Montana 1911: A Professor and His Wife Among the Blackfeet: Wilhelmina Maria Uhlenbeck-Melchior's Diary and C.C. Uhlenbeck's Original Blackfoot Texts and a New Series of Blackfoot Texts

In the summertime of 1911, Dutch anthropologist and linguist C. C. Uhlenbeck traveled to Montana to behavior fieldwork one of the southern Piegan Indians. Accompanying him in the course of his three-month remain was once his spouse, Wilhelmina, who stored a diary in their stories one of the Blackfeet. This diary is reproduced right here in complete, translated for the 1st time from Dutch into English via Mary Eggermont-Molenaar.

The powder results from the conversion of -C2 S to -C2 S at around 675 C. Since -C2 S and -C2 S have different crystal structure and density, the conversion of -C2 S to -C2 S is accompanied by an increase in volume of nearly 10% and results in the shattering of the crystals into dust. In the water-spray cooling process, molten steel slag is poured into a pit and cooled in air. Water is sprayed onto the surface of the steel slag after the molten steel slag is solidified so the solidified steel slag will break into pieces itself due to the temperature differences, which will make the slag handling and metal recovery much easier.

Its crystals are frequently tabular pyramids of the orthorhombic system. It has a melting point of 882 C and decomposition temperature of 1100 C. 0 for 1% solution. 2 Resources of sodium sulphate Sodium sulphate comes from either natural resources or from various manufacturing processes. Natural sodium sulphate is mainly from naturally Alkaline activators 27 occurring sodium-sulphate-bearing brines or crystalline evaporite deposits found in alkaline lakes in areas with dry climates and restricted drainage, from sub-surface deposits and brines (Kostick 1993b).

However, more structural information with respect to the anionic structure of silicate solutions has become available only with the development and refinement of methods such as 29 Si-NMR (nuclear magnetic resonance) spectroscopy, paper chromatography, TMS, infrared spectroscopy (IR) and Raman spectroscopy, over the last twenty years. Despite these important advances in analytical techniques, the relationships between structure, properties and silicate species are still not completely understood, because the silicate species in solutions are so variable.
