Authors: Keener Myles , Sturges Rebecca , Becker Kathryn , Gifford Connor , Alexander Christopher , Schroeder Jason , Smithason Saksith
Published: November 2021

Documentation status is a well-recognized social determinant of health in the immigrant population of the United Sates. Lack of financial means and fear of legal repercussions can delay medical attention, limit treatment options, and decrease patient follow-up. This is reinforced by current government policies that limit financial assistance in emergency situations and deny coverage of preventative or follow-up care. Here we report a case of an otherwise healthy 24-year-old undocumented immigrant who presented to a rural United States emergency room with new-onset seizure, blurry vision, and headache. The patient was admitted to the neurosurgical service where he was diagnosed and treated for a symptomatic arachnoid cyst. Here we review current healthcare legislation that restricts access to preventative and follow-up healthcare in the United States. This case highlights the ways in which the undocumented immigrant patient population remains negatively impacted by these policies, often leading to late presentation and limited neurosurgical treatment options.

School and school gym buildings represent a relevant potential for construction of photovoltaic panels, to be integrated into roofs of these buildings. Given that roof structures are passive, construction of photovoltaic systems does not interfere with the building functionality, does not it in any way adversely affect the environment. Installation of photovoltaic systems on building roofs brings the production and consumption of electricity closest possible, therefore such systems ensure significant reduction in power losses in transmission and distribution grids. In addition to locally produced electricity, construction of photovoltaic systems on the school buildings’ roofs produces an educational effect as well. By installing a measuring and acquisition system which would include the measuring data on the photovoltaic power plant production parameters and school electricity consumption into school labs, technology would be closer to students, as well as possibilities to meet the demand for electricity from this basic renewable energy source. This paper presents the results of evaluations of the available roof surfaces of school buildings in Serbia for the photovoltaic panels installation. For each category of school building, an estimate of possible annual production per unit of average roof area was made. Summarizing all the results, estimates of possible installed capacity and annual electricity production for different scenarios are given.

At a time when we are facing various meteorological disasters on a daily basis and when their effects are already noticeably affecting economic development, the action to mitigate them becomes a major topic and the backbone of many countries' strategic planning. As increasing the use of renewable energy sources is one of the main mechanisms in this action, the analyses of the possibilities of applying the available technical achievements, which could further increase the utilization potential of these energy sources, represent not only a need but also a professional duty. Because of that, and since Serbia possesses large quantities of so-called low temperature thermal energy which cannot be converted into electricity in the conventional manner by means of water-steam plants according to Rankine-Claus cycle, in this paper attention is paid to the operation of so-called power plants which can do so and which operate according to the so called Organic Rankine and Kalina cycle. In addition to the presented modes, a thermodynamic analysis of their operation was performed and their potential for application was compared and analysed through a display of changes in the rate of efficiency.

This paper presents a new algorithm for three-winding transformer protection against internal short circuits. The algorithm is based on the application of the digital phase comparison of currents measured at the primary, secondary and tertiary terminals of the power transformer. The applied digital phase comparison does not calculate the angle between the two currents compared in phase, but uses the method of integration of the product of two signals within one basic semi-period of the signals. In order to provide selective protection in the case where the power transformer has only one of its three windings connected to the active network and the other two windings feeding passive networks, an overcurrent function has been added to the digital phase comparator. The paper shows that the application of the new algorithm can successfully detect the internal faults of the three-winding transformer and ensure timely tripping of protection. The signals obtained by computer simulations were used to verify the operation of the proposed algorithm. The algorithm and test results are given in the paper. Index Terms- power system protection, power transformer, digital phase comparison, fault discrimination.

in 2018 the first connections of wind farms to the transmission network EMS have been realized. In a short period of time, the total of four (4) wind farms were put into operation and, therefore, with engaging a lot of employees, it was necessary to modify and adapt a number of procedures and regulations in order to conclude all the Wind Energy Exploitation Agreements. Due to the stochasticity of the wind phenomenon, the forecast of wind farm production and its relation to the achieved energy production shall be addressed. As the employees of JSC EMS meet for the first time with this type of production capacities, the paper contains real data on meteorological parameters that influence the production of electricity from wind farms. Since all four (4) wind farms are located in the same geographical area, their impact on power flows, operational planning and balancing of the electrical power system shall be analyzed.

