In 1987 we noticed excess adipose tissue in a patient with arm lymphedema and later, objective studies confirmed this clinical finding in patients with non-pitting arm lymphedema following breast cancer. A prospective study was begun in 1993, and its long-term results (15 years) shows overall complete reduction of the excess volume in patients with non-pitting arm lymphedema and that adipose tissu
Configuration management (CM) includes synchronizing and supporting developers in their common development and maintenance of a system. The rapid development of the Internet and time-to-market pressure affects software development. In order to utilize skilled personnel despite geographical location, groups of developers are now working all over the world on the development of common systems, a sit
Arterial cardiovascular disease and neighborhood deprivation are associated. However, no study has determined whether neighborhood deprivation is associated with venous thromboembolism (VTE). We aimed to determine whether there is an association between neighborhood deprivation and hospitalization for VTE, and whether effects vary across sociodemographic groups. The entire Swedish population aged
Popular Abstract in Swedish Även om vi i dagens samhälle försöker minska vårt beroende av förbränningsprocesser är förbränning fortfarande vår största energikälla och förväntas så förbli under en lång tid. Därför är det viktigt att effektivisera förbränningsprocesserna för att maximera den energi som utvinns medan utsläppen samtidigt minimeras. En av de oönskade biprodukterna vid förbränning är soThis work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. By detection of this increased incandescence and analysis of the detected signal, the volume fracti
In this paper, we study the problem of joint permutor analysis and design for J-dimensional multiple turbo codes with J constituent encoders, J>2. The concept of summary distance is extended to multiple permutors of size N and used as the design metric. Using the sphere-packing concept, we prove that the minimum length-2 summary distance (spread) Dmin,2 is asymptoticly upper-bounded by O(N J-1/J).
Recent research and practice have led to the development of relatively complex methods for inquiry which can be applied by human analysts wishing to investigate an organizational problem-space. However, it has appeared until recently that use of these methods could not be supported by software tools, since the limitations of traditional mathematical algorithms constrained their development. In con
Fast and reliable time and frequency synchronization is crucial for packet-based orthogonal frequency division multiplex (OFDM) systems. In this paper we compare and analyze preambles for OFDM systems based on repeated OFDM data symbols or repeated short pseudonoise sequences (PN-sequences). We make an analytical evaluation for AWGN channels and simulate the performance in oneand two-tap Rayleigh
Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concent
The small-disturbance electro-mechanical dynamics of a power system can be translated to an equivalent circuit model with inductances and capacitances. Damping control of active power in proportion to local frequency as with a VSC-HVDC link or an energy storage then corresponds to introducing a resistor in the circuit model. This letter shows that impedance matching can be used to select resistor
Methods for simple and fast detection and differentiation of bacterial species are required, for instance, in medicine, water quality monitoring, and the food industry. Here, we have developed a novel label array method for the counting and differentiation of bacterial species. This method is based on the nonspecific interactions of multiple unstable lanthanide chelates and selected chemicals with
Desulfurization at medium temperature was investigated with focus on impacts of temperature and CO2 concentration under Oxyfuel firing and Regenerative Calcium Cycle (RCC) conditions. Investigation started with thermodynamic analysis and ThermoGravimetric Analysis (TGA). Tests were then conducted by a bench-scale fixed-bed type reactor, using a synthetic gas mixture. Various parameters were evalua
Under appropriate conditions, neural tissues transplanted into the adult mammalian brain can survive, integrate, and function so as to influence the behavior of the host, opening the prospect of repairing neuronal damage, and alleviating symptoms associated with neuronal injury or neurodegenerative disease. Alternative mechanisms of action have been postulated: nonspecific effects of surgery; neur
• Transforming present production and consumption systems towards Circular Economy will require that new models for value provision are devised by companies and accepted by consumers• Numerous factors drive companies towards initiating the shift to more circular material flows• Businesses also face many barriers on their way towards circular business models• There is opportunity space to collectiv
This dissertation deals with design and characterization of functional structures for scattering of electromagnetic waves. An abundance of these structures can be found in nature, such as the structural coloration in the feathers of a peacock, the scales of butterflies and the shell of scarab beetles. Human design of structures providing specific interactions with electromagnetic waves have a long
Disease-modifying treatments remain an unmet medical need in Parkinson's disease (PD). Such treatments can be operationally defined as interventions that slow down the clinical evolution to advanced disease milestones. A treatment may achieve this outcome by either inhibiting primary neurodegenerative events ("neuroprotection") or boosting compensatory and regenerative mechanisms in the brain ("ne
The objective of the present study is the investigation of possibilities for boosting peptide antiinflammatory effects by tryptophan end-tagging, including identification of underlying mechanisms for this. In doing so, effects of tryptophan end-tagging of KYE21 (KYEITTIHNLFRKLTHRLFRR), a peptide derived from heparin co-factor II, on membrane and lipopolysaccharide (LPS) interactions were investiga
This thesis focuses on algorithms and proofs of concepts in the area of wireless systems operating with a large number of antennas, especially at the base station side.The first studied topic concerns the design and implementation of massive multiple-input multiple-output (MIMO) testbeds, primarily for communications. This is an entirely new engineering challenge on its own, due to the unprecedent
