چکیده

in vascular plants, the soil solution is transported from the roots to the leaves through smalldiameter vessels found in the xylem; this transport not only allows the nutrient uptake but also the accumulation of heavy metals in their shoots. by analogy to this phenomenon, the present study aimed at the evaluation of heavy metals transport (pb, cr, as, cd, zn, ni and al) in ph 4 and ph 8 solutions using a capillary siphon consisting of small pore diameter materials. determination of the metal concentration in the solutions was performed by means of inductively coupled plasma. the largest transport of metal ions is produced at ph 4, on ascending order, cr

Fate, transport, and interactions of heavy metals.

Mishandling of hazardous wastes, like their unauthorized disposal in abandoned dump yards or sites, in river beds, estuaries or in the sea, causes substantial damage to the environment and its resources and, given the persistence and toxicity of these pollutants, they can seriously damage human health and quality of life. The importance of controlling management, transport, and disposal of toxi...

Transport Properties of Heavy Electron Metals

Resistivity ( p ) and thermoelectric power (Q) experiments are described for two different ground states at zero pressure (P): a normal phase (CeA13) and a superconducting phase (UBel3). In CeA13, antiferromagnetism occurs clearly at P = 0 and may disappear rapidly under pressure. Magnetic field and pressure experiments in UBe13 show that antiferromagnetism and superconductivity may be antagonist.

Vulnerability of xylem vessels to cavitation in sugar maple. Scaling from individual vessels to whole branches.

The relation between xylem vessel age and vulnerability to cavitation of sugar maple (Acer saccharum Marsh.) was quantified by measuring the pressure required to force air across bordered pit membranes separating individual xylem vessels. We found that the bordered pit membranes of vessels located in current year xylem could withstand greater applied gas pressures (3.8 MPa) compared with border...
