Published: August 2021

Wood materials have been used in many products such as furniture, stairs, windows, and doors for centuries. There are differences in methods used to adapt wood to ambient conditions. Impregnation is a widely used method of wood preservation. In terms of efficiency, it is critical to optimize the parameters for impregnation. Data mining techniques reduce most of the cost and operational challenges with accurate prediction in the wood industry. In this study, three data-mining algorithms were applied to predict bending strength in impregnated wood materials (Pinus sylvestris L. and Millettia laurentii). Models were created from real experimental data to examine the relationship between bending strength, diffusion time, vacuum duration, and wood type, based on decision trees (DT), random forest (RF), and Gaussian process (GP) algorithms. The highest bending strength was achieved with wenge (Millettia laurentii) wood in 10 bar vacuum and the diffusion condition during 25 min. The results showed that all algorithms are suitable for predicting bending strength. The goodness of fit for the testing phase was determined as 0.994, 0.986, and 0.989 in the DT, RF, and GP algorithms, respectively. Moreover, the importance of attributes was determined in the algorithms.

Published: August 2021

Sous-vide treatment is a modern minimal processing cooking technique that uses a single-step temperature of 55–70 °C and longer time. The quality attributes of meat might be improved by including cooking steps at below 50 °C temperatures in the sous-vide treatment. The aim of this study was to investigate the effects of the double-step sous-vide treatments on the quality attributes of the chicken breast and comparing with the traditional single-step sous-vide treatments. The single-step sous-vide treatments were performed at 60 °C. In the double-step sous-vide treatments the first step temperature was 45 °C and the end temperature was 60 °C. Double-step sous-vide treated chicken breasts obtained higher tenderness, moisture content and lower weight loss compared to the single-step sous-vide treated chicken breasts. Double-step sous-vide treatment provided an attractive cooking method to produce high quality chicken breast, however, challenge tests for specific pathogens would be useful for the assessment of the microbiological quality for different treatment combinations.

Published: August 2021

This article aims to reveal the discourse on the resistance of two Javanese ulama who were victims of the Dutch colonial politics of exile in the 19th Century. This study uses several letter manuscripts written by Kiai Ahmad Arrifai Kalisalak and Kiai Hasan Maolani Kuningan from their exile as primary sources. The letters addressed to his family and followers in Java were written in Javanese with the Pegon script. Through historical studies and discourse analysis, this study finds that the Dutch colonial politics of exile was not able to dampen the resistance of the ulama. The writing of letters from exile by Kiai Ahmad Arrifai Kalisalak and Kiai Hasan Maolani was intended to compete with the colonial powers, producing heretical discourses and disturbing public order as a pretext to banish them. Thus, this article concludes that the two ulama did from their exile was a new mode of resistance against colonialism.
Uma moral “corporal” generificada nos manuais escolares franceses de moral e de higiene (1880-1974)
Authors: Gleyse Jacques , Lima Neto Avelino Aldo de
Published: August 2021

RESUMO O estudo dos manuais escolares franceses de Moral e Higiene do final do século XIX ao segundo terço do século XX permite descrever os preconceitos e estereótipos de gênero ligados aos diversos temas presentes nessas obras. As poucas rupturas nelas identificadas estão mais associadas a mudanças nos procedimentos didáticos do que à questão do gênero. Nesse domínio, o tratamento é bastante diferente conforme o sexo. Igualmente distintas são as temáticas encontradas quando se trata do autocuidado, de prescrições e de proibições corporais. Nas recomendações às meninas, são frequentes os assuntos da paciência, do asseio, da temperança, da coragem moral, da ordem, da sobriedade na comida e bebida; nos conselhos aos meninos, surgem as discussões sobre a coragem, a embriaguez, o alcoolismo, as proezas físicas, o suicídio, a mutilação, o trabalho e a preguiça. Os acontecimentos marcantes quanto à situação da mulher no século XX não parecem ter impactado os manuais escolares, tanto em termos dos textos escolhidos como da iconografia, com pouquíssimas exceções.

