Published: December 2019

Tıbbi ve aromatik bitki kültüründe karşılaşılan
sorunları çözmek, araştırmayı bir bütün olarak ele almak, bu çalışmaları
düzenlemek ve çalışan insanlar ve kurumlar arasında koordinasyonu sağlamak
amacıyla 1990 yılında T.C. Tarım ve Orman Bakanlığı tarafından Tıbbi ve
Aromatik Bitkiler Ulusal Araştırma Projesi başlatılmıştır. Bu çalışmaların
temel amacı, Türkiye'deki tıbbi, aromatik ve boya bitkilerinde farklı
endüstrilerin ihtiyaç duyduğu standart ve kaliteli hammaddelerin üretimi için
yeni bitki türleri yetiştirerek tescilli çeşitlerin geliştirilmesidir.
Türkiye'nin farklı bölgelerinde bulunan araştırma enstitüleri ekolojilerine
uygun kültür bitkilerini seçerek ıslah ve çeşit geliştirme çalışmalarına
yapmaktadırlar. Bitkilerde aktif maddelerin belirlenmesi için kalite
çalışmaları agronomi çalışmaları ile bütünleştirilerek ıslah çalışmaları daha
verimli hale getirilmiştir. Bu çalışmalar sonucunda şu ana kadar 15 türe ait 41
çeşit tıbbi ve aromatik bitki çeşidi tescil edilmiştir. Bu türlerin üretim
alanları her yıl artmaktadır. 2018 yılında yaklaşık 100.000 hektar
alanda 300.000 ton şifalı ve aromatik bitki üretilmiştir. Bu üretimin 50.000
tonu ihraç edilmiş ve 265 milyon ABD doları gelir sağlanmıştır. Bundan sonraki
süreçte kültür, ıslah, yetiştirme ve kalite çalışmalarının sürdürülmesi ve yeni
çeşitler geliştirilerek bu çeşitlerin üretim ve kullanım alanlarının
artırılması hedeflenmektedir. Öte yandan, 2050 yılında 5 trilyon ABD dolarına
ulaşması beklenen dünya bitkisel ilaç pazarından daha fazla pay alabilmek için
ham drog ihracatı yerine işlenmiş ürünlerin ihracatına öncelik verilmesi planlanmaktadır.

Published: December 2019

В мировой науке изучение процесса активного долголетия началось относительно недавно – в Европе попытки комплексного количественного анализа процесса активного долголетия впервые были предприняты в 2010 г. Целью данной работы является количественная оценка процесса активного долголетия в Сибирском федеральном округе. Авторы выявили методологические проблемы применения международной методики оценки активного долголетия для России и отдельных регионов. Методы: метод индексной оценки социально-экономических процессов, формирующих основу активного долголетия, в частности Индекс активного долголетия (Active Ageing Index). Для иллюстрации отдельных выводов дополнительно использованы данные опросов людей старшего поколения Томской области и результаты экспертных семинаров, проведенных Международной лабораторией улучшения технологий благополучия пожилых людей ТПУ с участием пенсионеров и социальных работников. Результаты. Проведенные оценки индикаторов и доменов Индекса активного долголетия позволили выявить наличие нереализованного потенциала активного долголетия в Сибирском федеральном округе. Значительные негативные отклонения от среднероссийских значений наблюдаются в отношении занятости пожилых людей, отсутствия риска бедности, физической безопасности и включенности в социальные связи. Вместе с тем Сибирь показывает более вы высокие результаты по физической активности, относительному среднему доходу и отсутствию сильной материальной депривации. Показатели финансовой обеспеченности пенсионеров Сибирского федерального округа свидетельствуют об их относительном благополучии на фоне молодого поколения, однако низкие доходы по региону в целом создают предпосылки для высокого риска бедности.

