Abstract  

The reaction of [TcNCl2(PPh3)2] with 2,2′:6′,2″-terpyridine producedcis-[TcNCl2(terpy)] selectively. The resulting complexes were characterized by1H NMR and IR spectroscopy. The geometries of thecis andtrans isomers were estimated by theoretical calculations following a density functional method. Thecis isomer is likely more stable than thetrans one with respect to thetrans influence of the nitrido ligand. Furthermore, the behavior of nitridotechnetium complexes in polar solvents was compared to Os-analogues.

Abstract  

In order to obtain a better understanding of the pyrolysis mechanism of urazole, molecular orbital (MO) calculations and evolved gas analysis were carried out. The MO calculations were performed using the density functional method (B3LYP) at the 6-311++G(d,p) levels by Gaussian 03. The geometrical structure of urazole and its tautomers were examined theoretically. Identification and real-time analysis of the gases evolved from urazole were carried out with thermogravimetry-infrared spectroscopy (TG-IR) and thermogravimetry-mass spectrometry (TG-MS). The evolved gases were identified as HNCO, N2, NH3, CO2, and N2O at 400 °C, but were different at other temperatures.

Abstract  

The aim of the present work was the characterization of nonpregnant and early pregnant myometrium (days 3–6) of the rat by means of differential scanning calorimetry (DSC). The spontaneous motor activity as well as the KCl-evoked contractions of isolated uterine rings was additionally recorded. A relatively close correlation was found between calorimetric enthalpy (ΔH) and the contractility of the uterus samples. Our results indicate that DSC is a useful tool for the investigation of the functions of developing myometrium and it can be considered as supplementing the traditional structural and functional methods.

Using the classical and functional methods of growth analysis, the effect of mineral N fertiliser (0, 80, 160 and 240 kg ha −1 ) on the dynamics of growth and growth parameters was studied in 2001 and 2002 in a two-factorial, long-term experiment set up in a split-plot design on three maize hybrids with different genotypes, Mv 272 (FAO 280), Mv 355 (FAO 390) and Maraton (FAO 450). The following growth parameters were calculated to characterise the effect of N fertiliser: the absolute growth rate (AGR, ALGR), the relative growth rate (RGR), the leaf area index (LAI), the net assimilation rate (NAR) and the harvest index (HI).Similar tendencies were found for the yield response of maize and the values of the growth parameters as a function of N fertilisation. Based on the results of principal component analysis, multiple regression analysis and discriminant analysis, the parameters AGR, LAI max , ALGR and HI were found to have a decisive influence on the grain yield of maize. It could be concluded from the results that growth parameters can be used to predict the N fertiliser responses of maize in early growth stages.

Összefoglalás

A termést meghatározó növekedésdinamika egyrészről genetikailag meghatározott tulajdonság, másrészről pedig környezeti adottságoktól függ. A környezeti tényezők közül a N-műtrágyázásra (0, 80, 160 és 240 kg/ha) adott növekedési- és produkcióbeli reakciókat vizsgáltuk három eltérő tenyészidejű genotípus (extra korai Mv Toborzó, korai Mv Palotás és középkorai Mv Verbunkos) esetében 2007-ben és 2008-ban. A kísérletet Martonvásáron, erdőmaradványos csernozjom talajon állítottuk be. A növekedésanalízishez hetente vettünk mintát, 2007-ben összesen 24, 2008-ban 21 alkalommal. A szárazanyag és levélterület dinamikájával, és az ezekből számított növekedési mutatókkal jellemeztük a N-műtrágyázás, a fajták, illetve az évjárat hatását. A növekedésanalízis klasszikus és funkcionális módszerével kiszámítottuk a levélterület index (LAI), a biomassza- és levélterület tartósság (LAD, BMD), valamint harvest index (HI) mutatókat. Megállapítottuk, hogy a szárazanyag produkció és a levélterület az N160, ill. az N240 kezelésig szignifikáns növekedést mutatott. A maximális LAI, a kumulált LADLAI és BMD, valamint HI mutatók kvantitatív értékekkel jellemezték a N-műtrágyázás, a genotípus és az évjáratok hatását. A legnagyobb termést 2007-ben az N160, 2008-ban az N80 műtrágyaszinten kaptuk, a növekedési mutatók legmagasabb értékeit pedig mindkét évben az N160 és N240 kezelésekben.
