A communication system must have adequate electrical protection in order to meet the reliability standards for commercially acceptable service and to keep down maintenance expenses. This report characterizes, from the viewpoint of electrical protection and coordination, the conditions of the electrical environment to which communication facilities are exposed. It gives consideration to both present and anticipated future conditions, and covers such topics as the effects of lightning, interference from power networks, electric shock, earth potential gradients, corrosion, over-voltage in AC power utilization circuits,her and electromagnetic pulses. Characterization of the Electrical Environment is a current reference on the design factors required to ensure reliable performance of communication facilities under field operating conditions. It will be useful as a manual for practicing engineers in telecommunications, and as a tutorial textbook in engineering schools in North America, Europe, and elsewhere.

Just below our feet is an environment that supports our infrastructure, yields water, provides for agriculture, and receives our waste. Our capacity to describe, or characterize, this environment is crucial to the solution of many resource, environmental, and engineering problems. And just as medical imaging technologies have reduced the need for exploratory surgeries, a variety of technologies hold the promise for rapid, relatively inexpensive noninvasive characterization of the Earth's subsurface. Seeing into the Earth examines why noninvasive characterization is important and how improved methods can be developed and disseminated. Looking at the issues from both the commercial and public perspectives, the volume makes recommendations for linking characterization and cost savings, closing the gap between the state of science and the state of the practice, and helping practitioners make the best use of the best methods. The book provides background on: The role of noninvasive subsurface characterization in contaminant cleanup, resource management, civil engineering, and other areas. The physical, chemical, biological, and geological properties that are characterized. Methods of characterization and prospects for technological improvement. Certain to be important for earth scientists and engineers alike, this book is also accessible to interested lay readers.

In earlier research in our lab, the manipulation of microtubules on gold patterned silicon wafers was achieved by E-beam lithography, Poly (ethylene glycol) self assembled monolayers (PEG-SAMs) and electrophoresis. To develop a technique for delicate single microtubule manipulation, further studies need to be done on PEG-SAMs and electrophoresis. As a foundation of this goal, we examined the electric field in an aqueous solution between two planar electrodes and the compatibility of the antifouling property of PEG-SAMs with the electric field. For this purpose, the distribution of microbeads was analyzed using a Boltzmann distribution. The amount of adsorbed microtubules on a PEG-SAM was examined to test the compatibility of the antifouling property of a PEG-SAM with concomitant exposure to electric field. It is shown that the product of the electric field and the effective charge of the microbead does not have a linear relation with the applied electric potential but an exponentially increasing function with respect to the potential. The antifouling property of the PEG-SAM was not retained after an exposure to the electric field.

Buildings account for 40% of primary energy consumption in the United States (residential 22%; commercial 18%). Most (70% residential and 79% commercial) is used as electricity. Thus, almost 30% of U.S. primary energy is used to provide electricity to buildings. Plug loads play an increasingly critical role in reducing energy use in new buildings (because of their increased efficiencyrequirements), and in existing buildings (as a significant energy savings opportunity). If all installed commercial building miscellaneous electrical loads (CMELs) were replaced with energy-efficient equipment, a potential annual energy saving of 175 TWh, or 35% of the 504 TWh annual energy use devoted to MELs, could be achieved. This energy saving is equivalent to the annual energy productionof 14 average-sized nuclear power plants. To meet DOE's long-term goals of reducing commercial building energy use and carbon emissions, the energy efficiency community must better understand the components and drivers of CMEL energy use, and develop effective reduction strategies. These goals can be facilitated through improved data collection and monitoring methodologies, and evaluation ofCMELs energy-saving techniques.
