Well-posedness, wave breaking, Holder continuity and periodic peakons for a nonlocal sine-µ-Camassa-Holm equation
Authors: Qin Guoquan , Yan Zhenya , Guo Boling
Published: December 2021

In this paper, we investigate the initial value problem of a nonlocal
sine-type µ-Camassa-Holm (µCH) equation, which is the µ-version of the
sine-type CH equation. We first discuss its local well-posedness in the
framework of Besov spaces. Then a sufficient condition on the initial
data is provided to ensure the occurance of the wave-breaking
phenomenon. We finally prove the H¨older continuity of the
data-to-solution map, and find the explicit formula of the global weak
periodic peakon solution.

Published: December 2021

Respiratory disease in weaned pigs is a common problem in the field,
with a complex aetiology of both viruses and bacteria. In the present
study, we investigated the presence of eleven viruses in nasal swabs
collected from nurseries (fifty-five clinical outbreaks) under the
suspicion of swine influenza A virus (swIAV) by cough and fever.
The other ten viruses included influenza B (IBV) and influenza D viruses
(IDV), Porcine reproductive and respiratory syndrome virus
(PRRSV), Porcine respiratory coronavirus (PRCV), Porcine
cytomegalovirus (PCMV), porcine circoviruses 2 (PCV2), 3 (PCV3)
and 4 (PCV), Porcine parainfluenza 1 virus (PPIV1) and
Swine orthopneumovirus (SOV). Twenty-nine swIAV-positive cases
and twenty-six cases of swIAV-negative respiratory disease were
primarily established. IBV, IBD, PCV4 and PPIV1 were not found in any
case, while PRCV, SOV, and PCMV were more likely to be found in
swIAV-positive nurseries with respiratory disease (
p<0.05) although, globally, PCV3, PRRSV, and PCMV were
the most frequently detected agents on herd level. At an individual
level, the prevalence of different viruses was: swIAV 48.6%; PRCV
48.0%; PRRSV 31.6%; SOV 33.8%; PCMV 48.3%, PCV2 36.0%; and PCV3
33.0%. Beyond that, it was common to find animals with low Ct values
(< 30) for all agents except for PCV2 and PCV3. When analysed
the association between different pathogens, PRCV was the one with the
most associations. It positively interacted ( p < 0.05)
with swIAV and SOV but was negatively associated ( p <
0.05) with PRRSV and PCVM. Besides these, swIAV and PRRSV were
negatively related (p < 0.05). Further analysis of suckling
pigs showed that circulation of PRCV, PCMV, SOV, and PCV3 started in the
maternities, suggesting a role of the sows in the transmission. Overall,
our data may contribute to a better understanding of the complex
aetiology and the epidemiology of respiratory disease in weaners. This
is the first report of SOV in Spain.
A probability-based multiscale model to quantify the impact of hydropeaking on mesohabitat suitability in rivers
Authors: Jelovica Bähar , Marttila Hannu , Ashraf Faisal Bin , Klöve Björn , Haghighi Ali Torabi
Published: December 2021

One of the negative effects of hydropower on river environment includes
rapid changes in flow and habitat conditions. Any sudden flow change
could force fish to move towards a refuge area in a short period of
time, causing serious disturbances in the life cycle of the fish. A
probability-based multiscale model was developed to quantify the impact
of hydropeaking on habitat suitability for two fish species. The model
used habitat preference curves, river flow and depth to develop the
suitability maps. The suitability index maps reveal that habitat
suitability deteriorates as flow increases in this part of the river.
The probability model showed that, on average, suitability indices are
higher for adult grayling than juvenile trout in hydropeaking events in
the studied area. In addition, the life stages of fish determine their
response to the sudden flow change. The method developed shows the
potential to be used in river management and the evaluation of
hydropeaking impacts in river systems affected by hydropower.

