Ball mill energy efficiency optimization: A lifter face angle optimization approach
Authors: Maregedze L. , Chiteka K. , Masike R. , Kanyowa T.
Published: January 2025

On average, approximately 40% of the total energy consumed by grinding comminution industries is attributed to industrial ball mills, underscoring the urgent necessity to address this energy consumption challenge. This study investigates the influence of lifter face angle variations on the performance of ball mills in comminution processes. Through a combination of Discrete Element Method (DEM) simulations and experimental design, the study explores the effects of lifter face angle on energy efficiency, wear rates, and comminution effectiveness. Findings reveal that smaller lifter face angles result in increased scattering of ore particles within the mill, while larger angles lead to reduced wear and improved grindability of materials. The optimal lifter face angle is identified as approximately 24.8°, falling within the typical range used by industrial ball mill accessories manufacturers. An overall energy saving of 5.89% is achieved by using the optimum ball mill lifter face angle of 24.8°. Recommendations for future research include further exploration of optimal parameters, experimental validation of findings, and the development of advanced modelling techniques. By implementing these recommendations, the study aims to contribute to enhanced efficiency, durability, and sustainability in ball mill operations.
Proyecto de comités de bioética en el primer nivel de atención a la salud en la Ciudad de México
Authors: Vicenteño León Alan Irving , Consejo y Chapela Carolina
Published: January 2025

Los problemas éticos en la práctica cotidiana del primer nivel de atención (PNA) han sido insuficientemente explorados por la bioética. Aunque de forma general impera un consenso teórico que reconoce la necesidad de dicha reflexión, no se ha determinado cómo ponerla en práctica, ocasionando una ausencia de medios de soporte ético y falta de reconocimiento de conflictos tanto por profesionales de atención a la salud como de usuarios en dicho nivel, lo que genera que se resuelvan de forma intuitiva según las capacidades personales. Algunos países, entre ellos España, Chile y Noruega, han establecido comités de bioética exclusivos del PNA y la práctica comunitaria. México cuenta con comités de bioética en los tres niveles de administración pública, no obstante, los comités en el PNA representan menos de 5 % del total y los que existen parten de un enfoque hospitalario-asistencial. Este trabajo presenta el proyecto “Comités de Bioética en el Primer Nivel de Atención” (CBPNA), desarrollado por la Comisión de Bioética de la Ciudad de México con el fin de impulsar comités de soporte ético que puedan integrar las particularidades del PNA al análisis bioético y se puedan añadir al ámbito local de la infraestructura institucional. Los CBPNA parten del enfoque de la atención primaria de la salud para integrar en la reflexión aspectos de ética clínica, de la salud pública y organizacional con el fin de construir una red local con los Comités Hospitalarios de Bioética y Comités de Ética en Investigación correspondientes y promover una cultura bioética de ciudadanía activa en la toma de decisiones en materia de salud.

Authors: Lindawati Ang Swat Lin , Handoko Bambang Leo , Andrian Tommy , Wijaya Harjunadi Geindra , Rombot Olifia
Published: January 2025

Financial performance is another requirement for companies to maintain their image, and good financial performance is the key to the company’s standing. Financial performance is influenced by factors such as leadership from the director or chief executive officer (CEO). This study aims to obtain empirical evidence regarding the influence of CEO overconfidence, female directors, and CEO duality on financial performance. The companies studied are industrial companies listed on the Indonesia Stock Exchange (IDX) from 2015 to 2021. This research uses quantitative data collected from annual reports published by the companies. The sampling technique used is purposive sampling, based on criteria relevant to the research needs. The data analysis technique used is multiple linear regression. The results of the study explain that CEO overconfidence and female directors influence financial performance, while CEO duality has no effect on the company’s financial performance. Gender issues have not yet been included in previous CEO antecedent-based research on financial performance. This is the new finding from our study. In our research model, we included antecedents for female directors.
Kehitysvammaisten kuolleisuus lapsuusiässä
Authors: Similä Seppo , Von Wendt Lennart , Rantakallio Paula
Published: January 2025

