Miscarriage—Evidence Based Information for the Web and Its Development Procedure  [PDF]
Annsofie Adolfsson, Emelie Arbhede, Elisabeth Marklund, Per-Göran Larsson, Marie Berg
Advances in Sexual Medicine (ASM) , 2015, DOI: 10.4236/asm.2015.54011
Abstract: Objective: The aim of this paper is to describe the process of developing web information on miscarriage based on scientific evidence, for women and couples in Sweden experiencing miscarriage. Method: A participatory design was used which included researchers, professional experts and users. A participatory design was used involving researchers, professional experts and users. The information was developed in six stages: 1) identifying the needs of information; 2) identifying and constructing the main areas of information and its paths; 3) identifying and inviting experts for revision; 4) developing the text; 5) reviewing the text; 6) design and structuring for adaption to website. Results: The text of information developed gradually based on the seven steps. The final text comprised three parts: 1) what is miscarriage; 2) experiences of miscarriage; 3) processing and planning for new pregnancy. Conclusion: Using participatory design was time and resource consuming, however it was functional for producing appropriate information for the target group. The developed evidence based facts text is assumed to be a complement to the information that is provided by the health care system.
Hot Love and Cold People. Sexual Liberalism as Political Escapism in Radical Sweden
Carl Marklund
Nordeuropaforum , 2009,
Abstract: The longstanding association of the “North” with “rationality” on the one hand and “Sweden” with “sex” on the other fulfilled a particular role in the philosophical geography of the radical 1960s and 1970s. By looking at works by Susan Sontag and Roland Huntford, this article proposes that Sweden could aid both radicals and conservatives in making sense of the “Western” heritage in an era of fundamental cultural change. While Sontag regarded sexual liberalism as part of a deeper fear of conflict, Huntford saw Swedish sexual liberalism as a result of political control. Both Sontag and Huntford agreed that in the end, the Swedes were not “authentically” liberated. This kind of “septentrionalism” helped Sontag and Huntford to construct a cultural compass with a negative North pole of cold, rational, and unnatural “modernity” as representative of elements which they both sought to combat in their respective home countries.
Invariant construction of solutions to Einstein`s field equations - LRS perfect fluids I
Mattias Marklund
Physics , 1996, DOI: 10.1088/0264-9381/14/5/028
Abstract: The properties of some locally rotationally symmetric (LRS) perfect fluid space-times are examined in order to demonstrate the usage of the description of geometries in terms of the Riemann tensor and a finite number of its covariant derivatives for finding solutions to Einstein's field equations. A new method is introduced, which makes it possible to choose the coordinates at any stage of the calculations. Three classes are examined, one with fluid rotation, one with spatial twist in the preferred direction and the space-time homogeneous models. It is also shown that there are no LRS space-times with dependence on one null coordinate. Using an extension of the method, we find the full metric in terms of curvature quantities for the first two classes.
Classical and quantum kinetics of the Zakharov system
M. Marklund
Physics , 2005, DOI: 10.1063/1.2012147
Abstract: A kinetic theory for quantum Langmuir waves interacting nonlinearly with quantum ion-acoustic waves is derived. The formulation allows for a statistical analysis of the quantum correction to the Zakharov system. The influence of a background random phase on the modulational instability is given. In the coherent case, the effect of the quantum correction is to reduce the growth rate. Moreover, in the classical limit, a bifurcation develops in the dispersion curves due to the presence of partial coherence. However, the combined effect of partial coherence and a quantum correction may give rise to an increased modulational instability growth rate, as compared to the classical case. The results may be of significance in dense astrophysical plasmas and laboratory laser-plasma systems.
Radiation transport in diffractive media
Mattias Marklund
Mathematics , 2005, DOI: 10.1088/0305-4470/38/19/015
Abstract: We consider radiation transport theory applied to non-dispersive but refractive media. This setting is used to discuss Minkowski's and Abraham's electromagnetic momentum, and to derive conservation equations independent of the choice of momentum definition. Using general relativistic kinetic theory, we derive and discuss a radiation gas energy-momentum conservation equation valid in arbitrary curved spacetime with diffractive media.
Impact of HPV in Oropharyngeal Cancer
Linda Marklund,Lalle Hammarstedt
Journal of Oncology , 2011, DOI: 10.1155/2011/509036
Abstract: The incidence of oropharyngeal cancers has increased in the western world and Human Papilloma Virus (HPV) has been recognised as a risk factor in the last decades. During the same period the prevalence of HPV in oropharyngeal tumours has increased and HPV has been suggested responsible for the increase. The HPV-positive tumours are today recognized as a distinct subset of head and neck cancers with its own clinopathological and risk profile and have a significantly improved prognosis regardless of treatment strategy. This review summarizes current knowledge regarding human papillomavirus biology, oncogenic mechanisms, risk factors, and impact of treatment. 1. Introduction Head and neck squamous cell carcinoma is the sixth most common cancer worldwide [1]. The incidence of head neck cancers varies widely around the world and even within populations. Oral and oropharyngeal cancer constitutes 3–5% of the malignancies in Europe, while this figure in parts of Southeast Asia and India reaches up to 40–50% [2–4]. Eighty to ninety percent of head and neck cancer cases are considered to be associated with known risk factors, such as smoking, betel nut chewing, and alcohol abuse [4, 5]. The prognosis for HNSCC is generally low in the more advanced stages and there has been only a modest improvement in recent years and the treatment frequently sentences the patient to life-long sequelaes such as difficulties with swallowing, dryness of the mouth, esophageal strictures, and osteoradionecrosis. Head and neck cancer is a heterogeneous group that differs greatly in tumour aggressiveness and response to treatment. The treatment is today based on tumour stage which thus leads to suboptimal outcome for some patients. The identification of predictive markers is urgent to enable optimization of treatment and reduction of sequalae for the individual patient. Despite a decreasing incidence of head and neck squamous cell carcinoma in general, attributed to a decrease in the prevalence of smoking [6], the incidence of oropharyngeal SCC is rising [7–12]. Human papillomavirus (HPV) has for some time been suggested to be involved in the carcinogenesis of oropharyngeal cancer. The Agency for Research on Cancer (IARC) now recognizes HPV as a risk factor for oropharyngeal cancer, and accumulating molecular and epidemiological data now show that high-risk types of HPV are responsible for a subset of oropahryngeal cancer [13–15]. HPV-positive cancers cases are now in majority in the western world and these tumours are also shown to have better outcome than the HPV-negative patients.
