Increasing photovoltaic self-consumption for objects using domestic hot water systems
Authors: Shavolkin Olexandr , Shvedchykova Iryna , Kolcun Michal , Medved Dusan , Mazur Damian , Kwiatkowski Bogdan
Published: September 2024

The technique of estimating the expected decrease in electricity consumption from the grid and using PV energy for the taken load schedule based on archival data for 5 years is refined. With full self-consumption (SC), the reduction of consumption from the grid can be increased by 9.5%–30.7% for a year according to the rated PV power. Consumption should increase when PV generation exceeds a certain value. A discrete time control of the power of an electric storage boiler (ESB) is proposed based on the deviation of the storage battery (SB) state of charge from a given schedule with a heating concentration during hours of high PV generation. In the considered application, it is possible to increase SC by up to 21%. Reducing the load in the evening allows us to use SB energy to reduce consumption from the grid at night. The possibility of complete photovoltaic SC when the ESB is used with an air conditioner is substantiated. Limitations for air conditioner energy consumption according to PV generation are determined. The system’s 24h model of energy processes is supplemented with a thermal model. The standard use of ESB with water temperature maintenance was also considered for comparison. ESB power control allows you to reduce daily energy consumption from the grid by 1.7–2 times. When combining an adjustable ESB with an air conditioner, it is possible to reduce consumption from the grid by 1.466–1.558 times at minimum and increase consumption from the grid by 2–5% at maximum air conditioner consumption.
Dual Second Order Generalized Integrator – Phase Locked Loop technique applied to a distorted grid-connected solar energy based on a Z-Source Inverter
Authors: Daoudi Ali , Benalla Hocine , Nebti Khalil
Published: September 2024

In this paper, a Dual Second Order Generalized Integrator_Phase Locked Loop (DSOGI_PLL) technique applied to the Photovoltaic (PV) system supplying a Z-Source five-level Inverter (ZSI) is presented. The ZSI assures the increasing voltage of the PV system and provides the desired output DC at the input of the five-level Neutral Point Clamped Inverter (5L_NPCI), without any control which reduces the complexity of the overall system, this is due to the impedance network in its structure. We use Z-Source in order to eliminate the controlled DC bus as well as the use of the DC-DC Boost converter as an intermediary. A DSOGI technique is employed to control and optimize the energy quality, especially in distorted grid conditions and allows one to obtain a very low value of Total Harmonic Distortion (THD) which means lower peak currents, and higher efficiency. Low THD is an essential feature in power systems that international standards such as IEC 61000-3-2, and IEEE-519 set limits on the harmonic currents of various classes of power equipment connected to a distorted three-phase grid. Compared to the classic structure of inverters, the NPC five-level inverter presents a very high performance.

Authors: Hotlos Agnieszka , Boczkal Grzegorz , Karpinski Marcin
Published: September 2024

Mechanisms of contact diffusion during relay-contacts operation were investigated. The contacts with the same geometry but different chemical composition were tested. The 1st relay-contact in a pair was made of copper, and the 2nd had a surface coated with a layer of silver about 500 micrometers thick. Different numbers of work cycles ranging from 8.5 k to 550 k were applied. AC current in the system was limited to 5 A. The closed/open periods were set at 250/250 ms. The resistance of the contacts was measured every 100 cycles. The microstructure of the working surfaces of the contacts after different numbers of operating cycles was investigated. On the surface of Cu contacts eutectic precipitates are formed and on the complementary bimetal contact tiny Cu-rich precipitates were generated on the silver surface. Crossection observations showed mutual material diffusion between the contacts. The depth of silver diffusion into the copper contact after 550 k operating cycles reaches 30 micrometers. The resistance of the contact system was stabilized after 40 k cycles at a level of 0.25 Ohm.
Optimal control of a doubly fed induction generator of a wind turbine in cooperation with weak and rigid grids
Authors: Gołębiowski Marek
Published: September 2024

