Authors: Gavilanes Lisintuña Madison Nohe , Laguapillo Vergara Alexandra del Rocío
Published: January 2025

La enfermedad renal crónica (ERC) se caracteriza por alteraciones prolongadas en la estructura o función renal, con implicaciones graves como hipertensión, enfermedades cardíacas y neurológicas. La fibrilación auricular (FA) es una arritmia cardiaca que muestra una relación compleja con la ERC: la presencia de ERC aumenta el riesgo de desarrollar FA, y viceversa. Varios factores, como la inflamación, el sistema renina-angiotensina-aldosterona, la anemia y las alteraciones electrolíticas contribuyen a esta relación. Ambas condiciones incrementan el riesgo de accidentes cerebrovasculares y mortalidad. El manejo adecuado implica considerar la complejidad de estas conexiones para reducir los riesgos asociados y mejorar el pronóstico de los pacientes.
Urea Treatment and Concentrate Supplementation on the Utilization of Sugarcane Top Pellets in Goats
Authors: Tongol Mae Ann S. , Bestil Lolito C.
Published: January 2025

Sugarcane tops (SCT) are agricultural crop residues commonly used as roughage in ruminant production. However, their utilization is limited due to low protein content and poor digestibility. Biological treatments of high-fiber have been shown to improve the feeding value of crop residues for ruminant production. An experiment was conducted to evaluate the intake and digestibility of SCT pellets treated with urea and supplemented with varying levels of concentrate and the interaction effect of these factors when fed to goats. The dietary treatments considered two factors: factor A (untreated and urea-treated SCT) and factor B (concentrate supplementation levels at 0.75%, 1.00%, and 1.25% body weight [BW]), on a dry matter [DM] basis). Data on intake and digestibility were analyzed using a two-way analysis of variance for a factorial experiment in a randomized complete block design (RCBD). The results indicated urea treatment significantly increased neutral detergent fiber (NDF) intake, with the most notable improvements in NDF digestibility. The intake and digestibility of SCT pellets were enhanced considerably when the pellets were urea-treated and supplemented with concentrates at 1.00% of BW (DM basis). In contrast, untreated SCT pellets showed the highest improvements in intake and digestibility when supplemented with concentrates at 1.25% of BW. Based on these findings, treating SCT with urea is recommended to improve digestibility further when fed to goats. Concentrate supplementation is also highly recommended to enhance the utilization of sugarcane top pellets, with suggested levels of 1.00% to 1.25% for untreated SCT and 0.75% to 1.00% for urea-treated SCT.

Authors: Bhattacharjee Prasun , Jana Rabin K. , Bhattacharya Somenath
Published: January 2025

Unchecked rise in greenhouse gas emissions exacerbates global climate instability, leading to severe ecological disruptions, economic losses, and threats to human health and biodiversity. The sector of electricity is a prominent source of greenhouse gases. Power-generating companies may drastically lessen their fossil fuel consumption by exploring the use of renewable energy sources like wind power. Each year, a noteworthy amount of the functioning time of wind turbines remains unused because of mechanical breakdowns in various of its components. A crucial part of the wind turbine, the yaw bearing enables the wind turbine blades to remain in the correct alignment needed for efficient power generation. In this research, artificial intelligence methods such as the Genetic Algorithm and JAYA Algorithm have been exercised to augment the yaw bearing design. While the Bearing Frictional Torque has been taken into consideration for reduction, Basic Dynamic Axial Load Rating and Static Load Factor have been taken into account for expansion. The Multi-Objective Genetic Algorithm proves to be more advantageous than the Multi-Objective JAYA Algorithm in enhancing the wind turbine yaw bearing's operational dependability.

Published: January 2025

The use of precast structural elements in the construction industry has grown rapidly. This study aimed to determine the first crack value and maximum load of lightweight concrete slabs; the crack patterns of lightweight concrete slabs; and the comparison of the first crack value and floor slab displacement in experimental testing and finite element modeling. This study used the four-point loading which was validated by finite element method (FEM). The experimental test specimens consisted of two variants, namely PN-1 and PN-2 for flexural testing, and PN-A for FEM with 120 mm x 600 mm x 2970 mm in dimensions. The results showed that the displacement values at the first crack for PN-1 and PN-2 were 2.05 and 2.03 mm, respectively. The load capacities for PN1, PN2, and PNA were 24.40, 24.50, and 24.30 kN, respectively, with the first crack occurring at 8.33, 8.34, and 8.33 kN. The initial crack originated at the loading point and subsequently propagated along the tensile plane of the plate. It is recommended to conduct research on the impact of shear connectors in the 3D modeling of flexural plates.