Authors: Pires Larissa Do Nascimento , Peduzzi Luiz O. Q.
Published: December 2021

A detecção das estrelas de nêutrons consiste em um dos eventos científicos mais singulares para o campo da Astronomia. Esta descoberta, protagonizada pela astrônoma Jocelyn Bell Burnell, possibilitou a identificação dos primeiros sinais que viriam posteriormente a serem reconhecidos como pulsares, o que permitiu uma melhor compreensão sobre o processo de evolução das estrelas. No ensino de Física e de Astronomia, no entanto, existe um desconhecimento das/os docentes e discentes sobre o processo de evolução estelar. Neste artigo, desenvolvemos uma pesquisa bibliográfica de maneira a investigar como a história da descoberta dos pulsares e a atuação de Jocelyn Bell Burnell neste episódio se manifesta em trabalhos publicados nas últimas décadas no campo do ensino de Física e de Astronomia, bem como em pesquisas acadêmicas destas áreas. Para o estudo, selecionamos 35 trabalhos, dentre artigos publicados em periódicos e eventos, além de dissertações e teses. O desenvolvimento da análise se baseou em fontes primárias e secundárias que versam sobre elementos históricos relativos à descoberta dos pulsares. Concluímos que pontuais trabalhos realizam uma discussão histórica sobre estes objetos celestes, principalmente produções acadêmicas no campo da Física e da Astronomia, enquanto pesquisas no campo do ensino concentram discussões em um âmbito mais conceitual. Indicamos que este episódio apresenta potencialidades para estudos sobre natureza da ciência e sobre a visibilidade das mulheres na ciência.

Authors: Benite Cláudio Roberto Machado , Camargo Marysson Jonas Rodrigues , Benite Anna Maria Canavarro
Published: December 2021

Neste estudo objetivamos analisar os aspectos intersubjetivos das interações linguísticas em ambiente virtual, tendo como suporte a teoria do agir comunicativo em contexto de formação docente em rede com foco na inclusão escolar. Os dados foram coletados a partir do design e desenvolvimento de parte de uma pesquisa-ação realizada em um curso de formação de professores de química para a diversidade, por meio do Moodle, em Goiânia-GO pela Rede Goiana de Pesquisa em Educação Especial/Inclusiva (RPEI).  Nossos resultados nos permitiram categorizar os atos de falas registrados em fóruns online como atos regulativos, constatativos e expressivos que são categorias de análise da teoria da ação comunicativa de Jürgen Habermas. A investigação nos permitiu repensar a formação dos professores de química em termos de razão comunicativa contemplando o diálogo assimétrico como base para a formação da identidade dos futuros professores para atuarem na diversidade da sala de aula, contrapondo-nos as influências da razão técnica caracterizada pela transmissão de informações desprovidas de conhecimentos vivenciais.
TECNOLOGIAS ASSISTIVAS NO ENSINO DE CIÊNCIAS A DISCENTES COM DEFICIÊNCIA VISUAL: A PERSPECTIVA DE SUAS PROFESSORAS
Authors: Silva Tatiane Santos , Landim de Souza Myrna Friederichs
Published: December 2021

O ensino de ciências na escola inclusiva necessita de profundas reflexões, principalmente no tocante à formação docente, bem como aos recursos e condições disponíveis aos profissionais. O presente trabalho teve como objetivo analisar o ensino de Ciências para alunos e alunas com deficiência visual, com e sem a utilização de recursos de tecnologias assistivas, na perspectiva de suas professoras de ciências em uma escola da rede pública de ensino em Aracaju/SE. A pesquisa faz uso de uma abordagem qualitativa, tendo sido usadas, para a coleta dos dados, observações em campo e entrevistas semiestruturadas com duas professoras que ministraram aulas para alunos e alunas com deficiência visual. Na primeira etapa da pesquisa, a professora de ciências entrevistada não tinha nenhum tipo de recurso disponível para o ensino a alunos com deficiência visual. Já na segunda etapa, outra professora recebeu e utilizou em suas aulas recursos de tecnologia assistiva sobre células e tecidos, que foram elaborados e fornecidos pelas autoras da presente pesquisa. As participantes relataram a existência de grandes dificuldades no ensino para seus alunos com deficiência visual, não possuindo qualquer formação, inicial ou continuada, sobre educação inclusiva. Além disso, recursos que proporcionam o acesso a elementos estritamente visuais no ensino de ciências e seriam de extrema importância para a aprendizagem dos alunos, não estariam sendo disponibilizados. Desse modo, faz-se necessário constantemente ouvir os docentes, que vivenciam a realidade escolar e são personagens fundamentais para contribuir para a implantação efetiva dessas políticas e seu aperfeiçoamento.
OS CONHECIMENTOS TECNOLÓGICOS NA PRÁTICA EDUCATIVA: REFLEXÕES RESSURGENTES NA FORMAÇÃO DE DOCENTES DE CIÊNCIAS E BIOLOGIA
Authors: Barbosa Pércia Paiva
Published: December 2021

