Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for
This study investigates what impact Fairtrade has on labour and human rights development in the Kenyan cut flower industry, by discerning developments and comparing conditions between Fairtrade and non-Fairtrade farms. The developments sustainability and Fairtrade in relation to previous research is also brought up and discussed. The study is mainly based on interviews with people knowledgeable ab
The purpose of this paper is to evaluate international counterterrorism efforts to estimate their costs and potential adverse effects over time. An underlying presumption of the study is that flawed counterterrorism measures to some extent are counterproductive, and building on this idea a comparison is made between the distinguishing features of the 'War on Terror' and an alternative mode
By conceiving identity as endogenously defined and construing other central political concepts according to this assumption, constructivism has proven apt to understand and explain phenomena that eariler were hard to grasp. Constructivist ideas have here been used in order to analyze the events surrounding the Single European Act as a contrast to the more conventional rationalist approach used by
The Big Tech companies, more precisely the five American giants: Google, Apple, Facebook, Amazon and Microsoft, have been performing a massive number of startup acquisitions and strengthening their dominant position in the market. In an economical study about mergers in the pharmaceutical sector the term killer acquisition was firstly adopted to define a transaction in which an incumbent, after ac
This thesis addresses the challenge of transforming car-oriented, mono-functional big-box landscapes into multi-functional, walkable local-centre. It assembles an integrated framework from recent research and translates it into a design approach to be tried in a case study. In contrast to the proposed multi-functional approach, a monocentric urban system concentrates functions and advantages in
Modern cellular radio base stations (RBS) employ beamforming to dynamically steer radio frequency (RF) energy toward active users. This adaptive transmission produces significant angular and temporal variations in the equivalent isotropically radiated power (EIRP). To account for these variations, electromagnetic field (EMF) compliance assessment of RBSs rely on the usage of the EIRP envelope toge

Structure analysis of partially depolymerized methyl cellulose was performed by nanoelectrospray ionization tandem mass spectrometry (nano-ESI-MS/MS) and by matrix-assisted laser desorption/ionization tandem mass spectrometry (MALDI-MS/MS). Dimethylamine (DMA) was used for the first time as a reducing end derivatization reagent for oligosaccharides. This is an attractive reagent since it could be
BACKGROUND Marked changes have occurred in in vitro fertilization (IVF) methodology during the past 25 years but also in characteristics of couples undergoing treatment. METHODS This study was based on 27 386 women undergoing IVF treatment from 1982 to 2006 and giving birth to 31 850 infants. Outcomes of deliveries were studied using Swedish health registers. Comparisons were made with all deliver
AIMS/HYPOTHESIS: Islet autoantibodies are important in diabetes classification and risk assessment, and as endpoints in observational studies. The Diabetes Autoantibody Standardization Program (DASP) aims to improve and standardise measurement of autoantibodies associated with type 1 diabetes. We report results for glutamic acid decarboxylase autoantibodies (GADA) and islet antigen-2 autoantibodie
While scientific community disagrees about similarities and differences between human embryonic stem (hES) cells and human induced pluripotent stem (hiPS) cells, some politicians embrace translational hiPS cell research as a replacement for translational hES cell research. We examine the ethical relevance of the main differences between hES and hiPS cell-based therapies and discuss whether, given
In the adult mammalian brain, neurogenesis from neural stem/progenitor cells continues in two regions: the subgranular zone in the dentate gyrus and the subventricular zone lining the lateral ventricles. The generated neuroblasts migrate to their appropriate location and differentiate to mature granule cells and olfactory bulb interneurons, respectively. Following injury such as stroke, neuroblast
PurposeTo elucidate the temporal relationship between detection of glaucomatous optic disc progression, as assessed by fundus photography, and visual field progression.DesignProspective, randomized, longitudinal trial.ParticipantsThree hundred six study eyes with manifest glaucoma with field loss and 192 fellow eyes without any field defect at the start of the trial, from a total of 249 subjects i
Studies of sphingolipids have become one of the most rapidly advancing fields in the last two decades. These highly diverse lipids have been known to have multiple physiological functions and clinical implications in several diseases, including tumorigenesis, inflammation, atherosclerosis and neural degenerative diseases. Unlike other organs, sphingolipids in the intestinal tract are present not o
In this paper we study the scalability issue in the design of a centralized policy server controlling resources in the future IP-based telecom network generation. The policy servers are in charge of controlling and managing QoS, security and mobility in a centralized way in future IP-based telecom networks. Our study demonstrates that the policy servers can be designed in such a manner that they s
