News Reporting of Injury Prevalence in Football: A Study of Selected Nigerian Online Newspapers

Despite the importance of football as an effective means of developing physical activity and fitness, routine data of football-related injuries are either inadequate or underreported, particularly in Nigeria. To develop an understanding of the football-related injuries and determine the prospects for prevention, logical and useful information specifying the occurrence of these incidents is necessary. Using a content analysis of 94 football-related news articles, this study identified the most commonly reported football-related injuries in Nigerian newspapers and determined their extent of coverage from agenda-setting perspectives. Altogether, five national newspapers with the highest readership and online popularity were selected using purposive sampling. Only football-related news articles were collected from the respective websites of the newspapers using internet-based searches between January 2015 and September 2019.The findings showed that knee, ankle, and hamstring are the most commonly affected locations in football-related injuries according to the news reports.This study shows that media-based analysis of football-related injuries could supplement other methods, such as prospective and retrospective analyses, particularly in the Nigerian context

Determinant of Islamic banking institutions' profitability in Malaysia

Starting with the establishment of the Malaysia’s first Islamic bank namely Bank Islam Malaysia Berhad (BIMB) in 1983, the Islamic banking system has shown better development and is now widely accepted by Muslims as well as non-Muslim in this country. Islamic Banking System which follows the rule of Shariah plays a vital role in Malaysia as its profitability contributes to the growth of the economy. Therefore, this study was conducted in order to examine the determinants of profitability for Islamic Banking Institutions in Malaysia which are listed on the Bursa Malaysia. The bank-specific determinants (internal factors) include capital adequacy, credit risk, liquidity, bank size and management of expenses. The methodology employed is the Generalized Least Square (GLS) panel data analysis, using quarterly data from nine Islamic banks, which consist of foreign and local Islamic banks incorporated in Malaysia for the period 2007-2009. The result revealed that only the bank size is significant in determining the profitability with positive relationship. It is to be concluded then that, even though there is a lot of determining factors, only the bank’s size may put confidence in the eyes of the consumers. For the future studies, it is recommended to have a wider scope where other Malaysian Islamic financial institutions and more determinant factors can be taken into account

The final products for the design have been fabricated successfully

Lipid lowering effect of antioxidant alpha-lipoic acid in experimental atherosclerosis.

Accumulating data demonstrated that hypercholesterolemia and oxidative stress play an important role in the development of atherosclerosis. In the present study, a protective activity of alpha-lipoic acid; a metabolic antioxidant in hypercholesterolemic-induced animals was investigated. Eighteen adult male New Zealand White (NZW) rabbit were segregated into three groups labelled as group N, HCD and ALA (n = 6). Group N (normal control) was fed with normal chow, the rest (HCD and ALA) were fed with 100 g/head/day of 1% cholesterol rich diet to induce hypercholesterolemia. Four point two mg/body weight of alpha lipoic acid was concomintantly supplemented to the ALA group. Drinking water was given ad-libitum. The study was designed for 10 weeks. Blood sampling was taken from the ear lobe vein at the beginning, week 5 and week 10. Plasma was prepared for lipid profile estimation and microsomal lipid peroxidation index indicated with malondialdehyde (MDA) formation. At the end of the experiment, the animals were sacrificed and the aorta were excised for intimal lesion analysis. The plasma total cholesterol (TC) and low density lipoprotein (LDL) levels were found to be significantly low in ALA group compared to that of the HCD group (P<0.05). Similarly, low level of MDA (p<0.05) in ALA group was observed compared to that of the HCD group showing a significant reduction of lipid peroxidation activity. Histomorphometric intimal lesion analysis of the aorta showing less of atheromatous plaque formation in alpha lipoic acid supplemented group (p<0.05) compared to HCD group. These findings suggested that alpha lipoic acid posses a dual lipid lowering and anti-atherosclerotic properties indicated with low plasma TC and LDL levels and reduction of athero-lesion formation in hypercholesterolemic-induced rabbits

