Structural Biology Using Electrons and X-rays is the perfect book to provide advanced diploma-based techniques of structural biology. While concentrating on electron cryo-microscopy with image analysis, it also includes X-ray crystallography in a coherent survey of fundamental principles. Starting with Fourier transforms and progressing through optics and imaging Principles, symmetry and three-dimensional reconstruction theory, Structural Biology Using Electrons and X-rays ends in an account of the latest methods adapted this crystals, helices, viral heads, and single particles.
* Emphasis on common principles underlying all diffraction-based methods
* Thorough grounding in theory requires a simple algebra
* Visual representations and explanations of challenging content

When you see a hot rod car on the street, what first draws your eye? Is it the custom paint job, the shiny chrome details, the souped-up engine, or the body modifications that transformed a boring factory model into a beautiful supermodel ready for the auto show catwalk? Hot rods are personal automotive visions brought to life. UGears 70192

The Retro Car UGR-T is a stylish new addition to Ugears\' ever-growing collection of historic and modern cars, racers, motorbikes, trucks and other outstanding automotive DIY models.
This vintage model pays homage to the dawn of the automobile age.
Ugears\' team of engineers and designers have developed a special, classic car model to take you back to that age. Outstanding features include the functional convertible folding roof with fabric overlay; latching cab doors that open to the front; the hood that opens on both sides, revealing a functional 4 cylinder engine with crankshaft; a skeuomorphic pendulum that simulates the sound of a rumbling motor; front wheels that turn using the steering wheel; and a spare wheel mounted at the back.
