Amino Acid Transporters in Plant Cells: A Brief Review
Authors: Yang Guangzhe , Wei Qiuxing , Huang Hao , Xia Jixing
Published: July 2020

Amino acids are not only a nitrogen source that can be directly absorbed by plants, but also the major transport form of organic nitrogen in plants. A large number of amino acid transporters have been identified in different plant species. Despite belonging to different families, these amino acid transporters usually exhibit some general features, such as broad expression pattern and substrate selectivity. This review mainly focuses on transporters involved in amino acid uptake, phloem loading and unloading, xylem-phloem transfer, import into seed and intracellular transport in plants. We summarize the other physiological roles mediated by amino acid transporters, including development regulation, abiotic stress tolerance and defense response. Finally, we discuss the potential applications of amino acid transporters for crop genetic improvement.
Main Challenges and Actions Needed to Improve Conservation and Sustainable Use of Our Crop Wild Relatives
Authors: Engels Johannes M. M. , Thormann Imke
Published: July 2020

Crop wild relatives (CWR, plural CWRs) are those wild species that are regarded as the ancestors of our cultivated crops. It was only at the end of the last century that they were accorded a high priority for their conservation and, thus, for many genebanks, they are a new and somewhat unknown set of plant genetic resources for food and agriculture. After defining and characterizing CWR and their general threat status, providing an assessment of biological peculiarities of CWR with respect to conservation management, illustrating the need for prioritization and addressing the importance of data and information, we made a detailed assessment of specific aspects of CWRs of direct relevance for their conservation and use. This assessment was complemented by an overview of the current status of CWRs conservation and use, including facts and figures on the in situ conservation, on the ex situ conservation in genebanks and botanic gardens, as well as of the advantages of a combination of in situ and ex situ conservation, the so-called complementary conservation approach. In addition, a brief assessment of the situation with respect to the use of CWRs was made. From these assessments we derived the needs for action in order to achieve a more effective and efficient conservation and use, specifically with respect to the documentation of CWRs, their in situ and ex situ, as well as their complementarity conservation, and how synergies between these components can be obtained. The review was concluded with suggestions on how use can be strengthened, as well as the conservation system at large at the local, national, and regional/international level. Finally, based on the foregoing assessments, a number of recommendations were elaborated on how CWRs can be better conserved and used in order to exploit their potential benefits more effectively.
Techno-Economic Evaluation of Biorefineries Based on Low-Value Feedstocks Using the BioSTEAM Software: A Case Study for Animal Bedding
Authors: Sanchis-Sebastiá Miguel , Gomis-Fons Joaquín , Galbe Mats , Wallberg Ola
Published: July 2020

Biofuels are still too costly to compete in the energy market and it has been suggested that low-value feedstocks could provide an opportunity for the production of low-cost biofuels; however, the lower quality of these feedstocks requires the introduction of a conditioning step in the biorefinery process. The aim of this study was to evaluate whether feedstock savings cover the cost of conditioning in the case of animal bedding. The BioSTEAM software was used to simulate a wheat straw biorefinery and an animal bedding biorefinery, whose economic performance was compared. The wheat straw biorefinery could deliver ethanol at a minimum selling price of USD 0.61 per liter, which is similar to prices in the literature. The cost of producing ethanol in the animal bedding biorefinery without water recycling was almost 40% higher, increasing the minimum selling price to USD 1.1 per liter of ethanol. After introducing water recycling in the conditioning step, the animal bedding biorefinery could deliver ethanol at a minimum selling price of USD 0.38 per liter, which is 40% lower than in the case of the wheat straw biorefinery. This demonstrates that low-value feedstocks can be used to reduce the biofuel price, as feedstock savings easily cover the additional conditioning cost.
Human Occupancy Detection via Passive Cognitive Radio

