  3. Fragmentation (weaponry) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(weaponry)

    The correct term for those pieces is "fragments” (nicknamed “splinters” or “shards”). [1] Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and sizes and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated.

  4. Official Table of Drops - Wikipedia

    en.wikipedia.org/wiki/Official_Table_of_Drops

    The Official Table of Drops, formerly issued by the British Home Office, is a manual which is used to calculate the appropriate length of rope for long drop hangings. Following a series of failed hangings, including those of John Babbacombe Lee , a committee chaired by Henry Bruce, 1st Baron Aberdare was formed in 1886 to discover and report on ...

    This determines how fast fragments are released by military explosives, how quickly shaped charge explosives accelerate their liners inwards, and in other calculations such as explosive welding where explosives force two metal sheets together and bond them. [1]

  6. Ballistic table - Wikipedia

    en.wikipedia.org/wiki/Ballistic_table

    Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

    The restriction fragments are then ligated together. [31] A molecular marker is then generated when specific fragments are selected for amplification. AFLP markers are run alongside a DNA marker on a gel. A common AFLP DNA marker is 30-330bp long. [32] The fragments of this marker lie at 10bp intervals to increase precision. RAPD

  8. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    In granulometry, the particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. [1]

  9. US Navy decompression models and tables - Wikipedia

    en.wikipedia.org/wiki/US_Navy_decompression...

    The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
