An empirical study on the potential of land resources utilization in urban agglomeration development zones based on combination analysis
Authors: Miao Jianjun , Lu Qian
Published: June 2021

To alleviate the contradiction between human and land caused by the limitation of land resources and the irreversibility of land use in the development zone of urban agglomeration, 24 indexes were selected from four aspects: land use status, resource security, economic feasibility, and social acceptability to establish the level evaluation index system for the sustainable use of land resources in Baoding high-tech zone; also, the combination weighting method was used to determine the development level. The index weight of land resource utilization potential in the development zone was established. The subjective and objective linear combination was also established to obtain the proportion of subjective and objective. The multi-factor comprehensive evaluation model was used to evaluate the sustainable utilization degree of land in the high-tech zone. The comprehensive analysis of land-intensive use potential was made from five aspects: expansion potential, structure potential, intensity potential, management potential, and the number of years of land available; the analysis of the limiting factors and the combination of these factors of the land in the development zone was made to obtain the natural index after the renovation, and the natural quality potential of the cultivated land renovation was obtained according to the difference of the natural index before and after the renovation. The empirical results show that the high-tech zone’s land-use rationality index is relatively high during 2014-2018. During the evaluation period, the index continued to rise; the high-tech zone's resource security score was low, and there was no change during the evaluation period, which is basically at a low level. During the five years, the high-tech zone’s land-use sustainability has experienced the fluctuation process of first rising and then declining, which is in the stage of medium sustainable development. In the future, the potential for improvement is enormous. The prospect of the high-tech zone’s exploitable land structure is small, and the land structure is relatively reasonable, which is in line with the development orientation of the high-tech site. But the industrial land intensity in the zone also has a specific potential for excavation. The high-value areas of the natural quality potential of the land improvement in the high-tech site are mainly distributed in the west, northeast, and a few in the north and south.

Introduction: The use of clinical cases in simulated environments allows for a more realistic approach to the simulated health condition, which results in a more effective training experience for students, as they are immersed in situations they may encounter in their professional practice. Objective: To determine the face validity of a low back pain clinical case as a clinical simulation tool in the training of physical therapy students. Materials and methods: Study conducted to determine the face validity of a low back pain clinical case presented to physical therapy students. The case has 9 items, which were evaluated by 5 expert raters. Agreement between raters regarding the pertinence, relevance, coherence, clarity, and sufficiency of the case was established using the Fleiss’ Kappa coefficient. Results: Fleiss’ Kappa for the simulated case was 0.67 (substantial agreement), and for items 1, 2, 4, and 9 was 0.97, 1.0, 0.89, and 1.0, respectively (almost perfect agreement). Furthermore, the percentage of case comprehensibility (9 items) was 95.2. Conclusion: The face validity of the low back pain clinical case was confirmed, so its use in clinical simulation practices in the physical therapy programs offered by the Universidad de La Sabana and Universidad de Boyacá in Colombia is valid.

Published: June 2021

Introduction: Quality of work life (QWL) and health-related quality of life (HRQOL) determine health, social participation and productivity indices of women working in the informal economy. Objectives: To establish the relationship between QWL and HRQOL in women workers in informal economies from the commune 9 of Cali, Colombia. Materials and methods: Analytical and correlational cross-sectional study conducted in 2019 in 48 in women working in the informal economy who were administered the Quality of Life at Work (CVT-GOHISALO)” and the Health-Related Quality of Life-HRQOL (SF-36) questionnaires. The correlation between the dimensions of both instruments was established using the Spearman’s correlation coefficient (weak: rho=0.1-0.3; moderate: rho=0.31-0.6; strong: rho=0.61-0.9, and perfect: rho=0.9-1.0), considering a significance level of p<0.05. Results: There is dissatisfaction in 5 dimensions of the CVT-GOHISALO questionnaire, with the highest levels of dissatisfaction found in personal development (97.91%) and well-being achieved through work (95.83%). In the SF-36 questionnaire, the mean score was low in both the physical and mental summary components (45.89.3 and 44.712.9, respectively). A moderate positive and statistically significant correlation was observed between the overall score of the CVT-GOHISALO scale and the physical summary component of the SF-36 questionnaire (rho=0.419; p=0.004) and the four dimensions of this component (p<0.05). Conclusion: The lower the QWL, the lower the HRQOL. Therefore, it is necessary to implement comprehensive public health programs in Cali considering work-related and social aspects that impact the personal development and well-being of the people working in the informal economy.
Effect of newly developed interspecific hybrid rootstocks on mineral nutrient composition and fruit quality in tomato (Solanum lycopersicum L.)
Authors: Kabas A. , Celik I.
Published: June 2021

