An ink-jet recording sheet comprising a paper support coated with a polyolefin resin on both sides of the paper support, the polyolefin resin-coated paper support having thereon a porous ink receptive layer containing a hydrophilic polymer, wherein the paper support has a ratio of a Cobb value to a basis weight of not more than 0. In particular, novel engineered hybrid insecticidal proteins having toxicity to at least corn rootworm are provided. After the control chip receives the training sequence, the control chip will produce the training data to compare with the predefined pattern inside it and adjust the control delay time. Some of the ribs are internally reinforced by a structure comprising two spaced apart layers of orthogonal intersecting spaced apart wires, running parallel to the length and breadth of the rectilinear shape of the frame within the ribs to increase their rigidity.
