The recommended duration of an aerobic exercise session is dependent on several factors, such as the participantâ€™s goals and fitness levels, and the intensity of exercise. Obviously, the higher the intensity of the exercise, the shorter will be its duration. The ACSM 2011 position stand recommends 30-60 minutes of purposeful moderate exercise per session, 20â€“60 minutes of vigorous exercise per session, or 20â€“60 minutes of a combination of moderate and vigorous exercise per session for h

Type 1 diabetes was previously called insulin-dependent diabetes. This is because in people with Type 1 diabetes their pancreas fails to produce insulin and they are dependent on taking insulin for their treatment. It would be useful to look back at Figure 5 to remind yourself of the actions of insulin. As we have already discuss

At an interface with the atmosphere, water changes its state from a liquid to a vapour in response to an increase in temperature caused by an external heat source. This temperature change is normally the result of solar radiation. The transfer of moisture into the air is called evaporation. The process is also controlled by the relative humidity, or level of vapour saturation, of the air. The greater the relative humidity of the air, the less likely it is that evaporation will take place for

Hilary Cremin et al. (2003), in their evaluation of the ways in which teachers and teaching assistants can work together in teams, suggest that, while there is enthusiasm for additional support, little attention is given to how this actually works in classrooms. It is true that learning support staff have been introduced into classrooms without clear research evidence that they can make a difference to childrenâ€™s learning, but then life often moves faster than the supply of research evidenc

So far we have suggested that innovation is a positive concept and, it appears, the rate of innovation continues to accelerate, led mostly by technology. The process is an example of positive feedback, in which the change is self-reinforcing: the development of technology itself increases the capacity for technological innovation, and raises the expectation of consumers for further innovation. While there seems little reason why this process of accelerating technological change should

Compressive and tensile deformation in bubble raft
Bubble raft undergoing compressive and tensile deformation. At small strains, the arrangement of the bubbles does not change. This is elastic deformation of the raft. The bubbles change shape and move slightly apart in an effort to maintain the lowest energy close-packed configuration. At larger strains, plastic deformation occurs. The bubble raft rearranges by dislocation motion. From TLP: Introduction to dislocations, http://www.msm.cam.ac.uk/doitpoms/tlplib/dislocations/dislocation_motion.php
