The Usefulness of Negative Valve Overlap for Gasoline Partially Premixed Combustion, PPC
Partially premixed combustion has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions, even at higher loads. The problem is the ignitability at low load and idle operating conditions. The objective is to investigate the use
Feasibility of neuromuscular training in patients with severe hip or knee OA: The individualized goal-based NEMEX-TJR training program
Background: Although improvements are achieved by general exercise, training to improve sensorimotor control may be needed for people with osteoarthritis (OA). The aim was to apply the principles of neuromuscular training, which have been successfully used in younger and middle-aged patients with knee injuries, to older patients with severe hip or knee OA. We hypothesized that the training program
Symboler i Dalby
Interpretations of the church, monastery and manor of Dalby have focused primarily on the history and functions of the buildings, but symbolic interpretations have been involved too. The article discusses four categories of symbolic interpretations: Power Symbols, Cosmic Symbols, Biblical Symbols and Geographical Symbols. The conclusion is that it is hard, when dealing with specific buildings, to

Synthesis of C-1 indol-3-yl substituted tetrahydroisoquinoline derivatives via a Pictet-Spengler approach
A protocol for the diastereoselective synthesis of C-1 indol-3-yl substituted tetrahydroisoquinoline derivatives via Pictet-Spengler condensation with L-DOPA or L-DOPA derivatives and 1H-indole-3-carbaldehydes is presented. The protocol is used for the successful synthesis of several tetrahydroisoquinolines as well as diketopiperazine fused analogues. (C) 2012 Elsevier Ltd. All rights reserved.
Algebraic Discretization of the Camassa-Holm and Hunter-Saxton Equations
The Camassa-Holm (CH) and Hunter-Saxton (HS) equations have an interpretation as geodesic flow equations on the group of diffeomorphisms, preserving the H-1 and. H-1 right-invariant metrics correspondingly. There is an analogy to the Euler equations in hydrodynamics, which describe geodesic flow for a right-invariant metric on the infinite-dimensional group of diffeomorphisms preserving the volume

Moraxella catarrhalis outer membrane vesicles carry beta-lactamase and promote survival of Streptococcus pneumoniae and Haemophilus influenzae by inactivating amoxicillin.
Moraxella catarrhalis is a common pathogen found in children with upper respiratory tract infections, and in patients with chronic obstructive pulmonary disease during exacerbations. The bacterial species is often isolated together with Streptococcus pneumoniae and Haemophilus influenzae. Outer membrane vesicles (OMV) are released by M. catarrhalis and contain phospholipids, adhesins, and immunomo
Efficient Parallel Solution of Large-Scale Nonlinear Dynamic Optimization Problems
This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and solve the re- sulting nonlinear program using an interior-point algorithm. For this approach, the time to solve the linearized KKT system at each iteration typically dominates the total solution time. In our propo
Search for pair-produced long-lived neutral particles decaying to jets in the ATLAS hadronic calorimeter in pp collisions at root s=8 TeV
The ATLAS detector at the Large Hadron Collider at CERN is used to search for the decay of a scalar boson to a pair of long-lived particles, neutral under the Standard Model gauge group, in 20.3 fb(-1) of data collected in proton-proton collisions at root s = 8 TeV. This search is sensitive to long-lived particles that decay to Standard Model particles producing jets at the outer edge of the ATLAS
Release characteristic of different classes of sodium during combustion of Zhun-Dong coal investigated by laser-induced breakdown spectroscopy
Serious fouling and slagging problems are associated with the combustion of Chinese Zhun-Dong coal due to its high content of sodium (Na). Understanding the release characteristic of Na during the combustion is essential to viable utilization of this coal. In this work, coal samples were treated with a sequence of solvents: water (H2O), ammonium acetate (NH4Ac), hydrochloric acid (HCl), and the re
Ethnic differences in breast cancer risk and survival: A study on immigrants in Sweden
Background. There are large geographic differences in breast cancer risk but whether survival differs between low- and high-risk groups is less well-established. As the survival of cancer depends on the level of healthcare and awareness of disease risks, subtle differences in cancer biology cannot be revealed in international comparisons. Instead, comparison of diverse immigrant groups in a countr
Politik underifrån. Kollektiva aktioner i Sverige och Danmark under 1800- och 1900-talen
This is an introduction to the following essays on collective political action in Sweden and Denmark since 1800. The influence from E P Thompson and Charles Tilly on the historiography is stressed and a remarkable increase in interest in popular protest is noted, especially in Sweden.
Liquid Crystal Phases in Suspensions of Charged Plate-Like Particles
Anisotropic interactions in colloidal suspensions have recently emerged as a route for the design of new soft materials. Nonisotropic particles can form nematic, smectic, hexatic, and columnar liquid crystals. Although the formation of these phases is well rationalized when excluded volume is solely at play, the role of electrostatic interactions still remains unclear and even less so when particl

Adsorption of methylamine on Ni3Al(111) and NiAl(110)-a high resolution photoelectron spectroscopy and density functional theory study
Methylamine adsorption on the ordered Ni3Al(111) and NiAl(110) surfaces has been investigated by high resolution photoelectron spectroscopy and density functional theory calculations. Methylamine adsorbs molecularly at both surfaces at low temperature (90 K). The experiments show that methylamine interacts with the surface aluminium atoms on both surfaces, resulting in a positive binding energy sh

Abstract in French Cette étude vise à mettre en lumière l’acquisition de la liaison préverbale en tant qu’accord sujet-verbe en nombre en français langue étrangère (FLE). Le but principal de l’étude est d’examiner le développement de ce trait morpho-phonologique et d’évaluer l’impact de la fréquence du verbe pour l’emploi de la liaison préverbale en FLE. Nous présentons une étude transversale où 4

Re-evaluation of the conodont Iapetognathus and implications for the base of the Ordovician System GSSP
In 2000, the International Union of Geological Sciences (IUGS) ratified the decision from the International Working Group on the Cambrian–Ordovician Boundary (COBWG) to place the Global boundary Stratotype Section and Point (GSSP) for the base of the Ordovician System in the Green Point section, Newfoundland, Canada, at a point coinciding with the first appearance of the conodont Iapetognathus flu
