While only 8% them have poor knowledge.The majority of study group 94% take their management regularly, and more than half of them on fallow up regular.The study group have moderate knowledge about the items of knowledge and practice of foot care, only 28% of study them used blood testing measures to check up of blood glucose at home. The study recommended that, nurses and other medical staff have to include patient education in their plan of care, poster, hand book should be available for patient.

This study was aimed to investigate the capabilities of four applicablelighting regimes in inducing the onset of correct sexual maturity ofdeveloper layer pullets. The applied lighting regimes include natural daylight (NDΩ 12 hrs light), continuous lighting regime (CLR Ω 24 hrs light),boosted natural day length (BND Ω 16 HL: 8 HD) and 2-stages lightingregimes (2-SLR Ω 12 HL: 4 HD: 8 HL). The four lighting regime and 64grower layer pullets were randomly and evenly distributed to 16 similarexperimental pens within an open – type poultry house. The experimentalpens were equipped with all required facilities and prepared with an aid ofblack curtains to keep them light-tight.The experiment was commenced when the grower pullets were 10weeks old and continued for a week post the onset of laying. During thisperiod the experimental birds were kept restricted to the planned lightingregimes, got accessible to water and feed and vaccinated against theendemic diseases (New-Castle, Infectious Bronchitis and Fowl Pox).Data collected include: age, body weight, egg size and feed intake at pointof lay and a week after in addition to mortality rate throughout theexperimental period. The collected data were statistically analyzed to comeup with the following results: The developer pullets reflected at point of layshowed significantly (P< 0.05) controversial responses towards theexamined lighting regimes; The flock developed under CLR demonstratedthe youngest age at point of lay (131 days), the highest rates of feed intakeand body weight gain in addition to the smallest first egg size; The flockexposed to the ND responded significantly (P< 0.05) in a complete oppositemanner to that of the former group under CLR. In contrast to the responsepatterns of the former two flocks (CLR and ND), the interaction trends andmagnitude of the flocks confined to either the BND (16 hrs light) or the 2-SLR (20 hrs light) were moderate.With the exception of feed intake of the ND group, no other apparentchanges in performance pattern of the studied flocks were observed througha week post the onset of production. Further studies are stronglyrecommended for displaying the complete production features of eachexperimental lighting regime.

Scalable photocatalytic and antifouling applications for thin films can be attained by extending the light absorption ability of titanium dioxide (TiO2) from the ultra violet to the visible range through hydrogenation. In the process of hydrogenating TiO2 thin films, the effect of the dopant on the electronic band structure is studied. Fabrication conditions of time, pressure, and temperature are optimized and catalysts for diatomic hydrogen dissociation are examined. Morphologies from chemical etching and electron beam evaporation fabrication are compared in terms of the photocatalytic response to hydrogenation. The diffusion path and diffusion mechanism of the dopant also underpins hydrogenation for photocatalysis. The effect of crystal size and morphology on charge carriers is also described; films annealed at different temperatures result in different morphologies, which influences the response to hydrogenation. Employing these principles, antifouling properties of hydrogenated and unhydrogenated TiO2 thin films and TiO2 nanostructures grown on a titanium substrate and CuO covered copper substrate are demonstrated through methylene blue degradation. The implications from the photocatalytic studies are applied to a solar steam generation device. This device uses a TiO2 based spectrally selective solar absorber to achieve thermal concentration; the absorber is mounted between a transparent cover and floating insulation foam to reduce heat losses. The wick is inserted through the floating foam to pump the water to the topmost surface with capillary forces for steam generation. By coating the CuO foam with TiO2 nanoparticles, the wick self-cleans organic contaminants, restoring performance during the liquid propagation. The wettability of the wick is studied in terms of the contact angle as well as roughness. The morphology of the TiO2/CuO is discussed in view of this spectral selectivity; CuO pillars and blades interact with clusters of TiO2 nanoparticles. This work thus examines the fundamentals of TiO2 microstructure for solar applications.

Methyl tertiary butyl ether (MTBE) is the most commonly used gasoline oxygenate and is been reported as a global groundwater contaminant. Several remediation techniques exist for its treatment, although with inherent limitations, making further studies promising. Fly ash (FA), a waste material derived from the combustion of coal or heavy liquid fuel, has been reported to show promising results in its application for adsorption of selected materials in aqueous solution. In this study, raw-FA, acid treated-FA and metal oxide (silver, iron and aluminum) impregnated-FA were assessed for their adsorption efficiencies for MTBE treatment in contaminated water. From experimental results, only silver oxide impregnated-FA showed adsorption of 24% removal of MTBE in aqueous solution, while the other tested adsorbent materials showed <10% removal. The pH of the solution was found to have insignificant effect on MTBE removal when non-modified fly ash was applied. However, the more acidic solution showed better adsorption with the Ag2O impregnated fly ash. Also, Ag2O-FA showed optimum adsorption at 2 hours of contact, and using 50 mg of adsorbent.

This study was carried out to isolate and identify Gram- positive andGram-negative bacteria which contaminate food of meat origin.Ninety samples of cooked, ready-to-eat Sandwiches (Beef-Burger,Shawarma, Kebab and Agashi) collected from different street food venders,samples were cultured on MacConkey‘s, nutrient and blood agar. Isolates,were purified and identified to species level according to theirmorphological and biochemical properties. A total of 76 isolates wereobtained,50 of them were Gram-negative bacteria which identified:Klebsiella pneumoniae (22%), followed by Enterobacter spp (15%),Serratiamarcescens(11%),Hafnia alvei (7%),Campylobacter spp(2%), Citrobacterfreundii (2%) and Pseudomonas aeruginosa and Proteus vulgaris (1%). 26isolates were Gram-positive bacteria which identified:Staphylococcus spp(11%), Bacillus cereus(6%), Listeria monocytogenes (3%), Bacillusmycoides(2%), Brochothrix spp(2%), Kurthia gibsonii (2%), Enterococcusspp (2%) and Micrococcus spp(1%).The study revealed that foods of meat origin are often contaminated withbacteria. The presence of Klebsiella pneumoniae, Enterobacter cloacae,Campylobacter spp, Staphylococcus spp, Bacillus cereus and Listeriamonocytogeneswas of medical significance. The presence of theseOrganisms in meat foods should receive particular attention, because theirpresence indicate public Health hazard and gives a warning signal for thepossible occurrence offood borne diseases
