Hanging Gardens of Babylon


The Garden is quadrangular, and each side is four plethra long. It consists of arched vaults which are located on checkered cube-like foundations.. The ascent of the uppermost terrace-roofs is made by a stairway.The Hanging Garden has plants cultivated above ground level, and the roots of the trees are embedded in an upper terrace rather than in the earth. The whole mass is supported on stone columns. Streams of water emerging from elevated sources flow down sloping channels.These waters irrigate the whole garden saturating the roots of plants and keeping the whole area moist. Hence the grass is permanently green and the leaves of trees grow firmly attached to supple branches.This is a work of art of royal luxury and its most striking feature is that the labor of cultivation is suspended above the heads of the spectators.

Radiation Therapy


In radiation therapy, radiation is directed at the parts of the body with cancer so the cells are unable to grow and divide. While all cells are affected by radiation, most normal cells can usually recover. People with cancer often receive radiation treatments 5 days a week for 2 to 9 weeks. The type of side effects the therapy may cause depends on the area of the body receiving radiation, the size of area being treated, the total dose of radiation, and the number of treatments. The following chart shows possible eating-related side effects of radiation, according to the area of body being treated. Some of these side effects can occur during treatment while others may not occur until some time after treatment.

Side effects typically start around the second or third week of treatment and peak about two-thirds of the way through treatment. After radiation therapy ends, most side effects last 2 to 3 more weeks, although some may last longer. If side effects develop, ask your doctor, nurse, or other health care professional whether medicines, a change in diet, or some other suggestion can help you manage the side effects.
