Published: June 2022

Water management for natural channels is a frequent challenge due to the inefficient usage of water resources. The 2030 Agenda of the United Nations (SDG 6 of sustainable development) focuses its attention on water and sanitation. The Sara Guerrero site, located in the Mocache municipality in Los Ríos province (Ecuador), has issues related to access to drinking water, flood control, and crop irrigation that affect 4300 people and 24,000 hectares. The river overflows throughout the rainy season (late December to early May), whereas there is a noticeable water shortage during the dry season. This project aims to design a multiple-use earth dam on the Vinces River, simulating the resulting flow in extreme cases due to its possible failure. Such a study implies the development of a contingency plan for the preservation of life. It considers (i) dam breach analysis and design, and (ii) hydraulic model development using the ArcMap and HEC-RAS software packages. The design includes a waterproofing system that controls possible leaks and a cymbal spillway, mainly for raw water collection. The generated model showed that the shorter the failure time, the higher the maximum output flow. Modelling revealed that four towns would be affected for a maximum of 31 h in extreme cases. This approach offers comprehensive management for this community with regards to the earth dam and flood control.
Scour at a Submerged Square Pile in Various Flow Depths under Steady Flow
Authors: Du Shengtao , Wu Guoxiang , Liang Bingchen , Zhu David Z. , Wang Risheng
Published: June 2022

Local scour around submerged piles in currents are common in coastal and offshore engineering. This paper studies the influences of the submergence ratio (flow depth to pile height) on local scour around a square pile in steady flow. Submergence ratio ranging from 1–4, as well as two unsubmerged tests, were tested with a 10 × 10 square pile of 20 cm height. The three-dimensional profiles were measured to study the scour and deposition characteristics. Results show that the maximum scour depth was always at the upstream corner points rather than at the symmetry center point of the pile. The temporal maximum scour depth achieved its equilibrium sate in less than 4 h for each test. The equilibrium scour depths at the upstream corner points were independent of the submergence ratio when the latter was larger than 1.5. These findings give meaningful reference to the numerical simulations and local scour depth protections in the submerged pile cases deeper than which the flow depth does not affect the equilibrium scour depth.

Published: June 2022

Tanneries produce large amounts of wastewater with high concentrations of suspended solids, organic matter, and salts. Treatment and reuse of these effluents are of great importance to preserve water resources and save costs. Although suspended solids and high percentages of organic matter can be eliminated by physico-chemical and biological processes, refractory chemical oxygen demand (COD) and salts will remain in the wastewater after these processes. In particular, chloride and sulphate ion concentrations may hinder the treated wastewater from being reused or even discharged according to legal standards. In this work, two nanofiltration membranes and two reverse osmosis membranes are tested to assess these technologies as regeneration processes for biologically treated tannery wastewater. Permeate flux and rejection of organic matter and ions were measured at different operating conditions (transmembrane pressure and cross-flow velocities) at both total recycle and concentration modes. Results showed that the difference between permeate fluxes of nanofiltration (NF) membranes and reverse osmosis (RO) membranes was very high. Thus, at 20 bar and 1.77 m·s−1, the permeate flux of the two tested NF membranes in the total recycle mode experiments were 106 and 67 L·m−2·h−1, while the obtained permeate fluxes for the RO membranes were 25 and 18 L·m−2·h−1. Concerning rejections, RO membranes rejected almost 100% of the salts, whereas NF membranes reduced their rejection when faced with increasing concentration factors (salt rejection between 50–60% at the highest concentration factor). In addition, the fouling of RO membranes was lower than that of NF membranes, recovering more than 90% of initial permeability by only water rinsing. In contrast, chemical cleaning was necessary to increase the permeability recovery of the NF membranes above 90%. The considerably lower rejections and the higher membrane fouling of the NF membranes lead us to conclude that reverse osmosis could be the most feasible technique for water reuse in the tannery industry, though the permeate fluxes are lower than those achieved with NF membranes.