Published: August 2021

ABSTRACT The objective of the present study was to investigate the different plasma metabolites between anestrus and estrus postpartum dairy cows and to provide a theoretical basis for prevention of anestrus in dairy farm cows. In the experiment, one hundred and sixty-seven Holstein dairy cows were selected with similar age and parity. According to the concentration of β-hydroxybutyric acid, non-esterified fatty acids and glucose in plasma during 14 to 21 days in milk, all dairy cows were determined as having a status of energy balance. According to the results of clinical symptom, rectal and B ultrasound examination at 60 to 90 days postpartum, these cows were divided into twenty estrus and twenty-four anestrus group, other dairy cows were removed. 1H nuclear magnetic resonance technology was utilized to detect the plasma metabolites changes and screen different plasma metabolites between anestrus and estrus cows. Ten different metabolites including alanine, glutamic acid, asparagine, creatine, choline, phosphocholine, glycerophosphocholine, low-density lipoprotein, and very-low-density lipoprotein were significantly decreased in anestrous cows compared with estrous cows. Metabolic pathway analyses indicated that differential metabolites were primarily involved in amino acid and glycerophospholipid metabolism. These metabolites and their enrichment pathways indicate that reduced steroid hormone synthesis precursors result in lower levels of estradiol and progesterone and cause anestrus in negative energy balance. These data provide a better understanding of the changes that may affect estrus of postpartum dairy cows at NEB status and lay the ground for further research.

Authors: Jahedi A. , Zarei A.
Published: August 2021

ABSTRACT The present study was conducted to investigate the effect of electrical and thermal systems optimization on energy consumption in broiler farms. Experiments were conducted in 4 different climates (cold, hot, dry, and temperate) with four treatments (4 broiler farms in each region) and 5 iterations (5 rearing periods per farm) on the Ross 308 strain of broiler chicken in a completely randomized basic design. The results showed that the solutions applied in cold and dry climates had a significant effect on reducing energy consumption (P<0.05). In the hot climate, although the reduction in energy consumption was observed after the application of the solutions, the difference was not statistically significant (P>0.05). Also, the application of solutions in temperate climates created a significant difference in the specific amount of thermal energy consumption per kilo of meat and total energy (P<0.05). Overall, the results of the present experiment showed that optimizing the electrical and thermal systems of broiler houses could reduce energy consumption in all climates.

ABSTRACT The objective of this study was to evaluate follicular growth and ovulatory rates in mares treated with an intravaginal progesterone device (P4) during the 10-day period, associated with the use of estradiol benzoate (EB). The results were compared during the transition period (ET) in the spring and the breeding season in the summer (ER). The variables were submitted to ANOVA (Tukey's test), considering P<0.05. No ovulation occurred during the permanence of the P4 implant in both experimental periods. The ovulatory rate in the ER was 100% (n = 8) and in the ET 62.5% (n = 5; P = 0.0547). Significant differences were observed (<0.001), in both periods, comparing follicular growth rates during the permanence of P4 device (ER: 1.33 ± 0.89mm/d; ET: 1.00 ± 0.81mm/d) to the period without P4 (ER: 3.63 ± 1.33 mm/d; ET: 3.31 ± 1.66 mm/d). The present study demonstrated applicability and efficiency of a hormonal protocol using P4 intravaginal device and EB for follicular control in mares, both during ET and ER.

ABSTRACT The aim of this research was to determine the influence of lactation number and parity on milk yield of Saanen goat’s breed. It has been concluded that milk yield was higher for goats that had given birth to twins and three kids than for goats that had given birth to a single kid (P<0.05). The longevity has a great positive impact on production, given that goats in the fifth lactation produced more milk than goats in first or second lactation (P<0.05), while goats in the sixth lactation still produced more milk than goats in first lactation (P<0.05). During the period from 2014- 2019, the research was conducted on a farm of multiparous Saanen goats in Vojvodina (northern part of Serbia). In the observed period, the farm had between 350 and 400 goats per milking, and the research included a total of 1,628 concluded lactations, within which the first lactations were the most 484, then the second 381. According to the number of lactations, goats were grouped into classes from one to seven and from one to three for parity. By comparing each individual lactation, it was determined that in first lactation goats produced significantly lower milk than goats in the rest lactations(P<0.05), except the seventh. Research has shown that lactation number has a significant influence on milk yield (P=0.00). Increasing the fertility of goats significantly affects the production capacity of dairy goats, since does with a larger number of kids in the litter had a significantly higher milk production (P<0.05). Due to the larger number of kids in the litter, milk production also increases. Likewise, it is assumed that the increase in milk yield of goats with two and three kids is a consequence of a larger placenta, i.e. stronger lactogenic activity during pregnancy.

