Authors: Frizzarini Silvia Teresinha , Cargnin Claudete , Waideman Adriele Carolini , Guedes Luciane 
Published: October 2020

O trabalho objetiva analisar quais critérios de congruência são conservados no estudo de limites e tecer reflexões sobre a influência dos critérios conservados nos recortes de produções realizadas por alunos que cursam o Ensino Superior da Universidade Tecnológica Federal do Paraná. A metodologia utilizada é a análise bibliográfica dos livros utilizados por esses alunos e algumas de suas produções documentais com problemas que envolvem limites. Para isso, são utilizados os pressupostos teóricos dos registros de representação de Duval, em específico a congruência semântica, para a análise do conceito de limite. São consideradas as transformações das diferentes representações, por tratamento e conversão, das regras utilizadas no cálculo de limites, representação gráfica, aproximação numérica e representação algébrica. Os resultados apresentados foram que, apesar dos critérios conservados nos cálculos algébricos por substituição sejam matematicamente comprováveis, nos casos em que se aplica, eles são semanticamente não congruentes, ou seja, não há univocidade semântica entre as unidades significantes respectivas dos registros numérico e gráfico. Portanto, outras metodologias são necessárias para se interpretar o conceito limites de uma função, por meio de diferentes representações.

Aim: To perform a territorial comparison of the incidence rates of certain cardiovascular diseases (CVD) in the pediatric population of the city ofVoronezh.Material and Methods. The morbidity rates in the pediatric population over certain inner-city zones were assessed using a differentiated approach. This tactic was chosen taking into account historical background as a high percentage of the population (75.8% of the total population in the city district of Voronezh) was registered at particular clinics based on a territorial logic. Of these, 11 pediatric clinics in Voronezh provided care for over 160,000 children under the age of 14 years (about 79% of children residing in the city district of Voronezh) on a territorial basis. The ranking of indicators was performed using a specially designed software developed at the Voronezh State Medical University named after N.N. Burdenko. The territories at risk were identified based on the results of this analysis by the level and dynamics of morbidity in the pediatric population. Results. Cardiovascular diseases were below the top five leading disease classes and were ranked 8–9 in children in the context of overall morbidity structure in the city ofVoronezh. The study showed that the incidence of cardiovascular diseases increased in the adult population of Voronezh relative to the value for the same period analyzed last year: the growth rate in the number of medical care encounters was 14.65% with 14.05% of diagnoses established for the first time in life. The average long-term level of cardiovascular mortality in theVoronezh city district was 24.79 ± 1.40 cases per 1,000 children under 14 years of age.Conclusion. The differences, found in the morbidity rates from the individual intra-city territories provided with pediatric polyclinics, can be explained by the various factors such as the age structure of the population residing in a particular region and human resources of a medical organization including the availability of a pediatric cardiologist. Knowledge of information regarding pediatric disease incidence in certain inner-city territories allowed us to rationally optimize the resources of the urban health system to improve the availability and quality of medical care to the population, particularly the young segments, suffering from cardiovascular diseases at the pre-hospital stage.

