Gas chromatography (GC) and mass spectrometry (MS) were used to determine the stereoisomeric compositions of 6,10,14-trimethylpentadecan-2-ol and 6,10,14-trimethylpentadecan-2-one in wing extracts from 17 Bicyclus butterfly species from different regions of Africa. All samples were purified using solid phase extraction (SPE). Since some species contained both alcohol and ketone, these were separat
This article describes Monte Carlo computer simulations comparing the performances of a conventional neutron three axis spectrometer (TAS) and a micro-TAS, a mu TAS, designed to be as compact as seems practical. The simulations show that the mu TAS delivers performance (intensity at equal resolution) equivalent to that of a normal TAS. The mu TAS should be very cheap to build and a "farm" of sever

This is a short account of Danish history from the viking age until 1658. The Skåne provinces, lost to Sweden in 1658, have often been abscent in Danish histories, and in Sweden, their Danish history is also often forgotten. This books gives them place within a traditional narrative of Danish history.
Information on the density (p) and refractive index m(=n-ik) of elemental carbon (ECa) and organic matter (OMa), the main carbon components of atmospheric aerosols, has frequently been obtained from closure calculations between physical and chemical aerosol properties. However, this approach has suffered from large uncertainties since there were more unknown (or poorly known) parameters than defin
Popular Abstract in Swedish Personlig assistans i praktiken Beredskap, initiativ och vänskaplighet Bakgrund, syfte och perspektivval Denna avhandling handlar om hur det går till att realisera personlig assistans, en insats för människor med omfattande funktionsnedsättningar. Serviceformen personlig assistans, som myntades av den amerikanska Independent Living –rörelsen i slutet av 1960 talet, uPersonal assistance is a user-directed service that was founded by a section of the disability movement, namely the American Independent Living movement, in the late 1960s. Today, the concept and ideology of personal assistance services (PAS) has spread worldwide, and constitutes a part of the support system for people with disabilities in many countries. The service differs from several other pub
A conceptual framework for systematically studying and analysing risk governance is introduced. The framework, which is influenced by design science, is particularly valuable for relating the way risks are handled at the micro-level to aspects at the macro-level. Three central concepts are included in the framework: purpose, function, and form. A function is used to denote what a specific system d
Background: In the setting of primary percutaneous coronary intervention, patients with a chronic total occlusion in a non-infarct related artery were recently identified as a high-risk subgroup. It is unclear whether ST-elevation myocardial infarction patients with a chronic total occlusion in a non-infarct related artery should undergo additional percutaneous coronary intervention of the chronic
Prostate cancer (PCa) is one of the most common cancers in men and is the second leading cause of cancer-related deaths in the USA. In the United States, it is the second most frequently diagnosed cancer after skin cancer, and in Europe it is number one. According to the American Cancer Society, approximately 221,000 men in the United States would be diagnosed with PCa during 2015, and approximate
Laurdan (6-lauroyl-2-dimethylaminonaphthalene) fluorescence spectroscopy has been applied to probe the physical status of the thylakoid membrane upon conversion of violaxanthin to zeaxanthin. So far, only phospholipid-dominated membranes have been studied by this method and hereby we report the first use of laurdan in mono- and digalactosyldiacylglycerol-dominated membrane systems. The generalised
Two-dimensional measurements of primarily hydroperoxyl radicals (HO2) are, for the first time, demonstrated in flames. The measurements are performed in different Bunsen-type premixed flames (H-2/O-2. CH4/O-2, and CH4/air) using photofragmentation laser-induced fluorescence (PF-LIF). Photofragmentation is done by laser radiation at 266 nm, and the generated OH photofragments are probed through flu
Background and purpose Hemiarthroplasty as treatment for femoral neck fractures has increased markedly in Sweden during the last decade. In this prospective observational study, we wanted to identify risk factors for reoperation in modular hemiarthroplasties and to evaluate mortality in this patient group. Patients and methods We assessed 23,509 procedures from the Swedish Hip Arthroplasty Registe

The ALICE Collaboration at the LHC has measured the J/psi and psi' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at root s(NN) = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 mu b(-1). The cross secti
A combination of normal-incidence x-ray standing-wave (NIXSW) spectroscopy, x-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and density-functional theory (DFT) has been used to investigate the interaction of a number of phthalocyanine molecules (specifically, SnPc, PbPc, and CoPc) with the Ag(111) surface. The metal-surface distances predicted by the DFT calculations f
Community-acquired infections, including respiratory tract infections (RTIs) and urinary tract infections (UTIs), represent a major burden for most healthcare systems, partially due to ineffective or inappropriate antibiotic treatment leading to clinical failure, which often requires alternative antibiotics for cure. Appropriate antimicrobial use not only maximises clinical success in the treatmen
In embedded systems, the computing resources are often scarce and several control tasks may have to share the same computer. In this brief, we assume that a set of feedback controllers should be implemented on a single-CPU platform. We study the problem of optimal sampling period assignment, where the goal is to assign sampling rates to the controllers so that the overall control performance is ma
A hollow fiber supported liquid membrane module using one single fiber impregnated with a mixture of 1,10-dibenzyl-1,10-diaza-18-crown-6 and bis(2-ethylhexyl)phosphate dissolved in hexylbenzene was used for passive sampling of ppb levels of Pb(II), Cu(II), Zn(II), Mn(II), Ni(II), and Cd(II) in water. The target ions were simultaneously transported and preconcentrated into a citric acid acceptor so
