Organic Rankine-Cycle Turbine Power Plant Utilizing Low Temperature Heat Sources [PDF]
Volume 1B: General, 1980 Utilizing and converting of existing low temperature and waste heat sources by the use of a high efficiency bottoming cycle is attractive and should be possible for many locations. This paper presents a theoretical study on possible combination of an organic Rankine-cycle turbine power plant with the heat pump supplied by waste energy sources.

Imprint of Inhomogeneous Reionization on the Power Spectrum of Galaxy Surveys at High Redshifts
, 2006 We consider the effects of inhomogeneous reionization on the distribution of galaxies at high redshifts. Modulation of the formation process of the ionizing sources by large scale density modes makes reionization inhomogeneous and introduces a spread to ...
