This work presents the results of studies of the electrode potential of α, β and α+β brasses, determined corrosion currents in chlorine-containing environments, and conducted tests on their dezincification in a copper chloride solution. In order to more deeply study the properties of brass, corrosion currents and electrode potential in chlorine-containing environments were determined for pure metals: copper and zinc. In the course of the work, graphs were constructed of the potential of copper, zinc, α, β and α+β brasses versus the etching time in sodium chloride solutions and a sodium chloride solution with the addition of ammonium chloride. Corrosion currents were determined in a sodium chloride solution: for copper (38 μA), α brass (70 μA), α+β brass (113 μA), β brass (88 μA) and in a sodium chloride solution with the addition of ammonium chloride: for copper ( 14 μA), zinc (71 μA), α brass (37 μA), α+β brass (44 μA), β brass (42 μA). Based on the results of a study of the resistance of alloys to dezincification, the following data were obtained: dezincification depth of brass α – 450–500 μm, α+β – 950–1000 μm, β – 600–700 μm. The results of studies of corrosion currents in chlorine-containing environments correlate with the results of dezincification experiments. The studies carried out confirm the assumption that in double brasses the α and β phases form a corrosion element due to the difference in chemical composition, and, consequently, different electrode potentials, which leads to the loss of zinc to a slightly greater extent than in β brass.

The article presents studies of the stress-strain and temperature-velocity states of the AMg6 alloy during free-die forging. Numerical experiments on free-die forging of samples with a diameter of 15.0; 20.0; 25.0 and 30.0 mm were carried out in the QForm program. During the experimental studies, the free-die forging speed was 0.1, 0.5, 1 and 5 mm/s and the workpiece temperature was 20, 130, 260 and 390 °C. The research results showed that the side surface of the sample is a zone of maximum average stresses, and the periphery of the contact surface of the sample with the die is a zone of minimum average stresses during free-die forging. The maximum values of the shear stress intensity are located at the periphery of the contact surface of the sample with the die. The stress state indicator σ/T, which characterizes the minimum plasticity of the material being processed, during free-die forging takes on its maximum values on the side face of the sample and does not change its position with a change in heating temperature. An increase in the temperature of the sample during free-die forging leads to a decrease in the average stresses and the intensity of the tangential stresses, but the patterns of distribution of their maximum and minimum values remain unchanged when the temperature of the sample changes. Increasing the free-die forging speed from 0.1 to 5 mm/s leads to a slight increase in stress intensity by 15–20 MPa. Deformation heating significantly depends on the free-die forging speed and the initial temperature of the sample. The maximum deformation heating is localized in the central part of the sample. The deformation rate during free-die forging at a rate of 5 mm/s does not exceed 1.1 s–1. The distribution of strain rates over the cross section is uneven. During the free-die forging process, first the maximum stresses arise in the center of the workpiece, then they increase and spread along the forging cross. When the degree of deformation is more than 50 %, the maximum values move to the periphery of the contact of the sample with the dies and remain there until the deformation is completed. Free-die forging forces are largely determined by the size of the sample, its heating temperature, hardening during cold deformation and slightly depend on the forging speed.

The article is dedicated to the dissolution process of some rare-earth phosphates in carbonatealkaline media. The object of the study are model sediments of rare-earth phosphates. Different groups of the rare earth elements (REE) have been researched according to their masses: heavy-weight – holmium and ytterbium; medium-weight – samarium and gadolinium; light-weight – neodymium and yttrium though it does not belong to lanthanoids. REE-phosphates are impurity and taken place into technogenic waste phosphogypsum (PG). It is considered to be the PG has being be produced from 10 to 15 million tons per year. Because of the PG goes to disposal site, it causes ecological issues. For the rational use of natural raw materials, it is necessary to develop a solution that allows the phosphogypsum process into commercially valuable products. Concentrate of rare earth metals may be one of these. REE are widely used in various industries: defense, energy, electronics, metallurgy, catalysis and others. However, there are low-level production and incomplete production cycle in the several REE industry, this it is in need of import. Therefore, the study is aimed at achieving economic stability and technological sovereignty of the Russian Federation. The article demonstrates an illustration of the influence of temperature, concentration of carbonate solution, liquid to solid ratio and intensity of mixing on the REE-phosphates solubility. In the concentration range under consideration at a temperature of 90 °C, the maximum equilibrium degrees of extraction into solution were: E(Ho) = 75.6 %; E(Yb) = 85.5 %; E(Nd) = 62.5 %; E(Gd) = 71.6 %; E(Y) = 73.1 %; E(Sm) = 46.1 %. The results of this research are part of the thermodynamic analysis of the REEPO4 – K2CO3 system, which can subsequently be used to model the process of associated REE extraction from industrial waste (phosphogypsum, for example) by liquid carbonating conversion method.

