ABSTRACT: The seeds of Punica granatum fruit from Nigeria and Saudi Arabia were analyzed for nutritional and anti-nutritional composition using standard analytical methods. The results obtained were studied. The results obtained show that there were significant differences (p<0.05) in percentage ash, moisture, crude lipid, crude protein, crude fiber, available carbohydrate and the energy value .Elemental analyses show that magnesium is the most abundant elements in the seeds of both countries Nigeria and Saudi Arabia (5650mg/100g) and (1140.1mg/100g) respectively, this may be due to its availability soil where it was grown, while copper and zinc are the least abundant. The result of anti-nutritional analyses indicate significance difference (p<0.05) in hydrocyanic acid, nitrate, soluble oxalate, phytate and tannin. The anti-nutrients to nutrients ratio indicate the availability of some minerals. The study show that differences and similarities in nutritive contents with respect to Protein, Fiber, Fat / Lipids, Calcium, Iron magnesium, Sodium, Potassium, etc in the two samples may be due to climatic condition, genetic factor, mode of cultivation, topography and other factors. Considering the nutritional and anti-nutritional profile of the two samples, it can be conclude that the seed is a very good source of some nutrients which if utilized properly would assist in providing some of these nutrients to the people in the society; this may assist in combating the problem of malnutrition in Nigeria and Africa in general.

Abstract: River courses on the Basement Complex are often characterized by a narrow strip of alluvium called “fadama”. Several fadamas abound all over Kaduna State, and they have become a source of livelihood for many farmers who depend on the swampy conditions for both wet season and dry season crop production. In order to assess the groundwater potential of a fadama in Kaduna State for irrigation, 20 Vertical Electrical Soundings (VES) were made and the existing borehole data were obtained. Geophysical investigation results were found to be consistent with the interpreted drilling data. With good recharge capability, shallow depth to water table (generally within 1-10m), tested yield of between 1.3 to 10m3/h, permeability range of 0.13 to 0.48 m/day, and an estimated groundwater storage capacity of about 23.6 million m3, there is indeed a great groundwater potential for irrigated farming, and possibly rural water supply in the fadama.

Abstract: There have been a plethora of seminal studies regarding teaching reading strategies to ESL and EFL learners, but teaching reading strategies to ESP students has been given scant attention in language teaching. The guiding theme of this research was prompted by awareness of marketing university students’ problems understanding business texts in English. In other words, this study was undertaken to examine the efficacy of using two reading strategies (i.e. graphic organizer and marginal L2 glossing) in ESP students’ reading comprehension. The Students who participated in this study were randomly assigned to “graphic organizer” treatment, “marginal L2 glossing” treatment, and a control group. The result of this quasi-experimental study revealed that both treatment groups outperformed the control group in the reading comprehension posttest. Furthermore, there was a significant difference between the means for the graphic organizer and marginal glossing groups in favor of the graphic organizer group. In other words, the result of this study indicated that the graphic organizer group performed significantly better than the other two groups in reading comprehension of business texts. The Students in the graphic organizer group were provided by a “structured picture” of the concepts of the texts.

ABSTRACT: The study was under taken to study the emotional intelligence of children of working and non-working mothers. The sample of the study comprised of 100 children (50 children of working mothers and 50 children of non-working mothers) selected randomly from all Govt. High and Higher Secondary Schools of zone Shopian. Emotional intelligence scale by Hyde et al was employed for the collection of data and ‘t’ test was used for the analysis of data. Bar diagrams and Line graphs were drawn to make the results transparent. The results of the study highlight that children of non-working mothers are more emotionally intelligent than children of working mothers. Children of working and non-working mothers show significant difference in self-awareness, empathy, self-motivation, emotional stability, managing relations, integrity, self-development and altruistic behaviour. Children of non-working mothers have been found clear in their priorities, pay more attention to the worries and concerns of others. They are found to be friendly, sociable, helpful and skilful in dealing with people. They are found to be more responsible, more comfortable to novel ideas and new information. They face boldly good and bad situations. They are more aware of their weaknesses, are more co-operative, helpful, outgoing and democratic. They are better able to encourage people to take initiative. They can handle conflicts around them more intelligently than the children of working mothers. No significant difference was found in value orientation and commitment between children of working and non-working mothers.

