Authors: Yapıcı-Öksüzoğlu Ayşegül
Published: July 2020

Background and Study Aim. The aim of this study was to investigate the effect of 6 weeks theraband training on respiratory parameters, upper extremity muscle strength and 50-100m swimming performance in swimming athletes.

Material and Methods. Totally 12 male swimmers participated voluntarily and were divided into two groups as control group (n=6) and experimental group (n=6). Control group did only swimming training, experimental group did theraband exercises in addition to swimming exercises. Respiratory parameters, upper extremity anaerobic performance, shoulder extension/flexion strength and swimming performance were measured. Mann Whitney-U Test was used to determine the differences between two groups. Wilcoxon Test was used to determine intra-group differences.

Results. There was no statistically significant difference between the pre and post-test values of respiratory parameters, anaerobic performance values and swimming measurements of the experimental groups (p>0.05). There was a statistically significant difference between shoulder extension and flexion values (p<0.05). As for the statistical results between the pre and post-test values of the control group, no significant difference was found in any of the variables (p>0.05). There was a statistically significant difference between the post-test values ​​of the experimental and control groups shoulder extension and flexion values (p<0.05). There was no statistically significant difference between respiratory function parameters, anaerobic performance values and 50-100m swimming degrees (p>0.05).

Conclusions. As a result of the findings, it can be said that theraband training which is done as a land work with swimming training leads to positive effects in the upper extremity muscle strength and swimming performance development of youth swimmers.

Published: July 2020

This paper presents a seven-dimensional ordinary differential equation of mathematical model of zika virus between humans and mosquitoes population with non-linear forces of infection in form of saturated incidence rate. Vertical transmission is introduced into the model. These incidence
rates produce antibodies in response to the presence of parasite-causing zika virus in both human and mosquito populations. The existence of region where the model is epidemiologically feasible is established (invariant set) and the positivity of the models is also established. The basic properties
of the model are determined including the reproduction number of both cases, R0 and R0 |p=q=0 R respectively. Stability analysis of the disease-free equilibrium is investigated via the threshold parameter (reproduction number R0
|p=q=0) obtained using the next generation matrix technique. The special case model results shown that the disease-free equilibrium is locally asymptotical stable at threshold parameter less than unity and unstable at threshold parameter greater than unity. Under specific conditions
on the model parameters, the global dynamics of the special case model around the equilibra are explored using Lyapunov functions. For a threshold parameter less than unity, the disease-free equilibrium is globally asymptotically stable. While the endemic equilibrium is shows to be globally
asymptotically stable at threshold parameter greater than unity. Numerical simulations are carried out to confirm the analytic results and explore the possible behavior of the formulated model. The result shows that, horizontal and vertical transmission contributes a higher percentage of infected
individuals in the population than only horizontal transmission.

Published: July 2020

In fuzzy mathematics fuzzy system reliability can be analysed by fuzzy sets. We can use various types of fuzzy sets for that analyzing the fuzzy system reliability but here we specially used intuitionistic fuzzy set theory. At first, TrIFNs and their arithmetic operations are introduced.
Expressions for computing the fuzzy reliability of a series system, parallel system, series-parallel and parallel-series system following TrIFNs have been described. Here an imprecise failure to start of a truck is taken. To compute the imprecise failure of the above said system, failure of
each component of the systems is represented by Trapezoidal Intuitionistic Fuzzy Number. This process can be utilise to measure the failure is various aspects like portfolio in stock market etc. The numerical expression also calculated and presented in this paper for the failure to start of
a truck using TrIFN.

Published: July 2020

We have reviewed the proof[1] of a conjecture posted in the Online Encyclopedia of Integer Sequences (OEIS)[2], which states that there are exactly five positive integers that can be represented in more than one way as the sum of non-negative integral powers of
2 and 3. The case for both powers being positive follows from a theorem of Bennett. We have also devised alternative logics to the elementary methods applied in the original paper “On duplicate representations as 2x+3y for nonnegative integers x and y”[1]
to prove the case where zero exponents are allowed. Besides, we have included a nominal program towards the end, that verifies the statement of the conjecture.
USE OF LINEAR ALGEBRA AND PARTIAL DERIVATIVES IN SUPERVISED LEARNING (ARTIFICIAL INTELLIGENCE AND MACHINE LEARNING)
Authors: Misra Prerana , Mukherjee Avik , Pyne Anish
Published: July 2020

