Opis:
Geographical Information Systems have become essential tools for land analysis and the subsequent decision making in many fields of human activity. In the field of mining, GIS applications have appeared in ore deposit modelling, environmental pollution, or planning of mining spaces. In this research, the powerful multicriteria tools of GIS platforms have been applied for the determination of an index that has been called “Exploitability Index”. This index allows analyzing a series of outcrops of industrial aggregates, to help in the selection of the most adequate one to be enhanced from a mining approach. The multicriteria analysis has been applied for its determination, and as a result of this research, a model is proposed. The main criteria that condition the decision have been established in this model, along with their subsequent hierarchization and their weighting. The proposed model is applied to a specific case: the analysis of a series of outcrops of industrial aggregates (ophites) in Cantabria, Spain. After defining the Exploitability Index for those ophitic outcrops, it has been observed that the only deposit that has been classified as very suitable for its exploitation is the only one that has been really exploited, supporting the proposed methodology.

Opis:
Gas Chromatography coupled with mass spectrometry was applied to study the fragmentation of selected flavonoids from the ethanolic extract of Smilax domingensis Willd., Smilacaceae, known as zarzaparrilla, after Soxhlet extraction during 20 hours. Compounds belonging to one of the major subgroups found in common plants, i.e. flavanols were studied. Following solvent extraction and derivatization using BSTFA, possibly two different metabolites from the same chemical group were characterized in one analytical run: (+)-catechin and (-)-epicatechin. For the very first time, qualitative data on these analytes in the drug were determined after detailed validation of a sensitive, cheap and reliable GC-MS method.
