Genetic Engineering (3500 words)
Definition: Genetic engineering, recombinant DNA technology and biotechnology – the buzz words you may have heard often on radio or TV, or read about in featured articles in newspapers or popular magazines. It is a set of techniques that are used to achieve one or more of three goals: to reveal the complex processes of how genes are inherited and expressed, to provide better understanding and e...
متن کاملDev122564 3500..3511
Although tissue regeneration has been studied in a variety of organisms, from Hydra to humans, many of the genes that regulate the ability of each animal to regenerate remain unknown. The larval imaginal discs of the genetically tractable model organism Drosophila melanogaster have complex patterning, wellcharacterized development and a high regenerative capacity, and are thus an excellent mode...
متن کاملDevelopment of a 3500-Tonne Field Robot
The mining industry is highly suitable for the application of robotics and automation technology, since the work is arduous, dangerous, and often repetitive. This paper presents a broad overview of the issues involved in the development of a physically large and complex field robotic system—a 3500-tonne mining machine (dragline). Draglines are “walking cranes” used in open-pit coal mining to re...
متن کاملOn BC-trees and BC-subtrees
A BC-tree (block-cutpoint-tree) is a tree (with at least two vertices) where the distance between any two leaves is even. Motivated from the study of the “core” of a graph, BC-trees provide an interesting class of trees. We consider questions related to BC-trees as an effort to make modest progress towards the understanding of this concept. Constructive algorithms are provided for BC-trees with...
متن کاملCoronium 3500: A Solarsonic Installation for Caramoor
This paper describes the development, creation, and deployment of a sound installation entitled Coronium 3500 (Lucie’s Halo), commissioned by the Caramoor Center for Music and the Arts. The piece, a 12-channel immersive sound installation driven by solar power, was exhibited as part of the exhibition In the Garden of Sonic Delights from June 7 to November 4, 2014, and again for similar duration...
