Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. The plant material derived from natural populations in Europe, with special emphasis on the Baltic island of Öland, Sweden. Genetic and mo

This chapter reassesses the modernization processes at work in Republican China during the Warlord period between 1911 and 1927 by focusing on corporate, public action by non-state interest groups and organizations. In particular, it looks at modes of corporate governing at the interface of business/economy and education: the realm of vocational education. The chapter examines a particularly illum

Popular Abstract in Swedish Bröstcancer är den vanligast förekommande cancerformen hos kvinnor. Under sin livstid kommer tio procent av den kvinnliga befolkningen att få bröstcancer men endast en minoritet kommer att avlida av den. Operation är den vanligaste behandlingen och kombineras oftast med strålbehandling. Armlymfödem samt nedsatt axelrörlighet och muskelstyrka är välkända sidoeffekter tilTen percent of the female population in Sweden will be diagnosed with breast cancer during their lifetime, but only a minority will die from the disease. Arm lymph oedema is a well-known complication following breast cancer treatment and the incidence varies between about 10% when axillary node dissection is performed and about 40% when axillary radiotherapy is added. The general aim of this thes

Popular AbstractStudien är ett försök att analysera den sociala konstruktionen av "medievåld" i den svenska pressdebatten 1980-1995. Totalt analyserades 1029 artiklar ur sju av Sveriges största dags- och kvällstidningar. Många artiklar refererar till vetenskapliga "bevis" att våld i medierna föder faktisk aggression. En närmare analys av medieeffektforskningen avslöjar dock att det påstådda sambanThis study is an attempt to analyze the social construction of media violence in the Swedish press debate 1980-1995. Altogether, 1029 articles from seven of Sweden's biggest daily and evening papers were qualitatively analyzed. Numerous claims refer to scientific 'proof' that media violence breeds personal aggression. However, a critical examination of the media effects research reveal that the al

Popular Abstract in Swedish För analys av agroekosystems näringsämnescirkulation presenteras här en generell modell. I centrum står födoproduktionsintensitet, mänsklig bärförmåga, uthållighet och effektivitet. Modellen kan användas på system med flera markanvändningstyper och är därför lämpad för studier i olika skalor. Jämförelser av alla slags agroekosystem, oavsett tid och rum, är möjliga. OlikThis study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. Comparisons of all kinds of agroecosystems, independent of time and place, are made

Prostaglandin E1 has earlier been shown to decrease pulmonary platelet trapping (PPT) following shock. This experiment was performed to evaluate a new method to study PPT in vivo, and to study the effect of prostaglandin E1 and a new antiplatelet drug (ticlopidine) on PPT in rabbits after i.v. administration of endotoxin. Following platelet labeling with In-111, the rabbits were placed under a sci

A new way of preparing catalytically active wire meshes through a thermal-spray technique is described. A metal substrate (e.g. Kanthal AF) was plasma-sprayed with a composite ceramic/polymer-powder. The polymer content of the sprayed layer was burnt off whereupon a well-defined macro-porosity was created. By treating the so obtained material with an alumina-sol the specific surface area could be

I TV-programmet »Uppdrag granskning« påstods nyligen (16 mars 2004) att det är livsviktigt för patienter med akut hjärtinfarkt att bo i närheten av rätt sjukhus. Frågan är när geografiska skillnader i dödlighet blir så pass stora och säkra att de har betydelse för den enskilda patienten. När man studerar skillnader i dödlighet mellan olika sjukhus bör man om möjligt också beakta landstingens roll.It is a known fact that the 1990s brought a decrease in mortality after myocardial infarction in Sweden but that differences in mortality rates following myocardial infarction still remain between the Swedish counties. Unresolved, however, are questions as to what these inter-county differences mean for the individual patient and what role hospital care plays in this context. We analysed all patie

Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors difficult. This thesis has applied microarray-based gene expression and copy-number profiling to STS

