The microstructure and distribution of residual stresses in AMr6 alloy after the laser shock processing in the range of power density 1—6 GW / cm2 have been studied. By the X-ray diffraction method it was found that domain size decreased up to 60 nm, microstrains increased up to 0,0018 and average dislocation density increased by a factor of 5,5 in comparing with untreated material (3,7×1014 м–2 vs. 6,6×1013 м–2). The laser shock processing generates residual compressive stresses in depth up to 1 mm, with a maximum of –128 MPa on the surface of the material.

Published: April 2020

There has been a recent surge of interest in using mobility data from mobile phones to monitor social distancing and model the spread of SARS-COV-2, the virus that causes COVID-19. Despite several years of research in this area, standard frameworks for aggregating and making use of different data streams from mobile phones are lacking and difficult to generalize across data providers. Here, we provide a comprehensive set of guidelines for aggregation principles and procedures for different mobile phone data streams, and describe how aggregated data are used in research and policy. We argue that the principles of privacy and data protection are critical in assessing more technical aspects of aggregation, and should be an important central feature guiding partnerships with governments who make use of research products.
Narkoba dan Dunia Malam sebagai Sebuah Fenomen
Authors: Iwamony Rachel
Published: April 2020

Narkoba merupakan salah satu masalah yang mendapat perhatian serius seluruh masyarakat Indonesia. Hal ini disebabkan karena akibat yang ditimbulkan oleh penyalahgunaan narkoba sangat besar. Selain dampak negatifnya terhadap kesehatan, psikis pengguna juga akan mengalami gangguan, sehingga pengguna tidak dapat berpikir positif menjalani hidupnya; termasuk merancang dan menggapai masa depannya yang lebih baik. Oleh karena itu, narkoba dilihat sebagai ancaman serius bagi masa depan generasi muda. Ini berarti juga narkoba adalah juga ancaman serius bagi masa depan suatu bangsa. Disadarai juga bahwa Narkoba memiliki keterkaitan yang erat dengan Dunia Malam, yang sangat sering dipandang negatif. Atas dasar kesadaran itu, PERSETIA menetapkan Narkoba dan Dunia Malam sebagai tema dari Kongres Nasional Mahasiswa Teologi Indonesia (KNMTI), tahun 2017. Hasil KNMTI 2017 inilah yang kemudian diterbitkan sebagai Prosiding pada tahun 2019, dengan ISBN: 978-979-3130-27-9. Tulisan-tulisan dalam prosiding ini mengajak pembaca untuk memahami realitas Narkoba dan Dunia Malam secara utuh.

Character Deprecation in Fake News: Is it in Supply or Demand?
Authors: McPhetres Jonathon , Rand David Gertler , Pennycook Gordon
Published: April 2020

A major focus of current research is understanding why people fall for and share fake news on social media. While much research focuses on understanding the role of personality-level traits for those who share the news, such as partisanship and analytic thinking, characteristics of the articles themselves have not been studied. Across two pre-registered studies, we examined whether character deprecation headlines—headlines designed to deprecate someone’s character, but which have no impact on policy or legislation—increased the likelihood of self-reported sharing on social media. In Study 1 we harvested fake news from online sources and compared sharing intentions between Republicans and Democrats. Results showed that, compared to Democrats, Republicans had greater intention to share character-deprecation headlines compared to news with policy implications. We then applied these findings experimentally. In Study 2 we developed a set of fake news that was matched for content across pro-Democratic and pro-Republican headlines and across news focusing on a specific person (e.g., Trump) versus a generic person (e.g., a Republican). We found that, contrary to Study 1, Republicans were no more inclined toward character deprecation than Democrats. However, these findings suggest that while character assassination may be a feature of pro-Republican news, it is not more attractive to Republicans versus Democrats. News with policy implications, whether fake or real, seems consistently more attractive to members of both parties regardless of whether it attempts to deprecate an opponent’s character. Thus, character-deprecation in fake news may in be in supply, but not in demand.

