Prevalence and Risk Factors of Malaria in Kano Metropolis, Nigeria

Malaria has been the focus of multiple declarations, and a range of targets has been set since the beginning of the millennium. Poor people are at increased risk of both becoming infected with malaria as well as becoming infected more frequently. Malaria is also a major contributor to deaths among hospital inpatients in Africa. The purpose of this research is to employ geospatial techniques to map out areas that are vulnerable to malaria breeding vectors using weighted multi-criteria decision analysis to determine the risk levels within the study area and to determine the factors influencing the population at risk of malaria with a view to providing an effective malaria management. Malaria incidence records were used to determine the incidence rate of the disease from 2014 – 2016 and the rate of severity and total confirmed cases of the disease occurrence during the study period. Malaria risk map, which was produced through the integration of malaria hazard map, vulnerability map and elements at risk map, was used to determine the most susceptible areas to malaria attacks in the study area. The results showed about 87% of the entire study area being at high risk of malaria attack. It is observed that there is an increasing trend of malaria cases in the study area despite its variability over the years. It can be concluded that the study area as a whole is prone to malaria infestation and this requires immense attention in order to mitigate the scourge of the disease and its vector. It will be cost effective if GIS and remote sensing could be integrated in monitoring and early warning system in the ongoing malaria control and prevention activities especially in Nassarawa and Kumbotso local government areas that have a very high risk of malaria attacks. There is also the need to research more on the relationship between malaria prevalence and some key socio-anthropogenic factors such as literacy level, income level, HIV status, pregnancy status and meteorological factors.

Role of IAS 41 “Agriculture” on Establishment of Innovation Systems

Financial reporting has known as an important information bases for decision makers. It has role on national economic growth, institutional and educational developments, to link to global and other regional systems. This study reviews and discusses theoretical perspectives of accounting around the globe in order to find financial reporting that can be useful information bases. To do so, I surrounded our studies into two approaches: financial reporting general role for economic growth, and report’s consequences to institutional, educational developments. In these regards, I found a significant distinguishing between national financial reporting and international approaches. After that, I focused the study in deep inside of accounting and found the unique accounting opportunities that can be applied to establish innovation system.  

Heavy metal contamination in some soils of the McMurdo Sound region, Antarctica

Soil samples from eight sites at Marble Point and Pram Point, McMurdo Sound region, contaminated by human activities were examined for heavy metal content, using sequential extraction methods. The redistribution of lead, zinc and copper arising from point sources of these metals was demonstrated. The levels found are not considered to represent serious pollution but do indicate that human activities can change the chemistry of the Antarctic environment in localized areas

Expression of Green Fluorescence Protein (GFP) in Zebrafish Muscle through Injection: A Gene Therapy Model

Expression of the target gene is important for gene therapy. Presently, localized transgenesis is used for gene therapy which can be achieved by a target gene expression. Here, we have reported the plasmid mediated gene therapy to zebrafish model. For this purpose, we have chosen green fluorescent protein (GFP) as a target gene because the expression can be detected easily. GFP was inserted in a plasmid vector, pQE30 to develop the vector pQE30GFP. The plasmid pQE30GFP was constructed form plasmid, pQE30 and pEGFPC2. pQE30GFP injected directly in one group of fish into the muscle where luciferase expression was noted. In another group, after injection electroporation was performed where we have also noted luciferase expression; but, electroporation cause muscle injury to the zebrafish. In our case, the expression was very strong at the site of injection in first group in compare to electroporation group and in both the cases expression was stable more than two weeks

Photoluminescence of near-lattice-matched GaN/AlInN quantum wells grown on free-standing GaN and on sapphire substrates

Near-lattice-matched GaN/Al1−xInxN single quantum wells, grown using both free-standing GaN and conventional GaN-on-sapphire substrates, are studied by photoluminescence (PL) and PL excitation spectroscopies. PL spectra distinguish luminescence originating in the wells, barriers, and underlying GaN buffer layers. The spectra also reveal significant differences between structures grown simultaneously on the different substrates. The quantum well transition energy decreases as the well width increases due to the intense in-built electric fields, estimated to be 3.0±0.5 MeV/cm, that persist in strain free GaN/Al1−xInxN. Screening of these fields is studied using the excitation power dependence of the P

Estimating Aboveground Biomass Using Allometric Models And Adaptive Learning Rate Optimization Algorithms

Forest aboveground biomass (AGB) is imperative in the study of climate change and the carbon cycle in the global terrestrial ecosystem. Developing a credible approach to estimate forest biomass and carbon stocks is essential. Four allometric models were used with two optimization algorithms; Modified Root Mean Square Propagation (Modified RMSProp) and Modified Adaptive Moment Estimation (Modified Adam) were also used to train each model. Convergence was achieved after 1000 iterations of Modified RMSProp and 200 iterations of Modified Adam for all the models. A learning rate of 0.01 and exponential decay rates of 0.9 and 0.999 for the first and second momentum. A loss function of 0.5 Mean Square Error (0.5 MSE) was used and Root Mean Square Error (RMSE) was used to judge the accuracy of the models. The study showed that the optimization algorithms were both able to accurately optimize three of the four allometric models. While Modified Adam was the more efficient optimizer, it had the highest RMSE value 2.3910 and Modified RMSProp had the least RMSE value 0.37381. However, there was no statistically significant difference between the accuracy of the models optimized by both algorithms

SOLUTION OF A COMPLEX OF PROBLEMS OF OPERATIONAL PLANNING AND MANAGEMENT IN THE CONDITIONS OF A MINING LANDMARK IN AZERBAIJAN

The main direction of the economic and social development of the Republic of Azerbaijan is the intensification of agricultural production. Irrigation is a powerful means of intensifying agricultural production in the context of its specialization. In areas with insufficient moisture (especially typical for mountainous areas), irrigation is one of the decisive factors in growing high and stable crop yields.This requires the development of new technical solutions and the introduction of automated systems for low-intensity irrigation of agricultural crops that meet the requirements of ecology and environmental protection of their habitat, which makes it possible to improve the ecological state of irrigated lands and reduce water consumption. per unit of production and increasing the yield of individual crops in irrigated fields
