Authors: Cunha Francisco Valmor Macedo , Sousa Joana D'arc Alves , Alves Jonas Almeida
Published: February 2021

Background: Computerized baropodometry, a posturographic recording technique used in the diagnosis and assessment of plantar pressure, which records the pressure points exerted by the body on the plantar surface, is an accurate, objective and quantitative examination. Its record is used in the diagnosis and evaluation of plantar pressure, both in static and dynamic positions. Objective: Analyze the baropodometric profile of patients in a physiotherapy clinic. Methods: A cross-sectional study of documentary character of baropodometry exams registered in the database of a physiotherapy clinic in Teresina (PI), carried out from January 2015 to December 2018. Totaling 193 exams, which include the types of feet, peak plantar pressure and correlation between peak plantar pressure with age, weight, height and BMI. The collected data were analyzed statistically by the software Win Track version 12.0, and presented through tables and figures. In this research, all ethical precepts were carried out in accordance with the resolution of the National Health Council and was approved by the ethics committee. Results: There was a higher prevalence of hollow feet (96.89%), showing a greater occurrence of displacement of the center of gravity posteriorly to the right (46.11%), it was found that there was no satisfactory correlation of anthropometric parameters with peak plantar pressure (p>0.05). Conclusion: It was possible to observe that the examinations evaluated showed a higher prevalence of hollow feet and center of gravity posteriorized to the right. In addition, there was no satisfactory correlation between peak plantar pressure with the variables age, weight, height and BMI.
Determinants of internet use by the elderly in Spain: time dedicated to search and communications
Authors: Campaña Juan Carlos , Ortega Raquel
Published: February 2021

Internet use reduces the isolation or exclusion of individuals in specific socio-economic groups and, consequently, increases the quality of life, with this being especially the case for the elderly. Knowing that the elderly are becoming particularly active in dedicating time to the Internet, we provide evidence of the time that Spanish individuals aged 65 and older dedicate to two online activities: search and communications. We estimate a SUR model with data from the STUS for 2009-2010. Our main results indicate that being male has a positive influence on the time devoted to search on the Internet. Furthermore, time devoted to both Internet activities increases with higher levels of education and at the highest level of individual health.
Sistema Acusatório Princípio Processual Penal Implícito na Constituição
Authors: Garcia Paulo Sergio
Published: February 2021

ResumoO artigo em questão propôs abordar sobre o sistema acusatório princípio processual penal implícito na Constituição Federal e a forma de ser interpretado na Constituição Federal de 1988 pelos doutrinadores. O sistema processual brasileiro apresenta como características seus traços inquisitórios, acusatórios e o misto. O inquisitivo é um sistema pelo qual as duas funções de acusação e julgamento se apresentam unidas em um único órgão ou em uma única pessoa, e o sistema acusatório, os papéis são reservados para pessoas ou órgãos distintos. No entanto, como observado na literatura, são apresentados conflitos na forma de interpretação dos sistemas. Muitos autores expressam suas posições, uns sustentam que o sistema adotado no Brasil é o inquisitório, outros apontam ser um sistema misto, mas outros afirmam ser o sistema acusatório. Infelizmente, o que se observa através das várias interpretações apresentadas sobre o sistema acusatório, é que este continua preso às amarras do inquisitorialismo. Nestes últimos anos, verifica-se que vêm sendo travadas lutas doutrinárias incessantes, pois se percebe a grande necessidade de transformações, que se tornam urgentes. Estas lutas têm propósitos importantes, objetivam a busca da afirmação de um direito processual penal que seja pautado pela conformidade constitucional. Palavras-chave: Constituição. Princípio Processual. Sistema Acusatório. AbstractThe article in question proposed to address the implicit principle in the Constitution adversarial system of criminal procedure and the way it is interpreted in the Federal Constitution of 1988 by the jurists. The Brazilian legal system has as its characteristics inquisitorial, accusatory and mixed traits. The questioning is a system by which the two functions of prosecution and trial are presented together in a single organ or a single person, and the adversarial system, the roles are reserved by different persons or bodies. But as noted in the literature, conflicts are presented in the form of interpretation systems. Many authors express their positions, some argue that the system adopted in Brazil is the inquisitorial one, others point to be a mixed system, but others claim to be the adversarial system. Unfortunately, what is observed through the various interpretations presented about the adversarial system, this is still tied to the shackles of inquisitorialism . In recent years, it seems that incessant doctrinal struggles have been waged, as it is possible to the great need of transformations that become urgent. These struggles have important purposes, aimed to search the assertion of criminal procedural law that is guided by constitutional compliance. Keywords: Constitution. Principle Procedure. Adversarial System.

