Higher-quality stainless steel pressure cookers are made with heavy, three-layer, or copper-clad bottoms ( heat spreader ) for uniform heating because stainless steel has lower thermal conductivity.

Higher-quality phones can transfer this signal to the handset with less interference over a greater range, however.

Higher-quality paper, such as that used in commercial magazines, has less dot gain, and can range up to 300 LPI with quality glossy ( coated ) paper.

Higher-quality catalyst, added at a slower rate and at reduced temperature, was shown to produce high molecular weight PATs with no insoluble polymer residue.

Higher-quality LVT film recorders use a focused beam of light to write the image directly onto a film loaded spinning drum, one pixel at a time.

Higher-quality Dornfelder wines are velvety textured, slightly floral, often show flavours of plums, blackberries or cherries, and are typically oaked.

Higher-quality video such as video in high definition ( 720p +) requires higher bandwidth and faster connection speeds.

Well known armour types in European history include the lorica hamata, lorica squamata, and the lorica segmentata of the Roman legions, the mail hauberk of the early medieval age, and the full steel plate harness worn by later medieval and renaissance knights, and breast and back plates worn by heavy cavalry in several European countries until the first year of World War I ( 1914 – 15 ).

Iron armour could be carburised or case hardened to give a surface of harder steel.

Soldiers in the American Civil War bought iron and steel vests from peddlers ( both sides had considered but rejected body armour for standard issue ).

A trend toward composite armour is taking place in place of steel-composites are stronger for a given weight, allowing the tank to be lighter for the same protection as steel armour, or better protected for the same weight.

Mail armour provided an effective defence against slashing blows by an edged weapon and penetration by thrusting and piercing weapons ; in fact a study conducted at the Royal Armouries at Leeds concluded that " it is almost impossible to penetrate using any conventional medieval weapon " Generally speaking, mail's resistance to weapons is determined by four factors: linkage type ( riveted, butted, or welded ), material used ( iron versus bronze or steel ), weave density ( a tighter weave needs a thinner weapon to surpass ), and ring thickness ( generally ranging from 18 to 14 gauge in most examples ).

Often this protection is provided by armour plates and steel jackets.

the plates of lorica segmentata armour were soft iron inside and ( some at least ) were mild steel on the outside.

In a modern test, a direct hit from a steel bodkin point penetrated Damascus mail armour.

However, even heavy-draw longbows have trouble penetrating well-made steel plate armour, which was used increasingly after 1350.

Modern tanks possess very thick composite armour consisting of layers of steel, ceramics, plastics and Kevlar, and these materials have melting points well above the burning temperature of gasoline, which makes the vehicles themselves invulnerable to Molotov cocktails.

In a modern test, a direct hit from a hard steel bodkin point penetrated Damascus chain armour.

However, there is no sound evidence that Edward ever wore black armour, although Harvey ( without citing a source ) refers to " some rather shadowy evidence that he was described in French as clad at the battle of Crecy " en armure noire en fer bruni "-in black armour of burnished steel ".

On screen it is almost impossible to distinguish between the polyurethane stunt armour and steel armour, much of which was also made by Armordillo.

Heath Ledger's armour was originally made in steel along with 3 x Polyurethane stunt replicas.

The stopping power of glass exceeds that of armour steel on a thickness basis and in many cases glass is more than twice as good as steel on a thickness basis.

It used an armour known as Combination K, which apparently is glass-reinforced plastic sandwiched between inner and outer steel layers.

Chobham sandwiches a layer of ceramic between two plates of steel armour, which was shown to dramatically increase the resistance to HEAT rounds, even in comparison to other composite armour designs.

The armour, at some places a foot thick, consisted of a layer of concrete sandwiched between layers of steel, successfully rendering the vehicle impervious against small arms fire and small explosives.

