In patients with out-of-hospital cardiac arrest, the effectiveness of drugs such as epinephrine is highly time-dependent. An intraosseous route drug administration may enable more rapid than an intravenous route; however, its effect on clinical outcomes uncertain.
Mangrove forests are a biodiverse ecosystem known for wide variety of crucial ecological services, including carbon sequestration, coastal erosion control, and prevention saltwater intrusion. Given the importance mangrove forests, comprehensive up-to-date extent mapping at broad geographic scales is needed to define forest changes, assess their implications, support restoration activities decision making. The main objective this study evaluate classifications derived from combination...
Abstract The purposes of this study were to determine how geomorphology and stratigraphy influence soil water O 2 regimes, regimes are reflected in color patterns, patterns can be used predict behavior suitability for various uses. We measured table depths, soil‐water levels, saturated hydraulic conductivity ( K sat ), described soils formed silty loess loam glacial till two forested toposequences. In both sequences, Aqualfs Aquolls on the swells swales, respectively, plain summit, Udalfs...
ABSTRACT Plant uptake of radionuclides is one many vectors for introduction contaminants into the human food chain. Thus, it critical to understand soil–plant relationships that control nuclide bioavailability. Our objectives in this study were (i) determine extent U and Th cycling by blueberry ( Vaccinium pallidum Aiton) native habitat (ii) identify soil properties processes contribute most bioavailability system. We collected composite samples plant leaves stems, from surface (AE) horizons...
Abstract Naturally occurring radionuclides in soil profiles can provide a useful pedological tool, if their distribution be calibrated to pedogenesis. As first step toward such calibration, this study presents radio‐pedogenic index that compares differences between sola and parent material with respect distributions equilibrium relationships of 214 Pb 228 Ac activity. The ratios Ac/ were used indicate concurrent secular within the 232 Th 238 U decay series. Among 12 Typic Haplorthod pedons...
Interactions between dissolved organic C (DOC) and mineral soils were examined in a laboratory column study. Specific emphasis was given to comparisons of soil solution measurements (OC) retention four parent materials. Soil columns leached with one three concentrations forest floor (FF) leachate or distilled water every third day for 1 yr. The concentration DOC analyzed before after percolation through assess net release DOC. Changes chemical properties (pH, loss‐on‐ignition [LOI],...
Plant uptake of radionuclides into the human food chain is one many vectors used for calculating exposure rates and performing risk assessment. This study provides a pedogenic assessment soil–plant relationships in terms their to nuclide bioavailability. The objectives this were (i) identify associations U Th with fractions soil properties, (ii) evaluate bioavailability processes. We collected composite samples leaves, stems, AE Bs horizons from 10 plots containing Spodosol naturally high...
The PARAMEDIC-3 trial evaluates the clinical and cost-effectiveness of an intraosseous first strategy, compared with intravenous for drug administration in adults who have sustained out-of-hospital cardiac arrest.
Current growth rates of human population have increased the areal extent anthropogenic soils. One most important aspects this disturbance is creation new soil surfaces and landscapes, which are not currently characterized, classified, or mapped in sufficient detail to develop adequate interpretations for subsequent uses. We characterized 20 pedons four abandoned sand gravel pits order determine physical, chemical, morphological properties were useful development map units interpretations....
Abstract Spodosols are notably difficult to classify in terms of moisture regime, presumably because redox colors masked by spodic colors, or perhaps the absence structure sandy is a hindrance detection features. Some views Spodosol pedons as series compartments raise possibility that some portions pedon simply more responsive than others saturation parameters. This study attempts determine whether compartmentalization within results differentiation soil response and water table fluctuation....

Increased tourism in Belize over the last decade and growth of local population have led to coastal development infrastructure expansion. Land use alteration anthropogenic activity may change sediment nutrient loads systems, which can negatively affect ecosystems via mechanisms such as reducing photosynthetically active radiation fields, smothering sessile habitats, stimulating eutrophication events. Accurate monitoring prediction water quality parameters Total Suspended Sediments (TSS), are...
Models of podzolization for northern New England soils are largely limited to organo-chelate models, which adequate explain ortstein development but inadequate other types indurated horizons, such as those observed in the Success series (sandy-skeletal, mixed, frigid, Typic Haplorthod). In order better understand genesis these soils, have light-colored, horizons below oxalate-extractable Si, Al, Fe, total C, pH, and micromorphological properties were determined six pedons. Profile...
Soil quality is defined as the capacity of soil to function within a specific kind ecosystem in manner that sustains plant and animal productivity, maintains or enhances water air quality, supports human health habitation (Karlen et al. 1992). therefore not controlled determined by any single process but variably, depending on land use, type, location, interactions (Kennedy Papendick 1995). In recent years, growing interest has stemmed from need develop more sustainable management (e.g.,...
Abstract As soil scientists develop recommendations for the classification and interpretation of anthropogenic soils, many altered soils will need to be described classified, probably at a variety taxonomic levels. One agent alteration may application liquid wastes extended periods time, with potential creating aquic conditions in those soils. Although such could logically termed anthraquic , no provision exists recognizing nonagricultural these morphological characteristics reversed if...
Elevated levels of naturally occurring radionuclides in bedrock many areas North America pose important issues for public health. Although soil surveys provide a great deal information on properties and interpretations, most do not include radioactivity levels. The objectives this study were to: (i) develop field protocol determining relative soils derived from parent materials with high radionuclides; (ii) determine whether those could be differentiated at the series level; (iii) ascertain...
Abstract Within landscape units of interest to soil surveyors and soilgenesis researchers, economic physical constraints generally prohibit collection sufficient data develop adequate predictive models spatial variability. Conceptual are more legitimate at these scales, modal concepts based on central‐tendency values can be used effectively models. Our objectives were obtain for genetically important properties two similar New Hampshire soils, use quantify each soil, relate depositional...
