Abstract: This paper demonstrates the students’ attitude towards English language learning at secondary level education. The present study is implemented by following 57 students in the secondary level education in Bangladesh. The findings suggested that students were not generally comfortable with the language environments and courses offered in secondary settings; they agreed that learning English is important for them. The respondents in the present study, who had just obtained their primary education, reported that the syllabus in secondary level (school) helped them obtaining the language needed for career and personal growth. The findings of the study also showed a positive attitude towards the learning of English at the secondary level education in Bangladesh.

Abstract: A study was conducted to investigate the prevalence of nematodes of domesticated guinea fowls slaughtered at the Maiduguri central market. Postmortem examinations of 100 samples each of trachea and gastro-intestinal tracts revealed an overall prevalence of 90%. Male guinea fowls had a higher prevalence of infection 35.6% compared to the females 64.4% (p >0.05). Parasites identified were Heterakis gallinarum with 20%, Ascaridia galli 6.7%, Subulura brumpti 13.3% Strongyloides avium 11.1% and Capillaria bursata 2.2%. Mixed infections were those by Ascaridia galli and S. avium 15. 6%, H. gallinarum and S. avium 15.6%, H. gallinarum and Subulura brumpti 6.6%, A. galli and H. gallinarum 6.6 % and S. avium and Sub. brumpti and A. galli and Syngamus trachea with 2.2%. These findings indicate that guinea fowls harbor nematodes that are parasitic, and the effect of these parasites on the productivity of the guinea fowls is discussed. Some factors of these parasites are also considered.

Abstract: This research is tackling a triple-link among personality, self-management and conflict. It shows how personality may represent the base that allows individual a sort of self-management against the non-issue based conflict. It suggests that the big deal of people's conflicts and problems inside organizations is steaming from their insisting to deal with people who have the same personality type and/or characteristics as they have. This is hardly occurred in reality, due to the normal creation of people as different from others. Primary data that are firstly collected from the field by questionnaire and then statistical test processing were the two steps which have been successively used to examine such a triple-link. The previously mentioned three variables were hypothetically expressed to show; personality racism as independent variable, self-management as a mediator, and non-issue based conflict as dependent. This was occurred indirectly through testing two interrelated hypotheses and then directly through another hypothesis to certify the link between the independent and dependent variables without using the mediator. There was a statistically indicative significant relationship between the independent and dependent variables with and without the intermediary one. The field study chosen for empirically conducting this research was the Egyptian university hospitals, and the population targeted inside theses hospitals through a stratified random sample was precisely represented in the academic staff doctors working there. Creating people's awareness and acceptance of personality differences were the two invaluable advices to recommend for having an easy to use self-management theory against the big amount of interpersonal non-issue based conflicts.

Abstract: Lasianthera africana, Heinsia crinata and Gongronema latifolium were screened for their phytochemical contents and composition, while vitamin contents, mineral elements and proximate values of the plants were analysed using standard procedures. A comparative analysis of the results showed that alkoloids and cardiac glycosides were not detectable in G. latifolium which rather contains high levels of other phytochemicals such as anthraquinones (23.3+0.03mg/100g), cyanogenetic glycosides (19.0+0.00mg/100g), saponins (18.2+0.02%), tannins (16.1 + 0.03mg/100g) and flavonoids (11.0+0.10mg/100g). However, L. africana and H. crinata had some phytochemical contents and compositions such as saponins (15.9+0.00% and 16.1+0.01% respectively), besides some levels of tannins (10.0+0.00mg/100g and 0.3+0.00mg/100g respectively), pointing to their medicinal potentials. Nutritionally, G. latifolium had significantly high concentrations (P < 0.05) of vitamins A, C, E and niacin, besides minerals such as Se, Cu, Mg and Cr, while thiamine was significantly high (P < 0.05) in H. crinata. Carbohydrates, proteins and fibre were relatively high in the three plants, unlike fat which was equally low. It is concluded that, although the three plants are medicinally and nutritionally potent, G. latifolium appears to be most potent.