Tomato (Solanum lycopersicum L.) is one of the important vegetables in the world due to large production area and consumer interest. Biotic and abiotic stresses have negative effect on tomato production. Utilisation of rootstocks conferring resistance to biotic stresses can be considered as the most effective and environment friendly solution in tomato production to overcome this problem. Although wild tomato species is a good rootstock candidate due to its resistance to multiple plant diseases, effects of wild tomato species as rootstock on mineral nutrient composition and fruit quality are not clear. In the present study, effects of interspecific hybrids derived from two wild tomato species (Solanum habrochaites and Solanum penellii) as rootstock on tomato fruit mineral nutrient composition (phosphor (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu)) and fruit quality traits (soluble solids content (SSC), pH, percent titratable acidity (TA), and lycopene content) were evaluated. In the study, Amaron, Armstrong, and Arazi commercial rootstocks were used as control and AK0004 F1 (candidate tomato hybrid) was used as a source of scion. As result, only lycopene content was affected by different rootstocks. S. penellii was found to be with more potential for lycopene content. For mineral nutrient composition, all hybrids and controls had similar contents of potassium, phosphor, calcium, and magnesium. Manganese and copper contents decreased in all plants. S. habrochaites had more potential regarding nitrogen, iron, and zinc contens than S. penellii. This is the first study to evaluate two interspecific hybrids derived from S. habrochaites and S. penellii, and the results might be useful to understand effects of rootstocks derived from wild tomato species on mineral nutrient content and fruit quality.

Authors: Zemlyanko Victoria , Kuragina Nadezhda , Sagalaev Vadim
Published: June 2021

The article for the first time provides a consolidated list of mushrooms of Volgograd region used in cosmetology due to the presence of biologically active substances in their composition, for example, the polysaccharide glucuronoxylomannan. These compounds have immunostimulating, radioprotective, antiinflammatory, antioxidant and anti-allergenic effects. Thanks to this, masks and creams containing these substances tone and restore the skin, while lotions and tonics strengthen the hair structure. The inventory of mycobiota was carried out using the route method. Each route was about 10 km long. The mushrooms found in laboratory conditions were identified by the microscopic analysis of the samples using modern methods of light microscopy and a standard set of chemical reagents (5% KOH alkali solution, Meltzer’s reagent). MIKMED-5 light microscope was used to study the microscopic structures and determine the samples. As a result of research in 2018–2020, 8 species of macromycetes used in cosmetology were identified in the mycobiota of the region: Amanita muscaria (L.), Calvatia gigantea (Batsch) Lloyd, Ganoderma lucidum (Curtis) P. Karst., Grifola frondosa (Dicks.) Gray, Inonotus obliquus (Fr.) Pilát, Phallus impudicus L., Trametes versicolor (L.) Lloyd, Tremella mesenterica Retz. Their extracts are widely used in the cosmetic industry by various brands, in particular, Venets Sibiri, Etude House, Sabai Thai Authentic SPA, Briogeo, Dr. Ceuracle, Nollam Lab, D’Ran, Pulanna, BioAqua, Von-U, Secrets Lan, The Skin House. The following species are regularly found in the study area: mushroom Ganoderma lucidum, which grows only on a living tree Quercus robur L.; Trametes versicolor – on stumps, dead trunks and branches of Populus alba L., P. nigra L.; Tremella mesenterica – on dead branches and branches of weakened trees Populus alba, P. nigra.

