I många länder har den här tekniken använts under lång tid medan den i andra är i framåtskridande. Tekniken har använts i Europa sedan början av 1900-talet och är fortfarande en vanlig metod för grundvattenförsArtificial groundwater recharge is an important technology in water resources management and is nowadays one of the most common and rapidly spread world wide methods for increasing groundwater capacity. In many countries this technique has been employed for a long time, however in the others it is in progress. It has been used in Europe since the early 1900s, and is still a popular method municipa

Popular Abstract in Swedish Snabba fenomen, som inträffar efter laserexcitation, har studerats med tidsupplöst röntgendiffraktion (TXRD). I de flesta experimenten har en ljuspuls från en femtosekundlaser använts för att excitera provet, och dynamiken har undersökts med röntgenljus. Tidsupplösta röntgendiffraktionsmätningar har utförts för att studera fasta halvledarmaterial, vätskor, ferro-elektriFast phenomena occurring after laser excitation were studied using time-resolved X-ray diffraction (TXRD). In most experiments, a femtosecond laser pulse was used to excite the sample, and X-rays were used as a probe. The X-ray diffraction technique was used to study bulk semiconductor samples, molten liquids, ferro-electric domain switching in potassium dihydrogen phosphate (KDP), and strain prop

Objective Atrial fibrillation (AF) often progresses from paroxysmal or persistent to more sustained forms, but the rate and predictors of AF progression in clinical practice are not well described. Methods Using the Outcomes Registry for Better Informed Treatment of AF, we analysed the incidence and predictors of progression and tested the discrimination and calibration of the HATCH (hypertension,

Background: Medial plica is a structure with limited understanding of its pathology, but it may be related to the development of medial knee osteoarthritis (OA). We examined the association between medial plica and medial meniscus extrusion (MME), progression of MME, and the risk of early-stage knee OA development in middle-aged persons. Methods: A total of 340 subjects with tibiofemoral Kellgren–

BACKGROUND: We hypothesized that the main barriers to integrating exercise in routine care of patients with chronic kidney disease (CKD) were structural within European healthcare systems rather than due to resistance among healthcare professionals or patients.MATERIALS AND METHODS: This descriptive cross-sectional study used anonymized questionnaires to investigate nurses' and physicians' attitud

A landslide inventory covering the period from 2000 to 2024 was produced using high‑resolution optical imagery. T

Objective-The objective of this study was to determine the conduction properties of the normal atrioventricular (AV) conduction system in relation to accessory pathway (AP) location in patients with symptomatic Wolff-Parkinson-White syndrome. Design-The conduction properties of the AP and the AV node were studied in 356 patients with single manifest AP who underwent successful ablation. Results-Si

Leachate treatment is one of the major environmental issues faced by landfill owners. One promising method for reduction of pollutant discharge is reverse osmosis (RO). RO technology was tested at a pilot plant at Hedeskoga Landfill in southern Sweden. This landfill receives municipal solid waste (MSW) and industrial, commercial and institutional (IC&I) waste, and produces about 3000 m3/ha of

Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol

Popular Abstract in Swedish Ekokardiografisk undersökning av hjärtat utvecklades i Lund i början av 1950 talet av kardiologen Inge Edler tillsammans med fysikern Helmuth Hertz och har under de första 30 åren huvudsakligen utförts via bröstkorgsväggen så kallat transthorakalt ultraljud. Under 1980 talet utvecklades tekniken och man fick instrument som via matstrupen kunde utföra en ekokardiografiskThe subject of this thesis is the clinical use of transesophageal echocardiography (TEE) in patients with stroke or atrial fibrillation. Subjects were examined with echocardiography and sonography of the carotid artery. A control group of randomly selected volunteers without cerebrovascular disease was compared to patients with ischemic stroke. Cardiac pathology was classified as minor potential e

Popular Abstract in Swedish Det finns ett starkt samband mellan en förenings struktur och dess egenskaper. En detaljerad tredimensionell bild av en förenings struktur på molekylnivå är därför grundläggande information för att förstå dess reaktivitet, stabilitet och fysikaliska egenskaper.

Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair
