The Effects of Deposition Time on Phase and Structure of FeCoNi Films
Authors: Mulyadi Muhamad , Afrizal
Published: June 2022

This study aims to determine the effects of deposition time on the phase and structure of FeCoNi. FeCoNi was prepared by electrodeposition method at room temperature. X-ray diffraction measurement shows the formation of a single phase of FeCoNi at 5 and 10 minutes of deposition, while at 20, 35, and 50 minutes, a new phase was formed, namely CoNi. The obtained FeCoNi and CoNi show a crystal plane at 2θ = 44.05° (111); 51.33° (002); and 75.59° (022) in all different deposition times, indicating the face centered cubic crystal structure. The effect of deposition time on the chemicals composition shows an anomalous co-deposition because Fe has a larger ratio than Co and Ni. The deposition rate and the value of current efficiency were found to be optimum at FeCoNi synthesized for 20 minutes, namely 0.00214 mg/cm2s and 97.00%.

Published: June 2022

Problema: A demanda em saúde mental na Atenção Primária à Saúde (APS) é alta, e a capacitação das equipes para a detecção e o tratamento desses pacientes é fundamental, sendo o matriciamento, modelo de cuidado colaborativo desenvolvido no contexto brasileiro, uma ferramenta importante para a efetividade do cuidado em saúde mental na APS. Em março de 2020, com o isolamento social consequente à pandemia pelo novo coronavírus, houve necessidade de reorganização dos serviços. O objetivo deste artigo é descrever a experiência de telematriciamento e reorganização do apoio matricial em saúde mental em unidade da APS do município do Rio de Janeiro, nos primeiros meses de pandemia. Método: O Centro Municipal de Saúde Heitor Beltrão localiza-se na Zona Norte do Rio de Janeiro. Nos anos de 2017 a 2019, o matriciamento ocorreu por meio de consultas conjuntas, discussão de casos e grupo de psicotrópicos. No início da pandemia, o trabalho foi reorganizado em duas frentes: teleconsultas conjuntas síncronas e organização da lista de usuários com transtornos mentais. Resultados: Foram realizadas 50 teleconsultas conjuntas no período de 12 semanas, com média de 4,16 consultas/semana, sendo os diagnósticos mais frequentes transtornos depressivos e ansiosos seguidos de transtornos de personalidade e por uso de substâncias. O novo formato permitiu a manutenção do acesso de usuários da saúde mental ao serviço, a absorção de novos casos, a melhoria de acesso a usuários do grupo de risco para infecção por coronavírus e a continuidade do processo formativo em saúde com aquisição de novas competências e modernização do trabalho. As principais limitações foram a falta de equipamentos disponíveis e a dificuldade de acesso à internet. Conclusão: Esta experiência, desenvolvida em razão da pandemia de COVID-19, descreve os desafios e benefícios da utilização do telematriciamento e da criação da lista de usuários da saúde mental. Poderá auxiliar profissionais e gestores de outros serviços a desenvolver adaptações mais adequadas às realidades locais.

Published: June 2022

Objective: The objective of this study was to perform genome (genome wide association studies [GWAS]) and chromosome (CWAS) wide association analyses to identify single nucleotide polymorphisms (SNPs) associated with growth traits in registered Simmental and Simbrah cattle.Methods: The phenotypes were deregressed BLUP EBVs for birth weight, weaning weight direct, weaning weight maternal, and yearling weight. The genotyping was performed with the GGP Bovine 150k chip. After the quality control analysis, 105,129 autosomal SNP from 967 animals (473 Simmental and 494 Simbrah) were used to carry out genotype association tests. The two association analyses were performed per breed and using combined information of the two breeds. The SNP associated with growth traits were mapped to their corresponding genes at 100 kb on either side.Results: A difference in magnitude of posterior probabilities was found across breeds between genome and chromosome wide association analyses. A total of 110, 143, and 302 SNP were associated with GWAS and CWAS for growth traits in the Simmental-, Simbrah-and joint -data analyses, respectively. It stands out from the enrichment analysis of the pathways for RNA polymerase (POLR2G, POLR3E) and GABAergic synapse (GABRR1, GABRR3) for Simmental cattle and p53 signaling pathway (BID, SERPINB5) for Simbrah cattle.Conclusion: Only 6,265% of the markers associated with growth traits were found using CWAS and GWAS. The associated markers using the CWAS analysis, which were not associated using the GWAS, represents information that due to the model and priors was not associated with the traits.
The Relationship Between Corporate Social Responsibility and Corporate Reputation in Serbia
Authors: Berber Nemanja , Aleksić Marko , Slavić Agneš , Strugar Jelača Maja
Published: June 2022

