Published: July 2020

Resumo Objetivo: Comparar os efeitos do Pilates vs. vibração de corpo inteiro (VCI) e nenhuma intervenção sobre o equilíbrio postural e medo de quedas em mulheres na pós-menopausa. Métodos: Ensaio clínico Mono-cego, com 51 participantes randomizadas em três grupos (Pilates, VCI, ou Controle). Avaliações foram realizadas para o equilíbrio postural estático por intermédio da plataforma de força, equilíbrio postural dinâmico pelo teste Timed Up & Go e medo de quedas pela Falls Efficacy Scale-International (FES-I). Pilates e VCI foram administrados três vezes na semana, por seis meses. Resultados: Após a intervenção, nenhuma diferença (p> 0.05) foi observada para o equilíbrio postural estático, contudo, para a maior parte das variáveis, Pilates e VCI demonstraram um grande tamanho de efeito (d> 0.80) quando comparados ao grupo controle. Para o equilíbrio postural dinâmico, Pilates e VCI promoveram uma melhora significativa (p= 0.032) comparados ao grupo controle. Para o medo de quedas não houve diferença entre os grupos (p= 0.055) pós-intervenção. Conclusão: Tendo em vista a representatividade clínica evidenciada pelas medidas de tamanho de efeito, Pilates e VCI podem ser recomendados para melhora do equilíbrio postural estático e dinâmico em mulheres na pós-menopausa. Contudo, em relação ao medo de quedas, essas modalidades terapêuticas necessitam de melhor investigação.

Published: July 2020

Abstract The chemical profile of Dalbergia ecastaphyllum has been indicated as the botanical origin of Brazilian red propolis, an apicultural product with proven therapeutic properties. However, few studies have investigated this plant species. This study evaluated and compared microbiological quality, chemical composition, and antioxidant activity of stem and leaf samples of D. ecastaphyllum. The samples were collected in February 2015, in the southern region of the state of Bahia, Brazil. We performed the microbiological analyses, determined the contents of fatty acid, total phenol and flavonoid, and identified the chemical profile and antioxidant activit. Escherichia coli, Salmonella spp. and sulfite reducing clostridial spores were not detected in the samples. Acids of the family ω3 were recorded in the stems and ω6 in the leaves. The leaves presented better nutritional quality of the fraction, better antioxidant capacity in the tests by the DPPH method and β-carotene bleaching. There were 49 chemical compounds, of which 38 belonged to the class of flavonoids. The results indicate that stems and leaves of D. ecastaphyllum have biological properties. Leaves particularly are better for functional food formulation and as natural antioxidant.

Published: July 2020

Abstract Cissus erosa (Vitaceae), popularly known in Brazil as Cipó-fogo, is a medicinal plant used in the treatment of warts and external ulcers. The present study aimed to evaluate the activity of stems and leaves ethanol extracts of C. erosa against the Dengue and Zika virus by the MTT colorimetric method and to carry on the phytochemical characterization of active extracts by high performance liquid chromatography coupled to mass spectrometry (UPLC-MS). Only the leaves ethanol extract showed anti-Dengue virus activity EC50 18.2 µg/ml (SI > 27.5) and low cytotoxicity for LLCMK2 cells (CC50 > 500 mg/ml). Both extracts (stems and leaves) showed anti-Zika virus activity with EC50 of 45.8 mg/ml and 82.8 mg/ml, respectively. These extracts presented CC50 of 309.2 µg/ml (leaves) and 387.6 µg/ml (stems) to Vero cells. Analysis by CCD and HPLC-DAD detected the presence of triterpenes, steroids, flavonoids and tannins. UPLC-MS analyses of these extracts, allowed the identification of the majority of flavonoids present known as vitexin, isovitexin, orientin, isoorientin and two flavones derivatives, methoxyluteolin-6(8)-C-hexosyl and luteolin-7,4’-di-O-glycosylflavone. The results of the phytochemical studies here described suggest that flavonoids and terpenoids are the substances that contribute to the antiviral activity of the ethanol extracts within this species.

