Spring Hill

Dr. Burke received his B.S. degree in chemistry at Spring Hill College in 1961 and his Ph.D. in organic chemistry in 1965 at the University of California, Berkeley, where he was an NSF Predoctoral Fellow. Before joining Rohm and Haas as a Senior Research Scientist, he was a National Institutes of Health Postdoctoral Fellow at Columbia University. 

A natural answer proposed by Terrell Hill and colleagues [6] is that the direction of motion is governed by the asymmetry of the spring. Hill et al. [6] explicitly described the motion of the actin filament in terms of an asymmetric free-energy landscape for the actin site as shown in Fig. 4, where in the attached state the myosin exerts a position-dependent force on the actin, and in the detached state...

The spring water issuing through fissures in the hills, which are only masses of coal, is so impregnated with bituminous and sulphurous particles as to be frequently nauseous to the taste and prejudicial to the health. (T. M. Morris, 1803, in Mac-Kenthum, 1969)... 

Figure 2,108 Piezoelectric quartz crystal with vacuum-deposited electrodes. Gold is deposited on both sides of the quartz wafer a in the pattern shown. Electrical connection is made to the electrode flag b by means of a spring clip with attached lead c. The circular gold electrode in the crystal centre d opposes an identical electrode on the other side of the crystal. Electrical connection to the opposing electrode is made to the electrode flag e.

We collected sets of single-shot broadband LIBS spectra in the Army Research LIBS Laboratory for 27 obsidian samples from major sites across the CVF as well as for samples from 4 other California obsidian locations - Bodie Hills, Mt. Hicks, Fish Springs, and Shoshone. The resultant obsidian LIBS spectral database was analyzed by multivariate statistical analysis. 

A model was built for discriminating the five distinct obsidian localities (Coso, Mt. Hicks, Fish Springs, Shoshone, and Bodie Hills), the broadband LIBS spectra for which exhibit a high degree of visual similarity 100% of the 200 test single-shot spectra were correctly classified with that model (Table 1). In other words, obsidian samples from the 5 regions are easily distinguishable with LIBS. 

Symptoms Mounds of loose soil ("mole hills"). Light, well-drained soils are most affected. Damage is usually greatest in late winter and early spring.
