- Dalton is a powerful general-purpose program system for the study of molecular electronic structure at the Hartree-Fock, Kohn-Sham, multiconfigurational self-consistent-field, MOller-Plesset, configuration-interaction, and coupled-cluster levels of theory. Apart from the total energy, a wide variety of molecular properties may be calculated using these electronic-structure models. Molecular gradients and Hessians are available for geometry optimizations, molecular dynamics, and vibrational studies, whereas magnetic resonance and optical activity can be studied in a gauge-origin-invariant manner. Frequency-dependent molecular properties can be calculated using linear, quadratic, and cubic response theory. A large number of singlet and triplet perturbation operators are available for the study of one-, two-, and three-photon processes. Environmental effects may be included using various dielectric-medium and quantum-mechanics/molecular-mechanics models. Large molecules may be studied using linear-scaling and massively parallel algorithms. Dalton is distributed at no cost from for a number of UNIX platforms.

Perceptions of Information and Communication Technology as Support for Family Members of Persons With Heart Failure : Qualitative Study
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Background: Heart failure (HF) affects not only the person diagnosed with the syndrome but also family members, who often have the role of informal carers. The needs of these carers are not always met, and information and communications technology (ICT) could have the potential to support them in their everyday life. However, knowledge is lacking about how family members perceive ICT and see opportunities for this technology to support them.Objective: The aim of this study was to explore the perceptions of ICT solutions as supportive aids among family members of persons with HF.Methods: A qualitative design was applied. A total of 8 focus groups, comprising 23 family members of persons affected by HF, were conducted between March 2015 and January 2017. Participants were recruited from 1 hospital in Sweden. A purposeful sampling strategy was used to find family members of persons with symptomatic HF from diverse backgrounds. Data were analyzed using qualitative content analysis.Results: The analysis revealed 4 categories and 9 subcategories. The first category, about how ICT could provide relevant support, included descriptions of how ICT could be used for communication with health care personnel, for information and communication retrieval, plus opportunities to interact with persons in similar life situations and to share support with peers and extended family. The second category, about how ICT could provide access, entailed how ICT could offer solutions not bound by time or place and how it could be both timely and adaptable to different life situations. ICT could also provide an arena for family members to which they might not otherwise have had access. The third category concerned how ICT could be too impersonal and how it could entail limited personal interaction and individualization, which could lead to concerns about usability. It was emphasized that ICT could not replace physical meetings. The fourth category considered how ICT could be out of scope, reflecting the fact that some family members were generally uninterested in ICT and had difficulties envisioning how it could be used for support. It was also discussed as more of a solution for the future.Conclusions: Family members described multiple uses for ICT and agreed that ICT could provide access to relevant sources of information from which family members could potentially exchange support. ICT was also considered to have its limitations and was out of scope for some but with expected use in the future. Even though some family members seemed hesitant about ICT solutions in general, this might not mean they are unreceptive to suggestions about their usage in, for example, health care. Thus, a variety of factors should be considered to facilitate future implementations of ICT tools in clinical practice.

- Fibroblasts are central in wound healing by expressing important mediators and producing and remodelling extracellular matrix (ECM) components. This study aimed at elucidating possible mechanisms of action of the ECM protein amelogenin on normal human dermal fibroblasts (NHDF). Amelogenin at 100 and 1000 μg/ml increased binding of NHDF via several integrins, including αvβ3, αvβ5 and α5β1. Further, both surface interaction and cellular uptake of amelogenin by NHDF was observed using scanning and transmission electron microscopy. Gene microarray studies showed >8-fold up or down-regulation of genes, of which most are involved in cellular growth, migration and differentiation. The effect of amelogenin was exemplified by increased proliferation over 7 days. In conclusion, the beneficial effects of amelogenin on wound healing are possibly conducted by stimulating fibroblast signalling, proliferation and migration via integrin interactions. It is hypothesized that amelogenin stimulates wound healing by providing connective tissue cells with a temporary extracellular matrix.

- Abstract: Amelogenins are extracellular matrix proteins used for the topical treatment of chronically inflamed tissues. The influence of amelogenins on human monocyte-derived macrophages was studied by measuring the concentrations of cytokines in culture supernatants. The interactions of cells and protein aggregates were visualised by transmission electron microscopy. The amelogenin treatment of macrophages increased several pro- and anti-inflammatory cytokines, including alternative macrophage activation marker AMAC-1 (p < 0.001) and vascular endothelial growth factor (VEGF; p < 0.001). The levels were independent of cytochalasin B, although amelogenin aggregates were ingested by macrophages. Amelogenin effect was compared with that of tyrosine-rich amelogenin peptide, which apart from augmented VEGF levels (p < 0.05), had no significant influence on the other cytokines analysed. In conclusion, amelogenins increased the macrophage release of key cell mediators involved in tissue repair. The effect was independent of phagocytosis, implying a receptor-mediated signal. The markedly increased levels of AMAC-1 suggest that amelogenins promote a reparative macrophage phenotype.

