Classification of Wetland Vegetation Based on NDVI Time Series from the HLS Dataset
Authors: Ju Yang , Bohrer Gil
Published: April 2022

Natural wetlands are intrinsically heterogeneous and typically composed of a mosaic of ecosystem patches with different vegetation types. Hydrological and biogeochemical processes in wetlands vary strongly among these ecosystem patches. To date, most remote sensing classification approaches for wetland vegetation either rely on coarse images that cannot capture the spatial variability of wetland vegetation or rely on very-high-resolution multi-spectral images that are detailed but very sporadic in time (less than once per year). This study aimed to use NDVI time series, generated from NASA’s HLS dataset, to classify vegetation patches. We demonstrate our approach at a temperate, coastal lake, estuarine marsh. To classify vegetation patches, a standard time series library of the four land-cover patch types was built from referencing specific locations that were identified as “pure” pixels. These were identified using a single-time high-resolution image. We calculated the distance between the HLS-NDVI time series at each pixel and the “pure”-pixel standards for each land-cover type. The resulting true-positive classified rate was >73% for all patch types other than water lily. The classification accuracy was higher in pixels of a more uniform composition. A set of vegetation maps was created for the years 2016 to 2020 at our research site to identify the vegetation changes at the site as it is affected by rapid water elevation increases in Lake Erie. Our results reveal how changes in water elevation have changed the patch distribution in significant ways, leading to the local extinction of cattail by 2019 and a continuous increase in the area cover of water lily patches.

Semiconductor photocatalysis is considered to be a promising technique to completely eliminate the organic pollutants in wastewater. Recently, S-scheme heterojunction photocatalysts have received much attention due to their high solar efficiency, superior transfer efficiency of charge carriers, and strong redox ability. Herein, we fabricated an S-scheme heterostructure BiOCl/MoSe2 by loading MoSe2 nanosheets on the surface of BiOCl microcrystals, using a solvothermal method. The microstructures, light absorption, and photoelectrochemical performances of the samples were characterized by the means of SEM, TEM, XRD, transient photocurrents, electrochemical impedance, and photoluminescence (PL) spectra. The photocatalytic activities of BiOCl, MoSe2, and the BiOCl/MoSe2 samples with different MoSe2 contents were evaluated by the degradation of methyl orange (MO) and antibiotic sulfadiazine (SD) under simulated sunlight irradiation. It was found that BiOCl/MoSe2 displayed an evidently enhanced photocatalytic activity compared to single BiOCl and MoSe2, and 30 wt.% was an optimal loading amount for obtaining the highest photocatalytic activity. On the basis of radical trapping experiments and energy level analyses, it was deduced that BiOCl/MoSe2 follows an S-scheme charge transfer pathway and •O2−, •OH, and h+ all take part in the degradation of organic pollutants.
Optimized Distributed Proactive Caching Based on Movement Probability of Vehicles in Content-Centric Vehicular Networks

Published: April 2022

Content-centric vehicular networks (CCVNs) have considered distributed proactive caching as an attractive approach for the timely provision of emerging services. The naïve caching schemes cache all of the contents to only one selected roadside unit (RSU) for requested vehicles to decrease the data acquisition delay between the data source and the vehicles. Due to the high deployment cost for RSUs and their limited capacity of caching, the vehicular networks could support only a limited number of vehicles and a limited amount of content and thus decrease the cache hit ratio. This paper proposes a mobility-aware distributed proactive caching protocol (MDPC) in CCVNs. MDPC caches contents to the selected RSUs according to the movement of vehicles. To reduce the redundancy and the burden of caching for each RSU, MDPC distributes to cache partial contents by the movement pattern, the probability to predict the next locations (RSUs) on the Markov model based on the current RSU. For recovery of prediction failures, MDPC allows each RSU to request partial missing contents to relatively closer neighbor RSUs with a short delay. Next, we expand the protocol with traffic optimization called MDPC_TO to minimize the amount of traffic for achieving proactive caching in CCVNs. In proportion to the mobility probability of a vehicle toward each of the next RSUs, MDPC_TO controls the amount of pre-cached contents in each of the next RSUs. Then, MDPC_TO has constraints to provide enough content from other next RSUs through backhaul links to remove the delay due to prediction failures. Simulation results verify that MDPC_TO produces less traffic than MDPC.

