INVESTIGATION OF GAS-OIL RELATIVE PERMEABILITY PARAMETERS IMPACT ON THE FIELD DEVELOPMENT EFFICIENCY IN LOW PERMEABLE RESERVOIRS
Authors: Povalyaev A. A. , Fedorov A. E. , Antonov M. S. , Dilmukhametov I. R.
Published: November 2023

Development of hard-to-recover reserves in low-permeable oil deposits is one of the main sources to maintain resources base in light of continuous depletion of conventional reserves. Meanwhile, the new development zones tend to have an even worse reservoir characteristic, which leads to the evolution of field developments strategies.  

In particular, vast amount of hard-to-recover reserves are located in the areas where reservoir pressure maintenance by water injection is inefficient and, therefore, these deposits are developed on depletion regime which evolves into solution gas drive when reservoir pressure drops below saturation pressure. The efficient planning of field development in these cases is complicated by the uncertainties in production forecast associated with models parameters describing the multiphase flow.

This study presents the analyze the impact of the parameters, describing relative permeability on gas-oil system, on the history matching quality and the production forecast in low-permeable reservoirs that are developed under solution gas drive regime.

The main tasks of the study were the following:

- analyze the typical shapes of relative permeability curves applicable for description of different multiphase flow regimes, namely solution gas drive when the gas liberated from oil forms a continuous media and the gas injection when gas phase in introduces from the external source;

- evaluate the possibility to perform an accurate history matching using different types of relative permeability curves;

- evaluate the impact of relative permeability curves modifications on the production forecast in the reservoir simulation models.

The results of the study can be used in field development projects for evaluation of production potential of low-permeable reservoirs developed under depletion regime with the decrease of in-situ pressure below bubble point.
CALCULATION OF UNDERGROUND PIPELINE OVERHAUL TECHNOLOGICAL PARAMETERS
Authors: Azmetov Kh. A. , Khasanov R. R. , Shaibakov B. R.
Published: November 2023

Overhaul with pipeline lifting  is one of the most frequently used repair methods in pipeline system technical operation in the oil and gas industry. Using this repair method, the anti-corrosion protective outer coating that has lost its protective properties is replaced. If necessary, pipe walls are repaired. Organizations operating pipelines are equipped with modern methods and means for determining the technical condition of the protective coating and the pipes themselves. The technical operation system allows timely detection of defective sections and carrying out appropriate repairs, ensuring reliable and efficient pipeline operation. At the same time, the overhaul of the pipeline, especially with its lifting, is an important and complex technological process. Pipeline lifting leads to the appearance of additional stresses in the pipe walls, which were not taken into account at the pipeline design stage. These stresses are added to the stresses from the temperature difference and pressure in the pipe cavity of the pumped product. The total stresses, taking into account the actual technical condition of the operated pipelines, can reach significant values that affect the strength of the pipelines and the safety of the overhaul. At the same time, regulatory documents for pipeline technological parameters calculating do not take into account the forces and stresses in the pipe wall from the effects of temperature differences and pressure in the pipe cavity. In this regard, it is necessary to improve the existing pipeline technological parameters of the overhaul with lifting, taking into account all loads and impacts, as well as the strength of the pipes and the safety of the overhaul.

In addition, in well-known calculations, the required lifting height of the pipeline at the place of installation of cleaning and insulating machines is not the initial parameter, which complicates the provision of the specified lifting height in order to create normal operating conditions for the machines.

The purpose of the work is to ensure the strength of pipes and the safety of overhaul with lifting of the existing pipelines based on the improvement of the calculation of repair technological parameters. Improving the calculation includes taking into account the longitudinal forces acting in the pipeline when it is lifted and taking the required lifting height at the places of installation of cleaning and insulating machines as an initial parameter.

Research methods - analysis and theoretical studies of the stress-strain state of the existing pipeline when it is lifted by pipe-laying machines.

The dependences of the technological parameters of a overhaul with pipeline lifting on the longitudinal forces acting in the pipeline in the lifting section and lifting heights at the places of installation of machines for pipeline cleaning and insulating are obtained.

