No full textTemom tržišno pozicioniranje proizvoda Zvijezda ulja pokušat će se dokazati važnost pozicioniranja proizvoda u svijesti potrošača. Rad je podijeljen u četiri dijela. U prvom poglavlju su obrađeni neki osnovni marketinški pojmovi kao što su: marketing koncepcija, upravljanje marketingom te marketing kao proces. Unutar marketing procesa objašnjene su faze samog procesa. Unutar faze planiranja marketing programa navedene su i detaljno objašnjene sve faze unutar marketing miksa. Drugo poglavlje dotiče se tržišnog pozicioniranja te nudi izbor i kriterije pozicioniranja. Svaki proizvod ili usluga moraju imati jasno određen položaj na tržištu. Položaj u mislima potrošača predstavlja složeni skup percepcija, dojmova i osjećaja po kojima se jedan proizvod razlikuje od drugoga. Poduzeća se trude pozicioniranje ne prepustiti slučaju, već kreiraju marketinške strategije koje njihovim proizvodima ili uslugama daju najveću prednost na odabranom ciljnom tržištu. Strategija pozicioniranja kreira naklonost potrošača prema proizvodu i potrošačima olakšava izbor proizvoda. U trećem poglavlju obrađen je poslovni slučaj Zvijezde d.d. i primjena strategije pozicioniranja na Zvijezda uljima. Posljednji,četvrti dio posvećen je zaključku u kojem se sažeto iznose bitni podaci o istraživanoj temi uz osobni osvrt autora te preporučenu strategiju.The theme of market positioning of Zvijezda oil will try to prove the importance of product positioning in the minds of consumers.

Production and stabilization of cold-pressed hemp oil with the addition of antioxidants and synergist
No full textU ovom radu istraživan je utjecaj procesnih parametara hladnog prešanja konoplje na iskorištenje konopljinog ulja. Prešanje konoplje provedeno je na laboratorijskoj kontinuiranoj pužnoj preši. Prilikom prešanja mijenjani su procesni parametri: veličina otvora glave preše, temperatura zagrijavanja glave preše, frekvencija elektromotora. Nakon prešanja provedeno je prirodno taloženje i vakuum filtracija sirovog ulja. Primjenom standardnih metoda određeni su osnovni parametri kvalitete proizvedenog ulja: peroksidni broj, slobodne masne kiseline, udio netopljivih nečistoća te udio vlage. Također, cilj ovog rada je bio odrediti oksidacijsku stabilnost konopljinog ulja sa i bez dodatka antioksidanasa i sinergista Testom održivosti pri 98 °C. Rezultati su pokazali da promjena procesnih parametara utječe na iskorištenje konopljinog ulja kao i da se dodatkom mješavine antioksidanasa i sinergista postiže veća zaštita ulja od oksidacijskog kvarenja.In this thesis author tested influence of process parameters of cold hemp pressing on the utilization of hemp oil. Pressing hemp was conducted on laboratory continuous worm press. During the molding process parameters that were changed are: the size of the head press opening, the heating temperature of the head presses, electric motor frequency. After pressing, natural sedimentation was conducted and vacuum filtration of crude oil. Using standard methods basic quality parameters of produced oil are defined like: peroxide value, free fatty acids, the proportion of insoluble impurities and moisture. Second objective of this research was to determine the oxidative stability of hemp oil with and without the addition of antioxidants and synergist Test viability at 98 °C.

