### infectious condition:

Chronic bronchitis
* alters the pattern of aerosol desposition in the lung.
* can be a serious disease and very debilitating
  - life-threatening
  - develop from repeated exposure to chemicals that irritate the lungs
  - injure cilia action and increase the risk for bacterial infection
  - last for months and is usually caused by smoking or environmental pollution
  - lead to emphysema - another lung disease
  - occur alone, or with emphysema
  - overlap with clinical features of emphysema and bronchial asthma
* can progress to a life-threatening lung disease, emphysema
* common ailment for smokers.
* consists of chronic cough for most of the days in a few months out of the year.
* involves coughing up mucus nearly every day for months or years.
* is also more common in women, than men
  - an infectious condition
* is an inflammation and eventual scarring of the lining of the bronchial tubes
  - inflammation, or irritation, of the airways in the lungs
  - basically a preventable disease being rare in the non-smoker
  - bronchitis
  - caused by small abnormalities in the airways
  - mainly a disease of smokers
  - persistent inflammation of the bronchial mucosa
  - the seventh most prevalent of all chronic conditions
  - thought to be very common, predominantly among cigarette smokers
  - usually the result of many bouts of acute bronchitis
* lasts three months or more, and symptoms can return year after year.
* long-term condition of excessive bronchial mucus with a productive cough.
* lung disease caused primarily by smoking and pollution.
* occurs when the bronchial tubes in the lungs become inflamed.

### infectious disease emergency:

Gas gangrene
* can occur in a wound where certain bacteria are present
  - and worsen deep-tissue wounds
* form of wet gangrene.
* is an infectious disease emergency
  - associated with war wounds, auto accidents, and septic abortions
  - progressive and often lethal
* produces pain and swelling as the infected area bloats with gas.

Infectious organism
* Many infectious organisms can cause it.
* are frequent culprits in fading kitten syndrome
  - prevalent around barns, corrals, and fences
* can flourish anywhere in the urinary tract.

Inference
* also describe the mapping between task oriented roles and domain level entity types.
* are judgments made or conclusions drawn based on what happened
  - opinions based on fact
* are statements about the unknown based on the known
  - unknown, made on the basis of the known
  - the core of comprehension
* bases upon knowledge.
* constitutes optimization on the curved geometry of Lie manifolds.
* detects the existence of statistical spatial relationships from data.
* draws from evidence
  - other evidence
* is based on the fuzzy accessibility relations between worlds
  - essential to, and part of, being human
  - reasoning
  - the interpretation of facts
* is the process of creating new information based on a set of underlying facts
  - deriving logical consequences from assumed premises
  - recognizing the relationship between two terms, concepts, or ideas
  - type inference
  - used for understanding
  - viewed as a process of propagation of elastic constraints
* logical conclusion from given facts.
* requires information.
