Background: History of pharmaceutical industry in Bosnia and Herzegovina (B&H) has its roots from 1951. Importance of domestic industry not just from economical aspect but also from public health perspective and as scientific base has not been evaluated previously. Objective: The aim of this article was to provide the review of the pharmaceutical industry developments in Bosnia and Herzegovina, its roots, current position and future perspectives.. Methods: Research of published scientific papers as well other documents and archives of pharmaceutical manufacturers has been conducted. We have also analysed market trends focusing on domestic producers. Results and Discussion: Over more than seventy years of B&H pharmaceutical industry has been developing. During Yugoslavia only two companies existed of which one, Bosnalijek is still present, while Sanofarm has been closed. After 1996, expansion of domestic manufacturers started and today six companies are present. They are mainly oriented to generic drugs production in different forms. Total market share of domestic producers in B&H is 20-25% which is relatively low comparing to other countries. Many of domestic manufacturers are exporting their products to some of the most demanding markets in Europe and Middle East. Conclusion: Long history of domestic drug manufacturers in B&H gives solid legacy for future developments. Importance of local producers has been confirmed during war in B&H and COVID-19 pandemic as a crisis situation, mainly from public health perspective and sustainable supply of essential medicines. Higher support by state and collaboration with academia in order to expand portfolio, especially in area of biologic medicines is required in future.

This paper analyzes the problem of DC cable selection in photovoltaic (PV) plants. PV plants can have tens of kilometres of one-way cables that are important parts of the system. The currents flowing through these cables can reach values of several hundred amps. Losses incurred on DC cables are up to 1%, which can be significant when measuring power loss during the operating period. Reduction of these losses can be achieved by increasing the cross-section of the cable. The paper describes the requirements set by the standards for selecting cable cross-sections. An analytical criterion function that connects electricity losses and cable crosssection were deduced. This function depends on several parameters such as electricity price, cable price, the average number of sunny hours per year, average amount of electricity through cable, interest rate, loan repayment period, and plant operation period. Several cases with the analysis of the obtained results are presented.

INTRODUCTION MATERIALS AND METHODS

The designing process of an IoT (Internet of Things) network requires adequate knowledge of various communication technologies that make the connection of the IoT modules possible. Many important factors such as scalability, bandwidth, data rate (speed), coverage, power consumption, and security support need to be considered to answer the needs of an IoT application with regards to the implemented radio communication technology. This paper studies the choices of three major LPWAN (Low-Power Wide-Area Networks) technologies that are currently leading in the market of radio communication technologies. Focusing on Sigfox, LoRaWAN (Low-Range Wide-Area Networks), and NB-IoT (Narrow-Band Internet of Things), this work intends to give the respective pros and cons of the mentioned technologies and a clear view of the recent trends and effective choices of radio communication technologies for major smart IoT applications.

Thoroughly validated instruments can provide a more accurate and reliable picture of how the instrument works and of the level of health literacy in people with type 2 diabetes mellitus (T2DM). The present work aimed at cross-cultural adaptation and validation of the Functional, Communicative and Critical Health Literacy Instrument (FCCHL) in patients with T2DM in Serbia. After translation and back-translation, views from an expert group, one cognitive interview study (n = 10) and one survey study (n = 130) were conducted among samples of diabetic patients. Item analysis, internal consistency, content validity, confirmatory factor analysis (CFA) and reliability testing were performed. When all 14 items were analyzed, loading factors were above 0.55, but without adequate model fit. After removing two items with the lowest loadings FHL1 and IHL2 the fit indexes indicated a reasonable normed χ2 (SB scaled χ2/df = 1.90). CFI was 0.916 with SRMR = 0.0676 and RMSEA = 0.0831. To determine internal consistency, Cronbach’s alpha coefficient was 0.796 for the whole FCCHL-SR12. With only minor modifications compared to the English version, the 12-item FCCHL instrument is valid and reliable and can be used to measure health literacy among Serbian diabetic patients. However, future research on a larger population in Serbia is necessary for measuring the levels of HL and their relationship with other determinants in this country.

Quantum many-core processors are envisioned as the ultimate solution for the scalability of quantum computers. Based upon Noisy Intermediate-Scale Quantum (NISQ) chips interconnected in a sort of quantum intranet, they enable large algorithms to be executed on current and close future technology. In order to optimize such architectures, it is crucial to develop tools that allow specific design space explorations. To this aim, in this paper we present a technique to perform a spatio-temporal characterization of quantum circuits running in multi-chip quantum computers. Specifically, we focus on the analysis of the qubit traffic resulting from operations that involve qubits residing in different cores, and hence quantum communication across chips, while also giving importance to the amount of intra-core operations that occur in between those communications. Using specific multi-core performance metrics and a complete set of benchmarks, our analysis showcases the opportunities that the proposed approach may provide to guide the design of multi-core quantum computers and their interconnects.

