Published: January 2025

The development of hospitals in Indonesia is increasing every year. Due to inevitable competition between hospitals, hospital management has to try to improve hospital branding, which can be an opportunity for hospitals to attract new patients and retain patients. In this study, brand benevolence, brand reliability, brand prestige, and brand sincerity were used in the Importance Performance Map Analysis (IPMA) analysis of hospital choice intention. IPMA analysis uses SmartPLS 4.0.9.6 software with online and offline survey data collection methods for all patients who have visited an Indonesia type C private hospital (>100 beds) in the last year. Data collection was carried out in April 2024, obtaining 292 respondents who met the predetermined inclusion criteria. The results show that brand benevolence and brand reliability are included in high importance and high performance, while brand prestige is included in high importance and low performance, which must be considered by hospital management. Meanwhile, brand sincerity is included in the low-importance and low-performance categories. Hospital management must pay attention to brand prestige, which can increase patient satisfaction and hospital revenue in the long term. The study contributes to the understanding of hospital choice intention by highlighting the importance of hospital branding in shaping patient decisions.

Published: January 2025

Type 2 diabetes mellitus (T2DM) poses a growing global health burden. Prevention strategies typically focus on lifestyle modifications or pharmacological interventions, such as metformin, but their comparative efficacy remains unclear. This study aims to evaluate and compare the efficacy of metformin versus lifestyle modifications in reducing the incidence of T2DM among high-risk individuals. A comprehensive meta-analysis of randomized controlled trials (RCTs) was conducted. Systematic searches of PubMed, Embase, and Cochrane databases were performed. Eight RCTs involving 4,684 participants (2,324 in the metformin group and 2,360 in the lifestyle modification group) were included. The primary outcome was the incidence of T2DM, measured as odds ratio (OR) with corresponding 95% confidence intervals (CI). Heterogeneity was assessed using I² statistics. The pooled analysis demonstrated no significant difference in the incidence of T2DM between metformin and lifestyle modification groups (OR: 1.03, 95% CI: 0.64 to 1.65). Substantial heterogeneity was observed (I²=78%, p<0.0001). In conclusion, metformin and lifestyle modifications are similarly effective in preventing T2DM among high-risk individuals. These findings support the use of both interventions, with lifestyle modifications preferred for broader health benefits and metformin as a viable alternative for individuals unable to sustain lifestyle changes. Future studies should explore factors contributing to heterogeneity and assess long-term outcomes.

Authors: Beltrán Carlos , Rivas María Eugenia , Calatayud Agustina
Published: January 2025

El cambio climático (CC) representa uno de los desafíos globales más grandes en la actualidad. A nivel global, las emisiones de dióxido de carbono (CO2) provenientes del sector transporte representan el 25% del total. En el caso de América Latina y el Caribe (ALC), el sector genera el 40% de las emisiones de CO2 de la región, siendo el principal emisor. Asimismo, en las últimas décadas el incremento en la frecuencia e intensidad de fenómenos climáticos extremos como sequías, lluvias y temperaturas extremas ha causado fallas e interrupciones en la infraestructura y servicios de transporte, con altos costos para las economías y poblaciones de la región. ALC se encuentra rezagada en la adopción de políticas para reducir las emisiones y aumentar la resiliencia del sector transporte debido a la falta de información, la falta de priorización en políticas públicas, la incertidumbre tecnológica y los altos costos asociados en un contexto fiscal restrictivo. Este estudio aborda la barrera asociada a la falta de información y análisis sobre la relación entre transporte y CC en ALC que, a su vez, impacta en las demás barreras. El análisis identifica los temas y preguntas clave para contribuir al desarrollo de la investigación académica en transporte y CC en ALC, a través de cuatro etapas: (i) revisión de literatura global y regional; (ii) análisis de prioridades de investigación en la región; (iii) elaboración de propuesta de áreas y preguntas de investigación; y (iv) validación y priorización de las áreas y preguntas propuestas. Los resultados de la identificación y priorización de temas y preguntas de investigación resaltan la necesidad de un enfoque equilibrado que abarque aspectos sociales, económicos y técnicos del transporte y CC en ALC. Las principales prioridades de investigación se relacionan con las temáticas de inclusión y transición justa; los escenarios y trayectorias de descarbonización y adaptación al CC; y el financiamiento de las medidas de mitigación y adaptación, destacando la importancia de abordar las desigualdades, las necesidades de inversión y la coordinación intersectorial.
Beyond pain: The surprising connection between tramadol and depression
Authors: Chen Kaiqin , Wu Haijuan , Fang Yingbing
Published: January 2025

