This study assesses heavy metals distribution in body parts of Labeo coubie (African carp) fromRiver Oli, in Kainji Lake National Park as pollution index of the ecosystem. Fish parts samples (gills, muscles andvertebra bone) were prepared and specifically analyzed for the levels of Pb, Cr, Zn, Cu, Fe and Cd using Atomicabsorption spectrophotometry. The concentration of metals in the samples at different concentrations ranged from0.001±0.000 μg/g for Cd to 224.87±4.07 μg/g of Fe in the fish gill. There is significant (p<0.05) differences in the Pb,Zn, Cu and Fe concentrations across the different fish parts with gills accumulated the highest levels metals while Crlevels significantly (p<0.05) differed in the fish body parts and accumulated more in the muscles (10.75±0.15 μg/g).The mean concentrations of metal elements in the fish parts had shown some distinguish connection in its distributionswith Pb and Cu; Gills > Muscles > Vertebra bones, Fe and Zinc; Gills > Vertebra bones > Muscles while Cr wasdistributed in Muscles > Gill > Vertebra bones. However, it is revealed that Labeo coubie, a euryphagus fish probablyabsorb these metals through ingestion of contaminated food or absorption by the gills and bioaccumulate in differentfish parts. It is therefore established that River Oli is contaminated with heavy metals as presence of these metals infish is an indication of its immediate environment.

Substance abuse is an intricate behavior seen to be most prevalent amongst young people across the world. This study assessed the awareness and attitude towards substance abuse among students from selected secondary schools within Sapele, Delta State, Nigeria. A cross-sectional study design was utilized among 315 students who gave informed consent. A well-structured questionnaire was used to collect data for the study from participants. Data was presented as simple percentage using descriptive statistics. The mean age of the respondents was 16.95 ± 0.09 SEM. A prevalence of substance abuse was 19.4%, which was seen more with males than the females. About 13.97% of the students had taken alcohol, 10.79% had taken tramadol, and 3.81% had taken rohypnol. School and mass media were the main sources of information on drug abuse, while peer pressure was the most predisposing influence towards substanceuse. Depression and its use as a confidence booster were main reasons given for the substance use. Adolescent substance use and abuse remains an ongoing challenge with a prevalence rate of 19.4% in this study. The study emphasizes the need for implementing drug abuse information and education in schools’ curriculum.

Published: May 2021

The present study was aimed at evaluating the clinicopathological changes due to oral administration of ethanol leaf extract of Trema orientalis (ELETO) in Jamnapari crossbred goats. The clinical manifestations, gross and histopathological changes in the major vital organs were used as indices of the toxicity. The severity of gross and microscopic changes were evaluated by scoring technique. Twenty goats weighing between 15-20kg were divided into four groups with five goats in each group in a completely randomized design. The test groups I, II, III were administered ELETO at the dosages of 0.5, 1.0 and 2.0g/kg b.wt per os/day respectively, for 14 days while, group IV served as a control. Groups II and III showed decreased appetite whereas, group III showed bilateral congestion of ocular mucous membrane, lacrimation, rectal tenesmus and a significant decrease in body weight compared to control. The main gross and microscopic changes were mild to moderate and included; engorgement of the gall bladder, congestion and icteric liver, hepatocellular degeneration, vacuolation, necrosis and renal congestion observed mainly in group III goats. The results indicate that the ELETO was hepatotoxic and nephrotoxic at continued oral doses equal to or more than 2.0g/kg b.wt in goats but no significant toxicity when used at lowers doses. Therefore, special caution should be taken when keeping goats in areas with T. orientalis.

Published: April 2021

"After statistical analysis of the database of a fire department covering eight years of consecutive incident records from January 2009 to December 2016, we developed a modelling and simulation (M&S) approach that could be replicated for fire departments across Canada. Our M&S framework involved two different simulation models running on separate platforms: (i) an Incident Generation Engine, which simulates the ‘arrival’ of emergency incidents, and (ii) a Response Simulation Model. The first model is a discrete event simulation model using CPNTools 4.0, generating inputs for the second model, which is an agent-based simulation model developed using AnyLogic. We discuss the principal elements of the two simulation models, and report on findings from our simulation experiments."