In this article a control method for a rotor side converter (RSC) of a doubly fed induction generator of a wind turbine is developed. The doubly-fed induction generator (DFIG) system of a wind energy power plant that improves grid symmetrization was applied. The issue of optimal control was treated as an extended linear quadratic regulator (ELQR) having an extra set of exogenous inputs, which are source voltages of the electric grid. No additional knowledge of equations modelling the exogenous inputs was assumed. The proposed method is much more efficient than the currently available linear quadratic control methods. The control objective for a weak grid was to maintain the given value of the voltage module on load terminals and the given value of active power transferred from the stator’s winding. First harmonic components of relevant waveforms were used for this purpose. This task also required the DFIG system to provide reactive power to the grid. In the case of a rigid grid, this reactive power would be too high. Therefore, in this case, it was assumed that the system would supply only part of the required active and reactive power, based on its capabilities. It was required that the voltage and current ratings of the system, mainly the DFIG, were not exceeded. Therefore, the parameters of the network in these difficult failure cases were corrected only partially. The behaviour of the grid in the conditions of failure, as well as the return to the steady state after failure disappearance, were studied.
Minerals of antimony: a newly found occurrence in the Karkonosze granitoid pluton and a review for Lower Silesia, Poland, with general background
Authors: Kozłowski Andrzej , Marcinowska Agnieszka
Published: September 2024

The article describes assemblages of ore minerals of the size of tenths to a few millimetres, which occurred in small quartz veinlets and nests in 10 previously unknown sites. This mineralization was found in the north-eastern part of the Karkonosze granitoid pluton at the southern slope of the Wysoki Grzbiet (High Ridge) in Izera Mts. The studies concerned mainly 18 Sb minerals: antimony, Sb-bearing domeykite, getchellite, stibnite, willyamite, berthierite, boulangerite, bournonite, chalcostibite, falkmanite, famatinite, geocronite, robinsonite, semseyite, tetrahedrite-(Fe), cervantite, kermesite and schafarzikite; seven of them have been found in Poland for the first time. The parageneses, morphological features, XRD data and chemical composition of the Sb minerals are presented. Fluid inclusions in quartz adhering to the Sb minerals had generally homogenization temperature (Th) 108–341°C and total salinity ΣS 4.6–10.1 wt. %. The inclusion fluids were of the NaCO3- Ca(HCO3)2-NaCl-KCl type with minor F and S, and occasional CO2 presence. The parent granitoid contains Sb in trace amounts (0.18–0.36 ppm) and the rock was possibly a source of this (and other) element(s) for the ore minerals. Migration of meso-epithermal solutions with Sb etc. was probably stimulated by local reduction of pressure during the formation of fissures and cracks in granite, next filled by quartz with ore minerals. The features of the historical process of the recognition of Sb ores and previous studies of the minerals investigated in this research are included in the presentation and discussion. Special attention was paid to the listing of the occurreences of Sb minerals in Lower Silesia with appropriate references.
Fixed Switching Frequency Model Predictive Control and Passivity Based Control for DC-DC Converter
Authors: Zhang Yajing , Shen Yuqing , Huang BaoYing , Zhang Jiangchao , Chang Haojing
Published: September 2024