Sports-related brain injury is very common, and the potential long-term effects include a widerange of neurological and psychiatric symptoms, and potentially neurodegeneration. Aroundthe globe, researchers are conducting neuroimaging studies on primarily homogenoussamples of athletes. However, neuroimaging studies are expensive and time consuming, andthus current findings from studies of sports-related brain injury are often limited by smallsample size. Further, current studies apply a variety of neuroimaging techniques and analysistools which limit comparability among studies. The ENIGMA Sports Injury working group aimsto provide a platform for data sharing and collaborative data analysis thereby leveragingexisting data and expertise. By harmonizing data from a large number of studies from aroundthe globe, we will work towards reproducibility of previously published findings and towardsaddressing important research questions with regard to diagnosis, prognosis, and efficacy oftreatment for sport-related brain injury. Moreover, the ENIGMA Sports Injury working group iscommitted to providing recommendations for future prospective data acquisition to enhancefurther, both, data quality and scientific rigor.
TRENDS IN PERCEPTION OF COVID-19 IN POLISH INTERNET
Authors: Jarynowski Andrzej , Wójta-Kempa Monika , Belik Vitaly
Published: April 2020

INTRODUCTION: Due to the spread of SARS CoV-2 virus responsible for COVID-19 disease, there is an urgent need to analyse COVID-2019 epidemic perception in Poland. This would enable authorities for preparation of specific actions minimizing public health and economic risks. This study aims to illustrate the media exposure of the social perception of coronavirus using the means available during the epidemic and our goal is to signal the main issues in public perception and medical commutation in real time.METHODS: We study the perception of COVID-2019 epidemic in Polish society using quantitative analysis of its digital footprints on the Internet (on mainly Google and supported by Twitter, YouTube, Wikipedia and electronic media represented by Event Registry) from January 2020 to 07.04.2020 (before and after official introduction to Poland on 04.03.2020). To this end we utilize trend analysis with a support of simple natural language processing techniques. Each examined internet platform was analysed representativeness and composition of the target group too.RESULTS: We identified three temporal major clusters of interest before disease introduction on the topic COVID-2019: China- and Italy-related peaks on all platforms, as well as a peak on social media related to the recent special law on combating COVID-2019. Besides, there was a peak in interest on the day of officially confirmed introduction as well as an exponential increase of interest when the Polish government “declared war against disease” around 11/12.03.2020 with a massive mitigation program. Later on, there is a decay in interest with additional phases: social distancing and anticrisis act with local peaks. From a sociolinguistic perspective, we found that concepts and issues of threat, fear and prevention prevailed before introduction. After introduction, practical concepts about disease and epidemic dominate. We have found out that declarations of mitigation strategies by Polish Prime Minister or Minister of Health gather high attention on Internet users. So enacted or in force events do not affect interest in such an extent. We have observed very low correlation between colloquial searching term 'antiviral mask' in Wikipedia and encyclopaedic definition at Wikipedia “SARS-CoV-2”, which suggest that there are different mechanisms for searching for knowledge against panic related behaviour. CONCLUSIONS: Traditional and social media do not only reflect reality, but also create it. As traditional media ahead social media in time, we advise to choose news for a quick dissemination of information, however for a greater impact, social media should be used. Otherwise public information campaigns might have less impact on society than expected. For greater penetration, it might be necessary to diversify information channels to reach as many people as possible.
Political Ideology and the Outbreak of COVID-19 in the United States
Authors: Rosenfeld Daniel L.
Published: April 2020

At the state level within the United States, did political ideology predict the outbreak of the novel coronavirus (COVID-19)? Throughout March 2020, the United States became the epicenter of the COVID-19 pandemic, recording the most cases of any country worldwide. The current research found that, at the state level within the United States, more conservative political ideology predicted delayed implementation of stay-at-home orders and more rapid spread of COVID-19. Effects were significant across two distinct operationalizations of political ideology and held over and above relevant covariates, suggesting a potentially unique role of political ideology in the United States’ COVID-19 outbreak. Considering political ideological factors may offer valuable insights into epidemiological processes surrounding COVID-19.
SUICIDE ATTEMPTS IN TURKISH UNIVERSITY STUDENTS: THE ROLE OF COGNITIVE STYLE, HOPELESSNESS, COGNITIVE REACTIVITY, RUMINATION, SELF-ESTEEM, AND PERSONALITY TRAITS
Authors: Aslan Esma Akpınar , Batmaz Sedat , Yıldız Mesut , Songur Emrah
Published: April 2020

