In the process of creating composites, especially if we talk about wood-based composites, great attention should be paid on a variety of factors which affect the final composite properties.One of the essential elements is proper adhesive selection. Most common used are synthetic formaldehyde adhesives. We are aware how dangerous emission of free formaldehyde can be; we tend to minimize its usage. Using adhesives which are safe for the environment and humans as well, we tend to find safer composites which are ecologically acceptable and recognized as a better option.The paper briefly describes the adhesives used so far and their dangers, and selects several types of adhesives with basic characteristics that can meet the requirements for the production of ecologically acceptable composite panels, with an emphasis on wood-based composites. Certain tests and achievements in the development of these adhesives are also presented.

Abstract Introduction: Bones, lungs, brain and liver are the most common metastatic sites of breast carcinoma, although invasive lobular carcinoma can give metastases to less common sites, such as the gastrointestinal tract and the female genital tract. Case presentation: We present the case of a 57-year-old female with colic abdominal pain that was sent to surgery for cholecystectomy. Histopathology revealed a poorly cohesive individual or in single file neoplastic cells infiltrating all layers of the gallbladder. Immunohistochemistry revealed these cells to be CK 116, CK7, GCDFP-15, ER and PR positive, and CK20, HER-2, S-100 and E-cadherin negative. PET/CT showed numerous lytic bone lesions, but ultrasound, mammography, MRI and PET/CT revealed no breast mass. Conclusion: Although rare and poorly understood, metastases of invasive lobular carcinoma to gallbladder do exist in a minor percentage of patients, presenting usually as exacerbated cholecystitis. The problem are silent cases and patients with no history of breast carcinoma. This case is unique in that even after the diagnosis of metastatic lobular breast carcinoma to the gallbladder, the primary tumour of the breast was not detected.

Abstract Objective of this study was to identify the histopathological patterns and their frequency in testicular biopsy specimens from azoospermic patients and to categorize it according to Modified Johnsen scoring system. Methods: Testicular biopsies from male patients with clinical diagnosis of azoospermia were included in this study. All tissue samples were fixed in buffered 10% formalin, routinely processed and stained with Hematoxylin and Eosin. All cases were examined microscopically and categorized according to the histopathological patterns and Modified Johnsen scoring system. Results: Total 219 cases of testicular biopsies from 125 azoospermic male patients were evaluated, with 94 cases of bilateral testicular biopsy. The most prevalent age group was of 30-39 years (66.2%). The most common histological pattern was of Sertoli cell only syndrome (58.4%) while the least represented pattern was germ cell maturation arrest, seen in 4.6% cases. The most common Modified Johnsen score was 2 (66.7%). There was discordance in histologic pattern in both testes in 12.76% of patients who had bilateral testicular biopsy. Conclusion: Our study gives an insight on the most common histopathological patterns of azoospermic patients and emphasizes the need for a better national statistics and epidemiological studies of this entity. It also points out the significance of the bilateral testicular biopsy, as both, diagnostic and therapeutic procedure.

Preschool wheezing and childhood asthma create a heavy disease burden which is only exacerbated by the complexity of the conditions. Preschool wheezing exhibits both “curricular” and “aetiological” heterogeneity: that is, heterogeneity across patients both in the time‐course of its development and in its underpinning pathological mechanisms. Since these are not fully understood, but clinical presentations across patients may nonetheless be similar, current diagnostic labels are imprecise—not mapping cleanly onto underlying disease mechanisms—and prognoses uncertain. These uncertainties also make a identifying new targets for therapeutic intervention difficult. In the past few decades, carefully designed birth cohort studies have collected “big data” on a large scale, incorporating not only a wealth of longitudinal clinical data, but also detailed information from modalities as varied as imaging, multiomics, and blood biomarkers. The profusion of big data has seen the proliferation of what we term “modern data approaches” (MDAs)—grouping together machine learning, artificial intelligence, and data science—to make sense and make use of this data. In this review, we survey applications of MDAs (with an emphasis on machine learning) in childhood wheeze and asthma, highlighting the extent of their successes in providing tools for prognosis, unpicking the curricular heterogeneity of these conditions, clarifying the limitations of current diagnostic criteria, and indicating directions of research for uncovering the etiology of the diseases underlying these conditions. Specifically, we focus on the trajectories of childhood wheeze phenotypes. Further, we provide an explainer of the nature and potential use of MDAs and emphasize the scope of what we can hope to achieve with them.

