En este trabajo pretendemos conocer qué factores influyen en la transferencia de las formaciones en TIC destinadas al profesorado universitario, así como abordar la visión de los expertos y formadores sobre la orientación pedagógica de estas formaciones. Para ello, se han realizado entrevistas semiestructuradas a 19 expertos/as en tecnología educativa y formadores/as en TIC de universidades públicas españolas. Tras los resultados, el artículo concluye con una serie de recomendaciones para mejorar la aplicación de lo aprendido a la función docente.
Big Data, una estratégica para evitar la deserción escolar en las IES
Authors: Amaya-Amaya Arturo , Huerta-Castro Franklin , Flores-Rodríguez Carlos O.
Published: June 2020

La diversificación de modalidades educativas como e-Learning y b-learning ha permitido aumentar los índices de cobertura de la educación superior. Pero en la medida en que más estudiantes ingresan a las universidades, son más los estudiantes que no logran finalizar sus estudios de pregrado, detonando con ello los índices de deserción escolar, problema que no sólo tiene altos costos económicos y sociales a nivel nacional e internacional, sino que también genera condiciones de exclusión y de pobreza. El siguiente trabajo analiza los efectos negativos emanados de la deserción escolar universitaria, así como las características del Big Data, siendo éste una solución tecnológica viable y pertinente para brindar respuestas a esta problemática. Por otra parte, también se presentan las caracteríticas de la implementación del Modelo Analítico de Big Data de la Universidad Autónoma de Tamaulipas (UAT), así como sus resultados que permitieron identificar causas y factores que inciden en la deserción de los estudiantes universitarios.

Authors: González-Bedoya Diana-María , Molina-Osorio Ana-María
Published: June 2020

Se presentan resultados de la investigación sobre la experiencia de jóvenes universitarios de Psicología y Preescolar del Tecnológico de Antioquia que son madres/padres. Las condiciones socioeconómicas y afectivas, la feminización de la crianza y el sostén para la crianza, son hallazgos esenciales para el análisis de la deserción estudiantil, especialmente de las jóvenes madres y sus familias, en quienes se concentra la responsabilidad económica y afectiva de la crianza, un tema poco estudiado en Colombia. La metodología mixta permitió hacer diseño y pilotaje de encuesta que podrá aplicarse a toda la población estudiantil para intervenir integralmente y prevenir la deserción.
Sistem Noken Papua: Manifestasi Demokrasi Berbasis Kearifan Lokal
Authors: Ronsumbre Nelwan
Published: June 2020

The noken system, particularly related to the model of electoral balloting in Papua Province, has become an eternal topic that has been discussed and debated. The main point of the discussion is at least two aspects, namely the implementation of the noken system which is considered as local wisdom and the manifestation of deliberative democracy and in other parts that the system is considered to violate the principles of freedom and political rights of citizens. This research is a qualitative research with three research objects, namely the electoral system, deliberative democracy and political rights of citizens. This research shows that the implementation of noken in Papua is legitimate in the legal term and culturally the practice of the system is inseparable part of local wisdom and the manifestation of deliberative democracy. This study recommends the need for adjustments between the election noken system and the principles of justice, freedom and political rights of citizens through synchronization and harmonization of legal products regarding the noken system with protection of human rights in addition to the need to make incremental improvements to the system.
Classical Liberalism and Self-Reference Approach In Dealing With Harmonisation ASEAN IPR Regulations
Authors: Nurika Rizki Rahmadini , Yekti Septian Nur
Published: June 2020

ASEAN Economic Community (AEC) regulates the Intellectual Property Rights (IPR) in its relation with their economic activities. It was stipulated in the ASEAN Framework Agreement on Intellectual Property Cooperation in 1995. As the ASEAN member states are also the member of World Trade Organization (WTO), the principles of AEC have to be in harmony with the WTO principles. This paper analyzes the compliance of ASEAN IPR laws with the principles of Trade Related to Intellectual Property Rights (TRIPs) of WTO. Second, this paper analyzes the enforcement of those regulations in the member states, finding out whether there is implementation in the region that is different with the international principles or not. It is a part of qualitative research that used secondary data to complete the explanative analysis. Classical liberalism and self-reference criterion becomes theoretical framework of analysis. Classical liberalism promotes laissez-faire economics and private property in the means of production. Meanwhile, self-reference criterion refers to an unconscious reference to one’s own culture, values, knowledge, and experience as a basis for decisions. The result reveals that the ASEAN IPR regulations have different specific and special nature with the TRIPs, affected by the characteristics of the nations.
A mudança das policy na Colômbia: das políticas assistenciais de SAN até o desenvolvimento rural para a agricultura familiar
Authors: Giraldo Calderón Patricia Elena , Bedoya Bedoya María Rocío
Published: June 2020

