13. Processing of Copper Based Foil Hardened with Zirconia by Non-Deformation Method
Flat sintered copper and copper-zirconia substrates, with zirconia nanoparticles contents of 1 and 3 vol%, were produced by aqueous tape casting and controlled sintering. Aqueous suspensions were prepared to a solid content of 58 vol% using 3 wt% commercial binder emulsion. The green tapes were treated at 350 ºC in air to remove organics and sintered at tem

14. Respiration rate and ethylene metabolism of ‘Jonagold’ apple and ‘Conference’ pear under regular air and controlled atmosphere
ABSTRACT The 1-aminocyclopropane-1-carboxylate (ACC) oxidase activity, ethylene production, CO2 release and O2 uptake of ‘Jonagold’ apple and ‘Conference’ pear were investigated during regular air and controlled atmosphere storage. Storage conditions tested at 0 °C during 6 months, with a further 10 d shelf-life in air at 20 °C were: 0.5 kPa O2 + 6

15. Multivariate analysis of mineral content associated with flesh browning disorder in ‘Fuji’ apples produced in Southern Brazil
ABSTRACT Flesh browning is a physiological disorder that occurs in ‘Fuji’ apples during storage, which causes considerable postharvest losses of fruit produced in Southern Brazil. This work aimed to assess the mineral attributes [Ca; Mg and K contents and the Mg/Ca; K/Ca and (K + Mg)/Ca ratios] associated with the flesh browning disorder incidence, as we

16. Study of Aramid Fiber/Polychloroprene Recycling Process by Thermal Degradation
ABSTRACT Aramid fiber is an important polymer applied as reinforcement in high-performance composites, which, due its exceptional properties, becomes an excellent impact absorption material. It has been broadly utilized in aeronautic industry and ballistic protection. In aircrafts, it is mainly used in secondary structures, such as fairings, floor panels, an

17. Storability of ‘Tupy’ and ‘Guarani’ blackberries in controlled atmosphere
ABSTRACT The aim of this work was to compare the storage potential of ‘Guarani’ and ‘Tupy’ blackberries in controlled atmosphere (CA) and thereafter to determinate the best CA storage conditions for ‘Tupy’ blackberries. Two experiments were carried out. In the first one, ‘Guarani’ and ‘Tupy’ blackberries were stored in CA condition (10 kP

18. Controlled atmosphere maintains native and cultivated yerba mate quality during shelf life after long-term storage
ABSTRACT Yerba mate shows social and economic importance for the Southern Latin American countries due to its easy production and large market range. However, there is a problem to harvest the yerba mate at the correct period and to store it until processing and marketing. Thus, the aim of this paper was to evaluate the interaction among the storage in contr

19. Ethanol reduces ripening of 'Royal Gala' apples stored in controlled atmosphere
O objetivo deste trabalho foi avaliar o efeito do etanol ou aplicação de aldeído acético na manutenção da qualidade pós-colheita de maçãs 'Royal Gala', e compará-los a técnicas de armazenamento consolidadas. Assim, dois experimentos foram realizados durante os anos de 2008 e 2009. No primeiro experimento (2008), foi testada a aplicação de etanol

20. Effect of growth regulators application on the quality maintenance of 'Brookfield' apples
AbstractThe main goal of the present study was to elucidate the effect of growth regulators at harvest and postharvest quality of 'Brookfield' apples stored under controlled atmosphere through a multivariate approach. Thus, an experiment with two steps (field and storage) was carried out. The treatments in field were applied with an output of 1,000 L ha–1

21. Forced-air, vacuum, and hydro precooling of cauliflower (Brassica oleracea L. var. botrytis cv. Freemont): Part II. Determination of quality parameters during storage
Cauliflower heads, which were precooled using four different methods including vacuum, forced-air, and high and low flow hydro precooling, were stored under controlled atmosphere and room conditions. Controlled atmosphere conditions (CA) were as follows: 1°C temperature, 90 ± 5% relative humidity, and 0:21 [(%CO2:%O2) – (0:21) control] atmosphere composi

22. Respiratory quotient: innovative method for monitoring ‘Royal Gala’ apple storage in a dynamic controlled atmosphere
Apples (Malus domestica, Borkh.) which are not stored at low temperature or in a properly controlled atmosphere (CA) may have a high metabolic rate during the postharvest stage resulting in losses in quality. The aim of this study was to evaluate the quality of ‘Royal Gala’ apple fruit stored in accordance with a new method of dynamic controlled atmosphe

23. Respiration rate of Golden papaya stored under refrigeration and with different controlled atmospheres
Knowledge of the respiration rate during the storage is important in the evaluation of the post-harvest tools that preserve fruit quality, and also for the provision of information for the development of new packages. This work aimed to evaluate the respiration rate of 'Golden' Carica papaya stored under refrigeration and controlled atmosphere conditions. Th
