New halogen-specific detector applied to the analysis of chlorinated fatty acids
A new halogen-specific detection method (XSD) was tested for determination of chlorinated fatty acids in marine biota. In XSD, an increased emission of ions and electrons is caused by the high-temperature combustion of halogen-containing compounds. The detection limit of methyl dichlorooctadecanoate and the selectivity at a reactor temperature of 900 degreesC match those of electrolytic conductivi

Metoder att välja korrektioner vid fuktberäkningar med variabelt utomhusklimat
Popular Abstract in SwedishMånga skador och olägenheter av fukt kan uppkomma under en byggnads livslängd. De kan t.ex. orsaka hälsoproblem eller dålig ekonomi. För att minska fuktproblem kan en fuktdimensionering göras. I en fuktdimensionering behövs olika fuktberäkningar för att se hur fukttillståndet förväntas bli i eller på en yta av en konstruktion. Beräknade fukttillstånd används för att kontDetermination of the design conditions for moisture resistance requires in a Moisture Design number of different moisture calculations to be made in order to determine the moisture status within, or on the surface of, a structure. The objective of this work has been to ascertain how to allow for variations in climate data in order to be able to determine the most unfavourable moisture status likel
Selective pressurized liquid extraction of polychlorinated dibenzo-p-dioxins, dibenzofurans and dioxin-like polychlorinated biphenyls from food and feed samples
Selective pressurized liquid extraction (PLE) of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) from various food and feed samples was performed with a selective PLE method previously developed for bulk PCBs. The method utilizes sulfuric acid impregnated silica inside the extraction cell to oxidize coextracted fat. Extractions were per
Femoral neck geometry and radiographic signs of osteoporosis as predictors of hip fracture
A total of 125 consecutive hip fracture patients were investigated regarding hip geometry. There were 33 men of mean age 76 +/- 10 years, and 92 women of mean age 78 +/- 9 years. Patients with previous hip surgery were excluded. Hip geometry (hip-axis length, width of collum femoris, and femoral shaft and neck-shaft angle) were registered on both plain radiographs and DEXA scans performed within 2
Celecoxib 200 mg q.d. is efficacious in the management of osteoarthritis of the knee or hip regardless of the time of dosing
Objectives. The primary objective was to demonstrate equivalence between a.m. and p.m. dosing of celecoxib 200 mg q.d. An equivalence assessment of q.d. vs b.i.d. dosing was a secondary objective. Methods. In this randomized, double-blind study, patients with symptomatic osteoarthritis of the knee or hip were randomized to receive celecoxib 200 mg q.d. a.m., celecoxib 200 mg q.d. p.m. or celecoxib
Physiotherapy as a promoter of sexual health.
Despite the holistic intention of physiotherapy, sexual health receives insufficient attention by physiotherapists. Sexual health is an important part of general health and well-being, which is often negatively affected by physical and psychological disorders. There are several reasons why sexual health should be addressed by physiotherapists, and this article aims to describe the role of the phys
Experimental and theoretical study of the ground-state M1 transition in Ag-like tungsten
We present an experimental and theoretical study of the F-2(5/2) -> F-2(7/2) M1 transition in Ag-like W (W27+). The experiments employed the Shanghai permanent magnet electron beam ion trap, which has been developed especially for assisting spectroscopic diagnostics of edge plasmas for magnetic fusion devices. The theoretical value was obtained using the GRASP2K set of computer codes and included
A palynological study from Sweden reveals stable terrestrial environments during Late Silurian extreme marine conditions
A palynological study of the upper Silurian Oved-Ramsasa Group in Skane, Sweden yields a well preserved spore assemblage with low relative abundances of marine microfossils. In total, 26 spore taxa represented by 15 genera were identified. The spore assemblage is dominated by long-ranging cryptospore taxa, and the trilete spore Ambitisporites avitus-dilutus. However, key-species identified include
Fruit and vegetable intake and cause-specific mortality in the EPIC study
Consumption of fruits and vegetables is associated with a lower overall mortality. The aim of this study was to identify causes of death through which this association is established. More than 450,000 participants from the European Prospective Investigation into Cancer and Nutrition study were included, of which 25,682 were reported deceased after 13 years of follow-up. Information on lifestyle,
Antimicrobial effects of helix D-derived peptides of human antithrombin III.
Antithrombin III (ATIII) is a key antiproteinase involved in blood coagulation. Previous investigations have shown that ATIII is degraded by Staphylococcus aureus V8 protease, leading to release of heparin binding fragments derived from its D helix. As heparin binding and antimicrobial activity of peptides frequently overlap, we here set out to explore possible antibacterial effects of intact and
Atherosclerosis: cell biology and lipoproteins.
Low production of reactive oxygen species in granulocytes is associated with organ damage in systemic lupus erythematosus
Introduction: Polymorphonuclear leukocytes (PMN) are main effector cells in the acute immune response. While the specific role of PMN in systemic lupus erythematosus (SLE) and autoimmunity is still unclear, their importance in chronic inflammation is gaining more attention. Here we investigate aspects of function, bone marrow release and activation of PMN in patients with SLE. Methods: The followi
Anti-browsing effects of birch bark extract on fallow deer
A major problem within forest industry is unwanted browsing on seedlings from mammalian herbivores. The aim of this study was to evaluate the effects of birch bark extracts as repellents towards fallow deer. Birch bark was extracted in a conventional way with ethanol as solvent at ambient temperature and with a new method, liquid CO2 extraction. An analysis of the ethanol-extracted birch bark show
The role of AIB1 and PAX2 in primary breast cancer: validation of AIB1 as a negative prognostic factor.
BackgroundThe steroid-receptor coactivator amplified in breast cancer one (AIB1) is implicated to be a prognostic factor, although the results are not unanimous. Recently its effect was suggested to be modified by paired box 2 gene product (PAX2).Patients and methodsUsing immunohistochemistry (IHC) AIB1 and PAX2 were investigated in two cohorts of early breast cancer, including systemically untrea
Biotic dynamics and carbonate microfacies of the conspicuous Darriwilian (Middle Ordovician) 'Taljsten' interval, south-central Sweden
Enclosed in the Darriwilian (Middle Ordovician) part of the reddish 'orthoceratite limestone' of Baltoscandia is a conspicuous c. 1.5 m thick unit colloquially known as the 'Taljsten' interval. It has a wide geographical distribution in the Baltoscandian paleocontinent but is particularly well exposed in south-central Sweden. The unit is characterized by its deviant gray color and beds with a mass
Bit-Serial CORDIC: Architecture and Implementation Improvements
Abstract in UndeterminedThis paper presents a new and improved bit-serial CORDIC architecture. A detailed description of the bit-serial implementation and its Control Unit is presented. It is shown that the improvement is due to a reduction of registers in the implementation and is made possible by ensuring that the angular path is calculated prior to the corresponding vector paths. In addition, t
A trade-off between perceived predation risk and energy conservation revealed by an immune challenge experiment
Energy is typically a limiting factor for animals during boreal zone winters, when low temperatures increase the cost of thermoregulation at the same times as short day-lengths and snow cover constrain foraging opportunities. Under these circumstances animals use a suite of behavioural and physiological adaptations to avoid overnight starvation. However, it is poorly understood how such strategies
Pan-vertebrate comparative genomics unmasks retrovirus macroevolution.
Although extensive research has demonstrated host-retrovirus microevolutionary dynamics, it has been difficult to gain a deeper understanding of the macroevolutionary patterns of host-retrovirus interactions. Here we use recent technological advances to infer broad patterns in retroviral diversity, evolution, and host-virus relationships by using a large-scale phylogenomic approach using endogenou
