Potential for preventing the risk of social exclusion of children in Early Childhood Education and Care in Croatia
Authors: Bouillet Dejana , Majcen Sandra Antulić 
Published: January 2023

Abstract
This study assumes that preventing the risk of social exclusion (RSE) of children, in the context of ECEC, entails guaranteeing ECEC availability and pedagogical practices that provide children with the necessary skills for healthy and successful development. This can be achieved by strengthening the protective factors in the child’s surroundings. The overall research goal was to determine the accessibility and describe the quality of attendance of children at risk of social exclusion in the Croatian ECEC system. The sample consisted of 3,500 children from 66 ECEC facilities, or 6% of all children aged 5 to 7 attending ECEC programs at that time, from 10.4% of all the ECEC facilities operating in Croatia. Data were collected through a questionnaire to assess the etiological and phenomenological aspects of RSEs among early years and preschool age children (ECEC teachers’ version). The research confirmed that RSEs did influence the children’s ECEC attendance. The greatest obstacles to accessibility of ECEC are risk of poverty and minority ethnic identity of children. Inconsistencies in the quality of the Croatian ECEC system are explained as a missed opportunity for the potential of ECEC to prevent RSEs.
Arts-based critical service-learning experiences as transformative pedagogy
Authors: Jacobs Rachael Frances 
Published: January 2023

Abstract
Initial teacher education programs regularly engage students in service-learning programs, providing an additional pathway to personal, professional and pedagogical transformation in their learning journey. One of those pathways is through service-learning placements in community arts projects. This paper reports on a study of arts-based service-learning programs at two universities. Eight initial teacher education (ITE) students were interviewed after their placements and a number of key themes emerged. These include the importance of productive discomfort as part of the service-learning experience and transformative pedagogy resulting from the art-based experience. This paper also explores some critiques of traditional service-learning models that have opened spaces for critical service-learning approaches. The analysis of ITE students’ narratives led to findings about the path of transformation from traditional to critical service-learning approaches through arts-based projects, an area which has been largely unexplored in previous research. The paper concludes with discussion of future avenues for related research that orientate service-learning in the arts towards social and creative justice.
Implementation of the legal framework for inclusive education in Portugal (Decree-Law 54/2018) – A qualitative assessment by primary and secondary school teachers
Authors: Ferreira Marco , Reis-Jorge José 
Published: January 2023

Abstract
Successful inclusive education requires school transformations and changes to the education system. In Portugal new legislation passed in 2018 (Decree-law 54/2018) brought a new perspective in inclusive education for all educational agents. Three years later, it is essential that the legislation is evaluated by the teachers implementing it. Forty-three primary and secondary school teachers and two coordinators of multidisciplinary teams providing inclusive education support were the participants of our study. The data collection instruments were a questionnaire and interviews. This study values the participants’ narratives, highlighting the new concepts and attitudes required for the implementation of the new inclusive education legal framework in Portugal. The results of the thematic analysis were organized around four key themes: 1. Theoretical representations; 2. Practices; 3. Challenges; and 4. Training. It is also worth noting the notions of collaborative work, the need for reflective teachers and the development of learning communities to support the implementation of the new legislation.
Determination of the Number of Required Charging Stations on a German Motorway Based on Real Traffic Data and Discrete Event-Based Simulation
Authors: Witt Andreas 
Published: January 2023

Abstract
To make travelling with electric vehicles (EVs) over long distances as convenient as travelling with traditional vehicles, charging stations along motorways are necessary. Furthermore, waiting times for free charging points must be short to enable a fast onward journey, and this also on days with heavy traffic volumes. To determine the required number of charging stations in more detail, a model was created that simulates the process of arriving and leaving cars at a charging park based on real traffic data. For the traffic data, a location and date in the Munich region were chosen that represent a peak demand and thus a “worst case” scenario. The ability to cover such scenarios as well seems to be important because otherwise severe congestion with long waiting times would appear on days with heavy traffic, which would make the use of EVs very unattractive. It turned out that 150 to 600 charging stations – depending on the considered scenario – would be necessary to charge proportions of 10% to 20% of all passing cars.
Effect of Set Accelerator on Capillary Suction and Porosity of Concrete – Cast Samples with Constant Water/Binder Ratio
Authors: Trussell Nicholas , Cepuritis Rolands , Jacobsen Stefan 
Published: January 2023

