Članak govori o crkvi Sv. Nikole u vali Dražanica ispred gradske luke u Zadru. O njoj svjedoči povijesni izvor iz 14. stoljeća i fotografija snimljena početkom 20. stoljeća. U arhivskome izvoru ...zapisanom 3. svibnja 1383. godine zabilježeno je da će majstor Marko pokojnoga Marka popraviti crkvu Sv. Nikole u Dražanici, ecclesiam s. Nicolai ad Drachssiniçam. Crkva je unekoliko starija, a nalazila se na ulazu u valu uza samo more. Snimljena je 1912. ili 1913. godine. Tada se još čuvala u prostoru, premda u ruševnome stanju. Odlike arhitekture upućuju na srednjovjekovno razdoblje. Ipak, nije poznato kada je izgrađena, kao ni kada je posve razorena.
The electric power system, as an integrated system for transmission, distribution and consumption of electricity, is one of the most complex technical and economic systems today. Customers affect on ...the voltage quality of power network, but the network also has an impact on customers. All disturbances in the network can disrupt operation of the network and affect on operation of the customers, as well as reduce the level of efficiency and operation life or even seriously damage network. Number of customers is increasing every day, as well as proportion of customers who generate disturbances in the network and, at the same time, are sensitive to them. These circumstances impose the need for frequent monitoring of the network, so the analysis of power quality is not unjustified cost but extremely important and profitable investment. The quality of electricity, as part of the overall quality supply of electricity customers in deregulated conditions of liberal electricity market becomes significant regulatory parameter for network operators and a significant contracting parameter on the electricity market. Network operators are obliged to establish a system of individual measurements and a system of permanent monitoring of power quality parameters to determine the state and improve the parameters to the standardized level. Technical parameters are determined by the recommendations made at the international level and may, but do not need, be legally binding. Maintaining a certain level of voltage quality at some point of the network is the responsibility of electricity distributor. This task distributor executes by limiting of negative effects of producer/customer to the network. Therefore, each electricity producer/customer is obliged to reduce own negative feedback effects (injection of higher harmonics, taking of reactive power, emissions of flickers and loads unbalances) to a prescribed, prearranged, limited values. There are many norms that describe the quality of electricity, but in Europe the best known is EN50160 (issued by CENLEC). This paper presents the approach to measuring the voltage quality at the point of electricity delivery from distributed source into distribution network from the aspect of limiting the negative feedback of distributed source on the voltage quality.

For decades, we have been told we live in the "information age"-a
time when disruptive technological advancement has reshaped the
categories and social uses of knowledge and when quantitative
...assessment is increasingly privileged. Such methodologies and
concepts of information are usually considered the provenance of
the natural and social sciences, which present them as politically
and philosophically neutral. Yet the humanities should and do play
an important role in interpreting and critiquing the historical,
cultural, and conceptual nature of information. This book is one of
two companion volumes that explore theories and histories of
information from a humanistic perspective. They consider
information as a long-standing feature of social, cultural, and
conceptual management, a matter of social practice, and a
fundamental challenge for the humanities today. Bringing together
essays by prominent critics, Information: Keywords
highlights the humanistic nature of information practices and
concepts by thinking through key terms. It describes and
anticipates directions for how the humanities can contribute to our
understanding of information from a range of theoretical,
historical, and global perspectives. Together with Information:
A Reader , it sets forth a major humanistic vision of the
concept of information.
The book provides graduate students and researchers with an up-to-date survey of statistical and econometric techniques for the analysis of count data, with a focus on conditional distribution ...models. Proper count data probability models allow for rich inferences, both with respect to the stochastic count process that generated the data, and with respect to predicting the distribution of outcomes. The book starts with a presentation of the benchmark Poisson regression model. Alternative models address unobserved heterogeneity, state dependence, selectivity, endogeneity, underreporting, and clustered sampling. Testing and estimation is discussed from frequentist and Bayesian perspectives. Finally, applications are reviewed in fields such as economics, marketing, sociology, demography, and health sciences. The fifth edition contains several new topics, including copula functions, Poisson regression for non-counts, additional semi-parametric methods, and discrete factor models. Other sections have been reorganized, rewritten, and extended.
