    Factor Analysis of the Individual Components of the Metabolic Syndrome Among Elderly Identifies Two Factors With Different Survival Patterns-A Population-Based Study2009In: Metabolic Syndrome and Related Disorders, ISSN 1540-4196, E-ISSN 1557-8518, Vol. 7, no 3, p. 171-177Article in journal (Refereed)
    Abstract [en]

    Background: Factor analysis reduces a set of directly measured variables into a smaller set of underlying factors representing unique statistically independent domains termed "factors." In middle-aged people, previous factor analyses of the components of the metabolic syndrome have identified two to four factors. Many of these analyses report blood pressure as one of these factors. Methods: We performed a factor analysis of the individual continuous components of the metabolic syndrome among 198 men and 203 women comprising 65% of all 75 year olds from the city of Vasteras in Sweden. Results: The metabolic syndrome comprised two factors. Factor 1, the metabolic factor, consisted of waist circumference, high-density lipoprotein cholesterol, triglycerides, and fasting glucose, whereas factor 2, the blood pressure factor, consisted of systolic and diastolic blood pressure. These two factors explained 58% (factor 1, 31%, and factor 2, 27%) of the total variation in men. The corresponding figures for women were 63% (factor 1, 36%, and factor 2, 27%). Factor 1 was significantly related to a decreased 10 years of survival for men, with a hazard ratio (HR) of 1.30 (95% confidence interval [CI] 1.07-1.58, P = 0.008), and nearly significantly for women, with a HR of 1.27 (95% CI 0.98-1.64, P = 0.071). In a pooled analysis adjusting for sex, known cardiovascular disease, and hypertension, high blood pressure, and current smoking, the HR for factor 1 was 1.20 (95% CI 1.02-1.49, P = 0.026). Factor 2 was not significantly related to survival. Conclusions: Factor analysis of the basic variables of the metabolic syndrome among 75 year olds from a general population identified a metabolic factor and a blood pressure factor. The former factor was significantly related to 10-year survival and the relationship remained after adjusting for known cardiovascular disease and hypertension and current smoking.

    Dietary intake and biomarker status of folate in Swedish adults2018In: European Journal of Nutrition, ISSN 1436-6207, E-ISSN 1436-6215, Vol. 57, no 2, p. 451-462Article in journal (Refereed)
    Abstract [en]

    PURPOSE: National data on folate status are missing in Sweden, and regional data indicate folate insufficiency in up to more than 25% of the study populations. The objectives were to determine folate intake and status in the adult Swedish population as well as identifying dietary patterns associated with beneficial folate status.

    METHODS: Folate intake was estimated using a web-based 4-d food record in adults aged 18-80 years (n = 1797). Folate status was measured as erythrocyte (n = 282) and plasma folate concentrations (n = 294). Factor analysis was used to derive a dietary pattern associated with a higher folate status.

    RESULTS: Median folate intake was 246 µg/day (Q 1 = 196, Q 3 = 304, n = 1797) and for women of reproductive age 227 µg/day (Q 1 = 181, Q 3 = 282, n = 450). As dietary folate equivalents (DFE), median intake was 257 µg/day (Q 1 = 201, Q 3 = 323) and for women of reproductive age 239 µg/day (Q 1 = 185, Q 3 = 300). Low blood folate concentrations were found in 2% (erythrocyte concentrations <317 nmol/L) and 4% (plasma concentrations <6.8 nmol/L) of the participants, respectively. None of the women of reproductive age had erythrocyte folate concentrations associated with the lowest risk of neural tube defects. Dietary patterns associated with higher folate status were rich in vegetables, pulses and roots as well as cheese and alcoholic beverages, and low in meat.

    CONCLUSIONS: Prevalence of low erythrocyte folate concentrations was low in this population, and estimated dietary intakes are well above average requirement. However, to obtain a folate status optimal for prevention of neural tube defects major dietary changes are required and folic acid supplements recommended prior to conception.

    Synchrotron radiation excited photoelectron spectrum of H2(+) with rotational resolution1999In: J. Phys. B: At. Mol. Opt. Phys, ISSN ISSN 0953-4075, Vol. 32, no 3, p. L51-L56Article in journal (Refereed)
    Abstract [en]

    The rotational branching ratio in the photoelectron spectrum of H-2(+) has been investigated using synchrotron radiation. At the photon energy hv = 27 eV, the S (Delta N = 2) branch has a considerably higher relative intensity than when excited with He I (lambda=584 Å, hv=21.218 eV) or with Ne I (lambda=736 Å, hv=16.848) radiation.