Published: July 2020

Human occupancy detection (HOD) in an enclosed space, such as indoors or inside of a vehicle, via passive cognitive radio (CR) is a new and challenging research area. Part of the difficulty arises from the fact that a human subject cannot easily be detected due to spectrum variation. In this paper, we present an advanced HOD system that dynamically reconfigures a CR to collect passive radio frequency (RF) signals at different places of interest. Principal component analysis (PCA) and recursive feature elimination with logistic regression (RFE-LR) algorithms are applied to find the frequency bands sensitive to human occupancy when the baseline spectrum changes with locations. With the dynamically collected passive RF signals, four machine learning (ML) classifiers are applied to detect human occupancy, including support vector machine (SVM), k-nearest neighbors (KNN), decision tree (DT), and linear SVM with stochastic gradient descent (SGD) training. The experimental results show that the proposed system can accurately detect human subjects—not only in residential rooms—but also in commercial vehicles, demonstrating that passive CR is a viable technique for HOD. More specifically, the RFE-LR with SGD achieves the best results with a limited number of frequency bands. The proposed adaptive spectrum sensing method has not only enabled robust detection performance in various environments, but also improved the efficiency of the CR system in terms of speed and power consumption.
Correntropy-Induced Discriminative Nonnegative Sparse Coding for Robust Palmprint Recognition
Authors: Jing Kunlei , Zhang Xinman , Song Guokun
Published: July 2020

Palmprint recognition has been widely studied for security applications. However, there is a lack of in-depth investigations on robust palmprint recognition. Regression analysis being intuitively interpretable on robustness design inspires us to propose a correntropy-induced discriminative nonnegative sparse coding method for robust palmprint recognition. Specifically, we combine the correntropy metric and l1-norm to present a powerful error estimator that gains flexibility and robustness to various contaminations by cooperatively detecting and correcting errors. Furthermore, we equip the error estimator with a tailored discriminative nonnegative sparse regularizer to extract significant nonnegative features. We manage to explore an analytical optimization approach regarding this unified scheme and figure out a novel efficient method to address the challenging non-negative constraint. Finally, the proposed coding method is extended for robust multispectral palmprint recognition. Namely, we develop a constrained particle swarm optimizer to search for the feasible parameters to fuse the extracted robust features of different spectrums. Extensive experimental results on both contactless and contact-based multispectral palmprint databases verify the flexibility and robustness of our methods.
Point-of-Care Diagnostics in Coagulation Management

Published: July 2020

This review provides a comprehensive and up-to-date overview of point-of-care (POC) devices most commonly used for coagulation analyses in the acute settings. Fast and reliable assessment of hemostasis is essential for the management of trauma and other bleeding patients. Routine coagulation assays are not designed to visualize the process of clot formation, and their results are obtained only after 30–90 m due to the requirements of sample preparation and the analytical process. POC devices such as viscoelastic coagulation tests, platelet function tests, blood gas analysis and other coagulometers provide new options for the assessment of hemostasis, and are important tools for an individualized, goal-directed, and factor-based substitution therapy. We give a detailed overview of the related tests, their characteristics and clinical implications. This review emphasizes the evident advantages of the speed and predictive power of POC clot measurement in the context of a goal-directed and algorithm-based therapy to improve the patient’s outcome. Interpretation of viscoelastic tests is facilitated by a new visualization technology.
Path Planner for Autonomous Exploration of Underground Mines by Aerial Vehicles
Authors: Rubio-Sierra Carlos , Domínguez Diego , Gonzalo Jesús , Escapa Alberto
Published: July 2020

This paper presents a path planner solution that makes it possible to autonomously explore underground mines with aerial robots (typically multicopters). In these environments the operations may be limited by many factors like the lack of external navigation signals, the narrow passages and the absence of radio communications. The designed path planner is defined as a simple and highly computationally efficient algorithm that, only relying on a laser imaging detection and ranging (LIDAR) sensor with Simultaneous localization and mapping (SLAM) capability, permits the exploration of a set of single-level mining tunnels. It performs dynamic planning based on exploration vectors, a novel variant of the open sector method with reinforced filtering. The algorithm incorporates global awareness and obstacle avoidance modules. The first one prevents the possibility of getting trapped in a loop, whereas the second one facilitates the navigation along narrow tunnels. The performance of the proposed solution has been tested in different study cases with a Hardware-in-the-loop (HIL) simulator developed for this purpose. In all situations the path planner logic performed as expected and the used routing was optimal. Furthermore, the path efficiency, measured in terms of traveled distance and used time, was high when compared with an ideal reference case. The result is a very fast, real-time, and static memory capable algorithm, which implemented on the proposed architecture presents a feasible solution for the autonomous exploration of underground mines.

