Popular Abstract in Swedish Senare års forskning har klart och entydigt pekat på njurens viktiga roll i utvecklingen av högt blodtryck. Det är mycket sannolikt att det föreligger flera av varandra oberoende mekanismer som förklarar uppkomsten av högt blodtryck, men det är möjligt att flera av dessa, på en organfysiologisk, cellfysiologisk eller genetisk nivå kan ha gemensamma patofysiologiska länkStudies were conducted to investigate the role of macula densa (MD)-derived nitric oxide (NO) in regulation of the glomerular filtration (GFR) through the tubuloglomerular feedback (TGF) mechanism. Immunocytochemical localization of the neuronal isoform of NO synthase (NOS) in the kidney showed that this isoform was exclusively located in MD cells. Whole kidney clearance measurements of GFR and mi

Popular Abstract in Swedish Kan immunförsvaret orsaka ledsjukdomar? Ett väl fungerande immunsystem är en förutsättning för att kroppen ska kunna bekämpa diverse sjukdomar orsakade av t. ex. virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att kunna skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Man tror att vissa sjukdomar, så kalCollagen-induced arthritis (CIA) is a mouse model for rheumatoid arthritis, in which autoimmunity is induced by immunization with type II collagen (CII), a cartilage-specific protein. In the present work, alpha/beta T cells were shown to be required for CIA and for the production of anti-CII IgG antibodies, whereas gamma/delta T cells were neither necessary nor sufficient for development of CIA. A

The paper presents sufficient and almost necessary conditions for the presence of periodic solutions for zero dynamics of virtually constrained under-actuated Euler-Lagrange system. This result is further extended to detect periodic solutions for a class of hybrid systems in the plane and analyze their orbital stability and instability. Illustrative examples are given.

Popular Abstract in Swedish Aerob kapacitet, i dagligt tal konditionen, är den maximala förmågan att utföra ett fysiskt arbete karaktäriserat av den maximala syreförbrukningen (V'O2max). Detta maximala arbete kan endast utföras en begränsad tid, till stor del beroende på en tilltagande anaerob metabolism, vilken bl.a. avspeglas som en ökning av utvädrat CO2 i lungorna. Längre tids arbete kan emellDifferent methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. Comparison of the rating with an exercise test in a group of women revealed that a correction based on age more accurately predicted the maximal exercise capacity. An

In Scandinavian, nominal phrases can contain constituents that look like possessors without having a possessor theta role. These constituents, which I call pseudopossessors, come in three types: swearword pseudopossessors, measure pseudopossessors, and characterising pseudopossessors. I argue in this paper that pseudopossessors are -s-marked constituents that are located in the adjectival field in

Detta är introduktionskapitet till rapporten "DigiTrust: Tillit i det digitala. Tvärvetenskapliga perspektiv från ett forskningsprojekt", där forskargruppsledarna beskriver grunderna för projektet.

Denna avhandling handlar om teoretisk partikelfysik. Partikelfysik handlar om elementarpartiklar och hur dessa växelverkar med varandra, dvs vilka krafter som verkar mellan dem. Detta är hur materien ser ut på den minsta skala vi har kunnat studera experimentellt. Den teori som beskriver de starka, svaga och elektromagnetiska krafterna och de materiepartiklar som vi känner till, kvarkar och leptonThis thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. We wrote their effective field theories in a very similar way so that the calcul

Human activity is constantly causing environmental problems due to production and release of numerous chemicals. A group of compounds of special concern is persistent organic pollutants (POP). These toxic, lipophilic chemicals have a high chemical and biological stability, and tend to accumulate in the lipid phase of living organisms. A major sink for POPs are sediments, and consequently these are

Popular Abstract in English In our society powder is found to be a common state of material. Indeed, the powder state is found to be convenient to store and transport large quantities of material. One of the major techniques to produce powder is spray drying, also for thermally sensitive materials such as foods and pharmaceuticals. In spray drying a liquid is vaporized into a hot air stream, whichSpray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. Even though spray drying is a well-established method to produce dry powder numerous challe

The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. These approaches often lead to satisfactory results, but they could be augment

We discuss the use of the Mechatronics Control Kit from Mechatronic Systems, Inc. for control education and research. The Mechatronics Control Kit can be configured with several distinct plants, including a simple DC motor, an inertia wheel pendulum and a Pendubot. The digital electronics are fully integrated and include a Texas Instruments DSP development system, the TMS320C6711 DSK Board (a DSP

Som tonsättare upplevde jag starkt skillnaden av att komma från konsertsalen till operasalongen. I konsertsalen står det autonoma verket i fokus, men i operasalongen är det handlingen. Dessutom var skillnaden påtaglig i att planera ett verk inom ett konsertprogram för mindre än 100 lyssnare till att tänka sig 1000 lyssnare och att man ensam ska fånga intresset en hel kväll. I min konstnärliga avha
