This research places self-handicapping and defensive pessimism (comprising defensive expectations and reflectivity) into a single conceptual and analytic framework that models the full self-protective process across time. Data on two occasions collected during students (n 1⁄4 328) first two years at university show: performance orientation positively predicts self-handicapping, defensive expect...

measurement of the skin especially to monitor epidermal thickness during clinical trials: • study of the effect of UVA1 and UVB on epidermal thickening [6] ; • study of age-related skin changes [7] . It is more suitable than high-frequency ultrasound to explore the epidermis and dermo-epidermal junction. In this issue of Dermatology , Mogensen et al. [8] used an OCT system developed at Risoe Na...

First of all, I will introduce the basics of Newtonian fluids, followed by differences in comparison to non-Newtonian fluids. Following that, I will consider suspensions and focus on the shear thickening phenomena. Different theories behind that lead us to an order-disorder system and a hydro-clusters formulation. Finally, I will present its applications and prospects for the future.

Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is due to hydrodynamic clusters has been challenged by recent theory and simulations suggesting that contact forces dominate, not only in discontinuous, but also in continuous shear thickening. Here, we settle this dispute...

The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...

The propagation of torsional waves in a prestressed fiber-reinforced half-space under the effect of magnetic field and gravity has been discussed. The problem has been solved analytically using Whittaker function to obtain the exact solution frequency equations. Numerical results for stress, gravity and magnetic field are given and illustrated graphically. Comparisons are made with the results ...
