While Lamb's analysis assumed a straight wavefront, it has been shown [8] that the same characteristic equations apply to cylindrical plate waves (i.e. waves propagating outwards from a line source, the line lying perpendicular to the plate). The difference is that whereas the "carrier" for the straight wavefront is a sinusoid, the "carrier ...
A cross-bred ewe suckles her lamb, which was the first of the 2008 spring lambing at a farm in Coventry, England Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram , which has either been chosen by a farmer or, in feral populations, has established dominance through physical ...
Although livestock production serves as a source of income, it can provide additional economic values for rural families, often serving as a major contributor to food security and economic security. Livestock can serve as insurance against risk [ 45 ] and is an economic buffer (of income and food supply) in some regions and some economies (e.g ...

Sheep farming in Namibia (2017). According to the FAOSTAT database of the United Nations Food and Agriculture Organization, the top five countries by number of head of sheep (average from 1993 to 2013) were: mainland China (146.5 million head), Australia (101.1 million), India (62.1 million), Iran (51.7 million), and the former Sudan (46.2 million).

Stoneley waves are most commonly generated during borehole sonic logging and vertical seismic profiling.They propagate along the walls of a fluid-filled borehole.They make up a large part of the low-frequency component of the signal from the seismic source and their attenuation is sensitive to fractures and formation permeability.
The William Davies Company facilities in Toronto, Ontario, Canada, circa 1920. This facility was then the third largest hog-packing plant in North America. The meat-packing industry (also spelled meatpacking industry or meat packing industry) handles the slaughtering, processing, packaging, and distribution of meat from animals such as cattle, pigs, sheep and other livestock.
These rumbles calm and quiet the lamb, and serve as an auditory signature as the lamb ages, a cue by which lambs can identify their own mothers. [4] Olfaction plays a role in responsiveness, as most non-maternal animals find the smell of infants and amniotic fluid repellant, while in maternal animals, those with the hormone profiles which occur ...