Carbamazepine Removal by Clay-Based Materials Using Adsorption and Photodegradation
Authors: Levakov Ilil , Shahar Yuval , Rytwo Giora
Published: June 2022

Carbamazepine (CBZ) is one of the most common emerging contaminants released to the aquatic environment through domestic and pharmaceutical wastewater. Due to its high persistence through conventional degradation treatments, CBZ is considered a typical indicator for anthropogenic activities. This study tested the removal of CBZ through two different clay-based purification techniques: adsorption of relatively large concentrations (20–500 μmol L−1) and photocatalysis of lower concentrations (<20 μmol L−1). The sorption mechanism was examined by FTIR measurements, exchangeable cations released, and colloidal charge of the adsorbing clay materials. Photocatalysis was performed in batch experiments under various conditions. Despite the neutral charge of carbamazepine, the highest adsorption was observed on negatively charged montmorillonite-based clays. Desorption tests indicate that adsorbed CBZ is not released by washing. The adsorption/desorption processes were confirmed by ATR-FTIR analysis of the clay-CBZ particles. A combination of synthetic montmorillonite or hectorite with low H2O2 concentrations under UVC irradiation exhibits efficient homo-heterogeneous photodegradation at μM CBZ levels. The two techniques presented in this study suggest solutions for both industrial and municipal wastewater, possibly enabling water reuse.

Published: June 2022

Distribution and carbon biomass of planktonic foraminifera were investigated from the euphotic zone of the Eastern Indian Ocean during a two-month cruise, ‘Shiyan I’ (10 April–13 May 2014). Foraminifera species were collected through plankton net sampling at 44 locations (80.00°–96.10° E, 10.08° N–6.00° S). The temperature (°C) ranged between 12.82 and 31.8 °C, the salinity ranged between 32.5 and 35.5, and chlorophyll-a concentrations ranged between 0.005 µg/L and 0.89 µg/L. A total of 20 taxa were identified based on the spherical chamber shell, spines, and a final whorl which were examined under light microscopy and scanning electron microscopy. Dominant species that were characterized by the high dominant index Y > 0.14–0.46 were Globigerina bulloides, Globigerinoides ruber white, Globigerinella siphonifera, Turborotalita quinqueloba, and Globigerinella calida, contributing to the community up to 86%. The shell size of collected taxa was from 51 to 508 μm and the total carbon biomass was estimated to be between 0.062 µg C m–3 and 26.52 µg C m–3. The high carbon biomass was recorded at two stations in the equator zone. Due to its large size, Globorotalia menardii had total carbon biomass of 3.9 µg C m–3, followed by G. calida 0.68 µg C m−3, Trilobatus sacculifer 0.38 µg C m–3, Orbulina universa 0.56 µg C m–3, and G. ruber white 0.22 µg C m–3, respectively. The Pearson correlation analysis showed that the temperature and chlorophyll-a were two explanatory environmental variables that were found to be highly significant (p < 0.05) and that triggered the distribution and abundance of dominant foraminifera species in the study region. Overall, high abundances and carbon biomass were derived from the euphotic zone and equatorial region of the Eastern Indian Ocean.
Fuzzy Yaw Rate and Sideslip Angle Direct Yaw Moment Control for Student Electric Racing Vehicle with Independent Motors
Authors: Sawaqed Laith Sami , Rabbaa Israa Hasan
Published: June 2022

In this paper, a new concurrent yaw rate, sideslip angle, and longitudinal-velocity direct yaw moment control (DYC) strategy is proposed to improve the handling and stability of a rear-wheel drive student electric racing vehicle (EV) equipped with two independent motors. In order to control these three parameters concurrently, three control schemes are developed: three fuzzy controllers, three optimized PID controllers, and two fuzzy controllers for the yaw rate and sideslip angle with a PID for longitudinal velocity. The EV dynamic behavior for the different control schemes is compared by using a nonlinear model of the EV. This model consists of three main parts: vehicle dynamics, wheel dynamics, and tire dynamics. Simulations under a circular-path driving scenario show that the proposed fuzzy controllers can effectively reduce the consumed energy by 10%, track the desired speed and path, and enhance the vehicle’s behavior and stability while maneuvering by decreasing both the yaw rate and sideslip angle deviation.
Improved Model Predictive Current Control of NPC Three-Level Converter Fed PMSM System for Neutral Point Potential Imbalance Suppression
Authors: Zhang Guozheng , Liu Qiyuan , Wang Jian , Li Chen , Gu Xin
Published: June 2022