While slashing attacks were still moderately effective against infantry wearing half-plate armor, cutting and slicing attacks against an opponent wearing plate armour were almost entirely ineffective in providing any sort of slashing wound as the sword simply could not cut through the steel, although a combatant could aim for the chinks in a suit of armour, sometimes to great effect.

Also, modern militaries usually do not equip their forces with the best armour available, since it would be prohibitively expensive.

: The barbarians thought that Romans would not be able to cross it without a bridge, and consequently bivouacked in rather careless fashion on the opposite bank ; but he sent across a detachment of Germanic tribesmen, who were accustomed to swim easily in full armour across the most turbulent streams.

If it was instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed.

It is doubtful that the Athenians ran the whole distance ; in full armour this would be very difficult.

An example of this would be kusari gusoku which means chain armour.

In addition, new technologies and tactics were developed, making most defences obsolete ; this led to the construction of star forts, specifically designed to withstand artillery bombardment though these too ( along with the Martello Tower ) would find themselves rendered obsolete when explosive and armour piercing rounds made even these types of fortifications vulnerable.

Once in the arena morgue, the corpse would have been stripped of armour, and probably had its throat cut to prove that dead was dead.

A more well-to-do hoplite would have linothorax, armour composed of stitched / laminated linen fabrics that was sometimes reinforced with animal skins and / or bronze scales.

Such a small weapon would be particularly useful after many hoplites had started to abandon body armour during the Peloponnesian War.

When worn with full armour, the tachi would be accompanied by a shorter blade in the form known as koshigatana (" waist sword "); a type of short sword with no hand-guard ( tsuba ) and where the hilt and scabbard meet to form the style of mounting called an aikuchi (" meeting mouth ").

A principle was introduced that the thickness of side armour on a ship would equal the calibre of the large guns, while ships were increasingly divided internally into watertight compartments to make them more resistant to flooding when damaged.

(" Jack coat " armour could be up to twice as thick as the coat tested ; in Bane's opinion such a thick coat would have stopped bodkin arrows but not the cutting force of broadhead arrows.

In Bane's view, the plate armour would have kept out all the arrows if thicker or worn with more padding.

Strickland and Hardy suggest that " even at a range of 240 yards heavy war arrows shot from bows of poundages in the mid-to upper range possessed by the Mary Rose bows would have been capable of killing or severely wounding men equipped with armour of wrought iron.

Modern tests and contemporary accounts agree therefore that well-made plate armour could protect against longbows, however there are a number of caveats to this point ; not all plate armour was well-made or well looked after, and there were also weak points in the eye and air holes and joints where arrows could penetrate, meaning that even if the armour was proof against nearly all arrows, being shot at by thousands of longbowmen would have been an uncomfortable experience, physically and mentally.

Even peasants, who did not share the bonds of kinship and culture, would often avoid killing a nobleman, valuing the high ransom that a live capture could bring, as well as the valuable horse, armour and equipment that came with him.

It was a tight battle ; Philip was unhorsed by the Flemish pikemen in the heat of battle, and were it not for his plate mail armour in which he was encased, he would probably have been killed.

Ancient authors seemed to believe, incorrectly, that sling-bullets could penetrate armour, and that lead projectiles, heated by their passage through the air, would melt in flight.

More frequently, he played parts that no one else wanted to play ( generally because they required a lot of make-up or uncomfortable costumes, such as a recurring knight in armour who would end sketches by walking on and hitting one of the other characters over the head with a plucked chicken ) and took a number of small roles in the films, including Patsy in Monty Python and the Holy Grail ( which he co-directed with Terry Jones, where Gilliam was responsible for photography, while Jones would guide the actors ' performances ) and the jailer in Monty Python's Life of Brian.

Additionally, several thousand Germanic soldiers were deserting militiamen who wore Roman armour ( which would thus show up as " Roman " in the archaeological digs ), and in fact the Germanic tribes wore less metal and more perishable organic material.

It was thought that XXX Corps would face limited resistance on their route up Highway 69 and little armour.
