A crop that has a higher resistance against the negative impact of stress. Stronger cell walls. A stronger defense against plant infections and pests. A stronger defense against temperature differences and/or extreme temperatures. A higher quality and yield. A higher dry weight content of the end product. defined with respect to certain types of structure, largely in the light of experience gained since in the Beilstein Institute and elsewhere. The system is now extended to deal, on the one hand, with organic-chemical conformations, and, on the other, with inorganic- chemical configurations to ligancy six.

A glass is by definition a liquid at all temperatures. Compositionally a typical glass consists of the 'glass (or network) formers' (SiO 2 and B 2 O 3), fluxes (also called alkaline metals, K 2 O and Na 2 O), and the network (or matrix) modifying alkaline earths (CaO, BaO, PbO, ZnO).

The thermal oxidation of silicon in various gaseous atmospheres has been studied and the growth rate data and activation energies determined.
The oxide layers contained defects, the density of which increased with increasing temperature and time; microcracks were also observed. The devitrification of these oxides was studied at ° C and above in argon-oxygen atmospheres; water Cited by: A FORMATIONAL MODEL FOR AN IMPACT MELT-BEARING BRECCIA DYKE AT THE MISTASTIN LAKE IMPACT STRUCTURE, LABRADOR, CANADA.

Recent destructive earthquakes have clearly shown that near-surface geological conditions play a major role in the level of ground shaking in urban areas. In Canada, Montreal is ranked second for seismic risk after Vancouver considering its population and regional seismic hazard.
The city is largely built on recent unconsolidated marine and river deposits and most of its infrastructure is old Cited by: A multistage model for the origin and emplacement of impact melt rocks and the formation of impact ejecta is proposed for the Mistastin Lake impact structure based on a synthesis of the field and.

Petrographic and geochemical observations also confirmed that dissolution occurred under deep-burial conditions after incipient pressure solution. Dissolution was not confined to the centers of dolomitized grains, as is commonly seen when remnant calcitic grains dissolve out during the advanced stages of replacement by: Experimental devitrification of natural rhyolitic glass was undertaken in an attempt to produce, under known conditions, analogs of naturally devitrified rocks.
The results should facilitate the recognition and interpretation of devitrification by: Tectonic and Eustatic Controls on Deposition of the Harmon, Cadotte and Paddy Members of the Albian Peace River Formation, Alberta and British Columbia, Canada Robin A.

Both of these komatiitic lava flows developed layering during differentiation and cooling. In Fred's Flow the layering has been divided into four zones by Arndt et al. (): a brecciated or spinifex upper unit, a gabbroic interior, a lower cumulate zone and a basal zone (Fig.
1).Many aspects of the history of natural glasses are related to the physicochemical properties of silicate melts. Glasses are thermodynamically unstable; with time and under a variety of conditions, they become crystalline.
When little water is present, devitrification may be described in much the same terms as those which apply to the crystallization of silicate by:
