Hyuganatsu (Citrus tamurana, Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga , the ancient name of Miyazaki Prefecture in Kyushu , where the citrus is said to have originated, while "natsu" ( 夏 ) means summer.
Rail squeal is a sound caused by a train's wheels slipping under specific conditions, usually around sharp curves. [4] Air displacement of a train in a tunnel can create noise from turbulence. Trains also use horns, whistles, bells, and other noise-making devices for both communications and warnings.
Like the Hyuganatsu, the white pith (albedo) may be eaten. [ 4 ] The rind's cold-pressed oil has been studied for fragrance factors, and was found to contain limonene (roughly 80%), followed by the monoterpene Gamma-terpinene (10%), trans beta- farnesene , and myrcene , [ 7 ] showing similarity to Hyuganatsu's peel profile, though with ...
Road traffic occurs more often during the daytime, while train traffic can be higher in nighttime. [14] Trains cause more vibrations due to their weight and the interaction between tracks and wheels. There is a large proportion of electrical trains, leading to lower emissions near tracks than gas vehicles on roads. [14]
The correlation of these measurements indicates how much track-born noise is propagating through the ballast into the bedrock strata. This correlates directly with the noise levels experienced by surrounding area. Ground based noise systems are commonly installed near or inside tunnels.

An ETR 500 train running on the Florence–Rome high-speed line near Arezzo in Italy, the first high-speed railway opened in Europe. [50] In 1976, British Rail introduced a high-speed service able to reach 201 km/h (125 mph) using the InterCity 125 diesel-electric trainsets under the brand name of High Speed Train (HST). It was the fastest ...