Há algumas décadas, defende-se a necessidade de se preparar professores de Ciências e Biologia para o adequado uso das “tecnologias” no ensino, sendo que pesquisas nessa área podem ser boas aliadas para propostas mais exitosas de formação docente. Logo, investigou-se 17 graduandos do curso de Ciências Biológicas, desenvolvido pela Universidade de São Paulo, durante as aulas de uma disciplina optativa focada no ensino de Zoologia. Como objetivos, pretendia-se identificar: i) indícios de conhecimentos tecnológicos dos graduandos pesquisados; ii) se (e como) a referida disciplina possibilitou o desenvolvimento desses conhecimentos. Primeiramente, foi aplicado um questionário focado na identificação de conhecimentos tecnológicos (T-CoRe), sendo que os diálogos dos graduandos durante a elaboração de suas respostas a esse instrumento foram gravados, posteriormente transcritos e analisados, segundo Bardin (2013), o que também foi realizado com as respostas escritas desses estudantes. Em seguida, entrevistas foram realizadas com alguns participantes. Identificou-se compreensões relativamente adequadas dos graduandos a respeito do uso pedagógico das “tecnologias”. Entretanto, também foram identificadas lacunas em alguns conhecimentos considerados importantes para o desenvolvimento da Educação Científica de aprendizes nas escolas. Esses resultados são coerentes com a etapa de formação dos graduandos pesquisados, entretanto reforçam a necessidade de os diferentes tipos de conhecimentos (inclusive tecnológicos) serem abordados, de forma contínua e integrada, ao longo da formação do educador.
Complexity of Practical Work in Portuguese Primary Science Textbooks
Authors: Ferreira Sílvia , Saraiva Leonor
Published: December 2021

Practical work and textbooks have an important role in primary science education. This study analyses the complexity of practical work in Portuguese primary science textbooks. The level of complexity was appreciated by the level of conceptual demand of practical work, as given by the type of practical work, the complexity of scientific knowledge, the complexity of cognitive skills and the degree of relation between theory and practice. The explicitness of practical work was also analysed. The study followed an approach that combines quantitative and qualitative methods of analysis and a total of 176 units of analysis were evaluated from six science textbooks, chosen among the most selected in Portuguese primary schools. The results showed that textbooks evidence a tendency towards a low level of conceptual demand of practical work, considering the proposals for practical activities and the related evaluation questions. Practical activities, mainly focused on practical exercises and illustrative experiences, tend to mobilize scientific knowledge and cognitive skills of a low level of complexity and point out to an apparent relation between theory and practice. The evaluation questions present a lower level of conceptual demand. The results also showed a weak concern with the explicitness of the practical work. However, findings also indicated that there are differences between the textbooks.

Consideramos 89 pesquisas, sendo 66 nacionais e 23 internacionais, selecionadas por meio de consulta às bibliotecas virtuais ProQuest Education Resources Information Center e Web of Science, ao Portal de Periódicos CAPES e aos Anais do ENPEC. As pesquisas foram analisadas no software NVivo 12® para quatro categorias: (a) compreensões e propósitos da avaliação da aprendizagem, (b) relações entre a avaliação e as interações discursivas, (c) pressupostos da avaliação da aprendizagem e (d) categorias analíticas. As pesquisas indicam a necessidade de considerar as dinâmicas discursivas na compreensão conceitual da avaliação e em como ela é estruturada segundo padrões interacionais para que os alunos elaborem significados. Os estudos destacam múltiplos propósitos e a necessidade da ampliação de espaços que valorizem a expressão de ideias científicas dos alunos, sobretudo, pelo discurso dialógico. A partir das proposições das pesquisas, enfatizamos a centralidade da avaliação na articulação entre pensamento científico e linguagem por um enfoque linguístico, epistêmico e situado no ensino de ciências.
REDE DE SENTIDOS NA FORMAÇÃO DOCENTE EM FÍSICA: A TEORIA DA ATIVIDADE COMO REFERENCIAL TEÓRICO-METODOLÓGICO
Authors: Umpierre Andréa Borges , Ritter Jaqueline
Published: December 2021

