Characterisation and modelling of washover fans

Pre- and post-storm topography and aerial photography, collected in regions where new washover fans were formed, were studied to determine the extent of morphologic, vegetative and anthropogenic control on washover shape and extent. When overwash is funnelled through a gap in a dune ridge and then spreads laterally on the back barrier, decelerating and depositing sediment, it forms washover fans.

p38 Mitogen-activated protein kinase and phosphatidylinositol 3-kinase activities have opposite effects on human neutrophil apoptosis.

Neutrophil apoptosis is essential for resolution of inflammatory reactions. Here, we studied the role of two apoptosis/survival-associated protein kinases in this process. We discovered a previously undetected early and transient inhibition of the activity of p38 mitogen-activated protein kinase (p38 MAPK) during both spontaneous and Fas-induced apoptosis. Pharmacological inhibition of this enzyme

Effects of spreading bandwidth on the performance of UWB RAKE

We consider an ultra-wide bandwidth system using reduced-complexity RAKE receivers, which are based on either selective (called SRake) or partial (called PRake) combining of a subset of the available resolved multipath components. We investigate the influence of the spreading bandwidth on the system performance using the two considered types of RAKE receivers. We show that, for a fix number of RAK

Statistical analysis of the UWB channel in an industrial environment

In this paper, we present a statistical model for the ultra-wideband (UWB) channel in an industrial environment. Based on a set of measurements in a factory hall, we find that the abundance of metallic scatterers causes dense multipath scattering. This can be seen to produce mostly a Rayleigh distributed small-scale fading signal, with only a few paths exhibiting Nakagami distributions. For the po

Capturing the Transnational: A Conceptual History

The chapter traces the origin and development of a set of interconnected concepts used to capture the transnational. In addition to the adjective "transnational," these include "non-governmental organizations," "global civil society" and "networks."

An excretory organ in the Mystacocarida (Crustacea)

An excretory antennal gland, composed of only eight cells, is found entirely in the limb in the mystacocarid Derocheilocaris typica. The end sac is composed of podocytes, valve cells and cap cells. The podocytes contain enormous residual vesicles. There are few pedicel complexes, and they arise directly from the cell surface without intermediate foot processes. The excretory duct is entirely lined

Effect of an intervention addressing working technique on the biomechanical load of the neck and shoulders among hairdressers

The purpose of this study was to describe, and analyse the effect of an intervention on, the biomechanical workload in the neck and shoulder region of female hairdressers. Arm elevation was measured by inclinometers and muscular load of m. trapezius by electromyography. The intervention comprised working technique recommendations, e.g. to work with less elevated arms and more relaxed muscles. The

A general approach for determining dynamic forces in spur gears

A model is presented taking into account off line-of-action, non linear wheel stiffness by using the finite element method, and elasticity coupling between the gear teeth. The contact points are determined by searching the common normal using the undeformed, but otherwise true theoretical, tooth shapes where the teeth have a tip rounding to prevent contact singularity in off-line-of-action points.

Transnational Actors in Global Governance: Patterns, Explanations, and Implications

The volume analyzes the reasons behind, and consequences of, the growing involvement of transnational actors in established international institutions. It provides comparative analyses of varying international organizations and issue-areas. Combining normative democratic theory and empirical research, it offers innovative interpretations of the democratic legitimacy of current arrangemants.

The cognitive profile of anorexia nervosa: a comparative study including a community-based sample

A community-based sample of adolescent-onset anorexia nervosa (AN) cases (n = 51) was contrasted with an age-, sex-, and school-matched comparison group [comp] (n = 51) on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) at a mean age of 21 years. There were no study dropouts. Fewer than 10% of AN cases were underweight at the time of testing. Overall, there were few differences across the t

Scheduling of Conditional Process Graphs for the Synthesis of Embedded Systems

We present an approach to process scheduling based on an abstract graph representation which captures both data-flow and the flow of control. Target architectures consist of several processors, ASICs and shared busses. We have developed a heuristic which generates a schedule table so that the worst case delay is minimized. Several experiments demonstrate the efficiency of the approach.

Citizen-Consumers and Evolution: Reducing Environmental Harm through Our Social Motivation

[Based on the publisher's comments:] This book reflects upon and critiques the potential of citizen-consumer's to alter their natural consuming habits and to 'shop ethically, 'care for the environment' and 'think glocally' so as to reduce environmental harm. Developing a substantial challenge to the existing accepted theories, this book sets out a groundbreaking approach to understanding citizen-

A helping hand? Gestures, L2 learners, and grammar

This chapter explores what L2 learners' gestures reveal about L2 grammar. The focus is on learners’ difficulties with maintaining reference in discourse caused by their incomplete mastery of pronouns. The study highlights the systematic parallels between properties of L2 speech and gesture, and the parallel effects of grammatical development in both modalities. The validity of a communicative acco
