Two Wheels Through Terror: Diary of a South American Motorcycle Odyssey
Glen Heggstad is an adventure motorcyclist who seeks out and rides the most rugged places on the planet. He has been a Hell's Angel and a martial arts competitor, but no amount of training or experience was able to prepare him for what he became while riding to the southern tip of South America: a prisoner. This book is the shocking travelogue of Heggstad's journey through Central and South America, including his capture by Colombia's rebel ELN army, and the eventual realization of a dream. Follow along on his exciting, round-trip to the tip of the world, made all the more amazing by its intermission at the hands of terrorists. Heggstad was ripped from his motorcycle, robbed of everything, and forced to march through strange jungles with assault rifles in his back. He was fed only small amounts of rice and water and forced to carry heavy equipment, heavy packs, and heavy doubts about his future. Even with all the hand-to-hand and sophisticated combat training Heggstad possessed, it was his shrewd thinking, precise planning, and a "do-or-die" last act of desperation that eventually secured his freedom. .

An automated extraction approach for isolation of 24 polyaromatic [An article from: Analytica Chimica Acta]
This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: An efficient and selective analytical method for determination and quantification of 24 various polyaromatic hydrocarbons (PAHs) in blue mussel (Mytilus edulis), salmon fillet (Salmo salar), fish oil and fish feed has been developed. The samples were extracted by means of accelerated solvent extraction (ASE) technique followed by a purification step with gel permeation chromatography (GPC). Identification and quantification were performed by using GC/MS. The novel combination of silica and alumina in the extraction step furnishes highly purified analytes for the most of the 24 PAHs investigated, and thus a fast and selective analytical method is developed. A small limitation with the method concerns the quantification of acenaphthene (Ace), fluorene (Fl), pyrene (Py) and benzo[a]anthracene (BaA), as the found values for these compounds do not match the certified values (SRM 2977, mussel tissue). Chrysene (Chr) and triphenylene (Tph) give unresolved peaks. The limits of detection (LOD) and limits of quantification (LOQ) found for benzo[a]pyrene (BaP) were 1.7 and 0.44pg/g (LOD), and 5.8 and 1.5pg/g (LOQ) for salmon fillet and blue mussel, respectively. This is in a very good accordance with respect to the European Community legislation for official control of BaP levels in foodstuff. The method may be used for qualitative identification of petroleum compounds in marine matrixes. .
