A simulation model for convective drying of wet porous materials was developed. For the simulation, we measured the moisture diffusivities within them and applied a modified Dubinin-Astakhov equation to the moisture sorption data for a membrane filter. The simulation results not accounting for internal mass transfer resistance were quite different from the experimental ones. The drying characteris
We present a simple dry release technique which uses a thin fluorocarbon film for efficient removal of plastic microdevices from a mould or a handling substrate by reducing the adhesion between the two. This fluorocarbon film is deposited on the substrate in an advanced Si dry etch device utilising the C4F8 passivation plasma. Micromachined polymer chips made of SU-8 are removed from the handling
Identification of incident myocardial infarction (MI) cases in a defined population using hospital discharge data and mortality data in combination has been suggested. This method of case identification was compared to that of use of MI community registers set up in accordance with principles adopted in a World Health Organization collaborative programme. The comparison comprised data for four Swe
The four major autoantigens (IA-2, IA-2 beta, GAD65 and insulin) of type 1 diabetes are all associated with dense core or synaptic vesicles. This raised the possibility that other secretory vesicle-associated proteins might be targets of the autoimmune response in type 1 diabetes. To test this hypothesis 56 proteins, two-thirds of which are associated with secretory vesicles, were prepared by in v
Patterns of feather wear in birds captured in spring have traditionally been analysed to describe the extent of winter moult in long-distance migrants. However, the interpretation of feather wear may be rendered extremely difficult due to long moult periods, by the progress of the season, and by the existence of complex moult patterns. Here, stable isotope analysis is used to determine the origin
Femtosecond time-resolved two-color four-wave mixing is employed to study the ultrafast excited-state relaxation processes in Ru(tbbpy)(3)(+2). The relaxation processes leading to a long-lived thermalized (MLCT)-M-3-state are found to take place on two distinct time-scales. An ultrafast process, which is attributed to intersystem crossing, rapidly depopulating the initially photoexcited (MLCT)-M-1
Both members of the diploid-tetraploid species pair Anthericum ramosum L. and Anthericum liliago L. occur as geographically disjunct isolates on the margins of their northern range in Scandinavia. Variation in floral morphology was studied in 33 populations of A. ramosum from four geographic regions and 25 populations of A. liliago from seven regions in Scandinavia. Tepal shape was characterized w
Molecularly imprinted nanoparticles were prepared using a simple distillation precipitation polymerization method. In this work, propranolol-imprinted nanoparticles were synthesized using different cross-linkers combined with methacrylic acid (MAA) as a functional monomer in refluxing acetonitrile. Using the new synthetic method, uniform prorpanolol-imprinted nanoparticles were obtained in less th
The novel promoter system IX/AgOTf (X = Cl or Br) has been evaluated in the synthesis of two bislactam analogues of GD3. We have carried out two high-yielding galactosylations in 97% and 98% yield, respectively, using ICl/AgOTf, and four sialylations in 93%, 59%, 40%, and 44% yield, using IBr/AgOTf, The choice of interhalogen (IX) is determined by the donor type used in the glycosylation. We also
Reactive oxygen species (ROS) are important in the immune defense against invading pathogens, but they are also key molecules in the regulation of inflammatory reactions. Low levels of ROS production due to a polymorphism in the neutrophil cytosolic factor 1 (Ncf1) gene are associated with autoimmunity and arthritis severity in mouse models induced with adjuvant. We established an adjuvant-free ar

The Nuclear Renaissance is a term which describes the increased interest in expanding the nuclear power fleet in recent years, after decades of stagnation in the development of new nuclear power plants. Nuclear power has previously met large political resistance, and although this resistance is decreasing, the problem of how to fund new nuclear power plants remains. The thesis investigates whether
Internal social media (ISM) platforms have transformed internal communication by enabling dialogue, participation, and shared meaning-making across organizational hierarchies and locations. While previous research has highlighted ISM’s role in knowledge sharing and employee engagement, less attention has been paid to its function in shaping organizational identity from a managerial perspective.

Cykeltrafikens roll i transportsystem har fått allt större uppmärksamhet på grund av krav på hållbara lösningar för stadsplanering. Utvecklingen av simuleringsmodeller för cykeltrafik är dock fortfarande begränsad jämfört med modeller för motoriserad trafik. Detta arbete undersöker makroskopisk modellering av cykeltrafik med hjälp av PTV Visum, baserat på en litteraturanalys och en fallstudie i LuThe role of bicycle traffic in transport systems has gained growing attention due to demands for sustainable urban planning solutions. However, the development of simulation models for bicycle traffic remains limited compared to motorised traffic models. This thesis investigates the macroscopic modelling of bicycle traffic using PTV Visum with the help of a literature review and a case study in Lu
Background: Mental health is a global public health issue. Mental health disorders can develop in anyone, but the prevalence is higher among refugees. Mental Health and Psychosocial Support (MHPSS), aims to improve mental health and is commonly applied among persons from conflict-afflicted settings such as, refugees. There are several studies demonstrating the effectiveness of MHPSS but there
Solar Energetic Particle (SEP) events, resulting from intense solar eruptions, can trigger significant short-term increases in the production of cosmogenic radionuclides such as 10Be, 14C and 36Cl. This thesis investigates the potential occurrence of SEP events around 14,300 and 14,700 BP, prompted by pronounced excursions previously identified in 10Be and 14C records. To examine these intervals i
