Automatic Assessment of Keel Bone Damage in Laying Hens at the Slaughter Line
Simple Summary Keel bone damage (KBD) is very prevalent in commercial laying hen flocks with a wide range of affected hens/flock. It can cause pain, and affected hens have been found to be less mobile. The assessment of this animal welfare indicator provides important feedback for the farmer about flock health and consequently on the need for interventions. However, the assessment of keel bone damage is time-consuming, and prior training is needed in order to gain reliable results. Optical detection methods can be ...
Differenzierung und Professionalisierung der personenbezogenen Beratungsformate
Die Diskussion über den Stand der Professionalisierung und sowie über den Professionsanspruch personenbezogener Prozessberatung begleitet die fachliche Entwicklung der Beratung von ihren Anfängen an. Dabei hat sich diese Beratungsform inzwischen so erfolgreich etabliert, dass auch klassische Unternehmensberatungsfirmen, die ihre Dienstleistung vormals ausschließlich auf der Basis betriebswirtschaftlicher und juristischer Expertise anboten und großen Wert auf Distanz zu psychologisch orientierten Ansätzen legten, ...
Measurement and analysis of residual stresses and warpage in fiber reinforced plastic and hybrid components
Glass/carbon fiber reinforced plastic (GFRP/CFRP) and hybrid components have attracted increasing attention in lightweight applications. However, residual stresses induced in the manufacturing process of these components can result in warpage and, eventually, negatively affect the mechanical performance of the composite structures. In the present work, GFRP, CFRP, GFRP/steel and CFRP/steel hybrid components were manufactured through the prepreg-press-technology always employing the same process parameters. The residual ...
Does social exclusion improve detection of real and fake smiles? A replication study
Research on social exclusion suggests an increased attention of excluded persons to subtle social cues. In one study (N = 32), published in Psychological Science,Bernstein et al. (2008) provided evidence for this idea by showing that participants in the social exclusion condition were better in correctly categorizing a target person’s smile as real or fake. Although highly cited, this finding has never been directly replicated. The present study aimed to fill that gap. 201 participants (79.1% female) were randomly ...
A Study of Extensions of Classical Summation Theorems for the Series 3F2 and 4F3 with Applications
Very recently, Masjed-Jamei & Koepf [Some summation theorems for generalized hypergeometric functions, Axioms, 2018, 7, 38, 10.3390/axioms 7020038] established some summation theorems for the generalized hypergeometric functions. The aim of this paper is to establish extensions of some of their summation theorems in the most general form. As an application, several Eulerian-type and Laplace-type integrals have also been given. Results earlier obtained by Jun et al. and Koepf et al. follow special cases of our main findings.
The organic mindset: insights from a mixed methods grounded theory (MM-GT) study into organic food systems
A broad understanding of food systems includes a complex web of activities, outcomes and drivers, encompassing not only the food and agriculture sectors, but also the social norms and cultures in which those activities are embedded. The organic food and farming movement has lately been portrayed as a food system of its own right, since it contains all necessary sub-systems, consisting of food environments, distribution networks, processing, as well as production and supply, all of which are bounded by an organic ...
Recent Progress in Synthesis and Application of Nanosized and Hierarchical Mordenite—A Short Review
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 ...
Prediction of biomass and N fixation of legume-grass mixtures using sensor fusion
European farmers and especially organic farmers rely on legume–grass mixtures in their crop rotation as an organic nitrogen (N) source, as legumes can fix atmospheric N, which is the most important element for plant growth. Furthermore, legume–grass serves as valuable fodder for livestock and biogas plants. Therefore, information about aboveground biomass and N fixation (NFix) is crucial for efficient farm management decisions on the field level. Remote sensing, as a non-destructive and fast technique, provides ...
Laser welding of grey cast iron with spheroidal graphite-influence of process parameters on crack formationand hardness
In the investigation at hand, sheets of ferritic and pearlitic grey cast iron with spheroidalgraphite are welded using a fiber-laser. The influence of varying laser power and welding speed onthe macroscopic characteristics of the weld seam and crack formation are analyzed and discussed.Substantial crack formation with crack densities of up to2.93 cm−1are found. Furthermore, hardnessmeasurements are conducted to evaluate the formation of brittle phases within the weld metaland heat-affected zone. Peak hardness values ...
How and why does the attitude-behavior gap differ between product categories of sustainable food? Analysis of organic food purchases based on household panel data
Organic agriculture promotes the transformation toward sustainability because of positive effects for the environment. The organic label on food products enables consumers to make more sustainable purchasing decisions. Although the global market for organic food has grown rapidly in recent years, only a part of the organic product range benefits from this positive trend. To develop the organic market further, it is important to understand the food-related values and attitudes that drive the purchase of organic food. ...
