Composites are presently the most developing and particularly attractive special-purpose construction materials for ballistic applications, among others. They are the basic raw materials used in the production of composite ballistic shields, such as shrapnel and bullet-proof helmets, means of transport armour, bullet-proof shields, explosion protection, additional ballistic insets for shrapnel ...

If rational individuals pay the full costs of their decisions about food intake and exercise, economists, policy makers, and public health officials should treat the obesity epidemic as a matter of indifference. In this paper, we show that, as long as insurance premiums are not risk rated for obesity, health insurance coverage systematically shields those covered from the full costs of physical...

Many studies have demonstrated that the exposure of nuclear medicine technologists arises primarily from radioactive patients rather than from preparation of radiopharmaceuticals. However, in order to devise strategies to reduce staff exposure, it is necessary to identify the specific tasks within each procedure that result in the highest radiation doses. An ESM Eberline FH41B-10 radiation dose...

Abstract The operational approach to time is a cornerstone of relativistic theories, as evidenced by the notion proper time. In standard quantum mechanics, however, an external parameter. Recently, many attempts have been made extend mechanics within relational framework. Here, we use similar ideas combined with mass-energy equivalence study accelerating massive particle internal clock system. ...

Fernandez (2004b) argues that the present value effect of the tax saving on debt cannot be calculated as simply the present value of the tax shields associated with interest. This contradicts standard results in the literature. It implies that, even though the capital market is complete, value-additivity is violated. As a consequence, adjusted present value formulae of a standard sort cannot be...

A new relationship between the roughness height and the main hydrodynamic and sediment parameters for plane beds under oscillatory conditions is presented. In order to derive such a relationship, a large data base encompassing plane-bed experiments was compiled from previous investigations and analyzed. Different methods to estimate the roughness height were investigated. Comparisons between th...
