1. EVALUATION OF THE METABOLIC PRODUCTION OF THE ENDOPHYTIC FUNGUS Phomopsis sp.
Endophytic microorganisms have been shown to be an important source of bioactive compounds, and much has been studied about their metabolites. For example, compounds with different biological activities have been isolated from Phomopsis sp. The metabolic study of this genus may lead to a better understanding of the routes of production of metabolites of inte

4. Influence of the methodology on the formation of zeolite membranes MCM-22 for the oil/water emulsion separation
Resumo Esse trabalho teve por objetivo produzir membranas zeolíticas MCM-22 utilizando dois métodos distintos de síntese, dip coating (DC) e transporte em fase vapor (VPT), para serem avaliadas no processo de separação emulsão óleo/água. As membranas foram preparadas a 150 °C por 10 dias, caracterizadas por difração de raios X e microscopia eletr�

5. Shoot proliferation, leaf anatomy and pigment content of Eugenia dysenterica growing in conventional and natural ventilation systems
ABSTRACT Natural ventilation micropropagation systems differ from conventional systems by allowing gas exchange between the internal and external media of the culture flask. The objective of this work was to compare the conventional system of in vitro propagation of Eugenia dysenterica (Mart.) DC. with a natural ventilation system. For shooting, explants wer

6. Influência da compactação do solo sobre a produção e o potencial poluidor de lixiviados de resíduos sólidos urbanos
RESUMO No Brasil, a disposição final de resíduos sólidos urbanos (RSU) representa um risco ambiental em função da geração de lixiviados com altas cargas contaminantes, mesmo em aterros sanitários. Objetivou-se no presente estudo, em escala experimental, avaliar a influência de diferentes graus de compactação do solo (GC) nas camadas intermediári

7. DORMANCY BREAKING, GERMINATION, AND PRODUCTION OF MIMOSA BIMUCRONATA (DC.) KUNTZE SEEDLINGS
ABSTRACT Mimosa bimucronata is a pioneer, easily adapted, fast-growing species used in restoration programs. The objectives of this study were to experimentally compare (1) methods for dormancy breaking; (2) suitable temperature and substrate for germination; and (3) suitable light intensity and substrate volume for seedling production of M. bimucronata. In

8. Seed Quality Evaluation of Senegalia polyphylla (DC.) Britton & Rose
ABSTRACT The aim of this study was to evaluate the quality of Senegalia polyphylla seeds from different trees by X-ray (XR) and electric conductivity (EC) tests. Seeds from three different trees were used. The seeds were classified through radiography in: full, malformed, with small damage and empty, and were used in the germination test. For the EC test, th

9. Antibacterial, chemical and physical properties of sealants with polyhexamethylene guanidine hydrochloride
Abstract The aim of this study was to evaluate the influence of polyhexamethylene guanidine hydrochloride (PHMGH) in the physico-chemical properties and antibacterial activity of an experimental resin sealant. An experimental resin sealant was formulated with 60 wt.% of bisphenol A glycol dimethacrylate and 40 wt.% of triethylene glycol dimethacrylate with a

10. Mechanical-physicochemical properties and biocompatibility of catechin-incorporated adhesive resins
Abstract Several anti-proteolytic dentin therapies are being exhaustively studied in an attempt to reduce dentin bond degradation and improve clinical performance and longevity of adhesive restorations. Objectives This study assessed the effect of epigallocatechin-3-gallate (EGCG) on long-term bond strength when incorporated into adhesives. Material and Me

11. Effect of radiant exposure and UV accelerated aging on physico-chemical and mechanical properties of composite resins
Abstract Currently, there is no consensus in terms of defining the minimum radiant exposure values necessary for achieving adequate properties of composite resin. In addition, the long-term influence that radiant exposure has on the properties of composite resins is still questionable. Objective: The objective of this study was to evaluate the effect of radi
