Mineralogical Notes Transformation Mechanism between High - Quartz and Keatite Phases
As announced in the Amer. M'inerol. 55, 1080 (1970) the summer meeting of the A.C.A. included a Special Session on Mineralogical Crystallography. Fifteen papers were given in a full-day session; abstracts are printed below. In a brief discussion at the end of the day the participants, who included the presidents of the A.C.A., M.A.C., and M.S.A., voted unanimously that the Session on Mineralogi...

This paper presents a preliminary investigation of a new interesting method to build easy to use and representative workloads to evaluate file-systems. The basic principle is to instrument a file-system, with the aid of domain knowledge, to breakdown workloads into micro-functions; then a subset of micro-functions are selected as predictors of a particular type of workload function; and finally...

Clearly F ≤ EH ≤ E. On the other hand, given an intermediate field K between F and E, i.e. a subfield of E containing F , so that F ≤ K ≤ E, we can define Gal(E/K) and Gal(E/K) is clearly a subgroup of Gal(E/F ), since if σ(a) = a for all a ∈ K, then σ(a) = a for all a ∈ F . Thus we have two constructions: one associates an intermediate field to a subgroup of Gal(E/F ), and the other associates...

Tile crystal structures of sjogrenite and pyroaurite, two stacking modifications of approximate composition Mg.Fe.(OH),.(CO.).4H.O, have been determined by X-ray diffraction using three-dimensional methods. Sjogrenite is hexagonal, with a 3,13, C 15.66 A, space group P6.!mmc, Z = !; pyroaurite is rhombohedral, with aH 3,13, CH 23.49 A, space group R3m or R3m, Z = i. Both structures are based on...

6. Urinary tract infections.?In acute cystitis and pyelitis and in chronic infection due to coli bacilli sulphanilamide is adequate but sulphacetamide has been particularly recommended because of its high solubility in urine. Its sodium salt (albucid soluble) may be injected intravenously in 30 per cent solution. Sulphathiazole or sulphadiazine may be given in resistant cases. The average daily...
