Authors: Prado-Gascó Vicente , Romero-Reignier Virginia , Mesa-Gresa Patricia , Górriz Ana Belén
Published: May 2020

The scale of positive and negative experiences (SPANE) assesses emotional responses and their frequency of manifestation in recent weeks. This scale has been validated in different countries and populations but not in Spanish adolescents. The aim was to evaluate the psychometric properties of SPANE in two samples: (1) Sample I included 797 adolescents (M = 15.5 years old, SD = 0.68, 54.2% female) and, (2) Sample II included 1433 adolescents (M = 13.7 years old, SD = 1.27, 53.2% female). Finally, a subsample from sample II was analyzed in different stages (after six and 12 months) with 298 adolescents (M = 13.7 years old, SD = 1.13, 58.7% female). The results obtained have adequate levels of reliability and validity that seem to justify the use of this diagnostic tool in the Spanish adolescent population.

Published: May 2020

Smart cities follow different strategies to face public health challenges associated with socio-economic objectives. Buildings play a crucial role in smart cities and are closely related to people’s health. Moreover, they are equally essential to meet sustainable objectives. People spend most of their time indoors. Therefore, indoor air quality has a critical impact on health and well-being. With the increasing population of elders, ambient-assisted living systems are required to promote occupational health and well-being. Furthermore, living environments must incorporate monitoring systems to detect unfavorable indoor quality scenarios in useful time. This paper reviews the current state of the art on indoor air quality monitoring systems based on Internet of Things and wireless sensor networks in the last five years (2014–2019). This document focuses on the architecture, microcontrollers, connectivity, and sensors used by these systems. The main contribution is to synthesize the existing body of knowledge and identify common threads and gaps that open up new significant and challenging future research directions. The results show that 57% of the indoor air quality monitoring systems are based on Arduino, 53% of the systems use Internet of Things, and WSN architectures represent 33%. The CO2 and PM monitoring sensors are the most monitored parameters in the analyzed literature, corresponding to 67% and 29%, respectively.
Contextual Modulation in Mammalian Neocortex is Asymmetric
Authors: Kay Jim W. , Phillips William A.
Published: May 2020

Neural systems are composed of many local processors that generate an output given their many inputs as specified by a transfer function. This paper studies a transfer function that is fundamentally asymmetric and builds on multi-site intracellular recordings indicating that some neocortical pyramidal cells can function as context-sensitive two-point processors in which some inputs modulate the strength with which they transmit information about other inputs. Learning and processing at the level of the local processor can then be guided by the context of activity in the system as a whole without corrupting the message that the local processor transmits. We use a recent advance in the foundations of information theory to compare the properties of this modulatory transfer function with that of the simple arithmetic operators. This advance enables the information transmitted by processors with two distinct inputs to be decomposed into those components unique to each input, that shared between the two inputs, and that which depends on both though it is in neither, i.e., synergy. We show that contextual modulation is fundamentally asymmetric, contrasts with all four simple arithmetic operators, can take various forms, and can occur together with the anatomical asymmetry that defines pyramidal neurons in mammalian neocortex.
Modeling Pneumonia-Induced Bloodstream Infection Using Graph Theory to Estimate Hospital Mortality
Authors: Zikos Dimitrios , Athanasopoulou Maria
Published: May 2020

Hospital-acquired pneumonia (HAP) bloodstream infections comprise a major cause of crude hospital mortality. This is a cross-sectional study that used claims data from the Centers for Medicare and Medicaid Services (N = 565,875). The study objective is to represent the progression of pneumonia-induced bloodstream infections using graph theory principles, where each path of the graph represents a different scenario of bloodstream-infection progression, and aims to further estimate the likelihood if hospital death for each path. To disseminate the results, the study makes available a prototype applet to navigate various paths of the graph interactively. Bayesian probabilities were calculated for each scenario, and multivariate logistic regression was conducted to estimate the adjusted OR for inpatient death after controlling for patient age, sex, and comorbidities. The mortality rate ranged from 4.99% for patients admitted with community pneumonia without bloodstream infection and reached 63.18% for cases admitted with bloodstream infection that progressed to hospital septicemia, sepsis, and septic shock. The prototype applet can be used to unfold bloodstream infection events and their associated risk for mortality and could be used in university curricula to assist educators in helping students understand the progression of pneumonia-induced bloodstream infections in a data-driven way.

