Coloproctology

Coloproctology

R.J. Nicholls; J. Alexander-Williams; R. Glass

Springer-Verlag Berlin and Heidelberg GmbH Co. K
1985
nidottu
In this age of specialization most patients with diseases of the hind gut and anus are still managed by general physicians or surgeons. The speciality of coloproctology has grown from the art of 'anology', a study of conditions limited to that distance from the anal verge that could be inspected easily by torch- or candlelight or with the aid of a simple speculum. Two centuries ago many proctological ills were often treated by itinerant quacks, partly because the physician considered himself rather too grand to meddle around the anus and the medical profession in general tended to look down on those who studied anal disease. Today, in certain countries, coloproctology has become a speciality every bit as exclusive as urology or orthopaedic surgery, with its own training programme and examinations, usually undertaken after the end of general surgical training. Such super-specialization has undeniable advantages with rapidly advancing technology and therapeutic possibilities. There is no doubt that for the patient suffering from a low rectal carcinoma or severe inflammatory bowel disease there are advantages in being treated by surgeons who are dealing with several cases in a year rather than by a general surgeon who sees such problems relatively rarely. Such specialized colorectal surgery units makes good sense medically and economically in large centres of population with good communications.
The Control of Fish Migration

The Control of Fish Migration

nidottu
Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem. Migration brings fish into situations that allow easy harvest as they concentrate along migration routes. Their journeys also make them vulnerable to human intereference at critical points along their route. Salmon, for example, may harvest plankton in the open ocean and transport that food energy to coastal and inland regions, where it is captured by fisheries or deposited in inland streams and utilized by the flora and fauna of the region. These salmon are able to complete journeys of thousands of kilometers from their natal streams to oceanic feeding grounds and back to the same home streams, an accomplishment that strains our credi bili ty . We now understand some of the timing and guiding stimuli used in these migrations, and mechanisms can be logically proposed, on the basis of the established abilities of fishes, to account for the unexplained portions of the migrations. There is no single factor guiding these fish. Instead, they are dependent on the presence in their environment of a great variety of appropriate orienting and timing stimuli. These stimuli are vulnerable to human interference. The more widespread and easily available the information on these requirements, the more readily fish can be protected from such interference.

Discovering Mathematics with Maple

his book grew out of the wish to let students of econometrics get acquainted T with the powerful techniques of computer algebra at an early stage in their curriculum. As no textbook available at the time met our requirements as to content and presentation, we had no other choice than to write our own course material. The try-out on a group of 80 first year students was not without success, and after adding some necessary modifications, the same material was presented to a new group of students of similar size the year after. Some more adjustments were made, and the final result now lies before you. Working with computer algebra packages like Derive, Mathematica, and Maple over many years convinced us of the favourable prospects of computer algebra as a means of improving the student's understanding of the difficult concepts on which mathematical techniques are often based. Moreover, advanced mathematical ed­ ucation, be it for mathematics itself or for mathematical statistics, operations research and other branches of applied mathematics, can greatly profit from the large amount of non-trivial mathematical knowledge that is stored in a computer algebra system. Admittedly, the fact remains that many a tough mathematical problem, such as solving a complicated non-linear system or obtaining a finite ex­ pression for a multiple parameter integral, can not easily be handled by computer algebra either, if at all.
