Background: Lignocellulosic biomass, such as corn stover, is a potential raw material for ethanol production. One step in the process of producing ethanol from lignocellulose is enzymatic hydrolysis, which produces fermentable sugars from carbohydrates present in the corn stover in the form of cellulose and hemicellulose. A pretreatment step is crucial to achieve efficient conversion of lignocellu
Research in logistics and supply chain management typically considers transport activities between shippers (sender), carriers (transport operators) and customers (recipient). However, a closer look into real-world road freight transport systems reveals more complex constellations involving multiple actors with different functions, leading to a fragmentation of transport planning and control activ
The great polymorphism observed in the major histocompatibility complex (MHC) genes is thought to be maintained by pathogen-mediated selection possibly combined with MHC-disassortative mating, guided by MHC-determined olfactory cues. Here, we partly characterize the MHC class I and II B of the blue petrel, Halobaena caerulea (Procellariiformes), a bird with significant olfactory abilities that liv
The Swedish population-based acute myeloid leukemia registry contains data from 3251 patients (excluding acute promyelocytic leukemia) diagnosed between 1997 and 2006. Informative cytogenetic data from 1893 patients were retrospectively added, including 1054 patients aged between 60 and 79 years. Clonal abnormalities were found in 57% of the informative karyotypes. Karyotypic patterns differed by
Variability in reported histopathology parameters in operated periampullary adenocarcinomas may affect the prognostic weight of the parameters. Standardized axial sectioning produces a higher incidence of involved margins and also seems to produce a lower relative incidence of pancreatic compared with distal bile duct origin and a higher incidence of involved lymph nodes, compared with non-standar
The presence of Fe-bound cyanide ligands in the active site of the proton-reducing enzymes [FeFe]-hydrogenases has led to the hypothesis that such Bronsted-Lowry bases could be protonated during the catalytic cycle, thus implying that hydrogen isocyanide (HNC) might have a relevant role in such crucial microbial metabolic paths. We present a hybrid quantum mechanical/molecular mechanical (QM/MM) s
This study presents a state-of-the-art overview on heat transfer characteristics of fluids (mainly water, carbon dioxide and hydrocarbon fuels) flowing in smooth tubes and enhanced tubes at supercritical pressures and tries to obtain a fundamental understanding of the unique characteristics. Heat transfer in enhanced tubes is much better than that in smooth tubes with a larger pressure drop penalt
Aim: This study investigated the relationship between sexual debut before 14 years of age and socio-demographics, sexual experience, health, experience of child abuse and behaviour at 18 years of age. Methods: A sample of 3432 Swedish high school seniors completed a survey about sexuality, health and abuse at the age of 18. Results: Early debut was positively correlated with risky behaviours, such
Popular Abstract in Swedish Mylonitzonen (MZ) är en kraftigt framträdande rörelsezon i den sydvästra Baltiska urbergskölden (sydvästra Skandinavien) som löper från Varberg i söder till trakterna av Eidsvol (Norge) i norr. Den sammanfogar urbergsblock av olika ålder och ursprung vilka även har skilda geologiska utvecklingshistorier. Öster om zonen, i det s.k. Östra Segmentet (ÖS; delar av Halland, The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), fr
Wild bank voles (Clethrionomys glareolus) may develop diabetes in laboratory captivity. The aim of this study was to test whether bank voles develop type 1 diabetes in association with Ljungan virus. Two groups of bank voles were analyzed for diabetes, pancreas histology, autoantibodies to glutamic acid decarboxylase (GAD65), IA-2, and insulin by standardized radioligand-binding assays as well as
Popular Abstract in Swedish Den främsta orsaken till att cancer kan leda till döden är att tumörceller växer in i angränsande vävnad (invasiv) och tar sig in i blodet eller lymfsystemet och på så sätt sprids (metastaserar) till andra ställen i kroppen och stör funktionen i livsviktiga organ dvs tumören får ett aggressivt växtsätt. Det är därför viktigt, både ur prognostisk och terapeutisk synvinkeThe progressive process of tumour invasion and generation of metastases is the primary cause of death for most patients with cancer. Some of the regulatory components of this progressive process are adhesion, migration, and proteolysis. Urokinase -type plasminogen activator (u-PA) is a serine protease associated with tissue remodelling, cellular invasiveness, matrix degradation, angiogenesis, and
In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means
To obtain knowledge about combustion mechanisms operating in the ammoxidation of toluene, the formation of carbon oxides was studied over a Ti02(B)-supported vanadium oxide catalyst with monolayer loading. The partial pressures of reactants were varied and kinetic rate expressions, completely describing experimental data, were derived. A comparison of the expressions obtained with those for the fo
