A supressão da vegetação nativa para a expansão agropecuária ou para outro tipo de uso, tem agravado o processo de degradação florestal, ocasionando impactos negativos. Assim, este estudo teve como objetivo o mapeamento da vegetação da APP no Horto Florestal Olho D´água da Bica, do município de Cuité – PB, quantificando as áreas alteradas da vegetação densa, vegetação rala e o solo exposto, através das mudanças espectrais em quatro anos (2015 a 2018), visando obter maior conhecimento sobre a sua preservação. Foram utilizadas imagens de satélite Landsat 8 que possuíam menores coberturas de nuvens. A interpretação visual de imagens de satélite ocorre através da extração de padrões texturais nas bandas monocromáticas e nas composições coloridas. A partir, dos resultados observou-se que a vegetação densa sofreu uma significativa redução ao longo dos anos e que a vegetação rala e o solo exposto obtiveram um maior crescimento no período analisado.  Desta forma, conclui-se que a degradação da vegetação, ocorreu ao longo dos anos, sendo necessário uma intervenção e plano de recuperação da área.  A vegetação densa teve redução significativa, enquanto houve elevação da vegetação rala. Assim, torna necessário a aplicação de projetos de educação ambiental na comunidade para incentivar a conscientização e preservação desta APP.  Analysis of the degradation of native vegetation in a permanent preservation area in Paraíba A B S T R A C TThe removal of native vegetation to agricultural expansion or for other use, has aggravated the process of forest degradation, causing negative impacts.

Whole genome sequences of SARS-CoV-2 obtained from two patients, a Chinese tourist visiting Rome and an Italian, were compared with sequences from Europe and elsewhere. In a phylogenetic tree, the Italian patient’s sequence clustered with sequences from Germany while the tourist’s sequence clustered with other European sequences. Some additional European sequences in the tree segregated outside the two clusters containing the patients’ sequences. This suggests multiple SARS-CoV-2 introductions in Europe or virus evolution during circulation.

Published: April 2020

A predação é um fator ecológico que regula a vida dos lagartos, entretanto, sua visualização na natureza é esporádica. Quando os predadores são serpentes crípticas, temos registros ainda mais escassos. Aqui nós apresentamos a predação de Tropidurus hispidus (Spix, 1825) pela serpente bicuda Oxybelis aeneus (Wagler in Spix, 1824). Alguns estudos já identificaram lagartos do gênero Tropidurus Wied-Neuwied, 1824 como presas de O. aeneus. No entanto, este registro fornece informações que contemplam importantes aspectos da história natural das duas espécies, contribuindo para a compreensão de suas ecologias.

We have developed specialized equipment based on mini-MDM hydrogen sensors and the WSN telecommunication technology for long-term monitoring of hydrogen content in the environment. Unlike existing methods, the developed equipment makes it possible to carry out measurements directly in the explosion zone with high discreteness in time. This equipment was tested at a large rare-earth deposit of the Lovozero Alkaline Pluton Karnasurt in the underground mining tunnel. We observed a short time very high concentration of hydrogen in the atmosphere (more than 3 orders of normal atmosphere concentration). This discovery is very important because at the time of the explosion one can create abnormally high concentrations of explosive mixtures of hydrocarbon gases that can lead to accidents. The high resolving power of the measurement equipment makes it possible to determine the shape of the anomaly hydrogen of such a concentration and to calculate the volumes of hydrogen released from the rocks, at first time in the practice. The shape of the anomaly usually consists of 2-3 additional peaks of the shape - "dragon-head-like peak". We make an first attempt is made to explain this form of anomaly in the article. The aim of the work in the estimation hydrogen emission in mining ore deposit rare earth elements.

