17. High Throughput Mass Spectrometry Platform for Prospecting High Value Chemicals from Bioconversion of Glycerin
The use of bioprocess to convert low valued biomass or agroindustrial byproducts into high-value chemicals is an emerging area. However, laboratories usually use outdated analytical techniques to identify bioproducts, losing valuable information, such as the identification of unexpected compounds. In this work, we presented a successful systematic and modern

18. Evaluation of yeast culture and direct-fed microbial on gut histology and serum components of broilers challenged with suboptimal diets under heat stress
ABSTRACT. The use of antibiotics in feed for growth promotion has been restricted in many countries, thus it is of interest to investigate potential alternatives for enhancing growth performance in birds. An experiment was carried out to evaluate the concurrent use of prebiotic and probiotic on gut histology and some blood chemicals of broiler chickens dur

19. Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae)
Abstract Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras

20. EFFECT OF ALUMINUM SULFATE AND CATIONIC POLYMER ADDITION IN THE MIXED LIQUOR OF A SUBMERGED MEMBRANE BIOREACTOR (SMBR): SLUDGE CHARACTERISTICS AND ORTHOPHOSPHATE REMOVAL IN BATCH EXPERIMENTS
Abstract Submerged Membranes Bioreactors (SMBR) are an established technology for wastewater treatment for water recovery and reuse. However, its routine application is still compromised by the high energy consumption to overcome the fouling effect. This study evaluated the effect of aluminum sulfate and cationic polymer in the orthophosphate removal and slu

21. THERMAL MODIFICATION OF SUGARCANE WASTE AND BAMBOO PARTICLES FOR THE MANUFACTURE OF PARTICLEBOARDS
RESUMO A modificação térmica de partículas de painéis constituídos de resíduos agroflorestais e industriais pode incorporar melhorias na estabilidade dimensional (variação na espessura) e reduzir a utilização de produtos químicos, que podem onerar o processo ou serem nocivos ao homem e ao meio ambiente. Assim, o objetivo da pesquisa foi avaliar o

23. Influência da manta geotêxtil e altura da camada de lodo no desaguamento de lodo anaeróbio em leito de drenagem
RESUMO As estações de tratamento de esgoto (ETEs) geram resíduos, com destaque para o lodo de esgoto, que tem aproximadamente 95% de água e se classifica como resíduo sólido, necessitando de disposição final ambientalmente adequada. Assim, o desaguamento é fundamental no gerenciamento do lodo, já que promove redução de volume. O leito de drenagem