Objective: Teaching aids like chalkboard and power point (PPT) have commonly been used in anatomy teaching. With an increasing number of medical seats and introduction of competency-based curriculum, PPT is being preferred. The present study aimed at obtaining the views of medical students on these two teaching aids in learning Anatomy. Methods: It was a prospective, cross-sectional, questionnaire-based study conducted on medical students of First, second and final professional of a Government Medical College in North India. Students’ perception was assessed on the basis of a questionnaire in Likert scale. Likert scale 4 and 5 were considered favorable responses. McNemar’s test was used for statistical analysis. Results: The questionnaires were distributed to 420 students but 412 students participated in study. There were 164 males and 248 females. Students perceived that PPT offered significantly (p value <0.001) better visibility of lecture content, more clarity of the diagrams, structural relations and demonstration of applied aspects as compared to chalkboard. However, chalkboard was preferred over PPT by a significantly higher number of students (p value <0.001) as it enhances the ability to take notes and copy diagrams, develop better understanding of topic, provides better opportunity for student-teacher interaction, stimulates interest in the subject and enhances overall satisfaction and effectiveness of lecture delivery. Conclusion: The present study, based on students’ responses, highlights the areas of strength of chalkboard and PPT and provides a guide for the teachers for an integrated and appropriate use of both teaching aids for effective lecture delivery. KEY WORDS: Anatomy teaching, Lecture delivery, Chalkboard, Power Point, Medical education.
Briquetting of porous alumina-containing materials with organic binders
Authors: Aksenova V. V. , Alimbaev S. A. , Pavlov A. V. , Mustafin R. M.
Published: June 2021

Waste from corundum production in the form of porous alumina sludge is a promising material for providing ferrous metallurgy with cheap alumina-containing slag-formers. However, the direct feeding of the pulverized materials to the steelmaking furnace generally results in a significant carryover of such materials with waste gases. This paper considers the possibility of making briquettes from porous sludge of corundum production by cold briquetting using various common binders (molasses, cement, powder based on polyacrylamide, emulsion based on polyvinyl acetate). A comparison of the features of cold briquetting of powdered porous materials (slimes from the production of electrocorundum) and dispersed crystalline materials (fines of chrome ore) was made. Experiments were carried out to determine the impact strength of briquettes on different binder (“cold” strength) and tests to determine the “hot” strength (by the “thermal shock” test method). The authors have determined the consumption of the binder required to obtain satisfactory characteristics of briquettes from corundum slimes and from chrome ore fines. A technique has been developed and a mechanism for the binding of particles of loose and crystalline materials has been determined during briquetting using polyacrylamide powder. The destruction of a briquette of loose materials occurs mainly along the grains of the most porous material, and briquettes of crystalline materials are destroyed along the boundaries of the grains glued with a binder. For porous materials, the binder consumption increases more than twice as compared to briquetting on the same binder crystalline bodies of a fine fraction, and the binder must necessarily impregnate the entire volume of the porous material.
The process of establishment of Roma elite. The case of Cluj.
Authors: Geambașu Réka
Published: June 2021

In Romania, the political leaders of the Roma community and the main actors from civil organizations face a particular situation. The legitimization of their leadership position ought to come neither from Roma population, nor from the non-n-Roma, but from the political elite of the majority-state who might accept or reject them as partners of political dialogue, as legitimate representatives of the Roma population. The Romanian political actors decide who or whose circle will be considered the legitimate delegate of the Roma, their attitude constituting the major determinant of the Roma elite configuration. Roma issues are thus defined from above, by outsiders who circumscribe the social space at the disposal of Roma leaders, mark their public discourse and delimit the area of their initiatives. The study of Geambaşuşu Réka sheds light on this subject by presenting the case of Cluj.
Transylvanian youth organizations from the perspective of organisational sociology
Authors: Barna Gergely
Published: June 2021

This paper gives a sociological analysis of Transylvanian Hungarian youth organizations. The author, Gergely Barna – consultant of the Executive Presidium of the Democratic Alliance of Hungarians in Romania – attempts to describe the functions and characteristics of these groups from the perspective of organizational sociology, and to reveal the sociological characteristics of the dimensions determining this sphere. One of his main conclusions is that the organizational sphere of the youth is constituted by loose networks, but the communication between the organizations that form this network is very strong. The structure of the network is a hierarchical one, with conciliatory boards on the different levels and national umbrella organizations on the top. However, the network is more dense at the local level, with cooperations and partnerships with other organizations and institutions – especially with “grown-up” civil organizations, the churches and the DAHR

