Behandlungsstrategien bei Befall mit Echtem und Falschem Mehltau an Arznei- und Gewürzpflanzen im ökologischen Anbau am Beispiel von Blütendrogen, Blattdrogen, Krautdrogen und Körnerdrogen

Laufzeit des BOEL-Projektes (FKZ: 02OE144): Mai 2002 bis Oktober 2003 Ziel des Projektes ist die Einführung praxistauglicher Strategien zur Mehltauregulierung an Arznei- und Gewürzpflanzen im ökologischen Anbau. Die Übertragung von Strategien und Erfahrungen aus anderen Sparten auf die Arznei- und Gewürzpflanzen sollen im Feldversuch geprüft werden, die Schaderreger charakterisiert und in ihrer Biologie beschrieben werden. Ferner wird an der Optimierung der Anbaubedingungen gearbeitet. Geprüft werden Pflanzenschutz- und Pflanzenstärkungsmittel sowie pflanzenbauliche Maßnahmen (Düngung. Bestandesdichte) an vier beispielhaften Kulturen (Anis, Apfelminze, Weidenröschen und Ringelblume)

Behandlungsstrategien bei Befall mit Echtem und Falschem Mehltau an Arznei- und Gewürzpflanzen im ökologischen Anbau am Beispiel von Blütendrogen (Calendula officinalis), Blattdrogen (Mentha rotundifolia), Krautdrogen (Epilobium parviflorum) und Körnerdrogen (Pimpinella anisum)

In dem vorliegenden Projekt wurden Behandlungsstrategien bei Befall mit Echtem und Falschem Mehltau an Arznei- und Gewürzpflanzen beispielhaft an vier Kulturen erarbeitet. Die Regulierung der Schaderreger erfolgte durch den Einsatz von Pflanzenbehandlungsmitteln (Pflanzenschutz- und Pflanzenstärkungsmitteln) sowie deren Kombination mit pflanzenbaulichen Maßnahmen. Zur direkten Schaderregerbekämpfung wurden die Wirkstoffe Lecithin, Kupferoxychlorid und Schwefel geprüft. Zur Stärkung der allgemeinen Pflanzengesundheit wurden einige Pflanzenstärkungsmittel mit unterschiedlichen Wirkmechanismus vorwiegend im Screening getestet (Biplantol, Elot-Vis, FZB 24, Kaliwasserglas, Milsana, Mycosin, Neudo Vital, Oikomb und Steinhauers Mehltauschreck + Telmion). Mit der Variation der Stickstoffversorgung und der Aussaatstärke wurde ferner an einer Optimierung der Anbautechnologie gearbeitet und der Einfluss der gewählten Parameter auf die Gesunderhaltung der Pflanzen geprüft. Die in den zweijährigen Feldversuchsreihen erarbeiteten Ergebnisse erbrachten keine ausreichenden Lösungen der Probleme, sondern konnten nur Tendenzen aufzeigen. Die Versuchsarbeiten wurden durch die klimatischen Bedingungen beider Versuchsjahre (2002, 2003) extrem erschwert. Der Wirkstoff Kupferoxychlorid zeigte beim Einsatz in Körnerdrogen (Pimpinella anisum) befallsmindernde Wirkung. Durch die Pflanzenstärkungsmittel und die geprüften anbautechnischen Maßnahmen ließen sich keine eindeutigen Befallsregulierungen nachweisen. Der Einsatz von Pflanzenstärkungsmitteln zur Sicherstellung höherer Erträge wurde sichtbar. Im Einzelnen zeigten die Versuche zu Blütendrogen (Beispiel Calendula officinalis) keinen Einfluss der Pflanzenbehandlungsmittel und der Variation der Standweite auf den Befall mit Echtem Mehltau. Eine Ertragssteigerung wurde durch die Behandlung mit Milsana erreicht. Die Behandlung mit Milsana zeigte ebenfalls eine ertragsverbessernde Wirkung in den Versuchsanlagen zu Blattdrogen (Beispiel Mentha rotundifolia) und zu Krautdrogen (Beispiel Epilobium parviflorum). Für Apfelminze wurde mit Erysiphe biocellata Ehrenb. erstmals die genaue Art der Echten Mehltau Spezies bestimmt. Das Projekt lieferte wichtige Ansätze zur Regulierung von Mehltaupilzen im ökologischen Arznei- und Gewürzpflanzenanbau und zum Einsatz von Pflanzenstärkungsmitteln bei Sonderkulturen

High Impact Practices (HIPS) Assessment Model: 2015-2016 Pilot Mid-Year Report

A systematic institutional assessment model was developed to investigate the impact of high impact educational practices (HIPs) on undergraduate student success at Virginia Commonwealth University (VCU). The proposed VCU HIPs Assessment Model provides a systematic framework for assessing the impact of high impact educational practices on VCU undergraduates. Recommendations for institutionalizing the VCU HIPs Assessment Model are made