Background: Tramadol, a centrally acting analgesic with a dual mechanism, is frequently prescribed for pain management, including in cancer patients. However, its association with depression, a multifactorial condition influenced by genetic, biochemical, environmental, and psychosocial factors, requires further elucidation. Objective: This study aims to investigate the potential link between tramadol exposure and depression through a comprehensive analysis of pharmacovigilance data and Mendelian randomization methods. Methods: We conducted a retrospective analysis using the FDA Adverse Event Reporting System (FAERS) database, focusing on reports from Q1 2004 to Q1 2023. Data from the EBI and UK Biobank databases were also utilized. Disproportionate analysis methods, including Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), and Bayesian Confidence Propagation Neural Network (BCPNN), were applied to evaluate the relationship between tramadol and depression. Mendelian randomization was performed using the “TwoSampleMR” package in R software to assess the causal relationship. Results: The pharmacovigilance analysis revealed that mental disorders were the most frequently reported adverse events associated with tramadol use, with a significant positive association between tramadol and depression reports (ROR 1.34, 95% CI 1.25–1.44; PRR 1.34, 95% CI 1.26–1.43). Mendelian randomization analysis indicated a significant positive correlation between tramadol exposure and depression (P (IVW) = 0.01). At the same time, our comparative analysis of the risk of depression between tramadol and other opioids found that tramadol was more associated with depression risk than other opioids. Multivariate Mendelian randomization results showed that a causal relationship between tramadol and depression remained when chronic pain was considered an important confounder. Conclusion: The association between tramadol use and depression has significant clinical implications for patient safety and the optimization of treatment strategies. Future research should explore the impact of tramadol on the neurotransmitter system and its efficacy and safety in different subpopulations of patients with depression.

This study investigates the potential of using nanofluids, specifically those composed of water and Titanium Dioxide (TiO2) nanoparticles, to enhance the thermal performance of a double-pipe copper heat exchanger. By incorporating varying concentrations of TiO2 nanoparticles (0.1%, 0.3% and 0.5%) into water, the researchers aimed to improve the fluid's thermal conductivity and viscosity. The experimental results demonstrated that the addition of TiO2 nanoparticles led to a significant increase in the overall heat transfer rate. The highest heat transfer rate was achieved at a nanoparticle concentration of 0.3%, indicating an optimal balance between enhanced thermal properties and potential flow resistance. However, a slight decrease in heat transfer rate was observed at a concentration of 0.5%, suggesting that higher concentrations may not necessarily lead to further improvements. The study further revealed a substantial 23% improvement in the efficiency of the heat exchanger when using the 0.3% TiO2 nanofluid. This enhancement is attributed to the improved thermal conductivity of the nanofluid, which allows for more efficient heat transfer between the hot and cold fluids. In conclusion, the findings of this research strongly suggest that TiO2/water nanofluids can significantly enhance the performance of double-pipe heat exchangers. By carefully optimising the nanoparticle concentration and flow conditions, it is possible to achieve substantial gains in thermal efficiency while minimising potential drawbacks such as increased pressure drop.
Major Findings: This study explored the use of TiO2/water nanofluids to enhance heat transfer in a double-pipe heat exchanger. The addition of TiO2 nanoparticles significantly improved heat transfer, with an optimal concentration of 0.3% leading to a 23% increase in efficiency. However, higher concentrations, while improving thermal conductivity, may lead to increased pressure drop, potentially offsetting the benefits.

Pre-trial criminal proceedings: concept, essence, content and structure
Authors:   Togliatti State University, Kozhevnikov R. O.
Published: January 2025