Varietal specificity of polyphenols, free phenolics and antioxidant potential in hops
Authors: Mikyška Alexandr , Jurková Marie
Published: December 2019

Many studies have confirmed hops (Humulus lupulus L.) as the source of a number of physiologically active polyphenols, important for both brewing and potentially pharmaceutical purposes. The three-year screening of polyphenols and 23 free phenolics profile (HPLC/coulometric detection) showed a significant association of polyphenols and free phenolics with DPPH antioxidant potential and the genetically determined specificity of free phenolics composition in hops. Varieties of American origin have a different profile compared to European varieties. For the first time, the free phenolics hydroxycoumarins were detected in hops. The DPPH strongly correlated with total polyphenols and flavanoids (n = 95, r = 0.92, 0.93 respectively) and correlated negatively with alpha acids (n = 95, r = -0.73). The polyphenols and the DPPH decrease with increasing alpha acids both among varieties and within one variety. These findings can serve as a useful tool for hop selection in brewing or pharmaceutical production.
David Neves: projetos de vida e autonomia do crítico-cineasta
Authors: Pinto Pedro Plaza
Published: December 2019

O objetivo deste estudo é considerar a partilha do projeto ideológico do cineasta David Neves em direção à autonomização dos elementos de seu projeto estético durante uma década, até o final dos anos 1960. Conforme a separação esclarecedora entre projeto estético e ideológico proposta por João Luiz Lafetá  ao estudar o modernismo dos anos 1930, o caso do David Neves demonstra-se particular em relação ao Cinema Novo. No primeiro momento, a formação do crítico-cineasta e sua estreia nas letras apontam para a emergência de paradigmas estéticos próprios ou mimetizados de figuras admiradas. No segundo momento, há o eclipse destes aspectos em favor da batalha pelo Cinema Novo. Contudo, a estreia como diretor de longas-metragens retoma a sua distinção e promove o jovem ao quadro próprio da sua intervenção. O estudo das críticas e da posição intelectual de David Neves esclarecem a sua dupla contribuição no período. O fio da meada é desenrolado através de necrológio publicado como escrito de crítica cinematográfica deste que foi efetivamente um crítico-cineasta. A abordagem seleciona segmentos da vida do realizador através do destaque de biografemas e das suas relações com o movimento Cinema Novo.
Refrações do conceito de filme de cinema na obra de Rogério Sganzerla
Authors: Machado Irene de Araújo , Fonseca Daniel Felipe Espinola Lima
Published: December 2019

O artigo examina o pensamento crítico-criativo do cineasta Rogério Sganzerla (1946-2004), cruzando sua produção teórica com procedimentos construtivos de O Bandido da Luz Vermelha (1968), sua estreia na direção de longas-metragens. Trabalha-se com a hipótese de que o olhar para o sistema de sua produção revela, para além de uma aplicação de suas formulações críticas em sua obra fílmica, o modo como seu pensamento se configura de modo a considerar a dialogia – quer seja num nível da tessitura das relações críticas e metalinguísticas propostas, quer seja no âmbito da diegese – como elemento implícito na organização de um sistema teórico-crítico-criativo.

Published: December 2019

Buscou-se construir e demonstrar uma ferramenta desenvolvida a fim de reduzir o aspecto subjetivo inerente à classificação arquivística, tornando-a mais consistente. Tendo-se em conta que erros de classificação podem prejudicar a grande maioria das funções arquivísticas, especialmente a avaliação e a descrição, foi elaborado um software denominado Ontological Classifier (OntoClass). Esse software, por meio da criação de uma ontologia a partir do plano de classificação de uma entidade produtora de documentos, é capaz de determinar a classe à qual um documento pertence com base em termos autorizados dispostos em uma lista. A fundamentação teórica foi realizada por meio de uma pesquisa bibliográfica e o desenvolvimento da ferramenta foi feito com uso da linguagem de programação Python 3.7 e da linguagem de consulta SPARQL. A partir de testes realizados com uma ontologia simples criada especificamente para este trabalho, conclui-se que o OntoClass alcança seu objetivo, apesar de ainda serem necessários testes em situações reais e apesar de haver alguns requisitos a cumprir para obter resultados positivos de sua utilização.
Volunteer activity among the elderly: features and participation motives
Authors: Butueva Zinaida A.
Published: December 2019

