Sias University has an east–west focus, as seen in its architecture, funding, and ownership. The Sias campus was designed by Peter Weiss, an associate professor at Auburn University and his partner Charles Martin. They have designed over 80 buildings and are the only Americans to design a college campus in China. [3]
An A* grade was added in 2008 as a replacement of the advanced extension awards (AEA). The A* grade is only obtainable in the A2 level. For all subjects this requires a student to obtain 80% of all the UMS available in addition to 90% of the UMS available in the A2 modules.
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
Grading in education is the application of standardized measurements to evaluate different levels of student achievement in a course. Grades can be expressed as letters (usually A to F), as a range (for example, 1 to 6), percentages, or as numbers out of a possible total (often out of 100).
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Three dimensionality is best highlighted by the depictions of bonds, using wedges, bolding, and hashed formats. Some artists highlight three-dimensionality by varying fonts sizes, e.g. slightly larger fonts for the "front" atoms. In organic chemistry, double bonds and C-H bonds are shorter than most single bonds.
