Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state method defined by ISO 13790. In the Republic of Serbia, most of families live in single-family houses built before the energy certification of buildings was introduced. Therefore, the estimation of energy performance of the existing buildings is important for labeling, and evaluation of energy saving measures and energy strategies to be implemented. This paper examines the applicability of monthly method defined by National legislation on the existing buildings stock in Serbia, by comparing it to the more accurate dynamic simulation method. Typical single-family houses are taken as a test case, since they are responsible for about 76% of energy consumption for heating. The results show that the dynamic simulation method estimates 21% to 54% higher energy need for heating, compared to the monthly method. Also, the monthly method estimates up to 13% higher savings by typical building envelope energy saving measures, compared to the dynamic simulation. This paper recommends improvement in procedures for calculation of building energy performance index to better assess energy consumption, effects of energy saving measures, and create solid background for developing and implementing of energy saving strategies.

The aim of this paper is to propose the intermodal logistics Corridor Vc, relying on the European Union transport policy, which will be in the function of regional development. The main goal is to analyze a potential route of freight intermodal transport between the ports of Ploče and Brčko in order to popularize this intermodal line at the international level. Among the most important activities in achieving this goal is the integration in the Euro corridor system. This integration is of crucial importance for companies to successfully execute their supply chain processes both domestically and internationally. The paper is based on the analysis of the current socio-economic situation and the condition of the intermodal transport system in Bosnia and Herzegovina (BiH), as well as existing strategic studies and development plans. This paper sheds a light on the creation of a strong integrated intermodal freight transport network in BiH, that will be a quality alternative to other international intermodal flows from the aspect of shorter transport time, lower transport costs and more favorable ecological aspects of transportation.

Background: Ventilator-associated pneumonia (VAP) is one of the most common hospital-acquired infections in patients hospitalized in intensive care unit (ICU). The aims of this study were to evaluate quantitative culture of bronchoalveolar lavage (BAL) in the diagnosis of VAP comparing with clinical pulmonary infection score (CPIS), and to determine positive and negative predictive values of the test. Methods: A total of 209 samples were taken from the patients hospitalized in ICU with clinical suspicion on VAP, along with the CPIS. As the cut-off value of test, quantity of 104 colony-forming unit (CFU)/mL was taken, according to Centers for Disease Control and Prevention (CDC) recommendations. Results: Positive culture has been found in 142 patients (68%). The most common isolates were Acinetobacter baumanii in 49 (34.5%) patients, Klebisella pneumoniae in 31 (21.8%), Pseudomonas aeruginosa in 14 (9.9%), Staphylococcus aureus in eight (5.6%), Serratia marcensens in seven (4.9%), Escherichia coli in four (2.8%), other Enterobacteriaceae in five (3.5%), Pseudomonas spp in three (2.2%), Candida albicans in two (1.4%), and mixed infection in 19 patients (13.4%). In our study, sensitivity of the quantitative culture of BAL was 91%, specificity was 70%, positive predictive value was 80% and negative predictive value was 85%. Conclusions: Quantitative culture of BAL can be useful in VAP diagnosis in patients hospitalized in the ICU, helping in the discrimination between colonization and the infection.

Cheesemaking is one of the most complex technologies in dairy and cheese science as a product of this art enjoys a special status among dairy products thanks to its high-value ingredients. Facts about rich cheese culture and tradition affect the modern consumer society, occupied by brands and consumers, as a result, are no longer satisfied only with good products. Thus, cheese is ideal product for modern consumers. Upon this the idea of joining cheese and traditional Bosnian product - the prune was born. In this research the experimental preparation of thermally - acidic coagulating cheese with the addition of prune is presented with the assumption that this cheese is acceptable for consumers. The cheese was tested for chemical composition and the quality parameters and it is shown that the quality parameter values correspond to heat-acid coagulating cheese type. In order to examine the shelf life of the product cheese was stored for 5 and 10 days and the changes of that samples occurred were noted. As a fundamental part of the research to determine the acceptability of the product sensory analysis was performed and the research showed that the experimental product was 95% acceptable by consumers and 100% acceptable by panel of expert evaluators. The cheese cannot be stored for a long time and it is proper to be consumed in a fresh state.

: The low degradability of waste materials containing lignocellulosic material is one of the factors that hinder the production of biogas. The increased need for advanced techniques in the anaerobic digestion process has led to the use of different pretreatment raw materials prior to the anaerobic digestion process in order to increase the yield of biogas. In order to maximize the yield of biogas from cattle manure in a mixture with waste sludge, the anaerobic digestion process was performed at mesophilic conditions for 54 days. As pretreatment, the thermal treatment of cattle manure at temperatures of 55 and 70 °C was applied. The highest biogas production was obtained in the sample of cattle manure, previously treated at 70 °C (M70), while the lowest was recorded in the control sample M. The specific biogas production in relation to the input quantity of volatile organic matter had the highest value in sample M70 and the lowest in the control sample. Overall results have shown that the thermal treatment of cattle manure before the anaerobic digestion process can increase both yield

In the CERN IT agile infrastructure (AI), Puppet, the CERN IT central messaging infrastructure (MI) and the Roger application are the key constituents handling the configuration of the machines of the computer centre. The machine configuration at any given moment depends on its declared state in Roger and Puppet ensures the actual implementation of the desired configuration by running the Puppet agent on the machine at regular intervals, typically every 90 minutes. Sometimes it is preferable that the configuration change is propagated immediately to the targeted machine, ahead of the next scheduled Puppet agent run on this machine. The particular need of handling notifications in a highly scalable manner for a large scale infrastructure has been satisfied with the implementation of the CERNMegabus architecture, based on the ActiveMQ messaging system. The design and implementation of the CERN-Megabus architecture are introduced, followed by the implementation of the Roger notification workflow. The choice of ActiveMQ is analysed and the message flow between the Roger notification producer and the CASTOR, EOS, BATCH and Load Balancing consumers are presented. The employment of predefined consumer modules in order to speed up the on-boarding of new CERN-Megabus use cases is also described.
