Pick data on parallel exchange rates are widely popular among economists. However, such data may contain inaccuracies and their use may produce misleading results in empirical research. Criteria are defined to assess their quality as go...

The aim of the paper is to summarize some work by the author on the theory of sugar boiling. The boiling of sugar in vacuum pans has been modelled with a set of interconnected differential and integral equations. The model equations are...

Loss of radioactivity to the aqueous phase of conventional extraction procedures has been observed in studies of glyceride synthesis with labeled fatty acids. A method is presented which does not involve washing procedures and by which ...

I pondered for a long time whether to write this article. It concerns the terrible barbarism of war committed against computer equipment which should make any average person shudder with sadness. As part of the subject matter of CLSR is...

We study the existence of positive solutions of a nonlinear eigenvalue problem for a two-point boundary-value problem for a family of second-order disfocal ordinary differential equations. We apply a cone-theoretic fixed-point theorem a...

It is shown that on closed disks D around the origin in the complex plane and for every integer m ≥ 2, not every continuous function on D can be approximated uniformly on D by polynomials in zm and <img height="31" border="0" style...

We systematically analyze the Nike Lunar correlations between the various leptonic and hadronic flavor violating processes arising in SUSY Grand Unified Theories. Using the GUT-symmetric relations between the soft SUSY breaking paramete...

A spring was inserted between the shafts of a conventional Hegar needle holder. This facilitates the palm grip handling and does not interfere with the thumb-finger grip, resulting in a more versatile instrument. Some basic assumptions...

Recently, I have been impressed to learn that so much is going on which combines my two passions: aviation and GaAs! In Europe, Israel and the USA, GaAs-based circuit technology is still being substantially funded for research but bette...

We report a case of left brachiocephalic vein thrombosis, acute pulmonary embolus, and contraindication to anticoagulation treated with superior and inferior vena caval filters. (J VASC SURG 1995;22:501-4.) Recent pioneering advances i...