Post-buckling Analysis of Cold-form Steel Column
Authors: Qasim Tuka Mohammed , Al-Zaidee Salah Rohaima
Published: April 2020

For the time being, the cold-formed sections are widely used due to their simple manufacturing and construction processes. To be feasible, the strength of cold-formed columns should be determined based on their post-buckling behavior. Post-buckling relations are cumbersome and need design aids similar to those of American Iron and Steel Institute (AISI) to be applicable. These design aids have been developed to sections and materials other than those available in the local market. Therefore, this paper tries to develop a general finite element model to simulate the postbuckling behavior of cold-formed steel columns. Shell element has been used to discretize the web, flanges, and lips of the column. A linear bucking analysis with subspace Eigen value scheme has been achieved to determine the global, distortional, and local mode shapes. Subsequently, these modes have been used to generate the correspond imperfections. Finally, the modified Riks method has been used to solve the nonlinear equations of equilibrium and to a void the possible snap through phenomenon. Comparing with the traditional analyses using the effective width method and the direct strength method indicates that the finite element analysis is adequate and can be used for practical applications when dealing with local sections and materials.

Finally, different case studies with different column spans have been considered to show the behavior of the column for different slenderness ratios.

Published: April 2020

Many models of psychopathology include a single general factor of psychopathology (GFP) or “p factor” to account for covariation across symptoms. The Adolescent Brain Cognitive Development (ABCD) Study provides a rich opportunity to study the development of the GFP. However, a variety of approaches for modeling the GFP have emerged, raising questions about how modeling choices impact estimated GFP scores. We used the ABCD baseline assessment (ages 9-10 years-old; N=11,875) of the parent-rated Child Behavior Checklist (CBCL) to examine the implications of modeling the GFP using items versus scales; using a priori CBCL scales versus data-driven dimensions; and using bifactor, higher-order, or single-factor models. Children’s rank-ordering on the GFP was stable across models, with GFP scores similarly related to criterion variables. Results suggest that while theoretical debates about modeling the GFP continue, the practical implications of these choices for rank-ordering children and assessing external associations will often be modest.
Counterfactual thoughts distinguish benign and malicious envy
Authors: Crusius Jan , Lange Jens
Published: April 2020

When people encounter others surpassing them in terms of an important quality, possession, or achievement, they often think about what might have happened differently so that they would have obtained a better outcome. Such upward counterfactual thoughts have been shown to contribute to the intensity of envy. We investigated whether specific counterfactual thoughts distinguish different forms of envy, namely benign envy, which entails upward motivation, and malicious envy—which entails hostility. A meta-analysis of eight studies (1 preregistered, N = 1,264) of a first line of research supports that recalled episodes of benign versus malicious envy are characterized by more additive, self-focused counterfactuals or by more other-focused counterfactuals, respectively. Furthermore, a meta-analysis of six studies (1 preregistered, N = 1,299) of a second line of research supports that eliciting these counterfactuals promotes the corresponding form of envy. In line with functional accounts of counterfactual thinking and envy, the results highlight cognitive processes that underlie functionally diverging pathways of envious responding.
Influence of Nitriding and Multiple Peening on Surface Characteristic of Tool Steel AISI D2
Authors: Nambu K. , Nishio M. , Okumiya M. , Miyamoto J.
Published: April 2020

The purpose of this study is to clarify the effect of the combined treatment of nitriding and multi-stage peening on the friction and wear characteristics of tool steel AISI D2. In the measurement of the surface roughness, it was clarified that the size of the dimple changes by the multiple peening treatment when the nitriding treatment is not applied. It was indicated that the surface roughness increased by forming the Sn layer on the surface when the nitriding treatment was performed. It was revealed that the hardness increased significantly by applying multiple peening treatment after nitriding treatment in hardness measurement. In residual stress measurement, it was revealed that residual stress of about −1500 MPa is imparted by multiple peening treatment. In addition, it could be shown that higher residual stress is given after the nitriding treatment. It became obvious the friction coefficient of AISI D2 can be greatly reduced by nitriding multiple peening treatment. In addition, it was clarified that the friction coefficient can be reduced even with only the multiple peening treatment.

