momentum equation
200
momentum equation equation in hydrodynamics which formulates the equations of
motion as a relation that expresses the conservation of momentum in a
moving fluid subject to different forces.
Monera (syn. Prokaryota) one of the five kingdoms of living organisms. It includes
the Archaebacteria, Bacteria and Cyanobacteria. These mostly unicellular organisms
are characterized by their prokaryotic cell. Cyanobacteria can be multicellular.
monitoring the process of repetitive observation, for defined purposes, of one or
more elements of the environment, according to prearranged schedules in
space and time and using comparable methodologies for environmental
sensing and data collection. Monitoring provides factual information concerning the present state and past trends in environmental behavior (this
definition is based on the definition of monitoring accepted by the Governing Council of the United Nations Environmental Programme, UNEP). Biological monitoring has a public health objective (e.g., heart rhythm, activity of
kidneys, lead concentration in human hair or finger nails). Both environmental and ecological monitoring are concerned with the natural environment (excluding human beings): its ecological, physical, and chemical characteristics. Environmental monitoring primarily deals with the recording of
physical and chemical entities in the environment; sometimes the term is
used for the registration of physical stress on biota or - by using indicators - the
detection of trends induced by harmful substances. Exposure monitoring, the
recording of total exposure to critical receptors, is therefore a member of the
environmental monitoring family. Ecological monitoring is focused on the
recording of changes in ecological entities to determine trends in pollution or
the extent of contamination, geographical distribution, community composition etc. Two terms often used in connection with monitoring are bioassay
and indicator.
monoclonal antibody an antibody secreted by immune cells derived from just one
original antibody-forming cell. These cells are isolated and replicated by
cloning techniques. The high specificity of monoclonal antibodies is used
to detect the antigen isolated in e.g. sediment, water, cells or even fossils.
Monoplacophora class of the phylum Mollusca. Primitive snails that have retained
some segmentation traces from a supposedly segmented worm-like ancestor. The nap-like shell is thin, and the few recent species known to men live
in the deep sea. Example: Neopilina.
Monothalamia (syn. Monothalmida) Foraminifera with non calcareous, singlechambered test. The pseudopodia are rarely reticulate and the protoplasma
does not extend as a layer over the tests. Only some of the species are
marine. Example: Trichosphaerium.
