1. Direct matrix-assisted laser desorption ionization time-of-flight mass spectrometry and real-time PCR in a combined protocol for diagnosis of bloodstream infections: a turnaround time approach
ABSTRACT Bloodstream infections (BSIs) are serious infections associated with high rates of morbidity and mortality. Every hour delay in initiation of an effective antibiotic increases mortality due to sepsis by 7%. Turnaround time (TAT) for conventional blood cultures takes 48 h, forcing physicians to streamline therapy by exposing patients to broad-spectru

2. Effects of abrasion on the penetration of ogival-nosed projectiles into concrete targets
This paper investigates the effects of abrasion on the penetration of an ogival-nosed projectile into concrete targets. A numerical procedure is constructed based on an abrasion model which is proposed based upon the experimental observations and a forcing function. The forcing function is a polynomial of the normal velocity which approximates the response o

3. Numerical simulation of secondary flow in pneumatic conveying of solid particles in a horizontal circular pipe
Under certain conditions, a fully developed turbulent flow in a straight pipe may show a secondary flow; for instance, when non-circular cross-section or non-uniform wall roughness around the perimeter of the duct are considered. In horizontal pipe particle-laden gas flow, the non-uniform forcing of the flow by the solids entrained in the gas core may also d

4. Variedades inerciais em um modelo atmosférico de Lorenz
Estimativas de erro são estabelecidas em termos do número de Rossby para a aproximação de Galerkin não linear nas soluções do modelo atmosférico balanceado de Lorenz com massa forçante. Desse modo a aproximação espectral da aproximação de Galerkin não linear é ligada ao número de Rossby.

5. O potencial nucleon-nucleon e a troca de dois píons relativística / Nucleon-nucleon potential and the relativistic exchange of two pions
This work is devoted to the construction of a two-pion Exchange nucleon-nucleon potential in the framework of the relativist chiral perturbation theory, formulated by Becher and Leutwyler. In their study of pion-nucleon scattering they developed a method to regain the Power counting rules while keeping Lorentz invariance. These authors also Drew attention to

6. Estudo numérico da circulação e da estrutura termohalina no Canal de São Sebastião. / Numerical study of the circulationand of the termohaline Structureat the São Sebastião Channel.
The Princeton Ocean Model was adapted to São Sebastião Channel (SSC) so as to study the seasonal changes of its circulation and thermohaline structure. Three numerical grids were nested. The coarse grid on Southeast Continental Shelf (SCS) and the fine grid on São Sebastião Channel with an intermediary grid on the region adjacent to the channel. The nume

7. Simulacoes numericas de frontogenesis / Numerical simulation of frontogenesis
Neste trabalho foram realizados experimentos numericos de frontogenese utilizando um modelo numerico multinivel de area limitada. Como forcante frontogenetica foi utilizada a deformacao horizontal do escoamento. Foram realizadas simulacoes numericas para uma atmosfera seca e com os efeitos de parametrizacao do calor latente de condensacao. Os dois experiment

8. Numerical simulation of frontogenesis / Simulacoes numericas de frontogenesis
In this study numerical simulations of frontogenesis were performed using a limited area multilevel numerical model. The frontogenetical forcing was represented by a horizontal deformation flow. The numerical experiments were run with and without the release of latent heat. In both experiments the frontogenesis at low levels and a jet at high levels a long o

10. An atmospheric pCO2 reconstruction across the Cretaceous-Tertiary boundary from leaf megafossils
The end-Cretaceous mass extinctions, 65 million years ago, profoundly influenced the course of biotic evolution. These extinctions coincided with a major extraterrestrial impact event and massive volcanism in India. Determining the relative importance of each event as a driver of environmental and biotic change across the Cretaceous-Tertiary boundary (KTB) c

11. Geologic constraints on the macroevolutionary history of marine animals
The causes of mass extinctions and the nature of taxonomic radiations are central questions in paleobiology. Several episodes of taxonomic turnover in the fossil record, particularly the major mass extinctions, are generally thought to transcend known biases in the geologic record and are widely interpreted as distinct macroevolutionary phenomena that requir