Laitoshuollossa olevien kehitysvammaisten elinikä on keskimääräistä elinikää lyhyempi. Kaikkia kehitysvammaisia kattavia elinikätiedostoja on olemassa niukasti. Tässä tutkimuksessa analysoitiin Pohjois-Suomessa vuonna 1966 syntyneiden 12 058 lapsen kuolleisuus 18 vuoden ikään asti. Kaikkien kehitysvammaisten kuolleisuus 18 vuoden seuranta-aikana oli 163,6 /00, noin 7-kertainen normaaliväestöön verrattuna. Syvästi kehitysvammaisten (IQ < 20) kuolleisuus oli peräti 444,4 /00. Sen sijaan lievästi (IQ 50-70) kehitysvammaisten kuolleisuus ei poikennut merkitsevästi normaaliväestön kuolleisuudesta.
Vaikeasti (IQ < 50) kehitysvammaisten korkea varhaiskuolleisuus koostui suurelta osin Downin syndrooma -lasten korkeasta kuolleisuudesta (385/1000 18 vuoden seuranta-aikana). Muiden kuin Downin syndroomaa sairastavien kehitysvammaisten kuolleisuus oli 92,2 /00, yli 4-kertainen normaaliväestöön verrattuna. Kuoleman syistä synnynnäisten malformaatioiden osuus oli 52 % ja infektiotautien 26 %. Vaikeasti kehitysvammaisten korkea kuolleisuus selittyy siis lähes täysin Downin syndroomaa ja synnynnäisiä vaikeita malformaatioita sairastavien korkealla varhaiskuolleisuudella.

Katsaus sisältää esimerkkejä teknologian ja vallan suhteista terveydenhuollossa ja lääketehieteessä tarkastelemalla lääkekehitystä, raskaus- ja synnytyskäytäntöjä sekä niiden muutoksia. Teknologian ja vallan suhde on kaksisuuntainen. Valtaa käyttävät henkilöt ja yhteisöt määrittelevät teknologian tuottamisen ehdot ja sen, kenellä on oikeus käyttää teknologiaa ja millaisissa yhteyksissä sitä käytetään. Toisaalta lääketeollisen teknologian tuottaminen ja käyttäminen vaikuttaa vallan jakautumiseen: toisten valtaa se lisää, toisten vähentää. Katsauksessa tuodaan esiin seikkoja, jotka perustelevat kriittisempää terveydenhuollon ja lääketieteen teknologioiden tutkimusta ja arviointia.

This project evaluated the behavior of the electrochemical corrosion resistance of AISI 304 Stainless Steel as reinforcement in conventional concrete, elaborated based on the method ACI 211.1, with a water/cement = 0.65 ratio. The samples were in the presence of water and a 5% CaCl2 solution for more than 160 days, the first environment representing a control medium and the second representing an aggressive medium. On the other hand, the electrochemical technique of linear polarisation resistance (Rp) was implemented for the determination of the intensity of corrosion current Icorr and the measure of corrosion potencial Ecorr, in accordance with the ASTM C-876-15 method. As a result, Ecorr and Icorr values were obtained, demonstrating a better performance against corrosion in the presence of a high level of chlorides when using AISI 304 Stainless Steel.
Reforming the Parliamentary Threshold in Indonesia's General Elections: A Legal and Fiqh Siyasah Dusturiyah Perspective
Authors: Barqi Suha Yusbairoh , Al Arif M. Yasin , Irwantoni Irwantoni
Published: January 2025

This study examines the issues surrounding the establishment of the parliamentary threshold in Indonesian elections from 2009 to 2024, as well as the urgency of its reform, from the perspective of fiqh siyasah dusturiyah. The study aims to analyze the impact of the parliamentary threshold on the multi-party system and the stability of democracy and to offer solutions based on Islamic legal studies. The research employs a juridical-normative method with both a legislative and conceptual approach. Data were collected through literature studies, including legal documents, scholarly journals, and court proceedings. The study results show that applying the 4% parliamentary threshold in Law No. 7 of 2017 has led to negative consequences, such as the significant waste of valid votes and the limited access of smaller parties to the Parliament. From the perspective of fiqh siyasah dusturiyah, this policy does not fully align with the principle of maslahat, as it creates imbalances in political representation. Therefore, a threshold revision to a more rational figure, such as 1%, is needed to minimize wasted votes and reinforce the principle of democratic justice. The conclusion emphasizes that the threshold size must consider the maslahat (benefit) of society and align with the principles of fiqh siyasah dusturiyah to support implementing a more inclusive and just electoral system.
Legal Reform and Strengthening of The Financial Services Authority (OJK): Protecting Investors From Insider Trading in Indonesia
Authors: Syazali Emir Adzan , Najwan Johni , Muskibah Muskibah
Published: January 2025