Published: April 2022

Teleoperation robot systems can help humans perform tasks in unstructured environments. However, non-intuitive control interfaces using only a keyboard or joystick and physiological tremor reduce the performance of teleoperation. This paper presents an intuitive control interface based on the wearable device gForcePro+ armband. Two gForcePro+ armbands are worn at the centroid of the upper arm and forearm, respectively. Firstly, the kinematics model of the human arm is established, and the inertial measurement units (IMUs) are used to capture the position and orientation information of the end of the arm. Then, a regression model of angular transformation is developed for the phenomenon that the rotation axis of the torsion joint is not perfectly aligned with the limb segment during motion, which can be applied to different individuals. Finally, to attenuate the physiological tremor, a variable gain extended Kalman filter (EKF) fusing sEMG signals is developed. The described control interface shows good attitude estimation accuracy compared to the VICON optical capture system, with an average angular RMSE of 4.837° ± 1.433°. The performance of the described filtering method is tested using the xMate3 Pro robot, and the results show it can improve the tracking performance of the robot and reduce the tremor.
Research on Fuel Offset Control of High-Pressure Common-Rail Diesel Engine Based on Crankshaft Segment Signals
Authors: Wang Yuhua , Wang Guiyong , Yao Guozhong , Shen Lizhong
Published: April 2022

This paper studies the fuel supply offset of diesel engines based on the crankshaft segment signal. Engine nonuniformity refers to the crankshaft torque fluctuation caused by cylinder-to-cylinder differences caused by misfiring or differences in the fuel supply or air supply. Fuel injection offset can reduce the nonuniformity between cylinders to realize high-efficiency and low pollution combustion. Based on crankshaft segment signal characteristics, an individual cylinder fuel offset control (FOC) strategy was built. The high-pressure common-rail diesel engine operating nonuniform control strategy was put forward. Based on crankshaft segment signal characteristics at different operating conditions, the reasonable operating condition of detecting the engine individual cylinder nonuniform degree was put forward. The open-loop and closed-loop control mode based on the condition was set up. The proportional-integral (PI) control algorithm is proposed to quantify engine individual cylinder nonuniform degree, and the fuel amount offset value was obtained. According to the principle of FOC, based on the automotive electronics development ASCET software platform, the FOC strategy module of the electronic control unit (ECU) was designed, and the simulation experiment was carried out. Research shows that for Z cylinder engine, just the first Z/2 harmonic components below fire frequency can fully reflect the state of the engine’s nonuniform operation. The control target to individual cylinder FOC is zero for the synthetic waveform amplitude of the first Z/2 harmonic components. Compared with the traditional quantization method, the fuel offset information extracted from the crankshaft segment signal has stronger anti-interference and more accurate parameters. FOC algorithm can accurately reflect the engine’s operating nonuniformity. The control of the nonuniformity is reasonable. The offset fuel amount calculated by FOC is very consistent with the fuel supply state of each cylinder set by the experiment, which meets the requirement of accurate fuel injection control of the diesel engine.

Background: Previous research has explored associations between accelerometry and Global Navigation Satellite System (GNSS) derived loads. However, to our knowledge, no study has investigated the relationship between these measures and a known distance. Thus, the current study aimed to assess and compare the ability of four accelerometry based metrics and GNSS to predict known distance completed using different movement constraints. Method: A correlational design study was used to evaluate the association between the dependent and independent variables. A total of 30 physically active college students participated. Participants were asked to walk two different known distances (DIST) around a 2 m diameter circle (small circle) and a different distance around an 8 m diameter circle (large circle). Each distance completed around the small circle by one participant was completed around the large circle by a different participant. The same 30 distances were completed around each circle and ranged from 12.57 to 376.99 m. Instrumentation: Acceleration data was collected via a tri-axial accelerometer sampling at 100 Hz. Accelerometry derived measures included the sum of the absolute values of acceleration (SUM), the square root of the sum of squared accelerations (MAG), Player Load (PL), and Impulse Load (IL). Distance (GNSSD) was measured from positional data collected using a triple GNSS unit sampling at 10 Hz. Results: Separate simple linear regression models were created to assess the ability of each independent variable to predict DIST. The results indicate that all regression models performed well (R = 0.960–0.999, R2 = 0.922–0.999; RMSE = 0.047–0.242, p < 0.001), while GNSSD (small circle, R = 0.999, R2 = 0.997, RMSE = 0.047 p < 0.001; large circle, R = 0.999, R2 = 0.999, RMSE = 0.027, p < 0.001) and the accelerometry derived metric MAG (small circle, R = 0.992, R2 = 0.983, RMSE = 0.112, p < 0.001; large circle, R = 0.997, R2 = 0.995, RMSE = 0.064, p < 0.001) performed best among all models. Conclusions: This research illustrates that both GNSS and accelerometry may be used to indicate total distance completed while walking.

