Numerical Modeling for the Solute Uptake from Groundwater by Plants-Plant Uptake Package
… in groundwater to simulate sorption and plant uptake is used. The mathematical equation is solved using finite difference technique to solve for the concentration at any grid cell with respect to time. The new package is integrated into SEAM3D to create a new SEAM3D Plant Uptake Package, or …

River oxygen uptake by benthic microorganisms
The factors influencing benthic microbial uptake of river dissolved oxygen (DO) and dissolved organic matter (DOM) were investigated in 4 New Zealand rivers receiving organic waste discharges from dairy factories and a pulp and paper company. A chamber system for in situ use was developed and …

Ambiguity Aversion: Adoption, Uptake, and Trends
<p>What is ambiguity aversion and what is its role as a determinant of technology adoption? This study develops and implements a novel ambiguity preference instrument in the context of an ongoing RCT pilot program in southwest Uganda promoting adoption of an improved variety of sweet potato. No …

Zinc Uptake in Loblolly Pine Seedlings
… were early spring, late spring, and summer. Zinc uptake was the greatest in early spring. Zinc nitrate fertilizer and remaining soil zinc at treatments end had no effect on mycorrhizae, height, or diameter growth. Linear and multiple regressions were derived using residual soil zinc and treatment …

Oral uptake and distribution of microspheres
… with large volumes of hypotonic liquid, and that uptake was very rapid. Test particles were detected in blood, only a few minutes after dosing. To improve quantification, GPC technology was adopted. 0.22 m latex particles were found to accumulate in greatest numbers within the Mononuclear …

Toxicology of nanoparticles after cellular uptake
Nanoscience is a multi-disciplinary field with the potential to both create new applications and understand existent systems, but its materials may be sources of toxicological concern. Understanding their toxic potential becomes essential to prevent any occupational, environmental, and consumer …

Uptake of kepone by aquatic macrophytes
… after the initial three day exposure. Kepone uptake by the roots of American bulrush and smooth cordgrass appeared to continue for a seven day period. Translocation to the aerial portions of the plants was slow, with significant quantities reaching the shoot after seven days. Additional …

Nitrogen uptake of saprotrophic basidiomycetes and bacteria
Saprotrophe Basidiomyceten können unter aeroben Bedingungen Holz abbauen und wirtschaftliche Schäden verursachen. Die Stickstoffverfügbarkeit ist für diesen Abbau entscheidend, und diazotrophe Bakterien können durch Fixierung von atmosphärischem N2 Stickstoff auf Holz anreichern. Der gemeinsame …

Vanadium uptake and transport in higher plants
The uptake and transport of vanadium in several higher plant species has been examined. Studies utilizing excised Hordeum roots have revealed the uptake patterns of two different ionic species of vanadium (V02+ and V03) to be similar. Both ionic forms exhibited a large extracellular component in …

Oxygen Uptake Kinetics in Severe Intensity Exercise
… study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in ~3 to …

Maximum oxygen uptake predicted from submaximal tests
… workload, the ARN also uses submaximal oxygen uptake as a parameter; The purpose of this study was to determine which of the 3 types of exercises used with the Astrand-Ryhming nomogram predicted max VO2 most accurately; Thirty subject's between the ages of 18 and 35 performed maximally on a …

Switchgrass tolerance to cadmium: uptake and translocation
Recent efforts have been initiated to develop switchgrass (Panicum virgatum L.) as a bioenergy crop. Switchgrass requires input of nitrogen (N) to be productive. Alternatives to inorganic fertilizers are needed to reduce input costs and maintain a positive energy balance. Municipal sludge may be an …

Manipulating PLGA nanoparticle cellular uptake and trafficking
… PLGA NPs through manipulating their cellular uptake and intracellular trafficking to a specific compartment inside the cell by modulating physicochemical properties i.e. size. Different sizes of Rhodamine-B conjugated PLGA NPs were synthesized and optimized to achieve the required sizes (< …

Double-stranded RNA uptake in Caenorhabditis elegans
dsRNA uptake from the environment is a common phenomenon in many invertebrates and can be harnessed for acquiring pest control. In the nematode Caenorhabditis elegans, a transmembrane protein named systemic RNAi deficient-2 (sid-2) is required for dsRNA uptake from the environment through the …
