Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
This missing matter — which is different from dark matter — is composed of baryons, the particles, such as protons and electrons, that are found on the Earth,…
Physicists at McGill University have developed a system for measuring the energy involved in adding electrons to semi-conductor nanocrystals, also known as…
The homeless star is on the outskirts of the 30 Doradus nebula, a raucous stellar breeding ground in the nearby Large Magellanic Cloud. The finding bolsters…
Discovered in 1948, Casimir forces are complicated quantum forces that affect only objects that are very, very close together. They’re so subtle that for most…
Stars are born in dense clouds of dust and gas that can now be studied in unprecedented detail with Herschel. Although jets and winds of gas have been seen…
A super-massive black hole acts like a lurking “monster” at the centre of the galaxy which swallows the surrounding material through the intensity of its…

Seit einigen Jahren unternehmen Forscher Anstrengungen, um Lösungen zu finden, wie supraleitende, ferroelektrische und ferromagnetische Oxide strukturiert werden können, ohne dabei die intrinsischen Eigenschaften der Materialen zu verändern.
Sächsischen Wissenschaftlern ist es nun gelungen, ein einfaches nasschemisches Verfahren zu entwickeln, mit dem genau dieses Ziel erreicht wird. Neben der einfachen Ätzung, steilen Ätzkanten für nm-Strukturen ist es auch möglich, multi-layer zu strukturieren.
Sie haben Zweifel? Dann stellen Sie uns auf die Probe! Wir ätzen Ihnen die gewünschte Struktur mit unserem Verfahren.
Since precision farming is a today's requirement for economical agriculture it is required to map the harvested crops per field independent on moisture level within the crops.
We present a solution that is able to determine output rate with respect to mass and volume, while the machine is harvesting across the field in real time.
The whole unit is integrated (plug-in) within the crops flow inside the harvester. The apparatus guaranties a continuous recording of density, mass and volume and is suitable for a wide range of harvested crops. It will precisely work even if the machine moves over the rough field. To be sure what you have got on the end of the day it calibrates itself and comes with an automatic error control.
Since precision farming is a today's requirement for economical agriculture it is required to map the harvested crops per field.
We present a solution that is able to determine volume and mass while the machine is harvesting across the field in real time. It automatically adopts to all kind of crops.
The measurement unit is integrated within the crops flow inside the harvester. The construction avoids measurement errors due to sticking moistures crops and allows continuous recording of volume, mass and density.
