The moisture content of the top layer of coniferous needles and twigs covering the forest floor is one of the factors of forest fire danger which must be determined accurately if fire danger in such timber types is to be measured.... For daily use at numerous field stations, where duff is a forest fire fuel of material significance, some instrumental method giving an immediate indication of duff moisture is necessary. To meet this need [a member] of the U. S. [United States] Forest Products Laboratory, in 1923, invented an instrument called a duff hygrometer.  2, record 3, English, - duff%20hygrometer

The preliminary mechanical processing of the dried [hemp] stalks involves some fairly vigorous handling of the raw material, including breaking, scutching and the separation of the line fibres from the tow and other by-products. The stronger, more solid fibre bundles keep their original lengths and parallelism. During breaking and scutching the weaker and shorter fibres(tow), especially those at the foot of the stalks, break away and are removed together with the hurds, dust, soil, etc.... The hurds are removed pneumatically and may be sold for use as natural fertiliser, for the heat insulation of buildings, as fuel or as animal litter...

Fluidized bed combustion systems use a heated bed of sand-like material suspended(fluidized) within a rising column of air to burn many types and classes of fuel. This technique results in a vast improvement in combustion efficiency of high moisture content fuels, and is adaptable to a variety of "waste type" fuels. The scrubbing action of the bed material on the fuel particle enhances the combustion process by stripping away the carbon dioxide and char layers that normally form around the fuel particle. This allows oxygen to reach the combustible material much more readily and increases the rate and efficiency of the combustion process.  3, record 12, English, - fluidized%20bed%20system

After the depleted fuel assemblies are removed from the reactor, they are placed in a canister … The canister alone, however, is not sufficient to provide adequate gamma or neutron radiation shielding. Therefore, apparatus that provide additional radiation shielding are required during transport, preparation and subsequent dry storage … The additional shielding is achieved by placing the canisters within large cylindrical containers called casks. Casks are typically designed to shield the environment from the dangerous radiation in two ways. First, shielding of gamma radiation requires large amounts of mass. Gamma rays are best absorbed by materials with a high atomic number and a high density, such as concrete, lead, and steel. The greater the density and thickness of the blocking material, the better the absorption/shielding of the gamma radiation.  1, record 27, English, - blocking%20material

Intérêt du caractère discontinu du ralentissement (autoprotection en énergie). Quand on remarque les valeurs gigantesques que peuvent atteindre les sections efficaces au voisinage des pics des résonances, on peut craindre que les neutrons soient absorbés bien avant d'avoir pu se ralentir; comme ces absorptions sont pour l’essentiel des captures sans fission par l’uranium 238, cette crainte semble mettre en péril le concept même de réacteur à neutrons thermiques. En réalité, cette crainte n’est pas réellement fondée du fait que les résonances sont très élevées, certes, mais également étroites. Les neutrons se ralentissent de façon discontinue par diffusions en «sautant» d’une énergie à la suivante sans passer par les énergies intermédiaires : très souvent, ils évitent ainsi les «trappes» – les étroits domaines d’énergie où la section efficace est grande et où ils risqueraient d’être absorbés –, sans «soupçonner» le danger auquel ils ont échappé.  1, record 41, French, - autoprotection%20en%20%C3%A9nergie

Radiation damage in solids … Because the particles … have different energies and different ranges, the distance from the site of formation to the region where they cause damage is different. Thus, the size of the fissile kernels itself(also called inclusions) embedded in the inert matrix material becomes an important factor in determining the regions of damage in a material. To this end a distinction is made between a microdispersed and a macrodispersed fuel. A fuel is called microdispersed if the size of the fissile inclusions is less than 10 [micrometers], and otherwise is called macrodispersed. Microdispersed fuels can be produced either by infiltration or by compression of a mixture of matrix grains and fissile grains, while macrodispersed fuels can be produced by compression only. The damage effects in microdispersed fuels will approach those in a solid solution, while the radiation effects in macrodispersed fuels will mainly occur in the inclusions themselves and in a thin matrix layer around the inclusion, predominantly due to neutron damage.  1, record 47, English, - microdispersed%20fuel