When we talk about new technologies and the advancement in the field of Computer Science, the first thing that comes to our mind is Artificial Intelligence and Machine Learning. Artificial Intelligence has seen resurgence in the 21st century because of its ability to mimic
functions done by human intelligence like “problem solving” and “learning”. It is slowly becoming the area of interest of the new generation because of its modern capabilities which even human intelligence struggle to perform like competing at highest level in strategic
game systems, intelligent routing, operating cars autonomously and simulations. Artificial Intelligence may look easy but there are several tools involved in making it successful. One of the main tool is “Statistical Methods”. Linear algebra and Partial Differential Equations have
become the base of this field. The objective of our paper is to throw light on how Statistical Methods and Mathematical optimization provide the base for the working of Supervised Learning. Over years, algorithms inspired by Partial Differential Equations (PDE) and Linear Algebra have had
an immense impact on many processing and autonomously performed tasks that involve speech, image and video data. Image processing tasks and intelligent routing done using PDE models has lead to ground-breaking contributions. The reinterpretation of many modern machine capabilities like artificial
neural networks through PDE lens has been creating multiple celebrated approaches that benefit a vast area. In this paper, we have established some working of these methods in different subfields of Artificial Intelligence. Guided by well-established theories we demonstrate new insights and
algorithms for Supervised Learning and demonstrate the competitiveness of different numerical experiments used in the sub-fields. Not only will we see the wide application of Artificial intelligence but also its ability to slowly replace human works leading to unemployment which are part of
its limitation. This research will provide wider insights into the multiple mathematical processes which acts as roots to make the field of Computer Science interesting and successful.
Sources of black Sigatoka resistance in wild banana diploids

Published: July 2020

Abstract Black Sigatoka (black leaf streak disease) is caused by the fungus Mycosphaerella fijiensisMorelet. This phytopathogen colonizes banana leaves, resulting in reduced photosynthesis and decreased productivity. Fungicide applications are useful to control black Sigatoka; however, they increase production costs and can have adverse environmental and health impacts. The cultivation of resistant cultivars is regarded as a more economically viable option. The objective of this study was to perform diploid phenotyping in a set of wild banana accessions to identify resistant genotypes. A total of 31 accessions (30 with AA genome and one with AB genome) were phenotyped based on the presence of disease symptoms using a scoring scale. The area under the disease progress curve (AUDPC), the disease severity index (DI), and the disease severity increase index (DII) were estimated. The DII variable proved to be efficient in identifying banana accessions with black Sigatoka resistance. Likewise, the selection index for ranking accessions with moderate black Sigatoka resistance allowed us to identify those genotypes with the highest quantitative resistance. Five diploid accessions (Krasan Saichon, Zebrina, Birmanie, Nº 118, and Tuu Gia) were found to be resistant to this fungal disease; eight accessions (PA Rayong, Pisang Cici, Malaccensis 1, 028003- 01, Microcarpa, Pisang Lidi, Lilin, and Malbut) were moderately resistant.
Protected cultivation of ‘BH-65’, ‘Siluet’, ‘Sensation’,‘Intenzza’ and ‘Red Lady’ papaya cultivars in South East Spain
Authors: Salinas Irene , Pinillos Virginia , Hueso Juan José , Cuevas Julián
Published: July 2020

Abstract Papaya (Carica papaya L.) is a tropical fruit crop of rapid growth and early yielding. In recent years, papaya cultivation has extended to subtropical regions due to its commercial interest. In South East Spain, protected cultivation is, however, mandatory to ensure the optimal development of the crop. Even more, to assure profitability, the selection of plant material well adapted to the structural constrains and the climatic conditions inside greenhouses is essential. With this objective, different papaya cultivars with diverse geographical origin, characteristics and pedigree have been compared. ‘BH-65’, ‘Siluet’, ‘Sensation’, ‘Intenzza’ and ‘Red Lady’ papaya cultivars were thus grown under a plastic greenhouse in Almería, SE Spain and their growth, phenology, yield and fruit quality compared in a 21-month production cycle. The results showed that ‘Siluet’ and ‘Sensation’ papayas are well-adapted to greenhouse protected cultivation, produce high yield, and optimal fruit quality for long and short distance markets. Cultivars like ‘BH-65’ could be of interest for low-height greenhouses due to its reduced plant vigor and high fruit quality. However, ‘BH-65’ yield is low. According to the European consumer preferences, the cultivation of ‘Siluet’ and ‘Sensation’ is recommended, for the harsh conditions the greenhouse cultivation imposes in subtropics.