Authors: Ceccarini Chiara , Mirri Silvia , Prandi Catia
Published: April 2022

The increase of smart buildings with Building Information Modeling (BIM) and Building Management Systems (BMS) has created a large amount of data, including those coming from sensors. These data are intended for monitoring the building conditions by authorized personnel, not being available to all building occupants. In this paper, we evaluate, from a qualitative point of view, if a user interface designed for a specific community can increase occupants’ context-awareness about environmental issues within a building, supporting them to make more informed decisions that best suit their needs. We designed a user interface addressed to the student community of a smart campus, adopting an Iterative Design Cycle methodology, and engaged 48 students by means of structured interviews with the aim of collecting their feedback and conducting a qualitative analysis. The results obtained show the interest of this community in having access to information about the environmental data within smart campus buildings. For example, students were more interested in data about temperature and brightness, rather than humidity. As a further result of this study, we have extrapolated a series of design recommendations to support the creation of map-based user interfaces that we found to be effective in such contexts.
Analysis of the Driving Force of Land Use Change Based on Geographic Detection and Simulation of Future Land Use Scenarios
Authors: Wu Fengqiang , Mo Caijian , Dai Xiaojun
Published: April 2022

Land use and land cover changes (LULCC) are the result of the combined action of many influencing factors such as nature, society, economy and politics. Taking Chongqing as an example, the driving factors of urban land expansion in Chongqing from 1999 to 2019 are analyzed using a geographic detection (GD) method. Based on this analysis, a land use scenario of Chongqing in 2029 is simulated by an Artificial Neural Network-Cellular Automata model. The results of the analysis of factors affecting land use change show that five factors have a significance >0.05: population, distance from central city, school density, GDP and the distance from railway, showing that these factors have a high impact on LULCC in Chongqing. In addition, the results of risk detection analysis show that areas with a population >50/km2; the areas with a distance <200 km from the city center; areas with a school density >5/km2; areas with a high GDP; and areas with a distance <25 km from the railway have a greater impact on urban land use change than other areas. The land use scenario in 2029 also is simulated based on the land use situation in 2019. The predicted results clearly reflect a land use change trend of increasing urban land and decreasing agricultural land in the region. These land use changes are especially related to the expansion of the population, economy, roads, and schools in the process of urbanization. This analysis also shows that the GD-ANN-CA model developed in this paper is well suited to urban land use simulation.

Published: April 2022

The aim of this study was to examine differences in achievement motivation (measured with the Objective Achievement Motivation Test, OLMT, Schuhfried®) and competitiveness between male and female semi-professional football players. The OLMT objectively assessed three constructs regarding achievement motivation: motivation through personal goals, aspiration level, and motivation through competition. In addition, competitiveness was measured with the self-reported Competitiveness-10 Questionnaire. Finally, participants’ performance was assessed by three expert observers in each of ten matches. Thirty-eight football players (men = 27; women = 11) participated in the present study, and no significant differences were found in the Levene test when comparing men and women with respect to the scores obtained in the different measures used in our research. Significant differences were found in the motivation through competition (p = 0.021) as well as in self-reported competitiveness (p = 0.020) as a function of gender, with males showing higher values in both cases. No gender differences were found in aspiration level (p = 0.283) or motivation through personal goals (p = 0.897). Moreover, age and player performance did not modulate gender differences on any measures. No significant correlation was found between motivational measures and performance. In conclusion, it should be noted that the only variable on which gender differences emerged was the level of competitiveness, such that males scored higher than females on both objective and self-reported measures.