Published: April 2020

Additive manufacturing in the powder bed by means of laser powder bed fusion (L-PBF) combines the fast production of metallic components with complex geometrical structures with a high degree of customization and low raw material consumption. However, there is a high demand for the development of new alloys to achieve the desired properties of additively manufactured parts. Due to a lack of knowledge, only a small group of steel powders are currently available for L-PBF. As an example, Cr and CrMn steel powders with additional alloyed nitrogen could be used for L-PBF products for Ni-free medical devices. The present work investigates the possibility of alloying nitrogen to austenitic steel alloy powder and high alloyed martensitic steel powder via gas nitriding. For this purpose, an X30CrMo7-2 powder and an AISI 316L powder for additive manufacturing were arranged to form powder beds of different heights and nitrided at different temperatures, times and nitriding potentials. The nitrogen content was determined from the samples taken at different heights of the powder beds. Individual powder particles were examined by means of metallography, scanning electron microscopy and electron probe micro analysis. It is shown that the nitrogen concentration in the powder is essentially determined by the nitriding temperature. In the X30CrMo7-2 powder, nitride precipitation also occurs at high temperature and N and C gradients are present in the particles with an average nitrogen content of up to 4 mass%. In the 316L powder, a homogeneously distributed nitrogen content of 0.35 mass% can be achieved after gas nitriding at 420 °C for 24 h. The flow properties of both powders are hardly affected by gas nitriding.
Investigation on endurance evaluation of a portal crane: experimental, theoretical and finite element analysis
Authors: Onur Yusuf Aytaç , Gelen Hakan
Published: April 2020

In this study, the stress on portal crane components at various payloads has been investigated theoretically, numerically and experimentally. The portal crane was computer-aided modeled and finite element analyses were performed so that the most stressed points at the each trolley position investigated on the main girder could be determined. In addition, the critical points were marked on the portal crane, and strain gages were attached to the those critical points so that stress values could be experimentally determined. The safety factor values at different payloads were determined by using finite element simulation. Results indicate that the most stressed component in the examined portal crane is the main girder. Experimental results indicate that the maximum stress value on the main girder is 3.05 times greater than the support legs and 8.99 times larger than the rail.

Published: April 2020

Human herpesvirus type 1 (HSV-1), a Alphaherpesvirinae, has a broad range of cross-species infectivity
with considerable variation in expression and disease severity among different hosts. Infection in humans,
results in mild disease characterized by mucocutaneous lesions. In some species of nonhuman primates,
however, the infection can be lethal. Transmission occurs through food contaminated by humans with labial
herpes, offered to monkeys, constituting an important anthropozoonosis. In this study, we describe the
occurrence of two outbreaks of encephalitis caused by HSV-1, occurring in the State of São Paulo, Brazil.
The first outbreak affected a Brown howler monkey and three marmosets. The Brown howler monkey had
tongue ulcers and enteritis and the marmosets were found dead without presenting clinical symptomatology.
The second outbreak affected ten marmosets that were found dead suddenly in the enclosure without
presenting symptoms or clinical signs. Organ fragments were processed for transmission electron
microscopy, histopathology and inoculation in cell culture techniques. Ballooning degeneration, foci of
monolymphocytic inflammatory reaction, corpuscle of eosinophilic inclusion, monolymphocytic meningitis
and desquamative monolymphocytic enterocolitis, were the main lesions observed by histopathology. By
the negative staining technique, enveloped and non-enveloped, herpesvirus particles were found, measuring
120-200 nm in diameter in all samples of organ fragments. The presence of aggregates formed by antigenantibody complex, characterized the positive result obtained in the immunoelectron microscopy technique
for HSV-1. Using the immunocytochemistry technique, the antigen-antibody interaction was strongly
enhanced by the colloidal gold particles over the herpesvirus, confirming the presence of HSV-1.
Intranuclear incomplete particles measuring 80-100 nm in diameter and complete or enveloped scattered in
the cytoplasm, were visualized in ultrathin sections of liver and cell culture measuring 140 nm of diameter.
Immature particles budding from cell membranes were also observed. In viral isolation in VERO cells,
typical cytopathic effect was observed in brain samples.

