Authors: Karandaeva Olga I. , Yakimov Ivan A. , Filimonova Alexandra A. , Gartlib Ekaterina A. , Yachikov Igor M.
Published: December 2019

The article is dedicated to research of the technical state of a furnace transformer. The study was conducted on the basis of statistical processing of continuously measured parameters of partial discharges (PD). The authors characterize the causes of PD occurrence and their impact on the insulation condition. The article provides information on the on-line monitoring system applied at high-voltage transformers of superpowered arc steel-melting furnaces and ladle furnaces at metallurgical plants. The system implements (among other methods) the method of diagnosing the insulation state by means of mathematical processing of PD parameters. Continuously measured values are apparent charge and the parameter called partial discharge intensity (PDI) characterizing the power and intensity of PD. The authors studied the parameter trends and conducted the statistical processing of the measurements results. In addition, the authors give the rationale for the application of the parameter “reciprocal stochastic connection force” between the PD amplitude and PDI as a generalized criterion of the insulation state and failure localization. The article compares trends of power and PD amplitude at various transformer technical states (before and after unscheduled repair). The authors confirm the possibility to diagnose emerging defects by comparing the correlation factors of these dependences. An example of defect occurrence and its location is provided. As a result, the authors manage to prove the efficiency of the proposed method of analysis of the high-voltage transformer state. This research has produced an integrated approach that enables on-the-go technical diagnosis, fault localization, and accident prevention. The key product of this research is a transformer diagnosis method based on processing the data of online PD monitoring. To that end, the proposed method uses statistical toolkits available for a PC. The areas for further prospective research are outlined. The authors also give recommendations on a more extensive application of the developed method.

Authors: Alegre Pablo , Barrera Joaquín , Carriazo Alfonso
Published: December 2019

The Maslov form is a closed form for a Lagrangian submanifold of C m , and it is a conformal form if and only if M satisfies the equality case of a natural inequality between the norm of the mean curvature and the scalar curvature, and it happens if and only if the second fundamental form satisfies a certain relation. In a previous paper we presented a natural inequality between the norm of the mean curvature and the scalar curvature of slant submanifolds of generalized Sasakian space forms, characterizing the equality case by certain expression of the second fundamental form. In this paper, first, we present an adapted form for slant submanifolds of a generalized Sasakian space form, similar to the Maslov form, that is always closed. And, in the equality case, we studied under which circumstances the given closed form is also conformal.
On the Use of Functionally Graded Materials to Differentiate the Effects of Surface Severe Plastic Deformation, Roughness and Chemical Composition on Cell Proliferation

Published: December 2019

Additive manufacturing allows the manufacture of parts made of functionally graded materials (FGM) with a chemical gradient. This research work underlines that the use of FGM makes it possible to study mechanical, microstructural or biological characteristics while minimizing the number of required samples. The application of severe plastic deformation (SPD) by surface mechanical attrition treatment (SMAT) on FGM brings new insights on a major question in this field: which is the most important parameter between roughness, chemistry and microstructure modification on biocompatibility? Our study demonstrates that roughness has a large impact on adhesion while microstructure refinement plays a key role during the early stage of proliferation. After several days, chemistry is the main parameter that holds sway in the proliferation stage. With this respect, we also show that niobium has a much better biocompatibility than molybdenum when alloyed with titanium.

