A new cytokinin was isolated from mature leaves of poplar. Its structure was determined by UV and MS and confirmed by synthesis as 6-(o-hydroxybenzylamino)-9-β-d-ribofuranosylpurine. This cytokinin has medium activity in the soybean ca...

Odorant receptor genes are expressed not only in the nose but also in testes, where they have been hypothesized to play a role in sperm chemotaxis. New data demonstrate that human odorant receptor hOR 17-4 may play similar roles in both...

The construction and application of a small, light, inexpensive swivel joint suitable for infusions of small laboratory animals is described. Commercially available tubes and needles are used in the construction of the swivel thus makin...

The aim of the paper is to summarize some work by the author on the theory of sugar boiling. The boiling of sugar in vacuum pans has been modelled with a set of interconnected differential and integral equations. The model equations are...

A calculation of the energy loss due to a transition from non-equilibrium to equilibrium state in the process of charging a capacitor is given. In this study, it is shown that half of the total energy produced by the battery should be c...

A covariant splitting of the total angular momentum of a spin particle into an orbital and a spin part is obtained by treating the Dirac equation as a subsidiary condition for the solutions of the Klein-Gordon equation of a spinor fiel...

The diagnostic capabilities of immuno-electron microscopy have been developed by using antibodies labelled with colloidal gold-protein A. A method termed gold-labelled antibody decoration (GLAD) is described and results using the techni...

Soliton propagation in the presence of spectral filtering, linear, and nonlinear gain is explored. We fix the filtering, and study steady-state soliton parameters for various relations between linear and nonlinear gain. We reveal, that ...

This article describes a procedure for creating sort keys for sorting items with the notation of the Superintendent of Documents Classification Scheme. The algorithm was successfully tested on five small files of SuDoc numbers. Because ...

The gain as a function of Nike Roshe Run Woven the distance between the two plates in a parallel plate channel multiplier has been investigated. The multipliers studied were found to function properly at plate distances down to 0.1 mm w...
