Throughout this paper R denotes an associative ring with identity and all modules are unitary. We use the symbol U(R) to denote the group of units of R and Id(R) the set of idempotents of R, Un(R) the set of elements which are the sum of n units of R, UΣ(R) the set of elements each of which is the sum of finitely many units in R, RE(R) (URE(R)) the set of regular (unit regular) elements of R, a...

On the face of it all this sounds hygienically excellent, but as far as achievement of a national supply of clean milk is concerned there is still one very weak point. Dairymen are in no way legally bound to hold these licences. If the public is foolish enough still to accept heavily infected milk, it will be delivered to them indefinitely. The local health authority cannot compel the productio...

Pet birds, being previously unexposed to the many dangers of our industrial world, are prime candidates for the ingestion/inhalation of toxins. What follows is a highlight of the most common toxins found in our homes. These will include "acute" fast acting fatal toxins and the "chronic" more long term, but still deadly types of toxins. REMEMBER: WHEN CONSIDERING IF A PRODUCT MIGHT BE TOXIC OR N...

The modified adaptive Chirplet decomposition (MACD) is presented in this paper. It is based on the extension of the traditional Chirplet atoms to the form of the quadratic frequency-modulated signals. The accuracy of the signal decomposition is improved compared with the traditional Chirplet decomposition. A practical algorithm for the parameters estimation of monocomponent MACD atom and the de...