Published: April 2020

This paper analyses the various issues that influenced the foreign languages
policy in the Swedish school system during the 19th and 20th centuries. In fact,
language teaching has always occupied a dominant place in the Swedish school
system, which remained elitist until the introduction of common compulsory
basic schooling in 1962. Language teaching developed not only with different
school system reforms in response to social transformations, but also with a
succession of foreign influences. The first part of this article examines the
development of the Swedish school system. Then, the status and organization of
language teaching as a whole are analyzed, before examining the three foreign
languages taught : German, French, and English. In conclusion, the article
describes the current state of language teaching in Sweden.

Medical students prefer print textbooks for studying but value the e-books’ search function and availability
Authors: Klein Sabine D.
Published: April 2020

Since a few years our library has mostly acquired journals only in electronic format, whereas medical textbooks are often provided in print and as e-books. In order to meet the students’ current needs and to reasonably allocate financial means and efforts, we performed a survey about format preferences amongst medical students at the University of Zurich, Switzerland. 94 medical students returned our questionnaire in December 2018 (4.6% response rate). The survey showed that print books were used more often, especially for longer reading, but e-books were also commonly used. Perceived advantages of print books were the possibilities to mark text passages and better eye comfort. E-books were valued for their search function and availability.

Authors: Meinisasti Resva , Muslim Zamharira , Krisyanella  , Sunita Raden
Published: April 2020

Background: One of skin diseases that is frequently taking attention among teenagers and young adults is acne or in medical term called acne vulgaris. Acne treatment can be treated by repairing follicular abnormalities, decreasing sebum production, decreasing the number of Propionibacterium acnes colonies and reducing inflammation of the skin. The bacterial population of Propionibacterium acnes can be reduced by giving an antibacterial substance such as erythromycin, clindamycin and benzoyl peroxide. In the treatment of acne we can get antibacterial originating from nature, one of which can be obtained in the secondary metabolism of plants. The extracts and essential oils of betel leaf contain antibacterial and antifungal activities. The effectiveness of the use of betel leaf ethanol extract (Piper betle Linn) in acne treatment can be improved by creating formulations in form of cream preparations. Formulations in cream preparations will affect the amount and speed of active substances that can be absorbed. Objectives: To determine the effectiveness of the ethanol extract cream of betel leaf (piper betle linn) cream in formulas with what percentage of active substance has the most-inhibitory effect on the growth of Propionibacterium acnes. Methods:The study used experimental research. Propionibacterium acnes samples were diluted in 0.9% physiological NaCl sterile and embedded in Nutrient Agar (NA) media. The media was inserted into an incubator at 37 Â° C for 24 hours. The test of antibacterial activity used the disk diffusion method. The antibacterial activity test results were statistically analyzed using the Statistical Product Services Solution (SPSS 17) program with a confidence level of 95% (Î± = 0.05). Results: The three creams containing betel leaf ethanol extracts at percentages of 5%, 10% and 15% for each had inhibitory zones: 9.8 mm, 15.85 mm, 17.35 mm. Conclusion: Cream that contains 15% active substance has the strongest inhibition.

Estágio com Ginástica Laboral: relato de experiência
Authors: Flores Fábio Fernandes , Cotrim Daiane Maria de Jesus , Andrade Daniela da Silva , Souza Luiz Humberto Rodrigues
Published: April 2020

