Uranium Mining in Namibia: The Mystery Behind 'Low Level Radiation'

This report is the result of a project on uranium mining in Namibia commissioned by the Centre for Research on Multi-national Corporations (SOMO). The findings are based on secondary literature drawn mainly from the writings of Earthlife Namibia and empirical data collected by LaRRI during July and August 2007

Explosive Welding of Aluminum, Titanium and Zirconium to Copper Sheet Metal

The main material properties affecting the explosive weldability of a certain metal combination are the yield strength, the ductility, the density and the sonic velocity of the two metals. Successful welding of the metal combination depends mainly on the correct choice of the explosive welding parameters; i.e., the stand off distance, the weight of the explosive charge relative to the weight of the flyer plate and the detonation velocity of the explosive. Based on the measured and the handbook values of the properties of interest, the explosive welding parameters were calculated and the arrangements for the explosive welding of the Al alloy 6061-T6, titanium and zirconium to OFHC copper were determined. The relatively small sheet metal thickness (1/8") and the fact that the thickness of the explosive layer must exceed a certain minimum value were considered during the determination of the explosive welding conditions. The results of the metallographic investigations and the measurements of the shear strength at the interface demonstrate the usefulness of these calculations to minimize the number of experimental trials

Examining Phenotypic Structural Traits as Indicators for Reproductive Longevity Success in Sows

The objective of this study was to examine structure and body conformation traits of 494 gilts/sows as a prediction of reproductive longevity in sows. This study focused on specific traits including body length, body depth, front and rear pastern angles, knee angle, and hock angle. The primary method of data collection was based on videos. Still images were pulled from the videos when the sow was standing in a natural stance. The images were analyzed and interpreted objectively with Image J which gives the availability to measure distance and angles given known references in the images. The structural data was analyzed for association with reproductive efficiency including feed intake, wean to estrus interval, weight loss, number born alive, and number of parities achieved. The angle measurements on young sows are not as consistent as older, calmer sows. Front pastern angle was significantly associated with P1 Success at 112 days of age. This trait is critical to early survival before any animals are culled. Angles showed significance or trended toward significance predominately at the early first gestation timepoint. Height at flank at all timepoints is significantly associated with LTNP. Smaller animals have a greater success reaching parity 4 and significant advantages in lifetime reproduction traits compared to the larger animals. As producers are making selections on their replacement gilts, they should avoid selecting the largest females
