All plants are producers, or autotrophs, which means they create their energy (or food) through a process called photosynthesis. In this lesson, we characterize producers by 3 main traits: producers make their own food; producers cannot physically move; and producers provide food and shelter for animals.
The Emergency Severity Index (ESI) is a five-level tool for use in emergency department (ED) triage. Experienced ED nurses use the ESI to rate patient acuity, from level 1 (most urgent) to level 5 (least resource intensive). The ESI is unique among triage tools, by including both acuity and resource needs in the system of categorizing ED patients.
Electromagnetic sensitivity (ES) is a progressive disabling disease associated with exposure to electronic equipment. While researchers have been aware of this disease for more than two decades (Dodge, 1970), ES has received little attention from the scientific community. It has many names: electrical sensitivity, electrical-hypersensitivity, electrically injured, electrical intolerance, electric allergy and electromagnetic sensitivity. Several million people all over the world suffer from ES. Some people with severe ES are unable to work. Compounding the medical problems is the uncertainty as to whether the
