— This paper offers a conceptually straightforward method for the calculation of stresses in polarisable media based on the notion of a drive form and its property of being closed in spacetimes with symmetry. After an outline of the notation required to exploit the powerful exterior calculus of differential forms, a discussion of the relation between Killing isometries and conservation laws for...

Choosing a career within the military has many positive and negative factors associated with it. For instance, many recruits join as young adults when they are beginning to shape their own values, beliefs and attitudes about their self, world and others. The armed forces (AF) culture socialises these young adults, leading them to adopt military values and ideals as their own which they will pro...

“We are without allies amongst the Iraqi populace, including those who have benefited from the ouster of Saddam. . . . Across Baghdad, Latifiyah, Mahmudiyah, Salman Pak, Baqubah, Balad, Taji, Baiji, Ramadi, and just about everywhere else you can name, the people absolutely hate us. . . . The Iraqi people have not bought into what the Americans are selling, and no amount of military activity is ...

BACKGROUND For surgical reconstruction of lateral pinch following tetraplegia, the function of the paralyzed flexor pollicis longus is commonly restored. The purpose of this study was to investigate if one of the intrinsic muscles could generate a more suitably directed thumb-tip force during lateral pinch than that of flexor pollicis longus. METHODS Endpoint force resulting from 10 N applied...

The spinal neurocoel normally occludes during the second day of chick embryogenesis as the lateral walls of the spinal cord become apposed closely in the midline. Concomitantly, the brain initiates its rapid and substantial enlargement. Occlusion, although short-lived, might play a major role in brain enlargement. As a result of occlusion, the brain ventricles are sealed off from the external m...

This is a small pattern language for running online trainings. The language starts with an entry pattern ONLINE TRAINING. All other patterns are supporting this pattern and help to make online trainings more alive. Some of the patterns are not exclusive for online uses, for instance PREPARED EXAMPLE or TEST RUN. These patterns could be part of a pattern language for trainings as well. They are ...

The diagram of forces mentioned in the well-known quote from D’Arcy Thompson’s biblical book can be recognised in various guises throughout the reviews in this special issue of Current Biology on cell form and physics. The force diagram is perhaps most strikingly apparent in a structure that has not terribly much to do with cell shape per se — the mitotic spindle, discussed by Sophie Dumont and...