Published: July 2020

RESUMO Dez éguas, sem raça definida, foram submetidas a avaliações ultrassonográficas durante o intervalo interovulatório, avaliando-se folículos ≥ 5mm. Cinco éguas foram tratadas com 500mg de r-bST no primeiro e no 14º dia pós-ovulação (grupo GT), e as demais com soro fisiológico (grupo GC). Quando o folículo dominante atingiu diâmetro ≥ 40mm, foram induzidas com hCG e inseminadas 24 horas após, sendo submetidas à coleta de embrião seis dias após a ovulação. Os dados foram agrupados de acordo com o diâmetro do folículo dominante nas fases de emergência, divergência, dominância, pré-ovulatória, indução, inseminação e ovulação. Todas as éguas foram usadas duas vezes, no mesmo grupo. O GT apresentou crescimento folicular precoce para as fases de emergência, divergência, dominância e pré-ovulatória, assim como para o seu maior folículo subordinado, que cresceu mais cedo. As taxas de recuperação foram de 90% (GC) e 70% (GT), em 16 estruturas coletadas, obtendo-se uma não fecundada e um blastocisto inicial para o grupo GC; os demais, no estágio de mórula, apresentaram comportamento semelhante entre os grupos. Conclui-se que a r-bST influencia a dinâmica folicular de éguas, levando a uma antecipação do desenvolvimento folicular, que pode ser utilizada para encurtar o ciclo estral.

ABSTRACT The objective for this study was to evaluate the supplementation with different non-fibrous carbohydrate (NFC) sources for grazing dairy cows in diets with high or low concentrations of rumen undegradable protein (RUP). Twelve multiparous cows averaging 30kg/d of milk production and 45±23 days in milk in a 4x4 Latin square design with 2 × 2 factorial arrangement were used. The difference in NFC content of the diets was achieved using ground corn (GC) or dried citrus pulp (DCP). Dietary RUP was altered by the partial replacement of soybean meal (LRUP) by roasted whole soybean and corn gluten meal (HRUP). Greater dry matter intake (DMI) was observed in DCP treatments compared to GC treatments (19.2 and 17.7kg/day of DM, respectively). Milk fat concentration was lower for LRUP treatments (3.4%) when compared to HRUP (3.6%). The milk protein concentration was greater for GC treatments (2.9%) in relation to DCP treatments (2.8%). Lower milk ureic nitrogen was observed when DCP diets were fed compared to those with GC (17.8 and 21.2mg/dL, respectively). The use of DCP as CNF source increased dry matter intake as well as milk fat concentration, although no differences in milk production were observed for RUP level.

RESUMO Objetivou-se testar a vitrificação de ovários de camundongos do ICTB/Fiocruz. Inicialmente, fez-se coleta e maturação in vitro dos oócitos de ovários a fresco e vitrificados, bem como avaliação de estruturas no cultivo embrionário, pós-fertilização in vitro. Fêmeas B6D2F1 foram eutanasiadas para remoção dos ovários (n=60) e divididas em três grupos: grupo 1 (n=30 animais) - oócito de ovários vitrificados, maturados e fertilizados in vitro (120 fragmentos); grupo 2 (n=15) (controle 1) - oócitos coletados a fresco, maturados e fertilizados in vitro; e grupo 3 (n=15) (controle 2) - oócitos maturados in vivo e fertilizados in vitro. A técnica foi verificada no desenvolvimento embrionário in vitro, que foi avaliado pelo teste de qui-quadrado (BioStat 5.0). Recuperaram-se 123, 224 e 328 oócitos nos G1, G2 e G3, respectivamente. Observaram-se diferenças significativas nas taxas de clivagem às 24 horas (embriões ≥ 2 células) entre G1 (8%) e G2 (32%) (P<0,1) e G1 e G3 (49%) (P<0,05), mas não entre G2 e G3 (P>0,05). Para blastocistos, às 96 horas, os grupos G1, G2 e G3 apresentaram, respectivamente, 6%, 11% e 46%, diferindo significativamente entre eles (P<0,05). A vitrificação de ovários, a maturação oocitária e a fertilização in vitro são alternativas para a produção de embriões de camundongos in vitro.