Published: July 2020

We estimate precipitable water vapor (PWV) from data collected by the low-cost Global Navigation Satellite System (GNSS) receiver at a vessel. The dual-frequency GNSS receiver that the vessel ISABU is equipped with that is operated by the Korea Institute of Ocean Science and Technology. The ISABU served in the Pacific Ocean for scientific research during a period from August 30 to September 21, 2018. It also performs radiosonde observations to obtain a vertical profile of troposphere on the vessel’s path. The GNSS-derived PWV is compared to radiosonde observations and the Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite output. A bias and root-mean-square (RMS) error between shipborne GNSS-PWV and radiosonde-PWV were −1.48 and 5.22 mm, respectively. When compared to the ground GNSS-PWV, shipborne GNSS-PWV has a relatively large RMS error in comparison with radiosonde-PWV. However, the GNSS observations on the vessel are still in good agreement with radiosonde observations. On the other hand, the GNSS-PWV is not well linearly correlated with AIRS-PWV. The RMS error between the two observations was approximately 8.97 mm. In addition, we showed that the vessel on the sea surface has significantly larger carrier phase multipath error compared to the ground-based GNSS observations. This also can result in reducing the accuracy of shipborne GNSS-PWV. However, we suggest that the shipborne GNSS has sufficient potential to derive PWV with the kinematic precise point positioning (PPP) solution on the vessel.
Field Network—A New Method to Detect Directional Object
Authors: Liu Jin , Gao Yongjian
Published: July 2020

As the development of object detection technology in computer vision, identifying objects is always an active yet challenging task, and even more efficient and accurate requirements are being imposed on state-of-the-art algorithms. However, many algorithms perform object box regression based on RPN(Region Proposal Network) and anchors, which cannot accurately describe the shape information of the object. In this paper, we propose a new object detection method called Field Network (FN) and Region Fitting Algorithm (RFA). It can solve these problems by Center Field. Center field reflects the probability of the pixel approaching the object center. Different from the previous methods, we abandoned anchors and ROI technologies, and propose the concept of Field. Field is the intensity of the object area, reflecting the probability of the object in the area. Based on the distribution of the probability density of the object center in the visual field perception area, we add the Object Field in the output part. And we abstract it into an Elliptic Field with normal distribution and use RFA to fit objects. Additionally, we add two fields to predict the x,y components of the object direction which contain the neural units in the field array. We extract the objects through these Fields. Moreover, our model is relatively simple and have smaller size, which is only 73 M. Our method improves performance considerably over baseline systems on DOTA, MS COCO and PASCAL VOC datasets, with overall performance competitive with recent state-of-the-art systems.

Published: July 2020

Laser-induced graphene (LIG) has the advantages of one-step fabrication, prominent mechanical performance, as well as high conductivity; it acts as the ideal material to fabricate flexible strain sensors. In this study, a wearable flexible strain sensor consisting of three-dimensional (3D) wavy LIG and silicone rubber was reported. With a laser to scan on a polyimide film, 3D wavy LIG could be synthesized on the wavy surface of a mold. The wavy-LIG strain sensor was developed by transferring LIG to silicone rubber substrate and then packaging. For stress concentration, the ultimate strain primarily took place in the troughs of wavy LIG, resulting in higher sensitivity and less damage to LIG during stretching. As a result, the wavy-LIG strain sensor achieved high sensitivity (gauge factor was 37.8 in a range from 0% to 31.8%, better than the planar-LIG sensor), low hysteresis (1.39%) and wide working range (from 0% to 47.7%). The wavy-LIG strain sensor had a stable and rapid dynamic response; its reversibility and repeatability were demonstrated. After 5000 cycles, the signal peak varied by only 2.32%, demonstrating the long-term durability. Besides, its applications in detecting facial skin expansion, muscle movement, and joint movement, were discussed. It is considered a simple, efficient, and low-cost method to fabricate a flexible strain sensor with high sensitivity and structural robustness. Furthermore, the wavy-LIG strain senor can be developed into wearable sensing devices for virtual/augmented reality or electronic skin.