Męka dwuznaczności i egzorcyzmy
Authors: Tomaszewska Grażyna B.
Published: February 2021

The topic of the study is one of the last poetry volumes by Czesław Miłosz entitled The Second Space (Pol. Druga przestrzeń), through which the author of the article looks at the complications of Miłosz’s ambiguous religiousness. It is full of tension and contradictions to which the poet tries to address with various results. Miłosz avoids easy solutions, typical for common faith. The article talks about Miłosz’s longing for the explicitness as a form of protest against evil and terror of this world, a form of protest against its ambiguous dimension, which forces the acceptance of passing, suffering, decay, death. It shows various forms of transgression of the antinomy created by the coexistence of beauty and the cruelty of life (i.a. experience of epiphany) and juxtaposes its specific character of his existential axiology.

Apart of sentimentally conventionalized narrative structure the work of Dmochowski is perceived by its editor, Andrzej Edward Koźmian, in the way that indicates a publishing manner of sentimentalism. The publisher in his Preface creates the author of memoirs according with sentimental anthropological patterns and explains this creation referring sentimental axiology which he consents to.
Escape from Etymology? A Corpus Study of Polish Adjectival Intensifiers
Authors: Dziwirek Katarzyna
Published: February 2021

Using the Polish National Corpus (NKJP), the author discusses 31 Polish reinforcing adverbs to determine the degree of their semantic specificity and freedom of connection with adjectives. Empowering adverbs express the person’s judgement, attitudes, and emotions. The author shows that most of the reinforcing adverbs have not deviated from their etymology, even though they are considered synonyms of the word “very”: their etymological meanings influence the choice of the adjective. The most frequently reinforced adjectives in NKJP are “difficult”, “important” and “essential”.

A Mini-Review and Perspective on Anti-hypoxic Hypothesis of COVID-19
Authors: Shamshirian Amir , Shamshirian Danial , Hosseinzadeh Mohammad Hossein , Ebrahimzadeh Mohammad Ali
Published: February 2021

A novel coronavirus emerged in Wuhan, China; in December 2019 and has widely affected the global community. After months of extensive effort, much remains to be understood of the pathogenesis of Coronavirus Disease 2019 (COVID-19). The available evidence raises a critical question : Is COVID-19 a lung disorder leading to circulatory problems, or a systemic disorder that leads to lung problems?. If the latter scenario is correct, investigations on hypoxia conditions and the development of anti-hypoxia agents may lead to potential front-line treatments in combination with antivirals for hypoxemic COVID-19 patients. Hence, anti-hypoxic agents may become a potential part of combination therapy in hypoxemic respiratory failure and COVID-19.
A Review on Prevention, Transmission and Symptoms of the Covid-19
Authors: Mohammadi Hamid , Ehteshaminia Yahya , Mahdavi Seif Ali
Published: February 2021

Introduction: Coronavirus belongs to a family of viruses that can cause symptoms such as pneumonia, fever, shortness of breath and lung infection. On December 29, 2019, the World Health Organization (WHO) coined the term New Coronavirus 2019 to refer to a coronavirus that affects the lower respiratory tract of patients with pneumonia in Wuhan, China. The new coronavirus was first identified in Wuhan, among a number of patients with an unknown form of viral pneumonia who also had a history of Huanan seafood market.
Materials and Methods: In this study, the websites of PubMed, Google Scholar, SID, and Magiran were searched and related articles were reviewed.
Results: Symptoms of COVID-19 occur after a period of 2 to 10 days and the period of symptoms resulting in death of patients varied between 6 to 41 days. Common symptoms at the onset of the disease are fever, cough, and fatigue. Each carrier is reported to infect an average of 3.77 others.
Conclusion: Regarding the way of transmission of viral diseases of the upper respiratory tract, such as COVID-19, i.e., the transmission by respiratory droplets as well as close communication between individuals, solutions have been recommended by experts. Researchers are suggesting not touching the T-zone on the face, using a mask and following the principles of social distancing are the most effective ways to control the disease. Due to the lack of definitive treatment or effective vaccine for COVID-19 so far, following these principles has a significant role in combating this pandemic.

