1. Resistance of cocoa to Moniliophthora perniciosa – progenitors and progenies selection
ABSTRACT Witches' broom, caused by Moniliophthora perniciosa, is the most important cacao disease in Brazil, and the final objective of this study is increasing the level and durability of resistance to this fungus, through the association of different alleles or genes favorable to the character, for the generation of new cocoa varieties. It was conducted, f

2. Soil stabilization with lime for erosion control in solar plants
Abstract The installation of solar parks requires extensive areas and results in soil erosion in many cases. One suitable solution is applying lime to improve soil characteristics, such as mechanical strength, stability, workability, durability, and internal and surface erosion resistance. This soil treatment is of particular importance when dealing with hyd

4. The Role of Free Proline and Soluble Carbohydrates in Water Gypsum Stress on Some Gypsophyte and Gypsovag Plants
RESUMO: O objetivo deste estudo é investigar o papel da prolina livre e dos carboidratos solúveis em condições de estresse gesso. Inicialmente, foram analisadas as prolinas e carboidratos contidos em gipsita e gipsovaque. Prolinas são compostos que contêm nitrogênio, produzidos sob condições de estresse, com propriedades de proteção e que contribu

5. Caracterização de genótipos de soja com resistência parcial à ferrugem da soja
RESUMO A ferrugem asiática da soja (FAS), causada pelo fungo Phakopsora pachyrhizi, é uma das doenças mais severas na cultura. Dentre as estratégias para seu manejo propõe-se a utilização de genótipos com resistência horizontal ou parcial, ainda restritos no mercado, mas promissores pela durabilidade da resistência. O objetivo deste trabalho foi av

6. Optimal hydrated lime concentration in asphalt binder to improve photo degradation resistance
Abstract The effect of short-term oxidation, evaluated by using a Rolling Thin Film Oven Test, and the effect of weathering aging on the oxidation process of hydrated lime modified asphalts were studied. Hydrated lime (HL) has been known as an additive for asphalt mixtures and is now considered as a binder additive that increases asphalt mixture durability.

7. Improvement of Titanium Corrosion Resistance by Coating with Poly-Caprolactone and Poly-Caprolactone/Titanium Dioxide: Potential Application in Heart Valves
Heart diseases affect part of world population and generally involves the functioning of valves. Valves replacement is the most common treatment and the choice between synthetic or natural/biological implants depends on several factors. Synthetic implants have greater durability, whereas biological ones are more biocompatible. This work proposes the use of p

8. Tensile Behaviour and Durability Issues of Engineered Cementitious Composites with Rice Husk Ash
ABSTRACT The Engineered Cementitious Composites (ECC) is a special type of High Performance Fibre Reinforced Cementitious Composite (HPFRCC) characterized by a high tensile ductility with a 2% maximum volume of micro fibres. ECC has a tensile strain-hardening performance that leads to multiple cracking behaviour, thus providing the high ductility to the conc

9. Physicochemical Characterization of Pulverized Phyllite Rock for Geopolymer Resin Synthesis
Geopolymeric materials have some unique properties such as early-high compressive strength, durability, resistance to acids and sulfates, ability to immobilize toxic and radioactive compounds, low porosity and high temperature resistance. These materials are strategic for sustainable development and are a suitable alternative to Portland cement. The use of p

10. Finite Element Analysis of Structures with Extruded Aluminum Profiles Having Complex Cross Sections
Abstract Extruded aluminum profiles are widely used in building and automation structures due to their durability, lightweight, corrosion resistance, shorter fastening time and reusability. Proper design is crucial in maintaining the lifespan of these structures. It is therefore essential to determine the structural behaviors of the structures such as the na

11. Biodegradation of additive PHBV/PP-co-PE films buried in soil
Abstract There is considerable concern about the impact plastic materials have on the environment due to their durability and resistance to degradation. The use of pro-oxidant additives in the polymer films could be a viable way to decrease the harmful effects of these discarded materials. In this study, films of PHBV/PP-co-PE (80/20 w/w) and PHBV/PP-co-PE/a

12. Cacao families and parents selected as resistant to natural infection of Moniliophthora perniciosa
Abstract The known sources of resistance to witches' broom (WB), a severe disease of cacao, are limited. Aiming to identify families and parents resistant to Moniliophthora perniciosa, a population of 22 families was evaluated by assessing the number of brooms formed per tree during 10 years under field conditions. The population was established in randomize
