This FEMP Technical Assistance Case Study describes the use of solar water heating at the Chickasaw National Recreation Area in Oklahoma. The solar systems are an environmentally sound and cost-effective way to heat water. By using renewable energy technologies to satisfy its mandate to provide services for visitors and protect the park system's natural resources, the National Park Service sets a good example for other Federal agencies and the general public.

The long-term well-being of the nation and maintenance of a sustainable leadership position in agriculture, forestry, and manufacturing, clearly depend on current and near-term support of multidisciplinary research for the development of a reliable renewable resource base. This document sets a roadmap and priorities for that research. America needs leadership that will continue to recognize, support, and move rapidly to meet the need to expand the use of sustainable renewable resources. This roadmap has highlighted potential ways for progress and has identified goals in specific components of the system. Achieving success with these goals will provide the opportunity to hit the vision target of a fivefold increase in renewable resource use by 2020.

With its extensive requirements for environmental systems, flexibility, and growth, energy-efficient laboratory design is a challenge. Unlike other building types, a laboratory has HVAC and energy considerations that cannot be deferred; they must play a key, formative role if the building is to succeed. This publication should help to sensitize building professionals and their clients to the complex array of issues associated with efficient laboratory design and performance. This is only an introduction and you will need to consult other resources for in-depth information about energy-efficient laboratory design.

This is a bimonthly newsletter from DOE's Office of Industrial Technologies to promote the use of energy-efficient industrial systems.

Polyethylene microencapsulation physically homogenizes and incorporates mixed waste particles within a molten polymer matrix, forming a solidified final waste form upon cooling. Each individual particle of waste is embedded within the polymer block and is surrounded by a durable, leach-resistant coating. The process has been successfully applied for the treatment of a broad range of mixed wastes, including evaporator concentrate salts, soil, sludges, incinerator ash, off-gas blowdown solutions, decontamination solutions, molten salt oxidation process residuals, ion exchange resins, granular activated carbon, shredded dry active waste, spill clean-up residuals, depleted uranium powders, and failed grout waste forms. For waste streams containing high concentrations of soluble toxic metal contaminants, additives can be used to further reduce leachability, thus improving waste loadings while meeting or exceeding regulatory disposal criteria. In this configuration, contaminants are both chemically stabilized and physically solidified, making the process a true stabilization/solidification (S/S) technology. Unlike conventional hydraulic cement grouts or thermosetting polymers, thermoplastic polymers such as polyethylene require no chemical. reaction for solidification. Thus, a stable, solid, final waste form product is assured on cooling. Variations in waste chemistry over time do not affect processing parameters and do not require reformulation of the recipe. Incorporation of waste particles within …

Sulfur polymer cement (SPC) is a thermoplastic polymer consisting of 95 wt% elemental sulfur and 5 wt% organic modifiers to enhance long-term durability. SPC was originally developed by the U.S. Bureau of Mines as an alternative to hydraulic cement for construction applications. Previous attempts to use elemental sulfur as a construction material in the chemical industry failed due to premature degradation. These failures were caused by the internal stresses that result from changes in crystalline structure upon cooling of the material. By reacting elemental sulfur with organic polymers, the Bureau of Mines developed a product that successfully suppresses the solid phase transition and significantly improves the stability of the product. SPC, originally named modified sulfur cement, is produced from readily available, inexpensive waste sulfur derived from desulfurization of both flue gases and petroleum. The commercial production of SPC is licensed in the United States by Martin Resources (Odessa, Texas) and is marketed under the trade name Chement 2000. It is sold in granular form and is relatively inexpensive ({approx}$0.10 to 0.12/lb). Application of SPC for the treatment of radioactive, hazardous, and mixed wastes was initially developed and patented by Brookhaven National Laboratory (BNL) in the mid-1980s (Kalb and Colombo, 1985; …

General use fact sheet about geothermal energy in Nevada. Nevada holds the largest amount of untapped geothermal resources in the U.S., with a potential of 2,500 to 3,700 megawatts of electricity (Mwe).

Excess electrons can be introduced into liquids by absorption of high energy radiation, by photoionization, or by photoinjection from metal surfaces. The electron's chemical and physical properties can then be measured, but this requires that the electrons remain free. That is, the liquid must be sufficiently free of electron attaching impurities for these studies. The drift mobility as well as other transport properties of the electron are discussed here as well as electron reactions, free-ion yields and energy levels, Ionization processes typically produce electrons with excess kinetic energy. In liquids during thermalization, where this excess energy is lost to bath molecules, the electrons travel some distance from their geminate positive ions. In general the electrons at this point are still within the coulombic field of their geminate ions and a large fraction of the electrons recombine. However, some electrons escape recombination and the yield that escapes to become free electrons and ions is termed G{sub fi}. Reported values of G{sub fi} for molecular liquids range from 0.05 to 1.1 per 100 eV of energy absorbed. The reasons for this 20-fold range of yields are discussed here.

The official Government edition of the Final Report of the National Commission on Terrorist Attacks Upon the United States (also known as the 9-11 Commission, an independent, bipartisan commission created by congressional legislation and the signature of President George W. Bush in late 2002), provides a full and complete account of the circumstances surrounding the September 11, 2001 terrorist attacks, including preparedness for and the immediate response to the attacks. Provides recommendations designed to guard against future attacks.

Comparing complete animal mitochondrial genome sequences is becoming increasingly common for phylogenetic reconstruction and as a model for genome evolution. Not only are they much more informative than shorter sequences of individual genes for inferring evolutionary relatedness, but these data also provide sets of genome-level characters, such as the relative arrangements of genes, that can be especially powerful. We describe here the protocols commonly used for physically isolating mtDNA, for amplifying these by PCR or RCA, for cloning,sequencing, assembly, validation, and gene annotation, and for comparing both sequences and gene arrangements. On several topics, we offer general observations based on our experiences to date with determining and comparing complete mtDNA sequences.
