Evidence for cell turnover as the mechanism responsible for the transport of embryos towards the vagina in viviparous onychophorans (velvet worms)
(2019-06-07)
Background
Onychophorans, commonly known as velvet worms, display a remarkable diversity of reproductive strategies including oviparity, and placentotrophic, lecithotrophic, matrotrophic or combined lecithotrophic/matrotrophic viviparity. In the placentotrophic species, the embryos of consecutive developmental stages are attached to the uterus via a placental stalk, suggesting they might be transported passively towards the vagina due to proximal growth and distal degeneration of tissue. However, this assumption has ...

Influence of blend proportion and baking conditions on the quality attributes of wheat, orange‑fleshed sweet potato and pumpkin composite flour dough and bread: optimization of processing factors
(2023-02-16)
Orange-fleshed sweet potato (OFSP) and pumpkin fruit are underutilized crops with great potential for the production of high-quality bread with health-enhancing properties. However, the incorporation of nonconventional flour in bread formula may influence the dough and bread quality properties. This study investigated the effect of partial substitution of wheat flour with OFSP (10–50%) and pumpkin flour (10–40%), baking temperature (150–200 °C) and baking time (15–25 min) on the quality properties of the composite ...
Rezension
[Rezension zu:] Imbusch, Peter (Hrsg.): Soziologie der Hinterhältigkeit. Weinheim/Basel: Beltz Juventa 2021. 364 Seiten. ISBN: 978-3-7799-6548-0. Preis €29.95.
(2023-03-23)
Hinterhältigkeit wird alltäglich mit Haltungen wie Arglist, Gemeinheit, Falschheit, Niedertracht oder Tücke und mit entsprechend verpönten Handlungsorientierungen assoziiert, was mit eindeutigen moralischen Verurteilungen verbunden ist. Zu dieser selbstverständlich wirkenden normativen Einordnung heben Peter Imbusch und Joris Steg in ihrem einleitenden Beitrag des Sammelbandes den Widerspruch hervor, dass hinterhältiges Verhalten trotz seiner negativen Konnotation „ein häufig vorkommendes, alltägliches Phänomen“ (S. ...

Spatial patterns of urbanising landscapes in the North Indian Punjab show features predicted by fractal theory
(2022-02-02)
Understanding and governing human settlement patterns is a major challenge of the urban age. While rural settlements emerge as parts of agricultural landscapes, cities typically evolve in economically strategic locations, and over time form hierarchical systems of cities. Purposeful planning and the collective, self-organized behavior of the inhabitants interact in the development of regional settlement patterns. Since self-organizing systems often produce fractal patterns in nature, this study combines approaches ...

Experimental and numerical polarization analysis of the 3D transfer behavior in microsphere-assisted interferometry for 1D phase gratings
(2023-06-08)
Enhancing the lateral resolution in optical microscopy and interferometry is of great interest in recent research. In order to laterally resolve structures including feature dimensions below the Abbe resolution limit, microspheres in the optical near-field of the specimen are shown to locally improve the resolution of the imaging system. Experimental and simulated results following this approach are obtained by a high NA Linnik interferometer and analyzed in this contribution. They show the reconstructed surface of ...

Microbial biomass activity of a sodic Lixisol reclaimed with gypsum and clean water irrigation in urban vegetable systems of Burkina Faso
(2023-02-13)
Background: Little is known about the effects of gypsum application to remediate saline-sodic soils in the tropics and the role of microbial indicators in soil reclamation. Aims: Our study aimed at (1) remediating a highly weathered, irrigated sodic Lixisol under prolonged urban crop production by clean water and gypsum application and (2) to determine the remediation effects on soil microbial indices. Methods: A three-factorial on-farm experiment with maize (Zea mays L.) was used to study effects on soil microbial ...

“Reconstructionism”: A Strategy to Improve Outdated Attempts of Modernist Post‐War Planning?
(2023-02-23)
Recently, Germany has seen a series of inner‐city projects that tend to reconstruct pre‐war buildings or ensembles lost in the Second World War after demolishing earlier attempts to redefine the place in which they had been located with the means of modernist architecture. While those modernist buildings are often seen as “eyesores” by ordinary citizens advocating their demolition, the newer reconstructionist projects are criticized heavily by architects and planners not only because they often bring along revisionist ...

Aphyllophoroid fungi in insular woodlands of eastern Ukraine
(2017-12-22)
Background
Fungi play crucial roles in ecosystems and are among the species-richest organism groups on Earth. However, knowledge on their occurrence lags behind the data for animals and plants. Recent analyses of fungal occurrence data from Western, Central and Northern Europe provided important insights into response of fungi to global warming. The consequences of the global changes for biodiversity on a larger geographical scale are not yet understood. Landscapes of Eastern Europe and particularly of eastern ...

Long‐term vegetation changes in Nardus grasslands indicate eutrophication, recovery from acidification, and management change as the main drivers
(2020-07-08)
Questions
Which trends and patterns of community change occurred in Nardus grasslands over recent decades in parts of the Continental biogeographic region of Germany? Are patterns and trends consistent across two study regions? Do impacts of environmental changes on Nardus grasslands in Central Europe correspond to those identified in the European Atlantic biogeographic region?
Location
East Hesse Highlands, Germany.
Methods
In 2012–2015, we re‐surveyed quasi‐permanent plots that had been initially surveyed ...
