Handbook Of Traffic Control Practices For Low-Volume Roads In Indiana, Herpicc
Handbook Of Traffic Control Practices For Low-Volume Roads In Indiana, Herpicc
Indiana Local Technical Assistance Program (LTAP) Publications
The purpose of the Handbook on Traffic Control Practices for Low Volume Roads in Indiana is to provide a guide to supplement the existing Manuals on Uniform Traffic Control Devices (MUTCD ). Both the National and the Indiana MUTCDs provide general guidelines for the design, installation, and use of traffic control devices (signs, signals, and markings) on all roads and streets, but their main concern is with higher volume highways. Neither specifically addresses the operational and guidance problems associated with roads that carry fewer than 400 vehicles per day. This handbook's intent is to make these low volume roads safer …

An Experimental Circulatory Arrest Model In The Rat To Evaluate Calcium Antagonists In Cerebral Resuscitation, Lawrence De Garavilla, Charles F. Babbs, Willis A. Tacker
An Experimental Circulatory Arrest Model In The Rat To Evaluate Calcium Antagonists In Cerebral Resuscitation, Lawrence De Garavilla, Charles F. Babbs, Willis A. Tacker
Weldon School of Biomedical Engineering Faculty Publications
A circulatory arrest model in the rat was developed for use in cerebral and cardiac resuscitation studies. Whole-body ischemia was produced for 8 to 18 minutes by arresting the heart with a cold potassium chloride cardioplegic solution. Following cardiopulmonary resuscitation, minimal, standardized intensive care was provided. As the duration of ischemia was increased from 8 to 18 minutes, survival immediately following resuscitation decreased from 100% to 25%, and survival at 48 hours after ischemia decreased from 80% to 0%. Thirty per cent of the rats recovering from 11 minutes of ischemia suffered motor seizures. Survival and the incidence of motor …
Preclinical Studies Of Abdominal Counterpulsation In Cpr, Charles F. Babbs
Preclinical Studies Of Abdominal Counterpulsation In Cpr, Charles F. Babbs
Weldon School of Biomedical Engineering Faculty Publications
Abdominal counterpulsation added to standard cardiopulmonary resuscitation improves blood flow in animal models when compared to chest compressions alone. Similar effects can be demonstrated in analog and digital computer models of the circulation. The technique generates both central aortic and central venous pressure pulses, and successful application of the method depends on maximizing the former and minimizing the latter. Proper technique is important in order to generate the largest possible arteriovenous pressure difference.

Abnormal Response Of Tumor Vasculature To Vasoactive Drugs, Rosanna C. Chan, Charles F. Babbs, Richard J. Vetter, Carlton H. Lamar
Weldon School of Biomedical Engineering Faculty Publications
The effects of the vasoconstrictor, phenylephrine, and the vasodilator, hydralazine, on blood flow to tumor were studied and compared to those on blood flow to normal tissues in vivo. Regional blood flow and cardiac output were measured with the use of radioactive microspheres in 150- to 250 g inbred Harlan F344 rats bearing subcutaneous nodules of two types of transplantable carcinoma ("hard" and "soft") with microscopically different vascular patterns. Three groups of rats were treated with hydralazine, saline, or phenylephrine, and regional blood flow was determined at the time of maximum blood pressure response. Results were correlated with quantitative morphometric …
Cardiac, Thoracic, And Abdominal Pump Mechanisms In Cardiopulmonary Resuscitation: Studies In An Electrical Model Of The Circulation, Charles F. Babbs, Christopher Weaver, Sandra H. Ralston, Leslie A. Geddes
Cardiac, Thoracic, And Abdominal Pump Mechanisms In Cardiopulmonary Resuscitation: Studies In An Electrical Model Of The Circulation, Charles F. Babbs, Christopher Weaver, Sandra H. Ralston, Leslie A. Geddes
Weldon School of Biomedical Engineering Faculty Publications
To investigate alternative mechanisms generating artificial circulation during cardiopulmonary resuscitation (CPR), an electrical model of the circulation was developed. Heart and blood vessels were modeled as resistive-capacitive networks; pressures in the chest, abdomen, and vascular compartments as voltages; blood flow as electric current; blood inertia as inductance; and the cardiac and venous valves as diodes. External pressurization of thoracic and abdominal vessels, as would occur in CPR, was simulated by application of half-sinusoidal voltage pulses. Three modes of creating artificial circulation were studied: cardiac pump (CP), in which the atria and ventricles of the model were pressurized simultaneously; thoracic pump …

Weldon School of Biomedical Engineering Faculty Publications
Blood flow to vital organs was measured at five-minute intervals during 20 minutes of cardiopulmonary resuscitation (CPR) and ventricular fibrillation in two groups of anesthetized dogs (n = 15 per group). The relationship between organ blood flow and restoration of circulation after 20 minutes was assessed with no additional treatment in Group I and with intrapulmonary epinephrine in Group II. Cardiac output and organ blood flow did not vary significantly in Group I. In Group II, intrapulmonary epinephrine significantly improved blood flow to the myocardium, the brain, and the adrenal glands. A mean myocardial blood flow of less than 0.13 …

Weldon School of Biomedical Engineering Faculty Publications
Animal studies and preliminary clinical observations suggest that the addition of interposed abdominal compressions (IAC) to ventilation and chest compression of standard cardiopulmonary resuscitation (CPR) augments blood flow, blood pressures, and immediate survival. To investigate the physical basis for enhanced circulation during IAC-CPR, we developed an electrical model of the circulation. Heart and blood vessels were modeled as resistive-capacitive networks, pressures as voltages, blood flow as electric current, blood inertia as inductance, and the cardiac and venous valves as diodes. External pressurization of the heart and great vessels, as would occur in CPR, was simulated by application by half-sinusoidal voltage …

Louis XIV during the fifty-five years of his personal reign (1661-1715) created the institutional foundations for the science and technology of France. These institutions were outwardly an attempt both to meet the needs of the French state for technical advice and to provide professional scientists with the necessary support for pure scientific research. In a less obvious sense, the origin and evolution of these institutions represented an attempt on the part of the monarchy to disentangle the pursuit of knowledge from the prevailing system of political patronage and from the political and religious speculation that fed the social conflicts of …
