Popular justice in Sri Lanka: A sociocultural artifact
Authors: Welikala Sepalika
Published: January 2021

Conceptualizing law broadly as ideology and practice relating to normative orders, prescriptive frameworks and markers of difference embedded in social, cultural, economic and political processes, this paper examines popular justice in Sri Lanka as a sociocultural artifact that is constructed or molded by the particular context in which it exists. As discussed in the paper, popular justice in contemporary Sri Lanka functions as state-sponsored, informal community-led forums of dispute resolution known formerly as Conciliation Boards and later as Mediation Boards. By analyzing the shifting and changing ideology, rhetoric and practice of popular justice within these forums, as represented in legislative debates and other documents, an attempt is made to theorize popular justice as a social construct that is reflective of the society in which it operates. From the initial establishment of Conciliation Boards as a law reform project to the subsequent re-enactment in the form of Mediation Boards and the many amendments to the law that governs them, the rhetoric and practice of popular justice evolved in tandem with the changing social, economic and political landscape. The assemblage of ideologies and practices surrounding these dispute settlement forums therefore suggests the need to understand popular justice as constitutive of particular social conditions of a sociocultural artifact, which can also be applied to similar laws and law-like processes as well.
Youth and Youthâ€™s Religiosity in Sri Lanka
Authors: De Silva Premakumara
Published: January 2021

Sri Lankan youth and youth religiosity has indicated that youth as being hopeless and revolutionary, but this study shows that it is not always through when one closely looks at the everyday life of youth in a more ethnographical sense. The ethnographical accounts that researcher has presented; indicates the way young people behave, contest, and negotiate in the context of a sacred site as well as how youth assimilate and transform their religious heritage quite different even though they proclaim their affinity with religion. Youth pilgrims come to Sri Pada to worship and to ask for help. No doubt many youths do go to Sri PÄda for more than worshipping the sacred footprint and the deity, or than seeking favour from its divine powers for their worries and frustration. This paper explained their â€˜sacredâ€™ intentions are combined with the achievement of maximum pleasure. Both the pleasurable and the religious dimensions of these specific pilgrim groups were explored through the accounts of personal experiences (e.g., through case studies and memories of pilgrims). These youth pilgrims visit Sri Pada with different motivations and intentions, both â€˜religiousâ€™ and â€˜secularâ€™. The interconnecting of both sacred and secular aspects of Sri Lankan youth have not been considered when they were identified as a sociological category and this paper is suggested to overcome that conceptual inadequacy of youth research in Sri Lanka.

Authors: Figueira Mariane , Calegario Cristina Lelis Leal , Luchesi Paulo Henrique Moretti
Published: January 2021

Essa pesquisa teve como objetivo principal analisar, por meio de um estudo de casos múltiplos, como o relacionamento entre matriz e subsidiária e como a atuação da própria matriz podem influenciar no desenvolvimento de inovações na subsidiária. Quatro empresas brasileiras de setores diferentes que foram adquiridas nos últimos dez anos por empresas multinacionais, provenientes da Alemanha e da França, se tornando subsidiárias, foram selecionadas como unidades-caso. A coleta de dados se deu por meio de pesquisa bibliográfica e documental e entrevistas em profundidade com gestores e proprietários das subsidiárias pesquisadas. Os dados foram analisados por meio de análise de conteúdo temática. Os resultados mostraram que os processos de aquisição que inseriram as empresas brasileiras nas redes das multinacionais se traduziram em benefícios para os dois lados, principalmente para as subsidiárias que após os processos de incorporação tiveram algum tipo de inovação desencadeado.

