    Trans-fatty acids (TFA) are geometric isomers of naturally occurring cis-fatty acids. High dietary TFA intake has been associated with risk factors for cardiovascular disease. However, little is known about TFA levels in humans. To address this data need, we developed and validated a new isotope dilution-gas chromatography-negative chemical ionization-mass spectrometry (ID-GC-NCI-MS) method for quantitation of 27 fatty acids (FA) including 4 major TFA in human plasma, serum, and red blood cells (RBC) from 66 donors. Quantitation was performed with 18 isotope labeled internal standards and results are presented in \u3bcM and % of total FA. This method has high sensitivity and specificity due to use of pentafluorobenzyl-bromide derivatization combined with NCI-MS and a 200m column to optimize positional and geometric FA isomer separation. The four major TFA, palmitelaidic acid, elaidic acid, trans-vaccenic acid, and linoelaidic acid, were detected in all samples, with median total TFA concentrations of 17.7\u3bcM in plasma, 19.6\u3bcM in serum, and 21.5\u3bcM in RBC. The % of total FA for the TFA was 0.20% in plasma, 0.20% in serum, and 0.30% in RBC. Patterns for % FA are similar to those reported in other studies. We developed a highly specific, ID-GC-NCI-MS method to quantitate TFA and other FA in humans.CC999999/Intramural CDC HHS/United States2018-02-28T00:00:00Z29396366PMC5830112vault:2743

    Integracija imigranata u države Europske unije danas je jedno od ključnih društvenih pitanja. Cilj je rada na studiji slučaja kolektiva Okus doma prikazati pokušaje i (ne)uspješnost socioekonomske, kulturne i interakcijske integracije izbjeglica i tražitelja međunarodne zaštite u hrvatsko društvo. Istraživanje se temelji na etnološkoj i kulturnoantropološkoj kvalitativnoj metodologiji: na intervjuima s azilantima i tražiteljima azila, sudjelovanju s promatranjem na radionicama kuhanja i promocijama hrane, te analizi medijskog diskursa. Osim integracijskog procesa koji se pokazao iznimno bitnim za azilante i tražitelje azila, autorice pokazuju koliko participacija odnosno pripremanje hrane u Okusu doma izbjeglicama omogućuje bivanje u transnacionalnom polju. Na kraju upućuju na dva sasvim suprotna načina prihvaćanja hrvatskih građana azilanata uključenih u ovu inicijativu (od dobrodošlice do distancije), drugih azilanata, tražitelja zaštite i, općenito, imigranata u Hrvatskoj.The integration of immigrants in the EU member states is one of the key social issues today. The aim of this paper is to, on the example of the Taste of Home collective case study, provide an overview of the attempts at the socio-economic, cultural and interactive integration of refugees and seekers of international protection into Croatian society and the extent to which they succeed at this. The research is based on ethnological and cultural-anthropological qualitative methodology: on interviews with asylees and asylum seekers, on the observation of participants in cooking workshops and food presentations and on media discourse analysis. In addition to the integration process, which is of exceptional importance for asylees and asylum seekers, the authors describe the extent to which participation, i.e. the preparation of food as part of the Taste of Home project, enables refugees to exist in a transnational field. Finally, they indicate the two diametrically opposed ways in which Croatian citizens accept asylees involved in this initiative (from friendliness to distance), other asylees, protection seekers and refugees in Croatia in general

    The matter of role and influence of the United Nations in resolution of international conflicts is decisive because they demonstrate their legal presence at the national as well as international level. Throughout the paper, the authors insist on determination of resolution of international conflicts pursuant to Chapter VII of the Charter of the United Nations. The basic hypothesis of the paper has been established on the premise by studying relevant provisions of 1945 Charter of the United Nations, 1949 Geneva Conventions and two additional protocols of 1977, United Nations resolutions, international treaties and international customary rules of war, it is possible to accurately determine the role, character and significance of the United Nations Security Council and the United Nations General Assembly in resolution of international conflicts. Furthermore, it is of interest to note that decisive significance for confirmation of the hypothesis lies with the objective image of the United Nations presented through mechanisms of the international law for resolution of armed conflicts. Furthermore, throughout the entire paper, the authors present international conflict resolution instruments as well as applicable legal consequences of effective resolution of the same, and ultimately, in the concluding considerations, they confirm that actions regarding resolution of armed conflicts are current, essential and timely

