Popular Abstract in Swedish Skador med avskärning av nerver i övre extremiteten drabbar oftast unga personer. Nervskadan medför ett betydande handikapp i form av förlorad känsel och muskelkontroll i armen och/eller handen. Vid en nervskada dör de delar av nervfibrerna (axonerna) som är belägna bortom avskärningen medan nervens stödjeceller och ytterhölje finns kvar. För att återfå funktion måste nA new and simple method for the repair of nerve defects, in which sutures alone are used to guide regeneration between the nerve endings, was developed. Bilateral seven to 17 mm rat sciatic nerve defects were bridged by continuous longitudinal sutures with or without different modifications, by conventional autologous nerve grafts or direct repair under tension as controls. Evaluation was performe

The process of population ageing that has been occurring in Sweden can be expected to continue during the coming decades, the population pyramid will become increasingly rectangular, and possibly even demonstrating a shrinking base. This will lead to increasing challenges in terms of financing pensions, elderly care and healtcare. These problems will continue for at least 30 years with no demograp

Popular Abstract in Swedish Som titeln antyder behandlar avhandlingen titrerande polyelektrolyter, d.v.s. stora molekyler med många syra-basgrupper. Sådana molekyler kan vi finna lite överallt, ja till och med i våra kroppar, som innehåller en mängd olika polyelektrolyter. Deras egenskaper kan variera starkt beroende på omständigheterna och har många biologiska och industriella tillämpningar. Att Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. Sampling is facilitated for the latter two by the use of pivot

This book hopes to offer an insight into the threats facing the vernacular buildings that survive in the Egyptian Western Desert. It offers a guide to those who wish to get involved in rescuing these buildings, those who re-use them and those who care for them. The first part of the book opens with an overview of the problems experienced in places that are only now becoming vulnerable to the rapid

This study is an attempt to increase the understanding of strategic changes at enterprises in Central Eastern Europe. It suggests analysing this transformation as the management of strategic change with a focus on the change processes in which strategic resources are created and deployed. The overall purpose is to develop a strategic change framework to enable the understanding of the transformat

A simple model is presented as an aid in understanding, first, the relative noise performance and, second, the noise reduction achievable by referencing, in different experimental approaches to single shot broadband coherent anti-Stokes Raman scattering (CARS). Qualitative agreement is obtained with previous experimental investigations of CARS noise. The broadband dye laser radiation is described

The Germanic V2 languages differ from English and Italian in not allowing backward binding. In this paper I have tried to account for this cross-linguistic variation in terms of a recent proposal by Chomsky (2008) that A-chains and A-bar chains should be held strictly apart, and that A-movement and A-bar movement sometimes may take place in parallel. With respect to backward binding, I have claime

Popular Abstract in Swedish Många grundläggande processer i naturen involverar transport av energi från ett ställe till ett annat. Ett exempel på detta är fotosyntesen där solljus fångas upp av molekylkomplex, för att sedan transporteras till ett reaktionscenter. I reaktionscentret byggs den laddning upp som sedan används för att framställa växtmassa. För att minimera energiförlusten i den här typAn efficient transfer of energy in molecular systems has proven to be of fundamental importance both in nature and industrial applications. The ability of molecules to work together forming collective excitations, so-called excitons, plays a key role in for example the extraordinary fast energy transfer involved in the first steps of photosynthesis. The characterization of excitonic states in conj
