1.9 Summary

  1. In a basic model of signal transduction, a signalling molecule binds to a specific receptor, and this activates a sequence (or web) of intracellular signalling molecules that spread the information to relevant parts of the cell, activating target molecules, which effect a cellular response.

  2. Signalling between cells can be contact dependent or via secreted signalling molecules. The latter comprise paracrine, autocrine, endocrine or electrical s

The 'mop fair' is an annual custom in Stratford-upon-Avon dating back to medieval times. Traditionally held in October, when labourers and apprentices would come to the town seeking work, the fair culminates in the roasting of a whole ox, as can be seen in this evocative Topical Budget newsreel item. The practice, which continues to this day, was described by historian Charles G. Harper in the 1930s as "an offence to people of delicate sensibilities". All titles on the BFI Films channel are pre

Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w

7.1 Introduction

So far we have presented two pieces of evidence pointing to the occurrence of a big bang: the redshift of the galaxies (indicating the continuing expansion of the Universe), and the 3 K radiation (the remnant of the primordial radiation). But there is a third imprint such a big bang ought to have left on our present-day world. We cannot at this juncture trace out the full sequence of events following the instant of the big bang (that can only be done after we have worked through the next two
