Prevention of occurrence of selected mycotoxins in feed warehouse for milking cows

The aim of this work was to examine the presence of Fusarium toxins in feed for milking cows in summer and winter. Food samples for milking cows were sampled from a cow farm in the vicinity of Nikšić, Montenegro, in winter and summer. The determined concentrations of the examined mycotoxins in the food samples for feeding milking cows were lower than the maximum allowed concentrations prescribed by the Regular Acts of Montenegro. The obtained results indicate that there was no significant difference in the concentrations of the tested mycotoxins in the food for feeding milking cows during the summer and winter periods, which suggests that with good production and storage practices, food can be protected from mycotoxicological contamination, and cow's milk and meat

Pekel shows how to affirm puppetry in Croatia

Pisca znamo osobno, a ideja da radimo prema tekstu Denisa Perišića sinula je Nikši i meni isprva u obliku ginjolske predstave, međutim tekst je sugerirao jedan drukčiji pristup. Tekst je užasno zanimljiv i vrlo lutkarski. Iako Denis tekst nije izvorno pisao za lutkarsku predstavu, mi smo u njemu pronašli puno lutkarskih elemenata. Ono što je velika šteta jest to da tekst nažalost nikada nije izvođen, a dobio je nagradu Marin Držić, tako da tekst ima užasno velike kvalitete i jako velike potencijale. Mi smo to prepoznali, svidio nam se i krenuli smo raditi s jako velikim entuzijazmom.We knew the author and at first Nikša and I wanted to use the text by Denis Peričić to do a guignol puppet show, but the text suggested a different approach. The text was so interesting and suitable for puppetry. Although Denis had not written it for a puppet show, we found many elements of puppetry in it. Unfortunately, the text was never staged although it won the Marin Držić Award. It was a great text with an enormous potential and we recognised that. The text appealed to us and we set about our work with great enthusiasm

Significance of color doppler ultrasonography in the assessment of pancreatic carcinoma vascular invasion

Background/Aim. It is highly appreciated to provide exact data on vascular invasion of pancreatic carcinoma relying as much as possible on non-invasive diagnostic procedures. Color Doppler ultrasonography has been proven as an efficient method for clinical staging of pancreatic carcinoma essential for therapeutic decisions. The aim of this study was to provide an analysis of the sensitivity and specificity for color Doppler ultrasonography in patients suffering from pancreatic carcinoma. Methods. We performed color Doppler ultrasonography examination in 43 patients with pancreatic carcinoma prior to the surgery. The findings of ultrasonography on neoplasm vascular invasion were correlated to the findings obtained during the subsequent surgical procedures. An estimation of neoplastic invasion of certain blood vessels including portal vein, celiac trunk, and superior mesenteric artery and vein is critical for decision making regarding surgical treatment. The patients with metastases of pancreatic carcinoma were excluded from the study. Results. Comparing color Doppler and the surgical findings we estimated the sensitivity for detection of neoplastic vascular invasion ranging from 79−93%, whereas the specificity range was from 83−93%. Conclusion. Color Doppler ultrasonography is a sufficiently sensitive and specific method for evaluation of vascular invasion in pancreatic carcinoma patients. Since color Doppler ultrasonography is a non-invasive, radiation free, and inexpensive diagnostic tool, considering also the results of this and similar studies we could strongly recommend its use for an initial presurgical evaluation of vascular invasion in pancreatic carcinoma patients

Legislative framework regarding wastewater treatment in the Republic of Serbia and flow and transport modelling in the determination on effluent quality of wastewater treatment plant of Belgrade central sewerage system

The largest sewerage system in Belgrade is Belgrade Central Sewerage System, which covers the area of about 85% of the sewerage network, with about 1,250,000 inhabitants connected to the sewage infrastructure. The interaction of emission limit values, environmental quality standards, wastewater, effluent and recipient characteristic flows and qualities from the standpoint of environmental impact in the unfavorable environmental conditions was modelled to define the level of wastewater treatment at future Belgrade Central Sewerage System wastewater treatment plant

Future quantities of sludge from wastewater treatment plant on the territory of AP Vojvodina

In the framework of the research, an assessment of the future amount of waste sludge that would be generated after the construction of the planned 200 waste water treatment plants (WWTPs) that should be built on the territory of Autonomous Province of Vojvodina in the Republic of Serbia was carried out. It is estimated that the annual production of waste sludge will be slightly more than 81 thousand tons (dry sludge) per year. The methods of sustainable use (circular economy of sludge) and the method of safe disposal of sludge resulting from wastewater treatment were also analyzed. Starting from the possible use in Anaerobic Digestion processes for recharging biogas, the residual sludge from Anaerobic Digestion is excellent for use in agriculture. Well-watered sludge can also be used in the cement production industry, or if the sludge is burned (to reduce the final amount of waste), the ash can be used in the construction industry for the production of bricks or concrete/mortar, and finally sludge has potential for possible use for recharging biofuel, bio-plastic etc. Finally, there is a real potential for the use of waste sludge in AP Vojvodina