For the neutral point clamped (NPC) three-level converter fed permanent magnet synchronous motor (PMSM) system, the performance of the conventional model predictive current control (MPCC) algorithm will be deteriorated if the amplitude of the neutral point potential (NPP) is large. Additionally, the adjustment process of the weighted coefficients of the conventional MPCC algorithm is complex because of numerous control terms in the cost function. To solve the above issues, an improved MPCC algorithm is proposed in this paper. Firstly, Newtonian iteration is used to transfer the stator current into stator voltage in the cost function. Then, the NPP term in the conventional cost function can be eliminated by introducing the partition control of the NP potential, which also eliminates the whole adjustment process of weighting coefficients. Finally, based on the amplitude of the NPP, the amplitude and phase angle of medium and small vectors are modified to improve the control performance of the torque and flux. Experimental results show that the fluctuation of the neutral point potential can be suppressed rapidly. Meanwhile, the performance of the torque, flux and current are also improved compared with the conventional MPCC.
Wind Farm Deployment in Uninhabited Islets: A Case Study the Region of the South Aegean (Greece)
Authors: Vagiona Dimitra G. , Alexiou Vasiliki
Published: June 2022

The transition of nations to renewable energy sources is a fact, and the deployment of renewable energy (RE) projects has increased in the last decades. The deployment of energy projects in uninhabited islets (islands) provides a promising opportunity for low-carbon energy transition. Considering the importance of the spatial dimension of RE projects, in this research, we identified and ranked uninhabited islets (UIs) for wind farm deployment in the South Aegean Sea, Greece. The proposed methodology combines geographic information systems (GIS) and two multicriteria analysis methods (AHP and TOPSIS) using some restrictions found in Greek law as well as assessment criteria considering environmental, economic, and technical aspects. The appropriate UIs were then ranked under four different policy scenarios (baseline, equal criteria weights, a policy scenario oriented to technical/economic criteria, and a policy scenario focusing on environmental criteria). The results indicated the existence of three UIs for siting wind farms in the region of the South Aegean, with the same ranking of these UIs under different scenarios. The proposed methodology provides useful guidelines for selecting UIs as wind farm sites in Greece and could be applied in other countries worldwide.

Published: June 2022

Relevance. We have developed and patented a mobile application for monitoring and normalizing the mastication muscle functional state to solve the problems of detecting people with suspected dysfunction of the jaw muscles and increase the efficiency of muscle exercises.

Purpose. To evaluate the positive effect of the mobile application to control and normalize the mastication muscle functional state in the clinical orthodontic practice.

Material and methods. The study included 74 patients of Children Clinical Dental Clinic No. 2 of Voronezh, aged 6 to 12 years, who presented for a dental check-up. The masseter muscle tone was determined using the Mioton-3S device.

Results. The authors’ method of self-examination does not give a systematic overestimation or underestimation of parameters (p = 0.083) compared to the standard myotonometry, which evidences its reliability and the possibility to use for preliminary examination and detection of people with suspected abnormal muscle tone. The analysis of the masseter muscles’ tone one month later revealed a statistically signifcant (p = 0.034) decrease in the number of patients with tone disorder among the mobile application users compared to the patients who did not use the application.

Conclusion. The developed mobile application is efficient for preliminary assessment and detection of people with suspected abnormal muscle tone. Mobile application helps increase efficiency and awareness of muscle exercises.

