1. Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables
Abstract Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of carbon dioxide (CO2), which adds to global warming. Thus, aiming to develop an alternative binding s

2. Investigation of ultrasound pretreatment time and microwave power level on drying and rehydration kinetics of green olives
Abstract In this study, the effect of ultrasound (US) combined microwave (MW) drying of green olive slices was studied. Olive samples were exposed to ultrasound (5 and 10 minutes; 32 KHz) at room temperature before dried at microwave at 3 different power level (180W, 450 W and 800 W). The drying and rehydration characteristics and quality parameters of olive

4. STUDENTS BUILDING DIDACTIC EXPERIMENTS AS A TOOL FOR TEACHING UNIT OPERATIONS AND PROCESS CONTROL FOR CHEMISTRY TECHNICIANS
The qualified preparation of technician chemistry students who will act directly in the operation and control of industrial chemical plants is a permanent challenge in the teaching-learning process, since such activities require a broad view of the process and a sum of knowledge’s areas such as unit operations, instrumentation and industrial process contro

5. Convection combined microwave drying affect quality of volatile oil compositions and quantity of curcuminoids of turmeric raw material
Abstract The aim of the work was to estimate the quality of some compositions in turmeric volatile oil and quantity of individual and total curcuminoids in turmeric powder dried under different conditions. Effect of convection time (0–30 min) and microwave time (20–60 min) on quality of volatile oil compositions and quantity of curcuminoids were investig

6. Solar drying of cowpea bean combined with drying in a heat accumulator dryer
RESUMO Como a radiação solar é abundante no Brasil durante quase todo o ano e por ser essa a fonte de energia renovável e não poluente por excelência, a secagem solar dos produtos agrícolas é uma metodologia promissora. Objetivou-se, neste trabalho, secar grãos de feijão-caupi [Vigna unguiculata (L.) Walp.] utilizando energia solar em diferentes te

7. Behaviour of cementitious matrices subjected to the combined action of chloride ions and carbonation
ABSTRACT Carbonation and chloride action are the two leading causes of degradation in reinforced concrete structures. Despite the combined action of these two mechanisms being a reality, there is little research on the effect of this combination in cementitious matrices. Furthermore, the incorporation of fly ash in cementitious matrices has been frequently u

8. Combination of Propylene Glycol Alginate and Lauric Acid on Water Retention and Mechanical Properties of Soy Protein Isolate-Based Films
The water sorption, water barrier properties and mechanical behavior of soy protein isolate (SPI) based films combined with propylene glycol alginate (PGA) and lauric acid (La) via a direct- or co-dried blending process were investigated. Higher water retention ability and a single glass transition temperature (Tg) were found when the PGA was added to form d

9. Salted lamb meat blanket of Petrolina-Pernambuco, Brazil: process and quality
Salted lamb meat blanket, originated from boning, salting, and drying of whole lamb carcass, was studied aiming at obtaining information that support the search for guarantees of origin for this typical regional product from the city of Petrolina-Pernambuco-Brazil. Data from three processing units were obtained, where it was observed the use of a traditional

10. Obtenção de chips de berinjela (Solanun melongena L.) mediante processo combinado de desidratação osmótica em solução ternária e secagem convectiva
This work aimed to utilize the combined osmotic dehydration and convective drying process to obtain eggplant chips by a non-conventional healthier and more low cost way. The combined process was studied through a factorial experimental design having as independent variables the temperature (30-50C), sucrose (27,5 to 42,5% w/w) and sodium chloride (3,75 to 6,

11. Numerical solution of coupled mass and energy balances during osmotic microwave dehydration
The mass and energy transfer during osmotic microwave drying (OD-MWD) process was studied theoretically by modeling and numerical simulation. With the aim to describe the transport phenomena that occurs during the combined dehydration process, the mass and energy microscopic balances were solved. An osmotic-diffusional model was used for osmotic dehydration

12. Multicomponent complex formation between pyrimethamine, cyclodextrins and water-soluble polymers
The combined effect of hydroxypropyl-β-cyclodextrin (HPβCD) and polyvinylpyrrolidone (PVP) or sodium carboxymethylcellulose (CMC) on the solubility of pyrimethamine (PYR) was studied. Equimolar PYR-HPβCD solid systems, in the presence or the absence of 0.25% (w/v) PVP or 0.10% (w/v) CMC were prepared by coevaporation or freeze-drying, and characterized by