Modeling flow in open channels is essential for determining channel capacity and predicting flood events. The key segment for creating flood hazard and risk maps is a high-quality hydraulic model of the flow in the main bed with its tributaries. Several software packages have been developed for hydrodynamic simulations of flood events. In addition to the geometric characteristics of the watercourse, the equations of a one-dimensional flow model include a parameter that connects all influences that provide resistance to the flow of water. Determining the roughness of a natural channel is one of the most demanding procedures for the development of hydraulic models. Therefore, it is necessary to calibrate and validate the Manning coefficients of the channel roughness using simulation models. In the present study, the estimation of channel and floodplain roughness for the Veseočica River in Bosnia and Herzegovina was performed using the HEC-RAS hydrodynamic model. After calibration and verification of the model, flood hazard maps were created for flood waves with return periods of 20, 100, and 500 years. ArcGIS and HEC-GeoRAS software tools were used to create the flood risk maps.

This paper brings the introduction of the analysis of foundation solution for the noise protection walls on the reinforced earth along the Highway Corridor Vc, a road and rail transport corridor that connects Hungary, Croatia and Bosnia and Herzegovina, included in the network of Pan-European transport corridors. A solution with pile foundations made of steel IPE profiles is presented in detail. During the design and modelling, as well as the calculation of the structural foundation, the modern software program PLAXIS was used, and the calculation was made in accordance with EN 1997 Eurocode 7, Geotechnical Design. Special attention is devoted to the analysis of the impact of driving IPE steel profiles, as foundation piles, on reinforced earth. The presented solution was then verified by an additional control calculation and a field test of the impact of the horizontal load on the bearing capacity of the IPE steel profile driven into the reinforced slope. Based on the conducted analyses and testing, it has been proven that it is possible to build noise protection walls on the reinforced earth without disturbing the internal stability and functionality of the reinforced earth.

In order to determine the bending strength of wood or wood-based panels, an experimental method is typically used to test samples of different sizes that involves bending or compression. However, such tests are expensive and time-consuming, so mathematical models are often applied that allow predicting the bending strength based on a smaller number of obtained test results. One such model is the Lagrange interpolation polynomial. The study discusses Lagrange’s interpolation model. Using the results of tests done on plywood of various thicknesses, approximates the bending strength of plywood for values that could not be tested directly and provides an estimate of strength for particular values.

Educational institutions record an increase in behavioral disorders in children and adolescents every day, with severe symptoms that result in hospitalization or the imposition of criminal sanctions for juvenile delinquents. Behavioral disorders of children and young people stand out as one of the primary problems of today's society. The purpose of this paper is to give a detailed insight into the state of emotional and behavioral disorders, from those that are hidden such as withdrawal, apprehension, fear,anxiety to behavior that children and young people come into conflict with others, even committing acts that are legally recordable as punishable. It has been proven in various studies that early diagnosis and preventive interventions in working with children give the best results. The hypothesis that behavioral disorders and emotional problems among children and young people in primary and secondary schools are present and require the application of appropriate preventive and treatment programs has been confirmed. Through the presentation of modern approaches to the detection, prevention and diagnosis of behavioral problems, this work shows the relationship between biological factors, parental qualities, education, the influence of peers, school and socialnorms, and the way in which they become risky for the development of problematic behavior. Detecting risk factors and stopping the action of risk processes, which have been proven to have a positive correlation with the occurrence of aggressive behavior in children, leads to a decrease in the rate of its occurrence. It has been observed that there are several successful ways of working with children that result in a reduction in the rate of behavioral disorders, even in provoking situations. Communication and problem-solving skills training can successfully reduce inappropriate child behaviors. Teaching social-emotional skills, in addition to reducing behavioral disorders, also results in higher self-esteem and more positive attitudes in children.Schoolshave a need for continuous implementation of science-based prevention programs that include interventions aimed at children and work with parents Keywords: Behavioral disorders, interventions, children, adolescents, parents, prevention programs

The work represents the continuation of the research of the maximum bending stress force of a wooden beam up to the moment of failure, which is defined experimentally and with a corresponding mathematical model. The goal was to confirm the accuracy of the mathematical model of the breaking force using numerical simulation and the Solid Works software. Five different types of wood and five different beam thicknesses were used as input parameters whose influence was monitored trough the simulation. The stress deformation state and deflection for the calculated fracture forces were analysed separately for each variant. The breaking force model, which is defined depending on the density of the wood and the thickness of the board, proved to be adequate for defining the maximum stresses and deflections when bending beams.