Published: May 2020

Allergic reactions to stings of Hymenoptera species can have serious or even fatal consequences. If the identification of the culprit insect is possible, venom-specific immunotherapy effectively cures Hymenoptera venom allergies. Although component-resolved diagnostics has strongly evolved in recent years, the differentiation between allergies to closely related species such as Polistes dominula and Vespula spp. is still challenging. In order to generate the basis for new diagnostic and therapeutic strategies, this study aims at resolving the venom proteomes (venomes) of these species. The venoms of P. dominula and Vespula spp. (V. germanica, V. vulgaris) were analyzed by liquid chromatography-mass spectrometry. Resulting proteins were characterized regarding their function, localization and biochemical properties. The analyses yielded 157 proteins in Vespula spp. and 100 in P. dominula venom; 48 proteins, including annotated allergens, were found in both samples. In addition to a variety of venom trace molecules, new allergen candidates such as icarapin-like protein and phospholipase A2 were identified. This study elucidates the venomes of closely related allergy-eliciting Hymenoptera species. The data indicates that relying on marker allergens to differentiate between P. dominula and Vespula spp. venom allergy is probably insufficient and that strategies using cross-reactive major allergens could be more promising.
Modelling the Use of Vaccine and Wolbachia on Dengue Transmission Dynamics
Authors: Ndii Meksianis Z.
Published: May 2020

The use of vaccine and Wolbachia has been proposed as strategies against dengue. Research showed that the Wolbachia intervention is highly effective in areas with low to moderate transmission levels. On the other hand, the use of vaccine is strongly effective when it is implemented on seropositive individuals and areas with high transmission levels. The question that arises is could the combination of both strategies result in higher reduction in the number of dengue cases? This paper seeks to answer the aforementioned question by the use of a mathematical model. A deterministic model in the presence of vaccine and Wolbachia has been developed and analysed. Numerical simulations were presented and public health implications were discussed. The results showed that the performance of Wolbachia in reducing the number of dengue cases is better than that of vaccination if the vaccine efficacy is low, otherwise, the use of vaccine is sufficient to reduce dengue incidence and hence the combination of Wolbachia and vaccine is not necessary.

Published: May 2020

An improved principal component-fuzzy comprehensive assessment coupling model for urban river water quality is proposed, which fully considers the influence of water quality and quantity. This model can not only choose the key indexes, but also specify the spatial variation and class of water quality. This proposed model was used to assess the water quality of the Qingshui and Fenghuang streams in Chongqing, China. Data of twelve indexes used in the assessment were collected from 17 monitoring points. The assessment results show that the key indexes include TN, TP, NH3-N, CODcr, pH, DO and velocity. Water quality of 14 monitoring points is classified as class Bad V, and that of the remaining points is class V. Mainly affected by the deposition of garbage and discharge of domestic sewage, water quality of the midstream is the worst. The upstream is mainly influenced by farmland non-point source pollution and rural domestic sewage pollution. The downstream is close to the scenic area, and environmental control measures such as river dredging and artificial aeration are regularly carried out. The water quality of it is the best. The results provide valuable information that allow local environmental departments to discover the source of pollutant and formulate water resource management strategies.

Published: May 2020

Frequency analysis of extreme events is used to estimate the maximum rainfall associated with different return periods and is used in planning hydraulic structures. When carrying out this type of analysis in engineering projects, the hydrological distributions that best fit the trend of maximum 24 h rainfall data are unknown. This study collected maximum 24 h rainfall records from 362 stations distributed throughout Colombia, with the goal of guiding hydraulic planners by suggesting the probability distributions they should use before beginning their analysis. The generalized extreme value (GEV) probability distribution, using the weighted moments method, presented the best fits of frequency analysis of maximum daily precipitation for various return periods for selected rainfall stations in Colombia.

