Abstract: A system and method for growing and maintaining biological material including producing a protein associated with the tissue, selecting cells associated with the tissue, expanding the cells, creating at least one tissue bio-ink including the expanded cells, printing the at least one tissue bio-ink in at least one tissue growth medium mixture, growing the tissue from the printed at least one tissue bio-ink, and maintaining viability of the tissue.

Abstract: In accordance with one aspect of the invention, an automation control device, such as a host or hub, is provided with functionality so that it becomes a multi-role automation control device. One such multi-role automation control device produces an on screen display which enables a user to select predetermined lighting scenes or television channels, and to control other devices.

Abstract: The present disclosure provides methods of producing plants with preferred levels of cell wall biosynthesis; and uses of such plants. The inventors have identified that the GFR9, CCoAOMT and MYB41 genes are major regulators of the cell wall biosynthesis pathway. Plants with modulated cell wall biosynthesis, based on modulation of the expression or activity of the GFR9, CCoAOMT and MYB41 genes, have divergent uses including pulp and paper production, and bioproduct production.

Abstract: In a method for operating a urea dosing system in an exhaust aftertreatment system (EATS) of an engine, an ambient temperature is measured in an environment in which the EATS is disposed, one or more temperatures associated with the EATS to which there is a relationship to a temperature of area in the urea dosing system are monitored. After turning off the engine, whether urea in the urea dosing system is subject to freezing is determined based on the measured ambient temperature and the one or more monitored temperatures. A reversion operation is performed after turning off the engine with a delay until one or more events occur, the one or more events including determining that urea in the urea dosing system is subject to freezing. An engine system is also provided.