Published: July 2020

Longitudinal research on training and dietary practices of natural powerlifters is limited. This study investigated the effect of phases of training on physical and physiological parameters in male natural powerlifters. Nine participants completed testing at two time points: (i) preparatory phase (~3 months prior to a major competition) and (ii) competition phase (1–2 weeks from a major competition). No significant changes between training phases were found for muscle strength and power. A trend for significance was found for decreased muscle endurance of the lower body (−24.4%, p = 0.08). A significant increase in leg lean mass was found at the competition phase (2.3%, p = 0.04), although no changes for other body composition measures were observed. No change was observed for any health marker except a trend for increased urinary creatinine clearance at the competition phase (12.5%, p = 0.08). A significant reduction in training volume for the lower body (−75.0%, p = 0.04) and a trend for a decrease in total energy intake (−17.0%, p = 0.06) was observed during the competition phase. Despite modifications in training and dietary practices, it appears that muscle performance, body composition, and health status remain relatively stable between training phases in male natural powerlifters.
Synchrotron Radiation in Periodic Magnetic Fields of FEL Undulators—Theoretical Analysis for Experiments
Authors: Zhukovsky Konstantin
Published: July 2020

A theoretical study of the synchrotron radiation (SR) from electrons in periodic magnetic fields with non-periodic magnetic components is presented. It is applied to several free electron lasers (FELs) accounting for the real characteristics of their electron beams: finite sizes, energy spread, divergence etc. All the losses and off-axis effects are accounted analytically. Exact expressions for the harmonic radiation in multiperiodic magnetic fields with non-periodic components and off-axis effects are given in terms of the generalized Bessel and Airy-type functions. Their analytical forms clearly distinguish all contributions in each polarization of the undulator radiation (UR). The application to FELs is demonstrated with the help of the analytical model for FEL harmonic power evolution, which accounts for all major losses and has been verified with the results of well documented FEL experiments. The analysis of the off-axis effects for the odd and even harmonics is performed for SPRING8 Angstrom Compact free-electron LAser (SACLA) and Pohang Accelerator Laboratory (PAL-XFEL). The modelling describes theoretically the power levels of odd and even harmonics and the spectral line width and shape. The obtained theoretical results agree well with the available data for FEL experiments; where no data exist, we predict and explain the FEL radiation properties. The proposed theoretical approach is applicable to practically any FEL.
A Spacetime Symmetry Approach to Relativistic Quantum Multi-Particle Entanglement
Authors: Ungar Abraham A.
Published: July 2020

A Lorentz transformation group SO(m, n) of signature (m, n), m, n ∈ N, in m time and n space dimensions, is the group of pseudo-rotations of a pseudo-Euclidean space of signature (m, n). Accordingly, the Lorentz group SO(1, 3) is the common Lorentz transformation group from which special relativity theory stems. It is widely acknowledged that special relativity and quantum theories are at odds. In particular, it is known that entangled particles involve Lorentz symmetry violation. We, therefore, review studies that led to the discovery that the Lorentz group SO(m, n) forms the symmetry group by which a multi-particle system of m entangled n-dimensional particles can be understood in an extended sense of relativistic settings. Consequently, we enrich special relativity by incorporating the Lorentz transformation groups of signature (m, 3) for all m ≥ 2. The resulting enriched special relativity provides the common symmetry group SO(1, 3) of the (1 + 3)-dimensional spacetime of individual particles, along with the symmetry group SO(m, 3) of the (m + 3)-dimensional spacetime of multi-particle systems of m entangled 3-dimensional particles, for all m ≥ 2. A unified parametrization of the Lorentz groups SO(m, n) for all m, n ∈ N, shakes down the underlying matrix algebra into elegant and transparent results. The special case when (m, n) = (1, 3) is supported experimentally by special relativity. It is hoped that this review article will stimulate the search for experimental support when (m, n) = (m, 3) for all m ≥ 2.
In Vivo Evaluation of the Chronic Oral Toxicity of the Marine Toxin Palytoxin

