This magnetic energy value is about 18 times greater than "ordinary" ferrite magnets by volume and 12 times by mass. This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend ...
The AlNiCo technically have a slightly stronger field (specifically, increased magnetic flux density), but they become demagnetized easily in the presence of other magnetic fields. Because NdFeB magnets have comparable strength and do not demagnetize as easily, they have largely replaced AlNiCo magnets, especially in applications where there is ...
N52 (Long Island bus) BMW N52, an automobile engine; HMS Trident (N52), a submarine of the Royal Navy; HNoMS Vidar (N52), a minelayer of the Royal Norwegian Navy; Nostromo SpeedPad n52, a computer gaming peripheral; Okamura N-52, a Japanese sport aircraft; Neodymium magnet grade for one of the strongest (N30-N55) types
Given a set of contigs, the N50 is defined as the sequence length of the shortest contig at 50% of the total assembly length. It can be thought of as the point of half of the mass of the distribution; the number of bases from all contigs longer than the N50 will be close to the number of bases from all contigs shorter than the N50. For example ...
To emphasize the point, consider the issue of choosing a material for building an airplane. Aluminum seems obvious because it is "lighter" than steel, but steel is stronger than aluminum, so one could imagine using thinner steel components to save weight without sacrificing (tensile) strength.
Strengthening of materials is useful in many applications. A primary application of strengthened materials is for construction. In order to have stronger buildings and bridges, one must have a strong frame that can support high tensile or compressive load and resist plastic deformation.
These paper grades have lower coat weights than the standard WFC (3–14 g/m 2 /side) and the grammage and pigment content are also generally lower, 55–135 g/m 2 and 20–35% respectively. Art paper s Art papers are one of the highest-quality printing papers and are used for illustrated books, calendars and brochures.
The telephone cables have a large number of conductors that are individually insulated. The paper needs to be thin (30-40 g/m 2). A normal power cable needs more insulation and therefore paper with higher paper density is used, normally 60-190 g/m 2. The paper needs to be strong, elastic, uniform and free of holes or debris.
