Published: September 2024

Aim. This article investigates how Virtual Collaborative Learning environments can be integrated into university courses and what their implications are so that they promote more meaningful learning. Two pilot courses, which were part of the Erasmus+ CBHE Valeu-X project, Business Communication and Image Processing offered by "Aleksander Moisiu", University Durres, were part of this research. This study focuses on how the designs of VCL can help students improve problem-solving skills, confidence, and communication skills, encourage engagement and social interaction, and inspire creativity.
Methods. Qualitative research design was used in this study with data collected and analysed manually by the researcher. The participatory observation was used in the implementation of two pilot courses – Image Processing and Business Communication using Teams as their online learning platform. The data were gathered through the close observation of the dynamics in Virtual Collaborative Learning environments focusing on the roles and interactions between the participants.
Results. This research proves that assigning roles to students during online learning group activity helps them collaborate effectively. At the same time, tutors were preferred as they are referred to as helpers among students. Teams were able to study together and socialize with one another by assigning specific tasks to the team members and by using the appropriate tools.
Conclusion. Virtual collaborative learning ought to be taught in university courses, particularly in Europe's emerging nations. It involves assigning tasks to group members to foster productivity and cooperation. According to the study's participants, e-tutors play a critical role in the educational process.
Conceptualisation and operationalisation of minorities in international law: Past experiences and new avenues
Authors: Nagy Noémi , Vizi Balázs 
Published: September 2024

AbstractDespite decades of scholarly effort, there is still no universally accepted definition of the concept of minorities or the criteria for minority membership. Beyond its theoretical importance, the lack of a definition also has practical significance, as it may easily lead to the abuse of minority rights. In this paper, we offer a brief historical overview of the various definitional attempts in international law, including those enshrined in legal documents as well as in the practice of adjudicatory bodies. Starting from the era of the League of Nations and the case-law of the Permanent Court of International Justice, we continue by looking at major developments within the United Nations (with special attention to the practice of the Human Rights Committee) as well as the Council of Europe (and the approach of the Advisory Committee of the Framework Convention for National Minorities). Our aim is to explore the trajectory from old to recent conceptual endeavours, where the major dividing line is drawn between the relatively narrow notion of minorities (covering only autochthonous or traditional groups) as opposed to a more inclusive view (including also immigrants and, potentially, visitors under the minority protection mechanisms).
Evolução planetária e as assimétricas flechas do espaço-tempo na auto-organização do Antropoceno
Authors: Camargo Luis Henrique de 
Published: September 2024

Este artigo objetiva verificar a relação da sociedade com a natureza, e os seus fluxos energéticos termodinâmicos, como elemento evolutivo, gerando totalização e sendo analisados pela(s) flecha(s) do espaço-tempo. Este artigo verificará também, como este processo influencia na formação do Antropoceno. Neste sentido, serão aplicados os princípios nascidos após o advento da mecânica quântica, à análise espaço-temporal da physis (que integra sociedade-natureza). O artigo verifica, também, como cada forma-conteúdo, de forma singular, contribui energeticamente para o desenvolvimento da sua flecha do espaço-tempo. Assim, será verificado também como o processo produtivo atual associa-se, em geral, ao rompimento dos estados de homeostase, no balanço energético do processo de troca entre energia e matéria, e como o antigo padrão de relativa estabilidade, que caracterizava o Holoceno, vem sendo substituído pela desordem, que está na base do surgimento do Antropoceno.