O estágio é configurado como uma das etapas da formação, para tanto é imprescindível que o corpo discente tenha saberes que sustentem suas ações nos campos de atuação do curso. Deste modo o exercício da profissão se faz necessário para que o acadêmico possa ter maiores condições de êxito quando estiver em atividade laboral. O presente trabalho tem por objetivo descrever a vivência do Estágio VI, apontando as facetas da atuação com Ginástica Laboral (GL). Esta experiência se deu a partir do projeto de intervenção desenvolvido na UNEB com os funcionários dos diferentes setores da instituição. O trabalho tem abordagem qualitativa, com caráter descritivo e no formato de relato de experiência. A GL ocorria prioritariamente em seus setores, sendo usado a GL Preparatória e GL compensatória, ambas com duração de 30 minutos. Para coleta dos dados foi usado um roteiro de observação, o diário de bordo e levantamento de informações (similar a anamnese). A avaliação das intervenções ocorreu por meio da roda de conversa. A estrutura física dos setores tinha diferentes dimensões espaciais e espaço de movimentação, mas com ar condicionado e no mínimo: uma mesa ou balcão, duas cadeiras, um computador, um armário. O fato de o estágio ter ocorrido na própria instituição foi possível usar mecanismos distintos para o cumprimento do objetivo. Os participantes fizeram queixas de ordem física e psicológica. Dentre os resultados da intervenção destaca-se a redução das dores, mais disposição e reconhecimento da importância da atividade física. As críticas dos participantes foram à transferência da GL para o final do expediente e aumento da duração da GL. A intervenção do estágio teve importância tripla: na vertente acadêmica, pois contribuiu para que tivéssemos uma experiência formativa com um campo de trabalho; na vertente institucional, por apresentar um cenário talvez desconhecido e ainda revelar uma possibilidade de cuidado para com o funcionário; na vertente dos funcionários, pelo fato de ter oportunizado momentos de redução dos impactos da sobrecarga do trabalho com a GL e ainda o entendimento do quão é necessário ter um estilo de vida saudável.

The existence of labor service company that can not beseparated in the dynamics of development in the Indonesian labor force of restrictionsare clear and precise in the formulation of legislation. Changes in employment status asone of the forms of legal protection of workers' labor service provider is one of therestrictions set by the Government through Act No. 13 of 2003 on Labour in particularlabor relations agreements. Given the setting in Employment Act can not be separatedfrom the basic principles of the agreement, then the restriction that there must still bebased on the basic principles. Protection laws enacted by not considering the basicprinciples of the law will only make the problem more complex labor and potentiallycreates new problems.Keyword :Labor law, work relationship, employment agreement

Mutant IDH1 (mIDH1) inhibitors have shown single-agent activity in relapsed/refractory AML, though most patients eventually relapse. We evaluated the efficacy and molecular mechanism of the combination treatment with azacitidine, which is currently the standard of care in older AML patients, and mIDH1 inhibitor BAY1436032. Both compounds were evaluated in vivo as single agents and in combination with sequential (azacitidine, followed by BAY1436032) or simultaneous application in two human IDH1 mutated AML xenograft models. Combination treatment significantly prolonged survival compared to single agent or control treatment (P<.005). The sequential combination treatment depleted leukemia stem cells (LSC) by 470-fold. Interestingly, the simultaneous combination treatment depleted LSCs by 33,150-fold compared to control mice. This strong synergy is mediated through inhibition of MAPK/ERK and RB/E2F signaling. Our data strongly argues for the concurrent application of mIDH1 inhibitors and azacitidine and predicts improved outcome of this regimen in IDH1 mutated AML patients.

Coronavirus disease-2019 (COVID-19), which started in Wuhan, China, in December 2019 and declared a worldwide pandemic on March 11, 2020, is a novel infectious disease that causes respiratory illness and death. Pediatric COVID-19 accounts for a small percentage of patients and is often milder than that in adults; however, it can progress to severe disease in some cases. Even neonates can suffer from COVID-19, and children may spread the disease in the community. This review summarizes what is currently known about COVID-19 in children and adolescents.

