In order to investigate and describe the drying kinetics occurring in a porous material during superheated steam drying, a model was developed based on the fundamental transport equations for mass and heat. The driving forces in the model are gradients of moisture, temperature and pressure. The transport coefficients employed were either measured experimentally or were derived theoretically from t
BACKGROUND: Recently, a -168A-->G polymorphism in the MHC class II transactivator gene (MHC2TA) was shown to be associated with increased susceptibility to myocardial infarction (MI). AIM: To confirm the association between the MHC2TA -168A-->G polymorphism and MI and to study its putative role for microalbuminuria, the metabolic syndrome (MetS) and cardiovascular mortality. MATERIALS AND METHODS:
Background and aims: While mechanical parameters (breaking strength, bursting pressure) are used to measure colonic anastomotic healing, reported values are inconsistent. This study developed a novel approach to study colonic anastomotic repair and compared it with mechanical methods. Methods and materials: We created standardized four- and eight-suture colonic anastomoses and performed contrast e
BACKGROUND: Tumor growth and invasiveness occur through infiltration of tumor cells into the host cells and by angiogenesis, which is modulated by proteinases and antiproteinases released from tumor cells that carry out tissue remodelling. A number of studies have revealed variations in the plasma levels of serine proteases and their inhibitors among tumor types. PATIENTS AND METHODS: By immunolog
This study aims to demonstrate the potential of a process-based regional ecosystem model, LPJ-GUESS, driven by climate scenarios generated by a regional climate model system (RCM) to generate predictions useful for assessing effects of climatic and CO2 change on the key ecosystem services of carbon uptake and storage. Scenarios compatible with the A2 and B2 greenhouse gas emission scenarios of the
Prostate cancer is the most common malignancy of men in Western countries. Patients with advanced prostate cancer suffer from incurable bone metastases. Recent data indicate that interactions between prostate cancer cells, osteoblasts, osteoclasts and the bone matrix are essential in the formation of bone metastases. FGF-8 is widely overexpressed in prostate cancer. Recently, FGF-8 has been found
Popular Abstract in Swedish Blodbildningen är en av kroppens livligaste processer. Varje dag bildas det upp mot en triljon (12 nollor!) mogna blodceller. De röda blodkropparna står för transporten av syre, de vita blodkropparna försvarar mot infektioner och trombocyterna deltar i blodlevringen. Bildningen av blodceller sker i benmärgen och kan liknas vid ett träd, där roten utgörs av de så kalladeGranulocyte-macrophage- (GM-) and granulocyte- (G-) colony stimulating factor (CSF) are important cytokines in the regulation of hematopoiesis and for the function of mature blood cells. They are also involved in the cytokine network regulating the inflammatory and immune response. The aim of this study was to investigate the regulation of GM- and G-CSF production at the cellular level. The studie
This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. The resolubilization kinetics was measured through a temperature jump into a droplet microemulsion phase from a two-phase region of microemulsion dr
Non-typeable Haemophilus influenzae (NTHi) is a human pathogen causing diseases in the upper and lower respiratory tract. Otitis media-prone children and adults with cystic fibrosis or chronic obstructive pulmonary disease, are repeatedly infected by NTHi Research in recent years brought to light the entry and survival of NTHi in epithelial cells and macrophages. Their internalization could be a
Popular Abstract in Swedish Avhandlingen utgår från den förändring som ägt rum i Europa det senaste decenniet, med skiftet från ”welfare” till ”workfare” eller aktiveringspolitik. Vissa forskare hävdar att denna politik är den enda möjligheten till inklusion i arbetsmarknaden, för dem som är exkluderade. Andra hävdar att endast den universella välfärdsstaten kan leda till det resultatet. AvhandlinThe thesis aims to discuss if activation policies can support the inclusion of immigrant women and men into the Swedish labour market.A paradigmatic change in welfare policies has taken place in Europe during the last decade with the shift from welfare to workfare or activation policies. Some researchers claim that, for those excluded from the labour force, activation policies are the only way to
Objective: To investigate the first-ever incidence of acute myocardial infarction and stroke in a community based RA cohort compared with the general population. Methods: The RA cohort consisted of all patients in a local RA register in Malmo, Sweden (n = 1022). The patients were recruited from private and hospital based rheumatology practices, and made up the absolute majority of patients with RA
Background: Life expectancy in Sweden is currently one of the longest in the world. The population of Halland has the longest life expectancy in Sweden. Aim: Life expectancy in the province of Halland and Sweden as a whole during 1911-50 was studied and the findings are discussed in the light of local historical data. Method: A trend analysis of risk ratio of death and life expectancy for Halland
The case of Vietnam, represented by the different development paths between Tonkin and Cochin-China, shows the complexity of analysis of the impact of colonialism. Population density was not the organizing principle behind the settlement of French colonialists. Nor did it significantly determine the level of extraction as expected by AJR’s theory. On the contrary, we show that the presence of seve
Poly(arylene ether sulfone)s containing randomly distributed biphenyl units tethered with precisely six imidazolium cations are designed and prepared with the aim to facilitate ionic clustering and conductivity of anion exchange membranes (AEMs). A series of statistical copolymers with different cationic contents are synthesized via K2CO3-mediated polycondensations of 2,2′,3,3′,5,5′-hexamethyl-4,4
We investigate the momentum and energy budget of stellar feedback during different stages of stellar evolution, and study its impact on the interstellar medium (ISM) using simulations of local star-forming regions and galactic disks at the resolution affordable in modern cosmological zoom-in simulations. In particular, we present a novel subgrid model for the momentum injection due to radiation pr
Background: Policy implementation in the context of health systems is generally difficult and the Kenyan health sector situation is not an exception. In 2005, a new health sector strategic plan that outlines the vision and the policy direction of the health sector was launched and during the same year the health sector was allocated a substantial budget increment. On basis of these indications of
During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a
Background Breast-conserving surgery (BCS) followed by radiotherapy (RT) is an established treatment for women with T1-2N0 breast cancers. Since subgroups of patients have low ipsilateral breast tumour recurrence (IBTR) rates, it is important to study whether RT is necessary for all patients. Patients and methods A total of 1187 women with primary T1-2N0M0 breast cancer were randomised, after stan
The aim of present study was to arrange an experimental rabbit model for IgA-nephropathy. To this purpose, an approach was attempted which was previously successfully applied in rabbits, aiming for induction of post-streptococcal glomerulonephritis (PSGN). To induce the nephropathy, we used two Streptococcus pyogenes strains of M4 and M60 serotypes which showed differential IgA-binding capacity me
Understanding why species richness peaks along the Andes is a fundamental question in the study of Neotropical biodiversity. Several biogeographic and diversification scenarios have been proposed in the literature, but there is confusion about the processes underlying each scenario, and assessing their relative contribution is not straightforward. Here, we propose to refine these scenarios into a
