The effects of biochar on soil mineral availability
… enhance soil fertility, mainly by improving its water-holding capacity, aeration conditions, aggregate formation, pH, SOM and CEC while enhancing the nutrients availability, crop yields and microorganisms’ activity. This study investigated the effects of 3 different biochar amendments (10 Mgha-1, …

Long-term effects of land application of poultry manure on crop production, and soil and water quality under a corn-soybean rotation system in Iowa
… to environmental quality (surface and subsurface water and air quality) from increased volumes of poultry manure. Although the effect of poultry manure on crop production has been studied, its effects on water quality, under corn and soybean rotation, in Iowa have not been extensively studied. …

INFLOW: Spatially Integrating Local Water Capture into Gugulethu and Surrounds, Cape Town
… in recent years has placed pressure on the water supply infrastructure, with dams at times, precariously low. To address this, stormwater harvesting is being considered as part of diversification strategies aimed at augmenting the current water resources. This local water capture strategy …

High resolution time-series modeling of domestic hot water heating systems
This thesis evaluates domestic water heating systems in conjunction with energy saving technologies such as solar water heating, drain water heat recovery, and heat pump water heating. Five dynamic models are developed using Matlab Simulink® with a time-step of one minute. Using minute resolution …

A novel heat pump cycle to enable the flexible storage and deployment of harvested waste heat in cold climates
… pump system. Waste heat may be harvested from drain water or similar source, stored in the PCM and then deployed to heat a residential space using this concept. A system model was constructed for the proposed system as well for two baseline cases. The model demonstrates that when waste heat is …

Isolation, Characterization, And Application Of Novel Bacteriophages For Preventing Experimental Infection With Mycobacterium avium subspecies paratuberculosis (MAP) Of Dairy Calves
… through the ingestion of contaminated feed and water. Due to JD's prolonged subclinical phase and the absence of a cure, conventional test-based culling has proven ineffective in curbing its spread. Mycobacteriophages, as potential anti-mycobacterial agents, offer promise in controlling …

Remote Sensing Methods To Classify a Desert Wetland
… of the disposal of brackish agricultural waste water from the U.S. into the intertidal zone of the river delta in Mexico, but has become an internationally important wetland for resident and migratory water birds. The marsh is dominated by Typha domengensis with Phragmites australis as a …

Copying strategies to chronic floods in Kuku residential area in Lusaka district, Zambia: a hermeneutic phenomenology study.
… such as the inability of the residential area to drain water, change of rainfall pattern, increase of built environment without sustainable drainages and poor garbage disposal with emphasis on the non-biodegradable materials. Incidentally, this study entails the captured raw lived experiences of …

Enhancing Pavement Surface Macrotexture Characterization
… index based on the Effective Area for Water Evacuation (EAWE), which: (1) Estimates the potential of the pavement to drain water and (2) Correlates better with two pavement surface properties affected by macrotexture (friction and noise) that the current MPD method. The proposed index …

A modeling framework for characterizing root exudation-driven geochemical dynamics in the Critical Zone
… shifts in the transport and transformation of water, carbon, and nutrients across landscapes. The long-term implications of such changes on soil health and water chemistry remain an open challenge, and the mechanisms that drive changes in solute chemistry and eventually stream water chemistry …

River channel dynamics mapped with dense lidar point cloud time series
… landforms are created by lowland rivers that drain water, sediment, and organic matter from upland landscapes. Many of these are self-formed alluvial river channels that have a bed and banks made of mobile material. Interactions between the flow and the material lining the channel cause …

Domestic graywater heat recovery from the UIUC 2009 solar decathlon house
This study investigates the potential for waste water heat recovery in a residential application. A heat exchanger is utilized to transfer heat from the waste water drain line of a residence to the incoming water supply line. An experiment is conducted on the University of Illinois 2009 Solar …