Published: June 2022

This study identified Phalacronotus to species level and examined its morphometric variation among three collection localities, and between sexes, in the Mekong Delta, Vietnam. Specimens were collected from local markets and fishers, including An Giang (n = 36) and Can Tho (n = 36) in the Hau River and Tien Giang (n = 30) in the Tien River for morphological measurements and DNA barcoding analysis. Eight mitochondrial cytochrome oxidase subunit I (COI) sequences of Phalacronotus sp. shared 99.6 ± 0.23 % similarity with five GenBank (GB) P. bleekeri sequences and differed by 7.6 % to 13.3 % from seven GB P. apogon sequences. The Vietnamese specimens of Phalacronotus were similar to P. bleekeri in number of anal fin rays (75–80) and the shape of the upper jaw teeth. Thus, the COI sequences and these morphological characteristics indicate that Phalacronotus sp. samples collected in the Mekong Delta are Phalacronotus bleekeri (Günther, 1864). Morphometric characteristics differed between populations in 15 of 19 indices (P < 0.05) and between females and males in three characteristics relating to the belly. Head characteristics, body depth, and caudal peduncle depth were the main parameters contributing to the inter-population variation. Based on size-adjusted data, 96.7 % of specimens were correctly classified from the Tien Giang population, while 27.8 % and 33.3 % were misclassified between the Can Tho and An Giang populations, respectively. These results indicate that morphometric parameters of P. bleekeri varied mainly between populations in the two Mekong River tributaries.

The Baikal Teal, Russia's nesting endemic, is listed in the Red Book of the Russian Federation as a declining species.The Baikal Teal has always been rare in Chukotka Autonomous Okrug; therefore, its abundance fluctuations in this area have never been documented, and, historically, its nesting has been recorded there just once. According to aerial surveys, the Baikal Teal average density in Western Chukotka's tundras was 0.08 individuals / km2 in 2021. Birds of this species were recorded everywhere: on the Kyttyk Peninsula and Aion Island, in the Chaun-Pucheveem delta, in the Pegtymel River delta, and in the Apapelgino settlement precincts. Nesting of this species in the Chaun - Pucheveem River delta has been proved.

Background: Low back pain, especially non-specific low back pain (NSLBP) is a big challenge to healthcare professionals including physical therapists. Physical Therapists employ varying modalities including spinal manipulation when treating NSLBP. Recently, there is a huge interest and use of drying needling/acupuncture in the management of NSLBP. However, there are limited studies in the literature that examined and compared the efficacy of spinal manipulation and or dry needling/acupuncture in the management of low back pain (LBP). Objective: The purpose of this systematic review is to examine and compare the efficacy of spinal manipulation and/or dry-needling/acupuncture for the treatment of NSLBP. Methods: An electronic search of Embase and Pubmed were performed to collect randomized control trials. Studies were included with the following criteria: 1) human trials, 2) published in English, 3) participants were adults eighteen years and older with NSLBP, and 4) comparisons of spinal manipulation and/or dry-needling/acupuncture. The PEDro scale was used to assess the risk of bias of each study included in this systematic review. Results: The electronic search resulted in 381 potential articles, five meeting the criteria. Three out of the five studies show spinal manipulation provides superior outcomes with having significant P-values for Oswestry Disability Index (p-values between 0.0004 - 0.01), Visual Analog Scale (p-values between 0.0001- 0.005), and Short Form-36 (P-values between <0.001 - 0.006). Risk of bias was assessed using the PEDro scale which determined two articles to be high-quality (≥7/10), two moderate quality (5-6/10), and one poor quality (≤4/10). Conclusion: Three out of the five studies showed spinal manipulation provides superior outcomes with having significant p-values when compared to DN/acupuncture. In one of the studies, both manipulation and acupuncture were equally effective in the management of LBP with no superiority of either of the interventions. It is suggested that in the management of NSLPB, spinal manipulation should be considered as first option or be considered in the arrays of other therapeutic interventions. The authors suggest that clinical trials at a larger scale to be conducted to validate a better efficacy of spinal manipulation compared to dry needling/acupuncture and whether there is any synergy between them when treating NSLBP.

Background: As women age, hormone levels change and put them at increased risk for osteoporosis. Tai Chi is a weight bearing exercise intervention that incorporates balance. Balance training and weight bearing exercises have both been shown to be beneficial to those with or at risk of osteoporosis by benefiting bone mineral density and decreasing fall risk. Objective: The purpose of this systematic review is to determine whether Tai Chi is an effective intervention for improving balance in women with or at risk for osteoporosis. Methods: A search of PubMED and EMBASE databases was completed using search terms related to osteoporosis, Tai Chi, and balance, and was limited to randomized control trials, clinical trials, and research articles. The authors screened the resultant studies by title, abstract, and full text. In order to qualify for inclusion in this study, articles must have had a measure for balance before and after intervention, Tai Chi as an intervention, and women 45 or older as study subjects. Five studies were assessed for quality using the PEDro Scale and one study was assessed using the Quality Assessment Tool for Before-After (Pre-Post) Studies With No Control Group. Results: Six articles remained for inclusion in the review after screenings. Four out of six studies reported significant differences in at least one balance outcome measure post-intervention. Studies that had longer intervention periods resulted in more significant findings in the outcome measures of interest. Conclusion: Results from this systematic review suggest that Tai Chi may have positive effects on balance in women with or at risk of osteoporosis. Further research is recommended due to the heterogeneity of balance outcome measures, as well as length of intervention, with some studies indicating that longer intervention periods may increase benefits of Tai Chi.

