Vučedol-Streimov vinograd: magijski ritual i dvojni grob vučedolske kulture

Dvojni grob 3 (V-87) na Vučedolu – Streimov vinograd bio je pokriven naopako okrenutom golemom posudom. Usporedba s drugim prethistorijskim nalazima, kao i s podacima iz sredozemnih civilizacija, pokazuje da se radilo o magijskom ritualu – vjerojatno o zaštiti od zlih sila ili duhova

Jedna posuda vučedolske kulture s posebnim obzirom na cjevaste vaze

1985. g. u istraživanjima Vučedola (Streimov vinograd) nađen je fragment cilindrične posude. Uspoređujući je s poznatim primjercima iz prethistorije, minojske Krete, civilizacija Bliskog Istoka, kao i iz vremena klasične Grčke, zaključujemo da je i naša mogla imati sličnu funkciju – da je služila za libacije, vjerojatno htoničkim božanstvima

Novi nalazi konsekrativnih rogova na Vučedolu

Na lokalitetu Vučedol-Streimov vinograd, u istraživanjima od 1984. do 1989. godine, nađena su dva čitava sedlasta žrtvenika (konsekrativni rogovi) od kojih se jedan mogao potpuno rekonstruirati. Ti kultni predmeti poznati su i sa drugih nalazišta vučedolske kulture, kao i među nalazima ostalih kultura evropske prethistorije. Njihov se razvojni put može pratiti od ranog neolitika Bliskog Istoka, pa do brončanog doba kada su bili rašireni gotovo cijelim starim svijetom. Njihovo se kultno značenje, izgleda, pri tom nije bitno mijenjalo

Sisak u antičkim izvorima

U svijet Rima Siscija ulazi u 2. st. pr. Kr. Nakon što je nekoliko puta opsijedana osvaja je Oktavijan 35. g. pr. Kr. Od tada je Siscija rimski grad. Kao važna strateška točka igrala je presudnu ulogu u ustanku dvaju Batona 6-9- g. Tu je Tiberije smjestio najveću vojnu silu Rima u to vrijeme. Vespazijan grad uzdiže na rang kolonije, vjerojatno 71. g.: COLONIA FLAVIA SISCIA stoji na natpisima. Za cara Hadrijana grad doživljava veliki procvat, a od cara Septimija Severa dobiva titulu Colonia Siscia Septimia Augusta 194. g. Za vrijeme cara Galijena u Sisciji je otvorena kovnica novca. Kad je Dioklecijan reforirao državu i nanovo podijelio Panoniju, Siscija postaje centar provincije Savije s kovnicom i riznicom provincije. Grad igra ulogu u ratu Konstantina i Licinija 314. g., zatim u vrijeme borbi Konstancija II. s uzurpatorom Magnencijem 351. g. 388. g. kod Siscije su se sukobili car Teodozije i uzurpator Maksim. U vrijeme Valentijana III. Savija je otvorena Hunima za naseljavanje, a nakon propasti hunske države dolaze Ostrogoti, pa je Siscija dio Teodorikove države. S provalom Avara i Slavena nema više spomena Siscije kao antičkog grada

"A Girls Picking Flowers" from Stabiae

Famous picture depicting a girl picking frowers from Stabiae has been an object of discussion for years. She is probably copy of an original dating c. 330. BC and represents Persephone picking flowers immediately before Pluto abducted her

Generalized autoregressive conditional correlation

This paper develops a generalized autoregressive conditional correlation (GARCC) model when the standardized residuals follow a random coefficient vector autoregressive process. As a multivariate generalization of the Tsay (1987, Journal of the American Statistical Association 82, 590-604) random coefficient autoregressive (RCA) model, the GARCC model provides a motivation for the conditional correlations to be time varying. GARCC is also more general than the Engle (2002, Journal of Business & Economic Statistics 20, 339-350) dynamic conditional correlation (DCC) and the Tse and Tsui (2002, Journal of Business & Economic Statistics 20, 351-362) varying conditional correlation (VCC) models and does not impose unduly restrictive conditions on the parameters of the DCC model. The structural properties of the GARCC model, specifically, the analytical forms of the regularity conditions, are derived, and the asymptotic theory is established. The Baba, Engle, Kraft, and Kroner (BEKK) model of Engle and Kroner (1995, Econometric Theory 11, 122-150) is demonstrated to be a special case of a multivariate RCA process. A likelihood ratio test is proposed for several special cases of GARCC. The empirical usefulness of GARCC and the practicality of the likelihood ratio test are demonstrated for the daily returns of the Standard and Poor's 500, Nikkei, and Hang Seng indexes

Pharmacy student perceptions of pharmacist prescribing: A comparison study

Several jurisdictions throughout the world, such as the UK and Canada, now have independent prescribing by pharmacists. In some areas of Canada, initial access prescribing can be done by pharmacists. In contrast, Australian pharmacists have no ability to prescribe either in a supplementary or independent model. Considerable research has been completed regarding attitudes towards pharmacist prescribing from the perspective of health care professionals, however currently no literature exists regarding pharmacy student views on prescribing. The primary objective of this study is to examine pharmacy student’s opinions and attitudes towards pharmacist prescribing in two different settings. Focus groups were conducted with selected students from two universities (one in Canada and one in Australia). Content analysis was conducted. Four main themes were identified: benefits, fears, needs and pharmacist roles. Students from the Australian University were more accepting of the role of supplementary prescribing. In contrast, the Canadian students felt that independent prescribing was moving the profession in the right direction. There were a number of similarities with the two groups with regards to benefits and fears. Although the two cohorts differed in terms of their beliefs on many aspects of prescribing, there were similarities in terms of fears of physician backlash and blurring of professional roles

Sustainable mechanochemical synthesis of β-cyclodextrin polymers by twin screw extrusion

Cyclodextrin nanosponges (CD-NS) are cross-linked cyclodextrin polymers characterized by a nanostructured three-dimensional network. CD-NSs in the last years found many different applications in the pharmaceutical field for the controlled release of drugs and for the absorption of undesired substances from physiological media, food, and wastewater. Most of CD-NS syntheses involve the solubilization of the chosen CD in closed batch, using a suitable organic polar aprotic liquid, which may affect potential environmental or biomedical applications. Since the research is now moving towards more sustainable approaches, new and greener syntheses of CD-NS are now being developed. Here, it is reported a new eco-friendly and efficient synthesis of nanosponges through mechanochemistry. Mechanochemistry involves the application of mechanical forces to drive and control chemical reactions by transferring energy to chemical bonds. The mechanochemical approach involves the use of a twin-screw extruder (TSE) as a chemical reactor: TSE are capable of fine temperature control and, furthermore, TS Extrusion is a continuous process and not a batch process. Among the many available CD-NS syntheses, we tested our solvent-free approach on a β-CD/citric acid (CA) system. Moreover, using TSE, the same polymer was obtained in a considerably shorter time. The so obtained NSs were used for the adsorption and removal of probe molecules, in comparison with NSs prepared by cross-linking β-CD with CA in batch.
