26. Mineralogical and chemical attributes of soils from the Brazilian Atlantic Forest domain
ABSTRACT: The Atlantic Forest is one of the most important and yet the most devastated Brazilian biome, occupying in the past the majority of the East Atlantic Coast. Therefore, a detailed knowledge of the soils near the coastal line influenced by this biome is essential for land use and management of these environments. The aim of this study was to acquire

27. Technologies for Jatoba Seedling Formation
ABSTRACT This research evaluated protected environment and substrates for jatoba seedling. Two protected environments were used: (i) black shading screen on the sides and roof; and, (ii) black shading screen on the sides and thermal-reflective aluminized screen on the roof. In each environment the following substrates formulated with cattle manure (M) and v

28. Impacto do uso de resíduo de vermiculita no estado endurecido de argamassas
Resumo No processo de beneficiamento da vermiculita é gerado um resíduo fino para o qual atualmente ainda não foi desenvolvida uma aplicação que possibilite a utilização em larga escala. Uma alternativa que vem sendo estudada é a associação com cimento Portland em composições de argamassas e concretos, em função da composição química do res�

29. Mineralogy, Micromorphology, and Genesis of Soils with Varying Drainage Along a Hillslope on Granitic Rocks of the Atlantic Forest Biome, Brazil
ABSTRACT Although the physical environment of the Atlantic Forest realm is well known, studies on the soil-landform relationships are fundamental to improve the management of soil resources to facilitate sustainable development. The purpose of this study was to evaluate a representative topossequence on the “Mares de Morros” landscape of deeply weathered

30. Seed Analysis and Seedling Production of Matayba elaeagnoides Radlk
ABSTRACT The objective of this study was to evaluate the germination potential of Matayba elaeagnoides seeds, identifying the best substrate for laboratory analysis and to determine seedling emergence and growth under different shade levels in the nursery. Different substrates (paper roll, between and on blotting paper, and on sand or vermiculite) were eval

31. PROTECTED ENVIRONMENTS AND SUBSTRATES FOR ACHACHAIRU SEEDLINGS
ABSTRACT The Achachairu (Garcinia humilis) is a Bolivian exotic fruit that has been produced and commercialized a few years in Brazil. Information about the production of high quality seedlings is essential for the implementation and the renewal of orchards. The objective was to evaluate protected environments and substrates for Achachairu seedlings. Two pro

32. Functionalization of Bentonite and Vermiculite after the Creation of Structural Defects through an Acid Leaching Process
The synthesis and use of functionalized materials is growing every year. Thus, this work presents a methodology for the functionalization of bentonite and vermiculite after the acid leaching of the raw materials. Leaching was performed with sulfuric acid (H2SO4), and the functionalization was performed with (3-mercaptopropyl)trimethoxysilane (MPTS), which wa

33. The influence of natural clay and organoclay vermiculite on the formation process of bionanocomposites with poly (3-hydroxybutyrate-co-3-hydroxyvalerate)
ABSTRACT During the last decades, a lot of research work focused on several biodegradable and biosourced polyesters for the purpose of reducing the non-degradable polymer wastes. These polyesters are particularly considered to be promising polymers for biomedical applications and short life-time products like packaging. As these packagings are rapidly discar

34. Hymenaea courbaril SEEDLINGS IN PROTECTED ENVIRONMENTS AND SUBSTRATES
ABSTRACT The Brazilian copal is a tree fruit species that can be used for various purposes. The study evaluated protected environments and substrates in forming Brazilian copal seedlings (Hymenaea courbaril), at the State University of Mato Grosso do Sul, Cassilândia-MS, from January to March, 2014. Two greenhouses were used: (A1) agricultural greenhouse co

35. Experimental Investigation on Self-Compacting Self-Curing Concrete Incorporated with the Light Weight Aggregates
ABSTRACT Self-Compacting Concrete (SCC) flows around obstructions by its self-weight to fill entirely and self-consolidate (without any need for vibration), without any part of disconnection and chunking. The eradication of the need for consolidation leads to better quality concrete and substantial improvement of running conditions. The fresh state of SCC mi

36. PROTECTED ENVIRONMENTS AND SUBSTRATES FOR MANGABEIRA SEEDLINGS (Hancornia Speciosa Gomez) PRODUCTION
ABSTRACT Mangabeira is a native fruit tree from Brazil, which provides a delicious fruit to taste and beneficial to health, whose information about the seedlings production will assist the entire productive chain of this important species. The aim of this research was to evaluate protected environments and substrates compositions in the formation of mangabei
