Abstract:

The 2005 Dietary Guidelines for Americans recommend that Americans consume at least three servings of whole grain foods per day to reduce the risk of chronic disease and to help with weight maintenance. However, most Americans fall short of this recommendation. To reduce the prevalence of chronic disease, overweight, and obesity, health educators should promote healthy behaviors at young ages. The purpose of this study was to measure whole grain intake in college students and to determine its association with body mass index (BMI), a measure of overweight and obesity.

Abstract:

This thesis presents information on the subcellular localisation of two important trace elements, selenium and arsenic, in wheat, rice and rice roots for what is believed to be the first time. The general aim of this work was to illustrate the potential of using physical science techniques to solve biological problems. High resolution secondary ion mass spectrometry was undertaken using the CAMECA NanoSIMS50 with a sensitivity down to ppm concentrations and a lateral resolution of less than 100 nm. Selenium in wheat grain was found to be distributed across both the bran layer and the endosperm

Thesis (MSc Food Sc)--Stellenbosch University, 2004.<br>ENGLISH ABSTRACT: Kefir is a fermented dairy beverage resulting from the fermentation of milk with reusable Kefir grains. The grains consist of a complex combination of lactic acid bacteria and yeasts in a symbiotic relationship, embedded in a polysaccharide matrix called kefiran. Various problems are experienced during the commercialisation of the ready-made Kefir beverage and, therefore, it is more advantageous to market the grains, enabling the consumer to produce the beverage at home. Kefir grains could be mass-cultured and then

Aim. In this project, theoretical models of dust driven winds of asymptotic giant branch (AGB) stars with effective temperatures within a range of 2400 − 3200 [K] and relative carbon-to-oxygen abundance C/O > 1 are studied. The aim is to understand if and how a detailed description of the grain size in winds of carbon rich AGB stars affects the wind formation and wind driving processes. Method. The computations were performed with a well tested FORTRAN code by calculating a grid of 60 models with different stellar parameters using grain size-dependent opacities.

Abstract:

Barley (Hordeum vulgare L.) is one of the earliest domesticated cereal crops. It is used in world malt barley production, where Australia is a major exporter, representing more than 30 per cent of the world's trade. Barley is the grain of choice for malt production due to its high starch-to-protein ratio and enzyme levels that can be harnessed during germination. Malt is produced by a process called malting, which involves a three-stage controlled germination of malting barley grain. This process uses enzyme activation and de novo enzyme synthesis to modify the physical structure of the hard b

Abstract:

Barley (Hordeum vulgare L.) is the fourth largest produced cereal worldwide. About two thirds of barley production is used to animal feed. When used to feed monogastric animals, the main shortcoming of barley grains is the deficiency of essential amino acids, especially lysine, threonine and methionine. The unbalanced amino acid composition is due to the main storage protein, the hordeins, which account for about 50% of total grain protein content. The nitrogen fertilization promotes C-hordein expression and accumulation, the hordein subgroup with the lowest content of essential amino acids, a

Abstract:

In general, yield reduction in most dryland maize growing areas of South Africa occur because seasonal rainfall distribution is erratic with annual variation that cannot be predicted accurately. Cultivar selection, planting date and plant density are other factors that consistently affect maize yield. Long growing season maize cultivars are higher yielding, particularly under conditions of good moisture and nutrient supply. However, as both moisture and nutrient availability becomes more limiting, yield tends to decline. Short growing season maize cultivars could yield more than long season co

Abstract:

Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. In this thesis, we modified the pressure-less spark plasma sintering set-up to generate intense thermal radiation, aiming at rapid consolidation of ceramic bulk materials. This approach was named as “Sintering by Intense Thermal Radiation (SITR)” as only therm

Currently, there is tremendous interest in using block copolymers to generate nanostructures where a critical issue is the control of long range order.

Using a series of AnBn star block copolymers with different numbers of arms (n = 1, 2, 4 and 16), the effect of molecular architecture on the grain growth kinetics is investigated by both thermal annealing and annealing in supercritical carbon dioxide (CO 2).