Published: August 2021

ABSTRACT This study aimed to evaluate the influence of commercial thermal treatment on Eucalyptus grandis considering its physical, chemical, and mechanical properties. The wood samples were heat-treated in an autoclave with saturated steam and pressure application at four different temperatures: 155, 165, 175, and 185 ºC. The physical, chemical, and mechanical properties were altered due to the heat treatment. The extractives content varied between 6.06% and 28.75%; lignin between 28.93% and 37.96%; holocellulose between 65.01% and 38.12%. The mechanical properties reduced significantly with the increase of the heat treatment temperature. Through the set of data obtained, it was possible to generate significant and high precision regression models capable of estimating such properties for heat treatment temperatures not studied experimentally, enabling the determination of the most suitable temperature of heat treatment to achieve a certain property value of the treated wood.

Published: August 2021

Resumo: O objetivo deste artigo é aplicar a Multi Level Perspective (MLP) a um caso de transição para a sustentabilidade da agricultura que ocorre a partir do desenvolvimento de uma inovação agroecológica. À perspectiva temporal e multinível dada pela MLP, conjugamos o conceito de Agricultural Knowledge and Innovation Systems (AKIS), com a intenção de conciliar uma dimensão territorial para a análise. O cenário empírico é a região vitivinícola do Douro, em Portugal, na qual se disseminou uma inovação denominada Infraestrutura Ecológica (IE). Metodologicamente, fizemos entrevistas pessoais estruturadas, realizadas com agricultores ou gestores agrícolas, representantes de explorações comerciais de uva e vinho. Constatamos que há um princípio de transição liderado por agricultores corporativos que comercializam no mercado global. Este princípio de transição está alicerçado na mobilização de um AKIS territorial que permitiu o desenvolvimento do arcabouço cognitivo e técnico que estruturou o setor para sua articulação às demandas de mercado. Entretanto, este AKIS não é igualmente mobilizado pelos diferentes agricultores, o que se manifesta em distintas respostas de adoção da inovação. O caso explicita como as pressões de paisagem sociotécnica, representada pelo mercado, podem criar diferentes respostas no regime local.

Abstract – The objective of this systematic review was to identify the association between overweight/obesity and level of physical activity in Brazilian children and adolescents in the school setting. For search strategy, the main reference databases (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC) were used. Baseline searches resulted in 3,265 potentially relevant titles (2,775 titles after removal of duplicate studies); 21 studies met all inclusion criteria and were included for analysis. Studies were carried out from 2007 to 2019; 47.6% of them were conducted in Southern Brazil, and only one study had nationwide approach. Prevalence from 5.4% to 21% was identified for overweight, 3.5% to 16.9% for obesity and 11.8% to 40.1% for overweight + obesity. According to results, 64.3% of overweight, 69.8% of obese and 37.7% of young overweight people were considered insufficiently active. The non-standardization of instruments to assess levels of physical activity and the lack of information regarding other Brazilian regions were classified as important limitations. The results reinforce the increase in the prevalence of overweight in Brazilian children and adolescents, and the high prevalence of physical inactivity among them. For every ten overweight children/adolescents, six are reported to be insufficiently active.

