1. Study for the incorporation of wood ash in soil-cement brick
Abstract This study aimed to produce soil-cement brick with wood ash incorporation coming from the textile industry. The wood ash was a partial substitute for soil and cement in the manufacture of bricks. 7 formulations were made with different proportions of substitution: 10%, 20%, and 30%. It was noticed that the substitution of cement by wood ash in 10% r

2. Gluten-free pasta: development of a new formulation based on rice and lupine bean flour (Lupinus Mutabilis) using a mixture-process design
Abstract Gluten-free pasta was developed by substituting rice flour (RF) with lupin flour (LF). The factors tested were the substitution of RF by LF (10g/100g -30g/100g), egg (8g/100g -30g/100g) and guar gum (0.15g/100g -1g/100g) using a mixture-process design. Seven response variables were measured. Luminosity, ash content, protein content, chrome, hue, wei

3. Evaluation of the Influence of the Substituting Cation on the Structural and Morphological Properties of the New Garnet Sm3−xREExFe5O12 (REE = Dy, Gd and Lu)
Rare earth garnets (REE3Fe5O12) have magnetic-electric and optical properties that can be used in transmitters, microwave and data storage devices. These properties depend mainly on partial or total substitution of the cationic sites, as well as by the synthesis method used. Therefore, in this work was studied the influence of the substituting cation on the

5. Lightweight high-strength concrete with the use of waste cenosphere as fine aggregate
RESUMO Cenosfera é um sub-produto da combustão do carvão que apresenta interessantes propriedades para ser usado na produção de materiais cimentícios, tais como estrutura oca, baixa densidade, baixa térmica condutividade e notável estabilidade térmica. Além disso, ela mostra reatividade pozolânica na cura térmica. Entretanto, o potencial da cenos

6. Avaliação térmica, física e mecânica de blocos de concreto com poliestireno expandido reciclado
Resumo A presente pesquisa produziu blocos de concretos com substituição parcial do agregado graúdo comumente utilizado por poliestireno expandido reciclado. Para tanto, uma dosagem experimentalé proposta a partir da associação do modelo de empacotamento compressível com a metodologia adaptada de Tango, publicada em 1994, produzindo-se quatro tipos de

7. Partial substitution of fishmeal with soybean protein-based diets for dourado Salminus brasiliensis
ABSTRACT Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salmi

8. Evaluation of mortar properties obtained through partial substitution of Portland cement by ashes of oil palm empty fruit bunch
Resumo Atualmente, o óleo de palma é líder em produção e consumo dentre os óleos comestíveis comercializados, com uma produção mundial que ultrapassa 66 milhões de toneladas anuais. Estima-se que a produção de resíduo da queima do engaço do dendê como combustível nas caldeiras corresponde a 5% em massa do total de óleo extraído. Este trabal

10. Copper slag from different dumps in the Atacama Region used in mortars as partial replacement of cement
ABSTRACT The use of copper slag as a partial substitute for cement in mortar preparation was studied. Copper slag samples were collected from three dumps in the Atacama Region (Northern Chile). Mortars of 40x40x160 mm (width, height, length) and curing times of 7, 28 and 90 days were used in mechanical testing. Tests were performed with 0% (control mortar),

11. Effect of the addition of young bamboo culm flour as a sugar and/or fat substitute in cookie formulations
Abstract One of the innovation strategies of the bakery industry is the use of new ingredients capable of increasing the health appeal of products. The objective of this study was to evaluate the effect of partial substitution (15%) of wheat flour by young bamboo culm flour (YBCF) in cookies formulations, using a central composite design with two variables

12. Reduced-order strategy for meshless solution of plate bending problems with the generalized finite difference method
Abstract This paper presents some recent advances on the numerical solution of the classical Germain-Lagrange equation for plate bending of thin elastic plates. A meshless strategy using the Generalized Finite Difference Method (GFDM) is proposed upon substitution of the original fourth-order differential equation by a system composed of two second-order par
