the effect of feeding silage of leaf and stem of banana tree with waste date palm on feed intake, microbial protein synthesis and blood parameters using four adult rams in a change- over design with four 21-days period were examined. eighty five kg leaf and stem of banana tree with 15 kg of waste date palm were mixed together and ensiled for 45 days. chemical composition and sensory evaluation ...

T paper presents a binary search heuristic algorithm for the rectangular strip-packing problem. The problem is to pack a number of rectangles into a sheet of given width and infinite height so as to minimize the required height. We first transform this optimization problem into a decision problem. A least-waste-first strategy and a minimal-inflexion-first strategy are proposed to solve the rela...