The paper presents a critical analysis of the current legal regulation of the first part of criminal proceedings indicated in the law as pre-trial proceedings. Having analyzed the legal and regulatory concept of pre-trial proceedings and the types of criminal-procedural activity that make up its content – preliminary investigation and criminal prosecution – the author proposes to enshrine the law enforcement orientation of pre-trial proceedings and its focus on the formation of state prosecution through the investigation and disclosure of crimes. This determines a new understanding of the pre-trial part of criminal proceedings as a set of administrative and investigative activities that are organizationally and functionally separate from judicial proceedings. Analyzing the content of the preliminary investigation and its close objectively existing connection with domestic intelligence activities, the author reveals the interaction existing between them in achieving common goals in the fight against crime, as well as the fundamental differences manifesting themselves in the methods of identifying the circumstances of the crime committed. If the body carrying out domestic intelligence activities solves a crime, i.e. receives actual information about the circumstances of the crime and the persons who committed it, then the preliminary investigation body identifies the circumstances of the crime through collecting a sufficient cumulative accusatory evidence in a way guaranteeing the respect for the constitutional rights and freedoms of the participants in the criminal process. The results of the study allowed determining the place and role of preliminary investigation bodies in the fight against crime, identifying the goals achieved by the investigation body in pre-trial proceedings, justifying their exclusion from the circle of participants in the prosecution and the need to single out one more stage in pre-trial proceedings logically following the preliminary investigation – the stage of criminal prosecution (accusation), within the framework of which the prosecutor’s accusatory activity in pre-trial proceedings begins through the formation of the subject of future legal proceedings – the state prosecution.

The Sustainability of Yemen’s Water Resources: an Annotated Bibliography
Authors: Smith Jade
Published: January 2025

The Republic of Yemen is one of the world's most water-stressed nations. Yemen relies heavily on badly maintained water infrastructure and unsustainable groundwater abstraction to meet most of its water needs. The extraction of groundwater through drilling pumps is considered unsustainable, as abstraction rates are said to be twice as high as the rate of recharge of the aquifers. Women and girls, residents of rural areas, and poorer households are disproportionately affected by water scarcity. Moreover, the conflict that started in 2015 has intensified water scarcity and worsened an already existing cholera epidemic through attacks on water infrastructure and a blockade of Yemen’s coastal ports. Despite having three transboundary groundwater aquifers shared with other countries in the Arabian Peninsula, Yemen has no formal treaties or cooperation agreements that govern their use.

Lichens in quarries of the south tundra subzone of the European North-East of Russia
Authors: Lihanova I. , Pystina T. , Zheleznova G. , Deneva S.
Published: January 2025

The paper presents the first data on the diversity of lichens in building-stone quarries in the vicinity of Vorkuta (south dwarf shrub tundra subzone). The self-regenerative succession in quarries lasts for about 40-50 years. The soil-forming rocks in quarries do not actually differ from those in the background territories by texture but were characterized by a high carbonate content due to calcite. 69 lichen taxa were identified on loamy, gravel-sandy and sandy deposits of the quarries, among them 66 species and three subspecies. The species saturation of lichens at key sites of the quarries reaches 33 species per 100 m2, which exceeds the background value (26 species per 100 m2). This increase is related to the specificity of soil material conditions (presence of carbonates, gravel), vacant places in ecological niches, absence/low abundance of edificatory species, presence of species at different succession stages. In contrast to the background sites, the secondary quarry communities increase in the proportion of epibryophytes among ecologic-substrate group and scaly lichens among life forms. The lichen flora of quarries includes a significant number of calciphile species that makes it peculiar in comparison with the background areas. The quarries have been found for six lichen species included into the Red Data Book of the Komi Republic and its Annex 1.

Published: January 2025

The modern society takes a keen interest in healthy longevity and possibilities of slowing down the age-related diseases. Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that declares itself in adult people (at the age of about 60 years) and is characterized by loss of motor activity, degeneration of motor neurons in brain and spinal cord, and, finally, by respiratory arrest. The disease is currently incurable with its action mechanisms largely understudied but the scientists actively search for therapeutic drugs to further reduce the number of possible complications and delay the negative effects of the disease. Previously, we demonstrated the positive heroprotective potential of black chokeberry (×Sorbaronia mitschurinii) extract on the wild-type line Canton-S on short-term application and observed the increase in the median lifespan of males and females of the elav[c155]-Gal4>UAS-Aβ42 line, which is a model of Alzheimer’s disease in Drosophila. In the present work, we proposed a hypothesis on a possible positive effect of black chokeberry extract at concentrations of 0.1, 1, 5 and 10 mg/mL on the survival of a Drosophila line with the model of amyotrophic lateral sclerosis (with mutation in the Sod1n1 gene). We found that the ethanolic extract of black chokeberry fruits at a concentration of 0.1 mg/mL increased the median lifespan of males by 22 %. When the extract was added to food at concentrations of 1 and 5 mg/mL, we observed a decrease in median and maximum lifespan of males by 14 and 33 %, respectively. However, the ethanolic extract of black chokeberry at any concentrations studied had no statistically significant effect on the survival of females. These results indicate a potential neuroprotective effect of the extract of black chokeberry fruits.
An attribution for two late Gothic central-European panels, in English public collections, depicting episodes from the life of St. Barbara
Authors: Łanuszka Magdalena
Published: January 2025

