In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

Naturally occurring neodymium (60 Nd) is composed of five stable isotopes— 142 Nd, 143 Nd, 145 Nd, 146 Nd and 148 Nd, with 142 Nd being the most abundant (27.2% of the natural abundance)—and two radioisotopes with extremely long half-lives, 144 Nd (alpha decay with a half-life (t 1/2) of 2.29 × 10 15 years) and 150 Nd (double beta decay, t ...
Neodymium nitrate is an inorganic compound with the formula Nd(NO 3) 3 ·(x(H 2 O). It is typically encountered as the hexahydrate, Nd(NO 3) 3 ·6H 2 O, which is more accurately formulated as [Nd(NO 3) 3 (H 2 O) 4].2H 2 O to reflect the crystal structure. [1] It decomposes to NdONO 3 at elevated temperature. [2]

The company supplied melt-spun Nd 2 Fe 14 B powder to bonded magnet manufacturers. The Sumitomo facility became part of Hitachi, and has manufactured but also licensed other companies to produce sintered Nd 2 Fe 14 B magnets. Hitachi has held more than 600 patents covering neodymium magnets. [9]
On these highways, Federal width and length limits apply. The National Network (NN) includes almost all of the Interstate Highway System and other, specified non-Interstate highways. The network comprises more than 200,000 miles (320,000 km) of highways.
Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd 2 O 3. It forms very light grayish-blue hexagonal crystals. [ 1 ] The rare-earth mixture didymium , previously believed to be an element , partially consists of neodymium(III) oxide.
The Holliday-Segar formula is a formula to help approximate water and caloric loss (and therefore the water requirements) using a patient's body weight. [1] Primarily aimed at pediatric patients, the Holliday-Segar formula is the most commonly used estimate of daily caloric requirements. [2]
