Onset of cellular flame instability in adiabatic CH4/O-2/CO2 and CH4/air laminar premixed flames stabilized on a flat-flame burner
This paper presents numerical and experimental studies on the onset and evolution of laminar cellular flames of CH4/O-2/CO2 (oxy-fuel) and CH4/air mixtures under adiabatic conditions, stabilized in the proximity of a flat-flame burner at atmospheric pressure. In the numerical simulations, a two-dimensional domain with periodicity at the transverse far field boundaries is resolved using a high accu

Surface science of free standing semiconductor nanowires
Due to the wide range of possible applications, there is a strong current interest in semiconductor nanowires, that began around the start of the millennia. As a result, a number of important new surface science challenges of both fundamental and practical nature have emerged. Surfaces govern important processes for nanowire growth, physical properties and the ability of nanowires to interact with
A search for excited neutrinos in e(-) p collisions at HERA
A search for first generation excited neutrinos is performed using the full e(-) p data sample collected by the HI experiment at HERA at a centre-of-mass energy of 319 GeV, corresponding to a total luminosity of 184 pb(-1). The electroweak decays of excited neutrinos nu* -> nu gamma, v* -> nu Z and nu* -> eW with subsequent hadronic or leptonic decays of the W and Z bosons are considered. No evide
Effect of split fuel injection on heat release and pollutant emissions in partially premixed combustion of PRF70/air/EGR mixtures
Two- and three-dimensional direct numerical simulations are performed to study the combustion process of PRF70/air/exhaust gas mixtures under partially premixed combustion (PPC) conditions relevant to modern low temperature internal combustion engines. The aim is to gain improved understanding of the underlining physics in PPC engines. A skeletal PRF chemical kinetic mechanism is used together wit
Time-resolved X-ray absorption spectroscopy for the study of molecular systems relevant for artificial photosynthesis
Transition metal coordination compounds have a rich photochemistry and are interesting candidates as both light harvesters (photosensitizers) and catalysts in photocatalytic systems. Knowledge of electronic and molecular structure of excited states of photosensitizers and intermediates of catalysts is a key topic for rational design of systems for artificial photosynthesis. We describe recent adva
Bioconversion of industrial hemp to ethanol and methane: The benefits of steam pretreatment and co-production
Several scenarios for ethanol production, methane production (by anaerobic digestion) and co-production of these, using autumn harvested hemp as substrate, were investigated and compared in terms of gross energy output. Steam pretreatment improved the methane production rate compared with mechanical grinding. The methane yield of steam pretreated stems was similar both with and without pre-hydroly
Isolation of human induced pluripotent stem cell-derived dopaminergic progenitors by cell sorting for successful transplantation.
Human induced pluripotent stem cells (iPSCs) can provide a promising source of midbrain dopaminergic (DA) neurons for cell replacement therapy for Parkinson's disease. However, iPSC-derived donor cells inevitably contain tumorigenic or inappropriate cells. Here, we show that human iPSC-derived DA progenitor cells can be efficiently isolated by cell sorting using a floor plate marker, CORIN. We ind
Adsorption of low-density lipoprotein, its oxidation, and subsequent binding of specific recombinant antibodies-an in situ ellipsometric study.
BACKGROUND: Low-density lipoprotein (LDL) particles accumulate in the arterial wall and become oxidized during atherogenesis, leading to the formation of atherosclerotic plaques. The major protein of the LDL particle, apolipoprotein B-100 (apoB-100), becomes fragmented during oxidation and a target for the immune system. METHODS: In this study we used in situ ellipsometry to monitor the adsorption
Topics in Machining with Industrial Robot Manipulators and Optimal Motion Control
Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. The challenge to overcome here is to achieve high-accuracy machining solutions, in spite of the
How to get free will from positive reinforcement
I will start by noting that Harry Frankfurt’s concept of wholeheartedness is in conflict with the intuition that free will should be efficacious in general, rather than pertain only to a small subset of decisions. To replace wholeheartedness I introduce a heuristic account for deliberation and decisions. I will show that introspective activity can lead to the individual having two types ‘introspec
Immune function in a free-living bird varies over the annual cycle, but seasonal patterns differ between years
A central hypothesis of eco-immunology proposes trade-offs between immune defences and competing physiological and behavioural processes, leading to immunological variation within and among annual-cycle stages, as has been revealed for some species. However, few studies have simultaneously investigated patterns of multiple immune indices over the entire annual cycle in free-living birds, and none
Solution and structural studies of the Cd(II) - Aconitate system
The complexing ability of the binary system trans-aconitic acid (H3L) with regard to Cd(II) and the crystal structures of the binary system Cd(II)-(H3L), [Cd3L2(H2O)(6)] n(1) and ternary systems of Cd(II)-(H3L)-Lewis base [Lewis base = 1,10-phenanthroline (2) and 2,2'-bipyridine (3)] have been determined. Compound I is a rare binodal four-connected three-dimensional (3D) metal-organic framework po
New sequence-based data on the relative DNA contents of chromosomes in the normal male and female human diploid genomes for radiation molecular cytogenetics.
ABSTRACT: BACKGROUND: The objective of this work is to obtain the correct relative DNA contents of chromosomes in the normal male and female human diploid genomes for the use at FISH analysis of radiation-induced chromosome aberrations. RESULTS: The relative DNA contents of chromosomes in the male and female human diploid genomes have been calculated from the publicly available international Human
Towards Defence In Depth In Diabetes Glucose Self-Management
Popular Abstract in Swedish Personer med insulinbehandlad diabetes saknar, eller har kraftigt försämrad, kroppsegen förmåga att reglera blodsockernivån genom utsöndring av hormonet insulin, och måste därför ta flera injektioner insulin dagligen. De flesta injektioner tas i samband med måltid, och individen bestämmer normalt sina måltidsdoser utifrån aktuell blodsocker- och hälsostatus i kombinatioDiabetes is a disease characterized by insufficient capacity to regulate the blood glucose level. In insulin-dependent diabetes, multiple daily injections of insulin have to be administered. In-between scheduled visits to the care provider, the patient has to manage the glucose control independently. Insulin dosing is a non-trivial task and many patients find it difficult. This is reflected in the

Chimney grafts in aortic occlusive disease.
The aim of this article was to present juxtavisceral aortic occlusive disease with particular reference to a novel therapeutic approach, namely protected stenting by means of so called chimney grafts. The juxta renal aortic occlusion is the last aortoiliac occlusive lesion not to be stented routinely because of the risk for trash and/or need for overstenting of vital aortic side branches. The risk
HAMLET Forms Annular Oligomers When Deposited with Phospholipid Monolayers
Recently, the anticancer activity of human a-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive native bovine alpha-lactalbumin (BLA) protein. In this study, atomic force microscopy resolved membrane distortions and annular oligomers (AOs) produced by HAMLET when deposited
