Administration And Management Of Local Streets And Roads 1988 Volume Ii, Herpicc

Indiana Local Technical Assistance Program (LTAP) Publications

This is Volume II of a two volume handbook that provides local public officials with a guide to technical, environmental, legal and procedural constraints pertaining to local street and road programs in the state of Indiana and provides a comprehensive and usable documented discussion of these subjects. It is based upon an Oregon county road manual published in the early 1980's. Municipal concerns and considerations have been included in addition to those of counties. Volume I is a discussion of ten major topics: local authority; intergovernmental relations; transportation planning; obtaining right-of-way; location, relocation, vacation and railroad abandonment; jurisdictional and functional …

A Rapid, Widely Applicable Screen For Drugs That Suppress Free Radical Formation In Ischemia/Reperfusion, Steven C. Salaris, Charles F. Babbs Jan 1988

A Rapid, Widely Applicable Screen For Drugs That Suppress Free Radical Formation In Ischemia/Reperfusion, Steven C. Salaris, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Substantial injury can occur during reoxygenation of previously ischemic tissue in many experimental models, as the result of the generation of oxygen-derived free radicals. To test the antiradical activity of potentially protective compounds in this setting, we developed a simple screening system, applicable to fresh biopsy specimens, in which warm ischemia and reoxygenation of excised tissue are performed in vitro. Tissue production of malondialdehyde (MDA) equivalents is used as a nonspecific-but-sensitive marker of oxygen radical damage. Test compounds with putative antiradical activity are added prior to the reoxygenation phase, and their ability to suppress MDA production is an index of …

Effects Of Na2s And (Nh4)2s Edge Passivation Treatments On The Dark Current-Voltage Characteristics Of Gaas Pn Diodes, M. S. Carpenter, Michael R. Melloch, M. S. Lundstrom, S. P. Tobin Jan 1988

Effects Of Na2s And (Nh4)2s Edge Passivation Treatments On The Dark Current-Voltage Characteristics Of Gaas Pn Diodes, M. S. Carpenter, Michael R. Melloch, M. S. Lundstrom, S. P. Tobin

Department of Electrical and Computer Engineering Faculty Publications

We have investigated the dark current-voltage characteristics of GaAs pn homojunctions whose surfaces have been passivated with NuzS and (NH4)2S chemical treatments. Reductions in 2kTpcrimeter recombination currents by a factor of 3.2 were obtained for the two treatments. A shunt leakage, observed at low forward bias for the NazS treated devices, is virtually eliminated with the {NH4hS treatment. It is also shown that even the high quality, large area (0.25 cm1 ) pn diodes used in this study are dominated by 2kTedge currents before passivation.


Evidence For Band-Gap Narrowing Effects In Be-Doped, P-P+ Gaas Homojunction Barriers, H. L. Chuang, Paul David Demoulin, M. E. Klausmeier-Brown, Michael R. Melloch, Mark S. Lundstrom Jan 1988

Evidence For Band-Gap Narrowing Effects In Be-Doped, P-P+ Gaas Homojunction Barriers, H. L. Chuang, Paul David Demoulin, M. E. Klausmeier-Brown, Michael R. Melloch, Mark S. Lundstrom

Department of Electrical and Computer Engineering Faculty Publications

The electrical performance of Be‐doped, p‐p+ GaAs homojunction barriers is characterized and analyzed. The results of the analysis show that minority‐carrier electrons, at 300 K, have a mobility of 4760 cm2/V s at a hole concentration of 2.3×1016 cm−3, and that the effective recombination velocity for these homojunction barriers is about 6×104 cm/s. We present evidence that this unexpectedly high recombination velocity is a consequence of an effective reduction in band gap due to the heavy impurity doping. The effective band‐gap shrinkage in this Be‐doped material grown by molecular‐beam epitaxy appears to be comparable to that already …


Effects Of Heavy Impurity Doping On Electron Injection In P+-N Gaas Diodes, M. E. Klausmeier-Brown, Mark S. Lundstrom, Michael R. Melloch, S. P. Tobin Jan 1988

Effects Of Heavy Impurity Doping On Electron Injection In P+-N Gaas Diodes, M. E. Klausmeier-Brown, Mark S. Lundstrom, Michael R. Melloch, S. P. Tobin

Department of Electrical and Computer Engineering Faculty Publications

Measurements of electron injection currents in p+‐n diodes are presented for a range of p‐type dopant concentrations. A successive etch technique was used to characterize the electron injection current in terms of the product (noDn). Measurements are presented for Zn‐doped GaAs solar cells with p‐layer hole concentrations in the range 6.3×1017−1.3×1019 cm−3. The results demonstrate that so‐called band‐gap narrowing effects substantially increase the injected electron current in heavily doped p‐type GaAs. These heavy doping effects must be accounted for in the modeling and design of GaAs solar cells and heterostructure …