O presente artigo tem como sujeitos os licenciandos em Física a partir do sexto semestre objetivando acompanhar o movimento de apropriação dos Saberes Docentes após terem concluído as disciplinas de Atividades de Ensino de Física oferecidas pelo curso de Licenciatura em Física. A pesquisa, em sentido mais amplo, está pautada no referencial da Teoria da Atividade (TA) desenvolvida por Leontiev (1978), visando a entender o sentido pessoal norteador dos “motivos” que levam ao desenvolvimento de uma “atividade”, a saber, a Atividade docente. Neste ínterim, o objetivo deste trabalho, consistiu em compreender como se dá o desenvolvimento desse estado de consciência dos licenciandos quando mediado pelos conhecimentos e saberes relativos à humana docência, desenvolvidos nas disciplinas de Atividades de Ensino de Física. A pesquisa parte do seguinte interrogante: após cursarem as quatro disciplinas de Atividades de Ensino de Física (400h), como os licenciandos percebem-se em Atividade docente como resultado desses processos formativos? Entendemos que a Teoria da Atividade (TA) possibilitar-nos-á olhar para os processos mediacionais de internalização dos conceitos e apropriação de saberes docentes desenvolvidos ao longo de um curso de licenciatura. Esses, segundo a Teoria da Atividade, são constitutivos da consciência objetal dos sujeitos, possíveis de serem identificados por meio de rede de Sentidos, que cada licenciando tece no caminho de suas significações, com base no contexto social vivido; Sentido Pessoal, profissional e acadêmico; e, pelo desenvolvimento intelectual que constitui a “atividade coletiva”. Dessa forma, entendemos que a Atividade Humana é um fluxo interno totalmente influenciado pelo meio externo, no entanto, são processos da nossa consciência social, que refratam os significados pessoais de cada indivíduo na relação com seus objetos.

Targeting Catecholamines to Develop New Drugs for Attention Deficit Hyperactivity Disorder
Authors: Jung Sung-Cherl , Cho Chang-Hwan , Kim Hye-Ji , Ko Eun-A , Ha Min-Woo , Kwon Oh-Bin
Published: December 2021

The prevalence of attention deficit hyperactivity disorder (ADHD), a developmental neuropsychiatric disorder, is high among children and adolescents. The pathogenesis of ADHD is mediated with genetic, biological, and environmental factors. Most therapeutic drugs for ADHD have so far targeted biological causes, primarily by regulating catecholaminergic neurotransmitters. However, ADHD drugs that are clinically treated have various problems in their addictiveness and drug stability; thus, it is recommended that efficacy and safety should be secured through simultaneous prescription of multiple drugs rather than a single drug treatment. Accordingly, it is necessary to develop drugs that newly target pathogenic mechanisms of ADHD. In this study, we attempt to confirm the possibility of developing new drugs by reviewing dopamine-related developmental mechanisms of neurons and their correlation with ADHD. Histone deacetylase inhibitors (HDACi) can regulate the concentration of intracellular dopamine in neurons by expressing vesicular monoamine transporter 2 and inducing the exocytosis of neurotransmitters to the synaptic cleft, thereby promoting the development of neurons and signal transmission. This cellular modulation of HDACi is expected to treat ADHD by regulating endogenous catecholamines such as dopamine. Although studies are still in the preclinical stage, HDAC inhibitors clearly have potential as a therapeutic agent with low addictiveness and high efficacy for ADHD treatment.

Published: December 2021

Soil erosion is a global environmental and economic problem that is
significantly related to land-use changes. Over the last decades, several
mountain areas in Serbia were exposed to strong human pressure caused by
winter tourism development. The largest ski center in Serbia is situated on
Kopaonik Mountain within the boundaries of Kopaonik National Park, where the
conflict between economic and conservation goals is rapidly growing. In this
study, we calculated the sedimentation and surface runoff in three
sub-basins in the area of Kopaonik ski resort for two years (1984 and 2018)
using the Soil and Water Assessment Tool (SWAT) and analyzed the changes
that occurred during the observed period. The results show an increase in
surface runoff and sediment yield in sub-basins 1 and 3 and a decrease in
sub-basin 2. The analysis of land cover change shows an expansion of
evergreen forests, appearance of barren soil and urban areas, reduction of
mixed forests and pastures, and the appearance of deciduous forests. These
findings indicate that in the area studied, the dominant processes are the
development of tourism and natural revegetation of abandoned agricultural
land. Application of remote sensing techniques and SWAT contributes to
identifying and monitoring land degradation problems and improving
conservation and management practices.
Local population analysis in the function of the protected area sustainable development