- Introduction: Angiogenesis is crucial for wound healing but is often impaired in chronic wounds. The process is dependent on the interaction of endothelial cells and the extracellular matrix (ECM), which is mediated by cell membrane integrins. Amelogenin is an extracellular matrix protein that has been reported to promote formation of granulation tissue and repair of chronic venous leg ulcers and elevate the pro-angiogenic vascular endothelial growth factor in dermal fibroblasts.1-3 This study investigated the effect of amelogenin on angiogenesis in an ex vivo sprouting assay and related the findings to the cell surface integrin expression. Methods: Chick aortic arch assay: Transverse sections of the aortic arch of 13-day-old chick embryos were attached and sealed with Matrigel to the bottom of a 48-well plate. Amelogenin was added (0.01 mg/ml, 0.1 mg/ml and 1 mg/ml) in serum-free endothelial basal growth medium. Porcine serum albumin was used as control for unspecific protein effects. The plates were incubated at 37°C and sprouting was assessed at 24 h and 48 h by microscopy and scored from 0 to 6 (arbitrary units) by a blinded observer. Integrin assay: Human dermal microvascular endothelial cells (Promocell) were seeded in complete cell growth medium alone or supplemented with 0.1 mg/ml, 1 mg/ml amelogenin or 20 µg/ml fibronectin. After 24 h incubation in 37°C, cells were gently harvested with the non-enzymatic buffer (EDTA/PBS). Upregulated integrins/subunits were detected by an Integrin-Mediated Cell Adhesion Array (Chemicon), where cells expressing specific integrins (α1, α2, α3, α4, α5, αv, β1, β2, β3, β4, β6, αvβ3, αvβ5 and α5b1) are captured by surface immobilized antibodies. Results and Discussion: Amelogenin at 0.1 mg/ml significantly (p = 0.001) increased micro-vessel outgrowth by 76 % from the explants compared with control explants after 48 h of incubation. No significant sprouting was observed with the non-specific protein control porcine serum albumin or medium only. The preliminary data from the integrin assay show that amelogenin at 0.1 mg/ml also displays a broad up-regulation of several integrins/subunits. This result is comparable to the positive control, fibronectin, an ECM protein involved in all phases of tissue repair. Taken together, the present observations suggest that the angiogenic effects might be explained by the cell binding properties of amelogenin. Conclusions: Amelogenin stimulated micro-vessel outgrowth in the chick aortic arch assay possibly through up-regulation of several integrins and subunits important for cell interaction with the ECM. The pro-angiogenic property may contribute to the beneficial effects reported after treatment of chronic ulcers with the novel ECM therapy containing amelogenin.

In Vitro Effect of Amelogenin on Selected Cell Mediators from Human Monocytes

Konferensbidrag (refereegranskat)abstract
- Introduction: Inflammation is an integral part of the normal wound healing response. Besides clearing the wound of invading microbes and debris, inflammatory cells are believed to be crucial coordinators of the repair process, acting both as phagocytes and as a major source of growth factors and other signals [1]. In non-healing skin ulcers the repair process is stuck in the inflammation phase [2]. Excessive inflammation can reflect an imbalance in the transformation of phenotype between the classically activated, inflammatory macrophage and the alternatively activated macrophage involved in immunosuppression and tissue repair [3]. Amelogenin is a hydrophobic extracellular matrix protein that under physiological conditions will self assemble into nanospheres which in turn may form larger aggregates. Treatment with amelogenin has shown enhanced skin wound healing in an in vivo study in rabbits [4]. In addition, amelogenin has been proposed to have anti-inflammatory properties by attenuation of lipopolysaccharide (LPS)- and peptidoglucan-induced production of selected pro-inflammatory cytokines by human blood cells [5]. The present study was initiated to determine the effects of amelogenin on human monocyte secretion of factors which modulate both inflammation and tissue repair. Materials and Methods: Lyophilized amelogenin from Biora AB (Malmö, Sweden) was dissolved in 17 mM acetic acid. Human monocytes were obtained from six healthy blood donors by isolation using the separation gradient PercollTM in two steps according to Pertoft et al. [6]. The isolated monocytes were cultured for 24 h at 37ºC with 5% CO2 and 95% humidity. Thereafter the supernatants and non-adherent cells were removed. Fresh medium (RPMI, 5% foetal bovine serum, antibiotics) containing amelogenin, 0, 0.01, 0.1 and 1.0 mg/ml, and with or without addition of LPS, was added to the wells in triplicates. The plates were again incubated for 24 h. The supernatants were analyzed with commercial human ELISA assays for tumour necrosis factor- (TNF-), interleukin-10 (IL-10), macrophage inflammatory protein-1 (MIP-1), monocyte chemoattractant protein-1 (MCP-1), vascular endothelial growth factor (VEGF), and insulin like growth factor-1 (IGF-1). Results: Amelogenin treatment markedly altered the expression of factors by human monocytes. Amelogenin significantly reduced LPS-induced TNF- secretion, whereas the IL-10 expression was increased. Monocyte secretion of the two inflammatory chemokines MIP-1 and MCP-1 (Figure; mean ± SEM, n=6) was also affected by amelogenin treatment. Furthermore, amelogenin significantly increased monocyte secretion of VEGF (Figure; mean ± SEM, n=6) and IGF-1, although to a lesser extent, after 24 h culture. Conclusions: The amelogenin effects correlate to protein concentration, however not in a dose dependent manner, but instead the cell responses may reflect a concentration related difference in self assembly of the amelogenin protein. The observed changes in cytokine and chemokine expression are markedly affected by simultaneous LPS-induced inflammation activation, revealing possible anti-inflammatory properties of the amelogenin protein. In addition, the several-fold increase in VEGF-levels by monocytes provides a possible mechanism for the observed pro-angiogenic effect in vivo [4]. These in vitro results indicate that the extracellular matrix protein amelogenin by virtue of its interaction with human monocytes may modulate inflammation and tissue repair.

