And as Smart says, this sort of grading is no different than the sort of grading involved in judging one apple to be better than the others on the grocer's stand.
(An A+ security grade involves hashing passwords with complex cryptographic functions, salting them, hashing the result again and storing those credentials on separate, secure Web servers where hackers cannot easily break in).
A torn calf muscle in this grade involves 15-90% of the muscle's fibers.
You might learn the shocking results of an experiment by Ms. Creedon's third-grade class involving mold -- does it grow faster on plain bread, bread soaked in water, bread that's been dragged across the floor or bread that's been spit on?
Patients presented with intractable dyspepsia and esophagogastroduodenoscopy showed diffuse nodular lesions of varying grades involving postbulbar duodenum.

For drusen, such grades involve a change in morphology, number, drusen type, location, size and area covered, whereas for pigmentary changes differences in size and location are assessed.
Higher tumour nuclear grade, involved margins (<1 mm) and higher patient age (⩾50 years) were independently associated with an increased risk of recurrence at 5 years (Table 3).
There were no statistically significant associations between GSTM1-null genotype and the parameters analysed: age, menopausal and hormonal status, clinical and pathological tumour size, grade, involved nodes and p53 gene mutations.
Future work on in-vivo experimental reflectometry of various burn grades, involving both acute and survival studies, is necessary to further advance the potential clinical application of terahertz spectroscopy in burn diagnosis.
