Geothermal systems in the Chalk of the south east of England: methods of predicting thermal transport in a fractured aquifer
… aquifer beneath London to supply "open loop" geothermal systems (Environment Agency, 2007). However, there has been little research conducted on how the water re-injected by these systems, which often differs in temperature by as much as 10°C, will interact with the fractured Chalk aquifer in …

Determining Heat Island Response to Varying Land Cover Changes Between 2004 and 2017 Within the City of Reno, Nevada
… Reno-Sparks, Nevada. Free and widely available thermal data from Landsat 7 ETM+ (Enhanced Thematic Mapper Plus) sensor was gathered for a period between 2004 and 2017 and processed to at-satellite surface temperature. Using parcel data and the National Land Cover Database, the time series of …

Assessment of Hyporheic Exchange at In-stream Restoration Structures on Savage River, Garrett County, Maryland
… restoration structures. Hydrometric and thermal data were collected in the streambed near three restoration structures and at a reference site. The hydrometric data indicated that hyporheic flow paths may not have fully developed in the first 16 months following construction; only one …

An Integrated Time-Temperature Approach for Predicting Mechanical Properties of Quenched and Tempered Steels
… Most of the tempering models reported address isothermal conditions which are not typical of most heating methods used to perform the tempering heat treatment. In this work, a non-isothermal tempering model was developed based on the tempering response of four steel alloys. This tempering model …

Adapting a Cryogen-Free Measurement System for Geological Materials: Method Development for Thermal Conductivity Measurements Below 300 K with Applications to Planetary Science
The thermal properties of airless planetary bodies like asteroids are essential to understanding their thermal evolution. While remote sensing missions collect thermal data, this is limited to surface properties. As such, little is known about internal heat flow. Thermal models are used to predict …
