MICROPLASTICS IN THE ENVIRONMENT AND IMPACT ON HUMAN HEALTH
No full textMikroplastika je naziv za plastične čestice promjera manjeg od 5 milimetara. Iako su čestice mikroplastike male, kada se nađu u oceanu ili sedimentu, opasan su oblik onečišćenja. Sveprisutan je u okolišu i svakodnevnom životu. Može se pronaći u raznim kozmetičkim preparatima kao što su paste za zube, pjene za brijanje, gelovi za tuširanje i drugi slični proizvodi. Prisutnost mikroplastike može izazvati ozbiljne probleme u prehrambenom lancu jer se na njihovim površinama mogu nakupljati razne otrovne tvari koje ribe mogu unijeti, primjerice, u svoj probavni trakt. Na taj način organizmi koji žive u vodenom okolišu imaju potencijal akumulirati toksine, čineći mikroplastiku opasnom za ljude. Mikroplastika se također može proizvoditi u okolišu jer se veći plastični fragmenti usitnjavaju i razgrađuju pod utjecajem slane vode, ultraljubičastog zračenja, oceanskih valova i drugih abiotičkih čimbenika. Mnogi znanstvenici i stručnjaci rade na rješavanju ovog problema, nadajući se da će teško razgradivu plastiku zamijeniti novim, ekološki prihvatljivijim materijalima.Microplastic is the name for plastic particles with a diameter of less than 5 millimeters. Although microplastic particles are small, once they are in the ocean or sediment, they are a dangerous form of pollution. It is omnipresent in the environment and in everyday life. It can be found in various cosmetic preparations such as toothpastes, shaving foams, shower gels and other similar products. The presence of microplastics can cause serious problems in the food chain because various toxic substances can accumulate on their surfaces, which fish can introduce, for example, into their digestive tract. In this way, organisms living in the aquatic environment have the potential to accumulate toxins, making microplastics dangerous for humans. Microplastics can also be produced in the environment as larger plastic fragments break down and break down under the influence of ultraviolet radiation, salt water, ocean waves and other abiotic factors. Many scientists and experts are working to solve this problem, hoping to replace hard-to-degrade plastics with new, more environmentally friendly materials

THERMAL EFFECTS AND TRACES OF FIRE AND/OR EXPLOSION IN CLOSED SPACE
No full textSvaki požar predstavlja nekontroliranu i nepredvidivu pojavu. Kad je vatra u zatvorenom prostoru, opasnost se povećava jer vatra ne može slobodno rasti i izmjenjivati energiju s okolinom. Toplina i dim se ne odvode na odgovarajući način, smanjuje se količina kisika, počinju se stvarati opasne tvari koje se mogu zapaliti. Razumijevanje učinaka topline, tragova vatre i eksploziva u zatvorenim prostorima ključno je za razotkrivanje uzroka incidenata. Učinci topline mogu iza sebe ostaviti jasne tragove koji nude dragocjene uvide u okolnosti požara ili eksplozije. Tragovi vatre i eksploziva daju forenzičkim stručnjacima ključne dokaze za spajanje događaja koji su doveli do incidenta. Ovaj se rad daje pregled mogućih toplinskih učinaka te interakcije topline s različitim okruženjima, identifikacijom ostataka i implikacijama za istraživanja uzroka i okolnosti nastanka požara u zatvorenim prostorima.Every fire is an uncontrolled and unpredictable phenomenon. When a fire is in a closed space, the danger increases because the fire cannot grow freely and exchange energy with the environment. Heat and smoke are not removed adequately, the amount of oxygen decreases, and dangerous substances that can ignite begin to form. Understanding the effects of heat, traces of fire and explosives in closed and semi-open spaces is essential to unraveling the causes of incidents. The effects of heat can leave behind clear clues that offer valuable insights into the circumstances of a fire or explosion. Traces of fire and explosives provide forensic experts with key evidence to piece together the events that led to the incident. This paper provides an overview of possible thermal effects and the interaction of heat with different environments, identification of remains, and implications for research into the causes and circumstances of fires in closed and semi-open spaces
THE ORGANIZATIONAL CULTURE AS AN IMPORTANT INTERNAL FAKCTOR IN HUMAN RESOURCE MANAGEMENT