Published: April 2022

Background: The Yangtze River Economic Belt (YREB) occupies an important economic position in China and has great research value. Methods: Based on the panel data of 142 GEM-listed companies in the YREB from 2015 to 2019, using the DEA Malmquist index, σ-convergence and β-convergence models, this study empirically analyzes the dynamic change and convergence trend of the innovation efficiency of these companies. Results: The number of these companies increased significantly but the innovation efficiency of them has not reached the optimal level. From a static point of view, companies in the middle reaches of the Yangtze River have the highest innovation efficiency, while from the dynamic point of view, the Yangtze River Delta region has the highest innovation efficiency. Moreover, most companies have an agglomeration effect, and there is a big gap in innovation efficiency. There is no σ-convergence trend in the YREB and its sub-regions, but there is an obvious β-convergence trend. Conclusions: The innovation efficiency of these companies has a lot of room for improvement. There is industry heterogeneity, and exogenous factors have different effects on the improvement of innovation efficiency in different regions owing to the differences in geographical location, economic development level, and other factors.

Published: April 2022

Electric vehicle (EV) loads are playing an increasingly important role in improving the flexibility of power grid operation. The prerequisite for EV loads to participate in demand response (DR) is that the DR regulation strategy and corresponding DR potential must be accurately analyzed and evaluated. However, due to the uncertainty and differences in travel and charging behavior, DR potentials of EVs exhibit randomness and differ in time and space. In addition, it is difficult to obtain refined travel data and charging load data of large-scale EVs. Accordingly, this paper focuses on how to consider the various influencing factors of potential, and realize the quantitative evaluation of DR time-varying potential of an EV group based on small sample data. First, a travel activity model of the EV is established. Based on the actual travel data, the probability distributions of the key parameters of the travel model are obtained by kernel density estimation and probability statistical fitting. Then, combined with the charging behavior model, and based on Monte Carlo simulation, the load curve of the EV in a residential area is predicted. Considering the travel need of the EV, the peak-shaving potential, vehicle-to-grid discharge potential, and valley-filling potential of the EV under different DR strategies are calculated and analyzed, and the time-varying characteristics of the potential are analyzed. Finally, a case study is carried out with the actual data. The results show that the DR time-varying potential under different time periods and control strategies can be effectively evaluated. The maximum peak-shaving potential of 1000 EV aggregates is 2.7 MW, and the minimum is 0.25 MW. The maximum valley-filling potential is 2.1 MW, and the minimum is 0.3 MW. The research results can provide effective guidance for EVs to participate in day-ahead scheduling, and for the screening of target EVs.

Methyl violet 2B dye is a major contaminant that is detrimental to both humans and aquatic microorganisms, thus it should be eliminated from water. In the current investigation, the biosorption of methyl violet 2B dye onto the brown seaweed Cystoseira tamariscifolia biomass as a sustainable low-cost biosorbent was examined by varying biosorption parameters. Biomass dosage of 7 g/L, pH 6, a temperature of 45 °C, a 60 min contact time, and a 30 mg/L initial dye concentration were determined to be the optimum biosorption conditions. Data obtained were interpreted by thermodynamic, isothermal, and kinetic models. The thermodynamic studies demonstrated that the process of dye biosorption was random and endothermic. The data were best described by Langmuir, Dubinin–Radushkevich, and Temkin models. According to the Langmuir equation, the maximal biosorption capacity (qmax) was 10.0 mg/g. Moreover, the pseudo-second-order mechanism is dominant, and chemical biosorption might represent the rate-controlling stage in the biosorption process. However, intraparticle diffusion revealed a boundary layer effect. A scanning electron microscope, energy-dispersive X-ray spectroscopy, the point of zero charge, and Fourier Transform Infra-Red were applied to characterize the algal biomass, exhibiting its remarkable structural properties and the availability of several functional groups. Additionally, ion exchange, electrostatic force, and hydrogen bonding formation are all proposed as biosorption mechanisms. As a result, C. tamariscifolia was evaluated to be a sustainable biosorbent for dye biosorption from aqueous solutions.

