The health effects of tobacco had been debated by users, medical experts, and governments alike since its introduction to European culture. [1] Hard evidence for the ill effects of smoking became apparent with the results of several long-term studies conducted in the early to middle twentieth century, such as the epidemiology studies of Richard Doll and pathology studies of Oscar Auerbach.
A discontinuity may exist as a single feature (e.g. fault, isolated joint or fracture) and in some circumstances, a discontinuity is treated as a single discontinuity although it belongs to a discontinuity set, in particular if the spacing is very wide compared to the size of the engineering application or to the size of the geotechnical unit.
Integrated pulmonary index (IPI) is a patient pulmonary index which uses information from capnography and pulse oximetry to provide a single value that describes the patient's respiratory status. IPI is used by clinicians to quickly assess the patient's respiratory status to determine the need for additional clinical assessment or intervention.
The J-integral represents a way to calculate the strain energy release rate, or work per unit fracture surface area, in a material. [1] The theoretical concept of J-integral was developed in 1967 by G. P. Cherepanov [2] and independently in 1968 by James R. Rice, [3] who showed that an energetic contour path integral (called J) was independent of the path around a crack.
As tobacco smoking and high alcohol intake have been linked with osteoporosis, smoking cessation and moderation of alcohol intake are commonly recommended as ways to help prevent it. [ 122 ] In people with coeliac disease adherence to a gluten-free diet decreases the risk of developing osteoporosis [ 123 ] and increases bone density. [ 65 ]
The ISS is based (see below) upon the Abbreviated Injury Scale (AIS). To calculate an ISS for an injured person, the body is divided into six ISS body regions. These body regions are: Head or neck – including cervical spine; Face – including the facial skeleton, nose, mouth, eyes and ears; Chest – thoracic spine and diaphragm
The stress–strain index (SSI), of a bone, is a surrogate measure of bone strength [1] determined from a cross-sectional scan by QCT or pQCT (radiological scan).The stress–strain index is used to compare the structural parameters determined by analysis of QCT/pQCT cross-sectional scans to the results of three-point bending test.
The index was developed by Mary Charlson and colleagues in 1987, but the methodology has been adapted several times since then based on the findings of additional studies. [5] Many variations of the Charlson comorbidity index have been presented, including the Charlson/Deyo, Charlson/Romano, Charlson/Manitoba, and Charlson/D'Hoores comorbidity ...
