Hydrothermal mineralization and alteration at the Globe Hill deposit, Cripple Creek district, Colorado
The Globe Hill deposit is hosted by a porphyritic, subvolcanic intrusive which is composed of pyroxene-bearing alkali trachyte. It is emplaced within the Oligocene-age Cripple Creek diatreme-intrusive complex, which may ... -
Geology, mineralization, and fluid inclusion analysis of the Ajax vein system, Cripple Creek, Colorado
The Ajax mine is located in the Cripple Creek mining district. Teller County, Colorado. Mine workings extend through a vertical range of 3363 feet (1025 m), from 10,105 feet (3081 m) to 6742 feet (2055 m) elevation. ... -
Structural geology and tectonic setting of the Cherry Creek Metamorphic Suite, Southern Madison Range
The Cherry Creek Metamorphic Suite, exposed in the core of the southern Madison Range in the northwestern Wyoming province, is a well-preserved, carbonate-quartzite-pelite shelf association of Archean age containing a ... -
Geology of the Taylor Silver deposit, White Pine County, Nevada
The Taylor silver mine is located 15 miles southeast of Ely, Nevada, on the western flank of the Southern Schell Creek Range. The 1200 ton per day open pit mine produces up to 1,200,000 ounces silver and 1000 ounces gold ... -
Germination, emergence, and seed persistence of Panicum miliaceum L.
The effects of varying levels of temperature, moisture, and seed depth on wild proso millet (Panicum miliaceum L.) emergence were observed. The effects of depth and duration of seed burial and the effects of seed overwintering ... -
Dairy farm phosphorus recovery and re-use to reduce water quality risk and improve phosphorus cycling in agriculture
Phosphorus (P) is a limited natural resource, and its efficient use and cycling are important for the long-term sustainability of agricultural and industrial production. The over-application of P in dairy wastewater to ... -
Validity and reliability of a test of environmental supportiveness
Through playful interactions with people and objects an individual gains valuable knowledge about the world around them. These interactions are also crucial to nurturing play. Research shows the most prominent features of ... -
Use of remote sensing to estimate soil salinity and evapotranspiration in agricultural fields
In recent years, methods for detecting soil salinity have improved greatly. This research describes methods to detect soil salinity levels in agricultural lands based on crop conditions and evapotranspiration (ET) using ... -
Factors controlling soil spatial variability in a native range landscape
Soils were characterized along three transects of the same catenary sequence within the semi-arid shortgrass (Bouteloua gracilis) steppe of north central Colorado. The objectives of the study were to: 1. Evaluate which ... -
Multi-level code comprehension model for large scale software, A
For the past 20 years researchers have studied how programmers understand code they did not write. Most of this research has concentrated on small-scale code understanding. We consider it necessary to design studies that ... -
Rater goals as a function of appraisal purpose and ratee performance level
The goals raters have in mind when evaluating employee performance has not been a central area of focus in traditional performance appraisal literature (Cleveland & Murphy, 1992; Murphy and Cleveland , 1991). The purpose ... -
Known discharge uncoupled sediment routing
A known discharge, uncoupled, sediment routing model, KUWASER has been developed. The model sequentially solves the steady flow and sediment continuity equations. This procedure allows for efficient solution of sediment ... -
Solute transport by a volatile solvent
Reclamation and impact analysis of retorted oil shale piles will require prediction of water and solute transport rates over the entire solution content range, down to and including the relatively dry region. In such dry ... -
Structural evolution of the gold quarry deposit and implications for development, Eureka County, Nevada
The Gold Quarry deposit, located seven miles north of Carlin, Nevada, is a bulk-minable sediment-hosted disseminated gold deposit situated along the Carlin Trend in Eureka County. A premier gold deposit in North America, ... -
Experiences of at-risk adolescent girls in group therapy, cofacilitated by a psychotherapist and music therapist : a pilot study, The
This study bridges the gap between psychotherapy and music therapy. Based on the experiential essence of musical interventions, it is hypothesized that the inclusion of music therapy in the context of adolescent group ... -
Measuring changes in areal extent of historic wetlands at Great Sand Dunes National Monument, Colorado 1936-1995
Great Sand Dunes National Monument (GRSA) is a unit of the National Park system in south central Colorado. With funding from the Colorado Historical Society, a series of studies were undertaken for an environmental history ... -
Frazier Site : an agate basin occupation and lithic assemblage on the Kersey Terrace, northeastern Colorado, The
The Frazier site was discovered by Frank Frazier in 1965, and was excavated from 1965 to 1967 by the Denver Museum of Natural History under the direction of H. Marie Wormington. An analysis of the lithic assemblage and a ... -
Precipitating convective cloud downdraft structure : a synthesis of observations and modeling
This study represents a comprehensive investigation in which observations are integrated with three-dimensional cloud model results to examine the kinematic, dynamic and thermodynamic structure of downdrafts associated ... -
Cloud-to-ground lightning polarity and environmental conditions over the central United States
The majority of cloud-to-ground (CG) lightning across the United States lowers negative charge to the ground. However, recent studies have documented storms that produce an abundance of positive CG lightning. These positive ...