Published: April 2022

The advancement of using the cryogenic energy storage (CES) system has enabled efficient utilization of abandoned wind and solar energy, and the system can be dispatched in the peak hours of regional power load demand to release energy. It can fill the demand gap, which is conducive to the peak regulation of the power system and can further promote the rapid development of new energy. This study optimizes the various types of energy complementary to the CES system using hybrid gravitational search algorithm-local search optimization (hGSA-LS). First, the mathematical model of the energy storage system (ESS) including the CES system is briefly described. Second, an economic scheduling optimization model of the IES is constructed by minimizing the operating cost of the system. Third, the hGSA-LS methods to solve the optimization problem are proposed. Simulations show that the hGSA-LS methodology is more efficient. The simulation results verify the feasibility of CES compared with traditional systems in terms of economic benefits, new energy consumption rate, primary energy saving rate, and carbon emissions under different fluctuations in energy prices. Optimization of the system operation using the proposed hGSA-LS algorithm takes 5.87 s; however, the GA, PSO, and GSA require 12.56, 10.33, and 7.95 s, respectively. Thus, the hGSA-LS algorithm shows a comparatively better performance than GA, PSO, and GSA in terms of time.

Authors: Liu Haobang , Shi Xianming
Published: April 2022

Owning to the fact that ammunition can cause varying degrees of damage to its target, this article presents a damage effectiveness calculation method of hitting targets with ammunition based on Bayesian multinomial distribution to solve the problems of complex processes, few trial times and difficult calculations of damage probability in target-hitting tests with high-tech ammunition, according to a calculation index of damage effectiveness about the occurrence probability of different damage. Based on the concept of symmetry, the idea of “divide damage level—determine distribution—integrate information—solve distribution” is adopted. Firstly, this paper describes the damage effectiveness test of ammunition attacking targets with multiple distributions; secondly, this paper integrates the damage effectiveness information of ammunition strike targets with Dempster–Shafer evidence theory (D–S evidence theory) and symmetry advantage; finally, this paper attempts to solve the symmetric posterior distribution of damage effectiveness parameters with Bayesian theory and the Markov chain Monte Carlo (MCMC) method. The result demonstrates that this method is very significant in improving the calculation accuracy of ammunition damage effectiveness, which could describe the damage effectiveness of ammunition in detail by integrating the prior information with multiple types of damage effectiveness.

Industrialization has resulted in a massive increase in garbage output, which is frequently discharged or stored in waterways like rivers and seas. Due to their toxicity, durability, bioaccumulation, and biomagnification, heavy metals (such as mercury, cadmium, and lead) have been identified as strong biological poisons. Their presence in the aquatic environment has the potential to affect water quality parameters and aquatic life in general. Teleosts’ histopathology provides a sensitive indicator of pollutant-induced stress, because their organs have a central role in the transformation of different active chemical compounds in the aquatic environment. In particular, the gills, kidneys, and liver are placed at the center of toxicological studies. The purpose of this study is to examine the morphological changes caused by heavy metals in the kidney and gills of Boops boops, with a focus on melanomacrophages centers (MMCs) and rodlet cells (RCs) as environmental biomarkers, using histological and histochemical stainings (hematoxylin/eosin, Van Gieson trichrome, Periodic Acid Schiff reaction, and Alcian Blue/PAS 2.5), and immunoperoxidase methods. Our findings show an increase of MMCs and RCs linked to higher exposure to heavy metals, confirming the role of these aggregates and cells as reliable biomarkers of potential aquatic environmental changes reflected in fish fauna. The cytological study of RCs and MMCs could be important in gaining a better understanding of the complicated immune systems of teleosts.

Since December 2019, the COVID-19 pandemic, which originated in Wuhan, China, has resulted in over six million deaths worldwide. Millions of people who survived this SARS-CoV-2 infection show a number of post-COVID complications. Although, the comorbid conditions and post-COVID complexities are to some extent well reviewed and known, the impact of COVID-19 on pre-existing congenital anomalies and genetic diseases are only documented in isolated case reports and case series, so far. In the present review, we analyzed the PubMed indexed literature published between December 2019 and January 2022 to understand this relationship from various points of view, such as susceptibility, severity and heritability. Based on our knowledge, this is the first comprehensive review on COVID-19 and its associations with various congenital anomalies and genetic diseases. According to reported studies, some congenital disorders present high-risk for developing severe COVID-19 since these disorders already include some comorbidities related to the structure and function of the respiratory and cardiovascular systems, leading to severe pneumonia. Other congenital disorders rather cause psychological burdens to patients and are not considered high-risk for the development of severe COVID-19 infection.

