Thermal remediation techniques, such as hot water flooding, are emerging technologies that have been proposed for the removal of nonaqueous phase liquids (NAPLs) from the subsurface. In this study a combined laboratory and modeling investigation was conducted to determine if hot water flooding techniques would improve NAPL mass removal compared to ambient temperature water flushing. Two experim...

With the urbanization process of the hot summer and cold winter (HSCW) zone in China, the energy consumption of space and water heating in urban residential buildings of the HSCW zone has increased rapidly. This study presents the energy efficiency and sustainability evaluation of various ways of space and water heating taking 10 typical cities in the HSCW zone as research cases. Two indicators...

The Thermoactinomyces sp. strain Gus2-1 was isolated from hot-spring sediments sample from the hot-spring Gusikha in Bargusin Valley (Baikal Rift Zone, Russia). The sequenced and annotated genome is 2,623,309 bp and encodes 2513 genes. The draft genome sequence of the Thermoactinomyces sp. strain Gus2-1 has been deposited at DDBJ/EMBL/GenBank under the accession JPZM01000000 and the sequences c...

[1] Riparian ecosystems are characterized by spatial and temporal heterogeneity in physical and biological attributes, with consequences for nutrient cycling. We investigated the responses of carbon (C) and nitrogen (N) cycling processes to the hydrogeomorphic template in the riparian zone of the San Pedro River, Arizona, a large (catchment area !11,500 km), free-flowing, semiarid river. Over a...

The present study investigates the effectiveness of thermostat control strategy in cooling energy consumption in residential buildings. To evaluate the energy consumption, two scenarios including a residential zone with and without the thermostat control system are assumed. The TRNSYS software provides an efficient numerical tool to model and evaluate a cooling system. Furthermore, since solar-...

Ad-hoc networks have become a hot topic in the research world. Routing in ad-hoc networks has faced so many problems due to the peculiar nature of ad hoc environments. In this paper a new routing protocol based on source routing and zone based routing is proposed. Proactive source routing protocol (PSR) is a method to reduce overhead in ad hoc networks by making use of BFSTs (Breadth First Span...

Hong Jiang began his talk by discussing the importance of data recovery. Disk failures have become more common in RAID-structured storage systems. The improvement in disk capacity has far outpaced improvements in disk bandwidth, lengthening the overall RAID recovery time. Also, disk drive reliability has improved slowly, resulting in a very high overall failure rate in a large-scale RAID storag...