Published: April 2021

"The emergence of electrical energy is closely related to the use of power. However, the temperature of electronics could be compared to those encountered by a shuttle nose when entering the atmosphere and requires a thermal management. The technology investigated in this paper is original because able to evacuate important heat flux. The proposed system is named Biphasic Fluid Loop Mechanically Pumped (BFLMP) with a transport capacity of the thermal power up to 10 MW.m, exceeding in this way the performance of all known technologies. This paper begins with a description of the test rig of the BFLMP and its instrumentation. The second part of the paper is a detailed study of the thermo hydraulic behavior of the pump-pipe system. The proposed model is based on the bond graph theory because of its energetic approach and the multi-physics character of the studied system. A validation test is launched using water with regulation temperature at the pressurizer set at 60°C, the temperature of the secondary circuit is regulated at 37°C, a power crenel of 400 W has been applied on the evaporator. Results are discussed in a last part; the model shows up good agreement with the experimental results. The volumetric pump studied in this work is original because it was specially designed and manufactured to equip the BFLMP developed in collaboration with the research laboratory CRIStAL. This pump has been patented. Also, this centrifugal machine has been tested and has been characterized. Its performance curves are obtained and used in the model proposed in this paper. In addition, the proposed algorithm models the pump using a resistive bond graph element R."

The main objective of the study is to provide a rigorous and systematic method for modeling and verifying systematically, rigorously and effectively this type of system."
Canopy gap dynamics, disturbances, and natural regeneration patterns in a beech-dominated Hyrcanian old-growth forest
Authors: Akbari Mazdi Ramezanali , Mataji Asadollah , Fallah Asghar
Published: April 2021

Canopy gaps play a crucial role in forest dynamic processes and help preserve biodiversity, influence nutrient cycles, and maintain the complex structure of the forests. This study aimed to quantify the gap dynamics, regeneration establishment, and gap closure in a natural old-growth Hyrcanian forest in the north of Iran. We used a repeated inventory of gap size-frequency and fraction in beech (Fagus orientalis) dominant forest over a 9-year interval (2010–2019). The total gap area documented in 2010, 2016, and 2019 was 2,487, 6,890, and 8,864 m2, respectively. The gap area ranged from the smallest sizes of 139, 83, and 153 m2 to the largest sizes 906, 1,668, and 871 m2 in 2010, 2016, and 2019, respectively. Gap fraction significantly increased from 0.52%, 1.93%, and 3.7 in 2010, 2016, and 2019, respectively. The size distribution of gaps was strongly skewed to the medium class (200-500 m2), with approximately 60% of the gaps. Results revealed that total regenerations are not in correlation with gap size. Small gaps were closed within a few years through rapid horizontal canopy expansion of neighboring beech trees. The gap closure rate decreased by increasing the gap size (70% in 71 m2 to 10% in 1,600 m2). The highest density and greatest regeneration growth occurred mostly along the eastern part of gaps. The spatial distributions of regeneration density demonstrated differences in different gap size classes, which probably resulted from heterogeneity in the microenvironment within the gap and the differences in the regeneration responses to these variations. This investigation provided useful data for managing natural regenerations based on forest sustainability. The changes in gap patterns observed between 2010 and 2019 highlight the high value of repeated gap inventories for better comprehending the disturbance regeneration and dynamics of natural gaps.