Effects of Mismanagement of Medical and Plastic Waste in Pre and During COVID-19 Outbreak
Authors:   Suankularb Wittayalai School, Bangkok, Thailand, Thutsaringkarnsakul Thanapat
Published: November 2021

Many countries already have problems with waste management, but when the COVID-19 outbreak happens, the existing problems are worsened. This review aims to examine how mismanagement of medical and plastic waste affects the environment and people, especially those who work in healthcare facilities. Prior to the COVID-19 pandemic, it was clear that the majority of issues stemmed from mismanagement of plastic waste. For example, plastic waste can be seen in various places, such as the deepest oceanic floor, The Mariana trench, which is proved by microplastics found in amphipods’ digestive tract living down there. Apart from environmental effects, the economy is also affected by plastic pollution as the tourism business has decreased in Korea and USA due to the increasing amount of plastic waste. While normal plastic waste can largely affect society, medical wastes seem to pose more severe consequences as medical wastes might be contaminated, pathologic, and radioactive. However, during the pandemic, the usage of both medical and plastic waste has increased in general. Mismanaged waste also carries COVID-19 like other pathogens, and the virus can survive on it for a long period of time, making any mismanaged waste a risk factor. Incinerated ashes from medical waste used for fighting the virus can also cause pollution as they contain heavy metals. In conclusion, mismanaged plastic waste mostly affects the environment, while mismanaged medical waste might carry harmful pathogens, including the COVID-19, putting people at risk. More actions need to be done to improve the effectiveness of waste management procedures.

Random Effects Endogeneity: A Variable Pretest
Authors: Kunce Mitch
Published: November 2021

Abstract

The appealing but complex Hausman and Taylor (1981) random effects
(instrumental variable) estimator requires prior knowledge that certain explanatory
variables in a panel are uncorrelated with the latent group effects. The purpose of
this examination is to outline a tractable variable pretest that facilitates the initial
sorting of regressors as likely exogenous or endogenous. The variable pretest
proposed herein builds on the pretest estimator suggested by Baltagi et al (2003) by
providing the necessary foundation for regressor identification. Extensions are
suggested for the two-way error components construct.

Keywords: Panel data, Random effects, Variable pretest, Hausman-Taylor.

Democratisation of Business How More Democratic Business Structures Generate Innovation
Authors: Faix Anna-Vanadis
Published: November 2021

Democratisation is a topic that is increasingly finding its way into the economic debate and is also becoming more and more of a trend within companies. The debates reveal various advantages and disadvantages of democratising companies. Within the various models of democratisation of companies, however, there seems to be a lack of coherent integration of the theoretical integration of this into the broad corporate structures – at least within business perspective. These often refer to orthodox theoretical foundations of hierarchical structures and corporate orientations, which in principle oppose and partly run counter to various forms of democratisation. In the present contribution, minimal conditions are to be worked out on the basis of democracy as cooperation and applied to the most elementary corporate structures. In such a coherent orientation and embedding, it can be shown that disadvantages of democratisation in the corporate context can be reduced and innovation and thus competitiveness can be promoted in a multidimensional way.

Terhelő örökség : Az iráni gazdaság lehetőségei és kihívásai a 2021-es elnökválasztás után
Authors: Fórián-Szabó Viktor , Kovács Tamás
Published: November 2021

Irán a 2021-es elnökválasztás után az 1979-es iszlám forradalom óta az egyik legnagyobb kihívással néz szembe. A gazdasági szankciók, a küszöbön álló vízválság és a világjárvány komolyan próbára teszik a fejlődő ország gazdaságát. A jelenlegi válságok kezeléséhez döntő fontosságú lesz, hogy Teherán hogyan helyettesíti az olajjövedelmet stabilabb bevétellel, és hogyan teszi hatékonyabbá a gazdaságát. E kérdések tekintetében elemeztük a 2008-ban megkezdett iráni privatizációs folyamatnak a gazdasági szektorokra vonatkozó hatásait. Arra a következtetésre jutottunk, hogy összességében a reformok szükségesek és eredményesek voltak, mivel növelték az állami jövedelmet, jelentősen hozzájárultak a gazdaság bővüléséhez, és csökkentették az országnak az olajtól való fiskális függőségét. A reformokat azonban találomra hajtották végre, a külföldről másolt politikákat úgy alkalmazták, hogy a döntéshozók nem vették figyelembe Irán gazdasági és társadalmi valóságát. Ezért a reformok többé-kevésbé „félúton” megragadtak.

