Authors: Mahlangu Phumzile T. , K. Nzaumvila Doudou , Ramochele-Ngwenya Maselake M. M. , H. Mabuza Langalibalele 
Published: September 2021

Background:
Sexually Transmitted Infections (STIs) are a public health concern worldwide. Awareness campaigns have been conducted worldwide, educating communities on their manifestations, prevention, and steps to be taken once infected.

Objective:
This study aimed to determine childbearing women’s knowledge, attitudes, and beliefs about STIs.

Methods:
A cross-sectional study was conducted at a district hospital near Pretoria in South Africa. The population comprised 190 childbearing women registered at the family planning clinic of the hospital. The sample size of 130 participants was computed at a confidence level of 95% with an error margin of 5%. Participants were selected using a table of random numbers, and data collection by means of a researcher-administered questionnaire. The SPSS software (version 22) was used for data analysis. Statistical significance was set at p < 0.05.

Results:
Of the 130 participants, 123(94.6%) knew that STIs can be acquired through sex, and 41(31.5%) did not know that STIs can be asymptomatic. The most known STI was HIV by 117(90%) participants, the most known transmission route was sexual intercourse by 126 (96.9%) participants, and the most known symptom was penile/vaginal discharge by 108(83%) participants. Seventy-four (57.3%) regarded STIs as not dangerous, based on their belief that STIs are curable. There was generally a poor association between knowledge on STIs and alcohol consumption (p > 0.05).

Conclusion:
The childbearing age women knew most aspects of STIs, but had gaps of knowledge. They believed that STIs are curable, which influenced their attitudes towards STIs. Health care professionals are challenged to educate patients on STIs on an ongoing basis.
Quantile Regression Analysis of Modifiable and Non-Modifiable Predictors of Stroke among Adults in South Africa
Authors: Chikobvu Delson , Matizirofa Lyness 
Published: September 2021

Background:
Stroke is the second largest cause of mortality and long-term disability in South Africa (SA). Stroke is a multifactorial disease regulated by modifiable and non-modifiable predictors. Little is known about the stroke predictors in SA, particularly modifiable and non-modifiable. Identification of stroke predictors using appropriate statistical methods can help formulate appropriate health programs and policies aimed at reducing the stroke burden. This study aims to address important gaps in stroke literature i.e., identifying and quantifying stroke predictors through quantile regression analysis.

Methods:
A cross-sectional hospital-based study was used to identify and quantify stroke predictors in SA using 35730 individual patient data retrieved from selected private and public hospitals between January 2014 and December 2018. Ordinary logistic regression models often miss critical aspects of the relationship that may exist between stroke and its predictors. Quantile regression analysis was used to model the effects of each predictor on stroke distribution.

Results:
Of the 35730 cases of stroke, 22183 were diabetic. The dominant stroke predictors were diabetes, hypertension, heart problems, the female gender, higher age groups and black race. The age group 55-75 years, female gender and black race, had a bigger effect on stroke distribution at the lower upper quantiles. Diabetes, hypertension and cholesterol showed a significant impact on stroke distribution (p < 0.0001).

Conclusion:
Most strokes are attributable to modifiable factors. Study findings will be used to raise awareness of modifiable predictors to prevent strokes. Regular screening and treatment are recommended for high-risk individuals with identified predictors in SA.

Published: September 2021

The incident rate has been widely used to indicate safety performance. The incident rate of a company can be compared with the national or international incident rate within similar industry or among different type of industries. The comparison is particularly very useful as a safety benchmark to gauge performance with other companies in the same business area. However, many existing methods produce the annual incident rate, which has been formulated on an annual basis. This will lead to incompatibility of the method used in calculating the incident rate for a project that runs for a specific period. This is because the annual incident rate does not consider the duration of the project; it becomes less meaningful in indicating the safety performance of project-based activities such as those in construction industries. The proposed method which is Project-Based Incident Rate (PIR) is found to be able to reflect the actual situation of project-based companies better than the existing annual incident rate method, and it is also can be expressed both on a monthly and yearly basis.

