Gabbronorite from Jijal Complex, Kamila Amphibolite Belt and Chilas Complex, Northern Pakistan: Implications for Arc Genesis
Authors: Rehman Saffi Ur , Arif Muhammad
Published: December 2020

Rocks of gabbronoritic composition occur in three principal tectono-stratigraphic units forming the lower andmiddle parts of the Kohistan Island arc (KIA). These include the Jijal complex (JC), the Kamila Amphibolite belt (KAB)and the Chilas complex (CHC). The Jijal complex constitutes the lowermost part and hence is regarded as the root zoneof KIA. Its north-eastern part adjacent to KAB contains gabbronorite as a minor component in the form of small irregularpatches and layers within garnet granulite. The JC gabbronorite is sub-equigranular, medium to coarse grained, largelymassive and consists of variable amounts of plagioclase (53-71 %), orthopyroxene (14-27 %) and clinopyroxene (11-19%) as essential constituents and accessory to minor amounts of amphibole (1-9 %), opaque ore (1-6 %) and orthoclase(1-4 %). The occurrence and distribution of biotite, epidote, chlorite, clay, sericite, muscovite, quartz and actinolite inthe studied samples suggest their formation through alteration and/ or reaction between pre-existing minerals. In manycases, these minerals are disposed such that a variety of simple and complex corona structures are produced. The principalpetrographic features (modal composition, optical properties of the major mineral phases, exsolution in pyroxenes,products of alteration and reactions and the resulting corona textures) of the JC gabbronorite are broadly similar togabbronorites from both the KAB and CHC. Although the observed similarities could reflect identical physico-chemicalconditions during subsolidus or metamorphic re-equilibration, the possibility of a genetic relationship amonggabbronorites from all the three tectono-magmatic units of the KIA (i.e. the JC, KAB and CHC) cannot be ruled out.

The analysis of the breeds given on natural gas content, studying of the nature usual and the souffle of gas-allocations, emergence and courses of the gas-dynamical phenomena allow to optimize technologies of mining and to ensure safety of work.
Analysis Of The Influence Of Corporate Size, Leverage , Price Earning Ratio (PER) And Return On Equity (ROE) On Company Value
Authors: Prasetya Tegar , Riyanto Setyo
Published: December 2020

This study aimed to n use values the company can be determined by many factors, among which the size of the company, leverage, the price earnings ratio (PER) and Return On Equity (ROE) Firm size is considered able to influence the value of the company . the large size of the company shows that the company is developing so that investors will respond positively and the value of the company will increase. The relative market share shows the company's competitiveness is higher than its main competitors. Investors will respond positively so that the value of the company will increase.

Companies that have total assets with large amounts or commonly referred to as large companies will get more attention from investors, creditors and other users of financial information compared to small companies. If the company has a large total assets, the management will be more flexible in using existing assets in the company. This ease in controlling assets will increase the value of the company. In the face of economic turmoil, usually a more sturdy company stands are large, although it does not rule out bankruptcy, so investors tend to like large-sized companies rather than small-sized companies.

A Case Study Series of the Health Status and Key Anthropometry in Very Large Strength Athletes
Authors: Chappell Andrew , Simper Trevor
Published: December 2020

Strongmen are characterised by large mass they use to perform feats of strength, the effect this large mass has on the athlete’s health are unknown. The aim of this study was to: characterise a group of strongmen and to compare observed values with established parameters for good health. We measured: resting metabolic rate, body composition, skinfolds, lipid profiles, fasted glucose, blood pressure, power output, and grip strength in 6 competitive strongmen over 6 months. Blood pressure varied with 3 of the strongmen recording hypertensive values. Fasted blood glucose levels aligned with values for healthy adults, cholesterol/lipid profiles variable with the suggestion that values are generally poorer in strongmen than in healthy adults. The large body mass of the strongmen corresponded with a large amount of adipose tissue, which may incur risk for non-communicable disease. Furthermore, the risk of disease may be further compounded by anabolic steroid use. Dietary considerations are made for protecting cardiovascular health and the potential for 'healthy' weight gain. To our knowledge this is the first such nested cohort study in the area of strongmen competitors.  Larger studies are needed to confirm and further elucidate this data. Considerations for protecting the health of strongman competition is made.