Abstract Thirty-six compounds were identified from aerial parts of Solidago chilensis cultivated at PAF/FIOCRUZ campus in Rio de Janeiro city (RJ) using solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) analysis. These compounds are mainly non-oxygenated mono and sesquiterpenes. Germacrene D is the major compound of two the essential oil analyzed samples (12 to 23%) and of two of the volatiles samples analyzed by SPME (central stems and dry inflorescences samples). Limonene is the major compound in the fresh inflorescences sample (about 21%). The bornil acetate is present in both volatile fractions (16%) and essential oils (7-8%). All the essential oils samples evaluated shown a great antinociceptive activity, considering the used dose of the samples (1 mg/kg) and the standard substance (50 mg/kg). Solidago chilensis is one of Brazil arnicas and it is a medicinal plant widely used by the brazilian population. Other plants of the genus Solidago are also used in traditional medicine in North America and Europe. This is the first report of SPME analysis from Solidago genus and of the antinociceptive effect from Solidago chilensis essential oil.

Published: July 2020

Abstract Maytenus s.l. is a genus of the Celastraceae family and many of its species are used in traditional medicine. Most of the substances responsible for the biological activities of plants come from their secondary metabolism, such as terpenoids and flavonoids, which have multiple functions in the plant and can occur in a similar way in plant groups. Chemophenetics analyzes the occurrence of these substances in a taxon and can infer evolutionary trends and contribute to the rational search for new drugs. Chemosystematic parameters were used to analyze the data obtained through a bibliographic survey. The species of Maytenus s.l. were separated into three groups: species with accepted names, synonymous species with the genus Monteverdia and synonymous species with the genus Gymnosporia. Due to their great occurrence and structural variety in Maytenus s.l., triterpenes were chosen as chemosystematic markers, with friedelanes and quinone methide triterpenes being the most expressive types. Studies have already demonstrated the analgesic potential of quinone methides and the antitumor potential of phenolic triterpenes and dimers of these units. Together, the three classes assist in the circumscription of Maytenus s.s. and Monteverdia, while lupanes can be used in the separation of these genera. Oleanans are representative of Gymnosporia.

Abstract The e-SUS is a software used to computerize the health work process in Brazil. Among the population registration data is the record about the use of medicinal plants in Primary Health Care (AB). Thus, our objective was to analyze the records of the e-SUS in a Basic Health Unit (UBS) in the Jequitinhonha Valley and conduct a survey with individuals from the same UBS, where they were asked about the use of medicinal plants. The hypothesis of the study is that although the registration is relevant, the software data underestimate the reality about medicinal plants use. In a survey with 77 users of an UBS randomly selected, 93.5% reported using medicinal plants, while in e-SUS reports only 0.8% of the individuals from the same UBS use medicinal plants. Therefore, the recorded data cannot yet be used to develop medicinal plant policies in the AB. Reliable record of medicinal plant use in e-SUS is still a challenge. It is important to make professionals aware of the benefits of correctly completing the forms for the development of public policies that include what is recommended by the National Medicinal Plants Policy in order to recognize, guide and value the use of medicinal plants.

Authors: Alba Thainara Marcotto , Pelegrin Carla Maria Garlet de , Sobottka Andréa Michel
Published: July 2020

Abstract The potential of a plant with medicinal and nutritional properties, Anredera cordifolia, is reviewed. Its common names include “Bertalha” and “folha gorda” and it is popularly used for wound healing and against fungal infections and other types of infection. Its pharmacological properties have been widely investigated and acknowledged, especially with regard to its antibacterial activity, which improves the healing of wounds infected by Staphylococcus aureus, and to its antifungal activity against Candida albicans. It is an unconventional food plant, with leaves and aerial tubers used as food prepared in varied ways. It is also considered an invasive plant in several countries and thus classified as a weed. Its characteristics of a Brazilian native plant, with proven medicinal properties and unconventional use as food, underlie our study on its ecology and botanical classification, as well as the pharmacological assays and screening of chemical constituents.

