Nonlinear reflection and refraction of planar ion-acoustic plasma solitons.

Abstract: Experimental observations on the reflection and refraction of a planar ion-acoustic soliton from a metallic mesh electrode are performed in a uniform double-plasma device. Reflection and refraction angles are observed to depend on the incident wave amplitude, showing a nonlinear Snell's law.

Polyhydroxyalkanoate synthesis from alcohols during the growth of Paracoccus denitrificans

Abstract: Several alcohols were examined as substrates for the polyhydroxyalkanoate synthesis by Paracoccus denitrificans The bacterium synthesized a homopolyester of poly(3-hydroxybutyrate) from ethanol When n-pentanol was used as growth substrate, homopolyester poly(3-hydroxyvalerate) was synthesized, whereas copolyester poly(3-hydroxybutyrate-co-3-hydroxyvalerate) accumulated during bacterial growth on n-propanol When alcohols were automatically fed as growth substrates, ethanol, n-propanol, and n-pentanol gave higher polyester content Although poly(3-hydroxybutyrate) was synthesized from methanol or n-butanol, its content was very low Under nitrogen-deficient conditions, polyester;content in cells increased, especially with ethanol, n-propanol, and n-pentanol Using a mixture of two alcohols P denitrificans could synthesize polyesters with varying relative ratios of 3-hydroxybutyrate to 3-hydroxyvalerate

Comparative study on the response of indica and japonica rice plants to ammonium and nitrate nitrogen

Abstract: The effects of NH4 + and NO3 - as nitrogen sources on the growth of two subspecies of rice, Oriza saliva subsp. Indica and Oriza saliva subsp. Japonica, during the first 6 weeks of growth were studied by the water culture method. The results obtained indicated that Indica and Japonica rice plants respond differently to NO3 -. Although both Indica and Japonica grew fairly well in solutions containing the two forms of nitrogen, the growth of the former was superior in NO3 - than in NH4 ++NO3 - or NH4 + solutions, especially at relatively low nitrogen concentrations, whereas the growth of the latter was inferior in NO3 - than in NH4 ++NO3 -solutions. In addition, plants of both subspecies fed with NH4 + showed growth retardation wtih tip-burning of the lower leaves and poorly branched roots. On the other hand, under moderately warmed glass house conditions with natural sunlight in winter, the growth of Indica in NO3 - solution was appreciably reduced compared to that in NH4 ++NO3 -. Thus, the effect...