The peculiarity of this study was not only the study of the severity of subjectively felt psychopathological manifestations and the level of depression in patients with myasthenia, data on which are found in the literature, but the features of psychological adaptive-compensatory mechanisms were first considered. The psychological characteristics of the perception of time, the level of internality and the meaning of life orientations, substantive psychopathological manifestations are studied. The article discusses the features of psychological adaptive-compensatory mechanisms in patients with myasthenia through the prism of the severity of subjectively felt psychopathological manifestations and characteristics of time, the level of internality, and life-meaning orientations. The data of modern studies of similar parameters in patients with myasthenia are given.The purpose of the study is the analysis of adaptive-compensatory psychological mechanisms in patients with myasthenia gravis, in comparison with individuals who do not have physical disorders.Materials and methods. The study involved 61 people: patients with myasthenia gravis diagnosed on the basis of clinical manifestations and the results of instrumental and laboratory tests (study of the level of antibodies to AchR MuSk) (31 people) and people without physical abnormalities (30 people). All participants were examined by experimental psychological methods: symptomatic questionnaire “SCL-90”, “Level of subjective control”, test of lifemeaning orientations, A. Beck’s depression scale, questionnaire “Semantic time differential”.Results. Patients with myasthenia gravis complain of unpleasant physical sensations, obsessive thoughts, sometimes note repeated actions and rituals. They are characterized by depressive symptoms, the presence of fears, alertness. Symptoms of the disease are assessed by them as causing great discomfort. Compared to the control group, they take less of their successes and failures, consider that their contribution to the development of family and production relations is small, these factors depend on external circumstances. In the subjective sense of the psychological characteristics of time, the present and future are defined as inactive, their course seems uneven, poorly structured, poorly predicted.Conclusion. The data obtained establish target-centered zones of psychological correction in order to stabilize the adaptive-compensatory mechanisms of patients with myasthenia gravis — this is a work aimed at correcting the self-concept and goal setting, helping the individual to better adapt to the chronic psycho-traumatic effect of the disease.

The state of cognitive deficit in subjects with combination of attention deficit hyperactivity disorder and tic hyperkinesis is among the least studied issues. Identification of the cognitive development features in children with these disorders comorbidity will help to develop and build an adequate model of rehabilitation.Purpose of the study.To study cognitive deficits in children with tic hyperkinesis (TH) in cases of comorbidity with the combined type of attention deficit disorder (ADHD).Materials and methods.404 children aged 6–10 years with a combined type of ADHD were divided into three subgroups according to the state of monoamine activity: 1st subgroup with a combination of hypofunction of dopaminergic and hyperfunction of noradrenergic systems — 120 people, 2nd subgroup with a combination of hyperfunction of noradrenergic system with a relative dopamine balance — 136 people, 3rd subgroup with indicators of monoamines within the reference values — 148 children. The control group comprised of 90 children (54 boys and 36 girls). To diagnose the level of intellectual development, Wechsler Intelligence Scale for Children was used. In each subgroup, with the known direction of monoamine activity, the Wexler test parameters were compared among ADHD groups, both with or without TG.Results.Subtests “Picture Arrangement”, “Picture Completion” and “Block Design” turned out to be sensitive to concomitant combined type of ADHD and tics in children, reflecting, respectively, enumeration, the ability to logical thinking, visual attention and hand-eye coordination. In a case of dopamine system hypofunction in children with ADHD, the addition of tics leads to the smoothing of the biochemical imbalance by increasing the activity of dopamine and thus, results in a more effective realization of logical thinking ability. The level of visual attention in children with ADHD with the addition of TH also increases, probably due to a growth of the intensity of serotonin system activity. Finally, hand-eye coordination improves with the addition of tics in cases of a shift in the balance of dopamine and noradrenergic systems.Conclusion.The data obtained are consistent with the “frontal lobe compensation hypothesis” in the part, which describes the presence of a compensatory process when tics emerge in children with combined type of ADHD. Besides, our results expand it, suggesting that not only the prefrontal cortex but also the parietal-occipital cortex participates in the adaptive process associated with spatial synthesis and analysis of information, as well as hand-eye coordination.