No full textKultura, kao društveni fenomen, jedan je od najvažnijih pojmova za svakog pojedinca. Kultura spaja ljude koji ju dijele te daje ljudima osjećaj zajedništva i pripadnosti. Stvaranjem dobre organizacijske kulture zaposlenici osjećaju pripadnost organizaciji, stvaraju organizacijski identitet i organizacijsku klimu koja potiče timski rad i kreativnost. Poslovna kultura dobiva sve više na značaju zbog njezinog snažnog utjecaja na poslovanje i poslovne rezultate a utemeljena je na suvremenoj znanosti i tehnologiji. Danas je gotovo obaveza poslovati izvan granica svoje države i zapošljavati ljude iz raznih dijelova svijeta. Tako se kulture isprepliću i ljudi sve više uče, saznaju i otkrivaju razne kulture. Za uspjeh je bitno poznavanje pravila poslovnog ponašanja i poslovnih običaja, koji se razlikuju ne samo od kontinenta do kontinenta, od države do države, unutar same države nego čak i od kompanije do kompanije. Zbog svakodnevne interakcije i ispreplitanja mnogih kultura, specifične vrijednosti i ponašanja gube svoju specifičnost i postaju ponekad i trendovi. Europa i Sjedinjene Američke Države (u nastavku SAD) čine dvije trećine globalne trijade. To su dva najveća konkurenta i istodobno jedni od najpovezanijih poslovnih partnera u smislu razmjene dobara. Osim dobara, interakcijom se razmjenjuju i poslovni običaji, vrijednosti i kultura, sve to kako bi se bolje snalazili na konkurentskom teritoriju i kako bi učili poslovati što efikasnije primjenjujući te spoznaje na svome teritoriju. Takva internacionalna interakcija može se promatrati na primjeru koncerna Flowserve, koji je prije 230 godina osnovan u Londonu, širio se tijekom vremena po Europi i na kraju se smjestio sa sjedištem u SAD. Sa više od 200 poslovnica u preko 50 zemalja svijeta, 16 000 zaposlenih i čak 9 službenih jezika, čini zanimljivu mješavinu najrazličitijih kultura svijeta koje pokušava objediniti, barem djelomično, jednom univerzalnom poslovnom kulturom sa unaprijed definiranom misijom, vrijednostima i ponašanjima.Culture, as a social phenomenon, is one of the most important concepts for every individual. Culture connects people who share it and gives them a sense of community and belonging. By creating a positive organizational culture, employees feel a sense of belonging to the organization, establish organizational identity, and foster an organizational climate that promotes teamwork and creativity. Business culture is becoming increasingly significant due to its strong impact on business operations and results, and it is founded on modern science and technology. Today, it is almost mandatory to operate beyond the borders of one's country and to employ people from various parts of the world. Thus, cultures intertwine, and people increasingly learn, discover, and understand different cultures. It is crucial to understand the rules of business conduct and customs in order to be successful, and they vary not only from continent to continent, from country to country, within a single country but even from company to company. Due to the daily interaction and intertwining of many cultures, specific values and behaviors lose their specificity and sometimes become trends. Europe and the United States of America (hereafter referred to as the USA) form two-thirds of the global triad. They are the two largest competitors and simultaneously some of the most connected business partners in terms of goods exchange. Besides goods, business customs, values and cultures are also exchanged through interaction in order to navigate better in competitive territories and to learn to operate more efficiently by applying these insights in their own territories. Such international interaction can be observed in the example of the Flowserve Corporation, which was founded 230 years ago in London, expanded throughout Europe over time, and ultimately established its headquarters in the USA. With more than 200 business locations in over 50 countries worldwide, 16,000 employees, and even 9 official languages, Flowserve represents an interesting mix of the world's most diverse cultures and tries to unify them, at least partially, into a single universal business culture with a defined mission, values, and behaviors