Published: July 2020

Palytoxin (PLTX) is one of the most poisonous substances known to date and considered as an emergent toxin in Europe. Palytoxin binds to the Na+-K+ ATPase, converting the enzyme in a permeant cation channel. This toxin is known for causing human fatal intoxications associated with the consumption of contaminated fish and crustaceans such as crabs, groupers, mackerel, and parrotfish. Human intoxications by PLTX after consumption of contaminated fishery products are a serious health issue and can be fatal. Different reports have previously explored the acute oral toxicity of PLTX in mice. Although the presence of palytoxin in marine products is currently not regulated in Europe, the European Food Safety Authority expressed its opinion on PLTX and demanded assessment for chronic toxicity studies of this potent marine toxin. In this study, the chronic toxicity of palytoxin was evaluated after oral administration to mice by gavage during a 28-day period. After chronic exposure of mice to the toxin, a lethal dose 50 (LD50) of 0.44 µg/kg of PLTX and a No-Observed-Adverse-Effect Level (NOAEL) of 0.03 µg/kg for repeated daily oral administration of PLTX were determined. These results indicate a much higher chronic toxicity of PLTX and a lower NOAEL than that previously described in shorter treatment periods, pointing out the need to further reevaluate the levels of this compound in marine products.
Critical Tidal Currents in General Relativity
Authors: Mashhoon Bahram
Published: July 2020

Relativistic tidal equations are formulated with respect to the rest frame of a central gravitational source and their solutions are studied. The existence of certain relativistic critical tidal currents are thereby elucidated. Specifically, observers that are spatially at rest in the exterior Kerr spacetime are considered in detail; in effect, these fiducial observers define the rest frame of the Kerr source. The general tidal equations for the free motion of test particles are worked out with respect to the Kerr background. The analytic solutions of these equations are investigated and the existence of a tidal acceleration mechanism is emphasized.

Authors: Andreto Lucas
Published: July 2020

O presente artigo busca evidenciar as diferenças entre o conceito de “aristocracia operária” em Vladimir Lênin e em Eric Hobsbawm com o objetivo de debater a tese levantada pelo autor E. Gualberto a respeito dos trabalhadores gráficos brasileiros na década de 20 e 30. Gualberto, fundamentado em Hobsbawm e Lênin defende que os gráficos não constituíam uma “aristocracia operária”. De nossa parte, buscamos mostrar que sob o ponto de vista de Hobsbawm, os gráficos constituíam uma “aristocracia operária” e, justamente por isso, tinham condições de desempenhar um papel de vanguarda no movimento operário brasileiro.
GÊNEROS E SEXUALIDADES DIVERGENTES: ESCOLA E DINÂMICAS DE SUBALTERNIZAÇÃO DA DIFERENÇA
Authors: Sales Romualdo , Machado Charliton
Published: July 2020

Este artigo tem como objetivo apresentar questões para reflexão sobre como os mecanismos de controle atuam sobre a construção das identidades sociais e sua diversidade, levando em consideração aspectos de gênero e sexualidade. Nossa abordagem dialoga com o trabalho de Foucault, particularmente em relação aos conceitos de aparelho de sexualidade, biopoder e seu gerenciamento. Esses conceitos ajudam a pensar sobre a prática, nas escolas, de técnicas de controle e subordinação contra pessoas que não realizam o roteiro descrito como performatividade binária de gênero e sexualidade. Nesse contexto, apresentamos alguns resultados de uma pesquisa de nossa dissertação de mestrado intitulada: "A diferença vai para a escola: problematizando articulações discursivas e epistemológicas sobre marcadores sociais das diferenças das pessoas no espaço educacional", apresentado em 2019 pelo PPGS-UFPB. Trata-se de uma pesquisa de campo realizada em uma escola pública localizada no município de Remígio, no interior da Paraíba. Em termos metodológicos, esta pesquisa foi desenvolvida por meio de uma abordagem etnográfica, realizada por meio de observação direta e entrevistas com professores e diretores. É importante enfatizar que, nesta escola, a manifestação das diferenças de gênero e sexualidade das pessoas é interpretada por meio de concepções de regime de inteligibilidade binária construídas por discursos normalizadores. Portanto, dentro desse espaço escolar, indivíduos que quebram o desempenho binário de gênero são tratados como subordinados e punidos com retaliação.