Rural problems. On the economic, social, and political concerns of rural space
Authors: Juhász Pál
Published: June 2021

Examining current problems of rural regions in Hungary, the author of the study calls the attention on the anachronism in the notion of traditional "rural society". Village societies have opened up due to the more common functionally differentiated extra-village relations, the widening tracks of mobility among the various settlements, because of the more specific life conduct aspects as well as the disintegration of local public sphere. The study deals with present-day issues of such defined "rural space", making use of the sociological, demographic and economic analyses of the past years and of the conclusions of programming experiments in smaller and larger regions
Differentiation of food spoilage yeast strains of the Yarrowia group by microsatellite polymerase chain reaction fingerprinting
Authors: Nagy Edina Szandra
Published: June 2021

Yarrowia lipolytica is a frequently reported food spoilage yeast which occurs mainly in meat and milk products. Besides its detrimental role in the food spoilage it has many favourable properties. This yeast also has been developed as a production host for a large variety of biotechnological applications. Some species of the Yarrowia group cannot be differentiated by conventional methods based on phenotypic characteristics, so it is probable that not only Yarrowia lipolytica, but also other species of the Yarrowia group contribute to food spoilage or can have a beneficial role in the industry. A relatively fast, easy and low-cost but reliable method would be useful to differentiate and identify these species properly. Microsatellite PCR fingerprinting method is commonly used for the discrimination of species or strains within species, it is also applied for the identification of yeast species and in many yeast diversity studies, however, its reliability can be queried. The aim of this study was to assess the reliability of microsatellite PCR fingerprinting using (GAC)5 primer in the differentiation and identification of the yeast strains of the Yarrowia group by clustering them using microsatellite-PCR fingerprinting, then identifying them by sequencing the D1/D2 regions of the LSU rDNA of one or a few selected representatives of each cluster. Two hundred and nineteen yeast strains of the Yarrowia group were examined. Using this molecular biological method, yeast strains of the Yarrowia group from raw meat, raw milk, cheese and cottage cheese were assigned to seven species The food spoilage yeast strains of the Yarrowia group can be successfully differentiated by using microsatellite PCR fingerprinting method using (GAC)5 primer, even their identity, thus their diversity can be assessed.
Принципы справедливой мобильности как основной ответ на глобальные кризисы. Рецензия на книгу Мими Шеллер «Справедливая мобильность: политика перемещения в эпоху крайностей»
Authors: Герасименко Артем
Published: June 2021

Книга Мими Шеллер «Справедливая мобильность: политика перемещения в эпоху крайностей» посвящена политическим и этическим аспектам современных политик мобильности и предлагает список принципов, основываясь на которых можно было бы сделать эти политики более справедливыми в отношении ущемленных сейчас групп. За описанием основных глобальных вызовов следуют главы, в которых мобильность и справедливость рассматриваются через различную оптику: телесную, инфраструктурную, миграционную и климатическую. Концепции мобильности рассматриваются в контексте перемещений людей, ресурсов и информации. Симптоматичные явления в этих сферах оцениваются с точки зрения их влияния в масштабе города, страны или планеты. По итогам широкого обзора практик Шеллер предлагает набор из 28 принципов, следование которым будет способствовать установлению более справедливых режимов мобильности в рассмотренных ей сферах. Принципы носят в целом прикладной характер, однако подразумевают глубокое переосмысление таких устоявшихся сфер, как международный туризм, логистика энергетических ресурсов и регулирование офшорных зон. Однако при обращении к книге стоит учитывать, что издана она была в 2018 году, а материалы собирались в предшествующие публикации годы, то есть заметно раньше событий 2020 года, которые добавили проблеме глобализации еще и ярко выраженный эпидемиологический аспект.
Ложь, наглая ложь, автономные транспортные средства, совместная мобильность и перспективы городского транспорта
Authors: Карри Грэм
Published: June 2021