Tidskriftsartikel (refereegranskat)abstract
- This article discusses the so-called verb-oriented method and its role in the research project Gender and Work in early modern Sweden (GaW), which is based at Uppsala University. It provides a presentation of the GaW-database, which has been designed to allow analysis according to the verb-method. Finally, the article points out that this method can be combined with a number of different theoretical approaches as long as the focus is on practices. It is therefore compatible with the approaches of e.g., Judith Butler, Michel de Certeau, and Amartya Sen. Work is defined as "time-use with the purpose of making a living" and the article discusses why data on time-use, or actual work activities, are better suited for research into early modern Swedish working life than other types of data. It shows that activities are usually described in the sources by verb-phrases, and explains how and from what sources verb-phrases are collected and analyzed within the project. In order to allow for generalizations the verb-method presupposes large amounts of data. This is the rationale for the GaW-database, which at present includes around 5000 verb-phrases and 75000 data posts.

Västerås slott : Slott och borgar
- 2000
-
Rapport (populärvet., debatt m.m.)abstract
- En majoritet av dagens byggnadsuppgifter gäller att hantera det redan byggda. När vi står inför situationen att restaurera en befintlig byggnad är det viktigt att förstå olika tidsperioders stilideal liksom byggnadsteknik och material. Först då kan vi göra en väl avvägd analys, som tar tillvara och utvecklar de kvaliteter som byggnaderna själva besitter. Därför är utbildningen upplagd som ett växelspel mellan föreläsningar, seminarier, exkursioner och en för året vald studieuppgift.Slott och borgar har varit läsårets tema. Vi har valt att arbeta med Västerås och Örebro slott - två ganska bortglömda Vasaslott som är väl värda att lyfta fram. Särskilt har vi studerat de senaste 300 årens förändringar, som inte tidigare ägnats lika stora forskarmöda som medelitden och Vasatiden. I dessa två exempel finns en provkarta på estetiska, praktiska och tekniska ingrepp från Carl Hårlemans tid och fram till idag.Studierna har således omfattat både gestaltning, funktion och byggnadsteknik. Avsikten är att visa på kvaliteter i de omvandlingar och restaureringar som skett, men också att peka på problem och analysera olika möjligheter inför framtiden. Arbetet har skett i samarbete med Statens fastighetsverk och är tänkt att utgöra ett underlag till vårdprogram och framtida restaureringsinsatser.

Recoil-induced ultrafast molecular rotation probed by dynamical rotational Doppler effect
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Observing and controlling molecular motion, and in particular rotation,is a fundamental topic in physics and chemistry. In order toinitiate ultrafast rotation, one needs a way to transfer a large angularmomentum to the molecule. As a showcase, this was performedby hard x-ray C1s ionization of carbon monoxide, accompanied byspinning-up the molecule via the recoil “kick” of the emitted fast photoelectron.To visualize this molecular motion, we use the dynamicalrotational Doppler effect and an X-ray “pump-probe” device offeredby nature itself: the recoil-induced ultrafast rotation is probed by subsequentAuger electron emission. The time information in our experimentorigins from the natural delay between the C1s photoionizationinitiating the rotation and the ejection of the Auger electron. From amore general point of view, time-resolved measurements can be performedin two ways: either to vary the "delay" time as in conventionaltime-resolved pump-probe spectroscopy and to use the dynamicsgiven by the system, or to keep constant "delay" time and to manipulatethe dynamics. Since in our experiment we cannot change the delaytime given by the core-hole lifetime $\tau$, we use the second optionand control the rotational speed by changing the kinetic energy of thephotoelectron. The recoil-induced rotational dynamics controlled insuch a way is observed as a photon-energy dependent asymmetryof the Auger lineshape, in full agreement with theory. This asymmetryis explained by a significant change of the molecular orientationduring the core-hole lifetime, which is comparable with the rotationalperiod.

Tidskriftsartikel (refereegranskat)abstract
- Complex equilibria and phase transformations involving diffusion can now be calculated quickly and efficiently. Detailed examples are given for cases which involve varying degrees of non-equilibrium and therefore time-dependence. Despite very good agreement between such calculations and experimental results, many potential end-users are still not convinced that such techniques could be usefully applied to their own specific problems. Friendly graphic interface versions of calculating software are now generally available, so the authors conclude that the most likely source of the reluctance to use such tools lies in the formulation of relevant questions and the interpretation of the results. Although the potential impact of such tools was foreseen many years ago [M. Hillert, Calculation of phase equilibria, in: Conference on Phase Transformations, 1968], few changes in the relevant teaching curricula have taken into account the availability and power of such techniques. This paper has therefore been designed not only as a collection of interesting problems, but also highlights the critical steps needed to achieve a solution. Each example includes a presentation of the "real" problem, any simplifications that are needed for its solution, the adopted thermodynamic formulation, and a critical evaluation of the results. The availability of such examples should facilitate changes in subject matter that will both make it easier for the next generation of students to use these tools, and at the same time reduce the time and effort currently needed to solve such problems by less efficient methods. The first set of detailed examples includes the deoxidation of steel by aluminum; heat balance calculations associated with ladle additions to steel; the determination of conditions that avoid undesirable inclusions; the role of methane in sintering atmospheres; interface control during the physical vapour deposition of cemented carbide; oxidation of gamma-TiAl materials; and simulation of the thermolysis of metallorganic precursors for Si-C-N ceramics and interface reaction of yttrium silicates with SiC-coated C/C-SiC composites for heat shield applications. A second set of examples, more dependent on competitive nucleation and growth, includes segregation and carburization in multicomponent steels and features a series of sophisticated simulatons using DICTRA software. Interfacial and strain energies become increasingly important in defining phase nucleation and morphology in such problems, but relatively little information is available compared to free energy and diffusion databases. The final section therefore demonstrates how computational thermodynamics, semi-empirical atomistic approaches and first-principles calculations are being used to aid filling this gap in our knowledge.