Published: January 2021

Os Resíduos Sólidos Urbanos (RSU) se configuram como uma problemática tanto no Brasil como em outras partes do mundo e isso exige que se pense em meios de como amenizar seus impactos negativos. Assim, o objetivo deste artigo consiste em realizar um comparativo financeiro e ambiental entre os modais ferroviário e rodoviário no transporte de resíduos sólidos urbanos via simulação baseada na Dinâmica de Sistemas. Para a modelagem adotou-se à metodologia proposta por Law (2015) e, logo após, a definição de todas as equações e suas relações o modelo foi simulado considerando um horizonte de tempo de onze anos. Os resultados revelam que, visto de uma perspectiva financeira, há uma grande diferença existente entre os modais rodoviário e ferroviário no transporte dos RSU. Portanto, demonstra a importância da valorização das ferrovias, e também, apresenta-se como outra opção aos gestores para o transporte do lixo gerado na região estudada.

Satisfação no trabalho: Estudo longitudinal em uma Organização Pública de Ensino Superior
Authors: La Falce Jefferson Lopes , Martins Aline De Paula , De Muylder Cristiana Fernandes , Pardini Daniel Jardim
Published: January 2021

Objetivo: O objetivo foi analisar a evolução do nível de satisfação no trabalho dos servidores públicos de uma Instituição de Ensino Superior nos anos de 2016 e 2018, anos que tratam de mudança de carga horária na organização.Originalidade/Lacuna: Em pesquisa bibliometrica realizada na base SPELL com os termos “satisfação no trabalho”, “organização pública” e “longitudinal”, não foram encontrados estudos sobre o tema.Aspectos metodológicos: Foi realizada uma pesquisa de campo, com abordagens quantitativa e qualitativa. Os dados foram obtidos por meio de questionários utilizando a Escala da Satisfação no Trabalho (Siqueira, 2008), aplicados aos servidores públicos da organização na cidade de Belo Horizonte nos anos de 2016 e 2018. Utilizou-se ainda 6 entrevistas para entender os fatores que estariam influenciando a alteração da satisfação.Síntese dos resultados: Os dois anos de pesquisa resultaram em indiferença por parte dos funcionários públicos. Porém, em 2018 as dimensões de satisfação com o salário, com a chefia e as promoções resultaram em insatisfação, diferentemente do primeiro ano em que os funcionários se demonstraram indiferentes em todas dimensões. A maioria dos participantes alegou que a mudança de horário implementada na instituição foi o motivador da insatisfação.Principais considerações: É importante que gestores tenham uma visão da variação da satisfação de seus funcionários utilizando estudos longitudinais, visto que contribuem para reduzir os impactos de políticas de gestão que podem ocorrer devido à diminuição da satisfação dos funcionários, como diminuição da produtividade, rotatividade, absenteísmo, dentre outros.

Published: January 2021

The literature is full of works that highlight the positive effects of the application of information technology on business processes, including gains in terms of transparency, efficiency and effectiveness. However, there is a growing number of studies showing that, in parallel with technological innovation, phenomena occur that cause distress and malaise to the workers, with  studies on technostress being highlighted, that is, the difficulty of adapting to technological innovations in the work environment. However, few studies have been carried out to understand the negative effects of this technological transformation on public servants. Thus, the objective of this study is to identify the role of technostress on job satisfaction and organizational commitment in the context of the public sector. The technique of analysis of structural equations (CB-SEM) to analyze data collected with users of information technology from a Brazilian public organization. We have identified that the technostress negatively affects the satisfaction, which, in turn, positively impacts the commitment. In a complementary way, the relation between the demographic characteristics of the workers and the creators of technostress are presented in detail. As a result, several theoretical and practical implications are also discussed.

Published: January 2021

Grapevine canes are vine growing byproducts studied for their antimicrobial activities. These properties are directly connected to the stilbene content; oligomeric stilbenes being the most active. In this study, we propose a chemical process, based on oxidative coupling, using metals to increase the oligostilbene rate and the biological effectivity of cane extract against grapevine pathogens. A total of ten compounds were obtained and identified by combining LCMS and NMR spectroscopies, including four newly reported compounds: trans-oxistilbenin C, trans-oxistilbenin D, and cis- and trans-oxistilbenin E. The extract and the main stilbene formed were evaluated for their preventive effects on Plasmopara viticola and Botrytis cinerea growth. The processed extract was highly effective against both pathogens.
Citron Watermelon Potential to Improve Crop Diversification and Reduce Negative Impacts of Climate Change
Authors: Mandizvo Takudzwa , Odindo Alfred Oduor , Mashilo Jacob
Published: January 2021