An Appraisal of the Requirements for the Validity of a Customary Marriage in South Africa, Before and After the Recognition of Customary Marriages Act 120 of 1998
Authors: Nkuna-Mavutane Matthews Eddie , Jamneck Juanita
Published: November 2023

This article appraises the requirements for the validity of a customary marriage. It peruses two eras separated by a statute called the Recognition of Customary Marriages Act 120 of 1998 (RCMA). Prior to delving into what the requirements for validity before the RCMA were, the article differentiates between peremptory and directory provisions. These terms are usually applied in interpreting statutes. They also find application in determining the requirements of the validity of customary law. The era before the RCMA lists essential requirements for a valid customary marriage. The gist of these requirements is as follows: consent of the bride and bridegroom (spouses), consent of the bride’s father or guardian (parents), payment of lobolo, the handing over of the bride and the absence of a civil marriage by either spouse. If any of these requirements were not met, there was no valid customary union. The RCMA added more requirements which seem to address formal and customary law requirements. Both prospective spouses need to be 18 years or older, with certain exceptions, and must consent to getting married in terms of customary law. These requirements are peremptory. The customary law requirements relate to the negotiation and celebration of such a marriage. These requirements remain essential. Unlike formal requirements, these requirements allow indigenous African people a certain latitude. As a result, they are directory. This article further deliberates on certain issues regarding the requirements of customary marriages that became contentious. This includes the delivery of lobolo, the handing over of the bride, polygamous and dual marriages, and the registration of customary marriages. In conclusion, it is shown that customary law is a rapidly growing independent source of law. The requirements for validity must be comprehended with this flexibility in mind and should not unnecessarily be held as being static.
The Tsetse Fly Perched on the Scrotum: Publishing Problems in Academic Journals
Authors: Diala Anthony C , Hussein Nejat
Published: November 2023

South Africa's research incentive system rewards faculty members and affiliates for publishing in outlets that are "accredited" by the Department of Higher Education and Training. This arguably perverse incentive makes academic research a potentially aggressive numbers game. It is compounded by factors such as undue delay in peer review, difficulty in securing expert evaluators, and poor understanding of who constitutes a "peer". Despite the "publish or perish" pressure on researchers and the prohibition of the parallel submission of manuscripts by many journals, there is negligible research on publishing problems in South African journals. Informed by a literature survey, editorial experience and conversations with colleagues, this article seeks a dialogue about these problems, which it characterises as a tsetse fly perched on the scrotum. On the one hand, the current incentive system commodifies outputs and diverts attention from building knowledge with socially responsive research to building the financial coffers of universities and authors. On the other hand, inappropriate editorial interpretations of a "peer" and the gratis nature of peer evaluation encumber the publishing process. We argue that this situation erodes academic excellence, encourages the growth of predatory journals, and potentially harms national development.
Constitutional Damages – a Stagnant or a Changing Landscape?
Authors: Mukheibir Andre
Published: November 2023

Section 38 of the Constitution of the Republic of South Africa, 1996 provides for appropriate relief where a right in the Bill of Rights has been infringed. In Fose v Minister of Safety and Security 1997 3 SA 786 (CC) the Constitutional Court raised the question of "appropriate relief" with reference to section 7(4)(a) of the Constitution of the Republic of South Africa Act 200 of 1993. In the Fose case the plaintiff claimed "punitive constitutional damages" together with delictual damages. While the court did not rule out an award for damages for the infringement, it did not award constitutional damages in that instance, specifically because the plaintiff claimed "punitive constitutional damages". The Fose case has been followed by most of the cases heard in the years after Fose was decided. In most instances where constitutional damages were claimed the courts, following Fose, have not awarded constitutional damages where delictual damages were available. The rules relating to constitutional damages are casuistic and it is submitted that the principle of subsidiarity could form a foundational principle to solve the problem of casuistry in this regard.
The Legal Framework Governing Traditional Leaders' Role in Land Use Planning in South Africa
Authors: Du Plessis Elmien
Published: November 2023

