Estimating the Rate of Return of Education in the Informal Sector of Ghana
(2013-10-04)
This research aims to investigate the rate of return of education at different educational levels in order to prove that obtaining a basic education is beneficial for employment in the formal and informal sector. The ...
A Case for Changing I-131 Transfer Factors Based on Changes in Dairy Industry Practices
(2013-02-01)
Following a large-scale radioactive release, transfer factors (TF) are used to estimate the amount of radioactive material retained by an organism. These values are based on the concentration of the consumed radionuclide ...
‘Our Tables Have Suffered’: Quantifying consumer market activity of commercially valuable living resources in Chesapeake Bay, 1850-1950
(2013-02-04)
Once the most productive and economically important estuary in the US, Chesapeake Bay remains in poor condition after years of over-harvesting and pollutant run-off. The objective of this study was to quantify the demand ...
Mortuary Correlates of Maya Cranial Shaping in the Pasion Region
(2013-02-04)
In the Pasión region of the Southern Lowlands of Guatemala, the ancient Maya practiced various types of intentional cranial shaping. This permanent body modification was employed by different techniques, such as constricting ...
Evaluating Aeolian Sand Transport Vectors In Dune Blowouts
(2013-02-13)
Grain size distribution is the reflection of the feedback between sediment transport system and morphologic change of beach systems. In this respect, early models suggest that grain size can be used to determine the transport ...
Seawater Osmium Isotope Records from Pacific ODP and IODP Sites- Refining the Paleogene Curve and Dating Red Clay Sequences
(2013-02-04)
Reconstructing ancient ocean circulation patterns contributes to a better understanding of Earth’s past climate conditions, as the two are known to be a strongly coupled system. Paleoceanographic reconstructions of the ...
Application of Cellular Microencapsulation to Wastewater Nitrogen Removal
(2013-03-24)
Microencapsulation of cells is a technique in which cells are enclosed in microscopic spheroids of a desired substance, with applications in many fields, such as biomedical engineering. In this study, a microfluidic approach ...
Studying Hydraulic Fracturing through Time-variant Seismic Anisotropy
(2013-10-01)
Hydraulic fracturing is an important modern technique of exploiting natural gas and oil, in which a high-pressure liquid mixture is injected into a wellbore to create small fractures in order to release fluids such as ...
Environmental factors influencing benthic macrofaunal invertebrate community structure in the Flower Gardens East Bank
(2013-09-25)
The Flower Garden Banks consist of two salt domes raised above the continental shelf in the Gulf of Mexico roughly 190 km southeast of Galveston, Texas. With mean annual temperature variations of 18 to 32°C and relatively ...
Strategies for Improved Biosonar Performance in Bat Social Networks
(2013-12-04)
For decades researchers have wondered how echolocating bats avoid interfering with one other’s sonar while flying in dense swarms or in crowded roosts. This thesis explores how groups of bats manage this by applying lessons ...
