A Method For The Immobilization Of Xanthine Oxidase In Ca-Alginate Membranes To Measure Hypoxanthine Concentration In Order To Assess Flesh Food Quality, Hamad A. Al-Awfy

Open Access Dissertations

The consumer's acceptance of food quality is an important factor, especially in Third World Countries which import much of their food. Since flesh food (meat, fish) is shipped to those countries frozen or in cold storage, it is susceptible to temperature fluctuations during shipment, resulting in deterioration of the meat and unacceptable quality. Therefore an acceptable procedure to assess flesh food quality is necessary to protect the consumer and trader and to aid in the manufacture of high quality food products.

Hypoxanthine concentration in flesh food has been a useful index for the assessment of freshness. Therefore, it was selected …

Biological And Environmental Influences On The Cognitive Development Of Children With Developmental Disabilities, Ruth H. Schennum

Open Access Dissertations

The biological and environmental influences on sensorimotor/cognitive development were studied. Participants were 100 children with developmental disabilities between the ages of 2 and 28 months and their families. Scores from the Rochester Research Obstetric Scale (ROS), Pediatric Complications Scale (PdCS), and Home Observation for the Measurement of the Environment (HOME) were used as independent variables in a multiple regression analysis. The dependent variable was the Mental Development Index (MDI) from the Bayley Scales of Infant Development. Results indicate there is a significant, but moderate relationship between the independent and dependent variables. Very little overlap was found among the independent variables. …

Comparison Of Three Separation Tecnniques For Arsenic (Iii) And Arsenic (V) In Sea Water, Samuel Asare Amankwah

Open Access Dissertations

Separation and determination of arsenic species in sea water is an attractive area of current research primarily due to the effects the different oxidation states of the element have on its bioavailability and toxicity. Many separation procedures for the arsenic species in sea water prior to their determination by graphite furnace -, hydride generation - atomic absorption spectrophotometry or neutron activation technique have been reported.

Evaluation of three of these separation procedures based on (1) solvent extraction, (2) ion-exchange, and (3) thiol cotton is reported in this dissertation. The evaluation is based on the analytical parameters: Detection limits, Sensitivity, Reproducibility, …

Determination Of Retinol By Aqueous Reverse Phase Open Column System, Abdulaly B. Al-Abdulaly

Open Access Dissertations

The AOAC method and other open column techniques which are used to determine retinol content, are time consuming, require technical skills, and do not always result in a complete separation of retinol from other fluorescent components. In some cases cis-trans isomers are formed due to the long term exposure of retinol to oxygen, light, adsorbents and solvents. The colorimetric method hes disadvantages which include a rapidly fading blue color, sensitivity of the reagent to moisture, and interference from carotenoids. The more recently developed HPLC method is rapid, reproducible, nondestructive, quantitative and gives high resolution of closely related compounds. The instrumentation, …

Studies On The Metabolism Of Astaxanthin In The Rainbow Trout (Salmo Gairdneri), Abdulrhaman Salih Al-Khalifah

Open Access Dissertations

Racemic astaxanthin was fed to rainbow trout (Salmo gairdneri) for 2, 4, and 6 weeks. The fish showed a bright pink coloration of the skin and flesh; the highest amount of astaxanthin (162 ug/100g) was found in the skin of fish fed the test diet for six weeks. Lutein, 3-epilutein, and zeaxanthin were also detected in the flesh and skin; it was concluded that astaxanthin was converted to zeaxanthin in the skin. The mean vitamin A content of the liver was determined; the ratio of vitamin A₁: vitamin A₂ was approximately 1:3. There was no …

Anatomical And Morphological Response Of Highbush Blueberry To Flooding Stress, John David Abbott

Open Access Dissertations

The purpose of this research was to study the various aspects of root, shoot and reproductive growth of the cultivated highbush blueberry under normal conditions and as influenced by seasonal root zone flooding.

These studies were conducted on three cultivars – “Earliblue”, “Bluecrop”, and “Lateblue” for up to three years. Root, shoot, and reproductive growth were measured at intervals throughout the years and the soil temperature and stage of plant development recorded.

Growth of white unsuberized roots peaked in early-June and September when soil temperatures were in the range of 14 to 18 °C and was concomitant with shoot growth. …