This article investigates the legal framework governing the role of traditional leaders in land use planning, through a historical gaze at the nature and authority of traditional leadership in South Africa. It is through this brief historical discussion that the influence of colonial and apartheid concepts of traditional leadership, as concretised in legislation, comes to the fore. This then creates a basis from which the Traditional and Khoisan Leadership Act 3 of 2019 and the Spatial Planning and Land Use Management Act 16 of 2013 are explored.
Hands off our Intangible Cultural Heritage - Khoin v Jenkins in re: Observatory Civic Association v Trustees for the Time Being of the Liesbeek Leisure Properties Trust
Authors: Kantor Peter
Published: November 2023

This case note analyses an appeal decision (Khoin v Jenkins in Re: Observatory Civic Association v Trustees for the Time Being of the Liesbeek Leisure Properties Trust [2023] 1 All SA 110 (WCC)) handed down in 2022 by the Western Cape High Court, its purpose being to identify the strengths and weaknesses of the decision and to comment on possible future developments. The text of the judgment is interpreted in the light of judicial precedent, literature and domestic (South African) and international law. One of the key findings is that "intangible heritage" is an integral part of both domestic and international law, and the Khoin-case gives judicial recognition to the concept as a part of South African heritage law. One of the main criticisms levelled against the judgment is that it does not adhere to judicial precedent in failing to find that the right to consultation of First Nations Peoples before administrative action is taken that allegedly violates their constitutional rights to intangible heritage is sufficient to satisfy the test for the existence of a prima facie right for the purposes of obtaining an interim interdict.
A Transparência Como Dimensão da Qualidade: A Propriedade dos Média e os Desafios da (In)visibilidade
Authors: Figueira Alexandra , Costa e Silva Elsa
Published: November 2023

O princípio da transparência tem sido considerado como uma resposta política consensual às preocupações com a falta de pluralismo e de confiança no jornalismo. De caráter multidimensional, a transparência relativa à propriedade é uma das exigências legais mais correntes. O foco nos “donos” dos média não é recente, dado o impacto que a propriedade pode ter nos conteúdos produzidos. A propriedade é, por isso, considerada essencial quando se avalia a qualidade no jornalismo. Em Portugal, a propriedade dos média é sujeita a regras de transparência, que implicam a divulgação de informação sobre a estrutura empresarial e dados financeiros, cabendo à Entidade Reguladora para a Comunicação Social monitorar o seu cumprimento. O modo como as empresas de média em Portugal têm respondido às novas exigências legais não tem sido investigado, apesar de essa análise poder contribuir para se compreender os desafios que se levantam ao exercício de um jornalismo independente e plural. O objetivo deste estudo é assim perceber de que modo o princípio da transparência dos média tem sido recebido pelo mercado em Portugal, averiguando os incumprimentos e as objeções levantadas à divulgação da informação requerida. Esta análise, realizada a partir das deliberações da Entidade Reguladora para a Comunicação Social, evidencia o papel central da escala na adequação ao novo enquadramento legal: os incumprimentos declarativos ou pedidos de sigilo partem sobretudo das empresas de menor dimensão, detentoras de média locais ou de revistas especializadas. Ainda, a informação de caráter financeiro é a mais crítica. Estes dados apontam para fragilidades a nível financeiro, o que pode levantar dúvidas relativamente à independência dos média face a agentes externos. Por outro lado, o princípio da visibilidade da transparência não contribuiu para a discussão sobre o cenário mediático em matéria de concentração da propriedade ou de pluralismo, o que demonstra a insuficiência deste princípio como principal política relativa à propriedade dos média.
Early failure of prosthetic valve presenting with acute heart failure
Authors: P Candela , L Ajello , MCE Valerio , P Camarda , V Mineo , EV Castelluccio , E Rebulla
Published: November 2023

Background: Early failure of cardiac biological prostheses refers to the deterioration or malfunction of the valve sooner than expected. These prostheses are designed to last for many years, even decades, but in some cases, they may fail within a much shorter timeframe. Early failure can manifest in various ways, including structural issues, valve stenosis, regurgitation, and reduced functionality. Understanding the causes of early failure is crucial for improving patient outcomes. Case presentation: We present the case of failure of a biological prosthesis implanted five years prior; the onset was rapid and acute (worsening dyspnea three days before access to the emergency room). A transcatheter mitral valve replacement was planned. Unfortunately, the patient expired before the procedure. Discussion: Although rare, early failure of biological valve prosthesis is possible. So, when treating a patient with a history of valve surgery presenting with acute heart failure, the suspicion of valve failure should be always considered.