Оценка стоимости публичных акционерных обществ сырьевого сектора в условиях санкционного давления
Authors: Одоевский И.И.
Published: January 2025

В данной статье приводятся результаты оценки стоимости публичных акционерных обществ сырьевого сектора на основе финансовой отчетности с января 2019 года по декабрь 2022 года. Актуальность работы обусловлена резким изменением экономической ситуации с момента начала специальной военной операции, вызванного беспрецедентным усилением санкционного давления со стороны недружественных стран и связанным с этим изменением ситуации на отечественном фондовом рынке. В работе оценка справедливой стоимости компаний проводится методом дисконтированного денежного потока. В качестве денежного потока используется свободный денежный поток фирмы. За ставку дисконтирования берётся средневзвешенная стоимость капитала, для оценки стоимости привлечения собственного капитала применяется модель ценообразования капитальных активов, для оценки стоимости заемного капитала используется синтетический рейтинг. Для оценки роста компании применяются драйверы роста: ставка реинвестирования и доходность капитала компании. В результате проведенной оценки была обнаружена недооценка стоимости отечественных компаний сырьевого сектора на начало 2023 года. Итоги исследования позволяют сделать вывод об устойчивости компаний указанного сектора экономики к антироссийском санкциям на конец исследуемого периода и пессимистичности ожиданий отечественного фондового рынка относительно будущей доходности исследуемых компаний.

This article presents the results of a valuation of public joint-stock companies in the commodities sector based on financial statements from January 2019 to December 2022. The relevance of this work stems from the sharp change in the economic situation since the start of the special military operation, caused by unprecedented sanctions pressure from unfriendly countries and the related changes in the domestic stock market. The fair value of the companies is assessed using the discounted cash flow (DCF) method. Free cash flow to the firm (FCFF) is used as the cash flow. The weighted average cost of capital (WACC) is used as the discount rate. The capital asset pricing model (CAPM) is used to estimate the cost of equity, and a synthetic rating is used to estimate the cost of debt. Company growth is estimated using growth drivers: the reinvestment rate and the company's return on capital. The valuation revealed an undervaluation of domestic commodity sector companies at the beginning of 2023. The results of the study suggest the resilience of companies in this sector of the economy to anti-Russian sanctions at the end of the period under review and the pessimistic expectations of the domestic stock market regarding the future profitability of the companies studied.

MIRCE PROFITABILITY EQUATION
Authors: Knezevic Jezdimir
Published: January 2025

Commonly, maintenance is perceived as “fixing broken things”. As such, it is associated with failure consequences and unplanned expenses, both of which negatively impact business plans or customer satisfaction. However, as failures are an inevitability of the life of any technological system, it would be worthwhile to start looking at maintenance as opportunity for dealing with them and making t positive impact on business plans or
customer satisfaction, while generating profit. Thus, the main objective of this paper is to present the Mirce Mechanics approach to maintenance that is focused on the way that failures, once scientifically understood, could be managed in the way that reduces the number of in-service interruptions and operational costs, which in turn will generate profit for private companies or increases the effectiveness of public services like health, transportation, tourism up to the national defense. Finally, the development of the Mirce
Profitability Equation has been presented in the paper, which is the bed
rock of this approach.
ULTRASOUND IN RELIABILITY

Published: January 2025

Reality in industry, thinking of maintenence approach in many cases, is disproportional with available technologies and knowledge. This situation is decreasing company´s competitiveness or decreasing the possible or projected profit. In the global market, when resources show stable or increasing prices, and final product price drop, future is to be found within the system, and maintenance must be a profit generator. Reliability increase
can only happen once it becomes everyone's concern, not only the concern of the team in charge. Wider acceptance of available technologies inevitably leads to inclusion of larger number of employees in Reliability improvement process, most often through their participation in Condition Monitoring. Ultrasound in maintenance covers wide area of applications and wide range of employees that can use it, depending on their skills and
training applied.

Published: January 2025

Academic staff evaluation poses a unique challenge in higher education system in Bosnia and Herzegovina. The established practice of selfrepresenting the absolute authority in public higher education institutions attenuated by the emergence of private higher education institutions where the employers sought for the results, expressed their own, as well as students’ demands. Encountered with new development in this domain, the members of academic community are facing an unknown and are feared that the application of various models would in fact deteriorate the image of their contribution, the value of their results and credits, and consequently recall or query the benefits at their disposal. This paper provides a detailed overview, expectations and demands for proper practice, and represents an objective model to be used.

A RESEARCH INTO A CONNECTION BETWEEN ENGINEERING STUDENT MOTIVATION AND THE CLIL APPROACH
Authors: Tarabar Aida , Ahmetspahić Adisa
Published: January 2025