This study aims to analyze and critique the legal protections for investors against insider trading practices in Indonesia’s capital market, while highlighting the importance of strengthening the Financial Services Authority (OJK) in ensuring legal justice for investors. Utilizing a normative juridical method, this study employs various approaches, including the statute approach and the conceptual approach. The findings of this study reveal that the regulation of protection against insider trading in Indonesia's capital market remains inadequate due to legal gaps in the Capital Market Law, which has not comprehensively addressed issues, particularly regarding secondary tippees. Thus, a revision of the Capital Market Law is necessary to address these legal gaps by adopting the theory of abuse and regulating secondary tippees. Consistent and strict law enforcement must be enhanced. Furthermore, strengthening the capacity of the OJK is essential, including the use of technologies such as big data analysis and artificial intelligence to detect transaction anomalies more effectively. In addition to strengthening the internal capabilities of the institution, cooperation with other parties, such as law enforcement agencies and international bodies, is also crucial
Javanese Cultural Inculturation in the Depiction of Mother Mary’s Statues: a Semiotic Analysis and Theological Reflection
Authors: Arbi Arwendi Patrik Diego , Kharisma Yohannes Bramanda Ryan , Prasetya Feremenatos Oktafilio Adi
Published: January 2025

Inculturation is one of the crucial aspects in the living out of the Christian faith. Without inculturation, the Christian faith would become alienated from the context of believers’ lives. Conversely, with inculturation, faith becomes more vibrant as it is not only expressed in accordance with the local context, but also touches the concrete lives of the people. This research concentrates in exploring the uniqueness and distinctiveness of the inculturation of four statues of Mother Mary within Javanese culture in several pilgrimage sites and churches. The four statues of Mother Mary are Dyah Marijah Iboe Ganjoeran, Maria Ratuning Katentreman lan Karaharjan in Gantang, Bunda Maria Stella Maris in Pacitan, and Maria Bunda Segala Suku in Jakarta. By using this qualitative method, the research employs literature review, interviews, and field observations. The aim of this research is to analyze the forms of Javanese-styled Mother Mary statues and reflect on them within the framework of theological inculturation. Based on Ferdinand de Saussure's semiotic analysis, it is concluded that the Mother Mary statues are signs that representing her personality. As sign, each statue has symbolic meanings derived from its name/title, accessories, clothing, and body position. The theological reflection also indicates that each statue possesses dimensions of inculturation that align with the local (Javanese) cultural taste. Therefore, the acculturative effort towards these Mother Mary statues further supports the devotion of the faithful to the figure of Mother Mary, as one of the expressions of their faith.

Published: January 2025

Inculturation permeates the life of the Catholic Church since its conception, making it stay relevant and creative with its evangelising mission amidst a multicultural world. This paper is a study of inculturation within the discipline of biblical exegesis. After a brief explanation about the essence of inculturation, it explores some forms of popular intercultural exegesis or contextual hermeneutics which was developed in Africa. One of them is the “four-legged stool” method designed by Elizabeth Mburu. We applied Mburu’s method to interpret the image of the “good shepherd” which was used by Jesus in John’s Gospel narrative (Jn. 10:1-12), a familiar passage to most Indonesian Catholics. Mburu’s method puts the metaphor align with the theological, literary, and historical context of the local reader. In this case, the research considers the meaning of “a good shepherd” understood through the Indonesian mindset. As a result, the biblical metaphor gained extra meaning from native roots.
Educating Compassionate Attitudes: Perkampungan Sosial Pingit as a Mode for Public Theology
Authors: Mahardika Amadea Prajna Putra , Manggala Jakobus Aditya Christie , Irawan Paulus Bambang
Published: January 2025

