1. Iron Nitrate Modified Cotton and Polyester Textile Fabric Applied for Reactive Dye Removal from Water Solution
In this work, we investigated the use of cotton scraps in natura and modified with iron nitrate, in the adsorption of one of the main water contaminants of the textile industries, the reactive black dye. Special attention was paid to the appropriate destination of the spent adsorbent, in compliance with the precepts of the circular economy. Cotton and polyes

4. Plasma Treatment of Polyamide Fabric Surface by Hybrid Corona-Dielectric Barrier Discharge: Material Characterization and Dyeing/Washing Processes
In this study, the hybrid corona-dielectric barrier discharge plasma treatment was employed to modify the physical, chemical and morphological characteristics of a half-knitted fabric composed of 92% polyamide 6.6 and 8% elastane (PA). These properties of the fabric were evaluated by the water contact angle, x-ray diffraction, infrared spectroscopy, scanning

6. Evaluation of the Projectile's loss of Energy in Polyester Composite Reinforced with Fique Fiber and Fabric
Firearms threat has always been a matter of personal concern, especially to soldiers in armed conflicts as well as police officers and civilians involved with public security. A multilayered armor system (MAS) is intended to personal protection against high kinetic energy ammunition, such as that used in rifles. MAS layers are normally composed of a front ce

7. Evaluation of Dynamic Mechanical Properties of Fique Fabric/Epoxy Composites
The fique is a plant typical of the Colombian Andes, from which relatively common items are fabricated. One of these is woven fabric extensively applied in sackcloths. The mechanical strength of fique fabric have motivated recent investigations on possible reinforcement of polymer matrix composites. For this purpose its thermo-mechanical behavior was unveile

8. Sobrevivência e viabilidade de escleródios de Botrytis squamosa no solo
RESUMO Em experimento de campo quantificou-se a sobrevivência e a viabilidade de escleródios de Botrytis squamosa no solo. Cem escleródios multiplicados pela técnica de esfregaço de micélio em meio de cultura BDA foram colocados em saquinhos feito de tecido voal. Em armação de madeira contendo solo, colocaram-se 12 repetições respectivamente na sup

9. Construindo histórias em tessitura lenta: desinstitucionalização e narrativas em pesquisa
Resumo As críticas ao modelo manicomial fazem frente não só à existência do hospital psiquiátrico como também, no caso da desinstitucionalização, às estruturas e lugares de poder que corroboram a desimplicação na vida e na própria dignidade do sujeito. Nesse sentido, estudos sobre os desafios do cuidado em liberdade e a produção de conheciment

10. Impact of methods used to reconstitute tailings specimens on the liquefaction potential assessment of tailings dams
Abstract The aim of this research is to investigate the liquefaction susceptibility of silt sandy mining tailings by experimental laboratory techniques. The main aspect analyzed is how techniques of sample reconstitution impact the results obtained in static undrained triaxial tests. Different methods of sample preparation are reviewed, such as moist tamping