Published: December 2020

Disease transmission among health workers is associated with overcrowding, absence of isolation facilities, and environmental contamination. Knowledge of disease will influence the attitude and practice of medical staff. Wrong attitudes and practices directly increase the risk of infection. This study aims to analyze the influence of Knowledge, Attitude, Practice (KAP) nurses who handle the COVID-19 pandemic in the Emergency Room of the General Hospital Center (RSUP) Dr. Wahidin Sudirohusodo. This research is a quantitative research. The design used was analytic observational with a cross-sectional study approach. A sample of 83 nurses was selected using purposive sampling technique with the criteria of nurses on duty in the hospital. Data were analyzed using the Logistic Regression test. The results of multivariate analysis obtained p-value below 0.05 (p <0.05), meaning that the attitude and practice variables had an influence on the dependent variable (job stress). For the most dominant variable that affects work stress, it can be seen from the largest OR value, namely practice with OR = 4.484. The high OR value obtained means that practice is the most dominant variable affecting the dependent variable, namely work stress. The hospital management identifies the behavior of each employee in an effort to adjust their needs, provides training programs to maintain and protect themselves while working, and the incentives obtained. So that employees can work calmly and be confident in their work. It is suggested for further research to be able to use other research designs, so that we can find out factors other than KAP that can affect work stress, either directly or indirectly.

Authors: S. Francisco April Rose
Published: December 2020

This study aimed at investigating the effects of teachers’ personal and professional demographic characteristics on students’ academic performance in English. To achieve this aim, the researcher used a sample of 37 English secondary teachers and 400 students in the District of Plaridel, Schools Division Office of Bulacan during the academic year 2018-2019. The researcher used the descriptive-correlational method of research, which used a researcher-made questionnaire as the primary data gathering technique. The results of the regression analysis show that the eight (8) variables of the personal demographic characteristics and the four (4) variables of the professional demographic characteristics affect students’ academic performance in English to a various extent as shown by the non-zero coefficients. Results of the analysis of variance of the regression of personal and professional demographic characteristics on students’ academic performance revealed an Fvalue of .955 with a p-value of .490 and an F-value of 1.197 with a p-value of .331. Since the associated probability of the F-value is higher than alpha (0.05), the null hypothesis has to be sustained. This means that all variables of the personal and professional demographic characteristics do not exert significant effects on students’ academic performance in English. Conclusions were drawn and recommendations were offered.

Authors: Pushpakumara H.M.C. , Jayaweera Prasad M. , M.K. Wanniarachchige
Published: December 2020

Recently, quality assurance has attracted widespread attention in higher education institutes in developing countries. Such initiatives mainly focus on standardising higher education while improving the relevance of degree programs. Nevertheless, current quality assurance mechanisms, particularly in developing countries, heavily rely on a document based manual review process. Given the drawbacks associated with such processes, the necessity of technology-based solutions is being recognised. Even though information system applications are widely used nowadays by the universities to increase the efficiency, quality improvement aspects have not been given due focus. TOGAF is a widely accepted cyclic approach for developing enterprise architecture. This study demonstrates how a TOGAF based business architecture can be used to analyse and improve the existing teaching-learning process in higher education as an integral part of quality assurance.

Published: December 2020

The social vices rape “has been around” for a very long time, it is as old as humankind. It has been experiencing in almost all the countries of the world. However, in a country like Nigeria, the issue of rape among the people had been on the rising rate these days as many babies, aged and teenagers had been raped to death. It is in view of the above challenges that this paper examined the causes, impact and solutions to the rising cases of rape in Nigeria. The paper adopted the relative deprivation theory to validate its arguments, while data are gathered through the secondary methods as data are retrieved from books, articles, newspapers and internet materials. This paper argued that the major causes of the rising cases of rape in Nigeria are youth’s unemployment that is realized as a result of bad governance, and submit that good governance is the only lasting and perpetual solution to the rising cases of rape in Nigeria.

