X-ray crystallography is by far the most widely used method to determine atomic-resolution structures of biopolymers but is limited to samples that form well-ordered, three-dimensional crystals.

Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...

This was a two-year research project (June 2003 - May 2005) under the ESRC Research Methods programme. The project involved the development of multilevel simultaneous equations models for the analysis ...

In some simultaneous equations neither the two coefficients of \(x\) nor the coefficients of \(y\) match. You will need to find numbers to multiply each equation by so that one pair of coefficients ...