La crisis financiera internacional que originó la actual contracción de la actividad económica mundial--que por su magnitud y tiempo ha sido bautizada por historiadores económicos como la Gran Recesión--empezó en los Estados Unidos en la década pasada con la explosión de la burbuja inmobiliaria, que consecuentemente le puso el fin al boom del sector vivienda; precipitó el colapso de instituciones públicas y privadas, como Freddie Mac, Fannie Mae y Lehman Brothers en 2008; hizo del otorgamiento de créditos hipotecarios una actividad financiera disfuncional; y generó cuantiosas pérdidas de riqueza, de las que todavía no nos recuperamos.

Microeconometric modeling of rent as a measure of natural resource scarcity: regularity and technical change, scale, and functional form sensitivity under partial static equilibrium
Authors: Escalante Andrés
Published: February 2021

Esta investigación tiene dos objetivos. El primero consiste en evaluar la sensibilidad estadística de la renta  como medida de escasez de un recurso natural, hacia las especificaciones econométricas de la función de costo variable, de la que puede derivarse, con el fin de examinar si los supuestos para formular el modelo econométrico generan diferencias estadísticamente relevantes en la renta estimada. El segundo objetivo de la investigación consiste en determinar si las decisiones ejecutivas de investigación y la consistencia teórica del modelo afectan el contenido informacional de la renta,  como medida de escasez de dicho recurso. La muestra consiste en series de tiempo de 1953 a 1985 de la industria de asbestos en Canadá. Se evidencia que estas decisiones sí generan diferencias pero no como para afectar la consistencia informacional de la renta. En particular, los resultados empíricos revelan una sensibilidad de la renta ante los supuestos sobre la escala de operaciones y el cambio tecnológico y sobre todo ante las propiedades de regularidad. La consistencia informacional de la renta resulta de su movimiento unidireccional a través de las variaciones en el modelo original y que en esta oportunidad estaría sugiriendo una mayor escasez a lo largo de la muestra.

¿Puede ser un gerente un líder-coach?
Authors: García Vega Silvia
Published: February 2021

En los últimos años, la palabra coaching se escucha cada vez más fuerte en el ámbito organizacional. Las empresas están dispuestas a invertir mucho dinero para contratar coaches que ayuden a “cambiar” a sus gerentes, con el fin de convertirlos en mejores jefes, capaces de superar los resultados esperados en cuanto a metas y en cuanto a personas. Sin embargo, un proceso de coaching no busca cambiar al otro mediante instrucciones de “cómo se deben hacer las cosas”: el propósito es que el gerente descubra por sí mismo su potencial y el mundo de posibilidades que tiene a su alcance para lograr sus objetivos, apalancándose en sus fortalezas.

ISOMETRIC IMMERSIONS IN 3-DIMENSIONAL EUCLIDEAN SPACE
Authors: ÖZTÜRK Emre
Published: February 2021

In this paper, we examine the image of geodesic curves of Riemann 2-manifolds under the isometric immersions, in three dimensional Euclidean space. We show that the curvature of these curves is equal to the normal curvature of the manifold in the direction of tangent vector field of the geodesics. Moreover, we prove that if the parameter curves of the manifold are the line of curvature, then the geodesic torsion of geodesics is equal to the torsion of the image curve.
El comienzo del Feminismo Institucional en el Ayuntamiento de Madrid
Authors: Segura Ordaz Leticia
Published: February 2021

