1. Molecular Modelling Study of Heteroarylamide/Sulfonamide Compounds with Antitrypanosomal Activity
According to the World Health Organization (WHO), Chagas disease (CD), whose etiological agent is the Trypanosoma cruzi (T. cruzi) parasite, affects about eight million people, mainly in Latin America. The cruzain enzyme is highlighted among the main biological targets, since it is the most abundant of the cysteine protease class from T. cruzi and is involve

2. Sobre modelagem matemática e formalismos estatísticos de sistemas complexos
Resumo Os Sistemas Dinâmicos Complexos são sistemas com propriedades emergentes inesperadas resultantes de processos sinérgicos de seus componentes. Estes sistemas aparecem na física e na química e desempenham um papel fundamental em sistemas biológicos. Tais sistemas requerem um tratamento teórico em termos de “Modelagem Matemática”, com os form

3. Modelling the growth of lactic acid bacteria at different temperatures
ABSTRACT Mathematical models are widely used to predict the shelf life of foods. Lactic acid bacteria (LAB), particularly Lactobacillus plantarum, Weissella viridescens and Lactobacillus sakei, are the main spoilage bacteria of refrigerated, vacuum-packed meat products, stored in modified atmosphere, and their growth determines the shelf life length of these

4. Environmental suitability for Lutzomyia longipalpis in a subtropical city with a recently established visceral leishmaniasis transmission cycle, Argentina
BACKGROUND Visceral leishmaniasis (VL) is an endemic disease in northeastern Argentina including the Corrientes province, where the presence of the vector and canine cases of VL were recently confirmed in December 2008. OBJECTIVES The objective of this study was to assess the modelling of micro- and macro-habitat variables to evaluate the urban environme

5. Statistical Modelling and Optimization of Fermentation Medium for Lincomycin Production by Streptomyces lincolnensis Immobilized Cells
ABSTRACT Response surface methodology was used to optimize lincomycin production by Streptomyces lincolnensis NRRL ISP-5355 in submerged fermentation. Screening of fermentation medium components to find their relative effect on lincomycin production was done using Plackett-Burman design. Malt extract, dextrin, soluble starch and (NH4)2SO4 were the most signi

6. Investigation on the Effects of Process Parameters on Laser Percussion Drilling Using Finite Element Methodology; Statistical Modelling and Optimization
Abstract In the present research, the simulation of the Nickel-base superalloy Inconel 718 fiber-laser drilling process with the thickness of 1mm is investigated through the Finite Element Method. In order to specify the appropriate Gaussian distribution of laser beam, the results of an experimental research on glass laser drilling were simulated using three

7. 3-D Geological modelling: a siliciclastic reservoir case study from Campos Basin, Brazil
Abstract Reservoir static modelling plays a fundamental role in the evaluation phase of a petroleum field. Integrated modelling allows a better understanding of how the local geology and depositional systems are related through the distribution of facies and petrophysical properties within the reservoir. In this study, geological static models of the silicic

8. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

9. Modelling the Hot Flow Behaviors of AZ80 Alloy by BP-ANN and the Applications in Accuracy Improvement of Computations
Hot compressions of as-cast AZ80 magnesium alloy in a wide temperature range of 523-673 K and strain rate range of 0.01-10 s–1 with a height reduction of 60% were conducted by a Gleeble-1500 thermo-mechanical test simulator. The hot flow behaviors show highly non-linear intrinsic relationships with temperature, strain and strain rate. In order to model the

10. EFFECTS OF CULTIVATION MEDIA COMPONENTS ON BIOSURFACTANT AND PIGMENT PRODUCTION FROM Pseudomonas aeruginosa PAO1
AbstractBiosurfactant and pigment production by P. aeruginosa have been known to be associated with its selfish growth and colonization. However, according to recent studies these products can be exploited for human benefits. In the present work the effects of culture media components on yield of these two products from P. aeruginosa PAO1 have been studied w

11. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

12. Avaliação estatística do erro de modelos de resistência para elementos lineares de concreto armado da ABNT NBR 6118:2007 / Statistical evaluation of resistance modelling error for linear elements of concrete structures of ABNT NBR 6118:2007
In a design of structures, it should be considered the intrinsic uncertainties to the present variables in the structure and in the structural concept, such as intensity and action distribution, mechanic properties of the material, geometric parameters of the structure and structural analysis and calculus models. Thus, the structural safety can only be measu
