Magnetotelluric Studies of Active Continent–Continent Collisions
Continent–continent collisions are an important tectonic process and have played a fundamental role in the evolution of the modern continents. A combination of geological and geophysical data has provided new constraints on the structure and temporal evolution of these orogens. Magnetotelluric (MT) studies have been an important part of these studies since they can constrain the fluid content a...
متن کاملThe Conseal Continent Colostomy Appliance
The concept of a continent stoma is an attractive one. This has been achieved with varying success for ileostomies made with a Koch pouch but not for colostomies. Permanent ileostomies, and to a proportionally lesser extent colostomies also, are becoming increasingly rare following increased expertise in sphincter saving operations, mucosal proctectomy and the success of the Jand W-ileoanal pou...
متن کاملDiarrhoea after continent ileostomy.
To determine the nature and frequency of malabsorption in patients with continent ileostomies, faeces and urine from 42 patients with ileal pouches and from 19 patients with conventional ileostomies were analysed and compared. The patients with conventional ileostomy were matched with patients with ileal pouches. Thirteen of the patients with pouches were found to have excessive faecal volumes ...
متن کاملMagnetic continent colostomy device.
For patients, the principal drawback of a colostomy is the loss of faecal continence. To achieve a continent colostomy has long been the goal of surgeons. A magnetic stoma seal became feasible when a strong, light, durable magnet made of samarium-cobalt became commercially available in 1972. This metal compound has the highest magnetic energy per unit volume and loses only a few per cent of its...
متن کاملThe Missing “Missing Middle”
T he notion that the distribution of firm size in poor countries is characterized by a bimodal distribution with a “missing middle” is a widely accepted fact in development economics (for example, see Krueger 2013). The idea of the missing middle is that there are a large number of small firms, some large firms, but very few medium-sized firms. The purported fact about the missing middle is cit...