Este artículo trata el tema del Feminismo Institucional a nivel municipal a partir de la conformación de la primera Concejalía de Promoción de la Igualdad y Empleo del Ayuntamiento de Madrid en el año de 1999. El análisis se basa en la literatura sobre el tema y en una revisión histórica del proceso mediante entrevistas cualitativas y revisión documental. Después de dos décadas de la creación de la primera concejalía de igualdad del Ayuntamiento de Madrid, hay pocos estudios hechos relacionados con este acontecimiento. Con el objetivo de ampliar el conocimiento referente al Feminismo Institucional a nivel municipal, el presente artículo pretende identificar las condiciones que facilitaron la creación de la primera estructura de política de igualdad del Ayuntamiento de Madrid, enfocando la atención en los actores que formaron parte del proceso. Se concluye que los factores más influyentes que permitieron la configuración del Feminismo Institucional en el Ayuntamiento de Madrid fueron: la presencia de actores críticos como el movimiento feminista, el apoyo de partidos políticos de izquierda dentro del gobierno y la influencia de las políticas internacionales y europeas. La presencia de estos actores impulsó la introducción de objetivos feministas en la política municipal de igualdad que dio como resultado la creación del Consejo de Mujeres de la ciudad y de la figura de agentes de igualdad, dos actores que en alianza promovieron el Feminismo Institucional en el Ayuntamiento de Madrid.
Las condiciones laborales de las temporeras magrebíes en los campos de Huelva
Authors: Echajri Amhaouch Ilhame
Published: February 2021

No habrá desarrollo ni progreso humano sin igualdad real y efectiva de oportunidades entre hombres y mujeres. Por ello, toda actuación de los poderes públicos encaminada a garantizar la igualdad entre ambos sexos tendrá un efecto multiplicador que impulsará mejoras sociales y económicas a todos los niveles, beneficiando de forma especial a las mujeres más desprotegidas, entre las que se encuentran, sin duda, las trabajadoras extranjeras. El presente artículo se centra en un concreto colectivo de mujeres inmigrantes, víctimas de duras condiciones de vida y de trabajo, así como, en ocasiones, de distintos grados de violencia sexual. Me refiero a las trabajadoras, principalmente de nacionalidad magrebí, que cada año llegan a los campos de Huelva para trabajar en la plantación y/o recolección de fresas, frambuesas y arándanos. Se analizará, particularmente, la dudosa fórmula de contratación en origen utilizada, y como la misma contribuye a la precariedad laboral y vital extrema sufrida por estas mujeres.

Authors: ÜNAL KANTEKİN Çiğdem , ULUSOY TANGÜL Sevgi , ADALI İbrahim , TALİH Gamze
Published: February 2021

PURPOSE: Transversus abdominis plane (TAP) block under ultrasonography and caudal epidural block are techniques used to provide postoperative analgesia in children. The aim of this study was to compare the effect of these two analgesic techniques in pediatric inguinal hernia operations. MATERIAL AND METHOD: The study included 64 patients aged 4-12 years who underwent surgery for unilateral inguinal hernia. Caudal epidural block was applied to 33 patients (Group C) and TAP block to 31 (Group T). Routine follow-up of postoperative pain for pediatric patients was made with the Wong-Baker faces pain rating scale. A record was made for each patient of the time of requirement for additional analgesia, complications during the intervention and side-effects. RESULTS: In the evaluation of the faces pain rating scale, the scores of Group C were found to be significantly lower than those of Group T at 6, 8, and 12 hours postoperatively (p=0.04, p=0.03, p=0.03). The duration of postoperative analgesia was found to be mean 220 mins (min-max; 118.65 – 355.3 mins) for Group T, and 351.2 mins (min-max; 167.8-617.65 mins) for Group C. The time of first requirement for additional analgesia was mean 13±4.8 hours in Group C, and 8±3.5 hours in Group T (p=0.02). CONCLUSION: The application of caudal block provided more effective postoperative analgesia than TAP block applied under ultrasonography guidance in pediatric inguinal hernia repair.

