Characterization of the Structure of Saudi Crude Asphaltenes by X-ray Diffraction [PDF]
, 1997 Structural characterization studies have been carried out on four commercial Saudi Arabian crude oils. The aromaticity and crystallite parameters of the asphaltenes were studied by X-ray diffraction methods and compared to the average structural ...

Structural Characterization of Nitrimyoglobin
Journal of Biological Chemistry, 1989 Nitrimyoglobin was formed in greater than 94% yield by a simple reaction between excess nitrite and horse heart metmyoglobin at pH 5.5. This dark green pigment was shown by 1H NMR spectroscopy to be a single, pure product with a well defined tertiary structure that is highly similar to the starting myoglobin.

Community Structure Characterization [PDF]
, 2017 This entry discusses the problem of describing some communities identified in a complex network of interest, in a way allowing to interpret them. We suppose the community structure has already been detected through one of the many methods proposed in the literature. The question is then to know how to extract valuable information from this first result,

A characterization of the finite Veronesean by intersection properties [PDF]
, 2012 A combinatorial characterization of the Veronese variety of all quadrics in PG(n, q) by means of its intersection properties with respect to subspaces is obtained. The result relies on a similar combinatorial result on the Veronesean of all conics in the

A Structurally Characterized Fluoroalkyne
Angewandte Chemie, 2017 AbstractThe facile synthesis of a stable and isolable compound with a fluoroalkynyl group, M−C≡CF, is reported. Reaction of [Ru(C≡CH)(η5‐C5Me5)(dppe)] with an electrophilic fluorinating agent (NFSI) results in the formation of the fluorovinylidene complex [Ru(=C=CHF)(η5‐C5Me5)(dppe)][N(SO2Ph)2].

Structure characterization of the 26S proteasome [PDF]
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2011 In all eukaryotic cells, 26S proteasome plays an essential role in the process of ATP-dependent protein degradation. In this review, we focus on structure characterization of the 26S proteasome. Although the progress towards a high-resolution structure of the 26S proteasome has been slow, the recently solved structures of various proteasomal ...
