The most important issue in this dissertation will be a discussion concerning metal age flint use in Scania. Since flint tools from the Bronze and Iron Ages and Medieval times have rarely been examined, there are few general guidelines in typology or morphology. It is quite clear that conversions of existing Stone Age typological schemes are unsuitable when one intends to study the often simple an
Background. Current evidence suggests that high red meat intake is associated with increased colorectal cancer risk. High fish intake may be associated with a decreased risk, but the existing evidence is less convincing. Methods: We prospectively followed 478040 men and women from 10 European countries who were free of cancer at enrollment between 1992 and 1998. Information on diet and lifestyle w
OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.
The spectroscopic properties of spirilloxanthin in an nhexane solution and bound to the core light-harvesting LH1) complex of Rhodospirillum rubrum were studied by near infrared ultrafast transient absorption spectroscopy. Global analysis of the kinetic traces measured after excitation of spirilloxanthin to the S2 (1Bu +) state enabled us to estimate the species-associated difference spectra that
We study how the results of molecular dynamics (MD) simulations are affected by various choices during the setup, e.g., the starting velocities, the solvation, the location of protons, the conformation of His, Asn, and Gln residues, the protonation and titration of His residues, and the treatment of alternative conformations. We estimate the binding affinity of ligands to four proteins calculated
The Late Ordovician is a period of major global environmental changes. Its understanding requires an integrated stratigraphical approach. Here, chitinozoan assemblages are described from the Borenshult-1 drillcore from Motala (Sweden) and related to stable carbon isotope event stratigraphy. Fifty-six rock samples, corresponding to a stratigraphic interval ranging from the upper Sandbian to Llandov
Knowledge of feeding rates is the basis to understand interaction strength and subsequently the stability of ecosystems and biodiversity. Feeding rates, as all biological rates, depend on consumer and resource body masses and environmental temperature. Despite five decades of research on functional responses as quantitative models of feeding rates, a unifying framework of how they scale with body
The Lymphedema Quality of Life Inventory (LQOLI) is an instrument developed for patients with different types of lymphedema. It contains physical, emotional, social, and practical dimensions and consists of 58 items, each with three sub items concerning life quality, daily life changes, and difficulties of changing and two items concerning life quality in general and in relation to lymphedema. The
OBJECTIVE: To present our results of non-surgical primary management of appendiceal abscesses using ultrasonic percutaneous drainage under local anaesthesia, and selective interval appendicectomy. DESIGN: Retrospective study. SETTING: University hospital, Sweden. SUBJECTS: 24 patients with appendiceal abscesses 3-12 cm in size. INTERVENTIONS: Primary ultrasonic percutaneous drainage under local an
Enzyme replacement is a potential therapy for mucopolysaccharidosis I (MPS I), a lysosomal storage disorder caused by alpha-L-iduronidase deficiency. Previous work showed improvement in the tissues of MPS I dogs treated intravenously for 3 months with recombinant human alpha-L-iduronidase (25,000 units or approximately 0.1 mg/kg/week). We have now treated an MPS I-affected dog for 13 months to ass
Background: Epidemiologic studies of associations between folate intake and breast cancer are inconclusive, but folate and other plant food nutrients appear protective in women at elevated risk. Objective: The objective was to examine the association between folate intake and the incidence of postmenopausal breast cancer. Design: This prospective study included all women aged >= 50 y (n = 11699) f
Popular Abstract in Swedish Spel om pengar har blivit ett utbrett fenomen i Sverige under 1990-talet, med spelbutiker, spelhörnor i varuhusen, spelmaskiner och spel med kort och på roulette på pubar, pizzerior och restauranger, samt spel på Bingo-Lotto hemma i vardagsrummet. Förutom den ökade tillgången till legala spelformer blir det allt vanligare med spel i miljöer och sammanhang där det inte fGambling has become widely accepted in Sweden during the 1990s, with betting shops, gambling machines and casino-like gambling in pubs and restaurants, as well as Bingo-Lotto in our living rooms. Beyond the expansion in availability of legal gambling opportunities, the most notable change is the shift from gambling in specific venues to gambling in a much wider range of social settings. The conseq
The reaction mechanism of propane ammoxidation was studied on an Al-Sb-V-W-oxide catalyst using a TAP-2 reactor system. Analyses of the responses from both high-speed pulse transients with reactants and TPD experiments were performed. Since the ammoxidation process with three reactants proceeds from propane to acrylonitrile over propylene as an intermediate, the experiments comprised oxidation of
The isolated amyloid substance in hereditary cystatin C amyloid angiopathy (HCCAA) is mainly composed of a cystatin C variant devoid of the 10 amino terminal amino acid residues of extracellular cystatin C from healthy individuals. We have developed a procedure for protein sequencing directly from agarose gel electropherograms and used this in conjunction with isoelectric focusing to investigate t
The inception of the sheet flow regime as well as the effects of the phase lag when the sheet flow regime is established were investigated for oscillatory flows and combined steady and oscillatory flows. A new criterion for the inception of sheet flow is proposed based on around 300 oscillatory flow cases from experiments. This criterion was introduced in the Camenen and Larson [Camenen, B., Larso
A systematic review of radiation therapy trials in several turnout types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for head and neck cancer is based on data from 39 randomized trials and I
Prostaglandin E1 has earlier been shown to decrease pulmonary platelet trapping (PPT) following shock. This experiment was performed to evaluate a new method to study PPT in vivo, and to study the effect of prostaglandin E1 and a new antiplatelet drug (ticlopidine) on PPT in rabbits after i.v. administration of endotoxin. Following platelet labeling with In-111, the rabbits were placed under a sci
A new way of preparing catalytically active wire meshes through a thermal-spray technique is described. A metal substrate (e.g. Kanthal AF) was plasma-sprayed with a composite ceramic/polymer-powder. The polymer content of the sprayed layer was burnt off whereupon a well-defined macro-porosity was created. By treating the so obtained material with an alumina-sol the specific surface area could be

Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. Spectroscopic methods, especially when combined with lasers, are idea