Citron watermelon (Citrullus lanatus var. citroides) is an underexploited and under-researched crop species with potential to contribute to crop diversification in sub-Saharan Africa and beyond. The species is commonly cultivated in the drier parts of Southern Africa, mainly by smallholder farmers who maintain a wide range of landraces. Understanding the molecular and morpho-physiological basis for drought adaptation of Citron watermelon in these dry environments can aid in screening local germplasm, identification of suitable traits for crop improvement and improving food system resilience among smallholder farmers by adding to crop diversification. This paper reviews literature on drought adaptation of C. lanatus spp. (C3 xerophytes), using the systematic review approach. The review discusses; (i) the potential role of citron watermelon in adding to crop diversification, (ii) alternative food uses and potential by-products that can be processed from citron watermelon and (iii) the role of Sub-Saharan farmers as key actors in conserving citron watermelon germplasm and biodiversity. Finally, the review provides a summary of significant findings and identifies critical knowledge gaps for further research.
Where you Live Matters: A Spatial Analysis of COVID-19 Mortality
Authors: Javaheri Behzad
Published: January 2021

The COVID-19 pandemic has caused ~ 2 million fatalities. Significant progress has been made in advancing our understanding of the disease process, one of the unanswered questions, however, is the anomaly in the case/mortality ratio with Mexico as a clear example. Herein, this anomaly is explored by spatial analysis and whether mortality varies locally according to local factors. To address this, hexagonal cartogram maps (hexbin) used to spatially map COVID-19 mortality and visualise association with patient-level data on demographics and pre-existing health conditions. This was further interrogated at local Mexico City level by choropleth mapping. Our data show that the use of hexagonal cartograms is a better approach for spatial mapping of COVID-19 data in Mexico as it addresses bias in area size and population. We report sex/age-related spatial relationship with mortality amongst the Mexican states and a trend between health conditions and mortality at the state level. Within Mexico City, there is a clear south, north divide with higher mortality in the northern municipalities. Deceased patients in these northern municipalities have the highest pre-existing health conditions. Taken together, this study provides an improved presentation of COVID-19 mapping in Mexico and demonstrates spatial divergence of the mortality in Mexico.

Information, especially its automated processing, is still an important factor in improving the efficiency of any organization. Distributed information systems (IS, ISs) differ from conventional ISs in architectural and infrastructural principles, as well as in the geographic location with integration into one information cluster. One of the examples of distributed information systems is the infrastructure of the Google search engine - more than 2,000 servers, with server bases in almost every country in the world, which allows achieving a minimum delay in sending and receiving client requests. A distributed information system can have a large number of different databases, both local and remote, with which constant data synchronization is required, while maintaining a backup copy of previous data in case of failures and emergency stops. Distributed information systems are highly reliable and require multi-level protection of the cluster from unauthorized access, adherence to the principles of data synchronization, which differ from a conventional information system. Within the framework of this paper, synchronization processes are investigated using mathematical and computational tools, creating an environment for distributed information systems. It is advisable to use the results of the work to coordinate the operation of components of multi-agent systems for various purposes, transmit messages between agents, build communication protocols, and provide conditions for self-organization of multi-agent systems.

