Topics related to "node"

node
node in astronomy, point at which the orbit of a body crosses a reference plane. One reference plane that is often used is the plane of the earth's orbit around the sun ( ecliptic ). Since the moon's orbit has an inclination of 5°9′ to the plane of the ecliptic, there are two nodes in... Read more
tuber
tuber enlarged tip of a rhizome (underground stem) that stores food. Although much modified in structure, the tuber contains all the usual stem parts—bark, wood, pith, nodes, and internodes. The eyes of a potato tuber are nodes where sprouts appear, and they are arranged in the same spiral pa... Read more
corm
corm short, thickened underground stem, usually covered with papery leaves. A corm grows vertically, producing buds at the upper nodes and roots from the lower surface. Corms serve as organs of food storage and in some plants (e.g., crocus and gladiolus) of asexual reproduction; they are often mist... Read more
Hodgkin's disease
Hodgkin's disease a type of cancer of the lymphatic system . First identified in 1832 in England by Thomas Hodgkin, it is a type of malignant lymphoma. Incidence peaks in young adults and the elderly. There is some evidence that it is caused by an infection (the Epstein-Barr virus is sometimes p... Read more
runner

The runner itself usually dies at the end of the season, leaving independent new plants. Among the plants that propagate by means of runners are the strawberry, the... Read more
sarcoma
sarcoma , highly malignant tumor arising in connective- and muscle-cell tissue. It is the result of oncogenes (the cancer causing genes of some viruses) and proto-oncogenes (cancer causing genes in human cells). It may affect bone, cartilage, blood vessels, lymph nodes, and skin. See cancer ; neop... Read more
lymphatic system
lymphatic system , network of vessels carrying lymph, or tissue-cleansing fluid, from the tissues into the veins of the circulatory system. The lymphatic system functions along with the circulatory system in absorbing nutrients from the small intestines. A large portion of digested fats are absorbed... Read more
local area network
local area network (LAN), a computer network dedicated to sharing data among several single-user workstations or personal computers , each of which is called a node.

mastectomy
mastectomy , surgical removal of breast tissue, usually done as treatment for breast cancer . There are many types of mastectomy. In general, the farther the cancer has spread, the more tissue is taken. The radical mastectomies of the past (which removed not only the breast, but underlying chest mu... Read more
Kirchhoff's laws
Kirchhoff's laws [for Gustav R. Kirchhoff ], pair of laws stating general restrictions on the current and voltage in an electric circuit . The first of these states that at any given instant the sum of the voltages around any closed path, or loop, in the network is zero. The second states that at... Read more
