ENTAMEBA HISTOLYTICA
A parasitic micro organism, found in sewage, which causes amebiasis.
A parasitic micro organism, found in sewage, which causes amebiasis.
Heat content; a thermodynamic property of a system defined as H = U + PV, where H is enthalpy, U is the internal energy of the system, P is the pressure exerted on the system by its environment, and V is the volume of the system.
The sum of all external conditions affecting the life of an organism.
Conditions other than indoor air contaminants that cause stress, comfort and/or health problems (e.g., humidity extremes, drafts, lack of air circulation, noise and overcrowding).
The potential adverse environmental effect of the release of a material into the environment.
The hazardous effect that a given compound or chemical has on the environment (soil, water, air) observed during environmental tests on the effects of the substance on aquatic and plant life.
Widespread outbreak of a disease.
The science that deals with the study of disease in a general population (e.g., Kawasaki Syndrome). Determination of the incidence (rate of occurrence) and distribution of a particular disease (by age, sex or occupation).
(EMC) – The condition in which the moisture content of a structural material has stabilized in relation to relative humidity and temperature of surrounding air; i.e., no change in moisture content as absorption and evaporation are continuing at the same rate
(ERH) – The ERH is the relative humidity of the air when it is in equilibrium with the built environment (i.e., the air is neither gaining moisture from, nor losing it to the material; or the point at which a hygroscopic material and the air within it contain the same amount of vapour)
