As everyone knows, an atom is the smallest unit of a chemical element, and atoms combine to form molecules and solids. Each element is uniquely specified by its atomic number Z. However a given element may occur in several different versions, called isotopes; these have the same Z but different atomic mass number A. A glance at the periodic table shows that for the naturally occurring elements ...

The goal of the I.M.O.G.E.N.E. project is to define a real time graphics system. We focus on true real time display, images being computed at frame rate, i.e 50 (or 60) times a second. The I.M.O.G.E.N.E. machine uses no frame buffer. We use a massive object parallelism; the graphics module is made of a large number of object-processors, each one handling one graphics primitive at pixel rate in ...

Here, we present determinants of some square matrices of field elements. First, the determinat of 2 ∗ 2 matrix is shown. Secondly, the determinants of zero matrix and unit matrix are shown, which are equal to 0 in the field and 1 in the field respectively. Thirdly, the determinant of diagonal matrix is shown, which is a product of all diagonal elements of the matrix. At the end, we prove that t...

We present some language-specific tools for the development of Modula-2 program systems. Specifically, we elaborate on an extended Modula-2 syntax checker, a makefile generation utility, a Modula-2 structure analyser and a cross reference utility.

In the past few decades the West has witnessed an explosion of interest among psychologists, theologians, scientists, and philosophers alike in what Huxley (1970) has called philosophia perennis,the 'perennial philosophy', a universal doctrine as to the nature of man and reality lying at the very heart of every major metaphysical tradition, whether that of the Hindus, the Buddhists, the Amerind...

  Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems  to be induced at low doses of exposure. In recent decades, however, some pioneer scientists have indicated that ionizing radiation like many other essential agents has toxic effects  ...