Este artigo visa analisar a mudança ocorrida nas políticas de segurança alimentar e nutricional –SAN- na Colômbia, que tiveram por objetivo na década dos anos 2000 consolidar políticas assistenciais para combater a fome, em contraste com uma nova perspectiva emergente desde o ano 2012 no surgimento de políticas de desenvolvimento rural com ênfase na SAN e Agricultura Familiar. O trabalho baseia-se na revisão de literatura sobre as principais discussões teóricas sobre agricultura familiar, para posteriormente sistematizar o caso da Colômbia como elemento explicativo e argumentativo da hipótese aqui levantada. Ao modo de conclusões pode-se afirmar que essa guinada está associada em grande parte pelo reconhecimento mundial do papel da agricultura familiar na provisão de alimentos, assim como, a importância de mudar os padrões de produção dos alimentos.

O fortalecimento da agricultura familiar no território Alto Uruguai (RS): implementação do Programa Nacional de Alimentação Escolar (PNAE)
Authors: Tasca Eliane , Deggerone Zenicleia Angelita , Paris Cleunir Augusto
Published: June 2020

As particularidades socioeconômicas da produção agropecuária familiar motivaram as instâncias governamentais a utilizar instrumentos de política pública para viabilizar a comercialização da produção familiar, através da implementação do Programa Nacional de Alimentação Escolar (PNAE). Diante da importância deste programa, este trabalho teve por objetivo analisar os valores repassados pelo Fundo Nacional de Desenvolvimento da Educação (FNDE) referentes às aquisições do Programa Nacional de Alimentação Escolar (PNAE), para a rede estadual e municipal de ensino, no Território Alto Uruguai, Região Norte do Rio Grande do Sul, no período de 2011 a 2017. Esta pesquisa, de caráter quantitativo e qualitativo, busca, através da descrição e explicação dos dados traçar um comparativo sobre as melhorias nas condições de vida dos envolvidos a partir do programa PNAE, para tanto, utilizou-se da coleta de informações em diferentes bases de dados, além da realização de entrevistas com diferentes atores sociais, realizadas no segundo semestres de 2019. Os resultados demonstraram que, no Território Alto Uruguai, inúmeros agricultores familiares participaram deste importante canal de comercialização, ao passo que foram comercializados R$ 14.090.029,87 para o PNAE entre 2011 a 2017. Além disso, a aquisição dos produtos da agricultura familiar local pelo mercado institucional, concretizou-se em um importante espaço para promover a economia local e possibilitou aos agricultores familiares melhorias na qualidade de vida e aumento do bem-estar social de suas famílias. Por fim, enfatiza-se a importância do PNAE para a qualidade da alimentação escolar, mas também pelos seus impactos positivos no desenvolvimento socioeconômico dos agricultores familiares no Território Alto Uruguai (RS).
Heterogeneidade e dinâmicas das fontes de ocupação e renda das famílias rurais nos estados do Nordeste brasileiro
Authors: Aquino Joacir Rufino de , Nascimento Carlos Alves do
Published: June 2020

O objetivo deste artigo é analisar a heterogeneidade e as dinâmicas das fontes de ocupação e renda das famílias rurais dos estados nordestinos durante a Grande Seca que atingiu a região (2012-2015). Para tanto, utilizou-se como referência informações obtidas a partir do processamento dos microdados da Pesquisa Nacional por Amostra de Domicílios (PNAD), do IBGE. Em linhas gerais, os dados analisados mostram que, apesar dos impactos da estiagem prolongada, as áreas rurais dos estados do Nordeste não apresentaram decrescimento populacional como em épocas passadas. Esse resultado é explicado, em parte, pela diversificação das fontes de ocupação e renda das famílias rurais, que estão deixando de depender exclusivamente da agropecuária para sobreviver e se tornando cada vez mais pluriativas, não agrícolas ou, simplesmente, convertendo o campo em local de moradia. Tal processo, que apresenta dinâmicas diferenciadas entre os estados da região, tem sido facilitado no período recente pela maior sinergia entre as áreas rurais e urbanas proporcionada pela democratização dos meios de transporte e de comunicação, bem como pela rede de proteção social criada pelas políticas públicas de transferência de renda e de desenvolvimento rural.
Cultivating Social Capital through Summer Employment Programs
Authors: McMurphy Suzanne M. , Weaver Robert D. , Hrncic-Lipovic Katka , Habibov Nazim
Published: June 2020

