Noviji rezultati oplemenjivanja voćaka u Institutu za voćarstvo, Čačak

The Fruit Research Institute Čačak has seventy years long tradition in breeding of continental fruit species. The continual multi-disciplinary scientific and research work conducted so far has resulted in the releasing of 41 different cultivars. In addition to the named and released cultivars, for promising candidate cultivars have been selected (three plums and one peach) and entered for releasing, while there is also a large number of promising genotypes that are currently under intense evaluation. The paper presents an overview of the most significant biological and productive characteristic of the 12 new cultivars of pome and stone fruits, including seven plum cultivars (Boranka, Timočanka, Zlatka, Nada, Mildora, Krina and Pozna plava), two pear cultivars (Julijana and Anđelija) and three sour cherry cultivars (Sofija, Nevena and Iskra).Institut za voćarstvo, Čačak ima sedamdeset godina dugu tradiciju oplemenjivačkog rada na stvaranju novih sorti kontinentalnih vrsta voćaka. Do sada je kao rezultat kontinuiranog, multidisciplinarnog naučnoistraživačkog rada priznata 41 sorta različitih vrsta voćaka. Pored priznatih sorti, izdvojene su četiri kandidat sorte (tri šljive i jedna breskve) koje su u postupku priznavanja, kao i veliki broj perspektivnih genotipova koji se intenzivno proučavaju. U radu je prikazan pregled najznačajnijih bioloških i proizvodnih osobina 12 novije priznatih sorti jabučastih i koštičavih vrsta voćaka, i to: sedam sorti šljive (Boranka, Timočanka, Zlatka, Nada, Mildora, Krina i Pozna plava), dve sorte kruške (Julijana i Anđelija) i tri sorte višnje (Sofija, Nevena i Iskra)

Formation of Proton Translocating Water Channels in ATP Synthase

The F1FO – ATP synthase has been the object of study in the scientific community both from theory and experiment over the past couple of decades. The ATP synthase is a protein complex in the mitochondrial membrane that efficiently converts the cell’s transmembrane proton gradient into chemical energy stored as adenosine triphosphate (ATP). The protein is made of two molecular motors, F1 and FO, coupled by the central stalk. The free energy used for the synthesis of ATP is in the form of protons moving down the electrochemical gradient from the inner-membrane space to the mitochondrial matrix via the two offset half-channels. The membrane bound part of ATP synthase, FO, converts the transmembrane electrochemical potential into mechanical rotation of the rotor in FO and the stalk physically connected to it. Mutations in a gene encoding ATP synthase are proven to affect its function and cause severe syndromes related to energy deficiency. In this dissertation, we study, using molecular dynamics (MD) simulations, the formation of the half-channels within the stator part of FO. These half-channels enable the proton translocation to and from the rotor portion, known as the c-ring. Combining MD with the protein structure network paths and hydrogen-bonding network analysis, we were able to observe clear evidence for proton pathways and compare our results with previous experimental results. We also report studies of leucine-arginine and leucine-proline amino acid replacements, encoded by the T-G and T-C point mutations at locus 8993 of mtDNA. Our results suggest, for the first time, that these mutations adversely affect water half-channels, and consequently impair the ability of the ATP synthase to produce ATP.Physics, Department o

Economics of Digital Transformation

The papers published in this monograph present best papers presented at the first conference of the Faculty of Economics and Bussiness of University of Rijeka organized on the topic of “Economics of digital transformation” from 2nd to 4th of May, 2018 in Opatija, Croatia (www.edt- conference.com). During the three days of the conference more than 50 researchers from European region contributed with their presentations. We are particularly proud on the results of our doctoral workshop where nine young researchers presented their research while five papers were published in the monograph. In this way we are building our future research capacities and expose young researchers to rigorous scientific challenge