The DC-DC converter represents a crucial component in the renewable energy sources. The stability and dynamic capability enhancement of the DC/DC converter have emerged as a significant research topic in the current era. Model predictive control (MPC) is particularly prevalent due to its high dynamic response speed, simplicity of the controller design, and capacity for multi-objective optimization. However, the traditional finite control set model predictive control (FCS-MPC) method is suffer to variable switching frequency and vast computing. To improve the dynamic performance of the converter, a novel nonlinear control strategy named fixed switching frequency MPC and passivity-based control (PBC), named FSFPBMPC, is proposed, which could achieve fixed switching frequency and enhance the system's dynamic response speed. Firstly, the Euler-Lagrange (EL) model of the boost converter is established. Secondly, the relationship between duty cycle and MPC is established. Ultimately, the output voltage of PBC is incorporated into the cost function of the FCS-MPC. The characteristics of PBC power shaping and damping injection can enhance the system's immunity to interference, improve the system's dynamic response speed, and thus reinforce the system's stability. Then, depending on MATLAB, the simulation results proved that the proposed strategy has the same effect as we expected.
Characteristics of solution to singular fractional differential equation with two Riemann-Stieltjesdintegral boundary value conditions
Authors: Zhang Nan , Zhang Lingling , Liu Hongwei , Wang Hui , Tian Huimin
Published: September 2024

The purpose of this paper is to study unique solution and iterative sequence of approximate solution for uniformly approaching unique solution to a new class of singular fractional differential equations with two kinds of Riemann-Stieltjes integral boundary value conditions by using some fixed point theorems. Because of different properties of the nonlinear terms and complexity of the boundary conditions in equations, we first probe several fixed point theorems of sum-type operators which expand many existing works in this research area. It is essential to point out that some conditions in our works greatly simplify the proof process of fixed point theorems. By applying the operator conclusions obtained in this paper, some sufficient conditions that guarantee the existence and uniqueness of solutions to singular differential equations are obtained, two iterative schemes that uniformly converges to the unique solution are given which provide computational methods of approximating solutions. As applications, some examples are provided to illustrate our main results.

The problem facing an energy sales company is the collection of overdue accounts receivable (RA). The valuable achievements that energy sales companies have achieved while working to debtors are constantly being improved. So, specialists in working with remote control of an energy sales company need to make attempts to resolve the situation and search for compromises. It can be concluded to reduce the costs associated with work on managing debt, it is necessary to segment consumers according to the degree of possibility of debt collection and develop tools for interacting with consumers. It is proposed to partially solve the problems of accounts receivable by introducing an energy resource consumer profile. The research base is 703,726 telephone calls from operators with debtors of an energy sales organization. We grouped subscribers into 4 synonymous directions after we studied the subscriber's answers: Forgetful, Aggressive, With a special social status, Not available. We used the sorting method, the comparison method and the logical method. The operator’s work must be unified in order to sort subscribers according to the above principle at minimal cost. A standardized interview was developed for this purpose. The effectiveness of the proposed measures was manifested in the reducing labor costs and the increasing operator productivity. The importance of using a questionnaire survey allows employees to direct free energy and time to other operational tasks.

Published: September 2024

This study explores the impact of audit delay, the size of public accounting firms, audit opinions, and management changes on auditor switching among companies listed on the Indonesia Stock Exchange. The research aims to identify the key factors that influence a company's decision to switch auditors. Using logistic regression analysis and secondary data from financial reports, the study introduces a unique approach by simultaneously analyzing four independent variables, which is rarely done in prior studies. The results reveal that audit delay and management changes significantly affect auditor switching, while the size of public accounting firms and audit opinions do not have a significant impact. The findings suggest that operational and managerial factors play a more critical role in auditor switching decisions compared to financial factors. Theoretically, the study supports the relevance of agency theory in explaining auditor switching, particularly in addressing conflicts of interest between management and shareholders. Practically, these results provide valuable insights for company management when deciding to switch auditors and highlight the importance for regulators to implement policies that enhance transparency and audit quality, strengthening corporate governance practices in Indonesia.

