Authors: VIMALA KUMAR KURAKULA , G.Sritej  , V.Ganesh
Published: December 2020

This paper presents three area multi-unit Deregulated Power System (DPS) for Load Frequency Control (LFC) using Fractional Order Sliding Mode Controller (FOSMC) along with Thyristor Controlled Phase Shifters (TCPS) and Superconducting Magnetic Energy Storage (SMES) combination. The FOSMC can be used to overcome nonlinearities and uncertainties of the system for bilateral and unilateral transactions under diﬀerent Step Load Perturbations (SLPs). The deregulated power system performance is analyzed for diﬀerent Regulation constants (R) such as 1.8, 2.4 and 3.0. For stabilization of oscillations in frequency and to stabilize the deregulated power system dynamically for diﬀerent SLPs, TCPS is incorporated with the tie line in series and SMES is used as an energy storage unit. The dynamic responses of LFC problems have been simulated and analyzed with MATLAB/Simulink-based computer simulations. Further simulation results have also been tabulated as a comparative performance with respect to peak overshoot and settling time.

Published: December 2020

In this era, the occurrence of vehicle theft has become a fairly frequent problem, especially in big cities like Jakarta and Surabaya. Although the technology for car security is very sophisticated (e.g. keyless system), but there are many cases that thieves still can break into the system. Once a car was stolen, the whereabouts of the car was unknown and the thief was on the loose. The goal of this research is to overcome this problem. As a device, this research works on Raspberry Pi 3 that connected with the Raspberry Pi Camera. Using the OpenCV library, with the Haar Cascade method for face detection, and Local Binary Pattern Histogram for face recognition. The device must be connected to the internet in order to send the information using a Telegram message. The research results show the success of the device system in face-recognizing between the car owner and car thief with optimal conditions in the morning until the afternoon with the light intensity around 660 to 1000 lux, and best recognizing distance at 50 cm. The success rate for obtaining the car’s location for the outdoor condition is 100%. Even if there is a slope or an error data, it can be tolerated because the difference was not too high, about 0.1-1.0 m.

The quality of cow’s milk and the spread of mastitis greatly depend on the level of udder hygiene. Our author’s research was conducted to evaluate the effects of Forticept® Udder Wash and Forticept® Udder Forte, used before and after milking, on the treatment and prevention of subclinical mastitis and hyperkeratosis of cows’ udders. A total of 6880 milk samples were taken from 430 cows, 3-4 years old, 470-490 kg weight, at 60 ± 15 days of lactation. The therapeutic efficacy coefficient (EC) of Forticept® polymers based on benzetonium and benzalkonium chloride, against the subclinical form of mastitis was 73.8% compared to iodine-containing agents; preventive EC - 32.4%. Dipping hygiene of the udder using Forticept® on the 30th day reduced the number of 1-3 stage teat hyperkeratosis cases from 78.8% to 41.3%. Also, during this period, a significant (P<0.05) improvement in the chemical parameters of the milk was observed - an increase in fat (up to 3.94 ± 0.08%), protein (3.35 ± 0.07%), casein (3.15 ± 0.09%) and dry matter (14.91 ± 0.28%). After using Forticept®, the total bacteria count (TBC) of the milk decreased to 3×105 CFU/cm3, and the somatic cell count (SCC) - to 130 thousand/cm3 (P<0.05). Test day milk yield (TDMY) increased by 1.15% due to efficient dipping with Forticept® (P<0.05).

Acid-base disturbances have been reported in severe canine babesiosis caused by Babesia rossi (B. rossi), but they have not been studied in babesiosis caused by B. canis. The objective of this study was to determine the acid-base status, blood gases and electrolyte concentrations in naturally occurring canine babesiosis caused by B. canis, and to compare the results to those in healthy dogs. Two groups of animals were used: group 1 consisted of 10 healthy dogs, and group 2 consisted of 14 dogs naturally infected with B. canis. The following acid-base disturbances occurred in the dogs with naturally occurring babesiosis: half of the dogs had a mixed acid-base disorder, and the other half a simple acid-base disorder. The most common mixed disorder was metabolic acidosis with metabolic alkalosis. It may be said that a variety of acid-base disorders occurs in canine babesiosis. The dogs in the present study had metabolic acidosis due to hyperlactemia and hyperchloremia, metabolic alkalosis due to hypochloremia and hypoalbuminemia, and respiratory alkalosis due to hypoxemia. With the use of the strong-ion difference approach clearer recognition of mixed acid-base disorders and their better understanding is possible.

