Introduction: Health services during the Corona Virus Disease (Covid-19) pandemic will be very different from the situation before Covid-19, because Hospitals must prepare stricter security procedures where PPI protocols are followed according to standards. Patient admission procedures will certainly experience the impact of changes including the universal use of masks, stricter screening procedures, abolishing visiting hours, and restrictions on patient companions and even separation of services for Covid-19 and non-Covid-19 patients. This affects the performance of hospital employees, especially in the Emergency Room (ER). Employee performance is influenced by many factors such as leadership style and work environment. The purpose of this study was to analyze the correlation between leadership style and work environment with the performance of emergency room nurses at the hospital during the Covid-19 pandemic in 2022. Methods: This is an observational study with a cross-sectional approach. This research was conducted in the Emergency Room of Hospital Prof. dr. R.D. Kandou Manado in March-May 2022. The respondents to this study were 118 nurses. The variables in this study are leadership style, work environment and performance. The instrument used is a questionnaire that has been validated by researchers. Data analysis carried out in this study was bivariate analysis using the Chi-Square test.

The interrelation of literature and choreography in the ballets of John Neumeier “Death in Venice” and “Anna Karenina”
Authors:   Russian Institute of Theatre Arts (GITIS), Popova Kseniia V.
Published: June 2023

Interpretation of literary works of various genres is an important direction in the work of choreographer John Neumeier. His staging strategy is based on careful work with the literary text. The performances created by Neumeier are not just an illustration of the original plot, but show new angles of adapting classical literature into the form of a ballet performance. Thе article studies two of his productions: “Death in Venice” (2003) based on the novella by Thomas Mann and “Anna Karenina” (2017) based on the novel by Leo Tolstoy. The choice of these ballets was determined by the interest in researching the methods of choreographer’s adaptation of the literary texts that were not written to be staged. Neumeier brought “Death in Venice” closer to the world of ballet by the method of transferring the main character’s sphere of activity from literary to choreographic, which made it possible to visualize similar internal processes of creative activity. The ballet “Anna Karenina” was interpreted by the choreographer according to the current socio-cultural situation, which increased the emphasis on eternal themes in Tolstoy’s text. The analysis of the interrelation between the literary, musical and choreographic foundations of Neumeier’s performances makes it possible to reveal the main methods of his work with the literary source, to determine the features of the artistic thinking of the choreographer.
Modelling the Steady-State of Secondary Control in Islanded AC Microgrids
Authors: Pompodakis Evangelos , Karapidakis Emmanouel , Agundis Tinajero Gibran David
Published: June 2023

The secondary control is applied in islanded Microgrids (MGs), after the primary control, in order to restore the buses voltage and frequency to specified values. The existing power flow methods can accurately calculate the power flow for droop-controlled islanded MGs, but in many cases, they cannot calculate the steady-state solution of the MG after the action of secondary controllers. The main challenge in the steady-state modelling of the secondary layer lies in that the secondary controllers consist of integral parts, which can integrate functions with different integral histories, and therefore, under certain circumstances, can imply inaccurate power sharing between the distributed generation units (DGs). This phenomenon is most pronounced under communication failures, as will be shown in the simulations. In this way, this paper proposes a power flow method for calculating, accurately, the steady-state solution of hierarchically controlled islanded AC MGs, including droop-based primary control and secondary control. The paper includes four main features: a) generalized implementation in several communication strategies e.g., centralized, decentralized, consensus, distributed averaging, b) precise simulation of communication links and integral parts of secondary controllers, c) low computation time, and d) accurate 4-wire network representation. Simulations were executed to validate the proposed method against Simulink and to highlight the importance of an accurate modelling of secondary control in the power flow method for islanded MGs
Short Circuit Analysis of 72Ah Li-Ion Battery Storage with Four Battery Management Designs
Authors: Bansal Abhishek
Published: June 2023

This paper presents the simulated study of 72Ah battery bank, where the possibile causes of faults are analyzed  due to varying temp. conditions from 22º Celsius to 59º Celsius (71.6º F to 138.2º F), charging conditions, which can lead to short-circuit, potentially causing electrical shock, fire hazard, personal injury,property damage etc. Each cell is 3.7 V, 6.66 Wh,1800 mA.The system comprises of 400 cells in 40 parallel arrays with 10 cells in each array and four battery management system (BMS) designs were used in the simualtion. The short-circuit study has been divided into two fault categories. First one due to faults inside the design of battery management system (BMS) alone in which nine faults are studied where the simulation was run for 20 hours (72000 seconds) of simulation time for each of the nine fauts, that is 180 hrs or 648000 seconds of simulation time. The second fault cause is attributed due to mixed faults which comprises faults due to batteries in battery bank and due to faulty BMS which resulted in improper charging of the cells. Eleven faults are found in the second case, where again, the simulation was run for 20 hours (72000 seconds) of simulation time for each of the eleven fauts, that is 220 hrs or 792000 seconds. In total, the simulation study is of 1440 000 seconds or 400 hrs or 16.666 days. The data leading to this study and conclusions has also been uploaded. 
Modeled Impacts of Solar Forecast Error on Utility Production Cost
Authors: Hobbs William , Tresan Jenner , Kline Michael , Guha Mousumi , Duncan Brent
Published: June 2023

