Deborah number

The Deborah number is a dimensionless number used in rheology to characterize the fluidity of materials under specific flow conditions. It quantifies the observation that given enough time a solid-like material might flow, or a fluid-like material can act solid when it is deformed enough. Materials that have low relaxation times flow and as such show rapid stress decay; the Deborah number is the ratio of fundamentally different characteristic times. Formally, the Deborah number is defined as the ratio of the time it takes for a material to adjust to applied stresses or deformations, the characteristic time scale of an experiment probing the response of the material: D e = t c t p, where tc stands for the relaxation time and tp for the "time of observation" taken to be the time scale of the process; the numerator, relaxation time, is the time needed for a reference amount of deformation to occur under a applied reference load. The denominator, material time, is the amount of time required to reach a given reference strain.

Equivalently, the relaxation time is the time required for the stress induced, by a applied reference strain, to reduce by a certain reference amount. The relaxation time is based on the rate of relaxation that exists at the moment of the applied load; this incorporates both the viscosity of the material. At lower Deborah numbers, the material behaves in a more fluidlike manner, with an associated Newtonian viscous flow. At higher Deborah numbers, the material behavior enters the non-Newtonian regime dominated by elasticity and demonstrating solidlike behavior. For example, for a Hookean elastic solid, the relaxation time tc will be infinite and it will vanish for a Newtonian viscous fluid. For liquid water, tc is 10−12 s, for lubricating oils passing through gear teeth at high pressure it is of the order of 10−6 s and for polymers undergoing plastics processing, the relaxation time will be of the order of a few seconds. Therefore, depending on the situation, these liquids may exhibit elastic properties, departing from purely viscous behavior.

While De is similar to the Weissenberg number and is confused with it in technical literature, they have different physical interpretations. The Weissenberg number indicates the degree of anisotropy or orientation generated by the deformation, is appropriate to describe flows with a constant stretch history, such as simple shear. In contrast, the Deborah number should be used to describe flows with a non-constant stretch history, physically represents the rate at which elastic energy is stored or released; the Deborah number was proposed by Markus Reiner, a professor at Technion in Israel, who chose the name inspired by a verse in the Bible, stating "The mountains flowed before the Lord" in a song by the prophet Deborah in the Book of Judges. The Deborah number is useful in conceptualizing the time–temperature superposition principle. Time-temperature superposition has to do with altering experimental time scales using reference temperatures to extrapolate temperature-dependent mechanical properties of polymers.

A material at low temperature with a long experimental or relaxation time behaves like the same material at high temperature and short experimental or relaxation time if the Deborah number remains the same. This can be useful when working with materials which relax on a long time scale under a certain temperature; the practical application of this idea arises in the Williams–Landel–Ferry equation. Time-temperature superposition avoids the inefficiency of measuring a polymer's behavior over long periods of time at a specified temperature by utilizing the Deborah number. J. S. Vrentas, C. M.

First Kiss (Kid Rock album)

First Kiss is the tenth studio album by American singer and songwriter Kid Rock. The album was released on February 24, 2015, through Warner Bros. Records and Top Dog Records, is his first and only with Warner Bros. after leaving sister label Atlantic Records in 2014. First Kiss received mixed reviews from music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from critics, the album received an average score of 61, which indicates "generally favorable reviews", based on 9 reviews. Stephen Thomas Erlewine of AllMusic said, "It's a bit bumpy and sometimes sleepy but it finds old Bob Ritchie settling into his comfort zone, knowing that he's in it for the long haul." Anthony DeCurtis of Rolling Stone said, "First Kiss presents few surprises because Kid Rock's journey from abrasive rap metal to unreconstructed heartland rock has landed him in a sweet spot: big guitars, big drums, big choruses and gravelly vocals." Richard Bienstock of Billboard said, "First Kiss is hardly his most adventurous project, but it is his most easygoing, tuneful one.

The production is crisp and clean, the guitars are sparkling, the vibe is rollicking but relaxed. He sounds better here than he has in a long time." The album debuted at number two on the Billboard 200, with sales of 137,000 copies in the United States. As of December 2015, First Kiss has sold more than 354,000 copies in the United States; the album debuted at number two in Canada on the Canadian Albums Chart, with sales of 8,000. All songs were produced by Kid Rock, except "First Kiss" and "Drinking Beer With Dad" were produced by Kid Rock and Dan Huff.