Published: November 2023

This study reports the one health concept, prevalence, and antimicrobial susceptibility patterns of Salmonella and Escherichia coli isolated from raw and ready-to-eat (RTE) meats sold in cities of Lagos State, Nigeria. The conventional method of isolation was used to isolate E. coli and Salmonella spp. on their respective selective media from fifty meat samples obtained from abattoirs, open display, and packaged products at various locations in the state and was confirmed by Gram’s reaction and biochemical tests. Thirty-three E. coli and Twenty-seven Salmonella spp. were isolated with the overall prevalence rate recorded as 72% and 68% respectively. The isolated bacteria were subjected to antimicrobial susceptibility testing on nine different antibiotics using the agar disc diffusion method. All the Salmonella were resistant to at least one antibiotic while two E. coli isolates showed susceptibility to all the antibiotics used in this study. Of the 33 E. coli subjected to antimicrobial testing, 84.8% were susceptible to gentamicin, 81.8% susceptible to ciprofloxacin, and 75.8% susceptible to Augmentin. A lower susceptibility pattern was observed on Salmonella with 74.1% of the Salmonella being susceptible to ciprofloxacin and gentamicin, and 70.4% susceptible to azithromycin. Gentamicin was the most effective antibiotic while amoxicillin was found to be least effective against E. coli and Salmonella isolated from the meat samples used in this study. The multiple antibiotic resistance (MAR) index of Salmonella ranged between 0.11-0.67 while E. coli ranged between 0-0.89. E. coli was found to be more resistant than Salmonella and the bacteria isolated from RTE meats showed higher MAR than those isolated from raw meats.

Backgraund. Pneumolysin (Ply) is a hemolytic toxin of Streptococcus pneumoniae (S. pneumoniae) expressed by all strains of pneumococci. The use of sandwich enzyme-linked immunosorbent assay (ELISA) can be a simple, fast and effective way of its qualitative and quantitative determination in biological fluids.

Aim. To develop and evaluate the specificity of sandwich ELISA test system for qualitative and quantitative determination of recombinant Ply (rPly) of S. pneumoniae.

Materials and methods. Immobilized on the solid phase rabbit’s polyclonal antibodies (pAbs) to rPly were used as recognition antibodies in sandwich ELISA. The studied antigens were added to the pAbs (rPly). The reaction was manifested by using detecting mouse monoclonal IgG1 (rPly) – antibodies conjugated with horseradish root peroxidase. The specificity of the test system was evaluated when using recombinant α-hemolysin (rα-Hly) and water-soluble S. aureus antigens as reference preparations.

Results. Using sandwich ELISA, rPly was detected at a concentration of 0.15 µ / ml. The test system was characterized by specificity, which was confirmed by the absence of reaction with recombinant rα-Hly of Staphylococcus aureus (S. aureus). Reference preparations of water-soluble surface antigens of S. aureus strains No 209, 1986,1991 and Cowan I gave a false positive reaction due to the presence of protein A (SpA) in their composition, a thermostable surface protein expressed by many strains of staphylococci capable of binding immunoglobulins via Fc-fragment or Fab fragments of the V3H domain of the B cells receptor. A negative reaction was obtained with antigens from the S. aureus wood 46 strain, which does not have the spa gene encoding SpA expression. The presence of protein A in preparations of water-soluble S. aureus antigens was confirmed in the ELISA inhibition assay.

Conclusion. Sandwich ELISA has been developed for qualitative and quantitative determination of S. pneumoniae Ply. The conducted studies have confirmed the specificity of the test system.