Introduction: Musculoskeletal disorders (MSDs) imply damage to muscular or skeletal systems, which usually develop due to strenuous, repetitive activity, or an inflammation process. The therapy with capacitive and resistive electronic transfer (CRet) and high-intensity laser therapy (HILT) have mainly been applied for pain relief in these conditions. This paper aims to provide an overview of the efficient results of CRet therapy and HILT in managing pain associated with musculoskeletal disorders found in the available literature. Methods: Articles related to musculoskeletal disorders were searched through electronic databases, such as PubMed, Web of Knowledge, Lilacs, Cochrane, Research Gate, and available website search tools. After excluding records that are not clinical trials and studies (such as review articles, patient information, and Ph.D. papers) and articles which did not deal with pain in musculoskeletal disorders, 61 articles met our criteria and were included in the overview. Results: By reviewing the selected articles related to CRet therapy and HILT effects on pain in musculoskeletal disorders, it was found that both therapies have a favorable effect on pain reduction. Conclusion: The selected papers showed that both therapies are powerful tools for pain reduction. Although there are no specific protocols, including the number and frequency of therapies applied and other parameters, in both therapy modalities, pain alleviation occurs during or immediately after a therapy cycle application.

Introduction: Bilateral ectopic pregnancy is a very rare condition which occurs in 1/725 - 1/1580 ectopic pregnancies, most commonly after induced assisted reproductive techniques. Aim: To present the case of spontaneous bilateral tubal pregnancy, and the problem of insufficiency of available diagnostic methods, which causes that an accurate diagnosis can mostly be made intraoperatively. Case Report: A 37-year-old female, nulliparous, comes at the Clinic of Gynecology and Obstetrics of CCUS, complains of intense suprapubic pain, and difficulty urinating. The expected menstruation was absent for more than 2 weeks. The Grav index test was positive. Beta hCG values were 6312 IU/L. On examination, the patient was extremely pale, hypotensive, gave the impression of hemorrhagic shock, and the abdomen was diffusely palpably painful. After emergency TV ultrasound, then ultrasound and CT of the abdomen and small pelvis, which indicate a moderate amount of thicker fluid in the abdomen and small pelvis in terms of hemoperitoneum and with the left contour of the uterus an oval zone most likely to correspond to ectopic pregnancy, an indication for emergency surgery was made. A laparotomy was performed, and partly liquid and partly coagulated blood was found in the abdomen. The left tube in the isthmic part was ruptured with active bleeding. Right Fallopian tube was pathologically changed, livid, with visible suspicious pregnancy in the ampullary part. Bilateral salpingectomy was performed, and samples are sent for PHD analysis that shows the presence of chorionic villi in both tubes. Conclusion: When ectopic pregnancy is suspected, the possibility of bilateral tubal pregnancy should always be kept in mind, especially in cases accompanied by acute pelvic pain with signs of hemorrhagic shock

In this article we consider the applicability of distance education on the elementary level from parents’ perspectives and present the limitations stemming from the degree of support that students in elementary education need from their parents. The dilemmas regarding the possible levels of students’ development of independence and self-orientation, and the parents’ roles are highlighted. We believe that due to these limitations, distance learning has some of the characteristics of home-schooling. The subject of the research in the empirical part of this study focused on parents’ attitudes. Parental attitudes, based on a previously established multi-factor model, become clear from the parents’ experiences (Kolak, Markić & Horvat, 2020) where factors regarding the demands of teaching and the competence of parents as substitute teachers, were separated. Parents’ characteristics (e.g., gender, age, educational status and involvement) were found to influence their attitudes. The results of the research indicate the importance of parents in distance learning during the pandemic which adds a new and more significant role in the educational process of their children.

Due to their remarkable magnetic properties, such as a high maximum energy product, high remanence, and high coercivity, NdFeB magnets are used in a variety of technological applications. Because of their very limited recycling, high numbers of spent NdFeB magnets are widely available in the market. In addition to China’s monopoly on the supply of most rare earth elements, there is a need for the recovery of these critical metals, as their high import price poses an economic and environmental challenge for manufacturers. This paper proposes a pyrometallurgical recycling method for end-of-life NdFeB magnets by oxidizing them in air as first required step. The main goal of this method is to oxidize rare earth elements from NdFeB magnets in order to prepare them for the carbothermic reduction. The experimental conditions, such as the oxidation temperature and time, were studied in order to establish the phase transformation during oxidation using the Factsage Database and experimental conditions. Our thermogravimetric analysis TGA analysis revealed an increased sample mass by 35% between room temperature and 1100 °C, which is very close to the total calculated theoretical value of oxygen (36.8% for all elements, and only 3.6% for rare earth elements REE), confirming the complete oxidation of the material. The obtained quantitative analysis of the oxidation product, in (%), demonstrated values of 53.41 Fe2O3, 10.37 Fe3O4; 16.45 NdFeO3; 0.45 Nd2O3, 1.28 Dy2O3, 1.07 Pr2O3, and 5.22 α-Fe.
