(2) STERILISING FILTERS

Removal of radioisotopes in solution and bactericidal/bacteriostatic sterilising power in activated carbon and metal silver filters.

Activated carbon filters play an important role in water filtration and purification from contaminants of different origin. Their limit consists in bacterial proliferation, which may occur only during prolonged periods of non-use and in their ability to remove radioactive contaminants present in waste water from Industry or Nuclear Medicine departments. In this work we tested a commercially ava...

On sterilising severely mentally handicapped people.

At the time of writing, the House of Lords in England had not ruled in the case ofJeanette-a seventeen-year-old with allegedly the skills of at most a five or six-year-old whose mother and gynaecologist wished to perform probably irreversible sterilisation by an operation to tie her fallopian tubes (1). Whatever the legal decision, the ethical issues underlying decisions of this kind deserve an...

Semi-G-filters, Stonean filters, MTL-filters, divisible filters, BL-filters and regular filters in residuated lattices

At present, the filter theory of $BL$textit{-}algebras has been widelystudied, and some important results have been published (see for examplecite{4}, cite{5}, cite{xi}, cite{6}, cite{7}). In other works such ascite{BP}, cite{vii}, cite{xiii}, cite{xvi} a study of a filter theory inthe more general setting of residuated lattices is done, generalizing thatfor $BL$textit{-}algebras. Note that fil...

Multiplierless implementation of 2-D FIR filters

In this paper, the multiplierless design of two-dimensional FIR filters is studied. The adders that are used in place of multiplications are reduced by using the 2-D CSE (CommonSubexpressionElimination) method which is developed in this paper. This method decomposes the original filter into smaller filters and the output of each filter is scaled with an appropriate coefficient to form the origi...
