Preliminary Proposal for New Traffic Flow Regulation and Organization in Brodarica in the City of Šibenik

Kretanje pojedinačnog vozila na prometnici je kretanje vozila na cesti najvećom sigurnosnom brzinom, a nije ovisno o drugim vozilima na prometnici. Za razliku od pojedinačnog kretanja vozila, pod prometnim tokom se razumijeva kretanje dvaju ili više vozila na istom putu. Odnosi među prometnim tokovima na raskrižjima jedan su od uzroka smanjene propusne moći. Zbog toga svaki postupak u izmjeni organiziranosti prometnih tokova mora biti utemeljen na detaljno izučenom postojećem stanju i sagledavanju njegove izmjene. Takav problem vidljiv je u mjestu Brodarica kod Šibenika. Pogrešna organizacija prometa dovodi do nepotrebnih presijecanja prometnih tokova. Svrha istraživanja je analizirati postojeće prometne tokove u naselju Brodarica,te ukazati na probleme koji se javljaju pri odvijanju prometa. Cilj istraživanja je prikupiti podatke brojanjem prometa i ponuditi nova rješenja kako bi se smanjio broj nepotrebnih presijecanja, smanjili repovi čekanja,povećala propusna moć te sigurnost svih sudionika u prometu.The movement of an individual vehicle on the road is the movement of the vehicle on the road at highest safety speed and independently of any other vehicles on the road. Unlike single-vehicle movement, traffic flow implies the movement of two or more vehicles on the same path. The relation between traffic flows at intersections is one of the causes of reduced throughput capacity. Therefore, any procedure of modification of organization of traffic flows needs to be based on troughly studying in the existing situation and reviewing its modification. Such problem can be seen in Brodarica near Šibenik. Incorrect organization of traffic leads to unnecessary intersecting of traffic flows. The purpose of the research is to analyze the existing traffic flows in Brodarica and to point out the problems that occur in the traffic flow. The goal of the research is to collect data by counting traffic and to offer new solutions that would reduce the number of unnecessary intersections, queue lenghts and increase throughput capacity and safety of all traffic participants

Fenotipska i genetska povezanost osobina plodnosti plotkinja švedskog landrasa

The aims of this paper were: determination of correlation between fertility traits both at phenotypic and at genetic level, determination of dependency of exsamined parameters from the analysed data size as well as determination of influence of data corrections on correlations between traits. Phenotypic correlation between litter size and weight did not confirm after correction for NWP and LWW. Between NLB and NTB phenotypic correlation was complete (from rP=0.922 to rP=0.929) and statistical very significant (P lt 0.01). Genetic correlation among traits were in range from low (rG=0.230, NWP:TNB) to complete (rG=1.197, cNWP:NLB). So wide range for genetic correlation was consequence of analyzed data set. Statistical significance for obtained parameters were high (P lt 0.01).Cilj ovog rada bio je da se utvrdi povezanost između osobina plodnosti na fenotipskom i genetskom nivou. da se utvrdi zavisnost ispitivanih parametara od obima analiziranih podataka kao i uticaj sprovedenih korekcija podataka na povezanost između osobina. Fenotipska povezanost osobina veličine i mase legla nije ustanovljena posle sprovedenih korekcije za BOP i MLPO. Između BŽRP i BURP fenotipska povezanost je bila potpuna (od rp=0.922 do rp=0.929) i statistički visoko značajna (P lt 0.01). Genetske korelacije su se kretale od jako slabe (rG=0.230, KBOP:BURP) do potpune (rG=1.197, KBOP:BŽRP) što je zavisilo od osobina i korišćenih podataka u analizi. Statistička značajnost utvrđenih parametara je bila visoka (P lt 0.01)

Nanofiltration of a Landfill Leachate Containing Pharmaceutical Intermediates from Vitamin C Production

The main landfill of the city of Zagreb generates several hundreds of cubic meters of heavily contaminated leachate per day. The organic composition of the leachate is particularly peculiar because, besides common macromolecular humus-like dissolved organic carbon,it encompasses a number of specific compounds of pharmaceutical origin, including a suite of by-products deriving from the production of vitamin C. Since both macromolecular humic organic matter and vitamin C intermediates are rather resistant to microbial degradation, leachate treatment procedures using simple retention lagoons or conventional bioreactors are not very effective in reducing their levels before the discharge into the receiving waters. An attractive alternative is the application of membrane technology. The efficiencies of three different types of nanofilters for the purification of leachates from the Jakuševec landfill were examined. It was shown that both complex humic-like dissolved organic matter and anthropogenic compounds of pharmaceutical origin can be eliminated at high efficiencies, mostly above 90 %

Reproductive Performances of Holstein Cows with Different Milk Fat to Protein Ratio during Successive Stages of Lactation

