Hive It is the structure used by bees for a home.
Honey bees (Apis mellifera) They are completely domesticated and live in hives
provided by humans for the purpose of production of honey, however, they will
leave these hives and form “wild” colonies in hollow trees, but there are no wild,
native bees known. The castes of bees are: drones (sexually active males), a single
queen (the egg-laying female), and workers (sexless females). The worker honey
bees visit flowers to obtain nectar and pollen as their food, and construct the waxy
combs made from secretions of the wax glands. The worker bees tend the eggs
and larvae as well as feed the queen and carry away the eggs produced by the
queen.
Honey crop It is the amount of honey produced per bee colony per season.
Hormone A hormone is any member of a class of signaling molecules, produced by
glands in multicellular organisms, that are transported by the circulatory system
to target distant organs to regulate physiology and behavior.
Horsepower continuous duty rate It is as the term implies, the horsepower which
can be supplied continuously (24 hours per day) by an engine without
overheating.
Humanitarian engineering A new engineering branch focuses on programs that
are affordable, sustainable, and based on local resources, and it involves the
creation and application of the innovative methods, processes, systems, and
infrastructures to improving the well-being of marginalized people and disadvantaged communities, usually in the developing world. The word of “humanitarian”
has been defined as “concerned with or seeking to promote human welfare.”
Humanitarian technology A new professional field focuses on programs that are
affordable, sustainable, and based on local resources, and it involves mainly
application of the already developed simple methods, processes, systems, and
infrastructures to improving the well-being of marginalized people and disadvantaged communities, usually in the developing world. Examples of humanitarian
technologies for developing communities include affordable: (a) Technologies
for clean water and sanitation; (b) Nonpolluting lighting, heating, and cooking
methods; (c) Off-grid electricity generation (e.g., solar or bicycle);
(d) Agricultural technologies and methods (e.g., aquaponics or irrigation);
(e) Healthcare technologies; (f) Shelters; and (g) international STEAM education
of Science, Technology, Engineering, Arts and Mathematics.
Hurricane A tropical storm with winds of 74 miles per hour or more. Hurricanes
form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and eastern
Pacific Ocean.
Hydraulic dredging It is a floating barge type machine known as a cutter suction
dredge used to remove underwater materials and transfer those sediments mixed
with water (referred to as a slurry) through a pressurized pipeline to a deposit
location.
Hydraulic retention time (HRT) The given time it takes wastewater, including
any return flows, to pass through a certain area
Hydrocarbons Substances containing only hydrogen and carbon. Fossil fuels are
made up of hydrocarbons.