Published: December 2021

The research focus of the paper is set on the socio-economic potential of a
protected area, as a key factor and a prerequisite for its development. The
spatial framework of the research includes five settlements in the vicinity
of Special Nature Reserve ?Carska Bara? (Northern Serbia). For the purpose
of this research, they are classified into two groups, based on their
distance from the fundamental phenomenon. The demographic characteristics
analyses of the study area include basic demographic determinants such as
population structures and migration characteristics. Population data related
to the change in the number of inhabitants and the types of the total
population movement were collected and analyzed, and a comparative analysis
of the aging index was performed as well. In order to better understand the
condition of the economic structure, the economic activity, and the
structure of the active population performing occupation were analyzed by
activity sections. The current state of the social infrastructure (schools,
primary health care facilities, pharmacies, post offices, sports, and
recreation facilities) was also considered, as one of the qualities of life
indicators of the local population. The obtained results indicate an
unfavorable demographic picture of the analyzed areas. These are smaller
population areas, predominantly inhabited by population of the old age
groups. Although they are in protected areas which, in the context of
tourism, are abounding in natural potentials, but without implementing
significant steps and certain measures, no progress and improvement of the
demographic condition can be expected.
The role of Euroregions as a factor of spatial integration and regional development-the focus on the selected border area
Authors: Stankov Slobodanka , Peric Marija , Doljak Dejan , Vukovic Natalia
Published: December 2021

The political changes that affected the European area in the second half of
the 20th century conditioned the development of European countries on the
principle of Euroregions, as interesting creations of neighboring countries.
Formed along the political borders of neighboring countries, Euroregions
today play a significant role in the enlargement process of the European
Union. At the end of the 20th century, the formation of Euroregions covered
the area of the Western Balkans as well. In Podrinje, the border area of
Serbia and Bosnia and Herzegovina, the formed Euroregions have the goal of
reviving and revitalizing rural areas. Tourism, as the most important
economic activity, is integrated into the basis of the rural development of
these areas. The subject of the research is related to the analysis of the
development degree of border rural areas, under the influence of tourism.
The research problem is focused on the rural areas of ?Serbian? Podrinje.
Accordingly, the aim of this paper is to determine the change and burden of
rural border area due to the development of tourism, using the indicator of
tourist operation (I.T.O.) and the tourist function indices to measure the
degree of the development of a destination. The results of the research
indicate that three types of tourist destinations have been developed in the
studied area: destinations with almost non-existent tourist activity (< 4),
with small-scale tourist activity (4- 10), and developed and eminently
tourist destinations (40-100). The obtained results indicate that 83.3% of
the destinations in "Serbian" Podrinje are destinations with almost
non-existent tourist activity. These are the destinations where the
development of tourism does not affect the transformation of space, but the
original and preserved environment is promoted as a tourist attraction.
Accessing Cloud Data to Expand Research and Analytical Opportunities: An Example using IRS/AWS Data for Nonprofit Organizations
Authors: Wu Chengzhang , Dull Richard B.
Published: December 2021

The IRS Form 990 provides a rich set of financial and nonfinancial information about nonprofit organizations. Historically, these returns were available to researchers in PDF format, or partial data were available through information aggregators. Beginning in 2011, the forms were e-filed in an XML format, and those files are made available to the public at no monetary cost. To date over 2.6 million of these returns have been filed and are currently available online. This study uses the design science paradigm to describe the process of accessing the forms from AWS (Amazon Web Services), examining XML structures, transforming the data, and loading that data into an updatable database. The resulting database is then used to demonstrate the artifact's effectiveness through a variety of inquiries. The process extends researchers' capabilities to use newly available data to investigate accounting, governance, and other questions that were not previously feasible to consider.

Calibrating Word-Sized Graphics for Financial Accounting Applications: Evidence and Examples
Authors: Tinkelman Daniel P. , Gomaa Mohamed
Published: December 2021

We argue that, to be complete, financial reports should provide information to users about all “material” items. It is therefore desirable that all material effects in financial graphs should be visible to users. If small, word-size graphics are calibrated improperly, users may overlook visually small but numerically material effects. Prior literature does not provide adequate design guidance. We test subjects' ability to detect differing absolute and relative size effects in sparklines. We expand the concept of cognitive fit to include minimum relative and absolute visual sizes of key effects. Consistent with the legibility literature, we find accounting student participants' ability to detect patterns and anomalies over certain approximate minimum relative and absolute size thresholds is robust. Two examples illustrate how our findings on approximate relative and absolute size thresholds apply to financial accounting applications.

