Preparation of new classes of aliphatic, allylic, and benzylic zinc and copper reagents by the insertion of zinc dust into organic halides, phosphates, and sulfonates. J. Org. Chem. 57, 5425–5431 (1992). Article CAS Google Scholar Bose, A. K., Gupta, K. & Manhas, M. S. β-...
To date, microorganisms are only measured at composting plants, thus raising the issue of extrapolation to environmental situations. Lung damage and allergies may occur because of organic dust, Gram negative bacteria, actinomycetes and fungi. Further research is needed on the risk related to ...
The record of mineral atmospheric input illustrates the notable impact of human activities on soil erosion and dust entrainment in the Central Alps. Furthermore, links between Little Ice Age cold phases and reduced human impact and mining are established. Our high-resolution peat-geochemistry data ...
The world’s mega trends of land-use and landscape development are discussed, which are urbanization and land-use intensification, particularly considering their negative consequences for the ecological as well as the socio-economic environment. Trade-of
Sven Oden (1919) postulated that HS are the light to dark-brown substances of unknown materials, which are formed in nature by the decomposition of organic mat- ter through the actions of microorganisms or in a labora- tory by oxidizing chemical reagents. Alternatively, it was suggested that ...

Conversion of the benzofurans to the compounds of formula (I) may be affected by oxomolysis and subsequent treatment with dimethylsulphide or with zinc dust in acetic acid, or by chronic acid hydrolysis. Where oxonolysis is effected of a benzofuran having Y5 as alkyl, aryl or aralkyl, ...
aqueous solution containing one gram equivalent of sodium nitrite, a 5 percent w/w solution in glacial acetic acid containing one gram equivalent of benzyl propionylacetate, a suspension in glacial acetic acid of one gram equivalent of ethyl acetoacetate and four gram equivalents of zinc dust. The...
(0.2 mol) of zinc dust were added a little at a time over a period of 1 h. After the addition had ended, the solution was stirred for another 4 h, the remaining Zn was filtered off and the solution was admixed with 200 ml of ice water. The product was extracted with diethyl ...
This disclosure provides a method of inducing production of vascular endothelial growth factor by a cell. The method includes contacting the cell with a CpG oligonucleotide, thereby inducing the production of vascular endothelial growth factor by the cell. The disclosure further provides a method induci...