Lead, tin and lead foil clad with tin are used in various branches of technology, medicine and the food industry. According to GOST 18394–2016, the thickness of the foil is in the range of 0.015–0.21 mm, and the width of the foil is 70–450 mm. The technology for manufacturing foil based on lead, tin and their alloys was developed quite a long time ago, in the 20s–30s of the last century. In the USSR and abroad in those years, due to the specific physical and mechanical properties of the rolled metals, cold rolling was used, implementing the roll and card rolling methods. The use of the roll or card rolling method at that time was determined, first of all, by the availability of appropriate equipment. Foil rolling was carried out on both reversible and non-reversible twin-roll rolling mills with work roll diameters of 230–700 mm. An analysis of the state of the technology and the equipment used for rolling foil made of lead, tin and lead foil clad with tin currently differs little from the technologies used in the USSR. In our opinion, this is explained by the small-tonnage orders, low yield (60–70 % of a strip billet 0.9 mm thick), low profitability and the disinterest of manufacturers in improving the technology. According to available information, the lead time for orders at some enterprises reaches up to 6 months. These shortcomings in meeting the demand for small-tonnage batches were noted in the Order of the Government of the Russian Federation No. 4260-R dated December 28, 2022. This paper presents the experience of manufacturing small-scale batches based on lead and tin in the conditions of RPA “R.O.S.Antiсor” LLC and SUSU. The research work carried out to develop the technology and test it for the conditions of the mentioned organizations made it possible to develop technological regulations for the production of foil and technical specifications for lead, tin and lead foil clad with tin.

Published: August 2024

Excess nitrogen fertilizer use leads to vegetables with high amounts of nitrate content. Consumption of vegetables with high amounts of nitrate is carcinogenic to human beings. In this study, fenugreek plants were grown under varying nitrogen fertilizer doses (0, 50, 100, 150, 200, 250, 300, 350 and 400 kg N/ha). A Vis-NIR hyperspectral imaging (HIS) camera captured images of fenugreek leaves within the 398–1,003 nm spectral range. The spectral data were pre-processed using different pre-processing techniques before the model development. Partial least-squares regression (PLSR) models were constructed with complete spectral data and selected wavelengths. The performance of the PLSR model decreased with pre-processed spectral data, and there was no significant difference compared to the model constructed with raw spectral data (R
2
CV = 0.915, SECV = 591.933, slope = 0.518 and RPDCV = 1.421). The wavelengths 411, 435, 466, 558, 669, and 720 nm were selected as feature wavelengths for representing nitrate content in fenugreek leaves. The performance of the PLSR model constructed with feature wavelengths (SECV = 648.672; RPDCV = 1.482; R
2
CV = 0.869) was non-significant compared with the model developed with raw complete spectral data (SECV = 591.933; R
2
CV = 0.915 and RPDCV = 1.421). Using the complete raw spectral data, the spatial distribution images of nitrate content in fenugreek leaves indicated that the nitrate content was concentrated near and along the midrib up to the apex. The overall results obtained in the present study suggest that VIS-NIR HSI, along with suitable chemometric techniques, can be used for rapid assessment of nitrate content in fenugreek leaves.

Published: August 2024

This study examines the effects of various M-shaped water wave shapes on coastal environments for the modified regularized long-wave equation (MRLWE). This work explores the complex dynamics of sediment transport, erosion, and coastal stability influenced by different wave structures using the Hirota bilinear transformation as a basic analytical tool. By providing insightful information about how these wave patterns impact coastal stability, it seeks to broaden our knowledge of dynamic coastlines. As we explore the intricate interactions between water waves and beaches, the knowledge gained from this research could help direct sustainable coastal management and preservation initiatives. For convenience, a range of M-shaped wave structures are depicted, demonstrating the adaptability of the Hirota bilinear transformation approach in recognizing novel wave patterns. Overall, this work contributes to a better understanding of the dynamics of the coastal environment, highlights the wide range of applications for mathematical models in science and engineering, and helps to develop more sensible and practical coastal management and conservation strategies for the protection of coastal areas against changing water wave patterns. Finally, as far as the authors could verify, this is the first work in the literature in which M-shaped soliton solutions are derived for the MRLWE using any method.

