The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. It is shown that it will be possible to discov

Popular Abstract in Swedish Bukspottkörteln (pankreas) består av en sekretorisk (exokrin) del, som producerar pankreassaft innehållande olika matspjälkningsenzymer vilka medverkar vid nedbrytningen av födan i tarmen, samt en hormoninsöndrande (endokrin) del, som producerar insulin och andra hormon vilka reglerar näringsomsättningen i kroppen. Vid en underproduktion av enzymer, exokrin pankreatisk Exocrine pancreatic insufficiency (EPI), resulting from disease (e.g. cystic fibrosis, chronic pancreatitis) or surgery (e.g. pancreectomy or pancreas duct ligation), leads to disorders in the digestive system, such as, maldigestion, malabsorption and finally malnutrition. Pancreatic duct-ligated (PDL) pigs have been used as a suitable large-animal model to study the conditions and treatment of EP

The study is based on monitoring data on the seasonal variation during four (1996-1999) vegetation periods, as well as long-term summer data on submerged vegetation, nutrients, light, phyto-plankton and zooplankton in Lake Krankesjon, a shallow, calcium-rich, moderately eutrophic take in southern Sweden. The lake has been in the clear water state with abundant submerged vegetation since the end of

Dispersive liquid-liquid microextraction (DLLME) and high performance liquid chromatography-diode array detection (HPLC-DAD) was presented for extraction and determination of Irganox 1010, Irganox 1076 and Irgafos 168 (antioxidants) in aqueous samples. Carbon tetrachloride at microliter volume level and acetonitrile were used as extraction and dispersive solvents, respectively. The main advantages

A large pulse of atmospheric Cl-36 generated by a limited number of nuclear tests peaked in the late 1950s to early 1960s. The corresponding enhanced Cl-36 deposition is seen in various glaciological archives in the Northern Hemisphere. The profile of the bomb spike recorded in firn layers at Vostok Station, central East Antarctica. has been measured by employing accelerator mass spectrometry (AMS

Purpose. To define the association between venous volume as measured with air-plethysmography and the duplex ultrasound measured diameter of incompetent perforator of the lower limb. Patients and methods. Thirty-six patients with chronic venous disease were investigated with air-plethysmography and duplex ultrasound. Venous volume and venous filling time was measured. Venous filling index was calc

BACKGROUND: Dietary factors are thought to have an important role in gastric and esophageal carcinogenesis, but evidence from cohort studies for such a role is lacking. We examined the risks of gastric cancer and esophageal adenocarcinoma associated with meat consumption within the European Prospective Investigation Into Cancer and Nutrition (EPIC) cohort. METHODS: A total of 521,457 men and women

Lifetime tests of solar reflector materials are eligible prior to application, to prove the stability of the optical properties. In this work, six reflector materials were aged outdoors and in a climatic test chamber. The surfaces of the samples were inspected using profilometry and optical microscopy. The total and specular reflectance spectra were measured using spectrophotometry and the weighte

Popular Abstract in Swedish Avhandlingen behandlar kapacitet i cirkulationsplatser. Kapaciteten för ett körfält i en tillfart kan beräknas med teorin för kritiska tidsavstånd. Denna bygger på interaktioner mellan fordon med företräde (överordnade fordon) och fordon som skall lämna företräde (underordnade fordon). Det kritiska tidsavståndet är det minsta tidsavstånd mellan två överordnade fordon soProblem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. Various components of this theory are discussed, models for headways in the multi-lane case and for the estimation of critical gaps for the two major streams being developed and being applied

Conclusions. Preoperative gentamicin in combination with vestibular 'prehab' offers a possibility to reduce postoperative malaise and speed up recovery and may be used for patients undergoing such surgery when there is remaining vestibular function. Objectives. Removal of pontine angle tumours in a patient with remaining vestibular function causes symptoms of acute vestibular loss. A simultaneous

Popular Abstract in Swedish Förbättrad patientsäkerhet och omvårdnad av patienter med höftraktur Intervention granskad i det nationella kvalitetsregistret RIKSHÖFT Varje år drabbas ca 18 000 personer i Sverige av höftfraktur efter fall. Höftfraktur är ett samlingsnamn för två frakturtyper i den övre delen av lårbenet. Den ena frakturtypen är lokaliserad till lårbenshalsen (cervikal fraktur) och dAim: Hip fractures are common and costly. The overall aim of this thesis was to explore how different clinical pathways influence safety and quality of care among patients with a hip fracture and to test the usefulness of the national quality register RIKSHÖFT as a working tool. The aim in paper I was to improve the outcome of patients with a hip fracture through optimized preoperative pain relief

Residual adsorptive activity of frits prepared by sintering silica gel particles used in capillary HPLC and electrochromatography can be significantly reduced by silanization. The adsorption of polar analytes on frits consisting of sintered normal-phase or reversed-phase silica gel before and after deactivation has been characterized by imaging with laser-induced fluorescence in combination with a

OBJECTIVES: To evaluate the prophylactic efficacy of the human papillomavirus (HPV) quadrivalent vaccine in preventing low grade cervical, vulvar, and vaginal intraepithelial neoplasias and anogenital warts (condyloma acuminata). DESIGN: Data from two international, double blind, placebo controlled, randomised efficacy trials of quadrivalent HPV vaccine (protocol 013 (FUTURE I) and protocol 015 (F

Inflammation and ischemia have a synergistic damaging effect in the immature brain. The role of tumor necrosis factor (TNF) receptors 1 and 2 in lipopolysaccharide (LPS)-induced sensitization and tolerance to oxygen-glucose deprivation (OGD) was evaluated in neonatal murine hippocampal organotypic slices. Hippocampal slices from balb/c, C57BL/6 TNFR1(-/-), TNFR2(-/-), and wild-type (WT) mice obtai

Anti-Ro(52/60) and anti-La constitute the hallmark autoantibodies in primary Sjögren's syndrome, being present in 40-70% of sera. Several anti-Ro/La assays exist, but antibody detection appears to be assay-specific, thus the aim of this study was to compare several anti-Ro/La assays. In total, 96 sera from individuals with primary Sjögren's syndrome and 114 healthy controls were tested for anti-Ro

Using the concepts of social norms and social reality, this chapter explores why legal reforms that aimed to facilitate the formalization of informal workers have largely failed to influence vulnerable groups in developing countries. It explores the use of legal reforms in order to achieve development and poverty reduction. Using empirical material from a qualitative study conducted in Colombia am

Within insect communities, the population ecology of organisms representing higher trophic levels, for example, hymenopterous parasitoids, may be influenced by the structure of their insect hosts. Using microsatellite markers and ecological data, we investigated the population structure of the specialist braconid wasp parasitoid, Lysiphlebus hirticornis Mackauer attacking Metopeurum fuscoviride, a

Popular Abstract in Swedish Esofagektomi (kirurgiskt avlägsnande av matstrupen) är ett omfattande ingrepp som främst utförs pga cancer, men som även utförs vid vissa godartade sjukdomar. Matstrupen sträcker sig från svalget, via bakre delen av bröstkorgen ned till övre delen av buken. Det anatomiska läget gör att man ur kirurgisk synpunkt oftast måste avlägsna matstrupen via en kombination av inciIn a prospective randomised study following oesophagectomy and gastric tube reconstruction patients with hand-sutured neck anastomoses were compared with patients with circular stapled chest anastomoses. The two groups had equal rates of anastomotic or conduit leaks of 7.3 % (3/41) and 7.1 % (3/42) and of benign anastomotic strictures of 19.5 % (8/41) and 28.6 % (12/42). Another prospective random