Published: September 2024

A proposta deste artigo é a de analisar o perfil socioeconômico dos migrantes do Sul Global em Porto Alegre, capital do estado do Rio Grande do Sul, Brasil. A partir de uma pesquisa exploratória, com a utilização de dados secundários sobre os migrantes internacionais no Brasil, coletados via Sistema de Registro Nacional Migratório (SISMIGRA) e as informações contidas na Relação Anual de Informações Sociais (RAIS), buscamos: (i) identificar as principais nacionalidades dos migrantes do Sul-Global; (ii) evidenciar o gênero e raça/cor dos trabalhadores migrantes; (iii) analisar a escolaridade, principais profissões e remuneração média em salários mínimos (SM) dos migrantes. Com base nos dados coletados observamos que Porto Alegre tornou-se território de destino para migrantes do Sul Global – em sua maioria, homens, pretos e/ou pardos, provenientes do Haiti e da Venezuela, chegados ao Brasil em busca de trabalho. A sua escolaridade, em geral, é superior à do nacional, contudo atua em profissões de baixa remuneração, especialmente no setor de serviços gerais. No caso das mulheres, a inserção destas no mercado de trabalho formal é ainda menor em relação aos homens. A migração Sul-Sul está envolta em elementos que se articulam em torno das estruturas sociais e econômicas. No caso dos migrantes do Sul Global em Porto Alegre, o olhar mais atento sobre raça e gênero, revela que as tradicionais discriminações laborais recebidas por brasileiros desses grupos, também são observadas nos migrantes internacionais.

Published: September 2024

A Thornwaldt's cyst develops in the nasopharynx, which is the region where the throat and nasal passageways converge, extending from the back of the nasal tube to above the soft palate. A painful throat, obstruction of the eustachian tube, and pus with an unpleasant taste and odour might result from an infection of the cyst. Here in our study, we report a case of a 27-year-old male presented with symptoms of nasal obstruction and voice change for the past 1 year. On zero-degree endoscopic examination, a nasopharyngeal mass was seen arising from the roof of the nasopharynx without bony erosion of skull base. Further based on his radiological investigations, heterogeneous hyperintense lesion in T1/T2 weighted images of size 5×5 mm noted in nasopharynx most likely to be the Thornwaldt’s cyst. Thus, the surgical removal of the nasopharyngeal mass has been performed through a transoral and trans nasal endoscopic technique with no remnants at the surgical site. The histopathological findings revealed respiratory-type epithelium with underlying lymphoid tissue confirming Thornwald’s cyst as diagnosis. The patient was discharged with no complications and have been periodically advised for a follow-up. The differential diagnosis should include a meningocele or meningo-encephalocele. Various therapeutic approaches, including endoscopic, transoral, or trans palatal surgical interventions, can be used for treatment of symptomatic cysts.

Analysis of the influence of local electrodeposition conditions on the accuracy of electrochemical 3D-printing
Authors: Vasyliev Georgii , Kotyk Mykhailo 
Published: September 2024

Problem. Additive manufacturing of metal parts by local electrodeposition is a new promising area with several unique features. The use of electrolysis makes it possible to manufacture metal parts at room temperature with high accuracy and low energy consumption. The accuracy and speed of electrochemical 3D printing are inversely related, and therefore it is important to find optimal electrodeposition conditions at maximum speed without degrading accuracy.
The aim of the study. The purpose of this work was to analyse the influence of electrodeposition parameters (electrode distance, electrical conductivity and electrolyte polarization) on the accuracy of metal deposit formation in a computer model and to conduct experimental verification of optimal conditions for electroforming a real object from copper sulphate electrolyte.
Methodology of implementation. To achieve the goals of the study, computer simulation of the electrochemical deposition process in the COMSOL Multiphysics software and electrochemical measurements of the characteristics of copper sulphate electrolytes were used.
Research results. Computer simulation established optimal conditions: the distance between the edge of the capillary and the surface on which deposition occurs is not more than 0.5 mm, the electrolyte in which the inverse slope of the cathode polarization curve is not lower than 2000 mA/(V×cm2) and the electrical conductivity is not higher than 0.02 S/сm. The influence of the electrolyte composition on the inverse polarization of the cathode process and its electrical conductivity was investigated. The optimal composition of the electrolyte was selected, containing 200 g/L CuSO4, 60 g/L H2SO4, 0.2 g/L KCl and RUBIN T-200 additive. In the selected electrolyte, the value of the inverse slope of the cathode polarization curve is 2120 mA/(V×cm2). Verification of the process of local electrodeposition in the selected electrolyte during the electroformation of a cylindrical object with a diameter of 4 mm and a height of 100 μm was carried out. It was determined that no more than 5 % of metal was deposited outside the capillary of the working electrode.
Conclusions. The results of the work can be used to create an electrochemical 3D printing system. Further research should be aimed at approbation of the obtained parameters of local electrodeposition in an installation that simulates the operation of a 3D printer and establish the accuracy and speed of printing of a three-dimensional object.
Key words: additive manufacturing, electrical conductivity, electrolyte composition, polarization, local electrodeposition.