Phase inversion involves in a complex process due to numerous factors affecting the membrane formation. Among them, polymer chain entanglement from polymeric membrane materials plays a critical role in regulating membrane structure and is still worth further exploration. Herein, a series of methacrylate copolymers with different contents of poly(ethylene glycol) methacrylate (PEGMA) were designed and synthesized, and ultrafiltration membranes cast from these copolymers were systematically investigated regarding structural evolution and filtration performance. Surface zeta potential of membranes gradually transformed from positive to negative with the increasing PEGMA content due to nonsolvent-induced surface migration of element oxygen, and meanwhile the transformation from finger-like pore structure to sponge-like pore structure in the support layer was observed, which could be attributed to chain entanglement of the PEGMA-rich copolymer. Filtration experiments indicated that sponge-like membranes possessed better separation effect of Victoria blue B compared with finger-like membranes, and the optimized mPP40-15 % showed a retention rate of 99.55 % and permeance of 110.26 L m−2 h−1 bar−1 and displayed good selective separation of dye/salt mixture. Besides, sponge-like membranes also exhibited easy regeneration, anti-fouling property and filtration stability. This work will provide guidance for modulating membrane structure and offer an alternative material for membrane separation in handling dye wastewater.
In Search of an Electrified Future: The Affective Afterlife of the Extractive Industry in Mitrovica, Kosovo
Authors: Berisha Rozafa
Published: August 2024

This article analyses hopes around the promissory potential of mineral resources through the lens of affect. Building on ethnographic fieldwork conducted between 2018 and 2019 in South Mitrovica in Kosovo, it explores how citizens of a de-industrialised and politically unstable city envision the future around and beyond the extractive potential of the Trepça mine. It does so by examining two encounters with two different modes of electricity – a power cut and New Year lights – as instantiations of the mine’s affective force that evoke the historically specific promise of modernity shaped during Yugoslav socialism. Through the motif of electricity, the article demonstrates how this industrial past orients collective hopes towards an extractive future. Retrospectively shaped, these hopes remain intangible, however, and riddled with doubts, friction, and contestation. Divergent visions, then, attempt to ground a viable future amid the uncertainties triggered by postsocialism, the war and its aftermath, and de-industrialisation.

Published: August 2024

This study proposes an anthropological approach to understanding the organization of the3. majshipyard in the city of Rijeka, Croatia. The article examines the shipyard through the prism of development attempts and the failed implementation of an effective information system between the 1970s and 2010s. It focuses on analyzing the shipyard’s internal organizational dynamics specifically in relation to the introduction of new technology, as well as its interrelations with external sociopolitical developments and developments in the shipbuilding industry. In order to achieve this, the author presents two kinds of relationships: one serving as an example of the shipyard’s contextual embeddedness in its sociopolitical environment, and the other providing a glimpse into the inner workings of the organization.

Homer, KA, Cross, MR, and Helms, ER. A survey of resistance training practices among physique competitors during peak week. J Strength Cond Res 38(10): 1745–1752, 2024—Physique athletes are ranked by their on-stage presentation of muscle size, proportionality, and leanness. To acutely maximize muscle size, competitors manipulate resistance training (RT) variables in the days before the contest, commonly referred to as peak week (PW). Resistance training manipulations during PW may act synergistically with nutrition strategies such as carbohydrate loading. However, because little information exists on changes made to RT during PW, the purpose of this research was to determine the current practices of physique athletes and whether competitor characteristics were predictive of the RT variables manipulated. A total of 104 responses to the RT section of a survey on PW nutrition and training were analyzed through a series of multiple logistic regression models to examine the relationship between RT manipulations and competitor characteristics. Furthermore, to determine the magnitude of differences between PW and the week before PW (WBPW) for these variables, a McNemar-Bowker test, paired t-tests, and Wilcoxon signed-rank tests were conducted for nominal, continuous, and discrete outcomes, respectively. For all statistical analyses, p <0.05 was deemed significant. Competitors generally adjusted RT in a variety of ways, where proximity-to-failure was the most frequently manipulated and training frequency was the least; however, no competitor characteristic predicted any of the RT variables manipulated. Within those who manipulated RT variables during PW, frequency, volume, and intensity decreased while repetition ranges of compound exercises increased, empirically confirming that competitors seek to reduce training stress during PW. Such findings can be incorporated in future experimental designs examining the efficacy of peaking strategies to enhance the generalizability of results.