Large-scale incorporation of new energy generation units based on renewable sources, such as wind and photovoltaic power, drastically alters the structure of the power system. Because of the intermittent nature of these sources, switching in grids (connection and disconnection) occurs much more frequently than with conventional sources. As a result, the power system will inevitably experience a large number of transients, which raises questions about the stability of the system and the quality of the electrical energy. Therefore, measuring various types of transients in power system is crucial for stability, power quality, fault analysis, protection design, and insulation design. Transient recorders that are currently used are generally expensive and only suitable for particular locations in power systems. The number of installed transient recorders is insufficient for a comprehensive analysis of problems that may occur. Hence, it is important to have inexpensive and efficient transient recorders that can be installed at multiple points in the power system on various types of objects. It is also essential to have a transient record database with open access, which can be used by researchers to develop new analysis techniques based on artificial intelligence. This paper proposes an inexpensive measurement and acquisition system designed to record transient phenomena on different objects within the power system. The system is designed to use autonomous power, a standardized data acquisition module, a low-budget system for transmitting recorded transient events to the server via mobile network, and a sensor system adapted to the object where transients are recorded. The proposed system is designed to be used for all types of objects in the power system where transients may occur, such as power lines, transmission towers, surge arresters, and transformers. All components of the system are described, and the system is tested under laboratory conditions. The modular nature of the system allows customization to the specifics of the location in power system by choosing appropriate components. The calibration method of the custom designed Rogowski coil is described. The cost analysis of the proposed system and power consumption analysis are performed. The results show that the system’s performance meets application requirements at a low cost.

The objective of this research was to investigate impulsivity among children with dyslexia and comorbid dyslexia/ADHD. Children with these disorders, along with a non-ADHD/dyslexia sample, completed a self-report on impulsivity. Additionally, a specific impulsivity scale was completed by the children's parents and teachers. The analysis revealed a main effect for groups, indicating that children with dyslexia and comorbid dyslexia/ADHD reported more symptoms of impulsivity than normally achieving children. Furthermore, differences were identified between children with dyslexia and those in the comorbid dyslexia/ADHD group. Specifically, children with comorbid dyslexia/ADHD exhibited more impulsive behavior than children with dyslexia alone. Notably, there was a high level of consensus in ratingsof impulsivity between children and their teachers and parents.Keywords:dyslexia, ADHD, impulsivity

Abstract Islanded microgrids with low-inertia distributed energy resources (DERs) are prone to frequency fluctuations. With the increasing integration of DERs in microgrids, the complexity of control and stability has also increased. Moreover, the integration of DERs into microgrids may result in a power imbalance between energy supply and demand during sudden changes in load or energy generation. This can cause frequency variations in the microgrid, which could have disastrous consequences such as equipment damage or even blackouts. This paper proposes a control strategy to ensure the efficient operation of an islanded hybrid microgrid consisting of a PV generator, battery energy storage system (BESS), and emergency diesel generator. According to Energy Exchange Model proposed in this paper, the hybrid system presented operates independently without being connected to the electrical grid, where the PV system and BESS act as the main energy sources, while the emergency diesel generator provides active power backup with voltage and frequency regulation. The novel in this paper is also that DER aids in frequency regulation during active power transients by delivering and absorbing active power in accordance with the inverter's suggested P droop control strategy. In this way inverter droop control decreases system frequency nadir emulating so called “synthetic inertia”. To design both the islanded hybrid system and the proposed control strategy, the MATLAB/Simulink environment is utilized. Based on the results, it can be concluded that the analyzed microgrid system is capable of maintaining stability and operating efficiently in a range of operating conditions.

The focus of the authors’ interest is the criminal offense of embezzlement in the service, which we classify in the catalogue of corrupt criminal offences, by its nature, operationalization method, consequences and other specificities. In addition, it is a criminal offense from the catalogue of premeditated criminal offenses, so the paper pays due attention to the interconnection and cumulative conditionality of objective and subjective elements, that is, the action of execution and the subjective component. Special attention is directed to the discovery of the existence of this criminal offense, i.e. the realistic discovery possibilities and capacities, then the objectivesubjective concept based on the legal description of this criminal offense, and the aspect of gathering the necessary evidence in connection with establishing the existence of the criminal offense and guilt, considering the restrictive legal requirements. The complexity of discovering and proving this criminal offense arises from the very nature of this criminal offense and certain specificities that are directly related to the way it is operationalized. The criminal law autonomy and independence, as well as the clear differentiation of this criminal offense in relation to other related criminal offences, are emphasized in order to avoid (possible) wrong identifications, and with the aim of a better and more comprehensive understanding of the very nature of this criminal offence

Abstract Voltage unbalance is common issue encountered in low voltage distribution networks, caused by uneven allocation of single-phase customers among phases. This paper analyses part of real low voltage distribution network in Bosnia and Herzegovina. The impact of single-phase customers and single-phase connected micro photovoltaic power plants (MPPP-s) were analysed. To reduce unbalance and improve voltage profiles, Phase Balance Optimization toolbox in DIgSILENT PowerFactory software was performed in six scenarios with different distribution of customers and different percentage of penetration of MPPS-s. The aim was to find method with least number of changes in customer and photovoltaic phase connection that fits within defined limits of voltage variations and voltage unbalance of European standard for power quality (EN 50160). Conclusion is that MPPP-s cause voltage increases in the network, as well as an increase in voltage unbalance, but these effects can be mitigated by proper distribution of customer loads and MPPS-s among phases.
