We present a qualitative physical model of the origin of two very brightUV lines of Fe II at 2507-2509 Å, present in high-resolutionspectra of gaseous condensations (blobs) close to the central star ofeta Carinae. The spectra have been obtained with the Hubble SpaceTelescope (HST). The model is based on a type of Bowen mechanism withselective photoexcitation of Fe II by a broad HLyalpha profile,ge
To determine if an inhibition of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH) can counteract the changes in urodynamic parameters and bladder afferent activities induced by intravesical prostaglandin E2 (PGE2 )-instillation, we studied effects of URB937, a peripherally-restricted FAAH inhibitor, on single-unit afferent activity (SAA) during PGE2 -induced bladder overactiv
The development of a model for any energy system is required for proper design, operation or its monitoring. Models based on accurate mathematical expressions for physical processes are mostly useful to understand the actual operation of the plant. However, for large systems like combined heat and power (CHP) plants, such models are usually complex in nature. The estimation of output parameters us
Introduction: Early excision and skin grafting has become the standard of good burn management, but it is associated with major blood loss. Aim: To determine the haemostatic effect of terlipressin compared with placebo. Material and methods: Fifty-one patients with bums of 10-20% total body surface area had early excision and split skin grafting of deep burns. The surface area of the bum wound and
Background: ABO genotyping is complicated by the remarkable diversity at the ABO locus. Recombination or gene conversion between common alleles may lead to hybrids resulting in unexpected ABO phenotypes. Furthermore, numerous mutations associated with weak subgroups and nondeletional null alleles should be considered. All known ABO genotyping methods, however, risk incorrect phenotype predictions
The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths
The first ESR spectroscopic evidence of a bimolecular homolytic substitution (SH2) reaction in a 77 K solid phase was presented, where radicals were substituted for the CH3 group of methylsilane and methylgermane (CH3XD3, X = Si, Ge). The radicals were generated by in situ UV-photolysis of CD3I in the solid CH3XD3 in an ESR cavity at 77 K. Using the selectively deuterium labeled compounds, it was
Inversion recovery (T-1) and microwave power saturation studies have been performed, between 4 and 25 K, on the EPR signal from the stable tyrosyl radical, Y-D(.), in photosystem II core complex preparations from higher plants. Measurements are reported from the dark stable S-1 and first turnover S-2 states of the photosystem catalytic Mn cluster and in two cryoprotectant regimes; sucrose and ethy
ISIS committed mass atrocities against the Yazidis (Kurdish: Êzîdîs) in Sinjar (Kurdish: Şingal), Iraq, in 2014-2017. Several international and regional observers have qualified the acts as genocide under international law. Yet the numerous social, cultural, and political preconditions of the genocide are not recognized in the 1948 Genocide Convention. To answer the line of question, Susan Opotow’
The current patterns of consuming and producing German coffee cause environmental impacts. Identifying the most relevant environmental impacts (hot spots) along the global value chain of German coffee is the first step to improve its environmental performance. Hot spots need immediate attention from companies, practitioners, and scientists in order to create sustainable solutions. The purpose of
In Zambia, the privatisation of state owned companies is challenging job security, working conditions and workers’ rights. It has also weakened the role of government as a regulator of labour legislation, which in Zambia is quite progressive, compared to other countries in the region. Workers struggle to survive and therefore turn to trade unions in order to change their situation. This study exam
The consumption of plastic bags is a global problem that leads to increased concentration of plastic in the world oceans. In 2014, annual consumption of plastic carrier bags amounted to around 100 billion in the EU, which corresponds to an average of about 200 bags per person per year, of which many plastic bags are used only once and/or end up as waste in nature. This thesis is a comparative case
The museum world is in a time of great change, many of the changes focus on the accessibility of museums. In Sweden these changes are becoming more apparent as the new museum law that has been passed advocates for equal museum experience for all visitors whether they have any for of impairment or not. To encourage this change a few older law and regulations that Swedish museums are also subject to
The aim of the present study was to evaluate the risk for vascular morbidity or death and retinopathy in relation to urinary albumin concentration. To that end, we performed a 5-year follow-up study of all type 2 diabetic patients attending the outpatient-clinic. A total of 444 (98.4%) out of 451 adult patients initially studied were evaluated for the degree of retinopathy and levels of HbA1c bloo
BACKGROUND: A previous study has shown that pentoxifylline in combination with vitamin E can reverse radiation-induced fibrosis. The aim of the present study is to investigate if the same drugs could prevent radiation-induced side-effects in women with breast cancer. PATIENTS AND METHODS: A randomised, placebo-controlled, double-blind, parallel group trial was performed. Women with breast cancer w
In this study, we have analyzed the spatial and temporal correlation between the North Atlantic Oscillation (NAO) and the climate in Iraq, with a focus on precipitation, temperature, and number of Mediterranean cyclones. It was found that the influence of the NAO varies per climate indicator. For example, the influence is greater on precipitation than on temperature. One conclusion of the study is
A search is presented for direct top squark pair production using events with at least two leptons including a same-flavour opposite-sign pair with invariant mass consistent with the boson mass, jets tagged as originating from -quarks and missing transverse momentum. The analysis is performed with proton-proton collision data at collected with the ATLAS detector at the LHC in 2012 corresponding to
Objective. New proposed definitions of chronic kidney disease necessitate the development and use of simple and accurate methods for estimating glomerular filtration rate (GFR). Plasma cystatin C has been shown to be a more reliable GFR marker than creatinine and formulae for estimating GFR have been reported. The purpose of this study was to validate a cystatin C-based GFR prediction equation in
