Environmental Contaminants Monitoring In Selected Wetlands Of Wyoming [Biologically Active Elements Study], Pedro Ramirez Jr., Joni Armstrong

United States Fish and Wildlife Service: Publications

Sediment, water and biota were collected from selected wetlands in Wyoming for the Biologically Active Elements (BAE) Study in 1988, 1989 and 1990 to identify contaminant problems that may warrant further study. This report also will assist in developing a comprehensive contaminants monitoring program for the state and will provide baseline contaminants data for wetland areas. Sites surveyed included areas affected by historical and current mining; wetlands receiving oilfield or oil refinery discharges; wetlands receiving irrigation return flows; stock ponds and natural depressions in areas with seleniferous soils and wetlands influenced by urban runoff. Monitoring is recommended for wetlands receiving …

The Last Interglacial-Glacial Transition In North America: Evidence From Uranium-Series Dating Of Coastal Deposits, Daniel R. Muhs

United States Geological Survey: Staff Publications

Considerable uncertainty exists as to whether the last interglacial was relatively "short" (~10 ka) or "long" (-20-60 ka), although most investigators generally agree that the last interglacial correlates with all or part of deep-sea oxygen-isotope stage 5. A compilation of reliable U-series ages of marine terrace corals from deposits that have been correlated with isotope stage 5 indicates that there were three relatively high sea-level stands at ca 125-120 ka, ca. 105 ka, and ca. 85-80 ka, and these ages agree with the times of high sea level predicted by the Milankovitch orbital-forcing theory. At a number of localities, however, …

A Brief Literature Review Of Open-Channel Current Meter Testing, Kirk G. Thibodeaux

United States Geological Survey: Staff Publications

The U.S. Geological Survey (USGS) has undertaken the task of conducting an evaluation of the USGS's standard water-flow current meter, the Price type-AA current meter. The first part of the USGS's task was to conduct a comprehensive literature review to determine the extent and types of testing that has been conducted to evaluate the performance of various types of current meters used for open-channel flow measurements. The meter types included in the review were the vertical-axis mechanical type, the horizontal-axis mechanical type, the electromagnetic type, and the point-velocity acoustic (ultrasonic) type current meters. The review revealed that current meters have …

In Situ Stress Measurements To 3.5 Km Depth In The Cajon Pass Scientific Research Borehole: Implications For The Mechanics Of Crustal Faulting, Mark D. Zoback, John H. Healy

United States Geological Survey: Staff Publications

Measurements of in situ stress orientation and magnitude at the site of the Cajon Pass research borehole have been made from depths of 0.9-3.5 km using the hydraulic fracturing technique and analysis of stress-induced well bore breakouts. The results of these measurements support two important conclusions about the mechanics of crustal faulting. First, the magnitudes of measured in situ stresses indicate ratios of shear to normal stress. on favorably oriented fault planes that are consistent with predictions based on Mohr-Coulomb theory and laboratory-determined coefficients of friction in the range of 0.6-1.0 assuming hydrostatic pore pressure (this is commonly known as …

Stress Field Constraints On Intraplate Seismicity In Eastern North America, Mary Lou Zoback

United States Geological Survey: Staff Publications

Focal mechanisms of 32 North American midplate earthquakes (m_b = 3.8-6.5) were evaluated to determine if slip is compatible with a broad-scale regional stress field derived from plate-driving forces and, if so, under what conditions (stress regime, pore pressure, and frictional coefficient). Using independent information on in situ stress orientations from well bore breakout and hydraulic fracturing data and assuming that the regional principal stresses are in approximately horizontal and vertical planes ( ± 10 °), the constraint that the slip vector represents the direction of maximum resolved shear stress on the fault plane was used to calculate relative …

Mechanism Of Magainin 2a Induced Permeabilization Of Phospholipid Vesicles, Earl Grant, Troy J. Beeler, Kenneth M. P. Taylor, Kenneth Gable, Mark A. Roseman

Uniformed Services University of the Health Sciences

The magainins, peptide antibiotics secreted by the frog Xenopus laevis, have previously been shown to permeabilize phospholipid vesicles. To elucidate the mechanism of permeabilization, we have conducted detailed kinetic studies of magainin 2 amide (mgn2a)hduced release of 6-carboxyfluorescein from vesicles of phosphatidylserine. The results show that dye release occurs in (at least) two stages-an initial rapid phase, with t_1/2 ≈ 3 s, followed by a much slower phase that approaches zero leakage rate before all the dye is released. Light-scattering studies showed that mgn2a does not cause gross changes in vesicle structure. The peptide was found to rapidly …

Flow Impingement Velocities, Snake River, Wyoming, Stephen T. Maynord

United States Army: Publications

Flow impingement, which occurs when approach channels direct flow into a bank line at large acute angles, results in flow concentration along bank lines, which creates large forces on bank material or bank protection. As part of studies conducted to determine the required riprap size for impinged flow, velocities were measured on the Snake River near Jackson, Wyoming. High velocities and steep water-surface slopes were observed at each impingement site.

