Popular Abstract in Swedish Växter är en av den största grupperna av organismer på jorden. Den här gruppen av organismer kan syntesisera kolhydrater med solenergi. I växter används en stor del av kolhydraterna till att bilda förnyelsebara polysackarider som sedan används för att bygga upp vedstrukturer. Den mest kända växtpolysackariden är cellulosa som består av långa kedjor av glukos. Den näst mHemicellulose is the second most abundant group of renewable polysaccharides. Mannans can be found as the major hemicellulose in softwood and as storage polysaccharides in a range of plants. In this work, structural and functional characterisations of family 5 and 26 endo-1,4-b-mannanases (b-mannanases) have been performed. These families belong to the large and diverse glycoside hydrolase clan A,

In this article it is argued that Scripture is embedded in the Markan text to such an extent that it cannot be removed without destroying the story. The role Scripture plays in the Gospel (and New Testament) is certainly neither a matter of antithesis nor of fulfillment, but rather of a shared symbolic universe. Analysing Mk 7.1-23 textually, effectually and contextually, this article draws attent

Activities with the aim to assess the effects of ISA on driver behaviour through experimental research were carried out. In order to investigate the regional differences in effects on driver behaviour when driving with ISA field trials were set up in Hungary and Spain. Complementary results were added from the Belgian ISA field trials. To investigate the effects on driver behaviour from different

New methods and products must be developed to reduce our dependency on fossil fuels, to reduce global warming. In this work, methods of extracting and isolating hemi¬celluloses from agricultural and forestry waste streams have been studied. Hemi¬celluloses are biodegradable polymers that can replace fossil-fuel-based products for use in various applications, such as barrier films and hydrogels. Ar

We present a comparative exploratory analysis of two proximity networks of mobile phone users, the Proximates network and the Reality Mining network. Data for both networks were collected from mobile phones carried by two groups of users. Periodic Bluetooth scans were performed to detect the proximity of other mobile phones. The Reality Mining project took place in 2004-2005 at MIT, while Proximat

Popular Abstract in Swedish Partikelfysik och det vetenskapliga arvet Har du gått i en ljus vänlig skog om sommaren när vinden susar bland löven och små djur kilar omkring under gräset och solen skiner på din hud och kittlar din amygdala i det innersta av din hjärna? Har du någonsin reflekterat över naturens oändliga rikedom? Hur kan en värld vara uppbyggd som uppvisar en sådan komplexitet? Vill HERA-B is a high-energy physics experiment at HERA. It is a fixed-target experiment with a forward spectrometer to benefit from the strong boost of beauty hadrons. The main goal of HERA-B is to detect and measure the degree of CP violation in exclusive B-decays, with emphasis on the {em golden} decay, $golden$. A computer simulated study on this decay is presented and the accuracy of the measureme

A reduction of the negative environmental impact caused by urban traffic will to a considerable extent depend on behavioural change. Assuming that attitudes partly guide behaviour, the general aim of the thesis was to increase the understanding of the underlying attitudes of daily travel behaviour and how attitudes related to pro-environmental choice of transport can be promoted. Two questionnaire

Den här rapporten presenterar ett aktionsforskningsprojekt i form av en poesicirkel med sjuksköterskor som arbetar med svårt sjuka och döende människor. Med hjälp av dikten så bearbetar de sina existentiella tankar och upplevelser. Poesin hjälper på så sätt sjuksköterskorna att ge känslorna ett språk. I den aktionsinriktade processen ger sjuksköterskorna uttryck för att poesin hjälper dem att få i

Robust stability of linear systems in presence of bounded uncertain time-varying time delays is studied. The time delay robustness problem is treated in the Integral Quadratic Constraint framework. The stability criterion is formulated as a frequency dependent linear matrix inequality, or equivalently as a Semi-Definite Program (SPD). Therefore, the criterion can be checked efficiently by using va

The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. The STM results have

Popular Abstract in Swedish Infektioner i urinvägar, tarm och luftvägar orsakas av bakterier som speciellt anpassats till respektive vävnad. Infektionen börjar med att bakterien binder till slemhinneytan, och därmed sätter igång inflammation och försvar. Urinvägsinfektioner (UVI) är en värdefull modell för att förstå de molekylära detaljerna som avgör balansen mellan värd och bakterie. UVI orsakaBacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. Patients with recurrent UTI were first subjected to deli