Luders, J, Garrett, J, Gleadhill, S, Mathews, L, and Bennett, H. Comparative effects of complex contrast training and traditional training methods on physical performance within female, semiprofessional Australian Rules Football players. J Strength Cond Res XX(X): 000–000, 2024—This study aimed to explore whether complex contrast training (CCT) would elicit greater strength and power adaptations than traditional (TRAD) training methods using a volume- and intensity-matched design. Fourteen semiprofessional female Australian Football players completed the study. Both CCT and TRAD saw improvements in all performance outcomes: 1 repetition maximum (1RM) back squat (21.3 ± 8.2 and 16.7 ± 6.8 kg), 1RM bench press (5.3 ± 3.6 and 2.1 ± 4.0 kg), 1RM trap bar deadlift (5.0 ± 6.6 and 11.3 ± 2.5 kg), 5 m sprint (0.002 ± 0.09 and 0.02 ± 0.2 s), 10 m sprint (0.04 ± 0.17 and 0.02 ± 0.1 s), 15 m sprint (0.009 ± 0.15 and 0.08 ± 0.2 s), countermovement jump (CMJ) height (230 ± 150 and 340 ± 390 cm), CMJ absolute peak power (158.5 ± 69.6 and 235.6 ± 229.6 N), CMJ relative peak power (3.46 ± 4.1 and 2.68 ± 1.4 N·kg−1)), and plyometric push-up peak relative power (20.5 ± 13.4 and 15.2 ± 13.5 N). There were no between-group differences except for TRAD recording slightly greater improvements in 1RM Trap bar deadlift (Bayes factor [BF10] = 1.210). Complex contrast training completed sessions on average ∼7 minutes quicker than TRAD (BF10 = 5.722), while both groups reporting similar ratings of perceived exertion (RPE) with CCT (±SD) 58.4 ± 6.7 minutes and TRAD 65.5 ± 4.8. Based on the results, CCT training provides the same performance outcomes as traditional training methods across a period of 8 weeks, while taking less time to achieve these outcomes and with similar RPE.

García-Sánchez, C, Navarro, RM, Nieto-Acevedo, R, and de la Rubia, A. Is match playing time a potential tool for managing load in women's handball? J Strength Cond Res XX(X): 000–000, 2024—The aim of this study was to explore the external load experienced by female handball players according to the time played in official matches (≥40, <40, and ≤20 minutes) and in relation to playing positions (backs, pivots, and wings). Twenty-two female players from the Spanish second Division were monitored across 13 matches. Total distance covered, high-speed running distance (HSR), accelerations, decelerations, and PlayerLoad were collected in absolute and relative values using a local positioning system (WIMU PRO, Realtrack Systems SL, Almería, Spain). One-way ANOVA with partial eta-squared and Cohen's d were used to determine the differences between playing time groups and between playing positions. This study revealed that players with more match playing time had a higher absolute values in all external load variables (p < 0.001; very large effects), except in HSR where only wings showed higher values according to the time played (p < 0.001; very large effects). However, these differences between playing time groups disappear when the external load values were normalized according to the effective playing time (p > 0.05). In relation to playing positions, wings covered more HSR/minutes than the other playing positions regardless of the playing time (p < 0.05; large effects). In addition, backs performed more ACC/minutes than wings in the high playing time group and more than pivots in the low playing time group (p < 0.05, moderate effects). In addition, backs performed more DEC/minutes than wings in the low playing time group (p < 0.05, moderate effects). Therefore, handball coaches should consider the playing time as an effective tool to optimize the weekly load distribution.
The Effects of Normobaric Hypoxia on the Acute Physiological Responses to Resistance Training: A Narrative Review