Published: December 2020

Long term diabetes mellitus (DM) is associated with serious complications such as nephropathy. Previous studies revealed the ability of A. excelsa leaf extract treatment to reduce fasting blood glucose (FBG) in streptozotocin (STZ)-induced diabetic rats. The aim of this study was to determine the effect of A. excelsa extract in delaying the progression of diabetic nephropathy by evaluating the kidney structure and function. The effects were compared with 2 positive controls, which were metformin (standard drug) and quercetin (plant active compound). Induction of diabetic conditions was conducted by the intraperitoneal (IP) injection of STZ (60 mg/kg bwt) in male Sprague Dawley rats. The experimental animals were grouped into: 1) normal control (NC, saline); 2) diabetic control (DC, saline); 3) metformin-treated diabetic rats (DMET, 1000 mg/kg bwt); 4) quercetin-treated diabetic rats (DQ, 40 mg/kg bwt), and 5) A. excelsa-treated diabetic rats (DAE, 250 mg/kg bwt). All treatments were given once daily for 8 weeks through oral gavage. The inter-relation between the changes in the fasting blood glucose and kidney oxidative stress, structure, and function was evaluated. The results showed a significant increase (p < 0.05) of MDA and SOD level and a decrease (p < 0.05) of GPx levels, plus distortion of renal morphology among the DC and DMET groups. Meanwhile, both DQ and DAE groups showed significant reduction (p < 0.05) of MDA levels and elevation (p < 0.05) of SOD and GPx levels. The quercetin and A. excelsa treatments also improved the kidney function parameters and morphological changes of the diabetic rats. These findings indicate that quercetin and A. excelsa possess renal therapeutic effects.
Computación interactiva y emergente en colonias de hormigas
Authors: Gómez-Cruz Nelson Alfonso
Published: December 2020

Los sistemas vivos procesan información; esto es lo que hacen para vivir. La capacidad de procesar información es, de hecho, uno de los rasgos más sobresalientes de los sistemas complejos adaptativos en general. Se suele aceptar, desde la biología y las ciencias de la computación, que el modelo estándar de computación algorítmica, representado por la máquina de Turing, establece los límites teóricos de lo que la vida puede computar y lo que no. Pese a ello, el tipo de computaciones que realizan los sistemas vivos difiere en maneras fundamentales de las soportadas por la máquina de Turing. En este artículo se demuestra que el sistema de navegación que emplean individualmente las hormigas y las estrategias colectivas para la recolección óptima de alimentos que usa la colonia no se pueden reducir a formas de computación algorítmica. Esta idea justifica la necesidad de desarrollar nuevos modelos de computación que nos permitan desentrañar la lógica computacional y la complejidad de la vida.

Published: December 2020

La pielonefritis enfisematosa es una emergencia urológica caracterizada por una infección parenquimatosa y perinéfrica, aguda necrosante, causada por uropatógenos formadores de gas. Es considerada una entidad poco común, teniendo una mayor incidencia en países en vías de desarrollo. Si bien, la patogenia no está bien comprendida existen varios factores bien identificados que se encuentran envueltos en un espectro de elementos que tienen por resultado la producción de gas en el parénquima renal. Varios factores de mal pronóstico asociados a una alta mortalidad han sido identificados en diferentes cohortes. Típicamente podemos dividir el tratamiento de estos pacientes en manejo médico, manejo médico y drenaje endoscópico o percutáneo y nefrectomía de urgencia.; sin embargo, al existir muy pocas guías clínicas o algoritmos de tratamiento, no hay un consenso en el manejo que deben tener estos pacientes.

Objetivo: Determinar la incontinencia urinaria (iu) en mujeres con obesidad y el efecto 3, 6 y 12 meses después de la cirugía bariátrica.

Materiales y Métodos: Entre abril y julio de 2017 se realizó un estudio observacional, prospectivo y longitudinal en mujeres con obesidad, sometidas a cirugía bariátrica, realizando análisis estadístico inferencial y bivariado mediante Chi Cuadrada.

Resultados : Sesenta y siete pacientes en total, de las cuales 73.1% tenían algún tipo de iu. Edad de 42.7 años, peso prequirúrgico 108.3 kg e imc de 42.7kg/m2. La incontinencia más frecuente fue de esfuerzo (55.1%), la iu leve apareció en el 65.3% y la afección en la calidad de vida en el 30.6%. Un año después, el imc fue de 30.9 Kg/m2, con una persistencia de iu del 13.4%, todas de esfuerzo. La mejoría postquirúrgica de iu fue estadísticamente significativa para los tres tipos (p=0.001), frecuencia (p<0.001) y en la calidad de vida (p<0.001), obteniendo una resolución completa de 81.6%.