Authors:   National University of Public Service, Lentner Csaba , Molnar Petronella ,   Budapest Business School - University of Applied Sciences, Nagy Vitez ,   Corvinus University of Budapest
Published: January 2021

Introduction. The increasing measurability of performances in the public sector in the countries of the post-soviet region, including Hungary, has come to the limelight in recent decades. Accrual accounting, adopted in Hungary in 2014 on the recommendation of the European Union, provides decision-makers with reliable information and simultaneously improves transparency in spending. Purpose and Methodology. This study focuses on the impacts and synergies of the parallel comprehensive reforms in the public finances and the adoption of the accrual accounting system. We conducted an empirical research among 2425 budgetary organisations (during June 2018 - January 2019) and analysed the correlation between the variables with cross-table analysis. Our survey covered 19.1 per cent of all the budget organisations in Hungary. Thus, thanks to the sample size the survey results analysis gives a comprehensive view of the entire country based on the real feedback regarding the implementation of the new practices. Results. In the course of the survey, the organisations were asked to describe how they were affected by the transition to the new accounting system, how they had prepared for the statutory changes and compliance, what additional tasks the adoption of the new system required of them, and how they evaluated the impacts of the application of accrual accounting after five years. The inquiry focussed on the impact this new accrual-based accounting system had on the business management of the given organisation and thus the efficient use of public funds. The results confirm that the historical background and the peculiarities of managing public funds in a country should also be taken into account during the adoption of reforms along with thorough preparation. Our research also sheds light on the fact that the successful 2014 adoption of accrual accounting could achieve its full purpose in an environment ensured by comprehensive public finance reforms and laws adopted after 2010. In other words, the precondition of enforcing the new rules of accrual accounting applied in the public sector included the reinforcement of budgetary regulation and control procedures. Conclusion. The study reports more favourable public sector procedures, proves that the adoption of accrual accounting has been justified and that the higher focus on performance and efficiency achieved through accrual accounting is important.
Features and trends of the Chernobyl tourism development
Authors:   CEO, The Association of Hospitality of Ukraine, Romanova Anna
Published: January 2021

The author defines Chernobyl tourism as a visit to the exclusion zone, which was formed as a result of a large-scale technological disaster, i.e., an explosion at the Chernobyl nuclear power station in 1986, for educational, scientific, business, recreational and other tourism purposes. The complexity of Chernobyl tourism is proved and schematically presented. The main types of tourism which can be promoted in the Chernobyl Zone (ChZ) such as cultural, cinema, active, scientific, conference, dark, sentimental, adventure, extreme, industrial, business, event, diplomatic and ecotourism had been analyzed. Four stages of the development of Chernobyl tourism are disclosed: 1) illegal visits to the exclusion zone (starting from the late 1980s); 2) official visits (starting from the late 1990s); 3) emergence of Chernobyl tourism companies (starting from the first decade of the 2000s); 4) mass tourism (starting from the second decade of the 2000s). The statistics of visiting the ChZ for the last five years had been analyzed. The number of foreigners visiting ChZ was compared with the total number of foreigners visiting Ukraine. The results of the marketing research of the profile of 1000 random visitors to the ChZ, conducted in November 2019, are presented. The formula of the economic contribution of Chernobyl tourism to the development of the tourism sector of Ukraine and the national economy as a whole has been derived. As a result of generalization of statistical data, as well as the results of marketing research, a number of features of Chernobyl tourism was formulated and analyzed: uniqueness of this tourism product; phasing of development; tours organization; availability of various types of tourism; dominance of foreign tourists; relatively high cost of the product; narrow segmentation of the product; purposefulness of the tours; the game, television and film industry influence; short trips duration; three-level self-organization of Chernobyl tourism; an increase in the number of illegal tourists; the lack of developed tourism infrastructure; the high interest of foreign investors; the lack of a systematic scientific and strategic approach. The recommendations for authorities and representatives of Chernobyl tourism promotion companies were formulated to increase the economic contribution of this type of tourism.
Продуктивность зоопланктона в прибрежной зоне южной части Баренцева моря в весенний период
Authors: Дворецкий В. Г. , Дворецкий А. Г.
Published: January 2021

