### cleaning | sanitation:

Ecological sanitation
* based on biogas technology can turn human and animal excreta into energy.
* is based on natural ecosystems.

### cleaning | sanitation:

Good sanitation
* does decrease the risk of some diseases.
* helps prevent many diseases.
* including soil sterilizations helps to control nematodes.
* involves the removal of old grain and dust in and around the gain bin
  - and dust in and around the grain bin
* is especially important for trees infected with anthracnose
  - essential in reducing disease problems
* is important for preventing mastitis in goats in milk
  - in reducing disease occurence in nurseries
  - most important within and immediately adjacent to trees that are to be protected
* is the best and most economic way to control rats
  - first step to controlling the spread of bed bugs
* limits rodents' sources of food and shelter.

Proper sanitation
* can reduce insect pests significantly
  - the risk of many diseases
* increases the quality of cider and prolongs shelf life.
* is an important step in controlling house mouse populations
  - critical in lice control
  - essential since the infective organism is transmitted via manure
* is the key to any type of long range pest control
  - the elimination of tapeworm infestation worldwide
  - vital to keeping pets healthy, and shelters face unique sanitation challenges

### cleaning | scrub:

Coastal scrub
* can be treeless.
* is low, dense, dry forest near the coast.

Scrub typhus
* cause of fever in regions of Asia and the Pacific.
* is an infectious disease
  - caused by the parasite Rickettsia tsutsugamushi
  - bacterial infection
* is common in east Asia and the west Pacific
  - eastern Asia
  - most common in east Asia and the western Pacific
* occurs in the Asiatic-Pacific area bounded by Japan, India, and Australia.
* serious disease for military personnel.

### clear weather:

Sunny location
* are clear weather
  - natural things
* have air movement
  - drainage
* have good air movement

### clear, colorless gas:

Butane
* Refers usually to a mixture of isobutane and normal butane.
* clear, colorless gas.
* comes in disposable tanks
  - low pressure cartridges
* common fuel source for cooking and heating.
* decidedly low-tech way to power nanosatellite thrusters.
* has four carbon atoms chained together
  - molecules, so it's heavier than propane
  - more than one, and the number of energy minima goes up rapidly with molecular size
* is alkane
  - chemical compounds
  - gases
  - highly flammable
  - light, clean and requires no pumping or priming to produce an instant flame
  - lighter fluid
  - paraffin
  - sniffed to get high, much like sniffing gasoline or paint
* is sold in canisters , for cooking and camping
  - and is typically already pressurized
  - the first alkane to have isomers
* is used as a fuel in lighters
  - an energy source by a number of bacteria
  - in cigarette lighters
* tasteless, odorless fuel, perfectly suited as a lighter medium.
* turns into a liquid when put under pressure.
+ Butane, Dangers
  * Butane is dangerous. Inhalation can lead to death by asphyxiation. Contact with the skin can lead to frostbite. If the liquid comes in contact with the air, it will explode
  - Uses of Butane: Fuel
  * Butane is sold in canisters, for cooking and camping. It is also used as fuel in cigarette lighters, and as propellant in aerosol sprays or deodorants. Some kinds of Butane are used in refrigerators

### clearly innermost | cytoplasmic body part:

Membrane
* Cytoplasmic membrane is clearly innermost
  - only unit membrane system of majority of prokaryotes
* Some cytoplasmic membranes result in leakage.