Competences of academic tutors – research among participants of the project “Masters of Didactics”
Authors: Duda Ewa
Published: June 2022

The research aimed to identify and then to characterise the self-assessment of the level of tutor competences of academic teachers participating in the project "Masters of Didactics" - implementation of the tutoring model. The basis for a description of tutor competences was the "European competence matrix for tutors" developed within the Certification for Mentors and Tutors (Certi.MenTu) project aimed at the certification of competences of mentors and tutors according to the European Standard EN ISO 17024. The selected tutoring competences described in this project were applied to the academic environment. Seven areas of these competences were created. These included: Communication and relationships; Working with and supporting tutees; Effective learning; Monitoring tutees' progress; Evaluation of tutoring. The research questions concerned the overall picture of tutoring competences, the developmental nature of these areas. We were also interested in socio-demographic factors that may differentiate the level of competence of tutors. The method used was a diagnostic survey, and the technique was an online survey with open and closed questions. The research was conducted among 78 lecturers from the Polish academic environment. The results indicate that academic tutors perceive themselves as adequately prepared to carry out the tutoring process, while at the same time being aware of the need for improvement, especially competences in the area of knowledge, organization, and evaluation of the tutoring programme at the university. Tutoring competences are independent of gender and academic degree of academic teachers but differentiated by academic discipline.

Published: June 2022

Purpose. To assess the disorders of the cardiac conduction system (CCS) that occurred in the early postoperative period after aortic valve (AV) replacement by the Ozaki method.

Methods. The study included 256 patients after a successfully performed Ozaki procedure. Patients with a history of open cardiac surgery, with an implanted pacemaker, with permanent atrial fibrillation, with simultaneous Ozaki surgery with correction of another pathology, in case of repeated surgery on AV in the next six months, with lethal outcome, under the age of 18 years, when it is impossible to analyze the CCS dynamics were excluded. The mean age was 57.9±11.1 years, the male sex was 119 people (46.5%), the body mass index was 29.7±5.5 kg/m2 , diabetes was observed in 40 patients (15.6%), anamnesis of CCS disorders in 10 (3.9%), CCS disorders on the baseline electrocardiogram (ECG) in 32 (12.5%). Conduction abnormalities were assessed according to the anamnesis and the results of daily ECG recording.

Results. In the early postoperative period, CCS disorders were registered in 35 patients (13.7%), of whom 27 (10.6%) had their first occurrence, and 8 (3.1%) had previously existed. By the time of discharge, persistent CCS disorders (which occurred for the first time and in the case of progression of pre-existing blocks) remained in 11 (4.3%): 8 (3.1%) had bundle branch blocks, 3 (1.2%) had atrioventricular blocks that required implantation of a permanent pacemaker. Patients with pacemaker had initial conduction abnormalities. The most frequent dysfunction of the CСS was the left bundle branch block (LBBB) (45.5%). We analyzed 14 variables as predictors of the onset or progression of persistent CCS disorders. Two independent predictors were identified - the presence of conduction abnormalities on the baseline ECG and the time of cardiopulmonary bypass. In patients with persistent conduction disturbances in the postoperative period, CCS disorders on the baseline ECG were more common - 36.4% compared with patients without CCS disorders after surgery - 11.4% (p=0.035) and there was a longer duration of cardiopulmonary bypass 140.6±41.1 min. and 122.4±26.1 min. respectively (p=0.03).