Background: Suicide is one of the major public health problems in young adults. Detecting the risk factors and correlates among university students might help identify students who are under risk and who need early interventions for suicide prevention.Aims: The current study aimed to investigate the cognitive style, self-esteem, hopelessness, rumination, cognitive reactivity, and personality characteristics of Turkish university students, who previously attempted suicide and who did not.Method: A total of 355 university students (34 previous suicide attempters) were recruited for this study, and they completed the Ten-Item Personality Inventory (TIPI), the Ruminative Response Scale (RRS), the Leiden Index of Depression Sensitivity–Revised (LEIDS-R), the Beck Hopelessness Scale (BHS), the Cognitive Style Questionnaire–Short Form (CSQ), the Rosenberg Self-Esteem Scale (RSES), and the Hospital Anxiety and Depression Scale (HADS).Results: Higher RRS, BHS, CSQ scores and lower TIPI-A and RSES scores were significantly associated with a previous suicide attempt.Conclusion: Negative cognitive style, hopelessness, and rumination were significant correlates of a previous suicide attempt. These cognitive factors may be targets in psychotherapy to reduce suicide attempts in college-age individuals.

Published: April 2020

The COVID-19 mitigation measures require a fundamental shift in human behavior. The present study assesses what factors influence Americans to comply with the stay at home and social distancing measures. It analyzes data from an online survey, conducted on April 3, 2020, of 570 participants from 35 states that have adopted such measures. The results show that while perceptual deterrence was not associated with compliance, people actually comply less when they fear the authorities. Further, two broad processes promote compliance. First, compliance depended on people’s capacity to obey the rules, opportunity to break the rules, and self-control. As such, compliance results from their own personal abilities and the context in which they live. Second, compliance depended on people’s intrinsic motivations, including substantive moral support and social norms. This paper discusses the implications of these findings for ensuring compliance to effectively mitigate the virus.
Developing and Enhancing Adherence to a Telehealth ABA Parent Training Curriculum for Caregivers of Children with Autism
Authors: Yi Zhihui , Dixon Mark R.
Published: April 2020

The current COVID-19 pandemic poses unique challenges to the delivery of ABA services and there has been a growing demand for evidence-based practices on how to develop a telehealth ABA service model. The current paper provides a detailed technological guide on how to develop a telehealth ABA parent training curriculum. Our model also includes a series of brief Acceptance and Commitment Training (ACT) protocols to enhance parental adherence. We provide the details for replicating our telehealth model, and also demonstrate its effectiveness. To begin, a step-by-step guide on how to develop this curriculum is presented, as well as protocols used in a 60-day telehealth ABA parent training program. Afterwards we describe a randomized controlled trial design to examine the effectiveness of this protocol. Thirteen families from the southern Illinois region participated in the curriculum before the COVID-19 outbreak. Obtained data indicated training was effective to teach skills, and parents with supplemental ACT material made significantly more progress than those in the control group, t(11) = 2.36, p = .044. Half-way through the training, the outbreak of COVID-19 occurred, and parents in the ACT group were more likely to continue the program while parents in the control group were significantly more likely to postpone their participation, χ2 = 6.96, p = .008. Social validity measures indicated that parents rated the curriculum favorably. Limitations and suggestions for practitioners are discussed.
Misdirection: model of information process for neuromagic
Authors: Bestue David
Published: April 2020

Neuromagic is underpinned by the union of neuroscience and magic. However, the contribution between them is unbalanced. While neuroscience has used magic tricks to study different cognitive processes and develop sophisticated experiments, the returned contribution has not penetrated into magicians praxis. In neuroscience, a priori theories are supported by objective experimental data. However, this steps are switched in magic: subjective experimental evidence generates a posteriori theories. This scientifically invalid methodology leads, as a consequence, to several unvalidated theories about the same topic. To solve this problem, testing this theories with previously validated brain models is essential, as it will separate the ones that can be reproduced with realistic models from the ones that can not. Here, we use a popular brain model -the bump attractor- to describe the most studied magical principle: misdirection. Misdirection aims to avoid the detection of tricky maneuvers by affecting the attention and the memory of the spectators. Misdirection is been defined and classified in multiple ways for different magicians. For the first time, we will support with a model of neural activity, a recent misdirection classification (Bestue, 2019). The model reproduced the efficiency and provided a neural explanation for each of the three different subcategories of misdirection proposed by the classification: “direction”, “division” and “diminishment”. That way, we provided first neuroscientific evidence for a misdirection classification. We hope this work motivates both magicians and neuroscientists to provide detailed models to different magical principles, so they rely in objective brain functioning and not in subjective psychological theories.
The Politics of Platform Capitalism. A Case Study on the Regulation of Uber in New York
Authors: Seidl Timo
Published: April 2020

