Results from experiments on laboratory scale fedbatch processes are presented as well as analysis and design of the control system. The main reason for control is to track the drastic growth in feed demand during a cultivation. Variations in the amount and quality of the inocculum makes precalculated dosage schemes of limited value to obtain reproducible cultivation conditions. Two processes have

Drying is an important process in paper manufacturing, where steam heated cylinders are used to dry paper. Control of the moisture content is accomplished by adjusting the steam pressure in the cylinders. This paper presents a nonlinear dynamic model, based on heat and mass balances for steam, cylinder, and paper. It is implemented in the object-oriented modeling language Modelica and is used to e

An illustrated key is presented for the fifteen West Palearctic species and subspecies of the genera Ctenophora, Dictenidia, Phoroctenia and Tanyptera, with a review of their distribution and an overview of the recent literature for these taxa.

Penelope Delta was a writer of books for children in the beginning of the twentieth century in Greece. Delta was active when the national project was at its peak. Delta's own participation in the national project consisted of writing for children in a vernacular language and belonging to a group of intellectuals actively promoting modernization in other aspects than only political and technologica

Popular Abstract in Swedish Fetma, övervikt och allergi är ett problem i många delar av världen och förändringar i tarmens bakterieflora kan vara en av flera orsaker. Människan har tio gånger fler mikroorganismer än mänskliga celler. Flest mikroorganismer finns i tarmen och de brukar gemensamt kallas för tarmfloran. Många bakterier är helt oskadliga och en del är dessutom nödvändiga för att vi tilThe gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. The bacterial flora was mainly studied with molecu

Background: Despite the fact that old people´s technological needs have been payed much attention to in the last decennium, especially old users of information- and communication technology, technology has not found its natural place in research on ageing in modern societies. Purpose: This article examines to what extent social science research exist in the field of ageing and technology and where

Cities divided by violent conflict, such as Mostar, Beirut and Nicosia, have proved remarkably resistant to peacebuilding efforts aimed at reconstruction, reintegration and reconciliation. Such cities tend to freeze the conflict, as it remains divided regardless of a conflict settlement. Contested cities therefore become symbols of the continuities rather than discontinuities between war and peace