Corporate social responsibility (CSR) is a concept that is based on the idea of a balance between economic, social, and environmental goals of companies. In contemporary business, companies need to be responsible not just to their shareholders, but to broader stakeholders, where employees, customers, investors, suppliers, local community, and natural environment are mostly affected. Also, CSR is seen as a concept that can enhance different financial and market performances, where corporate reputation is gaining more and more attention. Corporate reputation is seen as one of the most important companies’ assets, and it has a great influence on business success. Based on the stakeholder theory and resource-based theory, the authors of this paper investigated both concepts to increase the body of knowledge and provide some practical implications for companies. The paper aims to investigate the relationship between CSR and corporate reputation. The problem of the research is defining of a relationship between CSR and corporate reputation in companies in Serbia, and between specific dimensions of CSR and corporate reputation. The methodology used in the research obtained the analysis of available literature and the empirical analysis of the data on CSR and reputation. The sample was created from 73 large private processing companies in the Republic of Serbia. The authors used PLS-SEM method to investigate the proposed relations, i.e., that CSR has a positive relation with corporate reputation. This methodology was for the first time conducted in the business environment in Serbia, which will enhance the possibility of comparison with the results from other countries. The results pointed that CSR, as a higher-order construct, has a positive relation with corporate reputation, like all dimensions of CSR (responsibility to employees, customers, local community, environment, suppliers). At the end, the authors proposed theoretical and practical implications and limitations of the research.
Breast Tuberculosis: A Report of Two Cases
Authors: Kundan Meghraj , Aswin Puthangot , Tyagi Garima , Ghosh Mainak
Published: June 2022

Introduction: Breast Tuberculosis is relatively uncommon in the modern era. However, it is necessary to understand how to manage this disease since most patients require medical management, despite presenting as a lump. Case Presentation: Both patients were young females presented with lump breasts. Bilateral breast ultrasound with axilla was suggestive of infective aetiology. Fine needle aspiration cytology (FNAC) revealed ZN stain positive acid-fast bacilli. Both patients were started on anti tubercular treatment. One patient had complete resolution of the lump; however, another patient developed an abscess drained via percutaneous aspiration. Subsequently, the dissolution of the lump was observed. Conclusions: The diagnosis of breast tuberculosis is challenging and involves constant vigilance, detailed clinical history, examination, and supporting investigations, including chest X-ray, breast ultrasound with axilla, CT thorax, FNAC, and blood investigations such as erythrocyte sedimentation rate and Mantoux test. After diagnosis, treatment with antitubercular drugs should be started and regularly followed up. Inappropriate diagnosis and treatment can result in complications such as the non-resolution of lump and/or abscess.
The cognitive dimension among university students in the area of sexual and reproductive health with an emphasis on the issue of delayed/late pregnancy and parenthood
Authors: Hřivnová Michaela , Slaná Jitka , Sofková Tereza , Cichá Martina , Marciánová Vladislava
Published: June 2022

Background: The shift in women’s fertility and birth rate to the higher age is characterized as the most significant feature of reproductive behaviour over the past decades in the Czech Republic (and in other developed countries). The trend of the so-called delayed or late pregnancy/motherhood/parenthood is determined by polyfactorial influences with possible risk impacts on the biomedical and psychosocial aspects of the health of mothers, fathers, children and society as such. In 2020, the following project was implemented: 50/2020/PPZ/OKD In Time – responsible, erudite, planned and prepared parenthood – The shaping and development of health literacy in the area of reproductive health among young adults (university students). The project was supported by the Ministry of Health of the Czech Republic and the Faculty of Education, Palacký University Olomouc. The outcomes of the project are of both educational and research nature. Method(s): The Research on the cognitive and affective dimensions of young adults in the area of early pregnancy/parenthood involving a sample of 844 student respondents from 14 universities in the Czech Republic evaluated the level of knowledge of health literacy with an emphasis on the general area of sexual and reproductive health as well as the specific area of possible risks associated with delayed/late pregnancy/parenthood. The research also focused on the personality and attitude dimensions of young adults in the context of delayed and late pregnancy. Results: In a specific area of sexual and reproductive health, the level of knowledge was problematic, sometimes even insufficient. An alarming fact is the complete lack of knowledge concerning the probability of conception during a single ovulation cycle of a young woman (18–30 years). Surprisingly, the correct answer was identified by less than 2% of female university students. The complete set of results of the research is published in the monograph In Time: The cognitive and affective dimensions of young adults in relation to pregnancy and parenthood. Conclusions: The unfavourable level of health literacy concerning early pregnancy/parenthood may have a negative effect on the affective and behavioural dimension of young adults and support the 63 manifestations of possible bio-psycho-social risks and complications resulting from the trends of shifting motherhood/parenthood to higher age bands. It is thus necessary to educate the young generation by means of adequate didactic procedures in order for them to be able to make informed decisions about whether and when to have a child.
Probabilistic thinking is the name of the game: Integrating test and confidence intervals to plan sample sizes
Authors: Luh Wei-Ming
Published: June 2022