Представлены результаты анализа состояния зоопланктонного сообщества в южной части Баренцева моря. Пробы отобраны в ходе экспедиции НИС «Дальние Зеленцы» в мае 2016 г. Гидрологические условия были типичными для мурманской прибрежной водной массы в этот сезон. Всего обнаружено 47 таксонов зоопланктона. Их количество колебалась по станциям от 18 до 29. Копеподы были доминирующей группой в зоопланктоне. Наиболее часто встречались Calanus finmarchicus, Metridia longa, Metridia lucens, Microcalanus spp., Oithona atlantica, Oithona similis, Pseudocalanus spp., науплии и яйца копепод, а также кладоцеры Evadne nordmanni, личинки иглокожих, полихет, щетинкочелюстные Parasagitta elegans, ювенильные стадии эвфаузиид рода Thysanoessa. В составе популяций массовых видов копепод Pseudocalanus spp. и Oithona similis преобладали младшие возрастные группы, что свидетельствовало о продолжающемся их размножении. Суммарная численность зоопланктона варьировала от 748 до 6576 экз.·м−3, составляя в среднем 3012. Общая биомасса колебалась от 17 до 157 мг сухой массы·м−3, средняя величина равнялась 83. Полученные величи́ны сопоставимы с данными июля 2008 г. и превышают показатели августа 2007 г., что авторы связали с разными сезонами отбора проб и с различающимися гидрологическими условиями. Суточная продукция зоопланктона колебалась в диапазоне 0,49–4,04 мг сухой массы·м−3 при средней величине (2,17 ± 0,17), что примерно в 2 раза выше, чем средние показатели для мурманских прибрежных вод в летний период. Вероятно, эти различия связаны с более высокой концентрацией фитопланктона в весеннее время. Суммарная величина запаса зоопланктона в исследуемой акватории (25,8 тыс. км²) оценена в 425 тыс. т сухой массы. Кластерный анализ выявил наличие четырёх групп станций, которые различались соотношением Calanus finmarchicus, Copepoda nauplii, Oithona similis, личинок иглокожих и аппендикулярий Fritillaria borealis. Пространственную изменчивость численности зоопланктона определяли местоположение станций (широта, долгота, глубина), а также температура придонного слоя и средняя солёность вод на станции.
Генотипирование черноморских трематод семейства Opecoelidae по митохондриальным маркерам
Authors: Катохин А. В. , Корнийчук Ю. М.
Published: January 2021

Opecoelidae Ozaki, 1925 (Trematoda: Opecoeloidea) — ведущее по числу видов и родов семейство трематод в Чёрном море. Мариты наиболее распространённых видов черноморских опецелидных трематод подробно описаны морфологически, однако сведения о структуре их геномов отрывочны, а данные о митохондриальных геномах отсутствуют полностью. Цель исследования — получить первые сведения о строении участков митохондриального генома представителей наиболее распространённых в Чёрном море в современный период родов трематод семейства Opecoelidae для последующего уточнения их таксономического статуса. Филогенетические отношения внутри анализируемой части этого семейства реконструированы на основе данных, полученных нами, и соответствующих данных из GenBank с помощью алгоритма Maximum Likelihood и модели нуклеотидных замен HKY. Для укоренения филогенетического дерева использованы соответствующие последовательности Brachycladium goliath (Brachycladioidea: Brachycladiidae). Поскольку последовательности CO1 — стандартного и наиболее популярного митохондриального маркера — для исследуемых родов опецелид до сих пор не были известны, нами на основе известных соответствующих последовательностей Xiphidiata разработаны праймеры для амплификации фрагмента CO1, чтобы впервые провести соответствующий филогенетический анализ. Впервые определены и депонированы в GenBank нуклеотидные последовательности фрагментов митохондриальных генов CO1 и 16S черноморских трематод Cainocreadium flesi Korniychuk & Gaevskaya, 2000, Gaevskajatrema perezi (Mathias, 1926) Gibson & Bray, 1982 и Helicometra fasciata (Rudolphi, 1819) Odhner, 1902 от разных видов дефинитивных хозяев — рыб. У C. flesi не выявлено специфичных к окончательным хозяевам — рыбам линий по структуре фрагмента митохондриального гена CO1, однако отмечено высокое CO1-нуклеотидное разнообразие. У марит черноморских H. fasciata определена приуроченная к зеленушкам-руленам Symphodus tinca CO1-гаплогруппа, статус которой требует дальнейшего выяснения; необходимы экологические и генетические исследования предполагаемого видового комплекса H. fasciata из разных акваторий. При анализе последовательностей фрагмента митохондриального гена 16S рРНК гостальных генетических линий у H. fasciata выделить не удалось. У черноморских G. perezi не обнаружено значительных различий по фрагменту 16S между трематодами из окончательных хозяев разных видов, однако внутривидовое 16S-нуклеотидное разнообразие оказалось высоким.

