Antecedent description and depiction of the recently described cetacean behaviour of trap/tread-water feeding inferred from a nineteenth-century sighting of a ‘sea monster’ in the Gulf of Suez, Egypt

open access: yesNatural History Sciences
In 2017 and 2018, two groups of biologists published papers in which they independently described what was referred to as a ‘novel’ or ‘new’ feeding behaviour for cetaceans. Called ‘trap’ or ‘tread-water’ feeding, the behaviour was of interest as it was

Serotonin depresses feeding behaviour in ants

open access: yesJournal of Insect Physiology, 2012
Feeding behaviour is a complex functional system that relies on external signals and the physiological state of the animal. This is also the case in ants as they vary their feeding behaviour according to food characteristics, environmental conditions and - as they are social insects - to the colony's requirements.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Practical implications of increasing 'natural living' through suckling systems in organic dairy calf rearing [PDF]

open access: yes, 2007
The introduction of suckling systems in organic dairy calf rearing has the potential to enhance animal welfare in terms of ‘natural living’ and to live up to consumers’ expectations about organic agriculture.

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection

open access: yesAdvanced Engineering Materials, EarlyView.
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

FEEDING BEHAVIOUR OF CROSSBRED LARGE WHITE YORKSHIRE PIGS UNDER DIFFERENT FEEDING REGIMES [PDF]

open access: yesJournal of Veterinary and Animal Sciences, 2010
A trial was conducted to document the feeding behaviour of crossbred Large White Yorkshire pigs under different feeding regimes. A total of 32 weaned crossbred (75 per cent) Large White Yorkshire piglets were selected at random comprising of eight ...
