Published: December 2024

Abstract
Construction companies frequently struggle with poor cash flow management of their projects. Financial terms, including retainage, advance payments, and interest rates, significantly impact the project’s cash flow. This study investigates the financial aspects of projects with close beginnings. In addition, considers how to deal with financial deficits by suggesting a multi-project scheduling optimization model to minimize maximum negative cash flow while maintaining maximum profit. Sequential quadratic programming algorithms (SQP) generate workable schedules that optimally use available resources. Several scenarios have been used to test and examine the model. The outcomes indicate a decrease in negative cash flow for company 1 from (-1,852,096) to (-1,817,485) and for company 2 from (-484,524) to (-459,769) in scenario 1. Furthermore, a decrease in negative cash flow to (-1,661,660) alongside a profit of (776,593) for company 1 and a decrease to (-434,970) alongside a profit of (141,228) for company 2 in scenario 2. On the other hand, a decrease in negative cash flow to (-1,698,992) alongside a profit of (786,243) for company 1 and a decrease to (-370,815) alongside a profit of (209,363) for company 2 in scenario 3.
Ensemble Weights-Based Geospatial Model for Optimal Allocation of Wind Turbines: A Case Study in Wasit, Iraq
Authors: Sachit Mourtadha Sarhan 
Published: December 2024

Abstract
Accurate spatial decision-making models are increasingly needed for wind energy planning as the globe rushes towards carbon-neutral energy. This research aims to improve existing decision-making approaches by proposing an ensemble weight-based model for mapping the spatial suitability of onshore wind systems. The model addressed three weighting scenarios: subjective weighting derived from the Analytical Hierarchy Process (AHP), objective weighting derived from the Entropy Weighting Method (EWM), and Artificial Intelligence (AI) weighting based on real-world experiences. The weight sources were harnessed in weighted and fuzzy overlays in a GIS context to create multiple suitability indices. The model was applied to the Wasit governorate in Iraq, considering 10 evaluation criteria and 6 restrictions. The results highlight the dominance of techno-economic considerations, with wind speed being an important factor in all weighting scenarios. Suitability indices suggest that the western, central, and southern areas of Wasit are most suitable for wind farms, with ideal sites identified south of Al-Hay, south of Sheikh Saad, and west of Al-Kut, covering an area of 756 km2 and potentially providing more than 3.5 GW of clean electricity. The findings could encourage wind energy investment in developing countries like Iraq.

Authors: Al-Masraf Harith Mohammed , Al-Attar Tareq Salih , Freyyah Qais Jawad 
Published: December 2024

Abstract
Fracture behavior is an important issue to consider when analysing and designing important concrete structures. Fracture behavior is dependent on the characteristics and materials percentage in concrete. Thus, due to the application of polyvinyl alcohol fiber, this type of concrete’s structure and fracture behavior will differ from normal concrete. This investigation aims to determine some mechanical properties, in addition to the fracture parameters corresponding to low and medium compressive resistance of engineering cementitious composite concrete reinforcing by fiber for notched and un-notched beams, using size effect model techniques in contrast to conventional concrete. The outcomes illustrate an increment in modulus of rupture; both fracture energy and fracture toughness, which were incremented. At the same time, the nominal stress reduction of the notched-beam is superior to un-notched beam. Five mixes for each strength grade were cast to test fresh and hardened properties; the optimum mixture that gave the higher modulus of rupture was chosen for fracture parameters investigations. Two engineering cementitious concrete mixtures containing 1.5% and 2% polyvinyl fiber for grades M25 and M65, respectively, obtained higher modulus of rupture. Geometrically, three (75×75×400) mm, (75×150×800) mm, and (75×200×1200) mm notched-beams were investigated by applying one central point load for testing their fracture toughness, fracture energy, and characteristics length, also the influence of tensile ductility of engineering cementitious concrete. The denser interfacial transition zone of engineering cementitious concrete had the highest fracture toughness and a ductile behavior of mode of failure with a flatter fracture plane than conventional concrete. The higher fracture toughness value was observed on (M25-BC3) and (M65-BC2). Outcomes indicate that conventional concrete exhibited greater sensitivity to size effect parameter due to its poorer tensile ductility than concrete incorporating polyvinyl alcohol fiber.

Published: December 2024

Abstract
The thermal conductivity of materials is characteristic extensively applied across various contemporary domains, ranging from civil engineering to agriculture. The capacity of a material to conduct heat underscores its significance primarily within civil engineering, particularly in energy-related applications. Notably, in the design of energy geostructures, the thermal conductivity of the soil assumes paramount importance. The principle of energy geostructures is to extract geothermal energy, where the base soil works as a heat source. As the thermal conductivity of the ground increases, the amount of extracted energy increases. It can be concluded that the exact determination of the thermal conductivity of the ground has a significant impact on the design of energy geostructures. This article is dedicated to the first detailed measurements of the thermal conductivity of the Bratislava Neogene in five selected localities on samples from depths of 7.1 m to 14.4 m.

