Abstract: Zooplankton organisms occupy a central position in the food webs of aquatic ecosystem. They do not only form an integral part of the lentic community but also contribute significantly, the biological productivity of the fresh water ecosystem (Wetzel 2001). The importance of the Zooplankton is well recognized as these have vital part in food chain and play a key role in cycling of organic matter in an aquatic ecosystem. In the present study the total Zooplankton density exhibited a single peak during March. However, a sudden increase was noticed in the month of October which continued till March. This increase is attributed to the settling of rain water return of favourable conditions in post monsoon period.In the present study total Zooplankton comprises of 4 groups: Protozoa, Rotifera, Gladocera, Copepode. Out of this group Rotifera is the dominant group and the order of dominance is as Rotifera > Cladocera > Copepode > Protozoa. [Researcher. 2010;2(9):1-9]. (ISSN: 1553-9865).

ABSTRACT: Two experiments were done to study the effect of partial replacement of berseem hay by ensiled and dried sugar beet tops on the performance of growing rabbits. In the first one, 8 mature male NZW rabbits with an average body weight of 2.5 kg and 8 months old were used to determine digestibility coefficients and nutritive values of berseem hay (BH), ensiled sugar beet tops (SBTS) and dried sugar beet tops (SBTH). In the second one, 50 NZW growing rabbits of 60 days of age were used in a complete randomized design experiment with five treatments. The first group fed commercial rabbit diet including 40% BH (control diet), while in the other groups 50 or 100% of BH was replaced by SBTS and SBTH throughout the 70 days of experiment. Results of the first experiment showed that the contents of OM and CF were lower and NFE and ash content were higher in SBTS and SBTH compared with of BH. While, CP was higher in SBTS and lower in SBTH than that of BH. The digestibility coefficients of DM, OM, CF, EE and NFE were significantly higher (P<0.05) for both SBTS and SBTH compared with BH. However, BH had significantly (P<0.05) the highest TDN and DE values followed by SBTS, while SBTH had the lowest values. While, CP digestibility and DCP value of SBTS were significantly higher (P<0.05) than that of BH and SBTH. In the second experiment showed that calculated composition was nearly similar for the different diets except OM and CF decreased and ash increased in diets contained SBTS and SBTH compared with commercial diet. Diet contained 100% SBTS showed significantly (P<0.05) the highest digestibility coefficients of DM, OM, CP, EE and NFE and DCP value. While, commercial diet revealed the highest CF digestibility and TDN and DE values. Rabbits fed 100% SBTS diet had the highest TVFA's and NH3-N concentrations and the lowest pH value. Rabbits fed 100% SBTS diet showed significantly (P<0.05) the highest final body weight, total and daily weight gain and the lowest average daily and total DM intake and DM/kg gain, however, those fed commercial diet had the opposite trend. Rabbits fed commercial diet showed significantly (P<0.05) the highest feed cost and feed cost/kg gain, however, rabbits fed 100% SBTS diet showed significantly (P<0.05) the highest total and net revenue and net revenue improvement. Rabbits fed 100% SBTS showed significantly (P<0.05) the highest slaughter weight, carcass weight, dressing percentage, meat weight and percentage and the contents of CP, EE and ash and lowest DM content in meat, but, those fed commercial diet had the opposite trend.

Abstract: Analysis is a strategic planning method used to evaluate the Strengths, Weaknesses, Opportunities, and Threats involved in a project or in a business venture. It involves specifying the objective of the business venture or project and identifying the internal and external factors that are favorable and unfavorable to achieving that objective. SWOT analysis provides a framework for visioning by helping the planners to identify and priorities the organization’s GOALS and to further identifies the strategies of achieving them. SWOT analysis is a technique to analyze the Strengths, Weakness, Opportunity and Threats of a decision, problem ad place etc. In community development or urban planning SWOT is often used at community meeting to structure conversations about projects carrying out this analysis often illuminates what needs to be done and puts problems in to prospective. A tool that identifies the Strengths, Weaknesses, Opportunities and Threats of an organization. Specifically, SWOT is a basic, straightforward model that assesses what an organization can and cannot do as well as its potential opportunities and threats. The method of SWOT analysis is to take the information from an environmental analysis and separate it into internal (strengths and weaknesses) and external issues (opportunities and threats). Once this is completed, SWOT analysis determines what may assist the firm in accomplishing its objectives, and what obstacles must be overcome or minimized to achieve desired results.

Abstract: The analysis of the rotor aerodynamics is based on the combined blade element and momentum theory and the content is directed toward the physics of power extraction by wind turbines at both the near and far wake regions. The near wake is the area just behind the rotor, where the properties of the rotor can be discriminated, so approximately up to one rotor diameter downstream and the far wake is the region beyond the near wake, where the focus is put on the influence of the wind turbines in farm situations. A wind turbine extracts energy from the wind by producing a step change in static pressure across the rotor-swept surface. Turbine rotor is the component which exhibits the largest proportion of fatigue failure and the centrifugal and gravity loads are primarily responsible. The generalized Fokker-Planck equation which is a partial differential equation satisfied by the probability density function is employed in modeling the turbine power. [Researcher. 2010;2(9):31-40].

