A theorem due to L. J. Gleser stating that a gamma distribution with shape parameter no greater than one is a mixed exponential distribution is extended to generalized gamma distributions introduced by E. W. Stacy as a special family of lifetime distributions containing both gamma distributions, exponential power and Weibull distributions. It is shown that the mixing distribution is a scale mix...

Paris, Gare de Lyon, 27 June, 1988, 18:47. A crowded suburban train is ready for departure when, suddenly, another train arrives in front of it. There is a crash with 56 dead and hundreds injured. Obviously the killer train had no brakes. Why? The French government immediately set up a commission to analyse the disaster. This commission published its analysis in a report in September 1988 [1]. ...

In this letter we compute the correction to the entropy of Schwarzschild black hole due to the vacuum polarization effect of massive scalar field. The Schwarzschild black hole is supposed to be confined in spherical shell. The scalar field obeying mixed boundary condition on the spherical shell.

Background: Pandemic of the Covid-19 needs serious attention. This is because rate spread this virus very fast, so that an attitude and understanding obedience to health protocol needed stop Covid-19. study aims find relationship between community in carrying out protocols readiness adapt with Covid-19.Methods: used quantitative research a cross sectional, which was conducted one Rukun Warga Pa...

Background: Although past research highlights the impact of self-efficacy on university students’ learning motivation, examining potential links with specific types conformity is limited. The current study examined associations between Chinese perceived and across different motivation.Methods: A total 339 students were surveyed using General Self-Efficacy Scale Learning Conformity Scale. Multip...