Allsopp, GL, Britto, FA, Wright, CR, and Deldicque, L. The effects of normobaric hypoxia on the acute physiological responses to resistance training: a narrative review. J Strength Cond Res XX(X): 000–000, 2024—Athletes have used altitude training for many years as a strategy to improve endurance performance. The use of resistance training in simulated altitude (normobaric hypoxia) is a growing strategy that aims to improve the hypertrophy and strength adaptations to training. An increasing breadth of research has characterized the acute physiological responses to resistance training in hypoxia, often with the goal to elucidate the mechanisms by which hypoxia may improve the training adaptations. There is currently no consensus on the overall effectiveness of hypoxic resistance training for strength and hypertrophy adaptations, nor the underlying biochemical pathways involved. There are, however, numerous interesting physiological responses that are amplified by performing resistance training in hypoxia. These include potential changes to the energy system contribution to exercise and alterations to the level of metabolic stress, hormone and cytokine production, autonomic regulation, and other hypoxia-induced cellular pathways. This review describes the foundational exercise physiology underpinning the acute responses to resistance training in normobaric hypoxia, potential applications to clinical populations, including training considerations for athletic populations. The review also presents a summary of the ideal training parameters to promote metabolic stress and associated training adaptations. There are currently many gaps in our understanding of the physiological responses to hypoxic resistance training, partly caused by the infancy of the research field and diversity of hypoxic and training parameters.

The energy expenditure associated with body-weight resistance exercises of various movement patterns performed at different durations.J Strength Cond ResXX(X): 000–000, 2024—Although body-weight resistance exercises (BWRE) are popular and effective for body mass reduction and neuromuscular performance, limited information exists regarding their total energy expenditure (TEE). This study determined the energy cost associated with seven BWRE of different movement patterns plank, push-ups, squat, single-leg squat [SLS], forward lunge [FL], burpees, and jumping jacks [JJ] using 2 different durations (T30: 30-second; T45: 45-second) in 10 healthy young adults using a randomized, 2-trial, crossover, repeated-measures design. The level of significance was set atp≤ 0.05. The burpees were associated with the highest and the plank with the lowest intensity (rates of perceived exertion [RPE] and mean heart rate [MHR]) and metabolic load (blood lactate [BL] accumulation, metabolic equivalents of task [METs], and excess post-exercise oxygen consumption [EPOC]) in both trials. In T30 and T45, TEE (kcals per minute) was 11.3/12.6 in plank, 18.6/22.0 in FL, 19.8/21.2 in SLS, 19.9/23.2 in squat, 22.0/24.9 in push-ups, 23.1/22.8 in JJ, and 32.2/40.7 in burpees. Although RPE, MHR, BL, and EPOC were comparable among T30 and T45, METs and TEE were greater in T45. These results suggest that TEE of BWRE ranges from ∼11 to 40 kcals·min−1, depending on the movement pattern and the duration of exercise. This information may be valuable for those using BWRE for body-weight management and improvement of strength performance.

Published: August 2024

The Ministry of Education, Culture, Research, and Technology fostered the Merdeka Curriculum program as a significant endeavor to recuperate from the academic situation after the COVID-19 outbreak. The Merdeka Curriculum has shown better results two years after the pandemic than in the previous academic years. It indicates that learning will be more significant if students independently find ideas through the logical cycle since this can create and bring about scientific attitudes. This research aims to analyze the validity of the guided inquiry-based teaching module on additives to improve students' scientific attitudes. This is an R&D study adopting the 4D model and restricted to the development stage. Questionnaires were used as the instrument for the data collection. The validation included media and content validity, carried out by respectively 1 lecturer as a media specialist and 1 lecturer as a content specialist. The validation results revealed that the developed teaching module obtained 0.95 with very valid criteria from the media specialist and 0.96 with very valid criteria from the content specialist. In sum, the developed teaching module is valid for use in the learning process.
Choice of Arbitrators Regarding Dispute Settlement (Comparing Indonesia and Russia)
Authors: Sidik Jafar , Orlov Oleg , Rozali Asep , Sulistianingsih Dewi
Published: August 2024