RESUMO Objetivo refletir acerca da atuação do enfermeiro obstétrico na atenção à mulher durante o processo parturitivo, sob a perspectiva teórica das Epistemologias do Sul. Método trata-se de estudo do tipo reflexivo, com base em uma revisão narrativa da literatura. Resultados após leitura e análise crítica dos documentos selecionados, e com base no referencial teórico das Epistemologias do Sul, emergiram dois eixos temáticos para reflexão, sendo eles: Descolonização do saber: atuação do enfermeiro obstétrico na reorientação do modelo de atenção à mulher durante o processo parturitivo; e O pensamento pós-abissal e a ecologia dos saberes versus práticas humanizadas de atenção ao parto e nascimento. Conclusão e implicações para a prática o enfermeiro obstétrico contribui para a valorização do conhecimento de grupos sociais poucos expressivos (minoritários), oprimidos ante à hegemonia de um modelo assistencial. Sua postura profissional busca a integração de distintos conhecimentos. A reflexão sobre a assistência da enfermagem obstétrica na perspectiva das Epistemologias do Sul poderá suscitar a discussão sobre as práticas obstétricas vigentes de modo a propulsionar a adoção de cuidados qualificados e humanizados na atenção à mulher durante o parto.

Published: July 2020

RESUMO Objetivo investigar a influência da timidez autorreferida na desvantagem vocal percebida, de acordo com a presença ou ausência de queixa vocal, em profissionais da voz. Métodos duzentos e oito profissionais da voz (média de 36 anos, desvio padrão: 11,5), entre cantores, atores, advogados, locutores, telejornalistas, palestrantes, professores e vendedores, com ou sem queixa vocal, responderam a um questionário on-line que continha uma ficha de identificação pessoal, o Índice de Desvantagem Vocal - IDV-10 e a Escala de Timidez Cheek & Buss. Resultados dos 208 profissionais da voz, 28% apresentaram desvantagem vocal, sendo que cerca de 60% destes eram tímidos; mais de 70% não apresentaram desvantagem vocal e destes, apenas 26% eram tímidos. Sendo assim, profissionais da voz tímidos falharam mais no IDV-10 do que os não tímidos. Entre os profissionais da voz que apresentaram desvantagem vocal, 66% tinham queixa vocal, enquanto 34% não apresentaram queixa. Dos sujeitos com desvantagem e queixa vocal, 54% eram tímidos e 46% não tímidos, sem diferença estatística entre estes dois grupos. Já entre os sujeitos com desvantagem, porém sem queixa vocal, 70% eram tímidos, e 30% não tímidos, havendo diferença entre eles. Conclusão a timidez pode ser um fator de confundimento para percepção de desvantagem vocal, o que indica que profissionais da voz podem falhar em um teste de autoavaliação vocal em decorrência da timidez e não de um distúrbio de voz, propriamente dito.

Published: July 2020

O artigo analisa a percepção de usuários da Atenção Básica de um município catarinense sobre eventuais mudanças imateriais tecidas no processo cotidiano de suas vidas após a chegada do Programa Mais Médicos. Trata-se de um estudo qualitativo, de abordagem humanística de análise da realidade, desenvolvido entre fevereiro e março de 2018 por meio de entrevistas semiestruturadas com 16 usuários indicados por agentes comunitários de saúde. Os resultados iluminaram a confiança como um valor-fonte da experiência de produção do cuidado, oportunizada pela valorização de um modo de fazer medicina de base que tem como farol o processo de rotina e a formação de vínculo. Concluiu-se que, sem um conhecimento prolongado, dirigido para relações simétricas, não se consolidam as garantias necessárias para a realização do tão caro encontro entre confiante (usuário) e confiável (médico) na Atenção Básica.
Aportes da teoria crítica da tecnologia à análise da inovação nos serviços de saúde
Authors: Costa Laís Silveira
Published: July 2020

Este artigo tem como objetivo refletir sobre os limites do campo da inovação nos serviços de saúde à luz da teoria crítica da tecnologia (TCT). Ao considerar o potencial da inovação social para o entendimento de como as mudanças poderiam atender públicos menos restritos – e, portanto, mais condizentes com o campo da Saúde Coletiva –, o estudo problematiza a validade da resistência proposta por este instrumental teórico no contexto brasileiro. Desenvolvido a partir da revisão de literatura, o trabalho aporta uma releitura dos limites teóricos do campo e inova ao avaliar a validade dos canais de resistência propostos pela TCT no contexto brasileiro. A conclusão da presente análise reafirma o diagnóstico das relações de influência e valores da TCT, mas identifica adequações necessárias à aplicação dessas soluções nos países menos desenvolvidos.