Published: February 2021

Karst wetlands are being seriously damaged, and protecting it has become an important matter. Karst vegetation is the essential component of wetland and plays an important role in in the ecological functions of wetland ecosystems. Classifying karst vegetation is important for karst wetlands protection and management. This paper addressed to classify karst vegetation in Huixian National Wetland Park, located in China using the improved SegNet Deep-Learning Algorithm and UAV images. This study proposed a method to fuse single-class SegNet models using the maximum probability algorithm for karst vegetation classification, and compared with object-based RF classification and multi-class SegNet classification, respectively. This paper evaluated the performance of multi-class SegNet model and fusion of single-class SegNet model with different EPOCH values for mapping karst vegetation. A new optimized post-classification algorithm was proposed to eliminate the stitching traces caused by SegNet model prediction. The specific conclusions of this paper include the followings:(1) fusion of four single-class SegNet models produced better classification for karst wetland vegetation than multi-class SegNet model, and achieved the highest overall classification accuracy (87.34%); (2) The optimized post-classification algorithm was able to improve prediction accuracy of SegNet model, and it could eliminate splicing traces; (3) The karst wetland vegetation classifications produced by single-class SegNet model outperformed multi-class SegNet model, and improved classification accuracy(F1-Score) between 10%~25%;(4)The EPCOH values and textural feature important impact on karst wetland vegetation classifications. The SegNet model with EPCOH 15 achieved greater classification accuracy(F1-Score) than the model with EPOCH 5 or 10. The textural feature improved improves the capability of the SegNet model for mapping karst vegetation;(5) Fusion of single-class SegNet models and object-based RF model could provide high classifications results for karst wetland vegetation, and both achieved greater 87% overall accuracy.
How Do Middle-Aged Chinese Men and Women Balance Caregiving and Employment Income?
Authors: Chai Huamin , Fu Rui , Coyte Peter C.
Published: February 2021

Unpaid family caregivers might suffer losses in income as a result of care provision. Here we used data from the baseline survey of the China Health and Retirement Longitudinal Study to assess the relationship between hours of weekly caregiving provided to grandchildren/parents/parents-in-law and individual’s monthly employment income. Our study sample comprised 3,718 middle-aged Chinese adults who were of working age (45-60 years). For women and men separately, we used a likelihood-based method to determine a caregiving threshold in a two-stage Heckman selection procedure. Instrumental variables were used to rule out the endogeneity of caregiving hours. Our analysis revealed a negative association between caregiving and income for women that depended on a caregiving threshold of 63-hours per week. There was an absence of caregiving-income relationship among men. These results offer new insights into the opportunity costs of unpaid caregiving and support tailored policies to protect the financial well-being of female caregivers.
Biomedical Research During the COVID-19 Pandemic: Success in Sars-Cov-2 and Other Infectious Diseases
Authors: Osório Nuno S. , Veiga Maria Isabel
Published: February 2021

It is known for decades that viruses from the Coronoviridae family can adapt to human-to-human transmission. In 2020, SARS-CoV-2 caused a global pandemic of unprecedented scale imposing the loss of millions of human lives and being at the heart of a global economic crisis. Thus, we overviewed key research advances generated from the identification of the etiological agent to a better understanding of its origin, evolution and factors underlying global spread. Furthermore, we analyze the scientific productivity using the PubMed database. We found that the total number of publications increased more than 8% in 2020 when compared with 2019 or the average publications per year in the previous quinquennial. Remarkably, 86,638 publications related with COVID-19 and SARS-CoV-2 were published in 2020. Furthermore, there was also an increase in 2020 of publications in other major infectious diseases, such as AIDS, tuberculosis, or malaria. This success is likely the result from the vigorous, international, collaborative, and multidisciplinary response by the research community. During 2020 it was demonstrated, that with adequate support, it is possible to boost the rate of scientific progress in infectious diseases. Sustained investment in science will be key to address existing and future pandemics as the human population increases.