Influence cold pressing walnut on utilization of oil and rheological properties spread of walnut johnnycake
No full textU ovom radu istraživan je utjecaj procesnih parametara hladnog prešanja oraha na iskorištenje orahovog ulja. Prešanje jezgre oraha provedeno je na laboratorijskoj kontinuiranoj pužnoj preši. Prilikom prešanja mijenjani su procesni parametri: nastavak za izlaz pogače, temperatura glave preše i brzina pužnice. Nakon prešanja provedeno je prirodno taloženje i vakum filtracija sirovog ulja. Primjenom standardnih metoda određeni su osnovni parametri kvalitete proizvedenog ulja: peroksidni broj, slobodne masne kiseline, udio netopljivih nečistoća te udio vlage. Također, cilj ovog rada je ispitati utjecaj sastojaka na reološka svojstva namaza od orahove pogače. Mjerenja reoloških svojstva su provedena na rotacijskom viskozimetru s koncentričnim cilindrima pri temperaturi od 60 ˚C. Iz dobivenih podataka su izračunati reološki parametri namaza: indeks tečenja, prividna viskoznost i koeficijent konzistencije. Dobiveni rezultati ukazuju da ispitivani procesni parametri prešanja oraha utječu na iskorištenje ulja. Također, iz rezultata može se zaključiti da namaz od orahove pogače pripada ne-Newtonskim sustavima. Veća viskoznost namaza se postiže dodatkom kakao praha, dok manju viskoznost ima namaz od jezgre oraha. Manja se viskoznost namaza postiže sa smanjenjem uljne faze.In this thesis author researches the influence of process parameters of cold pressing walnut on utilization of walnut oil. The pressing of walnut core was conducted on a laboratory continuous worm screw press. During pressing following process parameters varied: johnnycake output extension, press head temperature and cochlea frequency. After pressing, natural sedimentation was conducted and vacuum filtration of crude oil. Walnut oil quality parameters were determined applying standards methods: peroxide number, free fatty acids, the proportion of insoluble impurities and moisture. Second goal of this thesis is to examine the influence of ingredients to the reological properties of spread walnut johnnycake. Measurements on reological properties were conducted on rotation viscosimeter with circular cylinder at a temperature of 60 ˚C. From conducted experiment following reological butter parameters were calculated: flow index, apparent viscosity and consistent coefficient. The results showed that the studied process parameters pressing walnut affect utilization of oil. From obtained data, it is possible to conclude that spread belongs to non-Newtonian systems. Greater viscosity was gained by cocoa powder, while walnut core has lower viscosity. With reduction in the oil phase you achieve lower viscosity of spread
Zelena priča o alkil poliglikozidima
No full textSurfactants are substances of specific chemical structure which are capable of reducing the surface tension of liquid they are dispersed; they are basic ingredients of the widely used products such as detergents, cosmetics, paints and pesticides and many petroleum products. The green surfactants are surface active agens which are obtained from natural oils (for example palm or coconut oil) as well as plant carbohydrates (for example polysaccharides from marine algae) and they are main ingredients of both biodegradable and biocompatible products. Their use is a response to growing consumer demands for products that are 'greener', milder and more efficient, due to which green surfactants derivation from natural renewable resources is the concept that is increasingly used in industry of detergents and cosmetics. In this context, alkyl polyglucosides (APG) are key green surfactants whose use is an excellent solution for manufacturers who aim to combine efficiency and safety in the final product. In this paper, the author gave a short overview of alkyl polyglycosides as well as further perspective in their uses.Surfaktanti su supstance specifične hemijske strukture koje smanjuju površinski napon tečnosti u kojoj su rastvoreni ili dispergovani; oni su osnovni sastojci