Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
Tube cleaning describes the activity of, or device for, the cleaning and maintenance of fouled tubes. [1] The need for cleaning arises because the medium that is transported through the tubes may cause deposits and finally even obstructions. In system engineering and in industry, particular demands are placed upon surface roughness or heat ...
The liliger is the hybrid offspring of a male lion (Panthera leo) and a female liger (Panthera leo♂ × Panthera tigris♀). Thus, it is a second generation hybrid. In accordance with Haldane's rule, male tigons and ligers are sterile, but female ligers and tigons can produce cubs.
The liger is a hybrid offspring of a male lion (Panthera leo) and a tigress, or female tiger (Panthera tigris). The liger has parents in the same genus but of different species . The liger is distinct from the opposite hybrid called the tigon (of a male tiger and a lioness), and is the largest of all known extant felines .
This can be used for pet stains and out of doors. [3] There is no chief underlying chemical reason why club soda would be superior to plain water in stain removal. [8] Glycerine This can be used to soften "set" stains, especially on wool and non-water-washable fabrics. [3] Boiling water This can be used to take out fruit juice stains.
Copper tubes have been used to distribute potable water within building for many years and hundreds of miles are installed throughout Europe every year. The long life of copper when exposed to natural waters is a result of its thermodynamic stability, its high resistance to reacting with the environment, and the formation of insoluble corrosion products that insulate the metal from the ...
The male liger and tigon are both sterile as a mule. Females can be fertile and can produce Ti-ligers or Ti-tiglons. This is true with most hybrids nature for some reason wants to protect itself That may have to do with the X and Y chromosomes, maybe the Y chromosome creates sterility?
Ligers and tigons were long thought to be sterile; in 1943, however, a 15-year-old hybrid between a lion and a tiger was successfully mated at the Munich Hellabrunn Zoo. The female cub was then raised to adulthood. [2] Like the liger, male tigons are sterile while the females are fertile.
