In chemical terms, calcium is reactive and soft for a metal ( though harder than lead, it can be cut with a knife with difficulty ).

Other soldiers stencilled identification on their knapsacks or scratched it in the soft lead backing of the Army belt buckle.

His soft lead drawings are particularly distinctive.

Since the jacket provides the strength, soft lead can be used, which allows bullets to be swaged or cast into shape before plating.

Like the element mercury, another heavy metal, lead is a neurotoxin that accumulates both in soft tissues and the bones.

The use of lead for water pipes is problematic in areas with soft or ( and ) acidic water.

Hard water forms insoluble layers in the pipes while soft and acidic water dissolves the lead pipes.

The increased velocity meant that new problems arrived, and so bullets went from being soft lead to harder lead, then to copper jacketed, in order to better engage the spiraled grooves without " stripping " them in the same way that a screw or bolt thread would be stripped if subjected to extreme forces.

Tin / lead solders, also called soft solders, are commercially available with tin concentrations between 5 % and 70 % by weight.

In 1990 the original Grammy design was revamped, changing the traditional soft lead for a stronger alloy less prone to damage, and making the trophy bigger and grander.

In conventional fishing, smallmouth may be successfully caught on a wide range of natural and artificial baits or lures, including crankbaits, hair jigs, plastic jerkbaits ( such as Rapala Husky Jerks, Mister Twister Twister Tails, Rapala X-Raps, or even a Rico Popper ), spinnerbaits, and all types of soft plastic lures, including curly tail grubs or tubes with lead head jigs.

The soft lead Minié ball was first introduced in 1847 by Claude-Étienne Minié, a captain in the French Army.

A full metal jacket ( or FMJ ) is a bullet consisting of a soft core ( usually made of lead ) encased in a shell of harder metal, such as gilding metal, cupronickel or less commonly a steel alloy.

When a hollow-point hunting bullet strikes a soft target, the pressure created in the pit forces the material ( usually lead ) around the inside edge to expand outwards, increasing the axial diameter of the projectile as it passes through.

Solid lead bullets, when cast from a soft alloy, will often deform and provide some expansion if they hit the target at a high velocity.

In addition to providing increased velocities, the hollow also turned out to provide significant expansion, especially when the bullets were cast in a soft lead alloy.

The lead coating is, however, too soft with the higher velocities of modern B. L.

* 9. 3 × 62mm: Very common big game hunting round in Scandinavia along with the 6. 5 × 55mm, where it is used as a very versatile hunting round on anything from small and medium game with lightweight cast lead bullets to the largest European big game with heavy soft point hunting bullets.

When Mantle came to bat in the eighth inning with McLain and the Tigers holding a 6-1 lead, McLain intentionally threw a soft pitch directly over home plate.

However, his facile grace also lead to accusations that he was a " lazy " batsman who was vulnerable to soft dismissals.

Although the knowledge of casting soft metals in moulds was well established before Johannes Gutenberg's time, his discovery of an alloy that was hard, durable, and would take a clear impression from the mould ( because it did not shrink as much as lead alone when cooled ) represents a fundamental aspect of his solution to the problem of printing with movable type.

It is, however, very soft and castings with pure lead are not sharp enough for printing.

The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face.

The nose wheel dug a large semi-circular furrow in the soft ground as the pilot attempted the required 180 ° turn, fortunately the rear wheels remained on the tarmac.

The aircraft ended up in the soft ground west of the end of runway, causing the failure of the nose gear.

During a sneeze, the soft palate and uvula depress while the back of the tongue elevates to partially close the passage to the mouth so that air ejected from the lungs may be expelled through the nose.

Within the British Indian Army, the Dum Dum arsenal produced its now infamous solution — the jacketing was removed from the nose of the bullet, creating the first soft point bullets.

In the surgeries — closed rhinoplasty and open rhinoplasty — an otolaryngologist ( ear, nose, and throat specialist ), a maxillofacial surgeon ( jaw, face, and neck specialist ), or a plastic surgeon, creates a functional, aesthetic, and facially proportionate nose by separating the nasal skin and the soft tissues from the osseo-cartilaginous nasal framework, correcting them as required for form and function, suturing the incisions, and applying either a package or a stent, or both, to immobilize the corrected nose to ensure the proper healing of the surgical incision.

This normal, human embryologic development is exceptionally important — because the newborn infant breathes through his or her nose during the first 6 weeks of life — thus, when a child is afflicted with bilateral choanal atresia, the blockage of the posterior nasal passage, either by abnormal bony tissue or by abnormal soft tissue, emergency remedial action is required to ensure that the child can breathe.