RESUMO Nos sistemas de produção, os produtos naturais vêm se destacando na substituição a produtos sintéticos, dentre eles podemos ressaltar os óleos vegetais ricos em ácido graxos poli-insaturados (PUFA), que são conhecidos, popularmente, por seus efeitos benéficos. Dessa forma, o objetivo com este trabalho foi avaliar os efeitos da suplementação dos óleos de pequi (Caryocar brasiliense) e girassol (Helianthus annus) sobre parâmetros fisiológicos em leitões na fase de creche. Foram utilizados 180 leitões alojados em granja comercial, distribuídos em três grupos (n=60) conforme suplementação alimentar: óleo de pequi, óleo de girassol e controle negativo. Amostras de sangue e o peso dos animais foram obtidos nos intervalos de quatro trocas de rações da fase de creche para avaliação do desempenho, da resposta inflamatória, do perfil lipídico e do “status” oxidativo. Os parâmetros fisiológicos mensurados demonstraram que os óleos interferiram positivamente na resposta inflamatória sistêmica, por meio dos leucócitos totais e da relação neutrófilo/linfócito (P<0,05); no equilíbrio oxidante-antioxidante, por mensuração de óxido nítrico e do malondialdeído (P<0,05); e no metabolismo lipídico, com a avaliação de colesterol total e triglicérides (P<0,05). Por outro lado, esses óleos vegetais interferiram no ganho de peso e no consumo de ração (P<0,05). Assim, concluí-se que a suplementação com óleos de pequi e girassol melhora a saúde dos animais, mas tem impacto negativo no desempenho zootécnico de leitões na fase de creche.

ABSTRACT Bacterial resistance is a reality in both human and veterinary health, it limits the therapeutic arsenal and raises the costs of the patient’s treatment. A dog with signs of cystitis received treatment with 5mg/kg enrofloxacin at three consecutive times, with low effectiveness. The presence of urethral uroliths was identified and urohydropulsion was done. The animal presented a new obstruction, for which a cystotomy was performed, but continued with signs of infection. Uroculture and antimicrobial susceptibility test were then performed. Escherichia coli was identified, which was resistant to 13 antibiotics, being sensitive only to piperacillin-tazobactam and amikacin. In the screening test for β-lactamase, the production of ESβL was detected. The qPCR indicated the presence of the bla CTXm, bla DHA, bla OXA, bla IMP, bla TEM, bla GIM, bla SIM, bla SPM and bla SME genes, which may lead to a phenotypic resistance profile for ampicillin, amoxicillin-clavulanate, aztreonam, cefepime cefoxitin, cefuroxime, ceftazidime, ceftriaxone, imipenem, and piperacillin-tazobactam. This case reaffirms the value that laboratory analysis adds to the diagnosis and treatment of cystitis and urolithiasis, which can define the direction of evolution of the prognosis and the speed at which the patient's health will be restored.

RESUMO O herpesvírus equídeo 1 (EHV-1) apresenta distribuição mundial e causa graves prejuízos à equideocultura. É agente de surtos de doença respiratória, reprodutiva e neurológica, em equídeos jovens e adultos. A glicoproteína D (gD) do envelope viral é essencial para ligação e penetração em células permissivas e direcionamento do sistema imunológico do hospedeiro, induz respostas imunes humorais e celulares, sendo um antígeno apropriado para ser utilizado em vacinas e imunodiagnóstico. O objetivo deste trabalho foi expressar e caracterizar a gD do EHV-1 em Pichia pastoris para posterior utilização como antígeno em técnicas de imunodiagnóstico e formulação de vacinas recombinantes. Uma sequência de DNA que codifica uma forma truncada da gDEHV-1 foi clonada no vetor pPICZαA de expressão em P. pastoris. Obteve-se uma proteína de ~41 kDa, como esperado. A proteína apresentou glicosilação entre 4 kDa e 16 kDa, demonstrada por deglicosilação enzimática. A proteína recombinante foi caracterizada antigenicamente e imunogenicamente por Western blot, utilizando-se anticorpos policlonais equinos anti-EHV-1, e por ELISA indireto em modelo murino, demonstrando que a gD recombinante manteve epítopos similares aos da proteína nativa. Esses resultados sugerem que a gDEHV-1 é um antígeno promissor para uso como imunobiológico no controle do EHV-1.

RESUMO O milho é a principal fonte de energia nas dietas animais. Em algumas regiões brasileiras, sua disponibilidade, principalmente na entressafra, é insuficiente para atender à demanda, fazendo com que seu preço se eleve. Neste estudo, objetivou-se avaliar a substituição do milho pelo sorgo sobre o desempenho zootécnico e a digestibilidade em coelhos. Foram utilizados 60 animais machos da raça Nova Zelândia Branco, divididos em três tratamentos: ração base milho (TM); ração base sorgo (TS) e ração base 50% de milho + 50% de sorgo (TMS). No ensaio de desempenho, avaliou-se ganho de peso (GP), consumo de ração (CR), conversão alimentar (CA), coeficientes de digestibilidade da matéria seca (CDMS), proteína bruta (CDPB), fibra em detergente neutro (CDFDN) e fibra em detergente ácido (CDFDA). Observou-se que o CRM, a CA e o GPM não foram afetados pela substituição do milho pelo sorgo, nos níveis de 50% e 100%. Os resultados de digestibilidade demonstraram maiores CDPB e CDFDN na ração base milho, não havendo diferenças entre os demais parâmetros estudados. O sorgo com baixo teor de tanino pode ser usado nas rações de crescimento de coelhos em níveis de substituição de 50% ou 100% da participação do milho, sem prejuízos para o desempenho zootécnico e a digestibilidade.

ABSTRACT A captive 7-year-old male bush dog (Speothos venaticus) was diagnosed with lymphoma affecting the kidneys, adrenal glands, liver, and spleen. The animal developed renal failure and was euthanized due to poor prognosis. Grossly, both kidneys were enlarged with multiple nodules. Histologically, the neoplasm was an infiltrative and poorly demarcated round cell tumor. Two morphologically distinct cell populations were observed, smaller cells with a lymphocytic morphology, and another population of larger and pleomorphic cells. Most of the smaller cell population, approximately 40% of the population within the neoplasm, were CD3 positive. Neoplastic cells were CD45, CD11d, and granzime B positive, and negative for CD20, CD79a, PAX5, CD163, and myeloperoxidase. This is the first reported case of lymphoma in a bush dog. This report demonstrated the suitability of several cell surface markers for differential diagnosis of round cell tumors in this species.

ABSTRACT Nabumetone is used to reduce the pain and inflammation in rheumatoid arthritis. In the current study, immunomodulatory effect of Nabumetone is investigated in mice. The control group was administered normal saline orally as placebo. Nabumetone was administered orally via gavage in two treatment groups at 14mg/kg.b.w. doses and 28mg/kgb.w., respectively. Haemagglutination (HA) assay, Jerne hemolytic plaque and mice lethality assays were applied. In HA assay, the titer was significantly decreased in Nabumetone treatment groups (P< 0.001). In Jerne hemolytic plaque formation assay, there was a significant reduction (P< 0.001) in number of plaques in Nabumetone treated groups when compared with control. In mice lethality assay, there was a significant difference in mortality ratio of mice in control and Nabumetone treated groups (P< 0.001). Therefore, it is concluded that Nabumetone suppresses the humoral immune response in mice.
Clusters espaciais de “agriculturalização” no meio rural de alguns estados brasileiros
Authors: Stege Alysson Luiz , Bacha Carlos José Caetano
Published: July 2020

Resumo: O meio rural brasileiro tem se caracterizado, em especial nas últimas quatro décadas, pela diminuição da sua população, diminuição do total de pessoas ocupadas na agropecuária e pelo crescimento de atividades não agrícolas. No entanto, esses processos não são homogêneos entre os estados brasileiros, parecendo haver regiões ainda mais agrícolas do que outras. Neste contexto, o presente artigo tem como objetivo propor e estimar, usando a análise fatorial, um indicador de intensidade das atividades agrícolas (chamado de indicador de “agriculturalização”), além de apresentar a distribuição espacial deste indicador. Para tanto, utiliza-se a análise exploratória de dados espaciais considerando os estados Paraná, São Paulo, Mato Grosso do Sul, Mato Grosso e Goiás, tomando-se como referência os anos de 2000 e 2010. Esses estados foram escolhidos pela sua proximidade física, pela sua importância na agropecuária nacional e por compartilharem atividades agropecuárias similares. Diagnosticou-se a presença de aglomerações espaciais do tipo Alto-Alto para o indicador de “agriculturalização”. Essas aglomerações espaciais podem ser explicadas pela presença dos complexos agroindustriais existentes em tais regiões e pelo próprio efeito espacial do transbordamento da atividade agrícola.
Para além da racionalidade: outras dimensões da ação entre organizações familiares de produção agrícola: uma discussão a partir da realidade de famílias de agricultores no sul de Santa Catarina
Authors: Boehs Carlos Gabriel Eggert , Seifert René Eugênio
Published: July 2020

