Chromatographic Methods Development For The Charcterization Of Phytopharaceutical Materials, Melanie Levesque

Theses

The increased popularity of alternative medicine treatments has prompted resurgence in the use of traditional herbal remedies. Among this vast number of herbs, ginseng is purchased by a considerable number of consumers; especially three species: Panax ginseng, Panax quinquefolium, and Eleutherococcus senticosus. Many of the physiological effects claimed by ginseng manufacturers tend to mimic those of central nervous system stimulants. This led to the purpose of this research, which was to develop an HPLC chromatographic method in order to determine if any specific CNS stimulants are within ginseng supplements. Specifically we found a series of CNS stimulants, methylxanthines (caffeine, theophylline, …

Chinese Characters As Sources Of Design Of Furniture, Han-Lim Wee

Theses

This thesis is an exploration of possibilities of the translation of Chinese characters into furniture. It is not just the two dimensional image of the character that I wish to interpret into three dimensions, but I intend that the functions and uses of the furniture are to be the meaning of the word. The final pieces are intended to be recognized as to their meaning by anyone literate in Chinese character forms. Furniture that has both form and meaning will create new possibilities for furniture's role in the environment by having this extra dimension.

Molecular & Physical Characterization Of Threonine Dehydrogenase From Serratia Marcescens, Michael Wetherell

Theses

Threonine dehydrogenase has been purified from Serretia marcescens 450 fold to obtain 1300 micrograms of enzyme from 15 grams of cells. The amino-terminus has been sequenced and places it in a class with medium chain alcohol dehydrogenases from both Z.mobilus and E.coli. The native enzyme is a dimer of 35.6 kD sub-units containing approximately 324 amino acids. The gene structure of the enzyme is dissimilar from that of the E.coli TDH and may represent a mutation of an alcohol dehydrogenase with possible preference to propanol.

Discrete-Time Continuous-Dilation Construction Of Linear Scale-Invariant Systems And Multi-Dimensional Self-Similar Signals, Wei Zhao

Theses

This dissertation presents novel models for purely discrete-time self-similar processes and scale- invariant systems. The results developed are based on the definition of a discrete-time scaling (dilation) operation through a mapping between discrete and continuous frequencies. It is shown that it is possible to have continuous scaling factors through this operation even though the signal itself is discrete-time. Both deterministic and stochastic discrete-time self-similar signals are studied. Conditions of existence for self-similar signals are provided. Construction of discrete-time linear scale-invariant (LSI) systems and white noise driven models of self-similar stochastic processes are discussed. It is shown that unlike continuous-time self-similar …

Measurement Of The Baroreceptor Sensitivity Index (Brsi) In The Frequency Domains, Tanvir Raquib

Theses

Time domain analysis for calculating the Baroreceptor Sensitivity Index (BRSI) did not always provide an accurate result. It also had another limitation in that it could not show the influence of the autonomic nervous system for different subjects. The correlation coefficient is a mechanism that was used to either accept or reject the BRSI values in the time domain but the correlation coefficient values changed drastically depending on how many sample points were selected for the calculation.

On the other hand, frequency domain analysis for the BRSI calculation was relatively easier and provided more accurate information compared to the time …

Implementation Of A Geometric Hashing Technique And It's Application To 3d Molecular Structure Search, Jennifer Lynn Cerequas

Theses

This paper proposes the application of a geometric hash technique to the searching of 3D chemical structures. Chemical structures are represented in global XYZ coordinate format. An algorithm is applied to the substructures within the existing chemical structures to hash them into hash tables on disk. A query substructure is then hashed to find matches (hits) of the existing hash tables. The entries in the matching hash tables are compared to the query substructure to find the existing substructures that are an "approximate" match.

The result is a technique which allows existing substructures to be compared to a (new) query …

Mathematical Model Of Human Sit-To-Stand And Stand-To-Sit Motion Analysis, Jayeshkumar Gandhi

Theses

In designing a device for an amputee, it is important to find those underlying principles which determine the normal human sit-to-stand task. For this purpose we have developed a mathematical model of human sit-to-stand movement, which it is possible to predict the minimum mechanical energy consumption to move from the sit-to-stand position.

To the best of author's knowledge, this thesis represents the first time that the periodic motion of stand-to-sit and sit-to-stand movements have been mathematically modeled by a simple mechanical system.

The samples were cut into 3 X 3 mm2 washed in phosphate buffered saline solution, transferred into cell culture flask containing cells that had been cultured for 24 hours and incubated at 37 "C in 5 % CO2. …

A Microcosm Study In The Reductive Dechlorination Of Tetrachloroethylene Using Fermentation Acids And Alcohols As Electron Donors, Anthony Siccard Iii

Theses

Anaerobic microcosms of Arthur Kill (New Jersey) sediment were used to investigate the effects of several electron donors on tetrachloroethylene (PCE) dechlorination activity. The substates tested were methanol, butanol, butyrate, lactate and succinate both by themselves and in various combinations. Different levels of PCE dehalogenation were noticed in all of the microcosms regardless of the electron donor used. Vinyl chloride was the major dehalogenation product detected in the majority of the microcosms. The causitive organism or group that carried our the reductive dehalogenation was not identified. Only the microcosms admended with a mixture of butanol/methanol were able to fully reduce …

Investigation Of Pathophysiologic Trends In Caucasian And Afro-American Hypertensives By Means Of Heart Rate Variability Recording During Upright Tilt-Table Testing, Jose F. Torrealba

Theses

The incidence of hypertension is more prevalent among the Afro-American population than the Caucasians and there is not a satisfactory explanation for this discrepancy.

Heart Rate Variability (HRV) has been demonstrated to reflect the relative activities of the sympathetic (SMP) and parasympathetic (PSMP) divisions of the autonomic nervous system (ANS).

This study consisted in comparing the HRV, as well as the blood pressure (BP) of four different groups during up-right tilt table testing. The subjects were grouped by age, gender, race and health condition. Analysis in time and frequency domain was applied to the data. In the frequency domain, the …

Coarse-Grained Parallel Genetic Algorithms: Three Implementations And Their Analysis, Daniel Pedersen

Theses

Although solutions to many problems can be found using direct analytical methods such as those calculus provides, many problems simply are too large or too difficult to solve using traditional techniques. Genetic algorithms provide an indirect approach to solving those problems. A genetic algorithm applies biological genetic procedures and principles to a randomly generated collection of potential solutions. The result is the evolution of new and better solutions. Coarse-Grained Parallel Genetic Algorithms extend the basic genetic algorithm by introducing genetic isolation and distribution of the problem domain. This thesis compares the capabilities of a serial genetic algorithm and three coarse-grained …
