in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.

abstract background: previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. objective: the present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers. materials and methods: 24 female rats, 170-200g weigh...

caffeic acid phenethyl ester(cape) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. a group of heterocyclic esters of caffeic acid was synthesized using mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catechol...

Results from any existing clustering algorithm that are used for segmentation are highly sensitive to features that limit their generalization. Shape is one important attribute of an object. The detection and separation of an object using fuzzy ring-shaped clustering (FKR) and elliptic ring-shaped clustering (FKE) already exists in the literature. Not all real objects however, are ring or ellip...
