Background Although the depth of the counting chamber is an important factor influencing sperm counting, no research has yet been reported on the measurement and comparison of the depth of the chamber. We measured the exact depths of six kinds of sperm counting chambers and evaluated their accuracy. MaterialsAndMethods In this prospective study, the depths of six kinds of sperm counting chamber...

the field of comparative analysis on persian and arabic grammars and in contrast to number and counted nouns discourses in both languages it is revealed that there is a numerical composition in either double-bases (simple) or triple- bases (it has counting conjunction or counting unit in persian and quantifier in arabic). this categorization may itself open some other new classes and lead to pu...

This paper presents three new systematic approaches for computing coefficient matrices of the Heffron-Phillips multi-machine model (K1, …, K6). The amount of computations needed for conventional and three new approaches are compared by counting number of multiplications and divisions. The advantages of new approaches are: (1) their computation burdens are less than 73 percent of that of convent...

The Li–Wan sieve [11] is extended to multisets when the underlying set symmetric. main ingredient of proof Möbius inversion formula on poset partitions {1,2,…,k} ordered by refinement. As illustrative applications, we investigate problems over finite fields and zero-sum additive group Z/nZ.
