Computer Study of Cluster Mechanism of Anti-greenhouse Effect
نویسنده
چکیده
Absorption spectra of infra-red (IR) radiation of the disperse water medium absorbing the most important greenhouse gases: 2 CO , O N2 , 4 CH , 2 2H C , 6 2H C have been calculated by the molecular dynamics method. Loss of the absorbing ability at the formation of clusters due to a reduction of the number of centers interacting with IR radiation, results in an anti-greenhouse effect. Absorption of 3 O molecules by the 50 2O) (H cluster is investigated at its interaction with Cl ions. The splitting of ozone molecule on atoms near to cluster surface was observed. Interaction of water cluster with Cl ions causes the increase of integrated intensity of emission spectra of IR radiation, and also essential reduction of the similar characteristic of Raman spectrum. Relative integrated intensity of absorption of IR radiation for small water clusters was designed. Dependences of the quantity of weight on altitude for vapor of monomers, clusters, droplets, crystals and mass of all moisture were determined. The anti-greenhouse effect of clusters was defined as the difference of increases of average global temperature of the Earth, caused by absorption of IR radiation by free water molecules forming clusters, and absorption of clusters themselves. The greenhouse effect caused by clusters makes 0.53 K, and the antigreenhouse one is equal to 1.14 K. The increase of concentration of 2 CO in the atmosphere does not always correlate with the amplification of greenhouse effect. Keywords—Greenhouse gases, infrared absorption and Raman spectra, molecular dynamics method, water clusters.

Recent studies have shown that intracerebroventricular administration of cimetidine (CIM) induces anti-nociceptive and anti–inflammatory effects in rats. However, the underlying mechanism of CIM effect has not been determined yet. This study was planned to determine the anti-nociceptive effect of CIM (50 mg/kg, i.p.) in male mice (25-30 g, n = 80) using tail flick test. Also, the role of ATP-se...
