Comparison of technical characteristics between tractors with semi-trailers and forwarders with load capacity up to 10 tonnes
Drvo u prorednim sjeÄinama nizinskih Å”uma, izvozi se prvenstveno traktorskim skupovima (poljoprivredni traktor sa Å”umskom prikolicom i dizalicom). Uslijed sve veÄe potražnje za energetskim drvom dolazi do razvoja forvardera manjih dimenzija, nosivosti, mase. Na temelju izabranih geometrijskih, masenih i drugih veliÄina usporeÄuje se pogodnost traktorskih skupova i forvardera nosivosti do 10 tona za izvoženje drva iz prorednih sastojina
Trace Elements in the Soil Samples of Medvednica mountain - Extraction by Water solutions of Ammonium Chloride and Ammonium NItrate and Determination by ICP-AES
U ovom radu napravljena je ekstrakcija metala i
polumetala iz uzoraka tla s Medvednice, blagim
ekstrakcijskim sredstvima. Ekstrakcija je raÄena vodenim
otopinama amonijeva klorida NH4Cl i amonijeva nitrata
NH4NO3. Kontrola analitiÄkog postupka provoÄena je
pomoÄu certificiranog referentnog materijala
METRANALĀ® 33. Koncentracije traženih metala i
metaloida u tako prireÄenim otopinama odreÄene su
tehnikom ICP-AES. Dobiveni rezultati statistiÄki su
obraÄeni

RužiÄka days : International conference 19th RužiÄka Days āToday Science ā Tomorrow Industryā : Proceedings
Dear colleagues, we are extremely honoured to present to you the Proceedings of the international conference 19th RužiÄka Days, which was successfully held on September 21ā23, 2022, in Vukovar, Croatia, in the hometown town of our famous Croatian scientist and first Nobel laureate, professor Leopold (Lavoslav) RužiÄka. The main goals of the Conference were to promote excellence, originality and innovation of interdisciplinary scientific research as well as the practical application of the obtained results through collaboration with industry, emphasizing thus the recognizable slogan of the RužiÄka Days conference: "Today Science ā Tomorrow Industry". In addition, the Conference gave the opportunity for meetings, exchanging the ideas, opinions, experiences and cooperation among participants from different working surroundings. It is also important to point out that since 2008, within the international conference RužiÄka Days, Meeting of Young Chemists has also been held, where high school students, with the help of their mentors, present papers in the field of chemistry, with the aim to direct students and young people to the technical and natural sciences, especially chemistry. In its seventh issue (2011, 2013, 2015, 2017, 2019, 2021) the Proceedings publishes scientific and professional full papers of high quality in the following sections: Chemical analysis and synthesis (10), Chemical and biochemical engineering (3), Food technology and biotechnology (4), Chemistry in agriculture and forestry (1), Environmental protection (9) and 8th Meeting of Young Chemists (3). Full-length papers were subjected to an international review procedure done by eminent experts from the corresponding fields, to whom we express our gratitude, but they were not subjected to linguistic proofreading. On behalf of the Scientific and Organizing Committee of the 19th RužiÄka Days we cordially thank all the authors, reviewers, participants, lecturers, organizers, especially the international organizers EuCheMS and EHEDG, auspices and sponsors, and all the others who, in any way, supported the Conference and contributed to the preparation of the Proceedings, especially to our highly skilled and committed associates, who have put a lot of effort in the preparation of these Proceedings. At the very end, special thanks to our young, future scientists and their mentors who are faithful participants of the Meeting of Young Chemists of the RužiÄka Days conference. Enjoy the extremely interesting scientific and professional papers contained in these Proceedings, until the next 20th jubilee of RužiÄka Days in 2024! We are looking forward to meeting you again in Vukovar! Yours sincerely, Chief Editors Jurislav BabiÄ Vesna OceliÄ BulatoviÄ Dajana KuÄiÄ Grgi
