Authors: Tang Shu Hui , Lee Lin Zhi , Arsad Agus , Zakaria Zaki Yamani , Ahmad-Zaini Muhammad Abbas 
Published: July 2023

Abstract
At present, possible utilization of oil-containing sludge so as to achieve the sustainable environment has become a subject of considerable interest. The oleochemical factory generates nearly two metric tons of sludge per day from the effluent processing plant. Its disposal is costly and strenuous towards the environment, therefore different alternatives to handling and utilization were studied. The sludge and its derivatives were characterized for elemental composition, proximate analysis, ash and oil constituents, surface analysis, leaching tests and calorific value. Results show that the oil-containing sludge is rich in carbon, calcium, and iron. It has a high calorific value of 33.8 MJ/kg, that is partly attributed to the oil content of 68 %. These preliminary characteristics data offer insight into several promising applications of converting “trash” into “treasure” towards sustainable environment.
Study of the Impact of Housing Affordability on the Fertility Rate in Bulgaria (2014–2021): A Regional Aspect
Authors: Stoenchev Nikolay , Hrischeva Yana 
Published: July 2023

Abstract
The present study is devoted to the influence of housing affordability on the fertility rate in Bulgaria. Both data published by NSI and data obtained by individual request were used. Housing affordability is a factor and is represented as the ratio of the average price of a 70 m2 apartment and the average gross salary of an employed person, as well as the ratio of the average housing price and the average income per person in a household. Fertility has the role of an outcome variable and is represented by the gross fertility rate, average age of the mother at the birth of the first child and at the birth of a child, number of live births by age of the mother and total fertility rate. Such lag values of the factor variable were used due to the long period from the moment of availability of housing to its acquisition, completion, furnishing and commissioning, and the long biological period from the decision to implement reproductive intentions to the birth of a child. The Pearson correlation coefficient was used to assess the direction and strength of the relationship. A strong negative relationship is found between housing affordability and fertility rate, except for the relationship with the total fertility rate, which is weakly positive. The change in the lag has a minimal effect on the value of the correlation coefficients. Therefore, a conclusion can be made that children are mostly born where housing affordability is low and parents are forced to raise them in unsuitable housing conditions.

Published: July 2023

Abstract
Intensification of extreme rainfall-runo events in arid and semi-arid regions because of climate change induce the water erosion that contributes considerably to the loss of vegetal layers of soils and reduce the storage capacity of dams by silting of transported sediments from the watershed to the impoundment. This paper aims at proposing means for protecting the Mghila dam against silting by identification and delimitation of vulnerable areas to water erosion. This dam, built in the North-West of Algeria, ensures irrigated cultivation. Topographical, geological, and land use characteristics of the watershed were analyzed using the geographic information system (GIS). Analysis of results has allowed the identification by area percentage four-vulnerability classes with sensitivity to the water erosion: low(18.89%), medium (13.08%), high (65.05%) and very high (8.38%). The spatial distribution of the lithological substratum friability, the vegetation cover and slope degrees have led to the development of an e cient strategy for the watershed management in order to reduce the e ect of water erosion on soil degradation and silting of the Mghila dam.
Computer-simulated degradation of CF3Cl, CF2Cl2, and CFCl3 under electron beam irradiation
Authors: Kabasa Stephen , Sun Yongxia , Chmielewski Andrzej G. , Nichipor Henrietta 
Published: July 2023

Abstract
Electron beam treatment technologies should be versatile in the removal of chlorofluorocarbons (CFCs) owing to their exceptional cross sections for the thermal electrons generated in the radiolysis of air. Humidity, dose rates, O2 concentration, and CFC concentration influence the efficiency of the destruction process under electron beam treatment. Computer simulations have been used to theoretically demonstrate the destruction of chlorotrifluoromethane (CF3Cl), dichlorodifluoromethane (CF2Cl2), and trichlorofluoromethane (CFCl3) in the air (N2 + O2: 80% + 20%) in room temperature up to a dose of 13 kGy. Under these conditions, it is predicted that the removal efficiency is in the order CF3Cl (0.1%) < CF2Cl2 (7%) < CFCl3 (34%), which shows the dependence of the process on the number of substituted Cl atoms. Dissociative electron attachment with the release of Cl– is the primary process initiating the destruction of CFCs from the air stream. Reactions with the first excited state of oxygen, namely, O(1D), and charge-transfer reactions further promote the degradation process. The degradation products can be further degraded to CO2, Cl2, and F2 by prolonged radiation treatment. Other predicted products can also be removed through chemical processes.

