Preterm birth (PTB), defined as parturition prior to 37 weeks of gestation, is the leading cause of morbidity and mortality in the neonatal population. The incidence and severity of complications of prematurity increase with decreasing gestational age and birthweight. The aim of this review study is to select the most current evidence on the role of oxidative stress in the onset of preterm complication prevention strategies and treatment options with pre-clinical and clinical trials. We also provide a literature review of primary and secondary studies on the role of oxidative stress in preterm infants and its eventual treatment in prematurity diseases. We conducted a systematic literature search of the Medline (Pubmed), Scholar, and ClinicalTrials.gov databases, retroactively, over a 7-year period. From an initial 777 articles identified, 25 articles were identified that met the inclusion and exclusion criteria. Of these, there were 11 literature reviews: one prospective cohort study, one experimental study, three case-control studies, three pre-clinical trials, and six clinical trials. Several biomarkers were identified as particularly promising, such as the products of the peroxidation of polyunsaturated fatty acids, those of the oxidation of phenylalanine, and the hydroxyl radicals that can attack the DNA chain. Among the most promising drugs, there are those for the prevention of neurological damage, such as melatonin, retinoid lactoferrin, and vitamin E. The microbiome also has an important role in oxidative stress. In conclusion, the most recent studies show that a strong relationship between oxidative stress and prematurity exists and that, unfortunately, there is still little therapeutic evidence reported in the literature.

Calendulae flos is a valued plant material with known anti-inflammatory and antimicrobiological properties. The limitation for its use in the treatment of chronic wounds is the lack of adhesion to the required site of action. Obtaining the Calendulae flos lyophilized extract from water-ethanolic extract allowed to prepare valuable material whose biological activity in the wound healing process was confirmed by a positive result of the scratch test. The Calendulae flos lyophilized extract was standardized for the contents of the chlorogenic acid and the narcissin. The significant potency of the Calendulae flos pharmacological activity has become the reason for studies on its novel applications in combination with the multifunctional chitosan carrier, to create a new, valuable solution in the treatment of chronic wounds. The use of chitosan as a carrier allowed for the controlled release of the chlorogenic acid and the narcissin. These substances, characterized by prolonged release from the chitosan delivery system, were identified as well permeable, based on the results of the studies of the parallel artificial membrane permeability assay (PAMPA Skin) a model simulating permeability through membrane skin. The combination of the Calendulae flos lyophilized extract and the chitosan allowed for synergy of action towards hyaluronidase inhibition and effective microbiological activity. Optimization of the hypromellose hydrogel preparation ensuring the required rheological properties necessary for the release of the chlorogenic acid and the narcissin from the chitosan delivery system, as well as demonstrated antimicrobial activity allows indicating formulations of 3% Calendulae flos lyophilized extract with chitosan 80/500 in weight ratio 1:1 and 2% or 3% hypromellose as an important support with high compliance of response and effectiveness for patients suffering from chronic wounds.

The aim of this work was to synthesize carboxymethyl cellulose (CMC) and produce CMC films from the cellulose of palm bunch and bagasse agricultural waste. The effect of various amounts of H2O2 (0–40% v/v) during delignification on the properties of cellulose, CMC, and CMC films was studied. As the H2O2 content increased, yield and the lignin content of the cellulose from palm bunch and bagasse decreased, whereas lightness (L*) and whiteness index (WI) increased. FTIR confirmed the substitution of a carboxymethyl group on the cellulose structure. A higher degree of substitution of CMC from both sources was found when 20%–30% H2O2 was employed. The trend in the L* and WI values of each CMC and CMC film was related to those values in their respective cellulose. Bleaching each cellulose with 20% H2O2 provided the cellulose with the highest viscosity and the CMC films with the greatest mechanical (higher tensile strength and elongation at break) and soluble attributes, but the lowest water vapor barrier. This evidence indicates that cellulose delignification with H2O2 has a strong effect on the appearance and physical properties of both CMCs.

