25. Constrictotermes cyphergaster (Blattaria, Termitidae) termite nests as substrates for lichen fixation in the semiarid region of northeastern Brazil
RESUMO Sementes de sabiá (Mimosa caesalpiniifolia Benth.) apresentam dormência tegumentar, dificultando a absorção de água e oxigênio, consequentemente retardando a germinação. Dessa forma, objetivou-se avaliar métodos para superação de dormência associados ao condicionamento fisiológico sobre germinação e vigor de sementes de sabiá, consider

30. Application of Mixture Design Using Diluted Acid for Extraction of Inorganic Components in Fruits of Casearia fasciculata and Determination by ICP OES: Evaluation by PCA and HCA
This study is the first to propose the simultaneous quantification of 10 elements in fruits of Casearia fasciculata by inductively coupled plasma optical emission spectrometry (ICP OES). A method of digestion using dilute nitric acid was optimized by mixture design for extraction of elements in the seed, peel, and pulp of Casearia fasciculata cultivated in t

31. Elevated leptin levels in healthy climacteric women from Northeastern Brazil: an effect of age or adiposity?
ABSTRACT Objective Climacterium is associated with elevated leptin levels and increased risk of cardiovascular disorders. Conflicting data diverge on whether high leptin levels in climacterium reflect increasing adipose mass or, at least partially, age-related hormonal changes. This study addresses this issue in women from a Brazilian state with a low huma

32. MATHEMATICAL MODELING FOR DETERMINATION OF THE MAXIMUM MASS TRANSFER CAPACITY OF COWPEA BEANS
ABSTRACT Cowpea beans are of great socioeconomic expression for the rural population in North and Northeastern Brazil. This legume is rich in essential nutrients and exhibits great resistance to water stress. However, for grain processing, it is fundamental to study legume behavior during the hydration process. This study aims to evaluate the mass transfer o

33. Geochemical Investigation of Tar Balls Collected in a Brazilian Beach Using Biomarkers, Ni/V, δ13C Ratios and Ultra-High Resolution FT-ICR Mass Spectrometry
Representative tar balls collected in two distinct years (2012 and 2014) in a beach along the State of Bahia, northeastern Brazil, were geochemically characterized in order to identify correlations between them and investigate potential sources. Terpanes and steranes biomarkers (detected by gas chromatography coupled to mass spectrometry, GC-MS), carbon stab
