A voltage reference is an essential building block of many analog and digital circuits. The performance of a reference is gauged by the maximum variation in its allowable operating conditions. One of the most important specifications of a reference is its temperature drift. Therefore, special attention should be paid by the designer to the thermal behavior of a voltage reference. In this thesis...

Red pine cone and barks combined with red pine wood particles in various proportions were used as the raw materials for one and three layered experimental particleboard manufacturing in laboratory conditions. The pine cones and barks have higher lignin, but lower holocellulose content compare to wood. For bark-based panels, the highest MOR (2.52 MPa) corresponded to the lowest thickness swellin...

Peanut seeds were prepared with variations in roasting conditions. Positive correlations were obtained between loss of aflatoxins in the products and the roasting conditions. Seeds dryroasted at 140C for 40 min resulted in 58.8% and 64.5% reductions in AFB1 and AFG1, those roasted at 150C for 25 minutes resulted in 68.5% and 73.3% reductions in AFB1 and AFG1, respectively. Roasting at150C for 3...

Nanostructured SnO2 thin films were prepared by ultrasonic spray pyrolysis technique. Aqueous solution (0.05M) of SnCl4·5H2O in double distilled water was chosen as the starting solution for the preparation of the films. The stock solution was delivered to nozzle with constant and uniform flow rate of 70 ml/h by Syringe pump SK5001. Sono-tek spray nozzle, driven by ultrasonic frequency of 120 k...

The net release of insulin, glucagon and somatostatin by the portal-drained viscera (PDV) and their net uptake by the liver in response to 3-d abomasal infusions of casein were measured in seven multicatheterized beef steers. The steers were fed 4.3 kg DM/d of a high-concentrate diet in 12 equal meals (13.1 Mcal ME/d and 95 g N/d). In two separate experiments, the abomasal infusion of 300 g cas...

Flexible displays fabricated using plastic substrates have a potential for being very thin, light weight, highly rugged with greatly minimized propensity for breakage, roll-to-roll manufacturing and lower cost. The emerging OLED display media offers the advantage of being a solid state and rugged structure for flexible displays in addition to the many potential advantages of an AM OLED over the...

1-Cycloalkyl-2-propene-1-ones were synthesized by electrophilic addition of cycloalkanecarboxylic acid chlorides and its mono- dichloride-substituted derivatives to ethylene in the presence an AlCl3 catalyst at a temperature –10 ÷ –150C dichloroethane medium. The resulting vinyl ketones converted chlorination CCl4 –50C corresponding 1-cycloalkyl-2,3-dichloro-1-propanones, which form 1-R´-3-cycl...