Published: July 2023

Abstract

Background
It is currently well-known that inflammation plays an essential role in all phases of atherosclerosis. Recent CT studies showed that atherosclerotic plaques found in the right coronary arteries (RCA) display a greater number of features that increase their susceptibility to destabilization compared to plaques found in left coronary arteries (LCA). COVID-19’s impact on regional coronary inflammation is not well understood, despite extensive research on its effects on cardiovascular diseases.

Objectives
This study aimed to evaluate the regional differences between local inflammation at the level of left versus right coronary circulation in patients who had CCTA examinations for chest pain in the early stages after COVID-19 infection.

Methods
In total, 172 patients with chest pain and CCTA data available were included in the study, divided into two groups: Group 1 (n = 80) with recent COVID-19 infection, and Group 2 (n = 92) with no known COVID infection. Attenuation of epicardial fat density was calculated in all patients using the FAI technology available from Caristo (Oxford, UK), and the associated FAI score and CaRi Heart® score of related cardiovascular risk were calculated.

Results
CaRi Heart® Risk (p < 0.0001) and Duke Score (p < 0.0001) were significantly higher for the COVID-negative patients, who presented a significantly higher FAI score (p = 0.001). This difference was also present in all the three coronary arteries: LAD (p = 0.05), LCX (p = 0.05), RCA. In the COVID-19 positive group the FAI score was significantly higher at the RCA level (p = 0.0002), but the non-COVID-19 presented no significant differences of inflammation levels between the left and right coronary circulation.

Conclusions
COVID-19 infection is associated with a higher risk of inflammation in the pericoronary epicardial fat. In post- COVID-19 patients, this inflammation seems to be more pronounced at the level of the RCA, which indicates a potential role of local hemorheological factors in the complex process of inflammation-mediated plaque vulnerabilization after COVID.

The curriculum is a government policy in the field of education determined by the government. The curriculum has continued to change according to the times and advances in science and technology. This study uses a qualitative method by producing descriptive data as an observable social reality, namely the educational curriculum. The social reality is then analyzed using public policy theory. This article concludes that the curriculum as a political policy from the Indonesian government in the field of education is a logical consequence of social change and development of science. From 1999 to 2013 there were three changes to the curriculum, namely the Competency-Based Curriculum (KBK), the Education Unit Level Curriculum (KTSP) and the 2013 Curriculum (K-13). Each curriculum has its own focus and emphasis point. The purpose of the curriculum changes carried out by the government from a theoretical point of view of public policy is oriented towards fulfilling the needs and interests of the community. So that the curriculum can still be adapted to social changes, scientific and technological developments that occur in society in Indonesia and the wider world

Driving Oil and Gas Well Delivery Performance with Value Creation Events
Authors: Dagogo Sopriala Omubo  , Adedotun Babatunde Ogunwale  
Published: July 2023

Oil and gas well delivery involves the execution of well projects, with attention to safety, design specification, desired well objectives, planned time, and agreed budget. These projects involve drilling, completion, work-over, and decommissioning/restoration (also known as abandonment) activities.
Performance, with respect to the oil and gas well delivery process, is the result of comparing the actual versus plan of the above-mentioned indicators. This means, to obtain an accurate performance report, there must be benchmarks, clearly agreed upon, prior to the commencement of well execution. Plan-beating performance is not achieved without a deliberate strategy. One of the major contributors to such is the value derived from discussions about the well project. These discussions occur in what could be termed value-creation events.
Value creation events are simply discussion sessions organized with the intent to derive value that has the potential to improve well-delivery performance. Attendees are largely the stakeholders in the project, including the facilitator of the event. These value-creation events are classified based on the timing of the event relative to the project execution as pre-execution or post-execution events.
This paper discusses various value creation events under these classifications and how they are used to drive well delivery performance, with a focus on the value obtained to aid time and cost reduction and delivery of stated well objectives at the minimum.