Abstract: This study was designed to evaluate the effect of the most prevalent and highly virulent coccidial infection (caecal coccidiosis) as well as anticoccidial vaccination on haemagglutinating antibody titers of Newcastle Disease virus (NDV) and Infectious Bursal Disease Virus (IBDV) antibody ELISA titers resulted from vaccination program in broiler chickens. For this purpose, 180 day old Hubbard broiler chicks were randomly divided into 3 equal groups (G1, G2 and G3), each of 60 chicks. At 3rd day of age birds of G1 was vaccinated with anticoccidial vaccine via crop, and at 14th day of age birds of G2 was infected with high dose (50000) of sporulated E. tenella oocysts intra crop, while birds of G3 remain as control (Non coccidia vaccinated or infected). At 14th, 21th and 28th days of age, mean HI antibody titers of G3 were higher than G2 and G1 groups. At 21th and 28th days of age, mean HI antibody titers for NDV as well as mean ELISA antibody titers for IBDV of G2 were significantly lower than other groups (p≤0.05). At 35th and 42th days of age HI titers of G3 and G1 were higher than G2, but the differences were not significant (p>0.05). The mean HI antibody titers for NDV as well as mean ELISA antibody titers for IBDV of G1 had non-significant lowering values than those of G3 at all ages (p>0.05). It was concluded that coccidial infections as well as anticoccidial vaccination are able to reduce humeral immunological reactions of broiler chickens as indicated by the significant reduction in mean HI antibody titers for NDV and mean ELISA antibody titers for IBDV as well as the significant lowering in the protection percentage against challenge with VVND and virulent IBDV in these chickens. Since this effect was more prominent in infected group than in anticoccidial vaccinated one, in the cases of coccidiosis outbreaks in the farm with higher levels of coccidial infections, involvement of mixed virulent species (E. tenella, E. necatrix, E. acervulina, E. maxima….. ect.) and other environmental stressors, more severe and prolonged immunosuppresion are expected.

Abstract: This study reports on pathogenic microorganisms associated with flies within Uyo metropolis during the wet season. Flies were collected from ten (10) different sites within Uyo metropolis in the month of July. The sites were characterized into institutional areas, market areas, congested areas and affluent areas. The pour plate method was employed for the determination of microbial load of samples using standard methods. The microbial counts of the various fly samples analyzed for the months of July and August showed that the total heterotrophic bacterial counts ranged from 4.8 x 104 cfu/g to 18.9 x 104 cfu/g. Total coliform ranged from 4.9 x 104 cfu/g to 13.0 x 104 cfu/g, Salmonella/Shigella count ranged from 4.1 x 104 cfu/g to 2.16 x 104 cfu/g. Vibro count was 2.6 x 104 cfu/g to 18.3 x 104 cfu/g, Staphylococcus count was 2.5 x 104 cfu/g to 3.2 x 104 cfu/g and 1.1 x 104 cfu/g to 1.9 x 104 cfu/g for fungal count. For the month of August, the total heterotrophic bacterial count ranged from 4.6 x 104 cfu/g to 17.4 x 104cfu/g, 8.2 x 104cfu/g to 15.3 x 104 cfu/g, for total coliform, 5.4 x 104 cfu/g to 15.6 x 104cfu/g for Salmonella/Shigella count, 2.7 x 104cfu/g to 14.1 x 104cfu/g for Vibro count, 3.1 x 104cfu/g to 5.4 x 104cfu/g for Staphylococcus count and 1.4 x 104cfu/g to 3.1 x 104cfu/g for fungal count. The frequency of occurrence of the isolates showed that bacteria (57.8%) were more predominant than fungi isolates (42.2%). It showed that Salmonella spp., [18 (34.6%)] was the most prevalent bacterial isolates. This was followed by Shigella spp. [10 (19.2%)], Vibrio cholerae [8 (15.4%)], Vibrio parahaemolyticus [6 (11.5%)], Escherichia coli [4 (7.7%)], and Staphylococcus aureus [3 (5.8%)]. Pseudomonas aeruginosa [1(1.9%)], Bacillus spp., [1(1.9%)] and Aeromonas spp. [1 (1.9%)] were less prevalent. The frequency of occurrence of fungal isolates showed that Penicillium spp. [16(42.1)] was most prevalent fungi isolates among the flies studied, followed by Aspergillus fumigatus [10(26.3%)], Aspergillus niger [7(18.4%)] and Verticillium spp., [2 (5.3%)] while Paecilomyces spp. [1(2.6%)], Mucor spp. [1(2.6%)] and Aspergillus spp. [1(2.6%)] were less prevalent. This study has so far established that flies pose a possible health risk to both man and his environment. Thus, the introduction of strict public health measures is however needed in homes, public places and the environment at large.