Conclusion. The most frequent disorder of the conduction was the LBBB. None of the first dysfunctions of CCS led to the implantation of the pacemaker. The presence of initial ECG conduction disturbances and the time of cardiopulmonary

Background: The frequency of occurrence of infectious complications after hip arthroplasty in HIV-infected patients is extremely high. Revision arthroplasty for periprosthetic infection is the leader (64%) among the causes of early revision interventions. The search for ways to increase the efficiency of the sanitizing stage of treatment due to antibacterial coatings of the endoprosthesis components continues.

Objective: Demonstration of a clinical case of treatment of periprosthetic infection in an HIV-positive patient using a spacer and a femoral component of a hip joint endoprosthesis coated with linear Sp1 carbon chains and silver. 123 months after hip arthroplasty for stage 3 dysplastic coxarthrosis in HIV-positive patient of 42 years old developed an instability of the acetabular component with the growth of Staphylococcus aureus in punctates. A revision was performed with the removal of the endoprosthesis and the installation of an articulating spacer with the addition of antibiotics. 12 weeks later, a recurrence of periprosthetic infection occurred, and Enterococcus faecalis was detected in punctates. During re-endoprosthetics, there was an installation of an articulating spacer covered with a two-dimensionally ordered linear-chain carbon doped with silver, based on the Zimmer CPT femoral component and bone cement with antibiotics addition. After 3 months, the second stage of revision arthroplasty was performed with implantation of an individual acetabular component and a femoral component coated with two-dimensionally ordered linear-chain carbon doped with silver.

Conclusion: 4 months after the operation the patient returned to work, 12 months later the functional results were satisfactory. The use of components coated with two-dimensionally ordered linear-chain carbon doped with silver in an HIV-positive patient with recurrent periprosthetic infection made it possible to stop the infectious process, improve limb function and the quality of life.
Convergence of Islam and Democracy
Authors: Fajar Fajar
Published: June 2022

This studyattempts to analysethe relationship between Islam and democracy objectively with logical rational arguments. It aims to clarify the differences between Islam and democracy in terms of values and concepts, in addition to explaining the reasons for the rejection of some Muslims against democracy and the arguments underlying their rejection. Then, itattempts to draw a theoretical relationship between Islam and democracy by asking critical questions, logical assumptions, and arguments that rely on the empirical practice of implementing democracy in Indonesia. Islam and democracy were born from two different ontological areas. Islam as a religion is believed to be sacred and absolute truth because ontologically its teachings come from God. While the democratic political system was born from the historical trajectory of human cultural development, it means that democracy is profane secular, and the truth is contextual perspective of the status quo of Muslim elite power politics. The concept of democracy in terms of genealogy, values, and orientation is not entirely the same as Islamic teachings, but it is not denied that Islamic teachings are in many respects substantially in line with the concept of democracy. Thus, Indonesia is a country with the largest Muslim population in the world, so it is fitting for Indonesian Muslims to become enforcers of democracy based on human religious values. That is a model of democracy that not only provides a place for the growth of people's beliefs or religiosity, but also provides space for the realization of human rights. Therefore, democracy as a concept, in its implementation, of course, must be adapted to the context and culture of the local community, especially Islamic communities such as in Indonesia and in the Middle East.
The Concept of Ta’abbudi and Ta’aqquli in Islamic Law
Authors: Keri Ismail
Published: June 2022

The discourse on the concepts of ta'abbudi and ta'aqquli in Islamic law is a discourse that always lives and develops in tandem with the development of science. Understanding the concept of ta'abbudi and ta'aqquli should continue to use the rules, norms and arguments that serve as guidelines. The concept of ta'abbudi and ta'aqquli, it is urgent to get a basic conception, as a reference in formulating the relevant concept of Islamic law. This study is a conceptual study of literature with a normative theological approach. The findings in this study are that ta'abbudi is a textual provision (The Qur’an and hadith) in the field of worship that must be obeyed even though they do not know the rational reasons, while ta'aqquli allows there to be benefits according to rational reasons, so that reason is given space. The object is also different, ta'abbudi is focused on mahdah worship, while ta'aqquli is in the matter of muamalah. In addition, ta'abbbudi is static, does not provide opportunities for ijtihad, while ta'aqquli provides opportunities for ijtihad. In the construction of Islamic law in the application of the concepts of ta'abbudi and ta'aqquli it turns out to have two legal dimensions. This means that there are certain problems that require ta'abbudi and also conditions that require ta'aqquli. It is not focused on the meaning of lafadz, but rather on the implementation of the law. Because the form of benefit lies in the philosophical meaning of Allah's decree which will have implications for human actions.

