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...

Line 5 in the first paragraph of [1] under the section Option basics appeared as follows: “A call option gives the buyer of the option the right to buy the underlying asset at a fixed price (strike price or K) at any time prior to the expiration date of the option.” It is commonplace in derivatives literature to denote the strike or exercise price as K (e.g., refer to http://www.duke.edu/∼charv...

1998, vol. 53, n° 2 0034-379X In this paper, I adopt a critical sociological approach to analyse how labour law shaped a 23-day strike at a western Canadian university in the fall of 1995. I begin with a brief discussion of the sociological alternative. Next, I provide a chronology of the strike, followed by a brief analysis of how both economic and sociological models contribute to understandi...

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...

The importance of tectonics and fluid flow in controlling cold seep habitats has long been appreciated at convergent margins but remains poorly understood in strike-slip systems. Here we present geophysical, geochemical, and biological data from an activemethane seep offshore fromDelMar, California, in the inner California borderlands (ICB). The location of this seep appears controlled by local...

In this paper, we compare five engineering return stroke models, extended to include the presence of an elevated strike object, namely the Bruce–Golde (BG) model, the transmission line (TL) model, the traveling current source (TCS) model, and the two modified TL models (MTLL and MTLE). The model-predicted current profile along the channel and along the strike object, as well as radiated electri...

The aim of the study was to establish whether the physicians' strike, which took place in Croatia in 2003, had an impact on the mortality of the population. Mortality data from the National Bureau of Statistics relating to the strike period (15 January - 14 February 2003) were selected and compared with the previous and subsequent periods of the same duration in 2001, 2002 and 2004. Of the 52,5...

Electric power utilities face increasing demand for service reliability. Since cloud-toground lightning strikes are among the most frequent yet least understood causes of service interruption, predicting the geographical and temporal distribution of the lightning strikes can help power system planners and designers improve the protection of new and existing transmission lines. Lightning is the ...
