2. Different Types of Lignocellulosic Materials for Energy Generation in the Ceramic Industry
ABSTRACT This work aims at the physicochemical characterization of four species: Eucalyptus sp, Pinus sp, Citrus sinensis and Hevea brasiliensis for use in ceramic furnace. Immediate analysis, chemical analyses were carried out (total extractives, Klason lignin, holocellulose and alpha-cellulose content). Results were applied to ANOVA and Tukey for statistic

3. SYNTHESIS OF MORPHOLINE-BASED IONIC LIQUIDS FOR EXTRACTIVE DESULFURIZATION OF DIESEL FUEL
Abstract Extractive desulfurization with ionic liquids has attracted significant attention from a growing number of scientists due to the current environmental restrictions on fuel. Protic ionic liquids (PILs) were synthesized via equimolar neutralization of morpholine and formic-based compounds. The obtained PILs were characterized by Fourier transform infr

4. Can socioeconomic factors explain the local importance of culturally salient plants in a social-ecological system?
ABSTRACT The aim of this work was to determine whether socioeconomic factors explain the importance of culturally salient plants to social-ecological systems. Extractive communities of the Araripe-Apodi Environmental Protection Area in Northeast Brazil were studied, and a random sample of the population was selected. Quantitative variables (education, age an

6. THERMAL PROFILE OF WOOD SPECIES FROM THE BRAZILIAN SEMI-ARID REGION SUBMITTED TO PYROLYSIS
ABSTRACT The objective of this study was to evaluate the thermal decomposition profile of 10 wood species from the semi-arid region of Brazil using thermogravimetric analysis (TGA) to investigate their potential as biomass energy sources. First, flash carbonization was carried out in a muffle furnace, in which wood samples were heated to a maximum temperatur

7. Density, abundance and extractive potential of the mangrove crab, Ucides cordatus (Linnaeus, 1763) (Brachyura, Ocypodidae): subsidies for fishery management
ABSTRACT Ucides cordatus is a relevant fishery resource of Brazilian mangroves and requires legal normative to sustainable use based on stock assessment and management. This study evaluated some population parameters (structure, density, abundance, fishery potential and stock) of this crab species in Brazil Southeast (São Paulo, State), discussing the use o

8. Aproveitamento gastronômico de pescados oceânicos de ocorrência local em cardápios de restaurantes no litoral de Santa Catarina
Santa Catarina is one of the Brazilian states with high fish production. There are 139 cataloged fish species caught off the coast by the artisanal and industrial fisheries. The fish species most frequently caught are sardine (Sardinella brasiliensis), skipjack tuna (Katsuwonus pelamis) and whitemouth croaker (Micropogonias furnieri). This study analyzes the

9. CONSERVAÇÃO VERSUS CONFLITOS SOCIOAMBIENTAIS (COMUNIDADE JATOBÁ) NO FUTURO PARQUE ESTADUAL DAS DUNAS: Barra dos Coqueiros, Sergipe. / SOCIAL AND ENVIRONMENTAL CONSERVATION VERSUS CONFLICT (COMMUNITY JATOBÁ) THE FUTURE OF DUNES STATE PARK: Barra dos Coqueiros, Sergipe.
The conservation of the biodiversity of the dunes hás raised social interest and as a measure already politicized in the State, the environmental institutions have positioned themselves in defense of the creation in the future of the Parque Estadual das Dunas. There are two issues around the creation of a Unity of Whole Protection in the area: the first one

12. Implantação da piscicultura familiar com pescadores e agricultores assentados no Município de Lucena-PB
Fishing is a very important activity for the provision of protein, but as a result of the heavy pressure from extractive fishing and above the limits of carrying capacity of populations of commercial species, many stocks are at or above the limit of exploration, which has resulted in decreased populations of many animals, including driving some to extinction