široko korišćenih proizvoda kao što su detergenti, kozmetički preparati, boje i pesticidi, a mnogi su naftni derivati. Zeleni surfaktanti su površinski aktivne materije koje se dobijaju iz biljnih ulja (npr. iz palminog ili kokosovog ulja) i biljnih ugljenih hidrata (npr. šećerne trske ili žitarica) i predstavljaju osnovne sastojke različitih biorazgradivih i biokompatibilnih proizvoda. Njihovo korišćenje je odgovor na sve veću potražnju potrošača za proizvodima koji su 'zeleniji', blaži i efikasniji, zbog čega je dobijanje zelenih surfaktanata iz prirodno obnovljivih izvora koncept koji se sve više koristi u industriji detergenata i kozmetici. U ovom kontekstu, alkil poliglikozidi (APG) su ključni zeleni surfaktanti čija upotreba predstavlja odlično rešenje za proizvođače čiji je cilj kombinovanje efikasnosti i bezbednosti u finalnom proizvodu. Ovo je priča o njima
A CONTRIBUTION TO THE INTERPRETATION OF MATIJA SKURJENI'S PAINTING
No full textOvo je fragment veće studije o Matiji Skurjeniju (1898. -1990.) koja će biti objavljena u Njemačkoj u povodu stogodišnjice umjetnikova rođenja. Pisana je za potrebe Muzeja Charlotte Zander u Bonningheimu, u čijoj je kolekciji šezdeset ulja te četrdesetak crteža i serigrafija našeg majstora. - Na temelju strukturne analize slike Dječak koji voli golube (1960) autor raspravlja o umjetnikovu oslobađanju od stega kauzalnosti radnje, vremena i prostora, o ispremiješanosti racionalnog i iracionalnog, logike i fantastike, stvarnog i nestvarnog, sna i jave. Te promjene, koje se u Skurjenijevu stvaralaštvu počinju iskazivati 1957./58., dovode se u vezu s novim slikarovim životnim iskustvima - povezivanjem s povjesničarom umjetnosti, likovnim kritičarom i pjesnikom Mičom Bašičevićem, voditeljem Galerije primitivne umjetnosti u Zagrebu, koji je mentorskim djelovanjem usmjerio umjetnika prema podsvjesnom, čudesnom i aluzivnom, fantastičnom, simboličnom i onostranom.The author presents a fragment of a larger study about Matija Skurjeni (1898-1990) to be published in Germany for the Charlotte Zander Museum in Bonnigheim - (which owns sixty oil paintings and about forty drawings and serigraphs of the artist) - on the occasion of the hundredth anniversary of the artiste birth. Starting with an analysis of the painting The Boz Who Loveses pigeons(t969), the author discusses the artista liberation from the rules of causality, from time and space, by mixing the rational and irrational, the logical and fantastic, the real and unreal, dream and reality. This tendency, which began to appear in Skurjeni's painting in 1957/58 is brought in relation with certain events in the artist's life, primarily his association with the art historian, critic and poet Mićo Bašičević, head of the Museum of Primitive Art in Zagreb, who became his mentor and encouraged him to probe the depths of subconscious, magic and allusive, fantastic, symbolic and transcendent experience. In his painting the artist transforms the rational into the unreal and irrational, the impossible becomes possible, imagination becomes reality. Skurjeni paints the reality of the unreal

Maritime Code - significant act with some reproach and dilemma
No full textBez obzira na to što je Pomorski zakonik RH vrlo uspjela kodifikacija, autor zamjećuje neke propuste u tekstu koji su katkad i rezultat tehničke pogreške, ali svakako mogu izazvati razne dvojbe u pravnom dosegu.
U radu se izdvaja odgovornost brodara zbog tjelesne ozljede ili smrti člana posade, naglašavaju se neki lapsusi u području općeg ograničenja odgovornosti brodara, odgovornosti brodara za štete na stvarima i za zakašnjenje, te se upozorava na jedan propust u uporabi izraza u jednom od razloga za oslobođenje od odgovornosti brodovlasnika u slučaju onečišćenja od broda izlijevanjem ulja koje se prevozi kao teret.Although the Croatian Maritime Code is a very successful codification, the author percieves certain mistakes in the text which are sometime the result of technical omissions (lapsus calami), yet may undoubtedly cause various dilemmas of legal scope.