Published: February 2021

Concrete, as one of the essential construction materials is responsible for a vast amount of emissions. Using recycled materials and gray water can considerably contribute to the sustainability aspect of concrete production. Thus, finding a proper replacement for fresh water, in the production of concrete, is significant. The usage of industrial wastewater, instead of water in the concrete can is considered in this paper. In this study, 450 concrete samples are produced with different amounts of wastewater. The mechanical parameters such as slump, compressive strength, water absorption, tensile strength, electrical resistivity, rapid freezing, half-cell potential, and appearance are investigated. The results showed that the usage of industrial wastewater does not significantly change the main characteristics of concrete. Although, increasing the concentration of the wastewater can decrease durability and strength features nonlinearly.

Bats are reservoirs of many pathogenic viruses including the lyssaviruses rabies virus (RABV) and Australian bat lyssavirus (ABLV). Lyssavirus strains are closely associated with particular host reservoir species, with evidence of specific adaptation. Associated phenotypic changes remain poorly understood but are likely to involve P protein, a key mediator of the intracellular virus-host interface. Here, we examine the phenotype of P protein of ABLV, which circulates as two defined lineages associated with frugivorous and insectivorous bats, providing the opportunity compare proteins of viruses adapted to divergent bat species. We report that key functions of P protein in interferon/STAT1 antagonism and the capacity of P protein to undergo nuclear trafficking differ between lineages. Molecular mapping indicates that these differences are functionally distinct, and appear to involve modulatory effects on regulatory regions or structural impact, rather than changes to defined interaction sequences. This results in partial but significant phenotypic divergence, consistent with ‘fine-tuning’ to host biology, and with potentially distinct properties in the virus-host interface between bat families that represent key zoonotic reservoirs.

Among various metal-based nanoparticles, silver nanoparticles (AgNPs) manifest superior inhibitory effect against several microorganisms. In fact, the AgNPs based therapy has been reported to inhibit both sensitive as well resistant isolates of bacteria and other disease causing microbes with equal propensity. Keeping this fact into consideration, we executed bio-mediated synthesis of AgNPs employing Hibiscus rosa sinensis flower extract. The as-synthesized AgNPs were evaluated for their potential to inhibit Streptococcus mutans (S. mutans), one of the main causative bacteria for dental caries. Beside several other reasons, orthodontic appliances have also been reported to facilitate infliction of oral cavity with a range of microbes including S. mutans. To determine the growth inhibitory and anti-adherence activity of AgNPs on orthodontic appliance, we performed microbiological assays employing AgNPs adsorbed on to the orthodontic wires. Topographic analysis of orthodontic wires was executed by scanning electron microscopy. In addition to antimicrobial and antibiofilm activity against oral S. mutans, the as-fabricated AgNPs demonstrated significant inhibitory and anti-biofilm properties against other biofilm forming bacteria such as Escherichia coli and Listeria monocytogenes as well.

Composite materials are widely used in the dental field in clinics as biomaterials. For example, it has been used as a biomaterial to repair caries and restore masticatory function, and as a cement to adhere the restoration to the tooth substrate. In order to demonstrate its function, dental biomaterials are measured their mechanical strength. From such basic research, we explained the potential of dental biomaterials, especially flexural strength and modulus of elasticity. Mechanical properties of dental biomaterials similar to those of the tooth, thermal stimulation, and aesthetic elements in the oral cavity. In this part, we will introduce the commercialized products of composites suitable for the characteristics and tooth quality, and provide the reader with the characteristics from the flexural characteristics of the composite materials used in clinical dentistry. In clinical performance, it might be advisable to delay polishing when composite biomaterials are used for luting materials, filling materials and core build-up materials since improved the flexural strength and the flexural modulus of elasticity were displayed after 1-day storage. And it is thought that flexural strength or characteristics is a significant important mechanical property of oral biomaterials.

The utilization of eco-fonts for office printing is a sustainable, “green” printing concept, which has obvious economic benefits. As a result, it has a significant effect on environmental sustainability. This practice's fundamental problem is the decreased quality of text printed using eco-fonts compared to those printed with regular fonts. The aim of this research is eco-font efficiency estimation, i.e. determination of toner usage reduction level of inkjet-printed documents typed with this font type, as well as estimation of the extent humans perceive differences between text printed with eco-font and the one printed by its “non-eco“ equivalent. Combining the instrumental measuring method and digital image analysis, it was found that this simple principle (eco-font utilization) enables substantial toner usage reduction for an inkjet printing system. At the same time, a visual test showed that the visual experience of text printed using eco-font was sufficient. In addition, awareness of the benefits that eco-font utilization brings, change users’ attitude towards eco-font quality. The concept of removing the black pixel from this commonly used Thai font has a great potential for the sustainability printing process, and this simple solution could be applied to other languages as part of the GIT campaign.