Published: December 2019

Banana inflorescences are a byproduct of banana cultivation consumed in various regions of Brazil as a non-conventional food. This byproduct represents an alternative food supply that can contribute to the resolution of nutritional problems and hunger. This product is also used in Asia as a traditional remedy for the treatment of various illnesses such as bronchitis and dysentery. However, there is a lack of chemical and pharmacological data to support its consumption as a functional food. Therefore, this work aimed to study the anti-inflammatory action of Musa acuminata blossom by quantifying the cytokine levels (NOx, IL-1β, TNF-α, and IL-6) in peritoneal neutrophils, and to study its antiparasitic activities using the intracellular forms of T. cruzi, L. amazonensis, and L. infantum. This work also aimed to establish the chemical profile of the inflorescence using UPLC-ESI-MS analysis. Flowers and the crude bract extracts were partitioned in dichloromethane and n-butanol to afford four fractions (FDCM, FNBU, BDCM, and BNBU). FDCM showed moderate trypanocidal activity and promising anti-inflammatory properties by inhibiting IL-1β, TNF-α, and IL-6. BDCM significantly inhibited the secretion of TNF-α, while BNBU was active against IL-6 and NOx. LCMS data of these fractions revealed an unprecedented presence of arylpropanoid sucroses alongside flavonoids, triterpenes, benzofurans, stilbenes, and iridoids. The obtained results revealed that banana inflorescences could be used as an anti-inflammatory food ingredient to control inflammatory diseases.

Alkaloids having acetylcholinesterase (AChE) inhibitory activity are commonly found in traditional Chinese medicine (TCM); for example, berberine from Coptis chinensis, galantamine from Lycoris radiata, and huperzine A from Huperzia serrata. In practice of TCM, Stephaniae Tetrandrae Radix (STR) is often combined with Coptidis Rhizoma (CR) or Phellodendri Chinensis Cortex (PCC) as paired herbs during clinical application. Fangchinoline from STR and coptisine and/or berberine from CR and/or PCC are active alkaloids in inhibiting AChE. The traditional usage of paired herbs suggests the synergistic effect of fangchinoline–coptisine or fangchinoline–berberine pairing in AChE inhibition. HPLC was applied to identify the main components in herbal extracts of STR, CR, and PCC, and the AChE inhibition of their main components was determined by Ellman assay. The synergism of herb combination and active component combination was calculated by median-effect principle. Molecular docking was applied to investigate the underlying binding mechanisms of the active components with the AChE protein. It was found that fangchinoline showed AChE inhibitory potency; furthermore, fangchinoline–coptisine/berberine pairs (at ratios of 1:5, 1:2, 1:1, and 2:1) synergistically inhibited AChE; the combination index (CI) at different ratios was less than one when Fa = 0.5, suggesting synergistic inhibition of AChE. Furthermore, the molecular docking simulation supported this enzymatic inhibition. Therefore, fangchinoline–coptisine/berberine pairs, or their parental herbal mixtures, may potentially be developed as a possible therapeutic strategy for Alzheimer’s patients.

Published: December 2019

In this study, we determined the antimicrobial activity of ten essential oils (EOs)—oregano, thyme, clove, arborvitae, cassia, lemongrass, melaleuca, eucalyptus, lavender, and clary sage—against drug-resistant microorganisms previously isolated from patients with skin infections. The essential oil compositions were determined using gas chromatography coupled to mass spectrometry (GC/MS). The assayed bacteria included Pseudomonas aeruginosa, Proteus vulgaris, Citrobacter koseri, and Klebsiella pneumoniae. Two drug-resistant yeasts (Candida albicans and Candida parapsilosis) were also involved in our survey. Oregano, thyme, cassia, lemongrass and arborvitae showed very strong antibacterial and antifungal activity against all tested strains. These results show that these essential oils may be effective in preventing the growth of the drug-resistant microorganisms responsible for wound infections. In this study, the genotoxic effects of tested essential oils on healthy human keratinocytes HaCaT were evaluated using the comet assay for the first time. These results revealed that none of the essential oils induced significant DNA damage in vitro after 24 h. Moreover, the treatment of HaCaT cells with essential oils increased the total antioxidant status (TAS) level. The obtained results indicate that EOs could be used as a potential source of safe and potent natural antimicrobial and antioxidant agents in the pharmaceutical and food industries.