Platform companies like Uber not only disrupt existing markets but also contest existing regulatory regimes. This raises the question of how, when, and why such companies are regulated. This paper develops, tests and defends a theoretical framework that explains the politics of regulatory response to the rise of platform capitalism. Using discourse network analysis and a case study on the regulation of Uber in New York, it shows that the success or failure of regulations depends on the ability of actors to mobilize broad coalition; that narratives affect the composition of these coalitions; and that platform companies have both unique political strengths and vulnerabilities. The paper makes substantive contributions to our understanding of the politics of platform capitalism, and it makes theoretical contributions to the literatures on coalitional politics, ideational institutionalism, and business power.

Published: April 2020

Our study aimed to examine athletics, training characteristics, and prevalence of musculoskeletal symptoms of male junior tennis Davis Cup players (DC) in comparison with their regional counterparts, as well as to evaluate the impact of age and performance level on training characteristics. Twelve junior DC (male) and two samples of regional squad players (RS1 n = 60 males, n = 47 females; RS2 n = 59 males) participated in a physical testing, an interview for data evaluation on training characteristics, and a questionnaire survey of orthopedic injury frequency. Results indicate higher physical performance levels (effect size (ES) 0.75–1.26) and training volumes in DC (ES 1.23–1.66). In DC, significant relationships were found between total training volume and tennis ranking (r = −0.78), age and physical training volume (r = 0.82), and age and total training volume (r = 0.62). Injury frequencies showed moderate to high prevalence with no differences (p > 0.05) between DC and RS. Given the demands of elite tennis and the important role of service in the modern game, more efforts are necessary to develop training prescription for both performance enhancement and prevention strategies.

The “Refugee Crisis” as a Eurocentric Media Construct: An Exploratory Analysis of Pro-Migrant Media Representations in the Guardian and the New York Times
Authors: Avraamidou Maria
Published: April 2020

This article presents a critical analysis of how two elite media publications in the United States and the United Kingdom, the New York Times and the Guardian/Observer respectively, represented the so-called European refugee crisis in their editorials. The study foregrounds a media aporia of why Europe did not abide with human rights and democratic values vis-à-vis the refugee drama and a subsequent nostalgia for a European past of democracy and transnational unity that never really existed. These media representations, although sympathetic towards migrants, are inherently Eurocentric, helping to reproduce the existing repressive global migration regime because they do not see the crisis as a continuation of its coloniality but as a rupture.
Is Anterior-Only Fixation Adequate for Three-Column Injuries of the Cervical Spine?
Authors: Sethy Siddharth Sekhar , Ahuja Kaustubh , Ifthekar Syed , Sarkar Bhaskar , Kandwal Pankaj
Published: April 2020

Study Design: Retrospective case series.Purpose: To analyze the clinical and functional outcomes of patients who have undergone anterior cervical discectomy/corpectomy and fusion (ACDF/ACCF) for a three-column cervical spine injury (CSI).Overview of Literature: The treatment of choice for a three-column CSI is an area of contention; however, combined anterior and posterior fixation is the preferred method explored in the literature. Studies have shown the superior biomechanical stability of posterior fixation over that of anterior fixation, but anterior-only approach in CSI has been proving its efficacy in recent times by providing reasonable stability with the maximum achievable decompression and fusion.Methods: Twenty-one patients undergoing ACDF/ACCF with a bone graft/metallic cage treatment for cervical injuries involving all three columns from January 2016 to July 2018 were included in the study. All of the patients were followed up monthly for the first 3 months and then every 6 months, until their last follow-up visit.Results: Nineteen patients had AO type C injuries and were managed with ACDF, and two patients with AO type B injuries were managed with ACCF. Fifteen had a complete spinal cord injury, while six had an incomplete spinal cord injury (American Spinal Injury Association B, C, and D). The mean segmental kyphosis at presentation of 12.2°±4.4° improved in the postoperative period to -7.2°±2.5°. At their final follow-up, all the patients showed clinical improvements when assessed by the Visual Analog Scale (6.8–1.8), Oswestry Disability Index score (59.7–34.9), and Spinal Cord Independence Measure score (24.8–36.4). One patient in the ACDF group needed a secondary posterior fixation because of instability.Conclusions: An anterior approach to the cervical spine in cervical fracture dislocations is an effective treatment showing an optimal recovery rate in terms of patient-reported outcomes and structural stability, with the added advantages of less blood loss and the fact that the technique requires less instrumentation.