The year 2018, which was declared the year of the volunteer in Russia, aided in the emergence of such a phenomenon as “silver” volunteerism. This article presents an analysis of the volunteer activity of elderly folk, its features and their participation motives. Volunteerism is conditioned by the potential of an increasingly socially active lifestyle among the elderly, who are prepared to partake in social practices for the benefit of society. Russia’s recently accepted legal documents which regulate volunteerism are aimed at active longevity. Literature and mass-media are mentioning the term “silver” volunteerism more frequently. The author of this article has undertaken the task of defining its meaning. “Silver” volunteerism is considered to be a type of active and ethical life activity for the elderly, which is performed at no cost and for the good of other people, aids in the elderly feeling a connection to community life, as well as sharing their life and professional experience, and which has become one of the conditions for enhancing their sense of dignity, for improving their social well-being, health and independence. The conducted sociological study of volunteer practices among the elderly states that the degree to which they participate in the activities of volunteer organizations varies depending on gender, age, health condition, income, education level and social-professional status. Their primary motives for participating in volunteer activity are as follows: the desire to feel competent, regardless of age; staying in touch with other people; putting their free time to use and escaping a sense of loneliness. For most elderly people, participating in volunteer practices is conditioned by a person’s need to satisfy their personal, individual need to be useful to someone else, as well as their intention to solve their own problems of material and psychological nature. The social portrait of a “silver” volunteer was compiled based on the results of this study. These are mostly women ages 60 to 69, who have a college education, children, and who live by themselves. Most of the respondents are of average material status. A conclusion is drawn that developing volunteer activity among the elderly creates new opportunity for expressing one’s creative potential and social activeness in later stages of life.
Ricardo Piglia e a tradução
Authors: Grotto Livia
Published: December 2019

Segundo o Ricardo Piglia de Las tres vanguardias, quando um escritor argentino encontra um “modo de usar” as outras culturas, alcança, ao mesmo tempo, uma “identidade” no interior do sistema literário nacional. Esse “modo de usar” englobaria vários tipos de relação com o material estrangeiro, incluindo os extremos de torná-lo completamente palatável ou totalmente irreconhecível. O estrangeiro também poderia ser imitado, parafraseado ou relido segundo novos matizes. Este ensaio se centra na figura do tradutor Ricardo Piglia, com um breve percurso por suas facetas de editor e divulgador de romances policiais hard-boiled na Argentina.
Da filiação do pesquisador à filiação do escritor
Authors: Pino Claudia Amigo
Published: December 2019

Neste artigo, fazemos uma narrativa da passagem de Roland Barthes da crítica para a escrita literária, a partir da análise das anotações manuscritas do seu seminário “A noção de idioleto”, oferecido em 1970-1971, na École de Hautes Études em Sciences Sociales. Para isso, tentamos entender a sua mudança de filiação, em um primeiro momento centrada sobretudo em referências teóricas (como a linguística da enunciação, a semiologia e a estilística) e, depois, em uma única referência literária: Bouvard e Pécuchet, de Gustave Flaubert. Este texto faz parte de um projeto mais amplo, que propõe a narrativa de todos os seminários oferecidos na École por Roland Barthes, entre 1962 e 1977, a partir do arquivo de Roland Barthes, na Biblioteca Nacional da França.

A rota da transregionalização, da transnacionalização e dos oligopólios educacionais na educação a distância no Maranhão
Authors: Nascimento Alberico Francisco do
Published: December 2019

O artigo aborda a transregionalização, a transnacionalização e os oligopólios educacionais focados na Educação a Distância, como uma expressão da financeirização do capital na educação superior, referenciada pelas premissas neoliberais que orientam a reprodução do capital. O processo de construção teórico-prático deste estudo partiu do pressuposto de que esse fenômeno só pode ser compreendido a partir de uma perspectiva de análise que o considera como uma totalidade concreta. Dessa forma, o universo de investigação foi composto por todas as Instituições de Ensino Superior que ofertam Educação a Distância no Maranhão e os dados foram coletados a partir de consultas no portal do Cadastro Nacional de Cursos e Instituições de Educação Superior - Cadastro e-MEC e nos documentos públicos sobre Educação a Distância. Os resultados indicaram que a massificação da Educação a Distância no Maranhão é um fenômeno concreto e que esse estado é rota crescente dos oligopólios educacionais transregionais e transnacionais, fomentados pelo grande capital em busca de alta lucratividade.

