Las cruces del olvido. Directory of Open Access Journals Sweden. Street, Las CrucesNM, Persons who use a telecommunications device for the deaf Manager, updates on ongoing issues and planning efforts, presentation on the TriCounty Resource Management Modeling testing at the Las Cruces Trench Site. Several field experiments have been performed by scientists from the University of Arizona and New Mexico State University at the Las Cruces Trench Site to provide data tc cryces deterministic and stochastic models for water flow and solute transport.
These experiments were performed in collaboration with INTRAVAL, an international effort toward validation of geosphere models for the transport of radionuclides. Detailed quantitative comparisons were not made. To provide data for more rigorous model testing, ejerciccios third Las Cruces Trench experiment was designed by scientists from the University of Arizona and New Mexico State University.
The corresponding models assumed soil characterizations ranging ejerrcicios uniform to deterministically heterogeneous to stochastic. This report presents detailed quantitative comparisons to field data.

It is organized basically from two moments: The second one constitutes an initial proposal of interpretation and explanation of the changes in the financing of the activities, trying to answer two questions: We present the results for over two decades of monitoring on intertidal food-gatherers and the population of the low rocky shore dweller kelp Durvillaea antarctica, a short-distance disperser, inside and outside the no-take marine reserve, Estacion Costera de Investigaciones Marinas ECIMat Las Crucescentral Chile.
It was hypothesized that protection of an initially extremely depleted population would recover by recolonizing first the no-take area and then adjacent non-protected exploited areas. We found that recovery of D. These results suggest that the kelp population inside ECIM was likely regulated via intraspecific competition, which did not occur outside. Results showed no evidence for juvenile vs. These findings also suggest that the population recovery and cross-boundary seeding subsides affected the population dynamics.
Understanding these dynamics may enhance management and conservation policies. Our work highlights the critical value of baseline and long-term comparative studies in marine no-take protected and non-protected areas for understanding how population processes respond to human and conservation practices.
Flow and transport at the Las Cruces crucee site: Three water flow and solute transport experiments were performed as part of a comprehensive field trench study near Las CrucesNew Mexico to test deterministic and stochastic models of vadose zone flow and transport. This report presents cruce results from the third experiment experiment IIb. Experiments IIa and b were conducted on the North side of the trench, on a plot 1. The area was drip irrigated during two time periods with water containing a variety of tracers.
The advance of the water front during the two irrigation episodes was measured with tensiometers and neutron probes.
Solute front positions were determined from soil solution sampling through suction samplers and from disturbed sampling. The results from experiment IIb show predominantly downward water movement through the layered unsaturated soil, as evidenced from neutron probe data and gravimetric sampling. Tritium plumes were only half as deep and half as wide as the water plumes at days after the beginning of experiment IIb.
Chloride and nitrate, initially present at high concentrations in the soil solution, were displaced by the low concentration irrigation water, resulting in chloride and nitrate concentration distributions that looked like negative images of the tritium distributions.
The extensive data presented should serve well dihibbridos a data base for model testing. The Las Cruces deposit has sparked an interest in the scientific community due to the exceptional genesis and mineralogical composition.
The original gossan formed by ejerciciso and hematite has been replaced by siderite and galena rock. The current gossan composition is as the result of the interaction of groundwater that circulates through the Niebla-Posadas aquifer and a gossan formed by Fe-oxyhydroxides. The groundwater conditions promoted the reductive dissolution of Pb-bearing goethite by the organic matter degradation and the formation of siderite and galena. Hydrochemical and isotopic characteristics of groundwater endorses this hypothesis.
Thus, negative Eh values, the existence of H2S and the tendency to light sulfate isotope values show the reducing conditions of groundwater. The objective of this work was to test the ability of the PORFLO-3 computer code to simulate water infiltration and solute transport in dry soils. Data from a field-scale unsaturated fihibridos flow and transport experiment, conducted near Las CrucesNew Mexico, were used for model validation.
A spatial moment analysis was used to provide a quantitative basis for comparing the mean simulated and observed flow behavior. The scope of this work was limited to two-dimensional simulations of the second experiment at the Las Cruces trench site.
Three simulation cases are presented. The first case represents a uniform soil profile, with homogeneous, isotropic hydraulic and transport properties. The second and third cases represent single stochastic realizations of randomly heterogeneous hydraulic conductivity fields, generated from the cumulative probability distribution of the measured data.
Two-dimensional simulations produced water content changes that matched the observed data reasonably well. Models that explicitly incorporated heterogeneous hydraulic conductivity fields reproduced the characteristics of the observed data somewhat better than a uniform, homogeneous model.
Improved predictions of water content changes at specific spatial locations were obtained by adjusting the soil hydraulic properties. However, the results of this study demonstrate the importance of site-specific data for model calibration. Applications of the code for waste management and remediation activities will require site-specific data for model calibration before defensible predictions of unsaturated flow and containment transport can be made.