Resumo: A discussão a respeito da racionalidade que orienta a ação em organizações tem enfatizado a dualidade entre as racionalidades instrumental e substantiva. “Para além da racionalidade...”, busca compreender nos significados compartilhados entre organizações familiares de agricultores outras dimensões da ação nos modos de organizar a atividade de produção agrícola. O estudo de caráter qualitativo foi realizado com 13 famílias em localidades de descendentes de imigrantes no Sul do Brasil. Recorremos à observação das organizações familiares em que seus integrantes compartilham atividades de produção agrícola em pequenas propriedades rurais no sul do estado de Santa Catarina. Nos três modos de organizar a produção agrícola identificados como integrado, semi-integrado e não integrado, os significados compartilhados apontaram indícios da ação orientada pelo afeto e tradição, indo além das dimensões da ação orientada pela racionalidade instrumental e/ ou de caráter substantivo. Observou-se que as relações afetivas e as práticas produtivas baseadas em tradições assumem papel significativo nos modos de organizar e estão associados ao caráter substantivo das relações sociais, segundo os referenciais teóricos adotados. Conclui-se que seja relevante que essas dimensões da ação, renegadas na discussão sobre racionalidades, sejam consideradas entre organizações familiares vinculadas a atividades de produção agrícola.

Resumo: Este artigo objetiva classificar os municípios do MATOPIBA com base em um conjunto de variáveis socioeconômicas, com destaque para as características agrícolas. Além disso, propõe-se a decompor o crescimento do VAB setorial no período 2010-2015, no sentido de identificar grupos de municípios com vantagens competitivas e de especialização. Para tanto, foram utilizadas conjuntamente a análise de cluster e o shift-share com base em informações do IBGE, RAIS e PNUD. A aplicação do shift-share foi realizada com base nos grupos formados pela análise de cluster, o que permite maior integração dos métodos. Os principais resultados mostram a formação de cinco grupos, sendo apenas um deles considerado incipiente do ponto de vista do dinamismo da agropecuária. Os resultados do shift-share apontam que esse grupo considerado incipiente foi o único a apresentar VLT negativa e não apresentar vantagem competitiva nem ser especializado na agropecuária.

RESUMO: Objetivos: Estimar a prevalência de sonolência diurna excessiva (SDE) e os fatores associados a ela em adolescentes da coorte de nascimentos de São Luís (MA). Método: Estudo transversal realizado com 2.514 adolescentes com idade de 18 e 19 anos. Utilizou-se abordagem hierarquizada e calculou-se a razão de prevalências utilizando regressão de Poisson com ajuste robusto da variância. Foram estudadas características sociodemográficas (sexo, cor, classe econômica, ocupação), hábitos de vida (lazer, fumo, álcool, uso de drogas ilícitas, consumo de café e de bebidas energéticas, prática de atividade física, adiposidade corporal, tempo de tela, depressão) e fatores relacionados ao sono. Resultados: A prevalência de SDE foi de 36,8%. Sexo feminino (razão de prevalência - RP = 1,33; intervalo de confiança de 95% - IC95% 1,19 - 1,49), alto risco de consumo de bebidas alcoólicas (RP = 1,26; IC95% 1,09 - 1,46), episódio depressivo maior atual (RP = 1,26; IC95% 1,08 - 1,46), escore de 10 a 18 de alterações do sono (RP = 1,43; IC95% 1,10 - 1,85) e escore de 5 a 7 da disfunção durante o dia (RP = 2,51; IC95% 2,06 - 3,07) foram os fatores de risco para SDE. A classe econômica D/E foi fator de proteção para SDE (RP = 0,47; IC95% 0,27 - 0,85). Conclusão: Mais de um terço dos adolescentes apresentou SDE, e aqueles com maiores riscos precisam melhorar seus hábitos de vida e de sono para que não tenham mais SDE, visando melhorar sua qualidade de vida.