The total content of phenol compounds present in the liquid smoke can be extracted either by using polar or non-polar solvents. Polar and non-polarsolvents are often used to extract phenol compounds from plants. Extraction of phenol compounds was performed by using ethyl acetate and hexanesolvents at 40° C, 55° C and 70° C within 60, 120, and 180 minutes. The highest total content of phenol compounds is obtained through extractionprocess at 70o C within 180 minutes using ethyl acetate solvent, which is 103,394 mg/g. While, the lowest one is obtained through extraction processat 40o C within 60 minutes using hexane solvent, which is 13,697 mg/g. The phenol compounds obtained are syringol and guiaicol compoundsusing ethyl acetate solvent within 180 minutes, at the temperature of 70o C, which is 5,44% and 3,97%.
Heuristic derivation of Brinkman's seepage equation
Authors: Wojnar Ryszard
Published: April 2020

Brinkman’s law is describing the seepage of viscous fluid through a porous medium and is more acurate than the classical Darcy’s law. Namely, Brinkman’s law permits to conform the flow through a porous medium to the free Stokes’ flow. However, Brinkman’s law, similarly as Schro¨dinger’s equation was only devined. Fluid in its motion through a porous solid is interacting at every point with the walls of pores, but the interactions of the fluid particles inside pores are different than the interactions at the walls, and are described by Stokes’ equation. Here, we arrive at Brinkman’s law from Stokes’ flow equation making use of successive iterations, in type of Born’s approximation method, and using Darcy’s law as a zero-th approximation.

Published: April 2020

This study aims to obtain an overview of the current situation of the use of instructional media in science teaching process in elementary school, the perception and challenges faced by primary school teachers in delivering the digestive system subject matter and the formulation of learning media needs to be developed in science teaching on the digestive system materials. This study involved teachers and students in elementary schools around Surakarta in aimed to understand their accessibility potential by knowledge, types of media used, and to state their perceptions to adopt media in classroom. The results which are analyzed by using descriptive qualitative approach indicated that 1) the current use of instructional media in science learning process has not been carried out optimally. 2) There are challenges in the delivery of material, primarily abstract and conceptual materials since the teacher needs a media to visualize the process and explain it in detail and correctly so that students do not have misconceptions about the process of digestive system. 3) There is a need for learning media to be developed in learning the material, especially in form of audiovisual media. This result can be a consideration in developing science learning media for elementary school.

La responsabilidad social de la empresa: ¿el coste de tener conciencia?
Authors: Redacción Consejo de
Published: April 2020

La Revista reﬂexiona de nuevo sobre el tema de la Responsabilidad Social de la Empresa (RSE), entendida en el sentido de la incorporación por parte de la empresa de los problemas sociales y medioambientales en sus operaciones, así como de sus relaciones con las personas o grupos con los que está implicada. Se subraya el interés del tema a causa de dos fenómenos: la globalización y la crisis del Estado social. Se hace una revisión histórica del concepto que en los tiempos más recientes se vincula con el término “stakeholders”. Se insiste en el peligro de convertir la responsabilidad social en un tópico, considerando también la eﬁcacia real de la RSE. Asimismo, se indican las líneas o tareas en las que habría que trabajar para avanzar en el tema. Finalmente, se alude a un nuevo modelo de empresa que responda a la realidad social de un mundo globalizado. La Revista de Fomento Social apuesta por este modelo que se debe basar en un principio de colaboración.

