A common problem which arises in many complex applications is to solve a sequence of linear systems of the form: Akxk = bk, for k = 1, 2, .. In these applications Ak does not generally change too much from one step k to the next, as it is often the result of a continuous process (e.g. Ak can represent the discretization of some problem at time tk.) We are faced with the problem of solving each ...

THE 'plasmal reaction' has been widely used in cytology, and is generally interpreted as revealing the presence of aldehydes, but there is considerable doubt as to their source. According to Feulgen and his collaborators, who first described the reaction, the aldehydes (plasmal) are formed by decomposition of acetalphosphatides (plasmalogen) under the catalytic influence of mercuric chloride. A...

Aristotle (384-322 BCE) can be attributed with the earliest recorded comments regarding the manner in which humans walk. It was not until the renaissance that further progress was made through the experiments and theorising of Giovanni Borelli (1608-1679). Although several scientists wrote about walking through the enlightenment period it was the brothers Willhelm (1804-1891) and Eduard (1806-1...

As far back as 1870, i.e., about 150 years ago, Jules Verne described the accumulation of debris in the convergence zone of the North Atlantic Ocean in his famous novel entitled “Twenty Thousand Leagues under the Sea.” Many scientific reports have addressed this topic since and our main concern today is the ever increasing volume of marine litter invading the oceans in various and complex ways....

I MUST thank you for the great honour which the Council of the Society has done me in asking me to be your President for the incoming session. I appreciate the honour greatly, though it entails certain responsibilities, not the least being this agony of words, usually called the Presidential address. Even the choice of a subject worthy of the occasion gives cause for thought. I could deal with ...