Arbitration is a mechanism for resolving civil disputes outside traditional courts, governed by a written arbitration agreement between the disputing parties. Limited to commercial and specific disputes like banking, an arbitration tribunal, consisting of arbitrators, hears and decides these matters. In Indonesia, Law Number 30 of 1999 states that the appointment of two arbitrators grants them authority to select a third. Meanwhile, Russian laws, such as Federal Law No. 382-FZ and Law No. 5338-1, empower the Nomination Committee of Permanent Arbitration to appoint a third arbitrator from an approved list. This article employs a normative juridical method with a comparative law approach to scrutinize the selection and appointment of a third arbitrator according to Indonesian and Russian law. Qualitative analysis reveals that, under certain circumstances, all three arbitrators may be appointed by the Nomination Committee or even the general jurisdiction court, as outlined in the Russian International Commercial Arbitration Court's regulations. The article underscores the importance of providing legal certainty to disputing parties, empowering arbitrators, and avoiding conflicts that could impede dispute resolution. By shedding light on the appointment process, this research aims to contribute to the efficacy of arbitration as a judicious alternative for resolving disputes.
Paradigmatic Problems of Industrial Relation Dispute Settlement on the Perspective of Pancasila Industrial Relations
Authors: Harianto Aries
Published: August 2024

Act Number 2 of 2004 Concerning the Settlement of Industrial Relations Disputes (PPHI Act) has several paradigmatic issues. It has been almost two decades since the PPHI Act went into effect. To adapt to shifting needs and consider changes, amendments have never been implemented. The impartiality of mediators who are not chosen by the disputing parties, the existence of ad hoc judges who are not law graduates, inconsistent standards relating to one's ability to testify in court, government interference, punishments, etc. are the fundamental issues. These facts emphasize that the Pancasila Industrial Relations Paradigm is not followed by the PPHI Act as a legislative ideal. It is not surprising that the justice and certainty that workers hope for are only dreams. Laborers no longer hold a strategic position as actors and objectives of national development because they have normatively become victims of injustice in industrial relations. In addition to identifying the normative inconsistencies between the Pancasila Industrial Relations Principles and the PPHI Act, this research aims to promote a shift toward a more just and equitable approach to resolving industrial relations disputes. This study belongs to juridical normative research by adopting the legal regulations as the object. It applies statutory, conceptual, and comparative approaches. The results show that the PPHI Act has paradigmatic problems. Essentially, it does not adhere to the values of Pancasila industrial relations. Thus, reformulation is highly recommended.

Ensuring the halal status of a product involves utilizing the services of a halal certification body, offering legal protection and confidence in halal product assurance for Muslim consumers. Indonesia is currently in the process of transitioning the certification authority from the non-governmental organization MUI to the government agency BPJPH under the Ministry of Religious Affairs. The halal certification mechanism through BPJPH closely aligns with the established process carried out by MUI. Similarly, Turkey has established the Halal Accreditation Authority (HAK) to guarantee the legal certainty of halal products, providing accreditation services for halal conformity assessment agencies. This study uses a descriptive method with a comparative approach. Focuses on positive legal nor governing the implementation of halal product between Halal Prodyct Assurance  (JPH) and Halal Accreditation Authority (HAK).  The findings reveal that in order to implement the Halal Product Assurance (JPH) system, the Indonesian government established the Halal Product Assurance Organizing Agency (BPJPH). The establishment of a globally recognized halal certification system and the removal of trade barriers in halal goods and services require the effective execution of responsibilities, as demonstrated by Turkey through the activities of the Halal Accreditation Authority (HAK). Turkey's strategy for ensuring the genuineness of halal products involves the Halal Accreditation Authority, tasked with evaluating, accrediting, and supervising the competence of halal conformity assessment bodies. This procedural framework aligns with both national regulations and international standards, incorporating additional technical regulations specified in the accreditation body's implementation documents.

The Indonesian National Police (Polri) is a law enforcement agency that is also tasked with maintaining security and protecting the community through public services within the National Police. However, the fact is that the quality of public services in the contemporary era, especially in the National Police Institution, is still relatively low because it is not in accordance with public service standards. Attitudes that tend to be reactive, rigid, and prone to corruption, collusion, and nepotism (KKN) are obstacles and challenges behind the low public trust in the services of the National Police so far. These various factors then became the government's attention to focus on improving the quality of its services through reform of the National Police bureaucracy. This study uses normative-empirical legal research by analyzing and comparing a regulation as a guideline with its implementation based on data on public service standards in the National Police institution. The research aims to obtain results in the form of identifying obstacles and challenges of the National Police in public services to determine the ideal solution through a strategy to strengthen human resources in reforming the National Police bureaucracy to provide excellent public services as one of the implementations of good government to realize professional services and integrity. Human resources are the most important factor; as an apparatus that will execute state administration, it is necessary to strengthen the quality of human resources as an answer to obstacles and challenges in public services in the National Police institution.