Authors: Stachowska Sylwia
Published: December 2020

Rozwój gospodarki opartej na wiedzy, wysoka konkurencyjność i zmiany na rynku pracy, a także zmiany pokoleniowe w strukturze zatrudnienia, wymuszają na organizacjach zmianę paradygmatu zarządzania, związaną z koniecznością poszukiwania i wdrażania nowych, bardziej efektywnych metod i koncepcji w sferze zarządzania kapitałem ludzkim. Racjonalnie myślący pracodawca wie, że współcześnie o konkurencyjności nie decydują wyłącznie posunięcia rynkowe, ale także inwestowanie w pracowników i stosowanie różnorodnych narzędzi sprzyjających odpowiedniemu budowaniu i wykorzystaniu ich potencjału jako kluczowego czynnika sprzyjającego efektywności, osiąganiu celów organizacyjnych oraz przewagi konkurencyjnej. Marzeniem wielu firm jest obecnie posiadanie kompetentnych, zaangażowanych i przywiązanych do organizacji pracowników, którzy będą przy tym najlepszymi ambasadorami ich marki w otoczeniu, kształtując pozytywny wizerunek i reputację organizacji również jako atrakcyjnego pracodawcy, dla którego kapitał ludzki jest ważną wartością. Spełnienie tego marzenia wymaga zwycięskiego przejścia przez pełną wyzwań drogę „od zaangażowania pracowników do marki pracodawcy”, co wiąże się z koniecznością zmiany tradycyjnego modelu zarządzania zasobami ludzkimi w kierunku budowy i rozwoju modelu opartego o nowoczesne podejścia. Celem niniejszego opracowania jest zaprezentowanie wybranych nowoczesnych koncepcji w zarządzaniu kapitałem ludzkim współczesnych organizacji, ze zwróceniem uwagi na ich główne obszary działań, korzyści wynikające z ich wdrożenia, ale także wyzwania z tym związane. Opracowanie ma charakter przeglądowy. Podstawą realizacji celu jest analiza literatury przedmiotu w obszarze podejmowanej problematyki, z uwzględnieniem zawartego w niej dorobku badawczego. Opracowanie zostało podzielone na dwie części. Tematyka przedstawiona w części drugiej nawiązuje do ważnych obszarów związanych z kreowaniem wizerunku firmy jako pracodawcy. W rozdziale pierwszym poruszona została problematyka społecznej odpowiedzialności biznesu (CSR), głównie z punktu widzenia roli, jaką odgrywają działania społecznie odpowiedzialne ukierunkowane na pracowników. W rozdziale drugim przedstawiona została koncepcja zarządzania wiedzą w organizacji, ze szczególnym uwzględnieniem jej powiązań z zarządzaniem zasobami ludzkimi. Natomiast rozdział trzeci prezentuje istotę i znaczenie employer brandingu jako nowoczesnej strategii budowania marki pracodawcy z wyboru, ze zwróceniem uwagi na rolę, jaką w tym zakresie odgrywają działania podejmowane w obszarze HR.

