    Sensor Network Information Flow Control Method with Static Coordinator Within Internet of Things in Smart House Environment
    (Elsevier, 2017) Jurenoks, Aleksejs; Jokić, Dejan
    Nowadays the technical solutions related to energy resource management are being rapidly developed and integrated into the daily lives of people. The energy resource management systems use sensor networks for receiving and processing information during the realia time. Despite the large number of research related to increasing the life expectancy of a network, node positioning, network clustering as well as the optimization of the data-processing model, issues related to the data flow management and classification of the information become more and more topical; they allow to reduce the amount of transmitted information within the network. The network load of the unstructured information flow is the most important aspect that impacts the service quality of the network as well as the life expectancy of a node; as a result, the methods of network performance optimization and increase in life expectancy in the networks with a high information transmission rate become ineffective. Nowadays the amount of transmitted information in the Internet of Things networks is increased and becomes chaotic which results in the reduction of the overall network efficiency and life expectancy. The article discusses the management method of the network data flow that can respond to a data flow programming task whilst taking into account the balancing of the node energy in the network

    Analysis of myofibrillar and sarcoplasmic proteins in pork meat by capillary gel electrophoresis
    (Kemerevo State University, Russia, 2018) Grujić, Radoslav; Savanović, Danica
    Myofibrillar and sarcoplasmic proteins were extracted from pork meat (M. Longissimus dorsi) and then separated by capillary gel electrophoresis (CGE). Migration time and peak areas of individual protein molecules in the electropherogram were analysed. The electropherograms obtained after the separation of myofibrillar proteins contained 53 well-separated peaks, of which the following were identified: thymosin, myosin light chain-3 (MLC-3), myosin light chain-2 (MLC-2), troponin C, troponin I, myosin light chain-1 (MLC-1), tropomyosin 1, tropomyosin 2, troponin T, actin, desmin, troponin, C protein, and myosin heavy chain (MHC). The relative concentration of the identified myofibrillar proteins was 74.5%. Of the 56 separated sarcoplasmic proteins the following were identified: myoglobin, myokinase, triosephosphate isomerase, phosphoglycerate mutase, lactate dehydrogenase, glyceraldehyde phosphate dehydrogenase, aldolase, creatine kinase, enolase, phosphoglucose isomerase, pyruvate kinase, phosphoglucomutase, and phosphorylase b. The relative concentration of the identified sarcoplasmic proteins was 83.6% of all sarcoplasmic proteins extracted from the pork meat.

    Exploring Wineries andWine Tourism Potential in the Republic of Srpska, an Emerging Wine Region of Bosnia and Herzegovina
    (MDPI, 2022) Vukojević, Dajana; Tomić, Nemanja; Marković, Nenad; Mašić, Branislav; Banjanin, Tijana; Bodiroga, Radomir; Đorđević, Tijana; Marjanović, Miloš
    The aim of this paper is to present the current state and wine tourism potential in the Republic of Srpska with the primary focus on its wineries and their activities towards attracting wine tourists from all over the world. To achieve this, a survey was conducted among 37 wineries in the Republic of Srpska. The first part of the questionnaire included data about planted grape varieties, annual yield, wine production, vineyards areas, and winery staff information. The second part of the survey was dedicated to the degree of participation of wineries in wine tourism activities and the services offered to wine tourists. Results indicate that the major factors thwarting further wine tourism development are the lack of accommodation and catering facilities as well as tours in foreign languages. One of the problems is the current lack of wine routes generally seen as critical supporting tools for wine tourism development. Based on the research results, the authors propose two wine routes in the Republic of Srpska, the Northern and Southern wine routes. Further wine tourism development should be focused mainly on these areas.