The Dark Side Of Fast Fashion: Examining The Exploitation Of Garment Workers In Bangladesh
Authors: Gunawan Yordan , Matahariza Anandiva , Putri Wiwit Kharisma
Published: September 2024

There have been several attempts to decrease the usage of fast fashion, but no one has been able to stop its development. We are aware that fast fashion is a business model that imitates the most recent catwalk trends, has evolved into high fashion, is produced in large quantities, and is priced affordably. Fast fashion has come under fire from a wide range of people due to the fact that no worker receives the minimum wage, yet products must be mass-produced. In addition to examining the legal and regulatory framework for protecting Bangladesh garment industry workers to fulfill their rights as laborers and how these rights are applied, this article looks at the shadowy side of fast fashion in Bangladesh. This paper elaborates on Bangladesh's experience in managing the situation of a garment industry building that collapsed in 2013, killing hundreds of people inside, using a normative analysis-oriented approach. This study demonstrates that Bangladesh's legal and regulatory framework for worker protection has yet to explicitly state what rights workers are entitled to. Another factor is that Bangladesh does not yet have a robust and consistent practice of human rights-based instruments considered in court and that law enforcement does not fully grasp how to execute these rights. At the same time, it is crucial to improve law enforcement interpretation for worker-focused solutions, giving their rights, and promoting human rights practices in Bangladesh.
Notas sobre o ecumenismo no magistério do Papa Francisco
Authors: Wolff Elias
Published: September 2024

This article aims to verify the contributions of Pope Francis' teaching to ecumenism. It analyzes elements of this pontificate that directly or indirectly promote dialogue between churches, and verifies an expansion of the meaning of ecumene through dialogue between religions and cultures, aiming at universal fraternity and care for the Common Home. It analyzes Francis' ecumenical spirit and the different notions of ecumenism that he expresses in his proposal for a culture of encounter and dialogue. The research method is the qualitative analysis of the bibliography that allows us to understand Francisco's ecumenical teaching, prioritizing documentary analysis. The results show that Francis' pontificate is fruitful for the cause of ecumenism, with insights that make it possible to advance along paths of dialogue only begun in Vatican II. These are elements that, if explored, enable real progress for ecumenism in our time.
Chiesa d’Oriente e Chiesa d’Occidente
Authors: Bianchi Luca
Published: September 2024

Christian unity has always been a desire and a challenge in the history of Christianity. The schism of 1054 is thus a symbolic moment of constant challenge. The present text seeks to make a journey along the path of ecumenical dialogue, especially between the Catholic Church and the Eastern Churches, trying to understand the reasons for separation and, at the same time, the effort to find a way of dialogue. The basis of the research are the documents developed by the Catholic Church, and those prepared in collaboration with other Churches. He also wishes to reflect on the traditions of the Christian East, with the aim of promoting the ecumenical journey of believers in Christ towards full communion and unity. It highlights the role of the Second Vatican Council and its consequences for ecumenical dialogue, highlighting the relationship with the Eastern Churches, especially after the collapse of communism in Eastern Europe. It also underlines the magisterial role of Popes Paul VI and John Paul II, who continued ecumenical dialogue in the commitment to make the Church breathe with both lungs. On this journey we have moved from the dialogue of charity to the dialogue of truth. The steps taken in recent years are described with the documents resulting from the dialogue: Monaco (1982), Bari (1987), Valamo (1988), Balamand (1993), Ravenna (2007), Chieti (2016) and Alessandria (2023).

Acutely toxic substances such as cyanide salts and mercury metal are commonly used in gold mining. Mercury amalgamation in artisanal gold mining is especially problematic and the largest source of mercury pollution on Earth. New strategies are needed that do not rely on cyanide and mercury for gold recovery. To address this problem, trichloroisocyanuric acid, activated by a halide catalyst, was used to oxidatively dissolve gold metal. A polysulfide polymer sorbent was then used to selectively bind the gold, even in complex mixtures. The gold can be recovered in high purity by pyrolyzing the sorbent. Alternatively, a recyclable polysulfide sorbent was made that can be depolymerized in its separation from gold. This material was synthesized using a novel photochemical ring-opening polymerization of a cyclic trisulfide. These integrated extraction and recovery methods were validated on ore, electronic waste, and other mixed-metal waste streams. Prospects for uptake are discussed.

