Element number three in our series of International Year of the Periodic Table graphics, made in partnership with the Royal Society of Chemistry, is beryllium. Beryllium is found in the mineral beryl, varieties of which include emerald and aquamarine. As one of the lowest density metals, gold-plated beryllium was used to make the 18 mirrors of …
Perfect porridge can be a challenge. Too lumpy, too runny, too stodgy – unpalatable porridge is a sadly common phenomenon. Here, we look at how science can provide pointers on getting porridge-making right. Let’s start with the porridge basics. Oats are around 40–60% starch. Starch is a carbohydrate which forms granules made of amylose and …
This paper presents a thermal elastohydrodynamic lubrication (EHL) model for analyzing crowned roller lubrication performances under the influence of frictional heating. In this thermal EHL model, the Reynolds equation is solved to obtain the film thickness and pressure results while the energy equation and temperature integration equation are evaluated for the temperature rise in the …
Element number three in our series of International Year of the Periodic Table graphics, made in partnership with the Royal Society of Chemistry, is lithium. Lithium is one of only three primordial elements created by the Big Bang (along with hydrogen and helium, who we’ve already met). It’s also the element we have to thank …
How do you get protein database (PDB) information into Python? Have you ever tried to get PDB coordinate data into Python to either manipulate the atoms or perform chemical calculations? There are a few methods of importing. There is the ProDy (http://prody.csb.pitt.edu/) project. This project parses PDB files for use within the ProDy system so …
