The results of flow experiments for several kinds of ash are presented. The experiments were carried out on the two laboratory stands at the Institute of Environmental Engineering, Agricultural University of Wroclaw. The pressure drop, limit deposit velocity, mixture density distribution in a cross-section of pipeline and pump characteristics are measured during these experiments. The measurements of density distribution were carried out by means of a device based on radiometric scanning, which enables us to determine these parameters without causing disturbances in the flow. The problem of limit concentration between Newtonian and non-Newtonian behaviour of mixtures is also discussed. The results of investigations into parameters of hydrotransport of ash and brine mixture in pipelines (80 and 100 mm) are presented. The investigations were carried out on the test laboratory installation at the Silesian Technical University of Gliwice.

Signalling: basics and evolution

Signalling concerns the transfer of information from one body, a source, to an­other, a receiver in order to stimulate activity. The problem arises with the word in­formation. It is defined as what is transferred in a sequence of things, say between people, e.g. words or signs. The idea of signalling between people is then obvious but it is not clear in cell biology. Information transfer, signalling, is required for the or­ganisation of all cellular activity but we must ask what is transferred and how is it transmitted and received? Sometimes it is assumed that all information, i.e. organi­sation in a cell, is represented in the DNA sequence. This is incorrect. We shall show that the environment is a second source of information concerning material and en­ergy. The receiving party from both DNA and the environment is general metabo­lism. The metabolism then signals back and sends information to both DNA and up­take from the environment. Even then energy is needed with machinery to send out all signals. This paper examines the way signalling evolved from prokaryotes through to man. In this process the environmental information received increased to the extent that finally the brain is a phenotypic as much as a genotypic organ within a whole organism. By phenotypic we mean it is organised by and interactive with infor­mation from the environment.