FOREIGN TRADE AS A DETERMINANT OF ECONOMIC GROWTH OF THE REPUBLIC OF SRPSKA: AN EMPIRICAL ANALYSIS

Most studies that investigate the relationship between foreign trade and economic growth analyze it through the interpretation of various indicators. This paper seeks to investigate the relationship between coverage of imports by exports and the openness to foreign trade on one hand and the gross domestic product of the Republic of Srpska on other hand. The research relates to the period from 2001 to 2020. By applying the ARDL model we confirmed the initial hypothesis that an increase in the coverage of imports by exports increases the domestic product. The paper confirms the long-term relationship between independent and dependent variables, expressed through the existence of the cointegration equation. Results based on the applied ARDL method show negative, but insignificant relationship between openness and gross domestic product in the Republic of Srpska in long run, and statistically significant positive relationship between coverage of imports by exports and gross domestic product in long run. Value of coefficient shows that 1% increase in coverage of imports by exports increases gross domestic product by 0.80% in long run

5S elementi kao koraci za premošćivanje procepa u procesu prozvodnje transmitera

In this paper, GAP analysis and 5S tool are applied in the case of realization of a compact pressure transmitter. GAP analysis, combined with the 5S tool, can qualitatively indicate the critical points in the manufacturing, assembly and quality control of a finished transmitter. Existing errors lead to the appearance of possible risks in the realization of production processes, from the input of raw materials to the assembly of the finished product. In order to eliminate the existing errors, the main steps of the GAP analysis are described in detail. Guidelines are provided on how to improve the workplace manufacturing process through certain improvements by applying all 5S elements. According to the implemented action plan, the main causes of risk occurrence in the GAP analysis were: human factor and processing technologies. The human factor was characterized by poor control in the workplace (there is no discipline), poor training and incompetence of employees for the given tasks. Processing technology involves obsolete machines, which can introduce deviations of dimensions and tolerances from the prescribed values.U ovom radu, analizirani su GAP analiza i 5S alat na primeru realizacije malogabaritnog transmitera pritiska. GAP analiza, u kombinaciji sa 5S alatom, može kvalitetno ukazuje na kritične tačke u procesu proizvodnje, sklapanja i kontrole gotovog transmitera. Postojeće greške dovode do pojave mogućih rizika u realizaciji proizvodnih procesa, od ulaza repromaterijala do sklapanja gotovog proizvoda. Analiza rizika, omogućava organizaciji da preuzme određene korake u prihvatanju ili smanjenju njegovog uticaja. 5S alat u GAP analizi pomaže da se rizična mesta srede i dovedu u funkcionalno stanje, sa što manje gubitaka (otpada). Zbog eliminacije postojećih grešaka, u radu su detaljno opisani glavni koraci GAP analize. Date su smernice kako da se unapredi proces proizvodnje na radnom mestu kroz određena poboljšanja primenom svih 5S elemenata. Prema sprovedenom akcionom planu konstatovano je da su glavni uzročnici pojave rizika u GAP analizi sledeći: ljudski faktor i tehnologije obrade. Ljudski faktor je okarakterisan slabom kontrolom na radnom mestu (ne postoji disciplina), slabom obukom i nekompetentnošću zaposlenih za propisano radno mesto. Tehnologija obrade podrazumeva tehnološki zastarele mašine i odstupanja mera i tolerancija od propisanih vrednost

Утицај монокултуре на принос зрна соје

Проучавање проблема плодореда у производњи њивских биљака је јако заступљено. Међутим, овај проблем код соје је мање проучаван, како код нас, тако и у свету. У новије време, уобичајени и врло често присутни двопољни плодоред код пољопривредних произвођача у Србији, замењени су тропољним плодоредом са учешћем соје. За разлику од осталих њивских биљака, соја није толико осетљива на гајење у монокултури, посебно краћој. Краткотрајна монокултура (поновљена сетва) соје више утиче на ширење биљних болести и штеточина, док је опадање приноса мање изражено. Циљ овог рада је да на основу резултата истраживања спроведених путем пољског огледа на експерименталној станици Пољопривредног факултета у Земуну ″Радмиловац″ укаже на недостатке гајења соје у дуготрајној монокултури у погледу утицаја на приноса зрна
