9.3 INDUSTRIAL CHEMICALS AND NEUROTOXICITY Chemical substances and their applications in industry are common and the expo- sure of workers to them is known. Several chemical substances have been suspected as neurotoxicants, but the information on many of them[r]
The research objective of the dissertation is to research and apply enzyme technology to hydrolysis of plant glycoid compounds, creating higher activity products and developing green research in organic chemistry.
Over the last three decades, organic compounds uptake by roots, particularly pesticides/herbicides, has been widely studied [9-14]. Plant roots can take up organic contaminants via passive diffusive partitioning (i.e. apo- plastic) and/or active (i.e. symplastic) process,[r]
To finish this non-exhaustive description, we can briefly mentioned two device developments in the field of very low temperature measurements. A mini-goniometer for X-ray diffraction studies down to 4 K on a four-circle diffractometer equipped with a CCD area detector (Fertey et al., 2007)[r]