Published: April 2022

RNA viruses like SARS-CoV-2, influenza virus, and respiratory syncytial virus (RSV) are dependent on host genes for replication. We investigated if probenecid, an FDA-approved and safe urate-lowering drug that inhibits organic anion transporters (OATs) has prophylactic or therapeutic efficacy to inhibit RSV replication in three epithelial cell lines used in RSV studies, i.e., Vero E6 cells, HEp-2 cells, and in primary normal human bronchoepithelial (NHBE) cells, and in BALB/c mice. The studies showed that nanomolar concentrations of all probenecid regimens prevent RSV strain A and B replication in vitro and RSV strain A in vivo, representing a potential prophylactic and chemotherapeutic for RSV.

Esta pesquisa objetivou conhecer a epidemiologia dos hábitos sexuais e de anticoncepção de jovens de uma universidade do Distrito Federal. Trata-se de um estudo epidemiológico de caráter descritivo, com abordagem quantitativa, sendo um levantamento, entre os anos de 2020 e 2021, com análise de questionários estruturados auto aplicáveis sobre os efeitos do uso de métodos contraceptivos na sexualidade. As variáveis investigadas foram: idade, sexo, escolaridade, uso e conhecimento sobre os contraceptivos, hábitos sexuais, opiniões sobre sexualidade. Os sujeitos da pesquisa foram 252 alunos do Centro Universitário de Brasília (UniCEUB) que assinaram o termo de consentimento livre e esclarecido que já tiveram a sexarca. A pesquisa foi aprovada pelo Comitê de Ética sob nº 4.373.886.  Em relação à primeira relação sexual, 56% dos entrevistados revelaram ter sido após os 18 anos e 20% não fez uso de métodos contraceptivos, já dos que tiveram a relação antes dos 18 anos (44%), 28,5% não fizeram uso de tais métodos nesta relação. Dos entrevistados, 69% referiu usar sempre, 21,8% na maioria das vezes, 2% raramente e 7,2% não faz. Assim, 43,3% usam preservativos, 21,8% contraceptivos orais e 19% dupla proteção. Dos que usam preservativos de barreira, apenas 19% fazem uso durante toda a relação sexual. 49,2% dos estudantes acreditam que o uso de métodos de barreira atrapalha no prazer sexual e 26,6% referem que o uso destes prejudicam a naturalidade e espontaneidade do ato. Tratando-se de parceiros fixos, 58,3% não faz uso de métodos que previnem Infecções Sexualmente Transmissíveis, desses, apenas 29,2% interrompem após realização de exames. A maior parte dos entrevistados (79,4%) recebeu orientações sobre saúde sexual e planejamento familiar, sendo que 6,7% obtiveram estas informações apenas após a 1ª relação. Ademais, a maior parte obteve tais orientações pelas escolas (70,2%), 52,9% dos pais e apenas 22,2% de serviços de saúde. A maior parte dos estudantes (96%) concorda que a responsabilidade pelo uso de contraceptivos deve ser das duas pessoas. Dentre os entrevistados, 76,2% tem um plano de vida, desses 2% não fez uso de contraceptivos na primeira relação e, dos que não tem tal plano, 11% não fizeram uso de anticoncepção. Os resultados demonstram que uma proporção alta dos estudantes teve a primeira relação sexual com menos de 18 anos, além da baixa prevalência do uso correto de métodos anticoncepcionais e proteção contra ISTs. Assim, os achados enfatizam a necessidade da orientação sobre saúde sexual e planejamento familiar com objetivo primário prevenir a gravidez indesejada e doenças sexualmente transmissíveis. Deve-se incentivar essa abordagem em instituições de ensino e serviços de saúde, de forma a proteger a saúde e incentivar o planejamento de vida dos estudantes.