This paper discusses the concept of public theology, which involves dialogue and engagement with society, aiming for social justice, community welfare, and the common good for the world. It emphasizes the necessity for public theology to address issues affecting the wider community and to use language and logic understandable and debatable by the public. Although aligned with political and liberation theology, public theology tends to be more reformative than revolutionary. The Perkampungan Sosial Pingit (PSP) in Yogyakarta demonstrates concrete involvement in social work, reflecting public theology. This research highlights the engagement of PSP volunteers, the relationship between emotional impulse and compassion, and the impact of social involvement on religion and theology. Furthermore, it shows how social activism and theology influence and enrich each other, providing inspiration for the involvement of young people in social work and public theology.

Published: January 2025

Worship is a respectful statement made by humans to establish a relationship with God, with all spiritual and physical aspects. In reality, the practice of worshiping the supreme reality is only practiced as a habit without meaning. This study aims to explore the relationship between the appreciation of worship in the Eucharistic celebration and Javanese cultural practices, as well as to explore the positive impact of the practice of worship in daily life. This research uses the Interpretative Phenomenological Analysis (IPA) method with reference to the concept of Catur Sembah in the Serat Wedhatama. IPA research explored four Catholic transmigrants in Tugumulyo OKI, South Sumatera. The results showed that the four respondents who lived the sembah were able to have a tolerant attitude, keep other people's feelings and be more tolerant.

Authors: Wang Tongxin Charlotte , Wakshlag Joseph J. , Jager Mason C. , Schwark Wayne S. , Trottier Nathalie L. , Chevalier Jacqueline M. , Pearson Garett , Cercone Marta
Published: January 2025

OBJECTIVE

To compare the pharmacokinetics of cannabidiol (CBD) and cannabidiolic acid (CBDA) in horses and to evaluate the safety of their chronic administration.

METHODS

CBD- and CBDA-rich oil (1 mg/kg) were administered orally twice daily to 7 adult horses over 6 weeks in a randomized, crossover design with a 2-week washout period. A 12-hour pharmacokinetic analysis was conducted on day 1 of each 6-week trial, followed by the measurement of peak and trough concentrations at weeks 1, 2, 4, and 6. The cannabinoids safety was assessed via daily physical examination, periodic bloodwork, and liver biopsy at the beginning and end of the study.

RESULTS

12-hour pharmacokinetics revealed a higher maximum serum concentration (103 vs 12 ng/mL) and greater area under the curve (259 vs 62 ng·h/mL) for CBDA when compared to CBD. Cannabidiolic acid nadir and peak serum levels over time ranged from 46 to 122 ng/mL, which was higher than CBD (12 to 38 ng/mL). Complete blood count and serum chemistry revealed no clinically relevant changes with either CBD or CBDA. No significant abnormalities were detected on liver ultrasonographic and histopathologic evaluation on day 0 and after both phases of the study.

CONCLUSIONS

A dose of either 1 mg/kg of CBD or CBDA administered long term appears safe; however, CBDA serum concentrations suggest superior absorption/retention.

CLINICAL RELEVANCE

Chronic cannabinoid supplementation in horses is safe. Considering the higher absorption of CBDA, its use is recommended to evaluate the therapeutic efficacy of this common hemp derived cannabinoid.
Bronchial vessel density is correlated with airway smooth muscle cell proliferation in horses with mild and moderate asthma
Authors: Millares-Ramirez Esther M. , Dupuis-Dowd Florence , Mainguy-Seers Sophie , Lavoie Jean-Pierre
Published: January 2025

OBJECTIVE

In severe equine asthma, structural remodeling of the airways ultimately leads to bronchial wall thickening and airflow obstruction. Increased bronchial vascularization has been described in horses affected by the severe form of the disease, but whether it contributes to bronchial remodeling in milder forms of asthma remains to be determined. In a blinded, retrospective case-control study, we evaluated the presence of bronchial angiogenesis in horses with mild and moderate equine asthma (MEA) and its correlation to airway smooth muscle remodeling.

