Abstract

Sunflower oil is known for its therapeutic properties and culinary use. It is an important alimentary source of tocopherol and unsaturated fatty acids, and is used especially for wound healing. Studies indicate that it also has antimicrobial potential. The ozonation of oils of vegetable sources has been explored as a way to enhance their therapeutic properties; however, studies that provide evidence of such benefits are still lacking. In the field of veterinary medicine, such data are even more scarce. In this study, the antimicrobial activity of ozonated sunflower oil was compared to that of non-ozonated oil, in an in vitro system. We used clinical isolates of Escherichia coli, obtained from intrauterine lavages of mares with endometritis. Tests were conducted using the minimum inhibitory concentration method. Our data open doors for discussion on the use of sunflower oil, with or without ozone treatment, for therapeutic purposes in veterinary medicine.

Abstract

Spatial inequality of development is an important issue in Bangladesh. In this study a set of sectors-education, infrastructure, health, and economy-and sectoral components/indicators were selected aiming at investigating the spatial inequality scenario of Bangladesh. All components/indicators of each sector were weighted overlaid using ArcGIS tool. Finally, the overall spatial inequality of development was generated overlaying all the sectoral inequality maps. The spatial inequalities were revealed categorically from the highest overlaid cell value as the most lagged area to the lowest value as the most advance area. A serious centralized character towards the capital Dhaka was identified almost in all the sectors in spatial inequality maps of Bangladesh. The overall spatial inequality map identified a total of 16 districts in the comparatively ‘lagged area’ category; and 44 districts in the category of the ‘moderate area’. Only one district (the capital Dhaka) was identified in the category of ‘most advance area’, while three districts (Chittagong, Gazipur, Narayanganj) found in the ‘advance area’ category. Most of the lagged districts were identified in the north-west and north-east parts of Bangladesh. Besides, the districts of Chittagong Hill Tracts (Bandarban, Khagrachari, Rangamati) were also found most lagged..

Abstract

This paper reports a comparison of different types of springs used in MEMS based capacitive accelerometers. In this work MEMS based Single-axis accelerometers are designed using different Suspension systems. Analysis of the structure is done for resonant frequency of 2kHz. Analytical modeling of the different suspensions is presented for the specified frequency. Stress, displacement and capacitive analysis of the accelerometer is done. The sensitivity of the accelerometer with parallel beam  suspension is 70nm/g, 50nm/g for folded beam suspension and 35nm/g for serpentine beam suspension. Hence parallel beam suspension has 0.7 times improved sensitivity than folded beam and 2 times better than serpentine suspension accelerometer. Whereas the stress obtained for folded beam is better than the other two. Hence  Parallel beam suspension is preferred for higher sensitivity and accuracy whereas Folded beam suspension is preferred for greater structural stability By comparing these devices, it is concluded that a compromise on certain parameters is required in order meet the requirements. If there is higher displacement sensitivity then there is lower mechanical stability and vice versa. The simulations are carried out using COMSOL Multiphysics.

Abstract

Pure thiourea barium chloride (TBC) crystals were grown by slow evaporation from aqueous solution and slow cooling (0.1oC/ day). The growth was carried out for 21 days by keeping the bath at a temperature of 39oC.   Optimal molecular structures are explored by DFT / B3LYP method with 6-31G (d, p) based synthesis. Hyper conjugative interactions, charge delocalization and intra molecular hydrogen bonding have been analyzed using natural bond orbital (NBO) analysis. Moreover lower in the HOMO and LUMO energy gap explains the eventual charge transfer interactions taking place within the molecule, which influences the biological activity of the compound and also energy serves as a measure of the excitability of a compound, the smaller the energy gap, the more easily the compound will be excited.  Electronic structures were discussed and the displacement of the electron density was determined. Second – order perturbation theory analysis of the intra molecular bonds of Methyl Orange doped TBC were derived.

Abstract

Caffeine is a naturally occurring chemical stimulant found in leaves, seeds and fruits of numerous plant species of groups of nitrogenous organic compound of the alkaloid group called trimethylxanthine. Energy drinks are non-alcoholic beverage that contain high level of substances capable of exciting any bodily functions and tends to stimulate the brain and the central nervous system. The aim and objective of the research is to determine the caffeine content and concentration of caffeine of five (5) different beverages (energy drink) sold in Ekwulobia in Aguata local Government Area. The caffeine content in the drink by name predator, fearless, bullet, climax and power horse were determined. The result showed the level of caffeine in the respective energy drink brand as 0.721mg/L for predator (PRE 101), 0.545mg/L for fearless ( FEA 102), 0.275 mg/L for bullet (BUL 103), 0.305 mg/L for climax (CLI 104) and 1.135 mg/L power horse (POW 105). The result showed that the caffeine content in the energy drink samples were significantly lower than the authorized level of (32mg/100L) recommended by World Health Organization which means that the energy drink analyzed are safe for consumption. .

Abstract

The recent rise in fire incidents in Anambra State has resulted in displacement, stress, psychological, adverse effect on the lives of its inhabitants and a devastating consequence on the economy.  The objectives of the study include examining the estimated value of properties loss due to fire outbreak within the study period and to employ the Random Forest regression model to predict the estimated losses associated with fire disasters in Anambra State. The data for the study was a secondary data obtained from the records Department of the Anambra State Fire Service, Headquarters Awka. The study used the Random Forest regression method to analyze the data obtained in this study. The Random Forest regression analysis was employed to predict the estimated value of properties loss (EVPL) due to fire outbreak. The explanatory variables used for the prediction of the response variable were Number of victims (NV), Percentage of Plain Land (PL), Population Size (PS), Population Density (PD) and Actual Revenue by LGA (ARLGA). The findings of the study revealed that EVPL has a higher Skewness and Kurtosis followed by NV and the least was found to be PL. Further result revealed that the percentage of variance explained was 12.03%, sum of square error (SSE) was 31.41, root mean square error (RMSE) was 0.7236 while the R-square was 59.18%. This result implies that the model was moderately positively adequate since it recorded a positive coefficient of determination. The findings from the variable importance analysis showed that Population Density played a major role in the estimation of the response variable followed by the number of victims while population size was found to be the least important variable for estimating the response variable.
