T he many different fields of medical research can be categorized under three main headings: etiology (causes of diseases), pathophysiology (underlying mechanisms), and therapeutics (efficient ways to prevent or treat). In this issue of Circulation, the report by Momma et a1l on an experimentally created model of tetralogy of Fallot (TF) with absent pulmonary valve in rats is a remarkable examp...

Microclimatic design requires knowledge of the climate conditions, understanding of the ways that landscape elements affect microclimate and methods of applying this knowledge through landscape design to create microclimates that are comfortable for people and minimize the energy use of buildings. In this article it will be introduced the most important components and characteristics of microcl...

The ways for improving on techniques for finding new solvable potentials based on supersymmetry and shape invariance has been discussed by Morales et al. [1] In doing so they address the peculiar system known as the one-dimensional hydrogen atom. In this paper we show that their remarks on such problem are mistaken. We do this by explicitly constructing both the one-dimensional Coulomb potentia...

People have numerous ways of negotiating their interaction with imperfect technologies. Descriptions of these practices can be found scattered throughout literature, but always at the edges, or mentioned as interesting cases. Rarely (if ever) are forms of negotiated use the central focus. This paper develops the concept of negotiated use as way of engaging with technology that shares attributes...

Abstract The current techniques of communications using a chaotic carrier signal are presented. The different ways to achieve synchronization of chaotic systems are listed and some of the complex phenomena that arise in this context are mentioned. The role of synchronization of chaotic systems in digital communications is reviewed shortly. The point is made that progress in communications with ...

Ludwig Aschoff pointed out in his lectures on pathology that it is impossible to distinguish histologically between infections and regenerative and reparative inflammation. This means that the organism has few ways, or probably one essential way to act or react in its struggle for life and health. This is true not only for the above mentioned reactions but also for the causes which produce some...

This paper presents an overview of the essential nature of hypnosis as it is studied and practised today. Some theoretical controversies are mentioned and historical antecedents are briefly summarized. An overview is then presented of the ways in which hypnosis is applied therapeutically. It is concluded that although clinical hypnosis has yet to be informed by a strong academic base, progress ...
