Abstract: Let R be an open equivalence relation on a topological space E. We define on E a new equivalence relation ̃︀ R by x̃︀ Ry if the closure of the R-trajectory of x is equal to the closure of the R-trajectory of y. The quotient space E/̃︀ R is called the trajectory class space. In this paper, we show that the space E/̃︀ R is a simple model of the quotient space E/R. This model can provide a f...

INTRODUCTION It has previously been reported that patients aged over 65 years account for 15% of Accident and Emergency (A&E) attendances. Despite this, there have been few studies looking at older people's use of A&E. This study describes the A&E attendance patterns of older people, defined as those aged 65 years and over, using data from an NHS region over a number of years. Their attendances...

Background: Lung carcinoma is a multiple type cancer comprising of small cell and non-small cell carcinomas (NSCLC). For therapeutic and diagnostic purposes, serum monoclonal antibodies have been produced against lung cancer. Objective: To charac-terize a murine monoclonal antibody (ME3D11) reactive with human NSCLC. Methods: A murine monoclonal antibody (ME3D11) reactive with human NSCLC was s...