Sobre agricultura y agricultores. Reﬂexiones en un periodo de transición
Authors: Moyano Estrada Eduardo
Published: April 2020

Se expone que la modernidad en la agricultura no se mide con criterios de eﬁcacia sino de eﬁciencia (buen uso de los recursos). La externalización de actividades agrarias y el desarrollo de empresas de servicio en el mundo rural representan un nuevo escenario en este medio. La nueva estrategia de una agricultura dual se basa en explotaciones empresariales de carácter competitivo y en un modelo de agricultura multifuncional fuertemente integrada en el territorio. Respecto a las políticas públicas no se puede esperar que todas las orientaciones y decisiones procedan de “Bruselas”; las políticas del Estado central y de las Comunidades autó de las Comunidades autó de las Comunidades autónomas deben tener un cierto protagonismo en dicha estrategia, que debe insistir en la diversiﬁcación. Se propone ﬁnalmente un Pacto por el Desarrollo Rural y el medio ambiente.
Las competencias: un factor clave en la empleabilidad de los titulados universitarios El proceso de armonización
Authors: Ariza Montes José Antonio
Published: April 2020

El proceso de armonización de los distintos sistemas educativos de la unión Europea implica una reorganización conceptual de la formación donde se reconoce, entre otras cuestiones, la importancia de las competencias para el desarrollo curricular del discente y, por ende, para mejorar su empleabilidad. sin embargo, hablar de competencias supone adentrarse en un mundo opaco donde se fusionan términos como conocimientos, características personales, habilidades, aptitudes, destrezas, etc. Alguno de estos fenómenos constituye la base de la inteligencia clásica, mientras que otros apoyan y sustentan las capacidades de las personas dotadas de inteligencia emocional. En este trabajo se ponen de manifiesto, en primer lugar, los principales cambios acaecidos en el mercado laboral en los últimos años; en segundo lugar, se analiza el conflicto inteligencia–competencias como eje de la empleabilidad y, por último, se exponen las principales conclusiones de un reciente estudio que pone en evidencia la importancia de las competencias emocionales en la empleabilidad de los recién titulados universitarios.

Authors: Nguyen Thanh Hong , Nguyen Nguyen Tran Tu , Nguyen Thoa Thi Phuong
Published: April 2020

Biodiesel was prepared from catfish fat by alkaline-catalyzed transesterification with methanol. Using ultrasonic irradiation considerably sped up the transesterification and the phase separation as well as reduced by-product formation in the product in comparison with the heat-chemical method. The basis factors, such as content of catalysts, reaction time, dissolved time of catalyst in methanol, mol ratio of reactants, ultrasonic power, etc. were investigated and optimized. Biodiesel yield was more than 90%. Obtained biodiesel fuel was up to the Vietnamese standard for biodiesel fuel blend stock (B100).
How Can Sustainable Agriculture Increase Climate Resilience? A Systematic Review
Authors: El Chami Daniel
Published: April 2020

In the last few decades, a great deal has been written on the use of sustainable agriculture to improve the resilience of ecosystem services to climate change. However, no tangible and systematic evidence exists on how this agriculture would participate in alleviating impacts on vulnerable rural communities. This paper provides a narrative systematic review (SR) integrated with a bibliometric analysis and a concept network analysis to determine how, in this changing climate, sustainable agriculture can increase the resilience of agrosystems. Our search ranged from the date of the first relevant article until the end of 2018.
Deep Cryogenic Treatment of Metallic Materials
Authors: Jovičević-Klug Patricia , Podgornik Bojan
Published: April 2020

Deep cryogenic treatment (DCT) is a type of cryogenic treatment, where a metallic material is subjected to temperatures below -150°C, normally to temperatures of liquid nitrogen (-196 °C). When a material is exposed to DCT as a part of heat treatment, changes in microstructure are induced due to new grain formation, changes in grain size, change in the solubility of atoms, movement of dislocations, alteration of crystal structure, and finally new phase formation. The metallic material's performance and later performance of manufactured components and tools from this specific material are dependent on the selection of proper design, proper material, accuracy with which the tool is made and application of proper heat treatment, including any eventual DCT. Metallic materials are ferrous and non-ferrous metals. In the last years ferrous metals (different grades of steel) and non-ferrous alloys (aluminum, magnesium, titanium, nickel etc.) have been increasingly treated with DCT to alter their properties. DCT treatment has shown to reduce density of defects in crystal structure, increase wear resistance of material, increase hardness, improve toughness, and reduce tensile strength and corrosion resistance. However, some researchers also reported results showing no change in properties (toughness, hardness, corrosion resistance, etc.) or even deterioration when subjected to DCT treatment. This leads to a lack of consistency and reliability of the treatment process, which is needed for successful application in industry. This review provides a synopsis of DCT usage and resulting effects on treated materials used in automotive industry.
Analysis of tests used in detection/diagnosis of SARS-CoV-2/COVID-19
Authors: Apostolou Panagiotis
Published: April 2020

