The reduction of the (A root 5x root 5)R27 degrees surface oxide on Pd(100) and Pd75Ag25(100) surfaces by CO has been investigated by high-resolution X-ray photoelectron spectroscopy in combination with kinetic analysis using the Avrami-Erofeev theory. For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary
INTRODUCTION: Sex steroids are important for growth and maintenance of the skeleton. Catechol-O-methyltransferase (COMT) is an estrogen degrading enzyme. The COMT val158met polymorphism results in a 60-75% difference in enzyme activity between the val (high activity=H) and met (low activity=L) variants. We have previously reported that this polymorphism is associated with bone mineral density (BMD
Popular Abstract in Swedish Inledning I detta avhandlingsarbete studeras Mycoplasma pneumoniae (MP) och influensa virus ur olika perspektiv. Dessa två smittämnen orsakar båda årliga utbrott med luftvägsinfektioner som ibland blir omfattande epidemier. I båda fallen kan symptomen variera från lätta förkylningsbesvär till mycket svåra, ibland livshotande lunginflammationer. Infektion med MycoplasmaDiagnostic tests based on nucleic acid amplification have become available for Mycoplasma pneumoniae (MP) and influenza viruses. Here, an MP PCR test detected 100% of infections during the first three symptomatic weeks, whereas classical serology detected 21% week 1, 56% week 2, and 100% week 3. Positive PCR results were uncommon in healthy individuals. Levels of MP DNA were significantly higher i
Countries with abundant solar radiation have the potential to invest in simple technologies for deactivation of many bacteria and viruses in medical solid waste. In addition to the traditional Infection and Prevention Control (IPC) measures, these simple technologies contribute to better protection of health care workers in countries with compromised solid management schemes. Monitoring of tempera
The purpose of this essay has been to describe and analyze the planning and achievement of the aftercare in the coercion car law (LVM), applied to addicts in Sweden. To achieve this, we have conducted qualitative interviews with social workers and politicians in three Swedish municipalities. Our issue has been related to the following topics: · How does the social service look upon LVM? · In what
The objective in this research has been to predict the current and future moisture and temperature distribution in a concrete reactor containment, RC. The overall objective in this project was to create a model to be able to predict the moisture and temperature distribution in the concrete wall of the RC of a Pressurized Water Reactor, PWR. In addition, one objective was to design a model to simul
Popular Abstract in Swedish Att bedöma välbefinnande hos patienter med mag/tarmcancer Avhandlingen handlar om undernäring, beroende/oberoende i det dagliga livet och uppfattningar om hälsorelaterad livskvalitet hos patienter som opereras pga cancer i mag/tarmkanalen. Enligt journaldokumentation hos 45 patienter som opererades 1985-89, för cancer i bukspottkörteln, hade patienterna ett försämrat nThe aim was to study some aspects of patients´ well-being, related to nutrition, activities of daily living and health related quality of life, when undergoing major gastrointestinal cancer surgery. Chart documentations (N=45) of patients undergoing subtotal pancreatectomy were studied, and showed the patients' well-being to be affected, although it was not possible to fully evaluate the results o
Background:Rectal cancer patients commonly benefit from neoadjuvant therapy before resection surgery. For these patients, an elective ostomy diversion is frequently considered, despite the absence of conclusive evidence when a diversion is advantageous. This is a retrospective observational single-center study on a 4-year consecutive rectal cancer cohort undergoing neoadjuvant therapy, aiming at i
Objectives: To assess the existence of international, scientifically validated methods for manual surgical skills training and assessment. The aim was to create a descriptive chronological summary of the existing evidence and conclusions in the included articles. Methods: PubMed and Scopus were searched twice for reviews published between 1997 and October 2023 and between 1997 and January 2024. Th
The purpose of this study is to compare and analyze cash-for-care regulatory policies for the elderly long-term care in three countries, Germany, Sweden, and the UK, and to seek policy implications in preparation for regulatory policies that are suitable for the direction of South Korea’s welfare state and the socio-cultural environment. For this purpose, each country’s cash-for-care regulatory po
Background: Laparoscopic cholecystectomy (LC) is performed by surgeons from various specialties and remains central to minimally invasive surgical training. This study assessed whether surgeon subspecialty affects patient outcomes and explored aspects of LC education. Methods: This population-based study included 46,700 LCs performed between 2020 and 2023, using data from the Swedish Registry for

This study reports carbon and water fluxes between the land surface and atmosphere in eleven different ecosystems types in Sub-Saharan Africa, as measured using eddy covariance (EC) technology in the first two years of the CarboAfrica network operation. The ecosystems for which data were available ranged in mean annual rainfall from 320 mm (Sudan) to 1150 mm (Republic of Congo) and include a spect
This paper is a part of a research project studying human interaction with lighting control devices in public indoor environments. Factors such as the perception of the environment or objects may guide human behavior, therefore the perception of lighting related objects may have an impact on the behavior toward energy saving. This paper reports the development of a questionnaire for measuring huma
We have studied the ability of divalent cations to restore to normal axonal transport (AXT) which was inhibited by deprivation of Ca2+ and/or Mg2+ ions. The epi- and perineurium of the frog sciatic nerve were damaged by a 30-s wash in Triton X-100 containing frog Ringer's. This treatment did not affect either AXT or nerve levels of Ca2+ and Mg2+, but made the ions more easily extractable with a Ca
BACKGROUND Marked changes have occurred in in vitro fertilization (IVF) methodology during the past 25 years but also in characteristics of couples undergoing treatment. METHODS This study was based on 27 386 women undergoing IVF treatment from 1982 to 2006 and giving birth to 31 850 infants. Outcomes of deliveries were studied using Swedish health registers. Comparisons were made with all deliver
Hollow fibre (HF) membrane modules were applied in continuous mode for equilibrium sampling through membranes (ESTM) of polar organic pollutants. Phenolic compounds (chlorophenols, cresols and phenol) served as model substances and ESTM was tuned towards the measurement of freely dissolved concentrations (C(free)). HF membrane modules were constructed using thin-walled membrane, 1-m module length
In this paper, the prediction accuracy of the PHS (predicted heat strain) model on human physiological responses while wearing protective clothing ensembles was examined. Six human subjects (aged 29 ± 3 years) underwent three experimental trials in three different protective garments (clothing thermal insulation Icl ranges from 0.63 to 2.01 clo) in two hot environments (40 °C, relative humidities:
This study assessed: (i) how the magnitude and direction of principal strains vary for different sideways fall loading directions; (ii) how the principal strains for a sideways fall differ from physiological loading directions; (iii) the fracture mechanism during a sideways fall. Eleven human femurs were instrumented with 16 triaxial strain gauges each. The femurs were non-destructively subjected
