Genetic Engineering of Industrial Micro-organisms - Casein hydrolysis by the lactic acid bacteria Lactococcus lactis subsp. cremoris and Lactobacillus rhamnosus and Xylose fermentation by the yeast Saccharomyces cerevisiae

Micro-organisms are used industrially by humans, to improve production, either qualitatively or quantitatively, and to enhance profit or value. In cheese production, the starter bacteria hydrolyse casein degradation products generated by rennet. Some bitter peptides accumulate during cheese ripening, and their degradation would improve the flavour of the cheese. Plasmid pHP003 from the starter st

A comparative study of kinematic and acoustic age-related variability in speech

In this study, we compared age-related lip mo- vement variability with acoustic variability ac- ross repetitions using Functional Data Analysis (FDA). Lip movement and acoustic data of 15- 20 repetitions of a short Swedish phrase from 50 Swedish speakers were collected. Results showed weak to moderate negative correlations for age and variability in lip movements, phrase duration and sound pressur

Renblåsning och rotorkanalform

Regenerativ värmeväxling med rotor har ett varvtalsberoende överföringsflöde med frånluft till tilluft, vilket elimineras med ett renblåsningsflöde. Det är inte självklart att en rotor blir renblåst även om renblåsningsvolymen för en rotorkanal är större än rotorkanalens volym. Syftet med denna arbetsrapport är att komplettera en tidigare arbetsrapport med titeln Ren- blåsning med diffusion TV

On Volume Average Relations in Continuum Mechanics, Part II

This paper continues the analysis of volume average relations that was initiated in [1]. In this paper, as well as in the previous one, results from various investigations, presented in the literature, have been reviewed and extended and they have, in some cases, been more precisely stated and rigorously proven. Some of the results in the present paper are believed to be entirely new. The key obje

Exception Handling in Recipe-Based Batch Control

Exception handling constitutes a large part of the design and implementation effort in batch production, but so far little work has been carried out to specify this area. This paper proposes an internal model approach for unit supervision using Grafchart. It also discusses exception handling at the recipe level.

Om konstkritik. Studier av konstkritik i svensk dagspress 1990-2000

The book is a part of the result of a project, funded by HSFR (The Swedish Council for Research in the Humanities and Social Sciences). In general it comprises the art criticism in the Swedish daily press from 1990-2000. The studies have a common focus on the text of the art criticism, in contrast to older research on art criticism, which uses the text primarily as a source of knowledge about the

Emily Dickinson : A study of the production of an author

Since they were first published in the 1890's Emily Dickinson's (1830-1886) poems have elicited queries regarding the proprieties of editing. This dissertation considers processes through which Dickinson's work has been edited in the twentieth century and how such editorial processes contribute specifically to the production of Emily Dickinson as author. As the project of editing Dickinson's work

The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature

Popular Abstract in Swedish Fotosyntesen är nödvändig för vårt liv på jordklotet. Fotosyntes utförs huvudsakligen av gröna växter och dessutom av vissa bakterier. Dessa organismer absorberar energin i solljuset och omvandlar den till kemisk energi i form av till exempel kolhydrater och fett som vi människor och djur sedan kan förbränna och utvinna energi ifrån. Fotosyntesen utförs av ett flertal pPSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. Another component of PSII which interacts magnetically with Mn4Ca is D2-Ty

Footwear for cold weather conditions

In cold climates all user requirements for footwear (insulation, waterproof, vapour permeability, drying etc.) can’t be met easily due to their conflicting nature. Defining user conditions is important. Cold may be roughly divided into the three ranges (>+5; +5 to 10; < 10 °C). The choice of proper footwear may be based on this approach. It also reduces some of the conflicting user requirements. U
