand. This research is an applied research in its objective, and it is a descriptive- analytic one in its data gathering. Since the subject of the research has been available for the researchers and the study has being done at the place of the research, so it is a field study. According to the findings of the research, the deepest gap is observable in the results of the customers and "human resource management customer results" and the "people results".

Abstract: Communicative Language Teaching (CLT) is very much significant for learning and teaching practices where the students and teachers are involved to communicate in a second language. It represents a change of focus in language teaching from linguistic structure to learners’ need for developing communication skills. Though a number of researches have been implemented on taking CLT in Bangladesh, no fruitful result is seen especially in college level education in Bangladesh where the teachers are the authentic factor and their attitudes play a crucial role in revealing their thinking about CLT and their implementation of CLT in the classrooms. So, the study aimed at investigating Bangladeshi college teachers’ attitudes toward CLT and the reasons behind attitudes the teachers held toward CLT. For this, a number of data were collected through questionnaire survey where the populations were college teachers. The respondents were from the different colleges in four districts (Khulna, Satkhira, Bagerhat and Jessor) in Bangladesh. The results of this study indicated that the teachers held favorable attitudes toward principles of CLT and displayed characteristics of CLT in their beliefs. Also, the results demonstrated that Bangladeshi college teachers (English) believe CLT can make English teaching effective and meaningful.

Abstract: On the 19^Th January 2012, the opening session of the interval meetings of the Neuro-Oncology Scientific Club (NOSC-THN) was held in Tehran, Iran. The NOSC is a newly established scientific forum which currently has formed provincial steering boards in the country and is expected to be turned to the national NOSC in its future perspective. The interdisciplinary nature of this club provides a multifaceted approach for diagnosis, treatment and follow-up of brain tumor patients. Participants utilized this transparent and unbiased round table to contribute to discussions and decisions. All comments were open to debate, with interdisciplinary team work for brain tumor patients’ health and quality of life at the center. This paper summarizes the communicated insights (neurosurgery, radiodiagnostics and radiochemotherapy) and the suggested strategies during the first NOSC-Tehran meeting hoping to let readers further perceive the significance of the interdisciplinary approach as a practical model in CNS tumor patients’ care.

ABSTRACT: Acetaminophen (APAP) overdose has been reported to cause severe liver damage. This study was therefore designed to access the modulatory effect of Tapinanthus globiferus on possible side effects due to acetaminophen overdose. APAP induced hepatotoxicity which was indicated by elevated gamma glutamyl transferase (GGT) and aspartate aminotransferase activities (AST); reduced serum total proteins and albumin; elevated tumour necrotic factor-alpha (TNF-α) and interleukin-2 (IL-2); and increased lipid peroxidation as evidenced by elevated malondialdehyde in hepatic tissues. However, administration of T. globiferus caused reduction in activities of GGT and AST; hepatocyte malondialdehyde, TNF-α and IL-2 concentrations and increased total proteins and albumin when compared with groups given only APAP. Determination of biocomposition showed APAP contain high concentration of phenolic contents. The observation implied that T. globiferus possess antioxidative and anti-inflammatory activities and its administration may reduce damages due to acetaminophen administrations in hepatocytes.

Abstract:Scabies is an infestation of the skin by microscopic itch mite, Sarcoptes scabiei var hominis favoured by poor conditions of hygiene, poverty and overcrowding. Objectively this study will provide a baseline data that will signal the public health significance of the disease in Maiduguri.  This is a four year review on the prevalence of human scabies in Borno State, Nigeria conducted between 2004 and 2007 using patient’s data assessment (PDA) from University of Maiduguri Teaching Hospital (UMTH), State Specialist Hospital (SSH) and Molai Leprosarium. Out of the 1020 patients examined 983 (96.4%) were infested with 49.9% as male and 50.1% female (p>0.05); 77.2% as children and 22.8% as adults (p<0.05). The highest rate was observed in unemployed patients (65.5%) and the lowest in commercial vehicle drivers (0.3%) (p<0.05). The findings in this study have indicated that factors such as the occupational status, age and sex of patients could influence the spread of scabies amongst people of Borno State, Nigeria.