Published: December 2021

The study is devoted to the development of information technology for forecasting based on time series. It has been found that it is important to develop new models and forecasting methods to improve the quality of the forecast. Information technology is based on the evolutionary method of synthesis of the forecast scheme grounded on basic forecast models. The selected method allows you to consider any number of predictive models that may belong to different classes. For a given time series, the weight coefficients with which the models are included in the resulting forecast scheme are calculated by finding the solution to the optimization problem. The method of constructing the objective function for the optimization problem in the form of a linear combination of forecasting results by basic forecasting models is shown. It is proposed to find the solution to the optimization problem using a genetic algorithm. The result of the method is the forecast scheme, which is a linear combination of basic forecast models. To assess the quality of the forecast, it is suggested to use forecasting errors or forecast volatility calculated as the standard deviation. Forecast quality criteria are selected depending on the context of the task. The use of forecast volatility as a quality criterion, with repeated use of technology, will reduce the deviation of forecast values from real data. The structural scheme of information technology is developed. Structurally, information technology consists of two blocks: data processing and interpretation of the obtained values. The result of the application of the developed information technology is the production rules for determining the predicted value of the studied quantity. Experimental verification of the obtained results was performed. The problem of forecasting the number of religious organizations in Ukraine based on statistical data from 1997 to 2000 has been solved. The autoregression method and the linear regression model were chosen as the basic forecast models. Based on the results of using the developed information technology, the weights of the basic models were calculated. It is demonstrated that the obtained forecast scheme allowed to improve the average absolute percentage error and forecast volatility in comparison with the selected models. Keywords: information technology; time series; forecasting; evolutionary technologies; forecast volatility; synthesis of the forecast scheme.

Published: December 2021

Prospek geotermal di daerah Timur Ciremai berada pada aktivitas vulkanik aktif namun pencarian prospek panas bumi di area ini mengabur akibat adanya kontras antara batuan vulkanik dengan batuan sedimen. Penelitian ini mencoba mengidentifikasi area potensial panas bumi berdasarkan suhu permukaan menggunakan metode pengindraan jauh. Data yang digunakan berupa citra satelit Landsat 8 yang sudah mempunyai sensor termal yang disebut Thermal Infrared Sensor (TIRS) pada pita sensor 10 dan 11 yang dikombinasikan dengan NDVI. Hasil analisis NDVI menunjukkan bahwa daerah penelitian memiliki vegetasi dan permukaan berupa air atau awan yang lebih banyak memantulkan gelombang cahaya tampak dibandingkan gelombang infrared dengan nilai NDVI -0,75 - 0,88. Hasil analisis LST dapat diketahui bahwa suhu permukaan pada daerah tersebut memiliki nilai dalam rentang 15 °C – 31 °C. Area yang memiliki tingkat LST tinggi di antara tingkat LST yang rendah dapat diperkirakan sebagai area yang memiliki anomali. Hal ini bersesuaian dengan kerapatan vegetasi pada area tersebut yang tinggi sehingga seharusnya besar suhu permukaannya rendah bukan sebaliknya. Berdasarkan integrasi dengan data manifestasi di lapangan, maka dapat di pastikan bahwasanya terdapat beberapa anomali panas bumi pada arah tenggara dari Gunung Ciremai.
Product design for people with Rheumatoid Arthritis and its relationship with stakeholder’s expectations
Authors: De Andrade Allisson José Fernandes , Triska Ricardo
Published: December 2021

Approximately 6.2% of the Brazilian population has some disability, from which 1.3% declare to have some physical disability. Rheumatoid Arthritis (RA) is a systemic and autoimmune disease that affects about 0.4% to 1.3% of the world population, being more common in women. In advanced stages, the disease can cause severe impairment in small joints, limiting individuals' movements and impairing their independence and autonomy. Assistive Technology (AT) aims to promote actions that enable People with Disabilities or Reduced Mobility to execute their daily activities in the most normal and independent manner possible. However, studies show high rates of abandonment of AT devices for reasons generally related to the effectiveness of the product itself. Thus, this study aims to carry out data collection, organization, and analysis to understand the expectations of stakeholders about the development of new AT devices for individuals with RA. For this, the technical research procedures were segmented as follows: Phase 1 – Theoretical Foundation; Phase 2 – Selection of Target Audience and Sampling; Phase 3 – Data Survey; and Phase 4 – Data Organization and Analysis. Through the procedures adopted, it was possible to verify that there are significant differences between the expectations of stakeholders concerning the development of new AT products for individuals with RA, which can directly imply user satisfaction, consequently generating the abandonment of these devices if they do not meet the expectations.

