The cross sections for the reactions of the strange production p + p → p + Λ + K+ and p + p → p + Σ0 + K+ near thresholds of the final states pΛK+ and pΣ0K+ are calculated in the effective Lagrangian approach. Our approach is based on the dominant contribution of the one–pion exchange and strong interaction of the colliding protons in the initial state. The theoretical values of the cross secti...

The relationship between enzyme activity and destruction of bacteria by disinfectants has been the subject of numerous investigations in recent years. In 1927, Quastel and Wooldridge studied the effect of chemical and physical agents on various dehydrogenases of Escherichia coli. In several experiments, the treated organisms were subcultured to compare the viability of the organisms with their ...

In this paper we propose an algorithm for computing large primes p and q such that q divides p + p + p + p + p + p + 1 or p − p + p − p + p − p + 1. Such primes are the key parameters for the cryptosystem based on the 7th order characteristic sequences.

in this paper, we introduce $p$-semilinear transformations for linear algebras over a field ${bf f}$ of positive characteristic $p$, discuss initially the elementary properties of $p$-semilinear transformations, make use of it to give some characterizations of linear algebras over a field ${bf f}$ of positive characteristic $p$. moreover, we find a one-to-one correspondence between $p$-semiline...