Tidskriftsartikel (refereegranskat)abstract
- Background Neonatal seizures have been associated with increased mortality and impaired neurodevelopment and, knowledge about risk factors may be useful for prevention. Clear associations have been established between labor-related risk factors and seizures in asphyxiated neonates. However, there is limited information about why some vigorous term-born infants experience seizures. Objectives Our aim was to assess antepartum and intrapartum risk factors for seizures in vigorous term-born neonates. Methods This was a national cohort study of singleton infants born at term in Sweden from 2009-2015. Vigorous was defined as an Apgar score of at least 7 at 5 and 10 minutes. Data on the mothers and infants were obtained from the Swedish Medical Birth Register and the Swedish Neonatal Quality Register. A diagnosis of neonatal seizures was the main outcome measure and the exposures were pregnancy and labor variables. Logistic regression analysis was used and the results are expressed as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results The incidence of neonatal seizures was 0.81/1,000 for 656 088 births. Seizures were strongly associated with obstetric emergencies (aOR 4.0, 95% CI 2.2-7.4), intrapartum fever and/or chorioamnionitis (aOR 3.4, 95% CI 2.1-5.3), and intrapartum fetal distress (aOR 3.0, 95% CI 2.4-3.7). Other associated intrapartum factors were: labor dystocia, occiput posterior position, operative vaginal delivery, and Cesarean delivery. Some maternal factors more than doubled the risk: a body mass of more than 40 (aOR 2.6, 95% CI 1.4-4.8), hypertensive disorders (aOR 2.3, 95% CI 1.7-3.1) and diabetes mellitus (aOR 2.6, 95% CI 1.7-4.1). Conclusion A number of intrapartum factors were associated with an increased risk of seizures in vigorous term-born neonates. Obstetric emergencies, intrapartum fever and/or chorioamnionitis and fetal distress were the strongest associated risks. The presence of such factors, despite a reassuring Apgar score could prompt close surveillance.

En patriotisk drömvärld : Musik, nationalism och genus under det långa 1800-talet
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The subject of this thesis is Scandinavian nationalism from the late 18th century to ca 1920. The focus lies on that particular aspect of nationalism that was at the same time the most mundane and the most enigmatic: the ever-present depicting of the nation in words, pictures and music, which in effect created a parallel universe, a patriotic dreamland. This creation was highly gendered, and the media in which it flourished most abundantly was the patriotic song. The study therefore uses song texts as its primary source material and builds upon the theoretical foundations laid by, e.g., Joan Scott and Michael Billig.Geographically, the investigation centers on Sweden, using Norway and Swedish-speaking Finland as objects of comparison. The main producers of the lyrics and their intended target groups are identified, and an in-depth analysis of a large corpus of songs is made.The main conclusion is that the patriotic songs, in spite of spreading to an ever increasing proportion of the population, were not an expression of the ‘voice of the people’ or even that of the bourgeoisie as a whole. The texts were chiefly written by male academics, and from their formative years during the Napoleonic wars the songs preserved an obsession with a warlike unmarried manhood. Only in the last decades of the period were civilian virtues and national womanhood slightly more emphasized. It is suggested that the songs, apart from being an expression of what Billig has termed ‘banal nationalism,’ also functioned as a bastion of a ‘banal androcentrism.’The thesis shows that the patriotic dreamland of the patriotic songs was designed in a way that promoted the interests of its producers and reproducers. The seemingly semi-autonomous quality of the discourse is also discussed, employing meme theory as used by, e.g., Daniel Dennett.

Som folk är mest : Könsideal i svenska kontaktannonser 1890–1980

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis investigates 5,000 descriptions of men and women in search for a life partner of the opposite sex through classifieds 1890-1980. The advertisers’ descriptions of who they are and what they want sketches a picture of the expectations everyday people have had on how men and women should be over almost a hundred years. Previous accounts of 20th century gender relations are based on governmental and political materials.The bipartite structure of the personals advertisements is used methodologically to differentiate between the so-called “ego-descriptions” and the “alter-descriptions” - what the advertiser had to offer and what the advertiser wanted. Men's descriptions of themselves – ego descriptions – is compared to women's descriptions of the man – alter description –, and women’s descriptions of themselves – ego-description – is compared to men’s descriptions of women – alter description. Six categories were created to capture the content of the personal advertisements: 1) Breadwinner qualifications 2) Parenting qualifications 3) Homemaker qualifications 4) Bodily aspects 5) Leisure 6) Personal interests and qualifications.This study shows that men and women increasingly are described on the grounds of similar qualifications, and that both men and women are increasingly depicted with characteristics that earlier was coded as female. It also shows that children and the family became more important. Stability and security were highly appreciated in the beginning of the period, but gave way to values as mobility and opportunity in the late 1900’s. Both women and men shift from favouring material conditions to an increased focus on feelings and thoughts, and in the end of the period the life partner relationship was more about emotional closeness and the company of a like-minded individual.However, despite these more general results, it is clear that neither the images of the man nor the images woman was unambiguous, and that men and women for most of the time didn't share the same ideals. When thousands of men and women describe their dreams and needs based on the lives they live, unlike government surveys, for example, a multitude of images of the nineteenth century man and woman appear.

Tidskriftsartikel (refereegranskat)abstract
- The tyrosyl radical in galactose oxidase is covalently cross-linked to a neighboring cysteine residue through a thioether bond. The role of this sulfur cross-link has been discussed ever since the crystal structure of the enzyme was solved. In the present work, the ab initio multiconfigurational linear response method is applied to calculate the g-tensor of unsubstituted and thioether substituted phenoxyl radicals. In contrast to some previous interpretations, but in agreement with recent EPR measurements, we find that the sulfur substitution induces only minor shifts in the g-tensor components. The spin distribution retains the odd-alternant pattern of the unsubstituted radical and only a small amount of spin is localized to the sulfur center.