Latest weeks the humanity is faced with the spread of a new coronavirus, SARS-CoV-2 that causes a respiratory illness with high mortality rates, COVID-19. Since there is no approved treatment or vaccination against that specific coronavirus the reduce in virus spread is essential. That is based in the use of appropriate tools, enabling the accurate and early detection. Molecular biology and immunological techniques are widely used in order to predict the COVID-19 cases in a very short period of time. These are commonly based either in identification of the SARS-CoV-2’s genetic material or in detection of antibodies that have been produced by the immune system against the virus. Many of the above mentioned tests have been validated and approved by local authorities. However, there are much more companies that provide detection tests, without basic validation processes, contributing in non-precise data. The present review aim to analyze the most common platforms that are used in COVID-19 detection, analyzing their advantages and weaknesses. Therefore, each physician will be equipped with appropriate information required for each test.
Membrane Lipid Switches: How Membrane Lipid Structure Influences Protein–Lipid Interactions
Authors: Torres Manuel , Rosselló Catalina Ana , Fernández García Paula , Llado Victoria , Escribá Pablo V
Published: April 2020

Peripheral membrane proteins are required for signal propagation upon ligand-induced receptor activation at the plasma membrane. The translocation of this amphitropic peripheral proteins from or to the plasma membrane enables signal cascade propagation into the cells. This translocation greatly depends on the membrane’s lipid composition and, consequently, regulation of the lipid bilayer emerges as a novel therapeutic strategy. Indeed, relevant changes in membrane lipids can induce massive translocation of peripheral signaling proteins from or to the plasma membrane, which controls how cells behave. We called these changes “lipid switches”, as they alter the cell’s status (e.g., proliferation, differentiation, death, etc.) in response to the modulation of membrane lipids. This discovery enables therapeutic interventions focused on modifying the bilayer’s lipids, an approach known as membrane-lipid therapy (MLT) or melitherapy.

Authors: Sopiatun Siti , Maryati Sri
Published: April 2020

Stunting is a condition of failure to thrive in children under five years due to chronic malnutrition so that the child is too short for his age. Malnutrition appears when the baby is in the womb and the early period after the baby is born. The purpose of this study is how the Continuum of Care Program is implemented, analyze cross-sectoral, and cross-program support in nutritional surveillance to prevent and manage stunting. The study design used a cross-sectional survey approach. The results of research from 6 Puskesmas working areas showed the highest number in Puskesmas Lemah Duhur with an incidence of stunting 81%, had a continuum of ineffective stunting treatments with an average of 63.84 and less available treatment centers with an average of 63.75. There are obstacles in sending information that occurs from the Puskesmas to posyandu cadres related to stunting. The range of treatments in providing effective care and place of care has the most significant impact on maternal health, the health of newborns, and children related to the incidence of stunting in each region. Collaboration and cross-sector programs are needed in stunting prevention by the government.

Published: April 2020

Pela capacidade de algumas bactérias viverem em mutualismo com o reino vegetal, nos propusemos a estudar a eficácia de uma em específico, a bactéria Azospirillum brasilense, a qual, tem ganhado visibilidade no mercado agrônomo. Quatro amostras de feijões foram cultivadas durante 20 dias, todas recebendo tratamentos idênticos. Cada amostra foi cultivada em terra específica, na qual, duas das amostras possuíam presença da bactéria arada junto ao solo, uma inclusive possuindo, além da presença da bactéria, também adubo químico. Após os 20 dias de cultivo, tornou-se evidente a maior capacidade de crescimento adquirida pelas amostras na presença da bactéria, além de ter demonstrado um resultado ainda melhor quando cultivada em conjunto com o adubo químico. Os resultados nos fizeram concluir que a bactéria Azospirillum brasilense arada ao solo antes do cultivo de feijão proporciona maior poder de crescimento desta leguminosa, efeito que se manifestou no crescimento do caule e da raiz.