Deep excavation in areas with very soft clay deposits need a good soil retaining system and excavation method. Using a diapraghm wall as a soil retaining system for deep excavation is a good choice can be done. Diapraghm wall is expected to limit the movement that occurs in the retaining walls and avoid leaks that occur in walls, this is needed to minimize damage to adjacent buildings. The top down excavation method by utilizing the basement floor as lateral resistance can be carried out to reduce the movement that occurs on the ground. In very soft soil areas with excavation distances to neighbors very close, the movement on the ground must be limited to minimize damage to adjacent buildings. Cross walls can be used to reduce the movement that occurs on the ground. Analysis of finite element with using the Plaxis program was carried out to investigate the performance of the retaining wall. From the results of the analysis conducted shows that using a cross wall at a location below the raft pile can be reduced the movement that occurs in the retaining wall and the excavation stages can be reduced. Keywords: cross wall; deep excavation; diapraghm wall; very soft soil ABSTRAKGalian dalam pada daerah dengan endapan tanah liat sangat lunak yang cukup dalam diperlukan sistem penahan tanah dan metode galian yang direncanakan dengan baik. Menggunakan dinding dipraghm sebagai sistem penahan tanah untuk galian dalam merupakan pilihan yang dapat dilakukan. Penggunaan dinding diapraghm diharapkan dapat membatasi pergerakan yang terjadi pada dinding dan menghindari kebocoran yang yang terjadi pada dinding penahan tanah karena sistem pengecoran yang saling mengunci dan pertemuan antara panel dinding dapat dipasang waterstop, hal ini diperlukan untuk menghindari kerusakan pada bangunan yang berdekatan dengan daerah galian. Metode galian top down yaitu galian bertahap dengan memanfaatkan lantai besmen sebagai tahanan lateral dapat dilakukan untuk mengurangi pergerakan yang terjadi pada tanah. Pada daerah tanah sangat lunak dengan jarak galian dengan tetangga sangat berdekatan pergerakan pada tanah harus dibatasi untuk meminimalkan kerusakan pada bangunan yang berdekatan. Dinding silang merupakan sistem tahanan lateral yang dapat dipergunakan untuk mengurangi pergerakan yang terjadi pada tanah. Analisis elemen hingga menggunakan program Plaxis 2D dilakukan untuk mengetahui kinerja dinding penahan tanah dan pergerakan yang terjadi. Dari hasil analisis yang dilakukan diperoleh hasil bahwa dengan menggunakan dinding silang yang terletak pada di bawah raft pile dapat menurunkan pergerakan yang terjadi pada dinding penahan tanah dan tahapan galian dapat dikurangi.

The flotation of deposits from two recently excavated Kalenderberg Group cremation graves in DevínZáhrady (SW Slovakia) yielded a plethora of archaeozoological and archaeobotanical remains, including small, otherwise overlooked, ecofacts. The results of our analysis in the context of contemporary data show that animals clearly constituted an unambiguous part of funerary ritual activities. Pig, fish, red deer, cattle and caprines were all exploited at Devín-Záhrady. These animals represented both food and symbolic offerings, with a preference for pig and fish. Cattle, red deer, pig and caprines astragali found in grave 2 were all associated with one of the urns. The age of perinatal piglets was used to indicate the season when the funerals took place. Plant macro-remains are much less common than bone remains and are not associated with the burial. The results of the analysis change what is known about the array, quantity and way animal and plant offerings from Kalenderberg Group cremation graves were prepared for the burial ritual. Their study also permitted residual and intrusive materials to be detected, allowed reconstruction of the deposit’s formation processes and establishment of the connections (or absence of connections) between these ecofacts to the funeral and/or burial ritual.

The creation of synthetic polymer nanoobjects with well-defined hierarchical structures is important for a wide range of applications such as nanomaterial synthesis, catalysis, and therapeutics. Inspired by the programmability and precise three-dimensional architectures of biomolecules, here wedemonstrate the strategy of fabricating controlled hierarchical structures through self-assembly of folded synthetic polymers. Linear poly(2-hydroxyethyl methacrylate) of different lengths are folded into cyclic polymers and their self-assembly into hierarchical structures is elucidated by various experimental techniques and molecular dynamics simulations. Based on their structural similarity, macrocyclic brush polymers with amphiphilic block side chains are synthesized, which can self-assemble into wormlike structures and higher-ordered networks. Our work points out the vital role of polymer folding in macromolecular self-assembly and establishes a versatile approach for constructing biomimetic hierarchical assemblies.
Spatial Segmentation of Mass Spectrometry Imaging Data by Combining Multivariate Clustering and Univariate Thresholding
Authors: hu hang , yin ruichuan , Brown Hilary , Laskin Julia
Published: December 2020

