At each of three locations, 400 steers and an equal number of heifers were randomized to 10 treatment groups. The purpose of the studies was to evaluate the response of feedlot steers and heifers to single implants containing a combination of estradiol benzoate (EB) and trenbolone acetate (TBA) at two different ratios each at three doses. The selected ratios corresponded to 1E2(estradiol-17 bet...

Thermal lattice expansion in epitaxial SrTiO3(100) grown on Si(100) by molecular beam epitaxy was examined by in situ X-ray diffraction (XRD) at temperatures ranging from 25 °C to 1000 °C. The SrTiO3 layer thickness (~400 Å) was determined a priori by ex situ X-ray reflectivity (XRR). In addition, the SrTiO3(100) film was further characterized before and after thermal treatment by Rutherford ba...

Pulsed laser deposition (PLD) has been used to grow epitaxially oriented thin films of Cu and Pt on (100)-oriented substrates of both SrTiO3 and LaAlO3. The resulting films have been characterized for their crystalline orientations using x-ray diffraction (XRD) and for their surface morphologies using atomic force microscopy (AFM). The diffraction results illustrated that purely epitaxial Cu(10...

All homeworks should be submitted in a directory named hw 3 using svn or turnin as before. In case of problems, you should email a zip file containing the directory to [email protected] before the deadline. See course wiki for slip day policy and late submission penalties. IMPORTANT: The programming assignment in this homework is more challenging than in past homeworks. It is critical that...

Millimeter-wave and far-infrared frequencies (f > 100 GHz) remain one of the most underdeveloped frequency ranges, even though there are great numbers of potential applications in remote sensing, spectroscopy, plasma diagnostics, and communications. This is because the millimeter wave and far-infrared frequency range falls between two other frequency ranges in which conventional semiconductor d...
