Light greenhouses

Benzophenone-12 stabilizer, light gel coats Bis (1,2,2,6,6-pentamethyl-4-piperidinyl) 2-(4-methoxybenzylidene) malonate stabilizer, light greenhouse 4-(2-Acryloyloxyethoxy)-2-hydroxybenzophenone polymer stabilizer, light greenhouse covers... [Pg.5742]

Modified ETEE films are used as wiadows ia greenhouses and conservatories due to their high transparency to both uv and visible light and excellent resistance to weatheriag (31). [Pg.369]

Useability of a transparent polyethylene film in hotbeds and greenhouses is obvious, since this film, as opposed to glass, displays high light permeability in the ultraviolet spectral region. [Pg.76]

The possible effects of increased atmospheric CO2 on photosynthesis are reviewed by Goud-riaan and Ajtay (1979) and Rosenberg (1981). Increasing CO2 in a controlled environment (i.e., greenhouse) increases the assimilation rate of some plants, however, the anthropogenic fertilization of the atmosphere with CO2 is probably unable to induce much of this effect since most plants in natural ecosystems are growth limited by other environmental factors, notably light, temperature, water, and nutrients. [Pg.293]

Europe s carbon market is growing quickly after the introduction of tradable annual allowances for greenhouse gas emissions under the Kyoto treaty that went into effect in 2005. In this new market-based emissiontrading system, light polluters can sell some of their surplus allowances to heavier polluters. This can result in a reduction of emissions at a lower cost than if each installation had been obliged to meet an individual target but the allowances to produce one kilowatt-hour of coal-fired power can cost more than the coal itself. [Pg.65]

In the visible light region, the transparency of neat EVAs increases as the VA content rises. The transparency in the near infrared region is weak and favours heat retention for greenhouse films. [Pg.284]

J. A frost-tender perennial usually grown as an annual in a sunny, sheltered spot or in a greenhouse. It prefers light, free-draining, fertile soil, and grows well in eontainers. Cultivars vary in leaf size, eolor, and flavor. Pinoh out shoot tips for bushy growth remove flowers to promote leaf produetion. [Pg.280]

Greenhouse gas any atmospheric gas that has the capahility of re-reflecting light reflected from the surface of the Earth hack to the Earth, thus warming it. [Pg.394]
