MAGNETIC FIELDS CAN BE MODIFIED TOOL FOR SOME BIOLOGICAL PARAMETERS AND CHARACTERS OF MICROORGANISMS
No full textThis review be points to the investigations concerning the effects of magnetic fields (MFs) on microorganisms e.g. bacteria and fungi. Those exerted by weak DC and low-frequency/low-intensity AC MFs. At the first of the nineteenth century, the physical mutagenesis e.g. radiation, hot/cold, electrical field (EF), magnetic field (MF). etc., were inspired for enhancing or modifying their biological behavior. The MF was used to study their influences on all living cells. While most applications were upon bacteria as prokaryotes and yeast (Saccharomyces cerevisiae (S.c), used as a model of eukaryotes. So, the various studies since 1990 have been appeared that low intensity of MF possess the brightness side for regulating biological systems. The low intensity of MF (0.01 ‹ T›1.0) was so effect that it decreased the cell population or inhibited the growth. While the exposure the S.c to high intensity was increased cell population within 1.5 T. The effect of MF on living cells depends on main reasons; 1) Intra-structure of the cell as chemicals contents that governed the conductivity of solution especially in the membranes (the first protective line), and genetic background.2) Outer structure which surrounded the cells (pH). 3) The density flux of MF, and 4). The status of MF, solid or correlated with frequencies (Hz). The MF play important role to regulate the clock-control gene. Therefore, the MF might be useful tool for change the pathway production belong biological system
INVESTIGATION OF SUGAR CANE BAGASSE ASH AS A BINDING MATERIAL FOR THE CONSTRUCTION INDUSTRY
No full textSugarcane bagasse ash (SCBA) is a byproduct of the sugar factories produced after burning sugarcane bagasse in the production of electricity. The sugarcane bagasse is produced after the extraction of all economical sugar from sugarcane. The disposal of this material is a common environmental problem in factories producing electricity from sugarcane. In Kakira Sugar Limited (KSL) about 61,000 tons / yr. of SCBA is produced and only about 30,000 tons / yr of this is utilized, and the remaining is damped which becomes an environmental hazard. This research was, conducted to examine the potential of bagasse ash as a cement replacing material in construction industry. Bagasse ash samples were collected from KSL and its chemical properties were investigated. The compressive strength of mortars containing ordinary Portland cement and SCBA in proportions of 0%, 10%, 15%, 20%, 25%, 30% and 40% as a cement replacement were investigated. Three replicates with the bagasse ash replacing ordinary Portland cement in the above mentioned proportions were prepared and tested. The results showed that ordinary Portland cement can be replaced by SCBA up to 20% without affecting the compressive strength of the mortar at a test age of 28 days. These findings suggest that replacement of cement with SCBA could results in the reduction in cost of construction
INFESTATION STUDY OF ECTOPARASITIC FAUNA ON SOME DOMESTIC ANIMALS IN AYEDIRE LOCAL GOVERNMENT AREA OF OSUN STATE, NIGERIA
No full textThe zoological and epidemiological examination of Ectoparasite on some domestic Animals was carried out under open laboratory survey. 100 numbers of Sheep, 100 number of Dogs, 100 number of Goats, and 100 numbers of Cattle were examined for infestation. Structured questionnaire was administered in five (5) sampled communities’ areas within the study area. The villages were purposely chosen due to their proximity to the forest zone. The questionnaire was designed to collect information on the infestation rate of Ectoparasite fauna on some domestic animals in the Local Government Area. A total of hundred respondents were randomly selected and interviewed. The study revealed that the domestic animals were infested by the Ectoparasite in the communities. Ticks infestation reached its peak in the month of November 2009. The study revealed that 30%, 29%, 21%, and 20% of goats, dogs, sheep and cattle were infested respectively. In cattle, low infestation was recorded. The Ectoparasite examination was mainly on members of order Anoplura, order Siphonaptera and sub-order Ixodiodea. Two species of Amblyomma, Rhipicephalus and Boophilus were recorded while only a species of Hyalomma Haemaphysalis, Ctenocephalisdes were observed. Also two species of Anoplura that are of Linognathus vituli and Heamatopinus suis were observed during the survey. In the survey, infestation of fleas was mostly high between the months of June to September 2009. Examination of free and penned ranging animals was also observed. The survey recorded 21% of tick’s infestation on sheep. The examination revealed that the predilection site of tick’s infestation could be sighted mostly on neck region while that of the fleas is found at the trunk region

