Soil is an important reservoir for many persistent toxic substances (PTS), including polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalate esters (PAEs), and so on. These PTS have been received worldwide attention due to their high resistance to degradation, high bioaccumulation, and ...
During the past decades the understanding and prospects of enzyme-catalysed reactions have been massively widened and there are a number of implemented large-scale enzymatic processes mainly based in the use of commercial biocatalysts. As it might happen that the same process can be successfully carri...
In still another embodiment of the present invention, wherein the lutein stays at normal storage conditions, amenable for commercial applications. In the present invention, we have utilized n-butanol as the solvent, as it dissolves the Xanthophyll ester fully and fulfills the above criteria. The ...
However, not only the quantity but also the quality of vegetables is particularly important. Both quantity and quality can be affected by phthalic acid esters in the soils. Phthalic acid esters have been shown to inhibit the root length, shoot length, and biomass (fresh weight) of rapes (...
have become completely liquefied, the vessel is agitated in a bath maintained at 40" C. for 24 hours. The resulting milky dispersion is frozen to coagulate the polymer, which is then filtered and washed repeatedly with warm water 45 until substantially all residual dispersing agent has been ...
The hydrogels foams prepared with macroscopic gas cells will have an open celled structure similar to sponges except that the pore size will generally be an order of magnitude larger. Hydrogels may be used for many of same uses that have been described for polyoxaesters such as wound ...
Rosin is also slightly soluble in seawater (8.6×10−5 mol/L at pH=8.1) and antifouling paints containing rosin and similarly soluble salts thereof have existed for many years. Problems with the use of rosin in paints are also known. Paints based on a combination of wood rosin with ...
being the remaining 1-1.5% unsaponifiables, like in the case of extra virgin oil used for food consumption. The unsaponifiable fraction is constituted by a large number of micro-components which have the common characteristics of not forming...
This early discoloration has not been considered disadvantageous for many uses, and the efforts of most workers in this field have been directed towards minimizing the onset of the more serious heat deterioration which sets in during long heating, as in milling. However, because of this ...
Liquid galenical forms, which are satisfactory from a pharmaceutical and medical viewpoint and which contain, in particular, substantially water insoluble polypeptides, especially cyclopeptides such as the cyclosporins, have long been sought. Excipients used in available commercial forms possess poor ...
