To survive, organisms must avoid predation and acquire nutrients and energy. Sensory systems must correctly differentiate between potential predators and prey, and elicit behaviours that adjust distances accordingly. For snakes, strikes can serve both purposes. Vipers are thought to have the fastest strikes among snakes. However, strike performance has been measured in very few species, especia...

The decomposition procedure suggested for magnetotelluric (MT) data in a companion paper is illustrated by examples. Adjacent pairs of stations are examined to test for common features in their MT response. The method analyzes the real and quadrature parts of an impedance tensor separately, and the results for the real and quadrature parts are compared, and in some cases combined, at the end. V...

Running performance, energy requirements and musculoskeletal stresses are directly related to the action-reaction forces between the limb and the ground. For human runners, the force-time patterns from individual footfalls can vary considerably across speed, foot-strike and footwear conditions. Here, we used four human footfalls with distinctly different vertical force-time waveform patterns to...

Blowfly strike of sheep can be represented as part of the fly life cycle (Fig-1). Our objective is to identify and quantify important factors promoting progression through the cycle so as to be able to predict the timing and impact of one particular part of the cycle viz. the development of fly larvae on sheep or 'strike'. In Fig-l, some of the factors believed to be important for the developme...

Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...

‘Non sibi sed omnibus’. Not for one but for all. This is the overriding principle in the mind of all doctors while practising their vocation. The care and welfare of patients are the primary considerations of the medical profession. Seldom do you see a doctor who prioritizes his interests before those of his patients. If patient care is the issue, he will disregard any amount of inconvenience c...

For the more than 300 million people who suffer migraines, the excruciating, pulsating pain that characterizes these debilitating headaches needs no description. For those who do not, the closest analogous experience might be severe altitude sickness: nausea, acute sensitivity to light, and searing, bedconfining headache. “That no one dies of migraine seems, to someone deep into an attack, an a...

Aircraft repeatedly prove that birds and aircraft cannot occupy the same airspace at the same time. In an average year about 3000 birdstrikes cause 50-80 million US dollars in damage to USAF aircraft. To the worldwide aviation fleet this problem is estimated to cost more than three billion US dollars per year. Factors for consideration in establishing birdstrike resistance requirements, and in ...