Abstract: The lift force and vibration performance of a NACA-230 airfoil with a ‘bionic skin’ (metallic version of the butterfly scale) were experimentally investigated. Attention was initially directed to this problem by studies indicating a better lift, maneuver, vibration and noise performance of flying butterflies, covered with scales. Results indicated that the ‘bionic skin’ of an oscillating rotor blade increased the lift force by a factor of 1.15, reduced both the damping coefficients by a factor of 1.23, and the vibration by a factor of 1.17. The modification of the aerodynamic effects on the rotor blade was due to an increase of the virtual air mass, which influenced the ‘bionic skin’. The air cavity of the skin increased the virtual air mass by a factor of 1.2. The interaction mechanism of a ‘bionic skin’ with a flow and a sound wave was described. [Researcher. 2010;2(9):41-49].

Abstract: Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants in water. The photocatalytic degradation of two azo dyes, monoazo dye Acid Orange 10 (AO10) and diazo dye Acid Red114(AR114) present in wastewater were studied. Homogeneous photocatalytic degradation of the two azo dyes with UV/H2O2 process was investigated. The rates of disappearance of the two azo dyes were monitored spectrophotometrically at the visible maximum absorption wavelengths. It was found that the rate of decolorization rises by increasing the initial dosage of H2O2 up to a “critical” value at which it is maximum and beyond which it is inhibited. The rates of reactions follow pseudo-first-order kinetics. Also heterogeneous photocatalytic degradation of the two azo dyes with UV/TiO2 (titanium dioxide) interface was investigated. The photocatalytic degradation rate depends on dye structure, dye concentration, TiO2 concentration and pH of the medium. The mechanism of the photodegradation process under UV-visible light illumination involves an electron excitation into the conduction band of the TiO2 semiconductor leading to the generation of very active oxygenated species that attack the dye molecules leading to photodegradation. Photocatalytic activity of TiO2 was examined by focusing on its enhancement by electron scavengers in the photocatalytic decomposition of the two azo dyes. The electron scavengers employed was inorganic oxidant such as H2O2, adequate dose of H2O2 led to a faster degradation of the two azo dyes in the TiO2 photocatalytic system. The fast decolorization of monoazo dye (AO10) than diazo dye (AR114) is an indication that, the number of azo and sulphonate groups in the dye molecule may be a determining factor for increasing the degradation rates.

ABSTRACT: Ogi is a popular cereal meal consumed mainly in the western part of Nigeria. Despite its safety and health benefits, its consumption is dwindling. Like other lactic acid fermented foods, ogi is a good source of lactic acid bacteria (probiotics). Probiotics have been reported to have some benefit in the prevention and treatment of some diseases such as gastrointestinal disorders including diarrhoea and dysentery. Metabolic disorders such as lactose intolerance, sucrase and maltase deficiencies can also be managed by probiotics. They favorably modulate immunity in some circumstances and have anticarcinogenic effects, regulate hypercholesterolemia. The use of probiotics to recolonize the vagina to prevent sexually transmitted diseases like gonorrhoea, syphilis, candidiasis and HIV has also been documented. These claims provide a strong rationale for increased consumption of ogi, particularly among immunocompromised populations such as the elderly or the convalescent. Probiotics enhance the immune response, which would in turn increase resistance to immune-related diseases. ogi is very cheap and easy to prepare. If the potential of ogi and lactic acid bacteria (LAB) could be adequately utilized it will reduce the pressure on the use antibiotics and hence reduce the rate of bacterial resistance to antibiotics.

Abstract: Parachanna obscura, the African snakehead fish, were randomly selected and subjected to parasitologic investigations. A total of three hundred and forty specimens were monthly obtained over a period of one year. Helminth infections was observed to have a prevalence of 5.9% which accounts for twenty of the specimens to be infected with gastrointestinal helminth parasites. Parachanna obscura harboured two nematodes, Procamallanus sp (Spirocamallanus) and Contracaecum sp and a trematode, Clinostomum metacercaria. A sum total of twenty two helminthes was recovered from the fish. The male specimens (229) recorded a lower rate of infection (5.2%) than the females (111) which recorded a prevalence of 7.2%. The overall worm burden were low and independent of sex and size of the fish. [Researcher. 2010;2(9):78-84]. (ISSN: 1553-9865).

Abstract: Ten genotypes of rice ( Oryza sativa L.) including some lines collected from the farmers fields in Abia, Ebonyi and Imo States of South Eastern, Nigeria, were used for the experiment. The seeds were grown in the early seasons of 2006 and 2007 at the Teaching and Research farms of the Federal University of Technology, Owerri and used for assessing their yield and Physicochemical characteristics. Moderate to high variation was observed for all the characters studied. Number of tillers per stand varied most having a coefficient of variation of 20% followed by percentage fibre (18. 7%) indicating a scope for selection of these traits among the lines evaluated. Conversely, percentage amylose (1.9%), grain length (4. 4%) and percentage protein (5 .4 %), had lower values for coefficient of variation suggesting that the variation were more genetically similar in these attributes. Heritability in the broad sense estimates revealed that grain length had the highest heritability (93. 2%) followed by number of days to anthesis (90 .7%) while number of spikelets/ panicle (32.3%) and number of tillers / stand (49.03%) were the least. The physical characteristics of the grains divided the lines investigated into long slender, long bold and medium bold sizes and shapes. Among the lines however, Mass and Wita 4 combined high numbers of tillers/ stand, high percentage fertile spikelets and high number of seeds per secondary branch of panicle and long slender grains. On the other hand, Sipi 692033 and NERICA 1 had higher percentage protein and amylose with long grains. [Researcher. 2010;2(9):85-90]. (ISSN: 1553-9865).
