[Report] Localization-delocalization transition in the dynamics of dipolar-coupled nuclear spins

21.08.2015 | Gonzalo A. Álvarez; Dieter Suter; Robin Kaiser, Science , 2015

Nonequilibrium dynamics of many-body systems are important in many scientific fields. Here, we report the experimental observation of a phase transition of the quantum coherent dynamics of a three-dimensional many-spin system with dipolar interactions. Using nuclear magnetic resonance (NMR) on a ...

Induction of a Torpor-Like State by 5’-AMP Does Not Depend on H 2 S Production

21.08.2015 | George J. Dugbartey et al., PLoS ONE, 2015

by George J. Dugbartey, Hjalmar R. Bouma, Arjen M. Strijkstra, Ate S. Boerema, Robert H. Henning Background Therapeutic hypothermia is used to reduce ischemia/reperfusion injury (IRI) during organ transplantation and major surgery, but does not fully prevent organ injury. Interestingly, ...

Energies, Vol. 8, Pages 8814-8834: Novel Method for Measuring the Heat Collection Rate and Heat Loss Coefficient of Water-in-Glass Evacuated Tube Solar Water Heaters Based on Artificial Neural Networks and Support Vector Machine

20.08.2015 | Liu, Zhijian ; Li, Hao ; Zhang, Xinyu ; Jin, Guangya ; Cheng, Kewei, Energies, 2015

The determinations of heat collection rate and heat loss coefficient are crucial for the evaluation of in service water-in-glass evacuated tube solar water heaters. However, the direct determination requires complex detection devices and a series of standard experiments, which also wastes too ...

Energies, Vol. 8, Pages 8775-8797: Analysis of Unit Process Cost for an Engineering-Scale Pyroprocess Facility Using a Process Costing Method in Korea

18.08.2015 | Kim, Sungki ; Ko, Wonil ; Bang, Sungsig, Energies, 2015

Pyroprocessing, which is a dry recycling method, converts spent nuclear fuel into U (Uranium)/TRU (TRansUranium) metal ingots in a high-temperature molten salt phase. This paper provides the unit process cost of a pyroprocess facility that can process up to 10 tons of pyroprocessing product per ...

[Perspective] Has there been a hiatus?

14.08.2015 | Kevin E. Trenberth, Science , 2015

Every decade since the 1960s has been warmer than the one before, with 2000 to 2009 by far the warmest decade on record (see the figure). However, the role of human-induced climate change has been discounted by some, owing to a markedly reduced increase in global mean surface temperature (GMST) ...

Energies, Vol. 8, Pages 8650-8681: A Closed-Loop Control Strategy for Air Conditioning Loads to Participate in Demand Response

14.08.2015 | Hu, Xiaoqing ; Wang, Beibei ; Yang, Shengchun ; Short, Taylor ; Zhou, Lei, Energies, 2015

Thermostatically controlled loads (TCLs), such as air conditioners (ACs), are important demand response resources—they have a certain heat storage capacity. A change in the operating status of an air conditioner in a small range will not noticeably affect the users’ comfort level. Load control of ...

Energies, Vol. 8, Pages 8704-8715: CO2 Fixation by Membrane Separated NaCl Electrolysis

14.08.2015 | Park, Hyun Sic; Lee, Ju Sung; Han, JunYoung ; Park, Sangwon ; Park, Jinwon ; Min, Byoung Ryul, Energies, 2015

Atmospheric concentrations of carbon dioxide (CO2), a major cause of global warming, have been rising due to industrial development. Carbon capture and storage (CCS), which is regarded as the most effective way to reduce such atmospheric CO2 concentrations, has several environmental and technical ...

Energies, Vol. 8, Pages 8562-8572: Gasification of a Dried Sewage Sludge in a Laboratory Scale Fixed Bed Reactor

12.08.2015 | Werle, Sebastian, Energies, 2015

This paper presents an investigation of sewage sludge gasification in a fixed bed gasifier. Experiments were conducted on a laboratory scale fixed bed gasifier. In the experiments, two types of dried sewage sludge were tested and their properties were analysed. Parameters such as air ratio λ = ...

Energies, Vol. 8, Pages 8497-8515: An Iterative Method to Derive the Equivalent Centrifugal Compressor Performance at Various Operating Conditions: Part I: Modelling of Suction Parameters Impact

12.08.2015 | Albusaidi, Waleed ; Pilidis, Pericles, Energies, 2015

This paper introduces a new iterative method to predict the equivalent centrifugal compressor performance at various operating conditions. The presented theoretical analysis and empirical correlations provide a novel approach to derive the entire compressor map corresponding to various suction ...

Energies, Vol. 8, Pages 8573-8593: Energy Consumption Prediction for Electric Vehicles Based on Real-World Data

12.08.2015 | De Cauwer, Cedric ; Van Mierlo, Joeri ; Coosemans, Thierry, Energies, 2015

Electric vehicle (EV) energy consumption is variable and dependent on a number of external factors such as road topology, traffic, driving style, ambient temperature, etc. The goal of this paper is to detect and quantify correlations between the kinematic parameters of the vehicle and its energy ...