METHODS

Endobronchial biopsies from the Equine Respiratory Tissue Biobank collected between August 14, 2014, and May 31, 2019, from 9 horses with MEA and 7 healthy controls were studied. The vascular basement membrane was identified by immunohistochemistry, allowing the measurement of the number of bronchial vessels, vascular area, and mean vessel size by histomorphometry. The correlations between angiogenic parameters, airway smooth muscle (ASM) remodeling features, and airway neutrophilia were studied.

RESULTS

No differences between groups were observed for the angiogenic parameters evaluated. The number of vessels was correlated to ASM cell proliferation in MEA horses (Spearman r = 0.73) but not in controls. Airway neutrophilia correlated negatively with mean vessel size in horses with MEA (Pearson r = −0.83) but not in control horses.

CONCLUSIONS

Major changes in bronchial vascularization do not occur in central airways in MEA.

CLINICAL RELEVANCE

Contrary to previous findings in horses with severe equine asthma, angiogenesis is not a prominent feature of MEA, but it might be associated with ASM remodeling.
Seniors Who Can’t Google Are Extinct Anyway... O. Aging, Dementia and Caregiving in Art
Authors: Jedličková Alice
Published: January 2025

With the increasing life expectancy without a significant increase in health quality, the number of seniors in the population requiring special care due to incapacity following neurodegenerative diseases and the demands on home and institutional care for these persons are increasing as well. What was once an individual family concern has become a major societal challenge. The implications of this issue and the experience of families caring for a senior patient have recently been increasingly reflected in the arts. In this paper, the focus is primarily on recent works of fiction and film from the Czech context (Urban: Dr. Alz, Vlasáková: Těla, Slavík: Tancuj Matyldo); other culturally related works are referred to for comparison. In the enquiry, social contexts and subjects that the artworks represent are examined; we distinguish between those focused on the patient and those tracking the changes in the family, whether they remain in the private sphere or include aspects of institutional care, whether they use the perspective of the patient or the caregiver; and what effects these practices achieve, i.e., how they can contribute to awareness and reflection of the issue and its social processing.

Scale of Resistance of Buildings to Mining Influences – Applicability Assesment Through a Case Study
Authors: NOWAK Katarzyna , STRZAŁKOWSKI Piotr , SZOJDA Leszek
Published: January 2025

This paper presents a case study of the impact of continuous deformations and rock mass tremors on a single-family building, typical of Upper Silesia. In the areas subjected to the influence of ground deformation, a point method for assessing the resistance of buildings to these influences has been developed by the Central Mining Institute. As part of this method, the geometric parameters, structure, materials and technical condition of the facility, as well as the ground on which the building is located, are taken into account. A case study considers a building being simultaneously subjected to continuous deformations and mining tremors. The object’s resistance is assessed according to the point method and its technical condition is assessed after revealing the influence of ground deformation. This is used to assess the validity of the point method for the building. On the basis of the analyses of the state of deformation and the impact of tremors, conclusions are drawn regarding the need to make changes to the scale used to assess the category of resistance of buildings to the effects of continuous deformation.
Dynamic Tests of Pony Truss Railway Bridge Under Normal Operation
Authors: PRADELOK Stefan , POPRAWA Grzegorz
Published: January 2025

The article describes the application of dynamic tests during normal operation in assessing the technical condition of the railway bridge on the Nysa Łużycka River. The investigated structure consists of six steel pony truss spans. Operational modal analysis was used to identify dynamic parameters. The results obtained were applied to verify the numerical model used in the assessment process of technical condition and in determining the current load capacity of the structure created in the 1950s. The experiment conducted allowed us to observe the dynamic response of the pony-truss bridges. The study demonstrated that dynamic tests during normal operation and the use of other available environmental excitations could complement other non-destructive diagnostic methods. This proves that we can obtain useful information about the dynamic properties of a structure without closing the traffic and without the application of the ordinary dynamic test load.