Published: August 2021

Abstract One of the actual areas of processing the aquatic biological resources is the production of chilled fish semi-finished products, the most prepared for heat treatment. Such products have a very limited shelf life, because fish raw materials have high enzymatic activity. This research work aimed to improve the technology of chilled fish semi-finished products from Japanese mackerel with an extended shelf life. To achieve this goal, Japanese mackerel was injected with multicomponent salting media, containing food additives that slow down microbial contamination, have a bacteriostatic effect and assist in improving the organoleptic characteristics of the finished product. New receptions of salting multicomponent compositions provide faster salting and ripening of raw materials compared to the control sample. Salt concentration in fish, amine nitrogen and peroxide value were determined by titration methods. The total number of mesophilic aerobic and facultative anaerobic microorganisms (КMAFAnM) in fish semi-finished products was determined by identifying the number of grown colonies of microorganisms on nutrient media from agar. The treatment of Japanese mackerel with developed salting media, including moisture-retaining components, organic acids and flavoring additives with anti-bactericidal properties, improves the organoleptic characteristics of the finished product, promotes more salting and maturation of fish, as well as reducing the number of microorganisms (KMAFAnM). The increase in amine nitrogen content ranged from 1.4 g/kg (at the beginning of the salting) to 1.55 g/kg in the control and up to 3.05 g/kg in the test samples by the end of the salting. Salt concentration in Japanese mackerel treated with control salting media amounted to 1.19%, new developed salting media - from 2.84% to 3.17%. The total abundance of microorganisms in Japanese mackerel was 2.0 x 102 CFU/g, after salting it decreased to 0.1 to 3.0 x 101 CFU/g depending on the formulation of media for salting. According to the research results, the rational duration of the salting of Japanese mackerel, with new media for salting was 4 to 5 h at a temperature of 6 °С to 8 °С. Along with the salting media developed by us, the use of modern packaging materials in the technology provided chilled culinary semi – finished products from Japanese mackerel with longer shelf life of up to 20 days at a temperature of 0 °С to 5 °C, and humidity 95% to 98%.

Published: August 2021

ABSTRACT The growing need for solving the problem of food waste for tackling the survival of the planet and humankind is encouraging researchers to seek sustainable operations that alter the conventional methods that are currently in use in the food industry. Lean thinking has been used in this study to propose sustainable operations that incorporate social, economic, and environmental aspects and to handle the multidisciplinary and complex nature of reducing food waste. The value stream mapping methodology has been employed to explain food waste and generate drivers and to observe the end-to-end system flow. Since most of the waste is observed in upstream operations in emerging economies, one of the biggest meat-processing companies in Turkey is studied for illustrating the proposed methodology. As a result of the model, lean and sustainable food operations are suggested considering social, economic and environmental aspects.

Published: August 2021

RESUMO O desperdício de alimentos pode ser observado em toda a indústria alimentícia, refletindo em efeitos negativos nas esferas social, ambiental e econômica. Este estudo objetiva contribuir para a identificação dos fatores preditores desse comportamento, especificamente, relacionando a propensão a procrastinar e as variáveis controle de alimentos e esforço percebido como mediadoras do comportamento em relação ao desperdício de alimentos. Para tanto, foi realizada uma coleta por meio de survey on-line, com uma amostra final de 279 respondentes, e as hipóteses foram analisadas com a modelagem de equações estruturais (MEE). Como principais resultados, destaca-se que a procrastinação não se mostrou significativa para explicar o comportamento de desperdício de alimentos, e o controle desses produtos reduz a percepção de esforço. Além disso, elucida-se que um maior controle realizado de maneira intuitiva é contraproducente. Como uma das principais contribuições gerenciais deste estudo, ressalta-se a urgência por difusão de cartilhas e treinamentos com o objetivo de disseminar técnicas de controle de alimentos e acessibilidade às informações sobre o período de durabilidade dos produtos alimentícios.

RESUMO O artigo problematiza o ideário e a prática contemporâneos do Projeto Urbano, enfocando a Operação Urbana Consorciada (OUC) Porto Maravilha, Rio de Janeiro. A evolução dessa intervenção de 2009 até o presente permite argumentar que os descompassos entre planos e projetos que configuram a política urbana carioca impediram o desenvolvimento de uma escala local para a área de interesse dessa OUC, e seu Projeto Urbano. Identificando eventos, processos e resultados ambientais, evidencia-se a condição excludente e desigualdades socioterritoriais na área, obstando a escala local.
Lugares do Catolicismo Negro na São Paulo do século XIX
Authors: Santos Fabrício Forganes
Published: August 2021

resumo No século XIX, auge da presença dos negros na cidade de São Paulo, quatro Irmandades de Homens Pretos se inseriam no plano urbano, demarcando os lugares onde a população excluída poderia estabelecer redes de sociabilidade, preservando ainda referenciais africanos. O fluxo de devotos negros nessas e nas outras igrejas permitiria o estabelecimento de territórios do Catolicismo Negro em São Paulo, considerados como gêneses da presença urbana negra nesta cidade. Para além da apresentação desses marcos arquitetônicos e reconhecimento desses lugares da cena religiosa dos Oitocentos, o exercício de identificá-los a partir dos documentos primários tem como fim último revelar traços de uma história urbana ainda silenciada.

