Greenhouse cultivation has a long history and it is difficult to appoint where the first greenhouse was built. Such an appointment directly is hindered by a good definition of a greenhouse. However, independent of a precise definition, undoubtedly, one or more orangeries at castles or palaces will be mentioned, but no one can testify whether it really ...

Greenhouse gases and greenhouse effect
Environmental Geology, 2008Conventional theory of global warming states that heating of atmosphere occurs as a result of accumu- lation of CO2 and CH4 in atmosphere. The writers show that rising concentration of CO2 should result in the cool- ing of climate. The methane accumulation has no essential effect on the Earth's climate.

Environmental Science & Technology, 1982
The climate change induced by man-made releases of carbon dioxide and other trace gases is discussed. The level of carbon dioxide in the atmosphere has increased from an estimated 293 ppm in 1880 to 335 ppm in 1980, due mainly to the increased use of fossil fuels. That level is expected to double in the next century.

Scientific American, 2009
The article discusses the release of greenhouse gases by the cattle farming industry. The generation of 13 times the amount of greenhouse gases by raising cattle compared with chicken is mentioned, noting that cattle farming generates 57 times more greenhouse gases than growing potatoes. The opinion that individuals in the U.S.

Fuzzy identification of a greenhouse
Applied Soft Computing, 2007Nonlinear dynamic systems' modelling is difficult. The solutions proposed are generally based on the linearization of the process behaviour around the operating points. Other researches were carried out on this technique of linearization not only around the operating points, but also in all the input-output space allowing the obtaining of several local
