BACKGROUND: During the mating pheromone response in budding yeast, activation of a mitogen-activated protein kinase (MAP kinase) cascade results in well-characterized changes in cytoskeletal organization and gene expression. Spatial reorganization of genes ...
Interaction of V2O5 with TiO2 during prepn. of V/Ti-oxide catalysts via solid-state reaction was studied using in situ FT-Raman spectroscopy, HRTEM and XPS. This interaction results in the formation of monomeric vanadia species with vanadium in tetrahedral ...
Boron neutron capture therapy (BNCT) is an experimental, binary treatment far brain cancer which requires as the first step that tumor tissue is targeted with a boron-10 containing compound. Subsequent exposure to a thermal neutron flux results in destruct ...
A new parameter, the normalized current efficiency for the electro-combustion has been considered. This parameter allows to eliminate the mass transfer inefficiency and then can be defined as the ability of the anode to promote the electro-oxidn. and to re ...
The reaction rate, the catalyst potential, the catalyst work function and the voltammetric charge were in situ measured during a galvanostatic transient of ethylene combustion on an IrO2 catalyst at 380 Deg. The catalytic activity of an IrO2 catalyst could ...
Overexpression of the adipocyte differentiation and determination factor-1 (ADD-1) or sterol regulatory element binding protein-1 (SREBP-1) induces the expression of numerous genes involved in lipid metabolism, including lipoprotein lipase (LPL). Therefore ...
The anodic oxidn. of H2SO4 to H2S2O8 was investigated on B-doped synthetic diamond electrodes obtained by hot filament chem. vapor deposition. High current efficiency for H2S2O8 formation can be achieved in concd. H2SO4 (7.5 mol dm-3) and using high curren ...
This paper deals with the kinetic study of bulk free radical polymerization of styrene initiated with the commercial bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy)hexane (Lupersol 256). The polymerization kinetics is investigated by D ...
In this paper the electrochem. promotion of RuO2 catalyst was studied for the oxidn. of C2H4 to CO2 and H2O. The reaction rate can be increased of up to a factor of 115 by anodic polarization. A kinetic model for the simulation of the open circuit reaction ...
A new method to investigate atmospheric chemical kinetics is presented. It is based on the pump and probe principle. Preliminary measurements are described on the decay rate of OH in the planetary boundary layer its concentration has been raised by laser f ...
