The clinical syndrome is associated with pathological findings including pneumonia, eosinophilic pneumonia, cryptogenic organizing pneumonia, acute fibrinous organizing pneumonia, and diffuse alveolar damage (DAD). Of these, the pathology most commonly associated with ARDS is DAD, which is characterized by a diffuse inflammation of lung tissue.
Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
Large-scale fossil fuel extraction can generate earthquakes. [ 49 ] [ 50 ] Induced seismicity can be also related to underground gas storage operations. The 2013 September–October seismic sequence occurred 21 km off the coast of the Valencia Gulf (Spain) is probably the best known case of induced seismicity related to Underground Gas Storage ...
The spatial scale of human activities and their related stressors can be difficult to define; activities can result in environmental impacts from a local scale (e.g., run-off) to a global scale (e.g., climate change). The range in spatial scales of environmental impacts of human activities makes it difficult to determine the appropriate scale ...
In fluid dynamics, the Hagen–Poiseuille equation is a physical law that gives the pressure drop in a fluid flowing through a long cylindrical pipe. The assumptions of the equation are that the flow is laminar viscous and incompressible and the flow is through a constant circular cross-section that is substantially longer than its diameter.
The filter kernel has an associated cutoff length scale and cutoff time scale . Scales smaller than these are eliminated from ϕ ¯ {\displaystyle {\overline {\phi }}} . Using the above filter definition, any field ϕ {\displaystyle \phi } may be split up into a filtered and sub-filtered (denoted with a prime) portion, as
Paternal transmission is almost always responsible for large repeat transmission resulting in the early onset of Huntington's Disease while maternal transmission results in affected individuals experiencing symptom onset mirroring that of their mother., [32] [34] While this transmission of a trinucleotide repeat expansion is regarded to be a ...
Orogenic uplift is the result of tectonic-plate collisions and results in mountain ranges or a more modest uplift over a large region. Perhaps the most extreme form of orogenic uplift is a continental-continental crustal collision. In this process, two continents are sutured together, and large mountain ranges are produced.