A Case Study on Two-Span Post-Tensioned Concrete Bridge Decks with Different Span Lengths and Investigation on Prestressing Tendons with Comparisons
Authors: TURAN Mustafa
Published: July 2020

Post-Tensioned (PT) concrete system is one of the widely used bridge superstructure types because of its better load capacity performance. By increasing load carrying capacities on conventional reinforced concrete structures, PT is considered as an advanced technology in engineering. The aim of this paper is to study on finite element analysis of two-span PT concrete bridge decks with different span lengths. For three different span lengths, two-span bridge decks were investigated. To reduce the self-weight of the deck, at mid spans, deck section was used as voided section and at diaphragm regions, section was used as filled. Two-dimensional Finite Element (FE) deck models were created by frame elements. The FE software package Midas Civil was used. Permanent, transient and time-dependent loading types were considered. Boundary conditions were defined with their real mechanical properties. To balance the deck section stresses, prestressing tendons were used. By iterations, PT tendons layout and types were studied. Interaction between span lengths and PT tendons areas was investigated. Also, different effects on PT tendons were studied and relevant comparisons were submitted. The “best” tendon using was examined for the investigated deck sections. Concluded that optimization on PT tendon areas at bridge deck sections is possible by investigating the main effects on it. Results show that a good optimization enables us to have the optimal PT tendon using with lower cost.

In this study, the response to geomagnetic storms of the ionospheric F2 layer critical frequency (foF2) was investigated at the magnetic conjugate points. The hourly foF2 data observed at the magnetic conjugate points of middle and high latitudes for the geomagnetic stormy days around both of 1976 and foF2 data received from IRI-2016 Model for same points were used. The foF2 data observed in magnetic conjugate points and received from IRI Model were examined using the superposed epoch analysis method and the results obtained were compared. From the results of analysis, it was observed that the foF2 data observed at magnetic conjugate points and received from IRI Model simultaneously respond to geomagnetic activity changes for both the middle latitudes and the high latitudes.
Optimization of Back-Surface Field for Crystalline Silicon Solar Cells and Estimating the Firing Temperature depending on the Amount of Printed Aluminum
Authors: KANMAZ İmran , ÜZÜM Abdullah
Published: July 2020

Optimization of the back surface field (BSF) for crystalline silicon solar cells was carried out by Afors-Het simulation software. Thickness and doping concentration parameters were optimized and electrical parameters of solar cells both with BSF and non-BSF were analyzed. The optimum BSF thickness and doping concentration for the crystalline silicon solar cell were determined as 7 µm and 1x1019 cm-3, respectively. A special attention was given to the estimation of peak firing temperature considering the printing amount of aluminum paste in order to form an optimal BSF by the calculations using Al-Si binary phase diagram. It was concluded that the temperature of up to 950oC should be established if an amount of 3 mg/cm2 printed aluminum was used to achieve BSF thickness of 7 µm, where 775 oC would be enough when the amount of aluminum is 8 mg/cm2.

Authors: BİLBEY Buse , EROL Gamze , BÜYÜKAKSOY Aligül
Published: July 2020

The most widely used solid oxide fuel cell (SOFC) anodes, nickel-yttria stabilized zirconia (NiO-YSZ) composites, are generally fabricated by co-sintering of NiO and YSZ powders. In this study, to achieve a longer triple phase boundary length, these composites were fabricated from powders synthesized via an ethylene glycol-based Pechini method. Polymeric precursors of NiO and YSZ were prepared separately and then mixed, dried and calcined 600, 700 and 800°C for 4 hours, in air. NiO and YSZ crystals with average sizes of 26 and 7 nm, respectively were achieved upon calcination at 600 °C. With increasing heat treatment temperature, both the crystal and agglomerate sizes increased, which, in turn, an increased the anode polarization resistances. Electrochemical activities comparable to or higher than anode prepared by co-sintering of powder mixtures were achieved in the anodes prepared by sintering of the composite powders.
Non-Markovian Corrections to Quantum Regression Theorem for the Strong Coupling Spin-Boson Model
Authors: KURT Arzu
Published: July 2020

