Thin clay beds, which have a large storage capacity for dissolved and sorbed contaminant mass, are common in many types of sandy aquifers.
In practice, the use of beams with varying sectional properties, such as inertia, area and mass is common, and to estimate the natural frequencies of these beams the engineer has to resort to more expensive methods such as the finite element method.
Low bone mass is common in end-stage renal disease patients, especially those undergoing hemodialysis.
Multiple chronic conditions and low skeletal muscle mass are common features of aging that are detrimental to physical performance.
As loss of body weight or skeletal muscle mass is common in older persons, inadequate intake of protein and energy may result in clinically relevant reductions in strength, exercise capacity and mobility [ 102].
The use of skeletal scaling to estimate body mass is common in extinct mammals and birds (for example, [ 17, 41, 42, 45, 98]); however, it is less common in extinct non-avian archosaurs and non-mammalian synapsids ([ 48, 73, 99] being notable exceptions).
As expected many masses were common to all contaminated and control blood cultures, most probably representing haemoglobins and other blood components.
Non-hyperfunctioning adrenal masses are common in patients with cancer.
Tuberculosis predominantly affects the thoracic spine; paravertebral masses are common, but new bone formation is unusual.
Large, homogeneous masses are common, and calcification is very rare in untreated patients.
