Ni/SiO2-ZrO2 catalysts with Ni loadings of 1 to 13 wt-% were prepared, characterized by elemental analysis, X-ray diffraction, N2 sorption, temperature programmed oxidation, temperature programmed reduc- tion, and tested for their activity and stability in the dry reforming of methane with carbon dioxide at 850 ℃, gas hourly space velocity of 6000 and 1800 h^-1 and atmo- spheric pressure. The SiO2-ZrO2 support as obtained through a simple and efficient sol-gel synthesis is highly porous （ABET = 90 m^·g^-1, dp= 4.4 nm） with a homogeneously distributed Si-content of 3 wt-%. No loss of Si or formation ofmonoclinic ZrO2, even after steaming at 850 ℃ for 160 h, was detectable. The catalyst with 5 wt-% Ni loading in its fully reduced state is stable over 15 h on-stream in the dry reforming reaction. If the catalyst was not fully reduced, a reduction during the early stages of dry reforming is accompanied by the deposition of up to 44 mg· g^-1 carbon as shown by experiments in a magnetic suspension balance. Rapid coking occurs for increased residence times and times-on-stream starting at 50 h. The Ni loading of 5 wt-% on SiO2-ZrO2 was shown to provide an optimal balance between activity and coking tendency.

A three-stage molding process involving microcellular injection molding with core retraction and an ＂out-of-mold＂ expansion was developed to manufacture thermoplastic polyurethane into lightweight foams of varying local densities, microstructures, and mechanical properties in the same microcellular injection molded part. Two stages of cavity expansion through sequential core retractions and a third expansion in a separate mold at an elevated temperature were carried out. The densities varied from 0.25 to 0.42 g/cm3 （77% to 62% weight reduction）. The mechanical properties varied as well Cyclic com- pressive strengths and hysteresis loss ratios, together with the microstructures, were characterized and reported.

RF3 Brassica napus L. (InVigorTM Canola) has been in commercial cultivation since 1997. RF3 B. napus was produced by Agrobacterium-mediated transformation to provide glufosniate ammonium herbicide tolerance to the crop. Canola quality (CQ) varieties of Brassica juncea L. (Czern & Coss), a close relative of B. napus, have been available in Canada for more than 20 years. Currently, basf Agricultural Solutions is developing CQ RF3 B. juncea via conventional breeding with RF3 B. napus to provide similar herbicide tolerance in the B. juncea species. The insertion event RF3 contains the bar gene (origin Streptomyces hygroscopicus) coding for phosphinothricin acetyl transferase (PAT/bar) protein which confers tolerance to glufosinate-ammonium herbicides. RF3 also contains the barstar gene (origin Bacillus amyloliquefaciens), coding for the Barstar protein, which is an inhibitor of the Barnase protein. In the absence of Barnase, there is no impact of Barstar. Many safety studies have been conducted during the development of the canola quality lines of RF3 B. napus and RF3 B. juncea. This report seeks to compare the two species based on the scientific data generated during the safety assessments of RF3 B. napus and RF3 B. juncea and discusses the utility of using studies with one species to support the safety of the other species both containing the same insertion event.
