Catalytic CO oxidation is a seemingly simple reaction between CO and O2 molecules, one of the reactions in automotive catalytic converters, and the fruit-fly reaction in model catalysis. Surprisingly, the phase responsible for the catalytic activity is still under debate, despite decades of investigations. We have performed a simple but yet conclusive study of single crystal Rh and Pd model cataly
Using four bacterial immunoglobulin-binding proteins, we have analyzed the binding characteristics of a panel of 34 human single chain Fv antibodies, expressed in E. coli and with known specificity and sequence. Several of the single chain Fv antibodies showed affinity for staphylococcal protein A and peptostreptococcal protein L, but not for the streptococcal proteins G or H. The affinity of the
Protein L, a cell wall molecule of certain strains of the anaerobic bacterial species Peptostreptococcus magnus, shows high affinity for human immunoglobulin (Ig) light chains. In the present study protein L was tested against a panel of human myeloma proteins of the IgG, IgM, IgA and IgE classes, and strong binding was seen with antibodies carrying kappa light chains. A high degree of specificity
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
Over the past 3.5 million years, there have been several intervals when climate conditions were warmer than during the pre-industrial Holocene. Although past intervals of warming were forced differently than future anthropogenic change, such periods can provide insights into potential future climate impacts and ecosystem feedbacks, especially over centennial-to-millennial timescales that are often
Risk of dementia is increased in patients with atrial fibrillation (AF). We aimed to study associations between relevant comorbidities and prevalent as well as incident dementia in AF patients. Study population included all adults (n = 12,283) ≥ 45 years diagnosed with AF at 75 primary care centers in Sweden 2001–2007. Logistic regression was used to calculate odds ratios (OR) with 95% confidence
There is no consensus in the literature about the role of socioeconomic factors on influenza mortality during the 1918 pandemic. While some scholars have found that social factors were important, others have not. In this study, we analyzed differences in excess mortality by social class in Sweden during the 1918 pandemic. We analyzed individual-level mortality of the entire population aged 30–59,
Code stability is a matter of concern for three-dimensional (3D) fuel cell models operating both at high current density and at high cell voltage. An idealized mathematical model of a fuel cell should converge for all potentiostatic or galvanostatic boundary conditions ranging from open circuit to closed circuit. Many fail to do so, due to (i) fuel or oxygen starvation causing divergence as local
With well over 700 000 deaths every year worldwide, kidney disease constitutes an immense health problem for patients and society. The total global number of people with kidney disease regardless of severity amounts to a staggering 600 000 000. Not surprisingly, the total health care expenditure associated with kidney disease is second to no other costs, including oncology/cancer. If acute or chro
We analyze how much a core rational-choice model can explain the temporal and spatial variation in fertility and school enrollment in France during the 19th century. The originality of our approach is in our reliance on the structural estimation of a system of first-order conditions to identify the deep parameters. Another new dimension is our use of gendered education data, allowing us to have a
Global health spending share of low/middle income countries continues its long-term growth. BRICS nations remain to be major drivers of such change since 1990s. Governmental, private and out-of-pocket health expenditures were analyzed based on WHO sources. Medium-term projections of national health spending to 2025 were provided based on macroeconomic budgetary excess growth model. In terms of per
Equity refers to a fair sharing of costs or resources. Horizontal equity concerns distribution among individuals or groups with the same necessities, whereas vertical equity should be considered in situations with different levels of needs. This paper deals with transit service, looking at how to make it equitable from a spatial and social point of view. Traditionally equity has been neglected in
Intraductal papillary mucinous neoplasm (IPMN) is one of the most common cystic neoplasms of the pancreas. It is a heterogeneous disease and can be divided into ductal types and morphological subtypes. The incidence of IPMN is increasing, likely due to the widespread use of cross-sectional imaging and a growing elderly population. IPMN poses an increasing demand on the health care system. Current
Introduction: Severe obstetric complications increase with the number of previous cesarean deliveries. In the Nordic countries most women have two children. We present the risk of severe obstetric complications at the delivery following a first elective or emergency cesarean and the risk by intended mode of second delivery. Material and methods: A two-year population-based data collection of sever
