Nutrient And Phosphorus Geochemistry In The Taunton River Estuary, Massachusetts, Joceline M. Boucher Jan 1991

Nutrient And Phosphorus Geochemistry In The Taunton River Estuary, Massachusetts, Joceline M. Boucher

Open Access Dissertations

Mineral equilibria and sorption reactions are often invoked as mechanisms that regulate the concentration of nutrient phosphorus (P) in estuaries, and are sometimes termed collectively as the "phosphate buffer". However, the estuarine chemistry of P is only partly known and from theory alone it is not possible to predict the reactions that occur in a particular estuary. The objective of the present study is to quantify the sorption of P on particles transported through an estuarine salinity gradient, and to evaluate the importance of sorption processes in the seasonal nutrient chemistry of the estuary.

Regionally important but largely unstudied, the …

Development Of High Performance Liquid Chromatographic Separations For The Purification And Analysis Of Phospholipids And Related Liponucleotides - A New Class Of Anti-Aids Drugs, John V. Amari Jan 1991

Development Of High Performance Liquid Chromatographic Separations For The Purification And Analysis Of Phospholipids And Related Liponucleotides - A New Class Of Anti-Aids Drugs, John V. Amari

Open Access Dissertations

High performance developed to isolate phospholipids and liquid chromatographic methods were and purify naturally occurring synthetic experimental Anti-AIDS liponucleotides on a preparative scale. Separations were optimized on packed with an analytical size method development column, the same media used in the preparative separations. A phospholipid class separation, on a silica stationary phase, was developed for the isolation of lecithin in chicken egg yolk. The collected fractions were analyzed for purity by analytical HPLC with UV and light scattering detection. Liponucleotides have been synthesized and required HPLC for purification. The methodology was based upon conventional phospholipid species separations on reversed-phase supports. …


Experientially-Modulated Neuronal Death In Overconnected Neural Networks, Thomas J. Skrmetti Jan 1991

Experientially-Modulated Neuronal Death In Overconnected Neural Networks, Thomas J. Skrmetti

Open Access Dissertations

This experiment was designed to examine the possible physiological mechanisms underlying the formation of critical periods in development. It was hypothesized that experientially-modulated neuronal death, coupled with an overconnected neural network, and acting early in the developmental sequence, could produce a learning effect similar to that described as a "critical period effect."

A computer-based associative memory model was used to simulate a simple neural network representing the associative cortex. Three different independent variables were manipulated in the experiment. The first was the type of connectivity matrix used when the model was initialized prior to training.

Four different developmental paradigms were …


The Physical Chemistry Of Atmospheric Iron And Its Geochemical Behavior In The Surface Waters Of The Open Ocean, Guoshun Zhuang Jan 1991

The Physical Chemistry Of Atmospheric Iron And Its Geochemical Behavior In The Surface Waters Of The Open Ocean, Guoshun Zhuang

Open Access Dissertations

The physical chemistry of atmospheric iron present in remote marine aerosols collected from over the North Pacific has been systematically studied. 90- 100% of iron present in remote marine aerosols is in the non-aluminosilicate form. The Fe(II) concentrations in remote marine aerosols has been determined for the first time, and more than 50% of the iron is present as Fe(II). Photochemical reduction, including sulfur or organic reductants, and the subsequent dissolution of iron are probably the dominant transformation mechanisms affecting atmospheric iron during its long range transport from Asia to the North Pacific. It is postulated that the key reaction …


Optimization Of Ibuprofen Formulation: Molecular Pharmaceutics Of The Biologically Active Stereoisomer, Alain Joseph Romero Jan 1991

Optimization Of Ibuprofen Formulation: Molecular Pharmaceutics Of The Biologically Active Stereoisomer, Alain Joseph Romero

Open Access Dissertations

A program of experiments comparing the formulation of rac-ibuprofen to that of (-)-S-ibuprofen was performed. Early investigations revealed that although complying with the United States Pharmacopeia compendial standards five different sources of rac-ibuprofen had different processing characteristics and as a result variable biopharmaceutical properties. Crystal habits critically influenced processing parameters. It was possible to identify low and high liquid requirement powders for the wet granulation end- point. Further analysis of rac-ibuprofen crystals was performed during the different stages of tablet manufacture. Phase diagrams confirmed that rac-ibuprofen crystallizes preferentially in the monoclinic space P21 c group as a true racemate. It …

Accumulation, Persistence, And Elimination Of Microbial Indicators By Molluscan Shellfish, William Burkhardt Iii Jan 1991

Accumulation, Persistence, And Elimination Of Microbial Indicators By Molluscan Shellfish, William Burkhardt Iii

Open Access Dissertations

The accumulation of fecal coliforms and several other indicator microorganisms (Escherichia coli, enterococci, Clostridium perfringens, and male-specific bacteriophage) by hard-shelled clams (Mercenaria mercenaria) was investigated with regard to season and temperature. Very high rates of accumulation were found for each of these indicator organisms during distinct periods in the spring. Uptake of indicators during these periods exceeded 2 SD of the mean annual accumulation rates. Except for these periods of 'hyper-accumulation', uptake of the indicators is at least partially temperature dependent. In general, bacteriophage and C. perfringens were accumulated by clams at significantly higher rates …
