The purpose of this study is to understand reference libraries of Isfahan University of Medical Sciences. The reference part of libraries was examined from 2008 to 2011. We found that the number of reference librarians should be increased. We found graduate students are the main patrons. We understand interaction with patrons is very important. This study will be helpful for specialist, librari...

One out of every six married couples experiences infertility at some point in their relationship. Most couples expect and desire to conceive children, and thus fulfill their “procreative duty.” However, this desire is interrupted by the pain of childlessness. Modern technology has responded through procedures such as artificial insemination or in vitro fertilization (IVF). If these technologies...

Every open continuous map f from a space X onto a paracompact C-space Y admits two disjoint closed sets F0, F1 ⊂ X , with f(F0) = Y = f(F1), provided all fibers of f are infinite and C∗-embedded in X . Applications are demonstrated for the existence of “disjoint” usco multiselections of set-valued l.s.c. mappings defined on paracompact C-spaces, and for special type of factorizations of open co...

During gastrulation of the nematode worm Caenorhabditis elegans, individual cells ingress into a solid ball of cells. Gastrulation in a basal nematode, in contrast, has now been found to occur by invagination into a blastocoel, revealing an unanticipated embryological affinity between nematodes and all other triploblastic metazoans.

I argue that is intuitive and useful to think about composition in light of the familiar functionalist distinction between role and occupant. This involves factoring the standard notion of parthood into two related notions: being a parthood slot and occupying a parthood slot. One thing is part of another just in case it fills one of that thing’s parthood slots. This move opens room to rethink m...
