Published: May 2021

Abstract
Background: The diagnosis of gastrointestinal nematode (GIN) infections in ruminants is routinely based on morphological/morphometric analysis of parasite specimens recovered by coprological methods and followed by larval culture techniques. Such an approach is laborious, time-consuming, requires a skilled expert and moreover suffers from certain limitations. Molecular tools are able to overcome the majority of these issues, providing accurate identification of nematode species and, therefore, may be valuable in sustainable parasite control strategies.Methods: Two multiplex real-time PCR assays for specific detection of six main GIN species, including an internal amplification control to avoid false negative results, were designed targeting SSU rRNA and COI genetic markers, as well as established ITS1/2 sequences. The assays were optimized for analysis of DNA extracted directly from sheep faeces and verified for Haemonchus contortus, Teladorsagia circumcincta, Trichostrongylus colubriformis, Nematodirus battus, Chabertia ovina, and Ashworthius sidemi. Semi‑quantitative evaluation of infection intensity was enabled using a plasmid construct and a dilution series of sheep faeces with a known number of nematode eggs. Assays were tested on 44 individually collected faecal samples from three farms and results were compared to those from faecal egg counts (FEC) using the Concentration McMaster technique, and larval cultures (LC).Results: Multiplex real-time PCR assays showed great specificity to target nematodes. During the analysis of faecal samples, the assays proved to have higher sensitivity in strongylid-type egg detection over FEC by revealing 3 false negative samples, while showing moderate agreement in evaluation of infection intensity. The multiplex assays further clarified GIN species identification compared to LC, which had confused determination of Teladorsagia spp. for Trichostrongylus spp.Conclusions: Our multiplex assays proved to be a rapid and accurate approach enabling simultaneous and reliable GIN species identification from faeces and semi-quantitative estimation of the number of eggs present. This approach increases diagnostic value and may add a high degree of precision to evaluation of anthelmintic efficacy, where it is important to identify species surviving after treatment.
Oscillatory persistent currents in quantum rings
Authors: Vasilchenko Alexander A. 
Published: May 2021

Abstract
The density functional theory is used to study persistent currents in two-dimensional quantum rings containing several electrons. We find a series of magic numbers for the total angular momentum of electrons in the strong magnetic field and show that changes in the angular momentum of electrons lead to persistent current oscillations. We suggest an empirical expression for the period of persistent current in quantum rings and examine the effect of Coulomb interaction on the properties of persistent currents.
Evidence-based Environmental and Public Health Practices to Respond to the COVID-19 Crisis

Abstract
Background: Given the unprecedented novel nature and scale of coronavirus and the global nature of this public health crisis, which upended many public/environmental research norms almost overnight. However, with further waves of the virus expected and more pandemics anticipated. The COVID-19 pandemic of 2020 opened our eyes to the ever-changing conditions and uncertainty that exists in our world today, particularly with regards to environmental and public health practices disruption.Objectives: This paper explores environmental and public health evidence-based practices toward Responding to Covid-19.Methods: A literature review tried to do a deep dive by using a variety of search engines including Research Gate, Google Scholar, Summon, PubMed, Scopus, Hinari, Dimension, CAB Abstract, OARE Abstract, Academia, Mendeley, SSRN search strategy to retrieve research publications, “grey literature” and expert working group reports.Results: To achieve improved population health, more widespread adoption of evidence-based strategies is recommended, particularly in this uncertain time. As only together can evidence-informed decision-making (EIDM) can become a reality which include effective policies and practices, transparency and accountability of decisions, and equity outcomes; these are all more relevant in resource-constrained contexts, such as Nigeria. Effective and ethical EIDM though requires the production and use of high-quality evidence that are timely, relevant and structured. One way to do so is through co-production. Co-production (or co-creation or co-design) of environmental/public health evidence considered as a key tool for addressing complex global crises such as the high risk of severe COVID-19 in different nations.Discussion: A significant evidence-based component of environmental/public health (EBEPH) consist of decisions making based on best accessible, evidence that is peer-reviewed; using data as well as systematic information systems; community engagement in policy making; conducting sound evaluation; do a thorough program-planning frameworks; as well as disseminating what is being learned. As researchers, scientists, statisticians, journal editors, practitioners, as well as decision makers strive to improve population health, having a natural tendency toward scrutinizing the scientific literature aimed at novel research findings serving as the foundation for intervention as well as prevention programs. The main inspiration behind conducting research ought to be toward stimulating and collaborating appropriately on public/environmental health action. Hence, there is need for a “Plan B” of effective behavioural, environmental, social and systems interventions (BESSI) to reduce transmission.