Having high statistical power and good estimated precision are essential to statistical practice; however, this integrative consideration on sample size planning remains limited in the literature, especially for two-group mean comparisons with unequal/unknown variances and unequal sampling costs. Furthermore, due to the neglect or misuse of employing confidence intervals, the present study aims to illuminate the probabilistic thinking by finding optimal allocations of sample sizes such that researchers can claim that the null hypothesis is rejected, the desired confidence-interval width of mean difference is achieved, and/or the true difference is encompassed in the interval. Cost effectiveness was also considered to find the optimal sample size. The simulation showed that the proposed approach can maintain the desired probability level for the conditional/unconditional probabilities of events and has good coverage rates in terms of confidence intervals. This study provides an important opportunity to advance the understanding of sample size planning and confidence intervals as well. Three R Shiny apps are provided for easy application in the Supplementary Materials.

Authors: Arrufat-Martin Sandro , Rubira-García Rainer , Gomes-Franco e Silva Flávia , Venet-Gutiérrez Jacqueline
Published: June 2022

El neuromarketing como objeto de estudio en el campo de la Comunicación está ganando cada vez más atención académica en el contexto español, sobre todo en los últimos años. En este texto analizamos la evolución de este tema de investigación en las tesis doctorales durante el período 2007-2018, justo en el momento de transición de las normativas sobre estudios de postgrado a nivel nacional. A partir de una metodología de metaanálisis, de tipología mixta, se evalúan los centros científicos de producción y los autores, las configuraciones de las líneas temáticas, los conceptos y objetivos más comunes, así como el diseño metodológico en cuanto a muestras, datos, técnicas y triangulaciones dominantes. Aunque el neuromarketing continúa teniendo una presencia residual en el campo académico, el interés epistemológico que genera sigue en aumento, en particular en ámbitos de investigación fronterizos directamente vinculados con la comunicación institucional u organizacional, la comunicación de eventos y la comunicación de marca.
Contraintes du genre et recherche de l’identité sexuelle : 'L’enfant de sable', Rebecca Jäger et Alistair Houdayer
Authors: Abumallouh Ihab
Published: June 2022

Cet article se veut une lecture du corps et de la sexualité dans deux ouvrages de Ben Jelloun, à savoir L’enfant de sable et La nuit sacrée. La sexualité de l’enfant, le corps sexué de la femme, le rôle de la mère, et finalement l’effet stabilisant de la zone d’échange biologique adulte[1]. Une synthèse envisagée du point de vue de la folie/raison basée sur le discours religieux et social. Il s’agit d’une décomposition de la construction sociale de la sexualité chez la protagoniste du diptyque de Ben Jelloun à la lumière du caractère violent que le discours religieux et social pourrait charrier. Dans une première partie, nous envisageons de situer brièvement la sexualité dans la littérature maghrébine d’expression française et son introduction dans le champ littéraire maghrébin. Nous introduisons ensuite trois dimensions du genre proposées par Rebecca Jäger, une journaliste allemande trans. En effet, nous nous servons d’un documentaire réalisé par Olaf Müller et qui a pour objet d’illustrer deux expériences de franchissement du modèle binaire de la sexualité humaine. La deuxième partie de l’article détaillera la question de la sexualité tant chez Ben Jelloun que chez sa protagoniste. La sexualité en question sera entretenue dans son rapport le plus large à la religion, la raison, et plus étroitement à la folie.

