Heavy Metal Contamination Of Road Dust In Lanzhou, China
(Environmental & Earth Science, 2012-07-25)
Road dusts were collected from the streets of the city of Lanzhou, the capital and largest city of Gansu Province in Northwest China. The potential health hazard posed by contaminated road dusts may be considerable for ...
Bismuth-based Oxide Semiconductors: Mild Synthesis And Practical Applications
(Environmental & Earth Science, 2012-04-11)
In this dissertation study, bismuth based oxide semiconductors were prepared using 'mild' synthesis techniques - electrodepostion and solution combustion synthesis. Potential environmental remediation and solar energy ...
Chemostratigraphy, Paleoceanography, And Sequence Stratigraphy Of The Pennsylvanian-permian Section In The Midland Basin Of West Texas With Focus On The Wolfcamp Formation
(Geology, 2012-07-25)
The late Pennsylvanian to early Permian rocks (Wolfcampian and Leonardian) of the Midland Basin represent a single lithologic unit composed primarily of calcareous mudrocks, siliceous mudrocks, muddy carbonate-clast ...
Morphology Of The Lower Missouri River: The Processes Involving Development Of Highly Sinuous Gooseneck Loop Cutoffs Exposed In The Surficial Deposits Of The River Floodplain
(Geology, 2012-04-11)
Mapping the surficial deposits of the Missouri River from Sioux City, Iowa to Mondamin, Iowa brought to light a prominent set of landforms exposed in the floodplain and which are also easily visible via aerial photography. ...
Identifying Possible Hydrologic Recharge Zones In The Sangre de Cristo Aquifer on The Milliken Ranch in Las Vegas, NM
(Geology, 2012-04-11)
Groundwater at the periphery of mountain ranges in the desert southwest has its provenance in two possible sources: local or regional flow. This study sought to identify the source of deep groundwater from wells on ranches ...
Surface Lineaments And Lithofacies Distribution Of The Tyler Formation In Southwestern North Dakota
(Geology, 2012-07-25)
The purpose of this study is to investigate whether a correlation exists between surface lineaments and lithofacies distribution of the Pennsylvanian Tyler Formation in the southwest portion of North Dakota of the Williston ...
Predicting The Geographic Distribution Of Ancient Soils With Special Reference To The Cretaceous
(Environmental & Earth Science, 2012-04-11)
Different kinds of soils form in different climatic regimes. Soils closely match climatic conditions. Therefore, they are one of the best indicators of past climates. This study uses the "climate envelope" technique developed ...
Proximity Of Cancer Cases To Airports Within The State Of Texas
(Environmental & Earth Science, 2012-07-25)
Determining whether the incidence of cancer may be associated with pollutants emitted from airports is important in order to better plan cities to reduce such incidences. This research aims to answer the following questions: ...
Microfaunal Assemblages Of The Placid Shale (Missourian, Upper Pennsylvanian), Brazos River Valley, North-Central Texas
(Geology, 2012-07-25)
The Pennsylvanian and lowermost part of the Permian strata in North-Central Texas is assigned to the Strawn, Canyon, and Cisco Groups. The Canyon Group is approximately equivalent to the middle-upper part of the Missourian ...
On-road Measurement Of NOx And CO₂ Emissions From Biodiesel Produced From Different Feedstocks
(Environmental & Earth Science, 2012-07-25)
Biodiesel has generated increased interest in the US and elsewhere recently as an alternative to petroleum-derived diesel. Because it can be produced from domestic feedstocks such as soybeans, canola oil, and even recycled ...