Актуальность мониторинга содержания тяжёлых металлов в водах Атлантического сектора Антарктики определяется необходимостью современной оценки качества водной среды для принятия ответственных решений по сохранению морских живых ресурсов в этом уникальном регионе Мирового океана. Цель проводимых исследований — получить новые данные об уровнях и пространственном распределении концентрации микроэлементов, преимущественно тяжёлых металлов, в поверхностной воде. Отбор проб поверхностной морской воды производили в антарктической экспедиции 79-го рейса НИС «Академик Мстислав Келдыш» на 21 станции в районе проливов Дрейка, Брансфилда, Антарктика, а также в морях Уэдделла и Скотия. Экстракцию и концентрирование растворённой формы 13 микроэлементов (Be, Se, Sb, Tl, V, Pb, Cd, Cu, Zn, Ni, Mo, Co и Fe) осуществляли с помощью диэтилдитиокарбамата натрия и четырёххлористого углерода (CCl4). Измерение элементов проводили масс-спектрометрическим методом. Только для Mo на девяти станциях, расположенных в проливах Дрейка и Брансфилда, в северном районе моря Уэдделла, а также возле южного побережья острова Огненная Земля, отмечали превышение его концентрации в морской воде в 1,2–2,8 раза по отношению к ПДК микроэлементов в воде рыбохозяйственных объектов РФ (ПДКРХ). Согласно международным нормативно-правовым актам, таким как «Голландские листы», зарегистрированы единичные случаи превышения MPC (maximum permissible concentration — ПДК при краткосрочном воздействии) для Cd и Zn, а также превышение TV (target value — контрольные уровни при хроническом воздействии) для Cu, Pb, Cd, Zn, Se и Co на нескольких станциях. Исследования показали, что, несмотря на ограниченный режим антропогенной нагрузки в этом регионе Южного океана, в морской воде отдельных районов Атлантического сектора Антарктики в современный период зафиксированы повышенные концентрации некоторых микроэлементов, включая тяжёлые металлы. Необходимо дальнейшее изучение источников поступления и особенностей распределения микроэлементов в морских водах Атлантической части Антарктики для объяснения происходящих процессов, а также для принятия мер по рациональному управлению и экологически приемлемому природопользованию в Антарктическом регионе.

Sustainable Food Reserved Garden Program (SFRG) was designed to increase the potential of backyard to provide sustainable cheap food. This study aimed to analyze the factors affecting household’s vegetables consumption in the area of SFRG program. The research was conducted in Samarinda and Bontang City in 2018, involving 60 respondents who have implemented the program. Respondents were divided into three strata according yard size, which are stratum 1 (narrow), stratum 2 (medium) and stratum 3 (extensive). Data was collected through interviews using a structured questionnaire and focus group discussions with managers of the program. Afterwards, the data were analyzed descriptively. The result showed that the variations of plants types tend to be uniform among the three strata such as eggplant, peppers, tomatoes, cabbage, kale, leeks and spinach. In terms of the arrangement, narrow stratum was dominated by “vertikultur”, medium stratum by polybag and extensive stratum by seedbeds.