Authors: Yuzhakova S.A.
Published: November 2023

The article, created on the basis of the “Path of Childhood” program, examines the problems of early comprehensive assistance to children with disabilities and their social adaptation into society, which are currently recognized as extremely relevant in the field of education and healthcare. Also, the authors talk about the existence of a socially significant problem associated with the need for early prevention of developmental disorders in a more expanded form than what is currently used, and also requires other technological solutions than those implemented by health and education authorities. The program described in the article is intended for specialists working with early age children in educational institutions. The presented methods and technologies can be implemented by educational psychologists, special education teachers, and speech therapists. The article also describes the maximum necessary conditions for ensuring work with disabled children, children with disabilities, children who do not attend preschool educational institutions and their families. The program “Path of Childhood” passed an examination to verify the evidence base within the section “Evidence-Based Approach in Psychology and Education” of the Scientific Expert Council of the Federal State Budgetary Educational Institution of Higher Education Moscow State University of Psychology & Education and was awarded a certificate of conformity (registration number “6/17-pr” dated July 25, 2023). Based on the results of the examination, it was found to comply with the standards of programs and technologies with proven effectiveness for the educational and social spheres at the stage of pilot projects and was recommended for inclusion in the register of exemplary correctional-developmental, correctional-rehabilitation and preventive programs for the activities of a teacher-psychologist (psychologist in the field of education) and replication in educational and social institutions.

Published: November 2023

School anxiety is understood as a condition that is accompanied by anxiety, tension, uncertainty and stress related to educational activities, social relations and behavior at school. Modern research shows the influence of a high level of school anxiety on a student’s self-esteem and self-confidence, a decrease in his educational motivation and the effectiveness of educational activities, as well as the emergence of problems in establishing relationships with classmates and teachers. The article presents the results of standardization of the modified Russian-language version of the “School Anxiety” Questionnaire by B. Phillips. The study sample consisted of 2105 students from schools in the Central and Volga Federal Districts. The constructive validity of the test has been statistically proven. Confirmatory factor analysis showed satisfactory compliance of empirical data with the structure of the questionnaire. The scales correlate with each other at the average level, the directions of the connections correspond to the expected ones. The internal reliability of all scales was statistically confirmed using the Cronbach’s alpha coefficient. Differential validity has been statistically proven. The questionnaire can be recommended to teachers-psychologists to study the problems of anxiety at school.

AIM: To elucidate the profiles of commensal bacteria on the ocular surfaces of patients with varying severity of dry eye (DE).
METHODS: The single-center, prospective, case-control, observational study categorized all participants into three distinct groups: 1) control group (n=61), 2) mild DE group (n=56), and 3) moderate-to-severe DE group (n=82). Schirmer's tear secretion strips were used, and the bacterial microbiota was analyzed using 16S ribosomal ribonucleic acid gene sequencing.
RESULTS: The three groups had significant differences in alpha diversity: the control group had the highest richness (Chao1, Faith's phylogenetic diversity), the mild DE group showed the highest diversity (Shannon, Simpson), and the moderate-to-severe DE group had the lowest of the above-mentioned indices. DE severity was positively correlated with a reduction in beta diversity of the microbial community, with the moderate-to-severe DE group exhibiting the lowest beta diversity. Linear discriminant analysis effect size presented distinct dominant taxa that significantly differed between each. Furthermore, the exacerbation of DE corresponded with the enrichment of certain pathogenic bacteria, as determined by random forest analysis.
CONCLUSION: As DE severity worsens, microbial community diversity tends to decrease. DE development corresponds with changes in microbial constituents, primarily characterized by reduced microbial diversity and a more homogenous species composition.