Published: December 2019

Sisymbrium officinale (L.) Scop., commonly known as “hedge mustard” or “the singer’s plant” is a wild plant common in Eurasian regions. Its cultivation is mainly dedicated to herboristic applications and it has only recently been introduced into Italy. The active botanicals in S. officinale are glucosinolates, generally estimated by using UV or high-performance liquid chromatography (HPLC). Using both techniques, we measured the total glucosinolates from S. officinale in different parts of the plant as roots, leaves, seeds, and flowers. A comparison was made for cultivated and wild samples, and for samples obtained with different pre-treatment and fresh, frozen, and dried storage conditions. Cultivated and wild plants have a comparable amount of total glucosinolates, while drying procedures can reduce the final glucosinolates content. The content in glucoputranjivin, which is the chemical marker for glucosinolates in S. officinale, has been determined using HPLC and a pure reference standard. Glucoputranjivin and two isothiocyanates from S. officinale have been submitted to in vitro assays with the platform of bitter taste receptors of the T2Rs family. The results show that glucoputranjivin is a selective agonist of receptor T2R16.

A Single-Turnover Kinetic Study of DNA Demethylation Catalyzed by Fe(II)/α-Ketoglutarate-Dependent Dioxygenase AlkB
Authors: Kanazhevskaya Lyubov Yu. , Alekseeva Irina V. , Fedorova Olga S.
Published: December 2019

AlkB is a Fe(II)/α-ketoglutarate-dependent dioxygenase that repairs some alkylated bases of DNA and RNA in Escherichia coli. In the course of catalysis, oxidation of a co-substrate (α-ketoglutarate, αKG) leads to the formation of a highly reactive ‘oxyferryl’ enzyme-bound intermediate, Fe(IV) = O, ensuring hydroxylation of the alkyl nucleobase adducts. Previous studies have revealed that AlkB is a flexible protein and can adopt different conformations during interactions with cofactors and DNA. To assess the conformational dynamics of the enzyme in complex with single- or double-stranded DNA in real-time mode, we employed the stopped-flow fluorescence method. N1-Methyladenine (m1A) introduced into a sequence of 15-mer oligonucleotides was chosen as the specific damage. Single-turnover kinetics were monitored by means of intrinsic fluorescence of the protein’s Trp residues, fluorescent base analogue 2-aminopurine (2aPu), and a dye–quencher pair (FAM/BHQ1). For all the fluorescent labels, the fluorescent traces showed several phases of consistent conformational changes, which were assigned to specific steps of the enzymatic process. These data offer an overall picture of the structural dynamics of AlkB and DNA during their interaction.

Published: December 2019

Lycium (also known as Goji berry) is used in traditional Chinese medicine (TCM) with claimed benefits, including eye and liver protection, immune system fortification and blood glucose control. The commercially available product comes from either the L. barbarum or L. chinense species, with the former dominating the marketplace due to its better taste profile. The main objective of this study was to develop a validated LC-ESI-MS/MS method to quantify multiple key bio-active analytes in commercially available Lycium berries and to qualitatively assess these samples using a principal component analysis (PCA). A LC-ESI-MS/MS method for the quantitation of seven analytes selected using the Herbal Chemical Marker Ranking System (Herb MaRS) was developed. The Herb MaRS ranking system considered bioavailability, bioactivity and physiological action of each target analyte, its intended use and the commercial availability of an analytical standard. After method optimization combining high resolving power with selective detection, seven analytes were quantified and the Lycium samples were quantitatively profiled. Chromatographic spectra were also obtained using longer run-time LC-UV and GC-MS methods in order to qualitatively assess the samples using a principal component analysis (PCA). The result of the method validation procedure was a 15.5 min LC-ESI-MS/MS method developed for the quantification of seven analytes in commercial Lycium samples. Wide variation in analyte concentration was observed with the following results (analyte range in mg/g): rutin, 16.1–49.2; narcissin, 0.37–1.65; nictoflorin, 0.26–0.78; coumaric acid, 6.84–12.2; scopoletin, 0.33–2.61; caffeic acid, 0.08–0.32; chlorogenic acid, 1.1–9.12. The quantitative results for the L. barbarum and L. chinense species samples indicate that they cannot be differentiated based on the bio-actives tested. A qualitative assessment using PCA generated from un-targeted LC-UV and GC-MS phytochemical spectra led to the same conclusion. The un-targeted quantitative and qualitative phytochemical profiling indicates that commercial L. barbarum and L. chinense cannot be distinguished using chemical analytical methods. Genetic fingerprinting and pharmacological testing may be needed to ensure the efficacy of commercial Lycium in order to validate label claims.

