Lowered excretion indicates diminished intestinal absorption usually caused by a decreased absorptive surface, infiltrative intestinal disease, or bacterial overgrowth.
The larger its internal surface, the greater its absorptive efficiency, and a spiral valve is one method of increasing its absorption surface.
In the Journal of Glaciology this week, Peter Kuipers Munneke of Utrecht University in the Netherlands and his colleagues argue that this absorptive power is crucial to the stability of the world's ice shelves and therefore of the global sea level.
The real problem is of absorptive capacity, not external resources".Most contentiously, South Africa will not widely distribute anti-retroviral drugs until its concerns about long-term costs, dependence on foreign companies and safety are assuaged.
In one respect its reliance on the absorptive qualities of plastics—it is similar to the design used by Dr Lewis.
Indeed, even after a dozen immersions in oil, for between 15 and 20 seconds each time, the wool's absorptive capacity did not decline.Technology Quarterly Cameras get cleverer Drops to drink Formula 1 goes sailing Zapping fakes with lasers Particle physic A golden fleece Joining the drones club Reducing the barnacle bill What would Jesus hack?
When dark, absorptive seawater replaces bright, reflective ice, it retains more heat.
Weaken an ice shelf enough in this way and it will disintegrate, as happened to the Larsen B shelf in Antarctica in 2002.Worryingly, according to Dr Kuipers Munneke, rising temperatures mean firn's absorptive capacity is shrinking, as the volume of meltwater exceeds the capacity of the new firn created by fresh snowfalls to suck it up.
But there are limits to their absorptive capacity.
The absorptive power of local democracy is great, but it is not infinite.