Published: September 2024

As the demand for high-energy batteries to power electric vehicles continues to grow, Ni-rich cathode materials have emerged as promising candidates due to their high capacity. However, these materials are prone to rapid degradation under increased voltages, posing significant challenges for their long-term stability and safety. In this study, we investigate the effects of tantalum (Ta) doping on the performance and stability of LiNi0.80Mn0.1Co0.1O2 (NMC811) cathode materials. Using a combined theoretical and experimental approach, we employ Density Functional Theory (DFT) and Cluster Expansion models to analyze the electronic structure and oxygen vacancy formation enthalpy in Ta-doped NMC811. Experimental validation is conducted using cycling and gas measurements via On-line Electrochemical Mass Spectrometry (OEMS) on in-house synthesized cathode active materials.

The article considers the international legal consolidation of one of the areas of cooperation of states in the fight against human trafficking — protection of victims of these crimes. The authors disclose the characteristics of the provisions of several interna-tional documents, participant of which is Russia. Particular attention is paid to the features of the content and the possibility of applying the established protection measures in practice. Therefore, the UN guidance documents are marked, designed specifi-cally for the protection mechanism. Regional international legal regulation within the CIS of protection of victims of trafficking in human beings is analyzed. The authors refract all the analyzed documents to the Russian legislation. The presented final conclu-sion indicates the insufficient level of participation of our country in the creation of a national mechanism for the protection of victims and the implementation of the measures considered as international obligations of the state.

Published: September 2024

aim: This research examines the characteristics and survival outcomes of patients receiving a lung cancer diagnosis after attending the emergency department (ED) of Waikato hospitals in New Zealand. methods: This retrospective study was based on a comprehensive database of Waikato patients recorded on the Midland Lung Cancer Register from 2011 to 2021. We compared the characteristics of patients with and without emergency presentations within 14 days before their lung cancer diagnosis. The survival of patients with and without ED attendance was compared between Māori and non-Māori. This study also analysed the odds ratios (OR) of presenting via ED before diagnosis and surviving 12 months based on logistic regressions. results: In total, 2,397 patients were included, with 39.6% attending the ED prior to diagnosis. Māori were 1.27 times more likely than non-Māori to be diagnosed after attending the ED. Other characteristics of patients included being male, being diagnosed with small cell lung cancer and having more advanced-stage disease. Patients attending the ED were less likely to survive 12 months than those without ED visits (OR 0.42), and those with two or more ED visits were even less likely to survive 12 months (OR 0.33). conclusion: Patients presenting through the ED have more advanced-stage disease, while those presenting through their general practitioners (GPs) have evidence of being diagnosed earlier and having better survival. Barriers to early diagnoses through attendance with a GP, particularly for Māori and for men, need to be explored.

Respiratory arrest secondary to megaoesophagus is a rare complication of achalasia. We treated an 85-year-old female with a history of achalasia who presented with sudden respiratory arrest and cardiopulmonary resuscitation in the community. In the emergency department, she was intubated for respiratory distress secondary to upper airway obstruction and reduced consciousness. Flexible nasal endoscopy revealed a retropharyngeal bulge, and computed tomography (CT) demonstrated megaoesophagus with distal tapering. She was managed with gastric decompression and percutaneous endoscopic gastrostomy (PEG) feeding with an uncomplicated hospital course. This case provides a rare differential for a patient with acute upper airway obstruction and cardiopulmonary arrest and is the first such case described in the literature in Aotearoa New Zealand.
Avian community composition and its variation across kauri forests in the Waitākere Ranges infected with Phytophthora agathidicida
Authors:   , Turner-Steele Joseph
Published: September 2024