Spatial segmentation partitions mass spectrometry imaging (MSI) data into distinct regions providing a concise visualization of the vast amount of data and identifying regions of interest (ROIs) for downstream statistical analysis. Unsupervised approaches are particularly attractive as they may be used to discover the underlying subpopulations present in the high-dimensional MSI data without prior knowledge of the properties of the sample. Herein, we introduce an unsupervised spatial segmentation approach, which combines multivariate clustering and univariate thresholding to generate comprehensive spatial segmentation maps of the MSI data. This approach combines matrix factorization and manifold learning to enable high-quality image segmentation without an extensive hyperparameter search. In parallel, some ion images inadequately represented in the multivariate analysis are treated using univariate thresholding to generate complementary spatial segments. The final spatial segmentation map is assembled from segment candidates generated using both techniques. We demonstrate the performance and robustness of this approach for two MSI data sets of mouse uterine and kidney tissue sections acquired with different spatial resolutions. The resulting segmentation maps are easy to interpret and project onto the known anatomical regions of the tissue.

We developed a methodological workflow combining size exclusion chromatography, native isoelectric focusing, and high sensitivity X-ray-based metal detection within electrophoresis gels to analyze the metal content of single proteins purified from minimal amounts (<20 mg) of post-mortem human brain and spinal cord tissue. An important metalloprotein in the human central nervous system is copper-zinc superoxide dismutase (SOD1), an antioxidant enzyme linked to the aetiology of both amyotrophic lateral sclerosis and Parkinson’s disease. Abnormal SOD1 metallation is suspected to play a role in the pathogenic aggregation of SOD1 in both disorders, although data describing SOD1 metal occupancy in human tissues has not previously been reported. Validating our novel approach we demonstrated step-by-step metal preservation, preserved SOD1 activity, and substantial enrichment of SOD1 protein vs confounding metalloproteins. We found Cu and Zn were bound to SOD1 in a ratio of 1.12 ± 0.28 in human central nervous system tissues from healthy individuals, a ratio close to the expected value of 1. Our methodological workflow can be adapted to study a range of metalloproteins from human tissues and other sources.

The quest for planar sp2-hybridized carbon allotropes other than graphene, such as graphenylene and biphenylene sheet, has stimulated substantial research efforts because of the materials' predicted unique mechanical, electronic and transport properties. However, their synthesis remains challenging due to the lack of reliable protocols for generating non-hexagonal rings during the in-plane tiling of carbon atoms. Here, we report the bottom-up growth of ultra-flat biphenylene sheet with periodically arranged four-, six-, and eight-membered rings of sp2 carbon atoms, via an unprecedented on-surface inter-polymer hydrogen fluoride (HF)-zipping reaction. The characterization of this biphenylene sheet by scanning probe methods solves the long-standing controversy over its dielectric or metallic nature. We expect the inter-polymer HF-zipping method to complement the toolbox for the synthesis of other nonbenzenoid carbon allotropes.
Visible-Light Induced Singlet Nucleophilic Carbenes: Rapid and Mild Access to Fluorinated Tertiary Alcohol Derivatives
Authors: Priebbenow Daniel , Pilkington Rowan , Polyzos Anastasios
Published: December 2020

Singlet nucleophilic carbenes (SNCs) that contain only one heteroatom donor remain underexplored and underutilized in chemical synthesis. To discover new synthetic strategies that harness these SNCs as reactive intermediates, aromatic or aliphatic siloxy carbenes represent excellent model substrates as they can be readily generated photochemically from stable acyl silane precursors. We herein report the discovery that photochemically generated siloxy carbenes undergo 1,2-carbonyl addition to trifluoromethyl ketones, followed by a silyl transfer process to afford benzoin-type products. This new transformation is a rare example of the use of ketones as trapping reagents for SNC intermediates and delivers an efficient, user-friendly and scalable process to access fluorinated tertiary alcohol derivatives driven by only light, circumventing the use of catalysts or additives.