Published: November 2023

AIM: To describe the optical coherence tomography angiography (OCTA) characteristics of exudative and non-exudative treatment-naïve pachychoroid neovasculopathy (PNV).
METHODS: Thirty-five patients with exudative treatment-naïve PNV and 13 with non-exudative treatment-naïve PNV between March 2020 and December 2021 were included. All patients underwent ophthalmologic examination, including fluorescein angiography (FA), indocyanine green angiography (ICGA), spectral-domain OCT, and OCTA. The clinical data of the patients were retrospectively analyzed.
RESULTS: The study included 51 eyes from 46 patients, of whom 33 (71.7%) were male. The central macular thickness (CMT) in the exudative PNV group was significantly higher than that in the non-exudative PNV group (383.97±132.16 µm vs 213.13±51.63 µm; P<0.001). The maximum height of flat irregular pigment epithelial detachments (FIPED) was 45.40±11.86 μm in the non-exudative PNV group, significantly lower than the 71.58±20.91 μm (P<0.001) in the exudative PNV group. The area of PNV of the non-exudative PNV group was, significantly larger than that of the exudative PNV group (1.06±0.84 mm2 vs 0.63±0.80 mm2, P=0.016). There was a significant difference in PNV morphology between the two groups (P<0.001). Multivariate logistic regression analysis found that the maximum height of FIPED (OR=1.156, 95%CI: 1.019-1.312; P=0.024) and microvascular branches (OR=69.412, 95%CI: 3.538-1361.844; P=0.005) were independent predictors of PNV activity.
CONCLUSION: The OCTA imaging finds that there are significant differences in CMT, maximum height of FIPED, PNV area, and morphology of exudative PNV and non-exudative PNV groups. OCTA can accurately identify the clinical and imaging features of exudative and non-exudative treatment-naïve PNV, and distinguish PNV activity.

AIM: To analyze the prevalence of peripapillary intra-choroidal cavitation (PICC) in eyes with gamma peripapillary atrophy (γPPA), in eyes with peripapillary staphyloma (PPS) and in those combining γPPA and PPS and to analyze border tissue discontinuity in PICC.
METHODS: This prospective cross-sectional non interventional study included highly myopic eyes. Non-highly myopic eyes were used as control. Radial and linear scans centered on the optic nerve head were performed using spectral-domain optical coherence tomography. Variables were analyzed along the twelve hourly optical coherence tomography sections in both eyes of each subject.
RESULTS: A total of 667 eyes of 334 subjects were included: 229 (34.3%) highly myopic eyes and 438 (65.7%) non highly myopic eyes. The mean age of the highly myopic group was 48.99±17.81y. PICC was found in a total of 40 eyes and in 13.2% (29/220) of highly myopic eyes. PICC was found in 10.4% (40/386) of eyes with γPPA, in 20.5% (40/195) of eyes with PPS and in 22.7% (40/176) of those combining γPPA and PPS. All the eyes with PICC showed the co-existence of γPPA and PPS whereas none of the eyes presenting only one of these entities exhibited PICC. A border tissue discontinuity in the γPPA area was found in all eyes with PICC.
CONCLUSION: We confirm the presence of a border tissue discontinuity in the γPPA area of all eyes with PICC. These findings suggest the involvement of mechanical factors in the pathogenesis of PICC which may contribute to PICC-related visual field defects.
MÉTODO HÍBRIDO DE FRONTERAS NO REFLECTIVAS EN LÍMITES DE MODELOS SÍSMICOS

Published: November 2023

Para modelar la propagación de ondas en un medio, se utilizan fronteras artificiales para eliminar las reflexiones en los límites del dominio computacional finito. Diversos enfoques han logrado atenuar parcialmente estas señales no deseadas. La implementación de capas perfectamente acopladas (PML) elimina estas reflexiones en un medio continuo. El uso de métodos de diferencias finitas o elementos finitos requiere un modelo discretizado espacialmente, lo que da lugar a remanentes de tales reflexiones. Reducir el tamaño de la rejilla resulta en la atenuación de las reflexiones pero aumenta el consumo de recursos computacionales. En este trabajo se presentan los resultados al introducir una función de atenuación a la solución mediante PML en la zona de absorción, logrando una atenuación satisfactoria sin aumentar significativamente el uso de recursos computacionales. Las simulaciones se realizaron utilizando diferencias finitas, tanto en modelos simples de capas planas con buzamiento como en modelos con una mayor complejidad estructural.