Authors: WALENTYŃSKI Ryszard
Published: January 2025

The task of analysing shocks in areas of paraseismic mining activities is one of the important engineering tasks. Acceleration measurements should be integrated to receive velocity and displacement functions. Sometimes, numerical algorithms produce wrong results. This paper proposes a semi-analytical approach to this problem. The algorithm has been implemented within the Mathematica system. Moreover, this method has been applied to integration of the equation of motion.
Localization of Brutalist Architecture in Post-War Turkey: Three Unique Examples from Istanbul
Authors: BALCI ÖZTÜRK Özlem , ŞENYURT Oya
Published: January 2025

Brutalism, a revision of Modernism, originated in England in the 1950s and spread rapidly globally. This intercontinental expansion has led to distinctive local diversity in different geographies, from Europe to the America. Concurrent with global examples, brutalist buildings began to appear in Turkey in the early 1960s. Notably, in Istanbul, Brutalism has managed to localize and create unique examples. This study investigates the transition of Brutalism between geographies and its localization in Turkish Architecture. This study analyzes brutalist and brutalist-influenced structures in Istanbul. According to the results of this analysis, the unique examples of Manifaturacılar Retail Center, Istanbul Reklam Building, and Istanbul Officers’ Club are examined based on Reyner Banham principles to shed light on this localization in architecture. This study aims to provide an intercontinental case study of the integration of the expansion of global currents with cultural diversity. In this context, this study examines how Brutalism has been localized in Turkey and aims to expose unique examples that have yet to appear in the relevant literature.
The Reuse of Ceramic Materials in Architectural Design – Case Studies
Authors: MAGOSZ Agata
Published: January 2025

The global construction industry, notorious for resource consumption and waste production, has found an interest in the circular economy and sustainable development practices. This paper examines the reusability of ceramic building materials within architectural designs, emphasizing the principles of the circular economy and the 3R concept with a special focus on reuse. By performing a comparative analysis of 26 buildings the research explores the strategies for reusing ceramic materials. It categorizes reuse into two approaches: re-creation and transformation, while also considering the prevention of materials from becoming waste. The analysis scrutinizes the origin and function of materials, their placement in new designs, and the reasons behind their reuse. The study delineates recurring design patterns of using reclaimed building materials. It also categorizes three main approaches to incorporating reused elements into new structures.
The Factor Determining Effective Modelling of the Urban Spatial Transformation Process Based on Temporary Use
Authors: SZATON-ORLIŃSKA Karolina , OPANIA Szymon
Published: January 2025

The research involves analysing strategic models of urban spatial transformation processes in cities using temporary use as a significantly supportive tool or as the core of the transformations. The scope of the research includes identifying effective transformation models through the verification of cases based on established criteria and conducting detailed studies of selected cases to highlight the process elements, analyse their relationships, and assess the role of temporary use. The research method relies on critically comparing and analysing chosen cases. As a result, we have identified fundamental criteria that indicate the application of temporary use as part of a broader transformation process, along with supplementary indicators and characteristics that impact the effectiveness of the conducted transformations. These indicators can help model transformation processes based on temporary use. The research holds particular significance in utilizing temporary use within a broader, integrated urban transformation process that goes beyond a one-time intervention.
Effect of Silt and Clay Fraction Content on Frost Heave of Fine-Grained Soils
Authors: WITEK-ZIELONKA Kinga , PARYLAK Krzysztof , KILIAN Wojciech , ZIELONKA Łukasz
Published: January 2025

Frost heave in soils is a significant problem of geotechnical engineering. Despite the introduction of numerous simplified frost susceptibility criteria, there is still no clear relationship between the particle size distribution and their frost heaving susceptibility. Therefore, an experimental attempt was made to link the graining features of the four soils with the mechanisms of the formation of frost heave. The main aim of the study is to determine the influence of the content of silt and clay fractions on the height of the frost heave. The tested soils were characterized by a varied content of the silt fraction, which, together with smaller ones, amounted to 30%, 40%, 50% and 70%, and a variable content of the clay fraction amounting to 0%, 0%, 21% and 5% in individual soils, respectively. For the purposes of the experiment, a test stand was constructed that allows for testing 6 identical samples at a time. The tests were carried out in an open-system test, i.e. with the possibility of water flowing into the freezing zone. The total freezing process was carried out at -10°C and lasted 160 hours. On the basis of the obtained results of the increase in the height of the samples, it was shown that the silt with the highest total content of silt and clay fractions of 70% shows the highest frost heave and the smallest increase in the height of the samples in the freezing process is shown by sandy silt with the lowest sum of both these fractions. On the basis of the analysis of the results of the tested soils, it was found that the height of the frost heave was influenced by the presence of the clay fraction, but in connection with the presence of the silt fraction. In the frost heave soils, the content of the silt fraction influences the amount of the frost heave to the extent of more than two times smaller than the content of the clay fraction.
Optimization of the suspension procedure by Box-Behnken design for the determination of manganese, iron, and zinc in zeolite clinoptilolite with the TXRF system and insight into its antioxidant properties
Authors: Jablan Jasna , Štefan Maja Bival , Paler Dario , Kamenski Emma
Published: January 2025

