Effect Of Temperature And Packaging Material On Vitamin A And Riboflavin In Milk, Abdulaziz Ahmed Al-Zawawi

Open Access Master's Theses

The effect of different heating times and temperatures and packaging on vitamin A and riboflavin retention was studied in whole and skim milk. Refrigerated storage (40C) in the dark for 15 days resulted in losses of vitamin A ranging from 9-12% in pasteurized whole milk, and 14% in pasteurized skim milk fortified with vitamins A and D. Riboflavin losses did not exceed 8 % • Vitamin A was also more labile than riboflavin when stored at room temperature ( 230C) • ' Vitamin A was retained better in whole milk than in skim milk where there was no protection from …

Population Characteristics And Sulfide Oxidizing Metabolism Of The Bivalve Solemya Velum, Chong Chen

Open Access Master's Theses

The physiological and biochemical studies of some animals from sulfide-rich habitats, such as deep sea hydrothermal vents, sewage outfall areas, eelgrass beds and mangrove swamps, have shown that sulfide-oxidizing chemoautotrophic bacteria exist endosymbiotically with the animals and provide a major energy source to their host. One of the remaining questions is the degree to which the symbiont supplies the host's need for reduced carbon and energy metabolism.

Solemya velum, a common Atlantic clam from Nova Scotia to Florida, has chemoautotrophic symbionts in the gill tissue (Cavanaugh, 1983). The host animal has a reduced digestive system and lacks some digestive …

Effect Of Fecal Pollution On Vibrio Parahaemolyticus Densities In An Estuarine Environment, W. D. Watkins, Victor J. Cabelli

Past Departments Faculty Publications (CELS)

Vibrio parahaemolyticus densities in the Narragansett Bay, R.I., estuary were found to significantly correlate with the level of fecal pollution in the water. Results of field investigations showed a definite association between the levels of this organism and those of Escherichia coli, Clostridium perfringens, and enterococci. Densities of V. parahaemolyticus were greatest in the near-surface waters of contaminated areas and decreased sharply with both the distance from the sources of fecal pollution and the depth of the water column. A positive association with the amount of particulate matter in the water and specifically with its zooplankton content also …

Detection, Enumeration, And Sizing Of Planktonic Bacteria By Image-Analyzed Epifluorescence Microscopy, Michael E. Sieracki, Paul W. Johnson, John Mcn. Sieburth

Graduate School of Oceanography Faculty Publications

Epifluorescence microscopy is now being widely used to characterize planktonic procaryote populations. The tedium and subjectivity of visual enumeration and sizing have been largely alleviated by our use of an image analysis system consisting of a modified Artek 810 image analyzer and an Olympus BHT-F epifluorescence microscope. This system digitizes the video image of autofluorescing or fluorochrome-stained cells in a microscope field. The digitized image can then be stored, edited, and analyzed for total count or individual cell size and shape parameters. Results can be printed as raw data, statistical summaries, or histograms. By using a stain concentration of 5 …

Factors Influencing Food Habits In Antigua, W.I., Jill E. Armstrong

Open Access Dissertations

A cross-cultural food habit model constructed after review of available literature was used as a guide for investigating food habit determinants. A food habit survey was conducted in Antigua, W.I. in December, 1981 and January, 1982 to test the model. Data collected by questionnaire from 305 households included household food purchase and production, food consumption via 24-hour recall and food frequency, food-related beliefs and socioeconomic characteristics of respondents and household members. Results showed that the Antiguan diet is starch-based and that, despite crop production by about two-thirds of the households sampled, many diets appeared to be deficient in selected fruit …

Benthic-Pelagic Coupling And Nutrient Cycling Across An Experimental Eutophication Gradient, John R. Kelly, Veronica M. Berounsky, Scott W. Nixon, Candace A. Oviatt

Graduate School of Oceanography Faculty Publications

Sediment-water exchange rates of dissolved inorganic nitrogen (NH₄⁺, NO₃^-, NO₂^-) and

phosphorus (PO³₄^-), water column concentrations of both dissolved and particulate forms of N and P, and net primary production (¹⁴C) were measured during a summer period in large (13 m³) experimental mesocosms that had been subjected to continuous daily nutrient additions (N, P, Si) for over 1 yr. The concentration of combined dissolved inorganic plus particulate nutrient forms (N, P) was linearly related to the nutrient input rate across a loading range …

Cycle Of Changing Abundances In The Fishes Of The Narragansett Bay Area, Harry Perry Jeffries, Mark Terceiro

Graduate School of Oceanography Faculty Publications

Winter flounder Pseudopleuronectes americanus in Narragansett Bay, Rhode Island reached peak abundance in 1968 and then went into an 8 yr decline, dropping to 1/7 of its former population size, as estimated form weekly tows by otter trawl. Meanwhile a succession of species increased offshore: red hake Urophycis chuss became the commercial dominant in 1973, the ocean pout Macrozoarces americanus and silver hake Merluccius bilinearis in 1974, but among these coastal migrants only scup Stenotomus chrysops entered the bay in substantial numbers. By 1976 scup had increased 25 times in the bay, numerically overshadowing the flounder’s 8 yr decline. A …

The Effects Of Regulation On Aquaculture Development, Derek S. Busby

Marine Affairs Theses and Major Papers

A comparative study of the regulatory frameworks surrounding aquaculture in the states of Florida, Mississippi, and Rhode Island is conducted beginning with a generalized study of basic legal premises of aquaculture-related law common to each state. This is followed by a detailed study of the statutory authority for aquaculture regulation and the agencies which control aquaculture activities in each state. In conjunction with the law analysis an Index of Specialization (ISP) study is conducted for each state to determine a relative ranking of diversity of crop production relative to each state’s overall aquaculture production.

Marine Resources: The Presentation Of A Business Plan, K. Scott Colby

Marine Affairs Theses and Major Papers

The once questionable technology of hatchery production has become routine and, with the recent development of up-welling techniques, is more effective and efficient. The supply of natural shellfish and fishery stocks is on the decline and this trend is expected to continue. Aquaculture has been the solution to this problem in many European countries and the United States is currently attempting to remove domestic obstacles through its National Aquaculture Plan. The proprietor has experience in the production of various marine invertebrates and has designed, built and operated a producing shellfish hatchery. By using a unique up-welling juvenile culture system a …