Published: December 2021

Every year India losses the significant amount of annual crop yield due to unidentified plant diseases. The traditional method of disease detection is manual examination by either farmers or experts, which may be time-consuming and inaccurate. It is proving infeasible for many small and medium-sized farms around the world. To mitigate this issue, computer aided disease recognition model is proposed. It uses leaf image classification with the help of deep convolutional networks. In this paper, VGG16 and Resnet34 CNN was proposed to detect the plant disease. It has three processing steps namely feature extraction, downsizing image and classification. In CNN, the convolutional layer extracts the feature from plant image. The pooling layer downsizing the image. The disease classification was done in dense layer. The proposed model can recognize 38 differing types of plant diseases out of 14 different plants with the power to differentiate plant leaves from their surroundings. The performance of VGG16 and Resnet34 was compared.  The accuracy, sensitivity and specificity was taken as performance Metrix. It helps to give personalized recommendations to the farmers based on soil features, temperature and humidity

The advantages and limitations of the petrography method and the relevance of its use for the study of natural ice are reviewed in the present work. The petrographic method of ground ice study is often used for solving paleogeographic issues. The petrofabric analysis of ground ice is not only useful for descriptive purposes but, like the study of cryostructures, helps to infer growth processes and conditions. Different types of natural ice have specific features that can help us to determine ice genesis. Surface ice, such as glacier ice is often presented by foliation formed by large crystals (50-60 mm); lake ice is characterised by the upper zone of small (6 mm x 3 mm) dendritic and equigranular crystals, which change with increasing depth to large (may exceed 200 mm) columnar and prismatic crystals; segregated ice is composed by crystals forming foliation. Ground ice, such as ice wedge is presented by vertical-band appearance and small crystals (2-2.5 mm); closed-cavity ice is often distinguished by radial-ray appearance produced by elongated ice crystals; injection ice is composed by anhedral crystals, showing the movement of water; snowbank ice is presented by a high concentration of circular bubbles and small (0.1-1 mm) equigranular crystals; icing is described by foliation and mostly columnar crystals. Identification of the origin of ground ice is a complicated task for geocryology because it is difficult to distinguish different types of ground ice based on only visual explorations. The simplest way to get an ice texture pattern is by using polarized light. Distinctions between genetic types of ground ice are not always made in studies, and that can produce erroneous inferences. Petrography studies of an ice object are helpful to clarify the data interpretation, e.g., of isotopic analyses. It is particularly relevant for heterogeneous ice wedges’ study.

The study aimed to examine the change in the concentration of nitrogen dioxide due to the lockdown amid the COVID-19 pandemic in India at the district level using Sentinel-5P TROPOMI. The spatio-temporal characteristics of the tropospheric column NO2  concentration during 45 days of the lockdown were compared with the same days of 2019. Further, to model spatially varying relationships of NO2 during the lockdown period, it was given as a dependent variable whereas NO2 during the pre-lockdown period was considered as an independent variable. Results show that the mean NO2 concentration was reduced from 0.00406 mol/m2 before the lockdown (2019-03-25 to 2019-05-10) to 0.0036 mol/m2 during the lockdown period (2020-03-25 to 2020-05-10). The maximum decline of NO2 concentration was observed in Gautam Buddha Nagar and Delhi. This indicates the high level of atmospheric pollution due to the excess use of fuel in human activities. The results of the Ordinary Least Squares (OLS) method show a strong positive relationship between both variables. Positive standard residuals indicate that the concentration of NO2 has reduced more than expected as per the OLS model. The z-score (24.11) was obtained from spatial autocorrelation. It indicates that residuals are highly clustered and there is less than a 1% likelihood that this clustered pattern could be a result of a random chance. The highest decrease was observed in districts/urban agglomerations of Gautam Buddha Nagar (-40%), Delhi (-37%), Greater Bombay (-31%), Hyderabad (-29%), Faridabad (-29%), Bangalore Urban (-28%), Gandhinagar (-27%), Chennai (-27%) and Gurgaon (-26%) respectively.

