or partially covalent, bond of the protein under study (Cohen, 1970), hence also the more general term 'covalent modification' (Brocklehurst, 1982). Protein modification studies have so far aimed at: (a) the determination of the kind and number of reactive groups of the protein molecule under study, (b) the development of site-specific protein modifying agents, and (c) the elucidation of enzyme...

While Africa’s economies too are now growing, in many African countries, people are just now returning to the levels of per capita income they enjoyed more than a half century ago. 1 Th e current poverty and the widespread economic decline foll...

Self-organized networking is foreseen as an important component in the Internet’s near-future architecture. An essential challenge concerning the integration of this new component is the accomplishment of scalable and efficient ad hoc routing. This report proposes a new solution in this space, DHT-OLSR, based on OLSR enhanced with dynamic clustering and distributed hash table (DHT) routing. We ...

We prove that, in the category of groups, the composition of a cellularization and a localization functor need not be idempotent. This provides a negative answer to a question of Emmanuel Dror Farjoun.

In the redetermined structure [Koo (1965 ▶). Bull. Chem. Soc. Jpn, 38, 286] of the title compound, C(6)H(9)N(2) (+)·Cl(-), the H atoms have been located and the hydrogen-bonding scheme established. A series of N-H⋯Cl and N-H⋯N hydrogen bonds leads to a layered network parallel to the (010) plane.