Статья посвящена критике распространенных дискурсов об автоматизированных (беспилотных) транспортных средствах и совместной (шеринговой) мобильности, согласно которым в будущем эти группы технологий будут доминировать в сфере транспорта и вытеснят общественный транспорт. Автор подробно разбирает ложные тезисы в основе каждого из этих дискурсов и показывает, что даваемые ими обещания необоснованны или даже противоречат фактам. Ключевое из них — решение проблемы перегруженности городских дорог. Только общественный транспорт благодаря высокой заполняемости может эффективно использовать дорожное пространство, в то время как совместная мобильность чаще всего не подразумевает совместные поездки, а значит, и повышение заполняемости автомобилей. В заключение автор намечает перспективные тренды в сфере общественного транспорта — в частности, синтез элементов организации разных видов транспорта и дальнейшее внедрение шеринга и автоматизации.
On demand: адаптивные маршруты общественного транспорта

Published: June 2021

Статья посвящена адаптивному общественному транспорту и принципам его работы. Предполагается, что шаттлы разной вместительности перевозят пассажиров по запросу, без фиксированных остановок с возможностью корректировать маршрут. Маршрут строится на основе многофакторной модели, цель которой — минимизация значений определенных параметров: пройденное шаттлом расстояние, время ожидания и время в пути для пассажира. Описывается механизм балансировки этих параметров. Приводятся данные по эксплуатации маршрута общественного транспорта на базе гибких маршрутов по запросу в городе Иннополис в период с июня 2018-го по январь 2020 года. Представлены результаты сравнительного моделирования транспортных систем разной степени гибкости на примере конкретной дорожной сети: при одинаковых заданных параметрах по числу транспортных средств и пассажиропотоку авторы сравнили технико-экономические показатели и параметры качества сервиса маршрутных систем разной степени гибкости. В рамках модели доказана эффективность сочетания адаптивных маршрутов разной степени гибкости. Принцип сочетания маршрутов: часть транспортных средств выделяется на обслуживание хорошо прогнозируемых потоков пассажиров с допуском небольших отклонений от основного маршрута, остальные же транспортные средства размещаются в районе функционирования сервиса без ограничений по маршруту следования и графику движения, перемещаясь в те районы и на те направления, которые становятся более востребованными в течение суток.
Bradford Protein Assay v1
Authors: Dungan Ashley
Published: June 2021

To measure the relative amount of total (holobiont) or host (just anemone) protein concentration in anemone tissue we use the Bradford assay with bovine serum albumin (BSA) as a standard (Hoadley et al., 2015; Patel and Bielmyer-Fraser, 2015; Siddiqui and Bielmyer-Fraser, 2015; Siddiqui et al., 2015; Duckworth et al., 2017). Total protein samples are derived from whole animal homogenate, whilst host protein samples have Symbiodinaceae cells removed via centrifugation. After collection of each protein aliquot, samples were flash frozen and stored at -20°C. Quantification was completed less than one month after preservation. Protein content of thawed, rehomogenized samples was determined using a microplate reader to detect changes in absorption of Coomassie dye saturated samples at 595 nm. The dye exists in three forms: cationic (red), neutral (green), and anionic (blue) (Compton and Jones 1985). Under acidic conditions, the dye is predominantly in the doubly protonated red cationic form (Amax = 470 nm). However, when the dye binds to protein, it is converted to a stable unprotonated blue form (Amax = 595 nm) (Reisner et al. 1975, Fazekes de St. Groth et al. 1963, Sedmack and Grossberg 1977). It is this blue protein-dye form that is detected at 595 nm in the assay using a spectrophotometer or microplate reader.

