The contribution of forest harvesting to base cation losses and soil acidification has increased in recent years in Sweden, as the demand for bioenergy has increased and the sulphur deposition has decreased. Thus, new policy tools are required to evaluate the progress of the recovery from acidification, and as a basis for forest management recommendations. In this study we introduce and test a con
Background: Sweden has closed all institutions and imposed legislation to ensure service and support for individuals with intellectual disability (ID). Understanding mortality among older individuals with ID is essential to inform development of health promotion and disease control strategies. We investigated patterns and risk of mortality among older adults with ID in Sweden. Methods: This retros
Physiological processes of terrestrial plants regulate the land-atmosphere exchange of carbon, water, and energy, yet few studies have explored the acclimation responses of mature boreal conifer trees to climate change. Here we explored the acclimation responses of photosynthesis, respiration, and stomatal conductance to elevated temperature and/or CO2 concentration ([CO2]) in a 3-year field exper
This thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique. Speech is the practice of producing and understanding utterances. A technique is the organizing mechanism of speech, the structure that gives it a regular form. While speech is heavily dependent on context and interpretation, a technique is unaffected by theThis thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique. Speech is the practice of producing and understanding utterances. A technique is the organizing mechanism of speech, the structure that gives it a regular form. While speech is heavily dependent on context and interpretation, a technique is unaffected by the
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
Background. To evaluate the relationship between age and poor ovarian response to pregnancy and cancellation rate after IVF stimulation. Methods. Poor ovarian response was defined as <= 5 follicles at ovum pick up (OPU). Out of 1,706 consecutive OPUs performed during 2003/2004, 290 poor responders were identified. This cohort of poor responders was divided into two groups, 'older' and 'younger', w
The effect of pH on the kinetics of the bioelectrocatalytic reduction of H2O2 catalysed by horseradish peroxidase (HRP) has been studied at –50 mV vs. AgjAgCl on HRP-modified Au electrodes placed in a wall-jet flow-through electrochemical cell. Native HRP (nHRP) and a nonglycosylated recombinant form containing a six-histidine tag at the C-terminus, CHisrHRP, produced by genetic engineering of non
The study presents a hydrology concept developed to include lateral water flow in the biogeochemical model ForSAFE. The hydrology concept was evaluated against data collected at Svartberget in the Vindeln Research Forest in Northern Sweden. The results show that the new concept allows simulation of a saturated and an unsaturated zone in the soil as well as water flow that reaches the stream compar
Europe is one of the world's largest food producers, and climate change may pose a serious threat to food security in the region. In the present study, we assess the potential impact of climate change on the Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say)-a severe pest of potato (Solanum tuberosum, L.). We also investigate the possible impact of climate change on the phenological dev
Solid fuel fired fluidized bed (FB) boilers are common in combined heat and power (CHP) plants in district heating- and process industry. In this study, utilization of such FB boilers for production of syngas in dual fluidized bed gasifiers and subsequent catalytic biofuel production to substitute natural gas (SNG), methanol (MeOH) and Fischer-Tropsch fuel (FT) has been examined. Based on the hypo
Background: The time spent in nursing homes (NHs) by patients with Alzheimer’s disease (AD) might be influenced by many factors, e.g., sociodemographic and clinical characteristics, rate of disease progression, and concomitant disorders. Whether different aspects of cholinesterase inhibitor (ChEI) therapy (drug agent, dose, and duration) affect time spent in NHs has not been investigated. We studi
Harvesting of wood for bioenergy purpose will probably increase in importance in the future, in order to replace fossil fuel. However, the environmental impact of increased harvesting might be considerable, e.g. on soil and water chemistry, biodiversity and long-term productivity, and in this study we investigate thresholds for sustainable harvesting volumes. The study is based on scientific revie
BACKGROUND: Suggestive interventions such as hypnosis and therapeutic suggestions are frequently used to alleviate surgical side effects; however, the effectiveness of therapeutic suggestion intervention has not yet been systematically evaluated. In the present study, we tested the hypotheses that (1) suggestive interventions are useful for reducing postoperative side effects; (2) therapeutic sugg
The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. DHEAS is considered an inactive precursor, which is converted into androgens and estrogens via local metabolism in peripheral target tissues. The predictive value of serum DHEAS for fracture risk is unknown. The aim of this s
The atmospheric organic aerosol is a tremendously complex system in terms of chemical content. Models generally treat the mixtures as ideal, something which has been questioned owing to model-measurement discrepancies. We used an oxidation flow reactor to produce secondary organic aerosol (SOA) mixtures containing oxidation products of biogenic (α-pinene, myrcene and isoprene) and anthropogenic (m
Context: After an anterior cruciate ligament (ACL) injury, a majority of patients have a traumatic bone marrow lesion (BML, or bone bruise). The clinical relevance of posttraumatic lesions remains unclear. Objective: To explore the cross-sectional associations between traumatic BML volume and self-reported knee pain and symptoms among individuals within 4 weeks of ACL injury. Design: Cross-section
Background: Atrial fibrillation (AF) is a known risk factor for ischemic stroke. Electrocardiographic predictors of AF in population studies such as the Framingham Heart Study, as well as in hypertensive patients have demonstrated a predictive value of the P-wave duration for development of AF. QRS vector magnitude has had a predictive value in ventricular arrhythmia development. We aimed to asses
Objective: To examine the effect of photodynamic therapy (PDT) on experimental liver tumours in rats. Design: An experimental liver tumour model was used. Each of a group of Fats had two tumours simultaneously inoculated into its liver. The tumour located in the left hepatic robe was used for PDT, and the other one, in the median lobe, as a control. The haem precursor delta-amino laevulinic acid (
Popular Abstract in Swedish Förmågan att planera med en medveten mental simulering har ansetts vara unikt mänsklig sedan Aristoteles. När människor planerar för psykologiska eller fysiologiska driftstillstånd som de för närvarande inte upplever, tror man att de använder sig av så kallad episodisk framförhållning. Den episodiska framförhållningen är en del av det större episodiska kognitiva systemeThe ability to plan for future, not currently experienced, mental or physiological states has been regarded as unique to humans. When humans plan for such states it has been hypothesized that they make use of what has been known as episodic foresight. Episodic foresight is a part of the episodic cognitive system, which also includes episodic memory. The defining feature of this system is so-called
Objective: We used dual X-ray absorptiometry (DXA) to measure calcaneal bone mineral density (BMD) and estimate the prevalence of osteoporosis in a population with distal forearm fracture and a normative cohort. Methods: Patients 20 to 80 years of age with distal forearm fracture treated at one emergency hospital during two consecutive years were invited to calcaneal BMD measurement; 270 women (81