- The electron paramagnetic resonance (EPR) g and N-14 hyperfine coupling (A) tensors of a nitroxide spin label are calculated with density-functional theory (DFT). The influence on the spin label from nearby amino acids in the extracellular part of tissue factor (sTF) and activated factor VII (FVIIa) protein complex is investigated. For that purpose, the nitroxide unit and six surrounding amino acids within 5 Angstrom are selected on the basis of a molecular mechanics structure of the protein complex. The effects of the surroundings on the EPR parameters of the spin label can be divided into indirect effects caused by the induced structure changes of the spin label and direct effects. The structural changes are larger in the present case. The experimentally measurable hyperfine tensor component perpendicular to the molecular plane of the spin label, A(zz), as well as the g tensor component along the NO direction, g,,, are significant probes of the intramolecular structure of the spin label. This indicates the possibility of relating EPR properties to the geometric structure of radical sites. The direct environmental effects on the g tensor from the surrounding amino acids mainly affect the second-order spin-orbit/orbital Zeeman cross-term contributions from the spin label itself. The direct effects originating elsewhere in the model are small. Neither the g nor A tensors display additivity of the effects of individual amino acids on the final observable. The results underline the feasibility of DFT calculations of the EPR parameters in large molecular systems, such as spin labels and other radicals in proteins.

Hydrogen bonding to tyrosyl radical analyzed by ab initio g-tensor calculations

Tidskriftsartikel (refereegranskat)abstract
- Hydrogen bonding to the tyrosyl radical in ribonucleotide reductase (RNR) has been simulated by a complex between the phenoxyl radical and a water molecule. Multiconfigurational self-consistent field linear response theory was used to calculate the g-tensor of the isolated phenoxyl radical and of the phenoxyl-water model. The relevance of the model was motivated by the fact that spin density distributions and electron paramagnetic resonance (EPR) spectra of the phenoxyl and tyrosyl radicals are very similar. The calculated g-tensor anisotropy of the phenoxyl radical was comparable with experimental findings for tyrosyl in those RNRs where the H-bond is absent: g(x) = 2.0087(2.0087), g(y) = 2.0050(2.0042), and g(z) = 2.0025(2.0020), where the tyrosyl radical EPR data from Escherichia coli RNR are given in parentheses. The hydrogen bonding models reproduced a shift toward a lower g(x) value that was observed experimentally for mouse and herpes simplex virus RNR where the H-bond was detected by electron-nuclear double resonance after deuterium exchange. This decrease could be traced to lower angular momentum and spin-orbit coupling matrix elements between the ground B-2(1) and the first excited B-2(2) states (oxygen lone-pair n to pi(SOMO) excitation) upon hydrogen bonding in a linear configuration. The g(x) value was further decreased by hydrogen bonding in bent configurations due to a blue shift of this excitation.

MCSCF and DFT calculations of EPR parameters of sulfur centered radicals
- 2000

Tidskriftsartikel (refereegranskat)abstract
- The EPR parameters of sulfur centered radicals are different depending on the radical structure, charge and solvent. That is, the g- and A-tensor components provide significant patterns which may distinguish sulfur radical structures from each other. In the present work, these EPR parameters were calculated for monosulfide radicals (RS'), disulfide radicals (RSS.), radical cations ((RSSR+)-S-.) and anions ((RSSR-)-S-.), with R = CH3, using the MCSCF linear response and DFT/B3LYP methods. Results were in agreement with experimental data for the cases when well-resolved EPR spectra are available. Especially, the assignment of the disulfide anion in ribonucleotide reductase was confirmed. The results indicate that investigations with the present computational methods on refined structures and solvent modeling may provide interpretations of experimental data on unassigned radical species.

Tidskriftsartikel (refereegranskat)abstract
- Linear response theory has been applied for calculations of g-tensors of organic radicals in order to test the range of validity of restricted Hartree-Fock reference states. The g-values were calculated for the benzene cation (C6H6+), the benzene anion (C6H6-), hydropyrazine (C4H5N2), the dihydropyrazine cation (C4H6N2+), the aniline radical (C6H5NH), the p-benzoquinone anion (C6H4O2-), phenoxyl (C6H5O), the nitrobenzene anion (C6H5NO2-), and the nitropyridine anion (C5H4N2O2-). Influence of variations of structural parameters on the g-tensor components were investigated. Calculated g-values were in excellent agreement with experiment for six out of nine radicals. Two radicals - the p-benzoquinone anion and aniline radical - showed minor discrepancies, while the g-tensor of the phenoxyl radical was incorrect. The problem with the phenoxyl radical was traced to a complex electronic structure and optical spectrum. Results consistent with experiment could in that case only be obtained with electron correlated calculations.

Tidskriftsartikel (refereegranskat)abstract
- Electronic g-factors for ESR spectra of a number of diatomic molecules with a ground X3Σ- state and their electronic spin-rotational coupling constants have been calculated by a linear response method. General expressions are used for the second order correction to the electronic g-factor which account for spin-orbit coupling induced admixtures from all excited triplet states to the ground state orbital magnetism. First order corrections - the spin-Zeeman kinetic energy contribution and the one-electron spin-Zeeman gauge contribution - to the g-factor are also accounted for. Calculated g-factors and spin-rotational coupling constants are in a good agreement with available experimental data. In particular, the positive, anomalous, sign of the spin-rotational coupling constant of the PF radical is reproduced.

