Honey Amylase And The Effect In Starch-Containing Foods, Sibel Babacan
Honey Amylase And The Effect In Starch-Containing Foods, Sibel Babacan
Open Access Dissertations
Honey amylase was evaluated for potential to degrade food starch and cause viscosity loss. Honey was assayed for amylase activity with diastase number (DN). A viscosity assay, developed with unmodified waxy maize starch, measured rate of viscosity decrease (RVD) by honey amylase. The relationship between DN and RVD was linear (R2 = 0.98). Modified waxy maize starches showed resistance to honey amylase. Heat treatment at 85 °C reduced the amylase activity in honey, but confirmed enzyme heat resistance. Optimum pH for honey amylase was confirmed at pH 5.3-5.6. Lower pH was effective at decreasing enzyme activity in both pure starch …

A Synthetic Approach To Forecasting Fleet Costs And Earnings In The Northeast Regions Of The United States, Philippe D. Lallemand
Open Access Dissertations
This study describes the New England Otter Trawl Fishery between 1982 and 1998 and the potential economic impacts of regulations on the Northeastern Multispecies Groundfish Fishery (MGF). The study uses primary data collected by the author and secondary data obtained from the National Marine Fisheries Service (NMFS). This research required extensive econometric analysis of both value landed and cost data. The landed value is influenced by the vessel's physical characteristics, port of landing, seasonal choices of fishing gear-species combinations, days at sea and distance from shore, and the captain's skill (also referred to as the "skipper effect"). The vessel-cost model …

Physicochemical And Microstructural Changes In Minced Fish Muscles As Affected By Cryoprotectants, Peizhi Lian
Open Access Dissertations
Alginate, carrageenan, soy protein concentrate (SPC), sodium tripolyphosphate (STPP), and sorbitol were chosen as potential cryoprotectants. Their effects on physicochemical and sensory properties of frozen red hake (Urophycis chuss) and Alaska pollock (Theragra chalcogramma ) mince at ˆ’20 °C for 17 weeks were investigated. The mince was mixed with 0.3% STPP, 4% sorbitol and either 0.2-0.4% alginate, 0.2-0.4% iota-carrageenan, or 4% SPC. Changes in texture, microstructure, and profiles of proteins, free amino acids and lipids of fresh and frozen mince were evaluated. The addition of alginate, STPP, and sorbitol significantly improved the dispersibility of uncooked red hake mince with reduced …

Are Iq Discrepancies Between Ses Groups Primarily The Result Of Verbal Scale Differences?, Carol Lee Macnaught
Are Iq Discrepancies Between Ses Groups Primarily The Result Of Verbal Scale Differences?, Carol Lee Macnaught
Open Access Dissertations
Historically, comparison groups of children from low socioeconomic status (SES) have done less well on intelligence tests than their more well-to-do counterparts. This study was undertaken to explore the contribution of verbal ability to general intelligence and to consider the possibility of developmental change in the relative contributions of the verbal and performance scales. The analyses used verbal, performance, and full scale scores of a subgroup of the standardization sample of the Wechsler Intelligence Scale for Children - Third Edition (WISC-III). The scores used were attained by children in three age groups (7, 11, and 15 years) with four levels …

This study examined the relationship between at-birth risk factors and three year child developmental outcome. The purpose of this study was to design a multifactor risk screening system to identify those children who are at risk for developmental delay and behavior problems in Rhode Island. The sample was drawn from three separate datasets: the Rhode Island Universal Newborn Screening (Level One) database (N=27,282), the Early Intervention (El) database (N=l ,793), and the Maternal Lifestyle Study Providence/Teen samples (N= 311). Study One investigated the predictive probability of Level One for EI eligibility by age three. Results showed that Level One has …
Maintaining Behavioral Changes: A Descriptive Account From Individuals With Type 2 Diabetes, Rosemary Fedrigon Hall
Maintaining Behavioral Changes: A Descriptive Account From Individuals With Type 2 Diabetes, Rosemary Fedrigon Hall
Open Access Dissertations
Type 2 diabetes is a serious metabolic disorder occurring in over 90% of the people in the United States diagnosed with diabetes. The standard treatment for type 2 diabetes requires individuals to self-manage a diet, exercise, and self-monitoring of blood glucose (SMBG) to control blood glucose levels and reduce the onset of serious complications. Although there is a plethora of literature addressing the difficulty individuals have to maintain these three behaviors, few studies exist describing how these behaviors are sustained. This descriptive qualitative study was designed to learn how individuals with type 2 diabetes maintained behavioral changes of diet, exercise, …

Blood Glucose Estimation Accuracy In Children With Diabetes: An Investigation Of Repeated Practice With Latent Growth Curve Modeling, Julie Ann Wagner
Blood Glucose Estimation Accuracy In Children With Diabetes: An Investigation Of Repeated Practice With Latent Growth Curve Modeling, Julie Ann Wagner
Open Access Dissertations
Blood glucose (BG) estimation is an important part of maintaining euglycemia in individuals with diabetes. Interventions to increase accuracy were designed without taking into account the natural effects of practice. The current study investigated the effects of naturalistic practice on BG estimation accuracy. Latent growth curve modeling (LGCM) was used to analyze data from 43 children with insulin dependent diabetes. LGCM consists of two stages. In the first stage, a growth curve was fit to the repeated measures of each individual in the sample. Results indicated that the true growth trajectory was curvilinear, and best represented by a quadratic function. …

Development, Characterization And Evaluation Of A Pulsed-Release Tablet Dosage Form For Low Dose Water Soluble Drugs, Suresh Palaniswamy
Open Access Dissertations
Various types of controlled release dosage forms such as wax matrix hydrophilic polymer matrix, osmotic pump and acrylic resin polymer encapsulated slow release for water soluble drugs have been developed and reported. However, there was no significant information available in the literature about the development and scale-up of pulse-release tablet dosage form for low dose water soluble drugs. This investigation was undertaken to develop, characterize and evaluate a new pulsed-release dosage form for a low dose water soluble drug with consistent drug release that combines polymer matrix and aqueous coating technology. The effect of scale-up on granulation, compression and coating …

The Development, Characterization And Evaluation Of A Novel Multi-Unit Eroding Matrix System For Poorly Soluble Drugs, Ketan Arvind Mehta
The Development, Characterization And Evaluation Of A Novel Multi-Unit Eroding Matrix System For Poorly Soluble Drugs, Ketan Arvind Mehta
Open Access Dissertations
Mechanisms governing the release of drugs from controlled delivery systems are mainly diffusion, osmosis and erosion. For poorly soluble drugs, the existing mechanisms are limited to osmosis and/or matrix erosion. These mechanisms are commonly employed to control drug release from single unit and multi-unit dosage forms. More recently, multiunit dosage forms have gained considerable popularity for controlled release technology due to their advantages over single unit dosage forms. However, the mechanism of polymer controlled surface erosion from a multi-unit dosage form has never been reported in the literature. This study describes the development, characterization and evaluation of a matrix pellet …