A Sitcom series to an impeccable articulation – The Role of Technology Journalism in Automobile Industries to obliterate ersatz paradigms
Authors: F Paul Gregory
Published: May 2020

‘Technology Journalism’ is a rarely uttered term, but lives in day to day use, disguised in other forms of journalism. In an era where Sitcom series like ‘Silicon Valley’ (A HBO series which portrays events in the lives of five young men who try to start a tech company) getting quite positive responses from viewers all over the world, it is the necessity of journalists to focus more on technology journalism, rather than making fundamental reviews. Technology journalism must focus not just in reviews about new gadgets in the industry, must also play a key infotainment role. Despite several cherishing moments in this genre, the realm of technology journalism is not a bed of roses. It requires several prerequisites to efficiently carry out technology journalism. In the case of the automobile industry in India, technology journalism needs to be leveraged in a different way. With the market for automobile varying, magazines like Autocar India,  WhatCar?, BiKe India and many more play a major role in taking the evolving technology to the common man. With the interests of common man revolving around lifestyle management, such magazines definitely improve the choice of customers. Hence technology journalism in the automobile industry is crucial. This article drives through fundamental technology journalism for automobile industries highlighting key aspects of the genre. This article has also thrown light into unnecessary paradigms being in practice in technology journalism and also emphasizes on pedagogy and paradigm-free journalism. This article might be ambiguous, but it is necessary to be specific and to achieve a non-agathokakological compose.

Authors: Zulkarnaev TR , Zigitbaev RN , Povargo EA , Kazak AA , Khisamiev II , Gabbasov AZ
Published: May 2020

Background: Over the past decades, the relation between children’s health risks of medical and social factors has changed. In order to determine health effects of some medicosocial factors among primary school children we conducted a questionnaire-based survey of parents in different years. Materials and methods: The studies were conducted in schools of the city of Ufa in the years 2005 and 2017 and included 456 and 465 parents of primary school children, respectively. Results: We established statistically significant relationships between the analyzed medicosocial factors and children’s health. We noticed a decrease in the number of children with the least risk of developing a disease and an increase in the number of children at risk. We also observed some differences between the years of research in adverse health effects of occupational factors in mothers, alcohol consumption by mothers during the perinatal period, and living conditions. Along with the already known risk factors, we found that chronic diseases and tobacco smoking of the father of the unborn child played an important role in the health of schoolchildren. The survey demonstrated that in the year 2017 primary school children spent less time watching television but much more time on the computer than in 2005. Conclusions: A systematic study of medical and social factors is essential for establishing children’s health risk factors and developing appropriate preventive measures. Most risk factors associated with the lifestyle and living conditions are manageable and this fact emphasizes the importance of creating a healthy lifestyle of children and their parents.

Authors: Khramtsov PI , Berezina NO
Published: May 2020

Background: The innovative form of organizing schooling in the mode of dynamic postures providing for alternation of standing and sitting postures at each lesson is implemented in order to prevent detrimental health effects of the long-term stationary sitting posture, reduce static and educational fatigue, preserve and strengthen health in educational institutions. Our objective was to assess the health status of primary school children studying in dynamic postures. Materials and methods: We assessed the health status of 174 pupils aged 7–10 in the first to third grades of primary school studying in the mode of dynamic postures. The health data was obtained from their personal medical records. The assessment was carried out in accordance with the comprehensive methodology for assessing health of children and adolescents based on the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. Physical development was measured using regression scales. Results: We established that visual impairment (137.9‰) and musculoskeletal disorders (109.2‰) ranked highest in the structure of functional disorders (FD) among the first to third graders. The prevalence of functional disorders of the circulatory and respiratory system was 86.2‰ and 80.5‰, respectively. Musculoskeletal conditions dominated in the structure of chronic diseases (63.0%), the prevalence being 293.1‰. These were followed by diseases of the skin and subcutaneous tissue and gastrointestinal diseases with the prevalence rate of 46.0‰ each. The total prevalence of functional abnormalities among the primary school first to third graders was 500.0‰ while the prevalence rate of chronic diseases was 465.5‰. Normal physical development was observed in 82.9% of the subjects. Overweight and obesity were detected in 11% and 0.6% of the children, respectively, while underweight, small and big height were measured in 3.1%, 1.8%, and 0.6% of the children, respectively. Conclusions: The comparative data analysis helped establish lower disease prevalence rates among the children studying in dynamic postures compared to those studying in the seated position. Our findings may serve as a scientific substantiation of efficiency of using the dynamic posture regime in order to maintain and improve health of schoolchildren.
Health Risks for the Population of the Voronezh Region Related to Drinking Water Quality
Authors: Mehantiev II
Published: May 2020