Zeolites are a large family of minerals and the most studied is the naturally occurring clinoptilolite. They possess anti-inflammatory, antioxidant, and detoxifying properties which makes them valuable for medicinal use. Element analysis of zeolite’s composition is necessary for its precise chemical characterization, and within this work development of a suspension method for the determination of manga nese, iron, and zinc by total reflection X-ray fluorescence spec-trometry (TXRF) was presented. The Box-Behnken design based on the response surface methodology was applied to determine the optimal sample preparation conditions. The significant variables such as sample amount, volume deposition, and dispersant were selected as critical variables. Based on the results obtained, sample suspensions were prepared by weighing 10 mg of the sample and adding 1 mL of 5 % Triton X-100 with 10 mL Ga as internal standard and deposition volume was set at 10 mL. The results obtained with TXRF were comparable with those obtained with the FAAS method, indicating that this technique can be used instead of the conventional methods. Using the best analytical conditions, the limits of detection for trace elements were in the range of 0.2–0.6 mg kg–1. Trueness and precision of the results, evaluated by CRM sample analysis, were in most cases acceptable with recoveries values in the range of 104.9–111.4 % and relative standard deviations of 2–10 % (. = 6). Zeolites showed no ability to quench free radicals nor the ability to influence dietary antioxidants.

Authors: Kozjek Tatjana , Pečarič Mirko
Published: January 2025

The governance of any organisation comprises a system of rules, practises, and procedures that guide and control the organisation. The case study examines the processes, procedures, activities, and problems of decision-making at the level of Slovenian ministries in terms of compliance with strategic documents, action plans, programmes, and other ministerial documents. The research focussed on the administrative/implementation level, where planning, control, impact assessment and timely reaction to deviations are of particular importance. The aim was to analyse the coordination between ministries, departments and public institutions. The results show that there is no system and that the documents on which the institutions work are inadequate.
The Effect of Employee Income on Absence from Work Due to Illness
Authors: Beran Vlastimil
Published: January 2025

Illness, or the medical treatment of a family member, comprises an inherent part of human life, the occurrence of which often prevents employees from attending work. This article analyses the relationship between absence from work due to illness and the amount of an individual’s income. The article further monitors the impact of the Covid-19 disease and whether it affected absence from work. In theory, it can be assumed that persons with lower incomes have higher absence rates. The data, which was analysed for the period 2014–2022, was provided by the Ministry of Labour and Social Affairs of the Czech Republic. Basic descriptive statistics and methods of structural breaks were applied to determine the underlying trends. It is possible to state that absenteeism decreases from the 6th decile and is lowest in the highest decile of the working population. Covid-19 was found to have significantly affected employee absenteeism.
The early limnological tradition as an ecological resource: a historical account between Europe and the United States of America on the concept of the organism-environment relationship
Authors: Pireddu Pier Luigi
Published: January 2025

This paper proposes that lake ecosystems have historically provided fertile ground for the advancement of ecological concepts. It argues that foundational ecological ideas, such as ecosystems and the organism-environment relationship, have their roots in limnology, the scientific study of lakes. In other words, these concepts were developed by approaching lake ecosystems as primitive ecological models. To illustrate this point, it examines the scientific endeavors of François Forel (1841-1912) in Geneva, Switzerland, and Stephen Forbes (1844-1930) in Illinois and Wisconsin, United States. Both were pioneering figures for the development of the limnological or, even more broadly, the ecological discipline. Curiously, they contemporaneously developed their respective scientific accounts in two different scientific traditions.
Provoking and Foreseeing Sudden Changes in the Workability of Pumped Concrete

