3. Safflower root and shoot growth affected by soil compaction
ABSTRACT Safflower (Carthamus tinctorius L.) is a commercial seed crop grown for its good yield of high-quality oil. It is tolerant to water stress but may be sensitive to soil compaction. The aim of this study was to assess safflower growth under different degrees of soil compaction at depths of 0.15 m to 0.20 m. The experiment was carried out in PVC pots c

4. Microencapsulation of grape seed oil by spray drying
Abstract In the search for alternative wall materials to replace gum Arabic (GA), a good but expensive encapsulating agent, this work aimed to evaluate the effectiveness of maltodextrin 10DE in combination with GA (GA/MD, 50:50 ratio) for the microencapsulation of grape seed oil by spray drying. The addition of maltodextrin to gum Arabic did not influence t

5. Hybrid Sandwich Particleboard Made with Sugarcane, Pínus Taeda Thermally Treated and Malva Fibre from Amazon
A multilayer particleboard panels, consisted of sugarcane bagasse reinforced composite as core material and hybrid composites made with Pinus taeda particles and Malva fibres as facing materials, were designed and evaluated in this work. Tukey test was used to identify the effect of the facing material, considering different combinations of Pinus taeda parti

6. Least limiting water range for oil palm production in Amazon region, Brazil
ABSTRACT In areas cultivated with oil palm, typically mechanized field operations using heavy vehicles may negatively affect soil physical properties and productivity. The aim of this study was to evaluate soil physical quality in an area cultivated with oil palm by monitoring the temporal variation of the soil water content and relating it to the critical l

7. Cassava processing wastewater as a platform for third generation biodiesel production
ABSTRACT This study aimed to evaluate third generation biodiesel production by microalgae Phormidium autumnale using cassava processing wastewater as a platform. Experiments were performed in a heterotrophic bubble column bioreactor. The study focused on the evaluation of the bioreactor (batch and fed-batch) of different operational modes and the analysis of

8. Microencapsulation of babassu coconut milk
The objective of this study was to obtain babassu coconut milk powder microencapsulated by spray drying process using gum Arabic as wall material. Coconut milk was extracted by babassu peeling, grinding (with two parts of water), and vacuum filtration. The milk was pasteurized at 85 ºC for 15 minutes and homogenized to break up the fat globules, rendering t

9. Aplicação de técnicas fatoriais de planejamento no desenvolvimento de um modelo de avaliação da oxidação em óleos e emulsões / Application of factorial design techniques on the development of an assessment model of the oxidation in bulk oils and emulsions
A estabilidade oxidativa em óleos e emulsões é influenciada pela ação simultânea de diversos fatores. Entretanto, a avaliação do efeito antioxidante de novos compostos tem sido conduzida utilizando-se valores fixos para esses fatores. Portanto, o objetivo deste estudo foi aplicar técnicas fatoriais para desenvolver modelos de oxidação lipídica no

10. Estudo da corrosão de aço AISI 1020 em meio de petróleo / Study of corrosion of AISI 1020 steel in crude oil
A agressão química do petróleo, o qual contém compostos corrosivos tais como H2S, CO2, ácidos naftênicos e sais dissolvidos em fase aquosa, combinada com efeitos de variação do pH, temperatura, fluxo e pressão, tem grande influência na taxa de corrosão em equipamentos de aço. Devido a pouca quantidade de trabalhos encontrados na literatura relaci

11. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

12. Síntesis de espumas rígidas de poliuretano obtenidas a partir de aceite de castor y poliglicerol empleando calentamiento por microondas
In this work we showed the polyurethane rigid foams synthesis using a macropolyol synthesized from castor oil and polyglycerol. This process is optimized employing a response surface analysis and using a 3² factorial design. The factors evaluated were: amount of water and tartaric acid, where tartaric acid acts as crosslinking agent and catalyst; mechanical
