In vitro pathogenicity of northern Peru native bacteria on Phyllocnistis citrella Stainton (Gracillariidae: Phyllocnistinae), on predator insects ( Hippodamia convergens and Chrisoperna externa), on Citrus aurantifolia Swingle and white rats
(Instituto Nacional de Investigación y Tecnología, 2009)
In Peru, the leaf miner Phyllocnistis citrella attacks citrus crops, including the economically important species
Citrus aurantifolia, adversely affecting production. The objective of this work was to determine the in ...
Relation of Gallbladder Motility to Viscosity and Composition of Gallbladder Bile in Patients with Cholesterol Gallstones
(Social Science Research Network, 2009)
Background/Aims: Increased viscosity and supersaturation of cholesterol in gallbladder bile, as well as an impaired motility of the gallbladder, are considered to be important factors in the pathogenesis of cholesterol ...
Standard General Relativity from Chern–Simons Gravity
(Cornell University Library, 2009)
Chern–Simons models for gravity are interesting because they provide with a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largely been the perceived remoteness from ...
Dual Formulation of the Lie Algebra S-expansion Procedure
(Cornell University Library, 2009)
Thevexpansion of a Lie algebra entails finding a new, bigger algebra G, through a series of well-defined steps, from an original Lie algebrag. One incarnation of the method, the so-called S-expansion, involves the use of ...
Principal Poincaré–Pontryagin function associated to polynomial perturbations of a product of (d+1)(d+1) straight lines
(Elsevier, 2009)
In this paper, we study small polynomial perturbations of a Hamiltonian vector field with Hamiltonian F formed by a product of (d+1)(d+1) real linear functions in two variables. We assume that the corresponding lines are ...
Generating Higher-Order Lie Algebras by Expanding Maurer Cartan Forms
(Cornell University Library, 2009)
By means of a generalization of the Maurer-Cartan expansion method we construct a procedure to obtain expanded higher-order Lie algebras. The expanded higher order Maurer-Cartan equations for the case G=V0⊕V1 are found. A ...
Stability results for polyhedral complementarity problems
(Elsevier, 2009)
In this work, we study the multivalued complementarity problem for polyhedral multifunctions under homogeneity assumptions. We employ an approach that consists in approximating the equivalent variational inequality formulation ...
Obstrucción intestinal por Ascaris Lumbricoides
(Scielo, 2009)
Varón de 71 años, sin antecedentes morbidos, ingresa al Servicio de Urgencia del Hospital Clínico Herminda Martín por cuadro de siete días de evolución caracterizado por ausencia de deposiciones, dolor abdominal, vómitos ...
S-Expansion of Higher-Order Lie Algebras
(Cornell University Library, 2009)
By means of a generalization of the S-expansion method we construct a procedure to obtain expanded higher-order Lie algebras. It is shown that the direct product between an Abelian semigroup S and a higher-order Lie algebra ...
Variabilidad de las comunidades de parásitos metazoos del róbalo Eleginops maclovinus (Cuvier & Valenciennes, 1830) (Pisces: Eleginopidae) en Chile
(Scielo, 2009)
La comparación de las variaciones en el tiempo cronológico y en el espacio es uno de los aspectos menos
estudiados en la ecología de las comunidades de parásitos. Por eso, en este estudio se compara la abundancia
total, ...
