Jelly biomass sinking speed reveals a fast carbon export mechanism

Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species o...

Sinking treasure

social engagements. With the Bologna system, everything is fitted to match a 40 hour per week work schedule for the entire year allowing only for 6 weeks of holiday and one week of illness. Many students are now protesting against this reduction of university to a school-like system. Students also protested against tuition fees, which have been introduced only recently in a break with a long tr...

Natural Heat-Sinking Control Method for High-Speed Actuation of the SMA

This paper describes two methodologies for increasing the actuation speed of the shape memory alloy (SMA) actuator in ambient environment. The first method involves the implementation of a simple, light-weight heat sink, which consists only of a combination of an outer metal tube with the silicone grease, but able to cool the heated alloy effectively. The second method describes a high current ...

That sinking feeling.

Y ou are doing a breast reduction. You have chosen a vertical flap and inverted T incision. You like the vertical reduction and medial pedicle because there is a shorter incision , but you think there will be too much skin excess, so it will be better to excise it now. For some reason, every time you do the inferior pedicle the base of the pedicle becomes thin and narrow. This worries you. You ...
