Disinfection
* destroys all the microorganisms in a certain environment except for spores.
* is accomplished by the addition of chlorine and ammonia
  - an integral part of disease prevention for both humans and animals
  - by the addition of sodium hypochlorite solution
  - done by chlorination
  - important in the prevention of eye infections
* is medical aid
  - care
  - much more effective on clean vehicles
  - needed because some bacteria and viruses can pass through filters
* is the final stage of secondary treatment
  - killing of microorganisms
  - minimum treatment for drinking water from a groundwater source
  - most important single factor in maintaining a pool which is safe and healthful
  - primary weapon against microbial risk
  - process by which chemicals are added to water to reduce bacterial contamination
  - selective destruction of pathogenic organisms
  - with chlorine and dechlorination is with sulfur dioxide
* kills bacteria in water.
* means essentially the same as sanitation
  - the destruction of disease-causing microorganisms
  - to remove or kill pathogens
* preventive procedure designed to kill disease-causing agents.
* protects against infectious disease by reducing the number of pathogens in the water.
* reduces the concentration of organisms to safe levels.
* uses ozonation and, particularly, chlorination to kill disease-causing microbes.
* utilizes chlorination through a serpentine tank.
* way of ensuring that drinking water is free from pathogens.

Discouragement
* can be the root of ineffectiveness as an individual.
* is an attitude and attitudes are always a choice
  - despair
  - deterrence
  - disapproval
  - one of mankind's worst ills
  - the opposite of faith
* means to lose heart.
* natural part of life.

Downie
* are the smallest of our resident woodpeckers.
* often camouflage the nest cavity entrance hole with moss, lichen and fungus.
* range in age from eighteen months to three years.

Dietary control
* is absolutely necessary for normal brain development.
* needs to be maintained throughout life.

Domination
* are the channel of mercy.
* exists where it is perceived.
* is about pleasure, a mutual pleasure
  - also characteristic of xenophobia, racism and nationalism
  - domination
  - social control
  - viewed as the appropriate role for men and subordination the role for women
* right, exploitation a contract, organisation an order of things.

Digitali
* can accumulate in tissues even when taken as prescribed
  - cause Cardiac arrhythmias if hypokalemia occurs
* directly decreases sinus automaticity only at high, toxic, concentrations.
* slows the pulse and slows the conduction of nerve impulses in the heart.

Defibrillation
* Most defibrillation occurs externally with paddles placed against the chest.
* can restore the heart's normal rhythm if it's done within minutes of the arrest.
* causes simultaneous depolarization of all Cardiac muscle fibers.
* consists of high-energy shock impulses.
* critical link in the chain of survival for treating cardiac arrest.
* is an essential component of effective emergency cardiac care.
  - the electric shock applied to restart a non-beating heart
* is the key to survival from a cardiac arrest
  - surviving a cardiac arrest
  - most effective treatment for ventricular fibrillation
* is the only effective treatment for cardiac arrest
  - of ventricular fibrillation
  - proven therapy to restore a normal heartbeat after cardiac arrest
  - way to solve cardiac arrest
* only works when the animal s heart has stopped.
* serves to depolarize the majority of the myocardial muscle mass.
* shocks a chaotic cardiac rhythm, without a pulse, back into a regular pulsing rhythm.