    A new energy and angle resolving electron spectrometer - First results2011In: Journal of Electron Spectroscopy and Related Phenomena, ISSN 0368-2048, E-ISSN 1873-2526, Vol. 183, no 1-3, p. 125-131Article in journal (Refereed)
    Abstract [en]

    A new energy and angle resolved analyzer for photoelectron spectroscopy is described. This analyzer is based on combining an advanced focusing electron lens system with time-of-flight measurements. A position sensitive detector gives time and position for the electron events. From this information the kinetic energy and start direction are obtained through a transformation procedure, giving both a large luminosity and a very high energy resolution. The instrument analyses the angles of emission of the electrons in a cone with 30 degrees opening angle and simulations show that extremely high energy and angular resolution can be achieved simultaneously. We report the first results from this instrument, obtained at the PM-3 beam line at BESSY (Berlin, Germany). This analyzer opens up new possibilities for angular resolved electron spectroscopy, band-mapping and other applications.

    Photofragmentation of cyanogen upon carbon and nitrogen K-shell excitation by partial ion yield experiments2010In: Journal of Physics B: Atomic, Molecular and Optical Physics, ISSN 0953-4075, E-ISSN 1361-6455, Vol. 43, no 9, p. 095201-Article in journal (Refereed)
    Abstract [en]

    Partial ion yield spectroscopy was used to study fragmentation processes in cyanogen after C 1s and N 1s photoexcitation. The interpretation of the core excitation spectrum mostly follows the literature, but the high resolution has in some cases allowed a more detailed assignment. Using the fact that in Rydberg states there is an intensity increase as the fragmentation process becomes more extensive compared to valence orbitals, we have been able to distinguish resonances with valence and Rydberg character. Furthermore, we have been able to assign features in the ionization continuum as arising from double excitations or shape resonances, by observation of the suppression of anion yield at shape resonances.

    UV-photoelectron spectroscopy of free atoms and molecules at near 1 meV resolution1999Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Results of ultraviolet photoelectron spectroscopy experiments on free atoms and moleculesare presented. The energy resolution and signal-to-noise ratio of the photoelectron spec-tra are such that several new observations have been possible.

    Photoelectron spectra of outer valence states of small molecules in the gas phase withrotational structure resolved have been obtained using newly developed equipment. Acorrelation between the outgoing photoelectron wave composition and the rotationalbranching ratio and photoelectron angular distribution has been noticed. A distinct de-pendence of photon energy has been observed in the rotational population of the X 2 Σ+gstate of N2+, which has been linked to a shape resonance in the photoelectron continuum.For the B 2Σ+u state of the same molecule, no such significant effect was found. Clearlydifferent angular distributions were observed for rotational branches corresponding todifferent changes in rotational angular momentum, both for N2 and H2 molecules. Inthe photoionization of the 1b1 orbital of water, mostly photoelectron waves with evenangular momentum seem to contribute, judging by a simple model used to interpret therotational line profile of the v' = (0,0,0) vibration. Since the 1b1 orbital almost is a pureO2p orbital, mostly s and d waves are expected to contribute, in agreement with what is observed.

    The inner valence spectrum of CO+ has been recorded and partly interpreted with helpof resonant Auger spectra. A resonant Auger decay spectrum of the Xe 4d-15/26p statehas been recorded in the resonant Raman regime, with a peak width of less than a tenthof the natural lifetime width of the intermediate state, allowing complete resolution of aparticular kinetic energy region.

    Charge Dependence of Solvent-Mediated Intermolecular Coster-Kronig Decay Dynamics of Aqueous Ions2010In: Journal of Physical Chemistry B, ISSN 1520-6106, E-ISSN 1520-5207, Vol. 114, no 51, p. 17057-17061Article in journal (Refereed)
    Abstract [en]

    The 2s and 2p photoelectron spectra have been measured for Na+, Mg2+, and Al3+ ions in aqueous solution.In all cases, the 2s lines are significantly broader than the 2p features, which is attributed to a shorter lifetimeof the respective 2s hole. Since intraionic Coster-Kronig decay channels from the (2s)-1 state are closed forfree Na+, Mg2+, and Al3+ ions, this is evidence for an intermolecular Coster-Kronig-like process, reminiscentof intermolecular Coulombic decay (ICD), involving neighboring water solvent molecules. The observed 2s Lorentzian line widths correspond to lifetimes of the (2s)-1 state of 3.1, 1.5, and 0.98 fs for the solvated Na,Mg, and Al ions, respectively.