Emergiram duas categorias: Interdisciplinaridade: uma utopia? e (Multi) (Inter) (Trans) disciplinaridade: conceito. Apontou-se os desafios à interdisciplinaridade relativos a aspectos pessoais, grupais, estruturais e conceituais, o que faz com que ela seja caracterizada como uma utopia. Também, observou-se incoerência entre discurso e prática profissional, visto por equívoco conceitual entre interdisciplinaridade e multidisciplinaridade. Conclusão: aponta-se a necessidade de ações de educação permanente para favorecer o esclarecimento de dúvidas conceituais e práticas referentes à organização, construção e desenvolvimento de uma equipe nos moldes interdisciplinares.
Information Preparedness and Community Engagement for El Niño in the Eastern and Southern Africa Region
Authors: Rohan Hana
Published: November 2023

El Niño can be viewed as a multi-hazard event, and considerations for information needs cut across different populations and risks, including direct weather-related hazards, reduced agricultural production, greater food insecurity and malnutrition, increased transmission of infectious diseases and effects on health care access. Long- and short-term hazard warning communications may need to contain different calls to action, and there are likely to be different levels of urgency to those calls. This key considerations brief describes the implications of El Niño in the East and Southern Africa Region (ESAR) for Risk Communication and Community Engagement (RCCE) initiatives, based on previous comparable weather events. Lessons learnt are predominantly taken from the literature on communicating forecast and weather information, but have implications for multi-hazard RCCE response. Some lessons learnt are also taken from beyond East and Southern Africa, but considered within the anticipated El Niño effects in ESAR specifically. The first section of the brief is on information needs, the second section is on ensuring and building trust in information, and the final section is on communications and community engagement strategies. The brief was commissioned by the Collective Service as a resource for organisations working on RCCE related to El Niño in ESAR.

The goal of teaching and learning in the class is to make the students understand the material. The goal can be reached if the learners are highly motivated to learn and the lecturer can deliver the material. Moreover, in English phonology, to make the students more understand and interested in learning it, the lecturers can use some media, like videos on YouTube, to support their teaching. So the students can comprehend English phonology entirely. The study is mainly intended to find the use of native speakers' videos in encouraging the students' understanding of learning English phonology and students' responses to those strategies. The design of the study was descriptive. The data were collected through classroom observation and a questionnaire. The research respondents were the 36 students of the English teaching-learning program. The result showed that using native speakers' videos on YouTube can encourage students' understanding of English phonology. So, using native speakers' videos in teaching English phonology is well-recommended.

Authors: KONU Meltem Merve
Published: November 2023

Çalışmanın amacı, ortaokul Türkçe ders kitaplarındaki sözcük öğretimi etkinliklerini sıklık ve çeşitlilik açısından dil biliminin alt ve uygulamalı alanları çerçevesinde sistemli biçimde değerlendirerek eklenebilecek etkinlik türlerine yönelik öneriler sunmaktır. Çalışmada temel nitel araştırma deseni kullanılmıştır. Veriler doküman incelemesi ile ortaokul Türkçe ders kitaplarından elde edilmiştir. Bu doğrultuda 5.sınıfta 147, 6. Sınıfta 121, 7. sınıfta 142, 8. sınıfta 151 etkinlik (toplam 561 etkinlik) 12 dil bilimi alanına göre oluşturulan 54 farklı değerlendirme ölçütü açısından betimsel analiz tekniğiyle çözümlenmiştir. Çalışmanın geçerliğini ve güvenilirliğini sağlamak amacıyla inceleme iki farklı alan uzmanı tarafından da yapılmıştır. Bulgular üç farklı sonuç açısından değerlendirilmiştir: 12 dil bilimi alanı için 5. sınıfta 10, 6. sınıfta 9, 7. sınıfta 10, 8. sınıfta 8 farklı alandan yararlanıldığı; 54 farklı değerlendirme ölçütü açısından 5. sınıfta 18, 6. sınıfta 17, 7. sınıfta 16, 8. sınıfta 14; sözcük öğretimi içerikli etkinliklerin genel sıklığı ise 5. sınıfta 147, 6. sınıfta 121, 7. sınıfta 142, 8. sınıfta 151 olarak tespit edilmiştir. Kitaplardaki toplam etkinlik sayılarına göre sözcük öğretimi etkinlikleri için % 40- 53 arasında değişen bir oran söz konusudur. Dil biliminin 12 alanı açısından yararlanılan alan sayısı 8-10 arasındadır. 54 farklı değerlendirme ölçütü için ise sonucun 14-18 arasında olmasının ölçüt sayısının yarısı bile olmaması nedeniyle etkinliklerde çeşitliğin artırılarak farklı türde sözcük öğretimi etkinliklerinin de ders kitaplarına dâhil edilebileceği düşünülmektedir.
Investigation of novel ceramic materials (Al2O3 and SSiC) for high-pressure pumps’ delivery sections
Authors: Idzior Marek , Karpiuk Wojciech , Smolec Rafal
Published: November 2023

