Möglichkeiten und Grenzen der Nutzung von Temperatursummen für die Terminierung von Aussaat und Umbruch einer Winterzwischenfrucht zur Kontrolle von Meliodogyne hapla im Ökologischen Landbau

Pflanzenparasitäre Nematoden verursachen bedeutende wirtschaftliche Schäden im ökologischen Landbau (Paffrath et al. 2005). Vorwiegend betroffen sind Betriebe mit einem hohen Anteil an Feldgemüse in der Fruchtfolge. Für Nematoden mit einem breiten Wirtspflanzenspektrum wie Meloidogyne hapla bieten sich über die Fruchtfolge, Unkrautbesatz und kurze Brachezeiten kontinuierlich Wirtspflanzen im Bestand. Insbesondere Leguminosen, eine entscheidende Stickstoffquelle im ökologischen Landbau, sind hervorragende Wirtspflanzen für M. hapla und andere pflanzenparasitäre Nematodenarten. Derzeit sind kaum praxisrelevante Maßnahmen zur Reduzierung pflanzenparasitärer Nematoden verfügbar oder aber, wie im Falle der Schwarzbrache, wenig ökologisch. Ziel des Projektes war es, den Anbau von Leguminosen als Winterzwischenfrucht in einen Zeitraum zu verlegen, in denen die Nematoden nur eingeschränkt aktiv sind. Unter der Annahme, dass M. hapla bei Bodentemperaturen unter 8°C nicht aktiv ist (Vrain et al. 1978), sollte es bei entsprechend später Aussaat im Herbst und entsprechend zeitigem Umbruch im Frühjahr nicht zu einer Vermehrung der Nematoden kommen. Die Zeit für den Abschluss einer Nematodengeneration wurde mithilfe der Temperatursumme über 8°C ermittelt. Grundlage hierfür bildeten Feldversuche mit Salat (Heinicke et al. 2002, 2003, 2004) sowie Literaturrecherchen (Lahtinen et al. 1988, Mercer 1990), nach denen für den Abschluss einer Generation von M. hapla eine Temperatursumme von 450°C erforderlich ist. Die Untersuchungen zeigen, dass mit einer überwinternden Winterzwischenfrucht einerseits Stickstoff fixiert, andererseits auch der Wurzelgallennematode M. hapla erfolgreich reduziert werden kann, vorausgesetzt, der Umbruch im Frühjahr erfolgt rechtzeitig. Zur Ermittlung des rechtzeitigen Umbruchtermines kann grundsätzlich die Temperatursumme herangezogen werden, wenn sie entsprechend angepasst wird. Voraussetzung hierfür ist ein besseres Verständnis kühler Temperaturen auf die Entwicklung von M. hapla

Structural Reliability of AlGaN/GaN High Electron Mobility Transistors

The GaN devices have significant advantages in terms of power density, characteristics and voltage range based on conventional compound semiconductors or Silicon. The aim of this work is to observe and analyze the results of 3D Structural Reliability of AlGaN/GaN HEMT structure. The work is mostly focused on the coupled behavior of Aluminum Gallium-nitride (AlGaN)/ Gallium-nitride (GaN) high-electron- mobility transistors (HEMTs). The modeling have to be performed considering to the various coupled properties like piezo- electric effect, inverse piezoelectric effect, mechanical stress, Joule heating effect etc. The Structural Reliability with modeling of AlGaN/GaN HEMTs is performed using ANSYS and MATLAB simulation software

Brainstages THE ROLES OF BRAIN IN HUMAN COGNITIVE DEVELOPMENT

ABSTRACT Brain development in humans occurs stagewise in correlation with the onsets of the main Piagetian stages of reasoning development. This allows a description of cognitive development as resulting partially from and dependent upon biological events occurring in the brain. Evidence shows that some eventual brain structures depend on a combination of biological events and instructional or experiential inputs. Such a description thereby permits some novel working hypotheses about normal cognitive development and how to foster it, as well as suggesting alternative ways of creating intervention programs for children from deprived environments. Piagetian and Neo-Piagetian theories of human cognitive abilities attempt to describe what happens developmentally leading up to the mature state. They describe this almost entirely in terms of the psycho-social factors involved. But, cognitive functions and changes are more readily and more accurately understood and described if attention is also, if not first, paid to the facts of brain growth. That understanding also permits parents and teachers to see ways to enhance children's cognitive development