Measuring the foot plantar pressure has the potential to be an important tool in many areas such as enhancing sports performance, diagnosing diseases, and rehabilitation. In general, the plantar pressure sensor should have robustness, durability, and high repeatability, as it should measure the pressure due to body weight. Here, we present a novel insole foot plantar pressure sensor using a highly sensitive crack-based strain sensor. The sensor is made of elastomer, stainless steel, a crack-based sensor, and a 3D-printed frame. Insoles are made of elastomer with Shore A 40, which is used as part of the sensor, to distribute the load to the sensor. The 3D-printed frame and stainless steel prevent breakage of the crack-based sensor and enable elastic behavior. The sensor response is highly repeatable and shows excellent durability even after 20,000 cycles. We show that the insole pressure sensor can be used as a real-time monitoring system using the pressure visualization program.
An Improved SINS Alignment Method Based on Adaptive Cubature Kalman Filter
Authors: Zhang Yonggang , Xu Geng , Liu Xin
Published: December 2019

Initial alignment is critical and indispensable for the inertial navigation system (INS), which determines the initial attitude matrix between the reference navigation frame and the body frame. The conventional initial alignment methods based on the Kalman-like filter require an accurate noise covariance matrix of state and measurement to guarantee the high estimation accuracy. However, in a real-life practical environment, the uncertain noise covariance matrices are often induced by the motion of the carrier and external disturbance. To solve the problem of initial alignment with uncertain noise covariance matrices and a large initial misalignment angle in practical environment, an improved initial alignment method based on an adaptive cubature Kalman filter (ACKF) is proposed in this paper. By virtue of the idea of the variational Bayesian (VB) method, the system state, one step predicted error covariance matrix, and measurement noise covariance matrix of initial alignment are adaptively estimated together. Simulation and vehicle experiment results demonstrate that the proposed method can improve the accuracy of initial alignment compared with existing methods.

Published: December 2019

Compared to traditional coal mines, the mining-induced dynamic deformation of drilling solution mining activities may result in even more serious damage to surface buildings and infrastructures due to the different exploitation mode. Therefore, long-term dynamic monitoring and analysis of rock salt mines is extremely important for preventing potential geological damages. In this work, the small baseline subset Interferometric Synthetic Aperture Radar (SBAS-InSAR) technique with Sentinel−1A imagery is utilized to monitor the ground surface deformation of a rock salt mining area. The time-series analysis is carried out to obtain the spatial–temporal characteristics of land subsidence caused by drilling solution mining activities. A typical rock salt mine in Changde, China is selected as the test site. Twenty-four scenes of Sentinel−1A image data acquired from June 2015 to January 2017 are used to obtain the time-series subsidence of the test mine. The temporal–spatial evolution of the derived settlement funnels is revealed. The time-series deformation on typical feature points has been analyzed. Experimental results show that the obtained drilling solution mining-induced subsidence has a spatial characteristic of multiplied peaks along the transversal direction. Temporally, the large-scale surface settlement for the rock salt mine area begins to appear in September 2016, with a time lag of 8 months, and shows an obvious seasonal fluctuation. The maximum cumulative subsidence is detected up to 199 mm. These subsiding characteristics are consistent with the connected groove mining method used in drilling water solution mines. To evaluate the reliability of the results, the SBAS-derived results are compared with the field-leveling measurements. The estimated root mean square error (RMSE) of ±11 mm indicates a high consistency.
Delta-Sigma Modulated Visible Light Communication Illumination System Using a Projector with the Digital Micro-Mirror Device
Authors: Kodama Motoi , Haruyama Shinichiro
Published: December 2019