Significant socio-economic shifts, such as the emergence of the so-called ‘knowledge economy’ have transformed the transition from adolescence to adulthood, as youth are expected to garner a considerable amount of personal, cognitive, social, and educational skills in order to successfully enter adult society and prosper within the market economy. An additional determinant of the successful transition of youth into adult society is the availability of social capital through relationships and networks that can provide access to valuable resources and information and contribute to the development of a social identity. Employment programs are a mechanism for providing youth with workforce exposure and skill development in the absence of market opportunities. These programs are also a potential source of social capital, through the exposure to new environments and the development of relationships and networks that can provide resources that youth may not have access to through traditional means. Using a qualitative approach, we explored the perspectives of youth participants in a summer employment program in Southwestern Ontario, Canada. We propose that the opportunity to develop social capital is an under-recognized benefit of employment programs, and may be a particularly important aspect for disadvantaged youth.
Developing a Cohesive Emancipatory Social Work Identity
Authors: Lorenzetti Liza
Published: June 2020

Within dominant North American discourse, individual freedom is a substantive tag line for the mind-numbing tacit approval of the loveless marriage between capitalism and democracy. This paper provides an overview of the conflicted relationship social work have with the politics of liberation, empowerment theory, and self-determination, underscoring an ongoing identity crisis, which has been dressed-up as ‘various tenets of the profession’. Connecting with the humanizing aspirations inherent to social work while building on critical and anti-oppressive theories and practices, I argue for social work to re-visualize and act on a cohesive emancipatory social work identity. True solidarity, which can only be uncovered through the relinquishing of a professional identity based on false consciousness and fear, is risking an act of love.
The Dichotomy of Sexuality
Authors: Fantus Sophia
Published: June 2020

This paper examines sexuality and the social construction of the sexual binary divide, illustrating how sexual identities have progressed, developed, and transformed.  Social categories have been created as a form of social control and have therefore perpetuated stereotypical attitudes and discriminatory acts.  This paper will illustrate how institutional and individual level harms have occurred due to the continued dichotomization of sexuality; and simultaneously how such categorizations have, in contrast, helped to form supportive and cohesive communities. Concluding, this paper will contend that dichotomous categories leave no room for individuals to question or explore their own sexuality; the sexual divide ignores the changing sexualities within today’s modern western perspective.  Deriving from a social work perspective, this paper argues that a narrative epistemological framework remains the best practice to recognize and address the complex and multifaceted nature of sexual identity.
Challenging Neo-Colonialism and Essentialism
Authors: Ying Yee June , Marshall Zack , Vo Tess
Published: June 2020

The settlement services sector in Toronto, Canada has faced difficulties in responding to lesbian, gay, bisexual, trans, and queer (LGBTQ) immigrant youth in ways that respect their specific experiences. One way agencies have taken up this challenge in Toronto has been to develop LGBTQ-specific settlement services. Housed within a diverse range of organisations, these services are intended to engage and support LGBTQ immigrant youth. In this article, we report on evaluation research conducted with LGBTQ immigrant young people from Griffin Centre’s reachOUT Newcomer Network where we asked about their experiences accessing settlement services in Toronto. Our findings suggest that LGBTQ immigrant youth are deeply influenced by intersecting identities linked to racialization, sexuality, gender identity, education, employment, and immigration status. Participants expressed overwhelming interest in accessing support, but remain disconnected from settlement services. A reconceptualization of LGBTQ settlement services within a framework of hybridity that challenges essentialism and neo-colonialism would improve service delivery. This shift would allow for more integrated settlement services that acknowledge LGBTQ newcomer youth and their experiences of (un)belonging.
Disentangling Indigenous Women’s Experiences with Intimate Partner Violence in the United States
Authors: Burnette Catherine E.
Published: June 2020

Although violence against Indigenous women is a global human rights and social justice issue, it must be examined within the local context. This article focuses on Indigenous women’s experiences with intimate partner violence (IPV). These women reside in an Indigenous community in the United States that is traditionally matrilineal. The article explores how the power and status of women have been constrained to the extent that many women now experience epidemic rates of IPV. Through the use of the theoretical framework of Paulo Freire, this critical ethnography examined how IPV is situated within a broader context of historical oppression, filling a gap in the literature with respect to understanding Indigenous women’s experiences of IPV in the United States by understanding IPV from the voices of women themselves and connecting IPV experiences to a framework of historical oppression. As part of a critical ethnography, reconstructive analysis of 29 life history interviews with Indigenous women revealed an intergenerational cycle of violence, dehumanizing tactics, and women breaking free from violent relationships. The importance of social work practitioners and researchers examining the challenges experienced by Indigenous peoples within the broader historical context of historical oppression, as well as implementing policies that enable greater self-determination for Indigenous peoples are highlighted.
Reading World Social Work Day 2010 through Multi-modal Analysis
Authors: La Rose Tara
Published: June 2020