In this paper, a comparative analysis of structural materials used in the construction of high-pressure pumps’ delivery sections was carried out. The focus was on a comparison of the ceramic materials such as corundum (alumina, Al2O3) and silicon carbide (solid-state sintered) – SSiC with bearing alloy steel 100 Cr6, that is the most common material used to make piston and cylinders of the delivery section of common rail injection pumps. Simulations performed using finite element method have proven that ceramic materials have a number of advantages and could therefore be an interesting substitute for materials traditionally used in this area.
What can social workers learn about community development in the wake of the COVID-19 pandemic?
Authors: Mackle Danielle , O'Brien Fergal
Published: November 2023

The COVID-19 pandemic has created an opportunity to re-explore community development in the context of social work. In Northern Ireland (NI), community development is a central component of a social work student’s practice placement, whereby students must evidence how they have met this. Over time, we have witnessed the reduction of community development to leaflet making (based on feedback from Practice Teachers across NI using a mentimetre tool). This article addresses what social work students and practitioners can take forward in terms of community development in the wake of the COVID-19 pandemic. The article will use NI as a case example to draw on COVID-19 inspired community development case studies, taking examples from practice, including work conducted online, and the role, practice, and efficacy of virtual community development during a time of physical distancing. We conclude that social work teaching and learning globally need to strengthen student understanding of community development beyond leaflet production to a coherent set of knowledge, skills, and values

The estimation of barite resources (BaSO4) as well as resources of metals (Au, Ag, Cu, Zn, Pb) was made with the help of modern precision research methods at the Talmovskie Peskitailing dump (Salair Ridge). Processed ores at the tailings dump are characterized by a large vertical heterogeneity; primary (substantially non-oxidized) and oxidized sands are distinguished with Bacontents of 39 and 35 %, respectively. Grain-size classes lower 0.25 mm are the most productive from the point of view of barite. Such occurrence forms and typomorphic characteristics as color, morphology, grain size distribution, mineral paragenesis and inclusions are described for barite and metals. Geoelectric measurements have shown a horizontally-layered structure of the tailing dump, where the values of ER (21–50 Ohm•m) corresponds to the friable oxidized matter of low humidity (up to the depth of 70 cm), 0.1–20 Ohm•m – to primary, substantially non-oxidized matter. According to the results of electrical resistivity tomography, the volumes of both media were determined (48,000 and 53,000 cu), that, in comparison with the data on the concentrations of Ba, Pb, Cu, Zn, Au, Ag in them, made it possible to calculate the resources of metals within the studied area and, in some approximation, in the entire storage.

In recent decades, more and more researchers and practitioners have expressed their interest in sustainable development and sustainability. Since it was introduced in 1987, the concept of sustainable development has been treated by the United Nations in various ways, which are of reference not only to countries but also to companies. However, a clear understanding of how organizations should address sustainability is still missing, despite all efforts to encourage companies to improve their triple balance sheet. Today, sustainability reporting has become a common practice among the world’s leading companies as individuals are increasingly taking environmental, social, and governance (ESG) factors into account in their investment decisions. Nevertheless, adapting to a business environment where responsible investment becomes the rule poses several challenges to organizations. Even though transparency and non-financial reporting are gradually gaining ground and receiving more and more attention in Europe, there is still considerable emphasis on financial reporting in the eastern part of the continent. Consequently, in this paper, the authors are looking to identify how several selected companies listed on BVB (Bucharest Stock Exchange) (from different industries) take into account ESG values. They achieved their goal by conducting a content benchmark analysis, which emphasized the similarities and differences between the reports of the companies included in the analysis, issued over different periods. Last but not least, there were highlighted the standards and the non-financial reporting tools considered in the analysis carried out.