There is a unique transmission method of visible light communication (VLC) that can transmit multiple data in multiple directions simultaneously by using a projector with the digital micro-mirror device (DMD). Previously, we proposed a method of transmitting data from the projector that transmits digitally modulated VLC signal from each pixel, and in this paper, we propose an extension of the method to transmit audio signal by using a special type of modulation called delta-sigma-modulation (DSM). The DSM-VLC system employs a simple receiver that comprises simple analog electric circuits, which contribute to low power consumption. We made a DSM-VLC prototype and verified that the prototype was able to send four different waves to different directions. Additionally, the experiments’ results agree very well with the simulation results. Furthermore, we designed two types of DSM: pulse width modulation (PWM) and pulse density modulation (PDM), and we verified that the PDM-VLC is better than the PWM-VLC regarding the DMD switching frequency’s efficiency. Our proposed DSM-VLC can be used for such applications as voice information guidance systems with direction-selective messages.
Compressive Sensing for Tomographic Imaging of a Target with a Narrowband Bistatic Radar
Authors: Nguyen Ngoc Hung , Berry Paul , Tran Hai-Tan
Published: December 2019

This paper introduces a new approach to bistatic radar tomographic imaging based on the concept of compressive sensing and sparse reconstruction. The field of compressive sensing has established a mathematical framework which guarantees sparse solutions for under-determined linear inverse problems. In this paper, we present a new formulation for the bistatic radar tomography problem based on sparse inversion, moving away from the conventional k-space tomography approach. The proposed sparse inversion approach allows high-quality images of the target to be obtained from limited narrowband radar data. In particular, we exploit the use of the parameter-refined orthogonal matching pursuit (PROMP) algorithm to obtain a sparse solution for the sparse-based tomography formulation. A key important feature of the PROMP algorithm is that it is capable of tackling the dictionary mismatch problem arising from off-grid scatterers by perturbing the dictionary atoms and allowing them to go off the grid. Performance evaluation studies involving both simulated and real data are presented to demonstrate the performance advantage of the proposed sparsity-based tomography method over the conventional k-space tomography method.
On AUV Control with the Aid of Position Estimation Algorithms Based on Acoustic Seabed Sensing and DOA Measurements
Authors: Miller Alexander , Miller Boris , Miller Gregory
Published: December 2019

This article discusses various approaches to the control of autonomous underwater vehicles (AUVs) with the aid of different velocity-position estimation algorithms. Traditionally this field is considered as the area of the extended Kalman filter (EKF) application: It became a universal tool for nonlinear observation models and its use is ubiquitous. Meanwhile, the specific characteristics of underwater navigation, such as an incomplete sets of measurements, constraints on the range metering or even impossibility of range measurements, observations provided by rather specific acoustic beacons, sonar observations, and other features seriously narrow the applicability of common instruments due to a high level of uncertainty and nonlinearity. The AUV navigation system, not being able to rely on a single source of position estimation, has to take into account all available information. This leads to the necessity of various complex estimation and data fusion algorithms, which are the matter of the present article. Here we discuss some approaches to the AUV position estimation such as conditionally minimax nonlinear filtering (CMNF) and unbiased pseudo-measurement filters (UPMFs) in conjunction with velocity estimation based on the seabed profile acoustic sensing. The presented estimation algorithms serve as a basis for a locally optimal AUV motion control algorithm, which is also presented.
Towards Efficient Data Collection in Space-Based Internet of Things
Authors: Fei Changjiang , Zhao Baokang , Yu Wanrong , Wu Chunqing
Published: December 2019