This paper considers World Social Work Day 2010, a digital media story created and shared on YouTube by the International Federation of Social Workers. Multi-modal analysis is used to reveal the multi-vocal nature of the text and to consider the particular social work discourses used in this digital narrative. Connections between and across digital texts are used to explore the capacity of digital media to produce multiple meanings and to allow texts to exist in multiple contexts simultaneously. Post-structural perspectives framing this analysis encourage consideration of the potential meanings of globalization in social work, particularly when narrative texts are shared via online digital media environments and interpreted by both intended and unforeseen audiences.
Youth Involvement in Participatory Action Research (PAR)
Authors: Kim Jangmin
Published: June 2020

Participatory Action Research (PAR) has been increasingly viewed as an effective strategy to enhance youth, community-based organizations that serve youth, and broader communities. However, young people have not been frequently involved in research and evaluation efforts as co-researchers or partners. This paper explored major challenges and barriers to the active engagement of youth identified in previous PAR projects. This critical literature review revealed relational, scientific, and ethical challenges. The relational challenges included a lack of trust and unequal power relationships between youth participants and adult researchers. The scientific issues were significantly associated with the major components of the PAR, such as transformative purposes, iterative processes, and flexible methods. Finally, significant ethical issues are identified in terms of potential risks to youth, confidentiality, and informed consent. This paper concludes with specific recommendations for effective strategies to deal with the challenges and barriers identified and possible directions for future research.
Forefront of Human Rights Issues
Authors: Mahapatra Neely , Faulkner Monica , Schatz Mona
Published: June 2020

Curriculum content including learning strategies about human trafficking can be integrated into social work programs through the core content courses, enabling future practitioners to competently serve and advocate for victims as well as examine human trafficking policies at national and global levels. However, teaching about human trafficking is difficult due to the lack of evidence-based information. Using existing information, students can gain an understanding of an insidious worldwide phenomenon, which targets the most vulnerable populations including children, women, and youth for mere economic gains. This paper describes strategies for incorporating the topic of human trafficking as a social justice issue into core social work courses. This curricular area offers a topic of global and local significance that should be of paramount concern to the social work profession and its educators.

Heteronormativity in Norwegian Social Work Journals
Authors: Giertsen Merethe
Published: June 2020

The purpose of this review was to examine whether heteronormativity is reproduced or problematized within Norwegian social work journals. It is based on a study that explored how sexuality is addressed in social work journal articles and extends past reviews by also analysing heterosexuality. The data comprised of 572 articles published in the major Norwegian social work journals between 2002 and 2014. A keyword search and a thematic analysis was used to first determine how many articles addressed sexuality and second to develop a closer analysis of how sexuality was addressed in the identified articles. Queer theory guided the analysis. Findings revealed that heteronormativity was problematized in five of the six (1%) articles that addressed sexuality, indicating that heteronormativity is reproduced in Norwegian social work journals and that those in position in authority in the field of social work routinely deploy heterosexuality as a taken-for-granted resource. If power asymmetries are to be destabilized, strategies that counteract the power basis of the hegemonic norm are necessary, such as addressing the binary opposition of heterosexuality vs. non-heterosexuality, and naming heterosexuality.
Reply to “Do We Always Practice What We Preach? Real Vampires’ Fears of Coming Out of the Coffin to Social Workers and Helping Professionals.”
Authors: Laycock Joseph
Published: June 2020

This reply analyzes criticism of the article “Do We Always Practice What We Preach?  Real Vampires’ Fears of Coming Out of the Coffin to Social Workers and Helping Professionals” published in Critical Social Work (2015), 16(1) by DJ Williams and Emily E. Prior. That article was widely publicized and received a seemingly disproportionate amount of criticism from both religious and secular voices. This reply applies Peter Berger’s notion of anomie to suggest that critics of the article felt threatened by the implications of tolerating emerging identity claims, such as those made by self-identified vampires. By attacking Williams and Prior as unreasonable, these critics suggest that an individual’s ontological status is taken-for-granted rather than socially constructed. Paradoxically, their protests also suggest an awareness that ontological status actually is socially constructed and that helping professionals, such as Williams and Prior, are imbued with cultural authority that can alter the established order. This reply suggests that the ontological threat presented by helping professionals is what is actually at stake in these critiques. Critiquing the article appears to be not only a call for the continued medicalization of self-identified vampires as deviant, but more importantly a strategy of repressing the realization that norms are socially constructed and therefore susceptible to change.
“I Didn’t Really Want to Leave”
Authors: Metzger Molly , Oliphant Jane
Published: June 2020