Published: December 2024

Abstract
This research presents an advanced computational framework for predicting long-term deflection, crack width, and creep recovery in reinforced concrete beams incorporating recycled aggregate. The study employs a sophisticated nonlinear finite element analysis using Diana FEA software to construct three distinct models based on widely adopted design codes, i.e., Eurocode 2 EN 1992-1-1, fib Model Code (2010), and ACI 209R-92. The numerical models were rigorously validated through comparative analysis with extant experimental data, with a specific focus on examining the effects of creep, shrinkage, and loss of tension stiffening on long-term deflection, crack width, and creep recovery. This investigation specifically addresses the calculation of long-term deflection, crack width, and creep recovery in recycled aggregate concrete beams subjected to sustained loading over a 3000-day period. The study findings indicate that the fib Model Code (2010) is the most reliable for predicting long-term deflection, crack width, and recovery phenomena, consistently aligning closely with experimental results. In contrast, Eurocode 2 EN 1992-1-1 tends to overestimate deflections during early loading. While ACI 209R-92 shows lower error percentages initially, it significantly underestimates deflections by the end of the loading period.
The Interplay Between Economic Diversification, Foreign Direct Investment, and Climate Change in Saudi Arabia
Authors: Louail Bilal , Riache Siham , Alanazi Yazeed Mohammed 
Published: December 2024

Abstract
This study examines the short-run and long-run repercussions of export diversification and foreign direct investment on climate change and greenhouse gas emissions in Saudi Arabia. In addition, the specification includes gross domestic product, total energy use, and urbanization as control variables. The outcomes of the study are as follows. First, the ARDL model provides empirical evidence supporting long-run cointegrating relationships among the variables. Second, export diversification, gross domestic product, and urbanization increase greenhouse gas emissions in the short-run and long-run. Nevertheless, the long-run adverse consequences of these variables tend to be greater than their short-run effects. Third, foreign direct investment inflows reduce greenhouse gas emissions and enhance short- and long-run environmental conditions. Finally, energy use has no significant impact on environmental conditions. These conclusions are robust against many empirical issues, including autocorrelation, heteroskedasticity, misspecification, and normality. The cumulative sum of recursive residuals and cumulative sum of recursive residuals of squares plots confirm the stability of long-run parameters and the validity of the ARDL estimations. The findings offer significant perspectives on measures that should be taken to preserve the environment.

Published: December 2024

Abstract
The construction demolition is non-degradable. Recycled aggregates were utilized to create sustainable products in pervious concrete manufacture. Adding fibers enhances pervious concrete mechanical properties. High absorption of Recycled aggregate (RA) and polyethylene-glycol are used to ensure internal curing. The purpose of this study was to statistically improve the mechanical properties of pervious concrete based on an experimental investigation. Taguchi method was employed to present DOE (Design of Experiment). Five factors in four levels designed by Taguchi provide sixteen mixes (L16 array). The factors were the replacement of coarse aggregates by recycled aggregates, W/C ratio, synthetic macro-fiber, steel fiber and polyethylene-glycol. Designed mixes were prepared. Taguchi’s analysis concluded; that macro-fiber addition has no impact on mechanical properties. Using a ratio of 10% recycled aggregates replacement was the optimum ratio. Taguchi prediction of optimum mixes was experimented with using mixes. Confirmation test results agree with the predicted values within ±10%.

Published: December 2024

Abstract
Efficient transport infrastructure is vital for economic competitiveness, yet landslides pose significant threats to roads, endangering safety and infrastructure. This article focuses on the rehabilitation of landslides using self-drilling anchors. Micropiles, which are reinforced drilled piles offer advantages in areas unsuitable for conventional foundation systems due to their adaptability to challenging terrain and minimal vibrations during installation. Our study focuses on a road site in the Bradl belt, characterized by significantly inclined terrain and medium plasticity clay soils. Using numerical modeling through AutoCad and Plaxis 2D, we evaluate the stability of the slope and the effectiveness of the micropile-reinforced concrete beam system. The φ-c reduction method was employed to assess the safety factor, showing that the spatial arrangement of micropiles enhances slope stability significantly. The results highlighted that a spatial orientation of micropiles improves the structural integrity and safely absorbs impacts, outperforming traditional arrangements. This study underscores the potential of micropiles for effectively addressing landslide threats, offering design, safety, and maintenance advantages.

