a more speculative level, have been suggested as components of a solid-state realization of a quantum computer. The book is structured so that the reader is introduced to the methods used to produce and control quantum dots, followed by discussions of their structural, electronic, and optical properties. It concludes with examples of how their optical properties can be used in practical devices, including lasers and light-emitting diodes operating at the commercially important wavelengths of 1.3 Am and 1.55 Am.  (less)

following chapters deal with the geometrical optics model, the propagation of waves, polarization, image formation, and optical instruments. The final chapters on laser light and optical fibers show the applications of ideas developed earlier in the book. For the new third edition, the author has updated the existing text and added a chapter on the detection of light. The book aims to show how the properties of light relate to the rest of physics, and how these properties are used in many of the instruments that are among the basic tools of modern science.br1.

Also called Cilantro. Native to the Mediterranean and Middle East regions, the herb is cultivated in Europe, Morocco, and the United States. Coriander’s delicate young leaves are widely used to flavour salads, sausages, curries, pastries, liqueurs, and confectionery. Records of the use of Coriander date to 5000 BC. The Romans used the 'seeds,' actually the fruit, to flavour bread. Coriander seed is a traditional spice basic to innumerable recipes. Coriander is elemental to curry powder, Indian masalas, Ethiopian berebere, and much Latin American cuisine. The 1997 Commission E on Phytotherapy and Herbal Substances of the German Federal Institute for Drugs recommends Coriander seed for 'Dyspeptic complaints, loss of appetite.' Grieve's classic 'A Modern Herbal': 'Stimulant, aromatic and carminative. The powdered fruit, fluid extract and oil are chiefly used medicinally as flavouring to disguise the taste of active purgatives and correct their griping tendencies. It is an ingredient of the following compound preparations of the Pharmacopceia: confection, syrup and tincture of senna, and tincture and syrup of Rhubarb, and enters also into compounds with angelica gentian, jalap, quassia and lavender. As a corrigent to senna, it is considered superior to other aromatics.' 'If used too freely the seeds become narcotic.' 'Coriander water was formerly much esteemed as a carminative for windy colic.' No contra-indications are known, but it is said to be stupefying in large doses. Coriander oil can be useful to refresh and to uplift the mind. It can help for mental fatigue, migraine, tension and nervous weakness. It gives a warm effect on the stomach and can relieve wind and cramps. Coriander oil's warming effect is also helpful for alleviating pain such as rheumatism, arthritis and muscle spasms and useful with colds and flu. In vapor therapy or diluted in the bath, Coriander oil can assist with: digestive and muscle pains. As a blended massage oil Coriander oil can help with: tension, mental fatigue, migraine, muscle pains and digestive problems. Coriander oil blends particularly well with: Bergamot, Cinnamon, Ginger, Grapefruit, Lemon, Neroli and Orange. Essential and resin oils are volatile, fragrant materials extracted from the root, bark, wood, seed, fruit, leaf or flower of a single plant. Essential oils contain the odor, taste and medicinal properties of the plant itself, but in very concentrated form, with no base oil, alcohol, water or dilutants added. Steam distillation and cold pressing are used to extract the essential oil from the plant. Starwest Essential Oils are guaranteed to be 100% pure and  (less)

Whole or ground fenugreek (foenum-graecum is Latin for 'Greek hay') is traditional in Mediterranean and Indian cooking, found in most Indian curries and chutneys. A favourite Indian dish is 'methi aloo' or pan-fried potatoes flavoured with fenugreek. It is also a basic Indian pickling spice. Fenugreek is also sprouted and used in salads, providing an excellent source of Vitamin E. Fenugreek's steroidal saponins account for many of its beneficial effects, particularly the inhibition of cholesterol absorption and synthesis. The seeds are rich in dietary fiber, which may be the main reason they can lower blood sugar and cholersterol levels. This remarkable property has been confirmed in more than one modern study. The 1997 Commission E on Phytotherapy and Herbal Substances of the German Federal Institute for Drugs recommends Fenugreek seed for 'Internal: Loss of appetite. External: As poultice for local inflammation.' 'Side Effects: Repeated external applications can result in undesirable skin reactions. 'Dosage: Internal: 6 g drug; equivalent preparations. External: 50 g powdered drug with ¼ liter water. Mode of Administration: Liniments in the form of alcoholic solutions, ointments, gels, emulsions, oils. Also bath additive and as an inhalant.' 'Actions: Secretolytic; Hyperemic; Mild antiseptic.' Grieve's classic 'A Modern Herbal': 'In Cairo it is used under the name of Helba. This is an Egyptian preparation, made by soaking the seeds in water till they swell into a thick paste. Said to be equal to quinine in preventing fevers; is comforting to the stomach and has been utilized for diabetes.
