Abstract Introduction The increase of human space missions in microgravity conditions has led the scientific community to investigate potential effects on astronauts' bodies. There is a high incidence cardiovascular complications, with cardiac arrest being among most difficult manage. On earth, guidelines regarding cardiopulmonary resuscitation are constantly updated; however, microgravity, lit...

A total of 200 faecal samples, received between January and December 2004 from patients with acute diarrhoea, were of patients with acute brucellosis (69 families) who were referred to Boo-Ali Hospital (Southeast Iran) were enrolled in this study and serologically screened for brucellosis using the standard agglutination test (SAT). Titer of 160 or more was considered positive and diagnostic Ti...

Conformal Killing vectors (CKVs) preserve the spacetime metric up to a factor. Homothetic vectors and Killing vectors are special cases of CKVs. Classification of some classes of spacetimes on the basis of CKVs give interesting results showing how homothetic and Killing vectors which form subsets of the set of CKVs can be recovered as a result of the above classification. ∗On leave from: Centre...

The significant increase in the complexity and autonomy of the hardware systems renders the verification of the functional safety of each individual component as well as of the entire system a complex task and underlines the need for integrated, model based tools that would assist this process. In this paper the authors present such a tool, coupled with an approach to functional safety analysis...

The purpose of this study was to prospectively compare parameters that might predict successful translaryngeal extubation and tracheostomy tube decannulation. Irrespective of ventilatory function, 62 extubation/decannulation attempts were made on 49 consecutive patients with primarily neuromuscular ventilatory insufficiency who satisfied criteria. Thirty-four patients required 24-h ventilatory ...

In an attempt to depict the nutritional status of Kurdish refugee children under five years of age. a rapid survey was conducted on 900 children in 9 camps of Kurdistan and Bakhtaran province in May 1991. The study included anthropometric measurements on all. clinical examination of 731, and biochemical tests for anemia and protein energy malnutrition (PEM) on 160 subjects. The results sho...

Throughout this paper, k denotes a field of characteristic 0. We write E8 for the split simple algebraic group with Killing-Cartan type E8. The Galois cohomology set H (k, E8) classifies simple algebraic groups of type E8 over k. One of the goals of the theory of algebraic groups over arbitrary fields is to understand the groups of type E8, equivalently, understand the set H(k, E8). The main to...

Human umbilical vein endothelial cells attach and spread on laminin-coated substrates. Affinity chromatography was used to identify the attachment receptor. Fractionation of extracts from surface-iodinated endothelial cells on human laminin-Sepharose yielded a heterodimeric complex, the subunits of which migrated with molecular sizes corresponding to 160/120 kD and 160/140 kD under nonreducing ...