Due to the strong anti-destructive ability, global coverage, and independent infrastructure of the space-based Internet of Things (S-IoT), it is one of the most important ways to achieve a real interconnection of all things. In S-IoT, a single satellite can often achieve thousands of kilometers of coverage and needs to provide data transmission services for massive ground nodes. However, satellite bandwidth is usually low and the uplink and downlink bandwidth is extremely asymmetric. Therefore, exact data collection is not affordable for S-IoT. In this paper, an approximate data collection algorithm is proposed for S-IoT; that is, the sampling-reconstruction (SR) algorithm. Since the uplink bandwidth is very limited, the SR algorithm samples only the sensory data of some nodes and then reconstructs the unacquired data based on the spatiotemporal correlation between the sensory data. In order to obtain higher data collection precision under a certain data collection ratio, the SR algorithm optimizes the sampling node selection by leveraging the curvature characteristics of the sensory data in time and space dimensions. Moreover, the SR algorithm innovatively applies spatiotemporal compressive sensing (ST-CS) technology to accurately reconstruct unacquired sensory data by making full use of the spatiotemporal correlation between the sensory data. We used a real-weather data set to evaluate the performance of the SR algorithm and compared it with two existing representative approximate data collection algorithms. The experimental results show that the SR algorithm is well-suited for S-IoT and can achieve efficient data collection under the condition that the uplink bandwidth is extremely limited.
Diverse Citizenship? Food Sovereignty and the Power of Acting Otherwise
Authors: Fladvad Benno
Published: December 2019

This contribution discusses two different but interlinked fields of research: political theories of sovereignty and citizenship, as well as conceptualizations of emerging alternative food movements. In drawing on James Tully’s practiced-based understanding of ‘diverse citizenship’, as well as on other selected theories of postmodern political thought, it focuses on the contested political nature of the food sovereignty movement, specifically with regard to the dynamics and actions that have brought it into being. In doing so, it conceives of citizenship as materializing on the basis of multi-faceted practices of ‘acting otherwise’, which stands in sharp contrast to a conceptualization of citizenship as an institutionalized status, as it is understood in the liberal tradition. In order to deepen and to sharpen this alternative approach, this contribution additionally draws on Theodore Schatzki’s practice theory, which, despite its rather apolitical character, makes it possible to conceive of political practices as emergent and situational phenomena that are closely connected to the quotidian practices of everyday life. The combination of these perspectives bears great potential for theoretical discussions on alternative food movements as well as for their empirical investigation, since it puts emphasis on the way how practitioners and advocates for food sovereignty disclose themselves in multifaceted struggles over the imposition and the challenging of the rules of social living together.
Uniform Parallel Machine Scheduling with Dedicated Machines, Job Splitting and Setup Resources
Authors: Lee Jun-Ho , Jang Hoon
Published: December 2019

We examine a uniform parallel machine scheduling problem with dedicated machines, job splitting, and limited setup resources for makespan minimization. In this problem, machines have different processing speeds, and each job can only be processed at several designated machines. A job can be split into multiple sections and those sections can be processed on multiple machines simultaneously. Sequence-independent setup times are assumed, and setup operations between jobs require setup operators that are limited. For the problem, we first develop a mathematical optimization model and for large-sized problems a constructive heuristic algorithm is proposed. Finally, we show that the algorithm developed is efficient and provides good solutions by experiments with various scenarios.
What Is Missing in Food Loss and Waste Analyses? A Close Look at Fruit and Vegetable Wholesale Markets
Authors: Zhang Ren Jie , Lee Brian , Chang Hung-Hao
Published: December 2019