Authors: Li Xing , Matsumoto Tomohiro , Takuwa Miho , Saeed Ebrahim Shaikh Ali Mahmood , Hirabayashi Takumi , Kondo Hiroyo , Fujino Hidemi
Published: December 2019

Abstract: Ultraviolet (UV) induces skin photoaging, which is characterized by thickening, wrinkling, pigmentation, and dryness. Astaxanthin, a ketocarotenoid from Haematococcus pluvialis, has been extensively studied with respect to its possible effect on skin health as well as UV protection. In addition, astaxanthin attenuates increases in the generation of reactive oxygen species (ROS) and capillary regression of skeletal muscle. In the present study, we investigated whether astaxanthin would protect UV-induced photoaging and capillary regression in the skin of HR-1 hairless mice. UV induces wrinkle formation, thickness and capillary regression in dermis of hairless mice and the administration of astaxanthin decreased the UV-induced wrinkle formation, skin thickness, and increase in collagen fibers in skin. Astaxanthin supplementation also inhibited the levels of ROS generation and attenuated the decreases in wrinkle formation, thickness and capillary number in the skin. We also found an inverse correlation between wrinkling and capillary number, and the photoaging associated with capillary regression in skin. These results suggest that astaxanthin can protect against photoaging caused by ultraviolet irradiation and the effects of astaxanthin in photoaging inhibition may be associated with the protection of capillary regression in skin.

Published: December 2019

Biofilm-mediated infection is a major cause of bone prosthesis failure. The lack of molecules able to act in biofilms has driven research aimed at identifying new anti-biofilm agents via chemical screens. However, to be able to accommodate a large number of compounds, the testing conditions of these screenings end up being typically far from the clinical scenario. In this study, we assess the potential applicability of three anti-biofilm compounds (based on natural compounds) as part of implanted medical devices by testing them on in vitro systems that more faithfully resemble the clinical scenario. To that end, we used a competition model based on the co-culture of SaOS-2 mammalian cells and Staphylococcus aureus (collection and clinical strains) on a titanium surface. Additionally, we studied whether these derivatives of natural compounds enhance the previously proven protective effect of pre-incubating the titanium surface with SaOS-2 cells. Out of the three tested leads, one showed the highest potential, and can be regarded as a promising agent for incorporation into bone implants. This study emphasizes and demonstrates the importance of using meaningful experimental models, where potential antimicrobials ought to be tested for protection of biomaterials in translational applications.
The sex Differences in Blood Pressure and Cardiac Autonomic Modulation during the Menopause Transition at Rest and after Aerobic Exercise Training
Authors: Ferreira Maycon Jr , Esposti Rodrigo D. , Jarrete Aline O. , Sponton Carlos H. G. , Zanesco Angelina
Published: December 2019

Background: Sex differences in blood pressure (BP) exist during all reproductive life between women and men whereas a sharper increase in BP occurs after menopause which is associated with increased prevalence of cardiovascular diseases. This study examined cardiovascular and biochemical parameters in perimenopausal women (PW) aiming to investigate the influence of sex on a) office BP and for 24 hours; b) cardiac autonomic modulation; c) redox state by measuring MDA, SOD, and catalase; d) NOx- concentration. In addition, aerobic exercise training (AET) was applied for detecting changes in cardiovascular responsiveness during the menopausal transition. Methods: Thirty-one participants were enrolled, healthy PW and age-matched men. Cardiovascular and biochemical biomarkers were evaluated at baseline and after AET (8 weeks of exercise on a treadmill, three sessions/week, duration of 30-40 minutes). Results: At rest, PW presented: a) a lower diastolic BP during daytime; b) a lower absolute and normalized LF component as well as a higher HF normalized component; d) no sex differences for redox biomarkers and NOx- concentration. After AET, only PW was responsive in lowering systolic BP that was accompanied by an increase in NOx- concentration and SOD activity. Regarding HRV, both groups were responsive to the AET. Conclusions: During the menopausal transition, systolic BP was similar to men whereas cardiac autonomic modulation remained unaltered showing the influence of sex steroids on BP. In Addition, AET was fundamental during the menopause transition by preventing an elevation in BP, minimizing the effects of aging associated with estrogen deficiency on women's cardiovascular health.
Evaluation of effectiveness of CO2 sequestration in geological reservoir based on Unified Pipe-network Method
Authors: Yan Xiao , Sun Zizheng , Li Shucai , Yang Weimin , Zhang Yiming
Published: December 2019