[1] Nous donnons ce terme à la zone intime qui réunit Zahra et son amant aveugle. Une parallèle à la théorie de Freud afin de rappeler ce dont l’enfant de sable a été privé.
La culture et l’identité à l’épreuve du déplacement –Pour une lecture topographique du déplacement dans 'Partir' de Tahar Ben Jelloun–
Authors: Loudiyi Mourad
Published: June 2022

Cet article vise à étudier l’expression du déplacement, dans une perspective typologique et d’examiner la portée de la typologie sur l’énonciation sémantico-lexicale de l’information spatiale. Le roman Partir de Tahar Ben Jelloun se préoccupe, entre autres, du déplacement, véritables topoï prioritaires dans l’univers diégétique. Cette spatialisation du sens du monde conduit à disséquer le cautionnement de la diégèse dans un espace donné et partant de la reproblématisation des facteurs identitaires occasionnée par le déplacement. L’immigration est à la fois pour l’écrivain comme ses protagonistes, une fatalité et un choix existentiel, évoquant aussi bien le déplacement de l’être dans l’espace que le déplacement de l’espace dans l’être. Les immigrés changent de nom, de langue, de culture et d’identité. Ce mal-être identitaire révèle les deux facettes de l’errance, à savoir les pérégrinations géographiques et les égarements de l’esprit à la quête de l’eldorado européen.
Hybridité et discours de déconstruction du mythe de Félix Houphouët-Boigny dans 'Le tyran éternel' de Patrick Grainville
Authors: N'Gatta Severin
Published: June 2022

Dans le récit Le tyran éternel du romancier français Patrick Grainville, deux énonciateurs-observateurs déploient deux discours radicalement opposés sur le mythe politico-héroïque de Félix Houphouët-Boigny. D’un côté, l’écrivain fictif Sylvanus Adé présente les « mots-fantasmes » de Yamoussoukro et de l’Albinos respectivement sur les isotopies de l’hybridation pervertie et de l’amour. De l’autre, Houphouët-Boigny présente ces mêmes notions sur les isotopies respectives de l’hybridation parfaite et de la haine. Cette opposition de perception trahit la volonté auctoriale de déconstruire le mythe de Félix Houphouët-Boigny. Trois moments caractérisent cette déconstruction : la reproduction du mythe houphouétiste, la distorsion biographique et la production d’un mythe de substitution, en l’occurrence le mythe de l’Albinos.
L’identité hybride de Fatima Daas : de l’étrangèreté à l’agentivité
Authors: David Claire
Published: June 2022

La Petite dernière de Fatima Daas fait entendre la voix d’une narratrice aux prises avec sa double culture franco-algérienne et la découverte de son homosexualité. À travers cet article, notre objectif est d’analyser la façon dont le motif de l’entre-deux – communautaire, linguistique et spatial – façonne l’identité de la narratrice. En travaillant conjointement les notions d’étrangèreté et d’hybridité, nous porterons notre attention sur la géographie personnelle de la narratrice, sur ses déplacements quotidiens autant que sur le voyage vers le pays d’origine, ainsi que sur le conflit intérieur en lien avec la religion musulmane et l’identité homosexuelle. Notre hypothèse est que le refus de choisir entre ces deux identités a priori inconciliables peut se lire comme un signe d’agentivité, voire une véritable posture éthique : dans l’écriture de Fatima Daas se dessinerait en creux une conception relationnelle de l’autonomie.
Study of the Differences in the Perception of the Use of the Principles of Corporate Social Responsibility in Micro, Small and Medium-Sized Enterprises in the V4 Countries
Authors: Gavurova Beata , Schonfeld Jaroslav , Bilan Yuriy , Dudas Tomas
Published: June 2022

The aim of the study was to examine the differences in the perception of the use of selected principles by CSR managers and owners of Micro, Small and Medium-sized Enterprises (MSMEs) in the V4 countries. The results of our research show that CSR strategies are most used by entrepreneurs and managers of MSMEs in Hungary, Poland and Slovakia. They are the least used in the Czech Republic. The sectoral comparison within the V4 countries highlighted interesting findings. When considering the moral and ethical implications of decision-making, no significant differences were found between the sectors. Differences were found in the perception of the CSR concept and its use in business. The CSR concept was mostly used in tourism and agriculture, to a lesser extent in construction, retail, manufacturing and services. Managers and entrepreneurs understand the link between CSR and gaining reputation and business opportunities and that CSR helps build a competitive advantage. The size of the company affects whether the company can be classified as CSR-oriented. Compared to medium-sized enterprises, micro-enterprises are 45% less likely and small enterprises are 33.5% less likely to be perceived as CSR-oriented. Compared to companies from Slovakia, companies in the Czech Republic are 41% less likely to be perceived as CSR-oriented. Hungarian companies are 70% more likely to be perceived as CSR-oriented compared to companies from Slovakia. Companies run by women are more inclined to apply CSR principles than men.
Modelling Complex Relationships Between Sustainable Competitiveness and Digitalization
Authors: Petkovski Ivana , Fedajev Aleksandra , Bazen Jacques
Published: June 2022