For plastic surgical correction, the structural anatomy of the nose comprehends: A. the nasal soft tissues ; B. the aesthetic subunits and segments ; C. the blood supply arteries and veins ; D. the nasal lymphatic system ; E. the facial and nasal nerves ; F. the nasal bones ; and G. the nasal cartilages.

The form of the nasal subunits — the dorsum, the sidewalls, the lobule, the soft triangles, the alae, and the columella — are configured differently, according to the race and the ethnic group of the patient, thus the nasal physiognomies denominated as: African, platyrrhine ( flat, wide nose ); Asiatic, subplatyrrhine ( low, wide nose ); Caucasian, leptorrhine ( narrow nose ); and Hispanic, paraleptorrhine ( narrow-sided nose ).

The surgical management of nasal defects and deformities divides the nose into six ( 6 ) anatomic subunits: ( i ) the dorsum, ( ii ) the sidewalls ( paired ), ( iii ) the hemilobules ( paired ), ( iv ) the soft triangles ( paired ), ( v ) the alae ( paired ), and ( vi ) the columella.

The external and internal nasal examination concentrates upon the anatomic thirds of the nose — upper section, middle section, lower section — specifically noting their structures ; the measures of the nasal angles ( at which the external nose projects from the face ); and the physical characteristics of the naso-facial bony and soft tissues.

Generally, the plastic surgeon first separates the nasal skin and the soft tissues from the osseo-cartilagenous nasal framework, and then corrects ( reshapes ) them as required, afterwards, sutures the incisions, and then applies either an external or an internal stent, and tape, to immobilize the newly reconstructed nose, and so facilitate the healing of the surgical cuts.

Hence, these anatomic characteristics permit dividing the nose into nasal subunits: ( i ) the midline ( ii ) the nose-tip, ( iii ) the dorsum, ( iv ) the soft triangles, ( v ) the alar lobules, and ( vi ) the lateral walls.

About ten percent of people then go on to develop tertiary disease within five to ten years ( during which further secondary lesions may come and go ), characterised by widespread bone, joint and soft tissue destruction, which may include extensive destruction of the bone and cartilage of the nose ( rhinopharyngitis mutilans or ' gangosa ').

CPAP requires the nighttime use of a machine that delivers a continuous positive pressure to the airways and preventing the collapse of soft tissues in the throat during breathing ; it is administered through a mask on either the mouth and nose together, or if that is not tolerated on the nose only ( nasal CPAP ).

Initiated by a crush switch in its nose the HEDP rocket is able to distinguish between hard and soft targets resulting in greater penetration into soft targets for increased damage potential.

The ground was covered with soft pine needles and the slope was gentle.

There was the suggestion of ice water, and -- in spite of the protest `` We're not really thirsty '' -- Linda Kay, to escape the stuffy air and the smothering soft voices, hurried to the kitchen.

The light was filtered by the soft glass window of the thermostat thus ensuring that only light absorbed by the chlorine and not by the carbon tetrachloride could enter the reaction cell.

The bone of the vertebral bodies, ribs, and sternum was soft and was easily compressed.

( 1 ) When an object was placed in the patient's hand, he had no difficulty determining whether it was warm or cold, sharp or blunt, rough or smooth, flexible, soft, or hard ; ;

The soft snow was deceitful underfoot.

She didn't mind working hard, not as if she figured to do anything wrong to live easy and soft -- all she wanted was a chance, where she wasn't marked as what she was.

She was ' hiding ' on the floor of the back seat, the soft curves of her back and hips -- rousing lines.

The only performance which was too soft for me was that of Yvette Mimieux, but since someone had to become the victim of despoilers, just to emphasize that such things do happen at these fracases, I suppose this was the attitude the part called for.

And although there was plenty of vigor in the performance, the ensemble was at its best when the playing was soft and lyrical, yet full of the suppressed tension that is one of the hallmarks of Beethoven.

Her mouth, soft and full, was something for any man to dream about.

The night we first met, at one of Mrs. Monmouth's giant parties, he was wearing a brown cashmere jacket with silver buttons and a soft pink Viyella shirt ; ;

He had fallen into a soft job, and now the job was gone and he was stranded.

This fissure extended some thirty five meters to a bed of soft marl in which a well was dug.

The soft sandstone of the walls was originally protected by plaster internally and render externally.

Caustic potash was traditionally used in conjunction with animal fats to produce soft soaps, one of the caustic processes that rendered soaps from fats in the process of saponification, known since antiquity.
