Wheyruit slush formulas were evaluated prior to consumer testing of pre-selected formulated beverages. Varying ingredients were prepared in accordance to a factorial design of maximum use of whey and minimum use of additional ingredients. Whey was obtained from the Mississippi State University Dairy Processing Plant and evaporated. The evaporated sweet whey was combined with blueberries, cherry concentrate, Splenda®, water and ice. Sensory tests were conducted to evaluate appearance, flavor and overall acceptability of formulations. Panelists were asked to participate in a survey to elaborate personal perceptions of the products. Formulation of 125mL whey and 30g blueberries had the higher acceptability score, but was not different from the beverage with 150mL whey and 30g blueberries. These two formulas were tested for chemical analysis. Adequate levels of antioxidants, total phenolics and neutral pH were observed. Results from proximate analysis showed minimal caloric levels with low presence of protein and carbohydrate.

<p> The deposition parameters of thin vacuum-evaporated films were studied in the development of thin-film devices. These devices, including resistors, diodes and transistors, were constructed by the use of vacuum deposition techniques and metal masks for pattern generation.</p> <p> Stable thin-film resistors were fabricated using nichrome as the resistance material. The variation of resistance value with both temperature and time was investigated.</p> <p> A metal-cadmium sulphide-metal structure was employed as a thin-film diode, the electrodes being of aluminium or gold. The electrical evaluation of such a device demonstrated the importance of the deposition of the semiconductor on the rectifying properties. Forward to reverse resistance ratios of 10^5 were observed for experimental units.</p> <p> The staggered-electrode structure was incorporated in the production of thin-film transistors. Cadmium sulphide was used as the semiconducting material while silicon monoxide and aluminium were used as the insulator and electrodes respectively. Operating devices exhibiting good saturation characteristics has transconductances of 450μ mhos. Simple circuits were constructed to demonstrate the performance of thin-film transistors.

<p> The analysis, construction and performance of a new type of evaporated thin-film filter is described. It has the capability of frequency tuning by means of a single bias voltage.</p> <p> The device is basically a uniformly distributed resistance-capacitance network (URC) with a thin semiconductor film incorporated in the structure. The resistive film, insulator and semiconductor films constitute a metal-insulator-semiconductor system (MIS) whose capacitance is bias dependent. The device differs from other proposed tunable thin-film filters in the fact that the capacitance can be altered independently of the distributed resistance.</p> <p> A theory is developed to account for the effects of MIS-losses and parasitic inductance on the performance of URC-null networks. These parasitic effects manifest themselves in four different ways: (i) A shift of the null from the position predicted by the ideal theory. (ii) A change in the notch parameter α for an optimum null. (iii) A detuning effect in the case of tunable notch filters. (iv) A reduction in the available tuning range; the so-called "tuning range compression".</p> <p> Experimental units were made by vacuum evaporation of Nichrome, Y2O3, CdS and Al onto alumina substrates. An attempt is made to relate the device characteristics to the material properties. In this respect, the relative dielectric permittivity and thickness of the insulator, the doping density of the semiconductor, the semiconductor-insulator interface states and the bulk states in the semiconductor are found to be the most important parameters.</p> <p> Filters were built which operated in the frequency range 600 kHz to 6 MHz. The best notch filter has a tuning capability of 30% with a ±15V bias voltage. The notch depth is over 60 dB in most cases. A tunable bandpass amplifier which was constructed, has a centre frequency which can be shifted between 6 MHz and 7 MHz with a ±3.5V bias voltage. The Q of this particular device was measured to be 742.</p> / Thesis / Doctor of Philosophy (PhD)
