Mountain building and mantle dynamics

[1] Mountain building at convergent margins requires tectonic forces that can overcome frictional resistance along large-scale thrust faults and support the gravitational potential energy stored within the thickened crust of the orogen. A general, dynamic model for this process is still lacking. Here we propose that mountain belts can be classified between two end-members. First, those of “slab...

Physiological demands of mountain rescue work.

OBJECTIVE To characterise the physical fitness of mountain rescue (MR) volunteers and the physical demands of a typical MR callout. METHODS Eight MR volunteers (age ± SD: 45.5 ± 8.9 years) completed a laboratory-based treadmill exercise test to exhaustion. One week later subjects completed a field-based simulated callout to retrieve a casualty by stretcher. In both studies exercise intensity ...

Building Optical Constructions with Minimum Complexity

It is often claimed that future systems will necessarily be all-optical, because electronic devices are not fast enough to keep up with the increase in fiber capacity. However, two objections are commonly raised: first, optical systems need many basic optical components, which are typically very expensive; and second, optical systems need many switch reconfigurations, which are typically very s...

On Building Trees with Minimum Height, Relationally

Relationally Shin-Cheng Mu Computing Laboratory, University of Oxford s m omlab.ox.a .uk Abstra t The algebrai style of reasoning about programs has been proposed and studied by omputing s ientists. We rephrase the old problem of building trees of minimum height as an optimisation problem and apply the greedy theorem to derive a linear time algorithm. To put the problem in the right form, we nd...

The Minimum Energy Building Temperature Control

One of the most important factors of users comfort inside building is air temperature. From the other side one of the most biggest position in home budget is price for heat. Mutually exclusive indices are the cause that the control of temperature task using the smallest amount of energy as it is possible is very difficult. In this paper is presented simple model of temperature changes inside bu...