With the United States’ welfare state coming to rely on market-based policies, the notion of choice has come to the forefront of public housing policy. This study investigated choice within a Chicago public housing community slated for redevelopment. In theory, the utilization of the private market creates broader options, empowering citizens to exercise greater autonomy in major life decisions. The housing authority emphasized the choices available to tenants, including the choice to remain on-site during redevelopment. Yet relocatees reported experiencing pressure to relocate, through either explicit actions from housing authority officials or nuanced channels including steering and coercion tactics. The incongruence between the narratives presented by the housing authority and those presented by the public housing residents demonstrates that the distinction between “voluntary” and “involuntary” relocation is not always clear. We offer several areas for consideration moving forward, including substantive inclusion of residents in planning processes, development of a more effective incentive structure to reward public housing agencies for relocating residents into higher quality neighborhoods, and shifting the overall framing of subsidized housing residents from consumers to civic agents who hold the potential to shape the future directions of their communities.

Tridimensional Evaluation of the Interfacial Gap in Deep Cervical Margin Restorations: A Micro-CT Study
Authors: Scotti N , Baldi A , Vergano EA , Tempesta R Michelotto , Alovisi M , Pasqualini D , Carpegna GC , Comba A
Published: June 2020

Clinical Relevance

Using a material that optimizes marginal seal when using a margin elevation technique to manage deep class II cavities should enhance clinical outcomes.

Objectives: The purpose of this laboratory study was to perform a tridimensional interfacial gap evaluation of class II cavities with enamel and dentin cervical margins, before and after cyclic fatigue, restored with different nanohybrid resin composites.

Methods and Materials: Standardized class II cavities were performed on 48 intact maxillary premolars, placing the mesial cervical margin 1 mm above the cement–enamel junction (CEJ) and the distal cervical margin 1 mm below the CEJ. Specimens were treated with two-step self-etch adhesive (Clearfil SE Bond2) and divided into six groups according to the restoration technique. Microcomputed Tomography imaging was executed before and after 1,000,000 cycles of chewing simulation at 50 N. Tridimensional interfacial gaps, expressed as cubic millimeters, were analyzed through a standardized software flowchart (Mimics). Data were analyzed with a two-way analysis of variance and Tukey post hoc tests (α=0.05).

Results: Restoration technique (p=0.001) and chewing simulation (p=0.00001) significantly influenced interfacial gap on dentin but not on enamel. The post hoc test showed that, on dentin margins, flowable resins had a lower gap at baseline but a higher gap after chewing simulation, especially when a 2-mm-thick layer was applied, compared with nanohybrid and bulk-fill composites.

Conclusions: Based on the obtained results, no differences in interfacial gap volume were found on enamel margins. On dentin margins, flowable resins showed better marginal seal at baseline, but they seem to be more prone to interfacial degradation during chewing simulation than traditional composites.

Authors: Vladimir Dimitrijević , Marko Ristanić , Ljubodrag Stanisić , Darko Drobnjak , Milivoje Urosević , Umit Ozkanal , Zoran Stanimirović
Published: June 2020

The Kangal Shepherd Dog is considered the most common dog breed of Turkish origin. This study investigated variations in ten autosomal microsatellite markers (PEZ01, PEZ03, PEZ05, PEZ06, PEZ08, PEZ12, PEZ20, FHC2010, FHC2054 and FHC2079) for the purposes of genetic diversity assessment of the Kangal breed. In addition, the use of markers was assessed in parentage testing and individual identification within the Kangal breed. The microsatellite markers were typed in 51 Kangal dogs. The total number of alleles in the study population was 69. The mean number of alleles per locus was 6.9, and varied from four (FHC2079) to 12 (PEZ12). The polymorphic information content (PIC) ranged from 0.52 (FHC2079) to 0.87 (PEZ12), with the mean value for all loci of 0.717. Power of exclusion (PE) in 10 microsatellites investigated varied between 0.143 (FHC2054) and 0.472 (PEZ08) per locus. In order to determine the efficiency of using microsatellites for individual identification in the Kangal breed, power of discrimination (PD) and matching probability (MP) were calculated for each microsatellite marker. The panel achieved high combined MP (6.77 × 10-10) and high combined PD value of 99.99999%. The obtained results may contribute to further recognition of the Kangal breed, and confirm that the investigated microsatellites enable a reliable parentage testing and individual identification of the breed.
Can Polyphenols be used as Natural Preservatives in Fermented Sausages?

