The hygroscopic growth of the atmospheric aerosol is a critical parameter for quantifying the anthropogenic radiative forcing. Until now, there has been a lack of long term measurements due to limitations in instrumental techniques. In this work, for the first time the seasonal variation of the hygroscopic properties of a continental background aerosol has been described, based on more than two ye
Based on 43 interviews conducted with employees who spend around half of their working-hours on non-work related activities such as cyberloafing', a typology of empty labour is suggested according to sense of work obligation and potential output in order to set the phenomenon of workplace time-appropriation into a theoretical context in which wasteful aspects of organization and management are tak
We have measured the He and Ne concentrations and isotopic ratios of individual sediment-dispersed extraterrestrial chromite grains (63-180 mu m in diameter) from an Ordovician limestone in southern Sweden. In the same sediment, many fossil meteorites were found and have been attributed to the L chondrite parent body breakup event similar to 470 Ma ago. In this analysis of 37 individual extraterre
This study investigates the mechanisms of (de)coding modality, focusing on the interpretation of utterances containing the modals must, may, måste, and kan. The main research question posed in this study is what enables the interlocutors to interpret modal expressions so that communicative goals are achieved. To answer this general question, Coates's (1983) study on modal contexts is initially rep
Popular Abstract in Swedish De senaste 25 åren har flera nya narkosläkemedel registrerats och fått stort genomslag i vårt land. Den främsta orsaken är att dessa läkemedel medger ett snabbare uppvaknande och bättre postoperativt välbefinnande, vilket gör att många patienter snabbare kan återvända hem efter sina operationer. Propofol (2,6-di-isopropylfenol) som är ett av våra mest använda intra-venö
Popular Abstract in Swedish Att mäta det icke observerbara: Vilka chefer väljs till toppositioner? Rekrytering och urval av chefer präglas till stor del av informationsosäkerhet. Det är svårt att utvärdera chefers prestationer, då deras ansvarsområde består av så många aspekter, då de behöver stor frihet i sitt arbete och därför inte kan kontrolleras alltför mycket och då deras arbete påverkas avRecruitment and selection of managers is to a large degree characterized by information uncertainty. Managers’ performance is difficult to evaluate, as their responsibility consists of so many different aspects, as they may not always be observed due to need for freedom of action and as their work is affected by factors in their environment, which are outside of their control. Also, selection deci
According to the traditional view, the relation between morphology and syntax is the following: while morphology builds up word forms—typically by combining roots with other roots and with affixes, but also by applying other operations to them, syntax takes fully inflected words as input and combines them into phrases and sentences. The division of labour between morphology and syntax is thus perf
The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. Photosynthetic oxygenation overcomes these limita
Aims: To illuminate patients' experiences of being cared for and nurses' experiences of caring for patients in a multiple-bed hospital room. Background: Many patients and healthcare personnel seem to prefer single-bed hospital rooms. However, certain advantages of multiple-bed hospital rooms (MBRs) have also been described. Method: Eight men and eight women being cared for in a multiple-bedroom
Hairy cell leukemia is often reported as a disease of young males. The male predominance is strong, 4:1, but the median age in the Swedish national compulsory cancer registry is similar to that of follicular lymphoma, i.e. 62 years. The overall 6-year survival in the Swedish registry of patients diagnosed since 2000 is 80%, 93% of patients <60 years, and 68% of those >60 years. The yearly risk of
Popular Abstract in Swedish I denna avhandling studerar jag tvådimensionella geometriska optimeringsproblem. Gemensamt för många praktiskt och teoretiskt intressanta problemställningar inom området är att det är mycket svårt att ta fram optimala lösningar. Det tar helt enkelt alltför lång tid att undersöka alla möjligheter för probleminstanser med stora mängder indata då beräkningstiden växer expoIn this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. The work done in this thesis is a contribution to the research directed at attacking and coping with such NP hard problems in computational geometry
Popular Abstract in Swedish Utbredningen av besvär som attribueras till elektrisk utrustning respektive kemikalielukter och andra odörer är ännu ej till fullo fastställd. Vidare saknas kunskap om eventuella bakomliggande faktorer för dessa besvärs uppkomst. Syftet med avhandlingen var att undersöka utbredningen av besvär som attribueras till elektriska faktorer, kemikalier och lukter, samt undersSelf-reported annoyance from electrical equipment has been in evidence since the mid-eighties, and the first reports of illness from everyday chemicals arose already in the 1960?s. However, the extent of the problem or the mechanisms behind the development of environmentally related annoyance has not yet been fully established. Increased vulnerability to stress has been suggested to be a possible
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall ac
Over the past decades, men’s and women’s time use has changed dramatically suggesting a gender revolution across industrialized nations. Women increased their time in paid work and reduced time in unpaid activities. Men increased their time in unpaid work, but not enough to compensate. Thus, women still perform more unpaid work irrespective of context. We investigate developments regarding men’s a
Background and objective: Patients diagnosed with grade group (GG) 1 prostate cancer (PCa) following treatment for benign disease (“incidental” PCa) are typically managed with active surveillance (AS). It is not known how their outcomes compare with those observed in patients diagnosed with GG1 on biopsy. We aimed at determining whether long-term oncologic outcomes of AS for patients with GG1 PCa
The biogeophysical forcing resulting from the change in land-surface properties (such as albedo) is of particular interest as it can increase, decrease, or offset the biogeochemical forcing resulting from the changes in atmospheric greenhouse gas concentrations due to deforestation, forest management, or reforestation/afforestation (i.e., land-use/land-cover change, LULCC). Moreover, the biogeophy
1. In rat isolated hepatic arteries contracted with phenylephrine, acetylcholine and the calcium ionophore A23187 each elicit endothelium-dependent relaxations, which involve both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). However, the contribution of prostanoids to these responses, and the potential interaction between EDHF and other endothelium-derived relaxing fact
In the recovery phase after a radioactive release incident, it is important to be able to focus decontamination operations on the areas that contribute most to the radiation dose. Monte Carlo simulations were applied to determine the shielding effect of a building against radiation from various directions, also giving information on the dose contributions at various locations inside the building f
Context. The Galactic bulge is an intriguing and significant part of our Galaxy, but it is hard to observe because it is both distant and covered by dust in the disk. Therefore, there are not many high-resolution optical spectra of bulge stars with large wavelength coverage, whose determined abundances can be compared with nearby, similarly analyzed stellar samples. Aims. We aim to determine the d
