Modernist Success in a Postmodern Failure: Jackson Pollock and Abstract Expressionism, the Avant-Garde and the Ascension of Late Capitalism, Art after 1945

It is hard to imagine the magnitude of the events at the end of World War II. The thought produced in the face of a myriad of deaths is almost unfeasible sixty years after the fact, but the energy was integral to the changing social landscape. Because of the country's prominence in and fortitude after the war, the U.S. was left responsible for reshaping and rejuvenating the international landscape that was destroyed by the years of brutal fighting and vile contestation. The American establishment was granted a major opportunity to establish itself amongst the global leaders. Such a grand responsibility must account for the multiplicity of thought that arises in such a decisive moment. In order to align the Abstract Expressionist art movement with the intersection of the intense, multifaceted thought developed during the postwar period, the following will discuss the political, philosophical, economic, and art historical overlap that occurred in the mid to late 1940s in the hopes of illustrating the fertility yet lingering problems associated with the restructuring of the world with America at the helm. In this way, the duration of the Abstract Expressionist moment will be better understood for both its triumphs and downfalls.

Aceitabilidade de formulações de baião-de-dois elaboradas a partir de arroz integral e feijão caupi biofortificados.

O objetivo deste trabalho foi analisar sensorialmente formulações de baião-de-dois elaborados a partir de arroz integral e feijão-caupi biofortificados. Foram analisadas amostras de cinco formulações de baião-de-dois: baião padrão (arroz polido comercial + feijão-caupi comercial); baião controle (arroz integral comercial + feijão-caupi comercial); baião 1 (arroz integral Chorinho + feijão-caupi BRS Aracê); baião 2 (arroz integral Chorinho + feijão-caupi BRS Tumucumaque); e baião 3 (arroz integral Chorinho + feijão-caupi BRS Xiquexique).

Os maus-tratos ao idoso no ambiente domiciliar e a educação popular em saúde como forma de intervenção na ESF Jackson Martins (Sarapuí).

Os maus-tratos ao idoso no ambiente familiar constituem um problema de saúde pública e têm aumentado com o envelhecimento da população. Ações de intervenção buscando resolver esse problema requerem prévio conhecimento sobre a sua dimensão e maneira como grupos específicos são por ele afetados. Foi percebida no ESF Jackson Martins (Sarapuí), durante as visitas domiciliares (VDs) e o atendimento, uma grande proporção de idosos sofredores de maus-tratos. Essa relacionada à falta de informação de seus cuidadores sobre fatores de risco e medidas preventivas. Isso poderia ser resolvido através da troca de experiências entre comunidade e profissionais na busca pela melhoria da qualidade de vida dos assistidos. Haveria assim, no ESF Sarapuí a produção de conhecimento a fim de diminuir o número de idosos sofredores de maus-tratos no ambiente domiciliar. Nesse cenário, seria colocado em prática o conceito de Educação Popular em Saúde e sua metodologia de problematização e participação de profissionais e comunidade na busca por soluções. Essa seria implementada de forma integral e continuada, respeitando a realidade e os interesses da população.

Integral Piezoactuator System with Optimum Placement of Functionally Graded Material - A Topology Optimization Paradigm

Piezoactuators consist of compliant mechanisms actuated by two or more piezoceramic devices. During the assembling process, such flexible structures are usually bonded to the piezoceramics. The thin bonding layer(s) between the compliant mechanism and the piezoceramic may induce undesirable behavior, including unusual interfacial nonlinearities. This constitutes a drawback of piezoelectric actuators and, in some applications, such as those associated to vibration control and structural health monitoring (e. g., aircraft industry), their use may become either unfeasible or at least limited. A possible solution to this standing problem can be achieved through the functionally graded material concept and consists of developing `integral piezoactuators`, that is those with no bonding layer(s) and whose performance can be improved by tailoring their structural topology and material gradation. Thus, a topology optimization formulation is developed, which allows simultaneous distribution of void and functionally graded piezoelectric materials (including both piezo and non-piezoelectric materials) in the design domain in order to achieve certain specified actuation movements. Two concurrent design problems are considered, that is the optimum design of the piezoceramic property gradation, and the design of the functionally graded structural topology. Two-dimensional piezoactuator designs are investigated because the applications of interest consist of planar devices. Moreover, material gradation is considered in only one direction in order to account for manufacturability issues. To broaden the range of such devices in the field of smart structures, the design of integral Moonie-type functionally graded piezoactuators is provided according to specified performance requirements.

Calculation of line integrals in boundary integral methods

Spectral properties of the tandem Jackson network, seen as a quasi-birth-and-death process

Quasi-birth-and-death (QBD) processes with infinite “phase spaces” can exhibit unusual and interesting behavior. One of the simplest examples of such a process is the two-node tandem Jackson network, with the “phase” giving the state of the first queue and the “level” giving the state of the second queue. In this paper, we undertake an extensive analysis of the properties of this QBD. In particular, we investigate the spectral properties of Neuts’s R-matrix and show that the decay rate of the stationary distribution of the “level” process is not always equal to the convergence norm of R. In fact, we show that we can obtain any decay rate from a certain range by controlling only the transition structure at level zero, which is independent of R. We also consider the sequence of tandem queues that is constructed by restricting the waiting room of the first queue to some finite capacity, and then allowing this capacity to increase to infinity. We show that the decay rates for the finite truncations converge to a value, which is not necessarily the decay rate in the infinite waiting room case. Finally, we show that the probability that the process hits level n before level 0 given that it starts in level 1 decays at a rate which is not necessarily the same as the decay rate for the stationary distribution.

A finite integral transform technique for solving the diffusion-reaction equation with Michaelis-Menten kinetics

An approximate analytical technique employing a finite integral transform is developed to solve the reaction diffusion problem with Michaelis-Menten kinetics in a solid of general shape. A simple infinite series solution for the substrate concentration is obtained as a function of the Thiele modulus, modified Sherwood number, and Michaelis constant. An iteration scheme is developed to bring the approximate solution closer to the exact solution. Comparison with the known exact solutions for slab geometry (quadrature) and numerically exact solutions for spherical geometry (orthogonal collocation) shows excellent agreement for all values of the Thiele modulus and Michaelis constant.
