Abstract: In the improved method of shaping a semisolid metal, liquid alloy having crystal nuclei and at a temperature not lower than the liquidus temperature or a partially solid, partially liquid alloy having crystal nuclei and at a temperature less than the liquidus temperature but not lower than the molding temperature is poured into a holding vessel having a thermal conductivity of at least 1 kcal/mh°C, cooled at an average cooling rate of 0.01 °C/s - 3.0 °C/s and held as such until just prior to the start of shaping under pressure, whereby fine primary crystals are generated in said alloy solution and the alloy within said holding vessel is temperature adjusted by induction heating such that the temperatures of various parts of the alloy fall within the desired molding temperature range for the establishment of a specified fraction liquid not later than the start of shaping and the alloy is recovered from said holding vessel, supplied into a forming mold and shaped under pressure. Shaped parts having fine and spherical microstructures can be produced in a convenient, easy and inexpensive manner without relying upon agitation by the conventional mechanical and electromagnetic methods.

Title: Method for genetic engineering of disease resistance using the dr206 class of proteins
Inventor: WANG YAPING
IPC: C12N15/82
Filed: 1998-07-03
Abstract: To identify genes effective against the blackleg fungus Leptosphaeria maculans, we have transformed canola (brassica napus) with four pea (Pisum sativum) genes under constitutive control by the CaMV 35S promoter: PR10.1, chitinase, Drr206 and defensin. Transgenic lines containing single copy T-DNA insertions for each gene were screened for both seedling (cotyledonary) and adult plant resistance. Lines for which pea Drr206 or defensin mRNA was expressed also showed decreased disease scores when inoculated with L. maculans or Sclerotinia sclerotiorum, compared to non-expressing transgenic lines. For PR10 and chitinase transgenics, there was little or no enhancement of resistance. Furthermore, resistance to L. maculans co-segregated with Drr206 and defensin transgenes. Extracts from Drr206 and defensin transgenic plants inhibited fungal growth in-vitro. Drr206 transgenic plants also demonstrated decreased hyphal growth at inoculation sites, and evidence of a hypersensitive response.

Title: Method and apparatus for enhanced partial packet discard
Inventor: KING GREGORY LLOYD
IPC: H04L12/56
Filed: 1998-07-09
Abstract: In an enhanced partial packet discard (PPD) methodology, if an end-of packet cell is discarded for non-PPD reasons, all non-end-of packet cells of the immediately following packet are discarded. When an end-of-packet cell may validly be discarded, a switch faced with an end-of-packet cell may discard that cell if the last cell admitted to the buffer was an end-of-packet cell. To reduce the likelihood of having to drop end-of-packet cells, a buffer is configured to include a partial packet discard threshold such that the buffer space between that threshold and the end of the buffer is reserved for use by end-of-packet cells.
Patent CA-2243118-A1 (CA)
Inventor: WELLS GEORGE A
IPC: A61K47/48
Filed: 1997-06-20
Abstract: This invention is directed to the surprising and unexpected discovery that the clinical incidence of HUS arising from enterohemorrhagic E. coli infection is significantly reduced by the time critical administration of a pharmaceutical composition comprising a pharmaceutically inert affinity support comprising an .alpha.Gal(14).beta.Gal subunit which subunit binds the SLT. Specifically, it has been found that the clinical incidence of HUS arising from enterohemorrhagic E. coli infection is reduced when this pharmaceutical composition is administered within 3 days of presentation of the infection.  Contrarily, administration of this pharmaceutical composition after this time frame or when organs other than the intestine are involved in the infection, substantially reduces the ability of this composition to reduce the incidence of HUS.
