Although surface roughness, vegetation and soil texture have been established as sources of variability in passive microwave interpretation, soil organic carbon (SOC) has not typically been considered as a factor that affects SWC estimation during field sampling campaigns.
The embryonic stem cells (ESCs) have been established as sources to study a variety of endocrine systems, towing to their pluripotent ability to produce a seemingly unlimited supply of specific lineage of cell types, amenability to genetic engineering manipulations and broad developmental potential.
Jokes that circulate by e-mail, especially off-color ones, are not only frowned upon but have also been established as a source of legal liability.
"The bone marrow, peripheral blood, and cord blood have been established as suitable sources of hematopoietic stem cells for transplantation," says Dr. William Hwang of the Department of Haematology at SGH. "Studies have shown that these may also be sources of totipotent cells, which can differentiate into other mesenchymal tissues.
LEDs have been established as light sources in countless areas of optical sensing and chemical analysis, where they offer a better alternative to traditional light sources in terms of low-cost, small size and robustness supporting portability, and performance parameters such as low noise.
Therefore, forest resources, particularly the non-timber forest products (NTFPs) have been established as an essential source of livelihood for the majority of forest-dependent communities among others.
Copy number variants have been established as an important source of mutation in other complex brain disorders, including intellectual disability, autism and schizophrenia.

Consumption of contaminated maize was established as the source of aflatoxin exposure.