Solar forecast error can be represented in electric utility production cost modeling to assess impacts of uncertainty in different scenarios. We use reforecasts (a.k.a., historical forecasts, hindcasts) that were developed to be concurrent with synthetic solar generation profiles (matching each hour in the same year), along with asynchronous forecasts (i.e., with errors remapped from different hours and/or years), to explore impacts on model results. We demonstrate that production cost increases non-linearly with forecast error, and that our method for remapping asynchronous forecast errors to a solar generation profile produces results that are similar to the concurrent forecasts, but with about 20\% lower cost impacts due to forecast error.
Analysis of the 2007-2008 Hérault premiumized grubbing-up campaign: a tool to better understand Fischer-Boel’s 2008-2011 grubbing-up campaigns and the desire in 2022 to reintroduce locally premiumized grub-ups

Published: June 2023

The objective of this article is to study the microeconomic motivations of the grubbing up of vines by analyzing of application files and a survey in a department in the south of France, Hérault, the year before the 2008/2009 campaign, which implements the European grubbing up program of 175,000 hectares of vines. Only one French department and one campaign are evaluated: Hérault and 2007/2008. Our originality is the analysis of a subset consisting of 341 Viniflhor applications for grubbing up premiums, which represents 20% of all beneficiaries receiving premiums. The applications were later sent with the applicants’ consent to a development agency. Within this subset, we selected 51 grape growers with whom we conducted a qualitative and quantitative survey. Our goal was to identify their real motivations for grubbing up their vines. We first undertook a historical review of Europe’s grubbing up policy and of older research analyzing in detail this question such Pierre Bartoli’s 1982 thesis. We also included studies of the Observatoire de l’Hérault (Dyopta) that take into account experts’ opinions and statistical viewpoints. This review enables us to present the main indicators that let us “objectively” analyze these grub ups. We then put forward synthesized results explaining the qualitative interviews. Altogether they confirm the goals of the European Commission that were to incite non-profitable older grape growers, working on small land lots to grub up the entirety of their farms. But joined to the aforementioned are many other farms that grubbed up only a small fraction of their vineyards mainly to cash in on the premiums in times of a dire wine crisis. Grubbing ups of young “improving varietals” reinforces this analysis.
Dust Exposure and Lung Function Disorders
Authors: Lestari Mona , Fujianti Poppy , Novrikasari Novrikasari , Nandini Rizka Faliria
Published: June 2023

Dust is a particle floating in the air produced due to mechanical processes such as splitting, grinding, grinding, punching or blasting, cutting and destroying material. Dust particles in the air for a relatively long time can enter the human body through breathing. Dust less than 5 µm entering the human respiratory system can reach the inside of the lungs or alveoli can cause lung function disorders. Impaired pulmonary function is the inability to develop (elasticity) of the lungs as well as disorders of the respiratory tract both structural (anatomical) and functional which causes slowing of respiratory airflow. The International Labor Organization (ILO) defines pulmonary dysfunction as the accumulation of dust in the lung tissue and lung tissue reaction to the dust accumulation. Dust entering the alveoli can cause hardening of the tissue (fibrosis) and if 10% of the alveoli is hardening, it will reduce its elasticity in accommodating the volume of air so that the ability to bind oxygen is decreased. This condition causes a reduction in the supply of oxygen absorbed by blood capillaries to the brain tissue, heart, and other body parts.
Gotta Get Those Ill-Gotten Gains: Improving the FTC's Authority to Seek Disgorgement in Antitrust Cases
Authors: Buggs Kathryn
Published: June 2023

Disgorgement is an equitable monetary remedy that requires a defendant to give up all ill-gotten gains from their illegal conduct. Unlike damages, which can be compensatory, deterrent, or even punitive in nature, disgorgement focuses primarily on deterring future illegal conduct. It relies on the simple moral premise that wrongdoers should not be allowed to retain the profits of their wrongdoing. Especially in antitrust litigation involving complex, multilayered supply chains, damages can underestimate the true harm suffered as a result of anticompetitive conduct. Disgorgement, if calculated properly and litigated thoughtfully, has the potential to provide redress for the full amount of harm and therefore act as a more efficient deterrent.

