Articles from Oak Ridge National Laboratory ( ORNL ) indicate that the term stands for " safety cut rope axe man ", referring in that case to the early neutronic safety mechanism of using a person equipped with an axe to cut the rope suspending the control rods over the Chicago Pile nuclear reactor, at which point the rods would fall by gravity into the reactor core, shutting the reactor down.

The MSRE was a 7. 4 MW < sub > th </ sub > test reactor simulating the neutronic " kernel " of a type of inherently safe epithermal thorium molten salt breeder reactor called the Liquid fluoride thorium reactor.

Western light water reactors are not subject to very large uncontrolled power excursions because loss of coolant decreases, rather than increases, core reactivity ( a negative void coefficient of reactivity ); " transients ," as the minor power fluctuations within Western light water reactors are called, are limited to momentary increases in reactivity that will rapidly decrease with time ( approximately 200 %-250 % of maximum neutronic power for a few seconds in the event of a complete rapid shutdown failure combined with a transient ).

transients in which the neutronic response of the core is important.

After completing his studies in electronics, he was hired by the Defense Nationale in 1978 to work on the final tests of the neutronic head, the detonator for the French atomic bomb.

The arithmetic mean has several properties that make it useful, especially as a measure of central tendency.

Bronze, an alloy of copper and tin, was the first alloy discovered, during the prehistoric period now known as the bronze age ; it was harder than pure copper and originally used to make tools and weapons, but was later superseded by metals and alloys with better properties.

Other significant properties are high specific heat ( 1925 J · kg < sup >− 1 </ sup >· K < sup >− 1 </ sup >) and thermal conductivity ( 216 W · m < sup >− 1 </ sup >· K < sup >− 1 </ sup >), which make beryllium the metal with the best heat dissipation characteristics per unit weight.

Moreover, because the properties were security for his unpaid debt to the Queen in the Court of Wards, he had had to enter into a bond with the purchaser, guaranteeing that he would indemnify them if the Queen were to make a claim against the lands to collect on the debt.

Lactic acid bacteria have antagonistic properties which make them particularly useful as biopreservatives.

Similarly, critics of externalist foundationalism argue that only mental states or properties the believer is aware of could make a belief justified.

Soon Jean-Pierre Serre noticed that some properties of étale coverings mimicked those of open immersions, and that consequently it was possible to make constructions which imitated the cohomology functor H < sup > 1 </ sup >.

# Pretreatments to make the raw materials ready for the main extraction step and to remove impurities which may have negative effects on physio chemical properties of the final gelatin product,

Whale chose Frankenstein, mostly because none of Universal's other properties particularly interested him and he wanted to make something other than a war picture.

One theme in research literature is to identify what the " hard " instances of the knapsack problem look like, or viewed another way, to identify what properties of instances in practice might make them more amenable than their worst-case NP-complete behaviour suggests.

There is a large variety of knots, each with properties that make it suitable for a range of tasks.

These two properties make the calculations tractable.

These properties make salient the sometimes parasitic nature of acquired memes, and as a result individuals should be motivated to reflectively acquire memes using what he calls a " Neurathian bootstrap " process.

The properties that make this relation a congruence relation ( respecting addition, subtraction, and multiplication ) are the following.

In the cosmetics industry, its reflective and refractive properties make mica an important ingredient in blushes, eye liner, eye shadow, foundation, hair and body glitter, lipstick, lip gloss, mascara, moisturizing lotions, and nail polish.

The noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.

In classical physics this does not make sense, since any number of properties can be measured simultaneously with arbitrary accuracy.

Actinium has similar chemical properties as lanthanum and other lanthanides, and therefore these elements are difficult to separate when extracting from uranium ores.

Because the size of the dispersed phase may be difficult to measure, and because colloids have the appearance of solutions, colloids are sometimes identified and characterized by their physico-chemical and transport properties.

This monocolored design promotes the fabrication of micrometer-or nanometer-scaled light mills, for it is difficult to pattern materials of distinct optical properties within a very narrow, three-dimensional space.

It is a difficult task to give novelty to what is old, authority to what is new, brilliance to the common-place, light to the obscure, attraction to the stale, credibility to the doubtful, but nature to all things and all her properties to nature.

The isotope of einsteinium with the longest half life, einsteinium-252 ( half life 471. 7 days ) would be more suitable for investigation of physical properties, but it has proven far more difficult to produce and is available only in minute quantities, and not in bulk.

The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity.

The chemical properties of hafnium and zirconium are nearly identical, which makes the two difficult to separate.

To kludge around something is to avoid a bug or some difficult condition by building a kludge, perhaps relying on properties of the bug itself to assure proper operation.

Since lyotropic liquid crystals rely on a subtle balance of intermolecular interactions, it is more difficult to analyze their structures and properties than those of thermotropic liquid crystals.

Niobium has physical and chemical properties similar to those of the element tantalum, and the two are therefore difficult to distinguish.

A pyrimidine has many properties in common with pyridine, as the number of nitrogen atoms in the ring increases the ring pi electrons become less energetic and electrophilic aromatic substitution gets more difficult while nucleophilic aromatic substitution gets easier.

Achieving high vacuum is difficult because all of the materials exposed to the vacuum must be carefully evaluated for their outgassing and vapor pressure properties.

Unfortunately, both properties are difficult to measure objectively, and only perceptual evaluations can be performed.

Lucretius compares his work in this poem to that of a doctor healing a child: just as the doctor may put honey on the rim of a cup containing bitter wormwood ( most likely Absinth Wormwood ) believed to have healing properties, the patient is " tricked " into accepting something beneficial but difficult to swallow, " but not deceived " by the doctor.

Isotope separation is difficult because two isotopes of the same elements have very nearly identical chemical properties, and can only be separated gradually using small mass differences.

Determining what average input means is difficult, and often that average input has properties which make it difficult to characterise mathematically ( consider, for instance, algorithms that are designed to operate on strings of text ).

The disputes erupted again in 1282 ; this time, the conflict was for the lands and properties seized by the church in a difficult period that followed after the Battle of Legnica, and for the violation of the immunity of the Church hierarchy in trials.
