Abstract:
The relative water demand (RWD) of containergrown seedlings of red maple, green ash, Washington hawthorn, honeylocust and flowering crabapple was determined for the period mid-May through August by comparing water consumption values and potential evapotranspiration rates with growth rates. While RWD for red maple was high, actual water consumption based on changes in plant size (water use index, WUI) was quite low, indicating efficient use of available moisture. RWD for green ash was high, but WUI was also high indicating relative inefficiency in utilizing available water resources. RWD values

Abstract:
Iran is located in a dry climate belt. Such conditions have made the supply of urban water resources one of the most fundamental management challenges. The amount of water consumed in a city is affected by the weather conditions greatly such that as the weather changes, the amount of water consumed changes as well. In this study, several models including zero-order Pearson’s correlation coefficient, first-order Pearson’s correlation, generalized additive model (GAM), generalized linear model (GLM), support vector machine (SVM-Nu), and simplex optimization algorithm were used in order to identi

Water managers have increasingly shown that demand management solutions are more important than searching for alternative sources to resolve the challenges and shortages of water supply services.

Using the connection between water and energy as a case study, we present a model that uses the effects of geospatial and temporal context on embedded energy to approximate resource sustainability for water. First, the basic steps of calculating the energy intensity for a given location are discussed. Intensity is presented in units of energy per volume of water. In the case of supplying fresh water, energy intensity depends upon the quality of the original resource, its location relative to the end use location, and the type of technology in use to move and treat the water.

Abstract:
Abstract The refrigerants and electricity consumption of existing air conditioning systems create significant greenhouse gas (GHG) emissions. This work describes a new air conditioning cycle that uses a lower critical solution temperature (LCST) liquid mixture to provide dehumidification and cooling. The cycle uses no refrigerants and is driven by low-grade heat. Upon heating, the LCST mixture phase separates into a water-rich phase and a water-scarce phase. After cooling both phases to ambient temperature, the water-scarce phase absorbs moisture from humid air (providing dehumidification), wh

Abstract:
Abstract Emulsions are common during oil production, and this is the case of the Peregrino field, e.g. . In several fields, oil and reservoir fluids can be produced through Electrical Submersible Pumps (ESP) and the formation of emulsion affects the ESP system, its run life, and the production itself. The viscosity increase due to emulsion formation severely hampers the ESP performance, requiring an increase in energy consumption on the platform to keep the same production rate. This work presents an initial validation of the model proposed by Bulgarelli (2021) to predict the water-in-oil emul

Abstract In this paper, we present a validated thermal model of a greenhouse. Then summer climatic data of a location in South of Australia (Port Augusta), known to have dry and hot summer, is used to compare the potential of different cooling technologies in providing cooling to greenhouse indoor air while considering the minimization of water consumption. Several cases are examined and compared to a reference case which is a closed greenhouse without cooling. The operation cases considered for cooling purpose are 1 - Fogging system; 2 - Single pipe Earth-to-Air Heat Exchanger (EAHE); 3 - Mul

Abstract:
Air conditioning systems (AC systems) are the primary driver of summer electricity use and peak power demand in residential homes in Texas, mostly due to the refrigerant compressor in the condenser unit. The power demand for a residential AC compressor is on the order of kilowatts. Peak power demand from residential AC systems could be reduced by means of pre-cooling a thermal storage reservoir, which can be used as a heat sink instead of the air-cooled outdoor condenser that is subject to ambient conditions. The concept of thermal storage is not new, and is in widespread use in large-scale HV

Abstract:
Clean water has a largely unknown economic value, particularly to small communities whose agricultural activities take place on river shores. In November 2015, the rupture of a mining tailings dam in the municipality of Mariana led to a record disposal of toxic residuals in southeast Brazil. A mud avalanche ran out for 600 km (373 miles) until it reached the Atlantic Ocean, leaving behind extreme ecological and economic damage in the Doce River basin. This is the largest environmental disaster in Brazil to date. We quantify the negative externalities using rich, identified, and comprehensive d

Abstract:
The Bingham Canyon Mine, located near Salt Lake City, Utah, is surrounded by more than 6 billion tons of waste rock developed over the open cut mining history from 1903 to present; the surface area of the waste rock is approximately 5000 acres. Waste rock dumps have a thickness of more than 1 200 feet from crest to toe. From 1930 to 2000, selected portions of the waste rock dumps were commercially leached using a ferric-sulfate-based lixiviant to extract copper, whereas other portions have only received meteoric leaching.

The purpose was to understand the most important barriers hindering the UAE’s private sector from achieving wide-scale energy and water efficiency and to begin to identify solutions to mitigate these barriers.