No dia 8 de maio de 2019, motoristas que trabalham nas principais empresas de transporte particular por aplicativo Uber, Cabify, 99 e Lyft realizaram um movimento paredista global por melhores condições de trabalho. Fizemos uma pesquisa na manifestação que ocorreu na cidade de São Paulo, realizando entrevista com os trabalhadores, trabalhadoras, sindicalistas e lideranças do movimento presentes, com o objetivo de conhecer as suas reivindicações e, através delas, aprofundar o debate sobre as condições de trabalho ofertadas pelas empresas de transporte particular por aplicativo e, não obstante, atentarmo-nos para as estratégias e dificuldades de articulação e organização dessa fração da classe trabalhadora, sendo este artigo uma apresentação dos resultados destas entrevistas. A partir dos dados levantados, concluímos que não há uma relação de parceria entre as empresas e os motoristas, na qual se estabelece uma relação capital versus trabalho, com intensa exploração da força de trabalho. A greve global, e tantas outras que eclodem no setor, evidenciam e legitimam a antagônica e conflituosa relação entre motoristas e empresas-aplicativo, sendo que as novas tecnologias da informação e comunicação proporcionando um salto de qualidade na capacidade de controle da empresa sobre os trabalhadores e, ao mesmo tempo, colaborando para novas formas de organização de ações coletivas.
Por um estruturalismo dos afetos
Authors: Franco de Paula Tiago
Published: July 2020

O presente trabalho é um ensaio crítico à posição ontológica das Ciências Sociais. Tendo como ponto de partida as dificuldades que os estudos na área têm encontrado em explicar os fenômenos atuais, busca apresentar uma chave teórica pouco utilizada pelos cientistas sociais: os afetos. Os afetos, comumente ignorados no campo pela acusação de serem questões subjetivistas, representam uma variável fundamental para se pensar a ação social. A inserção dessa variável é feita por meio da filosofia de Espinosa, base para a elaboração teórica de um Estruturalismo dos Afetos. Tal concepção traz uma crítica do sujeito racional autônomo e questiona a percepção da sociedade como um conjunto de normas valorativas e sociais. Segundo ela, tanto os indivíduos quanto as instituições sociais são um circuito de afetos, não estruturas racionais e normativas. Sem nenhuma pretensão definitiva, o artigo é uma breve sistematização das premissas e conclusões iniciais de um Estruturalismo dos Afetos. Mais do que isso, busca ser uma crítica inicial aos estudos sociais que não fazem uso de chaves-teóricas de outros campos e se prendem às concepções dominantes das Ciências Sociais.

Efficacy and Safety of Vitamin D3 (Cholecalciferol) Oral Solution Compared to Tablet and Capsule: A Randomized, Parallel-Design, Active-Controlled Study
Authors: M. Nandgaye Krishnakumar , B. Kadam Santoshi , J. Palkar Dr. Prashant
Published: July 2020

We performed a study to compare the efficacy of Vitamin D3 oral solution with a conventional tablets and capsules in hypovitaminosis D patients. One hundred eighty subjects were divided into three different groups and received vitamin D3 60000 IU per week for eight weeks either in the form of an oral solution or a tablet or a capsule. A significant increase in serum 25(OH)D was observed in vitamin D3 oral solution from baseline (P=0.0001) as compared to a tablet(P=0.0001) and capsule (P=0.0001). A significant decrease in iPTH levels was seen in the vitamin D3 oral solution group from baseline (P=0.0001) and also as compared to a tablet(P=0.0001) and capsule (P=0.0001). Oral solution of vitamin D3 is a nanotechnology-based formulation which was found to be effective and safe. Thus, treatment with vitamin D3 oral solution in hypovitaminosis D patients may result in faster and higher improvement in the normalization of vitamin D levels.

Bu deneyimi yaşayan kişi ise kendini işine adamakta ve işinden haz almaktadır. Bu da iş doyumu ile sonuçlanarak, örgüt verimliliğine pozitif katkı sağlamaktadır. Diğer taraftan mevcut çalışma aynı zamanda, işte yaşanan akış deneyimi, işle bütünleşme ve iş doyumu arasındaki ilişkinin belirlenmesine yönelik bir model de önermektedir. 259 turizm çalışanı ile birlikte araştırma modeli test edilmiştir. Araştırma örneklemini, Kuşadası’nda faaliyet gösteren 4 ve 5 yıldızlı konaklama işletmeleri çalışanları oluşturmaktadır. Araştırmanın analiz sürecinde, SPSS veri analiz programı ile frekans analizi, güvenirlik analizi, açımlayıcı (keşfedici) faktör analizi, LISREL programı ile de doğrulayıcı faktör analizi yapılmıştır. Araştırma sonuçlarına göre, çalışanların içsel motivasyon, haz ve sarmalanma alt boyutlarıyla işte akış deneyimi gerçekleşmekte, bu da işle bütünleşmeyi ve işle bütünleşme de iş doyumunu anlamlı ve pozitif yönde etkilemektedir. Çalışmanın bazı sınırlılıkları bulunmaktadır. İşle bütünleşmenin bu çalışma kapsamında, Schaufeli ve Bakker (2003) tarafından geliştirilen UWES ölçeğinin kısa versiyonu ile ölçülmüş olmasıdır. Yine, bütünleşme ve sarmalanma kavramlarının ayrı yapılar olup olmadığı, sarmalanmanın boyut mu sonuç mu olduğu, odaklanılmış dikkat ile sarmalanma kavramlarının farklı yapılar olup olmadığı da araştırılması gereken konulardır. Tüm bu bulgular, ilgili literatür kapsamında değerlendirilip tartışılmış ve buradan yola çıkılarak, gelecek çalışmalar için önerilerde bulunulmuştur.
Institutional Maintenance of E-Commerce through Traditional Retail
Authors: TOPAL Çağrı , GEYİK Bahtiyar Onur
Published: July 2020

