Native lead, a rare mineral, occurs in a late-stage vein in the world’s largest lead – zinc – silver deposit, at Broken Hill, Australia. The lead-bearing vein consists mainly of laumontite, quartz, biotite and muscovite, together with minor amounts of lead, galena, sphalerite, molybdenite, and rare allanite-(Ce). Three types of fluid inclusions have been identified: two-phase brine inclusions l...

The complement system is an essential part of innate immunity by its role in protection against infections, but it is also involved in waste disposal and in modulating the adaptive immune response. Under physiological conditions complement activation is effectively regulated to restrain it to the required targets and extent, and to prevent collateral host tissue damage. An imbalance between com...

The supply and demand of credit are not always well aligned and matched, as is reflected in the countercyclical excess reserve-to-deposit ratio and interest spread between the lending rate and the deposit rate. We develop a search-based theory of credit allocation to explain the cyclical fluctuations in bank reserves, the interest spread, as well as credit rationing. We show that search frictio...

I further investigated sample 7 by preparing a precipitate, which I then washed twice in alkaline buffer. The supernate from the first and second washes contained 22.5 and 1.0 mg of albumin per liter, respectively, showing that albumin was recovered from the precipitate. These results indicate that the deposit formed in some urines contains albumin; centrifi.igation of samples may sometimes lea...

Silver Queen mint in central British Columbia, is located approximately 35 kilometres south of Houston and 3 kilometres east of 0wt.n Lake (Figure 2-7-1). Although currently inactive, it was worked briefly in the early 1970s for gold. silver, copper, zinc, lead and cadmium. The deposit is hosted by Cretaceous rocks of the informal Tip Top Hill group (78.322.67 Ma, K-Ar whole rock), with the age...
