We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). A diverse set of process routes will be necessary to produce all intermediates and commercial products. In
While P-wave duration (PWD) is primarily employed to observe the atrial substrate alterations after pulmonary vein isolation (PVI) on atrial fibrillation (AF) patients, the acquired information corresponds to the entire atria. Left (LA) and right atrium (RA), though, may be differently affected by PVI, implying the need for different after-PVI handling. In order to clarify this assumption, five-mi
Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by vasoconstriction and remodeling of the pulmonary vessels. Risk stratification in PAH could potentially be improved by including novel biomarkers related to PAH pathobiology. We aimed to investigate the relationship between extracellular matrix (ECM)-related proteins, survival, and European Society of Cardiology an
We conduct Metropolis Monte Carlo simulations on models of dilute colloidal dispersions, where the particles interact via isotropic potentials of mean force (PMFs) that display a long-ranged repulsion, combined with a short-ranged and narrow attraction. Such systems are known to form anisotropic clusters. There are two main conclusions from this work. First, we demonstrate that the width of the at
Reidite, the high-pressure zircon (ZrSiO4) polymorph, is a diagnostic indicator of impact events. Natural records of reidite are, however, scarce, occurring mainly as micrometer-sized lamellae, granules, and dendrites. Here, we present a unique sequence of shocked zircon grains found within a clast from the Chassenon suevitic breccia (shock stage III) from the ˜200 Ma, 20–50 km wide Rochechouart i
Background: The inverse observational association between body mass index (BMI) and lung cancer risk remains unclear. We assessed whether the association is explained by metabolic aberrations, residual confounding, and within-person variability in smoking, and compared against other smoking-related cancers. Methods: We investigated the association between BMI, and its combination with a metabolic
Background Colorectal cancer is a leading cause of cancer related death worldwide. 20-30 % of patients will develop colorectal liver metastases (CRLMs). Surgical resection is the mainstay of treatment for CRLMs, and is often combined with perioperative chemotherapy, which can prolong progression-free survival after resection. Moreover, observation of CRLMs response to preoperative chemotherapy can
The impact of age and 24-h ambulatory blood pressure (ABPM) on arterial stiffness and carotid intima-media thickness (cIMT) in ischemic stroke patients younger than 60 years of age is poorly explored. A total of 385 acute ischemic stroke patients (aged 49.6±9.7 years, 68% men) were prospectively included and grouped in younger (15–44 years, n = 93) and middle-aged (45–60 years, n = 292). Arterial
Context. Determining the chemical properties of the atmosphere of young forming gas giants might shed light on the location their formation occurred and the mechanisms involved. Aims. Our aim was to detect molecules in the atmosphere of the young forming companion PDS70 b by searching for atmospheric absorption features typical of substellar objects. Methods. We obtained medium-resolution (R ≈ 507
Background: Patients with advanced-stage lung adenocarcinoma (LADC) often develop distant metastases in the skeletal system. Yet, the bone-specific metastasis pattern is still controversial. We, therefore, aimed to examine how the primary tumor location affects bone specificity and survival in LADC patients diagnosed with skeletal metastases. Methods: In total, 209 bone-metastatic Caucasian LADC p
Background: Integrated community case management (CCM) has led to reductions in child mortality in Malawi resulting from illnesses such as malaria, pneumonia, and diarrhea. However, adherence to CCM guidelines is often poor, potentially leading to inappropriate clinical decisions and poor outcomes. We determined the impact of an e-CCM app on the referral, reconsultation, and hospitalization rates
BACKGROUND: Cerebrospinal fluid (CSF) biomarkers are associated with conversion from mild cognitive impairment to Alzheimer's disease (AD), but their predictive value for later end-points has been less evaluated with inconsistent results.OBJECTIVE: We investigated potential relationships between CSF amyloid-β1-42 (Aβ42), phosphorylated tau (P-tau), and total tau (T-tau) with time to nursing home p
Populärvetenskaplig sammanfattningEn stor del av världens energikällor är baserade på förbränning och kan återfinnas i allt från bilar och båtar som drivs av förbränningsmotorer till gasturbiner och kraftverk som används till elproduktion. Den centrala biten inom förbränning är en kemisk omvandling av bränslet då det reagerar med syre till att bilda de två huvudsakliga produkterna, vatten och koldAbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). Their coherent nature allows to perform laser
The leaf volatiles emitted from four nonhost tree species of lps typographus, i.e. Betula pendula, B. pubescens, Populus tremula, and Sambucus nigra, were collected outdoors by headspace sampling in situ and analyzed by GC-MS. Three major classes of compounds, aliphatics [mainly green-leaf volatiles (GLVs)], monoterpenes, and sesquiterpenes, existed in all the deciduous tree species investigated.
The severity of urinary tract infection (UTI) reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU) is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from hos
Since Abney (1987), generative syntax has invested much interest in the structure of the Noun Phrase, producing numerous theoretical as well as descriptive studies. Within the field of Scandinavian Noun Phrase studies, Delsing (1993) was a groundbreaking work that has since been followed up by several important studies, including Vangsnes et al. (2003) and Julien (2005). This field of inquiry is e
Popular Abstract in Swedish Avhandlingen innehåller fyra artiklar som berör olika aspekter av offentlig omfördelning i välfärdsstaten. Avhandlingen syftar till att ge kunskap om konsekvenser av, motiv för och mätande av och denna omfördelning. Den första artikeln ställer frågan: Hög hög skatteomfördelning från arbetande till icke arbetande kan motiveras av grundantagandet att naturresurser är gemThis thesis is an attempt to generate knowledge about the justification, measurement and consequences of public redistribution. The first paper poses the following question: How much redistribution from working to non-working can be justified by arguing that external resources are owned jointly by all, or that ownership should ideally be divided equally? This question is analyzed using bargaining
Popular Abstract in Swedish Populärvetenskaplig sammanfattning av avhandlingen "Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian wetlands". 1980 förde några affärsmän ett okänt antal individer av den sydamerikanska vattensnäckan Pomacea canaliculata till Taiwan. Snäckorna skulle odlas i dammar och säljas som människoföda på marknader i Asien och överskottet skThe South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research h

They are promising for future energy systems, since they are energy efficient, able to use renewable fuels and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases. Various improvements are made during the recent years, however the technology is still in the early phases of
