Paralytic shellfish toxins (PSTs) produced by Alexandrium catenella (formerly A. tamarense) in Korean coastal waters caused the deaths of four people (in 1986 and 1996) who consumed contaminated mussels (Mytilus edulis). This led to more detailed consideration of the risks of PST outbreaks and incidents in Korea, including the introduction of shellfish collection bans. In this study, we investigated the relationships between A. catenella population dynamics and PST accumulation in the mussel M. galloprovincialis. Discharges from the Nakdong River affect the environmental conditions along the Geoje coast, resulting in low salinity and high nutrient levels that trigger blooms of A. catenella. At the toxin peak on 24 April 2017, the toxins detected in A. catenella cells were C1, gonyautoxin (GTX)1 and GTX2, whereas the concentrations of PSTs in M. galloprovincialis were high and in the order of GTX4 > GTX1 > GTX3 > saxitoxin (STX) > GTX2 > neoSTX > decarbamoylgonyautoxin (dcGTX)2 > dc GTX3. The PST level in mussels was also high. At 15 °C, the PSTs are constantly found to be higher (10-fold higher in 2017 and 30-fold higher in 2018) than safe levels for human consumption (80 μg STX diHCl equivalents 100 g−1).

Dengue is placing huge burdens on the Malaysian healthcare system as well as the economy. With the expansion in the number of high-rise residential buildings, particularly in the urban centers, the flight range and behavior of Aedes mosquitoes may be altered in this habitat type. In this study, we aimed to expand the understanding of the vertical distribution and dispersal of Aedes in nine selected high-rise residences in Kuala Lumpur, Selangor, and Johor using ovitraps as the sampling method. We discovered that Ae. aegypti is the predominant species in all study sites. Both Ae. aegypti and Ae. albopictus are most abundant within the first three levels and could be found up to level 21 (approximately 61.1–63.0 m). Pearson correlation analyses exhibited negative correlations in eight out of nine study sites between the ovitrap indexes (OIs) within each floor level, suggesting that Aedes density decreased as the building level increased. Our findings provide information to the public health authorities on ‘hot spot’ floors for effective suppression of dengue transmission.
Hsv-1 Endocytic Entry into a Human Oligodendrocytic Cell Line Is Mediated by Clathrin and Dynamin but Not Caveolin
Authors: Praena Beatriz , Bello-Morales Raquel , López-Guerrero José Antonio
Published: July 2020

Endocytosis is a pathway used by viruses to enter cells that can be classified based on the proteins involved, such as dynamin, clathrin or caveolin. Although the entry of herpes simplex type 1 (HSV-1) by endocytosis has been documented in different cell types, its dependence on clathrin has not been described whereas its dependence on dynamin has been shown according to the cell line used. The present work shows how clathrin-mediated endocytosis (CME) is one way that HSV-1 infects the human oligodendroglial (HOG) cell line. Partial dynamin inhibition using dynasore revealed a relationship between decrease of infection and dynamin inhibition, measured by viral titration and immunoblot. Co-localization between dynamin and HSV-1 was verified by immunofluorescence at the moment of viral entry into the cell. Inhibition by chlorpromazine revealed that viral progeny also decreased when clathrin was partially inhibited in our cell line. RT-qPCR of immediately early viral genes, specific entry assays and electron microscopy all confirmed clathrin’s participation in HSV-1 entry into HOG cells. In contrast, caveolin entry assays showed no effect on the entry of this virus. Therefore, our results suggest the participation of dynamin and clathrin during endocytosis of HSV-1 in HOG cells.