Published: May 2021

Reflexivity is a central tenet of qualitative research. Engaging in self-reflexive praxis allows researchers to identify areas of tension in the research process that need to be further deconstructed. In this paper, we draw on our collective self-reflective experiences as qualitative health researchers whose scholarship is informed by critical and postcolonial feminist epistemologies to offer some guidance on how to approach the concept of insider versus outsider in the research process. Specifically, we analyze recurring methodological tensions related to positionality and outline how they were addressed. The lessons learned from our studies can be instructive to other qualitative researchers

Published: April 2021

A elite, enquanto categoria relacional vinculada à branquitude, estrutura-se por meio do racismo. Neste sentido, esse estudo objetiva analisar os discursos da elite branca local de duas cidades do interior do Nordeste a partir das categorias de raça e de políticas públicas de reparação histórica. É uma chamada a refletir e a se debruçar sobre percepções elitistas e, principalmente, sobre as diferentes formas de racismo traduzidas em violência. A pesquisa tem um delineamento qualitativo, utilizando a técnica de entrevistas semiestruturadas com comerciantes e donos(as) de imóveis, totalizando a participação de oito interlocutores. Por meio da análise de conteúdo, foram evidenciados discursos racistas e meritocráticos acerca da população negra e das políticas de reparação. Com isso, identifica-se uma forte perspectiva colonial que se traduz em justificativas e práticas de discriminação a partir da invisibilização da violência histórica contra a população negra, mantendo e reproduzindo privilégios elitistas.

Polylactide and its Composites on Various Scales of Hardness
Authors: Aworinde Abraham Kehinde , Emagbetere Eyere , Adeosun Samson Oluropo , Akinlabi Esther Titilayo
Published: April 2021

Polylactide (PLA) has become a widely applied material. Its hardness property has, however, not been a subject of intense study. This study attempts to examine the hardness values of Polylactide and its composites on ten hardness scales. Polylactide composites were developed using three reinforcements (i.e., chitosan, chitin, and titanium powders). The compositing method was the melt-blending technique. Vickers microindentation test was carried out on all the developed samples. The experimental values obtained were related to nine (9) other scales of hardness via an online reference interface. Results showed that the Brinell and Rockwell hardness scales agreed, to a large extent, with the experimental values from several studies. Hence, this work can serve as a reference material on the Brinell and Rockwell hardness values of the unreinforced and reinforced composites considered in this study. The developed materials were also represented on the Mohs scale of hardness with unreinforced PLA having the least value of hardness which corresponds to the value of gypsum on the Mohs scale while the PLA reinforced with 8.33 weight (wt.) % of titanium powder has the highest value of hardness corresponding to the value of a material in-between calcite and fluorite. The hardness values obtained on Shore scleroscope could not agree with the experimental values from various studies. Succinctly, the three particulate fillers increased the hardness properties of PLA. The results of this study would go a long way in helping industrialists and researchers in the correct applications of PLA and its composites.
Research trends in library and information science in Argentina during the first decades of the XXI century
Authors: Corda Maria Cecilia , Liberatore Gustavo
Published: May 2021

Objective. This paper aims at describing and analyzing the research lines on Library and Information Science (LIS) developed within the institutional framework of the Argentinian universities where careers in Library Science, Archival Science, and Museology are offered.

Design/Methodology/Approach. Documents presented at academic events from the Mercosur's schools were gathered, as well as former studies that address the issue. Additionally, the scientific production of researchers and academicians from the LIS field was systematized using the Publish or Perish app, considering Google Scholar as a data source.

Results/Discussion. A consolidation of the LIS field was observed, both from the contributions for the conceptual and methodological strengthening of the discipline, and from the inquiries that seek to resolve issues that arise in the professional field of libraries, archives, museums, and other information units.

Conclusions. The existence of work lines that combine topics dealt with at an international level in the field was highlighted, as well as areas of specialization, focused on local realities. It was shown that the research development and productivity are concentrated in few schools. Finally, the incipient constitution of postgraduate studies at the specialization, master's degree, and doctorate levels was addressed, which, over time, will broaden the spectrum of research carried out in the universities developing these training sections.

