Background:Groin pain in athletes is a common symptom and may, among many other entities, be caused by skeletal changes in the symphysis and the pubic bone or hernia. Material and Methods:Herniographies in 51 athletes - mainly soccer players - with unclear groin pain were reviewed. The prevalence of various hernias and skeletal changes at the symphysis and os pubis was registered. A questionnaire
One purpose of the present study is to explore the stability of the pattern of health/work and sickness absence among middle-aged women over a period of three years. This study tested two hypotheses: (a) that enduringly healthy working women would perceive more valued occupational roles and higher well-being than long-term sick-listed women; (b) that high levels of well-being at baseline would pre
Postantibiotic effects (PAEs), postantibiotic sub-MIC effects, and sub-MIC effects of the new nonfluoroquinolone PGE-9509924, ciprofloxacin, and levofloxacin against gram-positive and gram-negative strains were investigated. In comparison to ciprofloxacin and levofloxacin, PGE-9509924 exerted very similar PAEs against all strains except for both strains of Streptococcus pneumoniae, where longer PA
Popular Abstract in Swedish Varför beslutar politiker ibland att vidta till synes effektlösa åtgärder? Varför uppstår ibland stora politiska konflikter i små frågor? I vanliga fall vidtar man en politisk åtgärd därför att man eftersträvar det konkreta resultatet av åtgärden. Symbolpolitik är när en politisk fråga blir viktig, inte beroende på vad den konkret innebär och leder till, utan på grund aSymbolic politics is the degree to which political decision-making is motivated, not by the tangible aspects of the decision, but by the interpretation of what the decision represents symbolically. While symbolic politics is widely recognized as an important aspect of political decision-making, the phenomenon is insufficiently explored in political science. The first aim of the present dissertatio
Purpose: To examine whether panretinal photocoagulation for severe non-proliferative retinopathy in type 1 diabetes patients could halt the progression of retinopathy with subsequent vitreous haemorrhages and visual impairment. Methods: During a 10-year follow-up study period of 344 type 1 diabetes patients, 81 subjects went through panretinal photocoagulation. Forty patients were treated for sev
Popular Abstract in Swedish Programvara spelar en allt viktigare roll i industriella produkter. Bilar, flygplan, telefoner, hemelektronik, kärnkraftverk m.m. innehåller alla programvara. När man utvecklar programvara blir det ofta fel i produkterna, fel som kan vara mycket allvarliga för funktion och säkerhet. Ett första steg i att minska dessa fel är att uppskatta hur många fel som finns i produkIn software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. This thesis presents models for estimation of residual faults after inspections and a model for usage specifications which enables estimation of operational failu
OBJECTIVE: To explore the utility of cluster analysis in defining complex dietary exposures, separately with two types of variables. DESIGN:: A modified diet history method, combining a 7-day menu book and a 168-item questionnaire, assessed dietary habits. A standardized questionnaire collected information on sociodemographics, lifestyle and health history. Anthropometric information was obtained
Att golvbeläggningar som läggs på betong som inte fått torka ut ordentligt kan skadas är känt sedan länge. Under senare år har även avgivningen av luktande kemiska ämnen från golvsystem studerats närmare. Eftersom risken för skador ökar när betongunderlaget är fuktigt har det blivit allt vanligare att man ökar betongkvaliteten för att förkorta torktiden. Det har visat sig att nedbrytningen av lim
The force-velocity relation of the rat portal vein has been studied during regular spontaneous contractions induced by elevated levels of [K-+]O AND [Ca-2+]o. No satisfactory description of the force-velocity relation was obtained by measuring shortening velocity in afterloaded isotonic contractions. Therefore the method of isotonic quick release was used, as this permits mechanical studies at spe
The near-infrared electronic spectrum of AuO1 has been re-examined in light of the new microwave data on the nu = 0 and nu = 1 vibrations of the X-2 Pi(3/2) state of AuO. The two observed bands in the spectrum, with red-degraded bandheads located at 10726 and 10665 cm(-1), have been reanalyzed. New theoretical work on AuO clarifies the electronic structure, and the bands in the infrared are now as
We demonstrate that the multiple gluon emission phase space in the dipole cascade model has a strong linear correlation with the number of gluons emitted. The number of gluons per unit available phase space at a certain resolution scale is found to be remarkably independent of the cms energy and global event properties like thrust, and even changes in the ordering variable or resolution scale. We
Word-by-word logical AND and OR operation with photon-echo processing is demonstrated for what is to our knowledge the first time. The photon-echo process can store sequences of optical data before processing. The present logical operations on 8- and 4-bit words are performed by using single-shot frequency-chirped photon echoes. Data rates of approximately 1 MHz, input energies of 1-10 nJ/bit, and
A low-noise amplifier (LNA) and mixer circuit in 0.35-mum CMOS operates at 2.1 GHz. Merging the LNA and mixer lowers the number of transistors in the signal path and thereby also the nonlinearity and power consumption. The circuit meets the specifications for a direct conversion wide-band code-division multiple access (WCDMA) receiver. Its noise figure is 3.4 dB (5 kHz to 5 MHz), the total convers
SO2 dry deposition was studied over short vegetation, in Portugal, by means of the concentration gradient method. The experimental study involved one first phase of long-term measurements carried out in a grassland and, subsequently, a second period of several 1997 intensive field campaigns performed in three places representing different climate and surface conditions. Temporal and spatial patter
Anaerobic digestion of sludge has been part of the treatment plant in Malmo for many years and several projects on optimisation of the digestion process have been undertaken in full scale as well as in pilot scale. In order to facilitate a more sustainable solution in the future for waste management,solid waste organic waste is sorted out from households for anaerobic treatment in a newly built ci
