Carbon dioxide may have a profound influence on the development of gas bubbles in the blood, a fresh doctoral study at the Norwegian School of Veterinary Science (NVH) has shown.
Decompression sickness can develop in both sports and professional divers if the diver surfaces too quickly and nitrogen in the blood does not have sufficient time to re-dissolve and distribute before the diver reaches the surface. Decompression sickness is a painful condition, which at worst may be life-threatening.Local production of CO2
The doctoral thesis of Henrik Rasmussen shows, however, that naturally-produced CO2 formed in the caecum of mice and rats is distributed through the entire intestinal wall, creating a state of localised supersaturation at various places in the caecum. Should these animals subsequently be given ultrasound contrast agents, which consist of gas bubbles administered intravenously, the gasses in these agents increase in size as a result of the gas supersaturation, causing damage to the caesium and liver.Consequences for North Sea divers?

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
