Front wheel is locked with U-lock and cables, but the rest of the bicycle is gone.

For several years, Ripon offered new freshmen the option of receiving a free Trek 820 mountain bike, helmet, and U-lock if they pledged not to bring a car to campus for the entire year.

Many cyclists use a long cable to secure bicycle components ( such as the wheels or seat ) in conjunction with a U-lock or padlock to secure the frame.

Yet often fear persists because, even with the most rigid ritual, one is never quite free from the uneasy feeling that one might make some mistake or that in every previous execution one had been unaware of the really decisive act.

As a Humanist, Dr. Huxley interests himself in the possibilities of human development, and one thing we can say about this suggestion, which comes from a leading zoologist, is that, so far as he is concerned, the scientific outlook places no rigid limitation upon the idea of future human evolution.

In urethane foams, for example, there has been a definite trend toward the polyether-type materials ( which are now available in two-component rigid foam systems ) and the emphasis is definitely on one-shot molding.

In a typical application -- the making of rigid urethane foam sandwich panels -- an amount of foam mixture calculated to expand 10 to 20% more than the volume of the panel is poured into the panel void and the top of the panel is locked in place by a jig.

However implausible this is, it is certainly the case that Aristotle's rigid separation of action from production, and his justification of the subservience of slaves and others to the virtue – or arete – of a few justified the ideal of aristocracy.

In some taxa the texture is leathery, fleshy, or even rigid, but always with stomata.

Ambrose displayed a kind of liturgical flexibility that kept in mind that liturgy was a tool to serve people in worshiping God, and ought not to become a rigid entity that is invariable from place to place.

The traditional Buddhist understanding of non-violence is not as rigid as the Jain one, but like the Jains, Buddhists have always condemned the killing of all living beings.

The angular momentum of a system of particles ( e. g. a rigid body ) is the sum of angular momenta of the individual particles.

The angular momentum of a particle or rigid body in rectilinear motion ( pure translation ) is a vector with constant magnitude and direction.

If the path of the particle or centre of mass of the rigid body passes through the given origin, its angular momentum is zero.

This second term can be even further simplified if the particles form a rigid body, in which case it is the product of moment of inertia and angular velocity of the spinning motion ( as above ).

Fay refuses to take her wig off, and confesses to him that this disguise, left over from a college play, is the only way she can break out of her rigid and cynical persona.

As Fay resumes work, Detmold's real new assistant arrives, and Fay is horrified to realize that she is even more practical, rigid and disbelieving than Fay herself, and the new nurse marches the Cookies off to the next town to disprove the new miracle.

The most common type of bus is the single-decker rigid bus, with larger loads carried by double-decker buses and articulated buses, and smaller loads carried by midibuses and minibuses ; coaches are used for longer distance services.

This is accompanied by physical problems such as speech impairment, jerky movements ( myoclonus ), balance and coordination dysfunction ( ataxia ), changes in gait, rigid posture, and seizures.

They can be divided broadly into two categories: dualist solutions that maintain Descartes ' rigid distinction between the realm of consciousness and the realm of matter but give different answers for how the two realms relate to each other ; and monist solutions that maintain that there is really only one realm of being, of which consciousness and matter are both aspects.

The view that there was no rigid structure is reinforced by S. T. Joshi, who stated " Lovecraft's imaginary cosmogony was never a static system but rather a sort of aesthetic construct that remained ever adaptable to its creator's developing personality and altering interests ... here was never a rigid system that might be posthumously appropriated ... he essence of the mythos lies not in a pantheon of imaginary deities nor in a cobwebby collection of forgotten tomes, but rather in a certain convincing cosmic attitude.

The internal energy change of a process is equal to the heat change if it is measured under conditions of constant volume, as in a closed rigid container such as a bomb calorimeter.

The Secretary of the Interior or any duly authorized representative shall be entitled to admission to, and to require reports from the operator of, any metal or nonmetallic mine which is in a State ( excluding any coal or lignite mine ), the products of which regularly enter commerce or the operations of which substantially affect commerce, for the purpose of gathering data and information necessary for the study authorized in the first section of this Act.

Another recent achievement was the successful development of a method for the complete combustion in a bomb calorimeter of a metal in fluorine when the product is relatively non-volatile.

Even here there is room for some variation, for metal surfaces vary in smoothness, absorptive capacity, and chemical reactivity.

Each teacher has in his classroom a metal file, equipped with a lock, which is used to store cumulative record folders.

Preparation of a coordination compound is often accomplished by the simple method of reacting a metal salt with a ligand in a suitable solvent such as an alcohol.

Particular interest is directed towards the condensation of these ligands with metal halides to form substituted phosphide or arside complexes.

Make sure that the metal tube through which the wire passes is in the shape of an inverted `` L '', the foot of the `` L '' about three inches long, so that the puppet can hang directly under the light.

Made of gold-plated britannium on a black metal base, it is 13. 5 in ( 34 cm ) tall, weighs 8. 5 lb ( 3. 85 kg ) and depicts a knight rendered in Art Deco style holding a crusader's sword standing on a reel of film with five spokes.

In the modern IUPAC nomenclature, the alkali metals comprise the group 1 elements, excluding hydrogen ( H ), which is nominally a group 1 element but not normally considered to be an alkali metal as it rarely exhibits behaviour comparable to that of the alkali metals.

Experiments have been conducted to attempt the synthesis of ununennium ( Uue ), which is likely to be the next member of the group, but they have all met with failure .< ref name =" link "> However, ununennium may not be an alkali metal due to relativistic effects, which are predicted to have a large influence on the chemical properties of superheavy elements.

Antimony is a silvery, lustrous gray metal that has a Mohs scale hardness of 3.

Metallic antimony is a brittle, silver-white shiny metal.

Americium is a relatively soft radioactive metal with silvery appearance.

Astatine is sometimes described as being a black solid ( assuming that it follows this trend ), or as having a metallic appearance ( if it is a metalloid or a metal ).

Steel is a metal alloy whose major component is iron, with carbon content between 0. 02 % and 2. 14 % by mass.

Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties.

The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal.

The primary metal is called the base, the matrix, or the solvent.

When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism.

With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal.

These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized.

While the use of iron started to become more widespread around 1200 BC, mainly because of interruptions in the trade routes for tin, the metal is much softer than bronze.
