A history of pest control measures in the anthropology collections, national museum of natural history, smithsonian institution
TL;DR: Since the mid-19th century, various pest eradication techniques have been employed on the anthropology collections at the National Museum of Natural History, Smithsonian Institution as mentioned in this paper, and these techniques are reviewed, and pesticide and fumigant use by early collectors and later collections management staff is documented.
Journal ArticleDOI
The characterization of pigments based on carbon
TL;DR: In this paper, the main features, molecular structures and physical and chemical properties of these carbon types, so far as they are relevant to pigment studies, are reviewed in outline and some better-known pigments based on carbon are summarized, with an indication of which form or forms of carbon each contains.

Zur katalytischen Bestimmung von Kupferspuren@@@On the catalytic determination of traces of copper: I. Bestimmung von Cu(II)-Spuren nach der Simultankomparationsmethode mit Hilfe der Eisen(III)-rhodanid-Thiosulfat-Reaktion@@@I. Determination of traces of Cu(II) by means of the simultaneous-comparison method using the iron(III) thiocyanate-thiosulphate reaction
TL;DR: In this paper, the influence of free HCl and of chlorides on the reaction rate and accuracy has been investigated, and several modifications of the procedure of Bognár [2] permitted to reduce the limit of detection to 1 ng Cu/ml without excessive increase of work.
