Popular Abstract in Swedish Hydrofob pervaporation är en lovande teknik för återvinning och anrikning av aromer under milda betingelser men kommersiella tillämpningar av denna process är fortfarande outvecklade. Bättre kunskap om masstransportfenomen i kompositmembran avsedda för pervaporation behövs för utveckling av membran medan processimulering är ett viktigt verktyg för att optimera modulutfoHydrophobic pervaporation has gained a lot of attention as an alternative process for mild aroma recovery, but the real commercial applications of this process are still in their infancies. Better understanding of mass transport phenomena in composite pervaporation membranes is essential from the point of view of membrane manufacturing, while process simulation is an important tool for predicting

In this chapter, we present a model for the reactive-transport of chemical species through partially saturated porous media for electrokinetic remediation processes. A generalized theoretical model is presented, easily adaptable to specific remediation setups, target contaminants and supporting matrices; and we give detailed guidelines for the implementation of tailor-made numerical methods for th

A dynamic multi-link MIMO channel indoor measurement campaign at 5.3 GHz is presented in this paper. The system setup is described and capacity with interference (with and without power control) results based on the dynamic multilink MIMO measurements are shown, and we experience a strong correlation between the relative capacity and SIR. Furthermore, an interference suppression metric is introduc

The temperature distribution in concrete structures varies due to annual and daily climate variations. Solar radiation, air temperature, wind speed and long-wave radiation affect the temperature in the structure and may cause longitudinal and transversal movements. If these movements are restrained, stresses and strains can be induced which may contribute to cracking. To be able to predict the lon

This report covers the project period from 1.4.2003 to 31.08.2005. Project organisation, administration including the accounts, and the work carried out are reported. Besides, suggestions for copyright are put forward together with plans for dissemination activities and need for further research. The NAME was developed by the project group, consisting of all partners who have all contributed in an

The aim of this study was to assess prospectively the long-term outcome in a representative sample of teenage-onset anorexia nervosa (AN) in respect of psychiatric disorders and overall outcome. Fifty-one AN cases, recruited by community screening, with a mean age of onset of 14 years, was contrasted with 51 matched comparison cases at a mean age of 24 years (10 years after AN onset). All 102 case

The word “desertification” was introduced in 1949 by the French scientist Aubreville in his report “Climats, forêts et désertification de l´Afrique tropicale”. The concept, however, was discussed earlier by European and American scientists in terms of increased sand movements, desiccation, desert and Sahara encroachment and man made deserts. Desertification, at the beginning of last century, mea

In this paper, we study random puncturing of protograph-based spatially coupled low-density parity-check (SC- LDPC) code ensembles. We show that, with respect to iterative decoding threshold, the strength and suitability of an LDPC code ensemble for random puncturing over the binary erasure channel (BEC) is completely determined by a single constant that depends only on the rate and iterative deco

During the first months of 1887, while completing the drafts of his Mitteilungen zur Lehre vom Transfiniten, Georg Cantor maintained a continuous correspondence with Benno Kerry. Their exchange essentially concerned two main topics in the philosophy of mathematics, namely, (a) the concept of natural number and (b) the infinitesimals. Cantor's and Kerry's positions turned out to be irreconcilable,

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

Sedentary passerine birds living in temperate and boreal regions need a high metabolic capacity for thermogenesis to survive winter conditions. As a consequence of the increased thermogenic capacity, basal energetic demands rise at a time when resources and time to acquire them decrease. In a previous study, great tits (Parus major) from two localities in Fennoscandia with contrasting winter condi