An examination of chemistry and transport processes in the tropical lower stratosphere using observations of long-lived and short-lived compounds obtained during STRAT and POLARIS

A suite of compounds with a wide range of photochemical lifetimes (3 months to several decades) was measured in the tropical and midlatitude upper troposphere and lower stratosphere during the Stratospheric Tracers of Atmospheric Transport (STRAT) experiment (fall 1995 and winter, summer, and fall 1996) and the Photochemistry of Ozone Loss in the Arctic Region in Summer (POLARIS) deployment in late summer 1997. These species include various chlorofluorocarbons, hydrocarbons, halocarbons, and halons measured in whole air samples and CO measured in situ by tunable diode laser spectroscopy. Mixing ratio profiles of long-lived species in the tropical lower stratosphere are examined using a one-dimensional (1-D) photochemical model that includes entrainment from the extratropical stratosphere and is constrained by measured concentrations of OH. Profiles of tracers found using the 1-D model agree well with all the observed tropical profiles for an entrainment time scale of 8.5-4+6 months, independent of altitude between potential temperatures of 370 and 500 K. The tropical profile of CO is used to show that the annually averaged ascent rate profile, on the basis of a set of radiative heating calculations, is accurate to approximately ±44%, a smaller uncertainty than found by considering the uncertainties in the radiative model and its inputs. Tropical profiles of ethane and C2Cl4 reveal that the concentration of Cl is higher than expected on the basis of photochemical model simulations using standard gas phase kinetics and established relationships between total inorganic chlorine and CFC-11. Our observations suggest that short-lived organic chlorinated compounds and HCl carried across the tropical tropopause may provide an important source of inorganic chlorine to the tropical lower stratosphere that has been largely unappreciated in previous studies. The entrainment timescale found here is considerably less than the value found by a similar study that focused on observations obtained in the lower stratosphere during 1994. Several possible explanations for this difference are discussed. Copyright 1999 by the American Geophysical Union

The South African Stress and Health (SASH) study: 12- month and lifetime prevalence of common mental disorders

Background. The South African Stress and Health (SASH) study is the first large-scale population-based study of common mental disorders in the country. This paper provides data on the 12-month and lifetime prevalence of these conditions.Methods. Data from a nationally representative sample of 4 351 adults were analysed. Mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). An extensive survey questionnaire detailed contextual and socio-demographic factors, onset and course of mental disorders, and risk factors. Simple weighted cross-tabulation methods were used to estimate prevalence, and logistic regression analysis was used to study correlates of 12-monthand lifetime prevalence.Results. The lifetime prevalence for any disorder was 30.3%, and the most prevalent 12-month and lifetime disorders were the anxiety disorders. The Western Cape had the highest 12-month and lifetime prevalence rates, and the lowest rates were in the Northern Cape.Conclusions. The SASH study shows relatively high 12-monthand lifetime prevalence rates. These findings have significant implications for planning mental health services

Impact of common mental disorders during childhood and adolescence on secondary school completion

There are few data from South Africa and other low- and middle-income countries on how mental disorders in childhood and adolescence may influence different aspects of socio-economic position, including educational attainment. We examined the association between early-onset disorders and subsequent educational achievement in a nationallyrepresentative sample of 4 351 South African adults. After adjusting for participant demographic characteristics and traumatic life events, post-traumatic stress disorder, major depressive disorder and substance-related disorders were each associated with increased odds of failing to complete secondary education (odds ratios and 95% confidenceintervals 2.3, 1.0 - 5.1; 1.7, 1.2 - 2.5, and 1.7, 1.2 - 2.5, respectively). These data point to the role that early-life mental disorders may play in educational achievement and subsequent socio-economic position over the life course
