1. Peticiones y prerrogativas Médicos y boticarios en la corporativización del arte de curar y la conformación del Estado provincial en Santa Fe, Argentina (1857-1903)
Abstract In this article we seek to investigate a particular aspect of medical professionalization in the province of Santa Fe (Argentina): authorization processes and specific requests from different professionals to act as qualified specialists. To do this, we will address a series of applications submitted by doctors and apothecaries during the second hal

2. Rheological characteristics PBAT/organoclay compounds
Abstract The rheological behavior of poly (butylene adipate-co-terephthalate) (PBAT) and its composites prepared with three different organoclays was investigated. Composites containing up to 7.5%, w/w organoclay, were prepared by two routes: (a) direct melt blending in an internal laboratory mixer with high intensity rotors and (b) concentrates (prepared in

3. Reduced-order strategy for meshless solution of plate bending problems with the generalized finite difference method
Abstract This paper presents some recent advances on the numerical solution of the classical Germain-Lagrange equation for plate bending of thin elastic plates. A meshless strategy using the Generalized Finite Difference Method (GFDM) is proposed upon substitution of the original fourth-order differential equation by a system composed of two second-order par

4. Geophysical modeling in gold deposit through DC Resistivity and Induced Polarization methods
Abstract Ore mining fundamentally depends on the definition of its tenor and volume, something extremely complex in disseminated mineralization, as in the case of certain types of deposits of gold and sulfites. This article proposes the use of electrical tomography for definition of a geophysical signature in terms of electrical resistivity and chargeability

5. A STUDY OF PYROLYSIS OF MACADAMIA NUT SHELL: PARAMETRIC SENSITIVITY ANALYSIS OF THE IPR MODEL
Abstract The macadamia tree is known for producing fruit high in fats, enclosed in very hard woody shells. Macadamia nut shell, considered as a by-product from macadamia nut processing, may be a suitable option for pyrolysis. These residues are constituted of cellulose, hemicellulose, lignin and extractives. The Independent Parallel Reaction (IPR) Model has

6. The influence of long chain branches of LLDPE on processability and physical properties
Two polyethylene-based on single-site metallocene catalyst (mLLDPE) were selected to characterize the effect of long chain branching (LCB) on blown film processability, optical and mechanical properties. 13C NMR and parallel plate rheology were used to identify LCB presence on LLDPEs. Blown films were produced from 100% LLDPEs using three different machine d

7. Geração de b-splines via FPGA / B-spline generation via FPGA
The b-splines are used in CAD/CAM/CAE systems to represent and define complex curves and surfaces, being adopted by the main computer graphics standards due to features like compact mathematic representation, flexibility and affine transformations. In 3D acquisition systems and integrated CAM-CNC systems, the use of the b-spline in the geometric information

8. ESTRATÉGIAS PARALELAS INTELIGENTES PARA O MÉTODO BRANCH-AND-BOUND APLICADAS AO PROBLEMA DO CAIXEIRO VIAJANTE ASSIMÉTRICO / PARALLEL STRATEGIES FOR INTELLIGENT METHOD BRANCH-AND-BOUND TO APPLY traveling salesman problem ASYMMETRICAL
To the use of different architectures to process distinct portions of the same code, in order to maximize the performance, it is given the name Heterogeneous Computing. The Heterogeneous Computing is closely related to the high performance computing, and raised in a moment when the parallel computers, in that time with homogeneous execution, could no longer

9. Mecanismo para execução especulativa de aplicações paralelizadas por técnicas DOPIPE usando replicação de estágios / Mechanism for speculative execution of applications parallelized by DOPIPE techniques using stage replication
A utilização máxima dos núcleos de arquiteturas multi-processadas é fundamental para permitir uma utilização completa do paralelismo disponível em processadores modernos. A fim de obter desempenho escalável, técnicas de paralelização requerem um ajuste cuidadoso de: (a) mecanismo arquitetural para especulação; (b) ambiente de execução; e (c)

10. Implementação paralela do algoritmo iterativo de busca do parâmetro de regularização ótimo para o funcional de Tikhonov no problema de restauração de imagens / Parallel implementation of the iterative algorithm to search the optimal regularization parameter for the Tikhonov functional problem in image restoration
The use of techniques with the functional of Tikhonov in image processing has been widely used in recent years. The basic idea in this process is to modify an initial image using a convolution equation and to find a parameter which minimizes the function in order to obtain an aproximation of the original image. However, a typical problem in this method consi

12. A study on the extension of an upwind parallel solver for turbulent flow applications
The present work is primarily concerned with studying the influence of an upwind spatial discretization on the capability of representing turbulent flows on aerospace applications, in the context of a flow simulation code that is fairly close to a production code. Therefore, the work addresses the issues of implementing and validating an advanced turbulence
