A putative protease gene (aprE) from the thermophilic bacterium Coprothermobacter proteolyticus was cloned and expressed in Bacillus subtilis. The enzyme was determined to be a serine protease based on inhibition by PMSF. Biochemical characterization demonstrated that the enzyme had optimal activity under alkaline conditions (pH 8-10). In addition, the enzyme had an elevated optimum temperature...

Two of the most recent and powerful multi-property-preserving (MPP) hash domain extension transforms are the Ramdom-Oracle-XOR (ROX) transform and the Enveloped Shoup (ESh) transform. The former was proposed by Andreeva et al. at ASIACRYPT 2007 and the latter was proposed by Bellare and Ristenpart at ICALP 2007. In the existing literature, ten notions of security for hash functions have been co...

due to the lack of information on most stations and economic constraints for collecting observed data. identification of a suitable hydrological model can help in the management of water resources. the ihacres model doesn't require complex data for input, so this model is superior to other models. in this research the efficiency of ihacres model for simulation of daily flow for polrood and...

Bacillus is remarkable for its extracellular enzyme production (Priest, 1977). When Bacillus cells exhaust the nutrients of the environment and enter into the stationary phase, neutral and alkaline proteases encoded by nprE and aprE respectively are produced and secreted to the outside environment (Chaloupka and Kreckova, 1966; Din et al., 1969). The mechanism of aprE expression has been extens...

Recently, Yamamoto presented a new method for the conversion from regular expressions (REs) to non-deterministic finite automata (NFA) based on the Thompson ε-NFA (AT). The AT automaton has two quotients discussed: the suffix automaton Asuf and the prefix automaton, Apre. Eliminating ε-transitions in AT, the Glushkov automaton (Apos) is obtained. Thus, it is easy to see that Asuf and the partia...

 Annalisa Andreoni, coordinatrice del Gruppo di Studi delle donne nella letteratura italiana dell’Associazione degli Italianisti, apre i lavori Convegno Margherita Costa, poetessa virtuosa (L’Aquila, 12 aprile 2021).

General equations and numerical tables are developed for quanti®cation of the probabilities of sequentially dependent repeatable human errors. Such errors are typically associated with testing, maintenance or calibration (called apre-accidento or apre-initiatoro tasks) of redundant safety systems. Guidance is presented for incorporating dependent events in large system fault tree analysis using...