Food loss and waste (FLW) has been the subject of significant research, with recent empirical evidence analyzing the determinants of FLW in many different countries. Much of this literature examines FLW at the farm, food processing, and consumer level. However, to the best of our knowledge, no study thus far has addressed this issue at food wholesale markets. This paper fills this knowledge gap by examining food loss at fruit and vegetable wholesale markets. Using a dataset with individual auction transactions from Taiwan, we examine the extent to which average daily market prices, product quality, and disaster shocks are associated with food loss. Results point to a negative effect of daily market prices on food loss. Furthermore, disaster shocks can lead to greater food loss, particularly typhoons. These effects are heterogeneous across the distribution for the weight of food loss.
How to Improve the Total Cost of Ownership of Electric Vehicles: An Analysis of the Light Commercial Vehicle Segment
Authors: Lebeau Philippe , Macharis Cathy , Van Mierlo Joeri
Published: December 2019

This paper analyses how the total cost of ownership (TCO) of electric light commercial vehicles change with the number of kilometers driven, the period of ownership, the residual value of the battery, and different fiscal incentives, as well as a kilometer charging scheme. This paper demonstrates that a kilometer-based charge and reduced fiscal incentives for conventional vans can drastically improve the TCO of electric commercial light duty vehicles. Second life applications for batteries could also have a strong impact on the TCO of electric vans as they could retrieve a better residual value. Finally, the paper shows that the TCO of electric vans can be optimized based on its usage. These are important findings given the ambitious objective of carbon free city logistics by 2030. Adoption of electric vans remains very low and this paper offers an up to date analysis to stimulate the electrification of light commercial vehicles, a segment that is growing fast in city logistics.

Entre esses fatores, destacamos a história de vida dos atores envolvidos no processo, visando a antever como a implementação das novas diretrizes se enuncia para, a partir disso, pensar estratégias de ajuste da política. Considerações finais: Diante disso, recomendamos a construção de espaços para que um número possível de coordenadores construa narrativas acerca de suas histórias de vida.

Objetivo: compreender as percepções e práticas dos técnicos de Enfermagem acerca da Visita Domiciliar enquanto ferramenta de cuidado na Estratégia Saúde da Família. Metodologia: pesquisa qualitativa, realizada em Unidades de Saúde da Família, com 14 técnicos de Enfermagem de um município da Zona da Mata Mineira. Os dados foram analisados conforme a técnica de Análise de Conteúdo. Resultados: os depoimentos permitiram a emersão de três categorias: “Significados e sentidos para a realização da Visita Domiciliar”; “A Visita Domiciliar no processo de trabalho do Técnico de Enfermagem” e “Desafios e potencialidades na prática da Visita Domiciliar”. Considerações finais: os técnicos ainda percebem e realizam a Visita Domiciliar como uma ação pontual e curativista, direcionada, principalmente, a doenças já diagnosticadas. Emerge a necessidade de reorganização da formação e do processo de trabalho desta categoria profissional, de modo a valorizar a Visita Domiciliar como uma ferramenta de cuidado integral do técnico de Enfermagem na Atenção Primária.

Fotografia, corpo e política:
Authors: Monteiro Charles
Published: December 2019

O presente artigo visa analisar o ensaio fotográfico À la recherche de l ‘eu-dourado de Pedro Vasquez publicado em foto-livro pela editora francesa Contrejour em 1976. O ensaio está inserido no contexto sócio-político e cultural mais amplo dos anos 1970. De um lado, a obra faz uma crítica às estruturas de poder e dominação que limitam e submetem o corpo numa sociedade de consumo marcada pela racionalidade técnica e burocrática. Por outro, a obra está relacionada à promoção da fotografia como linguagem no campo das artes visuais no contexto de criação de instituições, galerias, festivais e editoras especializadas em fotografia.
“Requebrando os quadris”:
Authors: Carloni Karla
Published: December 2019

Este artigo tem por objetivo avaliar como durante a década de 1920 locais destinados à prática de danças sociais na cidade do Rio de Janeiro se transformaram em espaços de transgressão feminina. A hipótese central é de que as mulheres pertencentes às camadas médias da sociedade se apropriaram de danças executadas ao som do jazz e desenvolveram um novo léxico corporal que questionava os padrões de comportamento em um momento de transformações sociais e políticas. O gênero musical e suas danças representavam a cultura diaspórica negra e o cosmopolitismo das principais capitais ocidentais. As revistas ilustradas contêm discursos conservadores que tentavam controlar “o sexo frágil” e revelam como as jovens ao som das “músicas modernas” tomaram o espaço público buscando se libertar do controle masculino.