Originality/Value. There was no study of this type in which documentary analysis was combined with bibliometrics to reveal researchers, topics, and scientific production in the LIS field in Argentina, something not always easy to capture and address.
Peace Education and Colombia’s Efforts Against Violence: A Literature Review of Cátedra de la Paz
Authors: Morales Esteban
Published: May 2021

As long as there has been violence in organized societies, achieving peace has been a goal through different means, including education. In Colombia –a country where the national government and the guerrilla FARC reached a peace agreement–, education was set to be essential to promote a culture of peace. Accordingly, this article presents a literature review of Cátedra de la Paz, a peace education course that seeks to encourage and strengthen a culture of peace in every educational institution in Colombia. The literature review suggests that, whereas this course reveals a positive impact in the communities, a lack of institutional support –which could stem from larger-scale political and societal conflicts over what peace means and how to achieve it– trumps its implementation. Furthermore, this paper argues that –if Cátedra de la Paz or other future peace education courses aim to promote a culture of peace grounded in contextualized needs and opportunities– critical lenses towards the topics and pedagogy are necessary.
LESSON STUDY IN PRE-SERVICE PHYSICS TEACHERS’ EDUCATION: A CASE IN BRAZIL
Authors: Rodrigues Micaías Andrade , Arroio Agnaldo
Published: May 2021

Lesson study (LS) is a teaching improvement process that began in Japan more than 100 years ago. As the LS is still a new approach in the Brazilian context, this paper will discuss how it could be implemented in the pre-service physics teacher training. To accomplish this, a group was created with 6 pre-service teachers who held 11 meetings, which integrated two LS cycles. The data for this research were collected through field notes and materials produced by pre-service physics teachers. The collected data were analyzed by Bardin's content analysis. According to the results obtained, it highlighted that pre-service teachers had gaps in knowledge about the basic contents of Physics and LS showed that collective work with peers could promote reflection and enable classes that were closer to the students' reality, minimizing the difficulty and rejection by Physics in basic education, improving the students’ learning.

Operationalising children’s rights principles: an indicator framework for policy analysis
Authors: Kišūnaitė Aida , Bui Ly Hai
Published: April 2021

A pesar de los compromisos políticos de décadas de incorporar los derechos del niño en las iniciativas políticas, los instrumentos de seguimiento y evaluación basados en los derechos del niño siguen siendo inadecuados para este progreso. Como un esfuerzo por abordar esta brecha, el documento busca conceptualizar el enfoque basado en los derechos del niño y proponer su aplicación al análisis de políticas. Reconociendo a los niños como titulares de derechos y al Estado como el principal garante de deberes, el núcleo del enfoque basado en los derechos del niño es garantizar el disfrute y la realización de los derechos del niño a través de una serie de principios. El marco de evaluación propuesto en este documento se centra en la estructura legal del estado, las medidas de política y los resultados logrados en la realización y el disfrute de los derechos del niño y la evaluación del progreso de las políticas bajo las normas y principios de los derechos del niño. En consecuencia, el análisis de políticas basado en los derechos del niño está diseñado para basarse en dos conjuntos de indicadores que reflejan el compromiso político del estado y los principios de los derechos del niño.
Significados de la educación rural. Una sistematización de experiencia
Authors: Guardia López Janer
Published: April 2021

El presente artículo expone los resultados de la investigación “significados construidos por cuatro escuelas rurales del municipio de Anorí Antioquia, Colombia, sobre su experiencia de participación en el Programa Transformación Educativa para la Vida –PTEV-, período 2018 – 2020”. El diseño metodológico consideró la sistematización de experiencias como investigación interpretativa crítica (Barragán & Torres, 2017) que permitió recuperar la práctica y construir conocimiento como significación (Bickel, 2006) a partir de los sentidos asignados por los participantes a la vivencia compartida. Los resultados del estudio sugieren que los programas educativos deben trascender la didáctica instrumental en función de la didáctica como disciplina de intervención social (Landazábal & Pineda, 2010). Orientan a re-ajustar el horizonte temporal y el soporte metodológico sobre el que dichos programas fundamentan su acción. Consecuentemente, instan a re-significar la concepción de escuela y de los Proyectos Educativos Institucionales –PEI- en función de nociones sistémicas y relacionales que replanteen las bases teóricas de los programas educativos e introduzcan cambios en la estructura curricular de los centros escolares rurales. Finalmente, destacan la urgencia de hacer frente a los impactos socioambientales de los megaproyectos en el sector, garantizando la presencia de las familias campesinas en el territorio y de los niños y niñas en las escuelas rurales, esto, articulando los programas y proyectos de intervención a prácticas de gestión social y educativa más democráticas y participativas.

