Nanostructures have many material, electronic, and optical properties that are not found in bulk systems and that are relevant for technological applications. For example, nanowires realized from III-V semiconductors can be grown into wurtzite crystal structure. This crystal structure does not naturally exist in bulk where these materials form the zinc-blende counterpart. Being able to concomitant
Older people often have companion animals, and the significance of animals in human lives should be considered by nurses-particularly in relation to older people's health, which can be affected by diseases. The incidence of stroke increases with age and disabilities as a result of stroke are common. This study aimed to explore older people's experiences of living with companion animals after strok
Intestinal barrier function is vital for homeostasis. Conditions where the mucosal barrier is compromised lead to increased plasma content of lipopolysaccharide (LPS). LPS acts on Toll-like receptor 4 (TLR4) and initiates cellular inflammatory responses. TLR4 receptors have been identified on enteric neurons and LPS exposure causes neuronal loss, counteracted by vasoactive intestinal peptide (VIP)
The interaction between the metal organic precursor molecule titanium(IV) isopropoxide (TTIP) and three different surfaces has been studied: Si(111)-(7 x 7), SiOx/Si(111) and TiO2. These surfaces represent the different surface compositions encountered during TTIP mediated TiO2 chemical vapor deposition on Si(111). The surface chemistry of the titanium(IV) isopropoxide precursor and the film growt
The catalytic cycle of multicopper oxidases (MCOs) involves intramolecular electron transfer (IET) from the Cu-T1 copper ion, which is the primary site of the one-electron oxidations of the substrate, to the trinuclear copper cluster (TNC), which is the site of the four-electron reduction of dioxygen to water. In this study we report a detailed characterization of the kinetic and electrochemical p
Pressurized liquid extraction is a "green" technology for the extraction of nutraceuticals from foods and herbal plants. This review discusses the extraction principles and the optimization of the extraction parameters that improves the extraction efficiency. The use of different solvent mixtures and other extraction additives to enhance the efficiency of the extraction are discussed. Dynamic mode
Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Brott på strålbenet på handledsnivå (handledsbrott) är en av de vanligaste orsakerna till att patienter måste uppsöka en akutmottagning. Skadan drabbar oftast medelålders och äldre kvinnor. Skelettet blir skörare hos kvinnor efter klimakteriet, vilket lättare leder till ett benbrott. Medan brott på lårbenshalsen oftast drabABSTRACT Fractures of the distal radius are common injuries that may cause persistent disability and pain. This thesis prospectively investigates the incidence and characteristics of distal radius fractures, the relationship between fracture malunion and disability and the natural course of patient-reported outcome after fracture in a well-defined population in Northeastern Scania, Sweden. Further
We propose two estimators of a monotone spectral density, that are based on the periodogram. These are the isotonic regression of the periodogram and the isotonic regression of the log-periodogram. We derive pointwise limit distribution results for the proposed estimators for short memory linear processes and long memory Gaussian processes and also that the estimators are rate optimal.
The combined data from three fusion-evaporation reaction experiments have been utilized to investigate the semi-magic nucleus Ni-58(28)30. To detect gamma rays in coincidence with evaporated particles, the Ge-detector array Gammasphere was used in conjunction with the charged-particle detectors Microball and LuWuSiA (the Lund Washington University Silicon Array), and a neutron detector array. The
Many trials on Internet-delivered psychological treatments have had problems with nonadherence, but not much is known about the subjective reasons for non-adhering. The aim of this study was to explore participants' experiences of non-adherence to Internet-delivered psychological treatment. Grounded theory was used to analyze data from seven in-depth interviews with persons who had non-adhered to
Energy relay dyes (ERDs) have been investigated previously as a mean to achieve panchromatic spectral response in dye-sensitized solar cells via energy transfer. To reduced the distance between the ERDs and energy-accepting injection dyes (IDs) on the surface of a mesoporous titanium dioxide electrode, the ERDs were immobilized adjacent to the IDs via a sequential functionalization approach. In th
Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multicell, multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can at best only ensure that the desired si
Anthracyclines, e. g. daunorubicin, doxorubicin, and idarubicin, consist of a tetracycline moiety linked via a glycosidic bond to a sugar residue, usually the aminosugar daunosamine. The anthracyclines are efficient chemotherapeutic agents against cancer, but their use is limited due to cardiotoxicity and induction of multidrug resistance. In the search for new anthracycline analogs, a daunosamine
This chapter presents a telehealth system called GiraffPlus supporting independent living of elderly in their own home. GiraffPlus system is a complex system which monitors activities and physiological parameters in the home using a network of sensors. The elaborated information is presented to the primary user, the elderly, and to secondary users like health care and home care providers and possi
The proto-oncogene SKI is highly expressed in human myeloid leukemia and also in murine hematopoietic stem cells. However, its operative relevance in these cells remains elusive. We have over-expressed SKI to define its intrinsic role in hematopoiesis and myeloid neoplasms, which resulted in a robust competitive advantage upon transplantation, a complete dominance of the stem and progenitor compar
One of the main beliefs in quality assurance is that this activity – indirectly – will stimulate change in the work practices associated with teaching and learning in higher education. However, few studies have provided empirical evidence of the existence of such a link. Instead, quality assurance has created an unfortunate divide between formal rules and routines, and the daily practices in acade
Popular Abstract in Swedish Ger en ökad fysisk aktivitet bland växande barn bättre skelett- och muskelutveckling och påverkar det i så fall frakturrisken? Benskörhet och låg benmassa medför en ökad risk för frakturer. Låg fysisk aktivitet är också en riskfaktor. En ökad frakturförekomst är i dag ett växande samhällsproblem, och med dessutom en åldrande population samt en generellt mindre fysiskt Osteoporosis and related fractures are a global health problem. Physical activity, especially during growth, has been suggested as a strategy to improve musculoskeletal health in the population. Previous prospective pediatric exercise intervention studies, however, are short-term, mostly covering less than one year and use bone traits as surrogate endpoints for fractures. The Pediatric Osteoporosi
Sverige har en vision om ”netto-noll” utsläpp av växthusgaser till 2050 och är på god väg att nå utsatta delmål för utsläppsreduktioner till 2020. Klimatfrågan är dock långsiktig och det under klimatkonventionen antagna 2-gradersmålet innebär utsläppsåtaganden som sträcker sig till år 2050 och bortom. En långsiktigt effektiv klimatpolitik ska därför utvärderas både efter vilka långsiktiga utveck
