Abstract: This research has been conducted to study differences among personality types and occupational stress and organizational commitment among public and private banks in Iran. Statistical society in this study are all employees of City Bank (private) and Mellat Bank (public) who were selected by random cluster sampling method from Tehran and then 180 employees from City Bank and 120 employees from Mellat Bank were selected among them. In this study, questionnaires of occupational stress Philip. L. Rice, personality types Myers - Briggs and organizational commitment Alan Meyer has been used. Also correlation method and comparing means test have been used in this research. Resulted findings showed that there is no significant difference between personality types of employees in Shahr and Mellat Bank, on the other hand mean of continuous and emotional commitment in Mellat Bank is higher than City Bank and mean of normative commitment is almost similar. Mean of occupational stress in field of interpersonal relations and physical condition in City Bank is higher than Mellat Bank and mean of occupational stress in field of occupational interests is similar in two banks.

Abstract: Present study investigate pathogencity of falvobacteria on Red Sea cultured Humor Epinephelus polyphekadion with a trial for treatment and control it using hamate substance and oxytetracycline. Naturally infected Humor fish Epinephelus polyphekadion was stocked in cement ponds along Red sea private fish farm. Large number of fish suffering from discoloration, ulcers on the skin, erosion in fins and mouth. 90 naturally infected fish was divided into three groups with three replicates 1st group infested non treated,2nd group treated with humate substances 15 mg/kg body weight in diet for 45 days, 3rd group treated with long acting oxytetracycline 75 mg/kg body weight in diet for 10 days. blood samples were taken at the end of every week for three weeks post treatment, mortality rate, RBCs count, total WBCs count, cortisol concentration in serum and phagocytic index were recorded along 3 weeks post treatment. the study concluded that Flavobacteria infection in Shahwan fish should be diagnosed and treated as quick as possible to avoid fish mortalities and economical losses, using natural treatment such as humate substances which is recommended and preferable than antibiotics (oxytetracycline) treatment in fish bacterial infection as their application as it is cheap, more safe, and of little side effects on fish.

Abstract: This paper discusses the attitudes students have towards Communicative Language Teaching after their primary education. Although research of a similar nature has been done, the present research complements others by following 97 students in the school level studies, and it provides another avenue for examining the language situation in Bangladesh. The findings suggested that students were generally comfortable with the language environments and courses offered in secondary settings; they agreed that learning English through CLT method is important in the computer era. The respondents in the present study, who had just obtained their first degree (Primary Education), reported that group work activities are essential for communication and in promoting genuine interaction among students and by mastering the rules of grammar, students become fully capable of communicating with a non-native speaker. The respondents also reported that most of the students acquire their English knowledge for communication with others effectively when CLT is used in their classes through text book which helped them obtain the language needed for career and personal growth. They realized how important it is to possess a positive attitude towards the use of CLT for learning English.

ABSTRACT: This study determined the prevalence and antibiotic susceptibility of bacterial agents involved in lower respiratory tract infections in patients in Abeokuta metropolis between June-December, 2011. Out of the 165 sputum samples, 40(24.24%) were positive for bacterial cultures. The result shows that LRTI were more prevalent in males than in females. Among the isolates, Klebsiella pneumoniae 28(70.0%) was the most isolated organism, Streptococcus pneumoniae 7(17.5%) was next, followed by Escherichia coli 3(7.5%) and Pseudomonas aeruginosa 2(5.0%). Age group 31-40 years had the highest prevalence 9(22.5%) of LRTI while, age group 11-20 and 61-70 years had the least 2(5.0%). The result of the sensitivity test indicates that Gram-positive and Gram negative isolates showed highest sensitivity to Ceftazidime, Levoxin, Augmentin and Ceftraxone, while high resistance was recorded for antibiotics such as Ampiciilin, Amoxicillin, Cloxaciliin, and Cotrimoxazole. This observation poses a serious public health problem.

Abstract: In this study, surface modification of Fe3O4 nanoparticles was carried out with sodium dodecyl sulfate (SDS). The obtained modified nanoparticles (SDS-Fe3O4 nanoparticles) were evaluated for Cd(II) removal from aqueous solution by batch adsorption method. Characterization of the SDS-Fe3O4 nanoparticles were performed by Scanning Electron Microscopy (SEM), Furier transform infrared (FTIR) and X-ray diffraction (XRD) analysis. The batch experiments showed that SDS-Fe3O4 nanoparticles can be effectively used to remove Cd(II) from aqueous solution. Maximum removal of Cd(II) was obtained at pH=6 and adsorption equilibrium was achieved in 30 min. The adsorption kinetics well fitted using pseudo second-order kinetic model. The adsorption isotherm data could be well described by the Freundlich equation. The maximum adsorption capacity of SDS-Fe3O4 nanoparticles for Cd2+ was found to be 7.466 mgg-1. The results indicated that SDS-Fe3O4 nanoparticles can be used as an effective adsorbent for removing cadmium from contaminated water sources.