Published: August 2021

Resumo Os países europeus estão experimentando uma redução nas taxas de imunização em um momento de expansão dos movimentos antivacinas. Nesse contexto, a mídia pode desempenhar um papel crucial, tanto na difusão de crenças, quanto na circulação de informações confiáveis sobre o tema. Este estudo analisou a cobertura jornalística sobre vacinas na imprensa portuguesa. Foi realizada uma análise de conteúdo em uma amostra de 300 artigos publicados no Diário de Notícias e no Jornal de Notícias de 2012 a 2017. Houve uma predominância de textos relacionados às vacinas contra a gripe, sarampo e meningite. Os temas mais frequentes foram: estoque de vacinas, pesquisa sobre vacinas, cobertura vacinal e campanha de vacinação. A maioria dos artigos apresentou um tom positivo e neutro em relação à imunização. Os jornais colocaram as vacinas em sua agenda midiática, possivelmente influenciados pelas políticas de saúde pública presentes em Portugal. Tais achados reforçam a percepção que a mídia pode ser um instrumento na divulgação de informação confiável sobre o tema. Apesar de o tom negativo ser pouco presente, títulos de notícias com ênfase nas reações adversas das vacinas poderiam contribuir para despertar ou aumentar a desconfiança nos seus benefícios.

abstract: Current practices in structural engineering demand ever-increasing knowledge and expertise concerning stability of structures from professionals in this field. This paper implements standardized procedures for geometrically nonlinear analysis of steel and reinforced concrete structures, with the objective of comparing methodologies with one another and with a geometrically exact finite element analysis performed with Ansys 14.0. The following methods are presented in this research: Load Amplification Method, from NBR 8800:2008; the γ z coefficient method, from NBR 6118:2014; the P-Delta iterative method and the α c r coefficient method, prescribed in EN 1993-1-1:2005. A bibliographic review focused on standardized approximate methods and models for consideration of material and geometric nonlinearities is presented. Numerical examples are included, from which information is gathered to ensure a valid comparison between methodologies. In summary, the presented methods show a good correlation of results when applied within their respective recommended applicability limits, of which, Eurocode 3 seems to present the major applicability range. The treated approximate methods show to be more suitable for regular framed structures subjected to regular load distributions.

Abstract Stomoxys calcitrans is a hematophagous dipteran. Several agents are used in biological control, including entomopathogenic nematodes (EPNs). Bioassay I involved an evaluation of the effect of Heterorhabditis bacteriophora HP88 and Heterorhabditis baujardi LPP7 on S. calcitrans larvae in different periods of exposure. Groups of 10 larvae were placed in Petri dishes and 200 EPNs/larva were added, which were divided into groups according to the exposure times of 2, 4, 6, 12, 24 and 48 hours. The purpose of Bioassay II was to evaluate the efficacy of the EPNs in infecting S. calcitrans larvae when they were isolated from stable fly larvae in Bioassay I. Groups of 10 larvae were placed in Petri dishes and 200 EPNs/larva were added. In bioassay I, H. bacteriophora caused mortality rates of 51.7, 83.3 and 91.7% in 12, 24 and 48 hours, respectively, while H. baujardi caused mortality rates of 9.3 (12h), 35 (24h) and 35% (48h). In Bioassay II, H. bacteriophora and H. baujardi resulted in mortality rates of 35% and 25%, respectively. It was concluded that the longest exposure times presented the highest larval mortality and that EPNs isolated from S. calcitrans are not efficient in controlling the larvae fly.