Published: July 2020

Due to simplicity and low costs, waste stabilisation ponds (WSPs) have become one of the most popular biological wastewater treatment systems that are applied in many places around the globe. Increasingly, pond modelling has become an interesting tool to improve and optimise their performance. Unlike process-driven models, generalised linear models (GLMs) can deliver considerable practical values in specific case studies with limited resources of time, data and mechanistic understanding, especially in the case of pond systems containing vast complexity of many unknown processes. This study aimed to investigate the key driving factors of dissolved oxygen variability in Ucubamba WSP (Ecuador), by applying and comparing numerous GLMs. Particularly, using different data partitioning and cross-validation strategies, we compared the predictive accuracy of 83 GLMs. The obtained results showed that chlorophyll a had a strong impact on the dissolved oxygen (DO) level near the water surface, while organic matter could be the most influential factor on the DO variability at the bottom of the pond. Among the 83 models, the optimal models were pond- and depth-specific. Specifically, among the ponds, the models of MPs predicted DO more precisely than those of facultative ponds; while within a pond, the models of the surface performed better than those of the bottom. Using mean absolute error (MAE) and symmetric mean absolute percentage error (SMAPE) to represent model predictive performance, it was found that MAEs varied in the range of 0.22–2.75 mg L−1 in the training period and 0.74–3.54 mg L−1 in the validation period; while SMAPEs were in the range of 2.35–38.70% in the training period and 10.88–71.62% in the validation period. By providing insights into the oxygen-related processes, the findings could be valuable for future pond operation and monitoring.

Published: July 2020

Adsorption has been regarded as one of the most efficient and economic methods for the removal of antibiotics from aqueous solutions. In this work, different graphene-based magnetic nanocomposites using a modified solvothermal method were synthesized and employed to remove sulfadiazine (SDZ) from water. The adsorption capacity of the optimal magnetic reduced graphene oxide (MrGO) was approximately 3.24 times that of pure Fe3O4. After five repeated adsorption cycles, the removal rate of SDZ (100 μg/L) by MrGO nanocomposites was still around 89.3%, which was only about a 3% decrease compared to that in the first cycle. Mechanism investigations showed that both chemical and physical adsorption contributed to the removal of SDZ. The excellent adsorption performance and recyclability of MrGO nanocomposites could be attributed to their wonderful 3D interconnected petal-like structures. The MrGO with SDZ could be easily recollected by magnetic separation. The MrGO also exhibited excellent adsorption performance in the purification of real polluted water.

Pretendeu-se, com este trabalho, verificar como se dá a abordagem da literatura em provas e exames vestibulares. Especificamente, investigamos como foi tratada a literatura na prova do Exame Nacional do Ensino Médio (ENEM) – edição 2012, estabelecendo correlações com a prova de literatura do vestibular 2012-2013 da UFPE. Analisamos os dois instrumentos à luz de pressupostos teóricos sustentados por autores como Cosson (2009), Bordini e Aguiar (1983), Paulino (2005) e Soares (2004). Tentando verificar se as provas estavam em consonância com o princípio teórico-metodológico de formar leitores proficientes de textos literários, realizamos uma pesquisa documental, descritiva e interpretativa. Concluímos que a prova do ENEM representa um avanço no tratamento do texto literário, se comparada a exames tradicionais, como o da UFPE. Porém, ainda há o que melhorar na forma como a aprendizagem da literatura é avaliada tanto numa prova quanto noutra, se quisermos, de fato, formar leitores proficientes de textos literários.

Published: July 2020

Background and aims: Hemodialysis (HD) is considered as the main method of renal replacement therapy (RRT) for end-stage renal disease (ESRD) patients in many countries including Iran. Given the limited number of epidemiological studies in this regard at the provincial level across the country, the present study aimed to describe the demographic and clinical characteristics of ESRD patients and determine the most important causes of ESRD in Hamadan Province. Methods: This cross-sectional study was conducted on 508 HD patients in Hamadan province in January 2017. The checklist used to gather information comprised of the patient’s demographic and clinical information. The analysis was carried out using descriptive analysis including frequency tables and charts and the chi-square statistic test was used to compare the groups using Stata software, version 12. Results: The prevalence rate of HD treatment was 288.9 per million population (PMP). Further, most under HD patients were married, illiterate, and urban residents. The mean age of patients at the diagnosis was 47.64 ± 15.17 years. Hypertension (37.4%), diabetes (28.74%), and glomerulonephritis (10.63%) were the common causes of ESRD. Eventually, there was a significant difference between ESRD causes according to gender and residency (P<0.05). Conclusion: In general, the prevalence rate of HD in Hamadan was relatively similar to that of developing countries although it was lower than the national average. Furthermore, hypertension and diabetes were the common causes of ESRD in Hamadan Province. Therefore, preventive strategies should be taken to modify their risk factors.