Published: July 2023

This study examines the possible factors that contribute to the positive and negative attitudes of students towards the learning of English Language in some selected junior high schools in the Asante Akyem North District of the Ashanti Region. This study offers a broad overview of the field of individual differences in the teaching and learning of English language. All learners are endowed with different mindsets that they employ while performing various activities in their daily lives. Many teachers and researchers believe that learning preferences or learning styles can be used advantageously to enhance English language study and motivate students.
The objectives of this study were to investigate the attitude of students towards the study of English and the competence level of their English. The participants were interviewed and asked to complete questionnaires that would reveal their attitudes toward learning English.
The findings revealed that the students are dominant towards the learning of English; their levels of attitude are influenced by many factors such as lack of adequate and well-qualified English teachers, lack of need-based facilities, and social inadequacies.
The researchers provided recommendations for language teachers and other stakeholders to develop programmes that would encourage and motivate students in their learning of the English language.

Статья посвящена результатам исследования методами нейтронной томографии и дифракции двух серебряных перстней конца I - перв. пол. II в. н. э. и трех бронзовых монет первой трети III в. н. э. из раскопок могильника римского времени Фронтовое 3 (Юго-Западный Крым). Исследования серебряных корродированных перстней, выполненные методом нейтронной томографии и дифракции, позволили диагностировать процесс коррозионного растрескивания под напряжением, возникающего в результате применявшейся в римское время техники изготовления перстней (ковка с наклепом). Анализ фазового состава металла римских фоллисов по методу нейтронной томографии и дифракции показал, что они были изготовлены из тройной бронзы без присадки серебра; это отличает рецептуру их сплава от применявшегося для выпуска таких монет в западных провинциях Римской империи. Методом нейтронной томографии также установлено отсутствие следов серебрения на поверхности фоллисов перв. трети IV в. н. э. из Фронтового 3
The paper describes results of the analysis of two silver rings dating to the end of the 1st - first half of the 2nd centuries AD and three bronze coins from the first third of the 3rd century AD found during excavations of Frontovoye 3. The site is a cemetery of the Roman period in Southwestern Crimea. The analysis of corroded silver fingerrings was performed using methods of neutron tomography and diffraction. Methods of neutron structural diagnostics offered an opportunity to determine the process of corrosion cracking caused by the forging technique used in the Roman time. The analyzed phase composition of the metal the Roman folles were made from demonstrated that three-component bronze without silver addition was used in their production, which means that their formula is different from that applied to mint such coins in western provinces of the Roman Empire. The neutron tomography method did not find any traces of silver plating on the surface of the folles dating to the first third of the 4th century AD discovered at Frontovoye 3.

Published: July 2023

Статья посвящена введению в научный оборот и анализу серии клейм на тонкостенных красноглиняных сосудах, обнаруженных при изучении Елизаветовского городища на Дону в одном из строительных комплексов второй половины IV в. до н. э. Как правило, находки подобного рода связываются исследователями с мерными сосудами и являются достаточно редкими для памятников скифо-античного времени Северного Причерноморья. В материалах Елизаветовского городища такие находки обнаружены впервые. Присутствие на этом поселении фрагментов таких сосудов, а также обнаруженные в разные годы свинцовые гири свидетельствуют о применении в торговых операциях на городище стандартизированной системы мер и весов и развитии здесь не только оптовой, но и мелкой розничной торговли.
The paper introduces into scientific discourse and analyzes a series of stamps on red clay thin-walled vessels found during excavations of the Elizavetovskoye fortified settlement in the Don region in one of construction complexes dating back to the second half of the 4th century BC. Scholars tend to link such finds to measuring vessels which are rather rare for Scythian-Ancient Greek sites in the North Pontic region. These vessels are the first finds of this type discovered at the Elizavetovskoye settlement. Presence of fragments of this kind of vessels as well as lead weights discovered in various years suggest the use of a standardized system of weights and measures in trade transactions and development of not only wholesale but also retail trade at Elizavetovskoe settlement on the Don.
