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.

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.

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.

Museum development is a side effect of tourism development since museums are significant components of cultural and tourist infrastructure, and tourism encourages infrastructure development in general. In Bosnia and Herzegovina, where tourism is a critical sector of the economy with a decades-long flow, the pattern of comparative development of tourism and museums has been recognized. The study provides a comparative review of the country's tourism and museum development, showcasing the multiple benefits of tourism and museums. Museums are one of the most important socio-cultural benefits of tourism because they preserve and present heritage, improve science, education, and cultural profiling, encourage employment and visitation, provide a better stay, generate income, and contribute to environmental urbanization and higher living standards. The identification of museums and museum resources revealed that, during the past three decades, approximately thirty museums of a predominantly thematic character have been established, particularly in the country's most visited destination (Sarajevo). Furthermore, an open-air museum (ethno-village) trend has begun. Museum visitation is increasing in tandem with tourist trips to the country, despite a lack of adequate monitoring (incomplete figures that are inconsistent with the situation in the field). Despite the fact that the global crisis disrupted tourism and museum development (COVID-19), both areas are key drivers of economic revitalization, as evidenced by new ideas and projects in this field. However, in addition to the benefits of increased museum activity, the study highlighted certain issues (e.g., lower engagement of professional staff and women etc.), which will encourage future research to provide more sustainable strategies for museum development.

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

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 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.

Abstract This paper presents a method for distributed generation (DG) allocation in medium voltage (MV) distribution system based on energy loss minimization. The main objective of the research is to design, implement and test a DG allocation (siting and sizing) method and to investigate how optimal DG allocation influence the operational parameters of the system from the Distribution System Operator (DSO) perspective. The problem is formulated as a single objective optimization problem solved by using both genetic algorithm and particle swarm optimization techniques. Model of a realistic Electric Power Distribution System (EPDS) and IEEE 37-bus EPDS are used as test systems. The results confirm that proposed algorithms can be used for practical DG allocation. The research presented contributes to the field as it provides a DG allocation method for energy loss reduction performed on a EPDS which can be applied in realistic planning and regulatory situations using open-source software.

Aimof this study was to present data on addicts with the imposed protective measure of compulsory treatment of addition that were sent to the Institute for Addiction Diseases for the period 2014-2020. The study compares artsof law violation, art of addiction as well as duration of the protective measure of compulsory treatment.Out of 61 patients, 59 (96 %) were males and 2 (4%) females. The only reason for compulsory treatment for all of them was domestic violence. Out of 61 patients 41 (67%) underwent compulsory treatment due to use of psycho-active compounds (PAS) and 20 (33%) due to use of alcohol. Incidence of alcohol or PAS was statistically significant higher in males than in females (19 vs 1, p<0.001; 40 vs 1, p<0.001, respectively). Duration of the treatment was significantly longer in patients who used PAS than in those who used alcohol (10.29 vs 7.4 months; p<0.05). There was not statistically difference between duration ofthe treatment in males and females (9.36 vs 9.00 months; p>0.05). Incidence of the compulsory measures was significantly higher in 2018, 2019 and 2020 than in 2014, 2015 and 2016 (p<0.001). In all analyzed years, except 2015, incidence of the mandatory measureswas significantly higher in patients who misused PAS than who misused alcohol. The most common difficulties are:lowmotivational capacity,inadequate way of thinking, inadequateway of behaving with the adoption of new models and, ultimately, inadequate independent functioning. Keywords: addiction, compulsory treatment, violation of the law, criminal behaviour.

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.

Timber structures have been a popular choice for construction due to their natural and aesthetic appeal. However, with the increasing focus on sustainability and eco-friendliness, alternative building materials are gaining popularity. One such material that has gained attention is coconut wood. Coconut wood is a by-product of the coconut industry and has several unique properties that make it an excellent choice for timber structures. This paper reviews the properties and applications of coconut wood in timber structures and discusses its advantages, limitations, and challenges. We discussed the physical and chemical properties and durability of coconut wood. The average density of coconut palm wood ranges from 0.41-1.11g/cm3, while its moisture content ranges from 50% to 400%. Coconut wood has low shrinkage and swelling rates, reducing the risk of cracking or warping. The holocellulose content is about 67% while the lignin content is approximately 25%. Chemical and natural products, are effective in protecting coconut wood against decay and insect attack. Understanding such characteristics of coconut wood is critical for its optimal utilization in various industries. By employing appropriate preservation techniques and utilizing this versatile and sustainable resource, coconut wood can continue to provide significant benefits for communities and industries around the world.

The aim of this study was to investigate the mechanical behavior of beech and fir finger joints under laboratory conditions.