Published: August 2024

This article delves into the issue of legal systems and mechanisms for confiscating assets resulting from corruption. Currently, the mechanism for asset confiscation remains unclear, particularly concerning the procedures for asset restitution, the authorized entities responsible for taking over state assets, the eligible assets that can be confiscated to compensate for state losses, and the institutions authorized to receive, store, and manage state assets resulting from acts of corruption. As a consequence, law enforcement effectiveness has been hindered. Hence, it is essential to establish a fair and definitive regulation for the confiscation of assets related to the criminal act of money laundering arising from corruption by implementing the Asset Confiscation Bill. By implementing clear and comprehensive arrangements for managing confiscated assets, it will foster a professional, transparent, and accountable law enforcement system.

Authors: Nurjaman Daffa Syafiq
Published: August 2024

The study examined the phenomenon of greenflation and its implications for public policy and economic stability. Greenflataion refers to the rising costs of goods and services due to environmental policies and green transitions. This study employed a qualitative research design, analyzing secondary data from academic articles, policy reports, and economic analyses. Findings indicate that greenflation, while promoting environmental sustainability, presents challenges such as increased production costs, inflationary pressures, and social inequality. These outcomes necessitate comprehensive public policies to mitigate adverse economic impacts and ensure equitable green transitions. The study underscores the need for policy frameworks that balance environmental goals with economic stability and social equity.

Authors: Ranteala Anisa Oktaviani , Firdaus Rifqi Ihsan , Nur Mohamad Ichsana
Published: August 2024

This article discusses the development of carbon pricing as a strategy to create a low-carbon economy. Carbon pricing is defined as an economic policy that imposes a cost on CO2 emissions, with several countries, including Japan and Indonesia, having implemented related regulations. The study employs a Systematic Literature Review (SLR) approach using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Challenges in implementing carbon pricing include economic distribution issues, political resistance, and the need for international policy harmonization. Given the urgency of addressing climate change, carbon pricing is a crucial policy instrument for transitioning to a low-carbon economy and achieving environmental sustainability. Special support for industries and vulnerable populations, as well as monitoring and evaluating the impact of the policy, is essential to ensure the effectiveness and fairness of carbon pricing strategies.

Although rare in adults, Wilms tumor is the most common pediatric renal tumor. Treatment typically involves radical nephrectomy followed by adjuvant chemotherapy or radiation, although outcomes differ between children and adults which may be due to challenges in accurately diagnosing these patients. In this article, we present a case report of an adult patient with Jeune syndrome and multiple urologic abnormalities who underwent radical nephrectomy for a large renal mass and was subsequently diagnosed with an epithelial predominant Wilms tumor. Epithelial predominant Wilms tumor may have distinct origins from other Wilms tumor histological subtypes and may incur better outcomes. Herein, we discuss the literature surrounding this rare entity as well as the anticipated treatment course.