This paper points out the problem of the operator's liability for damages arising from death or personal injuries of a crew member. It also emphasizes lapsuses in the field of the general limitation of the operator's liability, liability both for the damages caused to the goods and for delays. It warns against the use of one of the terms of the non-liability cause for oil pollution damage outside the ship carrying oil
Ecological and legal consequences in the use of propulsion fuels for decreasing sulfur content
No full textAutorica u radu razmatra ekološke i pravne posljedice uporabe brodskog pogonskog goriva sa smanjenim sadržajem sumpora na smanjenje emisija SO2 s brodova. Analizirajući učinkovitost pravnih instrumenata za provedbu zaštite zraka na međunarodnoj i europskoj razini, autorica uspoređuje rješenja Priloga VI. MARPOL-konvencije s rješenjima sekundarnog zakonodavstva Europske unije (direktive 1999/32/EZ, direktive 2005/33/EZ, direktive 2012/33/EZ te Provedbene odluke Komisije (EU) 2015/253) te uspješnost njihova prenošenja u hrvatski pravni sustav. Ukazujući na institucionalni okvir te međunarodne i europske pravne propise, autorica iznosi važeći međunarodni sustav odgovornosti za štetu zbog onečišćenja morskog okoliša izlijevanjem brodskog (pogonskog) goriva s broda (neovisno o sadržaju sumpora u tom gorivu) prema rješenjima Međunarodne konvencije o građanskoj odgovornosti za štete izlijevanjem pogonskog ulja iz 2001. god. Sveobuhvatnom analizom problema praktične primjene brodskog goriva sa smanjenim sadržajem sumpora posebno je razmatran utjecaj usklađivanja s europskim ekološkim zahtjevima na povećanje troškova pomorskog prijevoza. Autorica naglašava neodrživost prometnog sustava zbog dugogodišnje 90-postotne ovisnosti pomorskog prometa o nafti, tj. o neobnovljivom izvoru energije te upućuje na uporabu alternativnih goriva.The author considers the ecological and legal consequences of the use of marine fuels with reduced sulfur content in the reduction of SO2 emissions from ships. Analyzing the efficaciously of the international and european legal instruments for the implementation of air protection, the author compares the solutions of Annex VI. MARPOL Convention with secondary EU legislation (Directive 1999/32/EC, Directive 2005/33/EC, Directive 2012/33/EC and Commission Implementing Decision (EU) 2015/253) and the success of their transfer to the croatian legal system. Noting on the institutional framework of the international and european legislation author outlines valid international system of civil liability for bunker oil pollution damage from ships (regardless of the sulfur content of the fuel) according to solutions of the International Convention on Civil Liability for Bunker Oil Pollution Damage, 2001.
With comprehensive analysis problems of practical application of marine fuel with reduced sulfur content it was considered the effect of harmonization with european environmental requirements to increase the cost of sea transport. The author emphasizes the unsustainability of transport system due to many years of 90% strength dependence of the maritime transport on oil, i.e. a non-renewable energy source and points to the use of alternative fuels
Exercise promotes the expression of brain derived neurotrophic factor (BDNF) through the action of the ketone body β-hydroxybutyrate
No full textExercise induces beneficial responses in the brain, which is accompanied by an increase in BDNF, a trophic factor associated with cognitive improvement and the alleviation of depression and anxiety. However, the exact mechanisms whereby physical exercise produces an induction in brain Bdnf gene expression are not well understood. While pharmacological doses of HDAC inhibitors exert positive effects on Bdnf gene transcription, the inhibitors represent small molecules that do not occur in vivo. Here, we report that an endogenous molecule released after exercise is capable of inducing key promoters of the Mus musculus Bdnf gene. The metabolite β-hydroxybutyrate, which increases after prolonged exercise, induces the activities of Bdnf promoters, particularly promoter I, which is activity-dependent. We have discovered that the action of β-hydroxybutyrate is specifically upon HDAC2 and HDAC3, which act upon selective Bdnf promoters. Moreover, the effects upon hippocampal Bdnf expression were observed after direct ventricular application of β-hydroxybutyrate. Electrophysiological measurements indicate that β-hydroxybutyrate causes an increase in neurotransmitter release, which is dependent upon the TrkB receptor. These results reveal an endogenous mechanism to explain how physical exercise leads to the induction of BDNF