Published: July 2020

This paper proposes an algorithm that enhances the speed of transmission and secure images that are transmitted over internet or a network. The proposed cryptosystem uses a modified k-shuffling technique to scramble pixels of images and further decomposes them using Residue Number System. Simulations are done using two moduli sets with the modified k-shuffle technique. Analyses of results showed that both simulations could secure images without any loss of information and also the time taken for a complete encryption/decryption process is dependent on the moduli set. Among the chosen moduli sets, the even moduli set optimizes and completes execution using less time as compared to the traditional moduli set. The proposed scheme also showed resistance to statistical attacks (histogram, ciphertext, correlation attacks) and a significant reduction in the size of cipher images which enhances the speed of transmission over network.

Introduction: An increase in epizootic activity has been registered in a number of plague foci in the Russian Federation over the past few years. As part of securing sanitary and epidemiologic wellbeing of the population living in the natural foci of the disease, a mass immunization with a live plague vaccine based of the Yersinia pestis EV line NIIEG vaccine strain was carried out. Objectives: The purpose of the study was to assess the influence of a complex of factors including age, gender, health status, the number of previous vaccinations against plague, blood groups, and HLA gene polymorphism on the state of the cellular and humoral immune response in people vaccinated with the live plague vaccine. Materials and methods: The analysis of venous blood of 347 volunteers included determination of the concentration of specific antibodies to the capsular antigen (F1) of plague microbe, spontaneous and induced production of marker cytokines (IFN-γ, TNF-α, and IL-4) by ELISA, and genes of the main histocompatibility complex (HLA) class II by real-time PCR. We also analyzed medical documentation (Form 025/u) and the results of a questionnaire-based survey of the vaccinated people. Results and discussion: We established the influence of various factors, including genetic ones, on marker indicators of the humoral and cellular immune response in persons vaccinated with the live plague vaccine. We also characterized the relationship between the level of specific antibodies to plague microbe F1 production and some cytokines and the age and the number of previous vaccinations in our volunteers. The most common gene variants of the main histocompatibility complex of class II (HLA-DQA1, HLA-DQB1 and HLA-DRB1) in the cohort were identified and possible relationships between the production of IFN-γ, TNF-α, IL-4 and allelic polymorphism of HLA class II genes were determined. Conclusions: Immunologic reactivity in people vaccinated with the live plague vaccine is mainly determined by age, the number of previous vaccinations against this infection, and individual characteristics of HLA gene polymorphism.
Comparative Analysis of Triticum aestivum L. (Poaceae, Poales) and Pisum sativum L. (Fabaceae, Fabales) Resistance to Heavy Metals
Authors: Erofeeva E. A.
Published: July 2020

Heavy metals are most common soil pollutants, including agricultural land. At the same time, the level of heavy metal pollution can significantly exceed the standards. Pea (Pisum sativum L.) and wheat (Triticum aestivum L.) are most important crops. At the same time, no comparative analysis of their resistance to high concentrations of heavy metals has been carried out. In connection with this, the resistance of T. aestivum and P. sativum seedlings to the chronic effects of lead and copper salts in the range of lethal concentrations for T. aestivum was comparatively evaluated (0.15, 0.30 and 0.60 g/L of copper sulfate; 0.5, 1.0 and 1.5 g/L of lead nitrate) in experimental conditions. All studied concentrations of the toxicants caused a decrease in seed germination of T. aestivum relative to the control by 19–38% and 23–58% when exposed to lead nitrate and copper sulphate, respectively, which indicated the manifestation of lethal effects. All studied concentrations of both toxicants caused a significant reduction in the root system length (from 69% to 25 times) and shoot height (by 25–76%) as compared with the control level in T. aestuvum seedlings, and also led to an increase in the intensity of lipid peroxidation in seedling shoots, indicating the development of a stress reaction. At the same time, the studied concentrations of heavy metal salts, which were lethal for T. aestivum, did not cause almost any disturbances of the studied parameters in P. sativum, except for a decrease in the root system length after lead nitrate exposure. Thus, seed germination, growth processes of the root system and shoot, as well as peroxide homeostasis in P. sativum seedlings were much more resistant to the studied concentrations of lead nitrate and copper sulfate as compared with these parameters of T. aestivum.
Influence of Agroclimatic Conditions, Life Form and Host Species on the Species Complex of Wheat Septoria Pathogens
Authors: Zeleneva Ju. V. , Afanasenko O. S. , Soodnikova V. P.
Published: July 2020