A critical evaluation of the Down syndrome diagnosis for LB1, type specimen of Homo floresiensis

The Liang Bua hominins from Flores, Indonesia, have been the subject of intense scrutiny and debate since their initial description and classification in 2004. These remains have been assigned to a new species, Homo floresiensis, with the partial skeleton LB1 as the type specimen. The Liang Bua hominins are notable for their short stature, small endocranial volume, and many features that appear phylogenetically primitive relative to modern humans, despite their late Pleistocene age. Recently, some workers suggested that the remains represent members of a small-bodied island population of modern Austro-Melanesian humans, with LB1 exhibiting clinical signs of Down syndrome. Many classic Down syndrome signs are soft tissue features that could not be assessed in skeletal remains. Moreover, a definitive diagnosis of Down syndrome can only be made by genetic analysis as the phenotypes associated with Down syndrome are variable. Most features that contribute to the Down syndrome phenotype are not restricted to Down syndrome but are seen in other chromosomal disorders and in the general population. Nevertheless, we re-evaluated the presence of those phenotypic features used to support this classification by comparing LB1 to samples of modern humans diagnosed with Down syndrome and euploid modern humans using comparative morphometric analyses. We present new data regarding neurocranial, brain, and symphyseal shape in Down syndrome, additional estimates of stature for LB1, and analyses of inter- and intralimb proportions. The presence of cranial sinuses is addressed using CT images of LB1. We found minimal congruence between the LB1 phenotype and clinical descriptions of Down syndrome. We present important differences between the phenotypes of LB1 and individuals with Down syndrome, and quantitative data that characterize LB1 as an outlier compared with Down syndrome and non-Down syndrome groups. Homo floresiensis remains a phenotypically unique, valid species with its roots in Plio-Pleistocene Homo taxa

The psychological-type profile of clergywomen in ordained local ministry in the Church of England : pioneers or custodians?

This study employs psychological-type theory to compare the psychological profile of 144 clergywomen serving in ordained local ministry in the Church of England alongside the established profile of 237 professional mobile clergywomen serving in the Church of England published by Francis, Craig, Whinney, Tilley, and Slater. The data found no significant differences between these two groups of clergywomen in terms of orientations (introversion and extraversion) or in terms of the judging process (thinking and feeling). In terms of the perceiving process, there was a significantly higher proportion of sensing types among those serving in ordained local ministry (70% compared with 35%). In terms of the attitudes, there was a significantly higher proportion of judging types among those serving in ordained local ministry (83% compared with 65%). The combined sensing judging (SJ) temperament accounted for 65% of the clergywomen serving in ordained local ministry, compared with 29% of the clergywomen serving in professional mobile ministry in the earlier study. It is argued that the SJ temperament characterises a custodian style of ministry

Real-Gas Effects and Phase Separation in Underexpanded Jets at Engine-Relevant Conditions

A numerical framework implemented in the open-source tool OpenFOAM is presented in this work combining a hybrid, pressure-based solver with a vapor-liquid equilibrium model based on the cubic equation of state. This framework is used in the present work to investigate underexpanded jets at engine-relevant conditions where real-gas effects and mixture induced phase separation are probable to occur. A thorough validation and discussion of the applied vapor-liquid equilibrium model is conducted by means of general thermodynamic relations and measurement data available in the literature. Engine-relevant simulation cases for two different fuels were defined. Analyses of the flow field show that the used fuel has a first order effect on the occurrence of phase separation. In the case of phase separation two different effects could be revealed causing the single-phase instability, namely the strong expansion and the mixing of the fuel with the chamber gas. A comparison of single-phase and two-phase jets disclosed that the phase separation leads to a completely different penetration depth in contrast to single-phase injection and therefore commonly used analytical approaches fail to predict the penetration depth.Comment: Preprint submitted to AIAA Scitech 2018, Kissimmee, Florid

Psychological type and prayer preferences: a study among Anglican clergy in the United Kingdom

This study applies the framework of Jungian psychological type theory to define eight aspects of prayer preference, namely: introverted prayer, extraverted prayer, sensing prayer, intuitive prayer, feeling prayer, thinking prayer, judging prayer, and perceiving prayer. On the basis of data provided by 1,476 newly ordained Anglican clergy from England, Ireland, Scotland, and Wales, eight 7-item scales were developed to access these aspects of prayer preferences. Significant correlations were found between each prayer preference and the relevant aspect of psychological type accessed by the Keirsey Temperament Sorter. These data support the theory that psychological type influences the way in which people pray