Selen je važan mikroelement u prehrani ljudi i hranidbi životinja. Cilj ovoga rada je prikazati metode/postupke koji se poduzimaju u procesu obogaćivanja janjećeg mesa selenom. Različitim hranidbenim ...modifikacijama moguće je značajno promijeniti (prije svega poboljšati) sadržaj minerala u janjećem mesu pa tako i selena. Unos selena u janjadi varira zbog promjene elementarnog sastava biljnih vrsta tijekom sezone, te koncentracije u krmnoj smjesi. Hranidbeni čimbenici imaju značajan utjecaj na sadržaj selena u janjećem mesu. Selen organskog podrijetla, osobito podrijetlom od biofortificiranih krmiva pokazuje bolju dostupnost u odnosu na anorganski izvor a korišteni su za poboljšanje zdravlja i proizvodnosti te mogu biti put u procesu obogaćivanja janjećeg mesa selenom prirodnim putem. Analizom dosadašnjih dostupnih istraživanja vidljiv je značajan utjecaj dodatka selena (organski oblici) ili korištenih biofortificiranih krmiva selenom u hrani janjadi na njegov sadržaj u janjećem mesu te je to put koji treba koristiti u procesu obogaćivanja janjećeg mesa selenom
Selenium is an important trace element in human and animal nutrition. The aim of this research is to present the methods/procedures that are undertaken in the process of enrichment of lamb meat with selenium. Various nutritional modifications can significantly change (primarily improve) the mineral content in lamb meat and thus selenium. Selenium intake in lambs varies due to changes in the elemental composition of plant species during the season, and the concentration in the feed mixture. Nutritional factors have a significant impact on the selenium content in lamb meat. Selenium of organic origin, especially originating
from biofortified feeds, shows better availability compared to the inorganic source and it has been used to improve health and productivity
as well as be a way in the process of enriching lamb meat with selenium
naturally. The analysis of previous research shows a significant impact
of selenium supplementation (organic forms) or used biofortified feeds with selenium in lamb feed on its content in lamb meat and this is the way to be used in the process of enriching lamb meat with selenium.
Predmet ovog rada jeste manipulativna strategija ograđivanja kojom se novinar služi u novinskim izvještajima na srpskom i njemačkom jeziku kako bi iskazao svoj nedostatak opredijeljenosti prema ...istinitosti propozitivnog sadržaja. Ovakav vid distanciranja od propozitivnog sadržaja u lingvističkoj literaturi svrstava se u domen modalnosti, i to indirektne epistemičke modalnosti. U ovom radu ćemo kontrastivnom metodom ukazati na spektar jezičkih sredstava karakterističnih za ovaj vid modifikovanja iskaza u svjetlu činjenice da govorno lice nije izvor informacije, pri čemu ćemo istovremeno istaći sličnosti i razlike u pomenutim jezicima.
Pozadina istraživanja. U posljednje se vrijeme istražuju novi izvori dokosaheksaenoične kiseline koji se mogu upotrijebiti za obogaćivanje hrane za dojenčad i dodatke prehrani, među ostalim i ...mikrobni lipidi što sadržavaju 40-50 % te kiseline. Eksperimentalni pristup. U tu su svrhu mikrobni lipidi pomiješani s kaprilnom kiselinom u molarnom omjeru od 1:1 do 5:1, a zatim su smjese interesterificirane pomoću katalizatora, lipaze Novozym 435 ili Lipozyme TL IM. Ispitan je utjecaj suviška slobodne kaprilne kiseline u supstratu i vrste enzima na promjenu strukture triglicerida tijekom sinteze strukturiranih lipida. Rezultati i zaključci. Regiospecifična lipaza Lipozyme TL IM izgleda potiče transesterifikaciju triglicerida u mikrobnim lipidima kaprilnom kiselinom, proporcionalno udjelu te kiseline u supstratu. U reakcijama kataliziranim nespecifičnom lipazom Novozym 435 u trigliceride mikrobnih lipida ugrađeno je više kaprilne kiseline nego pri uporabi lipaze Lipozyme TL IM, neovisno o molarnom omjeru lipida i kaprilne kiseline. Novina i znanstveni doprinos. Dobiveni rezultati pokazuju da je za proizvodnju strukturiranih lipida kao izvora dokosaheksanoične kiseline bitno odabrati pravu kombinaciju regiospecifične ili nespecifične lipaze i udjela slobodnih masnih kiselina u podlozi za kiselinsku hidrolizu.