Currently, septoria is the basis of the pathogenic complex on wheat crops in Russia, occupying the predominant position among harmful fungal diseases. In case of severe wheat damage, the crop loss caused by the fungus Z. tritici, makes up from 10–25 to 40–60%. The crop loss caused by the fungus P. nodorum parasitizing is from 10–20 to 30–50% during the years of epiphytoty. The question of the economic significance of P. avenae has not yet been examined completely. However, depending on the area of wheat cultivation and the year of observation, its part in the septorian population may reach up to 76.9%. It was of interest to study in detail the influence of conditions of the specific year, life form, and species of wheat on the formation of the species composition of Septoria in the pathogenic complex of wheat. Among the complex set of factors included in the concept of the environment, a significant role belongs to its abiotic components, namely, climate and weather, but the variety as an environment-forming factor has a decisive role. Our studies were carried out during 2010–2017. During the research period, the weather conditions varied significantly over the years and were not always favorable for the development of plants and formation of a good wheat crop. During the study, deviations in the amount of precipitations during the vegetation period, and, in general, over the year from the long-term average annual values, were noted. The years of 2012, 2014 and 2015 were characterized by the highest moisture supply during the vegetation season. It has been predicted that cooler days of April and May will promote the better development of P. avenae and P. nodorum. P. nodorum receives its predominant development during the years with wetter weather within the vegetation period of wheat, in contrast to Z. tritici more resistant to low humidity. These data demonstrate adaptation of the pathogen to conditions of an increased temperature regime and reduced rainfall amount.

Authors: Kiseleva N. V.
Published: July 2020

In the birch-pine forests of the Ilmeny Reserve the bank vole is predominated by numbers, the pygmy wood mice being in the second place. The results of our monitoring of the numbers of these rodents for 27 years (1991–2018) are presented. 1,610 rodents were caught,of which the bank vole accounted for 52.6%, the pygmy wood mouse for 32%, and other species for 15.4%. The autumn abundance of the bank vole was 4.6±1.8 and 18.9±2.6 ind./100 trap-days for 1991–1999 and 2000 – 2018, respectively; that of the pygmy wood mouse was 2.1±1.9 and 18.9±2.6 ind./100 trap-days, respectively. Since 2000, the peak amplitude of the bank vole number has increased by 1.1– 2.5 times, that of the pygmy wood mouse has increased by 2.5–4.2 times. Since 2006, the number peaks of these rodents began to repeat after 2–3 years. Over eighteen years (2000–2018), the autumn abundance of the bank vole twice (2008 and 2017) reached its peak values, at which the reproduction of voles ceased in July or early August. The correlation coefficient of the autumn abundance of the bank vole and pygmy wood mouse for 1996–2018 was 0.64±0.1. The spring abundance of the pygmy wood mouse has begun to more often exceed the spring abundance of the bank vole. Changes in the population cycles of the bank vole and pygmy wood mouse were obviously associated with some climatic features of the recent decades.

Published: July 2020

Currently, Electroencephalogram (EEG) is extensively used for diagnosing the epilepsy. The objective of this research is to investigate the changes in epilepsy frequency by proposing a new optimization based deep learning model. At first, the EEG recordings were acquired from two online databases; Bern Barcelona (BB), and Bonn University (BU). Then, Chebyshev type two filter was implemented to remove the unwanted artifacts from the acquired EEG signals. Further, Multivariate Variational Mode Decomposition (MVMD) methodology was applied to decompose the denoised EEG signals. The signal decomposition helps in finding the necessary information, which required to model the complex time series data. Then, the features were extracted from decomposed signals by using fifteen entropy, linear and statistical features. In addition, enhanced firefly optimization technique was proposed for optimizing the extracted features. In the enhanced firefly optimizer, a crossover operator of genetic algorithm was added for enhancing the local convergence rate that gives better classification. At last, the optimized feature vectors were classified by Deep Neural Network (DNN) that includes two circumstances (seizure and healthy), and (Interictal, ictal, and normal). From the experimental simulation, the proposed model improvement maximum of 1.4%, and 8.82% of accuracy in BU and BB EEG datasets, respectively related to the existing models.

