Food Code 2013 (on CD-ROM) (powered by Flipviewer).

imagesThe Food Drug Administration (FDA) Food Code 2013 contains the latest FDA advice on preventing foodborne disease in food outlets including restaurants, grocery stores, and food vending operations. It consists of model requirements for safeguarding public health and ensuring that food offered to the consumer is safe, unadulterated, and honestly presented. The model is adopted by local, state, and federal governmental jurisdictions for administration by the various governmental units within each jurisdiction that have been delegated compliance responsibilities.

Launch and Assembly Reliability Analysis for Mars Human Space Exploration Missions

imagesCA18WE00NASA’s long-range goal is focused upon human exploration of Mars. Missions to Mars will require campaigns of multiple launches to assemble Mars Transfer Vehicles in Earth orbit. Launch campaigns are subject to delays, launch vehicles can fail to place their payloads into the required orbit, and spacecraft may fail during the assembly process or while loitering prior to the Trans-Mars Injection (TMI) burn. Additionally, missions to Mars have constrained departure windows lasting approximately sixty days that repeat approximately every two years. Ensuring high reliability of launching and assembling all required elements in time to support the TMI window will be a key enabler to mission success. This paper describes an integrated methodology for analyzing and improving the reliability of the launch and assembly campaign phase. A discrete event simulation involves several pertinent risk factors including, but not limited to: manufacturing completion; transportation; ground processing; launch countdown; ascent; rendezvous and docking, assembly, and orbital operations leading up to TMI. The model accommodates varying numbers of launches, including the potential for spare launches. Having a spare launch capability provides significant improvement to mission success. For more

Bureau of Mines Publications and Journal Articles 1910-1996

The United States Bureau of Mines of the Department of the Interior was established in 1910 by the Department of the Interior and abolished on March 30, 1996.

NTIS maintains the entire collection of the Bureau’s publications, some 5,000 documents. This page lists the printed indexes that are available to locate these publications as well as providing a search box to locate publications in the NTIS collection.

The Bureau was established to conduct inquiries and scientific and technological investigations on mining and the preparation, treatment, and use of mineral substances; to promote health and safety in the mineral industries; to conserve material resources; to promote economic development; to increase efficiency in the mining, metallurgical, quarrying, and other mineral industries; and to inquire into the economic conditions affecting those industries.  To conduct your search of our

Culn(Ga)Se2 (CIGS) Nanowire Solar Cells

Developing CIGS solar cells calls for the understanding of materials and processing in order to translate the record small efficiency to module and the strategy to produce thin cells for materials and processing saving. This project has exploited nanostructuring of CIG solar cells, including nanowires and nanotextured substrates. We showed that nanowires function as well-defined CIGS-CdS p-n junction for understanding the chemical fluctuation, defect formation interface and grain boundary behaviors and the effect of ion diffusion, which are important but complicated issues for solar cell fabrication. We have also demonstrated effective nanoscale photon management on nanotextured substrate to provide opportunity for thin CIGS solar cells. We also developed the scalable methods for producing such nanotextured substrates. The research output in this project helps advancing the CIGS solar cells and broadly other solar cell technologies in cost reduction per unit power.  Product No. DE20131072974  For availability

Improved Structure and Fabrication of Large, High-Power KHPS Rotors, Final Scientific/Technical Report

The research, development, deployment and demonstration (RDD&D) conducted under this US Department of Energy (DOE) Advanced Water Power Program (AWPP) project has significantly contributed to advancing the design and construction of stronger, larger, and higher-capacity composite turbine blades for use in the nascent Marine and Hydrokinetic (MHK) renewable energy industry. MHK turbines convert energy from water current resources, including tidal and river flows, into electricity. Specifically, Verdant Power, Inc, working in partnership with the National Renewable Energy Laboratory (NREL), Sandia National Laboratories (SNL), and the University of Minnesota (UMN) St. Anthony Falls Laboratory (SAFL), among other partners, used evolving Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) models and techniques to improve the structure and fabrication of large, high-power composite Kinetic Hydropower System (KHPS) rotor blades. The execution of the project was organized by a series of ten tasks with the objectives to: design; analyze; develop for manufacture and fabricate; and thoroughly test, in the lab and at full scale in the water, the improved KHPS rotor blade.  Pub No. DE20131084212

Developing a High Throughput Protocol for using Soil Molecular Biology as Trace Evidence. Final Technical Report

Soil has a long and successful history as trace evidence. Originally, the use of soil as trace evidence was accomplished via light microscopy. But the value of soil as trace evidence has expanded significantly with the development of new techniques. Most recently these include using the biochemical molecules from soil microbial communities to make a fingerprint of the specific soil. The current research examines the changes to the microbial community profile that take place during storage of a soil sample. The purpose of this research was to determine the optimal conditions for storing soil when using biochemical molecules as trace evidence. The examination of the soil microbial biochemical molecules was divided into two sections: DNA profiles and fatty acid profiles.  Publication Number:  PB2013106266/www.ntis.govbiochem[1]

Integration Costs: Are They Unique to Wind and Solar Energy

In the past several years there has been considerable interest and effort in assessing wind integration costs (solar integration costs have not been as rigorously pursued but this is expected to change with increasing solar energy penetration). This interest is understandable, because wind energy does increase the variability and uncertainty that must be managed on the power system. Measuring this integration cost can be challenging. In addition to wind and solar energy (and load), there are other sources of variability and uncertainty that must be managed in the power system. In this paper we describe some of these sources, which can include the performance of thermal plants. We also show that even the introduction of baseload generation can cause additional ramping and cycling, along with lower capacity factor, of at least some thermal units. The paper concludes by demonstrating that integration costs are not unique to wind and solar, and should perhaps instead be assessed by power plant and load performance instead of technology type.

United States Conference of Mayors. Clean Energy Solutions for America’s Cities.

The report, from the National League of Cities US Conference of Mayors reports that most mayors expect their cities deployments of new energy technologies to increase over the next five years, despite today’s economic climate. Three in four cities (75%) say their use of new energy technologies is likely to grow, with more than one-quarter (27%) of the 396 cities in this survey expecting the increase to be significant. Cities in the Northeast and South anticipate faster growth, but there is little difference across cities small and large cities alike expect to be deploying more clean technology in five years than they do currently. Only three percent of cities expect their use of new energy technologies to decrease during this period.