Revised Hydraulic Design Of The Los Angeles County Flood Control System, Michael E. Mulvihill, Scott E. Stonestreet

United States Army: Publications

The US Army Engineer District, Los Angeles, recently completed a study regarding the adequacy of an existing flood control system in Los Angeles County. Results of this study indicate that the level of protection afforded by the system is as low as 25-year in heavily urbanized areas. The Corps of Engineers plans to increase the capacity in two mainstem channels, raising the level of protection to greater than 1OO-year, by constructing parapet walls on top of existing levees and modifying constrictive bridges. A physical model study will be conducted to aid in analysis of complex design problems and will provide …

Levee/Floodwall Freeboard Design For An Urban Flood Control Project, Daniel B. Pridal, Edward F. Sing

United States Army: Publications

A methodology for the design of levee/floodwall freeboard using evolving guidelines based on the concept of superiority is presented. A case study illustrating the application of the freeboard design guidelines to the Truckee Meadows Project is shown. The Truckee Meadows Project provides a 100 year level of flood protection through the Reno-Sparks, Nevada metropolitan area along an approximate ten mile reach of the Truckee River. Major features of the project include levees, floodwalls, channel modifications, bridge replacement or reconstruction, a detention basin, and drainage improvements. The project is presently in the Preconstruction, Engineering and Design (PED) Phase within the Sacramento …

Removal Of Extremely Low Levels Of Munitions In A Drinking Water Supply, R. Mark Bricka, Wayne Sharp

United States Army: Publications

Past military operations have resulted in the contamination of soils by chemical munitions such as RDX, HMX and TNT (contaminant description, page 2) . The migration of water through the soils can transport the contaminants into groundwater and contaminate drinking water sources . Many military munitions are known or suspected to be carcinogenic and, therefore, must be removed from drinking water .

Analyses Of Special Hazards And Flooding Problems In Tropical Island Environments, Robert C. Macarthur, Douglas L. Hamilton, Michael D. Harvey, Hudson W. Kekaula

United States Army: Publications

Data and results summarized in this paper show that development of urban projects and design of flood control works in tropical island catchments must consider clear water flooding as well as special hazards such as landslides, flow bulking, high sediment concentrations, mud and debris flows and flow avulsions. The needs for and methods to estimate peak flows, event volumes and the potential extent and depths of flooding during severe storm events in urbanizing tropical environments are described.

The Persistence Of Bandhani Production In Barmer, Rajasthan, India, Mary Ann Fitzgerald

Textile Society of America: Symposium Proceedings

In Barmer, Rajasthan, India, traditional alizarin and alizarin-indigo cotton bandhani¹ (tie-dye) garments are produced and distributed to rural populations. The producers of these garments are the Khatri, traditional Hindu dyers and weavers of cotton and silk, while the garments are purchased and worn by Sindhi Muslims and the Hindu Khumbhar women. Thus, the producers and consumers are socially distinct groups. This historical association between producers and consumers has created a tradition of bandhani production that is currently threatened by the introduction of inexpensive screen-printed textiles.

There are two aspects of this traditional bandhani production that may play an important …

Trimmings In Fez Morocco, Frieda Sorber

Textile Society of America: Symposium Proceedings

Decorative finishes are an integral part of textiles in many traditional cultures, both past and present. Unfortunately they have often escaped the attention of textile scholars. Published material on detailed observation in the field is often lacking. However, research into trimmings can give valuable information on technological, social and economical aspects of a culture. The city of Fez is an excellent place to study the production and function of trimmings in an urban setting with a wide variety of crafts¹.

Types of trim made in Fez

Research into trimmings in Fez started with detailed field observation of a …

A Glimpse Of Japanese Dyeing Workshops, Mary V. Hays, Ralph E. Hays

Textile Society of America: Symposium Proceedings

While in Japan in September 1991 we were fortunate to be taken to several small dyeing establishments that make fukusa, furoshiki and kosode. We were most fortunate to have an entre into these establishments because without the proper introduction we would never have been able to make the contacts necessary for an invitation to observe their operation. We were fortunate also in being able to attend a special exhibition of kimono produced by contemporary textile artists. We could not help but be impressed by the cost of these kimono, which are one of a kind works of art. Those …

Hydraulic Risk Of Flood Disaster Reduction At Dams, Shou-Shan Fan

United States Department of Energy: Publications

Floods are major natural hazards, not totally predictable and manageable, at least at the present time. We believe that floods, no matter how violent, need not cause major damage. Loss of lives can be prevented and economic catastrophe minimized if a decision maker has accurate prior information on major flood characteristics, such as the magnitude and arrival time of the flood and its potential damages.