Introduction: Mycobacterium leprae infiltration results in inflammation of the nerves. This condition results in a progressive decline of nerve function of the eyes, hands and feet. The main burden of people with leprosy is a disability that will affect all aspects of their lives. The objective of this study was to explain the effect of empowerment education, home-based self care, and peer support for disability. Methods: True experimental randomized pre-post test control group design. The sampling technique used simple random sampling consisted 16 respondents. The independent variable was empowerment education, home-based self care, and peer support. The dependent variable was disability. The data were collected by in-vivo biological observation sheets. The data were analyzed by Mann-Whitney Test and Wilcoxon Signed test. Results: The result showed that there was an effect of intervention on disability with Wilcoxon Sign Rank Test 0.046. Discussion: Empowerment education interventions, home-based self care, peer support increase the knowledge of leprosy clients in self care. The key to disability prevention is 3M, which is checking, protecting, and caring for the eyes, hands and feet. These three interventions will increase patient confidence in self-care at home. The support of peers will also make it easier for clients to weigh the advantages and disadvantages when not complying with comprehensive treatment.

Published: December 2020

HIV infection during pregnancy is a serious problem that requires special attention because the number of case increasing every year. According to UNAIDS data, more than 36.9 million people were living with HIV on 2017. An increase of 1.8 million new cases and 940,000 deaths occurs in the same year. In Indonesia especially, there were about 630,000 HIV cases on 2017 and nearly 49,000 new cases reported. This number consists of cases of vertical transmission from mother to child during pregnancy. The government has implemented PMTCT (Prevention Mother to Child Transmission) program as a solution to reduce the number of HIV cases. Nevertheless this program has not been running well due to several barriers regarding to its implementation. This study aimed to provide an understanding of various barriers to PMTCT program implementation. A systematic review approach by PRISMA design was used to study literatures from databases. Stigma or discrimination from community and health care, experienced by HIV patients, was major barrier that impede PMTCT program. In addition, lack of support from partner or family, depression, economic factors, stigma from health workers, and health workersâ€™ income-workload discrepancy were also significantly affected the implementation. Contrary, the active role of health workers to provide counseling and education about HIV/AIDS among community as well as to clientâ€™s families was a success key of PMTCT program.

Published: December 2020

In the conditions of the modern economic development, its focus on sustainable development and environmental problems are of paramount importance. The directions of achieving environmental sustainability in Russia are supposed to be solved through the implementation of a set of measures outlined in the national project “Ecology”, which sets a number of targets and additional indicators that contribute to solving environmental problems. The article is devoted to the factors influencing the implementation of national projects and programs in the field of ecology in the Russian Federation. An analysis of the implementation of the “Ecology” project and the state program of the Russian Federation “Environmental Protection” as well as the study of Russian and foreign practices (experience of Singapore, Great Britain, Germany and other countries) regarding the monitoring the implementation of strategic documents, have helped to identify the relevant risks and to conduct their assessment, with the aim of increasing the effectiveness of financial control over the implementation of the national project. On the basis of the identified risks, the targets of the “Ecology” project were identified, which, in the opinion of the authors, requires its revision in order to be more effective. The results of the study may be interesting as relevant state bodies responsible for the implementation of the national project “Ecology”, in particular, the Ministry of Natural Resources and Ecology of the Russian Federation, as well as bodies which are monitoring its implementation, for example, the Accounts Chamber of the Russian Federation.