The underground injection and geological sequestration of carbon dioxide (CO2) is a promising approach for reducing the levels of CO2 in the atmosphere. To mitigate the leakage of CO2 resulting from natural fracture networks in rock masses, the sequestration process is commonly accompanied by the injection of reactive Portland cement representing a coupled hydro-chemo-mechanical process. In this work, a numerical approach based on the unified pipe network method (UPM) is presented that considers the coupled permeation and diffusion processes with chemical precipitation. Most input parameters are derived from the published literature. The proposed approach is validated through a comparison with analytical solutions, which are applied to simulate the CO2 sequestration process in a fractured rock mass. The results indicate that the long-term sequestration effect, which is highly influenced by the fracture distribution, can be captured effectively by the model. Consequently, the presented approach can assist engineers in properly designing the arrangement of boreholes and determining the concentration of the grouting material.
Investigating Strength that Comprehensive mRNA Expression Level of Prognostic Genes Influences on Patient Survival for Every Cancer Type
Authors: Lee Minhyeong
Published: December 2019

This study aimed to rank cancers by the strength of relationship between comprehensive mRNA expression of the most harmful or protective genes and patient survival. Using TCGA dataset including RNA-SEQ and clinical data, we investigated not only gene specific prognostic availability, but also comprehensive prognostic availability of prognostic genes filtered by cox coefficient, and ranked cancers by specially designed prognostic indicator. Through Kaplan-Meier plots, we checked that cancers vary in the strength of influence of prognostic genes, and they follow as the rank. Developing treatment with method to reduce or increase expression of biomarkers for specific cancer which ranked bottom, it would be not efficient in high probability. The results of this study can be a scientific evidence for that.

Published: December 2019

In this research we are reporting gas sensing properties of TiO2-x/TiO2-based hetero-structure, which was ‘self-heated’ by current that at constant potential passed through the structure. Amperometric measurements were applied for the evaluation of sensor response towards ethanol, methanol, n-propanol and acetone gases/vapors. The sensitivity towards these gases was based on electrical resistance changes, which were determined by amperometric measurements of current at fixed voltage applied between Pt-based contacts/electrodes deposited on TiO2-x/TiO2-based layer. XRD analysis revealed the formation of TiO2-x/TiO2-based hetero-structure, which is mainly based on Ti3O5/TiO2 formed during hydro-thermal oxidation based sensing layer preparation process. Additionally, photoluminescence and time-resolved photoluminescence decay kinetics based signals of this sensing structure revealed the presence of TiO2 mainly in the anatase phase in the TiO2-x/TiO2-based hetero-structure, which was formed at 400°C annealing temperature. The evaluation of TiO2-x/TiO2-based gas sensing layer was performed at several different temperatures (25°C, 72°C, 150°C, 180°C) and at these temperatures different sensitivity to aforementioned gaseous materials was determined.
Investigating Multiwavelength Lognormality with Simulations: Case of Mrk 421
Authors: Chakraborty Nachiketa
Published: December 2019

Blazars are highly variable and display complex characteristics. A key characteristic is the flux distribution or flux PDF whose shape depends upon the form of the underlying physical process driving variability. The BL Lacertae, Mrk 421 is one of the brightest and most variable blazars across the electromagnetic spectrum. It has been reported to show hints of lognormality across the spectrum from observed histograms of radio to gamma-ray fluxes. This would imply that the underlying mechanisms may not conform to the "standard" additive, multi-zone picture, but could potentially have multiplicative processes. This is investigated by testing the observed lightcurves at different wavelengths with time-series simulations. We find that the simulations reveal a more complex scenario, than a single lognormal distribution explaining the multiwavelength lightcurves of Mrk 421.