We report the results of an investigation of the effects of non-Markovian corrections to the dynamics of two-time correlation functions of the strong interaction spin-boson model. Beyond quantum regression theorem corrections are taken into account at the low environmental temperatures for a two-level system (TLS) which is in contact with a structured bath. The results indicate that the corrections lead to appreciable (small) quantitative (qualitative) differences for both biased and non-biased TLS settings.
SOSIAL-RITUAL DAN SIMBOLIK-MISTIK PADA PAWON (Studi kasus: Arsitektur Kasepuhan Ciptagelar-Sukabumi)

Penelitian ini dilatarbelakangi oleh fenomena pawon yang sarat dengan fungsi sosial dan ritual dan erat hubungannya dengan makna simbolik-mistik. Tujuaan penelitian ini secara umum mendeskripsikan dan mengungkap fungsi dan makna pawon. Lokasi penelitian di kampung Kasepuhan Ciptagelar sebagai prototype masyarakat Sunda. Metode yang digunakannya adalah etno-arsitektur. Hasil penelitian menunjukkan bahwa pawon pada arsitektur rumah masyarakat Sunda memiliki dua dimensi penting: (1) Fungsi sosial; Sebagai wadah untuk aktivitas bersosialisasi para wanita, seperti: memasak, mengobrol, mendengarkan radio,  menonton  televisi, tiduran, menidurkan anak, serta mencari kutu. Maknanya terungkap dalam kalimat: "pawon jantungna imah, keur hirup jeung huripna manusa", artinya dapur merupakan pusatnya rumah bagi aktivitas hidup dan kehidupan penghuninya; (2) Fungsi ritual; Sebagai 'jembatan' penghubung komunikasi dengan para karuhun melalui sesajen dan mantera-mantera yang disimpan di dalam goah atau padaringan untuk memohon keselamatan dan berkah. Maknanya tersurat dalam kalimat: “pangeling-eling” artinya sebagai peringatan, apabila seseorang meninggal, maka arwahnya tinggal di pawon selama tujuh hari, kemudian pindah ke atas suhunan selama empat puluh hari. Oleh karena itu, anggota keluarga yang ditinggalkan harus mengiringinya dengan doa agar arwah segera diterima oleh Yang Maha Kuasa.
Projective lattices of tiled orders
Authors: Zhuravlev V. , Tsyganivska I.
Published: July 2020

Tiled orders over discrete valuation ring have been studied since the 1970s by many mathematicians, in particular, by Yategaonkar V.A., Tarsy R.B., Roggenkamp K.W, Simson D., Drozd Y.A., Zavadsky A.G. and Kirichenko V.V. Yategaonkar V.A. proved that for every n > 2, there is, up to an isomorphism, a finite number of tiled orders over a discrete valuation ring O of finite global dimension which lie in $M_n(K)$ where K is a field of fractions of a commutatively discrete valuation ring O. The articles by R.B. Tarsy, V.A. Yategaonkar, H. Fujita, W. Rump and others are devoted to the study of the global dimension of tiled orders. H. Fujita described the reduced tiled orders in Mn(D) of finite global dimension for n = 4; 5. V.M. Zhuravlev and D.V. Zhuravlev described reduced tiled orders in Mn(D) of finite global dimension for n = 6: This paper examines the necessary condition for the finiteness of the global dimension of the tile order. Let A be a tiled order. The kernel of the projective resolvent of an irreducible lattice has the form M1f1 +M2f2 + ::: +Msfs, where Mi is irreducible lattice, fi is some vector. If the tile order has a finite global dimension, then there is a projective lattice that is the intersection of projective lattices. This condition is the one explored in the paper.

