Salton
Sea : the name 'Salton', apparently coined from 'salt',
was first given in 1853 to the Southern Pacific station and then in
1892 transferred to the ancient lakebed previously called Lake
Cahuilla for the Indians of the region. The name was then retained
in the 'Salton Sea' for the sheet of water (much smaller than the
old lakebed) that formed in 1907 after the overflow of the Colorado
River.

SAMPA : Speech
Assessment Methods Phonetic Alphabet : a machine-readable
phonetic alphabet. SAMPA basically consists of a mapping of symbols
of the International Phonetic Alphabet (IPA) onto ASCII codes
in the range 33..127, the 7-bit printable ASCII characters.
Associated with the coding (mapping) are guidelines for the
transcription of the languages to which SAMPA has been applied. A
SAMPA transcription is designed to be uniquely parsable. As with the
ordinary IPA, a string of SAMPA symbols does not require spaces
between successive symbols. In its basic form SAMPA was seen as
catering essentially for segmental transcription, particularly of a
traditional phonemic or near-phonemic kind. A proposal for an
extended version of the segmental alphabet, X-SAMPA, extends the
basic agreed conventions so as to make provision for every symbol on
the Chart of the International Phonetic Association, including all
diacritics. In principle this makes it possible to produce a
machine-readable phonetic transcription for every known human
language.
Where Unicode (ISO 10646) is not available or not appropriate,
SAMPA and the proposed X-SAMPA (Extended SAMPA) constitute the best
robust international collaborative basis for a standard
machine-readable encoding of phonetic notation.

Santa
Rosa : the name was extremely popular for naming
geographical items in California: city, river, creek, island, hill ,
mountain, etc. Most places were doubtless named for the Dominican
St. Rose of Lima (1586-1617), until recent times the only female
saint of the Americas, but some may have been named for the Italian
Franciscan St. Rose of Viterbo (1235-1253).

saturation
(or purity of color) : strength or purity
of the color; the intensity of a specific hue: the amount of gray in
proportion to the hue, measured as a percentage from 0% (gray) to
100% (fully saturated); on the standard color wheel, saturation
increases from the center to the edge; used as a parameter in the
HSB color model. The saturation of a color is determined by a
combination of light intensity and how much it is distributed across
the spectrum of different wavelengths. With no saturation at all,
the hue becomes a shade of gray; the purest color is achieved by
using just one wavelength at a high intensity such as in laser
light.

seawater
: salinity : a convenient physical parameter, which is defined

The value of salinity is roughly
equal with the mass of dissolved compounds, expressed in grams per
kilogram of seawater, while the definition in terms of electrical
conductivity allows meaningful measurements. Salinity values in the
open oceans at mid latitudes typically fall between 34 and 36. |

of the radiation corresponding to the transition between the two

atom at rest at a temperature of 0 K.
The unit
of time, the second, was at one time considered to be the fraction 1/86
400 of the mean solar day. The exact definition of "mean
solar day" was based on astronomical theories. However, measurement showed that irregularities in the rotation of the Earth could
not be taken into account by the theory and have the effect that
this definition does not allow the required accuracy to be achieved.
An atomic standard of time interval, based on a transition between
two energy levels of an atom or a molecule, could be realized and
reproduced much more precisely. |

sense :
a system of sensory cells comprising (1) receptor cells that respond
to a specific kind of physical interaction with the environment, (2)
transfer cells that convey the response (signal) to a nervous center
(brain), and (3) set (region) of the brain cells where the signal is
received and interpreted. From the times of Aristotle, five human
senses are recognized: seeing (vision), hearing (audition), taste (gustation),
smell (olfaction), and touch (tactition). Current list adds sense of
heat (thermoception), sense of pain (nociception), sense of balance
(equilibrioception), and sense of body awareness (proprioception).
There is no consensus
amongst neurologists on the variety of senses: disputes arise with
regard to the classification of the sensory cells and their mapping
to regions of the brain. For example, some neurologists recognize
four different taste senses given that each receptor conveys signal
to a different region of the brain. Additionally, most neurologists
classify electroception and magnetoception as non-human (animal)
senses while some believe that those are stunted human senses also. |

particular context or group. Slang usually
involves deviation from standard language; it does not necessarily
involve neologisms, but often involves the creation of new
linguistic forms or the creative adaptation of old ones. Although
some slang expressions become commonly understood (e.g. 'cool'),
slang is primarily a tool for recognizing members of the same group,
and to differentiate that group from society at large. Compare

Slough
: In England the generic term was used for a muddy or miry place. In
America, in the Middle West, it came to designate any good-sized
backwater, and in California it took on the meaning of tidal creek,
estuary, river channel. The tidal channels of the San Francisco Bay
are often called sloughs, although on maps they may appear as
creeks. The generic term 'slough' is also used for the channels and
branches of the lower Sacramento and San Joaquin River systems, as
well as for channels in the Tulare Lake section, and in other
regions where similar hydrographic conditions prevail. In Los
Angeles Co. the name was given to two swampy lakes that have no
connection with the ocean or with a river. |

of the following years. The name is doubtless derived from a Patwin
word for 'nose', plausibly related to an Indian chief with a
prominent protuberance (named 'Chief Nose' by the Spaniards); the
interpretation 'valley of the moon' is more poetic but less
authentic. |

SPL : Sound
Pressure Level : an acoustic scale, expressed in decibels
(dB), where 0 dB (the threshold of hearing) corresponds to sound
pressure level of 20 µPa, the minimum detectable 1000 Hz sound pressure
level by average human ear; to avoid confusion with other decibel
measures, the symbol dB(SPL) is often used. On this scale, the
normal range of human hearing extends from about 0 dB to about 140
dB. A 10 dB increase in the level of a continuous noise represents a
perceived doubling of loudness; a 5 dB increase is a readily
noticeable change, while a 3 dB increase is barely noticeable to
most people. The threshold of pain is about 135 dB.
SPL
is an objective measurement of sound pressure and is independent of
frequency, while loudness is an apparent, subjective acoustic scale
which takes account of the variable human sensitivity to different
sound frequencies.
