Patent number: 11105565Abstract: A heat exchanger assembly has a frame including: a plurality of legs; first and second lower transversal members extending perpendicular to and interconnecting the legs; a plurality of upstanding members extending upwardly from respective ones of the legs, a lower end of each upstanding member being connected to a corresponding leg at a junction therebetween; an upper transversal member interconnecting upper ends of the upstanding members; and an upper frame assembly. The frame components are weldlessly connected to one another. First and second heat exchanger panels exchange heat with air pulled into the heat exchanger assembly and are disposed in a V-configuration. An upper end of each heat exchanger panel is connected to upper retaining members of the upper frame assembly.

Publication number: 20160340683Abstract: The present invention provides a novel method for the transduction and/or transfection of plant cells. Cell-penetrating peptides (CPPs) have been successfully employed as nanocarriers to deliver proteins and oligonucleotides to single plant cell microspores as well as multi-cellular zygotic embryos. The efficiency of CPP internalization and further delivery of a macromolecular cargo comprising a protein and/or an oligonucleotide can be enhanced by permeabilization of the zygotic embryos.Type: ApplicationFiled: June 2, 2016Publication date: November 24, 2016Inventors: Francois EUDES, Archana CHUGH, Priti MAHESHWARI

Publication number: 20080134360Abstract: The growing controversy over GM/novel-trait crops and food products that possess novel industrial or nutritional traits, has resulted in an increased need for technologies that allow the rapid and reliable identification of GM/novel-trait crops so that they can be identified, and segregated if necessary, at the various stages of production and processing. A visual seed identity system is described that permits the identification and tracing of each individual seed through the upstream value chain, from field increase to the processing plant. These traits are genetically controlled, transmitted to progeny by either pollen or ovule and expressed in developing seed, showing a xenia effect. That novelty of this proposed IP system will facilitate early mitigation measures if out-crossing or admixtures occur and exceed a threshold limit set by regulatory agencies.Type: ApplicationFiled: June 14, 2006Publication date: June 5, 2008Applicant: Her Majesty the Queen in Right of Canada, as Rep. by the Minister of Agriculture and Agri-FoodInventors: Robert J.