Digitalization is the core component of future development in the 4.0 industrial era. It represents a powerful mechanism for enhancing the sustainable competitiveness of economies worldwide. Diverse triggering effects shape future digitalization trends. Thus, the main research goal in this study is to use sustainable competitiveness pillars (such as social, economic, environmental and energy) to evaluate international digitalization development. The proposed empirical model generates comprehensive knowledge of the sustainable competitiveness-digitalization nexus. For that purpose, a nonlinear regression has been applied on gathered annual data that consist of 33 European countries, ranging from 2010 to 2016. The dataset has been deployed using Bernoulli’s binominal distribution to derive training and testing samples and the entire analysis has been adjusted in that context. The empirical findings of artificial neural networks (ANN) suggest strong effects of the economic and energy use indicators on the digitalization progress. Nonlinear regression and ANN model summary report valuable results with a high degree of coefficient of determination (R2>0.9 for all models). Research findings state that the digitalization process is multidimensional and cannot be evaluated as an isolated phenomenon without incorporating other relevant factors that emerge in the environment. Indicators report the consumption of electrical energy in industry and households and GDP per capita to achieve the strongest effect.
Competitiveness of Germany and the Labour Market: A Migration Perspective
Authors: Privara Andrej
Published: June 2022

The current paper contributes to the existing literature on migration by explaining the emigration pattern from Denmark, Finland and Sweden to Germany. We have tried to discover the reason why people migrate from high-income European Union (EU) member states to Germany, which for a long time has hosted the highest number of migrants when compared to other EU member states. We have employed gravity models using fixed effects and ordinary least squares estimation for 1998 – 2019. Our results have indicated that Germany, compared to other EU member states, is more competitive in terms of its labour market efficiency. Germany is an attractive destination for migrants from Denmark, Finland and Sweden in terms of its employment rate, wages and effective government support of its labour force programmes. The current research provides insights into enhancing German competitiveness in terms of labour market factors, which is important for both the migrant and native populations. The results show that if wisely managed, the labour market attracts the labour force, which can address critical social issues Europe is currently facing. In particular, competition issues for high-skilled workers, an aging population, and a low birth rate. The study indicates that the long-term attractiveness of Germany for migrants is based on the efficient participation of the government in labour management-related decisions.
Involvement of Polyamines in Physiological Reactions of Herbicide-treated Wheat Seedlings Subjected to Drought and Waterlogging Stress

Published: June 2022

Polyamines are plant growth regulators, which take part in plant growth and development, as well as in the physiological responses to diverse biotic and abiotic stresses. Drought and waterlogging are environmental stress factors that disturb normal plant growth. In our study, we determined the content of polyamines spermine, spermidine, and putrescine in young wheat seedlings (Triticum aestivum L., cv. Sadovo-1) pretreated with herbicide Serrate® (Syngenta) and subjected for 7 days to drought or waterlogging. We found that when applied alone the herbicide caused some decrease in polyamine levels but it was not substantial as compared to drought and waterlogging stresses. Obvious reduction of polyamine content was caused by both stress factors when applied alone or in combination with the herbicide. The decrease was more significant in drought-stressed seedlings than in waterlogged. When plants were transferred to normal irrigation regime the polyamine concentrations in drought-stressed plants tended to increase. The waterlogging stress continued to reduce polyamine content even during the recovery period. These data correlate with the growth parameters (fresh weight, height of shoots) indicating the involvement of polyamines in the physiological responses of herbicide-primed wheat seedlings under stress conditions.

Published: June 2022

Most of the harvested fruits and vegetables cannot be stored in natural conditions for satisfactory shelf life duration due to their perishable nature. Applications of nanotechnology to fruits and vegetables shelf life extension may overcome the shortcomings of traditional preservation technologies because nanotechnology has many unique properties. The aim of this study was to examine the effect of zinc oxide nanoparticles (ZnO NPs) synthesized from Nigella sativa extract on shelf life of cucumber and tomato. Nanoparticles were characterized by using UV-Vis spectrophotometry and particle size analyzer. Vegetables were soaked in tap water, distilled water and treated with different concentrations of ZnO NPs (0.05, 0.1, 0.2 and 0.5 g/100 mL). The effect of ZnO NPs on vegetables quality factor like external appearance, weight loss measurement, carotenoid content and total phenolic content was observed. The result showed that ZnO NPs reduced weight loss, delayed disease development and maintained firmness to extend shelf life of vegetables.
Adaptor linked K63 di-ubiquitin activates Nedd4/Rsp5 E3 ligase
Authors: Zhu Lu , Zhang Qing , Cordeiro Ciro D , Banjade Sudeep , Sardana Richa , Mao Yuxin , Emr Scott D
Published: June 2022