This paper provides information on active layer thickness (ALT) dynamics, or seasonal thawing above permafrost, from a Circumpolar Active Layer Monitoring (CALM) site near the city of Norilsk on the Taimyr Peninsula (north-central Siberia) and the influences of meteorological and landscape properties on these dynamics under a warming climate, from 2005 to 2020. The average ALT in loamy soils at this 1 ha CALM site over the past 16 years was 96 cm, higher than previous studies from 1980s conducted at the same location, which estimated ALT to be 80 cm. Increasing mean annual air temperatures in Norilsk correspond with the average ALT increasing trend of 1 cm/year for the observation period. Active layer development depends on summer thermal and precipitation regimes, time of snowmelt, micro-landscape conditions, the cryogenic structure (ice content) of soils, soil water content leading up to the freezing period, drainage, and other factors. Differences in ALT, within various micro landscape conditions can reach 200% in each of the observation periods.
Differential possibilities of classical histological research methods for establishing the genesis of hemorrhages in the human brain substance
Authors: Garazdiuk Marta
Published: December 2021

Verification of the cause of death (CD) from ischemic cerebral infarction (ICI), hemorrhage of traumatic (GTG) and non-traumatic (GNG) genesis eliminates the violent origin of death. Very often it is difficult to diagnose the genesis of hemorrhage only macroscopically when performing an autopsy, so additional material should be selected for forensic histological examination.
Aim of the work. To develop forensic criteria for the differentiation of ICI, GTG and GNG of the brain by light microscopy of histological sections of the human brain (HB).
Material and methods. For the study were used native sections and stained histological specimens of HB from 110 corpses in the case of: death from ICI – 30 histological specimens (1 group), which were made of 30 speciments stained by the methods of Nissl and Spiel-Mayer; GNG – 30 histological samples (group 2) – 30 speciments, stained similarly to the previous group; GNG – 30 histological samples (group 3) – 30 speciments stained similarly to the previous group. Brain preparations in case of death from coronary heart disease were selected for control – 20 samples (4 groups) – 20 speciments stained by the methods of Nissl and Spiel-Mayer.
Results. Analysis of the obtained data of histological examination of morphological changes of tissue elements of the human brain with different genesis of hemorrhage did not reveal stable relationships between changes in the structure of nervous tissue and the cause of hemorrhage.
Conclusion. Given the nonspecificity of degenerative changes in the structural elements of the brain, depending on the genesis of hemorrhage, it can be concluded that morphological methods of histological preparations of the brain do not provide accurate and objective information about the genesis of hemorrhage.
Methodological approaches to the application of burns classifications in determining the severity of injuries in Ukraine

Published: December 2021

The article considers the existing classifications of thermal burns by the depth of the lesion. The analysis and comparison of different classifications among themselves is carried out. The problems that may arise in forensic medical practice in determining the severity of thermal burns, which are associated with the use of different classifications, are demonstrated. The use of different classifications of burns according to the depth of the lesion can lead to incorrect determination of the severity of injuries when compiling the "Expert Conclusion". Methodological approaches that will avoid this are presented.

The aim of the work. Elaboration of methodological approaches to the use of modern classifications of burns, which are introduced in Ukraine and in other countries, during forensic medical examinations of thermal injuries.

Materials and methods. Analysis, synthesis, comparison and analogy of printed and electronic legal documents of Ukraine, domestic and foreign forensic and medical literature on burn injury.

Results. Analysis and comparison of different modifications of burns classification by depth of injury revealed that modern classifications by combinations of numbers and letters differ from the classification of burns by depth, which is used in forensic practice in Ukraine in determining the severity of thermal injuries. The forensic expert during the examination in cases of thermal injury examines the medical records that contain information about the treatment of the victim. Victims can be treated in various medical institutions both in Ukraine and abroad. Thus, different classifications are used in the formulation of the diagnosis, which can lead to incorrect determination of the severity of the injury caused by high temperature. The result is a biased "Expert Conclusion", which may later be considered inadequate evidence in criminal proceedings. To prevent erroneous assessment of the degree of burns, the expert must find out what classification of burns is used in making a clinical diagnosis, and interpret the specified degree of burns in accordance with the gradation of burns, which regulates the activities of forensic experts.

Conclusion. At present, the «Rules of forensic determination of the severity of injuries», which were approved in Ukraine in 1995, don't provide adequate methodological support for forensic expert research, which should correspond to the current level of development of medical science and clinical practice. The introduction of the achievements of world medicine into the domestic forensic medical practice should be facilitated by modern legal documents regulating the activities of forensic medical institutions of Ukraine.
