With the triumph of the codex, medieval literature became more deeply hermeneutic in character. A vast range of texts, in various languages and genres, were not only copied with the commentaries and glosses of ancient tradition, but also underwent continuous reworking and transformation. Indeed, the very act of transcribing texts into a manuscript was often an incentive to rewrite them. This pract
Heat has long been utilised as a therapeutic tool in medicine. Laser-induced thermotherapy aims at achieving the local destruction of lesions, relying on the conversion of the light absorbed by the tissue into heat. In interstitial laser-induced thermotherapy, light is focused into thin optical fibres, which are placed deep into the tumour mass. The objective of this work was to increase the under
Popular AbstractStörre kriser och katastrofer som stormen Gudrun och dess konsekvenser är sannolikt att vänta i framtiden. Det råder dock ovisshet om vilka kriserna kommer att vara och under vilka förutsättningar. Nya och kompletterande vetenskapliga studier och metoder inom kris- och katastrofforskningen måste till för att öka samhällets kunskap om och förmåga att hantera kända och okända hotbildSevere crises and disasters such as the Hurricane Gudrun and their consequences will probably occur in the future. However, there are many uncertainties concerning disasters and their effects. New scientific approaches and methods for crisis and disaster research must be developed to increase the knowledge and ability of societies to manage known and unknown threats. Substantial research on the em
Objective: To present the baseline data of the international TuberOus SClerosis registry to increase disease Awareness (TOSCA) with emphasis on the characteristics of epilepsies associated with tuberous sclerosis complex (TSC).Methods: Retrospective and prospective patients' data on all aspects of TSC were collected from multiple countries worldwide. Epilepsy variables included seizure type, age a
Marine microbes exhibit biogeographical patterns linked with fluxes of matter and energy. Yet, knowledge of the mechanisms shaping bacterioplankton community assembly across temporal scales remains poor. We examined bacterioplankton 16S rRNA gene fragments obtained from Baltic Sea transects to determine phylogenetic relatedness and assembly processes coupled with niche breadth. Communities were ph
Neutrophil influx to mucosal surfaces represents one of the earliest inflammatory responses to mucosal infection. We have been studying external interactions with urinary tract epithelial cells in an attempt to understand the molecular mechanisms behind this process. Uropathogenic Escherichia coli induced urinary tract epithelial cells to secrete the neutrophil chemoattractant interleukin-8 (IL-8)
The ambitious goal of the upcoming IEEE 802.11ax (HEW) standard for wireless LANs (WLANs) to enhance throughput by four times (and beyond), compared with IEEE 802.11ac, demands a radical improvement of present medium access control (MAC) functionality. To this end, a promising paradigm would be a graceful migration towards new MAC protocols which incorporate higher certainty in their decisions. Ho
This thesis treats scanning tunneling luminescence (STL) investigations of semiconductor nanostructures. The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in STM and the local excitation allow for optical investigations on the nanometer-scale. The work concerns design and implementation of an o
Breast cancer is the most common form of cancer in women. While the prognosis for breast cancer patients without local or distal dissemination is relatively favorable, the prognosis is considerably worse once distal metastasis has been established. It is therefore imperative to identify molecular targets and develop novel anti-metastatic therapies that will stop, reduce or delay the spread and gro
Interest in the generation of biogas from agricultural residues is increasing rapidly due to its climate benefits. In this study, an evaluation of the economic feasibility of various technologies, also on different scales, for the production of combined heat and power from manure-based biogas in Sweden is presented. The overall conclusion is that such production is not profitable under current con
Objectives: To evaluate whether, in patients with carcinoma in situ (CIS) of the urinary bladder, alternating instillation therapy with mitomycin C (MMC) and bacillus Calmette-Guerin (BCG) was more effective and less toxic than conventional BCG monotherapy. Methods: Patients were stratified prospectively for primary, secondary, and concomitant CIS and randomized to one of two regimens. Patients in
The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide positional andradial velocity measurements with the accuracies needed to produce astereoscopic and kinematic census of about one billion stars throughoutour Galaxy (and into the Local Group), amounting to a
OBJECTIVE: Between 1985 and 1994, 883 cases of acute pancreatitis were treated in Malmö, Sweden (population 233,000). The purpose of this study was to report the short- and long-term outcome of the 79 cases that were severe, according to the Atlanta classification. DESIGN: Retrospective and follow-up study a median time of 7 years since the attack. SETTING: University hospital, Sweden. SU
Objective: To assess mortality in patients with rheumatoid arthritis ( RA) treated with tumour necrosis factor (TNF) inhibitors, compared with a standard RA population. Methods: Patients were recruited from a regional register, which includes over 90% of patients with RA treated with TNF blockers in the area in 1999 or later, and a local community-based cohort of patients with RA, established in 1
The arctic fox Alopex lugopus excavates its dens in gravely ridges and hillocks, and creates a local environment quite distinct from the surrounding tundra or heath landscape. In northern Sweden, the vegetation of 18 dens of the arctic fox was investigated, as well as reference areas off the dens but in geologically and topographically similar locations. The species composition showed considerable
The integration of risk reduction and climate change adaptation has become an urgent task in addressing increasing urban risk more effectively and efficiently. This paper analyses the extent to which climate change adaptation is integrated into the policies and regulatory frameworks that guide urban risk reduction in Nicaragua, and discusses related progress. The results reveal significant progres
The objective of the present experiments was to study mechanisms governing cerebrovascular responses during severe hypoglycemia, and in the posthypoglycemic recovery period. To that end, lightly anesthetized (70% N2O) and artificially ventilated rats were injected with insulin so as to abolish spontaneous EEG activity for 15 or 30 min ("coma"). In separate animals, recovery was induced by glucose
We tested the hypothesis that populations in small habitat fragments remaining in agricultural landscapes are maintained by repeated immigration, using three grassland butterflies (Aphantopus hyperantus, Coenonympha pamphilus and Maniola jurtina). Transect counts in 12 matched sets of semi-natural pastures, and linear habitat elements proximate and isolated from the pastures showed that population
The neutron beam at the Studsvik facility for boron neutron capture therapy (BNCT) and the validation of the related computational model developed for the MCNP-4B Monte Carlo code are presented. Several measurements performed at the epithermal neutron port used for clinical trials have been made in order to validate the Monte Carlo computational model. The good general agreement between the MCNP c
OBJECTIVES: Despite the recent introduction of new peroral drugs as well as neurosurgical methods for Parkinson's disease, treatment of late stage parkinsonian patients remains difficult and many patients become severely handicapped because of fluctuations in their motor status. Injections and infusions of apomorphine has been suggested as an alternative in the treatment of these patients, but the
