Rates of hypolimnetic oxygen depletion can be predictedfrom a knowledge of a lake's phosphorus retention, the average hypolimnetic temperature, and the mean thickness of the hypolimnion. Areal oxygen deficits cannot be used to index lake trophic status because areal calculations do not eliminate the influence of hypo-limnetic morphometry.

Modem geology was founded by James Hutton at the end of the 18th cenhuy as an observational, descriptive, qualitative, and subjective science. It was the pioneer work of Pearson (1901) and Spearman (1904) in statistics applied to agriculture, biology, medicine, and psychology, that led to the first major inroads of quantitative techniques in geology and the models they used were above all stati...

The Dawn spacecraft collected over 28,000 images and a wealth of spectral data of Vesta’s surface. These data enable analysis of Vesta’s diverse geology including impact craters of all sizes and unusual shapes, a variety of ejecta blankets, large troughs, impact basins, enigmatic dark material, and considerable evidence for mass wasting and surface alteration processes [1,2,3]. Two large impact...

pillow lavas are locally conspicuous. A unit consisting of dark, thinly bedded sandstone and siltstone, lccally ranging to several hundred feet thick, is lowermost in the exposed section. The middle division consists of about 3,500 feet of mixed andesi.:e and basalt volcaniclastic rocks ~ lahar, tuff breccia, volcanic sandstone, and conglomeratic beds which rest on relatively thin, fossiliferou...

One of the basic concepts of set theoretic geology is the mantle of a model of set theory V: it is the intersection of all grounds of V, that is, of all inner models M of V such that V is a set-forcing extension of M . The main theme of the present paper is to identify situations in which the mantle turns out to be a fine structural extender model. The first main result is that this is the case...

when the a particle is initially in the state i. The Sij's are determined from the relative intensity of the lines emitted in transition from that state. Take the particular case where S12 = S02 = 1/2 and (12 = #o2 = (01 1-7 13= 1/200 then P1/P2 = 4.3. This ratio is nearly the same as that of the internal conversion coefficient of y rays from RaC. There the values of this coefficient can be div...