Published: June 2020

This study was aimed at the investigation into the influence of polyphenols on fermented sausages produced with and without nitrite addition, during storage which lasted for 280 days. Three types of sausages were produced and formed the three experimental groups: C – the control – sausages of usual composition containing nitrites; N+P - sausages with nitrites and polyphenols; and P - nitrite-free sausages with added polyphenols. The proximate chemical composition of all groups was in the range with that of dry fermented sausages. P sausages contained 0.3 mg nitrites per kg, while C and N+P contained 54.8 mg/kg and 52.2 mg/kg, respectively. Polyphenol-enriched sausages had significantly lower peroxide and TBARS values than C sausages. In all sausages lactic acid bacteria counts reached 8.9-9.9 log cfu/g, but decreased during storage to 4.3-4.8 log cfu/g at the end of the storage period. Micrococcaceae counts remained stable: 3.5-3.9 log cfu/g. In P and N+P sausages a significantly lower number of Pseudomonadaceae was observed than in the control. The lightness of C and P sausages was similar (L=50.2 and L=49.5, respectively), while N+P sausages were darker (L=42.5). C and N+P sausages had similar redness (a*=14.5 and a*=13.2, respectively) and yellowness (b*=5.9 and b*=6.4, respectively), but the values which correspond to redness and yellowness were lower in P sausages (a*=8.0 and b*=4.6). Sensory characteristics of all products were found to be very similar. The flavour of polyphenol-enriched sausages was considered to be better. The most dominant polyphenol in sausages was kaempferol-3-O-glucoside followed by quercetin, luteolin-7-O-glucoside, catechin and syringic acid. Nitrite-free polyphenol-enriched sausages reached the same shelf life as conventional sausages containing nitrites did, which is a promising result implying that polyphenols might be used as natural preservatives and nitrite substitutes. Simultaneous use of nitrite and polyphenols is questionable due to their interactions which should be further studied.
Occurrence and Characterization of Enterotoxigenic Staphylococci Isolated from Soft Cheeses in Serbia
Authors: Radoslava Savić Radovanović , Nemanja Zdravković , Branko Velebit
Published: June 2020

A total of 415 cheese samples produced with raw or cooked milk collected from local markets were analysed for the presence of coagulase-positive staphylococci. In 85 (20.48%) samples the presence of coagulase positive staphylococci was detected. The ELFA technique VIDAS SET2 (BioMerieux, France) was used for testing coagulase-positive staphylococci strains to produce classical enterotoxins (SEA, SEB, SEC, SED, SEE), and to determine the enterotoxins in cheese samples. The number of coagulase-positive staphylococci in cheese samples ranged from 1-5.79 log CFU g-1. Out of 85 coagulase-positive strains 26 (30.59%) produced enterotoxins. The presence of genes for the synthesis of staphylococcal enterotoxins (SE) in the obtained extracts of DNA from 26 enterotoxigenic strains was detected by conventional multiplex PCR technique (for genes sea and seb) i.e. the Real-Time PCR technique for genes sec, sed and see. In all 26 strains of coagulase-positive staphylococci (originating from cheeses produced from raw or cooked milk, which were enterotoxin producers) sea was present, and in 24 strains in addition to sea gene, seb was detected. None of the isolates possessed genes for the synthesis of enterotoxin C (SEC), D (SED) and E (SEE). Out of 26 tested cheese samples positive for enterotoxigenic coagulase-positive staphylococci, enterotoxin was detected in 2 (7.69%) samples of sweet-coagulating cheese, in which the number of enterotoxigenic coagulase-positive staphylococci exceeded 5 log CFU g-1. In sweet-coagulating cheeses in which the number of coagulase-positive staphylococci exceeds 5 log CFU g-1 and the pH value was higher than 5.0, enterotoxins may be present in amounts sufficient to cause intoxication.
Immune-Mediated Hemolytic Anemia Associated with Candidatus Mycoplasma Haematoparvum in a Splenectomized Dog in Italy

Published: June 2020

This report describes a case of canine hemotropic mycoplasmasosis by Candidatus Mycoplasma haematoparvum in a dog. A five-year-old splenectomized dog was referred to the Veterinary Teaching Hospital of the University of Sassari with clinical symptoms and laboratory findings compatible with immune-mediated hemolytic anemia. Epicellular bacteria were detected in the erythrocytes by microscopic examination of blood smears. PCR and sequencing were positive for Candidatus Mycoplasma haematoparvum. Treatment with doxycycline, prednisolone and blood transfusion was administered. Several studies have described the molecular prevalence of M. hemocanis and Candidatus M. haematoparvum, however there are few clinical reports, especially those describing Candidatus M. haematoparvum infection in dogs, for which only two cases have been reported. To the best of our knowledge this is the first case report of a symptomatic infection caused by Candidatus Mycoplasma haematoparvum in Italy. Hemoplasmosis should be considered as a potential cause of hemolytic anemia in dogs. Following treatment with doxycycline and prednisolone, the clinical signs improved without resolution of infection. This condition was the same at the three-year follow-up.

