51. Narrow-band transmission spectroscopy from high dispersion spectra

Author

Seidel, Julia

Abstract

In this review talk, I will walk through the most common complications when building a transmission spectrum (as a reminder from the hands-on workshop earlier in the week). I will then highlight the most important results of recent years in the realm of narrow-band transmission spectroscopy using high dispersion spectra with a focus on the different spectrographs currently capable of these works. I will then move on to provide an outlook into which instruments will or might be used in the near future to perform transmission spectroscopy. Lastly, the different uses of resolved spectral lines in studying exoplanet atmospheres are explored in an outlook.

Abstract

This thesis benchmarked a new probe of atmospheric dynamics in exoplanet atmospheres by resolving the spectral lines stemming from these far atmospheres and then modelling their line shape taking into account the broadening from atmospheric winds. This gives us a window into atmospheric winds for these far away worlds only limited by the depths of the resolved lines. I resolved the sodium doublet for a wide array of exoplanets and applied the novel modelling technique to the hot Jupiter HD189733b and the ultra hot Jupiter WASP-76b. I found that both are dominated by zonal winds in the lower, and vertical winds in the intermediate atmosphere, a first to date. This novel approach pushes the limits of high-resolution transit spectroscopy, which is evolving from an element detection technique to a more holistic atmospheric characterisation technique.

Abstract

The objectives of this paper were (i) to perform a systematic review of the literature over the last 21 yr and (ii) to evaluate the efficacy of selective dry cow treatment (SDCT) vs. blanket dry cow treatment (BDCT) in dairy cows regarding the risk of intramammary infection (IMI) after calving, new IMI risk after calving, cure risk during the dry period, and a reduction in antibiotic use at drying-off by meta-analysis. The final number of included studies was n = 3 for IMI risk after calving and n = 5 for new IMI risk after calving, cure risk during the dry period, and antibiotic use. The relative risk (RR) levels for IMI, new IMI, and cure did not differ significantly between SDCT and BDCT. This meta-analysis provides evidence that SDCT seems to be an adequate alternative to BDCT regarding udder health with a simultaneous reduction in antibiotic use. Limitations might arise because of the small number of studies included.:1. Introduction 2.

Die finale Anzahl eingeschlossener Studien war n = 3 für das IMI-Risiko pp sowie n = 5 für Neuinfektionenrisiko pp, Heilungsrisiko während dem Trockenstehen und Antibiotikaeinsatz zum Trockenstellen. Die relativen Risiken für IMI pp, Neuinfektionen pp und Heilung während der Trockenstehperiode unterschieden sich dabei nicht signifikant zwischen SDCT und BDCT. Diese Meta-Analyse erbringt Evidenz, dass SDCT eine adäquate Alternative zu BDCT im Hinblick auf Eutergesundheit und Antibiotikareduktion ist.

Abstract

Today, the grid frequency is predominantly controlled by conventional power plants. However, the increasing installed power of distributed energy resources and the declining amount of synchronous generators make it essential that wind farms as well as photovoltaic systems take over tasks of frequency control. Although photovoltaic systems are able to provide control reserve from a technical point of view, market and regulatory conditions are not designed for them to participate. Due to power electronics photovoltaic inverters are able to react even faster to frequency deviations than conventional power plants do. Using this characteristic, the contribution of photovoltaic systems to stabilizing the grid frequency is analyzed. Therefore, a new control reserve product, called fast Frequency Containment Reserves is developed. [ABSTRACT FROM AUTHOR]

Abstract

Background: China is the country with the worldwide hugest hydropower reserves. Interms of meeting its electricity demand, further development of its reserves is necessary.European companies are leading on the hydropower market and strive for projects inChina, resulting in challenges and opportunities while facing emerging market features.Aim: This study presents an analysis of the Chinese electricity market with the aim toidentify challenges and opportunities European hydropower companies face whenoperating or entering this market. The analysis uses Blue Ocean as strategic tool to finda new perspective of examining the market situation and potential.Definition: The OECD (2007) defined hydropower as “electricity generation using thepower of falling water”.Method: This study is based on qualitative research. It constitutes five expertinterviews with company employees as Voith and a professor for fluid mechanics andhydraulic machinery at Stuttgart University.Results: The analysis resulted in 12 challenges and opportunities for Europeanhydropower companies. The challenges arise mainly from political influence on theChinese market. Opportunities, on the other hand, have strategic implications on alltime horizons but focus on different technologies and directions. The long term strategicopportunity was identifies by applying the Blue Ocean strategy. Further this proves theex ante applicability of the Blue Ocean strategy.