Abstract: Cryptosporidium spp. and Giardia duodenalis are 2 protozoan parasites that affect humans and a wide range of domestic and wild animals. These parasites are a major cause of diarrheal disease in humans and animals worldwide, causing high morbidity in their hosts, in immunocompromised hosts and children, they can lead to death. The purpose of this study was to assess the frequency of Cryptosporidium spp. and Giardia spp. in the northern part of Delta (Damietta governorate) and the risk of human infection of these protozoa related to personal data, socio-cultural and environmental characteristics, and the presence or absence of symptoms/signs among a rural and urban population. In order to assess the prevalence of these protozoa among population in the northern part of Delta and the risk of human infection, 330 people (175 females and 155 males) with or without symptoms who attended a Health Care Center were parasitological studied. Of the surveyed population (330), 3.6% were infected with Cryptosporidium spp. only or 24.2% with Giardia spp. and 2.4 % were infected with both protozoa. The frequency of infection according to sex; 2,7% of males were infected and 0.9% of females by Cryptosporidium spp, 12.7% and 11.5% by Giardia spp. and 1.5% and 0.9% by both parasites, respectively. Cryptosporidium spp. and Giardia spp. was frequent in children (under 12 year) than adults in both sexes, however, Cryptosporidum infections were most frequently diagnosed in children less than 12 years old and prevalence decreased with age. The prevalence of these protozoa in this community are lower than those reported by other studies, which is probably associated with the low density of the studied population. Studies analysis revealed that a male sex, children, loss of weight, impropal waste disposal, diarrhea and abdominal pain were correlated with the presence of these parasites, which indicate the importance of these factors in rural communities.

Abstract: Kombusha is benefit to people suffering from cancer due to increasing its acidity by the bacterium. This study to isolate and identify the bacterium samples from tea kombusha. Six acetic acid bacteria were isolated from traditional Kombusha fermentation of tea belong to the family Acetobacteraceae, genera Gluconacetobacter and Acetobacter. Acetic acid productivity yielded isolate No.1 that produced higher amount of acid. The isolate was catalase - Positive, oxidase – negative, strictly aerobic, Gram-negative rods, grow on yeast extract with 30% glucose and grow on glycerol variable on maltose but not methanol as carbon sources. The isolates oxidized ethanol of yeast kombucha to acetic acid therefore they were tentatively identified as Acetobacter species. The hight producer of acetic acid (11.2) was selected for identification by 16S rRNA gene sequences and phylogenetic analysis confirmed their position in the genes Acetobacter. On GYC agar, colonies are beige, round, convex, smooth and shiny and approximately 0.8mm in diameter after incubation at 28˚C for 4 days. The PCR product with size of about 1500 bp DNA was amplified. Based on the genotypic and phenotypic data, the isolate represent species of genus Acetobacter for which the name A.aceti is proposed.

Abstract: This work was carried out for the biosynthesis of antimicrobial substance that demonstrated inhibitory effects against microbial pathogenic from Streptomyces crystallinus, AZ-A151. The active metabolite was extracted using ethyl acetate (1:1, v/v) at pH 8.0. The separation of the active ingredient of the antimicrobial agent and its purification was performed using both thin layer chromatography (TLC) and column chromatography (CC) techniques. The physico-chemical characteristics of the purified antibiotic viz. color, melting point, solubility, elemental analysis, spectroscopic characteristics and chemical reactions have been investigated. This analysis indicates a suggested imperical formula of C15H30N2O10. The minimum inhibition concentrations "MICs" of the purified antimicrobial agent were also determined. The purified antimicrobial agent was suggestive of being belonging to Hygromycin-B, antibiotic produced by Streptomyces crystallinus, AZ-A151.

Abstract: In order to run the state estimator, it must be known that how the transmission Lines are connected to the load and generation buses. This information is called the network topology which also determine the bus level network model of a power system based on the te1emetered status of the circuit breakers at the substations. Since the breakers and switches in any substation can cause the network topology to change, a program must be provided that reads the telemetered breaker/switch status indications and restructures the electrical model of the system. Also, any errors in the te1emetered or manually updated status of the circuit breakers will lead to an incorrect bus level network model. This paper presents A pre-processing algorithm for detection of the statues of the suspected lines in electrical power system networks before state estimation solution. an algorihm is domenstrated,which handle the branch status error