The main motive of the miniaturized sensing antennas is low profile, compact square antennas to operate in K and Ka band applications. Since Substrate integrated waveguide (SIW) technology exhibits low copper loss, reduced surface waves and low dielectric loss property it is involved in the design. In this paper, a square waveguide resonator is proposed to covers frequency range of 20 to 45 GHz and the electrical parameters of the antenna like return loss, gain, radiation pattern, and VSWR are investigated. The square resonator has conducting cylinders know as via-holes along the sides of the patch which makes it a good electrical conductor (EC) and from other side a good magnetic conductor (MC). The proposed square resonators contribute to the design of compact structure. The structure of HMSIW has Triple band which has maximum return loss of -20.5 dB at 36.75 GHz whereas FMSIW square shaped antenna has Hepta band maximum return loss of -21.5 dB at 40.5 GHz..

A europeização no ensino da língua portuguesa presente no conto "Menina Vitória", de Arnaldo Santos", e "Infância", de Graciliano Ramos
Authors: Santos Robson Caetano dos
Published: July 2020

Neste artigo será analisado como nos textos literários de língua portuguesa Menina Vitória, de Arnaldo Santos, e Infância, de Graciliano Ramos, é realizado de forma sutil, a denúncia ideológica sobre a forma como a língua portuguesa pode ser ensinada nas escolas de ex-colônias de Portugal. Em ambos textos, tanto no personagem Gigi, quanto no próprio Graciliano, em seu relato autobiográfico, o ensino da língua, tal como é imposto com o viés de superioridade europeia e de pureza da língua, é traumático, doloroso e incondizente com o espaço cultural em que estes personagens habitam. Todavia esperou-se comprovar que a própria forma literária ou estética em que se apresenta a forma de narrar esses textos demonstram que esse autoritário e despótico ensino da língua não sairá vitorioso: em Menina Vitória, aparecem termos em quimbundo e outros da cultura angolana imiscuídos na língua portuguesa; em Infância, a linguagem rebuscada, como um cipoal, encontrada pelo menino-leitor Graciliano, no livro didático do barão de Macaúbas, será totalmente o oposto da futura linguagem do escritor adulto em seu fazer literário: enxuta, seca, econômica e direta. Como amparo teórico foi utilizado Frantz Fanon, Benjamin Abdala Junior e Jacques Rancière.
A ciclicalidade da política fiscal Brasileira revisitada
Authors: De Jesus Cleiton Silva
Published: July 2020

Estudos empíricos realizados nas últimas duas décadas têm sugerido que a condução da política fiscal nos países em desenvolvimento é procíclica. Além disso, a dinâmica da dívida pública e os choques inflacionários podem ajudar a explicar comportamento da autoridade fiscal numa economia em desenvolvimento. O objetivo deste artigo é verificar a ciclicalidade da política fiscal brasileira a partir da estimação de uma função de reação fiscal que, além de levar em conta uma medida do ciclo econômico, também considera a dívida pública e a taxa de inflação. Os principais resultados desta pesquisa sugerem que: i) a política fiscal no período foi contracíclica, mas só se tornou contracíclica recentemente; ii) os estabilizadores fiscais automáticos do lado da despesa têm se tornado mais efetivos; iii) o comportamento das finanças públicas, na média, tem sido coerente com a estabilização da dívida pública e iv) não é claro se a autoridade fiscal tem contemplado a inflação em seus objetivos.