The article is a result of research on two late gothic panel paintings: The Flagellation of St. Barbara in York Art Gallery and The Martyrdom of St. Barbara (Upton House, Warwickshire), which probably used to be a part of a one retable. Other panel from the same altar would be Christ visiting St. Barbara in Prison (current location unknown, on the Munich art market in 1924). They were all most likely created by Hans Siebenbürger around the same time as the altarpiece of St. Ursula from Lilienfeld Abbey (ca. 1470). The so-called Wiener Schottenmeister (Master of the Viennese Schotten Altar) was a workshop that created the retable to the Schottenstift in Vienna in 1469; according to recent research he seems to be identifiable with the painter Hans Siebenbürger, of Transylvanian origin, who most likely studied in the Nurembergian workshop of Hans Pleydenwurff and later worked in Vienna until he died, before 1483.
The Shadow of God in the Garden of the Philosopher. Parc de La Villette in Paris in the context of contemporary philosophical concerns. Part I
Authors: Wąs Cezary
Published: January 2025

Bernard Tschumi’s project of the Parc de La Villette could have won the competition and was implemented thanks to the political atmosphere that accompanied the victory of the left-wing candidate in the French presidential elections in 1981. François Mitterand’s revision of the political programme and the replacement of radical reforms with the construction of prestigious architectural objects and urban assumptions in the French capital gave Tschumi a unique opportunity to realize ideas that polemicized with traditional forms of social life, questioned the basic principles of architecture and included architectural work in the philosophical disputes over the issues of metaphysics. Tschumi’s theoretical assumptions put forward during the design of the Parc de La Villette highlighted the questions of conflict between the main components of the project and suggested that the intensification of differences was analogous to Derrida’s creation of the concept of différance. It was this philosopher who in a special commentary to Derrida’s project also introduced the concept of maintenant, which aimed at demonstrating that the architect’s polemical inclinations remain in a hidden balance with his inclinations to affirmation of architectural principles. During the discussion between Derrida and Peter Eisenman, who was to take part in the design of the Parisian park, the concept of the chôra was also put forward, which in the course of the debate led to an additional confusion of architectural and philosophical problems.

The process of gasification is well-known; however, to this day, the applications of such facilities, especially off-grid small-scale units for direct electricity and char production, are scarce. In this study, an off-grid fixed bed downdraft gasification unit is studied from the gaseous/solid product character perspective. This unit represents a possible solution for the emerging call for sustainable decentralised energy sources. Softwood chips were utilised in this study, and their conversion into synthetic gas (direct electricity supply) and solid biochar was observed and analysed. The results show promising values of synthetic gas for potential utilisation in different applications outside the direct combustion process, such as microbial syngas fermentation, with a lower heating value equal to 6.31 MJ·m-3. It appears that during the steam activation process of biochar, both high-quality off-gas of more than 70%vol. H2 (excluding N2) and activated carbon of a specific surface area of 565.87 m2·g-1 can be collected. Further investigations have revealed specific degradation of chemical bonds and material morphology changes during steam gasification. The microporous structure and high specific surface area of the material make it an attractive material for further development as an adsorbent in sorption cooling devices. Therefore, the waste generated within the gasification process is minimised, and the potential of the obtained products will be valued in favour of the sustainability of the remote locations.

Background - Social assistance (BANSOS) is aid provided by the government to low-income communities in the form of money, goods, or services. Understanding the allocation and influencing factors of social assistance in East Java is crucial for effective distribution. Mixed Geographically Weighted Regression (MGWR) combines global and local regression models to address spatial variability in the data.
Purpose – This study aims to develop an MGWR model with a fixed kernel weighting function for the social assistance budget in East Java for 2022. The specific objectives are to identify factors affecting the budget and determine the best model that represents these global and local relationships.
Methodology – The study employs the Mixed Geographically Weighted Regression (MGWR) method with a fixed Gaussian kernel to analyze social assistance budget data and economic factors in East Java for 2022. Models OLS, GWR, and MGWR are applied and evaluated using the Akaike Information Criterion (AIC) to identify the best-performing model.
Findings – The MGWR model with a fixed Gaussian kernel is the best for the social assistance budget in East Java, yielding a lower AIC compared to OLS and GWR models. The globally influential factor in this model is economic growth (

