we will examine a family of numerical semigroups embedding dimension three, such that S_u=< 8,8u+2,8u+9> where u >=1, is integer . Also, give some relationsbetween these and their Arf closure.

Background: Gas stations are one of the most well-known risky potentials in cities. Attitude and culture are underlying reasons for unsafe behaviors, which can lead to accidents. This study aimed to evaluate safety culture among workers of gas stations in the city of Zanjan. Methods: In this descriptive analytical study, a valid safety culture questionnaire consisting of five dimensions was us...

Psychologists interested in culture have focused primarily on East-West differences in individualism-collectivism, or independent-interdependent self-construal. As important as this dimension is, there are many other forms of culture with many dimensions of cultural variability. Selecting from among the many understudied cultures in psychology, the author considers three kinds of cultures: reli...

Abstract We study the Hamiltonian for a system of three identical bosons in dimension interacting via zero-range forces. In order to avoid fall center phenomenon emerging standard Ter-Martirosyan–Skornyakov (TMS) Hamiltonian, known as Thomas effect, we develop detail suggestion given seminal paper Minlos and Faddeev 1962 construct regularized version TMS which is self-adjoint bounded from below...
