“…13 According to the definition, a Lie triple system L of an associative algebra A is a subspace of A that is closed under the ternary composition ͓͓a , b͔ , c͔, where ͓a , b͔ = ab − ba. So each case of our classification also gives the description of a classical Lie algebra in terms of a number of generators subject to certain relations.…”

Articles you may be interested inClassification of generalized quantum statistics associated with the exceptional Lie (super)algebras Statistical quantum probabilities in coherent bosonic and fermionic states A classification of generalized quantum statistics associated with basic classical Lie superalgebras Generalized quantum statistics such as para-Fermi statistics is characterized by certain triple relations which, in the case of para-Fermi statistics, are related to the orthogonal Lie algebra B n =so͑2n +1͒. In this paper, we give a quite general mathematical definition of "a generalized quantum statistics associated to a classical Lie algebra G." This definition is closely related to a certain Z-grading of G. The generalized quantum statistics is then determined by a set of root vectors ͑the creation and annihilation operators of the statistics͒ and the set of algebraic relations for these operators. Then we give a complete classification of all generalized quantum statistics associated to the classical Lie algebras A n , B n , C n , and D n . In the classification, several new classes of generalized quantum statistics are described.

“…Nos primeiros estudos fitoquímicos Spilanthes oleracea, Jacobson (1957) descreveu o "espilantol" como uma amida (N-isobutilamidas), ocorrendo também em outras espécies do gênero Spilanthes. Resultados semelhantes foram descritos por Ramsewak, Erickson e Nair (1999).…”

ResumoA produção orgânica é um sistema que permite alcançar bons níveis de produtividade, evitando ao mesmo tempo os riscos de contaminação química do agricultor, dos consumidores e do meio ambiente. Pelo fato da planta de jambu ser bastante utilizada como medicamento alternativo e por indústrias de cosméticos, vem aumentando o interesse pelo seu cultivo. Assim, o objetivo desse trabalho foi analisar a biomassa, acúmulo de nutrientes, a produtividade e determinar o resíduo de agrotóxico em plantas de jambu quando cultivado sob adubação orgânica e mineral. O experimento foi conduzido na Fazenda Experimental São Manuel, FCA/UNESP. O delineamento estatístico foi em blocos casualizados, com esquema fatorial (2 x 6), sendo duas fontes de adubação (orgânica e mineral) e seis doses de nitrogênio, com quatro repetições. As características avaliadas foram alturas de plantas, massas frescas e secas de folhas, produtividade e acúmulo de nutrientes. A adubação mineral proporcionou maior biomassa, produtividade e acúmulo de N, P e K em relação à adubação orgânica utilizada. Preconiza-se a dose de 90g m -2 de uréia como adequada para obtenção desses resultados. Com tudo a adubação orgânica favoreceu ao acúmulo de P nas plantas de jambu em relação à adubação mineral, sendo a dose de 10 kg m -2 de esterco de curral recomendada para conseguir esse resultado nas plantas de jambu. Não foi detectada a presença de agrotóxicos fosforados e carbamatos em folhas de plantas jambu sob adubação orgânica e mineral. No entanto, foi observada a presença de clorados nas folhas nas duas adubações utilizada. Palavras-chave: Spilanthes oleracea, resíduo de agrotóxico, nutrição de plantas, fertilizantes químico e orgânico AbstractThe organic production is a system that allows achieving good levels of productivity, while avoiding the risks of chemical contamination of farmers, consumers and the environment. Because jambu plant is widely used as alternative medicine and cosmetics industries, has been increasing interest in its cultivation. The aim of this study was to analyze the biomass, accumulation of nutrient, productivity and determine the pesticide residue in plant jambu when grown under organic and mineral fertilization. The experiment was conducted at the Experimental Farm São Manuel, FCA / UNESP. The experiment was conducted at São Manuel Experimental Farm UNESP. The statistical was arranged in the randomized block design, in a 2 x 6 factorial scheme, two sources of fertilizers (organic and mineral) and six doses of nitrogen, with four replications.

“…In the present study, of the three potting mixes used for rearing of the plantlets, maximum survival rate (75 %) was in the garden Pellitorine the pungent principle of A. pyrethrum was first purified from its root by Gulland and Hopton (1930). Pellitorine has been isolated and investigated for its chemical and biological properties by others also (Jacobsen 1949;Crombie 1955;Burden and Crombie 1969;Badhe et al 2010;Sharma et al 2010). In the present study, high performance liquid chromatography (HPLC) was used to analyse pellitorine in in vivo and in vitro leaves and roots of A. pyrethrum.…”

The paper reports the development of a protocol for large-scale micropropagation of Anacyclus pyrethrum, an invaluable medicinal plant, and the presence of pellitorine, the active principle, in leaves and roots of regenerated plants. Three explants-cotyledonary nodes, hypocotyls and cotyledons-were compared for their shoot development/differentiation ability on Murashige and Skoog's (MS, Physiol Plant 15:473-497, 1962) medium supplemented with 1-10 lM of 6-benzylaminopurine (BAP) or kinetin (Kn). The best response (8.88 ± 0.28 shoots per explant) was elicited from the cotyledonary nodal explants on MS ? 2.5 lM Kn. The in vitro regenerated shoots continued to multiply on being sub-cultured on the same medium. Elongated shoots were cultured on MS medium augmented with different concentrations (0.2-15 lM) of 1-naphthalene acetic acid (NAA), indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA) for induction of roots. The media augmented with 5 or 10 lM IAA or 5 lM NAA were the most effective for the initiation and proliferation of roots. The plantlets were successfully transferred to the following three potting mixtures: garden soil, vermiculite and garden soil (1:1), vermiculite, garden soil and perlite (1:1:1). Among these, the maximum number (75 %) of the transferred plants survived in the garden soil. The high performance liquid chromatographic analyses of roots and leaves of the regenerated plants as well as those from the native habitat revealed the presence of pellitorine in all, with the content being higher in the roots than the corresponding leaves.The developed protocol would be of use for production of A. pyrethrum plants throughout the year, and thus could become a perennial source of the herb and its active principle.
