HPLC analysis of salicyluric acid as a marker of low dose aspirin consumption
Background . A low dose aspirin regimen (81 mg/day) is now commonly prescribed for the prevention of occlusive cardiovascular disease in both symptomatic and asymptomatic patients and for patients suffering from chronic ...
Nanostructured photovoltaic devices for next generation solar cell
As the search for alternative sources of energy other than petroleum continues to expand, solar energy conversion has already been identified as one of the most promising technologies. In the past few years there has been ...
Systematic analysis of the scatter environment in clinical intra-operative high dose rate (IOHDR) brachytherapy
Most brachytherapy planning systems are based on a dose calculation algorithm that assumes an infinite scatter environment surrounding the target volume and applicator. In intra-operative high dose rate brachytherapy (IOHDR) ...
Enhancement of the low frequency sound absorption of porous materials by addition of a thin high flow-resistivity cover layer
The general performance of a porous material against a rigid backing shows very good absorption qualities at high frequencies, but at lower frequencies, where the thickness becomes much less than a wavelength of sound, the ...
Robust microbial fabrication of plant pharmaceuticals: Complexities and solutions
Abstract not available.
Spin injection studies from ferromagnetic contacts into indium arsenide quantum dots
Spintronics or spin electronics has been one of the most rapidly developing research areas in condensed matter physics. Exploiting the electron's spin degree of freedom in addition to its charge is hoped to yield new and ...
Probing metal binding sites in DNA by using europium(III) luminescence spectroscopy
Metal ion binding sites in nucleic acids are difficult to locate and characterize; NMR spectroscopy and X-ray crystallography are the two most widely used methods. Lanthanide luminescence is a third promising technique ...
The dynamical transition of myoglobin for low hydrations studied with terahertz time domain spectroscopy
Terahertz time domain spectroscopy was performed to determine the temperature dependence of metmyoglobin in the range of 80-265K for different hydrations. Metmyoglobin in solution and ground powder was used. A procedure ...
The role of DNA replication in mismatch repair
DNA Mismatch Repair (MMR) plays an important role in maintaining genomic fidelity and stability in all living organisms, ranging from bacteria to humans, and is known to be closely associated with DNA replication and present ...
A study of polymer tertiary structure in Langmuir monolayer films of poly(dimethyl siloxane) by time-of-flight secondary ion mass spectrometry, reflection-absorption Fourier transform infrared spectroscopy and high-resolution electron energy loss spectroscopy
The primary focus of this thesis is development of vibrational spectroscopy and the use of time of flight secondary ion mass spectrometry (ToF-SIMS) to identify surface tertiary structures of macromolecules. For this ...