It was attempted to provoke and foresee sudden loss of workability during concrete pumping through a series of full-scale tests. Batches of 2 m3 concrete were produced at a ready-mix plant, transported by concrete trucks and pumped by industrial pumps, to reveal sudden loss of workability. Different mix designs, extension hoses and pump setups were utilised in a six series experiment. An experimental procedure for measuring loss of workability at a laboratory scale was developed due to the standardised procedures for slump measurements camouflaging loss of workability. The experiments revealed that pumping through a boom seems to have a positive effect by reducing probability of sudden loss of workability. Furthermore, the fine aggregate seems to have a strong influence on the phenomenon, especially in the range of 0.25 mm to 1 mm.

The construction industry is pursuing the reduction of CO2 emissions and the development of lowcarbon concrete. LOIKKA research project was initiated in Finland with the aim to reduce the CO2 emissions of concrete manufacturing by 50%. The use of blast furnace slag was seen as the most competitive way to significantly reduce CO2 emissions of concrete. However, incorporating slag in concrete can lead to durability complications, particularly concerning salt freeze-thaw resistance. This study investigates the effects of slag content, carbonation/ageing, and pre-curing conditions on the freeze-thaw and salt freeze-thaw resistance of concrete. Additionally, it evaluates the compressive strength development and porosity differences of test concretes. Slab tests were conducted to determine the surface scaling and internal damage resistance of concrete specimens. The results showed that high slag content and carbonation reduced salt freeze-thaw resistance. The incorporation of 50% slag content as the cement clinker replacement is considered critical. An increase in slag content led to a decrease in the compressive strength at 7 days due to the low reactivity of slag but achieved the highest compressive strength at 91 days with 70% slag content. These insights contribute to our understanding of the durability properties of concrete incorporating slag.
Automatic Measurement Techniques for Compositional Properties of Fresh Concrete: Focus on Water/Cement Ratio and Air Content
Authors: Ojala Teemu , Punkki Jouni
Published: January 2025

Current testing methods for fresh concrete are time-consuming and operator-dependent and, thus, should be replaced with automatic testing methods. This study investigated automated measurement techniques for determining water/cement (w/c) ratio and air content in fresh concrete, addressing this need for more efficient and continuous quality control. The research compared microwave absorption (MWA) and time-domain reflectometry (TDR) techniques for w/c ratio measurement as well as acoustic wave propagation (AWP) technique for air content measurement, against the reference testing methods. Laboratory investigations were conducted on various concrete mix compositions. Results showed that MWA and TDR techniques demonstrated a good correlation with reference methods for w/c ratio (R² = 0.808 and 0.858, respectively), but were sensitive to air content variations. The AWP technique for air content measurement showed a moderate correlation with the pressure method (R² = 0.654 for static measurements), with accuracy influenced by concrete consistency. The study highlights the potential of these automated techniques for real-time concrete quality control, while also revealing limitations related to mix composition variations and calibration requirements. These findings contribute to the ongoing development of more precise and reliable automated measurement systems for fresh concrete properties, supporting the move towards advanced quality control methods.

Published: January 2025

The conflict and relations between Poland and Ukraine are an important aspect of the geopolitical reality of Central and Eastern Europe. In the context of changing political, economic and social dynamics, the media play a key role in shaping public opinion and reporting on events between these two countries. In the article, we will analyse the role of the media in the context of the political and economic relations between Poland and Ukraine, following Russia’s invasion of Ukraine. We will focus on how the Polish media present the conflict, and its impact on cooperation and interactions between the two countries. The article will also present the potential impact the media representation of the conflict may have on international relations, including diplomacy, economic cooperation and regional integration. By analysing this issue, we will try to determine the role of the media as a factor influencing the perception and understanding of the relationship between Poland and Ukraine and the need for a critical approach to media narratives in the context of building common understanding and cooperation between the two countries. The content analysis will cover selected issues of weekly magazines representing various sides of the political scene: Polityka, Newsweek and Sieci.
