Combining the strengths of an advanced mathematical model of human physiology and a thermal manikin is a new paradigm for simulating thermal behaviour of humans. However, the forerunners of such adaptive manikins showed some substantial limitations. This project aimed to determine the opportunities and constraints of the existing thermal manikins when dynamically controlled by a mathematical model
The search for improvement of the physical properties of two very dissimilar polymeric materials is the aim of this doctoral thesis. The high performance properties of polybenzoxazines are tackled via the preparation of novel amino-functional benzoxazine monomers, as well as by the addition of graphene oxide (GO) for the preparation of polybenzoxazine nanocomposites. The synthesis of the amino-fun
To run a Diesel engine in Homogeneous Charge Compression Ignition (HCCI) mode has proved to be a highly promising approach towards reduced engine-out emissions of NOx and particulate matter. A crucial issue when utilizing HCCI is the degree of charge homogeneity that is required to achieve the desired low temperature combustion. A very well mixed charge can be created through the use of traditiona
Popular Abstract in Swedish Kärnmagnetisk resonans (NMR) är en metod som bygger på att många atomkärnor uppför sig som mycket små magneter. Detta i sin tur beror på att kärnan beter sig som en liten roterande laddning. Man säger att kärnan har ett spinn, eller att kärnan är ett spinn. I min avhandling använder jag mig av en fantastisk egenskap hos kärnspinnen. Om man stör systemet kIn the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. The approach also makes it possible to characterize the involved dynamic properties in much greater detail. T
The use of commercial proteases, bromelain and Protex 30L for oil extraction/recovery of polyunsaturated fatty acids (PUFA) from Nile perch and salmon heads was evaluated. Four phases were obtained after hydrolysis, oily phase, emulsion, aqueous phase and sludge. An increase in water content during the hydrolysis resulted in a decrease in oil yield. Maximum oil yield was obtained when hydrolysis w
In this paper, we report experimentally and theoretically a surface photocatalysis reaction of 4-aminothiophenol (PATP) to p,p'-dimercaptoazobenzene (DMAB) on Au, Ag, and Cu colloids. Surface enhanced Raman scattering (SEAS) spectra of PATP on Au and Cu colloids are significantly different from the normal Raman spectrum of PATP powder. Quantum chemical calculations reveal that PATP on Au and Cu co
On the basis of a T = 1 icosahedral capsid model, the capsomer-polyion co-assembly process has been investigated by molecular dynamics simulations using capsomers with different net charge and charge distribution as well as linear, branched, and hyper-branched polyions. The assembly process was characterized in terms of the time-dependent cluster size probabilities, averaged cluster size, encapsul
The effect of applied potential pulses on DNA functionalization (thiolated single stranded DNA) and hybridization processes has been monitored in-situ on gold surfaces using electrochemical quartz crystal microbalance with dissipation (EQCM-D). The applied potentials were chosen with respect to the potential of zero charge (E-pzc) of the gold surfaces: a positive potential to attract the negativel
A bi-enzymatic cascade consisting of a Baeyer-Villiger monooxygenase and an alcohol dehydrogenase (ADH) was designed in a convergent fashion to utilise two molar equivalents of cyclohexanone (CHO) and one equivalent of 1,6-hexanediol as a 'double-smart cosubstrate' to produce epsilon-caprolactone (ECL) with water as sole by-product. The convergent enzymatic cascade reaction reported herein, is per
Palaeomagnetic and geochronological studies on mafic rocks in the Lake Ladoga region in South Russian Karelia provide a new, reliably dated Mesoproterozoic key paleopole for the East European Craton (Baltica). U-Pb dating on baddeleyite gives a crystallisation age of 1452 +/- 12 Ma for one of the studied dolerite dykes. A mean palaeomagnetic pole for the Mesoproterozoic dolerite dykes. Valaam sill
Summary In 1895 a posthumous essay by the Swedish poet and scholar Viktor Rydberg (1828- 1895) was published with the, for many modern Europeans, provoking title Den hvita rasens framtid (“The future of the white race”). In the late 20th century however “the white race” was a commonly used expression, it did not indicate any right-wing sympathies. Rydberg himself was a leftist, a social liberal. C
Phosphorylation of extracellular-signal-regulated kinase 1/2 (p-ERK 1/2) was investigated by immunohistochemistry at 30 min, 1 h, and 48 h after nerve transection in the sciatic nerve of healthy and diabetic [streptozotocin (STZ)-induced diabetes mellitus and BioBreeding (BB; i.e. DR.lyp/lyp or BBDP)] rats. Transection injury increased the intensity of p-ERK 1/2 in nerve stumps at all time points.
Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy i
OBJECTIVES: To characterize the clinical phenotype and to study the course of disease in patients with Alström syndrome, with an emphasis on retinal function assessed with full-field electroretinography (ERG). METHODS: Three age- and sex-matched patients with Alström syndrome were selected from our retinitis pigmentosa register for repeated ophthalmologic examinations that included tests for color
Dyskinesia seen in the off-state, referred as graft-induced dyskinesia (GID), has emerged as a serious complication induced by dopamine (DA) cell transplantation in parkinsonian patients. Although the mechanism underlying the appearance of GID is unknown, in a recent clinical study the partial 5-HT(1A) agonist buspirone was found to markedly reduce GID in three grafted patients, who showed signifi

Rett syndrome (RTT) is a rare neurodevelopmental disorder usually affecting females. It is associated with intellectual and multiple disabilities leading to a high level of dependency in all aspects of daily living including participation in physical activities. This study explored facilitators and barriers to “uptime” (non-sedentary) activities in Danish girls and women with RTT as perceived by p
Background: Seasonal variation in glucose metabolism might be driven by changes in daylight. Melatonin entrains circadian regulation and is directly associated with daylight. The relationship between melatonin receptor 1B gene variants with glycemic traits and type 2 diabetes is well established. We studied if daylight length was associated with glycemic traits and if it modified the relationship
Particulate methane monooxygenase (pMMO) is one of the few enzymes that can activate methane. The metal content of this enzyme has been highly controversial, with suggestions of a dinuclear Fe site or mono-, di-, or trinuclear Cu sites. Crystal structures have shown a mono- or dinuclear Cu site, but the resolution was low and the geometry of the dinuclear site unusual. We have employed quantum ref