Published: July 2020

In this study, polyvinylidene fluoride (PVDF)-graphene oxide (GO) membranes were obtained by employing triethyl phosphate (TEP) as a solvent. GO nanosheets were prepared and characterized in terms of scanning and transmission electron microscopy (SEM and TEM, respectively), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), chemical analysis and inductively coupled plasma mass spectroscopy (ICP). Two different phase inversion techniques, Non-Solvent Induced Phase Separation (NIPS) and Vapour-Induced Phase Separation (VIPS)/NIPS, were applied to study the effect of fabrication procedure on the membrane structure and properties. Membranes were characterized by SEM, AFM, pore size, porosity, contact angle and mechanical tests, and finally tested for photocatalytic methylene blue (MB+) degradation under visible light irradiation. The effect of different pH values of dye aqueous solutions on the photocatalytic efficiency was investigated. Finally, the influence of NaCl salt on the MB+ photodegradation process was also evaluated.

Published: July 2020

Unsupervised machine learning algorithms (clustering, genetic, and principal component analysis) automate Unmanned Aerial Vehicle (UAV) missions as well as the creation and refinement of iterative 3D photogrammetric models with a next best view (NBV) approach. The novel approach uses Structure-from-Motion (SfM) to achieve convergence to a specified orthomosaic resolution by identifying edges in the point cloud and planning cameras that “view” the holes identified by edges without requiring an initial model. This iterative UAV photogrammetric method successfully runs in various Microsoft AirSim environments. Simulated ground sampling distance (GSD) of models reaches as low as 3.4 cm per pixel, and generally, successive iterations improve resolution. Besides analogous application in simulated environments, a field study of a retired municipal water tank illustrates the practical application and advantages of automated UAV iterative inspection of infrastructure using 63 % fewer photographs than a comparable manual flight with analogous density point clouds obtaining a GSD of less than 3 cm per pixel. Each iteration qualitatively increases resolution according to a logarithmic regression, reduces holes in models, and adds details to model edges.

Published: July 2020

In this paper, we present a Remote Sens. approach to localize parking cars in a city in order to enable the development of parking space availability models. We propose to use high-resolution stereo satellite images for this problem, as they provide enough details to make individual cars recognizable and the time interval between the stereo shots allows to reason about the moving or static condition of a car. Consequently, we describe a complete processing pipeline where raw satellite images are georeferenced, ortho-rectified, equipped with a digital surface model and an inclusion layer generated from Open Street Model vector data, and finally analyzed for parking cars by means of an adapted Faster R-CNN oriented bounding box detector. As a test site for the proposed approach, a new publicly available dataset of the city of Barcelona labeled with parking cars is presented. On this dataset, a Faster R-CNN model directly trained on the two ortho-rectified stereo images achieves an average precision of 0.65 for parking car detection. Finally, an extensive empirical and analytical evaluation shows the validity of our idea, as parking space occupancy can be broadly derived in fully visible areas, whereas moving cars are efficiently ruled out. Our evaluation also includes an in-depth analysis of the stereo occlusion problem in view of our application scenario as well as the suitability of using a reconstructed Digital Surface Model (DSM) as additional data modality for car detection. While an additional adoption of the DSM in our pipeline does not provide a beneficial cue for the detection task, the stereo images provide essentially two views of the dynamic scene at different timestamps. Therefore, for future studies, we recommend a satellite image acquisition geometry with smaller incidence angles, to decrease occlusions by buildings and thus improve the results with respect to completeness.
Detecting and Tracking Criminals in the Real World through an IoT-Based System
Authors: Tundis Andrea , Kaleem Humayun , Mühlhäuser Max
Published: July 2020

Criminals and related illegal activities represent problems that are neither trivial to predict nor easy to handle once they are identified. The Police Forces (PFs) typically base their strategies solely on their intra-communication, by neglecting the involvement of third parties, such as the citizens, in the investigation chain which results in a lack of timeliness among the occurrence of the criminal event, its identification, and intervention. In this regard, a system based on IoT social devices, for supporting the detection and tracking of criminals in the real world, is proposed. It aims to enable the communication and collaboration between citizens and PFs in the criminal investigation process by combining app-based technologies and embracing the advantages of an Edge-based architecture in terms of responsiveness, energy saving, local data computation, and distribution, along with information sharing. The proposed model as well as the algorithms, defined on the top of it, have been evaluated through a simulator for showing the logic of the system functioning, whereas the functionality of the app was assessed through a user study conducted upon a group of 30 users. Finally, the additional advantage in terms of intervention time was compared to statistical results.

