The standard model for the dynamics of a fragmented density-dependent population is built from several local logistic models coupled by migrations. First introduced in the 1970s and used in innumerable articles, this standard model applied to a two-patch situation has never been completely analysed. Here, we complete this analysis and we delineate the conditions under which fragmentation associ...

Facilitating factors Challenging factors A “burning platform” following two Fear of reprisal very tragic adverse events Strong leadership support Strong program and professional autonomy Good quality improvement culture Inconsistent follow-up of ideas and infrastructure and initiatives Well established morbidity and Fragmented risk-reporting mortality review processes systems Clinical informati...

In 2 crisp introductory chapters, editor H. Tristram Engelhardt Jr assembles evidence to support this claim. Culture wars have fragmented bioethics into rival camps. Competing groups, each adhering to a different worldview, endlessly dispute the major issues of human life: sexuality, reproduction, allocation of resources, the significance of suffering and dying. It is impossible to resolve cont...

Case studies are an essential feature of process modelling research. This work introduces a possible structure to assist in assembling and reporting the fragmented ndings of such experiences

The occurrence of DNA fragmentation in lymphocytes obtained from alloxan-induced diabetic rats and diabetic patients was investigated. A high proportion of apoptotic lymphocytes in diabetic states may explain the impaired immune function in poorly controlled diabetic patients. Rat mesenteric lymph node lymphocytes were analysed for DNA fragmentation by using flow cytometry and agarose gel, and ...

Background The high effectiveness of vitrification, as a cryopreservation protocol, for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. This study aimed to assessment of follicular growth, ultrastructure, and apoptosis incidence in human ovarian tissue following vitrification/warming and after culture in the presence of LIF. MaterialsAndMethods Ovarian cort...

In this paper, we introduce a computational model for the simulation of hypervelocity impact (HVI) phenomena which is based on the Discrete Element Method (DEM). Our paper constitutes the first application of DEM to the modeling and simulating of impact events for velocities beyond 5 kms-1. We present here the results of a systematic numerical study on HVI of solids. For modeling the solids, we...

sam shepard is one of the foremost living american playwrights. he has always been concerned with the problem of identity, specifically the fragmented identity of man living in the postmodern era. such characterization is evident in his plays: true west, fool for love, and a lie of the mind. thus, the present article is to demonstrate the fragmented identity of lee and austin, eddie and may, an...