Published: June 2020

This paper describes the process of creating a digital model of spiroid gears used in the defense industry. This is where the precise measurement of the parts with the highest requirements for accuracy is of great importance The construction of a computational model of a physical object was carried out using an optical three-dimensional scanner. Based on the cloud of points obtained in the process of scanning, a spatial digital model reflecting the geometry of an existing element was developed. Polygonization and mesh reconstruction allowed to create a finite element method model that enabled the precise reproduction of the scanned object. The created model was subsequently used to conduct appropriate analysis and simulation to verify the correctness and possible modification of the construction of both elements of spiroid gears: worm thread and face gear.

Β-hydroxy-β-methylbutyrate (HMB) is one of the leucine metabolites with protein anabolic effects which makes it very popular among athletes. Previously, it was shown that HMB administered during the prenatal period reduced the pool of primordial follicles and increased the proportion of developing follicles in newborn piglets. This work is a further step to understand these morphological alterations. Therefore, the aim of this study was to examine the effect of prenatal HMB treatment on the expression of the Kit ligand, BMP-4, bFGF, and the IGF-1/IGF-1R system which are the main growth factors controlling follicular development. Excised ovaries from 12 newborn piglets, originated from the control (n=6) and HMB-treated (n=6) sows were used for immunohistochemical and western-blot analysis. The tested proteins were localized within egg nests and ovarian follicles. Furthermore, the western-blot assay indicated higher BMP-4, Kit ligand, and IGF-1R expression, while the level of bFGF and IGF-1 proteins decreased after HMB dietary treatment. These findings show that HMB included into sow diet can modulate the expression of growth factors and thereby alter ovarian morphology in offspring. Therefore, this study opens a discussion about the benefits and risks of the diet supplemented with HMB and its potential application in medicine and animal husbandry, and further research is necessary in this area.

This study was conducted to investigate the in vitro and in vivo antioxidant effect of Artemisia argyi powder (AAP). 240 mixed-sex one-day-old Arbor Acres broilers were randomly divided into five treatment groups, each consisting of six replicates (one replicate per cage) with eight broilers per replicate. Broilers were fed basal diets supplemented with 0, 2.5, 5, 10 and 20 g AAP per kg feed, respectively. The hepatic and intestinal samples were collected on d 21 and 42 for analysis of antioxidant indices and antioxidative enzyme gene expression. The in vitro results showed that the scavenging activity of Artemisia argyi against •OH and DPPH were 34.99±1.11% and 74.12±0.50%, respectively; the ferric reducing power was 2.58±0.03%. The in vivo results showed that dietary 20 g/kg of AAP significantly enhanced the hepatic total antioxidant capacity (T-AOC), catalase (CAT) activity, and glutathione peroxidase (GSH-Px) activity, also decreased the malondialdehyde (MDA) content; dietary10 g/kg of AAP significantly increased the gene expression of superoxide dismutase (SOD) and CAT on d 42. For the duodenum, 10 g/kg of AAP increased SOD activity (P<0.05), and reduced MDA level (P<0.05) on d 21; the gene expression of CAT and SOD were increased in the 20 g/kg of AAP treatment compared with the control group on d 42. For the jejunum, on d 21, the T-AOC level was increased by inclusion of 10 g/kg of AAP, and CAT activity was enhanced significantly at 5, 10, and 20 g/kg of AAP group; dietary AAP significantly decreased MDA level at the concentration of 2.5, 5, 10 and 20 g/kg in contrast with control group on d 42; 5 and 20 g/kg of AAP increased the gene expression of SOD on d 21, and the gene expression of GSH-Px was increased (P<0.05) in 10 g/kg of AAP group on d 42. For the ileum, compared to the control group, 2.5 and 20 g/kg of AAP increased SOD activity (P<0.05); and dietary 10 and 20 g/kg of AAP significantly reduced MDA level; dietary 10 g/kg of AAP increased the gene expression of SOD, CAT and GSH-Px in broilers on d 42. In conclusion, dietary AAP could improve the antioxidant defenses of liver and small intestine, and the best concentration of the AAP improving hepatic and small intestinal antioxidant status was 20 g/kg and 10 g/kg, respectively.

