13. Development, characterization and stability of microemulsionated formulations of bacaba, Oenocarpus bacaba oil
RESUMO Os avanços no âmbito da nanotecnologia, aliados ao uso de produtos naturais, representam uma área promissora de pesquisa. O Brasil é um país de rica biodiversidade, especialmente na floresta amazônica. Frutos utilizados comumente nas comunidades locais, como a bacaba (Oenocarpus bacaba), são potencialmente interessantes para prospecção de apl

14. Numerical experiments with the Generalized Finite Element Method based on a flat-top Partition of Unity
Abstract The Stable Generalized Finite Element Method (SGFEM) is essentially an improved version of the Generalized Finite Element Method (GFEM). Besides of retaining the good flexibility for constructing local enriched approximations, the SGFEM has the advantage of presenting much better conditioning than that of the conventional GFEM. Actually, bad conditi

15. Rectoría y gobernanza: dimensiones estructurantes para la implementación de Políticas de Atención Primaria de Salud en el Paraguay, 2008-2017
Abstract This study analyzes the conduction patterns of implementing Primary Health Care (PHC) in Paraguay in three government periods (2008-2012, 2012-2013 and 2013-2017) and three management levels (national, regional and local). This is a qualitative study based on grounded theory. A priori categories on PHC stewardship and governance in Paraguay were ana

16. Aging simulation of the tailings from Stava fluorite extraction by exposure to gamma rays
Abstract Tailings storage facilities are disposal systems for storing the waste products of the mining industry consisting of a slurry mixture made of soil, rock and water that remain after the mineral values have been removed from the patent ore. Tailings dams are supposed to last forever, so after their deposition, tailings can experience aging processes w

17. Sugars levels of four sugarcane genotypes in different stem portions during the maturation phase
ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure bett

18. High fire temperature changes soil aggregate stability in slash-and-burn agricultural systems
ABSTRACT Fire is a key controlling factor in ecosystem dynamics worldwide, especially, in tropical areas under slash-and-burn agricultural systems. Farmers use fire as a tool to clean the land, and benefit from nutrient enrichment from ash-soil heating. However, fire can cause some detrimental effects on soil systems, such as organic carbon depletion, increa

19. A Backtracking Search Algorithm for the Simultaneous Size, Shape and Topology Optimization of Trusses
Abstract This paper presents a Backtracking Search Optimization algorithm (BSA) to simultaneously optimize the size, shape and topology of truss structures. It focuses on the optimization of these three aspects since it is well known that the most effective scheme of truss optimization is achieved when they are simultaneously considered. The minimization of

20. AVALIAÇÃO DA EFICIÊNCIA DO MÉTODO TO-15 PARA DETERMINAÇÃO DE COMPOSTOS ORGÂNICOS VOLÁTEIS EM CONDIÇÕES TÍPICAS DE AMBIENTE URBANO
The efficiency of U.S.EPA TO-15 Method was evaluated under typical conditions of an urban environment with natural and anthropic emission sources. The performance criteria which should be met for a system to qualify, were fulfilled: a detection limit of ≤0.2 ng for all target compounds, replicate precision for a calibration standard and ambient samples wit

21. Formation Flight Control of Multi-UAV System with Communication Constraints
ABSTRACT Three dimensional formation control problem of multi-UAV system with communication constraints of non-uniform time delays and jointly-connected topologies is investigated. No explicit leader exists in the formation team, and, therefore, a consensus-based distributed formation control protocol which requires only the local neighbor-toneighbor informa

22. Poly(vinyl alcohol)-hyaluronic Acid Membranes for Wound Dressing Applications: Synthesis and
in vitro Bio-EvaluationsPhysically crosslinked poly(vinyl alcohol)-hyaluronic acid (PVA-HA) hydrogel membranes composed of different amounts of HA were prepared by freeze-thawing (F-T) method. F-T cycle was repeated for three consecutive cycles. HA was chosen and routinely utilized in the local treatment of chronic wounds, because of its advantages as, HA is endogenous and biode

23. Characterization of Bacteriocin like inhibitory substance produced by a new Strain Brevibacillus borstelensis AG1 Isolated from 'Marcha'
In the present study, a bacterium isolated from Marcha- a herbal cake used as traditional starter culture to ferment local wine in North East India, was evaluated for bacteriocin like inhibitory substance production and was tested against six food borne/spoilage causing pathogens viz. Listeria monocytogenes MTCC 839, Bacillus subtilis MTCC 121, Clostridium p
