Minimising insect mortality during grassland mowing: The potential of insect chasing devices

Insect Conservation and Diversity, Volume 18, Issue 6, Page 1086-1098, November 2025.
Insect chasing devices have a great potential to deter arthropods prior to mowing, thereby reducing mortality. The effectiveness of mechanical flushing bars is limited and depends on driving speed, vegetation structure and species composition. The blowing device is the most independent of external factors and therefore the most effective.

Mitigating Arthropod Mortality During Roadside Mowing: The Potential of the EcoCut Insect Flushing Bar

Journal of Applied Entomology, Volume 149, Issue 9, Page 1407-1417, November 2025.
ABSTRACT Due to their size and corridor function, roadside verges are of concern for the conservation and protection of insects and other arthropods. Any opportunity to manage them in an insect‐friendly way, for example, insect‐friendly mowing technology, should be seen as an important contribution. Here we investigated the effectiveness of the EcoCut (

Results of a Round Robin Test for the Determination of Polarization Resistances on Differently Weathered Zinc Samples Using Gel Electrolytes

Materials and Corrosion, Volume 76, Issue 9, Page 1294-1305, September 2025.
Whether a top layer of corrosion products on zinc or galvanized steel protects the metal from further corrosion can be determined by measuring the electrochemical corrosion product layer resistance using an agar gel as the test electrolyte. The test standard DIN 50023:2024‐07 has recently been published.

Minimization of Tikhonov Functionals in Banach Spaces

Abstract and Applied Analysis, 2008
Tikhonov functionals are known to be well suited for obtaining regularized solutions of linear operator equations. We analyze two iterative methods for finding the minimizer of norm-based Tikhonov functionals in Banach spaces. One is the steepest descent

Exploring Two Different Feeding Strategies During Dry Period With Regard to Dry Matter Intake, Intermediary Metabolism and Certain Health Aspects of Dairy Cows in Germany

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 5, Page 1073-1090, September 2025.
ABSTRACT Dry cow feeding plays an essential role in dairy production. Therefore, the objective of this study was to evaluate two different dry cow feeding strategies regarding dry matter intake (DMI), metabolism and health aspects of dairy cows in the first 50 days after calving.

Ist Phenylnitren ein fehlendes Bindeglied in der Bildung polyzyklischer aromatischer Stickstoffheterozyklen?

Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.
Ein neuer Bildungsweg für polyzyklische aromatische Stickstoffheterozyklen (PANH) wurde gefunden. Die Reaktion von Phenylnitren mit dem Propargylradikal führt zu Chinolin und belegt, dass Nitrene geeignete Vorläufer zum Einbau von Stickstoffheteroatomen sind.

On the Reduction of Ammonia from the Waste of Alpine Houses

Adsorption Science & Technology, 2005
An evaluation of the effectiveness of the cation-exchange resin Amberlite IR-120 (AMIR 120) for removing ammonia from aqueous solutions and waste was made. Two types of waste were obtained from houses located in the Alps and used in this work.