Hemiplegia is the lifelong paralysis, caused by brain stroke that affects one side of the body. Stroke exerts a great threat to patient’s health and lives, and hemiplegia after stroke may severely affect their activities of daily life including self-dressing that causes fatigue and frustration and ultimately ended with “dependence on others.” This situation damages the sense of dignity, especially for women, while independently dressing intimate apparel like bra. The research through the design approach is used as the conceptual framework to design and evaluate bra for the women with hemiplegia. Three design criteria were identified from which specifications were developed, and their interrelationships explored through an interaction matrix. This article presents a research work on improving bra design, adjusted to the special needs and demands of an individual with hemiplegia, by using bi-layer knitted fabric, magnetic fasteners, and shape-memory alloys. The findings of the current study showed that adaptive bra design offers independence, concealment of the disability, and comfort and psychological contentment. This adaptive bra promotes the harmony between functionality and esthetics.

This article is a dimensioning study of the landfill locker dike of the city of Casablanca, where the geotechnical parameters of waste have particular limitations, theses limitation are a common characteristic for most developing countries. Considering the very small available land area in general, the objective is to achieve an optimal dimensioning of the locker to maximize the volume to be buried, while respecting the requirements of stability of the structure; namely, the model whose safety factor will be greater than 1.5. The Factor of Safety (FoS) was calculated by the Finite Element Method (FEM) using “PLAXIS 2D” software. The results show that, for both cases (with and without final cover), FoS, as obtained from both the analysis, show a similar pattern, with the maximum FoS for low inclinations, especially those lower than 15.95°. The critical FoS (< 1), was obtained for slopes strictly greater than 21.80°. The study also demonstrated that the 3.5H 1V model could be considered as the optimal one that satisfies the structural stability requirements (FoS> 1.5) and maximizes the volume to be buried. Nevertheless, the validation of this model is conditioned by a geometric modification (weakening the lateral slope of the landfill, by moving the dikes by 3 m) and the improvement of the mechanical characteristics of the soil of the peripheral dike, through replacing the material with the compacted clay. This model was validated by PLAXIS, which showed that the FoS for the phase preceding the anchoring of the final cover is 1.577, which reaches 1.604 after anchoring.

Surface water, especially rivers, is the most important sources of water supplies for drinking, agricultural and industry use and livelihoods. Controlling the pollution of BalikhlouChai River as one of the most important sources of water supply in Ardabil province in Iran is very significance and vital. In this research, the pollution zoning by using the Spatial Multi-Criteria Evaluation (SMCE) model in BalikhlouChai River was carried out to evaluate the trend of changes in water index and other important parameters by considering the physicochemical, biological, socio-economic and cultural constraints. First of all six stations were selected in the study zone and the sampling was performed over a 12 months period, and then the average of obtained parameters was compared with the standard values of Department of Environment in Iran. The results showed that fecal coliform in most stations and BOD5 in stations 4 and 5, and Nitrate in the stations 4, 5, and 6 were more than standard. Next, the related factors and criteria with the changes in pollution trend in river was identified, weighted and prioritized by the Analytical Network Process (ANP) model. Then the basic maps were prepared and the information layers were incorporated into the SMCE model. Finally, the zoning map of BalikhlouChai River specified in terms of pollution and river health in two contaminated and safe areas in the study basin. According to the results of this study, 3 zones for the safe and 3 zones for the contaminated areas in the study region of river basin were determined which respectively the numerical values of 1, 0.85 and 0.75 for the safe zones and 0.2 and 0.1 and about zero values for the contaminated zones were calculated. The results of quality and quantity zoning indicate that the northeast regions of the study area, including Ardabil City outlet and the Qarasu River basin have gained almost zero value.

The article deals with the interaction of a reinforced concrete slab with subsoil. The paper contains a non-linear analysis based on an experiment of reinforced concrete slabs with dimensions 2000 x 2000 mm and thickness 150 mm. A steel mesh with a diameter of 8/100 mm was used as reinforcement. The calculations and analysis are complemented by a comparison with EC2 design approaches. The research area combines the design of concrete structure and geotechnical tasks. The real behavior of the concrete structure with subsoil is considered for the analysis for advanced design. The selected computational approach of nonlinear analysis allows to capture the change of stiffness after the creation of cracks and modelling the shear punch failure of the slab - the collapse of the structure. The paper focuses on comparing the experiment with the numerical model in select loaded states for various input parameters of subsoil. Based on the experiment and numerical analysis the failure mechanism was determined. It was the punching of the slab. The calculations and the experiment verified that the critically controlled perimeter is at a distance of 1d. The effect of the modulus of elasticity on the slab punch mechanism was verified. In case of low modulus of subsoil, the load-bearing capacity of the slab is significantly reduced. The punching mechanism is influenced not only by the mechanical properties of the concrete but also by the properties of the subsoil. The performed parametric study also verified the influence of the size the nominal cover reinforcement depending on the modulus of elasticity of the subsoil. The deformation variant finite element method and a 3D computational model were used for numerical modelling. Nonlinear analysis was based on the Newton-Rapson method.
