The study presented in this paper explored the relationship between corporate entrepreneurship and business model innovation of companies in Bosnia and Herzegovina (B&H) after the COVID-19 pandemic. In particular, the authors aimed to analyze how the individual dimensions of corporate entrepreneurship influence business model innovation by using the dynamic capabilities view. The study empirically analysed a sample of 100 companies using regression analysis. The findings revealed that each dimension of corporate entrepreneurship positively and significantly impacts business model innovation. Innovativeness, proactiveness, risk-taking, autonomy, and competitive aggressiveness positively affected the innovation of the business model. The results of this study confirm that entrepreneurial initiative is a good predictor of a company’s ability to innovate business models. The implication for management is to deepen the understanding of how corporate entrepreneurship promotes and shapes an innovative business model. This increases companies’ success and overall well-being in B&H after the COVID-19 pandemic.

The Internet of Things (IoT) is one of the key technologies for the digital transformation of both business and society. The paper primarily aims to investigate the structure and dynamics of academic publications in English dealing with issues of IoT development – from a marketing perspective, using methods of systematic mapping, i.e., co-citation analysis, bibliographic coupling, and analysis of the co-occurrence of keywords in the Scopus and Web of Science (WoS) databases. Analysis of research papers enables the identification of the most influential articles, papers, and journals, as well as visualization of the keywords and co-authorship co-occurrences. There has been an exponential increase in studies on IoT applications in marketing, indexed in Scopus and WoS citation databases. An insight into analyzed papers shows that companies utilize large amounts of data generated by the IoT to gain insights into customers’ supply and value creation, which helps strengthen their relationships with customers and pursue more efficient marketing policies and practices, ultimately leading to a competitive advantage. The IoT is expected to evolve into a vast network that includes smart devices and significantly influences people’s behavior, especially decision-making at different stages of the purchasing process.

: The aim of this study is to examine the effect of plant fat sources in sheep feed on somatic cells and the total number of microorganisms in raw milk samples obtained from 210 sheep, breed Pramenka in Una-Sana Canton. The research was conducted in three periods: winter, spring and summer. The herd was divided into experimental and control groups of sheep. In the experimental groups of sheep in each period of the study, omega-3 supplements were added to the diet, namely extruded flaxseed in the amount of 3.5%. The influence of added omega-3 supplements on the microbiological parameters of raw sheep milk, which was milked from experimental and control groups of sheep every fifteen days of the experiment in all periods of the study, was examined. Analysis of variance (ANOVA) found that during the winter and summer feeding period there is a statistically very significant influence of both experimental factors (treatment and period) on the total number of microorganisms and somatic cells in raw sheep milk (p <0.001). In the spring diet in somatic cells, factor treatment did not show a statistically significant effect (ns).

: Ultrasonic flowmeter works on the principle of transmitting and returning ultrasonic waves that pass through the liquid, ie. fluid, and is used to measure the speed of fluid movement through a pipeline or some other structural form of fluid movement. By knowing the velocity of the fluid and the cross-sectional area of the pipeline or other system, the value of the volumetric or mass flow can be obtained indirectly. Fluid flow measuring device model OMNI TDI 200H owned by the laboratory of the Biotechnical Faculty was used for the first time to measure the flow of purified water at the outlet of the plant device of the training center "Grmeč", built as a pilot plant. The paper will describe the role and importance of flow measurement by the conventional method and present the results of the trial operation of an ultrasonic flow meter, model OMNI TDI 200H.

Legionella bacteria are microorganisms found in water and moist soil. They are especially favoured by moisture and heat, especially in different types of swimming pools where these bacteria reproduce and survive even for several months. Legionella spp. cause human diseases if they are introduced into the body through the respiratory tract. This most often happens by inhalation of aerosols, and less often by microaspiration of water contaminated with Legionella . The research aims to examine the presence of Legionella spp. bacteria in pool waters and the factors that influence their maintenance in these waters. Water samples were taken from 13 swimming pools that were registered for swimming and recreation in the Central Bosnian Canton in 2022. The presence of legionella was tested, and temperature, pH values (method BAS EN ISO 10523:2013), and residual chlorine concentrations were measured. The temperature was measured by immersing the probe with a calibrated thermometer until the stabilization of temperature values on the display was reached. The free residual chlorine was measured by the standard colourimetric technique – the N, N-diethyl-phenylenediamine method (HANNA Instruments 96701, Rhode Island, USA). Descriptive statistics and the Chi-square test will be used for data analysis. Statistical analysis of the obtained data will be performed using the basic functions of MS Excel and GraphPad Prism. Of the total number of analyzed samples (n = 13), the presence of legionella was confrmed in 4 samples (31 %). The average water temperature of the samples taken

• Based on the previous study of the heat-treated wood at 0-3 mm surface layer, this study focuses on the transition of thermal modification intensity on 160-220 °C heat-treated poplar from surface to core layers. The color change was evaluated by CIELAB, and surface hardness was detected via Shore D (HD) and pressing ball method (H R ); furthermore, the FT-IR was applied to detect the thermal degradation of wood components. The results show that the degradation of cell wall components in the surface layer of heat-treated poplar wood is greater than that in the core layers

A 2-year study was done to compare fruit morphological and chemical composition of three nectarine cultivars grown in south Hercegovinia conditions. A high variability among and within cultivars was found and significant differences were observed among them in all properties analyzed. On the basis of evaluated data, the best fruit performance was registered in ‘Caldesi 2000’ and ‘Venus’ grown in the condition of this part of the Mediteran. This evaluation may help to select a set of nectarine cultivars with better fruit quality attributes, which in our growing conditions might be indicated in ‘Caldesi 2000’ and somewhat in ‘Venus’. The highest average of fruit width (61.18 mm) and fruit weight (148.24 g) was found in cultivar Caldesi 2000. As for friut thickness, also cultivar Caldesi 2000 had the highest value (55.39 mm). The results for the highest fruit length (60.48 mm) had Venus cultivar also fruit stone weight length, width and thickness. The contents sugars (glucose, fructose) total soluble dry matter, and total acids in fruits were found in cultivar Venus, but pH and sucrose were found in cultivar Sun Grand.