Authors: Grigorenko A. , Borysenko M. , Boychuk O.
Published: July 2020

The natural frequencies and the corresponding vibration modes of open cylindrical shells with an elliptical cross-section and variable thickness are analyzed. Various opening angle of the shell along both the minor and major axes are allowed and various boundary conditions are considered. The numerical solutions are obtained using the finite element package FEMAP with the NASTRAN solver. A number of lowfrequency vibrations are investigated in terms of their dependence on the opening angle along major and minor axes of the shell. The vibration forms for the first ten frequencies with different boundary conditions at the same opening angles are shown.
Approximate method of solving one periodic optimal regulated boundary value problem
Authors: Askerov I.
Published: July 2020

In the present work we considered the solution of one periodic optimal regulated boundary value problem by the asymptotic method. For the solution of the problem with extended functional writing, boundary conditions and Euler-Lagrange equations were found. The approach to the solution of the problem depending on a small parameter by seeking a system of nonlinear differential equations and solving Euler-Lagrange equations, the solution of the general problem in the first approach comes down to solving two nonlinear algebraic equations.

Published: July 2020

E-Government is a set of pervasive technologies and automated processes now. The open data plays a crucial role in the successful implementation of this concept. The Open Data Platform (ODP) architecture is described here as the framework for the open data access systems implementation, including specific requirements. The proposed architecture and its components were discussed in this paper in detail for its availability, productivity, and reliability. The open data subsystem based on the architecture presented here was developed for the Jordan Government and was successfully implemented and tested. Thus, this architecture showed its viability.

The focus of the paper is the detailed analysis of the proposed ODP architecture and its characteristics. The ODP is a significant system for the mature e-Government. We propose here the architecture for it with usage-proven characteristics. This fact adds the value to the e-Government framework stability, and significant characteristics and improves the overall quality of the system.

No tribunal de Isaac Bashevis Singer
Authors: Judensnaider Ivy
Published: July 2020

Este artigo analisa a vida familiar que o escritor polonês Isaac Bashevis Singer encena em No tribunal de meu pai. A partir da perspectiva autobiográfica, o autor narra casos levados para julgamento de seu pai no Beit Din que funcionava em Varsóvia, e reconstrói a vida nessa cidade e em Bilgoray, para onde a família se transferiu durante a Primeira Guerra Mundial. Por meio do passado resgatado por Singer, pretendemos explorar a vida da comunidade judaico-polonesa nos primeiros anos dos Novecentos e levantar subsídios que nos permitam compreender o contexto no qual ela estava imersa. Singer não apenas julga o pai, a família, a si mesmo e os casos trazidos ao tribunal rabínico. Ao longo da narrativa, Singer instaura o seu próprio Beit Din: ali, o verdadeiro objeto de julgamento são as primeiras décadas do século 20 e a rede de influências filosóficas, religiosas, políticas e científicas que permearam o judaísmo do leste europeu no período anterior ao Shoah.
Imoralidade, instabilidade, capitalismo e judeus em "Angústia", de Graciliano Ramos
Authors: Muraca Márcio Henrique
Published: July 2020

Por meio do protagonista Luís da Silva, do romance Angústia (1936), de Graciliano Ramos, é possível ver a relação pecado-culpa-castigo, em função de sua percepção do sistema capitalista como imoral. Moisés, um dos amigos de Luís, é personagem que aparece articulado a essa tensão no pensamento crispado do narrador: há conceitos antijudaicos nele, como a ligação “judeus-comunismo”, “judeus-capitalismo” e “judeus-ateísmo”. O ressentimento é consequência da opressão que Luís da Silva percebe em sua vida, na qual se vê impossibilitado de realizar um projeto de estabilidade/constância – em sentidos diversos.

: Pseudomonas aeruginosa is an important cause of multidrug-resistant nosocomial infections. The knowledge of resistance mechanisms in Pseudomonas is an important issue for antimicrobial treatment. Therefore, the objective was to detect carbapenems resistance in P. aeruginosa by phenotypic methods and genes (blaIMP and blaVIM) coding for carbapenemase resistance.

