The part-load behaviour of combined cycle power plants (CCPP) equipped with post-combustion CO2 capture is analyzed. Different CCPP configurations are compared, including single-, dual- or triple-pressure level steam generators. The gas turbine is a single shaft unit using the variable guide vanes and fuel flow to control the load. The 90% CO2 capture is achieved using monoethanolamine (MEA 30%wt)
In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var
Prostate specific antigen (PSA) in serum has recently been shown to occur in complex with alpha 1-antichymotrypsin and as an approximately 30 kDa. noncomplexed molecular form. We characterized PSA by 3 different assays in samples from 144 patients with benign prostatic hyperplasia (BPH) and 121 with carcinoma of the prostate. One of these noncompetitive assays measured total PSA by detecting PSA c
75 RG2 glioma-carrying Fischer rats were treated by photon activation therapy (PAT) with monochromatic synchrotron radiation and stable thallium. Three groups were treated with thallium in combination with radiation at different energy; immediately below and above the thallium K-edge, and at 50 keV. Three control groups were given irradiation only, thallium only, or no treatment at all. For animal
The present study aims at evaluating the role of protein kinase C (PKC) in the development of acute lung injury, production of inflammatory mediators and expression of adhesion molecules on leukocytes after induction of acute pancreatitis (AP). AP was induced by the intraductal infusion of 5% sodium taurodeoxycholate in the rat. The animals had the PKC inhibitor polymyxin B administered intraperit
Introduction: In the prehospital care of a cold and wet person, early application of adequate insulation is of utmost importance to reduce cold stress, limit body core cooling, and prevent deterioration of the patient’s condition. Most prehospital guidelines on protection against cold recommend the removal of wet clothing prior to insulation, and some also recommend the use of a waterproof vapor b
Abstract In the given report, scientific results gathered at the Alfred- Wegener- Institut für Polar- und Meeresforschung (AWI) within an ScD contract are summarized. The AWI is the German large scale research facility for polar- and marine research. In January 1992 +he new research de- partment at Potsdam has been established with the section Physics und Chemistry of the Atmosphere. 1t coordinate
Frequent loss of heterozygosity in head and neck squamous cell carcinoma (HNSCC) has been found in several chromosomal regions such as 3p, 9p, 11q, 13q and 17p. Fragile histidine triad (FHIT) gene is located at 3p14.2 encompassing a common fragile site, and is identified as a tumor suppressor gene. We examined 57 patients with HNSCC using immunohistochemistry, western blot, and reverse transcripta
Lipoprotein lipase activity in intact epididymal adipose tissue of fasted rats increased rapidly after treatment with insulin in vivo. In contrast, lipoprotein lipase activity in adipocytes isolated from the contralateral fat pads remained essentially unchanged. When adipocytes were incubated for 30 min at ambient temperature in vitro, about 2 times more lipoprotein lipase activity was found in th
In this study I analysed reduplicative ablaut ideophones in English for their morphosyntactical properties, as ideophones in other languages have been found to have several marked characteristics in this respect. Informed by the typology of ideophones in other languages, my research questions were whether the reduplicatives would appear integrated into or outside of sentences, if they would fill f
In the spring of 2015, five young feminist activists were arrested by the Chinese police for allegedly ‘causing trouble’, which resulted in global attention aimed at this new wave of feminist movement. Youth feminist activism have made their voice heard in China through numerous actions for gender equality since 2012. Not much is known about the new feminist movements and the limited work that exi
Larvae from the non-biting midge family Chironomidae have previously been demonstrated to be sensitive to environmental pollution in aquatic environments. Exposure to different contaminants has resulted in an increasing occurrence of deformities of the mouthparts in the larvae. Common pollutions which induce mouthpart deformitys are metals (such as Pb, Zn, Cd, Cu, Hg, Cr, Ni), pesticides and some
In the development of a product or system it is important to know that all the requirements are verified and validated in order to maintain a good reputation and standard. Today ThyssenKrupp Marine Systems AB does not have a clear traceability between requirements and verification. In order to improve and create a clear formal traceability for their developing process a traceability examination ha
The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were
The negative impacts of surface ozone (O(3)) on vegetation are determined by external exposure, leaf gas exchange and plant antioxidant defence capacity, all dependent on climate and CO(2) concentrations. In this study the influence of climate change on simulated stomatal O(3) uptake of a generic crop and a generic deciduous tree at ten European sites was investigated, using the LRTAP Mapping Manu
Phase behavior and structural features were investigated for "complex salts", consisting of the cationic hexadecyltrimethylammonium (CTA) surfactant with polyacrylate (PA(n), n = 30 or 6000) counterions, mixed with water and different n-alcohols (ethanol, butanol, hexanol, octanol, and decanol). The liquid crystalline structures formed were identified by small-angle X-ray scattering measurements,
To identify previously unknown genetic loci associated with fasting glucose concentrations, we examined the leading association signals in ten genome-wide association scans involving a total of 36,610 individuals of European descent. Variants in the gene encoding melatonin receptor 1B (MTNR1B) were consistently associated with fasting glucose across all ten studies. The strongest signal was observ