Federal and state antitrust enforcers have sought disgorgement for anticompetitive conduct with limited success, and a recent Supreme Court decision casts doubt on the Federal Trade Commission’s authority to seek disgorgement altogether. Still, there is bipartisan support in Congress and the White House to restore the FTC’s disgorgement authority. This Note proposes enacting legislation to that effect, including a provision that would allow state attorneys general or private plaintiffs to seek disgorgement on the FTC’s behalf (called a “qui tam” provision). Further, this Note outlines how leveraging existing litigation tools can alleviate concerns that disgorgement will lead to duplicative recovery. By restoring the FTC’s authority to seek disgorgement and creating a qui tam mechanism for private enforcement, antitrust plaintiffs will benefit from increased leverage, enabling them to both recover the totality of harm caused by anticompetitive conduct and deter such conduct in the future.

Introduction: Hajj is a worship that is dominated by physical activity, so it is very important for a pilgrim who will perform the pilgrimage to ensure that he is ready and physically fit in addition to spiritual readiness.

Methods: A cross-sectional descriptive study was conducted on 720 data of prospective pilgrims from 5 embarkations (Sumatra, Central Java (DIY), East Java, Makassar, and Pondok Gede) which were taken using randomized sampling method.

Results: In this study, it was found that the age distribution of prospective Hajj pilgrims was mostly over 60 years old, able to carry out activities of daily life well (85%) independently. Most of the subjects needed assistance during mobilization (91%) although their cardiorespiratory endurance showed good results (above 4 METS).

Conclusions: This study indicates the possibility of musculoskeletal disorders in most of the subjects that hinder independence in the mobilization. Therefore, it is important to check the function before performing the pilgrimage, so that a rehabilitation program can be carried out and the determination of the right tools so that the implementation of the pilgrimage can be carried out optimally. Guidance on aspects of the functional ability of prospective pilgrims during the waiting

Published: June 2023

An analysis of the currently used algorithms and programs for assessing the static stability reserve of electric power systems (EPS) is carried out, which make it possible to build the boundaries of stability and calculate the sensitivity coefficient of all generators of the power system, which speeds up the process of selecting the settings of automatic excitation regulators (AER) and increases the visibility of the calculation results. On the example of the well-known in the theory of automatic regulation "Butterworth's rule", a qualitative analysis of the transient process in the control system in the presence of optimal stochastic AER is given and it is proved that the method of synthesis of optimal stochastic systems allows, under conditions of real limitations, to more accurately and qualitatively build regulators that provide the necessary stabilization accuracy.

Community consumption power in the use of electricity resources is growing very rapidly. This is because the power source is the main need for the community. Without electricity, daily needs cannot run smoothly. In various regions, especially Kediri, where the needs are changing, it is necessary to predict and provide electricity to meet the consumption needs of the people. There are many things that can be done to predict the need for electric power, one of which is forecasting. Forecasting methods that can be used include trend and Monte Carlo Simulation. The results of this study indicate that Monte Carlo simulations are better at predicting long-term electrical power requirements at ULP3 Kediri. Long-term electricity demand can be predicted with the equation: Yt =138691 + 6709 x t + 231 x t2. The results of the research can help PLN UP3 Kediri to provide electricity for consumers.
Role of an adaptor protein human germinal center-associated lymphoma (HGAL) in cell signaling and lymphomagenesis
Authors: Jiang Xiaoyu , Lossos Izidore S.
Published: June 2023

Human germinal center (GC)-associated lymphoma (HGAL) is a multi-domain adaptor protein expressed in GC B lymphocytes, T follicular helper (Tfh) cells and lymphomas derived from these cells. HGAL expression is an independent predictor of longer survival of diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin’s lymphoma (HL) patients. HGAL regulates B cell receptor (BCR) signaling and immunological synapse formation by binding to either the downstream effectors [e.g., spleen tyrosine kinase (Syk)] or other signaling regulators [e.g., growth factor receptor-bound protein 2 (Grb2)]. HGAL regulates the cytoskeleton that reshapes B cell morphology during BCR signaling and cell motility by at least two molecular mechanisms: enhanced Ras homolog gene family member A (RhoA) signaling and inhibition of myosin-actin translocation. These effects on the cytoskeleton decrease lymphoma dissemination in animal models and contribute to decreased lymphoma dissemination in patients. The latter may contribute to the association of HGAL protein expression with longer survival of patients with DLBCL and HL tumors. The ability to regulate multiple and distinct functions simultaneously in B cells implies that the HGAL protein level is tightly regulated. It was demonstrated that HGAL can be regulated by PR/SET domain 1 (PRDM1)/B lymphocyte-induced maturation protein-1 (BLIMP1) and interleukin-4 (IL-4) at the transcription level, by microRNA-155 (miR-155) at the post-transcriptional level, and by F-box protein 10 (FBXO10) at the post-translational level. Constitutive enforced expression of HGAL at physiological levels leads to lymphoid hyperplasia and DLBCL in mice. Future studies need to focus on identifying HGAL interactome, dissecting its interaction network, and understanding HGAL spatiotemporal signaling in live cells in physiological conditions. Further, the recent demonstration of HGAL expression in Tfh cells requires the determination of its function in these cells. These studies will contribute to new insights into the biology of these cellular subsets and how immune dysregulation contributes to lymphomagenesis.
Mesenchymal stem cell stroke therapy: current limitations in its clinical translation
Authors: Pastorello Ylenia , Slevin Mark
Published: June 2023