The study conducted in the Department of Microbiology, BMCRI, Bengaluru. 91 samples from the patients hospitalised for 48 hours and more were processed. Carbapenem resistant P. aeruginosa (CRPA) were identified by biochemical tests and by Kirby Bauer Disk diffusion method as per CLSI guidelines. Those carbapenem resistant isolates were further subjected to two MBL detecting phenotypic tests- Modified Hodge Test (MHT) and Combined disk Test (CDT) by using imipenem and imipenem/ EDTA disk and MBL genes (blaIMP and blaVIM) were identified by PCR.

91 clinical isolates were identified as CRPA, 92.3% isolates were positive by CDT whereas only 13.2% of isolates showed positive by MHT method indicating MBL production. Among 91 strains, 19.04% strains were harbouring blaVIM and 1.2% strain harbouring blaIMP gene.

The detection of MBL-producing P. aeruginosa help in appropriate antimicrobial therapy and avoid development and dissemination of these strains. Hence routine detection of MBL production in P. aeruginosa should be undertaken. All CRPA isolates should be routinely screened for MBL production using CDT and positive isolates should be confirmed by PCR. MHT test had low sensitivity. To understand the epidemiology, there is a need of genetic analysis and typing of MBL enzymes.

Published: July 2020

The hydrolysis-reduction of hemicellulose arabinogalactan to arabitol and galactitol polyalcohols, which are widely used in the food and pharmaceutical industries, was studied. It was shown that the process could be performed with the bifunctional catalyst containing highly dispersed ruthenium deposited on the cesium salt of silicon-tungsten heteropolyacid, Ru/Cs3HSiW12O40. The catalysts with different content of ruthenium (0.3, 0.6 and 1 wt.%) were synthesized for the study. The catalysts and their Cs3HSiW12O40 support were examined by various physicochemical methods (low-temperature nitrogen adsorption, IR spectroscopy, XRD, and TEM). The effect of temperature, substrate/catalyst ratio and ruthenium content in the catalyst on the yields of target products was elucidated. The highest yields of target products were achieved at the metal content of 0.6 wt.% and equal weights of the loaded catalyst and substrate (the 1:1 ratio). At a temperature of 200 °C, arabitol and galactitol can be produced with the yields up to 12 and 48 % for 2 h of the reaction in the presence of catalyst with the composition 0.6%Ru/Cs3HSiW12O40.
Heterogeneous Biocatalytic Processes of the Low-Temperature Synthesis of Esters: Selection of Organic Solvent
Authors: Kovalenko G. A. , Perminova L. V.
Published: July 2020

Processes of the low-temperature enzymatic synthesis of esters in nonaqueous media of organic solvents with participation of heterogeneous biocatalysts synthesized by the adsorption immobilization of a recombinant lipase from Thermomyces lanuginosus (Pichia pastoris producer) on macroporous carbon aerogel were investigated. The esterification reaction was conducted using individual organic solvents of different polarity, such as nonpolar ones (lоgP > 2.5) – hexadecane, hexane and toluene, and polar solvents (lоgP < 1) – diethyl ether, tert-butanol and acetone, as well as their binary mixtures of different composition, for example, a mixture of hexane with diethyl ether having the composition 1 : (1/5÷3, vol. fr.). The effect of the solvent and co-solvent nature on the properties of synthesized biocatalysts, namely the enzymatic activity and operational stability, was studied in the batch esterification of heptanoic acid (C7:0) by alcohols, particularly the polar substrates – ethanol and n-butanol, or nonpolar alcohols – n-octanol and n-hexadecanol. Activity of the synthesized biocatalysts was found to depend to a great extent on polarity of both the solvents used in the reaction and the alcohol substrates. The maximum activity of 400 EA·g–1 was observed in a medium of nonpolar and nonviscous hexane (lоgP = 2.9), whereas the minimum activity of 4 EA·g–1 – in acetone (lоgP = 0.4); esterification of heptanoic acid in the presence of tert-butanol (lоgP = 0.6) virtually did not proceed. The activity of biocatalysts was shown to depend nonmonotonically on the lоgP value of individual solvent. In the binary mixtures of organic solvents, such as hexane/diethyl ether, biocatalytic activity linearly increased with an increase in lоgPmixture; in addition, biocatalysts exhibited the maximum operational stability.
