Novel approaches to enhancing selectivity and efficiency in microscale liquid chromatography

Creator:: Vallano, Patrick T.
Abstract:: For a number of reasons, miniaturization of chromatographic columns has been a general trend over the past three decades. Methods designed to enhance selectivity and efficiency can offer improved separation power and speed, expanding on the advantages of miniaturized columns. This dissertation describes novel approaches in this direction, focusing on...

Novel monolithic columns for microscale liquid chromatography and capillary electrochromatography

Creator:: Chirica, Gabriela S.
Abstract:: The challenges prompted by miniaturization of chromatographic systems have led scientists to explore new avenues in the synthesis of stationary phases. Packed capillary columns have found limited application in routine analysis due to a number of technical difficulties, most of which are attributable to the frits. New column designs insure...

Influence of cultivar and maturity on blackberry polyphenolics and investigation of sediment formation in blackberry juice

Creator:: Siriwoharn, Thanyaporn
Abstract:: The influence of cultivar and maturity on polyphenolic composition and antioxidant activity was investigated by UV-Visible spectrophotometry and analytical high performance liquid chromatography (HPLC) in commercially important blackberry cultivars and selections. The anthocyanin pigments changed tremendously with ripening. Total anthocyanins increased from 74.7-317 mg/100g fw from underripe to over ripe...

Synthesis, characterization and deposition of dendrimers using a continuous flow microreactor

Creator:: Liu, Shuhong
Abstract:: Dendrimers are nanoscale macromolecules that have highly branched, core-shell structures. Higher generation dendrimers have close-packed peripheral functional groups and a hollow interior. The chemistry of the core and the terminal functionalities can be tailored according to the specific application. These structural characteristics provide room for the design of dendrimers to...

Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:: Gregory, Stanley Vincent
Abstract:: Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

Characteristics of NADPH-cytochrome P-450 reductase in the house fly (Musca domestica, L.) and the blow fly (Phormia regina, Meigen)

Creator:: Vincent, Daniel R.
Abstract:: NADPH-cytochrome P-450 reductase, an important enzyme in the cytochrome P-450-dependent microsomal monooxygenase system, was purified from insecticide-resistant (R) and -susceptible (S) house flies (Musca domestica, L.) and from the black blow fly (Phormia regina, Weigen). Proteolytic degradation to a P-450 - inactive form of the reductase was reduced during the...

Comparative study of aerobic and nitrate respiration in Pseudomonas stutzeri

Creator:: Mayeux, Jerry Vincent
Abstract:: Some forms of bacterial respiration do not involve molecular oxygen but instead utilize other hydrogen acceptors for oxidation of the substrate. Various organic and inorganic acceptors may be used. In the present study, the inorganic radicals, nitrate and nitrite, were investigated. Preliminary evidence indicated that nitrate and oxygen are able...

A revision of the genus Deraeocoris Kirschbaum (Heteroptera:Miridae) from western America north of Mexico

Creator:: Razafimahatratra, Vincent de Paul
Abstract:: The genus Deraeocoris Kirschbaum of western America north of Mexico was revised. Approximately 10,000 specimens from the Nearctic Region were examined. Taxonomic characters used by previous authors were reevaluated. In addition to the male parameres, the male vesica and the female posterior wall of the bursa copulatrix and sclerotized rings...
