1. Easily applicable protocol to formulate inks for extrusion-based 3D printing
Abstract 3D printing is a disruptive technology that is a key driver of the new industrial revolution. Among the various 3D printing methods, direct-ink-writing (DIW) takes a viscous ink material, extrudes it through a nozzle, and deposits it layer-by-layer to create 3D objects. DIW is a versatile method that can print ceramics, polymers, metals, living cell

2. Lignin-modified road marking paint: weathering aging studies
Abstract The accelerated artificial aging with ultraviolet radiation, viscosity, density, no-pick-up time, flexibility, and abrasion resistance of lignin-modified road marking paint were evaluated. The addition of lignin did not cause significant changes in the physical chemistry, flexibility and no-pick-time test compared to the precursor paint. The additio

3. The influence of cultivar and enzyme treatment on the aroma complex of apple juice
Abstract This paper aims to determine the influence of a cultivar (Golden delicious and Granny Smith) and enzyme treatments (hot and cold) on the aroma complex of clear apple juice. While the composition of aromatic components of the juice was determined by Gas Chromatography Mass Spectrometry (GC/MS) technique, a panel of 24 semi trained evaluators carried

4. Effects of sintering temperature on microstructure and properties of sanitaryware ceramic produced with waste material
Abstract This paper aims at exploring the possibility of using a great percentage of recycled materials into vitreous china (VC), thus, contributing to urban waste decrease while lowering the industry’s buying costs, previously optimized, for the sanitaryware production. The recycled blend was introduced in the ceramic slip, Sanitser VC, and used in three

6. Evaluation of Lignins of Trunk and Roots from Citrus sinensis L. Osbeck: A Large Available Brazilian Biomass
Citrus biomass is a source of biobased products and presents extensive chemical diversity. Among the structural macromolecules, lignins have been used in resins, bioplastics, and nanoencapsulation. Brazil has a large source of lignins, which are orange trees removed from groves that need to be renewed. However, the knowledge about these lignins is limited an

7. On the possibility of obtaining high-quality lyophilized collagen hydrolysate and its applicability in the sausage production
Abstract The paper discusses the issues of rational use of secondary collagen-containing raw material in the food industry, namely cattle by-products. The technology of obtaining collagen hydrolysate from this type of raw material with the subsequent freeze-drying is proposed, which maximizes the level of preservation of native properties and the expands the

8. A MULTIPLE CRITERIA ANALYSIS OF FACTORS INFLUENCING SURFACE ROUGHNESS OF WOOD AND WOOD-BASED MATERIALS IN THE PLANING PROCESS
ABSTRACT This paper presents a study of the fuzzy analytical hierarchy process (FAHP) for the prioritization of factors having important effects on the surface roughness of wood and wood-based materials in the planing process. Firstly, a three-level hierarchical model was devised. Secondly, the FAHP method was employed to determine the weights of the factor

9. Characterizing the Chemical Composition of Lipophilic Extracts from Acacia mearnsii Wood
The chemical composition of Acacia mearnsii wood extract is described in this paper for the first time. This wood is cultivated in Brazil and has been used to complement the demand for hardwood in the pulp industry. In this study, we performed extractions with acetone (total extracts) and dichloromethane (lipophilic extracts responsible for the pitch formati

11. Evidências da importância da indústria e dos serviços para o crescimento econômico dos municípios brasileiros
Resumo A literatura baseada em Kaldor defende a indústria como o motor do crescimento econômico (engine of growth hypothesis). Contudo, trabalhos recentes destacam a relevância dos serviços para impulsionar o crescimento. Contribuindo para tal debate, o objetivo deste estudo é avaliar os efeitos das participações dos setores industrial e de serviços

12. A METHODOLOGY TO OBTAIN ANALYTICAL MODELS THAT REDUCE THE COMPUTATIONAL COMPLEXITY FACED IN REAL TIME IMPLEMENTATION OF NMPC CONTROLLERS
Abstract Model Predictive Control, MPC and NMPC, and real-time optimization, RTO and D-RTO, are known to help plant operability through the mitigation of impacts caused by external disturbances. However, the usage of these tools in industry requires overcoming some challenges, for instance: accurate models of the process, particularly in regard to nonlineari