Authors: Lemos George Azevedo , Monteiro Jade Gama , Lima Fernando José Camello de
Published: June 2021

RESUMO: O ensino da anatomia humana é fundamental para os cursos da área da saúde e biológicas, mas enfrenta várias dificuldades como redução de carga-horária, turmas grandes e escassez de material cadavérico. Contudo a aplicação de metodologias ativas pode ajudar na resolução destes desafios. Desta forma, objetivou-se relatar a experiência na aplicação de uma atividade educativa pautada nas metodologias ativas para ensino de anatomia humana, bem como demonstrar a sua eficácia a partir da análise do desempenho cognitivo dos discentes. Trata-se de um estudo do tipo quali-quantitativo no qual foi relatada a aplicação de uma atividade de ensino denominada Expoanato, desenvolvida na disciplina de anatomia humana do curso de Licenciatura em Ciências Biológicas da Universidade Federal de Alagoas (UFAL). Ao todo, participaram 17 discentes. Para verificar o desempenho cognitivo, as notas obtidas na primeira avaliação (antes da atividade Expoanato) e da segunda avaliação (após a atividade) foram comparadas através de teste t pareado, com nível de significância de 5%. Foi possível demonstrar que a atividade Expoanato foi promissora ao estimular o trabalho em grupo, criatividade, pesquisa e revisão dos assuntos ministrados. Além disso, demonstrou-se que as notas obtidas na segunda avaliação foram estatisticamente superiores às notas da primeira avaliação. Portanto, conclui-se que a atividade Expoanato, foi importante no processo de ensino e aprendizagem em anatomia humana no curso avaliado. Cabe aos docentes e às instituições de ensino superior (IESs) a readequação dos modelos de aprendizagem, os quais precisam deixar de ser centrados no professor e passem a estimular a autonomia, criatividade e senso crítico dos discentes.

Published: June 2021

RESUMO: Empoasca kraemeri (Hemiptera: Cicadellidae) é uma praga da cultura da batata doce. Seu controle demanda de aplicações de inseticidas sintéticos, o que causa o surgimento de resistência da praga a esses produtos e contaminação do ambiente. Desta forma, o uso de óleos essenciais apresenta-se como uma alternativa para o controle do inseto. Contudo o presente trabalho teve como objetivo avaliar a bioatividade do óleo de Neem sobre E. kraemeri. Foi avaliada a bioatividade do óleo de Neem sobre E. kraemeri em condições de laboratório. Para constatação do efeito folhas de Ipomea batatas foram pulverizados nas concentrações 6,0; 3,0; 1,5; 0,75 e 0,25 ul L-1 fornecidas a adultos. As testemunhas foram pulverizadas com água destilada. O deloneamento foi inteiramente casualizado com seis tratamentos e cinco repetições com vinte insetos por folhas. O experimento foi mantido, em laboratório, a 25 ± 2°C; UR de 50 ± 10% e fotofase de 12. O extrato causou mortalidade dos adultos reduzindo a sobrevivência de E. kraemeri. Houve mortalidade de 70% a 100%, demonstrando a ação de contato do composto e seu potencial para controle da cigarrinha. Diante dos resultados obtidos, foi possível concluir que, o óleo de Neem ocasionou significativa mortalidade sobre os adultos de Cigarrinha E. kraemeri.

Para responder a essa indagação, optamos por uma abordagem quanti-qualitativa, com o foco no levantamento bibliográfico. A escolha do período mencionado deu-se considerando a possibilidade de após cinco anos da criação e da instituição do Estatuto do Idoso- Lei 10.741de 2003 -, que mencionamos seus artigos 3º, 20º, 21º e 25º a educação, de um modo geral para esse segmento, mesmo sem referência, a EJA, a modalidade responsável pela educação de jovens, adultos e idosos, no contexto da Educação Básica. O estudo apontou que no período estudado há uma carência enorme no número de produções científicas que retratam o idoso na EJA, tendo em vista que as políticas públicas de educação para o idoso apresentam-se de forma, ainda, precária no Brasil, e, principalmente, quando se articula a EJA. Essa carência transparece de forma contundente e pouco discutida, mesmo com o avanço do aparato jurídico.