Published: May 2021

Abstract
Four new Keratinophyton species (Ascomycota, Pezizomycotina, Onygenales), K. gollerae, K. lemmensii, K. straussii and K. wagneri, isolated from soil samples originating from Europe (Austria, Italy and Slovakia) are described and illustrated. The new taxa are well supported by phylogenetic analysis of the internal transcribed spacer region (ITS) region, the combined data analysis of ITS and the nuclear large subunit (LSU) rDNA, and their phenotype. Based on ITS phylogeny, within the Keratinophyton clade, K. lemmensii is clustered with K. durum, K. hubeiense, K. submersum and K. siglerae, while K. gollerae, K. straussii and K. wagneri are resolved in a separate terminal cluster. All four new species can be well distinguished from other asexual morphs in the genus Keratinophyton based on phenotypical characteristics alone. Ten new combinations are proposed for Chrysosporium asexual morphs which are resolved in the monophyletic Keratinophyton clade.
Multi-objectives robust optimization based on Grey-Taguchi method for the electric vehicle frame collision
Authors: Xie Jipeng , Yang Guolai , Zhao Zhendong , Ni Jianhua 
Published: May 2021

The proportion of electric vehicles in vehicle manufacturing is increasing, but with the endurance mileage of the battery improved, the collision safety problem of electric vehicles is becoming more prominent. To solve a multi-objective robust design problem with discrete variables for vehicle collision design, we propose the Grey-Taguchi robust optimization method. The Grey-Taguchi method transforms the multi-objective functions into a single grey relation grade sequence instead of the signal-noises ratio used in Taguchi and selects the optimal combination of design variables predicted by the minimum design of experimental and the analysis of means. For the vehicle crashworthiness problem, the Grey-Taguchi method can converge to the Pareto front with several iterations. The mass of frame, maximum lateral intrusion, and peak deceleration after the optimization are decreased 14.5 %, 32.3 %, and 17.8 %, respectively. The Grey-Taguchi robust optimization method can not only enhance the robustness of the optimization design but also improve the lightweight design performance and crashworthiness. The proposed method is considered promising for complex engineering design problems with multi-objectives and discrete design variables.
Challenges of post-war policy reforms in Lebanon's water sector – lessons learned
Authors: Gharios Georges , Farajalla Nadim , El Hajj Rana 
Published: May 2021

Abstract
Lebanon has not been able to properly develop and benefit from its water sources. A confessional system of governance has hindered development of the sector. Laws and regulations have been developed erratically with many superseding others without the superseded laws being erased from the registry. This created a chaotic regulatory and legal environment with overlapping jurisdictions and no clear accountability mechanisms. The period before the onset of the civil war in 1975 witnessed significant progress of both infrastructure and laws and regulations related to the management of the water sector. The civil war destroyed the water sector infrastructure and emptied all regulatory control of the resources. The period of reconstruction between 1990 and 1999 witnessed the promulgation of ambitious reconstruction plans for the water sector with funding reliant on borrowing from local and external debtors. Post 1999, government reforms started creeping into the system but were often donor driven and still suffered from the same mistakes of laws overlain on top of existing laws without erasing the older material. Critically, the management of the sector is not inclusive and the beneficiaries of water services are often not heard and ignored.

Abstract
The textile industry is one of the main generators of industrial effluent due to the large volumes of water containing a wide variety of pollutants, including dyes. Thus, the present study aimed to remove the Disperse Blue 56 dye present in synthetic textile effluent using ionic flocculation through surfactant flocs produced from animal/vegetable fat, assessing the system at different surfactant concentrations and temperatures. The process kinetics, adsorption mechanism and equilibrium were evaluated. The results show that the kinetics was better described by the Elovich model when compared to pseudo-first order and pseudo-second order models, indicating that chemical adsorption occurs during the process. The study of the adsorption mechanism obtained lower outer layer diffusivities than their intra-particle counterparts, demonstrating that the dye transport to the surfactant floc is controlled through the outer layer. The Langmuir isotherm was suitable for equilibrium data and the separation factor calculated showed that the isotherm is classified as favorable. Dye removal efficiency reached 87% after 360 minutes of contact between the effluent and the surfactant flocs, indicating that ionic flocculation is an efficient alternative in the treatment of textile effluent containing disperse dye.
Development of LaxCa1-xMnO3 materials for Bezaktiv Blue removal in aqueous media
Authors: Nascimento É. V. , Garrido Pedrosa A. M. , Souza M. J. B. 
Published: May 2021