Layered double hydroxides from aluminum saline slags applied in adsorption and photocatalysis processes for the removal of emerging pollutants
Authors:   , Santamaría Arana Leticia
Published: November 2021

The objective of the work studied here was to synthesize Layered Double Hydroxides (LDH) with aluminum extracted from saline slags and test their function once calcined into adsorbents/catalysts for use in the removal of emerging contaminants (pharmaceutical compounds) from aqueous media.Two different techniques for the removal of contaminants were tested, adsorption and photocatalysis. In the present work, a new procedure for the recovery of aluminum present in saline slags generated during the secondary recycling processes of aluminum as adsorbent/photocatalyst of diclofenac and salicylic acid, as examples of emerging contaminants, has been reported. Results obtained have been extensively analyzed throughout the present study.
An integrative, multidisciplinary approach to the study of the impact of climate change on legume agro-physiology and metabolism
Authors:   , Soba Hidalgo David
Published: November 2021

The leguminosae are second to cereal crops in agricultural importance based on area and total production, covering 14% of the cultivated land. Within the current and near future context, legume production is threatened by various abiotic stresses associated with climate change, which are expected to increase in number and severity during the following decades. Due to the important challenge to food security, it is important to understand how future legume crops can be bred to withstand adverse environmental conditions. The overall aim of this thesis is to gain further insights on the mechanisms involved in legume response to environmental conditions ([CO2], drought and temperature) through the integrated investigation of biomass, physiological and biochemical processes and the levels of metabolites and other compounds of the plants.
El compromiso escolar de estudiantes de bachillerato en el contexto de aprendizaje en línea
Authors: Zamudio Elizalde Pedro Damián
Published: November 2021

El compromiso de los estudiantes con la escuela es un tema educativo de interés actual. No obstante, las investigaciones sobre este objeto se centran en la validación de instrumentos cuantitativos que dan cuenta del compromiso, dejando de lado las experiencias vividas por los estudiantes en un contexto determinado. El presente estudio analizó el compromiso escolar de estudiantes de Cecyte, Baja California, en el contexto de aprendizaje en línea producto de la contingencia sanitaria. Desde un enfoque cualitativo se aplicó un cuestionario y se desarrollaron grupos focales y entrevistas con estudiantes de bachillerato. Los resultados apoyan el constructo multidimensional del compromiso escolar descrito en la literatura. Por una parte, los estudiantes se esfuerzan y cumplen con las indicaciones del profesorado, no obstante, la dificultad para asistir y participar durante las sesiones de aprendizaje en línea disminuye el compromiso conductual. Por otra parte, los estudiantes desarrollaron estrategias de aprendizaje que les permitieron comprender conceptos con mayor profundidad fortaleciendo con ello el compromiso cognitivo. Finalmente, el contexto educativo actual favoreció la emergencia de emociones negativas como el estrés, la frustración y la tristeza, las cuales impactaron en el compromiso afectivo.
Escuelas cerradas, aulas abiertas: estrategias de enseñanza remota en una comunidad rural de Yucatán
Authors: Marín Che Armando Josué , Pinto Sosa Jesús Enrique
Published: November 2021

El objetivo de esta investigación fue conocer el proceso de comunicación y las estrategias de enseñanza remota que han implementado los profesores de una escuela telesecundaria al sur de Yucatán durante el cierre de las escuelas en el ciclo escolar 2020-2021. Desde un enfoque cualitativo y multidisciplinar, se llevó a cabo un estudio de caso de tipo instrumental con orientación fenomenológica que nos permitió conocer con mayor precisión las experiencias, logros y retos de sus estrategias. La información se recuperó a través de entrevistas a profundidad a los docentes de la escuela, la revisión de evidencias de los profesores, así como de la observación de las clases virtuales, de la comunidad y de las reuniones escolares presenciales realizadas durante ese periodo. Los resultados revelan la necesidad de proponer estrategias didácticas contextualizadas que tomen en consideración la diversidad étnica y socioeconómica de las comunidades, así como las desigualdades sociales de las poblaciones y sus integrantes dentro del marco de la emergencia educativa y sanitaria.