RESUMO: A busca por uma vida mais saudável pressupõe, entre outras condições, um local para as famílias viverem num ambiente sustentável com qualidade de vida. Assim, o objetivo desse trabalho foi identificar o destino dado aos resíduos sólidos nas propriedades rurais das famílias de alunos da Escola Estadual de Ensino Fundamental Medianeira, Ajuricaba/RS. A pesquisa também teve o intuito de coletar sugestões das famílias sobre o que a administração municipal poderia fazer para solucionar ou amenizar o problema do descarte incorreto de resíduos no espaço rural. Quanto à forma de abordagem, caracteriza-se como qualitativa e entre os instrumentos utilizados para obtenção de dados e informações estão os questionários, as pesquisas bibliográficas. Os resultados obtidos demonstram que todas as famílias participantes da pesquisa têm consciência das consequências negativas do descarte incorreto dos resíduos ao meio ambiente e a saúde, porém, existe uma contradição no que ocorre na prática. A administração pública e a população rural devem procurar unir esforços para diminuir os impactos causados pelo descarte incorreto dos resíduos.

RESUMO: A Leishmaniose Tegumentar Americana (LTA) é uma doença de caráter infeccioso e não contagiosa que afeta tanto o homem como diversas espécies de animais silvestres e domésticos, apresentando as formas clínicas cutânea, mucocutânea e cutânea difusa. O presente trabalho objetivou avaliar as características epidemiológicas da leishmaniose tegumentar americana em Alagoas, no período de 2010 a 2018. Para tanto, foi realizado um estudo quantitativo, de cunho descritivo e retrospectivo, a respeito do perfil epidemiológico da doença, utilizando como fonte dos dados, o Sistema Nacional de Agravos de Notificação (SINAN) e artigos científicos sobre o tema. As variáveis verificadas foram: mesorregião, ano diagnóstico, forma clínica, gênero, raça/cor, faixa etária, zona de residência e evolução dos casos. No período analisado, ocorreram 498 notificações, sendo 83,13% procedentes do leste alagoano. A forma clínica cutânea foi a de maior prevalência (93,1%), e o gênero masculino e os pardos, apresentaram respectivamente 66% e 63,6%.  A faixa etária de 20-39 anos foi a mais atingida (27,1%). A doença continua apresentando uma distribuição importante na zona rural, com 80,3% dos casos.  A letalidade permanece baixa, com 78,5% dos pacientes evoluindo para a cura. A partir dos dados encontrados, foi verificado que o perfil epidemiológico da LTA em Alagoas continua muito semelhante à maioria dos estudos sobre o tema. Nos últimos anos, apesar das reduções sucessivas no número de casos notificados, a doença continua endêmica no estado, principalmente em razão de fatores de risco, como a fragilidade socioeconômica e pessoas vulneráveis morando na área rural em moradias inadequadas. Desse modo, é necessário reforçar as medidas de controle e preventivas para evitar um aumento do número de casos na região.

ABSTRACT: The objective of the present study was to evaluate the effects of different culture media on the in vitro germination and initial development of Cattleya nobilior, and to acclimatize this species using soybean straw as a substrate component, aiming the production of plants at large scale to reintroduce it in natural environments. Anatomical characteristics associated with development during acclimatization are also depicted. The influence of Murashige and Skoog, Knudson, and Vacin and Went culture media on the in vitro germination and protocorm development were assessed. Acclimatization was accomplished using different proportions of soybean straw (SS) and Bioplant (BP) as substrates. Anatomical studies were conducted on the leaves of plants during acclimatization. KC was the most suitable culture medium for both germination and initial development of C. nobilior. Regarding acclimatization, it is recommended that a substrate composed of 60% SR and 40% BP be initially used. Upon transfer to shade-house conditions, plants should be grown in a mix of 40% SR: and 60% BP. The leaf anatomical characteristics observed are typical of epiphytic orchids adapted to water-poor environments, which indicates that SR did not negatively affect the development of the species. The in vitro propagation of C. nobilior as described herein is efficient for its multiplication for commercial and conservation purposes and SS can be used as an alternative component of the substrate for its acclimatization.