Acidente Vascular Cerebral (AVC) é uma doença crônica não transmissível de elevadaincidência pouco discutida pela população em geral. Este estudo objetivou analisar aqualidade do conhecimento a respeito do conceito, principais sintomas, fatores de risco etratamento do Acidente Vascular Cerebral em amostra de 180 indivíduos a partir de umquestionário online. Ademais, visou descrever a prevalência dos fatores de risco paraAcidente Vascular Cerebral na amostra e comparar a caracterização epidemiológica dosparticipantes com seus conhecimentos referidos na coleta de dados. A pesquisa descritivatransversal de abordagem epidemiológica utilizou para a coleta de dados um questionárioonline, elaborado através da plataforma Google Formulários. O questionário foi do tipoestruturado não disfarçado, contendo perguntas objetivas sobre a caracterização, etiologia, classificação, manifestações clínicas, fatores de risco e tratamento do Acidente Vascular Cerebral. A amostra caracterizou-se por maioria do sexo feminino (73,33%), com idade entre 18 e 21 anos (37,78), brancos (72,78%) e com escolaridade de nível superior (60,56%). As análises foram estratificadas pela presença (CCM) ou ausência (SCM) de comorbidades, (41,11%) e (58,89%) respectivamente. Sobre a definição de AVC, 76,11% dos indivíduos indicaram que o Acidente Vascular Cerebral se caracteriza como uma ocorrência de sintoma da função cerebral, que é a opção idealmente correta. Em relação aos fatores de risco, 172 indivíduos indicaram hipertensão arterial como fator de risco (95,56%,), seguido de histórico familiar de AVC (n=164; 91,11%), obesidade (n=137; 76,11%), tabagismo (n= 131; 72,78%) e candidíase (n= 4; 2,22%), sendo as quatro primeiras corretas. O conhecimento sobre os sintomas demonstraram 157 respostas para confusão mental (87,22%), 149 para dor de cabeça (82,78%), 139 para dificuldade para andar (77,22%), 123 para alteração visual (68,33%) e 111 para diminuição da sensibilidade (61,67%), sendo todas possíveis de ser manifestações clínicas do AVC. Por fim, a respeito das possíveis formas de tratamento do AVC isquêmico, 134 indivíduos indicaram como resposta o tratamento com remédiotrombolítico (74,44%), 129 o processo cirúrgico de trombectomia (71,67%), 90 o tratamento individualizado (50%) e apenas 5 para tratamento antidepressivo (2,78%), o qual não é utilizado no tratamento agudo do Acidente Vascular Cerebral. Dessa forma, parte significativa da amostra foi capaz de identificar corretamente o conceito, principaissintomas, fatores de risco, fatores que influenciam no prognóstico e possíveis formas detratamento do AVC. Entretanto, apenas 10,56% se sentiram confiantes sobre seus osconhecimentos referente ao AVC.

