Trail pheromone deposition from an organism is correlated with its environment. In the event where a food source is identified and a trail pheromone is deposited, certain wildlife may flock towards or away from the trail causing temporary or dispersal of the population or individual. With relocation of wildlife, surrounding plant life may ...

Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
Atomic layer deposition (ALD) is a thin-film deposition technique based on the sequential use of a gas-phase chemical process; it is a subclass of chemical vapour deposition. The majority of ALD reactions use two chemicals called precursors (also called "reactants"). These precursors react with the surface of a material one at a time in a ...
Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores. The diameter of the pores can be as low as 5 nanometers and as high as several hundred nanometers, and length can be controlled from few ...
Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. [1] Bioaccumulation occurs when an organism absorbs a substance faster than it can be lost or eliminated by catabolism and excretion.
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust (for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. [ 1 ] [ 2 ] The three most common types are asbestosis , silicosis , and coal miner's lung . [ 3 ]
It may be difficult to associate a particular case of diarrhea with a recent wilderness trip of a few days because incubation of the disease may outlast the trip. Studies of trips [ 2 ] [ 20 ] that are much longer than the average incubation period, e.g. a week for Cryptosporidium and Giardia , [ 9 ] [ 10 ] are less susceptible to these errors ...