Abstract Siganids are the most important marine fish distributed along the African coast. Therefore, the current study aimed to investigate parasite fauna infects one of the most important mariculture fish species in the Red Sea, the Rabbit fish Siganus rivulatus. One acanthocephalan species has been isolated from the posterior region of fish intestine, belonging to the Neoechinorhynchidae family, and named as Neoechinorhynchus macrospinosus Amin & Nahhas, 1994 based on its morphological and morphometric features. In order to determine the accurate taxonomic position of this acanthocephalan species, molecular phylogenetic analysis was carried out based on the partial sequences of 18S rDNA gene region. The obtained data revealed that this species was associated with a close identity ˃71% for other species belonging to the Neoechinorhynchidae family. In addition, the recovered species deeply embedded in the Neoechinorhynchus genus, closely related to the previously described Neoechinorhynchus sp., N. mexicoensis, and N. golvani with identity percent of 95.14, 93.59, 93.59%, respectively. Therefore, the present study provide a better understanding about the taxonomic status of N. macrospinosus based on 18S rDNA that can be useful for achieving a proper assessment of biodiversity.

The search for bone reconstruction materials and methods is an ongoing challenge. The aim of this review is to systemically search the available literature concerning the clinical performance of eggshell as a substitute material in guided bone regeneration in oral surgery. Five databases (PubMed, Cochrane, Web of Science, Scopus, and Embase) were searched up to February 2020. Clinical trials that used eggshell as a bone substitute material were included. Animal and in vivo studies were excluded. ROBINS-I was used to evaluate the risk of bias. A total of 840 studies were retrieved, out of which 55 full-text articles were screened. Five studies were finally included: one study showed critical and four serious risk of bias. A total of 74 patients and 88 intervention sites were included in the five studies. Clinical and radiological evaluation showed complete healing during the follow-ups. Statistically significant radiological and clinical evidence of new bone formation was achieved for socket preservation, grafting after third molar extraction, and cystic/apicectomy grafting. One patient with complications was reported. Histological analysis and micro computed tomography confirmed that it promotes bone regeneration. A comparison with synthetic hydroxyapatite showed similar healing characteristics. Within the limitations of the included studies, eggshell can be safely and efficiently used in guided bone regeneration procedures, but more research is needed to completely evaluate the full potential of this material.

Authors: Gilbert Naomi , Pound Helena , W Wilhelm Steven
Published: July 2020

This extraction protocol uses a modified filter extraction method and bead-beating technique. This verison uses a technique to attempt to increase the biomass recovered from low-biomass samples by cutting out the filter from the sterivex unit with a sterile razor blade or scalpel. The filter is then placed directly into the bead bashing lysis tube and is homogenized with the starting solution. The protocol has been tested and used on oligotrophic seawater samples that contain a low amount of biomass.

The article gives a classification of groups, its types and subspecies. The goal is: to determine the degree of influence of the group on human opinion. The tasks are defined: to study scientific theories on the problem of group influence, to conduct an experiment to determine the level of conformity of students in grades 10, to analyze the experimental data, to draw conclusions based on the results of the study. It has been suggested that under pressure from a group a person can change his mind. Two forms of conformism are distinguished: compliance and approval. The positive influence of the group on the formation of personality development is noted. It shows how surveys and debates were conducted. In order to prove that the group is able to influence the opinion of a person, an experiment was conducted. The work shows the results that can be used in modern psychology to study the phenomenon of "conformity", and practically in informing the people who participated in the experiment, on the topic of some group phenomena. It is concluded that the influence of the group is not homogeneous, it cannot be only positive or only negative, it depends on the group and on the conditions in which the person fell.

The article is devoted to the problem of increasing the educational potential of summer camps. The proposed approach to its solution is based on ideas about the children's and adult collective as an event community of participants in joint creative activity. The theoretical foundations of the design of the educational process in the conditions of a summer camp are described, its results are described as new competencies not achieved in the traditional class-lesson teaching system. The idea of individualization of the educational process is disclosed as the leading methodological basis of the summer camp project in the event-activity format. The educational event is presented as a design unit of the educational process. Sociocultural practices, creatively mastered by the participants of the camp shift, are characterized. The principles of their development by the example of the art of theater and cinema are disclosed. The logic of building sociocultural practice as a sequence of certain phases and immersions is described.
Cultural-Historical Activity Theory in the Framework of the “Functional Paradigm”
Authors: Leontiev D.A.
Published: July 2020

