The 2-8-2 wheel arrangement allowed the locomotive's firebox to be placed behind instead of above the driving wheels, thereby allowing a larger firebox that could be both wide and deep. This supported a greater rate of combustion and thus a greater capacity for steam generation, allowing for more power at higher speeds.
Smith–Magenis syndrome (SMS), also known as 17p- syndrome, is a microdeletion syndrome characterized by an abnormality in the short (p) arm of chromosome 17. [1] It has features including intellectual disability, facial abnormalities, difficulty sleeping, and numerous behavioral problems such as self-harm.
The first four partial sums of 1 + 2 + 4 + 8 + ⋯. In mathematics, 1 + 2 + 4 + 8 + ⋯ is the infinite series whose terms are the successive powers of two. As a geometric series, it is characterized by its first term, 1, and its common ratio, 2. As a series of real numbers it diverges to infinity, so the sum of this series is infinity.
The 2-8-0 locomotive was used extensively throughout Australia. It served on the 5 ft 3 in (1,600 mm) broad gauge, 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge and 3 ft 6 in (1,067 mm) narrow gauge and was employed mostly as a freight locomotive, although it was often also employed in passenger service in Victoria.

Chromosome 1 is the designation for the largest human chromosome.Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes.
IQ scores can differ to some degree for the same person on different IQ tests, so a person does not always belong to the same IQ score range each time the person is tested (IQ score table data and pupil pseudonyms adapted from description of KABC-II norming study cited in Kaufman 2009).
These changes include an extra copy of part of chromosome 7 in each cell (partial trisomy 7) or a missing segment of the chromosome in each cell (partial monosomy 7). In some cases, several DNA building blocks ( nucleotides ) are deleted or duplicated in part of chromosome 7.
Cat-eye syndrome (CES) or Schmid–Fraccaro syndrome is a rare condition caused by an abnormal extra chromosome, i.e. a small supernumerary marker chromosome. [2] This chromosome consists of the entire short arm and a small section of the long arm of chromosome 22.
