Blood Knot is an early play by South African playwright, actor, and director Athol Fugard. Its single-performance premier was in 1961 in Johannesburg , South Africa , with the playwright and Zakes Mokae playing the brothers Morris and Zachariah.
The use of cord blood stem cells in treating conditions such as brain injury [39] and Type 1 Diabetes [40] is already being studied in humans, and earlier stage research is being conducted for treatments of stroke, [41] [42] and hearing loss. [43] Cord blood stored with private banks is typically reserved for use of the donor child only.
Blood knot (barrel knot) – joins sections of monofilament nylon line while maintaining much of the line's inherent strength; Blood loop knot (dropper loop) – forms a loop which is off to the side of the line; Boa knot – binding knot; Boom hitch – attach a line to a fixed object like a pipe
Knots can be described in various ways. Using different description methods, there may be more than one description of the same knot. For example, a common method of describing a knot is a planar diagram called a knot diagram, in which any knot can be drawn in many different ways.
A petal projection is a description of a knot as a special kind of knot diagram, a two-dimensional self-crossing curve formed by projecting the knot from three dimensions down to a plane. In a petal projection, this diagram has only one crossing point, forming a topological rose. Every two branches of the curve that pass through this point ...
The glomerulus (pl.: glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons. The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of intraglomerular mesangial cells.
Image showing trophoblast differentiated into the two layers of cytotrophoblast and syncytiotrophoblast during implantation. It is the outer layer of the trophoblasts and actively invades the uterine wall, during implantation, rupturing maternal capillaries and thus establishing an interface between maternal blood and embryonic extracellular fluid, facilitating passive exchange of material ...
In the mathematical subject of knot theory, the average crossing number of a knot is the result of averaging over all directions the number of crossings in a knot diagram of the knot obtained by projection onto the plane orthogonal to the direction. The average crossing number is often seen in the context of physical knot theory.
