1. Production and Characterization of the Bio-Oil Obtained by the Fast Pyrolysis of Spent Coffee Grounds of the Soluble Coffee Industry
Agro-industrial wastes are abundant and low-cost sources of energy and chemicals. Biomass account for 14% of the world’s energy production. Industrial residues of production of soluble coffee (spent coffee grounds - SCG) have great potential due to its large-scale production and can be transformed by pyrolysis, in liquid, solid and gaseous products with ap

2. Edaphic macrofauna in degradation of animal and vegetable residues
Resumo Este estudo objetivou avaliar a capacidade de degradar a matéria orgânica pela macrofauna edáfica (minhocas), a relação carbono/nitrogênio (C/N) e o potencial hidrogeniônico (pH), durante o processo da vermicompostagem em diferentes resíduos orgânicos. Os tratamentos foram constituídos por resíduos orgânicos de origem animal (esterco bovi

3. The chitinase C gene PsChiC from Pseudomonas sp. and its synergistic effects on larvicidal activity
Pseudomonas sp. strain TXG6-1, a chitinolytic gram-negative bacterium, was isolated from a vegetable field in Taixing city, Jiangsu Province, China. In this study, a Pseudomonas chitinase C gene (PsChiC) was isolated from the chromosomal DNA of this bacterium using a pair of specific primers. The PsChiC gene consisted of an open reading frame of 1443 nucleot

4. Comparative study between poly(ethylene-co-vinyl acetate) - EVA expanded composites filled with banana fiber and wood flour
The objective of this study is to develop expanded composites of poly(ethylene-co-vinyl acetate) (EVA) filled with two vegetable reinforcements (banana fiber or wood flour) as well as to evaluate the influence of the type, size and concentration of these reinforcements on the cell growth and their morphological, mechanical, thermal and physical properties.

5. Soil respiration in cucumber field under crop rotation in solar greenhouse
Crop residues are the primary source of carbon input in the soil carbon pool. Crop rotation can impact the plant biomass returned to the soil, and influence soil respiration. To study the effect of previous crops on soil respiration in cucumber (Cucumis statirus L.) fields in solar greenhouses, soil respiration, plant height, leaf area and yield were measure

6. Forms of sulfur in Brazilian Oxisols under no-tillage system / Formas de enxofre em Latossolos sob sistema plantio direto
Soil is a critical component of the global sulfur (S) cycle acting as source and a sink for various S species and mediating changes of S oxidation states. However, very little is known about the identities of these specific organic and inorganic S containing molecules, especially in Brazilian soils under no-tillage (NT) system. Thus, the objectives of this s

7. Decomposição de resíduos da colheita e transferência de carbono para o solo em plantações de eucalipto / Harvest residue decomposition and carbon transference to the soil in eucalypt plantations
In Brazil, eucalyptus is planted in regions with different climate and soil conditions, which affect harvest residue decomposition and the rate of carbon transference fromresidues (Cres) to the soil, hence influencing soil organic matter (SOM) content. SOM is considered one of the most important indicators of soil quality and forest production sustainability

8. Toxicological evaluation of vegetable oils and biodiesel in soil during the biodegradation process
Vegetable oils and their derivatives, like biodiesel, are used extensively throughout the world, thus posing an environmental risk when disposed. Toxicity testing using test organisms shows how these residues affect ecosystems. Toxicity tests using earthworms (Eisenia foetida. are widespread because they are a practical resource for analyzing terrestrial org

9. Effect of the inclusion of fish residue oils in diets on the fatty acid profile of muscles of males and females lambari (Astyanax altiparanae)
This study evaluated the effects of two lipids sources of fish residue (tilapia and salmon) compared with a vegetable oil source (soybean oil) on the fatty acid profiles of male and female lambari. This experiment was developed in a completely randomized experimental design in a 3 × 2 factorial arrangement, totaling 6 treatments resulting from the combinati

10. Potencial de defensivos biológicos no controle da antracnose e na conservação de bananas na pós-colheita.
RESUMO: Várias doenças acometem a banana na fase de pós colheita , mas a antracnose causada pelo fungo colletotrichum musae ( Berk. & Curtis) Arx. é a de maior expressão econômica. O controle dessa doença vem sendo feiro por imersão dos frutoss em caldas à base de benomil, tiabendazol, tiofanato metílico, prochloraz e imazalil. embora sejam eficaze

11. Síntese e avaliação de sílica tipo M41S contendo cátions CTA em transesterificação catalítica
The investments in the biofuel production have increased a lot in the last years mainly because of smaller damages they cause to the environment in comparison with the derived conventional petroleum fuels. The reaction of biodiesel formation is denominated transesterification and, nowadays that reaction happens in the presence of homogeneous catalyst as the

12. Viabilidade de sementes de papua (brachiaria plantaginea) e a cobertura do solo com palha
O objetivo deste trabalho foi determinar o efeito de palha de aveia preta (Avena strigosa) sobre o solo, na dormência e quiescência de sementes de papuã (Brachiaria plantaginea). Os tratamentos testados foram cobertura do solo (0; 2,6; 5,2; 7,8 e 10,5t/ha), o tempo de permanência das sementes submetidas à ação da cobertura do solo (40, 70, 100, 200 e