El cáncer de mama es una de las enfermedades que más afectan a las mujeres, y que tiene una importante morbilidad, en los casos en donde es detectado a tiempo, se utilizan técnicas que no necesariamente deben incluir un procedimiento quirúrgico (quimioterapia y radioterapia). Pero independientemente de ello, la mejor técnica a utilizar la va a dar la localización del cáncer y lo avanzado que este. La metodología de la investigación, es una revisión bibliográfica, que se ha obtenido de ubicación por medios electrónicos de trabajos de investigación que se han publicado sobre el tema de estudio, y lo que se busca es generar una síntesis de todo lo recopilado, que pueda generar a futuro nuevas investigaciones. Las conclusiones generales a las que se ha podido llegar, es que existen muchas técnicas quirúrgicas para afrontar el cáncer mamario, dependiendo de que tan avanzado no o este. Las más severas son las mastectomías, encontrándose técnicas más conservadoras y no tan invasivas, sin embargo, las cirugías oncoplásticas han estado ganado terreno por que han logrado preservar las glándulas mamarias.

The Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier, 1790) is a devastating invasive pest of palm trees, invading the Iraqi date palm tree in 2015 for the first time in Safwan county, Basrah province. The Red Palm weevil has been categorized as a quarantine pest of date palm trees worldwide. In this study, a five years monitoring program has been achieved by scouting the invasive pest RPW population in Safwan county by using visual sampling and Pheromone baited traps. The results indicated that the number of infested palms, increased from 12 trees in 2015 to 111 in 16 orchards in 2016. The number of the infested palms was minimized to 3 trees in the county in 2019 due to the management protocol of the Ministry of Agriculture. Furthermore, the results of RPW adults appeared monthly in the county with two activity peaks during the moderate-temperature-months. In conclusion, the quarantine and management protocol of RPW decreased the population of the invasive pest which did not spread to other districts of Iraq.

The Sutong Bridge being currently constructed in Jiangsu Province, China, is the world’s longest cable-stayed bridge with a main span of 1088 m. With the purpose of securing the operational and structural safety of the bridge throughout its 100-year life span and facilitating the bridge inspection and maintenance, a sophisticated long-term structural health monitoring system, called Structural Health Monitoring and Safety Evaluation System, has been devised and is being implemented in synchronism with the bridge erection progress. This paper outlines technology achievements in the research and design of this monitoring system through exploring its five modules: (i) sensory system (SS); (ii) data acquisition and transmission system (DATS); (iii) data processing and control system (DPCS); (iv) structural health evaluation system (SHES); and (v) portable data acquisition system (PDAS).

Published: December 2020

Este artigo tem como propósito analisar a questão das migrações transnacionais no âmbito de três países americanos, Brasil, Colômbia e Estados Unidos da América, a partir de duas questões dimensionais: 1) Qual é autonomia dos Estados em relação ao nível de controles fronteiriços e de identidade nacional? 2) De que forma o controle de fronteiras de cada país é necessário para manter a segurança interna, tanto econômica quanto social? Nesse sentido, um fluxo imigratório específico foi dedicado a cada um dos três países em tela: os haitianos no Brasil, os venezuelanos na Colômbia e os mexicanos nos Estados Unidos da América. Questões de controle fronteiriço e identidade nacional foram igualmente levantadas a fim de compreender as repercussões de tais fenômenos migratórios nos países de acolhimento.

Authors: Nogueira Vera Maria Ribeiro , Da Cunha Frederico Rotta
Published: December 2020

Este artigo é uma primeira aproximação sobre o impacto social da pandemia provocada pelo Covid-19 em cidades gêmeas na região do MERCOSUL. O objetivo é relacionar as medidas propostas pelos governos nacionais com as consequências na região transfronteiriça em sua dupla dimensão: foco de entrada do novo coronavírus e espaço de vivência cotidiana dos habitantes. Identifica a repercussão das medidas em dois segmentos populacionais residentes em duas regiões transfronteiriças - agentes estatais e população residente. Sua construção apoia-se em publicações governamentais, da imprensa nacional e local, informes das agências multilaterais e entrevista com gestor local de assistência social. Os principais resultados indicam a relevância de pactos informais quando efetivos, a ausência de menções a organizações e pactos binacionais, a interferência na reprodução social nos segmentos analisados e o protagonismo dos agentes locais.
Implicaciones de la Covid-19 sobre pacientes con VIH/Sida en Latinoamérica
Authors: Prince Torres Ángel Carmelo
Published: December 2020