Pathogenesis of adenine-induced chronic renal failure may involve inflammatory, immunological and/or oxidant mechanisms. Gum arabic (GA) is a complex polysaccharide that acts as an anti-oxidant which can modulate inflammatory and/or immunological processes. Therefore, we tested here the effect of GA treatment (15 % in the drinking water for 4 weeks) in plasma and urine of rats, on a novel cytokine that has been shown to be pro-inflammatory, viz, DNA-binding high-mobility group box-1 protein (HMGB1). Adenine (0.75 % in the feed, 4 weeks) significantly increased indoxyl sulphate, urea and creatinine concentrations in plasma, and significantly decreased the creatinine clearance. GA significantly abated these effects. The concentrations of HMGB1 in urine before the start of the experiment were similar in all four groups. However, 24 h after the last treatment, adenine treatment increased significantly the concentration of HMGB1 when compared with the control. GA treatment did not affect the HMGB1 concentration in urine. Moreover, the concentration of HMGB1 in plasma obtained 24 h after the last treatment in rats treated with adenine was drastically reduced compared with the control group. This may explain its significant rise in urine. In conclusion, HMGB1 can be considered a potentially useful biomarker in adenine induced CRF and its treatment.

The origins of scientific thought
Authors: Martin-Merino Mario
Published: April 2020

This study will analyze the origin and development of scientific thought in Antiquity, especiallyin the Greek World, which will largely arise thanks to the doctrines of the so-known as Pre-socratic philosophers, whose reflections and postulates will lay the foundations for a new form of thought that, unlike the one that existed up to that point, was freed from any magical-religious influence with the aim of providing a rational explanation to the different phenomena of nature and of the Universe.

Sea turtles have been proposed as health indicators of marine habitats and carriers of antibiotic-resistant bacterial strains, for their longevity and migratory lifestyle. Up to now, a few studies evaluated the antibacterial resistant flora of Mediterranean loggerhead sea turtles (Caretta caretta) and most of them were carried out on stranded or recovered animals. In this study, the isolation and the antibiotic resistance profile of 90 Gram negative bacteria from cloacal swabs of 33 Mediterranean wild captured loggerhead sea turtles are described. Among sea turtles found in their foraging sites, 23 were in good health and 10 needed recovery for different health problems (hereafter named weak). Isolated cloacal bacteria belonged mainly to Enterobacteriaceae (59%), Shewanellaceae (31%) and Vibrionaceae families (5%). Although slight differences in the bacterial composition, healthy and weak sea turtles shared antibiotic-resistant strains. In total, 74 strains were endowed with one or multi resistance (up to five different drugs) phenotypes, mainly towards ampicillin (~70%) or sulfamethoxazole/trimethoprim (more than 30%). Hence, our results confirmed the presence of antibiotic-resistant strains also in healthy marine animals and the role of the loggerhead sea turtles in spreading antibiotic-resistant bacteria.

Rising life expectancy and the demanding modern lifestyle drive the growing appeal of healthy and balanced diets centered on vegetable and fruit consumption. Functional, phytonutrient-packed and principally raw food is in high demand. Microgreens constitute such a novel functional food that combines a high sensory and bioactive value, which invites comparison to their mature-leaf counterparts. For this purpose, a controlled environment chamber experiment was carried out to compare the mineral, phytochemical and antioxidant capacity attributes of two-pigmented Lactuca sativa L. var. capitata cultivars (green and red Salanova®) harvested at the microgreens and the mature-leaf stage. Macronutrients were assessed through ion chromatography, while carotenoids and polyphenols were assessed and quantified through HPLC-DAD and UHPLC-Q-Orbitrap HRMS, respectively. Calcium and magnesium were higher in microgreens irrespective of the cultivar; conversely, phosphorous, potassium and nitrate where higher in mature leaves. All pigments including chlorophyll, lutein and β-carotene augmented at advanced maturity stage and were more concentrated in the red pigmented cultivar at both stages. Total polyphenols accumulated more densely in red Salanova, particularly in the microgreens stage; whereas, in green Salanova, the accumulation was significant but less pronounced in the mcirogreens stage. Chlorogenic acid, quercetin malonyl glucoside, rutin and coumaroyl quinic acid were the most concentrated phenolic acids in microgreens, while feruloyl tartaric acid was predominant in mature leaves. Finally, when a high carotenoids content is sought, mature lettuce leaves should be the prime culinary choice, whereas high polyphenolic content is dictated by both the cultivar and the harvest stage, with red Salanova microgreens being the most nutrient-packed choice.