Houve associação significativa entre o uso de insulina (p< 0,01) e a procedência de internação da Unidade de Pronto Atendimento (p < 0,04), com o risco de desenvolver lesão. A prevalência encontrada foi considerada elevada, evidenciando a necessidade da criação de protocolos e treinamento dos profissionais para a prevenção de lesões por pressão no serviço avaliado.

This work consists in the development of a system for data acquisition of parameters in an agricultural application. For this, the system includes the monitoring of soil moisture and atmospheric sensors (temperature and relative humidity), in order to provide subsidies to farmers in decision-making, aiming at a future implementation of an automated irrigation system, with minimization of waste of water resources. Data acquisition is carried out by means of sensors connected to a microcontrolled system, and the signals are transmitted through a radio frequency module using LoRaWanTM protocol. Data is received at a gateway and made available in the cloud, applying Internet of Things (IoT) concepts, and can be monitored in real time in an academic interface. Additionally, the data can also be monitored through a simplified interface accessible through an app developed specifically for the application.

Os percevejos estão entre as pragas de maior importância na cultura da soja, causando danos desde área de produção de sementes quanto de grãos. Atualmente a principal estratégia de controle, é a pulverização de inseticidas químicas. Mas, muitas vezes usado de maneira exagerada e sem critério, e, com isso pode levar a falhas de controle. O objetivo desse trabalho foi avaliar se manejos de inseticida influenciaram no controle de percevejos. O estudo foi realizado em campo experimental da Faculdade de Agronomia e Medicina Veterinária da Universidade de Passo Fundo, safra 2020/21, em delineamento de blocos casualizados, com seis tratamentos considerando os manejos de inseticidas com variação do número e intervalo de aplicações, com quatro repetições. A cultivar utilizada foi BMX Zeus e as avaliações consistiram no monitoramento semanal de insetos, por meio do uso de pano de batida, além de avaliação de danos de tripes. Após a colheita foram realizadas avaliações dos componentes de rendimento e estimativa de rendimento. Os dados obtidos foram submetidos à análise de variância e as médias comparadas através do teste Tukey (P≤ 0,05). Pode-se concluir que, o manejo de inseticidas não influencia o rendimento de grãos, o peso de mil sementes e a densidade populacional de percevejos e tripes, em anos de baixa ocorrência de pragas e em condições de déficit hídrico.

As atividades desenvolvidas pelos centros que prestam serviços de atividades de suporte à vida e saúde humana e animal são responsaveis por gerarem consideraveis quantidade de residuos, alguns propriedades que podem representar riscos à saúde publica e ao meio ambiente. Esses produtos precisam de processos diferenciados em seu manejo, requisitando ou não por tratamento prévio ao seu destino final. Em 2004 a  Resolução da Diretoria Colegiada (RDC) nº 306 da ANVISA (Agência Nacional de Vigilância Sanitária), que entrou em vigor em dezembro de 2004, determina que todos os estabelecimentos de saúde devem elaborar um plano de gerenciamento de resíduos e para tanto, o conhecimento dos sistemas de produção e a forma de manejo é indispensável para o sucesso desse plano. Neste sentido, objetivou-se com esse trabalho, quantificar e gerenciar os resíduos químicos laboratórias provenientes do hospital veterinário do Centro de Ciências Agrárias da Universidade Federal da Paraíba. Assim, foram identificadas as fontes geradoras, os resíduos gerados, as características desses resíduos e a quantidade mensal gerada. Os dados coletados foram avaliados, plotando gráficos. Concluiu-se que grande quantidade de resíduos são descartados mensalmente pelos laboratórios do hospital veterinário, sobretudo, álcool etílico, xilol e eosina. O laboratório de histologia e histopatologia é responsável pelas maiores quantidades de resíduos descartadas/ou descartaveis. Quanto ao gerenciamento desses resíduos, três ações são indespensáveis, a primeira consiste em sua separação no momento e local da sua geração, de acordo com a característica química, estado físico e riscos envolvidos. A segunda consiste no acondicionamento dos resíduos já segregados em sacos ou recipientes que evitem vazamentos e resistam à ruptura. O terceiro passo é o tratamento, que consiste na aplicação do método, técnica ou processo que modifique as características dos riscos inerentes aos resíduos.

