Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...
Nitrogen pollution can cause eutrophication, especially in lakes. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. Subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may ...
A 2021 study found that exposure to pollution causes an increase in violent crime. [59] A 2019 paper linked pollution to adverse school outcomes for children. [60] A number of studies show that pollution has an adverse effect on the productivity of both indoor and outdoor workers. [61] [62] [63] [64]
The current version 5.0 was released on November 27, 2017. Many clinical trials, now extending beyond oncology, encode their observations based on the CTCAE system. It uses a range of grades from 1 to 5. Specific conditions and symptoms may have values or descriptive comment for each level, but the general guideline is: 1 - Mild 2 - Moderate 3 ...
Water warming effects, as opposed to water cooling effects, have been the most studied with regard to biogeochemical effects. Much of this research is on the long term effects of nuclear power plants on lakes after a nuclear power plant has been removed. Overall, there is support for thermal pollution leading to an increase in water ...
The greenhouse effect on Earth is defined as: "The infrared radiative effect of all infrared absorbing constituents in the atmosphere.Greenhouse gases (GHGs), clouds, and some aerosols absorb terrestrial radiation emitted by the Earth's surface and elsewhere in the atmosphere."
A proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause (or distal cause) which is usually thought of as the "real" reason something occurred. The concept is used in many fields of research and analysis, including data science and ...
The effect of pesticides on soil microorganisms is impacted by the persistence, concentration, and toxicity of the applied pesticide, in addition to various environmental factors. [70] This complex interaction of factors makes it difficult to draw definitive conclusions about the interaction of pesticides with the soil ecosystem .