Published: May 2021

A doença renal crônica (DRC) tem fatores de risco muito frequentes entre a populaçãobrasileira e mundial, como a diabetes mellitus, a hipertensão arterial, o tabagismo e a obesidade. Nos últimos anos o número de pacientes em falência renal aumentou, fazendo com que mais pessoas necessitem do serviço de hemodiálise, o que diminui a qualidade de vida e expõe os pacientes a diferentes intercorrências, como infecções. As infecções associadas ao cateter/bacteremia podem estar relacionadas ao não cumprimento das normas para controle de infecção da ANVISA e ao mau uso dos cateteres para acessos venosos, desrespeitando seu tempo adequado de uso. Assim, realizou-se pesquisa transversal, qualitativa e quantitativa, com análise de fichas do Centro de Controle de Infecção Hospitalar (CCIH), as quais obtinham informações extraídas dos prontuários eexames laboratoriais de pacientes internados na Unidade de Hemodiálise do Hospital Regional da Asa Norte (HRAN) e acompanhados durante todo o período de internação entre janeiro e dezembro de 2019, no HRAN. O objetivo principal do trabalho foi identificar os pacientes em hemodiálise que desenvolveram infecção e investigar os principais fatores associados ao desenvolvimento de bacteremia nos pacientes, apontando os principais agentes etiológicos destas infecções. Porém, a indisponibilidade de hemocultura no hospital durante o período analisado impossibilitou a verificação da etiologia das infecções, assim como estimulou o uso empírico dos antimicrobianos, acarretando no uso de múltiplos destes. A hemocultura, de acordo com os critérios da ANVISA, é essencial no diagnóstico de bacteremia, tendo isso prejudicado o estudo. Contudo, o cumprimento de suas regras para controle de infecção é imprescindível para evitar infecções relacionadas à hemodiálise.

Authors: Santos de Oliveira Gabriella , De Oliveira Melo Julia , Beraldo Goulart Borges Haubert Nádia Juliana
Published: May 2021

A incidência de hipertensão arterial no recém-nascido a termo varia entre 0,2 a 3%. A magnitude deste intervalo reflete a dificuldade de definir a hipertensão neonatal decorrente dos fatores: ausência de estudos prospectivos de larga escala que determinem valores de referência universalmente aceitos, variabilidade das técnicas e condições de medição da pressão arterial e influência nos valores normais de pressão arterial da idade gestacional, peso à nascença, sexo, antecedentes patológicos e o uso de medicações maternas. Objetivos: Obter percentis de pressão arterial sistólica, diastólica e média em neonatos saudáveis a termo , entre a 1ª e a 2ª hora de vida, utilizando um dispositivo oscilométrico de aferição, calculando uma escala de pressão arterial sistólica e diastólica média ao nascer; além de correlacionar o valor da pressão arterial com peso ao nascimento, idade gestacional, sexo e via de parto. Métodos: Foi realizado um estudo prospectivo de coorte de dados de prontuários do Hospital Santa Lúcia - Brasília/DF. A aferição da PA foi executada entre os primeiros 15 e 30 minutos de vida através da oscilometria automática MX-600 GE, seguindo protocolo padrão de assistência do hospital. Foram incluídos RNs a termo, sem patologias, que não necessitaram de internação na unidade de terapia intensiva neonatal. Os critérios de Exclusão foram recém nascidos prematuros ou a termo que evoluíram com desconforto respiratório que necessitaram de internação e portadores de malformações maiores. Resultados: Foram avaliadas as aferições de 800 neonatos. A via preferencial de parto na amostra estudada foi a cesárea, 85,8% dos partos, e o sexo masculino foi o mais prevalente 50,9%. As médias obtidas foram de 64,89 ± 10,7 mmHg para a pressão arterial sistólica e 37,60 ± 11,7 no sexo masculino e 66,46 ± 10,9 PA sistólica e 39,52 ± 12,3 PA diastólica para feminino. A frequência cardíaca média foi de 152,86 ± 13,5 bpm masculino e 155,56 ± 12,8 feminino. Além disso, 85,1% dos RN foram classificados como adequados para idade gestacional e 97,9% das aferições foram realizadas no membro superior direito. Conclusões: O presente estudo apesar das limitações de a não aferição por um mesma pessoa, ter uma proporção tão grande de RN nascidos de parto cesáreo que podem interferir na hemodinâmica fetal, fortalece o cuidado neonatal uma vez que permite a segurança deconhecer uma curva nacional de pressão arterial e frequência cardíaca semelhante a curvas americanas e europeias.