The cultivation of male laying chickens still has problems, namely the resulting performance is not maximized. Therefore research using fermented ciplukan plant (Physalis angulata) as a feed additive containing antioxidant compounds that function to improve performance needs to be carried out. This study aims to determine the effect of using fermented ciplukan flour on the performance of male laying chicken. This research was conducted at the Animal Husbandry Field Laboratory of the Faculty of Agriculture, Universitas Syiah Kuala, Indonesia. The material for this research was 100 DOC (Day Old Chicks) male laying chicken MB 502 from PT Japfa Comfeed Indonesia. This research method used a completely randomized design (CRD) with 4 treatments. The treatments were: control/without giving ciplukan (T0), giving 0.5% fermented ciplukan (T1), giving 0.75% fermented ciplukan (T2) and giving 1% fermented ciplukan (T3). Each treatment was repeated 5 times, each repetition consisting of 5 chickens. The parameters measured included ration consumption, body weight gain, final body weight, ration conversion and ration efficiency. Data were analyzed using Analysis of Variance, followed by Duncan's Multiple Range test. The results showed that the addition of fermented ciplukan flour in the ration had no significant effect on the consumption of male laying chicken. In conclusion, real treatment resulted in lower performance compared to commercial rations. However, T1, which is 0.5% ciplukan, tends to produce better performance.

Pakchong elephant grass (PEG) is a super fodder with significant nutritional content and high production levels. The purpose of this research is to quantify the growth and yield of PEG through nitrogen fertilizer engineering with different dosages and repeated fertilization methods. A completely randomized design (CRD) was employed in the investigation, with 4 different levels of urea dosage (100; 200; 300; and 400 N kg/ha). And 10 replicates. ANOVA was used to evaluate the data, and Duncan's Multiple Range Test was then used to determine whether the treatments were substantially different (P<0.05). The findings demonstrated that the addition of nitrogen fertilizer at dosages of 200–400 N kg/ha was better compared to 100 N kg/ha at the end of maintenance (8 weeks after planting) for the quantity of leaves, leaf length, the height of plant, production of both fresh and dry biomass of PEG. There were no significant effect (P>0.05) in nitrogen fertilizer levels at the end of maintenance (8 weeks after planting) for leaf width, leaf chlorophyll content, stem sugar content, quantity of tillers, and the leaf-to-stem ratio of PEG. The research's conclusion indicates that adding nitrogen fertilizer up to 400 N kg/ha is generally safe and feasible for the growth and production of PEG. A nitrogen fertilizer dosage of 200 N kg/ha is optimal to meet PEG's growth and production needs.

The possibility of increasing the mechanical strength of porous materials from sponge titanium powders by two methods has been investigated. In the first case, sintering activation was carried out using alloying additives based on Al, ZnO and TiH2. It was found that the maximum (1.8–1.9 times) increase in strength compared to samples made only from titanium powder is achieved by adding up to 0.5 % TiH2. With the introduction of other alloying additives (Al, ZnO), the mechanical strength increases by no more than 16–20 %. The influence of sintering regimes and atmosphere on the mechanical strength of porous titanium has been studied. It is shown that samples sintered in a vacuum have 1.85–1.90 times higher mechanical strength compared to the same samples sintered in an argon atmosphere. In the second case, to increase the mechanical strength of porous titanium, it was proposed to use bidisperse mixtures consisting of fine and coarse titanium powders. For this purpose, up to 20 wt.% of a fine titanium powder with a particle size of 100–160, 40–100 or <40 μm was added to the titanium sponge powder with a particle size of 630–1000 μm. It was found that the introduction of 10–12 wt.% of the finest (<40 μm) titanium powder leads to a 4‑fold increase in the tensile strength of the porous material compared to porous materials made only from coarse (630–1000 μm) titanium powder of the same chemical composition.

This paper presents the results of a study on thermodiffusion zinc coatings obtained using a technology where zinc dust – waste from hot‑dip galvanizing created during the air blowing of pipes post‑galvanization – is used as the zinc component on steel products, including those with threaded surfaces. The technology involves applying zinc coatings to steel products, including threaded surfaces, through thermodiffusion saturation in a stationary container with a powder mixture consisting of 40 % Znwaste, 59 % Al2O3, and 1 % NH4Cl. This method yields coatings with good appearance, and the desired coating thickness, ensuring compatibility for threading, can be controlled by adjusting the exposure time.
