The Effect Of Potassium Permanganate On The Removal Of Iron And Manganese From Ground Water, Mohammad Reza Farvardin

Electronic Theses and Dissertations

For the past three years or so, a gradual migration of iron and manganese deposits has been observed in the water mains to the west of the East Water Treatment Plant of Brookings, South Dakota. These deposits have been gradually migrating further westward from the plant (8). Routine analyses of the treated water from the East Plant indicate that the iron and manganese levels are within the USPHS recommended limits (9). Consequently, conclusive evidence that this plant is the source of the problem does not exist. However, the analyses are normally conducted on samples collected shortly before backwashing the filters. …

Effect Of Pentobarbital Anesthesia On Ventricular Defibrillation Threshold In Dogs, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

The effect of pentobarbital anesthesia upon the minimal voltage and current required for electrical ventricular defibrillation (the defibrillation threshold) was investigated in dogs. Threshold current, energy, and charge in five dogs averaged 2 per cent, 13 per cent, and 6 per cent less under surgical levels of pentobarbital anesthesia than thresholds in the same animals in the awake, unanesthetized state. In dogs given sufficient pentobarbital to produce apnea and supported by mechanical ventilation, threshold current, energy, and charge averaged 3 per cent, 17 per cent, and 2 per cent less than comparable awake values. These differences were far from statistically …

Energy Conservation In Buildings -- The Missouri Plan, Jack Whittier, Bill Jurkiewicz, Weston Fisher

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In 1974, approximately 23 percent (256.5 trillion Btu's) of Missouri energy was consumed in the residential sector. In 1980, this figure is projected to be 246.6 trillion Btu's (21 percent) (ref. 1). The reduction reflects already implemented conservation activities and the increased use of electric heating at higher end point efficiency. Estimates suggest that energy savings of nearly 50 percent could be achieved in this sector, primarily by upgrading the thermal efficiency of building structures and changing user behavior patterns. This given potential, the reduction of energy consumption in this sector has become a major target of the Missouri Energy …