Influence of the Different Carbon and Nitrogen Sources on the Production of Biodiesel by Oleaginous Fungi Aspergillus terreus, Aspergillus fumigatus
Authors: Shafiq Shatha Ali , Abdulkareem Afrah Fahad , Shafi Farha A. Ali
Published: January 2021

In the present study, the growth and total lipid contents of two oleaginous fungal isolates Aspergillus terreus, Aspergillus fumigatus were compared in different nitrogen and organic carbon sources.  Artificially the fungi were cultured on media consisting of various mono- or di- or polysaccharides and  peptone or yeast extract as elementary sources for carbon and nitrogen, respectively. Media containing sucrose /yeast extract or glucose/ yeast extract were the most effective for lipid production from fungal, during  two weeks  incubation period, the highest biomass of dry weight was (19.6 , 18.8) g / L , (25.8 , 30.5) g /L  and  lipid yield (1, 0.97 )g/L, (0.65, 0.65) g/ L for two isolates Aspergillus terreus and Aspergillus fumigatus  respectively then followed maltose/ yeast extract then  starch / yeast extract .Analysis of fatty acid produced by two fungal isolates  using Gas Chromatography  showed the existence of a wide range of fatty acids, these fatty acids were together saturated and unsaturated. The results revealed that the unevenness in the fatty acids composition mainly depends on the type of carbon and nitrogen sources. The existence of saturated and mono saturated fatty acids in A.fumigatus, A. terreus prove that they are  good candidate for biodiesel production.

The synthesis of new substituted cobalt Phthalocyanine (CoPc) was carried out using starting materials Naphthalene-1,4,5, tetracarbonic acid dianhydride (NDI) employing dry process method. Metal oxides (MO) alloy of (60%Ni3O4 40%-Co3O4 ) have been functionalized with multiwall carbon nanotubes (F-MWCNTs) to produce (F-MWCNTs/MO) nanocomposite (E2) and mixed with  CoPc to yield (F-MWCNT/CoPc/MO) (E3). These composites were investigated using different analytical and spectrophotometric methods such as 1H-NMR (0-18 ppm), FTIR spectroscopy in the range of (400-4000cm-1), powder X-rays diffraction (PXRD, 2θ o = 10-80), Raman spectroscopy (0-4000 cm-1), and UV-Visible spectrophotometry (0-800 nm). Then the activity of these materials was investigated as a gas sensing of (Ammonia, Methanol and Acetone). For each case, 0.2 mg/.mL of the prepared Copc, Copc/MWCNT, Copc/MWCNTs–MO was dispersed in 1m of ammonia, methanol and acetone at 298K. The surface morphology of the prepared materials was heterogeneous.

Authors: Elsaid Mohammad , Ali Mahmoud , Shaer Ayham
Published: January 2021

In this paper, a theoretical study of the energy spectra and the heat capacity of one electron quantum dot with Gaussian Confinement in an external magnetic field are presented. Using the exact diagonalization technique, the Hamiltonian of the Gaussian Quantum Dot (GQD) including the electron spin is solved. All the elements in the energy matrix are found in closed form. The eigenenergies of the electron were displayed as a function of magnetic field, Gaussian confinement potential depth and quantum dot size. Explanations to the behavior of the quantum dot heat capacity curve, as a function of external applied magnetic field and temperature, are presented.

Introduction: The increase in the number of participants of Ultimate Frisbee suggest the necessity to improve the knowledge about this sport and its demands. Thus, the aim of this study was to quantify and compare the external loads imposed upon players during official Ultimate Frisbee matches according to sex. Material and methods: Twelve male and female players participated in four official Ultimate Frisbee matches. Players were divided according to sex (8 males and 4 females). Results: The average duration of matches was 62.3 ± 13.8 min, during which the players were active for 34.9 ± 11.4 min. External loads (i.e., total distance covered, distance covered at different speeds, accelerations and decelerations) encountered by Ultimate Frisbee players were compared between sexes (males vs females). Male players registered greater external loads (p < 0.05 large-moderate), especially performing high-intensity actions (distance at high intensity, distance at very-high speeds, and medium-high accelerations and decelerations) than female players. Conclusions: Coaching and performance staff should consider the sex of each player when developing training programmes and tactical strategies to optimise player performance during Ultimate Frisbee matches.