Objective: To investigate the association between human herpesviruses and multiple sclerosis ( MS), as well as between measles virus and MS. Methods: The authors identified prospectively collected serum samples from 73 MS cases and retrospective sera from 161 MS cases in two population-based serum bank registers. Analyses of IgG antibody responses in cases and matched referents were performed for

Intestinal alk-SMase (alkaline sphingomyelinase) is an ectoenzyme related to the NPP (nucleotide phosphodiesterase) family. It has five potential N-glycosylation sites and predicated transmembrane domains at both the N- and C-termini. The amino acid residues forming the two metal-binding sites in NPP are conserved, and those of the active core are modified. We examined the functional changes of th

Neutron deficient nuclei near Sn-100 have been produced by fragmentation of a 1 (.) A GeV Sn-112 beam. The fragments were separated, identified and stopped in a highly segmented silicon strip detector stack. This detector measured the total energy of emitted beta(+)-particles. gamma-radiation was measured with surrounding detectors. The half-lives for many nuclides have been determined for the fir

The growth and thermal stability of ultrathin ZrO2 films on the Si-rich Si(0001)-(3 x 3) surface have been explored using photoelectron spectroscopy (PES) and X-ray absorption spectroscopy (XAS). The films were grown in situ by chemical vapor deposition using the zirconium tetra tert-butoxide (ZTB) precursor. The O 1s XAS results show that growth at 400 degrees C yields tetragonal ZrO2. An interfa

Popular Abstract in Swedish Sedan 1981, då de första fallen av AIDS beskrevs, har 25 miljoner människor dött på grund av att de har blivit smittade av immunbristviruset HIV . Det finns idag mer än 40 miljoner människor som lever med HIV eller AIDS. SIV är apsläktets variant på HIV och orsakar normalt ingen sjukdom hos sina värddjur som är olika afrikanska apor, men då asiatiska apor, t. ex. makakeSimian immunodeficiency virus (SIV) infections in macaques are commonly used as models to study the pathogenesis of human immunodeficiency virus (HIV). Both SIV and HIV normally use the CD4 receptor and an additional coreceptor for cell entry. The most common coreceptors used by HIV are CCR5 and CXCR4. SIV use CCR5 and rarely CXCR4 but may use other coreceptors as alternatives. We have studied vi

Glutathione peroxidase (GSHPx) activity, and total and soluble selenium content were compared in five bovine and porcine organs. The highest GSHPx activity in porcine tissues was found in the liver (35.0 U/g), spleen (29.3 U/g) and kidney (27.3 U/g) with much lower values in the heart (1.8 U/g) and diaphragm (0.8 U/g). A different pattern with lower inter-organ variation in GSHPx activity was obse

BACKGROUND: The barrier properties of the gastrointestinal mucosa may be studied by measuring its permeability to different-sized marker molecules. Owing to difficulties in obtaining human tissue it is, however, often necessary to extrapolate findings from experimental animals to man. The aim of the present study was to compare regional intestinal mucosal permeability in man, the rat, and the pig,

Conclusions. The results indicate that SOM of extreme duration, and maybe also the treatment of SOM, are risk factors for developing permanent hearing loss, both conductive and sensorineural. Objective. Fluctuating or persisting hearing loss of varying degrees is known to accompany secretory otitis media ( SOM). The aim of this study was to detect possible hearing sequelae in young adults who had

Allochthonous organic carbon in aquatic systems is metabolized by heterotrophic bacteria, with significant consequences for the biostructure and energy pathways of freshwater ecosystems. The degree to which allochthonous substrates support growth of bacteria is largely dependent on bacterial growth efficiency (BGE), i.e., bacterial production ( BP) per unit of assimilated carbon. Here we show how

Process development, optimization and robustness analysis for chromatographic separation are often entirely based on experimental work and generic knowledge. This paper describes a model-based approach that can be used to am process knowledge and assist in the robustness analysis of an ion-exchange chromatography step using a model-based approach. A kinetic dispersive model, where the steric mass
