Computer Aided Simulation Of A Heating, Ventilating, And Air Conditioning System In A Building, Sunil Shrikrishna Kulkarni

Mechanical & Aerospace Engineering Theses & Dissertations

The Godwin Life Science Building on the Old Dominion University campus presents an interesting problem in terms of energy conservation. The building is the maximum energy resource consumer on the campus, having a criterion value of 234 KBtu/sq.ft-year (2657 MJoules/sq. rneter-year). A Simplified Energy Analysis Method (ASEAM) loads and systems computer program was used to simulate the building and its heating, ventilating, and air conditioning (HVAC) plant in order to understand the building's high annual energy resource consumption rate, and to devise ways to overcome it. The main goal was to assess and propose energy conservation improvements to the existing …

Writing A Scientific Paper Prior To The Research, Charles F. Babbs, Martha M. Tacker

Weldon School of Biomedical Engineering Faculty Publications

The traditional approach to preparing a research report for publication is to begin writing after the study has been completed. We propose another approach- to write a "zeroth" draft before the study is begun. This approach helps to focus the investigator's attention during the planning stage on critical aspects of the study. The discipline of writing down the rationale, the methods, and the variety of possible outcomes and their significance helps to clarify the logic on which the study is based. If these are acceptable to all authors and colleagues in the zeroth draft, it is likely that the research …

Use Of Combined Systemic Hypothermia And Local Heat Treatment To Enhance Temperature Differences Between Tumor And Normal Tissues, Charles F. Babbs, William D. Voorhees Iii, Robert R. Clark, David P. Dewitt

Weldon School of Biomedical Engineering Faculty Publications

The feasibility of combining local heat treatment with wholebody hypothermia in an effort to improve therapeutic gain was assessed. Superficial, non perfused phantom tumors were fashioned in eight anesthetized mongrel dogs by transplantation of the spleen from the abdomen to a subcutaneous site on the hind limb. After pretreatment of the animal with the vasodilator hydralazine (0.5 mg/kg, IV) to enhance normal tissue perfusion, the spleen implant was heated with a 2450-MHz microwave diathermy apparatus, first with the animal's core body temperature in the normal range (39°C) and then after the animal had been packed in ice to reduce core …

Endotracheal Versus Intravenous Epinephrine During Electromechanical Dissociation With Cpr In Dogs, Sandra H. Ralston, Willis A. Tacker, Lee Showen, Alice B. Carter, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

The dose-response curves of epinephrine given either IV or endotracheally (ET) were compared during resuscitation from electromechanical dissociation (EMD). Ten anesthetized dogs were subjected to a two-minute period of electrically induced ventricular fibrillation (VF) followed by defibrillation without CPR to produce EMD. Mechanical CPR was followed by injection of either ET or IV epinephrine. Successful response was defined as a return of pulsatile blood pressure within two minutes of drug administration. Using log-dose increments of epinephrine, experimental trials were repeated in each animal. The IV and ET median effective doses were 14 and 130 g/kg, respectively. When the trials were …

Gastric Insufflation During Iac-Cpr And Standard Cpr In A Canine Model, Charles F. Babbs, William E. Schoenlein, Marc W. Lowe

Weldon School of Biomedical Engineering Faculty Publications

This study was undertaken to determine the effect of interposed abdominal compressions (IAC) during cardiopulmonary resuscitation (CPR) on gastric insufflation when the airway is not secured with an endotracheal tube. A canine model was used in which a common ventilation pressure was applied to separate cuffed esophageal and tracheal tubes. Gas entering the stomach was collected by a pre-placed gastrostomy tube leading to a bell spirometer. Gas entering the lungs was measured with a Wright Respirometer® in series with the endotracheal tube. During standard CPR, measurable gastric gas volume was collected in 28 of 30 trials (mean 215  93 …

Electroventilation, L A. Geddes, William D. Voorhees, Charles F. Babbs, J A. Deford

Weldon School of Biomedical Engineering Faculty Publications

Electroventilation is a term used to describe the production of inspiration by applying rhythmic bursts of short duration stimuli to extrathoracic electrodes to stimulate motor nerves to the inspiratory muscles. In the dog, the optimum site for the electrodes was found to be on the upper chest wall, bilaterally. The inspired volume increased with increasing current intensity. The maximum tidal volume attainable was about four times resting tidal volume. The ability of electroventilation to maintain arterial blood oxygen saturation without the production of cardiac arrhythmias was demonstrated in pentobarbital-anesthetized dogs. The technique has several potential applications and offers promise in …