Published: August 2021

Este estudo foi motivado por uma inquietação diante dos recorrentes relatos de docentes que atuam no ensino médio e superior quanto à deficiência dos estudantes no que diz respeito à linguagem natural escrita na norma padrão e à organização de soluções para problemas com o uso de estratégias associadas ao pensamento computacional (PC).  Diante desse contexto desafiador, realizou-se uma revisão integrativa de literatura com a intenção de analisar as sequências didáticas de trabalhos que envolvem a construção de narrativas multimodais no ensino fundamental, as quais trabalham simultaneamente o desenvolvimento da linguagem escrita e do pensamento computacional, sendo também entrevistados professores de sala de aula com o propósito de ouvir suas vivências a respeito do tema investigado. Como resultado da revisão integrativa de literatura e das entrevistas, propôs-se uma sequência didática que inclui a remidiação como o eixo em torno do qual a linguagem natural escrita na norma padrão se articula com a autoria de narrativas digitais para promover o fortalecimento da linguagem natural escrita na norma padrão, o uso consciente de variações linguísticas e o desenvolvimento do pensamento computacional. As entrevistas exploratórias com professores de sala de aula contaram com a participação de somente quatro voluntários, o que constitui uma limitação deste estudo. Por fim, para estudos futuros, considera-se importante a aplicação da sequência didática proposta em contexto de sala de aula para sua validação e aperfeiçoamento.
Identidades transnacionais e transculturais. Pós-colonialidade, lusofonias e interculturalidade. O caso do Museu Virtual da Lusofonia
Authors: DE SOUSA Vítor
Published: August 2021

A identidade do “eu” está sujeita à presença de um “outro”, não de forma a apagar os seus próprios valores, mas a permitir a expansão das suas visões de mundo. Através do conceito de transculturalidade (Welsch, 1999), sustenta-se a ideia de que as culturas estão em processo constante de interação e de mistura. Este artigo, dedicado à problemática das identidades transnacionais e transculturais, deixa para trás o luso-tropicalismo do sociólogo brasileiro Gilberto Freyre (1953; 1961) e o conceito ancestral e unívoco de cultura, que pontuou o discurso da ditadura portuguesa do Estado Novo, voltando-se para a diversidade das lusofonias. Neste quadro, o Museu Virtual da Lusofonia pode ter uma importância fundamental enquanto possibilidade intercultural.
Plataformização, tecnopopulismo e desintermediação das fontes em ataques ao jornalismo no Instagram
Authors: PAGOTO Lia Gabriela , LONGHI Raquel Ritter ,   Universidade Federal de Santa Catarina
Published: August 2021

Este artigo discute como o processo de plataformização pode contribuir para dilatar a crise de deslegitimação do Jornalismo. Associando a lógica de funcionamento das plataformas de redes sociais a uma retórica de descredibilização da imprensa, políticos como Jair Bolsonaro passam a utilizar as redes sociais para enunciar sua “verdade” diretamente ao seu público. Observamos o impacto dessa práxis através da análise de comentários em notícias de dois veículos brasileiros no Instagram: CNN Brasil e Folha de S. Paulo, numa amostra que compreende 33.651 intervenções. O resultado assinala uma correlação discursiva entre a gramática dos usuários e a de Bolsonaro e mostra um aumento de ataquesà imprensa em notícias relacionadas ao Presidente, configurando, assim, o poder do tecnopopulismo nas plataformas.
Support System for Semiautomatic Quantification of Pulmonary Fibrosis in CT Images
Authors:   , Rodríguez-Obregón D. E.
Published: August 2021

A method to estimate the pulmonary fibrosis in computed tomography (CT) imaging is presented. A semi-automatic segmentation algorithm based on the Chan-Vese method was used. The proposed method shows a similar fibrosis region with respect to clinical expert. However, the results need to be validated in a bigger data base. The proposed method approximates a fibrosis percentage that allows to achieve this procedure easily in order to support its implementation in the clinical practice minimizing the clinical expert subjectivity and generating a quantitativeestimation of fibrosis region.
Characterizing the hippocampal theta’s response to carbachol; using a complete septo-hippocampal preparation
Authors:   , García-Méndez K. M.
Published: August 2021

The present study describes the pharmacological analysis of the effects of carbachol, a cholinergic agonist, on hippocampal theta activity. Knowing that this activity is critically related to cognitive function and altered in patients with neurodegeneration, pharmacological efforts aiming to directly modulate hippocampal theta activity becomes of central importance. In a recently developed complete septo-hippocampal preparation, carbachol elicited significant theta power enhancement with 1 μM. Concentrations under 1 μM and over 2 μM carbachol caused significant reduction in the power of hippocampal theta activity. Carbachol effects were completely blocked with the cholinergic antagonist scopolamine. At the experimental level, it is the first time the direct action of a cholinergic agonist is evaluated in the septo-hippocampal pathway completely isolated. However, carbachol as a cholinergic agonist is a drug with a certain level of nonspecific response. That is why to correct this experimental limitation, we used scopolamine (cholinergic antagonist) which allowed us to corroborate the effects on the cholinergic pathway. In summary, electrophysiological assays demonstrated an effective concentration range of carbachol specifically modulating hippocampal theta activity.

