Ausbrüche von Histomonose bei langsamer wachsenden Putenlinien
(2021-09-02)
Histomonosis or Blackhead Disease is a poultry disease caused by infection with the protozoan parasite Histomonas meleagridis. Outbreaks are most frequent in turkey flocks, with often high mortality rates of up to 100%. During a study with three slower growing turkey strains on an organic farm in the years 2015 to 2018, in all three fattening batches outbreaks of histomonosis occured. The disease was diagnosed histologically by PAS-staining, in some cases PCR detection was performed. Heterakis gallinarum could not ...

Feed digestibility, digesta passage and faecal microbial biomass in desert-adapted goats exposed to mild water restriction
(2021-07-18)
In arid and semi-arid environments, extensively managed ruminants regularly experience drinking water shortage, especially in the dry season. The present study therefore investigated the effects of mild drinking water restriction on feed intake, feed digestibility, solid digesta passage and composition of faeces including faecal microbial biomass. A feeding trial was conducted in Oman, during the dry summer months.
Nine adult male Batinah goats were subjected to three watering regimes in a 3 × 3 Latin Square design. ...

Multiscale modeling of ferroelectrics with stochastic grain size distribution
(2021-12-20)
Macroscopic properties of ferroelectrics are controlled by processes on the microscale, in particular the switching of crystal unit cells and the movement of domain walls, respectively. Besides these microscopic levels, the grains of a polycrystalline material constitute the mesoscopic scale. Interactions of grains with statistically distributed orientations, as a consequence of mechanical and electrostatic mismatch, give rise to for example, residual stress which in turn affects domain switching. A multiscale modeling ...

Phenomena-centered Text Analysis (PTA): a new approach to foster the qualitative paradigm in text analysis
(2021-12-06)
Content or text analysis is one of the most common evaluation methods employed in qualitative research. Despite its wide application, however, a clear structure of how such evaluation should be conducted is often lacking due to the complexity of qualitative data. As a consequence, highly differentiated category systems with small-step subdivisions of categories and sub-categories are often used, leading to a loss of context both among categories and for the content as a whole.
The aim of this paper is to describe ...

Taking stock of the field of populism research: Are ideational approaches ‘moralistic’ and postfoundational discursive approaches ‘normative’?
(2021-04-23)
This article sets out to examine two claims that have increasingly come to define the dividing lines between the ideational and the post-foundational discursive approaches to populism: namely, that the former is moralistic and the latter is normative in orientation. The article considers the conceptual merits of both critiques while using them to further examine some of the implicit assumptions and pitfalls within Cas Mudde’s and Ernesto Laclau’s paradigmatic conceptualizations of populism. It is argued that ideational ...

Land cover transitions and effects of transhumance on available forage biomass of rangelands in Benin
(2021-11-30)
This study examined the effects of transhumance pressure on total abavoe-ground biomass and forage availability on rangelands in Benin. We also investigated the implications of land cover transitions on rangelands over a 31-year period. Our work was carried out in three regions of Benin representing distinct phytogeographic regimes: Ketou, Tchaourou, and Sinende. Ground-truthing and biomass sampling of the herbaceous and phanaerophyte strata were carried out between the 2016 peak vegetation period and the onset of ...

Von Lefort zu Mouffe. Populismus als Moment und Grenze radikaler Demokratie
(2021-06-10)
In diesem Beitrag werden Chantal Mouffes jüngste Interventionen für den Linkspopulismus zum Anlass für eine theoretische Reflexion über das Spannungsverhältnis zwischen Populismus und radikaler Demokratie genommen. Im Lichte der radikalen Demokratietheorien Claude Leforts, Jacques Rancières, Ernesto Laclaus und Chantal Mouffes, der Populismustheorie Laclaus sowie der einschlägigen Rezeption wird argumentiert, dass der Populismus sowohl konstitutives Moment als auch Grenze eines radikalen Demokratieverständnisses ...

Investigating the Effect of Different Drying Strategies on the Quality Parameters of Daucus carota L. Using Dynamic Process Control and Measurement Techniques
(2021-03-21)
The present work aims to improve the understanding of the effect of different drying strategies at varying temperatures on the dynamic drying behaviour and quality of organic products such as carrots using non-invasive measurement techniques. For this purpose, carrot slices of 3 mm thickness were dried under three different strategies namely air temperature controlled (A), product temperature controlled (P) and stepwise temperature controlled (S) at different temperatures (50 °C, 60 °C and 70 °C) to measure and analyse ...

The Whole and the Parts—A New Perspective on Production Diseases and Economic Sustainability in Dairy Farming
(2021-08-12)
The levels of production diseases (PD) and the cow replacement rate are high in dairy farming. They indicate excessive production demands on the cow and a poor state of animal welfare. This is the subject of increasing public debate. The purpose of this study was to assess the effect of production diseases on the economic sustainability of dairy farms. The contributions of individual culled cows to the farm’s economic performance were calculated, based on milk recording and accounting data from 32 farms in Germany. ...

How political philosophies can help to discuss and differentiate theories in community ecology
(2021-04-09)
This paper uses structural analogies to competing political philosophies of human society as a heuristic tool to differentiate between ecological theories and to bring out new aspects of apparently well-known classics of ecological scholarship. These two different areas of knowledge have in common that their objects are ‘societies’, i.e. units composed of individuals, and that contradictory and competing theories about these supra-individual units exist. The benefit of discussing ecological theories in terms of their ...
