This instructional design project examined whether an instructional design module, in the form of a video lesson in DVD format, could be an effective method of delivering consistent, anytime, anywhere instruction for a secondary automotive technology course. Design elements that were investigated included those derived from cognitive theories of multimedia learning, such as signaling, spatial c...

Several factors contribute to organ dysfunction in septic shock patients, and once the inflammatory response has been activated, many organ systems can be adversely affected. A marked fall in systemic vascular resistance results from arterial and venous dilatation. This is accompanied by leakage of plasma into the extravascular space, leading to relative hypovolemia. The microcirculation is adv...

Researchers often calculate ratios of measured quantities. Specifying confidence limits for ratios is difficult and the appropriate methods are often unknown. Appropriate methods are described (Fieller, Taylor, special boot-strap methods). For the Fieller method a simple geometrical interpretation is given. Monte Carlo simulations show when these methods are appropriate and that the most freque...

A light-dependent in vitro protein-synthesizing system from isolated mesophyll chloroplasts of Sorghum vulgare was characterized. Preincubation of chloroplasts in light at 25 degrees C for 1 h depleted the endogenous templates completely; such preincubated chloroplasts translated exogenously added homologous, heterologous, and synthetic templates efficiently. The fidelity of the system in trans...

In this paper we prove that every proper convex and lower semicontinuous functional de ned on a real re exive Banach space X is semicoercive if and only if every small uniform perturbation of attains its minimum value on X.

Let R be an o-minimal field with a proper convex subring V . We axiomatize the class of all structures (R, V ) such that kind, the corresponding residue field with structure induced from R via the residue map, is o-minimal. More precisely, in [8] it was shown that certain first order conditions on (R, V ) are sufficient for the o-minimality of kind. Here we prove that these conditions are also ...

fifty years ago warren and root have introduced the shape factor. this fundamental parameter for modeling of naturally fractured reservoirs has been discussed stormily ever since. different definitions for shape factor have been suggested which all of them are heuristically based. recently, heinemann and mittermeir mathematically derived - based on the dual-continuum theorem assuming pseudo-ste...