Este artículo fue elaborado con el propósito de estudiar las implicaciones que la pandemia de Covid-19 ha producido sobre los pacientes con VIH/Sida en Latinoamérica. Por esta razón fue estructurada una investigación documental, para determinar las consecuencias de los movimientos fronterizos entre territorios como los de MERCOSUR, sobre las estructuras sanitarias que brindan atención a dichos sujetos. Se determinó que los Estados, desde la elaboración de sus políticas públicas sobre sistemas de salud y fronteras, pueden reconducir esfuerzos para establecer mejores prácticas en el control de los espacios limítrofes, de manera que reduzca el peso sobre los sistemas de salubridad nacionales, y de esta manera no se continúen desviando los recursos para atención de personas seropositivas en áreas de abordar la emergencia por coronavirus. Del mismo modo, se destaca que las estrategias concebidas con tales propósitos deben estar ajustadas a las normas jurídicas internacionales en materia de derechos humanos y a la cooperación multiestatal.

Este artículo de revisión presenta un análisis de la política de salud en territorios fronterizos, en un momento de pandemia. El equipo de investigadores ha decidido redactar un documento que refleje de manera objetiva y sintética la forma en que los estados de Paraguay y Brasil se encuentran afrontando el avance de la pandemia del Covid-19, mediante la implementación de diversas políticas de salud que desde el lado Paraguayo, en un principio han buscado aplanar la curva de contagio de tal forma a evitar el colapso del sistemas de salud pero sin embargo en el lado brasileño la situación se ha dado a la inversa, ya que el gobierno ha manifestado abiertamente su incredulidad a la pandemia, tomando medidas gubernamentales mínimas, lo que ha llevado a un acelerado y vertiginoso contagio masivo convirtiendo en pocas semanas al Brasil en el epicentro de pandemia. El objetivo del artículo es reflejar las vivencias de paraguayos y paraguayas residentes en las ciudades gemelas (Foz/ CDE) en el contexto de la pandemia Covid-19, respecto a las respuestas brindadas por ambos estados para garantizar su derecho a la salud. Para ellos se optó como metodología de trabajo realizar un relevamiento bibliográfico sobre la legislación vigente a nivel nacional e internacional que garantizan los derechos de las personas residentes en zonas de frontera, especialmente aquellas referentes al derecho a la salud, describiremos las medidas sanitarias tomadas por los gobiernos ante el avance de la pandemia y el impacto de las mismas en la vida de los ciudadanos, seguidamente analizaremos las restricciones impuestas y la legalidad de las mismas, , finalmente realizaremos dos entrevistas semi estructuradas a ciudadanos residentes en Foz de Yguazu y una entrevista a un residente en Ciudad de Este para conocer sus vivencias durante esta pandemia y las respuesta ofrecidas por ambos países para garantizar su derecho a la salud.

Polymer flooding is a widely used enhanced oil recovery (EOR) technology. The purpose of the polymer is to increase water viscosity to improve reservoir sweep efficiency. However, mechanical elements of the polymer injection facilities may impact the viscosity of the polymer negatively, decreasing it drastically. Mechanical degradation of the polymer occurs in case of flow restrictions with abrupt diameter changes in valves and control systems. Such flow restrictions may induce mechanical stresses along the polymer chain, which can result in its rupture. In this research, physical experiments and numerical simulations using CFD (Computational Fluid Dynamics) were used to propose a model for estimating the mechanical degradation for the flow of polymer solutions. This technique involves the calculation of velocity gradients, pressure drawdown, and polymer degradation of the fluid through geometry restriction. The simulations were validated through polymer injection experiments. The results show that with the greater volumetric flow and lower effective diameters, there is more mechanical degradation due to polymer shearing; nonetheless, this depends on the rheology properties inherent in each polymer in an aqueous solution.
This method is suitable to estimate the mechanical degradation of the polymer solution in flooding facilities and accessories. Further, the results obtained could enhance the use of the polymer, calculating its actual mechanical degradation, minimizing it, or using it to support the development of new accessories.
