Heat pipes are a type of passive and efficient two-phase devices. Despite its wide applications in solar collectors, electronic cooling energy recovery systems, the heat pipe technology has been stagnant last two decades. Though, numerous designs to enhance evaporation mass transportation have explored since discovery, intrinsic limitation induced by filmwise condensation (FWC) condenser sectio...

This research aims to achieve a greater understanding of the structure of bacterial communities present in alkaline hot springs in Yellowstone National Park. I focus specifically on White Creek and Rabbit Creek in the Lower Geyser Basin. I show that, overall, the bacterial communities of both creeks are non-randomly assembled. However, at finer taxonomic scales, bacterial groups differ in their...

A novel anaerobic, thermophilic, Fe(III)-reducing, CO-utilizing bacterium, strain 1315(T), was isolated from a hot spring of Geyser Valley on the Kamchatka Peninsula. Cells of the new isolate were Gram-positive, short rods. Growth was observed at 52-70 degrees C, with an optimum at 65 degrees C, and at pH 5.5-8.5, with an optimum at pH 6.5-7.2. In the presence of Fe(III) or 9,10-anthraquinone 2...

Stationary time series models built from parametric distributions are, in general, limited in scope due to the assumptions imposed on the residual distribution and autoregression relationship. We present a modeling approach for univariate time series data, which makes no assumptions of stationarity, and can accommodate complex dynamics and capture non-standard distributions. The model for the t...

We analyze statistical features of background and clustered subpopulations of earthquakes in different regions in an effort to distinguish between human-induced and natural seismicity. Analysis of end-member areas known to be dominated by humaninduced earthquakes (The Geyser geothermal field in northern California and TauTona gold mine in South Africa) and regular tectonic activity (the San Jac...

Geysers, which involve the explosive release of water through vertical shafts connected to a nearly horizontal pipeline, have been attributed to either pipeline surge or the release of air. Laboratory experiments involving the release of a large entrapped pocket of air through a surcharged vertical riser indicate that the air can force water upward in the shaft but that a jet such as seen in vi...

William Julius Wilson (bill_wilson @harvard.edu) is the Lewis P. and Linda L. Geyser University Professor at Harvard University and the author of several award-winning books, including The Declining Significance of Race (1980); The Truly Disadvantaged (1987); and When Work Disappears (2006). His précis is drawn from More Than Just Race: Being Black and Poor in the Inner City (W.W. Norton Co., 2...

This paper considers how divorce law alters the incentives for couples to invest in their marriage, focusing on the impact of unilateral divorce laws on investments in new marriages. Differences across states between 1970 and 1980 provide useful quasi-experimental variation with which to consider incentives to invest in several types of marriage-specific capital: spouse’s education, children, h...

Environmental gradients are expected to promote the diversification and coexistence of ecological specialists adapted to local conditions. Consistent with this view, genera of phototrophic microorganisms in alkaline geothermal systems generally appear to consist of anciently divergent populations which have specialized on different temperature habitats. At White Creek (Lower Geyser Basin, Yello...