- Internet-delivered cognitive behavioral therapy (ICBT) is recommended as an efficient treatment alternative for depression in primary care. However, only few previous studies have been conducted at primary care centers (PCCs). We evaluated long-term effects of ICBT treatment for depression compared to treatment as usual (TAU) in primary care settings.Randomized controlled trial.Patients were enrolled at16 PCCs in south-west Sweden.Patients attending PCCs and diagnosed with depression (n=90).Patients were assessed by a primary care psychologist/psychotherapist and randomized to ICBT or TAU. The ICBT included an ICBT program consisting of seven modules and weekly therapist e-mail or telephone support during the 3-month treatment period.Questionnaires on depressive symptoms (BDI-II), quality of life (EQ-5D) and psychological distress (GHQ-12) were administered at baseline, with follow-ups at 3, 6 and 12 months. Antidepressants and sedatives use, sick leave and PCC contacts were registered.Intra-individual change in depressive symptoms did not differ between the ICBT group and the TAU group during the treatment period or across the follow-up periods. At 3-month follow-up, significantly fewer patients in ICBT were on antidepressants. However, the difference leveled out at later follow-ups. There were no differences between the groups concerning psychological distress, sick leave or quality of life, except for a larger improvement in quality of life in the TAU group during the 0- to 6-month period.ICBT with weekly minimal therapist support in primary care can be equally effective as TAU among depressed patients also over a 12-month period.The trial was registered in the Swedish Registry, researchweb.org, ID number 30511.

Women with Premenstrual Dysphoria Lack the Seemingly Normal Premenstrual Right-Sided Relative Dominance of 5-HTP-Derived Serotonergic Activity in the Dorsolateral Prefrontal Cortices - A Possible Cause of Disabling Mood Symptoms.

Ingår i: PloS one. - : Public Library of Science (PLoS). - 1932-6203. ; 11:9

Tidskriftsartikel (refereegranskat)abstract
- To investigate potential quantitative and qualitative differences in brain serotonergic activity between women with Premenstrual Dysphoria (PMD) and asymptomatic controls.Serotonin-augmenting drugs alleviate premenstrual mood symptoms in the majority of women with PMD while serotonin-depleting diets worsen PMD symptoms, both indicating intrinsic differences in brain serotonergic activity in women with PMD compared to asymptomatic women.Positron-emission tomography with the immediate precursor of serotonin, 5-hydroxytryptophan (5-HTP), radiolabelled by 11C in the beta-3 position, was performed in the follicular and luteal phases for 12 women with PMD and 8 control women. Brain radioactivity-a proxy for serotonin precursor uptake and synthesis-was measured in 9 regions of interest (ROIs): the right and left sides of the medial prefrontal cortex, dorsolateral prefrontal cortex, putamen and caudate nucleus, and the single "whole brain".There were no significant quantitative differences in brain 5-HTP-derived activity between the groups in either of the menstrual phases for any of the 9 ROIs. However, multivariate analysis revealed a significant quantitative and qualitative difference between the groups. Asymptomatic control women showed a premenstrual right sided relative increase in dorsolateral prefrontal cortex 5-HTP derived activity, whereas PMD women displayed the opposite (p = 0.0001). Menstrual phase changes in this asymmetry (premenstrual-follicular) correlated with changes in self ratings of 'irritability' for the entire group (rs = -0.595, p = 0.006). The PMD group showed a strong inverse correlation between phase changes (premenstrual-follicular) in plasma levels of estradiol and phase changes in the laterality (dx/sin) of radiotracer activity in the dorsolateral prefrontal ROI (rs = -0.635; 0.027). The control group showed no such correlation.Absence of increased premenstrual right-sided relative 5-HTP-derived activity of the dorsolateral prefrontal cortices was found to strongly correlate to premenstrual irritability. A causal relationship here seems plausible, and the findings give further support to an underlying frontal brain disturbance in hormonally influenced serotonergic activity in women with PMD. Because of the small number of subjects in the study, these results should be considered preliminary, requiring verification in larger studies.

Tidskriftsartikel (refereegranskat)abstract
- While gender relations in the post-1800 labour market have been subject to much scholarly scrutiny, less is known about how women and men supported themselves in the early modern period. This article discusses the reasons for this lacuna and explores various approaches that could be used to increase knowledge in the field. It describes the verb-oriented method, used by the Gender and Work project at Uppsala University and inspired by the work of Sheilagh Ogilvie. Understanding ‘work’ as ‘use of time with the goal of making a living’, the method consists in systematic collection of verb phrases such as ‘to fish herring’, ‘to sell clothes’, etc. The article also presents the database GaW, which is designed so as to make possible systematic analysis of large sets of verb phrases.

