Even though B-lymphocyte development is one of the best understood models for cell differentiation in the hematopoetic system, recent advances in cell sorting and functional genomics has increased this understanding further. This has suggested that already early lymphoid primed multipotent progenitor cells (LMPPs) express low levels of lymphoid restricted transcripts. The expression of these genes

Small and medium sized enterprises (SMEs) play an important role in all economies today and although their individual environmental impact is often limited, their total impact can be said to be significant due to their sheer number. Environmental management is a way to reduce the impact, but the results obtained by implementing ISO 14001 vary. The point of departure for this dissertation is the hy

The wish to see beyond the horizon of the human biological eye is one of the major driving forces in the development of medical imaging technology. This essay discusses the implications technology has on the ability to see, and consequently know, more about the body. Further, the potential of merging art, rehabilitation engineering and medicine to develop and use images specifically designed to cr

Infestation of skin by the parasitic itch mite Sarcoptes scabiei afflicts 300 million people worldwide and there is a need for novel and efficient therapies. We have previously identified a multigene family of serine proteases comprising multiple catalytically inactive members (scabies mite-inactivated protease paralogs (SMIPPs)), which are secreted into the gut of S. scabiei. SMIPPs are located i

This thesis was motivated by contradictory results from previous studies on reading describing foreign language learners in upper secondary school. Methods based upon ideas by Palinscar & Brown, Cooper, Beck et al, and Krashen were tested on approximately 200 students studying Spanish in the first two years of upper secondary school in Sweden. The methods used are called reciprocal reading, k

A two-echelon distribution inventory system with a central warehouse and a number of retailers is considered. The retailers face stochastic demand. The system is controlled by continuous review installation stock (R,Q) policies with given batch quantities. There are linear holding costs at all locations and linear backorder costs at the retailers. We present a simple technique for approximate opti

The modern synthesis of genetics with evolution slanted our understanding of evolution and of ourselves by rejecting Darwin’s view of animals as participating in their own evolution. Defining evolution in terms of genetics, the modern synthesis indulges excessive individualism and distorted self-images as self-made. At the same time, such gene-centred thought, evoking images of master molecules ma

Abstract in UndeterminedImmobilized bioelements offer additional sensitivity and/or selectivity in analytical techniques, in biotechnological devices, and in different medical applications. Great research interest has recently been focused in all these fields on miniaturization techniques, special attention being accorded to the patterning of biomolecules (e.g. enzymes) on solid surfaces with micr