Nedd4/Rsp5 family E3 ligases mediate numerous cellular processes, many of which require the E3 ligase to interact with PY motif containing adaptor proteins. Several arrestin-related trafficking adaptors (ARTs) of Rsp5 were self-ubiquitinated for activation, but the regulation mechanism remains elusive. Remarkably, we demonstrate that Art1, Art4, and Art5 undergo K63-linked di-ubiquitination by Rsp5. This modification enhances the plasma membrane recruitment of Rsp5 by Art1 or Art5 upon substrate induction, required for cargo protein ubiquitination. In agreement with these observations, we find that di-ubiquitin strengthens the interaction between the pombe orthologs of Rsp5 and Art1, Pub1, and Any1. Furthermore, we discover that the homologous to E6AP C-terminus (HECT) domain exosite protects the K63-linked di-ubiquitin on the adaptors from cleavage by the deubiquitination enzyme Ubp2. Together, our study uncovers a novel ubiquitination modification implemented by Rsp5 adaptor proteins, underscoring the regulatory mechanism of how adaptor proteins control the recruitment, and activity of Rsp5 for the turnover of membrane proteins.

It is of great significance to promote the quantitative research of soil science and the implementation of precision agriculture. On this basis, taking Xuwen County as the research object, this paper comprehensively analyzed the soil characteristics of cultivated land in Xuwen County and clarify the soil nutrient content and spatial distribution characteristics of cultivated land in Xuwen County, this paper comprehensively applied the methods of geostatistics, geographic information system (GIS) and fuzzy mathematics, and referred to the cultivated land quality grade standard (GB/T 33469-2016), to analyze the soil characteristics and evaluate the soil fertility of this region. The results show that the optimal interpolation model of soil pH and available phosphorus (AP) is a Gaussian model, and the optimal interpolation model of soil organic matter (SOM), available nitrogen (AN) and available potassium (AK) is a J-Bessel model. In addition, the spatial correlation of AK is weak, whereas pH, SOM, AN and AP show moderate spatial correlation. The proportion of excellent, good, average, medium and poor comprehensive fertility index are 26.00%, 32.67%, 19.33%, 19.00% and 3.00%, respectively. The overall level of soil fertility in Xuwen County is above the average, and the fertility quality presents an obvious trend of high in the South and low in the North. Areas that above average fertility are mainly distributed in Maichen Town, Qujie Town, Nanshan Town and Chengbei Town. The results can provide theoretical basis for improving the utilization rate of chemical fertilizer, fine management of cultivated land and ecological environment in this region, which can help in decision-making of precision fertilization.
Taxonomic and functional nematode diversity in Maldivian coral degradation zones: patterns across reef typologies and depths
Authors: Grassi Eleonora , Montefalcone Monica , Cesaroni Lucia , Guidi Loretta , Balsamo Maria , Semprucci Federica
Published: June 2022

The intensification of dredging and infilling activities in lagoons and on coral reefs are common practices in the Maldivian archipelago, and these activities alter the biodiversity of the bioconstructors and the functioning of the ecosystem. The alteration of environmental factors can also affect inconspicuous fauna, such as free-living nematodes. The implications of a reduction in biodiversity may transcend decreased taxonomic diversity, resulting in changes in functional diversity and redundancy; however, how the environmental conditions and human pressure affects the functionality of nematodes in Maldivian coral degradation zones (CDZs) remain poorly understood. In this paper, we examined changes in the taxonomic and functional diversity and the functional redundancy in nematode communities regarding the geographic location (atolls with various levels of human pressure), the exposure and topography of the reef (lagoon and ocean), the slope of the reef, and the depth. The functional diversity and redundancy were evaluated by considering two main biological traits of nematodes: i) the trophic strategy, and ii) the life strategy. The extremely high number of nematode genera observed in the Maldives is supported by the high complexity of the carbonate sediments. The reef exposure and depth were the most relevant environmental factors that influenced the taxonomic and functional diversity. The functional diversity, according to the trophic strategies, mirrored the taxonomic diversity because the adaptive plasticity of nematode buccal cavity structures is closely associated with the high biodiversity of the phylum. The high abundance of k-strategists in ocean reefs may indicate a higher ecological quality when compared to lagoon reefs; however, the absence of significant differences in life strategy functional diversity and functional redundancy indicates that a recovery process is underway. Analyses of nematode communities should be combined with standard investigations of reef bioconstructors during monitoring activities to assess the vulnerability of CDZ systems to future disturbances and facilitate the adoption of the most appropriate preventative actions.