    Reconnection With Magnetic Flux Pileup at the Interface of Converging Jets at the Magnetopause2019In: Geophysical Research Letters, ISSN 0094-8276, E-ISSN 1944-8007, Vol. 46, no 4, p. 1937-1946Article in journal (Refereed)
    Abstract [en]

    We report Magnetospheric Multiscale observations of reconnection in a thin current sheet at the interface of interlinked flux tubes carried by converging reconnection jets at Earth's magnetopause. The ion skin depth-scale width of the interface current sheet and the non-frozen-in ions indicate that Magnetospheric Multiscale crossed the reconnection layer near the X-line, through the ion diffusion region. Significant pileup of the reconnecting component of the magnetic field in this and three other events on approach to the interface current sheet was accompanied by an increase in magnetic shear and decrease in , leading to conditions favorable for reconnection at the interface current sheet. The pileup also led to enhanced available magnetic energy per particle and strong electron heating. The observations shed light on the evolution and energy release in 3-D systems with multiple reconnection sites. Plain Language Summary The Earth and the solar wind magnetic fields interconnect through a process called magnetic reconnection. The newly reconnected magnetic field lines are strongly bent and accelerate particles, similar to a rubber band in a slingshot. In this paper we have used observations from NASA's Magnetospheric MultiScale spacecraft to investigate what happens when two of these slingshot-like magnetic field lines move toward each other and get tangled up. We found that the two bent magnetic field lines tend to orient themselves perpendicular to each other as they become interlinked and stretched, similar to what rubber bands would do. This reorientation allows the interlinked magnetic fields to reconnect again, releasing part of the built-up magnetic energy as strong electron heating. The results are important because they show how interlinked magnetic fields, which occur in many solar and astrophysics contexts, reconnect and produce enhanced electron heating, something that was not understood before.

    Att samverka kring våldsbejakande extremism: En kvalitativ diskursanalys av svenska strategier och handlingsplaner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay studies the discourse about cooperation with the civil society within strategies and action plans considering violent extremism produced by the Swedish state and four different Swedish municipalities. The study also considers if some special actor from the civil society is mentioned more often than others in terms of cooperation. The analysis is implemented through a critical discourse analysis according to Fariclough and contextualized through Deans version of Foucaults theory about governmentality. The result shows that the discourse about cooperation used by the Swedish state impacts on the discourse used by the municipalities even though the municipalities use less harsh and imperative formulations. Religious communities are mentioned more often than other actors in terms of cooperation partners even though the documents rarely specify what kind of religious community they mean. This can partly be explained through the concept of “violent extremism” which leads to problems in actual cooperation and to feelings of alienation and stigmatization within different communities, especially Muslim.

Mitt syfte är att undersöka ifall det finns eller har funnits några skillnader mellan konstsagor skrivna av kvinnliga och manliga författare när det gäller personbeskrivande adjektiv och val av persongalleri. Analysmaterialet består av fyra årgångar Bland tomtar och troll (1913–1992) och hela analysmaterialet innehåller sex sagor av kvinnliga författare och sex sagor av manliga författare. Jag använder mig av både kvalitativa och kvantitativa metoder. Resultatet visar att det finns skillnader mellan sagor skrivna av kvinnliga och manliga författare och att dessa skillnader är störst i början av 1900-talet. Den mest påfallande skillnaden ligger i valet av persongalleri: de kvinnliga författarna föredrar prinsessor medan de manliga författarna föredrar hjältar. Resultatet visar också att de kvinnliga författarna beskriver sina personer mer utförligt än de manliga författarna.

    Abstract [en]

