Synthesis of polynuclear bases
Part.1 synthesis of 6-methyl-3:4-benz-5-carboline and some of its derivatives; Part. 2 synthesis of some Piperidino- and Piperazino- derivatives of quinoline

Browsing in Data Bases
Consider the tasks of trying to find similarities between the causes of the crashes of several aircraft of a common type, the causes or early warning signs for various diseases, the characteristics of stocks with high growth potential or advanced warnings of severe weather conditions. All of these …

Macaulay Bases of Modules
We introduce fully general Macaulay bases of modules, which are a common generalization of Groebner bases and Macaulay 𝐻-bases to suitably graded modules over a commutative graded k-algebra, where the index sets of the two gradings may differ. The additional generality includes Groebner bases of …

Gröbner Bases and Syzygy Modules
The theory of Gröbner bases has become a useful tool in computational commutative algebra. In this paper, we outline some basic results, as they are found in [1], including the concepts of terms ordering, multivariable polynomial division, Gröbner bases, Buchberger's algorithm, and syzygy modules. …

Bases moleculares de la propiocepción
La propiocepción es el sentido de la posición y el movimiento. Está mediado por propioceptores, un pequeño subconjunto de neuronas mecanosensoriales localizadas en los ganglios raquídeos que transmiten información sobre el estiramiento y la tensión de los músculos, tendones y articulaciones. Estas …

Effectiveness Analysis of Knowledge Bases
… and KB for knowledge base systems and knowledge bases, respectively. These models provide an environment in which we can discuss and analyze the effectiveness of a knowledge base system. This framework leads to analysis for rule set properties and a set of problem formulations for each of the …

Estructuras algebraicas con bases multiplicativas
Consideremos un álgebra arbitraria sobre la que no suponemos ningún tipo de identidad en su producto (asociatividad, Lie, etc.). Una base del álgebra se dice multiplicativa si el producto de dos elementos de la base da como resultado otro de la base multiplicado por un escalar. Mostraremos que si …

Finite bases for semigroup varieties
O objetivo deste trabalho é fornecer um atlas das bases de identidades para as variedades geradas por semigrupos e grupos de ordem pequena. Com o propósito de auxiliar os matemáticos que trabalham neste campo a encontrar informações com facilidade, foi implementado um website que executa em segundo …

Anchorage bond in concrete bases
… the anchorage bond stresses in concrete bases. In Series I to IV concrete base specimens were loaded and column starter bar strains measured for different supporting conditions of the base. Curves indicating the distribution of steel compressive stresses and bond stresses in the columns …

APPROXIMATE GROBNER BASES A BACKWARDS APPROACH
… unstable. For the the computation of exact bases for an ideal near to the one from which we began, we make avid use of structured (numerical) linear algebra. Additionally, we introduce approximate leading terms and an approximate reduced row echelon form. Neither of these require Gaussian …

Mutually Unbiased Bases in Low Dimensions
… matrices, defining a complete set of d+1 MU bases. This thesis is an exploration of sets of r≤d+1 MU bases in low dimensions. We derive all inequivalent sets of MU bases in dimensions two to five confirming that in these dimensions, the complete sets of (d+1) MU bases are unique. In dimension …

Grobner Bases and Ideals of Points
… is an introduction to the theory of Grobner bases. The concept of Grobner basis and construction of the Grobner basis by Buchberger's Algorithm, in which the notion of S-polynomials is introduced, and a few modified or improved versions of Grobner basis algorithm are reviewed in this paper. …

Replicación Autonómica de Bases de Datos
… la adaptabilidad dinámica en el contexto de las bases de datos replicadas basadas en middleware. La adaptabilidad del sistema replicado afecta principalmente a dos áreas de trabajo: La adaptación local (el control del nivel de concurrencia) y la adaptación global (el equilibrado de carga). El …

Generalizations and Applications of Border Bases
… doctoral thesis is devoted to generalize border bases to the module setting and to apply them in various ways. First, we generalize the theory of border bases to finitely generated modules over a polynomial ring. We characterize these generalized border bases and show that we can compute them. As …

Non-commutative Gröbner Bases and Applications
Commutative Gröbner bases have a lot of applications in theory and practice, because they have many nice properties, they are computable, and there exist many efficient improvements of their computations. Non-commutative Gröbner bases also have many useful properties. However, applications of …

La acción exterior local. Bases constitucionales
La acción exterior local es un fenómeno jurídico aún no estudiado entre nosotros desde la perspectiva constitucional. La doctrina se ha concentrado en el análisis de los textos internacionales y de Derecho de la Unión Europea vigentes en la materia, así como de las disposiciones legales de reciente …

The neurobiological bases of compulsive eating
Compulsive eating behavior is a transdiagnostic construct that shares many behavioral, neurobiological, and theoretical features with compulsive drug use. The focus of this dissertation is to progress a framework for compulsive eating behavior, including identification of risk factors for its …

Normal bases and compactifications of frames
The initial aim of this dissertation was to provide a frame-theoretic analogue of Banaschewski's normal systems of sets in [5] as well as a frame counterpart to their associated compactifications. Having completed this part of the task, it seemed natural to investigate the relationship between this …