El presente trabajo aborda los principales elementos que configuran el régimen concesional de los servicios públicos de telecomunicaciones, con la finalidad de poner de relieve algunos debates que tensionan la regulación chilena sobre la materia. Se entrega un breve repaso sobre el marco normativo que preside la instalación, operación y explotación de un servicio de telefonía, transmisión de datos y acceso a Internet, así como la arquitectura institucional responsable. Asimismo, se precisan las modalidades que puede adoptar el otorgamiento de este tipo de concesiones, los requisitos que debe cumplir el operador, las causales de extinción del título habilitante, así como los principales derechos y obligaciones que incumben al concesionario. A partir de algunos planteamientos formulados por los entornos académico, político-legislativo y judicial, se efectúa un balance crítico respecto al diseño actual de la política regulatoria en este sector de la economía chilena.

La incidencia de las nuevas tecnologías de la información y las comunicaciones en el ser y quehacer de la Administración Pública han impactado de lleno en las relaciones entre las personas – ciudadanos- y la Administración Pública con una rapidez, un vertigo y una velocidad nunca antes vista, que nos enfrentan como “ciudadanos del mundo” a una “nueva normalidad”, que sin lugar a dudas, significa un antes y un después, potenciadas, a nivel global, con la pandemia de la la COVID-19. Ni el Derecho en general, ni el Derecho Administrativo en particular, ni la gobernanza de las instituciones públicas ni en consecuencia sus institutos clásicos, sus pilares fundamentales, como el procedimiento administrativo tanto general como especial, los actos administrativos, la función pública, la contratación pública, así como los principios generales de nuestra disciplina ni los demás institutos clásicos de nuestra materia, son inmunes ni pueden escapar a esta “nueva normalidad” que, en forma vertiginosa y sin pedir permiso, golpea las puertas de las distintas Administraciones Públicas en su dimensión global al influjo de las nuevas tecnologías de la información y de las comunicaciones. El mundo ha cambiado. La sociedad ha cambiado. La ciudadanía ha cambiado. El Derecho Administrativo no puede estar ajeno a estos nuevos fenómenos, ya que, de lo contrario, perderá con el paso de los años, su razón de ser más

O objetivo do estudo foi avaliar a qualidade de solos destinados a disposição de resíduos sólidos por meio da Cromatografia de Pfeiffer, a fim de diagnosticar a viabilidade dessa ferramenta de baixo custo para o monitoramento ambiental. Amostras de solo foram coletadas em dois aterros sanitários (AS1 e AS2) e dois lixões (ativo - LA e desativado - LD), em três profundidades (0-20, 20-40 e 40-60 cm), nas distâncias de 1, 5 e 10 m a partir dos taludes das células dos aterros e do ponto central de disposição nos lixões. As amostras foram submetidas a análise cromatográfica. Para a avaliação qualitativa utilizou-se os parâmetros cor, integração entre zonas, radiações, atividade biológica e terminações, aos quais foram atribuídos escores. A quantificação da área das zonas (central, interna, intermediária, externa e periférica) dos cromatogramas foi efetuada com o software ImageJ. A melhor qualidade do solo foi observada em AS2 com escores médios dos parâmetros acima de 8,0, enquanto LA apresentou a pior qualidade do solo, com escores médios igual a 1,7. AS2 e AS1 apresentaram as maiores áreas dos cromatogramas totalizando aproximadamente 13.000 mm2, considerando-se as zonas central, interna, intermediária e externa. Concluiu-se que há padronização das cromas relacionadas aos locais de amostragem, ocorrendo menor qualidade nos solos em áreas de lixões, sendo detectável via cromatografia de Pfeiffer a perda da qualidade edáfica em virtude da forma de disposição de resíduos. A aplicação desta técnica mostrou-se viável para o monitoramento da qualidade ambiental dos solos, uma vez que gera informações que permitem investigar ou confirmar a ocorrência de passivos.

