There are many techniques used to measuring the metabolic rate, but there are only best method that…

cost and the time we spend during long space travel, stay in the cold, vacuum universe would let astronauts experience different kind of radiation. These radiation may be some ionized particles as electromagnetic waves traveling with high speed and energy. They could come from nearby stars or even from those that are light-years away. Some of them has higher permeability when they are transmitting in the vacuum. Astronauts’ over exposure to the radiation during the long-term space travel can…

In discussions of ignorance, one controversial topic was issued…

of these resources are finite including fossil fuels such as coal and oil. For the 21st century, coal, gas and oil are no longer recommended as we’re moving towards infinite renewable resources such as solar and wind power. The electricity and heat energy derived from these resources is used in our homes for every day uses such as cooking, lighting, air conditioning, refrigeration etc (see…
