Topper in Prove: Rotor Powerfulness Glass

Though Rotor is trump known for marketing oviform concatenation rings, which they say addition superpower turnout by eliminating idle floater in the wheel virgule, what we same about almost the caller is their commonsensical, do-it-better coming. Their cranks fit about every bum bracket received usable (badly!), and they are sold in whole modular forge so you can buy lone what you need, be it cranks, concatenation rings, backside brackets, or any compounding. The new ANT+ compatible Rotor Superpower Chalk offers approximately of the virtually exact readings useable by embedding a striving bore Read more [...]

The rotor is made of two turns of DNA

A group of Japanese scientists has designed nanomotors working by changing the conformation of the DNA molecule - the transition from the double helix pravozakruchennoy (B-form) in the left-twisted (Z-form). "Run" is the motor by changing the concentration of ions in solution. Securing the motor in a rigid frame that fixes it to the substrate, not interfering with the rotation of the rotor, the scientists managed by atomic force microscopy to monitor the operation of the engine in real time. They fixed two turns of the rotor, which is one BZ-transition.Fig. 1. Top: scheme of rotation Read more [...]

Vetryachok Ugrinskogo

    Aboutdnazhdy in November-December elekstrichestvo completely ended, I realized that something has to be done quickly. I also realized that a powerful sail windmill I quickly did not collect.

Centrifugation

Centrifugation - a division of mechanical mixtures into their component parts by centrifugal force. Instruments used for this purpose is called centrifuges. The main part of a centrifuge rotor mount it nests for centrifuge tubes. The rotor rotates at high speed, so that creates sizeable centrifugal force, under which there is a division of mechanical mixtures, such as deposition of particles suspended in a liquid. Centrifuges: 1 - Manual 2 - electric.Clinical and hygiene laboratories centrifugation Used to separate the red blood cells from blood plasma, blood clots from whey, the liquid from Read more [...]
