Botha, then South Africa's foreign minister, introduced the "Bantu Homelands Citizenship Bill" in 1969 linking blacks to tribal sites of origin, or "Bantustans," seeking thereby to separate the races permanently.
Malignant tumours arising elsewhere in the body may metastasize to the brain; common sites of origin of such secondary tumours are the lung, breast, thyroid, and kidney.
The oxygen that is dissolved in seawaters at the surface sites of origin of bottom water in concentrations of 4 to 6 millilitres per litre is the sole source of this element for benthic life.
These data indicate that PACAP38 has two sites of origin unlike VIP: the parasympathetic system and the sensory system.
Cells migrate radially and tangentially from their sites of origin to generate these structures; this process is only completed postnatally.
Others take issue with the results because none of the ancient samples come from the other putative sites of origin.
An exquisitely intricate temporal relationship among these signaling modalities with varied sites of origin is paramount in sustenance of weight control on a daily basis.
Among sinonasal melanoma the most common sites of origin are the nasal septum, lateral nasal wall, paranasal sinuses, and the inferior and middle turbinates.
The mucosa investing the middle turbinate, the uncinate process and the ethmoid infundibulum are the most usual sites of origin of polyps.
Its objective is to map the sites of origin of the ENP of the icy moons' exospheres to investigate the interaction between the surface and the environment.
During tumour metastasis, a critical early step is cell invasion of the basement membrane - a dense meshwork of collagen, glycoproteins, and proteoglycans which, under normal circumstances, prevents cells from moving away from their sites of origin.
