Co-planning and Co-teaching for ELLs
This capstone project seeks to provide the general education teachers and the English as a New Language (ENL) teacher at the Avon Middle School with the strategies and resources they need in order to effectively co-plan and co-teach in the mainstream classroom. The Avon Central School District is a …

Co-Exist
Chinese urban villages which have grown over time have difficulty to operate as a healthy urban environment. As a consequence, residents are often forced to move to the boundary of the city although many prefer its narrow streets and the informality of life. This thesis proposes a modern …

Co-Pyrolysis and Co-Combustion of Coal and Biomass
Sustainability, security of supply, and diversity, as well as economic competitiveness are key components of energy policy. There is increasingly stringent legislation on the environmental impact of energy production, and there is growing pressure to reduce not just NOx and SOx emissions, but also …

NUMERICAL ANALYSIS OF CO-FLOWING IMMISCIBLE LIQUIDS IN CO-AXIAL MICROTUBES
This research developed dimensionless correlations, based on the numerical simulations, for the boundaries between the dripping, transition and jetting regimes. Additional correlations are also developed for the radius and formation frequency of disperse droplet in the dripping regime and the …

Ultrafast electron dynamics in Fe(CO)5 and Cr(CO)6
In this thesis, the two prototype catalysts Fe(CO)₅ and Cr(CO)₆ are investigated with time-resolved photoelectron spectroscopy at a high harmonic setup. In both of these metal carbonyls, a UV photon can induce the dissociation of one or more ligands of the complex. The mechanism of the dissociation …

Selected differences between co-op and non co-op engineering graduates
Virginia Tech Engineering graduates of 1975 were surveyed to determine if salary differences existed between matched groups of co-op and non co-op graduates and to determine if selected variables were related to salaries. The average salary for co-ops was higher for both first and current positions …

In situ study of Co₃O₄ morphology in the CO-PROX reaction
… However, the surface area specific rate of CO₂ formation displayed an inverse trend. In the region of 225 – 250ᵒC, nanocubes > NaOH nanosheet > HCl nanocubes showed maximum activity. The surface area specific rate was the same for amine nanocubes and NaOH nanosheets. None of the model …

Image Co-saliency Detection and Co-segmentation from The Perspective of Commonalities
Image co-saliency detection and image co-segmentation aim to identify the common salient objects and extract them in a group of images. Image co-saliency detection and image co-segmentation are important for many content-based applications such as image retrieval, image editing, and content aware …

Change in co-operative organisations : the case of Greek pharmaceutical co-operatives
This thesis investigates how change unfolds in a certain type of retailer-owned co-operatives; the pharmaceutical co-operatives in Greece. Previous works have identified the type of changes (‘what’) that occurred in (mostly, agricultural) co-operatives and explained them through the “structural …

Analytical modeling of CO₂ migration in saline aquifers for geological CO₂ storage
… a promising tool for reducing global atmospheric CO₂ emissions. Given the environmental and health risks associated with leakage of CO₂ from such a storage site, it is critical to ensure that injected CO₂ remain trapped underground for the foreseeable future. Careful site selection and effective …

Amine-mediated electrochemical reduction of CO₂ in a nonaqueous, Li-CO₂ battery/
The development of effective CO₂ capture and conversion methods is not only crucial for mitigating rising global atmospheric CO₂ concentrations but also for exploiting atmospheric carbon dioxide as a potential source of C1 feedstock for the industrial synthesis of fuels and chemicals. Herein, we …

Interferences with measurements of CO, CO₂, and O₂ in woodstove flue gases
Concentrations of CO, CO₂, and O₂ in woodstove flue gases are some of the measured inputs required by algorithms used to calculate woodstove efficiency by the stack loss method. Since these algorithms have been shown to be very sensitive to small errors in these input values, it was necessary to …

Strengthening Co-teaching Practices
Co-teaching is a well-known practice utilized by educators when working with specialized or identified learners. Although co-teaching is incredibly common across every school, the potential of co-teaching is often hindered with obstacles that educators are not aware of how to mitigate. The …

Aspects of the reaction of CO and CO₂ with iron oxide-containing slags
A kinetic study of reduction and oxidation slag reactions of importance to the non-ferrous smelting industry was undertaken in the laboratory by employing a thermogravimetry technique. The reduction study included ferrous-to-iron and ferric-to-ferrous reactions whereas a limited amount of data on …