The objective of this study is to isolate, identify and evaluate the effect of Klebsiella pnemoniae in relation to the catfish, by isolating the microorganisms present on the catfish skin and intestine. To find out if Klebsiella pneumoniae bacteria isolate can survive in the fish (immunity of fish) and observation of the public health hazard that bacteria i.e. test organism and natural flora exposes the people to, samples of catfish were analyzed using standard techniques. The physicochemical analysis showed that there were changes in the pH, the temperature and the dissolved oxygen of the water samples. The distributions of the bacteria species isolated from the catfish intestine and on the skin showed that Klebsiella pneumoniae [12(25.0%)] was the most predominant bacteria isolates. This was followed by Enterococcus feacalis [9(18.6%)], Staphylococcus aureus [7(14.6%)], Escherichia coli [6(12.5%)], Citrobacter ferundii [5(10.4%)], Pseudomonas aeruginosa [5(10.4%)], and Bacillus subtilis [4(8.3%)]. It also showed that Enterococcus feacalis and Citrobacter ferundii were absent in all the skin samples of the catfish but present in all the intestines. Klebsiella pneumoniae was present on all the skin and intestines of the catfish samples. Escherichia coli were present in all the skin and intestine except for skin of the catfish samples in Experiment 1. Bacillus subtilis was only present in the skin of the catfishes used as control. Staphylococcus aureus was absent in all the intestine of the catfishes samples but present in their skins. Pseudomonas aeruginosa was absent in all the samples except for the intestines of the catfishes used as control and those in experiment 2. Generally, Klebsiella pneumoniae inoculated into catfish Clarias gariepinus presented to be virulent in the fishes leading to shedding of skin patches and fading of colour on skin from black to faint black. The findings of this study showed that Klebsiella pneumoniae may cause an infection in catfish and can act as a vector of human pathogen. Furthermore, other bacteria were isolated which may be resident flora of the catfish. Therefore, it is important to handle fishes with proper hygiene and best public health measures since fishes are used for consumption.

Abstract: Infertility is the biological inability of a man or woman to contribute to conception. Chlamydia trachomatis is the most implicated organism in infertility. The objective of our study was to determine the prevalence of recent Chlamydia trachomatis infection by antigen detection in couples with various forms of infertility. Three hundred and fifteen (315) subjects comprising 108 (24.3%) males and 207(75.7%) females, attending fertility clinic at Federal Medical Center, Abeokuta. High vaginal swabs and semen were collected and processed for microscopy; semen was analyzed for count and morphology following standard methods. Chlamydia trachomatis antigen was tested on all samples using an immunochomatographic rapid test kit. Overall prevalence rate of Chlamydia trachomatis was found to be 9.8%. Prevalence rate of Chlamydia trachomatis was highest in age group 31-40 years of age, when compared to other age groups. It also showed that Chlamydia trachomatis antigen was more prevalent among females (11.6%) compared to their male counterparts having 6.5% positivity. Antigen positivity was highest in subfertile group (26.3%) and lowest in secondary infertility group (8.3%). It was also higher in Azoospermic male subjects than Oligozoospermic or normal ranged subjects. From the findings of this study, it can be concluded that there was no strong independent evidence showing any association between Chlamydia trachomatis antigen positivity and infertility in couples at Abeokuta, Ogun State, Nigeria, although more case controlled studies are needed to further investigate any relationships between infertility and recent Chlamydia infection in our environment. However, there is strong evidence that adult couples in the prime of their reproductive age pose the risk of exposure to Chlamydia trachomatis. Thus, concerted efforts to address possible risk factors which are proxies to acquisition of Chlamydia trachomatis, and better health seeking behavior by couples intending to have children will likely reduce the burden of infertility in Nigerian couples.

