Jacob–Monod hypothesis The theory
postulated by the French biologists
François Jacob (1920– ) and Jacques
Monod (1910–76) in 1961 to explain the
control of *gene expression in bacteria
(see operon). Jacob and Monod investi-
gated the expression of the gene that
codes for the enzyme β-galactosidase,
which breaks down lactose; the operon
that regulates lactose metabolism is
called the *lac operon.

jade A hard semiprecious stone consist-
ing either of jadeite or nephrite. Jadeite,
the most valued of the two, is a sodium
aluminium pyroxene, NaAlSi2O6. It is
prized for its intense translucent green
colour but white, green and white,
brown, and orange varieties also occur.
The only important source of jadeite is in
the Mogaung region of upper Burma.
Nephrite is one of the amphibole group of
rock-forming minerals. It occurs in a vari-
ety of colours, including green, yellow,
white, and black. Important sources in-
clude Siberia, Turkistan, New Zealand,
Alaska, China, and W USA.

Jahn–Teller effect If a likely structure
of a nonlinear molecule or ion would
have degenerate orbitals (i.e. two molecu-
lar orbitals with the same energy levels)
the actual structure of the molecule or
ion is distorted so as to split the energy
levels (‘raise’ the degeneracy). The effect
is observed in inorganic complexes. For
example, the ion [Cu(H2O)6]

2+ is octahe-
dral and the six ligands might be ex-
pected to occupy equidistant positions at
the corners of a regular octahedron. In
fact, the octahedron is distorted, with
four ligands in a square and two opposite
ligands further away. If the ‘original’
structure has a centre of symmetry, the
distorted structure must also have a cen-
tre of symmetry. The effect was predicted
theoretically by H. A. Jahn and Edward
Teller in 1937.

jasper An impure variety of *chal-
cedony. It is associated with iron ores and
as a result contains iron oxide impurities
that give the mineral its characteristic
red or reddish-brown colour. Jasper is
used as a gemstone.

jaw The part of the vertebrate skeleton
that provides a support for the mouth
and holds the teeth. It consists of two
bones, the upper jaw (maxilla) and the
lower jaw (mandible). Members of the Ag-
natha lack jaws.

Jeans instability Instability in a cloud
of gas in space due to Ûuctuations in the
density of the gas, causing the matter in
the cloud to clump together and lead to
gravitational collapse. The conditions
under which this occurs were worked out
by Sir James Hopwood Jeans (1877–1946)
in terms of Newtonian gravity. The analo-
gous analysis of this problem using gen-
eral relativity theory is the basis of the
theory of *structure formation.

jejunum The portion of the mam-
malian *small intestine that follows the
*duodenum and precedes the *ileum.
The surface area of the lining of the je-
junum is greatly increased by numerous
small outgrowths (see villus). This facili-
tates the absorption of digested material,
which is the prime function of the je-
junum.

jelly�sh See cnidaria.

Jenner, Edward (1749–1823) British
physician, who is best known for intro-
ducing smallpox vaccination to Britain in
1796 (announced two years later), using a
vaccine made from cowpox.

jet A variety of *coal that can be cut and
polished and is used for jewellery, orna-
ments, etc.

jet propulsion (reaction propulsion)
The propulsion of a body by means of a
force produced by discharging a Ûuid in
the form of a jet. The backward-moving

Page 447

jet of Ûuid reacts on the body in which it
was produced, in accordance with New-
ton’s third law of motion, to create a reac-
tive force that drives the body forward. Jet
propulsion occurs in nature, the squid
using a form of it to propel itself through
water. Although jet-propelled boats and
cars have been developed, the main use of
jet propulsion is in aircraft and spacecraft.
Jet propulsion is the only known method
of propulsion in space. In the atmosphere,
jet propulsion becomes more efÜcient at
higher altitudes, as efÜciency is inversely
proportional to the density of the me-
dium through which a body is Ûying. The
three principal means of providing jet
propulsion are the turbojet, the ramjet,
and the rocket. The turbojet is an air-
breathing *heat engine based on the *gas
turbine, used to power jet aircraft. The
ramjet is also an air-breathing engine, but
compression of the oxidant is achieved by
the forward motion of the device through
the atmosphere. This enables the com-
pressor and turbine of the gas turbine to
be dispensed with and the remaining sys-
tem consists simply of an inlet diffuser, a
combustion chamber in which fuel is
burnt, and a jet nozzle through which the
products of combustion are discharged.
Used in guided missiles, the ramjet must
be accelerated to its operating velocity be-
fore it can Ûy (see also pulse jet). These
two forms of jet propulsion, being air-
breathing engines, can only be used in the
earth’s atmosphere. The *rocket, how-
ever, carries its own oxidant and can thus
be used in space. See also ion engine.

jet stream A narrow wind current that
occurs in the earth’s atmosphere above
the lower troposphere (see earth’s atmos-
phere). The wind Ûows towards the east at
speeds of between 60 km/h (summer) and
125 km/h (winter).

jeweller’s rouge Red powdered
haematite, iron(III) oxide, Fe2O3. It is a
mild abrasive used in metal cleaners and
polishes.

j-j coupling A type of *coupling in
many-fermion systems, such as electrons
in atoms and nucleons in nuclei, in which
the energies associated with the spin–
orbit interactions are much higher than
the energies associated with electrostatic

repulsion. *Multiplets of many-electron
atoms having a large atomic number are
characterized by j-j coupling. Multiplets in
the *shell model of nuclei characterized
by j-j coupling are invoked to explain the
*magic numbers of nuclei. The multiplets
of many atoms and nuclei are intermedi-
ate between j-j coupling and *Russell–
Saunders coupling (intermediate coupling).

joint The point of contact between two
(or more) bones, together with the tissues
that surround it. Joints fall into three
classes that differ in the degree of free-
dom of movement they allow: (1) immov-
able joints, e.g. the *sutures between the
bones that form the cranium; (2) slightly
movable joints, e.g. the *symphyses be-
tween the vertebrae of the spinal column;
and (3) freely movable or synovial joints,
e.g. those that occur between the limb
bones. Synovial joints include the ball-
and-socket joints (between the limbs and
the hip and shoulder girdles), which allow
movement in all directions; and the hinge
joints (e.g. at the knee and elbow), which
allow movement in one plane only. A
synovial joint is bound by ligaments and
lined with *synovial membrane.