Conclusiones: Confirmamos que la pérdida de peso posterior a la cirugía bariátrica tiene una gran resolución de la iu, debiendo considerarse como una terapia de primera línea. Aunque los objetivos principales de esta cirugía son disminuir las morbilidades cardiovasculares, la recuperación y/o mejoría de la iu debería ser evaluada rutinariamente, ofreciendo otro beneficio a largo plazo.
Effects of Valproic Acid on Selected Kidney Function Indices in Rats
Authors: Igunnu A. , Owolabi O. O. , Bankole I. O.
Published: December 2020

Valproic acid (VPA) has been demonstrated to exhibit anti-diabetic effect and attenuate hypertensive responses
in animal models but its safety evaluation on the kidney has not been reported. This study investigated the effect
of VPA on selected kidney function indices of rats. Twenty healthy Wistar rats were randomly grouped into 4
of 5 rats each. Rats in group 1 (control) were administered clean water only, while rats in groups 2, 3 and 4 were
administered 100, 300 and 600 mg/kg body weight (bw) of VPA, respectively for 3 weeks. Serum concentrations
of creatinine, urea, sodium, potassium, phosphate and chloride ions as well as the activities of alkaline
phosphatase (ALP), acid phosphatase (ACP), aspartate aminotransferase (AST), and alanine aminotransferase
(ALT) in the kidney and serum of rats were determined. VPA at the 3 doses administered did not significantly
affect (p>0.05) the kidney/body weight ratio, serum concentrations of creatinine, urea, sodium ion and phosphate
ion when compared with control. VPA at 600 mg/kg bw alone and at both 300 and 600 mg/kg bw significantly
increased (p<0.05) the serum levels of potassium and chloride ions, respectively. VPA did not significantly affect
(p>0.05) the kidney ALP and ALT activities as well as the serum ALP, ACP, AST and ALT activities but
significantly increased (p<0.05) the kidney ACP and AST activities at 300 mg/kg bw. These results imply that
treatment with VPA at higher doses may adversely affect the reabsorption of chloride ion in the kidney which
may alter the acid/base balance and impair nerve impulse transmission.

Hypercholesterolemia is a chief risk reason for atherosclerosis. Triton-WR 1339 (Tyloxapol) was used by several investigators to initiate hypercholesterolemia in animals. Housefly maggots contain high larval protein extract (PE) that is used as an anti-atherosclerosis. The goal of the current study was to evaluate the possible protective effects of the PE of houseflies against Triton-WR 1339-induced hyperlipidemia, oxidative damage, and histopathological changes of the liver and dorsal aorta of male mice. In this study, four groups of experimental mice, including ten mice each, were classified into: Group I, mice were administered with 0.5 ml saline solution, and considered as a positive control; Group II, mice were administered day after day by gavage with 0.5 ml of 200 mg/kg bw PE; Group III, hyperlipidemic mice were taken no treatment till the end of experiment and Group IV, the hyperlipidemic mice were administered day after day by gavage with 200 mg/kg bw PE. On day 40, the mice were anesthetized, blood samples were collected, the livers and the aorta were dissected for various biochemical tests and histopathological examinations. The biochemical parameters, triglycerides (TGs), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C) and lipid peroxidation (LPO) were increased, and reduction in high-density lipoprotein-cholesterol (HDL-C), the total glutathione (GSH) and the glutathione peroxidase (GPx) levels were observed following Triton WR-1339 treatment in mice. After administration of the PE (200 mg/kg bw), the results revealed significant reduction in serum TC and TGs while HDL-C, oxidative stress levels in liver tissue, LPO, GSH and GPx were significantly increased. Histopathological examinations of the liver tissue and the aorta of mice showed alterations afterwards Triton WR-1339 administration. Treatment with 200 mg/kg bw PE showed beneficial effects with lower capsular thickening, enlargment of hepatocytes and much lower inflammatory cell infiltration.