RAPPORT GEODATARÅDETS HANDLINGSPLAN 2020 : Aktivitet – 4i, Långsiktig kompetensförsörjning inom geodataområdet
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I den nationella geodatastrategin som gäller för åren 2016–2020 återfinns målet ”Samverkan är välutvecklad” (mål nummer 4). Inom ramen för detta mål ingår en aktivitet (4i) som syftar till att säkerställa den långsiktiga kompetensförsörjningen inom geodataområdet. För att arbeta med frågan tillsattes en arbetsgrupp med representanter från Lantmäteriet och ett antal lärosäten. I denna rapport redovisas resultatet av den tillsatta arbetsgruppens undersökningar. Arbetet är i första hand inriktat på att hitta en väg framåt som kan leda till att kompetensen inom geodataområdet långsiktigt kan säkerställas och utvecklas. I uppdraget ingår även en internationell utblick. Denna har avgränsats till att avse våra nordiska grannländer, dvs. Norge, Finland, Danmark samt Nederländerna och Österrike. Geodataområdet har avgränsats till att omfatta följande områden:Geodesi Tekniska aspekter av geografiska informationssystem (GIS) och geografisk informationsteknologi (GIT)FjärranalysFotogrammetri inklusive laserskanningTekniskt lantmäteriMånga av slutsatserna från äldre rapporter och utredningar gäller fortfarande. Flera initiativ har genomförts för att komma till rätta med de identifierade problemen: samarbeten i olika forum, kostnadsfri tillgång till geodata för universitet och högskolor (via FUK-avtal), en förbättrad infrastruktur för geodata (genom forskning och regeringsuppdrag) samt utbildningssatsningar i tidig ålder (Geoskolan). Geodatarådets tidigare initiativ för att driva kompetensfrågorna i enlighet med 2012 års geodatastrategi har inte följts upp med motsvarande nya satsningar mellan åren 2016 till 2019.Det finns ett stort utbud av utbildningar inom geodataområdet utspridda på olika platser i Sverige. Kompetensförsörjningen inom geodataområdet är beroende av tillgången på välfungerande forskningsmiljöer. Goda forskningsmiljöer knyter till sig värdefulla resurser, exempelvis professorer, forskare, postdocs och doktorander. Förutom att bidra med kunskap och allokera ekonomiska resurser till forskning, förbättras lärosätenas möjligheter att kunna bedriva en attraktiv utbildning. Många gånger är en professur en nödvändighet för att åstadkomma den önskvärda forsknings- och utbildningsmiljön. Trots att flertalet utbildningsvarianter finns valbara vid ett antal lärosäten tycks tillgången på kompetens inte motsvara marknadens behov. Särskilt kritiskt tycks situationen vara för kompetenstillgången inom ämnesområdet fotogrammetri, där det idag inte finns någon profe-ssur i Sverige.Vid de tekniska högskolorna i Stockholm och Lund är söktrycket för de granskade utbildningarna gott, men få studenter väljer en inriktning mot geodata längre fram. Ämnesområdet geodata är relativt litet i förhållande till andra teknikområden och det finns en konkurrens mellan lärosätena. Detta har gjort ämnesområdet fragmentiserat med följden att inget lärosäte för närvarande tillhandahåller en komplett utbildnings- och forskningsmiljö. Det finns ett nationellt behov av en högkvalitativ masterutbildning som omfattar kärnämnena geodesi, fotogrammetri och geoinformatik. Om Sverige lyckas med att skapa en komplett masterutbildning som stöds av vitala forskargrupper bör det locka fler studenter till fortsätt utbildning, både på master- och forskarnivå. Forskningsverksamheten har flera viktiga funktioner i samhället. God forskning bidrar till att värna om Sveriges ställning som kunskapsnation och ger förutsättningar för vilken industri som etableras och stannar i landet. Aktiva forskargrupper bidrar till att skapa kompetensnätverk och får en särskild betydelse vid utbildningen av doktorander, lärare och studenter som sedan kan förse samhället med nödvändig expertkompetens. De ansträngningar som har gjorts för att försöka påverka forskningsfinansiärerna att prioritera geodataområdet har hittills varit fruktlösa. Medel får sökas inom ramen för andra forskningsprojekt. En långsiktig finansiell försörjning är en förutsättning för att forskning ska kunna bedrivas uthålligt och hålla en hög kvalitet. I Sverige finns det ingen utsedd huvudfinansiär för forskning inom geodataområdet, något som uppmärksammades redan i Geodatarådets utredning från 2008. Situationen ser likadan ut i dag, tillgången på forskningsmedel är bristfällig och det saknas en långsiktig forskningsförsörjning. I denna rapport presenteras en handlingsplan för att säkerställa den fram-tida kompetensuppbyggnaden inom geodataområdet. Arbetet bör initieras och följas upp av Geodatarådet samt utgöra en grund för inspel till kommande forskningsproposition (närmast år 2025) och dialog med berörda departement. Tre av de föreslagna aktiviteterna återges nedan:Arbeta för att skapa minst en komplett utbildnings- och forskningsmiljö som kan fungera som kompetenscentrum, och som inkluderar ämnesområdena geodesi, fotogrammetri (inklusive laserskanning) samt geoinformatik.Bilda en marknadsföringsgrupp med representanter från Geodatarådets medlemmar samt lärosäten och branschföretag som tillsammans arbetar fram en gemensam handlingsplan med aktivi-teter och kampanjer för att öka söktrycket till utbildningar med inriktning mot geodata.Ge Lantmäteriet ett forskningsfinansierande uppdrag. Formerna för ett sådant uppdrag behöver utredas närmare med andra forsknings-finansierande myndigheter som förebild. Denna lösning kräver ändringar i Lantmäteriets instruktion samt ett höjt ramanslag vilket måste tas med i beräkning vid ärendets beredning.