Authors: Nawawi Jumriani
Published: June 2022

This research is focused on how positive law enforcement is in providing protection to children from the criminal act of neglection. This study aims to determine the phenomenon related to conflict that often occurs in society in the form of neglect of parents to their children. Protection of children from violent criminal acts in the form of neglection from parents has been strictly regulated in regulations. This type of research is normative juridical research. The research was conducted qualitatively by relying on library research. The results showed that the forms of child neglect were physical neglect, educational neglect, emotional neglect, and medical neglect. Regarding the neglect of children by their parents, they should be legally accountable. The criminal act of neglecting children by their parents is very clearly regulated in the Child Protection Law Number 35 of 2014 concerning Child Protection and the Criminal Procedure Code.
Reactualization of Criteria of Wealth in Islam as a Condition for Paying Zakat Maal
Authors: MH. Mustafa
Published: June 2022

This article examines the criteria of wealth in Islam as a mandatory requirement in paying zakat maal. The goal is that Muslims avoid being misled in carrying out material religious obligations, such as zakat, infaq, and alms. This research is normative by using a qualitative approach, in describing the results of the study. The results show that the criteria of wealth are defined as the benchmarks used by syara’ in determining a Muslim is called wealthy (Muzakki), namely: First, if you have assets that exceed your basic needs and are free from debt; Second, a Muslim is considered rich, if he has more productive assets than consumptive assets; Finally, possession of property that reaches the niṣab, any type of property is equivalent to the gold niṣab of 20 miṡqāl.

Noncooperative Equilibrium Seeking in Distributed Energy Systems Under AC Power Flow Nonlinear Constraints
Authors: Scarabaggio Paolo , Carli Raffaele , Dotoli Mariagrazia
Published: June 2022

Power distribution grids are commonly controlled through centralized approaches, such as the optimal power flow.

However, the current pervasive deployment of distributed renewable energy sources and the increasing growth of active players, providing ancillary services to the grid, have made these centralized frameworks no longer appropriate.

In this context, we propose a novel noncooperative control mechanism for optimally regulating the operation of power distribution networks equipped with traditional loads, distributed generation, and active users. The latter, also known as prosumers, contribute to the grid optimization process by leveraging their flexible demand, dispatchable generation capability, and/or energy storage potential.

Active users participate in a noncooperative liberalized market designed to increase the penetration of renewable generation and improve the predictability of power injection from the high voltage grid. The novelty of our game-theoretical approach consists in incorporating economic factors as well as physical constraints and grid stability aspects. Lastly, by integrating the proposed framework into a rolling-horizon approach, we show its effectiveness and resiliency through numerical experiments.

Authors: Karova Emilia , Adem Sherihan Zongova-
Published: June 2022

The aim of the study was to quantify the amount of apically extruded debris during root canal filling removal with D-Race and Mtwo retreatment systems. Twenty-four extracted single-rooted mandibular incisors with straight oval-shaped root canals were instrumented with XP-Endo Shaper files and filled with gutta-percha and AH Plus sealer using vertical compaction technique. All filled samples were temporarily sealed with Citodur Hard and stored in distilled water for 30 days. The specimens were randomly divided into two groups, according to the nickel-titanium system used for root canal filling removal (n=12). The retreatment procedure was performed with Mtwo Retreatment and D-Race Retreatment. The extruded debris during retreatment procedures, was collected in preweighted Eppendorf tubes. The actual weight of extruded debris was calculated by subtracting the initial weight from the final weight of the Eppendorf tubes. Statistical analysis was performed using IBM SPSS Statistics 23.0 software. The level of significance was set at P<0.05. The investigation results did not find statistically significant differences between the experimental groups. It could be concluded that retreatment with both Mtwo and D-Race cause apical extrusion of debris material with no statistically significant difference between the amounts produced by the two tested systems.
