Fracture Area Groundwater Survey, Llano, Texas - Case Study
In April 2011, our client had four unsuccessful drilling wells before our company participated in this project at Blackjack Ranch, Llano. After geological analysis, we conducted the seismoelectric survey along the fracture direction and provided our client a well location with 5 gallon/hour water production which proved by later ...

MSITU Raman spectroscopy of cave minerals: an analytical tool compatible with the conservation of subterranean heritage
Introduction: Up to 380 different minerals have been described in caves over the past century [1]. The presence of particular mineral phases has been used as indicators of specific paleoenvironmental conditions occurred in caves [2, 3]. On the other hand, processes involved in the genesis of some cave minerals have been proposed as potential analogs of minerogenetic mechanisms occurred during the ...

Middle Holocene palaeoflood extremes of the Lower Rhine
A Chézy-based hydraulic model was run to estimate the magnitude of extreme floods of Middle Holocene age in the Lower Rhine Valley (Germany). Input parameters were gathered from the field and literature, and used in ten scenarios to calculate a best guess estimate for the minimum size of extreme floods. These events have been registered as slackwater deposits on elevated terrace levels ...

Assessment of raw materials for cement industry in Sohag area, upper Egypt
In the last few years, cement industry become a major player in materials recycling, although it is environmental polluted industry and a great consumer of limestone and clay. Cement manufacturing depends greatly upon chemical and physical characteristics of raw materials, its quality and quantity, simplicity of its extraction and its costs. Sohag Governorate is surrounded by the Eocene ...

A dynamic model using monitoring data and watershed characteristics to project fish tissue mercury concentrations in stream systems
A complex interplay of factors determines the degree of bioaccumulation of Hg in fish in any particular basin. Although certain watershed characteristics have been associated with higher or lower bioaccumulation rates, the relationships between these characteristics are poorly understood. To add to this understanding, a dynamic model was built to examine these relationships in stream systems. The ...

Overview of rare earth metals and intermediate alloys
The vast majority of single rare earth metals and their intermediate alloys are used to produce new rare earth metal materials such as neodymium iron boron, samarium cobalt permanent magnet, and super magnetostriction, and non-ferrous metal alloys such as AI-RE, Mg-RE, Cu-RE, Zn- RE, W-RE, Mo-RE, etc. In addition, there are a few rare earth metal applications that use some special properties to ...

P-METRIX - bringing edxrf lab analysis to the field
The P-Metrix is wrapped in a portable case that acts as a self-contained EDXRF laboratory and allows you to roll it to any site for your elemental analysis test. P-Metrix, bridging new frontiers in lab-to-field analysis, will be presented at the 2017 ACS Spring Meeting, at San Francisco, April 2nd - 4th, booth # 1706. The analytical and industrial instrumentation from Xenemetrix range from ...

A comparison of landscape structure inside and outside the gates: analysis of the regional landscapes of four US Department of Energy facilities using US Geological Survey quadrangle maps and FRAGSTATS
The US Department of Energy (USDOE) facilities encompass large tracts of land that include important regional ecological resources. The historical development and continued operation of these facilities has changed the structure of regional landscapes. A quantitative analysis was performed to determine if patterns of land use within the boundaries of selected USDOE facilities could be ...

Finite element analysis of buried continuous pipeline subjected to fault motion
Pipeline generally extends over long distances traversing through wide variety of different soils, geological conditions and regions with different seismicity. Most analytical models developed in the past for pipeline fault crossing are of limited usage as models developed were useful only for strike slip fault. Incorporating the large geometric changes in analytical study is a tricky task; ...

Risk assessment of land-use suitability and application to Tangshan City
Risk assessment for suitability is one of the main problems in city landuse planning for disaster prevention. Decision-making strategy using GIS-based Ordered Weighted Averaging (OWA) method is discussed through analysing OWA evaluation procedure. Data of geological disaster in Tangshan City are used to calculate the distances from dangerous areas or safety area to yield evaluation criteria for ...

Comparison of phosphorus fraction distribution and influencing factors of suspended and surface sediments in the Tiaoxi watershed, China
Suspended and surface sediments from the Tiaoxi watershed, fed by the Xitiaoxi and Dongtiaoxi rivers, were analyzed for total phosphorus (TP) and the inorganic P fractions of loosely adsorbed P that were extractable with NH4Cl (NH4Cl-P), reductant P (BD-P), metal oxide-bound P extractable with NaOH (NaOH-P), and calcium-bound, HCl-extractable P (HCl-P), while other physicochemical ...

Combining Raman microscopy with scanning electron microscopy (SEM) to study inorganic and mineral samples at the Geological Institute of Romania, Bucharest
The Geological Institute of Romania, located in Bucharest, was founded in 1906. It is famous for its museum which hosts a collection of more than 80,000 samples of rocks, fossils and minerals from all over Romania. Oana-Claudia Barbu and Daniel Bîrgăoanu are both PhD students and research assistants in the electron microscopy laboratory, known as MICROCOSMOS, where they study ...

Sea Level Rise: Risk and Resilience in Coastal Cities
Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself. Unlike some other predicted effects of climate change, this impact has already been observed for some time. Indeed, not only is there ...

Exposure to radon in tourist caves in Cuba
With the objective of estimating the dose due to radon-222 received by tour guides and other people who work inside some of the most important tourist caves in the Republic of Cuba, measurements of radon concentrations were carried out in four of these caves. All the studied caves are located in Vinales Valley (Pinar del Rio City), a very important tourist area in the country. The relationship ...

Assessing ecological risks at US Department of Energy facilities using methods borrowed from landscape ecology and habitat suitability analysis. Part I. Analysis of historical aerial photography and maps
Ecological risks are inherently spatial, and the consideration of scale is critical to all aspects of the ecological risk assessment process. Analysis of alterations in land use and habitat quality and quantity in relation to historical, continuing, and future US Department of Energy (USDOE) operations may be as important as assessing impacts resulting from the release of chemical contaminants ...