Abstract: This study investigated the age-related disparities in the prevalence of pulmonary Tuberculosis in the Port-Harcourt metropolis of Rivers-State, Nigeria. A total of 1038 sputum samples were collected from in and out patients of the University of Port- Harcourt Teaching Hospital for a period of one year. Three (3) deep cough samples were collected per patient over a period of three days. The samples were examined macroscopically and microscopically. The Ziehl-Neelsen technique for the detection of Mycobacterium tuberculosis in sputum was carried out. The sputum samples were also cultured using MacConkey, Chocolate and Blood agar. Biochemical tests were used for identification. Of the 1038 samples collected, 348(33.5%) tested positive and 690(66.5%) were negative for acid bacilli. From this study, the age ranges of subjects were 1 to 80 years. The study showed that there was a significant difference between age groups for carriage rates of AFB between children and more elderly adults (46.3% vs. 8.8%, P <0.05), between adolescents and more elderly adults (31.1% vs. 8.8%, P <0.05) and between younger adults and more elderly adults (38.3% vs. 8.8%, P <0.05). The study showed that there was no significant difference between age groups for carriage rates of AFB between children with positive and negative AFB smears (46.3% vs. 53.7%, P >0.05) and between younger adults with positive and negative AFB smears (38.3% vs. 61.7%, P >0.05). The study also showed that there was a significant difference between age groups for carriage rates of AFB between adolescents with positive and negative AFB smears (31.1% vs. 68.9%, P <0.05), and between more elderly adults with positive and negative AFB smears (8.8% vs. 91.2%, P <0.05). In conclusion, the 33.5% reported in this study assumed significance and is also an indicative of an emerging epidemic in Port Harcourt, Nigeria. Continued research on age and tuberculosis need to be geared in the direction of ascertaining the magnitude of age disparities in tuberculosis, from contracting the disease to successful recovery and rehabilitation and examining the causes underlying any age disparities, to understand the extent to which these are biological, social/cultural or operational, through comparative studies in disease settings.

ABSTRACT: Squash leaf curl virus (SqLCV) was isolated from squash plants cultivated in Fayoum Governorate. Field inspection of squash leaf curl viral disease was determined according to visual symptoms. Squash plants naturally diseased with SqLCV showed systemic viral symptoms of leaf curling, leaf crinkle, vein banding, fruit malformation and stunting. Virus was confirmed using PCR. Bemisia tabaci insect was able to transmit SqLCV from infected to healthy squash seedlings. The resultant purified virus preparation gave a UV spectrum typical of nucleoprotein. Maximum and minimum absorbance was recorded at 257 and 245 nm, respectively. The purified virus yield obtained in this study was 1.1 mg/ml/100g leaf tissues using the extraction coefficient of 7.7. Light microscopy was used to recognize the effect of squash leaf curl virus (SqLCV) on the anatomy structure of different organelles such as stem, leaf petiole and leaf blade. The results obtained showed that: Infection of squash plants by squash leaf curl virus (SqLCV) led to a decrease in stem section diameter by (10.9%), this decrease was due to the decrease in average diameter of cavity by (33.3%). While, other stem components measurements were showed an increase in its measurements; infection of squash plants by SqLCV decreased the section diameter of leaf petiole by (24.4%), this decrease resulted from the decrease in average thickness of ground tissue by 25% and decrease of average diameter of cavity by 17.9%. While, the other leaf petiole components was less affected; squash leaves were greatly affected as a result of the infection by squash leaf curl virus (SqLCV). This infection was led to an increase in midvein dimension by (22.2% x 28.0%). This increase resulted from the increase in midvein vascular bundle dimension by (127.3 x 76.9%). Electron microscopy was used to recognize the internal changes on internal organelles due to infection of squash leaf curl virus (SqLCV). The results obtained showed that, severe damage in chloroplasts including thylakoids in garana; uneven thickening in the cell walls resulted from developing the curly symptoms in squash leaves; severe damage in mitochondria; aggregates of cytoplasm; nucleus becomes swelled.

Abstract: Problem statement: Extraction of features in object class recognition researches previously gives attention to local features as discriminative features. This is because local features have invariant properties that are robust to viewpoints, translation and rotation. However this feature still has a limitation to represent high-level representation of objects. The problem will occur if the object is too small and do not have strong local features. Approach: This study proposes the combination of different features with local features for improving performance of object class recognition. The objective of this study is to address the problem of building object class representation based on these different features. The different features are sourced from boundary-based shape features. The dataset used consists of segmented objects with unrestricted poses and sizes from publicly image database. Both types of features are combined using feature fusion approach by concatenating those features in a new single feature vector. This new feature vector is trained by Support Vector Machine (SVM) to predict of unknown object class. Result/Conclusion: Experimental result show the inclusion of more than one type of features yields improvements of object class recognition compared to using single feature.
