I. Food intake and rates of protein, lipid and energy deposition during growth were measured for lean and congenitally obese (fatty) Zucker rats offered from 34 d of age to slaughter at 66 d of age, one of six semi-synthetic diets containing casein (C) in the following amounts (g Clkg): 40C, moC, 150C, 3wC, 500C and 700C. 2. In Expt I, groups of four male rats were offered each diet to appetite...

Introduction The integration of fuel processors, the catalytic units that can convert fossil fuels to hydrogen-rich streams, with hydrogen fuel cells is considered as a promising solution to the problems related to the availability, distribution and storage of hydrogen. Recent computer-based studies have demonstrated the possibility of efficient hydrogen production on-board the vehicles through...

The aromatic rings of polystyrene (PS) were hydrogenated in decahydronaphthalene (DHN) expanded with supercritical carbon dioxide (scCO2). Conducting the hydrogenation in scCO2-DHN offers the benefits of improved transport properties, specifically lower solution viscosity and a higher PS diffusion coefficient. Various Pd catalysts are effective for hydrogenating the aromatic rings of PS at temp...

The SNC (Shergotty-Nakhla-Chassigny) meteorites have recorded interactions between martian crustal fluids and the parent igneous rocks. The resultant secondary minerals which comprise up to ~ 1 vol.% of the meteorites – provide information about the timing and nature of hydrous activity and atmospheric processes on Mars. We suggest that the most plausible models for secondary mineral formation ...

Title of Dissertation: INFLUENCE OF CRYOGENIC TEMPERATURE AND MICROSTRUCTURE ON FATIGUE FAILURE OF INDIUM SOLDER JOINT Rui Wu Chang, Doctor of Philosophy, 2008 Dissertation directed by: Associate Professor F. Patrick McCluskey Department of Mechanical Engineering This thesis aims to develop a fundamental understanding of the underlying mechanisms that govern indium attach degradation in applica...

The thermal stability of silicone polymers, fluids and resins has been well documented and studied extensively. The high temperature performance of silicone adhesives and sealants used for electronics applications has only moderately been investigated. This report documents the effects of very high temperature exposures to electronics-grade silicone adhesives and sealants for such properties as...

Introduction: Mars atmospheric pCO2 levels between 4.5-3.8 Ga have commonly been estimated at 13 bar [1,2] based on the existence of fluvial features or sedimentary rocks on the surface of Mars. Most of the original atmospheric CO2 (90-95%) has been lost through impact erosion, sputtering processes associated with the solar wind and sequestration within the crust [3]. This has been correlated w...

A novel fully-logic compatible Lateral CBRAM has been demonstrated by a sidewall Ti-atomic switch between poly-Si and a CMOS logic regular contact plug, the lateral Ti-based sandwich CBRAM structure can be well turned on or off at 1mA/1.5V by bipolar switching operations. More than 5X On/Off resistance ratio is successfully achieved after more than 1,000 pulse cycles, and it also has very stabl...

Understanding the correlation between film structure and its ferromagnetic properties is very important for applications. Despite significant lattice mismatch epitaxial (001) fcc Ni films can be grown on MgO substrates using sputtering or molecular beam epitaxy (MBE). For both types of films it is observed that the average magnetization switching field is very similar but its azimuthal dependen...

The influence of maleation on thermal and dynamic-mechanical properties of wood-PVC composites was investigated in this study. Experimental results indicated that maleation had a significant influence on most of the properties for wood-PVC composites. Storage modulus (E’), loss modulus (E”), and complex modulus (E*) of resultant wood-PVC composites were related to the retention levels and graft...