The application of probability and statistics to an ever-widening number of life-decisions serves to reproduce, reinforce, and widen disparities in the quality of life that different groups of people ...can enjoy. As a critical technology assessment, the ways in which bad luck early in life increase the probability that hardship and loss will accumulate across the life course are illustrated. Analysis shows the ways in which individual decisions, informed by statistical models, shape the opportunities people face in both market and non-market environments. Ultimately, this book challenges the actuarial logic and instrumental rationalism that drives public policy and emphasizes the role that the mass media play in justifying its expanded use. Although its arguments and examples take as their primary emphasis the ways in which these decision systems affect the life chances of African-Americans, the findings are also applicable to a broad range of groups burdened by discrimination.
This study of the upper Maastrichtian to Danian sedimentary succession from the northern part of the Romanian Eastern Carpathians (Varniţa section) aims to establish an integrated biostratigraphy ...based on calcareous nannofossils, organic-walled dinoflagellate cysts (dinocysts) and foraminiferal assemblages, and to reconstruct the depositional environments of the interval. The stratigraphic record across the studied section is incomplete, considering that an approximately 16 m thick strata interval from the top of the Maastrichtian to lowermost Danian cannot be analyzed due to a landslide covering the outcrop. The upper Maastrichtian is marked by a succession of biostratigraphic events, such as the First Appearance Datum (FAD) of the nannoplankton taxon Nephrolithus frequens and FAD of the dinocyst species Deflandrea galeata and Disphaerogena carposphaeropsis, and the Last Appearance Datum (LAD) of Isabelidinium cooksoniae in the lower part of the section. These bioevents are followed by the LAD of the Dinogymnium spp. and Palynodinium grallator dinocyst markers in the top of the Maastrichtian deposits analyzed. In terms of foraminiferal biostratigraphy, the upper Maastrichtian Abathomphalus mayaroensis Zone is documented in the lower part of the studied section. Some bioevents, such as the bloom of the calcareous dinoflagellate genus Thoracosphaera and the FAD of the organic-walled dinocysts Damassadinium californicum, Senoniasphaera inornata, Xenicodinium lubricum and X. reticulatum suggest an early Danian age for the middle part of the section. From the Danian deposits in the Varniţa section, we describe a new organic-walled dinocyst species, Pentadinium darmirae sp. nov., which is until now the only species of the Pentadinium genus discovered in the Paleocene. The occurrence of the global Danian dinocyst marker Senoniasphaera inornata in the top of the section, suggests an age not younger than middle Danian (62.6 Ma) for the analyzed deposits.
The palynofacies constituents, as well as the agglutinated foraminiferal morphogroups, used to reconstruct the depositional environments, show that the late Maastrichtian sediments were deposited in an outer shelf to distal (bathyal) environment, followed by a marine transgression during the Danian.
•Microfossils of the K–Pg sedimentary succession, Eastern Carpathians, are studied.•A new dinoflagellate cyst species was identified.•Paleoenvironmental conditions based on palynofacies and microfossils are discussed.
U radu se analizira stanje i kvaliteta okoliša kojeg ugrožavaju postojeći tipični zagađivači urbanih predjela. Glavni izvori zagađenja zraka su sektor energije (uglavnom energane), transporta ...(motorna vozila) i industrijski pogoni. Među najčešćim i najškodljivijim za ljudsko zdravlje i biološke sustave je sumporni dioksid. Djelovanje sumpornog dioksida osjeća se vrlo lako i većina ljudi osjeća simptome već nakon 10÷15 minuta. Stoga se koncentracija ugljičnog dioksida u zraku uzima kao referentni parameter u procjeni kvalitete zraka i njegovog zagađenja. U radu se kao ilustrativni primjer analizira metalurški pogon koji dnevno prerađuje 1000 tona rude bakra-halkopirita. Primjenom Gausova matematičkog modela analizira se raspodjela koncentracije sumpornog dioksida na zemlji kod dimnjaka raznih visina i različitih količina ispuštanja u stabilnim i nestabilnim vremenskim uvjetima. Distribucija i širenje sumpornog dioksida izračunati su za razdoblje od 24 sata nakon ispuštanja u atmosferu. Rezultati su uspoređeni s legalno dopuštenim koncentracijama graničnih vrijednosti.