Abstract

Hintergrund und Ziele Erwachsene, die von einer intrauterinen Wachstumsrestriktion (IUGR) betroffen waren, weisen ein erhöhtes kardiovaskuläres Mortalitätsrisiko auf. Barker formulierte bereits 1992 einen hypothetischen Zusammenhang zwischen niedrigem Geburtsgewicht und dem erhöhtem Risiko, im späteren Leben an dem metabolischen Syndrom zu erkranken, welches Adipositas, arterielle Hypertonie, koronare Herzkrankheit sowie Diabetes mellitus Typ II subsumiert. Er postulierte eine Ätiologie dieser Morbiditäten bereits in der intrauterinen Phase und machte dafür ein gestörtes endokrines Milieu verantwortlich. Für den Prozess, welcher beim Feten eine endokrine Dysregulation mit postpartalen Langzeitfolgen induziert, wurde der Begriff „fetale Programmierung“ eingeführt. In den letzten Jahren ist dabei der plazentare Glukokortikoidstoffwechsel vermehrt in den Fokus des wissenschaftlichen Interesses getreten. Es konnte gezeigt werden, dass Glukokortikoide fetale Programmierungsvorgänge auslösen, die denen der IUGR ähneln. Eine vermittelnde Rolle könnten hierbei Leptin, 11-HSD2 und IGFBP1 spielen. Der Schwerpunkt der vorliegenden Arbeit war es, veränderte Genexpressionen der drei Proteine in vitro an isolierten villösen Trophoblasten einer gesunden Plazenta nach Glukokortikoidexposition zu untersuchen. Es galt weiterhin zu prüfen, ob sich durch Dexamethason bedingte Veränderungen der Leptin-mRNA-Expression auch auf Proteinebene nachweisen lassen. Methoden Zur Gewinnung des Zellmaterials wurden aus Plazenten gesunder Schwangerschaften primäre villöse Trophoblasten mittels Percoll-Methode isoliert. Anschließend wurden Monolayer-Zellkulturen in dreifachen Ansätzen mit 10µM Dexamethason für die Zeiträume 6h, 12h, 24h, 48h und 72h inkubiert. Nach RNA-Extraktion und Reverser Transkription wurde die Genexpression mittels TaqMan-Real-Time-PCR ermittelt. Zusätzlich wurde durch einen ELISA die Proteinkonzentration von Leptin in den Zellkulturüberständen bestimmt, sowie der trophoblastäre Reifemarker -hCG gemessen. Ergebnisse und Beobachtungen Eine Dexamethason-Behandlung (10µM) induzierte die Leptinexpression in trophoblastären Zellen sowohl auf RNA-, als auch auf Protein-Ebene signifikant. Die 11-HSD2-mRNA-Expression ließ sich ebenfalls signifikant durch Dexamethason stimulieren. Die Expressionsrate von IGFBP1-mRNA sprach hingegen nicht signifikant auf eine Stimulation mit Dexamethason an. Dexamethason induzierte in primären villösen Trophoblasten außerdem die -hCG-Produktion als Surrogat für eine Reifung. Die Laktatdehydrogenase (LDH)-Konzentrationen in den Überständen der Zellkultur unterlagen während der gesamten Inkubation keiner signifikanten Steigerung, was einen erhöhten apoptotischen Zellverlust unwahrscheinlich machte. Schlussfolgerung Am in vitro Modell des primären villösen Trophoblasten ließ sich der regulative Einfluss von Glukokortikoiden auf mögliche Regulationsfaktoren der fetalen Programmierung zeigen. Diesen Glukokortikoid-Effektorproteinen sollte daher in Folgeversuchen in vivo besondere Aufmerksamkeit gewidmet werden. Background and purpose Adults who were affected by intrauterine growth restriction (IUGR) bear a higher risk of cardiovascular mortality. Already in 1992 Barker phrased a hypothetical correlation between low birth weight and an increased risk of suffering from the metabolic syndrome in later life. This syndrome contains adiposity, hypertension, coronary heart disease and diabetes mellitus type 2. He postulated that the etiologies of these morbidities are already founded intrauterine and he considered a disordered endocrine setting responsible. For the process of inducing a fetal endocrine dysregulation with long-term consequences, the term „fetal programming“ was established. In the last few years placental glucocorticoid metabolism has been a matter of particular scientific interest. It could be shown that glucocorticoids initiate fetal programming procedures, which are similar to the process found in IUGR development. A meditative role at this could take Leptin, 11-HSD2 and IGFBP1. The purpose of the present study was to examine altering gene expressions of these three proteins in vitro in isolated villous trophoblastic cells of a healthy placenta after exposition to glucocorticoids. Furthermore it was to prove, if the alterations caused by dexamethasone can also be verified in protein levels. Methods From placentas of healthy pregnancies primary villous trophoblastic cells were isolated by the Percoll-method. Afterwards monolayer cell cultures were incubated with 10µM dexamethasone for 6h, 12h, 24h, 48h and 72h in triplets. After extracting the RNA and performing reverse transcription the gene expression was detected by TaqMan-Real-Time-PCR. In addition the concentration of leptin and the trophoblast maturity marker -hCG were determined in medium of incubated cells. Results The treatment with dexamethasone (10µM) significantly induced the expression of leptin in trophoblastic cells on both RNA and protein levels. Expression of 11-HSD2 mRNA could also be significantly stimulated by dexamethasone. The expression rate of IGFBP1 mRNA however did not respond significantly to the treatment with dexamethasone. Dexamethasone furthermore induces the production of -hCG in primary villous trophoblastic cells and therefore their maturation. The concentration of lactat dehydrogenase (LDH), detected in the medium of the cell culture, show no significant increase during the complete incubation period. This reduces the possibility of increased apoptotic cell damage. Conclusion In the in vitro model of the primary villous trophoblast cell the regulative influence of glucocorticoids on fetal programming-associated target genes could be demonstrated. In follow-up trials further focus should be put on these effector proteins, especially in vivo.