This
study analyzes the process of opening traditional, physical retail stores by
e-commerce companies as institutional work of maintenance. Past research examines
internal mechanisms used to maintain institutions and ignores the question of
how an external, alternative institution can contribute to the maintenance of
another institution. This study shows that traditional retail as a relatively
old institution helps maintain e-commerce as a relatively new institution through
eight different mechanisms at four levels including customers, employees,
suppliers, and companies themselves. For customers, traditional stores help
concretize e-commerce companies and personalize customer experience. For
employees, they create new tasks and responsibilities and increase their
involvement in both strategic and daily decisions. For suppliers, they develop
trust by making e-commerce companies a concrete entity to do business with and
promote visibility by expanding sales channels and the product range. Lastly,
for companies themselves, they increase brand awareness and result in growth
through additional marketing and sales opportunities. Traditional retail thus strengthens
the position of e-commerce companies in the market by facilitating better
relations with their customers, employees, and suppliers as well as directly
contributes to the company image and growth.

Agricultura urbana e migrações
Authors: Oliveira Luana do Carmo Araujo de , Alves Cristiana Guimarães , Dala Paula Bruno Martins
Published: July 2020

Neste artigo, promove-se uma reflexão sobre o papel da agricultura urbana (AU) no uso e ocupação do espaço urbano e sua conexão com os processos migratórios. A AU é uma prática com multifuncionalidades, uma vez que integra aspectos ecológicos, sociais, culturais e políticos para o desenvolvimento de cidades economicamente justas, ecologicamente sustentáveis e culturalmente sensíveis. No entanto, o que se pretende neste texto é visibilizar os aspectos sociopolíticos, bem como simbólicos e culturais da AU, ou seja, discutir seu caráter promotor de direitos e coesão social, nos processos de vínculo comunitário, na expressão de práticas tradicionais, em resistência às imposições do modelo de vida ditado pelo sistema socioeconômico dominante, visando à valorização da identidade cultural e das novas territorialidades em experiências de migrações.
Vozes de Tchernóbil

Published: July 2020

A resenha analisa criticamente o livro Vozes de Tchernóbil, da jornalista Svetlana Aleksiévitch. A obra é construída com base em pesquisa de história oral com os sobreviventes do acidente nuclear ocorrido na Ucrânia em 1986, e promove reflexões acerca do acontecimento. Descreve o comportamento da população, do governo, dos envolvidos, de forma a desencadear conjecturas, para além das denúncias contidas no texto, sobre os caminhos que devem ser observados doravante no que se refere à geração de energia como necessidade social. Ou seja, como produzi-la na atualidade? O texto oferece margem para fazer uma separação entre as falhas humanas, a falta de informação e as lesões aos cidadãos e a geração de energia nuclear, fazendo-nos concluir que a diligência das ações e o respeito ao Estado de Direito seriam um promissor recomeço.
O setor de energia elétrica brasileiro e a perspectiva de uma reforma setorial
Authors: Nogueira Ana Carolina Miranda Lima , Bertussi Geovana Lorena
Published: July 2020