Published: July 2020

Tactile sensors have been widely used and researched in various fields of medical and industrial applications. Gradually, they will be used as new input devices and contact sensors for interactive robots. If a tactile sensor is to be applied to various forms of human–machine interactions, it needs to be soft to ensure comfort and safety, and it should be easily customizable and inexpensive. The purpose of this study is to estimate 3D contact position of a novel image-based areal soft tactile sensor (IASTS) using printed array markers and multiple cameras. First, we introduce the hardware structure of the prototype IASTS, which consists of a soft material with printed array markers and multiple cameras with LEDs. Second, an estimation algorithm for the contact position is proposed based on the image processing of the array markers and their Gaussian fittings. A series of basic experiments was conducted and their results were analyzed to verify the effectiveness of the proposed IASTS hardware and its estimation software. To ensure the stability of the estimated contact positions a Kalman filter was developed. Finally, it was shown that the contact positions on the IASTS were estimated with a reasonable error value for soft haptic applications.

Published: July 2020

Biomechanical studies of winter sports are challenging due to environmental conditions which cannot be mimicked in a laboratory. In this study, a methodological approach was developed merging 2D video recordings with sensor-based motion capture to investigate ski jump landings. A reference measurement was carried out in a laboratory, and subsequently, the method was exemplified in a field study by assessing the effect of a ski boot modification on landing kinematics. Landings of four expert skiers were filmed under field conditions in the jump plane, and full body kinematics were measured with an inertial motion unit (IMU) -based motion capture suit. This exemplary study revealed that the combination of video and IMU data is viable. However, only one skier was able to make use of the added boot flexibility, likely due to an extended training time with the modified boot. In this case, maximum knee flexion changed by 36° and maximum ankle flexion by 13°, whereas the other three skiers changed only marginally. The results confirm that 2D video merged with IMU data are suitable for jump analyses in winter sports, and that the modified boot will allow for alterations in landing technique provided that enough time for training is given.
Climate Change Accounting and Reporting: A Systematic Literature Review
Authors: Gulluscio Carmela , Puntillo Pina , Luciani Valerio , Huisingh Donald
Published: July 2020

During the last few years, sustainability has become an increasingly important dimension for corporations. Many stakeholders expect companies to implement sustainability-oriented practices and report on these actions and their results. As a consequence, corporate accountability and, more specifically, corporate accounting and reporting, should focus not only on financial, social, and environmental performance, but also on sustainability-related aspects. Among these aspects, climate change is becoming increasingly important for companies, which must take action to counter the effects of their activities on climate change and inform their stakeholders about these actions and their effects. Given the initial state of research about climate change accounting and reporting, the authors focused on the sustainable development goal (SDG) no. 13, “climate action”, in order to highlight the current state and the future directions of this area of inquiry. They used a mixed approach to perform a systematic literature review about sustainability accounting/reporting and climate change: (1) a qualitative analysis according to a qualitative analytical framework, and (2) a bibliometric (descriptive statistical) approach. The authors found that: (1) the main perspectives addressed in the selected articles relate to sustainability accounting and reporting in a broad sense; (2) there was a lack of contributions about management of climate change-related aspects, with specific reference to strategic and operational planning, accounting, and control of the actions implemented by the management of firms to counter climate change problems. The authors suggested the topics accounting scholars should focus their future research upon and underscored the social responsibilities of accounting scholars to increasingly integrate climate change mitigation into their accounting foci. They reviewed the main areas of climate change accounting/reporting literature and identified the gaps to be filled.

Published: July 2020

The Sustainable Urban Mobility Planning (SUMP) process deals with barriers to improve accessibility and quality of life in urban mobility. Public opinion is highly essential for this process because it presents the real needs of road users. This paper illustrates the influence of public opinion on using Private Mobility Vehicle (PMV) in urban. A survey was carried out with 400 participants in Palermo, Italy. The results suggested that there was heterogeneity in gender and age groups in subcategories which represented people who use, do not use, and completely reject, using PMVs in urban. In addition, it was explored that there was a statistically significant relationship at 95% confidence level between sociodemographic characteristics (gender and age groups) and public opinion on PMV using. Employment status was found as an important parameter in transport planning. It was also showed that there was an inconsistency between local and national results. The results suggested that sociodemographic characteristics and public opinion should be investigated in further studies. In addition, a participatory planning process should be carried out to monitor for reliable evaluation in urban transport planning.
Potential Role for Consumers to Reduce Canadian Agricultural GHG Emissions by Diversifying Animal Protein Sources
Authors: Dyer James A. , Desjardins Raymond L. , Worth Devon E. , Vergé Xavier P.C.
Published: July 2020

