reproductive risk of incomplete fertilization (Mortensen, 1938). Given evidence of at least occasional sperm limitation in marine environments (Levitan and Petersen, 1995; Yund, 2000), recent work has examined whether this risk is reduced by particular features of adults or gametes that could improve chances of sperm–egg encounter (Denny et al., 1992; Levitan et al., 1992; Petersen et al., 1992...

Despite over a decade of research into content-based image retrieval (CBIR), the task of finding a desired image in a large collection remains problematic. Even in application areas where there is a clear need for effective image retrieval, such as medical diagnosis and trademark registration, current technology fails to meet user needs. Much existing research has concentrated on retrieval tech...

The vermiform appendix, a small structure without any known function in human being has been regarded as a vestigial remnant of a more developed distal caecum in man's herbivorous ancestors. A detailed study of the morphological and histological changes in the appendix and the caecum of different mammals with varying dietary habits revealed a distinctly well-defined vermiform appendix in rabbit...

Endometrial dysfunction is a possible cause of infertility in women with endometriosis, which could explain the high rates of implantation failure and miscarriages in these women. Delay in endometrial maturation and intrauterine biochemical abnor...

An element of a ring $R$ is called clear if it sum unit-regular and unit. associative each its elements clear.In this paper we defined rings extended many results to wider class. Finally, proved that commutative Bezout domain an elementary divisor only every full $2\times 2$ matrix over nontrivially clear.