    Get PDF
    This paper is based on qualitative interviews with Kosovar Albanians, goldsmiths (Catholics from Prizren) and bakers (Muslims from the Has region) who live in Zagreb. The interviewees are economic migrants and their descendants who, during the coexistence in Yugoslavia, came to the area of the Republic of Croatia, especially to the tourist towns on the Adriatic coast, in order to work. Seasonal migration usually turned into permanent relocations to the city of Zagreb. With the breakup of Yugoslavia, the migrants became members of a national minority in the Republic of Croatia. Using the ethnography of the particular, and basing the research on migration systems theories, the theories of social and cultural integration and the transnational theory, the aim of this paper is to explore their lived experiences as migrants. The paper shows the causes of the migration and remigration, the reasons and the intensity of the (non)transformation of seasonal into permanent migration, the process of learning the crafts and ethnic entrepreneurship. Researching their life in Zagreb, we were interested in their everyday life, the groups from which they choose their marital partner, the language they speak, their connections to the place they came from, their participation in migrant circles, and how they spend their free time

    Amilografsko ispitivanje brašna se često provodi u cilju predviđanja kvalitete proizvoda na bazi žitarica. Međutim, vrlo je malo istraživanja provedeno na već gotovim proizvodima. Zadatak ovog rada bio je istražiti utjecaj zamjene durum krupice s ječmenim brašnom u rasponu 0 50 %, pripremiti uzorke tjestenine koji su sušeni pri različitim temperaturnim režimima (50, 70 i 90 ˚C) te provesti amilografsko ispitivanje usitnjenih uzoraka sušene tjestenine i rezultate usporediti s onima dobivenim tradicionalnim metodama ispitivanja kao što su ispitivanje teksturalnog profila, određivanje postotka raskuhavanja, apsorpcije vode i koeficijenta povećanja volumena tijekom kuhanja tjestenine. Na osnovi rezultata istraživanja provedenih u ovom radu može se zaključiti da temperatura sušenja i udio ječmenog brašna imaju statistički značajan utjecaj na amilografske pokazatelje kvalitete tjestenine. Povećanje temperature sušenja tjestenine značajno smanjuje postotak raskuhavanja i koeficijenta povećanja volumena tijekom kuhanja dok dodatak ječmenog brašna povećava postotak raskuhavanja, a smanjuje apsorpciju vode i koeficijent povećanja volumena tjestenine. Temperatura sušenja tjestenine značajno utječe na teksturu tjestenine, dok dodatak ječmenog brašna nema statistički značajan utjecaj. Amilografski pokazatelji kvalitete tjestenine statistički značajno koreliraju sa svim teksturalnim svojstvima osim elastičnosti, kao i sa postotkom raskuhavanja tjestenine te se može zaključiti da se provođenjem ove vrste ispitivanja na uzorcima tjestenine može dobiti potpuniji uvid u kvalitetu gotovog proizvoda.Amylographic evaluation of flour is often carried out in order to predict the quality of cereal based products. However, very few studies have been conducted on the finished products. The aim of this study was to investigate the effect of replacing durum semolina with barley flour in the range 0 to 50%, prepare the pasta samples that were dried at different temperatures (50, 70 and 90 ° C), conduct amylographic testing of grounded samples of dried pasta and compare results with those obtained by traditional testing methods such as texture profile analyses, determination of cooking loss, water absorption and swelling index of pasta during cooking. Based on the results of research carried out in this paper it can be concluded that the drying temperature and the proportion of barley flour have a statistically significant impact on amylographic indicators of pasta quality. Increase of pasta drying temperature significantly reduces the cooking loss and swelling index of pasta during cooking and the addition of barley flour increases the cooking loss and reduces the water absorption and swelling index.The pasta drying temperature significantly affects the texture of the pasta, and the addition of barley flour has no significant effect. Amylographic indicators of pasta quality significantly correlated with all the textural characteristics (except elasticity), as well as with the pasta cooking loss. Therefore, it can be concluded that the implementation of these types of tests on pasta samples can provide a more complete insight into the quality of the finished product