Atlantis (DC Comics)

The fictional island of Atlantis appears in pop-culture in comic books. The most notable example is related to Namor of Marvel Comics and a particular version of Aquaman in DC Comics. Atlantis is a fictional location appearing in American comic books published by Marvel Comics, it is based on the mythical island of Atlantis first mentioned in Plato's initial dialogue the Timaeus, written c. 360 BC. In the Marvel Universe, Atlantis was a small continent with many human settlements. Over 21,000 years ago, an event called; the inhabitants of ancient Atlantis built an enormous glass-like dome over the capital city known as Atlantis. When barbarians sent by the Deviant Lemuria empire attacked Atlantis, King Kamuu opened the magma-pits which were the city's means of heating; this caused the continent to sink. Kamuu was warned of the Great Cataclysm by Zhered-Na; when she refused to recant, he had her exiled to the mainland, where she was stabbed to death by survivors of the submersion. The priests and intellectuals of the city Netheria foresaw the Lemurian attack and fortified their city, thus it sank intact.

Netheria still exists today, ruled by Queen Kala. Other ancient Atlanteans survived the sinking of the continent by various methods, including Dakimh the Enchanter and Stygyro. About 8,000 years ago, a group of Homo mermanus nomads discovered the ruins of the city of Atlantis, they made the ruins of the human settlements in Atlantis their home and went on to develop a society there using as much of the material as they could salvage from the wreckage. These people are thus referred to as "Atlanteans", as it is in the city of Atlantis that their first complex society emerged. Five hundred years after the settlement of Atlantis, another group of Homo mermanus leave Atlantis to find their own city; these "Lemurians", as they now call themselves, discover the Serpent Crown in the ruins of their city. The Serpent Crown had been crafted by ancient Atlantean alchemists as a vessel empowered by the demonic Elder God Set. Through their leader Naga's exposure and extensive use of the ancient mystical device, they become more serpent-like in appearance than their Atlantean cousins.

Atlanteans have little or no contact with their human cousins for millennia. However, the two races come into sustained contact hostile, beginning in the 20th century. On occasions, Atlanteans invade the surface world; the current Prince, Namor the Sub-Mariner, is hostile to the surface world, but fights in alliance with the Allied Powers against the Axis Powers during World War II. Namor defends Atlantis against villains like Attuma and Warlord Krang, who plot to overthrow him and take over Atlantis; the city of Atlantis is damaged when the super-villain Nitro explodes, taking with him Namor's traitorous son, Kamar. Following Namor's attack on Wakanda during Avengers vs. X-Men, the two nations engage in a violent conflict. After much bloodshed, Namor reaches out to Black Panther and extends a peace offering to Queen Shuri. Despite this, Wakanda launches an all out strike on Atlantis, destroying the city and killing a number of Namor's soldiers in the process. In Tales of Suspense #43, Iron Man meets a separate tribe of Atlanteans whose city sank to the bottom of the sea and has been renamed the Netherworld.

He soon discovers that their Queen, Kala, is planning to invade the surface with advanced technology. Iron Man stops her by bringing her to the surface, where it is revealed that Netherworlders age when above ground. Though she is restored to her desired age when she returns to the Netherworld, Kala’s hopes of ruling the surface world are diminished, though she attempts to do so several more times, all without success. In a “Tuk the Caveboy” story sequence from Captain America #2 & 3, Tuk and Tanir meet Eve, princess of the not-yet lost kingdom of Atlantis, whom they aid in reclaiming the throne from her wicked uncle; the Exiles visited other realities. On Earth-1016, the Exiles came across a reality where the forces of Atlantis were exterminating mankind, they teamed up with that reality's Doctor Doom to fend off the Atlanteans. Counter-Earth has its version of Atlantis. Proteus trapped the Atleanteans inside as a way to suffocate them. In the Marvel Noir reality, Atlantis matched the descriptions of Plato with it being near the Pillars of Heracles, being highly-advanced, powered by the Orichalcum.

As the Orichalcum proved to be too powerful to be the Atlantean's superconductor, it created a vortex that sunk Atlantis beneath the ocean. The ruins of the Ultimate Marvel version of Atlantis are discovered by the Fantastic Four during an expedition. Unlike its Earth-616 counterpart, this version of Atlantis is shown to have been devoid of any life for thousands of years. Upon being found by the Four, Namor suggests that the continent had been destroyed by Lemuria at some point during his time in stasis. During the Ultimatum storyline, it is revealed that the ruins of Atlantis do contain a small pocket of survivors led by Namora. One of the earliest mentions of Atlantis occurs in Action Comics #17, in a "Zatara the Magician" story; the city was visually depicted in the following month's "Zatara" story in Action Comics #18. The city appeared in several DC comics of the 1940s and 1950s: In Batman #19, Atlantis is shown to be inhabited by an advanced people ruled by an Emperor; the Nazis are using it as a Naval Base.

Batman and Robin discover the base and are able to reveal the deception of t