RESUMO: Dentre as infecções respiratórias, a Síndrome Gripal (SG) é caracterizada em pacientes com febre de início súbito, com tosse, dor de garganta, e com sintomas como mialgia, artralgia ou cefaleia. O objetivo do presente estudo é analisar os casos de SG notificados e resultados obtidos por um Laboratório de Referência em Saúde Pública. Trata-se de um estudo de tipo transversal, desenvolvido a partir das fichas de notificação e resultados notificados de SG obtidos através do Núcleo de Vigilância do LACEN-GO. Utilizou-se o software Epi info 3.5.4 para transcrição dos resultados, análise das variáveis contidas na ficha de notificação e teste de Qui-quadrado (x2). Foram analisadas 645 fichas de notificação de SG e seus respectivos resultados notificados. A maioria dos casos possuíam entre 21-30 anos, para a identificação da etiologia viral utilizou a RT-PCR. Quanto ao perfil epidemiológico a maioria dos casos eram do sexo masculino, não gestantes, escolaridade maior que 8 anos, não vacinados. Os principais sinais e sintomas foram febre, tosse e dor de garganta. As principais comorbidades foram doença cardiovascular crônica e diabetes mellitus. O principal agente etiológico viral diagnosticado foi o vírus Influenza A/H3N2. A vigilância epidemiológica da Influenza através dos casos notificados pelas unidades sentinelas de SG, é uma importante ferramenta para a saúde pública e se tornou o fator fundamental para a prevenção, contenção, vigilância e manejo terapêutico de pacientes.

RESUMO: O presente artigo tem como objetivo analisar a viabilidade econômica da implantação de uma trilha ecoturística interpretativa no município de Murici (AL). Para elaboração da trilha foi utilizado o método de Indicadores de Atratividade de Pontos Interpretativos (IAPI), sendo aplicado um questionário estruturado junto aos moradores da comunidade, em 2017. Para a análise da viabilidade foram levantados os principais custos e receitas para a implantação e o funcionamento da trilha. Posteriormente, foi realizada a análise do período de Payback e do Valor Presente Líquido (VPL), a partir dos fluxos de caixa projetados. Os resultados revelaram que os moradores da comunidade de Porto Velho são favoráveis a implantação da trilha interpretativa e se mostraram dispostos a assumirem a gestão. A análise financeira evidenciou a viabilidade do investimento. Desta forma, concluiu-se que há potencial ecoturístico na região e os retornos a serem obtidos no investimento tornam viável a implantação da trilha interpretativa na localidade.

Published: June 2021

RESUMO: O trabalho teve como objetivo avaliar o potencial antioxidante do extrato de Curcuma longa L. na estabilidade oxidativa do óleo de soja. Para isso, os tratamentos Controle (óleo de soja), TBHQ100 (óleo de soja com 100 mg de TBHQ/kg), Extrato100 (óleo de soja com 100 mg de β-caroteno de extrato/kg) e TBHQ50+Extrato50 (óleo de soja com 50 mg de TBHQ/kg de óleo de soja + 50 mg de β-caroteno de extrato/kg) foram submetidos ao teste acelerado em estufa (60 ºC/20 dias). O extrato apresentou 51,17% de atividade antioxidante pelo método DPPH• e 98,74 μM Trolox.g-1 pelo FRAP, além de 457,9 μg β-caroteno.g-1. Embora, inicialmente, todos os tratamentos tenham apresentado baixos valores de índice de peróxidos (0,55-0,65 meq.kg-1), em 20 dias, o Controle mostrou maior degradação oxidativa, 46,15 meq.kg-1. O TBHQ100 e TBHQ50+Extrato50 apresentaram os menores valores de p-anisidina. Apesar do TBHQ100 ter apresentado maior estabilidade oxidativa (8,25 h), o TBHQ50+Extrato50 (6,41 h) mostrou maior estabilidade que o Controle (3,86 h). Todos os tratamentos apresentaram elevadas concentrações do isômero γ-tocoferol. O antioxidante sintético provou ser mais eficiente na prevenção da reação de oxidação do que o antioxidante natural, visto que possui elevado grau de pureza. Entretanto, o TBHQ50+Extrato50 apresentou resultados satisfatórios, sendo o segundo melhor tratamento capaz de reduzir as alterações do óleo de soja, possibilitando a aplicação para a redução da concentração do antioxidante sintético.
