An In Vitro Study Comparing The Conventional Step-Back Instrumentation Technique To A Combination Step-Back/Ultrasonic Technique, James A. Eberhardt

Loma Linda University Electronic Theses, Dissertations & Projects

Cleaning and shaping the root canal system is an important phase of endodontic therapy, and must be performed thoroughly and completely if successful root canal therapy is to be expected. A number of investigators have compared different methods of cleaning and shaping of the root canal system. The purpose of this study was to compare the effectiveness of the conventional step-back technique with that of a combination step-back/ultrasonic technique. This combination technique is a modification of the conventional step-back technique using an ultrasonic instrument alternately with hand instrumentation. Utilizing 40 canals from extracted human mandibular molar teeth with a curvature …

Remote Detection Of Coral 'Bleaching' Using Pulsed-Laser Fluorescence Spectroscopy, J. T. Hardy, F. E. Hoge, J. K. Yungel, Richard E. Dodge

Marine & Environmental Sciences Faculty Articles

Despite their biological and economic importance coral reefs are increasingly threatened by human activities. Recently, 'bleaching' of reefs, i.e. loss of photosynthetic pigmentation, has occurred at numerous globally-distributed sites. A number of environmental stressors, including increased water temperature, can induce bleaching. Several investigators have suggested that the widespread occurrence of coral bleaching represents an early warning signal of global greenhouse warming. Regardless of the cause, the extent of coral bleaching, both regionally and globally, needs to be documented and monitored. We conducted laboratory studies to evaluate the potential of using remotely-sensed laser-induced fluorescence to monitor coral pigmentation. Five species of …

Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation

Publications (WR)

Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments. While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …

Bacterial Biosorption Of Heavy Metals From Liquid Wastestreams, Emilia Rus

Theses

In this study, immobilized activated sludge from a municipal wastewater aerobic treatment plant has been evaluated as a potential biosorbent for the removal of heavy metals from liquid waste streams. The method of immobilization consists of entrapment of the microorganisms in calcium alginate beads.

The affinity of immobilized activated sludge to cadmium, lead, chromium and copper has been evaluated under well defined laboratory conditions.

Initially, the time course of metallic ions uptake and the effect of pH and temperature on biosorption were studied for each metal. Then the biosorption pattern and the effect of biosorbent concentration on binding capacity were …

Determination Of Pentachlorophenol In Wood And Leachate From Discarded Treated Wooden Poles, Yan Zha

Theses

Pentachlorophenol(PCP) has long been used as a preservative in the wood industry. The disposal of the used treated wood poles in landfill is of an environmental concern.

The study presented in this paper was designed to determine the leaching of pentachlorophenol from treated aged wood. An analytical method for HPLC determination of PCP was developed and validated to perform the analysis of pentachlorophenol in samples of the oringinal wood and leaching solutions.

Further studies involved the description of the PCP distribution in wood poles, the estimation of the leaching rate of PCP and the factors which influence the leaching rate …

Beryllium 7 And Lead 210 In The Western Hemisphere Arctic Atmosphere: Observations From Three Recent Aircraft-Based Sampling Programs, Jack E. Dibb, R. Talbot, G L. Gregory

Earth Sciences

Concentrations of the natural radionuclides ⁷Be and ²¹⁰Pb were determined in aerosol samples collected in the western hemisphere Arctic during the recent NOAA Arctic Gas and Aerosol Sampling Program (AGASP 3) and NASA Global Tropospheric Experiment/Arctic Boundary Layer Expeditions (GTE/ABLE 3A and ABLE 3B) missions. Beryllium 7 showed a free tropospheric concentration maximum between 4 and 5 km in the summer of 1990. Previous ⁷Be data obtained in the late 1950s and early 1960s also indicated a similar vertical distribution of ⁷Be near 70°N. Injection of stratospheric air through tropopause folds associated with the Arctic jet …

Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong

Arkansas Water Resources Center Technical Reports

The Arkansas Agricultural Chemical Ground-Water Management Plan (SMP) is based on the Draft State Pesticide Ground- Water Management Plan Guidance and The Pesticides and Ground-Water Protection Strategy prepared by the U.S. Environmental Protection Agency (EPA). The need for a plan to protect ground water from contamination by agricultural chemicals and agents arises from evidence nationwide that using these chemicals can, in some instances, lead to contamination. In February 1988, EPA proposed a strategy to regulate certain pesticides by prohibiting their use in areas vulnerable to leaching unless a state develops and implements an acceptable management plan. The advantage of a …

Interferences Of N-Chloroorganic Compounds In Free Chlorine Determination, Sushma H. Gandhi

Chemistry & Biochemistry Theses & Dissertations

Various N-chlorinated organic compounds give positive responses to the analytical methods used to determine free chlorine. The present work quantifies interferences due to N-chloroisoleucine, N-chloropiperidine and N-chloro-2-methylbutyraldiminein the free chlorine determination by amperometry. These N-chloroorganic compounds were also studied for the recovery in response by the indicator electrode in amperometric titrimetry. The total chlorine content of the chloroaldimines derived from the chlorination of the amino acids, alanine, glutamic acid, glycine, isoleucine, leucine, phenylalanine, serine, valine, and those of dipeptides, alanylvaline and glycylleucine, was determined by amperometry and DPD-FAS titrimetry. The two methods were compared and evaluated with respect to recovery …

The Boston Harbor Cleanup, Paul F. Levy, Michael S. Connor

New England Journal of Public Policy

Boston Harbor earned a widespread reputation as "the dirtiest harbor in the nation" during the 1988 presidential campaign. Well before that campaign began, though, efforts were under way to reduce the amount of pollution entering the harbor. The Massachusetts Water Resources Authority was created in 1985 to undertake a massive public works program — including construction of a 1.3 billion-gallon-per-day sewage treatment plant and a sludge fertilizer processing plant — to end the decades-old practice of dumping sewage wastes into the ocean. The program will also cause water and sewer charges to rise dramatically during a fifteen-year period.

The Structure Of A Complex Of Bovine &-Thrombin And Recombinant Hirudin At 2.8-A Resolution, Jacqueline Vitali, Philip D. Martin, Michael G. Malkowski, William D. Robertson, Jerome B. Lazar, Richard C. Winant, Paul H. Johnson, Brian F.P. Edwards

Physics Faculty Publications

Crystals of the complex of bovine alpha-thrombin with recombinant hirudin variant 1 have space group C222(1) with cell constants a = 59.11, b = 102.62, and c = 143.26 A. The orientation and position of the thrombin component was determined by molecular replacement and the hirudin molecule was fit in 2 magnitude of Fo - magnitude of Fc electron density maps. The structure was refined by restrained least squares and simulated annealing to R = 0.161 at 2.8-A resolution. The binding of hirudin to thrombin is generally similar to that observed in the crystals of human thrombin-hirudin. Several differences in …
