In the numerical simulation of blood ow problems it might happen that the only available physical boundary conditions prescribe the ow rate incoming=outgoing the vascular district at hand. In order to have a well-posed Navier–Stokes (NS) problem, these conditions need to be completed. In the bioengineering community, this problem is usually faced by choosing a priori a velocity pro le on the in...

We develop a simple dynamic model of a worker’s transitions between employment and non-employment. Our model implies that a worker finds a job at an optimal stopping time, when a Brownian motion with drift hits a barrier. The model has structural duration dependence in the job finding rate, in the sense that the hazard rate of finding a job changes during a non-employment spell for a given work...

The aim of this paper is to understand recent observations of fertility, female employment, and participation rates in O.E.C.D. countries. These observations indicate that fertility rates are positively correlated with female employment ratios and participation rates across O.E.C.D. countries during the period 1985-1996. Moreover, the time series observations show that fertility rates are procy...

Gene synthesis is hampered by two obstacles: improper assembly of oligonucleotides; oligonucleotide defects incurred during chemical synthesis. To overcome the first problem, we describe the employment of a Computationally Optimised DNA Assembly (CODA) algorithm that uses the degeneracy of the genetic code to design overlapping oligonucleotides with thermodynamic properties for self-assembly in...

This study describes a PCR-based approach for the production of a rationally attenuated mutant of Yersinia pestis. Degenerate primers were used to amplify a fragment encoding 91.45% of the aroA gene of Y. pestis MP6 which was cloned into pUC18. The remainder of the gene was isolated by inverse PCR. The gene was sequenced and a restriction map was generated. The Y. pestis aroA gene had 75.9% ide...

BACKGROUND The recent rehabilitation literature does not include a thorough assessment of the employment concerns of people with MS. OBJECTIVE This article presents descriptive findings from a national survey of the employment concerns of Americans with multiple sclerosis (MS; N = 1,924), representing nine chapters of the National Multiple Sclerosis Society. METHODS Respondents were asked t...

Increased mortality is often reported among workers in short term employment. This may indicate either a health-related selection process or the presence of different lifestyle or social conditions among short term workers. The authors studied these two aspects of short term employment among 16,404 Danish workers in the reinforced plastics industry who were hired between 1978 and 1985 and were ...

UNLABELLED In this secondary analysis of data from a randomized controlled trial comparing supported employment with treatment as usual, we sought to evaluate the study incident rate of legal involvement and subsequent effects of legal involvement on employment among 157 job-seeking Veterans with spinal cord injury. The supported employment vocational rehabilitation program, called the Spinal C...