    Nine out of ten larger companies have an intranet today which is supposed to improve the communication withinthe company and save money. A great part of these intranets were established in the beginning of the 1990’swithout giving any thought to the users and their needs. How does the communication inside the corporationslook like when the intranets that are supposed to be the source for every information request, aren’t usable? Whatother sources do the users use and how much?The aim of this master thesis is to examine information source selection at a specific company. In addition,the aim is to study the companies intranet usability from the users’ perspective. Interviews with five employeesat Viking Line were carried out to analyze these questions. The empiric material also consists of a survey carriedout among 78 employees of the company. The principle of least effort and the cost/benefit model is introduced astwo possible theories that can explain the information source selection at the chosen company.The results show that the information source selection at the company cannot be explained by only onetheory or one model, in contrast to a great part of prior research. The selection of information source do dependon factors like perceived accessibility and perceived quality of the information but other factors are shown toaffect information seeking decisions as well. Therefore, the empiric material shows that time pressure affectsusers’ choice of source selection to more accessible information sources. Another factor that can have an effecton the user is how one employee treats another. When the employee has been negatively treated at the momenthe is seeking information, the employee is more likely to use impersonal sources.Furthermore, the intranet at Viking Line is the most used as well as the most reliable source according tothe users, even though the intranet does not satisfy all needs of the employees. The users are also highly accustomedwith the intranet which increases its perceived accessibility.The conclusion of this study is that the principle of least effort and the cost/benefit model do indeed explainthe users’ choice of information source, but only partly. The study was conducted at a specific company but theconclusions drawn could be applied to other similar companies where intranets are a great part of the employeesinformation seeking. Finally, I believe, that the effectiveness of the employee is directly connected to the effectivenessof the information sources available at the company. Moreover, if companies improved their intranetsthe companies would become more effective.This paper is a two years master’s thesis in Library and Information Science.

    Integrated Antennas: Monolithic and Hybrid Approaches2006Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed.

    The possible use of micromachining techniques as a means of reducing substrate losses of antennas manufactured on low resistivity silicon wafers is investigated. Compact dipole, loop, and inverted-F antennas for the 20-40 GHz frequency range are designed, implemented, and characterized. The results show significantly improved antenna efficiency when micromachining is used as a post-processing step for on-chip antennas manufactured in silicon technology.

    High resistivity wafers are used in a commercial silicon germanium technology to improve the efficiency of dipole antennas realized using the available circuit metal layers in the process. Monolithically integrated 24 GHz receivers with on-chip antennas are designed and evaluated with regard to antenna and system performance. No noticeable degradation of the receiver performance caused by cross talk between the antenna and the integrated circuit is observed.

    For low frequency antenna arrays, such as base station antennas, hybrid integration of active devices within the antenna aperture is treated. A compact varactor based phase shifter for traveling wave antenna applications is proposed and evaluated. Electrically steerable traveling wave patch antenna arrays, with the phase shifters implemented in the same conductor layer as the radiating elements, are designed and manufactured in microstrip technology. It is experimentally verified that the radiation from the feed network and phase shifters in the proposed antenna configuration is small.

    Abstract [en]

    The integration of K-band (2040 GHz) full wavelength square wire- and slot-loop antennas on low resistivity (11-70 Omega cm) silicon substrates is addressed. By the use of polymer or silicon oxide/nitride membranes to support the slot or wire loop over micromachined trenches the efficiency of the antennas is enhanced while the majority of the bulk silicon within the apterture of the antenna is preserved to enable the integration of active devices. A 3.6 x 3.6 mm(2) large slot loop antenna chip with 200 mu m micromachined trench width yields 1.5 dBi gain at 29.5 GM, while 1.0 dBi gain is obtained at 24 GHz for a wire loop antenna on a 4.5 x 4.5 mm(2) large chip with 360 mu m wide trenches.

    Abstract [en]

    A varactor diode based microstrip phase shifter for 5.8 GHz is presented. It is designed for use in microstrip traveling Wave antennas where there is a strict limitation on the available space for the phase shifters. To meet all requirements, a reflective type phase shifter is chosen. Such a phase shifter includes a hybrid coupler. A compact branch line coupler is designed to make the phase shifter fit between the radiating elements in the antenna, while maintaining sufficient electrical performance. Phase shifters are designed with different types of stubs connecting the diodes to ground. A phase tuning range of 621 is measured for a phase shifter with parallel open stubs, and 92 degrees with shorted stubs. Insertion loss is in both cases less than 0.6 dB. A complete five-element array antenna is built and characterized. Measurements show beam scanning angles within 32 degrees from broadside.

    Abstract [en]

    The design of electrically steerable traveling wave microstrip antenna arrays is presented. Varactor diode based phase shifters implemented on the same metallic layer as the patch elements are used to provide a variable progressive phase shift in the array. Two antennas for the 5.8 GHz ISM band, manufactured as single layer printed designs on a standard PTFE soft substrate, are demonstrated. A ten-element beam-tilting vertical array using transmission type phase shifters is realized, yielding between 11.8 to 13.9 dBi gain for the 0deg to 11deg beam tilt tuning range. Using wide phase tuning range reflection type phase shifters a five-element horizontally scanning array with -32deg to 32deg steering range and 10.9-11.3 dBi gain has been realized.