For more than a decade now, research studies, proof of concept work, and clinical trials have endeavored to understand how mesenchymal stem cells might be used to help protect, repair, and/or regenerate damaged brain tissue following stroke. To date, the majority of studies have not demonstrated significant improvements in either morbidity or medium-long-term outcome, although safety has been relatively well proven. Limitations are likely to be linked to the pathobiological complexity and seriousness of stroke tissue damage, low efficacy of treatment, and short half-life of bio-active proteins released by stem cells. This article will highlight the heterogeneity and limitation of completed studies and the current status of ongoing work. At the same time, the potential of other combinational type treatments, such as drug-loading and targeting, and the use of hydrogels is discussed.
Application of Splines of the Seventh Order Approximation to the Solution of the Fredholm Integral Equations with Weekly Singularity
Authors: Burova I. G. , Alcybeev G. O.
Published: June 2023

We consider the construction of a numerical solution to the Fredholm integral equation of the second kind with weekly singularity using polynomial spline approximations of the seventh order of approximation. The support of the basis spline of the seventh order of approximation occupies seven grid intervals. In the beginning, in the middle, and at the end of the integration interval, we apply various modifications of the basis splines of the seventh order of approximation. We use the Gaussian-type quadrature formulas to calculate the integrals with a weakly singularity. It is assumed that the solution of the integral equation is sufficiently smooth. The advantages of using splines of the seventh order of approximation include the use of a small number of grid nodes to achieve the required error of approximation. Numerical examples of the application of spline approximations of the seventh order to solve integral equations are given.
A Prescrição em Face da Autonomia do Direito de Agir: Abordagem Histórico-Dogmática
Authors: De Castro Fiuza César Augusto , Ribeiro Regina
Published: June 2023

O presente artigo tem como objetivo fazer uma releitura da incidência da prescrição em face da autonomia concedida ao direito de agir. Até a promulgação do Código Civil de 1916, era adequada a afirmação de que a prescrição incidia sobre a ação ou sobre a pretensão, pois vigia a teoria processual do direito concreto de agir. Contudo, com a aplicação da teoria do direito abstrato de agir pelo atual Código de Processo Civil, a pretensão do autor passou a ser autônoma e independente em relação ao direito material pleiteado. Consequentemente, o que passa a se extinguir pela prescrição é a responsabilidade do devedor, não mais a ação ou a pretensão do autor. Para corroborar esta conclusão, avalia-se, também, a origem histórica do termo pretensão no Direito Comparado, bem como a sua tradução do alemão para o português, oportunidade em que restou demonstrado que é inadequada a afirmação de que a prescrição incide sobre a ação ou a pretensão do credor, devendo recair sobre a responsabilidade do devedor.
Desarrollo Rural y Ordenamiento Territorial. Entre la Normativa Nacional y la Normativa de la Provincia Argentina de Santa Fe
Authors: Malanos Nancy L.
Published: June 2023

Argentina ha emprendido, desde hace varios años, el ordenamiento rural de su territorio, otro tanto han hecho las provincias en sus respectivas jurisdicciones. Esta tarea, que se demuestra a través de su normativa, se enlaza con el desarrollo rural que en los distintos ámbitos busca una mayor equidad social, sustentabilidad ambiental y competitividad integral y armónica. La agricultura moderna y multifuncional se inserta, complementándose, con el nuevo paradigma que deja de lado la visión parcializada del territorio para presentarlo como un todo. La provincia de Santa Fe, una de las provincias que integra la zona núcleo de la región pampeana del país y cuya legislación en materia de ordenamiento nos proponemos analizar sucintamente, no es ajena al paradigma del enfoque territorial.