This paper presents a detailed description of three methodologies to electrify the rural households of small loads with reliable and economical method using solar energy as input source of power. It is observed that high DC voltage is better and economical solution rather than AC based solar systems and low voltage DC systems. In this paper, three methodologies were analysed to select the right combination of portable converters with low prices, which may further enhance the energy access and affordability to common people. The proposed three methodologies were tested through action research in collaboration with a team of scientists and technical experts of National Institute of Solar Energy. The comparative analysis is carried out on three different converters, various kind of house loads and types of power supply i.e. AC/DC. The performance, quality and economic evaluation has been carried out with the help of MATLAB SIMULINK and other measuring instruments specific for solar photovoltaic systems. The derived results were analysed and inferences made for use in village household loads and their income groups. Further, a three-step analytical framework on village-level power energy efficient power at affordable power preposition was presented. This study will help in the designing as well as in the performance and economic evaluation of converters based on solar photovoltaic systems of different technologies.
Dark Matter on the Closed Region Connected With Black Hole by Wormhole
Authors: Bousder Mostafa
Published: February 2021

In this letter, instead of choosing the Einstein Rosen bridge between two black holes as in ER=EPR, we consider a wormhole between a black hole and a closed edge of the wormhole. We assume that information in a black hole travels through a wormhole, turns to mass (dark matter) in the closed region. This study is in contradiction with the existence of the white hole in our Universe. We replace the notion of the white hole with the massive closed region. We prove the metric of the closed region by the Hopf fibration, this new metric generalizes the $AdS_{5}$\ metric.
Simulating Drillstring Dynamics Motion and Post-Buckling State with Advanced Transient Dynamics Model

As drilling sections become deeper and longer, transferring more weight downhole to improve rate of penetration is the primary concern for the operator. Drillstring dynamics and buckling are some primary limiters for drilling efficiency. Aggressive drilling parameters may lead to severe downhole dynamics, which leads to cutter breakage and tool damage. When axial compression exceeds a certain threshold, the drillstring buckles sinusoidally inside the wellbore first, followed by helical buckling. Buckling leads to accelerated joint wear, tool fatigue failures, and lower drilling efficiency. To better manage drillstring dynamics and buckling, we propose a method of simulating drillstring dynamics motion and postbuckling state using an advanced transient dynamics model.

An analysis methodology was developed on the basis of the finite element transient dynamics model. The model captures the enriched physics of drillstring dynamics and loading: the large deformation of buckled drillstring, the strong nonlinearity of contact and friction forces, and the dynamically triggered instability caused by drilling rotation. Transient dynamics simulations are conducted for drillstring with the actual well trajectory and rotation speed. The weight on bit (WOB) is ramped up gradually, and the drillstring deformation is monitored to detect the onset of buckling or dynamics instability.

To conduct the model validation, the buckling inception loads predicted by the model are compared against the analytical equation of critical buckling loads. A field extended reach drilling (ERD) job was simulated by the model. The downhole weight and torque data from the measurement-while-drilling (MWD) tool was used to validate the weight transfer prediction by the model. Most existing buckling theories use the analytical equations of critical buckling load, which were normally derived on the basis of the idealized assumptions, such as perfect wellbore shape and uniform tubular geometry. The proposed method simulates the drillstring behaviors in the field drilling conditions and aims to capture effects of wellbore friction and string rotation. The transient dynamics model is capable of simulating drillstring dynamics movement (whirling and snaking) and weight lockup under severe helical buckling. An automatic method is proposed to interpret the drillstring behaviors from the simulation results. Using the transient dynamics model, the procedure presented in this article can simulate the dynamics and buckling behaviors of drillstring and help mitigate associated risks in well-planning and execution phases.
