Concepts are the basic building blocks of all knowledge, while the strength of the theories that guide any societal project is dependent on the quality those concepts. Contrarily, the utilization of questionable concepts will result in questionable material effects. As two of the oldest geographical concepts still in widespread use, ‘rural’ and ‘urban’ stand in stark contrast to the immense change
Magnetic relaxation dispersion measurements have been performed on aqueous protein solutions to study the dynamics of waters in the proton transport channel of bacteriorhodopsin and the self-association of the proteins BPTI, lysozyme and beta-lactoglobulin. The measurements have focused on the bulk relaxation rates, R1 and R2, of three water nuclei 1H, 2H and 17O that are coupled to the protein en
Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. Our results indicated that lymphocytes had significantly prolonged half life after in vivo supplementation with
Defining, prioritizing, and selecting requirements are problems of tremendous importance. In this paper, a new approach called Quantitative WinWin for decision support in requirements negotiation is studied. The difference to Boehm's WinWin groupware-based negotiation support is the inclusion of quantitative methods as a backbone for better and more objective decisions. Like Boehm's original WinWi
Preschool children's learning isthe subject of this study. Three children aged 4, 5 and 6 participated. The data consist of individual interviews with the children before and after the intervention and a videotaped intervention. Our results show that children seem to see a whole as something that is not cut into pieces, no matter what it looks like. They do not necessarily refer to the whole when
Background: The standard reference region (RR) for amyloid-beta (Aβ) PET studies is the cerebellar grey matter (GMCB), while alternative RRs have mostly been utilized without prior validation against the gold standard. This study compared five commonly used RRs to gold standard plasma input-based quantification using the GMCB. Methods: Thirteen subjects from a test–retest (TRT) study and 30 from a
Massive multiple-input multiple-out (MIMO) technology is vital in millimeter-wave (mmWave) bands to obtain large array gains. However, there are practical challenges, such as high hardware cost and power consumption in such systems. A promising solution to these problems is to adopt a hybrid beamforming architecture. This architecture has a much lower number of transceiver (TRx) chains than the to
Context. Next to H and He, carbon is, together with oxygen, the most abundant element in the Universe and widely used when modelling the formation and evolution of galaxies and their stellar populations. For the Milky Way bulge, there are currently essentially no measurements of carbon in un-evolved stars, hampering our abilities to properly compare Galactic chemical evolution models to observatio
Popular Abstract in Swedish Marsupialia (pungdjur) delas in i 280 nu levande arter, som är uppdelade i 19 familjer och sju ordningar. Släktskapet mellan de sju ordningarna har studerats på molekylär nivå på grundval av mitokondriella genom som sekvenserats i sin helhet. Pungdjur, jämte placentala (moderkaks-) däggdjur och kloakdjur, utgör de nu levande representanterna för klassen däggdjur. PungdjThe relationships of the mammalian infraclass Marsupialia have been investigated by phylogenetic analysis using completely sequenced mitochondrial genomes. The organisation and structure of the marsupial mitochondrial genomes deviates from the general mammalian structure. Several features, not known from other mammalian mitochondrial genomes have been shown to be present in all seven living marsup
In the present study the nature of stress and coping was investigated and considered as socially constructed. Thirty small group interviews were performed using the Critical Incident Technique in one female- and one male-dominated customer service department of a telecom company. The main themes about stress among both women and men were often expressed as collective phenomena and were connected t
One of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. The large amount of experimental work and reluctance for changing existing processes has caused the pharmaceut
Homogeneous Charge Compression Ignition (HCCI) holds great promises for good fuel economy and low emissions of NOdx and soot. The concept of HCCI is premixed combustion of a highly diluted mixture. The dilution limits the combustion temperature and thus prevents extensive NOdx production. Load is controlled by altering the quality of the charge, rather than the quantity. No throttling together wit
Importance: We know little about the transmission of obsessive-compulsive disorder (OCD) across generations. Objective: To evaluate the sources of parent-offspring transmission of OCD and familial cross-generational association with more typical anxiety disorders. Design, Setting, and Participants: This Swedish population register-based study analyzed data for offspring born in Sweden from 1960 to
Popular Abstract in Swedish I Sverige analyseras omkring 40 000 DNA-prover från brottsplatser varje år. DNA-profilerna jämförs mot DNA-profiler från misstänkta personer och kan på så vis användas för att knyta en person till ett brott. Alla typer av kroppsvävnader kan analyseras, såsom blod, saliv och hudceller. Vanliga bevismaterial är cigarettfimpar, flaskor, burkar och kläder. De material som cDNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. In this work, pre-PCR processing was applied to improve
Popular Abstract in Swedish Föreliggande arbetes övergripande syfte är att visa på faktorer/begrepp viktiga för en motiverande grundskolemiljö med fokus på klassrummet då analysen baseras på läroplansmålsättningar. Mer differentierade och explicit uttryckta syften för detta arbete utgörs inledningsvis av att dels undersöka hur elever och skolledare uppfattar att skolan uppnått målen i läroplan förThe prime purpose of the work in hand is to present factors/concepts important in generating a motivating environment in our compulsory school system, with a focus on the classroom, the analysis being based on the goals stated in the national curriculum. Expressed in greater and more explicit detail, the purpose of this study was initially to a)investigate how pupils and school principals perceive
Popular Abstract in Swedish Summary in Swedish Populärvetenskaplig sammanfattning Neuroblastom uppstår ur omogna nervceller i binjurarna eller i nervvävnaden bredvid ryggraden och är den vanligaste extrakraniala solida tumörformen hos barn. Varje år drabbas ca 10-15 barn i Sverige och sjukdomen uppkommer vanligast hos barn under 4 år. Trots enorma framgångar med behandlingsformer, så som cytostatAbstract Neuroblastoma is a highly malignant neoplasm found in children. Although children with high-risk neuroblastoma respond to chemotherapy, relapses are common and an estimated long-time survival prognosis is approximately 15%. Thus, there is a tremendous need for new chemotherapeutic drugs for the treatment for neuroblastoma. Polyamines are needed for cell proliferation and cell survival. Th

This paper was written in an attempt to study a less researched area of Swedish development aid and its effort to help build institutions in developing countries. Our purpose is to examine to which extent the practice of “twinning” - exchange projects between equivalent or similar government agencies in different countries - can lead to institutional development. We have interviewed five Swedish a
