    The aim of the study was to examine the impact of microbiological and organic fertilizers on morphological and productive characteristics of triticale during a three-year period (2009/10ā€“2011/12). A two-factorial field experiment was arranged using a randomized block design with four replications. The object of the study was the triticale winter cultivar Odisej, and the following treatments were applied: a control variant without fertilization, microbiological fertilizer ā€œSlavolā€ (Agrounik Serbia) 5.0 l ha-1, organic fertilizer ā€œBiohumus Royal offertā€ (Altamed RS) 3.0 t ha-1 + microbiological fertilizer ā€œSlavolā€ (Agrounik Serbia) 5.0 l ha-1. The results showed that the expression of the characteristics was significantly affected by the environment. The lowest values were obtained in the first year when the most unfavourable meteorological conditions were observed. The application of microbiological fertilizer had no impact on the stem length and grain weight per spike, but it significantly increased the number of fertile spikelets (3.7%), spike length (7.7%) and grain yield (18.6%). The combined application of fertilizers provided better results for all the examined characteristics, while in comparison with the control, the differences ranged from 4.3% for the number of fertile spikelets to 46.5% for grain yield. The strongest correlation was determined between the spike length and the number of fertile spikelets (r = 0.939**). The obtained results lead to the conclusion that under variable environmental conditions, the application of fertilizers has a significant impact on morphological and productive characteristics of triticale, and consequently on the stability of this crop production in the organic farming system.Cilj istraživanja bio je ispitivanje uticaja biohumusa i biofertilizatora na morfoloÅ”ke i produktivne osobine tritikalea u trogodiÅ”njem periodu (2009/102011/12). Poljski ogled je postavljen kao dvofaktorijalni, po metodi blok sistema sa slučajnim rasporedom tretmana u četiri ponavljanja. Predmet ispitivanja bila je ozima sorta tritikalea, Odisej, a ispitivan je uticaj sledećih tretmana: kontrola bez đubrenja, biofertilizator (5,0 l ha-1), biohumus (3,0 t ha-1) + biofertilizator (5,0 l ha-1). Rezultati su pokazali da spoljaÅ”nja sredina ima značajan uticaj na ekspresiju ispitivanih osobina. Najmanje vrednosti dobijene su u prvoj godini, koja je imala i najnepovoljnije meteoroloÅ”ke uslove. Đubrenje je imalo statistički značajan uticaj na većinu ispitivanih osobina. Primena biofertilizatora nije uticala na dužinu stabla i masu zrna u klasu, ali je značajno povećala broj plodnih klasića (3,7%), dužinu klasa (7,7%) i prinos zrna (18,6%). Kombinovanom primenom đubriva postignuti su bolji rezultati za sve ispitivane osobine, a razlike u odnosu na kontrolu bez đubrenja kretale su se u nivou od 4,3% za broj plodnih klasića do 46,5% kod prinosa zrna. Najjača korelaciona povezanost ustanovljena je između dužine klasa i broja plodnih klasića (r = 0,939**). Dobijeni rezultati upućuju na zaključak da, u promenljivim uslovima spoljaÅ”nje sredine, primena dobro izbalansiranih formula organskih i mikrobioloÅ”kih đubriva ima značajan uticaj na morfoloÅ”ke i produktivne osobine tritikalea, a samim tim na stabilnost proizvodnje ovog useva u sistemu organskog gajenja

    In this investigation used three maize hybrids that are belongs to different group of ripening: FAO 3, FAO 4 and FAO 6. The seed of those hybrids used for investigation of genotypic divergences for seed germination, energy of germination, content of abnormal emergence of seeds, content of dead seeds. Hybrid seed for analysis produced on the experimental field of the Institute of Maize in Zemun Polje, Belgrade. The viability of the maize hybrids seeds were determined in experimental analysis carried out in laboratory for quality of seed in the Maize Research Institute Zemun Polje, Belgrade. According to standard method on filter paper were estimated the values of seed germination. The three experiment of seed germination carried out: 2 months after harvest, 9 months after harvest and 18 months after harvest. In average for each test the highest percentage of seed germination were found for hybrid ZP FAO3: 92.75% for seed after 2 months of harvest, 92.00% for seed 9 monhts after harvest and 91.50% for seeds after 18 months of harvest. This hybrid had the lowest percentage of ungerminated seeds (2.75%) and the least content of dead seed (~5.00%). The lowest value of seed germination (86.33%) and the highest values of ungerminated seed (~3.00%) as well the highest content of dead seed (10.33%) had hybrid belongs FAO 4 group. The obtained results indicate differences of germination in analyzed maize genotypes

    There are many determinants of vancomycin clearance, but these have not been analyzed separately in populations with different levels of renal function, which could be why some important factors have been missed. The aim of our study was to compare the pharmacokinetic parameters and factors that may affect vancomycin pharmacokinetics in groups of patients with normal renal function and in those with chronic kidney failure. The study used a population pharmacokinetic modeling approach, based on plasma vancomycin concentrations and other data from 78 patients with chronic kidney failure and 32 patients with normal renal function. The model was developed using NONMEM software and validated by bootstrapping. The final model for patients with impaired kidney function was described by the following equation: CL (L/h) = 0.284 + 0.000596 x DD + 0.00194 x AST, and that for the patients with normal kidney function by: CL (L/h) = 0.0727 + 0.205 x FIB. If our results are confirmed by new studies on two similar populations, these factors could be considered when dosing vancomycin in patients with chronically damaged kidneys, as well as in patients with normal kidneys who frequently require high doses of vancomycin

    Integrated Reconfigurable Silicon Photonics Switch Matrix in IRIS Project: Technological Achievements and Experimental Results

    This paper reports the performances of a silicon photonics optical switch matrix fabricated by using large scale 3D integration. The wavelength selective optical switch consists of a photonic integrated circuit (PIC), with 1398 circuit elements, interconnected in a 3D stack with its control electronic integrated circuit (EIC). Each PIC element can be trimmed or reconfigured by using metallic heaters. The EIC is designed to drive the heaters and to read the signal of monitor photodiodes integrated into the PIC. Small footprint and high energy efficiency are achieved in the PIC and the EIC. Automatic wavelength alignment of the optical circuits in the PIC to the ITU grid and fine temperature tuning of each photonic element to optimize the switch insertion losses are obtained by an optimization routine. A fully packaged switch with input/output fibers is tested both for optical and electrical characteristics as well as for the system performances. Fiber to fiber insertion losses of about 20 dB and channel isolation of -35 dB are achieved. BER characteristics at 25 Gbps are evaluated. Perspective applications of the optical switch in optical transport and intra-data center networks are discussed

    An electronic integrated circuit (EIC) and a silicon photonic integrated circuit (PIC) are three-dimensional (3D)- integrated. The EIC using the complementary metal-oxide-semiconductor (CMOS) part of STMicroelectronicsā€™ BCD8sp 0.16Ī¼m technology controls all 768 switches in the PIC individually and monitors them with 84 transimpedance amplifiers (TIAs). A scalable analog-digital approach with a cell size of 100Ɨ100Ī¼mĀ² for thermal control of optical ring resonator switch matrices is introduced. An electrical power consumption of 220mW for all electronic control circuits of the optical swi tch matrix is resulting in 5.5% of the power needed by a constant-voltage control approach
