This book was released on 2018-07-08 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this project was to determine assimilation of CO2 and efficiency of water use in wheat grown to maturity in a low pressure total gas pressure environment. A functional test of the low pressure plant growth chamber system was accomplished in February and March of 1993 wherein this objective was partially achieved. Plants were grown to maturity in the chambers. Data were actively collected during the first 29 days. The plants were allowed to maintain themselves at the CO2 compensation point until day 45 of the study at which point active atmospheric regulation was resumed. This provided data at the vegetative and reproductive stages of the life cycle of the plants. However, this information may not be representative of the performance of the plants due to the loss of low pressure on a number of days during the study, which affected the plants by changing the pressure potential of the tissues. The performance of the system will be discussed on a component by component basis. The maintenance of the plants at the CO2 compensation point was driven by the failure of the computer program operating the system. The software problems that arose during the functional test have since been corrected. Results from the functional test also indicated that the plants were not receiving adequate light and nutrients. The growth chambers have been relocated and the growth room modified to compensate for these deficiencies. Rykiel, Edward J., Jr. and Drew, Malcolm C. and Etter, Brad D. Unspecified Center...

Book excerpt: Depleting fossil fuel reserves and adverse effects of fluctuating oil prices have renewed interest in alternative and sustainable sources of energy. Bioenergy: Biomass to Biofuels takes on this topic and examines current and emerging feedstocks and advanced processes and technologies enabling the development of all possible alternative energy sources: solid (wood energy, grass energy, and other biomass), liquid (biodiesel, algae biofuel, ethanol), and gaseous/electric (biogas, syngas, bioelectricity). Divided into seven parts, Bioenergy gives thorough consideration to topics such as feedstocks, biomass production and utilization, life cycle analysis, Energy Return on Invested (EROI), integrated sustainability assessments, conversions technologies, biofuels economics and policy. In addition, contributions from leading industry professionals and academics, augmented by related service-learning case studies and quizzes, provide readers with a comprehensive resource that connect theory to real-world implementation. - Provides a comprehensive overview and in-depth technical information of all possible bioenergy resources (solid, liquid, and gaseous), including cutting-edge topics such as advanced fuels and biogas - Integrates current state of art coverage from feedstocks to cost-effective conversion processes to biofuels economic analysis and environmental policy - Features case studies and quizzes for each section derived from the implementation of actual hands-on biofuel projects as part of service learning
