JAMES HERRIOT'S YORKSHIRE REVISITED by James Herriot
Polymers are permeable, whilst ceramics, glasses and metals are gener- ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc- tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema- tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.
Herriot, James: - James Herriot (1916-1995) was the bestselling author of memoirs including All Creatures Great and Small, All Things Bright and Beautiful, All Things Wise and Wonderful, The Lord God Made Them All, and Every Living Thing. At age 23, Herriot qualified for veterinary practice with the Glasgow Veterinary College, and moved to the town of Thirsk in Yorkshire to work in a rural practice. He would live in, work in, and write about the region for the rest of his life. Though he dreamed for years of writing a book, his veterinary work and his family kept him busy, and he did not start writing until the age of 50. In 1979, he was awarded the title Order of the British Empire (OBE). His veterinary practice in Yorkshire, England, is now tended by his son, Jim Wight.