Uma primeira aproximação comparada ao fascismo feminino no Brasil e na Espanha, 1932-1937
Authors: Morant i Ariño Toni
Published: December 2019

O presente texto busca ser uma colaboração ao incipiente campo de estudos comparados sobre os fascismos brasileiro e espanhol e ampliá-lo, ainda, por meio dos estudos de gênero. Configurase como a primeira análise comparativa entre as integralistas e as falangistas, e também entre as fascistas brasileiras e as de qualquer país da Europa do período entreguerras. Não é em vão que apenas um olhar comparado permite estabelecer semelhanças e diferenças, padrões transnacionais e especificidades nacionais neste universo fascista
O Poder Judiciário na Primeira República:
Authors: Conde Sá Pinto Surama , De Souza Castro Tatiana
Published: December 2019

Este artigo analisa o papel do Judiciário brasileiro na Primeira República. Na base documental, utilizamos habeas corpus originários do Distrito Federal, protocolados no STF, nos anos 1920, que estão disponíveis no Arquivo do Supremo Tribunal Federal (STF), em Brasília, e no Arquivo Nacional, na cidade do Rio de Janeiro. Do ponto de vista metodológico, lançamos mão da amostragem; foram catalogados 20% dos processos protocolados no início de cada ano. Conforme será demonstrado, apesar da facilidade de ser solicitado, o instituto do habeas corpus esteve longe de ser um remédio, de fato, concedido à população na Primeira República, pois sua concessão era bastan te restrita. O principal argumento aqui defendido é o da necessidade de relativização das interpretações que supervalorizam o papel do STF e do Judiciário no exercício da cidadania no período. Tais enunciados projetam para o período em questão o papel desempenhado pelo STF na democracia brasileira da Nova República, momento em que esses estudos são produzidos, e superdimensionam a atuação do Poder Judiciário para combater o modelo de uma cidadania reativa, construída a partir das análises divulgadas nos anos 1980.

El objetivo buscado es no solo tener un panorama actual sobre la situación de los profesores en la universidad sino, además, conocer las características de los nuevos horizontes laborales, como así también identificar los problemas y las oportunidades. El análisis se llevó a cabo sobre la población docente de las tres instituciones que otorgan el título de Profesorado en Bibliotecología en Argentina: la Universidad de Buenos Aires, la Universidad Nacional de La Plata y la Universidad Nacional de Mar del Plata. Como resultado se advirtieron un conjunto de características compartidas por los docentes de las tres universidades, lo que evidencia la existencia de un perfil común.

Resumen

Este artículo explora el establecimiento de bibliotecas en los asentamientos judíos de las provincias de Chaco, Santiago del Estero, Río Negro y La Pampa, que se produjo cuando los judíos emigraron de Europa oriental en 1889. Los principales temas que se tratan son el desarrollo de las bibliotecas como centros educativos y sociales en los cuales los colonos encontraron un espacio para interactuar después de una larga jornada de trabajo en los campos; cómo se establecieron estas bibliotecas, y el apoyo y los fondos que se les proporcionaron. La migración a las ciudades por parte de los hijos de los primeros pobladores acarreó la desaparición de estas bibliotecas, la reubicación de su material y la desaparición de la mayoría de los archivos que podrían contarnos sus historias. A través de las memorias de los colonos, leemos acerca de las dificultades que tuvieron que enfrentar y las alegrías que lograron disfrutar durante el difícil período de adaptación al suelo argentino.