Sea Buckthorn (SB) juice is rich in biologically active compounds. It has considerable health benefits; thus, it can serve as functional food ingredient. The aim of this study was to determine and compare the total content of polyphenols, antioxidant capacity (FRAP), soluble solid content, pH value, β-carotene content and colour parameters (L*, a*, b*) in berry juice of cultivar 'Leikora' Sea Buckthorn (SB) (Hippophae rhamnoides L.). The treatment was made as control sample of Sea Buckthorn juice (C), and Sea Buckthorn juice with 0.5 % (P0.5); 1 % (P1); 2 % (P2) dried pomace of Sea Buckthorn. The samples were stored at room temperature for physicochemical analysis at interval of 2 months for a total period of 14 months.According to our results, the β-carotene (C to P2 was 3.71, 4.82, 5.49 and 6.52 mg 100 mL−1) as well as the antioxidant capacity of the samples increased with the growth of the pomace content. During storage, degradation occurred in the polyphenol content and antioxidant capacity, but the β-carotene content increased. The increase of the β-carotene content was 94.6 % (C) and 32.7 % (P0.5). The smaller reduction in antioxidant compounds was the higher the sample of pomace content is. The FRAP and total polyphenol values measured during storage confirm that the pomace has antioxidant effect. There is a close correlation between the two parameters, including a positive correlation (r=0.8614), which indicates that a significant part of the antioxidant capacity of buckthorn is due to the presence of different polyphenols.

За матеріалами повидільної бази даних ВО «Укрдержліспроект» станом на 01.01.2011 проведено аналіз стану рекреаційно-оздоровчих лісів, що перебувають у постійному користуванні підприємств Державного агентства лісових ресурсів України, в межах Харківської області. Виявлено, що ці ліси займають площу близько 140 тис. га (49 % від загальної площі лісів області), серед яких переважають ліси зелених зон навколо населених пунктів (90 %). Рекреаційно-оздоровчі ліси Харківщини є переважно листяними (73,5 %), серед яких переважають дубняки в умовах свіжого груду. Серед рекреаційно-оздоровчих лісів регіону домінують пристиглі та стиглі порослеві дубові насадження низької продуктивності, ефективність виконуваних ними рекреаційних функцій поступово знижується. У цих лісах потрібне проведення лісогосподарських заходів, зокрема лісовідновних рубок. Актуальною є також перспектива розширення породного складу рекреаційно-оздоровчих лісів для поліпшення їхніх санітарно-гігієнічних та естетичних властивостей.
Pine engraver beetle Ips acuminatus as a potential vector of Sphaeropsis sapinea
Authors: Davydenko K. V. , Baturkin D. O. 
Published: October 2020

The pine engraver beetle Ips acuminatus Gyll. is a potential vector of the Sphaeropsis tip blight pathogen according to Leach’s postulates. The specimens of I. acuminatus were associated with numerous fungi species, namely Sphaeropsis sapinea (Fr.) Dyko & B. Sutton and ophiostomatoid species. The association between opportunistic pathogen S. sapinea and I. acuminatus has been confirmed for 62.9 % of all branches (44 % of needle samples and 82 % of wood samples). The presence of S. sapinea in the galleries and on the surface of the beetle indicates that I. acuminatus may transport the pathogen and later introduce it into healthy trees. The bark beetle can transfer pathogenic fungus during maturation feeding on the shoots of healthy pine crowns and into the branches during making galleries.
Вплив температури на перебіг мейозу у плюсових дерев сосни звичайної з мейотичними мутаціями та перебудовами хромосом у геномах
Authors: Mytrochenko V. V. 
Published: October 2020

Досліджено вплив температури на прояв мейотичних мутацій (ds, ms43, ps + tps) та перебудов (інверсії, транслокації) в мікроспорогенезі плюсових дерев сосни звичайної. Дослідження проводили на клоновому архіві Старопетрівського лісництва ДП «Київська ЛНДС» у 2003 р. (середньодобова температура в період мейозу становила +15,8°С) та 2004 р. (+10,8°С). У фазі мейозу генеративна система більшості досліджених дерев вирізняється підвищеною чутливістю до температури навколишнього середовища. Встановлено, що експресія мутантних мей-генів ds, ps + tps зростає з підвищенням температури, а ms43 – від температурного режиму не залежить. У дерев з інверсіями частка мікроспороцитів із порушеннями збільшувалася у міру зростання температури, а з транслокацією – утворення тетравалентів відбувалося у разі зниження температури.

