The focus of this thesis is the mineralogy, chemistry, and the understanding of the origin of small (1-5 cm diameter) miarolitic cavities observed in two altered andesitic dikes on West Spanish Peak, Colorado. Twenty rock samples were collected for analysis, and from them 42 thin sections were made for petrographic investigations. Eight of these thin sections were polished and analyzed with the...

The influence of cultivar and crop year on mineral components of apple fruits was investigated using three cultivars cultivated at Morioka Branch, Fruit Tree Research Station in 1980 to 1982. The mineral components measured were 9 elmemts, i.e. sodium, potassium, magnesium, calcium, iron, manganese, copper, zinc, and phosphorus. The potassium, magnesium, manganese, and phosphorus contents were ...

Co-localization of the elements calcium, potassium, sodium and magnesium with sequestering organelles has been achieved by application of two microscopy techniques on the same cell. Organelles were first localized by laser scanning confocal microscopy (LSCFM) using fluorescent organelle stains. The same cells were then analyzed for elemental distribution with ion microscopy. This approach has i...

General experimental details. All organometallic and catalytic procedures were carried out under an inert atmosphere of argon by using a dual manifold vacuum/argon line and standard schlenk techniques, or in an MBraun glove box. All solvents were predried by refluxing for three days under dinitrogen over the appropriate drying agents (sodium for toluene; potassium for THF; sodium-potassium allo...

Common chanterelle (Cantharellus cibarius) has a high biopotential for use in functional nutrition. The aim of the work is to study effect drying methods on biological value dry mushroom ingredient from fruit bodies mushrooms. Cantharellus cibarius collected Kingisepp district Leningrad region (Russia) were object study. It was found that content main components chemical composition mushrooms s...