The discussion of diversified protein sources triggered by the 2019 Canadian Food Guide has implications for Canada’s livestock industry. In response to this discussion, a scenario analysis is conducted on the potential impact of reducing red meat consumption on the greenhouse gas (GHG) emissions from Canadian livestock production. This analysis uses medical recommendations as a proxy for healthy servings of red meat. For simplicity, it was assumed that red meat is either beef or pork and that broilers are the only nonred meat choice. The medical scenario is combined with four livestock production scenarios for these three livestock types. Broiler consumption is allowed to expand to maintain national protein intake in all four scenarios. Under the medical scenario, red meat consumption in Canada would decrease from 2.5 Mt to 1.9 Mt of live weight. A feedlot diet for slaughter cattle, and a 50:50 split of the medically recommended red meat intake of beef and pork (Scenario 1), reduced GHG emissions by 3.9 Mt CO2e from the 20.6 Mt CO2e (carbon dioxide equivalent) for current consumption. Replacing the feedlot beef diet by grass fed beef (Scenario 2) increased GHG emissions by 1.5 Mt CO2e over Scenario 1. Halving the consumption of grass fed beef and increasing pork by 50% (Scenario 3) reduced GHG by 7.7 Mt CO2e. Reverting back to the feedlot diet, and the same 25:75 beef–pork ratio (Scenario 4), increased the GHG emissions reduction to 8.9 Mt CO2e. Without including the emission savings from the medical scenario, GHG reductions from Scenarios 3 and 4 dropped to 3.8 Mt and 5.0 Mt CO2e, respectively. No scenario exceeded the feed grain area required to meet the 2017 consumption of these commodities, but Scenario 2 required more forage area compared to consumption in 2017.
Mathematical Simulation of Forest Fire Impact on Industrial Facilities and Wood-Based Buildings
Authors: Baranovskiy Nikolay , Malinin Aleksey
Published: July 2020

The present work is devoted to the theoretical study of heat transfer in the enclosing structures of a wooden building exposed to the front of a forest fire. In the general case, the following effects could be distinguished: The direct effect of a forest fire flame, the effect of convective and radiant heat flux, and the removal of firebrands from the front of a forest fire. In this paper, only building enclosures were considered to be exposed to radiant heat flux from the front of a forest fire. The scenarios of the impacts of low- and high-intensity surface forest fires and crown forest fires were considered, taking into account the parameterized structure of the fire front, as well as various cladding materials and the time of the forest fire. As a result of mathematical modeling, temperature distributions over the surface and thickness of the cladding material were obtained, and ignition conditions were determined based on experimental data. The proposed simplified mathematical model and the obtained results can be used in the practice of protecting industrial facilities or rural settlements from forest fires. Particular attention should be paid to the potential use of the results in the Information System for Remote Monitoring of Forest Fires, ISDM-Rosleskhoz, in conjunction with geo-information technologies and methods of remote monitoring.

Authors: Lyu Weixia , Zheng Yanan , Fonseca Camila , Zhao Jerry Zhirong
Published: July 2020

Recent years have witnessed a rapid development of Public-Private Partnerships (PPP) as a new model of public service provision. Transitioning from bureaucrat- to market-oriented management of public services entails organizational changes that may affect employee satisfaction, and thus, PPP performance. We take sanitation services in H-City as a case study to explore the managerial factors that influenced worker satisfaction during the PPP transformation. Our research shows that motivation and transition factors influence worker satisfaction in the PPP transformation and may allow a smoother transformation of sanitation services. In particular, focusing on balancing workload and compensation, training, improving public attitudes, and adopting worker-friendly rules contribute to the satisfaction of sanitation workers. These findings will contribute to the transformation of the provision of public services in China.
Regenerative—The New Sustainable?
Authors: Gibbons Leah V.
Published: July 2020