Authors:   , Quihu- Cota L.
Published: August 2021

Chitosan (CH) has hemostatic properties and accelerated healing ability to stimulate the host immune system against viral and bacterial infections. It is also biodegradable, nontoxic, antimicrobial, biocompatible, and capable of forming membranes and to carry and to release bioactive compounds. These properties of CH can be useful to carry some volatile essential oils having bioactive compounds (antioxidants and antimicrobials) with potential application in human health as those as rosemary (RMO) [Rosmarinus officinalis] and tea tree (TTO) [Melaleuca alternifolia]. These essential oils were incorporated into the chitosan by the casting method in this study. The physical properties (solubility, PVA, transparency and blocking ultraviolet light) of these membranes with TTO and RMO (0.25, 0.50 and 1.00% v/v), antioxidant capacity and protection human erythrocyte were evaluated. TTO and RMO reduced solubility (28-58%) and PVA (between 28-58%) of CH membranes. All membranes were yellow, slightly opaque and they were able to block the ultraviolet light. Membranes also showed relatively low antioxidant capacity by the radical ABTS (≈ 6 at 9%), but it was accompanied by an excellent protective effect on the human erythrocyte (> 63%).

Authors:   , Alvarado-Noguez1 M. L.
Published: August 2021

Photoacoustic Spectroscopy (PAS) stand outs among Photothermal techniques due to its versatility for the characterization of different types of materials, including biological samples. In this study, were compared and analyzed by PAS, the differences between the optical absorption spectra of blood of male Fisher rats, in three cases, control (healthy rats), liver damage and liver damage treated with Curcuma longa. The experimental results show differences in the optical absorption spectra of each analysed case, therefore PAS would be proposed as a non conventional complementary technique, to study the effect of Curcuma longa in induced liver damage for an animal model.

Clinical decision support system for decision making in mammary glands thermography
Authors:   , Bastida M. B.
Published: August 2021

A decision tree based system with heuristic weight factors oriented to diagnosis by thermography was developed. The proposed clinical decision support system (CDSS) includes binary decision trees for statistical classification of some diseases of the mammary gland. These include weight constant factors found by the correlation of the variables involved in the development of breast disorders according to the statistical attachment of the thermal features, as well as complementary clinical information (medical history, physical parameters, genetic load and habits, among others), regarding its diagnostic incidence. The certainty of the system for inflammatory disorders is 96%, for fibrocystic mastopathy is 78 %, for fat necrosis is 62% and for breast cancer is 86%. The 14% error is associated to microcalcifications that with the reported thermographic technique it is not possible to differentiate. Thus, it is possible to catalog the risk of a patient having a condition according to the results obtained after conducting a thermal test. Then, with the CDSS the possibility of applying early detection tests in the population suffering from contraindications to perform the others is improved, in addition it allows a comprehensive diagnosis for other patients

URBAN PLANNING WITH THE GOALS OF SUSTAINABLE DEVELOPMENT
Authors: Gromilina Elvira Alekseevna
Published: August 2021

The problem of urban planning in the context of globalization and the intensification of urban growth is considered in the context of sustainable development. Under UN-Habitat regulations, urban development must be in line with five principles: compactness, high density, mixed use, variety, limited land-use specialization. Compact urban development is a model for sustainable urban development, based on the synergy of three main dimensions: social, economic and environmental. In contrast to the approach to territorial zoning, the compact city model pays attention not only to the development of mixed land use, but also to social needs in places of employment, leisure, recreation, as well as the need for economic resources. In order to identify strategies for designing a sustainable architectural and planning structure, theoretical approaches to the practice of urban planning are investigated. Implementation of the provisions of UN-Habitat is aimed at reducing energy consumption and harmful emissions, preserving biodiversity, reducing the cost of infrastructure and increasing labor productivity, which helps to achieve a balance of social, economic and environmental goals of sustainable development.