The aim of the paper is to highlight the peculiarity of the present state of the Cultural-historical activity theory (CHAT) in psychology, as compared to previous periods of its development in the general context of theory development in psychology. The author sees this peculiarity in that CHAT exemplifies an anti-Aristotelian paradigm which suggests that the actual functioning of living systems cannot be fully deduced from a priori existing morphological and psychological structures. This emphasis unites CHAT with two other influential approaches to the explanation of human conduct, existentialism and the systems approach to autoregulating systems, which can be found from early cybernetics to synergetics and the theory of complexity of our own day. Although they each occupied marginal positions in human sciences in the middle of the last century, all three approaches now find themselves articulating the same message in different words; basic similarities between them allow us to speak of their confluence into what may be called the functional paradigm. The functional paradigm states the primacy of the process, actual functioning, activity, or existence, the absoluteness of uncertainty and changeability, and thus seems to be the most relevant paradigm for the challenges of our times.
Using CHAT to Address the Nature of Scientific Knowledge Aspects on a PD-Program for Greek Science Teachers as a Cycle of Expansive Learning
Authors: Koumara A. , Plakitsi K.
Published: July 2020

A Science Teachers’ Professional Development (PD) Program on Nature of Scientific Knowledge (NOSK) aspects is designed, implemented and evaluated, based on the cycle of expansive learning. A needs analysis showed that NOSK is not explicitly included in Greek Science classes and its integration might be a solution to students’ indifference towards them (questioning phase). A relevant literature review highlights three approaches to teach NOSK: through History of Science (HOS), Scientific Inquiry (SI) and Socio-scientific Issues (SSI). The PD-program includes all three, in that order, to provide the 49 participant-teachers alternative paths to embed NOSK in more school science units, designed according to the community of trainees’ Cultural-Historical characteristics and the Principles of Adult Education (analysis and modelling phases). Teachers examine and test the new model (4th phase) through a voluntary assignment to design and present a lesson plan to the plenary. The implementation phase consists of teaching in the classroom and a 5th meeting, finishing with a 6th meeting (reflecting phase). Arisen contradictions are dealt to evolve the whole activity system. Works for evaluation are included in all phases. Results to that point show that the PD-program is successful.
Contemporary Adolescence through the Prism of the Cultural-Historical Theory: on the Issue of Experimenting with Roles
Authors: Rubtsova O.V.
Published: July 2020

The article focuses on the main aspects of understanding adolescence in the framework of the Cultural-Historical Theory. Such concepts as new formations, social situation of development and leading activity are discussed in relation to this age period. It is argued that controversies about the content of development in adolescence are due to the fact that so far no “ideal form” has been clearly indicated for this age. An attempt is made to discuss a little-known text by L.S. Vygotsky – “Concrete human psychology” – where the issue of social roles and the importance of investigating them in adolescence was highlighted. L.S. Vygotsky interpreted the notion of role as a key mechanism, responsible for the regulation of higher mental functions in various social interactions. For a number of reasons – particularly, historical – the concept of role has long remained almost neglected in Russian psychology. Thus, the article draws attention to the issue of role development in adolescence and focuses on the problem of experimenting with roles as a particular system of activities during this age period.
L.S. Vygotsky’s Ideas in the Clinical Psychology
Authors: Tkhostov A.S.
Published: July 2020

The present article discusses possible perspective trends of the development of the cultural-historical approach in the context of clinical psychology. This puts forward the thesis about the development of man in ontogeny as a result of his interaction with cultural environment which causes the transformation of natural mental functions into higher mental ones and the formation of the whole range of psychopathological abnormalities. It also discusses the voluntary regulation of higher mental functions, the determination of involuntariness and postvoluntariness of functions, the internalization of actions, the differentiation of affect and emotion (incl. as a higher mental function), the “cultural” socialization of non-mental functions (sexual, sleep, excretion) and the inconsistency of natural and “cultural” entity in a human. This paper confirms the statement that the basis of the development of man in ontogenesis is the emergence of subjectness like all the forms of higher activity through the encounter with cultural restrictions and requirements. It suggests extending the concept of “higher” functions by means of including physiological and bodily functions. The latter acquire the characteristics of higher mental functions during the socialization: the voluntary regulation, hierarchical structure and control. This considers the phenomena of alienation, conversion and dissociative disorders and voluntariness as a result of the complication and restructuring of natural functions. It also suggest trends for further investigations.