    Samplings in the Bay Mali Ston were performed between January 2002 and January 2003 at station Usko, conducted either once a week or twice a month, with 5-L Niskin water sampler at 1 m depth intervals from the surface to 13 m. The investigations of the population of planktonic protists and small metazoans covered the major assemblages: taxopodids, non-loricate ciliates, tintinnids, rotatorians, copepod nauplii, calanoids, oithonids, oncaeids, harpacticoids, bivalve larvae and juvenile appendicularians. The diversity and abundance of all assemblages on an annual basis is primarily dependent on variations in the hydrographic conditions. During periods of low temperature and high salinity, oncaea copepodites and adults show very high abundance, and together with non-loricate ciliates, tintinnids and planktonic harpacticoids form the winterspring zooplanktonic community. During the warmer period in conditions of higher temperature and salinity the summer-autumn zooplanktonic communities comprise high abundances of post-naupliar calanoids and oithonids, juvenile appendicularians and summer tintinnids. From the abundance of planktonic protists and small metazoans it can be concluded that the Bay Mali Ston has mesooligotrophic characteristics. This paper discusses the importance of the bio-deposition of faecal material from the shellfish that are cultured in the Bay and the potential negative impact on the ecological balance resulting from any significant increased capacity in aquaculture.Uzorkovanja u Malostonskom zaljevu provedena su u razdoblju od siječnja 2002. do siječnja 2003. na postaji Usko, jednom tjedno ili dva puta mjesečno, s 5L Niskin crpcem u slojevima od 1 m od površine do 13 m dubine. Istraživale su se populacije planktonskih protista i malih metazoa, kao što su: taxopodidi, nelorikatnih cilijati, tintinidi, rotatorii, od kopepoda, nauplii, kalanoidi, oitonidi, onceidi, harpacticoidi, ličinke školjkaša i juvenilne apendikularije. Raznolikost i bogatstvo svih skupina na godišnjoj razini u prvom redu ovisi o varijabilnostima hidrografskih parametara. Tijekom razdoblja niskih temperatura i visokog saliniteta, onceidni kopepoditi i odrasli su vrlo brojni, a zajedno s nelorikatnim cilijatima, tintinidima i planktonskim harpaktikoidima čine zimsko-proljetnu zooplanktonsku zajednicu. Tijekom toplijeg razdoblja u uvjetima visokih temperatura i slanosti je ljetno-jesenska zooplanktonska zajednica, koju čine postnaupliarni kalanoidi i oitonidi, nedorasle apendikularije i ljetni tintinidi. Iz brojnosti planktonskih protista i malih metazoa može se zaključiti da je Malo Stonski zaljev mezo-oligotrofnih karakteristika. U radu se raspravlja o važnosti biodepozicije fekalnog materijala školjki koje se uzgajaju u zaljevu i o mogućem negativnom utjecaju na ekološku ravnotežu zbog mogućeg značajnog povećanje kapaciteta školjkaša u uzgoju

    In the paper we present the results of the study on young people’s attitudes towards lifelong learning. The study was conducted on a sample of 100 Croatian university students from various study programmes and 100 pupils of a secondary school from Opatija. The aims of the study were to gain an insight into the participants’ knowledge of and attitude towards lifelong learning, and to examine whether there are any differences between the pupils’ and the students’ opinions. Two questionnaires were used to collect data. One was presented to the pupils and the other to the students. The results show that the students know more about lifelong learning than pupils, and that most participants are interested in future learning. While more than half of the pupils did not consider lifelong learning to be necessary, the majority of students, on the other hand, saw it as important for their future. Recommendations and possible practical implications of the study are discussed in the final part.Članek predstavlja rezultate raziskave, ki je analizirala odnos mladih do vseživljenjskega učenja. Študija je bila izvedena na vzorcu 100 hrvaških univerzitetnih študentov različnih programov ter 100 dijakov srednje šole iz Opatije. Cilj študije je bil pridobiti vpogled v znanje o vseživljenjskem učenju in v odnos udeležencev do njega ter hkrati preveriti, ali pri tem obstajajo razlike med dijaki in študenti. Pri pridobivanju podatkov sta bila uporabljena dva vprašalnika, eden za dijake in drugi za študente. Rezultati so pokazali, da študenti o vseživljenjskem učenju vedo več kot dijaki ter da pri večini udeležencev obstaja zanimanje za nadaljevanje učenja v prihodnosti. Medtem ko več kot polovica dijakov vseživljenjskega učenja ne doživlja kot nujnega, je večina študentov prepričana, da je pomembno za njihovo prihodnost. V zaključku članka so podana priporočila in nakazani možni praktični nastavki raziskave
