1. Agroindustry Residues as a Source for Cellulose Nanofibers Production
Our study was motivated by the large amount of crop residues produced in Brazil, which represent underutilized waste biomass and a serious threat to the environment because of the landfilling. For example, even though the corn crop is not popular in Brazil, it is produced in the area of around 18-20 million hectares with an average production of 5-6 t ha-1.

2. Evaluation of the Metabolic Profile of Arabica Coffee via NMR in Relation to the Time and Temperature of the Roasting Procedure
Coffee is one of the most popular and consumed products in the world, with high nutritional value and economic importance. However, some factors can change the organoleptic properties of a coffee species, without causing significant damage such as loss of important components. The present study evaluated the chemical profile, via nuclear magnetic resonance (

3. Quality of pasta made of cassava, peach palm and golden linseed flours
Abstract The possibility of industrially producing new types of pastas based on other types of flour than wheat has raised interest for enabling the use of widely available materials and providing adequate products to persons with celiac disease. A mixture design was developed with the purpose of preparing a gluten-free dry using cassava starch, peach palm m

4. Best videos of the year for 2019
The aims of the current study are to investigate the composition of biomass from baru processing and to explore the feasibility of valuing it through the development of bioproducts such as fermentable sugars, furanics and biochar. Baru (Dipteryx alata Vog.) waste (endocarp and mesocarp) has great energetic potential to produce bioproducts due to its chemical

6. Concomitant Production of Hydrogen, Sodium Acetate, and Polymerized Species from Non-Catalytic Ethanol Dehydrogenation
A detailed study of the production of hydrogen and high added-value liquid products from the ethanol dehydrogenation reaction in the presence of sodium hydroxide (10% m m-1) was undertaken. Experiments were carried out in a batch reactor under different reaction conditions (temperature of 240 ºC and autogenous pressure between 45 and 72 bar), with analysis

8. Adding value to polystyrene waste by chemically transforming it into sulfonated polystyrene
ABSTRACT Polystyrene (PS), one of the most used polymers in everyday life, has a low recycling rate due to its inexpensive virgin resin. In order to make polystyrene waste (WPS) recycling advantageous, it is possible to change it chemically, introducing heteroatoms in the polymer chain thus transforming the waste into a material with more added value. In thi

10. An Inter-Semiotic Study of Ideology on the Book Covers of Persian Translations of George Orwell’s Animal Farm
Abstract All the movements and revolutions in the world’s history have been initiated and reinforced by a systematized structure of standards, opinions and thoughts establishing the foundations of political, social or economic perspectives known as ideology. Ideology plays a vital role when the dimension of translation is added to the argument, for in addi

12. Bamboo particleboards: recent developments
RESUMO Devido à grande variação dimensional do bambu, a produção de materiais como compensados e laminados produz grande quantidade de resíduos. A produção de painéis particulados poderia ser utilizada para superar este problema e tornar-se uma solução viável na reutilização dos resíduos gerados como matéria-prima para produtos de alto valor