Frente as mudanças das práticas assistenciais em saúde mental advindas com a Reforma Psiquiátrica Brasileira e o atual contexto da pandemia Covid-19 que impõe aos serviços novos rearranjos, é imprescindível refletir e debater as práticas realizadas no Centro de Atenção Psicossocial-CAPS. Assim, este estudo tem como objetivo caracterizar as atividades desenvolvidas pelo CAPS no contexto de pandemia da Covid-19 segundo a literatura científica. Quanto aos procedimentos metodológicos, trata-se de uma revisão integrativa de literatura, na qual foram utilizadas as bases de dados online em Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) do Sistema Online de Busca e Análise de Literatura Médica (Medline) e do Banco de Dados em Enfermagem (BDENF) por meio da consulta à Biblioteca Virtual em Saúde (BVS) Os descritores usados foram: Assistência de Enfermagem, Saúde Mental, CAPS, COVID 19, serviços comunitários de saúde. A amostra final foi constituída de 7 artigos. Observou-se que com os impactos desencadeados pela pandemia da Covid-19, os serviços de saúde tiveram que se reorganizar e se adaptar aos novos manejos da saúde, manter o distanciamento social para evitar a propagação do vírus e dar continuidade aos processos de cuidado. Entre as novas práticas surgiram grupos online de apoio, teleconsultas e o aumento da articulação com os serviços da atenção primária a saúde para continuidade do cuidado. Todavia, nota-se que a literatura ainda é escassa na abordagem do tema e, portanto, sugere-se que outros estudos sejam realizados.

A parada cardiorrespiratória (PCR) pode ser definida como a cessação súbita e inesperada dos batimentos cardíacos associados à ausência de respiração e o sucesso em seu atendimento é determinado pelo reconhecimento precoce da PCR, da rápida solicitação do sistema de emergência e da adequada instituição do suporte básico e avançado de vida. Dessa forma, diante de uma PCR, o tempo é o principal determinante de sucesso, visto que cada minuto perdido reduz a chance de sobrevida do nosso paciente em 10%. BRIÃO, 2009, cita em seu trabalho que profissionais de saúde falham em fornecer suporte básico de vida e desfibrilação no tempo adequado, sendo essa questão pouco tratada na literatura nacional. Diante da importância do tema, são necessários estudos para avaliar o conhecimento teórico de médicos sobre o manejo correto de uma parada cardiorrespiratória para intervenções futuras. O objetivo do presente estudo foi avaliar o conhecimento de médicos docentes de uma Universidade sobre o diagnóstico e conduta da parada cardiorrespiratória, além de analisar seu perfil epidemiológico, conhecimento sobre ritmos chocáveis e não chocáveis, uso de fármacos e cuidados pós parada. Trata-se de em estudo transversal, descritivo, quantitativo e qualitativo, realizado no período de junho de 2020 a maio de 2021, no Centro Universitário Unichristus – Fortaleza, CE. Foram respondidos 49 questionários por médicos docentes na modalidade presencial e Google Forms. Dos médicos avaliados, 17 eram do sexo feminino (34,7%) e 32 do sexo masculino (65,3%), com idade variando entre 30 a 68 anos, a maioria com tempo de formação maior que 10 anos (75,5%). Das especialidades presentes, clínica médica (46,7%) e pediatria (16,2%) foram responsáveis por 62,9% do total, sendo as mais frequentes. No que tange a cursos de suporte, ACLS foi o mais praticado (81,8%). Diante da conduta ao encontrar uma pessoa inconsciente no chão, 53,1% responderam avaliar a segurança da cena, seguida de ligar para o serviço de emergência com 36,7%.A desfibrilação como conduta diante de uma fibrilação ventricular foi corretamente identificada por 75,5% dos profissionais. Acerca da técnica empregada nas compressões torácicas, 32,7% dos entrevistados responderam 5 cm e 53,1% responderam 3-5cm. Checagem do pulso após desfibrilação foi indicada em 18,4% das respostas. A partir do presente estudo, pode-se observar a necessidade do aprimoramento e atualização dos profissionais quanto a conduta frente a uma parada cardiorrespiratória (PCR), visto que uma atuação correta e eficaz é responsável por mudar prognóstico e morbimortalidade dos pacientes.
