    No full text
    Kompresor je najsloženiji i najskuplji dio u rashladnom sustavu na brodu, te je on predmet ovog rada. Kompresor komprimira neki plin ili paru na viši tlak, odnosno plinovima ili parama povisuje energetsku razinu. U brodskoj rashladnoj tehnici uglavnom se koriste četiri vrste kompresora, a to su stapni, vijčani, rotacijski i turbokompresor. Iako se najviše upotrebljavaju stapni kompresori, u novije vrijeme se sve više nastoje ugraditi vijčani kompresori zbog njihove manje osjetljivosti na hidraulični udar. U prvom dijelu rada upoznajemo se s rahladnom tehnikom općenito i s ljevokretnim rashladnim ciklusom. U drugom dijelu rada govorimo o regulaciji dobave stapnih, klipnih, vijčanih i turbokompresora, i na kraju rada ćemo obraditi temu o dijagnostici i održavanju kompresora.The compressor is the most complex and expensive part of the ship's refrigeration system, and it is the subject of this paper. The compressor compresses a gas or steam to a higher pressure, or raises the energy level with gases or vapors. Four types of compressors are mainly used in marine refrigeration technology, namely rod, screw, rotary and turbocharger. Although reciprocating compressors are the most widely used, in recent times more and more efforts are being made to install screw compressors due to their lower sensitivity to hydraulic shock. The first part of the paper we are introduced to the cooling technology generally and to the counterclockwise cooling cycle. In the second part of the paper, we talk about the regulation of the supply of rod, piston, screw and turbo compressors, and at the end of the paper we will cover the topic of diagnostics and maintenance of the compressors

    Uvod: Humor je zajednički naziv za verbalne, pisane i crtane iznesene sadržaje koji izazivaju smijeh i dobro raspoloženje; ali je ujedno humor definiran i kao svojstvo osobnosti koja se očituje u duhovitosti. Humor, kao važna značajka za naše zdravlje utječe kako na fizičko tako i na mentalno zdravlje. Pomaže nam u obrani od stresa i negativnog raspoloženja. Pandemija koronavirusa unijela je razne promjene u gotovo svaki životni aspekt ljudske svakodnevnice pa tako ni društvene mreže nisu bile izostavljene. Svi su htjeli znati sve o novonastalom virusu i bolesti koja nastaje zbog njega, a stručnjaci i znanstvenici nisu imali odgovore na pitanja koja je postavljala uplašena javnost. Cilj rada: Istražiti kako je humor djelovao na ispitanike u doba pandemije COVID-19 tijekom karantene. Ispitivanje njegove funkcije kao zabave, lijeka i općenito podnošenja pandemije COVID-19 te iste te rezultate prikazati statistički i opisno u ovome radu. Ispitanici i metode: U istraživanju putem online ankete sudjelovala je 103 ispitanika dobnih skupina između 20 i 50 godina. Obuhvaćeni su studenti Sveučilišta u Dubrovniku, zaposlenici Opće bolnice Dubrovnik te Doma zdravlja Dubrovnik. Anketni upitnik sastojao se od desetak pitanja. Pitanja su obuhvaćala: spol, dob, stručnu spremu, koliki je strah od zaraze na skali od 1 do 10 te utjecaj humorističkih sadržaja na temu pandemije bolesti COVID-19. Rezultati: Rezultati istraživanja pokazalo da je čak 70,9% ispitanika izjavilo da im je uz humoristični sadržaj vrijeme brže prolazilo. Sljedećih 39,8% ispitanika su poboljšali komunikaciju s ukućanima, a 33% ispitanika je poboljšalo komunikaciju s prijateljima. Rasprava: Dobiveni podaci ovog istraživanja pokazuju kako je COVID-19 i karantena utjecala na živote ljudi svih dobnih skupina. Potrebno je istaknuti da su slične teme općenito slabo obrađivane, te su aktualna literatura i slična istraživanja bila teško dostupna. Zaključak: Humor je zaista lijek ne samo u teškim duševnim trenutcima, već i pogodno djeluje na fizičko zdravlje ljudi. Ponašao se kao anksiolitik, a moglo bi se reći čak kao i sedativ u nekim slučajevima. Zaključak je da se humor pokazao kao lijek u doba krize navedene pandemije koronavirusa.Introduction: Humor is a common name for verbal, written and cartoon content that causes laughter and good mood; but at the same time, humor is also defined as a personality trait that manifests itself in wit.

    U ovom završnom radu opisane su metode zaštite od požara na putničkim brodovima koje se odnose na sprječavanje požara, njegovo otkrivanje, te gašenje. S obzirom na specifične karakteristike putničkih brodova i mogućnosti nastanka razornih posljedica uzrokovanih požarom, a koje uključuju štete na brodu, teretu i ekosustavu, te velike gubitke ljudskih života, zahtjevu zaštite od požara kao važnom čimbeniku sigurnosti broda potrebno je udovoljiti prilikom samog dizajna broda. S vremenom su definirani zahtjevi koji se stalno nadopunjuju i ažuriraju na temelju novih spoznaja i saznanja kojim putnički brodovi moraju udovoljavati. Ti su zahtjevi propisani SOLAS konvencijom a sastoje se od skupa pravila o zaštiti od požara, njegovog otkrivanja i gašenja.This final paper describes fire protection methods on passenger ships related to preventing, detecting and extinguishing fires. Considering the specifics of passenger ships and the possibility of devastating consequences caused by fire, which include damage to the ship, cargo and ecosystem, as well as loss of human life, the requirement of fire protection as an important factor of ship safety must be met during the design of the ship itself. Therefore, over time, requirements have been defined that are constantly supplemented and updated based on new knowledge and findings that passenger ships must meet. These requirements are prescribed by the SOLAS convention and consist of a set of fire protection rules, detection and extinguishing

    Financijska stabilnost bankarskog sektora smanjuje mogućnost nesolventnosti u budućnosti. Kontinuirano praćenje zdravlja bankarskog sektora ključni je dio procjene stabilnosti nacionalnih financijskih sustava. Države članice Europske unije provode različite politike kojima nastoje ograničiti potencijalne rizike. Gotovo svi regulatorni zahtjevi uključuju osiguranje više kapitala, tj. jačanje kapitalne osnovice banke. Cilj rada jest razmotriti pitanje financijske stabilnosti i adekvatnosti kapitala u sektoru bankarstva te analizirati kapitaliziranost hrvatskih banaka i europskih banaka. Analiza je pokazala da su europske banke nastavile graditi solidnu poziciju kapitala i jačanja imovine, što je rezultiralo otpornošću bankarskog sektora.The financial stability of the banking sector reduces the possibility of insolvency in the future. Continuous monitoring of the health of the banking sector is a key part of assessing the stability of national financial systems. The Member States of the European Union pursue various policies that seek to limit potential risks. Almost all regulatory requirements include ensuring more capital, ie strengthening the bank's capital base. The aim of this paper is to consider the issue of financial stability and capital adequacy in the banking sector and to analyze the capitalization of Croatian banks and European banks. The analysis showed that European banks continued to build a solid position of capital and strengthen assets, resulting in the resilience of the banking sector