Joseph S. Redding's Contributions To Cardiac Resuscitation, Sandra H. Ralston, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

The experimental studies conducted by the late Joseph S. Redding over the past three decades with his students and colleagues form the scientific basis for many aspects of present cardiopulmonary resuscitation (CPR). Redding's research was characterized by its elegance, simplicity, common-sense reasoning, and clinical relevance. Much of his work conducted in the 1960's anticipated with uncanny accuracy some of the most actively discussed issues in resuscitation today (Table 1). Most interesting are Redding's classic studies related to diastolic arterial pressure and myocardial perfusion during CPR, abdominal binding, acid-base status, and use of methoxamine versus other adrenergic drugs for cardiac resuscitation. …

Soil Compaction I Where, How Bad, A Problem, Elbert C. Dickey, Thomas Peterson, Dean E. Eisenhauer, Paul J. Jasa

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Soil compaction is a more common problem now than it was 15 years ago, regardless of the tillage system used. Producers now use heavier tractors, larger implements, bigger combines, earlier spring tillage, reduced tillage, and no-till planting systems.

While all of these have a potential to increase compaction, the major cause of the problem is conducting field operations when the soil is too wet. Most think about tilling wet soils in the spring as being the major problem, but harvesting a too-wet field in the fall can cause just as much compaction. Large combines and auger wagons can have loads …

Evaluation Of A Near-Surface Low-Level Radioactive Waste Disposal Facility For The State Of Missouri, Christine Lang Nelson

Masters Theses

"A low-level radioactive waste disposal facility for the state of Missouri Is designed. The proposed facility Is to be placed in a mined opening within a Precambrian granite outcrop in southeastern Missouri.

A safety assessment of the proposed facility was performed. The method used was fault tree analysis.

The threat of seismic activity within the region ls seen to be the main determent to the proposed design. Groundwater modelling was not possible due to a lack of data.

The facility design Includes a provision for the retrieval of the low-level waste once the waste has decayed to acceptable levels"-- Abstract, …

Irradiation-Hyperthermia In Canine Hemangiopericytomas: Large-Animal Model For Therapeutic Response, Ralph C. Richardson, Virgil L. Anderson, William D. Voorhees, William E. Blevins, Tammy K. Inskeep, Wolfgang Janas, Robert E. Shupe, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Results of irradiation-hyperthermia treatment in 11 dogs with naturally occurring hemangiopericytomas are reported. Similarities of canine and human hemangiopericytomas are described. Orthovoltage X-irradiation followed by microwaveinduced hyperthermia resulted in a 91% objective response rate. A statistical procedure was given to evaluate quantitatively the clinical behavior of locally invasive, nonmetastatic tumors in dogs that were undergoing therapy for control of local disease. The procedure used a small sample size and demonstrated distribution of the data on a scaled response as well as transformation of the data through classical parametric and nonparametric statistical methods. These statistical methods set confidence limits on the …

Microbial Characteristics Of An Activated Sludge And Three Commercial Preparations After Exposure To Phenolics, Laurie Gneiding

Theses

The biological characteristics of four microbial mixtures were examined after successive exposure to phenol and 2-chlorophenol at room temperature. One of the microbial mixtures was an activated sludge from the Livingston, NJ municipal wastewater treatment plant. The other three mixtures were commercial preparations sold by Polybac Corp.(Hydrobac), Sybron Corp. (BI-CHEM DC 1006/1007), and General Environmental Sciences(LLMO).

The characteristics examined were relative counts and species of gram negative/gram positive bacteria, yeast and fungi, protozoa, and higher organisms. For the gram negative bacteria and yeasts, culturing techniques and diagnostic tubes were used to determine the predominant species. Biochemical tests were done on …

A Study Of The Effect Of Solids, Viscosity, And Basestock On The Development Of Blade Coated Paper Properties, Steven D. Bennett

Masters Theses

A review of literature relating coating solids to coated paper properties revealed many contradictions. Little was found relating coating viscosity to coated paper property development. A statistically designed study was conducted to evaluate the importance of solids, viscosity, and basestock on the development of blade coated paper properties. Temperature was used to control coating viscosity independently of solids. Clay-latex and calcium carbonate-latex coatings were applied to groundwood containing basestocks using a Flooded Nip blade coater. Multiple linear regression models were generated for each of the coated paper properties. Solids and basestock were most important in the models for gloss, smoothness, …