Field evaluation of germplasm lines of extra-long staple cotton (Gossypium barbadense) for Tobacco Streak Virus (TSV) resistance based on symptoms expression
Authors: P Valarmathi , Mari Amutha 
Published: September 2024

Abstract

Background
The necrosis disease caused by Tobacco streak virus (TSV) is highly destructive. Conventional management practices for TSV includes cultural methods such as crop rotation, maintaining field sanitation, rouging of infected plants, intercropping with non-host crops of short duration, eliminating weed hosts like Parthenium and insecticide application to control vectors. However, the most efficient and convenient approach to combat this devastating disease is to cultivate resistant varieties.
Results
TSV distribution in the germplasm of ELS cotton, Gossypium barbadense, appears to be significant. In a consecutive two-season screening at ICAR-Central Institute for Cotton Research (CICR), Regional Station, Coimbatore, total of three hundred G. barbadense germplasm lines were evaluated for natural occurrence of TSV. Among them, fourteen germplasm lines were categorized as Resistant (R), twenty-two as Moderately Resistant (MR), one hundred and sixty-eight as Moderately Susceptible (MS), and ninety-four as Susceptible (S) lines.
Conclusion
The identified fourteen resistant germplasm lines of G. barbadense can be valuable resources in breeding programs as donor parents to develop TSV-resistant lines. Utilizing these lines in breeding efforts can contribute to the development of resistant varieties against TSV.

Abstract

Rabigh area is one of the most promising areas in the Southwestern province in Saudi Arabia. Forthcoming governmental developments and vigorous activities are planned to be located in and around Rabigh area. Pollution rates have increased significantly in Rabigh Governorate recently due to industrial development in the region, as well as the presence of landfills designated for hazardous industrial waste, and unqualified sewage landfills. In addition, marine environment pollution is caused by direct industrial discharge into the sea in the coastal area of ​​Rabigh. As a result, there is an urgent need for many studies that must clarify the pollution hotspots in the city, as well as determine the nature of pollutants on site. In the present study, samples of soil, groundwater, seawater and sediment were collected and analyzed to measure the concentration of pollutants in soil and water. Also, air quality measurements were made in the study area. Arc GIS software was used to analyze the data and identify pollution hotspots in the study area. The environmental land-water quality map (Fig. 15) assesses five classes with varying degrees (very low, low, moderate, high, and very high) of environmental quality zones. The environmental quality map (Fig. 15) shows that the study area is in a high environmental quality zone, but most of the areas surrounding it are in a very high to moderate environmental quality zone Except the southern part of the study area (Landfill area) it is in the moderate quality to low quality zone. The low-quality zones in the seawater among the study area, especially the southern part of the study area because of the increasing development therein.

Published: September 2024

Abstract

The ubiquity of microplastics (MPs) in various foodstuffs and beverages has raised substantial public health concerns. This study aimed to develop a novel method for counting and sizing MP particles in bottled water using Nile Red staining combined with Direct Microscopic Count (DMC). A filtration process with a 0.25 µm mixed cellulose ester (MCE) membrane filter was employed, followed by dissolving the filter with acetone to avoid background interference, and staining MPs with Nile Red. MPs were counted and measured using a fluorescent microscope, and their polymer nature was confirmed via Raman Confocal Spectroscopy. This study tested 60 plastic bottled water samples from 20 brands produced in Iran for MP contamination. The concentration of MPs varied between 0 and 608 particles per mL, with an average of 109.5 particles per mL. The number of MP particles with size < 10, 11–100, 101–200 and > 200 µm was 74.3, 34.6, 1.5 and 0.9 per mL, respectively. Afterward, by exposing particles stained with Nile Red to laser using Raman Confocal spectroscopy it was found that 94% of the particles were PET, 5.7% were PE, and only 0.3% were PP.