The object of the study was the centralized drinking water supply system of the Voronezh Region. The purpose of the study was to assess health risks for the population of the Voronezh Region associated with drinking water quality.
Materials and methods: The data of the regional drinking water quality monitoring system, which included monthly sampling and testing of water samples at 553 sites in 32 administrative districts and the city of Voronezh for 8 priority sanitary and chemical indicators (total hardness, concentrations of iron, manganese, nitrates, nitrites, boron, fluorine, and ammonium ions) for the years 2010-2019 were used. To achieve the objective based on monitoring studies of drinking water quality in the water distribution system, four generally accepted stages of risk assessment were implemented including hazard identification, evaluation of dose-response relationship, exposure assessment, risk quantification and characterization. When evaluating the exposure, four calculation scenarios were considered and probable body burdens for children and adults were calculated using the average long-term concentration and 95 percentile of concentration in a separate administrative territory. Results: Regional non-carcinogenic risks estimated on the basis of the average regional concentrations of priority pollutants did not exceed acceptable values (HQ < 1) for 6 of 7 ingredients. Unacceptable risk levels were observed in two of 33 administrative districts due to the presence of nitrates in drinking water (HQ ranged 1.34 to 2.95 for children and equaled 1.26 for adults). Detailed information for separate settlements (control points) using an aggravated scenario helped identify 4 rural settlements in 2 administrative districts with unacceptable risks for the child population of iron in drinking water (HQ up to 2.31), 230 settlements in 27 districts – of nitrates (HQ up to 9.51), one settlement – of boron (HQ = 1.17), and 35 settlements in 13 districts – of fluorine (HQ up to 4.17). Discussion: Summarizing the results of the regional studies of health risks for the population associated with the quality of drinking water, one can testify the shift of the problem to rural settlements where water treatment is practically null. The use of average concentrations of chemicals in drinking water in administrative districts proved to be insufficiently objective and having significant uncertainties. The reduction of uncertainties was achieved by a detailed review of the information for each monitoring site and the use of the 95th percentile concentration of the chemical to assess the health risks for children and adults. Conclusions: With a sufficient degree of certainty, the priority regional indicators determining the unacceptable level of non-carcinogenic risk (HQ > 1) associated with the quality of drinking water include elevated levels of nitrates, fluorine, boron, and iron.
Key words: drinking water, centralized water supply, water quality, public health risk.
The Lack of First Aid Skills as a Contributing Factor of High Road Traffic Fatality Rates
in the Russian Federation
Authors: Popov AV , Kaimakova UM , Stetsky NP , Rebro IV , Mustafina DA
Published: May 2020

Background: The Russian Federation is among the countries with the highest road traffic fatality rates in the WHO European Region. One of the main reasons for that is the personal attitude of traffic participants to safety that includes medical illiteracy and unpreparedness to render first aid to the injured. Our objective was to study failure to give quick and competent first aid as one of the possible causes of road traffic deaths in the Russian Federation and to identify potential ways of improving the situation. Materials and methods: In May-September 2018, in January and June 2019, we conducted a survey of 403 Russian citizens (284 men and 119 women) having a driver’s license and driving experience in different Russian regions including the Volgograd Region, the Krasnodar Krai, the Rostov Region, Moscow, etc. The respondents were asked to answer the questions about first aid training courses in driving schools, prior involvement in road traffic accidents, and first aid techniques. Results: Most of the respondents (63%) reported having had first aid training courses at driving schools given by driving instructors and almost a quarter of the respondents (23%) reported having never had such courses at all. Approximately 68% of the survey participants had no first aid training using dummies. About 17% witnessed traffic collisions and provided at least some level of first aid while almost 14% could not give any help due to the stressful situation or fear to do harm to the injured. We then calculated the number of correct and complete answers rated 1 and 2 points according to the estimation scale and drew a control chart of the average value. The analysis of the control chart showed that 331 of 403 participants (82%) passed our test. Conclusions: Although the results were not as bad as might have been expected, significant gaps in basic first aid knowledge did exist: some respondents failed to answer the questions correctly. Given that in addition to theoretical knowledge the person should be able to use this knowledge decisively and calmly, without panic and the fear of blood, the percentage of those who can really help is even lower. First aid training courses in driving schools shall be mandatory and must be given by medical professionals. Governmental regulatory authorities should pay special attention to this issue when licensing. At the same time, more emphasis should be placed on first aid training in educational institutions (kindergartens, schools, colleges, and universities). In addition, we recommend compulsory first aid training of professional drivers of commercial vehicles.

