A mechanical device test stand is one specific type of test stand.
 It is a facility used to develop, characterize and test mechanical components.
 The facility allows for the testing of the component and, it offers measurement of several physical variables associated to the functionality of the component.
 Such components could be electromechanical, motors or tools.
 The intended use of the test stand is for compliance testing of predetermined desired values and fatigue testing.
London (the capital city of England and the United Kingdom) has a history going back over 2,000 years.
 In that time, it has grown to one of the most significant financial and cultural capitals on Earth.
 It has withstood plague, devastating fire, civil war, aerial bombardment, terrorist attacks, and widespread rioting.
 The City of London is its historic core and today is its primary financial district, though it now represents a tiny part of the wider metropolis of Greater London.
Prevotella nigrescens has a gram negative gram stain.
 When P. nigrescens microflora colonize they trigger an over-aggressive response from the immune system and increase the incidence of many diseases and infections.
 One specific type of bacteria that is part of the normal oral flora but leads to disease when it infects the local tissue.
 This bacteria has no means of motility and has a Bacilli (rod) shape.
 "Prevotella" species are part of the human oral and vaginal flora.
 They play a role in the pathogenesis of periodontal disease, gingivitis, and extraoral infections such as nasopharyngeal and intra-abdominal infections also some odontogenic infections, and strains are usually carried in families, in so-called intrafamilial carriage.
 It is also associated with carothid atherosclerosis.
Storm Stories is a non-fiction television series that aired on The Weather Channel (TWC) and Zone Reality.
 It is hosted and narrated by meteorologist and storm tracker Jim Cantore.
 "Storm Stories" showcases various types of severe weather, such as tornadoes, hurricanes, and blizzards.
 Each episode features a famous severe storm, and survivors of it sharing their experiences.
 The program also features footage of the storm if it is available, but typically a re-enactment is used instead.
 The video of the storm is often shown while the survivors offer their accounts of it.
 Often, TWC would air a special week dedicated to one specific type of storm.
Pentane interference or "syn"-pentane interaction is the steric hindrance that the two terminal methyl groups experience in one of the chemical conformations of n-pentane.
 The possible conformations are combinations of anti conformations and gauche conformations and are anti-anti, anti-gauche, gauche - gauche and gauche - gauche of which the last one is especially energetically unfavorable.
 In macromolecules such as polyethylene pentane interference occurs between every fifth carbon atom.
 This is not to be confused with the 1,3-diaxial interactions of cyclohexane derivatives (gauche interactions shared between substituents and the ring).
 A clear example of the "syn"-pentane interaction is apparent in the diaxial versus diequatorial heats of formation of "cis" 1,3-dialkyl cyclohexanes.
 Relative to the diequatorial conformer, the diaxial conformer is 2-3 kcal/mol higher in energy than the value that would be expected based on 1,3-diaxial interactions alone.
 Pentane interference helps explain molecular geometries in many chemical compounds, product ratios, and purported transition states.
 One specific type of "syn"-pentane interaction is known as "1,3 allylic strain" or (A strain).
2-Bromo-LSD, also known as BOL-148, is a derivative of lysergic acid invented by Albert Hofmann, as part of the original research from which the closely related compound LSD was also derived.
 2-bromo-LSD was found to be inactive as a psychedelic and so was comparatively little researched for many years, although its similar behavior in the body made it useful for radiolabelling studies.
 It was found to bind to many of the same receptor targets as LSD, but acting as a neutral antagonist rather than an agonist.
 However its generally similar behavior to LSD in some respects has shown to be very useful in one specific area, the treatment of cluster headaches.
 These debilitating attacks have been known for some time to be amenable to treatment with certain hallucinogenic drugs such as LSD and psilocybin, but because of the illegal status of these drugs and the kind of mental changes they induce, research into their medical use has been slow and therapeutic application limited to very specific circumstances under strict supervision.
 It had been thought that this specific therapeutic action against cluster headaches was limited to hallucinogenic drugs of this type, and would always present a major barrier to their clinical use.
 However a serendipitous discovery found that 2-bromo-LSD is also able to produce this therapeutic effect, despite lacking the other effects of LSD.
 This has led to a resurgence of interest and research into 2-bromo-LSD and its possible medical uses.
 Some isolated incidents of hallucinogenic responses have been reported, but as with other non-hallucinogenic LSD analogues such as lisuride, this appears to be a rare side effect occurring only in individuals with an as yet unexplained susceptibility to this reaction.
Solid dispersion redox flow battery is one specific type of redox flow battery using dispersed solid active materials as the energy storage media.
 The solid suspensions are stored in energy storage tanks and pumped through electrochemical cells while charging or discharging.
 In comparison with a conventional redox flow battery where active species are dissolved in aqueous or organic electrolyte, the active materials in a solid dispersion redox flow battery maintain the solid form and are suspended in the electrolyte.
 The solid active materials, especially with active materials from lithium-ion battery, can help the suspensions achieve much higher energy densities than conventional redox flow batteries.
 This concept is similar to semi-solid flow batteries in which slurries of active materials accompanied by conductive carbon additives to facilitate electrons conducting are stored in energy storage tanks and pumped through the electrochemical reaction cells.
Lithic sandstones, or lithic arenites, or litharenites, are sandstones with a significant (>5%) component of lithic fragments, though quartz and feldspar are usually present as well, along with some clayey matrix.
 Lithic sandstones can have a speckled (salt and pepper) or gray color, and are usually associated with one specific type of lithic fragment (i.e., igneous, sedimentary, or metamorphic).
Targeted threats are a class of malware destined for one specific organization or industry.
 A type of crimeware, these threats are of particular concern because they are designed to capture sensitive information.
 Targeted attacks may include threats delivered via SMTP e-mail, port attacks, zero day attack vulnerability exploits or phishing messages.
 Government organisations are the most targeted sector.
 Financial industries are the second most targeted sector, most likely because cybercriminals desire to profit from the confidential, sensitive information the financial industry IT infrastructure houses.
 Similarly, online brokerage accounts have also been targeted by such attacks.
The Blitz was a German bombing offensive against Britain in 1940 and 1941, during the Second World War.
 The term was first used by the British press as an abbreviation of "Blitzkrieg" (lightning war).
 The Germans conducted mass air attacks against industrial targets, towns and cities, beginning with raids on London towards the end of the Battle of Britain in 1940, a battle for daylight air superiority between the "Luftwaffe" and the Royal Air Force over the United Kingdom.
 By September 1940, the "Luftwaffe" had failed and the German air fleets ("Luftflotten") were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.
 Adolf Hitler and "Reichsmarschall" Hermann Göring, commander-in-chief of the "Luftwaffe", ordered the new policy on 6 September 1940.
 From 7 September 1940, London was systematically bombed by the "Luftwaffe" for 56 out of the following 57 days and nights.
 Most notable was a large daylight attack against London on 15 September.

Question: Both London and German have seen attacks during war, there was one specific type of attack that Germany called the blitz, what did London call a similar attack?
Answer: aerial bombardment
