a complex of cu(ii) with 1-(6-hydroxynaphthalen-2-yl) butane-1,3-dione (hnbd) was synthesized and characterized by elemental analysis, ir, uv and dta-tg-dtg techniques.    ir spectra as well as uv-visible absorption measurements indicated that cu(ii) ion was coordinated to the hnbd ligand. the tg-dta-dtg curves showed that thermal decomposition of the anhydrous complex was a two-stage process a...

We use cell decomposition techniques to study additive reducts of p-adic fields. We consider a very general class of fields, including fields with infinite residue fields, which we study using a multi-sorted language. The results are used to obtain cell decomposition results for the case of finite residue fields. We do not require fields to be Henselian, and we allow them to be of any character...

Root carbon (C) inputs may regulate decomposition rates in soil, and in this study we ask: how do labile C inputs regulate decomposition of plant residues, and soil microbial communities? In a 14 d laboratory incubation, we added C compounds often found in root exudates in seven different concentrations (0, 0.7, 1.4, 3.6, 7.2, 14.4 and 21.7 mg C g(-1) soil) to soils amended with and without (13...

Physical protection of soil carbon (C) is one of the important components of C storage. However, its exact mechanisms are still not sufficiently lucid. The goal of this study was to explore the influence of soil structure, that is, soil pore spatial arrangements, with and without presence of plant residue on (i) decomposition of added plant residue, (ii) CO2 emission from soil, and (iii) struct...

MOTIVATION Automatic decomposition of a multi-domain protein into individual domains represents a highly interesting and unsolved problem. As the number of protein structures in PDB is growing at an exponential rate, there is clearly a need for more reliable and efficient methods for protein domain decomposition simply to keep the domain databases up-to-date. RESULTS We present a new algorith...