Published: July 2020

The objective of the this study is to present the perception of Physical Education teachers in Porto Alegre and the Metropolitan Region, in Rio Grande do Sul, about the inclusion of students with Autism Spectrum Disorder (ASD) in regular school. In this context, semi-structured interviews have been conducted with eight Physical Education teachers who have students with ASD. The interpretation of the information occurred through thematic content analysis. From the reports of the teachers, aspects of the participation of students with ASD in school Physical Education classes have been identified: willingness to follow routines, including activities, materials and people; better engagement in exploratory and object manipulation activities in early child education; greater participation in activities with previously defined steps in Elementary School. Teaching strategies include paying attention to the particularities of children with ASD, outlining objectives and methods related to individual needs and potential. Activities and objects, specific to the routine of each student, have been mentioned as a way of establishing initial engagement in classes, followed by the use of different strategies, in order to promote inclusion in classes on an equal basis with peers without disabilities. The peers’ mediation was mentioned, bringing benefits to the class of students. In addition, interdisciplinary work was mentioned as indispensable to an effective Inclusive Education. It is concluded that the characteristics presented by students with ASD in Physical Education classes, lead teachers to seek for strategies that allow them to favor their teaching and learning of those students, with social skills being widely evidenced in this process.

The aim of study was to investigate the opinion of Physical Education teachers on academic training for teaching work with students with disabilities. The sample consisted of 21 Physical Education teachers from the public and private teaching network of Boa Vista/RR, of both genres and with average age of 37.6 years. For data collection was used questionnaire adapted from Mendes (2013), composed of 09 objective questions. The results were analyzed using descriptive statistics. We found that: a) disciplines aimed at inclusion in academic education, most teachers (33%) had only one discipline, followed by others (24%) who attended two disciplines. b) regarding the participation of courses in Adapted Physical Education, most of the teachers (76%) participated in courses; c) in relation to preparation to teach inclusive classes in Physical Education classes, (57%) report feeling prepared, followed by (38%) who do not feel prepared. Thus, we conclude that, for teachers participating in the research, it is essential the inclusion of disciplines who aimed work with people with disabilities in higher education, as it may help future teachers to overcome challenges of the classroom and contribute their teaching methods. Also, academic formation and participation in specific courses in Adapted Physical Education can be differential for the performance of Physical Education teachers with students with disabilities at school.

Published: July 2020

Technologies are conditions for positive changes in the environment of industry, services, commerce and others. The implementation of new technologies requires adaptations for the insertion of mechanisms capable of increasing the efficiency of the sector, improving the quality of the product, improving the training of professionals, as well as structuring effective improvements in the system. In the universe of options for framing changes, an impact study for the insertion of technological bases must be made, otherwise, it may bring loss in planned investment in a certain application view. This work addresses the implementation of hygiene and the regulatory standard in the spiral mixer, estimating to validate the safety and quality parameters for the proper installation of the kneader, which because of the adequacy of the minimum standards of hygiene and safety. The methodology applied in the study, which is configured as a case study, whose guiding aspect is the observation and description of the rules for the allocation of adequate conditions for the device to work within the necessary standards. The expectation of the studies carried out in this work is to clarify the rules and the adaptation of the points to bring together the inclusion of technology within the limitations in the application environment. The study is carried out in a commercial environment in the City of Manaus.

Issues relating to the efficient application of passive solar protection in multi-family residential buildings
Authors: Kobylarczyk Justyna , Marchwiński Janusz , Zielonko-Jung Katarzyna
Published: July 2020

The following article is intended to discuss the issues concerning the introduction
of passive measures aimed at improving solar protection in multi-family buildings.
A system of classifying these methods into two groups of solutions (architectural
and material-building) was applied. The first group includes issues concerning
facade design, the spatial features of which (such as loggias, balconies and other
overhangs) can be treated as one of the solar protection methods. The authors’
own studies are presented and expressed in a sequence of formulas. The formulas
enable assessment of the effectiveness of the above elements, depending on
external conditions. As far as the second group is concerned, material-construction
solutions for building facades and roofs are discussed. The solutions mentioned
include solar-control glazing, spatial shading elements (such as venetian blinds,
roller blinds), roof and façade vegetation, and the thermal mass of the building.
The essence of the functioning of the analysed solutions in relation to the
characteristic functional specificity of multi-family buildings is discussed.
Problematic areas of application of the above methods are indicated. As shown in
the study, problematic areas may include a group of utilitarian-operating, economic
and aesthetic issues, in the case of which the use of passive solutions encounters
limitations. In conclusion, the possibilities for alleviating these limitations are
highlighted. The authors’ own solutions presented in the following paper can
contribute to energy savings and may thus prove beneficial for environmental
reasons, thereby serving the aims of sustainable development.