Over time, sustainability paradigms have evolved from meeting human needs throughout time to improving human wellbeing and the viability of ecological systems. Regenerative sustainability (RS), the next wave of sustainability, includes and transcends these goals, aiming for thriving living systems in which whole-system health and wellbeing increase continually. A key difference between sustainability paradigms is the thinking underlying them, with regenerative sustainability based on a holistic worldview and paradigm, integrating recent understandings from science and practice, different ways of knowing, and inner and outer dimensions of sustainability necessary for systemic transformation. RS, practiced through regenerative development and design for over 50 years, aligns human consciousness and actions with living systems principles. When this alignment occurs, sustainable development goals are elevated to become regenerative development goals, with living systems principles and characteristics guiding the development of regenerative indicators and strategies made specific to a place through transformational co-creative processes. We should aim for regenerative sustainability because it offers holistic approaches based on how thriving living systems function, addresses the root causes of (un)sustainability, and is inherently more inspiring and motivational. Advancing regenerative sustainability will require fundamental shifts supported by more awareness and education, theoretical and practical development, leadership, empowering communities, and integrating spirituality.

A wide energy range including the Z boson peak and higher energies relevant for future e + e − colliders was covered. Sensitivity of observable asymmetries to the electroweak mixing angle and fermion weak coupling was discussed.
Holographic Projection of Electromagnetic Maxwell Theory
Authors: Bertolini Erica , Maggiore Nicola
Published: July 2020

The 4D Maxwell theory with single-sided planar boundary is considered. As a consequence of the presence of the boundary, two broken Ward identities are recovered, which, on-shell, give rise to two conserved currents living on the edge. A Kaç-Moody algebra formed by a subset of the bulk fields is obtained with central charge proportional to the inverse of the Maxwell coupling constant, and the degrees of freedom of the boundary theory are identified as two vector fields, also suggesting that the 3D theory should be a gauge theory. Finally the holographic contact between bulk and boundary theory is reached in two inequivalent ways, both leading to a unique 3D action describing a new gauge theory of two coupled vector fields with a topological Chern-Simons term with massive coefficient. In order to check that the 3D projection of 4D Maxwell theory is well defined, we computed the energy-momentum tensor and the propagators. The role of discrete symmetries is briefly discussed.
Recycling Waste Electrical and Electronic Equipment (WEEE) and the Management of Its Toxic Substances in Taiwan—A Case Study
Authors: Tsai Wen-Tien
Published: July 2020

In the past two decades, the waste electrical and electronic equipment (WEEE) management has become an important environmental issue internationally because it contained hazardous substances like heavy metals and brominated flame retardants. Moreover, some valuable substances were used in the electrical and electronic products, thus representing a circular industry for recycling of WEEE. Therefore, the Taiwan government formulated a legal WEEE recycling system since 1998 in response to the international trends of sustainable waste management and extended producer responsibility (EPR). This article adopted the national statistics in Taiwan regarding the online reporting amounts of collected WEEE since it has been officially designated as one of the mandatory recyclable wastes. Furthermore, the regulatory measures were addressed to update the status and subsidiary fee rates of WEEE recycling in Taiwan. In addition, this article also put emphasis on the regulations governing the toxic chemical substances contained in the WEEE. It showed that the average annual recycling amounts of home electronic appliances, information technology products and lighting in Taiwan during the 2017–2018 were around 117,000, 18,000 and 4500 metric tons, respectively. It was also indicated that the current WEEE recycling market in Taiwan has become saturated, reflecting the regulatory promulgation and promotional measures successfully. In response to the Stockholm Convention on persistent organic pollutants (POPs) and the Minamata Convention on Mercury, the Taiwan government declared some brominated flame retardants and heavy metals (i.e., mercury and cadmium) as a “toxic chemical substance” under the Toxic and Concerned Chemical Substance Control Act (TCCSCA), which shall be prohibited to use in the preparation of electrical and electronic equipment (EEE) since 1 January 2016. Through the central governing authority, local governments, and private recyclers in Taiwan, the successful WEEE recycling system not only reduce the pressure on sanitary disposal systems, but also prevent the chemical hazards from solid waste incineration systems. More significantly, the WEEE recycling in Taiwan echoed the United Nations (UN) Agenda 2030 for sustainable development goals.