INTRODUCTIONBrain natriuretic peptide (BNP) is a cardiac biomarker used in the assessment of heart failure. Potentially, BNP levels can be used to stratify patients with thyroid storm (TS) who are at risk of complications such as heart failure and atrial fibrillation. We compared BNP levels in patients admitted with TS or impending TS (study group) with patients with newly diagnosed hyperthyroidism (control group) and to determine if BNP is a predictor of morbidity and mortality in patients with thyroid storm.
METHODOLOGYThis is a cross-sectional study conducted at University Malaya Medical Centre (UMMC) over one year (January 2023-December 2023). Fifty patients with impending TS/TS (TSG) and fifty patients with newly diagnosed hyperthyroidism (HG) were recruited and their serum BNP was measured. Patients’ morbidity and mortality outcomes were recorded.
RESULTSFT4 and FT3 levels were higher in impending TS/TS (TSG) compared to newly diagnosed hyperthyroidism (HG): [FT4: 64.5 (27.4-129.1) pmol/L vs 30.5 (21.9-131.2) pmol/L, p <0.001; FT3 13.5 (7.9-45.4) pmol/L vs 13.5 (7.9 – 45.4) pmol/L, p = 0.038]. BNP levels were significantly higher in TSG [TSG vs HG:316 (2.0-8148.0) pg/ml vs 27.0 (2.0-310.0) pg/ml, p <0.001]. Those with impending TS/TS experienced higher rates of respiratory failure, atrial fibrillation, sinus tachycardia, and heart failure. In those with impending TS/TS, 80% had elevated BNP compared to 12% in HG. Those with elevated BNP also had significantly longer hospital stays [TSG vs HG: 5 (1-45) days vs 3 (2-7) days, p = 0.019]. Atrial fibrillation and sinus tachycardia were independently associated with elevated BNP detected by multivariable logistic regression. There was no mortality in either group.
CONCLUSIONThis study demonstrated that BNP levels are elevated in impending/thyroid storms and can be potentially used to predict outcomes.

INTRODUCTIONSleeve plus procedures are sleeve gastrectomy variations that include numerous procedures such as SADI-S (single anastomosis duodenoileal bypass with sleeve), loop duodenojejunal bypass with sleeve gastrectomy (Loop DJB) and sleeve gastrectomy plus proximal jejunal bypass (Sleeve PJB). We have performed Sleeve PJB for selected patients in our centre.
METHODOLOGYWe did a retrospective analysis of patients who underwent laparoscopic sleeve PJB in Hospital Raja Permaisuri Bainun Ipoh in 2023. We analysed demographics, weight, BMI and HbA1c. All patients had a sleeve gastrectomy utilizing our standard operative technique. For the proximal jejunal bypass (PJB), jejunum was transected at 50 cm distal to the ligament of Treitz. Subsequently, another 270 cm to 300 cm of jejunum was measured from the divided region and a side-to-side jejunojejunostomy was done.
RESULTA total of 6 patients underwent this procedure. All patients were not amenable to gastric bypass and wanted a more durable surgery in terms of weight loss and metabolic outcomes. Four of them had pre-diabetes and two patients had diabetes based on HbA1c. Cumulative mean age, weight and BMI were 44 years, 109 kg and 44 kg/m2 respectively. The HbA1c for the prediabetes and diabetes group preoperatively were 6% and 8% respectively. Postoperatively at 6 months, the HbA1c was 5.4% and 5.9% respectively for each group. Cumulative postoperative mean current weight and mean percentage of total weight loss (%TWL) at 6 months were 91.5 kg and 20.57%.
CONCLUSIONThis study shows that early outcomes for sleeve PJB are favourable and likely a non-inferior option for patients who are not amenable to a standard gastric bypass.

Authors: Tereshchenko A. S. , Merkulov E. V.
Published: August 2024

Aim. To study the in-hospital outcomes of patients with residual shunt (RS) through the occluder and identify predictors of its formation after endovascular patent foramen ovale (PFO) closure.

Material and methods. We analyzed the data of 276 patients who underwent endovascular PFO closure for the period 2018-2023 at the Chazov National Medical Research Center. All patients underwent a scope of examinations that complied with clinical recommendations. RS in the postoperative period was assessed based on Transesophageal echocardiogram bubble study. Univariate regression analysis revealed RS predictors.

Results. RS in the postoperative period was visualized in 50 patients, who, in terms of the incidence of in-hospital complications, were comparable to 226 patients without RS (p>0,05). Univariate regression analysis revealed the following indicators associated with postoperative RS: implantation of the Amplatzer PFO or Figulla Flex UNI occluder (odds ratio (OR) 8,87; 95% confidence interval (CI): 3,09-25,49), Chiari network (OR 8,26; 95% CI: 1,91-35,81), Olivares-Reyes class >3 interatrial septum aneurysm (OR 2,37; 95% CI: 1,27-4,43), as well as LAVi ≥34 ml/m2 (OR 4,01; 95% CI: 1,33-12,09) (p<0,05).

Conclusion. The use of Amplatzer PFO or Figulla Flex UNI occluders, the presence of a Chiari network, signs of left atrium dilatation, and Olivares-Reyes class >3 aneurysm were significant RS predictors.