Abstract
Alkali-free set accelerators are added at the nozzle to ensure rapid set of wet sprayed concrete. The accelerator affects the strength development, porosity and transport properties, and hence the durability, of the sprayed concrete. We developed a method to cast samples with varying set accelerator doses to measure the effect of the accelerator on porosity, but with a constant effective water/binder ratio of 0.45 for each accelerator dose. Six cylinders of concrete were cast with set accelerator doses of 0, 2, 4, 6, 8 and 10 % of effective binder mass. High workability was achieved to enable mixing before rapid stiffening occurred, though this high workability led to some aggregate settlement in the cylinders. Porosity was measured by capillary suction on dried specimens of hardened concrete and subsequent pressure saturation of macro pores (PF test). The samples cast with higher doses of set accelerator had higher suction porosities and higher rates of capillary suction. Using a modified Powers equation gave very low calculated degree of hydration values for concrete with set accelerator, indicating that the equation is not applicable for concrete with set accelerators, due to the higher suction porosity in accelerated matrices, caused by different hydration products.
Failure Mechanisms of Fibre Reinforced Shotcrete: Numerical Simulations Considering Local Variations in Thickness and Bond Strength
Authors: Sjölander Andreas , Ansell Anders 
Published: January 2023

Abstract
Fibre-reinforced shotcrete is the most common support method for hard rock tunnels in the Nordic countries. The design of shotcrete is often based on empirical methods or simplified analytical equations, which neglect variations in mechanical properties and shotcrete thickness. Data collected from the field shows that significant variations in shotcrete thickness and bond strength should be expected during tunnel construction. However, how this affects the structural behaviour and capacity of the shotcrete lining is unknown. Moreover, the design philosophy for shotcrete assumes that the primary failure modes of shotcrete, i.e. bond and flexural failure, can be treated separately. This was derived based on observations of experiments in a laboratory environment. Therefore, the focus of a finalized doctoral project was to develop a numerical framework to simulate the structural behaviour of fibre-reinforced shotcrete in interaction with hard rock and rock bolts. The effect of variations in shotcrete thickness and bond strength was studied through numerical simulations to increase the understanding of its effect on the failure load of the lining. The results indicate that the most important parameter is the mean value of the shotcrete thickness and bond strength around a narrow perimeter of the block.’

Published: January 2023

Abstract
This manuscript presents preliminary results on the cement paste potential, with and without carbon nanomaterials, to heal high-temperature cracks. Cement paste beams were subjected to thermal loading of 200°C and 400°C after 28 days of water curing. High temperature caused the formation of microcrack networks on the specimen’s surface. Self-healing was achieved by exposing the cracked samples to cyclic water immersion. The efficiency of the process was evaluated based on the crack closure and mechanical properties recovery after 24 days. The results indicated a distinct dependence of the healing on the loading temperature. Carbon nanotubes had a positive effect on self-repair efficiency.

Published: January 2023

Abstract
This research study explains the design and performance of a Static VAR Compensator (SVC) coupled Hybrid Distribution Static Compensator (DSTATCOM) for low voltage power distribution system (PDS). A comparative analysisis done between Voltage Source Inverter (VSI)-based DSTATCOM and SVC Hybrid DSTATCOM using Jordan Least Mean Square (JLMS) algorithm to alleviate the shunt-related power quality (PQ) glitches. The specific design is obtained as compared to the existing neural network toolbox algorithm to improve the estimation speed and accuracy. The main objective is to extract the tuned weighted values of fundamental active and reactive power components of distorted load currents for the switching signal generation using an adaptive JLMS algorithm.Several functions of DSTATCOM and hybrid DSTATCOM using this JLMS controller are showcased for harmonics curtailment, power factor (p.f.) improvement, load balancing, voltage regulation, etc. Simulation results on an SVC Hybrid DSTATCOM have shown an acceptable level of performance under unbalanced loading situations. Finally, some comparative results are provided to validate the feasibility and effectiveness of the suggested topology.

