Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

open access: yesSmall, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Ethological investigation on moulting laying hens in organic farming [PDF]

open access: yes, 2005
Introduction Organic egg farmers mainly rely on the same hybrids, breeding techniques and production schemes as conventional egg producers. This includes annual replacement of the laying hens.

Innovation in the Spaces In‐Between: Creating the Nexus Between Human and Non‐Human Actors in Systemic Innovations

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT By combining theories of system thinking with a post‐humanist approach, we established a nexus between human and non‐human systems in the examination of systemic innovation. By doing so, we shed light on the interdependencies that exist between human and non‐human systems and contribute theoretically as well as methodologically to theories on ...

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Mentoring matters to early‐career veterinarians' confidence, clinical growth and career retention: A qualitative interview study

open access: yesVeterinary Record, EarlyView.
Abstract Background Veterinarians in clinical practice, especially early‐career veterinarians and those identifying as women, have higher levels of negative mental health outcomes compared to the general population. Partnering with a mentor can mitigate some of the work‐related challenges that may contribute to poor mental health and career attrition ...

A Study of a Method to Predict Printing Quality of Paper by Means of Smoothness and Elongation Test Results [PDF]

open access: yes, 1961
The object of this thesis is to investigate the use of smoothness and elongation test results as criterion for evaluating the printing quality of paper. The relationship of smoothness and printing quality has been known for many years and in all previous

\u3cem\u3eDrosophila\u3c/em\u3e Vitelline Membrane Assembly: A Critical Role for an Evolutionarily Conserved Cysteine in the “VM domain” of sV23 [PDF]

open access: yes, 2010
The vitelline membrane (VM), the oocyte proximal layer of the Drosophila eggshell, contains four major proteins (VMPs) that possess a highly conserved “VM domain” which includes three precisely spaced, evolutionarily conserved, cysteines (CX7CX8C ...
