In this paper, we studied fuzzy linear fractional programming Collections (FLFP) problems with trapezoidal fuzzy numbers where the objective functions are fuzzy numbers and the constraints are real numbers.In this study, in order to obtain the fuzzy optimal solution with unrestricted variables and parameters, a new efficient method for FLFP problem

Avian influenza causes substantial economic loss in the poultry industry and potentially threatens human health.Over recent years, the highly pathogenic avian influenza A/H5N1 virus has led to devastating losses in poultry flocks and wild birds.At the same time, the number of mammalian species identified to be infected with A/H5N1 is increasing, wi
Mycoplasma genitalium is a sexually transmitted bacterial pathogen that infects men and women.Antigenic variation of MgpB and MgpC, the immunodominant adherence proteins of M.genitalium, is thought to contribute to immune evasion and chronic infection.We investigated the evolution of mgpB and mgpC sequences in men with non-gonococcal urethritis per