Abstract
In this work, mixed oxides of LaxCa1-xMnO3 perovskite type (x = 0, 0.5 and 1.0) were synthesized through modified proteic method using collagen and calcination process at 700 °C/2 h in order to remove the commercial textile dye Bezaktiv Blue S-MAX from water. Oxides were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), N2 physisorption, scanning electron microscopy (SEM) and point of zero charge (PZC) techniques while the dye only by the first two techniques. The XRD showed that perovskite monophase was obtained for x = 0.5 and 1.0. However, for x = 0, the low crystalline perovskite phase was obtained in the midst of precursor oxides. FTIR showed the adsorption process did not damage the adsorbents structure. The successful obtained materials have meso and macroporous with slit or cavity shape, rough surface and particles with varying sizes. The pseudo-second-order model was the one that best fit the kinetic data. The process must occur through electrostatic surface interactions between the adsorbent surface and the dye molecule. For the equilibrium study, Langmuir isotherm is the most suitable when using LaMnO3 adsorbent, while Freundlich isotherm was better suited when used the other two materials. The adsorbents were termally regenerated and reused five times. The best performance was exhibited by LaMnO3.

Published: May 2021

A imposição de isolamento social decorrente da pandemia da Covid-19 desencadeou a suspensão das aulas presenciais em toda rede pública e privada de ensino no Brasil. Com isso, docentes de instituições privadas de cursos superiores presenciais de turismo se depararam com a realidade de lecionar longe da convencional sala de aula, tendo que transpor o planejamento pedagógico pautado no ensino presencial para o ensino remoto. Perante essa conjuntura, o objetivo geral desta pesquisa foi investigar as experiências desses docentes devido à implementação do ensino remoto. Quanto aos procedimentos metodológicos, adotou-se a abordagem qualitativa, tendo como instrumento de coleta de dados entrevistas semiestruturadas online com docentes de cursos presenciais de bacharelado em turismo de instituições privadas no estado do Rio de Janeiro, no período de 21 a 28 de maio de 2020. A sistematização e análise de dados ocorreu baseada na pesquisa de Estrada-Villa (2014), concomitantemente ao uso dos pressupostos de análise categorial-temática de Bardin (2011). Como resultados, identificou-se oito categorias: (1) atitude e interesse; (2) características dos estudantes; (3) política da Instituição de Ensino Superior; (4) ferramentas e recursos tecnológicos; (5) treinamento; (6) capacitação docente; (7) ambiente de trabalho e trabalho de reprodução social; (8) condições físicas e psicológicas. Logo, o ensino remoto não apenas expôs o problema da desigualdade ao acesso à tecnologia digital, mas também vários outros problemas que atingem tanto docentes quanto discentes: ambiência para estudos; saúde mental-psicológica; e falta de políticas públicas direcionadas à primeira infância para auxiliar mães e pais docentes.

Published: May 2021

Penelitian ini bertujuan agar 1) masyarakat mengenal Angguk Kipas 2) agar angguk kipas menjadi lebih menarik 3) agar Tari Kipas asri bisa menjadi bahan ajar di sekolah 4) agar Tari kipas asri mampu menjadi magnet generasi muda untuk berkarya. Metode penelitian yang digunakan adalah etnokoreologi, yaitu Etnokoreologi itu sendiri merupakan istilah yang masih sangat muda. Di Amerika istilah ini identik dengan dance ethnology. Sebelum ada istilah etnokoreologi, pertama-tama muncul istilah ethnochoreography atau etnokoreografi di awal tahun 1960-an. Hasil penelitian adalah Proses penciptaan karya tari Kipas Asri tentu mengalami berbagai permasalahan dan kendala yang dihadapi. Terkadang sesuatu yang telah direncanakan faktanya berbeda ketika berada di lapangan, salah satu contoh seperti kesepakatan jadwal latihan dengan pemusik, mengatur jadwal dengan pemusik tidak semudah yang direncanakan karena pemusik memiliki jadwal lain yang sama dengan jadwal latihan karya tari Kipas Aari. Banyak hal yang dialami dalam realisasi proses penciptaan yang justru lebih banyak mengajarkan tentang proses kerja kelompok dalam mencipta sebuah karya tari seperti mengatur emosi ketika para penari atau pemusik sedang bercanda gurau, atau terlambat saat datang latihan. Kata Kunci: Tari kipas asri, penciptaan, etnokoerologi KIPAS ARI DANCEThis study aims to 1) let people know Angguk Kipas 2) make Angguk Kipas more attractive 3) make Asri Fan Dance be one of the teaching material in school 4) make Asri Fan Dance become a magnet for young generations to perform. The research method used is ethochoreology, which it itself is a new term. In America this term is synonymous with dance ethnology. Before the term ethnocoreology, the term ethnochoreography or ethnocoreography first appeared in the early 1960s. The results of the study show that there are obstacles in the creation process of Kipas Asri dance. Sometimes, something that has been planned turned to be different when in the field, one of the examples is the agreement on a training schedule with musicians, arranging a schedule with musicians is not as easy as it seemed because musicians have other schedules that are similar to the Kipas Aari dance practice’s schedule. Many things are experienced in the realization of the creation process which actually teaches more about group work in creating a dance work such as controlling emotions when dancers or musicians are joking or late when coming to practice.