Introduction:This study was designed to see the knowledge, attitude and practice of barbers regarding transmission of hepatitis B, C and HIV viral infections.
Materials and Methods: Barbers from Sylhet were interviewed with a predesigned questionnaire. Positive answers for blood transfusion, syringe sharing, use of contaminated shaving instruments and unsafe sex as way of transmission were taken as correct. Statistical analysis was done using SPSS 20 version.
Result: Total 403 barbers, age from 14 years to 69 years (mean 27.11) were interviewed. In this group 232 (57.6%) had education illiterate to class five level. Among them 245 (60.3%) had income below 10 thousand per month. Blood transfusion could transmit HBV, HCV and HIV was known to 136 (33.7%), 129 (32.00%) and 247 (61.30%), contaminated syringe sharing could transmit HBV, HCV and HIV respectively was known to 131 (32.5%), 127 (31.50%) and 278 (69.0%) barbers, unsafe sex could transmit HBV, HCV and HIV was known to 166 (41.2%), 158(39.2%) and 317 (78.70%) barbers respectively and Contaminated shaving instruments could transmit HBV, HCV and HIV was known to 101 (25.1%), 96 (23.8%) and 156 (38.7%) barbers respectively. In this series 84 (20.84%) barbers answered correctly. This answers differed significantly within different level of education. Their knowledge of sterilization of shaving instruments was poor.
Conclusion: Knowledge of our barbers regarding transmission of HBV, HCV and HIV and sterilisatioin of shaving instruments are inadequate. Institutional education and structured professional training may improve their services and decrease transmission of blood borne viral diseases.

O mercado de polpa de frutas é um negócio promissor e lucrativo dentro do setor alimentício, fatores como praticidade e variedades de frutas no Brasil fez esse tipo de produto ser bastante apreciado pelo consumidor. O presente estudo teve como objetivo avaliar as características físico-químicas e microbiológicas de polpas de frutas comercializadas na Região de Carajás-PA, e comparar com o padrão estabelecido pela legislação vigente. Para tanto, foram analisados cinco sabores (abacaxi, acerola, cajá, cupuaçu e goiaba) de quatro marcas de polpas de frutas (A, B, C e D) quanto ao valor de pH, sólidos solúveis (ºBrix), acideztulável e sólidos totais. As análises microbiológicas realizadas nas polpas de diferentes marcas foram coliformes a 45°C e Salmonella sp. Os resultados obtidos para um mesmo sabor, das diferentes marcas, foram submetidos à análise de variância e comparação de médias pelo teste de Tukey a 5% de significância. Os resultados verificados nas polpas de frutas das diferentes marcas indicaram ausência de microrganismos. A marca B das diferentes polpas foi a que melhor atendeu aos padrões exigidos; e os principais parâmetros em desacordo com a legislação são o teor de sólidos solúveis totais (ºBrix) e sólidos totais, o que sugere adequação das indústrias com relação ao processamento e controle de qualidade das polpas comercializadas na Região de Carajás-PA.

Published: October 2020

O manejo inapropriado do solo é um dos fatores que podem afetar negativamente a produtividade e a qualidade dos pomares. O objetivo do trabalho foi avaliar a interferência dos sistemas de manejo do solo na produção e qualidade de pêssegos Chimarrita e Premier, em dois ciclos produtivos (2009/2010 e 2010/2011). O experimento foi implantado em delineamento experimental de blocos casualizados, com cinco repetições e seis sistemas de manejo do solo: a) solo descoberto, b) plantas espontâneas roçadas, c) cobertura morta permanente e, cobertura verde manejada com d) herbicida, e) acamada e f) roçada. A produção e produtividade das cultivares nos dois ciclos produtivos não foram afetadas pelos sistemas de manejo do solo. As características físico-químicas dos frutos foram afetadas no primeiro ciclo de produção, sendo no segundo ano alterado apenas a massa fresca do fruto e firmeza de polpa. O tratamento com cobertura morta proporcionou maior massa fresca do fruto (130,4 g) na cultivar Chimarrita com a utilização de espontâneas roçadas e menor firmeza de polpa (10,3 N) para a cultivar Premier.