Authors: Kozdrowski Stanisław , Zotkiewicz Mateusz , Sujecki Slawomir
Published: December 2019

Ultra-wideband wavelength division multiplexed networks enable operators to use more effectively the bandwidth offered by a single fiber pair and thus make significant savings, both in operational and capital expenditures. The main objective of this study is to minimize optical node resources, such as transponders, multiplexers and wavelength selective switches, needed to provide and maintain high quality of network services, in ultra-wideband wavelength division multiplexed networks, at low cost. A model based on integer programming is proposed, which includes a detailed description of optical network nodal resources. The developed optimization tools are used to study the ultra-wideband wavelength division multiplexed network performance when compared with the traditional C-band wavelength division multiplexed networks. The analysis is carried out for realistic networks of different dimensions and traffic demand sets.
Development and Assessment of an Integrated 1D-3D CFD Codes Coupling Methodology for Diesel Engine Combustion Simulation and Optimization
Authors: Millo Federico , Piano Andrea , Peiretti Paradisi Benedetta , Marzano Mario Rocco , Bianco Andrea , Pesce Francesco C.
Published: December 2019

In this paper an integrated methodology for the coupling between 1D- and 3D-CFD simulation codes is presented, which has been developed to support the design and calibration of new diesel engines. The aim of the proposed methodology is to couple 1D engine models, which may be available in the early-stage engine development phases, with 3D predictive combustion simulations, in order to obtain reliable estimates of engine performance and emissions for newly designed automotive diesel engines. The coupling procedure features simulations performed in 1D-CFD by means of GT-SUITE and in 3D-CFD by means of Converge, executed within a specifically designed calculation methodology. An assessment of the coupling procedure has been performed by comparing its results with experimental data acquired on an automotive Diesel engine, considering different working points including both part load and full load conditions. Different multiple injection schedules have been evaluated for part-load operation, including pre and post injections. The proposed methodology, featuring detailed 3D chemistry modeling, was proven to be capable to properly assess pollutant formation, specifically to estimate NOx concentrations. Soot formation trend was also well-matched for most of the explored working points. The proposed procedure can therefore be considered as a suitable methodology to support the design and calibration of new Diesel engines, thanks to its ability to provide reliable engine performance and emissions estimations from the early-stage of a new engine development.

PANDANGAN PENGARANG ATAS BURUH MIGRAN INDONESIA DALAM NOVEL SUMAYYAH KARYA NIZAR ABADZAH
Authors: Hidayah Nur
Published: December 2019

Indonesian Migrant Workers are Indonesian workers who work abroad. They must leave Indonesia at a productive age, by leaving various social problems to bear the burden of solving family economic problems and providing foreign exchange for the country. These foreign exchange heroes in the country where they work are seen as tools to get work done, and not as human beings who need privacy, protection, respect and other human needs. This view has caused many problems, both psychological and social problems that have not been resolved until now, especially for migrant workers who work in the domestic sector, as happened to Marruni, a character of migrant worker in the novel of Sumayyah by NizarAbadzah. Abadzah is seen as a character who comes from the country that uses migrant workers’ services. This study is needed to understand the root problems that have been faced by Indonesian Workers who working in the Middle East. This study aims to find out author’s world view Marruni, the character of Indonesian Migrant Worker in the Novel of Sumayyah by using the theory of genetic structuralism.

In rough terrains, such as landslides or volcanic eruptions, it is extremely complex to plan safe trajectories for an Unmanned Ground Vehicle (UGV), since both robot stability and path execution feasibility must be guaranteed. In this paper, we present a complete solution for the autonomous navigation of ground vehicles in the mentioned scenarios. The proposed solution integrates three different aspects. The first is the coverage path planning for the definition of UAV trajectories for aerial imagery acquisition. The collected images are used for the photogrammetric reconstruction of the considered area. The second aspect is the adoption of a flock of UAVs to implement the coverage in a parallel way. In fact, when non-coverable zones are present, decomposition of the whole area to survey is performed. A solution to assign the different regions among the flying vehicles composing the team is presented. The last aspect is the path planning of the ground vehicle by means of a traversability analysis performed on the terrain 3D model. The computed paths are optimal in terms of the difficulty of moving across the rough terrain. The results of each step within the overall approach are shown.

This article considers the development of a system to enable the in-flight-launch of one aerial system by another. The article discusses how an optimal release mechanism was developed taking into account the aerodynamics of one specific mothership and child Unmanned Aerial Vehicle (UAV). Furthermore, it discusses the PID-based control concept that was introduced in order to autonomously stabilise the child UAV after being released from the mothership UAV. Finally, the article demonstrates how the concept of a mothership and child UAV combination could be taken advantage of in the context of a search and rescue operation.
