Benzene Structure

: Triazine is the six-membered heterocyclic ring containing three nitrogen which replaces carbon-hydrogen unit in the benzene ring. Based on nitrogen position present in the ring system, it is categorized in three isomeric forms i.e.1, 2, 3-triazine (vicinal triazine), 1, 2, 4-triazine (asymmetrical triazine or isotriazine) and 1, 3, 5-triazine (symmetrical or s-triazine or cyanidine). Triazines have weakly basic property. Its isomers have much weaker resonance energy than benzene structure, so nucleophilic substitution reactions are more preferred than electrophilic substitution reactions. Triazine isomers and their derivatives are known to play important roles possessing various activities in medicinal and agricultural fields such as anti-cancer, antiviral, fungicidal, insecticidal, bactericidal, herbicidal, antimalarial and antimicrobial agents.

synopsisInhibition of central dopamine functions appears to be a common basic property of antipsychotic drugs. The mesolimbic and nigrostriatal portions of the dopaminergic system are probably the main targets of these drugs for the mental and the extrapyramidal actions respectively.Dopaminergic hyperfunction, induced by amphetamines or dopa, may lead to a disturbance mimicking paranoid schizophrenia, lending further support for a key role of dopamine in mental functions.While a primary disturbance in dopamine function in schizophrenia cannot be ruled out, the intimate relationship between dopaminergic and other neuronal systems must be emphasized. The possible involvement of other amine, aminoacid or peptide transmitters in schizophrenia cannot be disregarded.

Uncertainty Space

Uncertain processes are used to model dynamic indeterminate systems associated with human uncertainty, and uncertain independent increment processes are a type of uncertain processes with independent uncertain increments. This paper mainly verifies a basic property about the sample paths of uncertain independent increment processes, which states that uncertain independent increment processes defined on a continuous uncertainty space are contour processes, a type of uncertain processes with a spectrum of sample paths as the skeletons. Based on this property, the extreme values and the time integral of an uncertain independent increment process are investigated, and their inverse uncertainty distributions are obtained.

Basic Characteristics

Several types of oscillating water column (OWC) type wave energy converters (WECs) are researched and developed in the world. They are floating types and fixed types. In case of a fixed type, wave dissipating caissons could be replaced to WECs of an OWC type. On OWC types, installation of the projecting-walls (PWs) is useful in order to improve PTO performance. In this study, it was considered that a double dissipating caisson was used as an OWC type WEC with PWs. A front caisson of the double caisson seems the area surrounded by PWs and a back caisson can be seen as an OWC. The paper studied basic property of the primary conversion from wave power to power of air from model tests in a wave tank. As a result, wave height strongly effects on behaviours of OWC motion as well as air pressure. Finally, the primary conversion was affected by wave height. Besides, the concept of use of a double caisson was useful from the primary conversion over 80 % evaluated using test data.

ABSTRACTThe diffusion of Te and Pd was measured in the German waste glass VG 98/012 usingion implantation to introduce these elements, and the Rutherford backscattering (RBS) method to measure their diffusion. Both elements tend to precipitate during manufacture ofnuclear waste glasses, and the Te-content of the precipitates depends on the annealing time. Diffusion of these elements is a basic property of the separation phenomenon. Diffusion of both elements was found to be very slow. Te-diffusion coefficients were in the range of 10-17 to 10-15 cm2s-1 between 540 and 590 αC. Surface evaporation of Te was observed at all heat treatments. Pd diffusion was not observed in this study, most likely due to limited solubility of Pd and formation of metal precipitates.
