Managing short-term efficiency and long-term development through industrialized construction

There is a strong need for a productive and innovative infrastructure sector because of its monetary value and importance for the development of a sustainable society. An increased level of industrialization is often proposed as a way to improve efficiency and productivity in construction projects. In prior literature on industrialized construction, there are however neither many studies addressin

Spinal Cord Injuries

Spinal cord injury can be classified as traumatic and non-traumatic. The traumatic spinal cord injuries (SCI) are caused by motor vehicle accidents (56 %), falls (14 %), firearm and violence-related (16.6 %) and sports injuries (7 %) [1]. Injuries after falls and minor trauma are more commonly seen in elderly patients as they more often have spondylosis and osteoporosis. Violence is more common in

Beta-glucose 1-phosphate interconverting enzymes in Lactococcus lactis: physiological role and regulation in maltose, trehalose and glucose metabolism

Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. The aim of this study was to investigate the maltose an

k-space Models in MRI Using the Concept of Partitions, Applications with special reference to Overhauser-enhanced techniques

A new model describing the image formation in magnetic resonance imaging (MRI) has been developed. The k-space description of MRI pulse sequences is expanded by introducing new dimensions to describe the phase dispersion due to flow, acceleration, jerk, diffusion and magnetic field inhomogeneities. When the multi-dimensional k-space is combined with a partition model it becomes possible to model t

Development and application of strategies for the analysis of modification patterns in chondroitin and dermatan sulphate

Chondroitin (CS) and dermatan sulphate (DS) are socalled glycosaminoglycans (GAG) that are covalently attached to various type of proteins forming a subgroup within the diverse proteoglycan (PG) family. The PGs studied in this thesis are mostly extracellularly located and include aggrecan, biglycan and decorin. The CS and DS chains both consist of repeating disaccharides of the type (hexuronic aci

The Role of HoxB4 in Hematopoiesis

Popular Abstract in Swedish I kroppen produceras varje dag ca 1 000 000 000 000 nya blodceller för att ersätta celler som förbrukats eller sorterats undan som odugliga. I toppen av hierarkin finns den hematopoietiska stamcellen, eller blodstamcellen, en cell med ett antal unika egenskaper: (i) Förmågan att dela sig och ge upphov till minst en ny blodstamcell (cell med samma egenskaper som modercelHOXB4 is one of 39 members of the homeobox (HOX) family, a family of transcription factors involved in embryonic development. Several HOX transcription factors, including HOXB4, are highly expressed in hematopoietic stem cells (HSCs) but are downregulated upon differentiation towards more mature progeny cells. Enforced expression of HOXB4 dramatically increases the regeneration of murine HSC follo
