D o you want your child to grow up to be a scientist? If so, then by all means follow the roadmaps set down by the 27 scientists who contributed their personal histories to John Brockman's Curious Minds: How a Child Becomes a Scientist. You could do worse than start with a family history rich in science, like Nicholas Humphrey whose grandfather, Nobel laureate A. V. Hill, remembers being startl...

At a time of global warming, growing environmental concerns and a political situation that is making many industrialised countries critically review their dependency on Middle Eastern oil, the need to develop alternatives to fossil fuels is becoming increasingly important. And this is not just a recurring demand from environmentalists; most industrialised countries signed the Kyoto Treaty, comm...

The historic discovery that the catecholamine neurotransmitters of the sympathetic nervous system, norepinephrine and epinephrine, are inactivated through their reuptake by presynaptic nerve terminals provided new insights into neurotransmitter action and paved the way for the development of modern antidepressant drugs.

Remarkable similarities in the vertical plane of forward motion exist among diverse legged runners. The effect of differences in posture may be reflected instead in maneuverability occurring in the horizontal plane. The maneuver we selected was turning during rapid running by the cockroach Blaberus discoidalis, a sprawled-postured arthropod. Executing a turn successfully involves at least two r...

Difficulty in turning while walking is common among patients with Parkinson's disease (PD). This difficulty often leads to significant disability, falls, and loss of function; moreover, turning is a common trigger for freezing of gait (FoG). We hypothesized that the quantity and quality of turning mobility while walking during daily life would be different among subjects with PD with and withou...

in this paper, the asymptotic representation of the corresponding eigenfunctions of the eigenvalues has been investigated. furthermore, we obtain the zeros of eigenfunctions.

the map and the model designed by a designer and presented to a manufacturer in the form of a map is the result of his knowledge and innovation. the manufacturer, in turn, uses his best effort to produce a part accordingly. however, because of production problems and raw material, producing a precise part is very difficult and costly. one of the most important problems in this regard is designi...
