Today, every new building is constructed with the ambition of it having a very low energy demand or even being completely neutral with regard to supply and demand over a year. In modern low energy or nearly zero energy residential buildings like these, the behaviour of the occupants becomes increasingly more significant in terms of the energy performance of the building. Occupants who are present
In this work we have fabricated and studied hybrid organic-inorganic nanocomposite system formed by gold nanoparticles self-assembled in organic semiconductor thin film - copper tetrafluorophthalocyanine (CuPcF4). By means of Photoelectron Spectroscopy and Transmission Electron Microscopy (TEM) the evolution of the morphology and electronic structure of the system as a function of nominal gold con
Provupparbetning är ett viktigt steg i många metoder för kemisk analys.Detta gäller framförallt fasta prover då de kemiska ämnena som avses för analys, även kallade analyter, måste extraheras ut. Det vill säga att genomföra en överföring av analyter från provet till ett lösningsmedel. Därefter kan halten bestämmas med de metoder som ofta finns till hands i ett analyslaboratorium. I de fall då fettSupercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. The extraction technique is rapid due to the low viscosity and the high diffusivity of analytes in the supercritical extraction phase.The s
The Swedish Navy conducts reconnaissance in an ongoing maritime surveillance operation with ships at sea. This study aims to create a greater understanding of factors for why naval surveillance is not carried out to a greater extent with modern efficient flying reconnaissance sensors to freeing up time for more qualified naval activities. Furthermore, it seeks an increased understanding and whethe
We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (LG0,l) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-pass cell. Beams with orders l=1−3 are generated by a spatial light modulator, which facilitates rapid and precise reconfiguration of the experimental conditions. 180 fs pulses with 610 uJ pulse energy are post-compressed to 44 fs u
Interleukin (IL)-1 family cytokines potently regulate inflammation, with the majority of the IL-1 family proteins being secreted from immune cells via unconventional pathways. In many cases, secretion of IL-1 cytokines appears to be closely coupled to cell death, yet the secretory mechanisms involved remain poorly understood. Here, we studied the secretion of the three best-characterized members o
Spread extrusion (SE), proposed by the first author, is a direct extrusion with spread and without elongation. SE does not change the cross-sections of a workpiece so it may be used for multipass deformation in combination with Twist extrusion (TE). We investigate the plastic flow at the TE and SE. We show that a combination of TE and SE leads to mixing of the metal within the specimen.
Soil is likely the most complex ecosystem on earth. Despite the global importance and extraordinary diversity of soils, they have been notoriously challenging to study. We show how pioneering microfluidic techniques provide new ways of studying soil microbial ecology by allowing simulation and manipulation of chemical conditions and physical structures at the microscale in soil model habitats.The
Aerodynamic performance and energetic savings for flight in ground effect are theoretically maximized during hovering, but have never been directly measured for flying animals. We evaluated flight kinematics, metabolic rates and induced flow velocities for Anna's hummingbirds hovering at heights (relative to wing length R 5.5 cm) of 0.7R, 0.9R, 1.1R, 1.7R, 2.2R and 8R above a solid surface. Flight
Aims Pancreatic β-cells synthesize and release serotonin (5 hydroxytryptamine, 5HT); however, the role of 5HT receptors on glucose stimulated insulin secretion (GSIS) and the mechanisms mediating this function is not fully understood. The aims of this study were to determine the expression profile of 5HT receptors in murine MIN6 β-cells and to examine the effects of pharmacological activation of 5
This contribution seeks to demonstrate how recently developed 3D GIS platforms can help archeologists in relating to the original context legacy data that can be employed to digitally reconstruct the sequence of arbitrary layers as it was observed and then excavated in the end of the nineteenth century. This research has been conducted on the prehistoric cave of Stora Förvar, located on the small
Balance functions have been regarded in the past as a method of investigating the late-stage hadronization found in the presence of a strongly-coupled medium. They are also used to constrain mechanisms of particle production in large and small collision systems. Charge balance functions for inclusive and identified particle pairs are reported as a function of charged particle multiplicity in proto
Glypicans (GPC1-6) are associated with tumorigenic processes and their involvement in neoplastic behavior has been discussed in different cancer types. Here, a cancer-wide GPC expression study, using clinical cancer patient data in The Cancer Genome Atlas, reveals net upregulation of GPC1 and GPC2 in primary solid tumors, whereas GPC3, GPC5 and GPC6 display lowered expression pattern compared to n
In past years, Sweden has been facing a rapid growth of photovoltaic cells, and the total PV installation capacity increased from 300 kW to 1090 MW (2006–2020). The increased number of PV users was a result of active support from the Swedish government with an aim of achieving multiple sustainable goals regarding renewable energy. This project evaluates the profitability of shared PV systems in co
In order to achieve environmental goals, the impact of the European building stock on the environment needs to be reduced through renovation measures. However, regarding heritage buildings, the choice of measure(s) must simultaneously consider the preservation of cultural and historical values. Besides the impact on such values, energy-efficiency measures can result in increased risks for moisture
Purpose: To examine how intellectual property rights holders and intellectual property rights experts view the phenomenon of characters’ copyright expirations. Research questions: How can intellectual property rights holders cope with the expiration of their characters’ copyright? What are the possible implications of copyright expiration for brands? Methodology: The study utilizes an inductive,
Due to the increasing incidence rates of skin cancer, there is an urgent need for novel technologies that can improve diagnostic accuracy and patient outlook. In a previous study, a machine learning model was developed to automatically delineate skin tumours from non-invasive hyperspectral images. However, the reliability of the model was undermined by difficulties with a preprocessing step in whi
Tetra Pak® is a world leading food packaging company with a large variety of paperboard beverage packages. In the development of paperboard packages, an essential component is utilizing simulation models long before physical prototypes are manufactured. This speeds up the development process and allows quick evaluation of new designs. For this to be an effective approach, confidence in the virtual
Konceptet personalisering innebär att fokus allt oftare riktas mot individuella politiker och deras personliga egenskaper. Sociala medier, så som Instagram, har gjort konceptet än mer aktuellt då möjligheterna att politiskt kommunicera personligt har ökat genom dessa. Studien ämnade att undersöka om personaliserad kommunikation av framstående svenska politiker på Instagram har ökat under den senasPersonalisation is a concept which is based on the idea that focus is increasingly directed at the individual politician and his or her personal characteristics. Social media, such as Instagram, has revived the concept since the possibilities for personalised political communication have increased. This study aimed to examine if personalised communication among prominent Swedish politicians on Ins