Published: May 2020

Introduction: The excessive use of electronic devices may induce visual impairment. Our objective was to get and analyze a subjective evaluation of effects of digital devices on vision with account for hygienic principles of protecting the eyesight based on the results of an online survey of 568 students from Russia and Belarus. Material and methods: We conducted an online questionnaire survey of 498 university students from the Russian Federation and 70 students from the Republic of Belarus to analyze their subjective evaluation of the impact of behavioral risk factors on health and vision. Results: More than half (53.9%) of the respondents rated their health as “good” and 28.3% as “satisfactory”. Vision was considered “excellent” by 25.9% of the respondents while 22.5%, 26.8%, and 24.8% of the students assessed their vision as “good”, “satisfactory”, and “bad”, respectively. The average subjective vision risk values ranged from 6 to 8 points. The majority of the respondents reported that the main sources of information about eyesight protection included the Internet (80%) and the opinion of teachers (70%) and medical workers (67%). Conclusions: The students adequately assessed both health and vision risks of behavioral factors. Yet, good awareness of the damaging effect of digital devices on eyes did not influence the temptation of their use in adverse conditions for the eyesight. We identified a risk group including almost 30% of the respondents characterized by a careless attitude to health and neglect of hygienic principles of eyesight protection. University teachers should take into account the fact that students consider their opinion to be significant for the development of health-saving competencies of young people.
Remote Sensing of the Earth as a Method of Assessing Environmental Quality of Urban Areas
Authors: Yeprintsev S.A. , Klepikov O.V. , Shekoyan S.V.
Published: May 2020

Introduction: Spatial zoning of an urban area by the level of anthropogenic burden using land-based research methods is very time-consuming. Since the end of the 20th century, the usage of the Earth remote sensing (ERS) techniques has served as their more efficient alternative. The study objectives included geoinformation zoning and evaluation of the level of technogenic changes in the areas according to NDVI (Normalized Difference Vegetation Index) values. Materials and methods: The cities of the Voronezh Region and their suburban ten-kilometer territories were chosen as the study objects. For the spatial analysis of the area of anthropogenically modified territories based on the example of the cities of the Voronezh Region we created an archive of multichannel satellite images taken by the Landsat-7 and Landsat-8 satellites. The data were borrowed from the Website of the US Geological Survey. Space images were grouped by two periods (the years of 2001 and 2016). Depending on NDVI values, territories with high and low anthropogenic burden, natural framework zones, and water bodies were distinguished. Results: We established that the smallest percentage of areas of the natural framework and their poor location was observed in the city of Voronezh. The largest area occupied by the natural framework was identified within the town of Borisoglebsk. This fact is attributed to the sensible policy of ensuring environmental and hygienic safety of the population implemented by the regional and municipal authorities. Discussion: At present, it is still impossible to fully use space monitoring data to assess health risks of technogenic factors; they can only be used simultaneously with ground monitoring that includes instrumental and laboratory monitoring of environmental quality indicators within the framework of the socio-hygienic monitoring. Conclusions: The analysis of changes in the proportion of areas with a high anthropogenic burden relative to the natural framework performed using satellite images taken in 2001 and 2016 showed an increase in the technogenic burden on the urban environment.

of Female Greenhouse Workers during the Work Shift
Authors: Yatsenko LA , Mamchik NP , Gabbasova NV
Published: May 2020

Introduction: The number of greenhouse vegetable businesses has been increasing recently. Most tasks in the greenhouses are still done manually and associated with physical stress. Our objective was to study characteristics of the circulatory and muscular systems of female greenhouse workers in the course of their work and depending on the length of service at the enterprise. The materials included some indices of the functional state of the organism of greenhouse workers growing vegetables such as the heart rate, systolic and diastolic blood pressure, muscle strength and endurance of the right hand in the process of harvesting and removing plant debris. The statistical data processing was performed using the Microsoft Excel 2016 software. The results of the study showed that the work of greenhouse vegetable growers caused gradual changes in the functioning of the cardiovascular and neuromuscular systems of the body. The most significant increase in the heart rate and blood pressure and the decrease in muscle strength and endurance were observed among the greenhouse workers with 15 or more years of work experience. We also observed a significant decrease in muscle strength of the right hand among the workers with the shortest record of service (< 5 years). The study of the functional state of the cardiovascular and muscular systems helped establish the most potentially efficient group of greenhouse vegetable growers: the smallest fluctuations of the measured indices were observed in the women with 6-9 years of service. Conclusions: Our findings prove the necessity of systematic science-based measures of disease prevention in female greenhouse employees.

