The paper describes a two-drum root crop washer with chain gear, which was designed by the authors of this work and assembled for testing working in mini technological line processing. have calculated gear specifically design.
The ability of cells to invade basement membranes is critical to a number of important biological processes, such as cell metastasis, embryo implantation and early development, and inflammation. Several in vitro invasion assays have been developed so that the invasiveness of cells can be measured. These assays are also used to monitor the altered cell response to stimuli or inhibitors, such as ...
Design of a structurally defined helical assembly is described that involves recoding of the amino acid sequence of peptide GCN4-pAA. In solution and the crystalline state, GCN4-pAA adopts a 7-helix bundle structure that resembles a supramolecular lock washer. Structurally informed mutagenesis of the sequence of GCN4-pAA afforded peptide 7HSAP1, which undergoes self-association into a nanotube ...