DETERMINANTES ECONÓMICOS - FINANCIEROS DE LA RENTABILIDAD SOBRE EL PATRIMONIO EN LAS CAJAS MUNICIPALES DE AHORRO Y CRÉDITO DEL PERÚ, PERÍODO 2010 – 2014
Authors: Aparicio Ballena Jorge Alberto 
Published: May 2021

Las Cajas Municipales de Ahorro y Crédito (CMAC) han crecido en el período 2010–2014, pero no a la velocidad de años anteriores, por ejemplo, sus activos totales y sus créditos directos, crecieron en dicho periodo en 162% y 159% respectivamente. Sin embargo, este importante crecimiento se viene contrarrestando con una tendencia negativa de los principales indicadores económicos y financieros de las CMACs. En el período analizado, las rentabilidades se incrementaron en el año 2011 en la mayoría de las cajas, sin embargo en el 2012 y 2013 disminuyeron notoriamente. Llevando a establecer el objetivo de describir los principales determinantes económicos – financieros de la rentabilidad que afectan el retorno del patrimonio en las CMACs. La investigación se realizó a las 11 cajas municipales existentes, siendo esta, de tipo correlacional porque trató de establecer la relación entre los determinantes económicos – financieros de la rentabilidad de las CMACs del Perú con el patrimonio de las mismas. De acuerdo a los resultados obtenidos, y a la significancia estadística de los parámetros a través del test de ANOVA se ha logrado comprobar la hipótesis general. Por lo que se concluye que el ratio de capital global, ratio de morosidad, ratio de eficiencia, y ratio de endeudamiento, son estadísticamente significativos para explicar la rentabilidad sobre el patrimonio de las Cajas Municipales de Ahorro y Crédito del Perú, en el período 2010 – 2014.Palabras Clave: Indicadores, Rentabilidad, Patrimonio, Determinantes Economicos-Financieros.
VIVENCIAS DE PÉRDIDA AMBIGUA ANTE LA DESAPARICIÓN FORZADA DE UN INTEGRANTE DE FAMILIA

Published: May 2021

El objetivo de este texto es analizar el impacto emocional y social de la desaparición forzada de una persona, en los integrantes de su familia y sus implicaciones en la dinámica familiar. Se empleó la metodología cualitativa, desde el enfoque fenomenológico, con base en la técnica de la entrevista profunda; el estudio se realizó en Morelia Michoacán, México, con la participación de una familia (madre, padre, 3 hermanas e hija del desaparecido). Los resultados obtenidos a partir del análisis de los discursos de los participantes, permitieron establecer cinco categorías: afrontamiento del duelo, distintos tipos del duelo vivido, malestares orgánicos, estrategias familiares de recuperación, afrontamiento de la falta de apoyo legal por parte de la familia. Se encontró que la familia atraviesa por una pérdida ambigua, la cual ocasiona confusión, estrés, y que a menudo atormenta su vida cotidiana. Resulta de gran relevancia comprender que con frecuencia los familiares tienen la esperanza de que el desaparecido regrese y que, al no contar con la certeza de su situación actual, se da pie a la vivencia de la pérdida ambigua, por tanto, se dificulta el procesamiento del duelo y la reestructuración del sentido de vida. En el caso de estudio, la desaparición impactó en la dinámica familiar, ya que fortalecieron su vínculo con la intención de aminorar su dolor.
