Assessing spatial variability of barley whole crop biomass yield and leaf area index in silvoarable agroforestry systems using UAV-borne remote sensing
(2021-07-13)
Agroforestry systems (AFS) can provide positive ecosystem services while at the same time stabilizing yields under increasingly common drought conditions. The effect of distance to trees in alley cropping AFS on yield-related crop parameters has predominantly been studied using point data from transects. Unmanned aerial vehicles (UAVs) offer a novel possibility to map plant traits with high spatial resolution and coverage. In the present study, UAV-borne red, green, blue (RGB) and multispectral imagery was utilized ...

Sustainability Transitions in University Food Service—A Living Lab Approach of Locavore Meal Planning and Procurement
(2021-06-29)
Due to its purchasing power, the public food service sector is viewed as a potential transformative driver towards sustainable food systems. Organic meal planning and regional procurement may be a vital implementation strategy towards Planetary Health Diets in the communal catering arena. Capable of unleashing desirable synergies within local foodsheds, this transition pathway can potentially benefit all stages of the value chain, while also positively influencing consumer dietary behavior. Transformation, however, ...

Cyclic nucleotide-dependent ionic currents in olfactory receptor neurons of the hawkmoth Manduca sexta suggest pull–push sensitivity modulation
(2021-06-14)
Olfactory receptor neurons (ORNs) of the hawkmoth Manduca sexta sensitize via cAMP- and adapt via cGMP-dependent mechanisms. Perforated patch clamp recordings distinguished 11 currents in these ORNs. Derivatives of cAMP and/or cGMP antagonistically affected three of five K+ currents and two non-specific cation currents. The Ca2+-dependent K+ current IK(Ca2+) and the sensitive pheromone-dependent K+ current IK(cGMP−), which both express fast kinetics, were inhibited by 8bcGMP, while a slow K+ current, IK(cGMP+), was ...

Recent Progress in Synthesis and Application of Nanosized and Hierarchical Mordenite—A Short Review
(2021-02-26)
Zeolites with their unique properties find applications in various fields, including medicine, agronomy, ecology, production of detergents and drying agents, and in a number of industrial processes. Among zeolites, mordenite is particularly widespread because of its high silica/alumina ratio, which allows it to resist exposure to high temperatures and to acidic gases and liquids. Mordenite is commercially available as a natural mineral and as a synthesized material. This zeolite is mostly used in its synthetic form ...

Investment Decisions with Endogeneity: A Dirichlet Tree Analysis
(2021-07-01)
Ignoring endogeneity when assessing investors’ decisions carries the risk of biased estimates for the influence of exogeneous marketing variables. This study shows how to overcome this challenge by using Pólya trees in the quantification of impacts on investors’ decisions. A total of 2255 investors recruited for this study received and opened a digital marketing newsletter about investing daily. Given the nature of investors’ decisions characterized by heterogeneity and endogeneity, the response model is assessed ...

Comparison of Spaceborne and UAV-Borne Remote Sensing Spectral Data for Estimating Monsoon Crop Vegetation Parameters
(2021-04-20)
Various remote sensing data have been successfully applied to monitor crop vegetation parameters for different crop types. Those successful applications mostly focused on one sensor system or a single crop type. This study compares how two different sensor data (spaceborne multispectral vs unmanned aerial vehicle borne hyperspectral) can estimate crop vegetation parameters from three monsoon crops in tropical regions: finger millet, maize, and lablab. The study was conducted in two experimental field layouts (irrigated ...

Coaching zum Spannungsfeld von Dominanz und Unterordnung – Perspektiven für eine situationsadäquate Selbstregulation
(2021-10-27)
Die Forschung widmete sich der Frage, wie Einzelcoaching dazu beiträgt, dass Coachees eine situationsadäquate Selbstregulation von Dominanz und Unterordnung gelingt. Zunächst wird die Relevanz des Themas für die Coachingpraxis und das Spannungsfeld von Dominanz und Unterordnung erörtert. Das Instrument der operationalisierten psychodynamischen Diagnostik diente als Grundlage für das Forschungsdesign. Anschließend wird die verwendete Methode beschrieben, und die Ergebnisse der Forschung werden komprimiert dargelegt. ...

Influence of hot deformation on the precipitation hardening of high-strength aluminum AA7075 during thermo-mechanical processing
(2021-04-21)
The aim of this work was to investigate the effect of hot deformation on the aging behavior of precipitation-hardenable aluminum alloy AA7075 within a novel thermo-mechanical forming process, in order to gain insight into its precipitation kinetics. For this purpose, the material was formed at 420 °C after undergoing solution treatment to different strain levels ranging from 2% to 10% to obtain different dislocation densities. After undergoing hot deformation, aging at 120 °C with different parameters was carried out ...

Der innerpsychische Konflikt Individuation vs. Abhängigkeit im Coaching: Zentrale Ergebnisse einer qualitativen Studie zur Praxis erfahrener Coaches
(2021-11-09)
Die unbewusste Dynamik von innerpsychischen Konflikten ist ein wichtiger Inhalt des Erlebens und Verhaltens von Menschen und hat vermutlich einen Einfluss in Coachingprozessen. Diese Studie fokussiert den Grundkonflikt „Individuation vs. Abhängigkeit“ in Einzelcoachings. In einer kleinen qualitativen Feldstudie (n = 13) wurden erfahrene Coaching-Expert/innen zu subjektiven Theorien und präferierten Arbeitskonzepten im Handling dieses Konflikts im Einzelcoaching befragt. Die Inhaltsanalyse zeigt Strategien zum Handling ...

Liquid Silicone Rubber Foams Made with Water as Blowing Agent
(2021-08-18)
Liquid silicone rubber (LSR) is primarily used in injection molding. Foamed molded parts made of LSR are almost nonexistent because the process reliability of LSR foam injection molding is currently not given. It makes sense to have suitable foaming processes for this material as well, because the density of this elastomer is about 1.15 g cm−3. With the injection molding process presented herein for foaming LSR, density reductions of up to 40% can be achieved. In this process, up to 3% by weight of water is added to ...
