The concept of molecular structure is one the most important concepts in the development of the scientific knowledge of the XX century. As a matter of fact the reasoning based on the molecular structure has been the main engine for the great development of physical chemistry, molecular physics, organic chemistry, quantum chemistry, chemical synthesis, polymer chemistry, medicinal chemistry, etc...

In the present paper we consider fibrations f : S → B of an algebraic surface onto a curve B, with general fibre a curve of genus g. Our main results are: 1) A structure theorem for such fibrations in the case g = 2 2) A structure theorem for such fibrations in the case g = 3 and general fibre nonhyperelliptic 3) A theorem giving a complete description of the moduli space of minimal surfaces of...

We distinguish two conceptions of sample and sampling that emerged in the context of a teaching experiment conducted in a high school statistics class. In one conception 'sample as a quasi-proportional, small-scale version of the population' is the encompassing image. This conception entails images of repeating the sampling process and an image of variability among its outcomes that supports re...
