Part-crystalline part-liquid state and rattling-like thermal damping in materials with chemical-bond hierarchy [Physics]

21.10.2014 | Wujie Qiu; Lili Xi; Ping Wei; Xuezhi Ke; Jihui Yang; Wenqing Zhang, Proceedings of the National Academy of Sciences current issue, 2014

Understanding thermal and phonon transport in solids has been of great importance in many disciplines such as thermoelectric materials, which usually requires an extremely low lattice thermal conductivity (LTC). By analyzing the finite-temperature structural and vibrational characteristics of ...

Energies, Vol. 7, Pages 6689-6720: Seismic Velocity/Temperature Correlations and a Possible New Geothermometer: Insights from Exploration of a High-Temperature Geothermal System on Montserrat, West Indies

17.10.2014 | Ryan, Graham Alexander; Shalev, Eylon, Energies, 2014

In 2013, two production wells were drilled into a geothermal reservoir on Montserrat, W.I. (West Indies) Drilling results confirmed the main features of a previously developed conceptual model. The results confirm that below ~220 °C there is a negative correlation between reservoir temperature ...

Stabilization of Homoserine-O-Succinyltransferase (MetA) Decreases the Frequency of Persisters in Escherichia coli under Stressful Conditions

17.10.2014 | Elena A. Mordukhova et al., PLoS ONE, 2014

by Elena A. Mordukhova, Jae-Gu Pan Bacterial persisters are a small subpopulation of cells that exhibit multi-drug tolerance without genetic changes. Generally, persistence is associated with a dormant state in which the microbial cells are metabolically inactive. The bacterial response to ...

Soil Temperature Determines the Reaction of Olive Cultivars to Verticillium dahliae Pathotypes

17.10.2014 | Rocío Calderón et al., PLoS ONE, 2014

by Rocío Calderón, Carlos Lucena, José L. Trapero-Casas, Pablo J. Zarco-Tejada, Juan A. Navas-Cortés Background Development of Verticillium wilt in olive, caused by the soil-borne fungus Verticillium dahliae, can be influenced by biotic and environmental factors. In this study we modeled i) the ...

Caenorhabditis elegans RSD-2 and RSD-6 promote germ cell immortality by maintaining small interfering RNA populations [Genetics]

14.10.2014 | Aisa Sakaguchi; Peter Sarkies; Matt Simon; Anna-Lisa Doebley; Leonard D. Goldstein; Ashley Hedges; Kohta Ikegami; St ..., Proceedings of the National Academy of Sciences current issue, 2014

Germ cells are maintained in a pristine non-aging state as they proliferate over generations. Here, we show that a novel function of the Caenorhabditis elegans RNA interference proteins RNAi spreading defective (RSD)-2 and RSD-6 is to promote germ cell immortality at high temperature. rsd mutants ...

Energies, Vol. 7, Pages 6571-6592: Modeling and Control of a Parallel Waste Heat Recovery System for Euro-VI Heavy-Duty Diesel Engines

14.10.2014 | Feru, Emanuel ; Willems, Frank ; de Jager, Bram ; Steinbuch, Maarten, Energies, 2014

This paper presents the modeling and control of a waste heat recovery systemfor a Euro-VI heavy-duty truck engine. The considered waste heat recovery system consists of two parallel evaporators with expander and pumps mechanically coupled to the engine crankshaft. Compared to previous work, the ...