Rainwater harvesting (RWH) for domestic uses is widely regarded as an economic and ecological solution in water conservation and storm management programs. This paper aims at evaluating long-term trends in 20-day cumulative rainfall periods per year in Poland, for assessing its impact on the design and operation conditions for RWH systems and resource availability. The time-series employed corresponds to a set of 50-year long time-series of rainfall (from 1970 to 2019) recorded at 19 synoptic meteorological stations scattered across Poland, one of the European countries with the lowest water availability index. The methods employed for assessing trends were the Mann–Kendall test (M–K) and the Sen’s slope estimator. Most of the datasets exhibit stationary behaviour during the 50-year long period, however, statistically significant downward trends were detected for precipitations in Wrocław and Opole. The findings of this study are valuable assets for integrated water management and sustainable planning in Poland.
Analysis of the Sealing Mechanism of Cement-Sodium Silicate Grout in Rock Fractures with Flowing Water
Authors: Zhu Guangxuan , Zhang Qingsong , Lin Xin , Liu Rentai , Zhang Lianzhen , Zhang Jianwei
Published: July 2020

The diffusion and sealing mechanisms of cement-sodium silicate grout (C-S grout), which is widely used in flowing water sealing projects, are complicated. Based on a large-scale quasi-three-dimensional simulation test platform of fracture dynamic water grouting, an orthogonal experiment of flowing-water sealing of C-S grout was performed. The grout was shown to diffuse in the form of an asymmetric ellipse. The flowing-water sealing process consists of three stages: (1) the grout diffuses to the fracture boundary in an asymmetrical ellipse; (2) the solidified body of grout develops; (3) the stable solidified body forms. The sealing efficiency was evaluated and graded by the reduction of water drainage through the fracture after grouting. Based on the test data, the factors that affect sealing efficiency can be listed in the following order from strong to weak: grout gel time, flowing water velocity, grout take, fracture plane width, and fracture aperture. Finally, a fitting equation was acquired to provide a reference for practical engineering applications.

Introduction: Pediatric community-acquired pneumonia incidence is rising both in the Russian Federation and around the world. Our objective was to establish the main features of the long-term epidemic process of community-acquired pneumonia in the Khanty-Mansi Autonomous Okrug – Yugra (KMAO) in 2014–2018. Materials and methods: We used official statistics of Rospotrebnadzor and results of a retrospective analysis of medical histories of 652 hospitalized children with clinical manifestations of community-acquired pneumonia for 2014–2018. Results: The long-term incidence rate of community-acquired pneumonia in the general population of KMAO for 2014–2018 was 449.2 ± 5.45 per 100,000 or 1.19 times higher than the corresponding Russian rate. The same rate among children under the age of 17 across administrative units of KMAO ranged from 821.4 ± 87.2 to 1,983.2 ± 69.2 per 100,000 for the same period. The long-term average incidence rate of community-acquired pneumonia in children under the age of 17 in KMAO in 2014-2018 was 684.4 ± 13.1 per 100,000 or 1.7 times higher than corresponding federal rate and 1.85 times higher than that in the regional adult population. Among the children hospitalized with community-acquired pneumonia in 2014–2018, the majority were toddlers aged 1-2 (37 %) while the percentages of infants of 0-1 and adolescents of 15–17 were the lowest and equaled 14% and 5%, respectively. As for etiology, we observed a decrease in bacterial community-acquired pneumonia, with a rise in 2018, and an increasing incidence of mycoplasma pneumoniea pneumonia. Conclusions: In 2014–2018, the epidemic process of community-acquired pneumonia in KMAO was characterized by a common trend of significant growth in the general population with the highest rate of increase registered in 2018. Among the hospitalized pediatric cases of pneumonia, the majority were children of 1 to 6 (63%). Redistribution of the spectrum of bacterial pathogens of pneumonia in children was characterized by a decrease in pneumococcal infection and a higher detection rate of mycoplasma infection.