A chorus of scholarly voices has echoed the significance of spiritual intelligence in organizational settings. This paper provides fresh insights by investigating the relationship between spiritual intelligence (SI) and workplace outcomes using David King's four-factor Spiritual Intelligence
SelfReport Inventory (SISRI-24). The study was conducted in Nigeria, a sub-Saharan African country, using a sample of 216 employees of a private university selected in a non- probabilistic sample. There was a significant relationship between SI and workplace outcomes such as job performance,
job commitment, and job satisfaction. However, the effects of the dimensions of SI on workplace outcomes are varied. These results bring to fore the existence of possible variations in the meaning and dimensions of spiritual intelligence; and their effects on workplace outcomes across contexts.
As spiritual intelligence correlates with positive employee outcomes, organizations should invest in discovering, developing, and deploying this domain of intelligence.

Published: April 2021

In recent years, biometric recognition based systems have become widespread. One of these is wrist-based recognition systems. In this study, wrist print based recognition system was developed by using near infrared (NIR) camera. Totally 220 NIR camera images taken from 10 for each both hands of 11 people. The obtained data set is allocated 70% (154 images) for training and 30% (66 images) for testing. The wrist regions are labeled on the training set images. Data sets were created with two different labeling methods. In the first data set, only the wrist regions were labeled and it was aimed to segment the wrist region from the image. In the second data set, the wrist images were labeled according to 22 classes and these classes were tried to be predicted. The labeled data was trained with YOLOV2 architecture supported by ResNet50 one of the deep neural network models. The trained model was tested with the remaining 30% of the data set. In the test process, the wrist region was determined in the NIR images with the trained model. As a results of the study, it was seen that the wrist regions were correctly detected in all first data set test images and the mean value of obtained similarity rates was 95.26%. In the test results of the second dataset, 92.43% classification success was obtained. Therefore, it can be said that the deep learning architectures ResNet and YOLO are effective in the segmentation of the wrist region.

Published: April 2021

Micro Electro-Mechanical System (MEMS) based devices offer innovative approaches in sensor technologies with the advantages of high efficiency and miniaturization. The most important stage in the development of new generation MEMS-based devices is the design and optimization stage. However, device design and optimization processes are developed in a laboratory by empirical approaches. This causes time loss and creates an unnecessary waste of resources. In this study, it is aimed to design and analyze two gas sensors based on ZnO and TiO2 sensing layers. Electro-thermal analysis of the sensor structure was carried out at room temperature and high temperature (294,15K-573,15K) and heat transfer parameters were compared. According to the simulation results, it is obtained that, as the applied temperature increases to the sensor, the temperature over the sensing layer increases linearly. It is compatible with the literature. The temperature on the ZnO surface increases to three times the TiO2 surface temperature. The heat transfer results obtained will be used as a guide for device design and optimization in future works. In this way, as a result of numerical analysis, a MEMS-based device will be produced with high accuracy. Thus, time and resources will be saved.

The article presents the data on the characteristic features of lipoprotein metabolism and the level of vasoactive endothelial factors in children with primary and symptomatic arterial hypotension. Dyslipidemia in the first group of patients is characterized by an increase in low-density lipoprotein cholesterol, apolipoprotein B100, the atherogenicity coefficient, the ApoLP atherogenicity index, a high concentration of nitric oxide in case of low levels of high-density lipoprotein cholesterol and ApoLP A1. In children with chronic gastroduodenal pathology and symptomatic arterial hypotension, the above disorders of lipoprotein metabolism and endothelial function are accompanied by an increased content of total cholesterol and bradykinin. These data suggest that in children with primary and symptomatic arterial hypotension, conditions for the formation of the initial atherosclerotic process are created due to the predominance of the pro-atherogenic Apo B100 transporter protein over the anti-atherogenic Apo A1, as well as due to a significant increase in nitric oxide and endothelial dysfunction.
