In North America, terrestrial records of biodiversity and climate change that span Marine Oxygen Isotope Stage (MIS) 5 are rare. Where found, they provide insight into how the coupling of the ocean-atmosphere system is manifested in biotic and environmental records and how the biosphere responds to climate change. In 2010-2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence that preserved evidence of past plant communities between similar to 140 and 55 lea, including all of MIS 5. At an elevation of 2705 m, the Ziegler Reservoir fossil site also contained thousands of well-preserved bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and bighorn sheep. In addition, the site contained more than 26,000 bones from at least 30 species of small animals including salamanders, otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds. The combination of macro- and micro-vertebrates, invertebrates, terrestrial and aquatic plant macrofossils, a detailed pollen record, and a robust, directly dated stratigraphic framework shows that high-elevation ecosystems in the Rocky Mountains of Colorado are climatically sensitive and varied dramatically throughout MIS 5

"Suite à plus de deux années de recherches, le projet de l’American Bar Association (ABA) concernant la juridiction du cyberespace, « Achieving Legal and Business Order in Cyberspace: A Report on Global Jurisdiction Issues Created by the Internet », a été publié dans l’édition du mois d’août 2000 de la revue juridique The Business Lawyer. Ce rapport poursuivait deux objectifs distincts : Tout d’abord, effectuer une analyse globale des complexités potentielles entourant les conflits juridictionnels découlant du commerce en ligne. Ensuite, élaborer une liste exhaustive des solutions pouvant être utilisées pour résoudre de tels conflits. Le présent article se veut un résumé concis et accessible des trois grandes sections du « Cyberspace Jurisdiction Report » : (1) les solutions proposées aux problèmes juridictionnels découlant des conflits résultant du commerce électronique ; (2) afin d’appuyer les solutions proposées : l’utilisation d’exemples d’occasions où la technologie a déjà, par le passé, causé la métamorphose de certains paradigmes juridictionnels; et (3) afin d’appuyer les solutions proposées : l’utilisation d’un contexte doctrinal."

The Lean Aircraft Initiative began in the summer of 1992 as a “quick look” into the feasibility of applying manufacturing principles that had been pioneered in the automobile industry, most notably the Toyota Production System, to the U.S. defense aircraft industry. Once it was established that “lean principles” (the term coined to describe the new paradigm in automobile manufacturing) were indeed applicable to aircraft manufacturing as well, the Initiative was broadened to include other segments of the defense aerospace industry. These consisted of electronics/avionics, engines, electro-mechanical systems, missiles, and space systems manufacturers. In early 1993, a formal framework was established in which 21 defense firms and the Air Force formed a consortium to support and participate in the Initiative at M.I.T.

Indehiscent fruits of six tree species, common in Matabeleland were examined in in vitro and in vivo trials. The results for two of them, Acacia nilotica and Dichrostachys cinerea are presented here. Acacia nilotica-contained more total phenolics than D. cinerea, but less nitrogen (N) and fibre (ADF and NDF). After 48 h incubation, in vitro OMD of both species was increased by PEG and NaOH or wood ash treatment, except when NaOH or wood ash were used in combination with PEG with D. cinerea fruits. DM intake, DMD were lowest and N-retention negative in goats fed A. nilotica as supplement. However when fed a supplement of D. cinerea, untreated or treated with PEG or NaOH, digestibility and N-retention were highest, and similar to a commercial goat meal, with the untreated fruit. In a trial in which milking does were supplemented with D. cinerea fruits, for 65 before and 65 days after kidding, kid birthweight and weaning weight were increased by supplementation. Deaths of twin-born kids were lowest in the supplemented but unmilked group. Supplementation with D. cinerea fruit resulted in improved goat performance. The only treatment applied of practical significance, wood ash, is currently being tested in an in vivo study. More research is required on detoxification of tannins, especially with A. nilotica.

Renewable energy such as biomass has given markets, including dairy farms, an effective approach to reducing the costs of sustaining a profitable business. Anaerobic digestion systems offer dairy farms a very effective way to reduce manure odor, comply with soil and water pollution regulations, manufacture compost for general market sales, produce irrigation capacity and generate on-site electricity as well as the ability to sell excess electricity back to the local utilities. This project defines anaerobic digestion technologies and practices, analyzes case studies and presents a step-by-step anaerobic digestion project startup checklist. The result is an anaerobic digestion project working guide that acts as a tool to aid dairy farmers in their own potential anaerobic digestion project.
