We study the spatially resolved properties of star-forming galaxies at redshift z ~ 2 - 3 on scales ~ 1 kpc using a combination of morphological and kinematic analyses in an effort to characterize the major mechanisms of galaxy formation in the young universe. Using a sample of 216 galaxies which have been ...

The fragmentation of strategies that distinguishes the more successful elementary grade students from those least successful has been documented previously. This study investigated whether this phenomenon of divergence and fragmentation of strategies would occur among undergraduate students enrolled in a remedial ...

This study describes data that was gathered in 2004 from fieldwork conducted by students from four schools in Singapore, around tasks of wayfinding and debate.

These historical based developments have been segregated into pseudo-cultures and pseudo-traditions in support of political myths utilized to inspire fears and justify regulated legislation and beliefs through ancient myth based ...

One of the major problems encountered in qualitative and quantitative determination of residual pesticides by gas chromatography is the matrix effects. Matrix components have a considerable effect on the way analysis is conducted and the quality of results obtained, introducing problems such as inaccurate ...

Processive enzymes are a special class of enzymes which presumably remain attached to their polymeric substrates between multiple rounds of catalysis. Due to this property, the substrate slides along the enzyme and reduces the time for the random diffusional enzyme-substrate encounters thereby increasing the ...

The dissertation presents the results of a multi-epoch very long baseline interferometric study of water masers located in the extended atmospheres of evolved stars. The research was performed using the Very Long Baseline Array and Very Large Array of the National Radio Astronomy Observatory. Optical monitoring of the ...