Kauri (Agathis australis) is an environmentally and culturally important tree species that is threatened by the disease known as kauri dieback, caused by the pathogen Phytophthora agathidicida (PA). Given the known effect kauri has on controlling the forest species around it, there is still little known on the effect that kauri dieback is having on the larger ecosystem, and whether bird communities are responding to the disease presence. Acoustic recordings were used to assess the prevalence of bird species over four seasons in six plots across the Waitākere Ranges. Each plot was given an infection score from a combination of PA presence and the canopy health of 10 sample kauri trees. Tree community composition was established from stem counts and total basal area from all the tree species in each plot. Multidimensional scaling analyses were done to assess the similarities between plots based on the tree community composition and separately for the bird community composition. The axes from the basal area MDS as well as the infection score were used as predictors in a linear mixed effect model testing the response of each bird species. While controlling for seasonal differences as a random effect. Twenty bird species were recorded across the six plots, with only 10 appearing above at least once per day when averaged. The composition of species changed significantly at each plot across the seasons, with all species being more abundant in summer and spring. When bird prevalence was plotted in summer/spring seasons against infection levels, Pīwakawaka (fantail), Miromiro (tomtit) , and Tūī showed a suggestive trend towards higher prevalence at lower infection plots, with Tauhou responding in the opposite direction. However, when run through the linear mixed effect model, only three species had any significant response, and this was in response to the first axis of the multidimensional scaling plot assessing tree community composition that appeared to correlate with kauri dominance. Blackbird responded positively, while Pīwakawaka and Ruru responded negatively. There was no statistical response to infection presence in any species. A mantel test between the bird community and tree community dissimilarity index also found no statistical correlation between the two (rM = -0.175, p-value 0.73). These findings suggest that while bird communities do differ between plots, it is unclear what is the cause of the difference.

Published: September 2024

Purpose: The purpose of this study presented bibliometric analysis of earnings management (EM) research and provides information on main results and new developments in this field of study. Deliberate manipulation of financial reports, known as earnings management (EM), has received widespread attention from the academic community in recent decades. 
Methodology/ Design/ Approach: This study utilizes VOS viewer software for bibliometric analysis of 1975 articles archived in the Scopus database between 2001and 2023.
Findings: The results show significant relationships between EM with corporate governance, performance metrics, and information quality. The study serves to trace publications and categories as a kind of context for understanding development and EM research emphasis. It also indicates the most productive authors, countries, Institutions and journals on the topic.  An analysis of clusters using keywords highlighted new trends in EM research. Notably, this study identified a possible class of real activities that had never been studied in EM before, warranting future work. 
Research Limitations/Implications: The major limitations of this research are that it uses a single database Scopus and only one search term (“earnings management”), and the selection of journal articles, excluding other publication types, is another limitation. 
Originality/ value: This study identified a global perspective that is unique in the existing EM literature, and other similar bibliometric studies were limited in their focus on specific subtopics of EM. It discusses the demand for arranging this unorganized domain of study. Additionally, it is an important contribution to the scientific literature on EM research and an excellent source for studies based on the current state of knowledge.
EU Association Agreement with Ukraine and Unrecognized Territories
Authors: Mushak Natalia , Muraviov Victor
Published: September 2024

The focus of this article is a legal analysis of the status of Crimea and the so-called Donetsk People’s Republic (DPR) and Luhansk People’s Republic (LPR) that are parts of the Ukrainian territory that was annexed and separated as a result of the Russian invasion. The authors state that Russia brutally violated the principles and norms of international law and that Russia’s military invasion has been condemned strongly by the international community. Moreover, international sanctions have been introduced against Russia and these territories. Russia’s annexation of Crimea and the unrecognized status of the so-called DPR and LPR largely determines the effects of the Association Agreement (AA) between the EU and Ukraine regarding these territories. The formation of a free trade area stipulated in the AA cannot cover Crimea or the so-called DPR and LPR. These territories and their populations cannot enjoy to the full extent the preferences obtained by Ukraine after the AA came into force. Ukrainian legislation concerning the legal status of Crimea and the so-called DPR and LPR is also analyzed in detail.
