Relationship Between Third Grade Teachers’ and Students’ Reports on Frequencies of Interactivity During Reading Instruction
(2010-11-11)
According to many educators “formal education is essentially a social process” (Weinstein, 1991, p. 295) that is most effective when there is a two-way interaction that results in discourse among and between teachers and ...
A Gateway-Based Approach for Information Retrieval from Data-Centric Wireless Sensor Networks from IP Hosts
(2010-11-11)
With applications ranging from environmental and health monitoring to military surveillance and inventory tracking, wireless sensor networks (WSNs) are changing the way we collect and use data and will be a major part of ...
The role of host sea anemones in the cleaning mutualism between anemoneshrimp and client fishes
(2010-11-11)
Cleaning symbioses may strongly impact the diversity of coral reef fishes, but little is known about the dynamics of mutualistic networks involving cleaner shrimps that form obligate associations with sea anemones. I used ...
The Influence of Image Congruence and Perceived Fit on e-Store Patronage Intention for Multichannel Apparel Retailers
(2010-11-11)
As online retail sales continue to grow, consumers are turning to the Internet in ever increasing numbers. Despite the prevalence of retailers’ e-stores and the importance of online branding, there exist few studies on the ...
Test time optimization in scan circuits
(2010-11-10)
As circuit sizes increase with scale down in technology, the time required to test the circuits also increases. Expensive automatic test equipment (ATE) is used to test these circuits and the cost of testing becomes a ...
Desulfurization of Hydrocarbon Fuels at Ambient Conditions Using Supported Silver Oxide-Titania Sorbents
(2010-11-10)
Sulfur in refined fuels is considered a significant cause for atmospheric pollution such as acid rain and smog. Sulfur is also a poison for electrocatalysts in fuel cells and catalysts in hydrocarbon refining and reformation ...
Development of Fertilizer Recommendations for Native Biofuel Crops and Nutrient Release from Cattle Feces
(2010-11-10)
Plant biomass is a viable raw material for renewable energy production. The use of perennial grasses is a possible option, however information on their nutrient management in the southeastern U.S. is deficient. The ...
Assessing the Status of Professional Learning Opportunities in U.S. Independent Schools
(2010-11-10)
Research has begun to create a consensus about the essential characteristics of professional learning opportunities that impact teachers’ knowledge and practices. These key characteristics include duration, teacher ...
Applications of Stationary Sets in Set Theoretic Topology
(2010-11-10)
The notion of a stationary subset of a regular cardinal, a set which intersects any closed unbounded subset of that cardinal, is a useful tool in investigating certain properties of topological spaces. In this paper we ...
Using and Improving Irrigation: Producer Perceptions and Possibilities
(2010-11-05)
Frost, drought, and other sources of crop stress may be reduced through irrigation. A random sample of Alabama crop, tree, and vegetable producers was surveyed about the nature and extent of irrigation practices and ...
Lane Detection, Calibration, and Attitude Determination with a Multi-Layer Lidar for Vehicle Safety Systems
(2010-11-05)
This thesis develops a lane detection algorithm which extracts lane markings from the road's surface in an effort to ascertain the lateral position of the vehicle in the lane using a lidar, with the goal of being incorporated ...
Equilibrium Concentrations of Major Cations and Total Alkalinity in Laboratory Soil-Water Systems
(2010-11-05)
Three kinds of soils and four kinds of water were used to prepare laboratory soil-water mesocosms. Soil-water mesocosms were prepared containing 5-cm deep layers of soil and 21 L of water from each of the four sources. ...
Rapid Wound Repair in the Ctenophore Mnemiopsis spp.
