Hardness
In materials science, hardness (antonym: softness) is a measure of the resistance to plastic deformation, such as an indentation (over an area) or a scratch (linear), induced mechanically either by Pressing (metalworking), pressing or abrasion (mechanical), abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and common plastics. Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, hardness can be measured in different ways, such as scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elasticity (physics), elastic stiffness, plasticity (physics), plasticity, deformation (mechanics), strain, strength of materials, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Hardtack
Hardtack (or hard tack) is a type of dense Cracker (food), cracker made from flour, water, and sometimes salt. Hardtack is inexpensive and long-lasting. It is used for sustenance in the absence of perishable foods, commonly during long sea voyages, land migrations, and military campaigns. Along with salt pork and corned beef, hardtack was a Field ration, standard ration for many militaries and navies from the 17th to the early 20th centuries. Etymology The name is derived from "tack", the British sailor slang for food. The earliest use of the term recorded by the ''Oxford English Dictionary'' is from 1830. It is known by other names including ''brewis'' (possibly a cognate with "brose"), ''cabin bread'', ''pilot bread'', ''sea biscuit'', ''soda crackers'', ''sea bread'' (as rations for sailors), ''ship's biscuit'', and pejoratively as ''Dog biscuit, dog biscuits'', ''Molar (tooth), molar breakers'', ''sheet iron'', ''tooth dullers'', ''Panzerplatten'' ("''armor plates''"; Germany ...

Hardcourt
A hardcourt (or hard court) is a type of surface or floor on which a sport is played, most usually in reference to tennis courts. It is typically made of rigid materials such as asphalt or concrete, and covered with acrylic resins to seal the surface and mark the playing lines, while providing some cushioning. Historically, hardwood surfaces were also in use in indoor settings, similar to an indoor basketball court, but these surfaces are rare now. Tennis Tennis hard courts are made of synthetic/acrylic layers on top of a concrete or asphalt foundation and can vary in color. These courts tend to play medium-fast to fast because there is little energy absorption by the court, as with grass courts but unlike clay courts. The ball tends to bounce high and players are able to apply many types of spin during play. Speed of rebound after tennis balls bounce on hard courts is determined by how much sand is in the synthetic/acrylic layer placed on top of the asphalt foundation. More sa ...

Palatalization (phonetics)
In phonetics, palatalization (, ) or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate. Consonants pronounced this way are said to be palatalized and are transcribed in the International Phonetic Alphabet by affixing a superscript ''j'' ⟨ʲ⟩ to the base consonant. Palatalization is not Phonemic contrast, phonemic in English, but it is in Slavic languages such as Russian language, Russian and Ukrainian language, Ukrainian, Finnic languages such as Estonian language, Estonian, Karelian language, Karelian, and Võro language, Võro, and other languages such as Irish language, Irish, Marshallese language, Marshallese, Kashmiri language, Kashmiri, and Japanese language, Japanese. Types In technical terms, palatalization refers to the secondary articulation of consonants by which the body of the tongue is raised toward the hard palate and the alveolar ridge during the articulation of the consonant. Such consonants are phon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Erection
An erection (clinically: penile erection or penile tumescence) is a Physiology, physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous. The shape, angle, and direction of an erection vary considerably between humans. Physiologically, an erection is required for a male to effect penetration or sexual intercourse and is triggered by the parasympathetic division of the autonomic nervous system, causing the levels of nitric oxide (a vasodilation, vasodilator) to rise in the Trabeculae of corpora cavernosa of penis, trabecular artery, arteries and smooth muscle of the penis. The arteries Vasodilation, dilate causing the Corpus cavernosum penis, corpora cavernosa of the penis (and to a lesser extent the corpus spongiosum) to fill ...
