We derive a fundamental existence theorem for the equation u(t)'(x,t) - div(vertical bar del(x)u vertical bar(p-2)del(x)u) = 0 with continuous initial and boundary data in a space-tithe cylinder.

This paper deals with the construction and orbital stabilization of periodic solutions for a particular underactuated mechanical system with 2 degrees of freedom, the Furuta pendulum. It is shown that if a desired periodic motion is described by constraints imposed on the total energy of the system and on the value of the directly actuated variable, then this periodic motion can be constructed and

The purpose of building classification systems is to provide the sector with agreed and standardised ter¬minology and semantics, e.g. in systems for technical specification, cost calculation, and exchange of information. There is a growing need to use classification systems in a BIM context. In inter¬¬national construction projects and international construction product trade there is a need both

Within the newly decided scheme for CE-marking of cables1 a full-scale fire test for cables (prEN503992) has been introduced. The new test measures heat and smoke production rates and flame spread and in some cases requires large amounts of cables. In the project presented here a modelling tool was developed to predict full-scale results using data from the small-scale fire test Cone Calorimeter.

This paper introduces means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabi

A derivation for a polarized CCFM evolution equation which is suitable to describe the scaling behavior of the unintegrated polarized gluon density is given. We discuss the properties of this polarized CCFM equation and compare it to the standard CCFM equation in the unpolarized case.

Indications of what the tour-operating sector considers to be 'good practice' can be drawn from voluntary initiatives such as existing eco-labels and codes of conduct. However, practical implementation of such guidance varies greatly from one tour operator to another, depending on different types of factors, such as size, financial capacity, corporate structure, operational location, organizationa

Elater ferrugineus is a threatened click beetle inhabiting old hollow trees. Its larvae consume larvae of other saproxylic insects including the threatened scarab beetle Osmoderma eremita. Recently, (R)-(+)-gamma-decalactone was identified as a male-produced sex pheromone of O. eremita. Here we present evidence that E. ferrugineus adults use this odor as a kairomone for location of their prey. In

A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled hexahydrophthalic acid was used as the internal standard. The precisi

Summary: Overweight and obesity constitute a major and increasing health and welfare problem throughout the world. Assessing the multifaceted mechanisms – biological, environmental and behavioural – behind this development is a crucial task in medical, social and economic sciences. We are, therefore, grateful to have been given the opportunity to, once again, discuss whether the risk of divorce ma

Herbivory is an important part of most ecosystems, and grazing alone can have a considerable impact on the ecosystems carbon balance with both direct and indirect effects. Removal of above-ground biomass by consumption of herbivores will change the below-ground carbon stock; the reduction of litter that goes into the ground will influence the total ecosystem carbon content. Little is however known

We present a blow-up criterion for the periodic Camassa-Holm equation. The condition obtained for blow-up uses two of the conservation laws associated with the equation and improves upon some recent results.
