Wage Survey Of Road And Street Employees In Indiana Counties And Cities, Herpicc
Wage Survey Of Road And Street Employees In Indiana Counties And Cities, Herpicc
Indiana Local Technical Assistance Program (LTAP) Publications
Wages, benefits and insurance plans for employee classifications common to road and street maintenance organizations are reported in this publication. The figures were obtained from a March 1988 questionnaire sent to all Indiana County Highway Departments and from the "Indiana Municipal Salaries, Wages and Fringe Benefits, 1988" published by the Indiana Association of Cities & Towns.
The information in this publication is intended to assist the local road and street agencies in developing the wage plans for next years budget by providing comparative information from other organizations in the state. Exact duties and responsibilities vary and are not reflected in …
Guide To Revenue Calculations: Local Option Highway User Tax 1988, Herpicc
Guide To Revenue Calculations: Local Option Highway User Tax 1988, Herpicc
Indiana Local Technical Assistance Program (LTAP) Publications
This guide is provided to explain the output generated by the computer programs and to suggest ways in which the results can be adapted to specific LOHUT proposals before a County Council. The 1988 LOHUT revenue projections are of special interest because of House Enrolled Act Number 1295. This act (IC 8-11-5) granted each county authority to bond for county roads or bridges, but only if a county has first adopted a LOHUT -- the excise surtax (IC 6-3.5-4) and wheel tax (IC 6-3.5-5).
HERPICC neither endorses nor opposes passage of a LOHUT. The revenue projections it provides are intended …
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
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
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 …
Myocardial Perfusion Pressure: A Predictor Of 24hour Survival During Prolonged Cardiac Arrest In Dogs, Karl B. Kern, Gordon A. Ewy, William D. Voorhees, Charles F. Babbs, Willis A. Tacker
Myocardial Perfusion Pressure: A Predictor Of 24hour Survival During Prolonged Cardiac Arrest In Dogs, Karl B. Kern, Gordon A. Ewy, William D. Voorhees, Charles F. Babbs, Willis A. Tacker
Weldon School of Biomedical Engineering Faculty Publications
Myocardial perfusion pressure, defined as the aortic diastolic pressure minus the right atria1 diastolic pressure, correlates with coronary blood flow during cardiopulmonary resuscitation (CPR) and predicts initial resuscitation success. Whether this hemodynamic parameter can predict 24-h survival is not known. We examined the relationship between myocardial perfusion pressure and 24-h survival in 60 dogs that underwent prolonged (20 min) ventricular fibrillation and CPR. Forty-two (70%) animals were initially resuscitated and 20 (33%) survived for 24 h. Myocardial perfusion pressure was significantly greater when measured at 5, 10, 15 and 20 min of ventricular fibrillation in the resuscitated animals than in …
A Rapid, Widely Applicable Screen For Drugs That Suppress Free Radical Formation In Ischemia/Reperfusion, Steven C. Salaris, Charles F. Babbs
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 …

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 General Ordinance Establishing Storm Drainage Control, Herpicc
A General Ordinance Establishing Storm Drainage Control, Herpicc
Indiana Local Technical Assistance Program (LTAP) Publications
The preparation of this model drainage ordinance was the result of numerous meetings by a committee composed of County Commissioners, County Engineers, County Surveyors, and representatives of the Indiana Department of Natural Resources, and Indiana Department of Highways. The goal of this group was to formulate a drainage ordinance that could be adapted by Indiana counties to satisfy the counties' needs for reasonable drainage control, the current state of engineering practice and reasonable engineering standards. The group began with the experience of counties in Indiana which had already adopted some form of drainage control policy. Through numerous modifications and additions, …