THE EFFECTIVENESS OF BACTERIAL CONSORTIUM IN BIOREMEDIATION OF TEXTILE WASTEWATER CONTAINING DYES REMAZOL BLUE
No full textThe Research was focussed on the effectiveness of a bacterial consortium to the bioremediation of industrial waste water containing dye textiles blue Remazol, in which it has successfuly been done. The aim of this study was to determine the effectiveness of consortium of bacteria on bioremediation of textile waste water which contains Remazol blue dye. The process was to clearly find out how the bacterial consortium’s capability in degrading the textile industry wastewater in which the blue dye Remazol is contained. The research was carried out experimentally using Randomized Complete Block and some factorial treatments. These two treatment factors comprises of two types, they are: a). The type of microbial consortium consisting of the Consortium of Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp.; consortium of bacteria Bacillus licheniformis, B. pumilus, B. subtilis, Pseudomonas putida, and Nitrosomonas sp and a consortium of Paenibacillus amylolyticus bacteria, Nitrosomonas, B. circulans, and B. pumilus and b). The factor of the consentration of Remazol blue on industrial wastewater. This particular textile wastewater containing Remazol blue with concentrations in which containing 200 ppm, 1000 ppm and 2500 ppm. The parameters of the study was BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid) and decolorization efficiency. The data has been analyzed quantitatively. The results have shown that Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp. became the most effective consortium in degrading remazol blue in textile wastewaster. The evidence revealed that the higher concentration of remazol blue on wastewater, the smaller degradation effectiveness was resulted by the consortium. The consortium of Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp. was able to degrade textile industrial wastewater with a maximum concentration of remazol blue up to 2500 ppm and the bacterial consortium was able to decolorize of Remazol blue that reaching to 84.9%; reducing the levels of Biochemical Oxygen Demand (BOD) to 57.9%; reducing Chemical Oxygen Demand (COD) of 37.7%; and finally reducing Total Suspended Solid (TSS) more or less of 52%
LANDSLIDE VULNERABILITY AND ITS IMPACT ON LOCAL COMMUNITY: A GEO-SPATIAL ANALYSIS OF DISTRICT MANDI, HIMACHAL PRADESH, INDIA
No full textLandslide is the downward movement of slope debris along a surface where shear failure occurs. This is an event which occurs in the process of geomorphological transformation resultant to an event of extensive magnitude causing significant physical damage or destruction, loss of life and drastic change to the environment. In the Himalayan region landslides occur every year, causing casualties and large economic damage. However, the magnitude of hazard impact can be reduced if its likelihood is recognized before any type of land development activity. Presently, landslide mapping, hazard assessment and risk evaluation are important goals for scientists, planners, administrative decision makers and land developers. In this context, present study seeks to analyse the spatial pattern of vulnerability to landslide and impact on existing communities of the study area with the help of advance geo-spatial technology. A GPS based ground survey has also been conducted to verify the results
NEUTRALIZATION OF DYEING INDUSTRY WASTEWATER AND SLUDGE BY FIXATION OF POLLUTANTS IN VERY HIGH QUALITY HEU-TYPE ZEOLITIC TUFF
No full textTreatment of dyeing industry wastewater of pH 7.5 with very high quality zeolitic tuff and coagulants, resulted in clear water of pH 7.2, free of odours and improved quality characteristics (colour, suspended particles, COD: Chemical Oxygen Demand, P2O5, NO3-, Cr) by 74 to 98%. The very high quality zeolitic tuff is 3 to 60% more effective than the coagulants, concerning COD, Cr and NO3-. The treatments produced sludge (using coagulants) and zeo-sludge (using very high quality zeolitic tuff and coagulants). The zeo-sludge is odourless and cohesive. The leaching by deionised water of sludge reached values up to 100% for the quality characteristics, while that of the zeo-sludge reached significantly lower values (only up to 18%). The chemical composition of the seepage water from the zeo-sludge proved the fixation of pollutants, such as NO3- and Cr by the very high quality zeolitic tuff
