birch (betula sp.) is considered as extinction species and its natural regeneration in iranian forests ‎is very slow. difficulties in regeneration as well as natural seed germination of birch tree besides ‎high levels of seed contaminations have justified the application in‏ ‏vitro culture with respect to its ‎conservation and genetic improvement. hence, the in vitro culture initiation using se...

x-ray photoelectron and high resolution electron energy loss spectroscopic (xps-hreels) studies have shown that the adsorption of carbon dioxide at mg(100) surfaces at 80k is followed by a dissociative reaction leading to the formation of a metastable surface carbonate above 80k. the formation of a carbonate species is proposed to proceed through oxidation of c0 (g) by an active oxygen surface ...

Gold nanoparticles immobilized on gold surfaces (AuNPs/Au) function as an excellent SERS substrate for the detection of bacteria biomarkers. The possibility of the reactivity of bacteria biomarkers on such a nanoparticle-based substrate poses complications for the spectroscopic identification and quantification. This report describes new findings of an investigation of the SERS characteristics ...

Plasma technology is progressing rapidly, although there is still a need for much research and development. In situ diagnostics such as emission spectroscopy are set up to control the plasma processes. Two experiments concerning treatments of polymer and steel surfaces using a flowing post-discharge plasma of O2 and N2 are described. The diagnostics of O and N atom densities have been correlate...

The terminal velocity of rising microbubbles is a sensitive function of the bubble size and the surface concentration of mobile insoluble surfactants at the gas/liquid interface due to the Marangoni effect. With a model that allows for surface convection and diffusion, we delineate the regimes when the terminal velocity varies between the fully mobile (Hadamard-Rybczynski) and the fully immobil...

relationship between plant and sial has special importance, because it is judged about one by considering the another one. soil-plant relationship is used for range trend, range emdttton, range suitability in range species. this research, includes: the analysis of plant different types and dominant species in each type with soil factors such as percentage of lime clay depth, stone and gravel (s...

Stem density, basal area, vegetation cover and vegetation surface area were compared as measures of the proportions of plant species present in North Okarito Forest, South Westland, for use in determining bird preferences for plant species. In general, stem density estimates of the proportions of canopy species were about 10 times lower than basal area estimates. The converse was true for estim...

FLOSS (fluorescence labeling of surface species) enables one to identify and quantify very low concentrations of surface functional groups. Unlike most surface analytical techniques, FLOSS can provide absolute, as well as relative, surface coverage determination. However, as with any other surface derivatization technique, FLOSS provides a lower limit to surface coverage. The specificity of FLO...
