aerotherapy, aerotherapeutics
Treatment of disease by fresh air, by air of different degrees of pressure or rarity, or by air medicated in various ways.
aerothermodynamics
1. Pertaining to the thermodynamic effects of air and other gases.
2. The branch of dynamics dealing with the study of the relationship between heat and mechnical energy in air and other gases.
3. The study of the relationship of heat and mechanical energy in gases, especially air.
aesthetics, esthetics (noun) (a plural form used as a singular)
1. The study, or philosophy, of beauty: Shannon enrolled in the university program for aesthetics, planning to become an art critic.
2. The study of what is considered beautiful, harmonious, and cultured: Nathaniel, the theater critic, commented on the aesthetics of the play, noting the balance and harmonious nature of the characters.

2. Specifically, the relationship between energy in the form of food produced and the energy input required to achieve this production.
agricultural mechanics
Using principles of mechanics for agricultural purposes; such as, in the development of equipment including automated feed mixers and other machines.
agrigenetics
Biotechnical research in plant breeding; the attempt to control plant evolution by genetic manipulation and gene splicing to provide desirable new varieties; such as, a (still experimental) strain of wheat with the soybean's capability of fertilizing its roots with airborne nitrogen.

Agrigeneticists have produced such new agricultural items as a redder, less watery commercial tomato and disease-resistant sugar cane.

agronomics
The science of the distribution and management of land.
allelochemics, allelochemic
1. Chemical interactions between species, involving release of active chemical substances; such as, scents, pheromones, and toxins.
2. A secondary substance produced by an organism that has the effect of modifying the growth, behavior or population dynamics of other species, often having an inhibitory or regulatory effect.
allesthetics, allaesthetics (noun) (plural form used as a singular)
Physical conditions whereby there are disorders of sensations in which stimuli are perceived as at points on the body that are in fact completely away from the points being stimulated: Mark decided to specialize in the neuroscience area of allesthetics, hoping to work with victims who are not able to determine where feelings of touches are actually located.
