Cleaner organisms exhibit a remarkable natural behaviour where they consume ectoparasites attached to "client" organisms. While this behaviour can be utilized as a natural method of parasitic disease control (or biocontrol), it is not known whether cleaner organisms can also limit reinfection from parasite eggs and larvae within the environment. Here we show that cleaner shrimp, Lysmata amboine...

A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.

Cleaner technology is central to sustainable development. It has the potential, at least in some industries, to reduce environmental impacts whilst enabling economic growth. Indeed, cleaner technology can be seen as resource efficiency, enabling firms to become both cleaner and more competitive at the same time. In contrast, conventional ('end-of-pipe') treatment imposes costs on society which ...

Enhanced thermal conductivity of nanofluids has proven importance in enhancing heat transfer for many application. In this study, graphite nanopowder dispersed water at different temperatures was studied experimentally. Stable concentrations (0.2 vol%, 0.5 0.8 1 vol% and 1.5 vol%) are prepared using ultrasonic cleaner by sonicating 3 hour. Thermal measured from temperature 25 to 55 ºC with an i...

In this paper we report our study on the user experience of robot vacuum cleaner behaviour. How do people want to experience this new type of cleaning appliance? Interviews were conducted to elicit a desired robot vacuum cleaner personality. With this knowledge in mind, behaviour was designed for a future robot vacuum cleaner. A video prototype was used to evaluate how people experienced the be...

What are the mechanisms that prevent partners from cheating in potentially cooperative interactions between unrelated individuals? The cleaner fish Labroides dimidiatus and client reef fish both benefit from an interaction as long as the cleaner eats ectoparasites. However, the cleaner fish prefers some client mucus, which constitutes cheating. Field observations suggested that clients control ...

Signals transmit information to receivers about sender attributes, increase the fitness of both parties, and are selected for in cooperative interactions between species to reduce conflict [1, 2]. Marine cleaning interactions are known for stereotyped behaviors [3-6] that likely serve as signals. For example, "dancing" and "tactile dancing" in cleaner fish may serve to advertise cleaning servic...