The Effect Of WEDM Cutting Parameter On Inconel 718 Subsurface Microhardness

This paper reports on the effect of wire electrical discharge machine (WEDM) cutting parameter on the subsurface hardness of Inconel 718. The response surface methodology (RSM)using Box-Behnken design was used to conduct the experiment and analyze the relationship between control variables and responses. A total of 8 runs was carried out during the experiment. The Historical Data of Response Surface Methodology (RSM) was used as a tool of design of experiment (DOE). The selected WEDM parameters were Voltage (40-42V), feed rate (6-8V) and current (0.5-1.5 mm/min). The subsurface hardness was measured at the distance of 50 μm, 100 μm, 300 μm, 500 μm beneath the cutting surface. Observation of the results shows that the subsurface hardness is higher at the distance of 50μm than 500 um. The hardness was gradually decreased toward bulk hardness of HV0.1 270. Analysis of variance (ANOVA) was used to identify the significant effect of the factors on the response. Based on the analysis, feed rate and current were found to be the most significant factors in hardness change. Mathematical models were developed for hardness prediction with an average error of 2.7%. The minimum hardness change of HV0.1 30 was obtained by the combination of feed rate = 1.29 mm/min, servo voltage = 40.33 V,current = 7.94 A

A Review On Oil-Based Nanofluid As Next-Generation Insulation For Transformer Application

Due to the increasing demand on developing good insulation, several researchers have performed experimental studies to prove the effectiveness and capabilities of transformer oil. This is done by suspending nanosized solid particles in the oil (nanofluid) for transformer applications. In brief, this paper presents a compilation of research studies which is divided into three parts. Part I discuss the preparation of the nanofluid which involves different types of nanomaterials, the optimal amount of concentrations, and applicable synthesisation methods for producing stably suspended nanofluids. In Part II, the nanofluid’s performances including the electrical breakdown voltages, impulse tests, and thermal and dielectric behaviour are reviewed in depth and compared. Part III emphasizes the limitation of nanofluids. Most researchers have agreed that appropriate concentrations of nanomaterials and the preparation method for nanofluids mainly affect the performance of nanofluids especially in terms of electrical properties. Meanwhile, types of nanomaterials and base oil also play a vital role in producing nanofluids as a better alternative transformer oil. However, among a few researchers, there are concerns regarding the issue of agglomeration and inconsistencies of findings that need to be resolved. Therefore, a few aspects must be taken into consideration to produce the next generation of high heat dissipation insulation

Magnetism And Thermomechanical Properties In Si Substituted MnCoGe Compounds

MnCoGe-based compounds have been increasingly studied due to their possible large magnetocaloric effect correlated to the magnetostructural coupling. In this research, a comprehensive study of structure, magnetic phase transition, magnetocaloric effect and thermomechanical properties for MnCoGe1−xSix is reported. Room temperature X-ray diffraction indicates that the MnCoGe1−xSix (x = 0, 0.05, 0.1, 0.15 and 0.2) alloys have a major phase consisting of an orthorhombic TiNiSi-type structure with increasing lattice parameter b and decreasing others (a and c) with increasing Si concentration. Along with M-T and DSC measurements, it is indicated that the Tc value increased with higher Si concentration and decreased for structural transition temperature Tstr. The temperature dependence of the magnetization curves overlaps completely, indicating that there is no thermal hysteresis, and it is shown that the transition is the second-order type. It is also shown that the decreased magnetization on the replacement of Si for Ge decreases the value of −ΔSM from −ΔSM~8.36 J kg−1 K−1 at x = 0 to −ΔSM~5.49 J kg−1 K−1 at x = 0.2 with 5 T applied field. The performed Landau theory has confirmed the second-order transition in this study, which is consistent with the Banerjee criterion. The magnetic measurement and thermomechanical properties revealed the structural transition that takes place with Si substitution of G