Published: December 2024

Abstract
The components of Slovakia’s integrated transport infrastructure should be designed, constructed, maintained, and decommissioned at a reasonable cost and quality, respecting the relevant requirements of users, residents in the surrounding area, and the principles of sustainable development throughout its entire life cycle. A comprehensive integrated transport infrastructure must ensure multimodal, interoperable, and safe transport with the lowest possible carbon footprint, focused on regional development and cohesion, with maximum economically feasible minimization of environmental noise induced by traffic. This article provides the basis for fulfilling this premise in environmental noise reduction along the section of the first-class road I/59 from the village of Oravský Podzámok to the village of Likavka, where the current noise levels exceed the permissible values set by legislation. The solution to this problem is expected to be the construction of the R3 expressway, which is being considered in two variants.

Published: December 2024

Abstract
This study investigates the impact of public borrowing and total capital formation on Nepal’s economic growth. The analysis relies on secondary data from publications from the Nepal Rastra Bank and economic surveys conducted in Nepal. The dataset has 34 consecutive yearly data points from 1988/89 to 2021/22. A causal correlational research design is used. It is guided by positivist research philosophy and deductive reasoning. The robust least square method is employed to explore the impact of independent variables. Research indicates that public debt and capital formation favourably and significantly affect Nepal’s economic growth. The study demonstrates that a one-unit rise in public debt and capital formation leads to 0.2881 and 0.6205 unit increases in Nepal’s economic growth, respectively. The positive impact of capital formation is more effective than public borrowing in promoting the economic growth of Nepal. Policymakers should focus on creating a business-friendly environment, enacting growth-oriented fiscal and monetary policies, efficiently allocating resources for infrastructure and technology, and managing public debt prudently to ensure sustainable and equitable economic development.

Published: December 2024

Abstract
The current study aims at conceptualizing time-driven activity-based budgeting and cleaner production (CP) techniques and their integration in achieving sustainable competitive advantage by applying them at Kufa Cement Factory, an economic unit under the Iraqi Ministry of Industry. The research reached several crucial conclusions. Two techniques are integrated as a hybrid model based on time-driven activity budgeting with CP for the reciprocal relationship between contemporary management accounting techniques. This model gets rid of environmental problems, identifies idle energy as output from the time-driven activity-based budget, and uses it for increasing the production, sales, and profitability. The most important recommendation is that strategic thinking should be leveraged for economic unit management and competitive advantage as it is characterized by strong insights, environmental sensing, etc. It can analyze and interpret the information and has a comprehensive knowledge on various aspects of the economic unit and its requirements. The strategies must be defined to leverage the manpower and resources and translate the goals into victory.

Published: December 2024

Abstract
Feline infectious peritonitis (FIP) is a systemic, potentially fatal viral disease of domestic and wild felids. This study demonstrates the pleural and abdominal manifestation of the effusive form of FIP from the clinical and pathological points of view. Two approximately one-year-old cats (male and female) are presented. A set of clinical (haematology, biochemistry), morphological (cytology, necropsy histopathology and immunohistochemistry) and other diagnostic assays (PCR, FIP antibodies detection, protein electrophoresis) were carried out. The results, like lymphopenia, lower A/G ratio, and hyperbilirubinemia are among the most characteristic signs for FIP. The morphology revealed the occurrence of effusions, severe diffuse adhesive pleuritis, icterus, vasculitis/perivasculitis, severe liver and lungs alteration and granulomatous-like reactions with the presence of giant cell type macrophages in the lungs. At the end of this work a list of tests required for FIP diagnosis is mentioned.

Authors: Mudroň Pavol 
Published: December 2024

Abstract
The aim of this study was to determine the effectiveness of formalin footbaths in the prevention of digital dermatitis. The study on more than 450 dairy cows lasted two years with the use of formalin footbaths in the first twelve months. The study showed that there was a decrease in the number of acute digital dermatitis (M2) in the formalin-free period compared to the formalin period (6.49 % and 12.1 %, respectively), with a significant difference between periods (P < 0.05). The number of chronic cases (M3/4) in the formalin-free group tended to be higher compared to the formalin one (22.3 % and 19.9 %, respectively), but the frequencies did not differ significantly between each other. In addition, there was no significant difference in the incidence of digital dermatitis overall. The results show the beneficial effect of footbath skipping on the occurrence of an acute, painful form of digital dermatitis.

Published: December 2024

Abstract
Education is an integral component of society and is inherently linked to the changes occurring within it. This article discusses four significant developments (globalization, localization, individualization, and collectivization) examining both the threats they pose to education and the opportunities they offer. Additionally, it explores how education can navigate its strengths and weaknesses in relation to these societal shifts. A central theme in this article is the content of the curriculum, which may come under pressure if schools respond too impulsively to contextual changes. The analyses in this article are grounded in the right of children to receive adequate education, as outlined in various international treaties and charters. Adequate education is understood as education where the curriculum sufficiently contributes to the achievement of educational goals. It is recommended that, while considering a country's legal provisions, educational objectives be carefully considered and the curriculum, particularly in terms of content, be aligned accordingly.