Published: January 2023

Abstract
The presented study deals with the space located in the attic of an older building after reconstruction. Originally, the attic space was not used, as it did not have sufficient headroom. The reconstruction was designed in such a way that the entire original pitched roof was gradually raised by 1.2 meters in parts, creating a full-fledged space under the pitched pitched roof. The visual connection of the interior space with the exterior was ensured by continuous strips of vertical windows around the perimeter of the building, each window measuring 600x600 mm. The space is also illuminated by several skylights at roof level, which, although they ensure sufficient penetration of daylight from above into the interior, at the same time allow for considerably unpleasant overheating. The task was to find a way to optimize the size of transparent surfaces and determine the accumulation of building structures in order to achieve an acceptable cumulative effect of daylight and overheating, i.e., permissible increase in indoor air temperature in summer. It means trying to theoretically design a suitable and comfortable interior space in the attic in an already existing building.
Coconut Oil as Bio-based PCM: Characteristics and Compatibility with Plastics
Authors: Ostrý Milan , Bantová Sylva , Řezáčová Veronika 
Published: January 2023

Abstract
The current use of buildings is facing an unprecedented increase in energy costs, especially in the European Union. The energy costs can be reduced by energy savings and by increased use of renewable energy represented mostly by energy converted from solar radiation. When solar energy is considered to be utilized in buildings, the mismatch between energy availability and energy demand must be solved by energy storage. This paper describes the principles of the use of latent heat thermal energy storage and the possibility of using bio-based phase change materials as heat storage media. Because the latent heat storage media undergo a change of phase during the charging and discharging, proper encapsulation is necessary. The paper presents the main findings of a study focused on the compatibility between coconut oil and selected plastics as materials of encapsulation. The compatibility of selected plastics and Coconut oil was evaluated by laboratory experiment based on the immersion of plastic samples in coconut oil and calculation of change in weight of samples within 17 weeks lasting test. The negligible weight changes were occurred for polycarbonate and polyethylene terephthalate which proves excellent compatibility with Coconut oil.

Authors: Nasreddine Diaf , Mustapha Hidjeb , Khaled Boudjellal , Mohamed Boudiaf , Ihcene Lamri 
Published: January 2023

Abstract
This work investigates the behavior of a silty clay stabilized with 3, 6, 9, and 12 % of ground granulated blast-furnace slag (GGBS), respectively, and 1 % of quicklime used as an activator. The influence of the composite (Quicklime - GGBS) on the immediate behavior of the silty clay is studied by examining the Atterberg limits, the maximum dry density, the optimum moisture content, and the immediate bearing index. The evolution, at different curing periods (1, 7, and 28 days), of the mechanical characteristics of the treated soil, namely unconfined compressive strength, cohesion, and internal angle of friction is also studied. The increase, up to a dosage of 9%, of the GGBS content, leads to an increase in the optimum moisture content, the immediate bearing index, the unconfined compressive strength, and shear strength parameters. Paradoxically, a decrease in the plasticity index and the maximum dry density was observed.

Published: January 2023

Abstract
This paper aims to present a deflection prediction model of Near Surface Mounted (NSM) Reinforce Concrete (RC) beams using the Fuzzy Logic Expert System (FLES) with different types of membership functions (MF). The absence of a complete theoretical deflection prediction model of NSM-strengthened RC beams persuades this research to develop an Artificial Intelligence (AI) based prediction model using FLES. The proposed model uses triangular and trapezoidal MF to predict the deflection behavior of six NSM-strengthened RC beams. The research variables are strengthening materials and NSM bar length. In this study, two inputs (applied load and variable length) were used to predict two outputs (deflection of two types of strengthened RC beams). The relative error of predicted values was within 5% and the suitability of fit was close to 1.0 which affirms the efficacy of the FLES. Besides, a tiny difference was detected using triangular and trapezoidal MF for the prediction model.

