The main aim of the present thesis is to demonstrate the efficient quantum memories for light employing coherent processes in rare-earth-ion-doped crystals. Rare-earth (RE) ions between lanthanum, with atomic number 57, and lutetium, with atomic number 71, have a partly filled 4f shell, which is spatially inside the full shells 5s, 5p, and 6s. Therefore, 4f-4f transitions are shielded from environ
Popular Abstract in Swedish Avhandlingen beskriver forskningen kring miniatyriserade enzymreaktorer - nyckelkomponenter i system för diabetsövervakning. Målet är att systemet kontinuerligt och under flera dagar skall kunna mäta glukosstatus hos bäraren. Provtagningstekniken för systemet är mikrodialys; en prob instucken i bukfettvävnaden ger ett prov som innehåller glukos. Analysen av detta proThe development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. The glucose turn-over rate was monitored following a colourimetric assay. The advantage, in terms of high surface
The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”. Implanted bioele
Introduction: Persistent hypertension is a key risk factor for coronary heart disease, stroke and other cardiovascular diseases, such as heart failure. For primary care physicians, hypertension is the number one diagnosis for office visits and for our communities, the treatment of high blood pressure (BP) and its consequences constitutes a substantial economic burden. Aim: To evaluate yoga as a tr
Importance: The 2023 American College of Rheumatology and American Association of Hip and Knee Surgeons Clinical Practice Guideline concluded that obesity alone should not delay joint replacement. Therefore, a substantially increased utilization of joint replacement among patients with obesity could be expected. However, patients with obesity are at increased risk of revision, posing unique challe
Uppsatsen behandlar budpliktsinstitutet i Sverige samt i några andra utvalda länder. Fokus ligger på vilka subjekt som kan drabbas av sanktion, samt vilka typer av sanktioner som finns att tillgå vid ett brott mot sagda budplikt. Institutet har kommit att bli ett av de mer omdiskuterade reglerna på värdepappersmarknaden då det råder osäkerhet om huruvida regeln verkligen passar det svenska företag
Utifrån rättsdogmatisk metod har uppsatsen formulerat vilka de rättsliga definitionerna av nödvärnsrätten och envarsgripande är, problematiserat vilka problem som kan uppstå och var gränserna går. Jag har vidare tittat på samhällsstrukturers uppkomst, härledningar och definitioner. Även vad som är önskvärt och vad konsekvenserna blir när de inte överensstämmer med medborgares allmänna rättsmedvetaBased on legal-judicial methodology, the essay has formulated what the legal definitions of the right of self-defense and citizen’s arrest are, problematized which problems that can arise and where the lines are drawn. I have looked at what is desirable and what the consequences may be when they do not comply with the general publics sense of justice. I have especially looked at the possible emerg
Uppsatsen undersöker om Högsta domstolen (HD), genom att frångå lagstiftarens intentioner avseende vad som ska utgöra normalstraffet för mord, har överskridit sina befogenheter enligt regeringsformen (RF). Med normalstraff avses det straff domstolarna utgår ifrån när det bestämmer straffvärdet. I Sverige utgår all offentlig makt från folket, vilket betecknas som folksuveränitetsprincipen. Det voThe paper examines if the Supreme Court, by not following the legislator´s intentions regarding what the normal penalty for murder should be, has exceeded its powers under the Instrument of Government. Normal penalty refers to the penalty that the courts proceed from when deciding the penal value. The public power in Sweden proceeds from the people. It would be difficult to implement that the pe
Introduction: The knowledge of the diffusion coefficient of a solute in neat carbon dioxide (CO2) and CO2 mixed with organic solvents is of importance as it correlates to the efficiency of chromatography and extraction processes. Background: Several studies have been found in literature for diffusion coefficients measurements of different solutes in neat carbon dioxide, but to our knowledge rather
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
Klimatet har varit relativt stabilt under den nuvarande interglaciala epoken (Holocen) som inleddes för ungefär 11 700 år sedan. Genom klimatrekonstruktioner från olika geologiska arkiv såsom iskärnor, sjösediment och torvmossar har det ändå påvisats att snabba förändringar i klimatet har inträffat under denna epok. En sådan tidsperiod inträffade för omkring 2800 år sedan och den är intressant ur Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. There are, however, indications for a global extent of the climate change. The climate change coincides with a distinct increas
The joint Swedish-Russian “Tundra Ecology-94” expedition during 1994 used the large Russian ice-breaking research vessel R/V Akademik Fedorov a platform and went along a coastline of 3500 km-from the Kola Peninsula 10°E to Kolyuchinskaya Bay 173°E. Radioactivity in air, seawater and sediment was explored at various locations along the route. The average of 7Be activity concentration in air over th

The aim also was to investigate what nursing care needs there were in men with prostate cancer and how these were met
Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ
Mycoprotein from the fungi Fusarium Venenatum A3/5 has been used as a meat alternative for a long time but little attention has been paid to the waste it creates. When the fungi is fermenting it uses a lot of water which is sent to the drain after the process is finished. This water contains large quantities of both nutrients and biomass. As circular economy is becoming more important for environm
In Bhutan, post-harvest losses are a significant challenge for many small scale farmers, especially in rural areas. Since these losses impact the ability to preserve foods during the peak harvesting seasons, this has a wide range of consequences, both for the farmers themselves and for the country as a whole. It contributes to food insecurity, economic uncertainty and the nutritional deficiencies

Background: Randomized trials have demonstrated that early anticoagulation after acute atrial fibrillation-associated ischemic stroke is safe and non-inferior to delayed initiation. Whether anticoagulation should be delayed in people with larger infarcts is uncertain. Aims: To investigate whether ischemic stroke infarct volume, measured precisely by segmentation, modifies the treatment effect of e
Den skatterättsliga särregleringen av fåmansföretag har allt sedan dess tillkomst år 1976 varit föremål för stark kritik. Regelsystemet har bland annat kritiserats på den grunden att den stränga beskattningen får en negativ inverkan på den svenska företagsamheten och tillväxten. Skälen för en särreglering, främst upprätthållandet av de skatterättsliga neutralitets- och likformighetsprinciperna, ha
