ENHANCING BIOGAS PRODUCTION IN COLD-REGION WASTEWATER TREATMENT USING ULTRASONIC PRETREATMENT AND CO-DIGESTION WITH BREWER’S SPENT GRAIN
… factors such as temperature and pH. Cold-region MWTPs are particularly challenging locations including the currently studies Saskatoon Wastewater Treatment Plant in Saskatoon, Saskatchewan, Canada. As a response to these issues, the purpose of this study was to investigate the …

An integrated wind-powered energy system for residential applications in cold regions
… applications of a remote community in a cold region. The novelty of the system is that it uses a wind turbine to directly power the heat pump, with the sea water as the evaporator that provides a constant temperature, without the need to use the wind turbine to convert the wind energy to …

Mantle thermal evolution of tidally-locked super-earths
… 3.5 billion years of planetary evolution, a cold region (~ 300°C) develops at the antistellar point, spanning the depth of the mantle, and inducing a pseudo-Mode 1 convective pattern. Though initial models have focused on an incoming stellar flux equivalent to that at the Earth, we also …

Multi-Scale Modelling of Cold Regions Hydrology
… issues related to the hydrological cycle. Cold region hydrological models have requirements to calculate phase change in water via consideration of the energy balance which has high spatial variability. This motivates the inclusion of explicit spatial heterogeneity and field-testable …

Simulating and quantifying land-surface biogeochemical, hydrological, and biogeophysical processes using the Community Land Model version 4
… as the root transpiration/water removal and the cold-region infiltration with the soil ice freeze/thaw status involved affect soil water content and soil temperature, and regulate carbon- and nitrogen-stock variations. Last but not least, mineral dust, a type of atmospheric aerosol, alters …

Environmental and economic analysis of thermal energy storage for a district heating system in Bolungarvik
… crisis or the issue of energy insecurity. The “cold regions”, such as the Westfjords, of Iceland are impacted the most since they lack access to geothermal resources for essential heating as well as robust energy infrastructure. Not only must they rely on electricity to meet both their heating …

IMPACTS OF CLIMATE AND REGULATION ON ICE-JAM FLOODING OF NORTHERN RIVERS AND THEIR INLAND DELTAS
In cold region environments, ice-jam floods (IJFs) are important hydrological and hydraulic events that play an important role in floodplain ecology but also pose a major concern for citizens, authorities, insurance companies and government agencies, primarily because they can result in high water …