Authors: Eddine Djessas Imed , Moussa Amrane , Salah Messast 
Published: January 2023

Abstract
The estimation of deformations after a large number of cycles is a major concern of geotechnical engineers. This paper presents an explicit formulation of the accumulated cyclic volumetric strain. This study is concerned with cyclic triaxial tests simulated through the calculation by the Finite Element Method. The parameters of identification of the first cycle (loading-unloading) are determined step by step, using, as a soil behavior model, the Soft Soil Hardening Model, then, the behavior of the soil after N cycles (N ---gt--- 1000) is simulated through the formulation proposed as a pseudo-creep. The comparison of the proposed method with several cyclic triaxial tests and a shallow foundation under cyclic loading approves the good compatibility of the proposed formula for this type of problem. This study does not take into account the effect of the grain size and the void ratio, things that can be translated by the coefficients C1 and C2.
Seismic Response of Concrete Gravity Dams Considering Hydrodynamic Effects
Authors: Linda Aouadj , Kadid Abdelkrim 
Published: January 2023

Abstract
This paper presents a dynamic analytical study to assess the effect of dam height as well as fluid compressibility on the gravity response of a concrete dam, considering the effects of hydrodynamic interaction. The analysis is carried out using the ADINA Finite Element software for empty and full reservoir conditions by considering several models. In the first model, the mass of fluid is taken into account by the concept of Westergaard added mass, in the second model; an acoustic fluid element is used to simulate the effect of water on the reservoir. The height of the dam is one of the main factors affecting the seismic response of gravity dams; because the change in height provides different responses depending on the natural periods, displacements and stresses obtained from static and dynamic analyses. The numerical results showed that the effect of interaction between the dam and the reservoir plays an important role in the precise estimation of the dynamic response of gravity dams. The hydrodynamic water pressure from the reservoir increases stresses in the dam body and horizontal displacements at the crest. The seismic response obtained by the incompressible water model (Westergaard) is compared with that of the compressible water model.
Effectiveness Assessment of Superplasticizer Admixtures: Case of Self-compacting Concrete Reinforced with Fine Mineral Fillers
Authors: Oualit Mehena , Irekti Amar , Hami Brahim 
Published: January 2023

Abstract
The use of superplasticizers in concrete production has become a common practice, especially when a high fluidity is required. On the other hand, the risk of segregation and the stability of these mixtures is ensured by the incorporation of a large volume of fine mineral additions. The present investigation is devoted to the study of the influence of three types of superplasticizers of different chemical compositions, namely: Combined Synthetic Polymers (CSP), Poly-Carboxylate Ether (PCE), and Modified Poly-Carboxylate Ether (MPCE) on the rheological behavior of self-compacting concrete (SCC) as well as on the mechanical properties at 3, 7, and 28 days of curing. Natural pozzolana (NP) and ground granulated blast furnace slag (GGBFS) were used as additions to stabilize the mixtures. The results revealed that the ether-based superplasticizer PCE gave the best workability and mechanical performance with low amounts (high efficiency). In addition, blast furnace slag promotes the obtaining of better properties whether in the fresh or hardened state compared to natural pozzolana.

Authors: Salih Omaima Ismaeel , Salman Muhammad Barjes 
Published: January 2023

This work tackles the use of the first group of the jussive articles (لم-lam, لما- lamma, لا الناهية- prohibition la, and لام الامر- imperative L prefix) in the Holy Quran and their realization in English by consulting the opinion of four translators.
Each Ayah is used to show the effect of a single article on the imperfect verb after it. This effect differs from one verb into another according to the type of this imperfect verb; The “Quiescence” (السكون) if the verb ends with a consonant, the elimination of the end vowel if the verb ends with a vowel and the elimination of N (حذف النون) if the verb is among the Arabic five verbs (الافعال الخمسة).
Each Ayah is analyzed in certain steps: the translation of four translators, the exeges of the certain Ayah, a grammatical analysis according to the opinion of the Arabic grammarians, and an analysis of the four translations adopted in relation to jussive.