Published: September 2021

The work discusses method development and validation. An uncomplicated, accurate, and straightforward method was developed for the drug Esomeprazole in bulk as well as Pharmaceutical dosage form. NaOH was used as the solvent. The maximum wavelength (ʎ max) for Esomeprazole was found to be 305nm. The validation was performed as per International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines for Accuracy linearity, precision, Limit of Detection (LOD) and Limit of Quantification (LOQ). Esomeprazole's recovery percentage (%) was 100.20%, respectively. Linearity for Esomeprazole was observed between 5-25µg/ml, respectively. Regression equation y=0.0407x-0.0122, regression coefficient (r²) is 0.9963 for Esomeprazole. Inter day and intraday precision were checked, % relative standard deviation values were less than 2. The regression equations were used to derive the Limit of Detection (LOD) and Limit of Quantification (LOQ) values. LOD value was found to be 0.734 µg/mL and LOQ value was 2.224 µg/mL for Esomeprazole. The assay of the marketed formulation was performed, which was between 98-102%. So the method developed was simple and economical that can be adopted for routine tests.
Hadith Scholars Personality Development Review: Relevance in the development of psychological behavior
Authors: Zainal Badri Khairul Nizam Bin 
Published: September 2021

One of the definitions of personality involves character patterns that include feelings, thoughts and actions. Based on this definition it turns out that personality can not run away from the field of psychology. Personality traits are biological while personality values are environmental products influenced by culture, education and life. In the study of modern psychology, thought-based traits that are in the cognitive domain are higher than emotional traits in relation to values. In the tradition of Islamic science, there is a special traits, which is the yardstick of superior personality; that is, Al-‘Adalah or is called adil (fairness). Related to the trait of adil is the trait of dhabit (strong memory). A qualitative study using this library approach seeks to trace the properties possessed by hadith scholars, who once inspired the West to apply those attributes in their intellectual work. Studies have found that these properties have unique characteristics because of their ability to integrate ontological, epistemological and axiological dimensions and also balance the role of cognitive and affective domains in human beings that direct human physiological and psychological behavior in a positive direction.

Published: September 2021

The estimation of the amounts of Surface runoff resulting from rainfall in the water basins is of great importance in water resources management. The study area (Bahr Al-Najaf) is located on the western edge of the plateau and the southwestern part of the city center of Najaf, with an area of 2729.4 (km2). The soil and water assessment tool (SWAT) with ArcGIS software was used to simulate the runoff coming from the three main valleys (Kharr (A and B)), Shoaib Al-Rahimawi, and Maleh), that contribute the flow to the study area. The results of the model showed that the SWAT software was successfully simulating the flow conditions based on the coefficient of determination (R2), the Nash coefficient (NSE), P-factor, and R-factor for calibration (validation) ranged between 0.59-0.62 (0.51-0.59), 0.59-0.66 (0,.60-0.62), 0.57-0.76 (0.62-0.76), and 0.58-0.74 (0.55-0.70) respectively for these valleys. Moreover, the sensitivity results revealed that the most sensitive parameters in (SWAT-CUP) SWAT calibration and uncertainty programs are the curve number (CN2) for the runoff, soil available water capacity (SOL_AWC), and Saturated hydraulic conductivity (Soil_k), according to the calibration results for the main three valleys related the study area. Three hypothesis scenarios were implemented according to the assumed amount of precipitation that would submit a water level of 16,18, and 22 (m.a.m.s.l.) which would result in filling with the bounded lake, the whole study area, and exceeding the boundaries to flood part of the ancient Najaf City.

Abstract
This study presents the results of thermal cycling experiments on thermal barrier coatings deposited using hybrid water/argon-stabilized plasma (WSP-H) torches. Topcoats produced from YSZ suspensions and powders were successfully prepared and evaluated by thermal fatigue testing. Quad-layer coatings with topcoats consisting of yttria stabilized zirconia, gadolinium zirconate, and yttrium aluminum garnet were also prepared and tested at high temperatures and thermal gradients. The results obtained show the potential of WSP-H technology for applications where protection of large components or deposition of thick coatings are required.