Aim of study was to determine relationship between the energy status of cows, expressed through different milk fat to protein ratio values (FPR<1.0, 1.0-1.3 and >1.3), and their reproductive performances (interval from calving to first artificial insemination; calving to conception interval; insemination index; pregnancy duration; intercalving interval) during succesive stages of lactation (day 15th to 45th; day 46th-75th; day 76th-105th; day 106th to 135th of lactation). The study included a total of 350 fresh calved Holstein cows (121 primiparous, 115 secundiparous and 114 cows which calved three or more times), kept and fed in usual farm conditions. Milk samples were taken during morning milking, and FPR value was calculated from concentrations of milk fat and protein for all milk samples. Reproductive parameters were calculated from farm data. Values of all reproductive parameters, except pregnancy duration, had generally increasing trend in all groups during successive stages of lactation. During successive stages of lactation, cows with optimal FPR values had generally better reproductive performances, compared to cows with increased or decreased FPR values, which indicates importance of FPR monitoring during early lactation for timely detection of cows predisposed for poor reproductive results

Produžen anestrus post partum i reproduktivna performansa muznih krava (pregled)

Tokom  nekoliko zadnjih decenija, genetski napredak u proizvodnji mleka, povezan sa primenom novih reproduktivnih tehnologija, doveo je do značajnog smanjenja fertiliteta u zapatima krava visoke mlečnosti širom sveta. Produžen postpartalni anestrus je jedan od glavnih uzroka smanjenog fertiliteta i ekonomskih gubitaka u intenzivnoj proizvodnji mleka. Cilj ovog rada je da se prikažu uzroci i mogućnost smanjenja uticaja ovog faktora na sledeću reproduktivnu performansu visoko mlečnih krav

Sedative poisoning - eight-year retrospective study in the Centre of Emergency Medicine Clinical Hospital "Sveti Duh"

U radu je retrospektivno analizirana učestalost bolesnika zaprimljenih u Centar za hitnu medicinu – Središnji hitni prijam KB „Sveti Duh” zbog trovanja sedativima u razdoblju od siječnja 2008. do rujna 2015. godine. Analizirani su demografski podaci bolesnika, vrste sedativa kojima je izvršeno trovanje, te klinička simptomatologija, terapijski postupci i ishod liječenja. Podaci su prikupljeni iz baze podataka informatičkog bolničkoga sustava, te arhive medicinske dokumentacije. Istraživanje je obuhvatilo 444 bolesnika. Najveći broj bolesnika zaprimljenih zbog trovanja bio je u dobnoj skupini od 36 do 55 godina (50%). S obzirom na spol, veći je udio žena (64%), a najčešći uzročnik trovanja bio je diazepam (67,1%). Kod najvećeg broja otrovanih bolesnika nije bilo značajnih kliničkih simptoma (31%) ili je bila izražena blaga somnolencija, sedacija ili pospanost (45%). U 87% bolesnika primijenjena je infuzijska terapija kristaloidnim otopinama, a u 55% njih antidot flumazenil. Najveći broj bolesnika (81%) bio je zadržan na promatranju do nestanka simptoma, te nakon toga upućen u nadležnu psihijatrijsku ustanovu. Smrtni ishod zabilježen je kod 8 bolesnika. U zaključku možemo naglasiti da trovanja sedativima predstavljaju značajan problem za sve liječnike koji rade u hitnoj medicinskoj službi. Iako većina bolesnika ne zahtijeva hospitalizaciju i nema izraženu težu kliničku simptomatologiju, 8 umrlih bolesnika ukazuje na široku dostupnost sedativa, a time i potrebu za boljom regulacijom propisivanja, kao i potrebu za stalnom edukacijom u zbrinjavanju istih.The study retrospectively analyzed sedative poisoning among patients admitted to the Centre of Emergency Medicine of Clinical Hospital “Sveti Duh" from January 2008 to September 2015. Patients’ demographic, sedative medication type, clinical symptoms, therapeutic procedures and outcomes were analysed. Data were collected from the hospital medical information system, and from the patients\u27 medical records. The study included 444 patients. The majority of patients were between 36 to 55 years of age (50%). In relation to gender, a greater number of cases occurred in female patients (64%) and the most frequently ingested drug was diazepam (67.1%). Most patients had no clinical manifestation of poisoning (31%) or just relatively mild symptoms included sedation, drowsiness and mild somnolence (45%). For the treatment, 87% of patients received IV solution and 55% received antidote flumazenil. The majority of patients were kept under observation until signs and symptoms of poisoning had been resolved, and then sent to psychiatric hospitals. Deaths were recorded in 8 patients. In conclusion, we need to emphasize that the acutely poisoned patient remains a common problem facing doctors working in the Emergency Department. Although, most poisoned patients do not requirehospitalization and do not have significant clinical symptoms, the widespread use and availability of sedatives resulted in 8 deaths. This high rate of mortality indicated the need for better control and more restrictions on prescribing sedatives and continuing education in the management of these patients
