Inverse Synthetic Aperture Radar (ISAR) target images are extracted using compressed sensing methods. The extracted images are edited and merged into measured Synthetic Aperture Radar (SAR) images. A noise free image of the target is extracted from the Radar Cross Section (RCS) measurement by using the Basis Pursuit Denoise (BPDN) method and then solving for a model consisting of point scatterers.

Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. The presence of aquaporins provides the plant with an opportunity to regulate the flux of water between cells and within the cell by changing the abundance or activity of the aquaporins. One aquaporin, PM28A, and two aquaporin

Quantum measurement theory has a peculiar nature with its TWO processes of assertibility, by proof and by measurement, which is beyond formal logic. This two-sortedness with respect to assertibility is discussed in terms of developments of many--sorted logics, sometimes referred to as Logica Magna. Although useful insights are obtained this way, we argue that there is a nonseparability of inferrib

The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. Furt

Popular Abstract in Swedish Om flyttfåglarnas magnetiska orientering Fåglarnas flyttning har fascinerat människan i alla tider och det finns fortfarande många obesvarade frågor om hur fåglarna hittar sina flyttningsvägar. Flyttande fåglar använder olika typer av ledtrådar för att orientera sig. Orienteringexperiment har visat att fåglarna använder information från både himlavalvet och jordens magMy thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. To examine magnetoreception and the function of the light-dependent magnetic compass in birds, I performed behavioural orientation experiments with European robins, Erithacus rubecula, under different spectra and intensities of light. The

Popular Abstract in Swedish Summary in swedish Perinatal dödlighet bland invandrare från Afrikas Horn. Vikten av erfarenhet, rationellt tänkande och traditioner vid riskbedömning av gravida invandrarkvinnor. Avhandlingen visar att barn till kvinnor i invandrargrupper från Afrika söder om Sahara (majoriteten från Somalia och Etiopien), har högre perinatal dödlighet jämfört med barn till svenska kThis thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. After adjustment for risk factors, however, the finding only held true for a subgroup of women from Ethiopia and Somalia (ES). In searching for the mecha

OBJECTIVES: To explore the relationship between genetic background and antibody levels in a nondiabetic population. We evaluated if high levels of autoantibodies against the 65 kDa isoform of glutamic acid decarboxylase (GAD65Ab), were associated with high-risk genes, i.e. HLA, CTLA-4 and INS VNTR genes. DESIGN AND SUBJECTS: Seventy-five (M/F 39/36) subjects exceeding the 95th percentile of GAD65

The clinical pharmacology of desmopressin and a new vasopressin analogue (F992) was investigated in healthy human subjects. The common procedure of overhydration of healthy volunteers when studying the antidiuretic effect of a drug, may affect the pharmacokinetics, in particular the volumes of distribution. Hence, the estimated parameters may not be relevant to euhydrated patients. F992 was found

Popular Abstract in Swedish Medfödda hjärtfel (congenital heart defects,CHD) förekommer hos nästan 1 % av alla födda barn. En del lindriga hjärtfel spontanläker, men de flesta hjärtfel måste opereras i läkande eller lindrande syfte. Stora kirurgiska framsteg har gjorts på senare år. Hjärtfel som tidigare icke ansågs möjliga att åtgärda kan nu opereras, och många operationer utföres tidigt i livet,The aim of this study was to evaluate new MR techniques permitting qualitative and quantitative analysis of cardiac function and measurement of velocity and flow, and later on contrast-enhanced MR angiography, techniques largely unexplored in children with CHD. Infants with tetralogy of Fallot and pulmonary atresia with ventricular septal defect were examined pre-operatively. MRI was found to be a

One of the challenges that must be overcome to realize the practical benefits of ad hoc networks is quality of service (QoS). However, the IEEE 802.11 standard, which undeniably is the most widespread wireless technology of choice for WLANs and ad hoc networks, does not address this issue. In order to support applications with QoS requirements the upcoming IEEE 802.11e standard enhances the origin