O caldo-de-cana é uma bebida obtida do esmagamento da cana-de-açúcar através de moendas, geralmente acrescido de gelo e frutas cítricas, muito apreciado pelos consumidores e, geralmente, comercializada em feiras livres e por ambulantes em vias públicas. Para que a obtenção do caldo-de-cana seja feita de forma segura é fundamental a adoção de Boas Práticas relacionada com o beneficiamento, preparo, armazenamento e distribuição da bebida. Esse trabalho teve como objetivo quantificar matérias estranhas e sujidades totais em amostras de caldo-de-cana comercializadas em Sete Lagoas-MG. Foram coletadas 21 amostras da bebida e analisadas pelo método de filtração direta, seguido de observações em microscópio estereoscópio e microscópio ótico acoplados com câmera digital. Do total de amostras analisadas, 61,9% apresentaram matérias estranhas indicativas de falhas de boas práticas e 14,3% apresentaram matérias  estranhas indicativas de riscos à saúde humana. Com relação às análises físico-químicas, verificou-se que a acidez expressa em ácido cítrico variou de 0,05 a 0,18%, o pH de 5,5 a 6,17 e o teor de sólidos solúveis de 16,4 a 28,6° Brix. Pode-se concluir que apenas 23,8% estavam adequadas para consumo. As principais falhas verificadas no momento da coleta que podem explicar tal contaminação foram a exposição da cana-de-açúcar no ambiente com presença de vetores, falta de proteção para cabelos dos manipuladores, bem como o contato das roupas do manipulador com a matéria-prima e o descarte incorreto dos resíduos sólidos gerados no processamento.

O turismo ecológico tem se mostrado capaz de melhorar o entendimento da população acerca dos benefícios da conservação ambiental. Para que isso seja feito, é necessário dar condições adequadas ao visitante, de maneira que a experiência vivida seja a melhor possível. Neste sentido, a gestão de unidades de conservação passa pelo planejamento minucioso acerca dos melhores períodos para visitação. Assim, objetivou-se analisar o Índice de Vegetação por Diferença Normalizada para a APA do Rio Pandeiros de modo a contribuir para o planejamento do ecoturismo no local. Foram consideradas imagens do satélite Landsat-8 obtidas mensalmente entre agosto de 2016 e agosto de 2018. Os dados foram processados utilizando-se o software QGis e os resultados foram correlacionados com o regime pluviométrico da região. Foi possível observar uma estreita relação entre a condição da vegetação e a quantidade de chuva ocorrida. Para o período de junho a outubro, há maior concentração de vegetação mais esparsa e para os meses de dezembro até abril há maior concentração de vegetação densa, nos dois períodos analisados. Conclui-se que é possível utilizar o índice de vegetação por diferença normalizada para indicar períodos de visitação turística no local, permitindo um planejamento de viagem que atenda as demandas do visitante em relação às cenas paisagísticas que serão contempladas.

O impacto provocado por afídeos e mosca-branca, tem crescido consideravelmente nas últimas décadas, devido ao aumento nos casos de surtos populacionais destas pragas que são transmissoras de vírus em diversas culturas de importância econômica. A aquisição e a transmissão da maioria dos vírus fitopatogênicos por um inseto vetor é o ponto central para o ciclo de uma infecção. Os vírus de plantas podem interagir com seus hospedeiros de insetos em uma variedade de formas, em alguns casos inclusive a replicação do vírus pode ocorrer em células do inseto. A interação do vírus com seus inseto hospedeiro/vetor requer interações moleculares específicas entre vírus e hospedeiro, comumente via proteínas, no entanto, quais componentes do vetor estão envolvidos e como eles funcionam para facilitar a transmissão ainda não está bem entendido. O objetivo do presente trabalho foi realizar uma revisão sistemática sobre as relações básicas de vírus/vetor em afídeos e mosca-branca; mostrar as práticas utilizadas atualmente no manejo integrado de pragas para afídeos e mosca-branca, além disso, relatar como as interações vetoriais de inseto estão abrindo novas portas para o controle de insetos vetores de vírus de plantas com o uso de novas tecnologias genéticas e computacionais. O presente estudo seguiu a metodologia de revisão sistemática, o trabalho foi conduzido em etapas que envolveram o desenvolvimento do protocolo de revisão com as questões da pesquisa, a estratégia de busca, a identificação dos critérios de inclusão e exclusão, a busca nas bases de dados previamente definidas, avaliação crítica, extração dos dados relevantes e síntese. A identificação dos artigos foi realizada na base de dados PUBMED www.ncbi.nlm.nih.gov/pubmed/. Foi concluído que é necessário aliar o uso de novas tecnologias como o RNAi com as ferramentas já utilizadas no manejo integrado de pragas para uma maior efetividade do controle de pulgão e mosca-branca, contudo, o contínuo estudo e aplicação de novas tecnologias moleculares na investigação de interações vírus-vetor fornecerá maior ajuda no controle das doenças virais de plantas disseminadas por pulgão e mosca-branca no futuro.

The centrifugation of samples is frequently required in laboratory analysis, whether be it for chemical, physical or biological analysis of soil. The software Centrifuge 1.0 is a simple tool available that enable researchers to quantify the energy applied to samples during the centrifugation process. This study aims to demonstrate the new option of calculus incorporated into the software, such as sedimentation of particles in fluids in the centrifuge and analyses the deviation on outputs caused by variations in the values of the parameters used. In its 2.0 version, the Centrifuge software is more useful in carrying out laboratory techniques, because it can be applied to quantify energy in samples or sedimentation of solids particles in fluids during the centrifugation process. The software Centrifuge 2.0 is freely available and can be obtained with the authors.

No Brasil, alguns dos índices utilizados na avaliação da difusão da ciência são: o índice Qualis, os índices h, g e h normalizado além do fator de impacto e sua versão proprietária o JCR. Este artigo tem por objetivo avaliar o impacto e a qualidade dos periódicos da área de Ciências Agrárias I da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), no período de 2010 a 2016. Essa avaliação se deu a partir de diversos vieses, sendo que para alguns puderam ser analisadas todas as 3975 revistas (censo) e, para outros, uma amostra de 748 revistas. Foram avaliados o Qualis, citações por artigo, número de artigos publicados, número de autores por artigo, índice g, índice h, índice h individual normalizado (hinorm), número de citações, número de artigos, fator de impacto (FI) e JCR (Jornal Citation Reports). Os dados referentes ao Qualis foram obtidos da plataforma Sucupira da Capes, enquanto as demais variáveis foram coletadas a partir do software Harzing’s Publish or Perish. O tratamento estatístico e a tabulação dos dados foram feitas no software estatístico R e no software Excel, respectivamente. Os resultados apontam que existe uma correlação positiva entre todas as métricas de impacto supramencionadas e uma correlação baixa do Qualis com as outras métricas de avaliação da produção científica.

A sociedade torna-se cada vez mais consciente em relação às externalidades apresentadas pela agricultura convencional, assim, a demanda por sistemas que degradem menos o meio ambiente é crescente. Neste contexto, objetivou-se caracterizar o desempenho agronômico do milho em solo adubado com diferentes adubações orgânicas. O delineamento experimental foi em blocos aleatorizados 5 tratamentos e 15 repetições, totalizando 75 unidades experimentais. Os tratamentos foram: testemunha (sem adubo); esterco bovino (40 t ha-1); esterco aviário (5 t ha-1); esterco caprino (65 t ha -1) e misto (bovino+aviário+caprino) (36 t ha-1). Aos 14, 21, 28 e 35 dias após o plantio (DAP) foi mensurada a altura da planta, número de folhas e diâmetro do colmo; a altura da primeira espiga no colmo aos 80 DAP. Os resultados demonstram que para os caracteres avaliados, os menores valores foram observados no tratamento com esterco bovino. A adubação mista proporcionou aumento no número de folhas. O esterco de caprinos promoveu maior diâmetro do colmo e número de espiga/planta. O peso da espiga/planta foi incrementado com o uso do esterco caprino e do esterco misto.