Engineering rubber bushing stiffness formulas including dynamic amplitude dependence
- 2006
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Engineering design models for the torsion and axial dynamic stiffness of carbon black filled rubber bushings in the frequency domain including amplitude dependence are presented. They are founded on a developed material model which is the result of applying a separable elastic, viscoelastic and friction rubber component model to the material level. Moreover, the rubber model is applied to equivalent strains of the strain states inside the torsion or axial deformed bushing previously obtained by the classical linear theory of elasticity, thus yielding equivalent shear moduli which are inserted into analytical formulas for the stiffness. Therefore, unlike other simplified approaches, this procedure includes the Fletcher-Gent effect inside the bushing due to non-homogeneous strain states. The models are implemented in Matlab®. In addition, an experimental verification is carried out on a commercially available bushing thus confirming the accuracy of these models which become a fast engineering tool to design the most suitable rubber bushing to fulfil user requirements. Finally, they can be easily employed in multi-body and finite element simulations

Geodetic SAR for Height System Unification and Sea Level Research - Results in the Baltic Sea Test Network
- 2022
-
Ingår i: Remote Sensing. - : MDPI. - 2072-4292. ; 14:14
-
Tidskriftsartikel (refereegranskat)abstract
- Coastal sea level is observed at tide gauge stations, which usually also serve as height reference stations for national networks. One of the main issues with using tide gauge data for sea level research is that only a few stations are connected to permanent GNSS stations needed to correct for vertical land motion. As a new observation technique, absolute positioning by SAR using off the shelf active radar transponders can be installed instead. SAR data for the year 2020 are collected at 12 stations in the Baltic Sea area, which are co-located to tide gauges or permanent GNSS stations. From the SAR data, 3D coordinates are estimated and jointly analyzed with GNSS data, tide gauge records and regional geoid height estimates. The obtained results are promising but also exhibit some problems related to the electronic transponders and their performance. At co-located GNSS stations, the estimated ellipsoidal heights agree in a range between about 2 and 50 cm for both observation systems. From the results, it can be identified that, most likely, variable systematic electronic instrument delays are the main reason, and that each transponder instrument needs to be calibrated individually. Nevertheless, the project provides a valuable data set, which offers the possibility of enhancing methods and procedures in order to develop a geodetic SAR positioning technique towards operability.

Kungen, fogdarna och riket : Lokalförvaltning och statsbyggande under tidig Vasatid
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The growth of the 16th century Swedish state is studied through the local organization created by Gustavus Vasa. The state is viewed as an organization, a collective agent, which may function as a formidable instrument of power for those who can control it. The inspiration comes from Max Weber as well as theories on how modern firms come to exist and expand their activities.The main issue is to explain why Gustavus Vasa and his successors created a wide-embracing local organization run by the state. In most parts of Europe, the princes tried to strengthen their positions by acting through noble officials on the provincial level. In Sweden royal bailiffs took over the responsibility for the tax collection in the entire realm. These bailiffs were the only intermediates between the king and his subjects. This flat, non-hierarchical structure meant that the Swedish nobility in effect was left outside the royal administration.In the first years of the reign of Gustavus Vasa mobilization of political support was given top priority, as the new regime needed to establish its legitimacy. The civil administration also performed important military functions. In the years around 1540, the local organization co-operated with the district courts in compiling records on the tax-base of the realm. As the political situation stabilized, and the central government gained access to information on local resources, the state expanded its activities into new areas. Under the entrepreneurial leadership of Gustavus Vasa the bailiffs took over operations that had previously been performed within civil society. As a result, the local administration had to grow. After 1560 this expansion stopped, and the state administration instead became more differentiated. But the local bargaining between bailiffs and peasantry was still of great importance. It added an important dimension of flexibility to the system.This study also addresses the relationship between the royal bailiffs and the peasantry. The bailiffs often used harsh methods, but peasants' complaints could prove worth while, and there was room for acting out conflicts within the system. From the reign of Gustavus Vasa, a line of communication was opened between king and peasants, which helped increase the legitimacy of state government while at the same time securing access to first-hand information about local circumstances. The Swedish state thus was able to mobilize resources and political support for its activities on a lower level in society than most of its competitors could. The significance of this state building in local society is strongly emphasized in this dissertation.

Ordnade hushåll : Genus och kontroll i Jämtland under 1600-talet
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this study is to investigate how households acted in order to create and uphold different norms, and the effect these norms had on the construction of gender. Throughout the thesis it is argued that control was an important way to enforce certain norms, and thus make daily life work. In this context control means to have the right knowledge and to act in the right way. If you had knowledge about the norms, you could act in accordance with them, and you could also draw attention to those who did not act as they were supposed to. The main focus is on the master and the mistress of the house, who were the key figures within the household. The investigated area is Jamtland, with some examples from surrounding areas.The control executed and displayed by different people concerned formal norms, such as legislation, semi-formal norms, such as certain religious texts, and informal norms and practices in the local community. The household’s ability to control these norms is analysed in connection to three main areas: control over resources, such as property and labour, control over the household, which often meant ability to obtain knowledge of what was going on, and finally, self-control. Furthermore this investigation deals with those exposed to control, how they reacted and at times tried to evade the control carried out by others.According to the theory of Tomas Laqueur, the similarities between men and women were strongly emphasised during the 17th century. This thesis shows that the power or authority of men and women was equal in many areas, but it differed in others. The small differences in the capacity of men and women to run the household, were important in the creation of gender.

En ny sits. Humaniora i förvandlig: Vänbok till Margaretha Fahlgren
- 2008
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Humaniora har de senaste åren befunnit sig under debatt: utmanats, ifrågasatts och tvingats att förtydliga sina positioner och anspråk. Det har ökat möjligheterna att visa kraft och bredd, angelägenhet och förnyelseförmåga.I En ny sits – humaniora i förvandling illustreras denna förnyelse via olika rum i Engelska parken vid Uppsala universitet: huset i både symbolisk och bokstavlig mening med sin egen historia, sina fakulteter, undervisningssalar och sitt vackra bibliotek; de enskilda rummen bebodda av institutionerna och forskningen; det särskilda framgångsrika genusrummet eller Centrum för genusvetenskap och sist men inte minst framtidsrummet representerat av de unga forskarna.Över allt detta har dekanus Margaretha Fahlgren hållit sin kreativa och starka hand.