SNP detection and prediction of variability between chicken lines using genome resequencing of DNA pools
Stefan Marklund, ?rjan Carlborg
BMC Genomics , 2010, DOI: 10.1186/1471-2164-11-665
Abstract: Genotyping with a 60 K SNP chip revealed polymorphisms within or between two divergently selected chicken lines for 31 363 SNPs, 48% of which were also detected using resequencing of DNA pools. SNP detection using resequencing was more powerful for positions with larger differences in allele frequency between the lines. About 50% of the SNPs with non-reference allele frequencies in the range 0.5-0.6 and 67% of those with frequencies > 0.9 could be detected. On average, ~3.7 SNPs/kb were detected by resequencing, with about 5% lower density on microchromosomes than on macrochromosomes. There was a positive correlation between the observed between-line SNP variation from the 60 K chip analysis and our proposed FSV score computed from the genome resequencing data. The strongest correlations on macrochromosomes and microchromosomes were observed when the FSV was calculated with total flanking regions of 62 kb (correlation 0.55) and 38 kb (correlation 0.45), respectively.Genome resequencing with limited coverage (~5X) using pooled DNA samples and three non-reference reads as a threshold for SNP detection, identified 50 - 67% of the 60 K SNPs with a non-reference allele frequency larger than 0.5. The SNP density was around 5% lower on the microchromosomes, most likely because of their higher gene content. Our proposed method to estimate the SNP variation (FSV) uses additional sequence information to better predict SNP informativity. The FSV scores showed higher correlations for SNPs with a larger difference in allele frequency between the populations. The correlation was strongest on macrochromosomes, probably due to a lower recombination rate.Next generation sequencing technologies and SNP-chip genotyping with genome-wide coverage are affordable high-throughput genomics tools that are now being used in many research projects. Thus, large amounts of data are being quickly generated that will increasingly require novel methods for efficient data mining and analysis. In man
On the ionospheric coupling of auroral electric fields
G. T. Marklund
Nonlinear Processes in Geophysics (NPG) , 2009,
Abstract: The quasi-static coupling of high-altitude potential structures and electric fields to the ionosphere is discussed with particular focus on the downward field-aligned current (FAC) region. Results are presented from a preliminary analysis of a selection of electric field events observed by Cluster above the acceleration region. The degree of coupling is here estimated as the ratio between the magnetic field-aligned potential drop, ΔΦII, as inferred from the characteristic energy of upward ion (electron) beams for the upward (downward) current region and the high-altitude perpendicular (to B) potential, ΔΦbot, as calculated by integrating the perpendicular electric field across the structure. For upward currents, the coupling can be expressed analytically, using the linear current-voltage relation, as outlined by Weimer et al. (1985). This gives a scale size dependent coupling where structures are coupled (decoupled) above (below) a critical scale size. For downward currents, the current-voltage relation is highly non-linear which complicates the understanding of how the coupling works. Results from this experimental study indicate that small-scale structures are decoupled, similar to small-scale structures in the upward current region. There are, however, exceptions to this rule as illustrated by Cluster results of small-scale intense electric fields, correlated with downward currents, indicating a perfect coupling between the ionosphere and Cluster altitude.
Observation of low frequency electromagnetic activity at 1000 km altitude
N. Ivchenko,G. Marklund
Annales Geophysicae (ANGEO) , 2003,
Abstract: We present a statistical study of low frequency fluctuations of electric and magnetic fields, commonly interpreted as Alfvénic activity. The data base consists of six months of electric and magnetic field measurements by the Astrid-2 microsatellite. The occurrence of the events is studied with respect to the location and general activity. Large regions of broadband Alfvénic activity are persistently observed in the cusp/cleft and, during the periods of high geo-magnetic activity, also in the pre-midnight sector of the auroral oval. Key words. Ionosphere (auroral ionosphere) – Space plasma physics (waves and instabilities) – Magnetospheric physics (magnetosphere-ionosphere interactions)
Acceptance and Conformity Merging Modernity with Nationalism in the Stockholm Exhibition in 1930
Carl Marklund,Peter Stadius
Culture Unbound : Journal of Current Cultural Research , 2010,
Abstract: This article takes a closer look at how interwar supporters of modernism sought to overcome the opposition they had to face. It does so by looking at the usage of history and Swedishness at the Stockholm Exhibition in 1930 and contrasting this experience with a brief excursus on the image of progress and Americanism as presented at the A Century of Progress International Exposition, held in Chicago in 1933–1934. The backers of both these exhibitions – functionalist architects and progressive businessmen, respectively – consciously sought to find ways in which to savor the propagandistic value of this “the shock of the new” while retaining a reassuring continuity between well-known and widespread self-identifications with “the idyll of the past.” They did so by forging “national” forms of modernity, attempting to bypass the political conflicts and ideological polarizations which characterized the interwar years. As such, it is argued, they also exemplify how the logic of the exhibition could be used for harnessing technology, science, and funkis (functionalism) as tools for re-identifying the nation with modernity and simultaneously de-politicizing modernism.
