Downstream Processing Using Membrane Technology

Popular Abstract in Swedish Membranteknik är en separationsteknik där stora partiklar skiljs av från mindre partiklar m.h.a. ett membranfilter. I min forskning har jag tittat på hur membranfiltrering kan användas inom bioteknikindustrin. Jag har tittat på hur mjölksyra kan renas upp från en lösning av jäst "vetemjölsvälling" samt hur första steget i uppreningen av protein A från en industriellt prMembrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. However, one drawback is that these liquids are often very complex, which is a disadvantage when using membrane technology as it makes the

Asymmetric Information and The Production of Health

Popular Abstract in Swedish Det samlade temat för de sju artiklarna i denna avhandling är att se på hur modern national-ekonomiska teori, som behandlar problem rela-terade till förekomsten av asymmetrisk infor-mation, kan användas för att studera insatser för åstadkomma bättre hälsa. Artiklarna rör dels vård på sjukhus,dels produktionen av läkemedel. För sjukhusen handlar det om hur man via olika The common theme of this thesis is the analysis of asymmetric information when applied to the market for health care production. The thesis consists of six more or less independent papers and an introduction to the thesis were purpose and methodology are stated (part one). Part two is an investigation into the pricing of pharmaceuticals in Sweden. This chapter deals with issues such as cost sharin

Interstitial laser hyperthermia of a rat liver adenocarcinoma

The aim of this study was to compare interstitial laser thermotherapy with excision of a liver tumour. A dimethylhydrazine-induced adenocarcinoma was implanted into the left lateral lobe of the rat liver, and treatment was performed 8 days later. Rats were treated with resection of the tumour-bearing lobe or underwent interstitial laser thermotherapy, which was performed at a steady-state temperat

The Faint Optical Stellar Luminosity Function in the Ursa Minor Dwarf Spheroidal Galaxy

Analyses of their internal stellar kinematics imply that the dwarf spheroidal (dSph) companion galaxies to the Milky Way are among the most dark matter-dominated systems known. Should there be significant dark matter in the form of faint stars in these systems, the stellar luminosity function must be very different from that of a similar metallicity globular cluster, for which there is no evidence

Dimensions of Health among Patients in Mental Health Services

Popular Abstract in Swedish Empiriska studier som fokuserar på subjektivt upplevd hälsa hos patienter i psykiatrin är sällsynta och merparten av de frågeformulär som finns är baserade på en medicinsk grund där objektivt observerbara sjukdomsindikatorer betonas. I studie I och II analyseras och beskrivs uppfattningar av begreppet hälsa hos patienter och sjuksköterskor i psykiatrisk vård med hjälp aEmpirical studies focusing on the subjective experience of health among patients in contact with the mental health services are rare and most questionnaires are based on a medical model that emphasizes objectively observed disease-oriented health indicators. In studies I and II perceptions of the concept of health among patients and nurses in mental health services were explored and described usin

Evidence for soil water control on carbon and water dynamics in European forests during the extremely dry year: 2003

The drought of 2003 was exceptionally severe in many regions of Europe, both in duration and in intensity. In some areas, especially in Germany and France, it was the strongest drought for the last 50 years, lasting for more than 6 months. We used continuous carbon and water flux measurements at 12 European monitoring sites covering various forest ecosystem types and a large climatic range in ord

A Turbo Code Interleaver Design Criterion Based on the Performance of Iterative Decoding

The performance of a turbo code is dependent on two code properties: its distance spectrum and its suitability to be iteratively decoded. Both these properties are influenced by the choice of interleaver used in the turbo encoder. This paper presents an interleaver design criterion that focuses on the performance of iterative decoding, based on the correlation properties of the extrinsic inputs. I

Implants in the abdominal wall of the rat

An experimental model is presented that allows qualitative as well as quantitative studies of the soft tissue response to implant materials used in reconstructive surgery. Plugs of non-alloyed titanium and polymers (Teflon, Delrin) were inserted into the abdominal wall of rats, with a portion of the plug penetrating through the peritoneum into the abdominal cavity. The tissue reaction was evaluate

Phenotype in a Swedish family with X-linked retinitis pigmentosa caused by a novel splice defect in the RPGR gene

PURPOSE: To assess the clinical phenotype in a Swedish family with X- linked retinitis pigmentosa (XLRP) resulting from a novel splice defect in the RPGR gene. METHODS: RPGR mutation analysis was performed in one family with XLRP, and several individuals from the family were examined clinically. RESULTS: The causative mutation in the family was demonstrated to be a single base-pair change at the s

Models of compact simple Kantor triple systems defined on a class of structurable algebras of skew-dimension one

Let $(A,^-):={\cal M}(J)$ be the $2 \times 2$-matrix algebra determined by Jordan algebra $J:=H_3(\mathbb{A})$ of hermitian $3 \times 3$-matrices over a real composition algebra $\mathbb{A}$, where $(A,^-)$ is the standard involution on $A$. We show that the triple systems $B_A(x,\overline{y}^\sim,z), x,y,z\in\mathbb{A}$, are models of simple compact Kantor triple systems satisfying the condition
