2. Survival of resistant starch during the processing of atmospheric and vacuum fried instant noodles
Abstract The objective was to develop instant noodles (IN) made by atmospheric and vacuum frying processes, with addition of 10% of three different sources of resistant starch: resistant starch type 2 (RS2), resistant starch type 3 (RS3) and green banana flour (GBF) aiming the increasing of the fibre content. The IN obtained by atmospheric frying lost water

3. Aplicações da celulose de palha de cana-de-açúcar: obtenção de derivados partindo de celulose branqueada e de biocompósitos com poliuretana obtida a partir de óleo de mamona (Ricinus communis L.) / Applications of sugarcane straw cellulose: obtainment of derivatives from bleached cellulose and biocomposites with polyurethane obtained from castor oil (Ricinus communis L.)
The sugarcane processing generates various agricultural byproducts such as bagasse and straw, which is considered one of the main waste generated due to the mechanization of the harvest in Brazil. Thus, the availability and composition of sugarcane straw have driven a great effort to develop technologies that provide its effective utilization. This study aim

4. Avaliação da influência da temperatura e ponto de orvalho no recozimento final de aços elétricos semiprocessados e totalmente processados / Evaluation of the influence of final annealing heat treatment temperature and dew point in semi-processed and fully processed electrical steels
Semi-processed electrical steels require annealing after processing in the motors manufactures to improve motors efficiency by reducing losses and increasing permeability. Annealing in fully processed electrical steel is performed to relax the residual stress and promote recovery or recrystallization of distorted parts. Commercial samples from different stee

6. Evaluation of pre-treatment and application of edible coatings in fruits drying / Avaliação de pre-tratamentos e aplicação de coberturas comestiveis na secagem de frutas
Most vegetables and fruits are highly perishable due to a high water conten, which makes it difficult to trade, since seasonality and distance between markets demand costly refrigerated storage and transportation. Increasing shelf life and availability throughout the year by processing reduces losses by marketing of fresh foods. This research aimed at evalua

9. Hydrothermal alteration of the Cerro La Mina gold prospect, Los Menucos, Patagonia Argentina : geology, remote sensing and stable isotopes / Alteração hidrotermal do prospecto aurifero Cerro La Mina, Los Menucos, Patagonia Argentina : geologia , sensoriamento remoto e isotopos estaveis
The epithermal Cerro La Mina prospect, located in the Los Menucos region, Patagonia Argentina, is currently being explored for epithermal precious-metal mineralization. Triassic hydrothermal activity produced intense alteration of rhyolites, andesites, ignimbrites, and tuffs of the Middle- to Late Triassic Los Menucos Group, in the Somún Curá massif. The u

11. Influence of surface topography on the surface durability of steam oxidised sintered iron
Durability of surfaces has been reported as the main factor affecting tribological behavior of steam oxidised sintered iron. The presence of surface pores and their negative influence on load bearing capacity, suggest that surface topography might play an important role on the durability of the oxide layer. In this paper, the influence of compaction pressure