The use of media in providing counseling services greatly affects the skills of counselors in conducting counseling through virtual internet media. The development of communication technology in the era of 4.0 makes counselors more familiar with, utilizing and applying counseling media virtually via the internet. The development of communication technology requires counselors to innovate, especially in providing e-counseling services as a forum for counselors to provide alternative solutions to problems faced by counselees. This research method is descriptive qualitative research, the source of this research data comes from document studies in the form of books and previous research which is used as a source of data that supports research. The results of this study indicate that online counseling is in the form of virtual counseling technology media, namely: websites, telephones or cellphones, email, video conferencing, chat, instant messaging, computers and other social media networks. The ethics that must be considered by online counselors are how to establish good relationships via the internet, confidentiality aspects in the implementation of counseling, legal aspects in telecommunications via the internet and licensing. Thus online counselors are required to work professionally by paying attention to ethics in the implementation of online counseling.

Abstract. The outflow of the East Asian haze (EAH) has attracted much attention in recent years. For downstream areas, it is meaningful to understand the impact of crucial upstream sources and the process analysis during transport. This study evaluated the impact of PM2.5 from the three largest industrial regions on the Asian continent, namely the Bohai Rim industrial region (BRIR), Yangtze River Delta industrial region (YRDIR), and
Pearl River Delta industrial region (PRDIR), in Taiwan and discussed the
processes during transport with the help of air quality modeling. The
simulation results revealed that the contributions of monthly average PM2.5 from BRIR and YRDIR were 0.7–1.1 and 1.2–1.9 µg m−3 (∼ 5 % and 7.5 %
of the total concentration) in Taiwan, respectively, in January 2017. When
the Asian anticyclone moved from the Asian continent to the western Pacific, e.g., on 9 January 2017, the contributions from BRIR and YRDIR to northern Taiwan could reach daily averages of 8 and 11 µg m−3. The transport of EAH from BRIR and YRDIR to low-latitude regions was horizontal advection (HADV), vertical advection (ZADV), and vertical diffusion (VDIF) over the Bohai Sea and East China Sea. Over the Taiwan Strait and the northern South China Sea, cloud processes (CLDS) were the major contribution to PM2.5 due to a high relative humidity environment. Along the transport from high-latitude regions to low-latitude regions, aerosol chemistry (AERO)
and dry deposition (DDEP) were the major removal processes. When the EAH
intruded into northern Taiwan, the major processes for the gains of
PM2.5 in northern Taiwan were HADV and AERO. The stronger the EAH, the
more the EAH could influence central and southern Taiwan. Although PRDIR is located downstream of Taiwan under northeasterly wind, the PM2.5 from PRDIR could be lifted upward above the boundary layer, allowing it to move
eastwards. When the PM2.5 plume moved over Taiwan and was blocked by
mountains, PM2.5 could be transported downward, via boundary layer mixing (VDIF), as it was further enhanced by the passing cold surge. In contrast, for the simulation of July 2017, the influence from the three industrial regions was almost negligible unless there was a special weather system, such as thermal lows which may have carried pollutants from PRDIR to Taiwan, but this occurrence was rare.
Comment on Identification of the IMF sector structure in near-real time by ground magnetic data by Janzhura and Troshichev (2011)

Abstract. The only published description of the solar wind sector (SS) term used for the reference level in the post-event and real-time derivation of the Polar Cap (PC) indices, PCN (North) and PCS (South), in the version endorsed by the International Association for Geomagnetism and Aeronomy (IAGA) is found in the commented publication, Janzhura and Troshichev (2011): Identification of the IMF sector structure in near-real time by ground magnetic data, Annales Geophysicae, 29, 1491–1500. Actually, the publication has served as basis for the index endorsement by IAGA in 2013. However, neither the illustrations nor the results presented there have been derived by the specified near-real time method. Figs. 1, 6, 7, and 8 display values derived by post-event calculations based on daily medians smoothed over 7 days centred on the day of interest. Figs. 2, 3, and 4 display observed values smoothed over 7 days, while the remaining Fig. 5 displays averages over 4 months. In summary, there are strong disagreements between indications in the title, abstract, and statements in the text compared to the actual results and their illustrations.
