Environmental Science Projects

Green roofs are becoming popular in the United States for their runoff and energy reduction abilities. However, current designs have high installation costs, heavy load-bearing requirements, and restrictions to low-sloped roofs. We designed a novel retrofit technology, the green cloak, ...

The design, analysis, and control of bio-systems remain an engineering challenge. This is mainly due to the material heterogeneity, boundary irregularity, and nonlinear dynamics associated with these systems. The recent developments in imaging techniques and stochastic upscaling methods provides a ...

A laser ranging image system was developed for on-line high-resolution 3D shape recovery of poultry fillets. The range imaging system in conjunction with X-ray imaging was used to provide synergistic imaging detection of bone fragments in poultry fillets. In this ...

The engineering of technoecosystems (technological-ecological hybrids) was investigated, focusing specifically on novel behavior exhibited by an ecosystem when given control over its own energy sources via artificial feedback control circuits. A technoecosystem was constructed based upon wetland soil microcosms using ...

This research quantified the effectiveness of agricultural riparian buffers to protect stream health in Maryland's Coastal Plain and Piedmont physiographic regions. Easily-obtainable data were used to develop scientific guidance for buffer management strategies. Three data sets were used: the 1998 ...

Salmonella and other pathogenic organisms that infect poultry and other livestock can originate from feed or the environment. Technologies to control Salmonella infection in poultry are important measures taken to reduce turkey and poultry production losses. A study was designed ...

The ability of air biofilters to remove carbon monoxide (CO), a priority pollutant that harms human and environmental health was investigated. Environmental accounting of biofilters was performed using emergy analysis to compare resource requirements of biofilters to catalytic converters. Cylindrical ...

This study tested the ability of two non-invasive techniques, thermography and near-infrared multi-spectral imaging, to quantitatively assess the response of mouse skin to a single dose of X-ray irradiation. Thermal images from an 8-12 micron thermal camera were recorded after ...

Contamination of natural waters by microorganisms directly affects public health. Field application of manure can potentially result in surface and groundwater contamination. The objective of this study was to observe and quantify the effects of vegetated filter strips (VFS) on ...

This model emphasized respiratory responses and incorporated mathematical descriptions of experimental results obtained from exercising humans. Prediction equations for tidal volume, anaerobic threshold, minute volume, respiratory work, and performance time were included, as well as dynamic changes in each. This ...
