Sweden has experienced many geomagnetically induced current (GIC) events in the past, which is obviously due to the high-latitude location of the country. The largest GIC, almost 300 A, was measured in southern Sweden in the earthing lead of a 400 kV transformer neutral during the magnetic storm on 6 April 2000. On 30 October 2003, the city of Malmo at the southern coast suffered from a power blac
Pressurized hot liquid water and steam were used to investigate the possibilities of extracting insecticides (carbofuran, carbosulfan, and imidacloprid) from contaminated process dust remaining from seed-pellet production. Extraction temperature was the most important parameter in influencing the extraction efficiency and rate of extraction, while varying the pressure had no profound effect. A cle
Abstract in Undetermined The aim of this study was to compare the differences between the level of whole quality of life and its subscales after receiving two common treatment of breast cancer in women with early stage of breast cancer. A double-blinded cohort study was done in 100 breast cancer patients with node positive that used fluorouracil, doxorubicin, cyclophosphamide (FAC) and docetaxel,
Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3
Popular Abstract in Swedish Min avhandling heter Knowledge and Survival in the Novels of Thomas Hardy (disputationsdag: 15 april 2000). Jag fokuserar på två sorters vetande: det traditionella, som jag kallar ‘det vardagliga’, och ‘det specialiserade’, som är knutet till modern vetenskaplig utveckling.Abstract This thesis identifies two different kinds of knowledge in Thomas Hardy's novels: the everyday, passed on from generation to generation, which is non-academic and closely bound to the local environment and its traditions; and the specialised, recorded in the printed word, which is the product of formal education and independent of the local community and its traditions. These two kinds o
Non-stretched laminar burning velocities, SL, of acetaldehyde + air mixtures at initial gas mixture temperatures, T, of 298, 318, 338, 348 and 358 K are reported for the first time. The flames were stabilized on a perforated plate burner at 1 atm using the heat flux method at conditions where the net heat loss from the flame to the burner is zero. Uncertainties of the measurements were analyzed an
Objectives. The aims were to develop auditing according to the APO (Audit Project Odense) method for measuring soft data, exemplified by a holistic view, and to test the instrument. Design. A descriptive study of the development of an APO chart and a test registration. Setting. Primary health care, Blekinge County, Sweden. Subjects. Ten general practitioners (GPs) were invited to transform categor
Hemicelluloses, which are abundant in nature and have potential use in a wide variety of applications, may make an important contribution in helping relieve society of its dependence on petrochemicals. However, cost-efficient methods for the isolation of hemicelluloses are required. This article presents an economic evaluation of a full-scale process to isolate hemicelluloses from process water fr
Interest in the use of renewable raw materials for the production of various compounds that can replace fossil-based products is steadily increasing. In this study, the extraction and separation of hemicellulosic oligomers from spruce, to be used for the production of polymers such as hydrogels, was investigated. The focus of the study was on gel filtration of the solution from steam treatment of
Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. Interatrial conduction disturbances and also delayed conduction at the posteroparaseptal region have also been reported as potential arrhythmogenic substrates. H
Background: Prospective follow-up of heroin users is known to be difficult due to their unstable lifestyle, and high follow-up rates have usually demanded major tracking efforts. In Sweden, mobile telephones are commonly used by heavy drug users for drug trading. Objectives: This methodology study aims to examine the efficacy of mobile telephone contact for prospective follow-up interviews with in
OBJECTIVE: The aim of this study was to investigate the effect of epidermal growth factor receptor (EGFR) blockade on cell survival and on downstream signalling pathways using the monoclonal antibody cetuximab. METHODS: We used three colon cancer cell lines, of which one was EGFR-negative, and two head and neck squamous cell carcinoma (HNSCC) lines. EGFR expression and gene copy number were measur
To aid informed health sector decision-making, data from sufficient high quality economic evaluations must be available to policy makers. To date, no known study has analysed the quantity and quality of available Iranian economic evaluation studies. This study aimed to assess the quantity, quality and targeting of economic evaluation studies conducted in the Iranian context. The study systematical
Detection and removal of sentinel lymph nodes (SLN) is important in the diagnosis and treatment of cancer. The SLN is the first regional lymph node draining the primary tumor, and if the cancer has spread, it is most likely to find metastases in the SLN. In this study, we have for the first time been able to image the very same contrast agent, superparamagnetic iron oxide nanoparticles (SPIO-NPs),
The combination of two differently charged polypeptides, poly-L-lysine (PL) and poly-L-glutamate (PG), has shown excellent postsurgical antiadhesive properties. However, the high molecular, positively charged PL is toxic in high doses, proposed as lysis of red blood cells. This study aims to elucidate the in vivo toxicity and biodistribution of PL and complex bound PLPG comparing intravenous and i
Hormonal replacement therapy (HRT) is generally regarded as first choice for pharmacological prevention of osteoporosis in women. We reviewed recent studies of HRT regimens and selective oestrogen receptor modulators (SERMs), including controlled trials of at least one-year duration published since 1995 until February 2000 providing data on bone mineral density (BMD) or fractures. Natural and synt
As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One's fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,