Homo-morphic systems present a novel way to encrypt data, via which operations performed on the encrypted data are fully/partially reflected in the decrypted data. For example, if the input data D is homo-morphically encrypted to E, and if we perform X=E+N, then while decrypting X, we are bound to get D+N. Such a kind of encryption helps data owners to safely share their data among different analysers, without the risk of any kind of data leakages. Data analysers usually perform mathematical operations on the data which include addition, subtraction, multiplication and division. Homo-morphic systems which support addition & subtraction but do not support multiplication and division are termed as partially homo-morphic systems. While systems which support all the operations are termed as fully homo-morphic systems. In this paper, we have implemented a fully homo-morphic system based on Lagrange’s functions. These functions help in improving the overall security of the system by adding stochastics to the input data, which ensures that the same input data has different cipher text, and full homo-morphism is achieved. Security of overall system increased by 40% by using FHE.

A violência contra a mulher negra no conto "Maria" de Conceição Evaristo
Authors: David Nismária Alves , Balisa Fernanda Francisca
Published: July 2020

Na sociedade brasileira contemporânea, é constatado diariamente o aumento da violência de diversas formas, sendo o preconceito racial uma delas. Vale ressaltar que sua intensidade se amplia quando é direcionada à mulher negra e pobre. Ao verificar a necessidade da discussão sobre o assunto violência contra a mulher negra, que tanto se manifesta no contexto urbano, foi escolhido o objeto deste estudo - o conto “Maria”, publicado em Olhos D´Água (2015) pela autora Conceição Evaristo. Trata-se de uma escritora de renome no campo da Literatura Afro-brasileira, a qual aborda especialmente a condição feminina a partir do conceito, por ela formulado, de escrevivência, isto é, a escrita das vivências de um corpo feminino negro no contexto pós-colonial do Brasil. Como embasamento teórico, utilizam-se as perspectivas do Pós-colonialismo, segundo Homi Bhabha (1998) e Gayatri Spivak (2010), e organiza-se o texto em duas partes: na primeira parte, apresenta-se Conceição Evaristo e suas ideias sobre a Literatura Afro-brasileira; e, na segunda parte, por sua vez, analisa-se o conto, discutindo a violência e o preconceito racial sofridos pela protagonista do enredo. Os resultados revelam a Literatura Afro-brasileira como um importante lugar de resistência que dá visibilidade aos negros e mestiços.
Memórias da escravidão e ancestralidade em Ponciá Vicêncio de Conceição Evaristo
Authors: Baldo Heloisa Gaiardo
Published: July 2020

Resumo: este trabalho propõe um estudo analítico do romance Ponciá Vicêncio (2003) da escritora Conceição Evaristo, enquadrando-o na tradição literária afro-brasileira. A poética da escrevivência de Evaristo procura aproximar-se de elementos e práticas sociais presentes em algumas etnias africanas. Nosso objetivo é verificar como estão articuladas as memórias do passado escravocrata com a preservação da ancestralidade africana na narrativa. Sendo assim, procuraremos no texto de Evaristo símbolos ligados à ancestralidade que propõem uma volta simbólica às origens dos afrodescendentes, que por usa vez contribuem para a criação de um novo imaginário coletivo, livre de racismo.

O objetivo deste artigo é calcular um índice de qualidade de vida para os municípios sergipanos no ano de 2010. A partir da análise empírica espera-se identificar quais fatores que mais/menos contribuem para a qualidade de vida municipal. Para a construção desse índice utiliza-se a análise fatorial, aplicada a um conjunto de dados socioeconômicos e de infraestrutura urbana. Os principais resultados revelam uma superioridade em termos de qualidade de vida dos municípios situados nas proximidades da região metropolitana de Aracaju. Por outro lado, os piores resultados foram constatados nos municípios sergipanos localizados na região Centro-Sul e no Alto São Francisco.
Three-Phase Step Voltage Regulator Model for the Z-Bus Power Flow
Authors: Pompodakis Evangelos
Published: July 2020

This letter presents a comprehensive Step Voltage
Regulator (SVR) model suitable for the three-phase ZBUS power flow. The
model can be applied in all SVR configurations such as open delta, close delta,
wye. Its advantage is that the tap variations are simulated outside the YBUS
matrix, without compromising the convergence of the power flow. Therefore, a
refactorization of the YBUS matrix is not required after every tap
change reducing significantly the computation time of the power flow. The
proposed SVR model is validated in a 4-Bus network, while its performance is
tested in the IEEE 8500-Node test feeder.
