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...

The current study describes the extracellular hydrolytic activities of halophilic bacteria isolated from subterranean rock salt. The estimated number of grown colonies was approximately 3000 per gram of a rock salt on the surface of the medium MH containing 10% NaCl. The investigated strains, randomly selected from the colonies observed on the plate, showed at least one of the tested extracellu...