Published: September 2021

Abstract
Nickel-aluminum alloys are widely used in harsh environments due to their corrosion resistance, high melting temperature, and thermal conductivity. In this work, Ni-5wt%Al coatings were deposited by twin-wire arc spraying (TWAS) on tool steel using a design of experiments approach to study the effect of process parameters on coating microstructure and performance. Test results presented in the form of process maps show how N2 pressure, stand-off distance, and current affect in-flight particle velocity and temperature as well as coating thickness and oxide content. Using this information, optimized coatings were then deposited on test substrates and subjected, along with uncoated tool steel, to several hours of molten aluminum attack. The coated samples showed no signs of physical or chemical damage, whereas the uncoated substrates experienced oxidation, aluminum infiltration, and formation of Fe-Al intermetallics.

Soil property variability in a humid natural Mediterranean environment: La Rioja, Spain .
Authors: Navarro Pedreño José , Gómez Lucas Ignacio , Meléndez-Pastor Ignacio 
Published: September 2021

Estimating the spatial variability of soil properties is significant for evaluating environmental impacts. For example, many soil properties are directly used in the modelling of environmental processes such as global climate change. These aspects have not previously been studied at this level in La Rioja (a region of Spain with a humid Mediterranean environment). The intention of this study was to provide quantitative information on soil assessment and mapping methods for natural soils in a humid Mediterranean environment. The properties considered included: pH and organic matter, calcium carbonate and clay contents. For testing, samples were selected from several different soil types which, in theory, were only affected by pedogenetic processes and had developed on different parent materials. More than half of the samples did not contain any CaCO<sub>3</sub>, while the rest of the samples presented a variety of CaCO<sub>3</sub>, forms, with high percentages being present in certain cases (up to 65% on the surface). It was possible to establish two different areas: one predominantly acidic and the other principally basic. The predominately basic samples were due to the high percentage of carbonate in the parent materials. The clay content on the surface was similar to that in the subsurface layers. Finally, the organic matter contents in the uppermost layers presented average values of 3.9%,with a range of from 0.3 to 17.5%. The major variations in soils were determined by soil type (therefore by soil forming processes), parent material composition, and vegetation type. This study reveals that these methods are useful to determine the spatial distribution of some soil properties in undisturbed soils. The contour maps of soil property variability could be used to improve future sampling designs and management decisions.
Dark humic alluvial paleosols in Central and Southern Mexico: Micromorphological indicators of Late Pleistocene megafauna habitats .
Authors: Tovar Rosa E. , Solís Berenice , Sedov Sergey , Solleiro Elizabeth 
Published: September 2021

During the Late Pleistocene, Mexico had a richer fauna than today with many different forms of megafauna that are now extinct. However, the ecosystems they inhabited and the particular ecological niches that they occupied are still poorly understood. Most of the findings of Pleistocene megafauna have been in alluvial deposits that present rich opportunities for paleoecological studies using paleopedological records. Floodplain paleosols commonly are poorly developed. However, micromorphological analysis provides information about the grade of development of the soil at a microscale, discriminating between genetic and sedimentary processes; thus helping in the identification of the environmental setting in which they formed. We analyzed the micromorphology of six pedogenetic units in the sequences of Santa Cruz Nuevo and Axamilpa, in the south of Puebla, and Huexoyucan, in the state of Tlaxcala. These pedosequences correspond to the second half of marine isotopic stage 3 (MIS3), MIS2 and the early Holocene. All studied units are characterized by strong pigmentation with dark humus. The micromorphological analysis of MIS3 paleosols reveals aquatic conditions with evidence of freshwater biota and microlamination as well as pedogenetic features of hydrogenic carbonate precipitation and redoximorphic processes. The dark paleosols of MIS2 and the early Holocene demonstrate signs of stronger coprogenic aggregation, weathering and fewer gleyic features. Comparison with modern soils shows that the latter were formed under better-drained, aerated conditions that exclude redoximorphic processes. We conclude that the dark colored Pleistocene paleosol units are indicative of different paleo-landscapes: wetlands in the MIS3 and moist meadows in MIS2 – early Holocene. The swampy ecosystems could play an important role as a megafauna habitat.
