I

• Titanium is noted for its light weight, corrosion resistance, and many other desirable properties.

• The surfaces are characterized by their smooth appearance.

• Engineers are engaged in the design of superconductive bearings distinguished by the absence of friction.

• Aluminium is distinguished for its light weight.

• This bearing excels in low friction and reliability.

• The capacitor features extraordinary stability.

• The gearboxes are noteworthy for small size and ease in mounting.

• Fraunhofer diffraction is distinguished by the simplicity of the mathematical treatment required.

II

• These isomeric structures differ in the position of the methyl group attached to the five-carbon chain.

• Sand storms differ by the large mass, and by the stronger transporting winds required.
