1. Assessment of coconut fibers for textile applications
ABSTRACT Brazil is the fourth larger producer in coconut fruit in the world. However, the industry processes only a small portion of coconut byproducts, which have caused serious environmental problems. The purpose of this article is to test an alternative for the recovery of coconut byproduct. In a series of experiments, recovered coconut fibers (coir) were

2. Ballistic Application of Coir Fiber Reinforced Epoxy Composite in Multilayered Armor
Multilayered armor systems (MAS) composed of relatively lighter materials with capacity to provide personal ballistic protection are being extensively investigated and used in armor vests. A typical MAS to stand high impact energy 7.62 mm bullet has a front ceramic followed by an aramid fabric laminate, such as Kevlar™. Since both the army and municipal po

3. Coir and Sisal Fibers as Fillers in the Production of Eucalyptus Medium Density Particleboards - MDP
The aim of this study was to evaluate the potential use of sisal and coir fibers in combination with Eucalyptus particles for the production of particleboard. The particleboards were produced in three layers. The first and third layers (face) were made with small Eucalyptus particles. The second layer (core) was made with big Eucalyptus particles in combinat

4. EFECTOS DEL ENRIQUECIMIENTO CON SELENIO EN SPAD, CALIDAD DE LA FRUTA Y PARÁMETROS DE CRECIMIENTO DE PLANTAS DE FRESA EN UN SISTEMA DE CULTIVO SIN SUELO
ABSTRACT Selenium (Se) is an essential trace element for animals, plants, microorganisms and human health. Thus, it appears that increasing amounts of Se in plants could have positive implications. The aim of our study was to evaluate the influence of foliar and substrate application of selenite (Se IV) and selenate (Se VI) on weight, fruit quality, growth

5. Optimization of the production of mycorrhizal inoculum on substrate with organic fertilizer
The system for production of inoculum of arbuscular mycorrhizal fungi (AMF) using sand and vermiculite irrigated with nutrient solution is promising. However, organic amendments added to the substrate can stimulate sporulation of AMF and replace the nutrient solution. The aim of this study was to maximize the production of AMF (Acaulospora longula, Claroideo

6. Viabilidade e autenticação molecular de isolados de Coccidioides spp. da coleção de culturas do Instituto de Medicina Tropical de São Paulo, Brasil
Coccidioidomicose é uma doença emergente no Brasil; a manutenção adequada e autenticação de isolados de Coccidioides spp são essenciais para a pesquisa em diversidade genética de micro-organismos, bem como para a compreensão da doença em humanos. Dezessete isolados de Coccidioides preservados em óleo mineral desde 1975 na coleção de culturas do

7. Production of cellulase by Aspergillus niger under submerged and solid state fermentation using coir waste as a substrate
Aspergillus niger was used for cellulase production in submerged (SmF) and solid state fermentation (SSF). The maximum production of cellulase was obtained after 72 h of incubation in SSF and 96 h in Smf. The CMCase and FPase activities recorded in SSF were 8.89 and 3.56 U per g of dry mycelial bran (DBM), respectively. Where as in Smf the CMase & FPase acti

10. Avaliação de substratos e adubos orgânicos na aclimatização de plântulas de Heliconia psittacorum.
O objetivo deste trabalho foi avaliar a eficiência de três substratos orgânicos - casca de arroz carbonizada, pó de casca de coco seco e verde - e dois adubos -Vitasoloâ e húmus de minhoca -, na aclimatização de plântulas de Heliconia psittacorum L., provenientes da micropropagação. Aos 75 dias, avaliaram-se a altura das plantas, o diâmetro do ps

11. Extrusão de compósitos de PP com fibras curtas de coco : efeito da temperatura e agentes de acoplamento / Extrusion of PP composites with short coir fibers: effect of temperature and coupling agents
Compósitos de PP com fibras curtas de coco foram preparados em extrusora, com dois perfis de temperatura, visando avaliar o efeito compatibilizante de PP modificado com vinilalcoxisilano e com anidrido maleico. Foi verificado que os dois agentes de acoplamento melhoraram o módulo elástico, a tensão máxima e a resistência à absorção de água quando o

12. Tensile Behavior of lignocellulosic reinforced polyester composites: Part III coir fiber
The fiber extracted from the husk of a coconut fruit, known as coir fiber, has been extensively investigated as a second phase incorporation into polymer composites. The moderate strength of the coir fiber usually does not represent reinforcement to relatively strong thermoset matrices such as polyester, epoxy and phenolic. However, a selection of thinner co
