1. Heritability of resistance to potato late blight in an F1 population of elite potato cultivars
ABSTRACT Phytophthora infestans is the most important disease in potato crops. Its control is based on the use of chemical products that have developed pathogen resistance and high economic and environmental impacts. To reduce these effects, the use of plant varieties or cultivars resistant to this pathogen has been proposed. The aim of this study was to eva

3. Avance genético y políticas de anonimato
Resumo Nos últimos anos, o número de tratamentos de reprodução assistida com doação de gametas (óvulos e/ou espermatozoides) aumentou na Argentina. A filiação por técnicas de reprodução assistida heteróloga interroga a tradicional “herança sanguínea”, objeto de estudo privilegiado das ciências sociais. Nas últimas décadas, o paradigma d

4. Aerofoil Design for Unmanned High-Altitude Aft-Swept Flying Wings
ABSTRACT In this paper, 12 new aerofoils with varying thicknesses for an aft-swept flying wing unmanned air vehicle have been designed using a MATLAB tool which has been developed in-house. The tool consists of 2 parts in addition to the aerodynamic solver XFOIL. The first part generates the aerofoil section geometry using a combination of PARSEC and Bezier-

5. La regulación de las tecnologías reproductivas y genéticas en Argentina: análisis del debate parlamentario
Abstract This article analyzes the parliamentary debate held towards the legal regulation of reproductive and genetic techniques in Argentina (RGT). It examines the discussions in the national congress regarding the Law for Medically Assisted Reproduction, which was sanctioned in 2013, and the debate in both legislative chambers over Art. 19, which concerns

6. Occurrence of toxigenic Aspergillus flavus in commercial Bulgur wheat
Abstract Aflatoxins are mutagenic, carcinogenic, and teratogenic mycotoxins. The objective of this work was to study the presence of aflatoxigenic Aspergillus in commercial Bulgur wheat in the city of Maringá, Paraná, Brazil. Thirty samples of commercial Bulgur wheat, acquired in the period of August 2011 to January 2012, were evaluated. The enumeration an

7. Application of optimization for improvement of the efficiency of louvered-fin compact heat exchangers
Abstract A few decades ago, the product development process was just based on a trial and error procedure, and the designer's experience. The need for a new way to design and manufacture more economical and sustainable products corroborates increasingly to a new vision of how to create new products for the benefit of society. Modern numerical tools allow gre

8. An Implementation of Self-Organizing Maps for Airfoil Design Exploration via Multi-Objective Optimization Technique
ABSTRACT Design candidates obtained from optimization techniques may have meaningful information, which provides not only the best solution, but also a relationship between object functions and design variables. In particular, trade-off studies for optimum airfoil shape design involving various objectives and design variables require the effective analysis t

9. Stacking sequence optimisation of composite panels subjected to slamming impact loads using a genetic algorithm
Optimisation of stacking sequence for composite panels under slamming impact loads using a genetic algorithm method is studied in this paper. For this purpose, slamming load is assumed to have a uniform distribution with a triangular-pulse type of intensity function. In order to perform optimisation based on a genetic algorithm, a special code is written in

11. Genetic polymorphisms of NAT2, CYP2E1 and GST enzymes and the occurrence of antituberculosis drug-induced hepatitis in Brazilian TB patients
Isoniazid (INH), one of the most important drugs used in antituberculosis (anti-TB) treatment, is also the major drug involved in hepatotoxicity. Differences in INH-induced toxicity have been attributed to genetic variability at several loci, such as NAT2, CYP2E1, GSTM1 and GSTT1, that code for drug-metabolising enzymes. Our goal was to examine the polymorph

12. Optimization of laminated composite plates and shells using genetic algorithms, neural networks and finite elements
Structural optimization using computational tools has become a major research field in recent years. Methods commonly used in structural analysis and optimization may demand considerable computational cost, depending on the problem complexity. Therefore, many techniques have been evaluated in order to diminish such impact. Among these various techniques, Art
