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

Applying Phenomenology and Hermeneutics in IS Design: A Report on Field Experiences

Phenomenology and hermeneutics have long been promoted as sources of inspiration for better information system (IS) design. Practical approaches to applying these philosophical ideas have been awaited for just as long. This paper offers a review of one practitioner’s experience in devising a theoretical and methodological ‘toolkit’ via which these disciplines’ principles have been applied in actua

Flow optimization in IP networks with fast proactive recovery

The post-failure convergence of the shortest path routing (SPR) protocols used in IP networks can be too slow to meet the restrictive requirements (i.e., maximum allowable delay, jitter, etc.) of the multimedia services and therefore new restoration mechanisms combined with IP routing are of interest. The paper addresses optimization of three potential rerouting mechanisms based on the IP fast rer

The adsorption and charge transfer dynamics of bi-isonicotinic acid on Au(111)

The interaction of bi-isonicotinic acid (4,4[prime]-dicarboxy-2,2[prime]-bipyridine) with the Au(111) surface has been investigated using electron spectroscopic techniques. Near edge x-ray absorption fine structure (NEXAFS) spectra show that monolayers of the molecule lie flat to the surface and also reveal that the monolayer is sensitive to the preparation conditions employed. Core level x-ray ph

Diffusive-Ballistic Heat Transport in a Two-Dimensional Square Plate Using Energy Conserving Dissipative Particle Dynamics

Diffusive-ballistic heat transport in a two-dimensional square plate was simulated using energy conserving dissipative particle dynamics (DPDe). The solution domain was considered to be a two-dimensional square plate surrounded by walls at constant temperatures, where DPD particles are uniformly distributed. The effects of phonon mean free path was incorporated by its relation to the cutoff radius