O objetivo desta pesquisa foi investigar a influência de fatores abióticos relacionados ao relevo e ao solo de floresta em topossequência marginal a reservatório hidrelétrico. A amostragem consistiu em 60 parcelas (200 m²cada) no estrato arbóreo e 60 subparcelas (10 m² cada) no sub-bosque, distribuídas em três setores da encosta (terços inferior, médio e superior). Nas unidades amostrais foram coletadas amostras compostas de solo para análise físico-química, além de dados de caracterização pedológica e topográfica. Por meio de abordagens estatísticas, foram analisadas as variáveis ambientais e a composição fitossociológica de cada setor da encosta, assim como suas correlações. O terço inferior se mostrou diferenciado ambiental e floristicamente dos demais e os principais fatores relacionados foram a declividade, a cota altimétrica e a concentração de matéria orgânica. A composição fitossociológica do referido setor também se mostrou diferenciada, sendo que no estrato arbóreo foi detectada influência da declividade, enquanto o sub-bosque teve influência da cota. Ambas sinúsias foram influenciadas por propriedades edáficas relacionadas à concentração de matéria orgânica.

India is one of the key producer of food grains, oilseeds, sugarcane and other agricultural products. Agricultural crops generate considerable amounts of leftover residues, with increase in food production crop residues also increasing. These leftover residues exhibit not only resource loss but also a missed opportunity to improve a farmer’s income. Crop residue burning has become a major environmental problem causing health issues as well as contributing to global warming. Composting, biochar production and mechanization are a few effective sustainable techniques that can help to curtail the issue while retaining the nutrients present in the crop residue in the soil. The main aim of this paper is to assess the amount of crop residue generated in four major crops paddy, maize, red gram and cotton of Telangana in the year 2021. The assessment of crop residue generation is done using the residue production ratio of the above four crops and the total production in the year 2021 in Telangana state. The results shows that the paddy crop generating high amount of crop residue i.e., 15,29,60,297 followed by cotton, maize and redgram. The generated crop residue is needed to be disposed or managed without causing any harm to the environment. The study suggests that the proper management of crop residue by various methods like in-situ incorporation, cattle feed, industrial purpose etc., instead of burning of the crop residue which causing environmental pollution with the emission of harmful gases.

This study proposes an effective method to map rice area using the Sentinel-1A SAR (Synthetic Aperture Radar) time series data over the Thiruvarur district during samba 2021. Fully automated MAPscape-Rice software was used to pre-process the SAR data and extraction of multi-temporal features. The rice-growing area was estimated based on the extracted multi-temporal features and statistics were derived at district and block level in Thiruvarur district. The study area registered a total rice area of 127027 ha; among the blocks, the Kottur block recorded the largest area of 16615 ha and the lowest area of 6865 ha was recorded in the Thiruvarur block. The estimated rice area was validated with the observed rice area in the Thiruvarur district using accuracy assessment, which indicates an overall accuracy of 92.0 per cent and 0.84 kappa co-efficient.

Introduction: Dental caries is a bacterial illness that causes localized disintegration and loss of calcified components in the teeth. Different plant extracts have been used to assess the anti-bacterial activity against the pathogens known to induced dental caries.

Objective: The aim of this research is to determine the antibacterial potential of Lophophora williamsii, Vinca minor, and Hydrastis canadensis against dental caries associated bacteria. Methodology: The antibacterial activity of aqueous and methanol extracts of Lophophora williamsii (LW), Vinca minor (VM), and Hydrastis Canadensis (HC) was studied. Streptococcus mutans (S. mutans), Lactobacillus acidophilus (L. acidophilus), Pseudomonas aeruginosa (P. aeruginosa), and Staphylococcus aureus were the bacteria employed (S. aureus). The disk diffusion method was used to determine the tendency of bacterial strains towards the two extracts.

Results:  S. pyogenes and S. aureus were the most susceptible bacteria, whereas P. aeruginosa was the least susceptible. The methanol extracts of Vinca minor (VM) and Hydrastis Canadensis (HC) had the highest antibacterial activity against S. pyogenes and S. aureus, whereas the aqueous extract of Lophophora williamsii (LW) had the lowest antibacterial activity against (L. acidophilus) and (L. acidophilus) (P. aeruginosa). Methanolic extracts of almost all materials outperformed aqueous extracts in suppressing pathogenic bacteria growth but were less effective than ciprofloxacin extracts used as positive controls. All of the samples had saponins, according to phytochemical analysis. Vinca minor and Hydrastis Canadensis had alkaloids, while Lophophora williamsii contained flavonoids. Only Vinca minor and Hydrastis Canadensis contained tannins, respectively.

Conclusion: Methanolic extracts of practically all materials suppressed pathogenic bacteria growth better than aqueous extracts, although not as well as ciprofloxacin extracts used as positive controls. Plant herbal blends have made major contributions to human health and well-being; as a result, plants have long been seen as a source of hope for novel therapeutic compounds.