Desde o governo Fernando Henrique Cardoso, a relação público-privado do setor de energia elétrica nunca saiu totalmente das discussões do Planalto. A MP 579/2012 e a privatização das distribuidoras da Eletrobras foram marcos que, aliados a um governo herdeiro de instabilidade política, fizeram ganhar força uma pauta mais liberal. A expansão do mercado livre de energia acessível a todos os consumidores brasileiros tem ganhado mais adeptos, e os principais afetados por essa possível mudança são os consumidores residenciais. Por isso, este estudo, explorando a história do setor, visa apresentar possíveis vantagens da expansão do mercado livre de energia elétrica, assim como suas consequências. Como será garantida a segurança energética? O consumidor está pronto para lidar com um mercado livre de energia? Os benefícios de um mercado competitivo são possíveis em um país de grande dimensão como o Brasil?
Crystalloids versus colloids versus hypertonic saline co-load during spinal anesthesia: which is more effective?
Authors: Shaker Ehab H. , El Sabeeny Walaa Y.
Published: July 2020

Spinal anesthesia is very commonly accompanied by hypotension due to sympathetic blockade, which leads to vasodilation. There is an ongoing debate concerning pre-load versus co-load and also the best suitable type of fluid to be given, including hypertonic saline (HS). We conducted this study to compare the efficacy of the three solutions, crystalloids vs. colloids vs. hypertonic saline co-load during spinal anesthesia.

Authors: Vasudevarao Sunil Baikadi , Raja Kurinchi , Rao Rammoorthi
Published: July 2020

Background & objective: We studied the safety and effectiveness of combination of dexmedetomidine and fentanyl for chronic sub-dural hematoma (CSDH) evacuation. Main objectives of the study was to register the effects on the combination on the cardio-respiratory and analgesic outcome.

Methodology: 56 patients with CSDH were divided into two group. Patients of Group A received dexmedetomidine 1 µg/kg over a period of 10 min with fentanyl 1 µg/kg, followed by an infusion of dexmedetomidine 0.3 µg/kg/min. Group B received fentanyl 1 µg/kg and midazolam 0.03 mg/kg IV. Sedation scores, hemodynamic changes and serial arterial blood gas (ABG) measurements were compared between the two groups.

Results: Heart rate and diastolic blood pressure were significantly lower in Group A compared to Group B throughout the observation period after premedication. Systolic blood pressure readings was significantly lower in Group A compared to Group B from 10 min onwards till the end. ABG analysis showed that Group A had significantly lower PCO2 levels during and at the end of surgery and significantly higher PO2 at the end of procedure.

Conclusion: The use of dexmedetomidine is associated with significantly higher PO2 at the end of the surgical procedure. It results in lower heart rate, systolic and diastolic blood pressures and PCO2 levels during and at the end of the subdural hematoma evacuation, but the fall remains within the physiological range.
Current role of imaging in the management of children with Wilms tumor according to the new umbrella protocol
Authors: Varchetta Giovanni , Tanzillo Paolina , Mei Sara
Published: July 2020

Wilms tumor is the most common primary renal tumor in childhood. Children with Wilms tumor typically present with an asymptomatic abdominal mass, usually detected on a routine medical checkup or discovered coincidentally by parents. The initial differential diagnosis is with extrarenal abdominal masses; once a tumor of renal origin is established, distinguishing between Wilms tumor and other primary renal neoplasms such as congenital mesoblastic nephroma, clear cell sarcoma, malignant rhabdoid tumor and renal cell carcinoma may not be easy. However, in many cases imaging findings in conjunction with the patient's clinical and epidemiological data, allow the diagnosis of Wilms tumor. Wilms tumor care offers one of the most striking examples of success of pediatric oncology. Over the last decades the European SIOP studies have been the key to developing standardized diagnostic procedures, improved risk stratification, and adjusted treatment recommendations for children with Wilms tumor and this has resulted rate of overall survival is currently greater than 90%. As in previous SIOP trials and studies, the new protocol for the diagnosis and treatment of childhood renal tumors, the UMBRELLA SIOP–RTSG 2016, mandates preoperative chemotherapy without preceding mandatory histological assessment. Therefore, imaging studies are essential to obtain a presumptive diagnosis of WT, to provide disease staging information and to measure the tumor volume after neoadjuvant chemotherapy for the purposes of postoperative treatment stratification. This review describes role of imaging in the management of children with Wilms tumor, according to the current recommendations of the UMBRELLA protocol.