Abstract

In this paper an overview of the future role of inverters regarding frequency control in an interconnected system is given. The grid frequency of today's electrical power system is mainly stabilized by synchronous generators, especially concerning inertia and primary control reserve. As the power system characterized by large, conventional power plants has been changing towards an inverter-dominated one, these systems have to take over responsibility for grid stability and frequency control as well. Two types of inverters are presented in this paper: voltage control mode inverters and current control mode inverters. Both types are presented with their similarities and differences in functionality. Voltage control mode inverters are qualified for instantaneous reactions on frequency deviations, comparable to inertia from synchronous generators, whereas current control mode inverters are suited for delivering (fast) primary control reserve. Multiple laboratory measurements illustrate these different fields of application and validate the qualification of inverters for frequency control. [ABSTRACT FROM AUTHOR]

Der Einsatz der Fachcommunity war immens – und hat die Disziplin allem Anschein nach dauerhaft verändert. Die Publikation untersucht fachspezifische Erfahrungen aus der Pandemiezeit, kontextualisiert sie und entwickelt daraus Perspektiven. Dabei geht es nicht nur um den Gegensatz zwischen Präsenz- und Distanzformaten, sondern auch um grundsätzlichere Herausforderungen an das Fach. Die 28 Autor:innen u. a. aus den Bereichen Schule, Hochschule und Museum argumentieren und spekulieren in unterschiedlicher Weise, bisweilen auch zueinander im Widerspruch. Insgesamt ergibt sich so ein erstes Bild davon, was eine Kunstpädagogik nach der Pandemie ausmachen könnte.

Abstract

Abstract: Peroxiredoxin 6 (Prx 6) is a bifunctional enzyme with both glutathione peroxidase and acidic Ca2+-independent phospholipase A2 activities. We have recently shown that exposure of murine bone marrow-derived macrophages to LPS and IFN-γ leads to induction of COX-2 expression and secretion of PGE2, up-regulating Prx 6 mRNA levels. This study was designed to investigate various prostaglandins (PGs) for their ability to induce gene expression of Prxs, in particular Prx 6, and to determine the underlying regulatory mechanisms. We provide evidence that both conventional and cyclopentenone PGs enhance Prx 6 mRNA expression. Treatment with either activators or inhibitors of adenylate cyclase as well as cAMP analogs indicated that Prx 6 gene expression is regulated by adenylate cyclase in response to PGD2 or PGE2. Furthermore, our study revealed that JAK2, PI3K, PKC, and p38 MAPK contribute to the PGD2- or PGE2-dependent Prx 6 induction. Using stimulated macrophages from Nrf2-deficient mice or activators of Nrf2 and PPARγ, we found that Nrf2, but not PPARγ, is involved in the PG-dependent increase in Prx 6 mRNA expression. In summary, our data suggest multiple signaling pathways of Prx 6 regulation by PGs and identified Nrf2 as a critical player mediating transcriptional induction. [Copyright &y& Elsevier]
