Changes in Cs forms in soils during the 6 years after the accidental release of radioactive substances and availability of this radionuclide to plants at that time were dependent on the character of radioactive
with hundreds of astronauts spending months of their time in space. A recent shift toward pursuing territories farther afield, aiming at near-Earth asteroids, the Moon, and Mars combined with the anticipated availability of commercial flights to space in the near...

Non-target and suspect screening greatly increases the number of specific substances that can be evaluated, without a prior need for standards, and enables identification of previously unknown substances [5]. Advances in non-target screening also allow evaluation of decontamination processes (e.g., ...
The growth of bacteria in the form of individual colonies or from abundant to very abundant number of morphologically different colonies on Chocolate agar was observed. Initially biochemical identification and biotyping of 192 Gram-negative isolates (125 – from patients with sarcoidosis and 67 – ...
The cell wall is the first structure of a plant cell that is in contact with Cd; there- fore, it can change its composition and/or ratio of wall components accordingly. This paper investigates the changes in the anatomy and cell wall architecture of maize (Zea mays L.) roots grown for ...
Nevertheless, the brain and CSF exposure to many substances that are not subject to active transport do correlate with their protein binding 19,20. For some drugs, the ratio of bound to unbound (free) fractions may be sensitive to changes in the concentra- tion of the protein(s) they bind...
cash, hard cash, hard currency - money in the form of bills or coins; "there is a desperate shortage of hard cash" 6. change - a thing that is different; "he inspected several changes before selecting one" thing - an entity that is not named specifically; "I couldn't tell what the...
Physical changes include boiling water, dissolving sugar in coffee, melting ice, shredding paper, folding paper, or breaking an egg. Chemical changes include burning candles, rusting of metals, digesting foods, rotting of foods, and combusting substances. What are the three physical states of matte...
New growth in the form of callus was observed near the cambial zone. These callus cells initially had blue-staining cellulose-rich walls and were uniform in size and appearance. At later time points, crystals and lignin-rich red staining of cell walls were observed in the callus (Fig. ...