The aim of this paper was to investigate the connection between student motivation and Content and Integrated Language Learning (CLIL) approach at the technically-oriented faculties of the University of Zenica. The past few decades have been marked with ongoing debates on what teaching approaches are most motivating for foreign language learners. It has been agreed upon that student-centered approaches are the most efficient ones. CLIL is one of them. Inherently, CLIL uses foreign language for teaching a particular content, in our case – the engineering one. For the purpose of the research, a questionnaire was conducted among the CLIL students, subsequent to their conference - CLIL 2017, which is the last stage of the CLIL approach to English language teaching at the aforementioned faculties. We hypothesized that the CLIL approach bolsters student
motivation for English language learning more than the ex-cathedra approach. The questionnaire proved the hypothesis true as the results indicated high level of motivation in students. In addition, students expressed great satisfaction with the CLIL in terms of its effect on their foreign language proficiency as well as the knowledge in the content matter
related to engineering. Also, students seem to be well aware of the fact that good knowledge of English language and good knowledge of engineering content create a solid basis for employment.
ANALYSIS OF WATER EVAPORATION IN TWIN SCREW COMPRESSORS USING CFD
Authors: Kovačević Ahmed , Rane Sham , Stošić Nikola , Stupple Graham
Published: January 2025

Twin screw compressors are extensively used in applications which require pressures higher then allowable pressure in oil free compressors but would benefit from oil free operation such as food processing, pharmaceutical industry etc. The major limitation for achieving high pressures is due to prohibitively high temperature increase in oil free operation modes. One of the solutions is to inject water in the working chamber which will reduce temperatures and allow for sealing. However, excess water requires a system for water separation and a special treatment to prevent development of diseases caused by bacterial growth. On the other hand, if a limited amount of water is injected in the working chamber which will eventually evaporate and reduce temperature of the system without residuals of liquid water in the system. 3D CFD modelling of such processes allows use of realistic geometry of the rotors and the ports to be captured and the physical effects of fluid thermal interactions and leakage to be analysed. In this paper a CFD model for water injected twin screw compressor that
accounts for evaporation effects has been presented. Empirical form of the Lee evaporation-condensation model for phase change has been applied in the compression chamber using the phase specific mass and energy sources. Calculation of the amount of water required to just saturate the compressed air at delivery pressure is used to set the mass flow rate of water at two operating speeds. The effect of the suction air temperature and relative humidity is studied. Including vapour as a third phase in the CFD model adds a complexity to already challenging deforming grids required for twin screw domains. Hence a mass and energy source formulation is proposed in the presented study to account for the vapour phase and evaporation
effects, thus limiting the number of phases to be modelled. Local drop in gas temperature, distribution of water and regions of evaporation were identified by the simulations. Thermal hot spots on the rotor were located. Reduction in the leakage of gas and its exit temperature was well predicted by the model. Such simplified evaporation model can be further used in the design of water injected screw compressors and extended to predict thermal deformation of the rotors and the housing

HOW TO DETERMINE THE CAUSE AND SOURCE OF HYDRAULIC OIL VARNISHING
Authors: Tič Vito , Lovrec Darko
Published: January 2025

While performing ordinary oil condition monitoring on industrial systems, we can often notice that hydraulic oil has changed its color. The source of the problem can be very difficult to locate and is often consequence of complex chemical processes in hydraulic oil. Finding the root cause of oil varnishing in hydraulic machine design and its operating conditions can be very demanding.
The paper preliminarily presents the most common causes that usually lead to oil darkening. Accordingly, a forensic search method for determining the root cause of oil varnishing is presented and applied on an example of a large hydraulic press system, controlled by a complex valve control system mounted on the control block.

POSSIBILITY OF USING TEXTILE WASTE AS AN ENERGY IN CEMENT INDUSTRY
Authors: Šišić Muvedet
Published: January 2025

The remains of natural and artificial materials in the textile industry are a problem in the technological process because it is a continuous production of waste and related to the need for everyday care. In Bosnia and Herzegovina there are currently no facilities for the material utilization, recycling or reuse of textile waste. Municipal waste disposal cannot be the place for its final disposal. On the other hand, textile waste contains potential for use as an energy source and the cement industry with specific advantages in the use of alternative fuels is the optimal solution for the disposal of waste from the textile industry from the ecological and economic point of view.

Thrombocyte hypoaggregation (hypoaggregability), deserves а special attention regarding bleeding tendency during perioperative dentoalveolar surgery. The diagnosis primary is based on history data of prolonged bleeding and reduced levels of ADP, collagen, and ristocetin, as predictive indicators, directly indicative for high risk of postextraction bleeding (PEB). Usage of tranexamic acid (TXA) in prophylaxis and therapy of (PEB) is a gold standard managing these patients. The aim of this study was to establish the protocol for diagnosing the hypoagreggability and to determine the effectiveness and safety of TXA in managing PEB. Materials and Methods: 64 patients with hypoaggregability were treated at the University Clinic for Maxillofacial Surgery in Skopje,2019- 2024 year. Diagnosis was based on finding of reduction levels for ADP, ristocetin and collagen. Determinate doses of TXA were applicated, side effects were noted and clinical data of location extraction were correlated with the PEB. Results: 88.2% of the patients are diagnosed due to persistent gingival bleeding in the oral cavity and significant indicators for diagnosing hypoaggregabulity were ADP, ristocetin and collagen in 100% of cases. 2/64 patients have side effect of i.v. application of TXA, presented with nausea and vomiting. There were no events of bleeding in 99% of patient using TXA preoperatively.