Emercicios processes have usually been identified and evaluated using qualitative or semiquantitative geochemical or isotopic tools based on a restricted number of variables. However, a more complete and quantitative view could be reached applying multivariate analysis, mass balance techniques, and statistical tests. As an example, in this work a statistical and quantitative scheme is applied to analyze the geochemical features for the Sierra de ejercicips Cruces SC volcanic range Mexican Volcanic Belt.
In this locality, the volcanic activity 3.
New discriminant-function-based multidimensional diagrams were used to discriminate tectonic setting. Statistical tests of discordancy and significance were applied to evaluate the influence of the subducting Cocos plate, which seems to be rather negligible for the SC magmas in relation to several major and trace elements. A cluster analysis following Ward’s linkage rule was carried out to classify the SC volcanic rocks geochemical groups. Finally, two mass-balance schemes were applied for the quantitative evaluation of the proportion of the end-member components dacitic and andesitic magmas in the comingled lavas binary mixtures.

The LCT experiments were specifically designed to test various deterministic and stochastic models of water flow and solute transport in heterogeneous, unsaturated soils. Experimental data from the first tow LCT experiments, and detailed crucfs characterisation studies provided information for developing and calibrating the models.
Experimental results from the third experiment were held confidential from the modellers, and were used for model comparison. These analyses indicated that no model, whether uniform or heterogeneous, proved superior.
Since the INTRAVAL study, however, a new method has been developed for conditioning the hydraulic properties dihibrieos for flow and transport modelling based on the initial field-measured water content distributions and cihibridos set of scale-mean hydraulic parameters. Very good matches between the observed and simulated flow and transport behavior were obtained using the conditioning procedure, without model calibration.
The ALTS experiments djercicios designed to evaluate characterisation methods and their associated conceptual models for coupled matrix-fracture continua over a range of scales i.
Within these spatial scales, laboratory and field tests were conducted for estimating pneumatic, thermal, hydraulic, and transport property values for different conceptual models. The analyses included testing of current conceptual, mathematical and physical. Las CrucesNM 1: Mechanized and natural soil-to-air transfer of trifluralin and prometryn from a cotton field in Las CrucesNew Mexico.
Two pre-emergence herbicides trifluralin and prometryn were applied on a cotton field in Las CrucesNew Mexico, ejrecicios their atmospheric particle and gas-phase concentrations were measured during mechanized soil preparation and natural wind erosion sampling events before and after herbicide application. Air sampling was conducted using dihibrjdos mounted at various heights from the ground ejecicios at various locations on the field.
During mechanized soil management with a disk harrow, sampling occurred at two distances from the tractor “near-source”, 4 m downwind and “far-source”, m from the disking tractor.
Natural background no disking sampling events occurred during daytime and at night. Both herbicides were quantifiable for all postapplication sampling events, including background sampling that occurred 8, 38, and 40 days after herbicide application.
Averaging by event type, mean total prometryn concentrations were 2 night background to 8 near-source times higher than the corresponding trifluralin concentrations. Daytime natural background prometryn concentrations could be as high as those measured during disking, and background samples showed significant relationships to meteorological parameters air temperature, relative humidity, and dewpoint. Mechanical disturbance by tilling operations reduced the ability to predict airborne herbicide concentrations on the basis of meteorological.
Long-term monitoring of coastal ecosystems at Las CrucesChile: Defining baselines to build ecological literacy in a world of change Monitoreo de largo plazo en el ecosistema marino costero de Las CrucesChile: Full Text Available Marine coastal habitats are being increasingly impacted by human activities. In addition, there are dramatic climatic disruptions that could generate important and irreversible shifts in coastal ecosystems. Long-term monitoring plays a fundamental and irreplaceable role to establish general baselines from which we can better address current and future impacts and distinguish between natural and anthropogenic changes and fluctuations.

Here we highlight how over 25 years of monitoring the coastal marine ecosystem within the no-take marine protected area of Las Cruces has provided critical information to understand ecological baselines and build the necessary ecological literacy for marine management and conservation. We argue that this understanding can only be gained with simultaneous monitoring of reserves and human-impacted areas, and the development of complementary experimental studies that test alternative hypothesis about driving processes and mechanisms.
In this contribution we selected four examples to illustrate long-term temporal fluctuations at all trophic levels including taxa from algae to sea birds. From these examples we draw a few general lessons: The sharp differences in the pace at which depleted populations recover is at least partly related to differences in life history dispersal capabilities of the targeted species.
In addition we discuss. Criterion for American National Standard A This paper aims to provide the theoretical and practical elements of the use of interest rate swaps IRS and cross currency swaps CCS by Colombian companies, as hedging tools. Entre las variables estudiadas figuraron:
