Marking Porcelain and Silica Crucibles, etc.

Unsuitability of porcelain crucibles for dry ashing of biological tissues for calcium analysis.

At temperatures required for complete release of calcium from beef liver by dry ashing, porcelain crucibles release significant amounts of calcium into the ash, which leads to erroneously high calcium values in the samples. Heated, empty porcelain crucibles do not show released calcium. Both fused silica and platinum crucibles fail to show any significant interaction with the sample. Samples dr...

Effect of Nano and Micro Silica on the pyroplastic deformation of Domestic porcelain tile

The term " pyroplasticity" refers to the deformation of the white ware that occurs during firing. In particular, this phenomenon is particularly important for tiles fired in roller kiln (especially thin and large dimensions) and the roughness created on the surface by vertical weight. In this study, 1, 3 and 5% of nanosilica and microsilica were replaced in porcelain tile batch. The effect of n...

Introduction etc

Bilateral and multilateral development cooperation agencies are to an increasing extent promoting and adopting a sector-wide approach (SWAp) in their development cooperation. The Swedish International Development Cooperation Agency (Sida), for example, joined their first sector-wide approach cooperation in the late 90s, and today they are involved in SWAps in countries in Africa, Asia and Latin...

Stress granules as crucibles of ALS pathogenesis

Amyotrophic lateral sclerosis (ALS) is a fatal human neurodegenerative disease affecting primarily motor neurons. Two RNA-binding proteins, TDP-43 and FUS, aggregate in the degenerating motor neurons of ALS patients, and mutations in the genes encoding these proteins cause some forms of ALS. TDP-43 and FUS and several related RNA-binding proteins harbor aggregation-promoting prion-like domains ...
