Characterisation and application of portable solar absorption spectrometers for the detection of greenhouse gas emissions from regional anthropogenic sources
In der vorliegenden Arbeit wurde im Rahmen des kĂŒrzlich vom Karlsruher Institut fĂŒr Technologie (KIT) etablierten Collaborative Carbon Column Observing Network (COCCON) eine umfassende Kalibrierungsprozedur fĂŒr ein mobiles Fourier-Transformations-Infrarotspektrometer (EM27/SUN) entwickelt. ZusĂ€tzlich wurde die LangzeitstabilitĂ€t des EM27/SUN untersucht. Zudem wurde ein Ensemble dieser Spektrometer genutzt, um lokale Emissionen starker Emitter der wichtigsten Treibhausgase Kohlenstoffdioxid (CO2) und Methan (CH4) zu quantifizieren.
Die Sicherstellung hochgenauer und prĂ€ziser CO2 und CH4 Messungen ist Ă€uĂerst wichtig fĂŒr die Detektion lokaler Quellen dieser Gase. Selbst eine GroĂstadt bewirkt nur eine Erhöhung der entlang des Sehstrahles gemittelten CO2-Konzentration im Promillebereich ĂŒber dem atmosphĂ€rischen Hintergrund. Verglichen mit der nationalen Skala sind Unsicherheiten von lokalen CO2- und CH4-Emissionen gröĂer. Genaue Messungen von lokalen Quellen, speziell StĂ€dten, sind daher wichtig fĂŒr die Verifizierung von weltweiten Zielen zur Reduktion von Treibhausgasen.
Im ersten Teil der Arbeit wurde eine standardisierte Kalibrierungsroutine fĂŒr EM27/SUN Spektrometer entwickelt. Diese beinhaltet eine Optimierung der optischen Ausrichtung des Spektrometers, Labormessungen fĂŒr die Charakterisierung der instrumentellen Linienform und atmosphĂ€rische Vergleichsmessungen mit einem Referenz-EM27/SUN. Mittels dieser Kalibrierungsprozedur wurden zwischen 2014 und 2018 30 EM27/SUN Spektrometer am KIT justiert und ĂŒberprĂŒft, was zu sehr einheitlichen Charakteristika der Spektrometer fĂŒhrte. Aufgrund einer engen Zusammenarbeit mit dem Hersteller der EM27/SUN werden neue Spektrometer seit kurzem routinemĂ€Ăig am KIT ĂŒberprĂŒft, bevor sie zu Arbeitsgruppen weltweit ausgeliefert werden. In einer dreieinhalbjĂ€hrigen Studie wurde auĂerdem die LangzeitstabilitĂ€t des EM27/SUN gegenĂŒber einem Referenzspektrometer untersucht. Es konnte gezeigt werden, dass das EM27/SUN auf einer Zeitskala von mehreren Jahren stabil ist.
Im zweiten Teil dieser Arbeit wurden mehrere EM27/SUN verwendet, um CO2- und CH4-EmissionsstĂ€rken von GroĂstĂ€dten zu quantifizieren. In einer ersten Kampagne, durchgefĂŒhrt in Berlin im Juni und Juli 2014, wurden die Messungen mit einem Dispersionsmodell verglichen. Die beobachteten CO2-Signale sind mit einer GesamtemissionsstĂ€rke der Stadt Berlin von 800 kg CO2 / s vertrĂ€glich.
In einer zweiten Kampagne in Paris im April und Mai 2015 wurde mithilfe der Messungen ein bestehendes Emissionsinventar fĂŒr den GroĂraum Paris zusammen mit dem Chemie-Transport-Modell CHIMERE verifiziert. Dabei wurde herausgefunden, dass die Emissionen im Ostteil der Stadt vom Modell unterschĂ€tzt werden. Im Gegensatz zu Berlin wurden fĂŒr Paris auĂerdem signifikante CH4-Konzentrationsgradienten detektiert.
In einer dritten Kampagne, durchgefĂŒhrt im GroĂraum Tokyo von Februar bis April 2016, wurden CO2- und CH4-Konzentrationsgradienten gemessen, die deutlich ĂŒber den fĂŒr Paris und Berlin ermittelten Werten liegen. Die berechnete CO2-EmissionsstĂ€rke zwischen Tokyo und Paris skaliert mit der Einwohnerzahl.
Die Ergebnisse dieser Arbeit werden helfen, die Reduktionsziele fĂŒr Treibhausgase zu ĂŒberprĂŒfen, wie sie von internationalen Klimakonferenzen, speziell des Pariser COP21 Abkommens, gefordert werden
Serum concentrations of levosimendan and its metabolites OR-1855 and OR-1896 in cardiac surgery patients with cardiopulmonary bypass
Background: The inotropic drug levosimendan is often used off-label perioperatively in cardiac surgery patients with cardiopulmonary bypass (CPB). Data regarding serum concentrations of levosimendan and its metabolites within this context is lacking.
Methods: Total serum concentrations (TSC) and unbound fractions (UF) of levosimendan and its metabolites OR-1896 and OR-1855 in cardiac surgery patients with CPB were retrospectively measured using LC-ESI-MS/MS. Simulation of expected levosimendan TSC was performed using Pharkin 4.0. Serum NT-proBNP was assessed with ELISA.