Abstract: Freshwater fish, Colisa fasciatus caught from lake was studied for toxicity and biochemical parameters in reproductive cycle and was compared with control fish. Fish liver was dissected out and analyzed for various biochemical parameters like total protein, total glycogen, nucleic acids (DNA and RNA). Cadmium Sulphate was lethal to 0, 50 and 100% of test fish which produce absolute mortality for four different time intervals. Sub-lethal exposure of Cadmium Sulphate for 30 days caused significant (p>0.05) alternation in total protein, total glycogen nucleic acids (DNA and RNA) and body weight in both testicular cycle and ovarian cycle of C. fasciatus.

Abstract: Avian influenza virus usually refers to influenza A viruses found chiefly in birds, but infections can occur in humans. The risk is generally low to most people, because the viruses do not usually infect humans. However, confirmed cases of human infection have been reported since 1997by H5N1 subtype. In the current study, a highly pathogenic avian influenza subtype H5N1 was isolated and confirmed by PCR and sequencing. Sequence analysis revealed some degree of heterogeneity withers on the level of HA or HI. The poly basic amino acid sequence of the isolated virus was similar to the highly pathogenic strains of H5N1 (PQGE (R/G/K)RRKKR↓GLF) with some strains having differences in the 5th amino acid were the R residues were substituted with either G or K. phylogenetic tree revealed that 3 out of the 7 studied samples were greatly homologues while the other 4 samples were widely heterologous.

Abstract: This research aims to determine rates of adoption and continuation of some selected innovations (Wheat Seds1, El-Gorma Watermelon, Sprinkler Irrigation System, and Sugar Beet) and to determine perceived barriers to adoption and diffusion of these selected innovations from farmers' point of view. In order to achieve these objectives, an empirical study targeted all farmers of The Third Village in Darb El-Arbaeen area, Paris District, The New Valley Governorate. Data were collected during January 2008 through personal interviews with farmers using a questionnaire form constructed and pre-tested to fulfill the study objectives. Frequencies and percentages were used for data processing and presentation. Results showed that high price of fertilizers, its unavailability and high shelling of grains were the most important barriers to the adoption and diffusion of Wheat Seds1. Lack of farmers experience and lack of extension activities were the most important barriers to the adoption and diffusion of El-Gorma Watermelon. Barrier to the adoption and diffusion of Sprinkler Irrigation System were: (1) it requires more labor, (2) it requires more effort, time, and money, (3) losses in yields caused by transferring pipes, (4) damage of pipes, (5) type of soil is not suitable, and (6) prefer surface irrigation system. Barriers to the adoption and diffusion Sugar Beet were: sugar factory did not implement its promises, lack and late arrival of transportation means, prefer wheat cultivation and have no experience about it.

Abstract: In vitro multiple shoot regeneration of Salvadora oleoides has been accomplished on MS medium utilizing shoot tip explants. Direct multiple shoots differentiated with in 5 weeks when explants were cultured on MS medium containing Kn and BAP individually as well as in combination with auxins. Among various concentrations of cytokinins tested, maximum shoots induction from shoot tip explants was obtained on MS medium supplemented with 2.5 mgl-1 BAP individually. 2.5 mgl-1 BAP+0.25 mgl-1 NAA gave better results than all other treatments used in combinations. The regenerated shoots were rooted on MS full strength medium augmented with 1.0 mgl-1 NAA. The regenerated plantlets were established successfully under field conditions.

Abstract: Pigeon pea stalks, agricultural residues from Gezira state –Sudan were pulped with alkaline sulphite, alkaline sulphite anthraquinone (AS-AQ) and alkaline sulphite anthraquinone with methanol- ASAM. The objective of present work was to optimize alkaline processes for pigeon pea stalks and to reach delignification suitable for bleaching. With active alkali charge 16-19% as Na2O demonstrated total yields 50.4-52.7% viscosities 833-886 ml/g for alkaline sulphite process. AS-AQ produced pulps with total yields 40.2-50.1%, viscosities 722-932 ml/g and brightness 27-44% when active alkalis charges 16-20%. ASAM pulping gave good to excellent physical properties, total yields 47.6-51.7%, screened yields 46.9-48.3%, viscosities 981-1032 ml/g, when active alkali charge 15-19% and methanol 15% were applied.