Results: After prolonged levosimendan infusion (1.25â
mg or 2.5â
mg, respectively) after induction of anaesthesia, a median TSC of 1.9â
ng/ml and 10.4â
ng/ml was determined in samples taken directly after surgery (T1). Median TSC of 7.6â
ng/ml and 22.0â
ng/ml, respectively, were simulated at T1. Whereas 1.1â
ng/ml and 1.6â
ng/ml TSC of OR-1896, respectively, was quantified the day after surgery (T2), TSC of the intermediate metabolite OR-1855 was mostly below the lower limit of quantification (LLOQ). The UF was 0.5% and 1.1% for levosimendan and 64.1% and 52.1% for OR-1896, respectively, with over half the samples being below LLOQ. No difference in NT-proBNP concentrations before surgery and T2 was detected.
Discussion: The low TSC, UF and unchanged NT-proBNP levels suggest a need for dose adjustments of levosimendan in this off-label range. In addition, the differences between the measured and estimated concentrations may suggest a possible influence of a CPB on levosimendan serum concentrations. Due to high variation of serum levels between patients, an optimized dosing regimen combined with therapeutic drug monitoring may be advisable
Brane/flux annihilation transitions and nonperturbative moduli stabilization
By extending the calculation of Kahler moduli stabilization to account for an
embiggened antibrane, we reevaluate brane/flux annihilation in a warped throat
with one stabilized Kahler modulus. We find that depending on the relative size
of various fluxes three things can occur: the decay process proceeds
unhindered, the anti-D3-branes are forbidden to decay classically, or the
entire space decompactifies. Additionally, we show that the Kahler modulus
receives a contribution from the collective 3-brane tension. This allows for a
significant change in compactified volume during the transition and possibly
mitigates some fine tuning otherwise required to achieve large volume.Comment: 25 pages, 6 figures, LaTeX. v2: references adde
Bioactive Glass Inhibits Tumor Development from Giant Cell Tumor of Bone-Derived Neoplastic Stromal Cells in a Chicken Chorioallantoic Membrane Assay
Simple Summary
High recurrence rates represent a major problem during the management of giant cell tumors of bone (GCTB). To evaluate the suitability of bioactive glasses (BGs) for the development of new therapeutic strategies, we analyzed the effects of BGs on cell viability and tumor formation. We observed a strong cytotoxic effect of BGs toward primary GCTB cell lines in vitro and a significant reduction of tumor formation and growth using a chicken chorioallantoic membrane (CAM) assay. These data suggest that BGs represent promising candidates for the treatment of GCTBs.
Abstract
Tumor recurrence is a major problem during the treatment of giant cell tumors of bone (GCTB). We recently identified tumor cell-specific cytotoxic effects of bioactive glasses (BGs) toward neoplastic stromal cells derived from GCTB tissue (GCTSCs) in vitro. Since these data indicated a promising role of BGs in the adjuvant treatment of GCTBs, we aimed to investigate the transferability of the in vitro data into the more complex in vivo situation in the current study. We first analyzed the cytotoxicity of three different BGs in vitro by WST-1 assay after co-cultivation with primary GCTSC cell lines. The effects of BGs on tumor engraftment and growth were analyzed by chicken chorioallantoic membrane (CAM) assays and subsequent quantification of tumor take rates and tumor volumes. In vitro, all tested BGs displayed a cytotoxic effect on GCTSCs that was dependent on BG composition, concentration, and particle size. Comparable effects could be observed within the in vivo environment resulting in reduced tumor take rates and tumor volumes in BG-treated samples. These data indicate a possible clinical application of BGs in the context of GCTB therapy, mediating a reduction of recurrence rates with the simultaneous promotion of bone regeneration
The state of the Martian climate
60°N was +2.0°C, relative to the 1981â2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes
Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

The processing and impact of dissolved riverine nitrogen in the Arctic Ocean

The definitive version was published in Estuaries and Coasts 35 (2012): 401-415, doi:10.1007/s12237-011-9417-3.Although the Arctic Ocean is the most riverine-influenced of all of the worldâs oceans, the importance of terrigenous nutrients in this environment is poorly understood. This study couples estimates of circumpolar riverine nutrient fluxes from the PARTNERS (Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments) Project with a regionally configured version of the MIT general circulation model to develop estimates of the distribution and availability of dissolved riverine N in the Arctic Ocean, assess its importance for primary production, and compare these estimates to potential bacterial production fueled by riverine C. Because riverine dissolved organic nitrogen is remineralized slowly, riverine N is available for uptake well into the open ocean. Despite this, we estimate that even when recycling is considered, riverine N may support 0.5â1.5 Tmol C yearâ1 of primary production, a small proportion of total Arctic Ocean photosynthesis. Rapid uptake of dissolved inorganic nitrogen coupled with relatively high rates of dissolved organic nitrogen regeneration in N-limited nearshore regions, however, leads to potential localized rates of riverine-supported photosynthesis that represent a substantial proportion of nearshore production.Funding for this work was provided through NSFOPP-
