A investigação fitoquímica das raízes de Raulinoa echinata, planta endêmica do Vale do Itajaí/ SC, levou ao isolamento e identificação dos limonóides degradados: fraxinelona, fraxinelonona e epoxi-fraxinelona. O último foi anteriormente isolado dos caules, porém sua configuração relativa não foi resolvida por experimentos de RMN. Este trabalho apresenta a análise de difração de raios-X da epoxi...

OBJECTIVE To compare the interproximal soft tissue dimensions adjacent to single implant restorations in the premolar-molar position with those adjacent to the contra-lateral natural teeth. MATERIAL AND METHODS Twenty-five patients with a single-tooth implant in premolar-molar position and healthy contra-lateral teeth were enrolled in this retrospective cross-sectional study. The reason for t...

Studies carried out in synchronized swimming are very scarce, namely those which include biomechanical analysis of the sculling technique. The purpose of this study was to measure the maximal force produced in standard and contra-standard sculling, using a 30s maximal tethered synchronized swimming test. One former female synchronized swimmer and one former female swimmer performed a 2x30s maxi...

This paper aims to introduce and study fuzzy hypersoft contra open, semi closed, closed maps in topological spaces. Basic properties of are analyzed with examples. Also, the relation between open maps, is discussed. It extended homeomorphism, C-homeomorphism its related characteristics also investigated. The set measure Hamming distance can be applied real-world decision-making problems contain...

This paper presents a numerical study of the acoustic shielding of aeroengine noise by the aircraft structure. More specifically, the engines considered are contra-rotating open rotors in pusher mode which are installed at the rear of the aircraft. Several empennage designs and engine positions are evaluated. An original method for the calculation of engine noise installation effects is present...

Hedonism, or wanting to feel good, is central to human motivation. At times, however, people also seek to maintain or enhance negative affect or to dampen positive affect, and this can be instrumental for the later attainment of their goals. Here, we investigate the assumption that such contra-hedonic orientation is cognitively more demanding than prohedonic orientation, above and beyond the ef...

On March 28, 2016, two patients were evaluated at the Contra Costa Regional Medical Center emergency department (ED) in Contra Costa County, California, for nausea, vomiting, central nervous system depression, and respiratory depression, 30 minutes after ingesting what appeared to be Norco, a prescription opioid pain medication that contains acetaminophen and hydrocodone. The patients purchased...

INTRODUCTION The performance of auditory steady state response (ASSR) in threshold testing when recorded ipsilaterally and contralaterally, as well as at low and high modulation frequencies (MFs), has not been systematically studied. OBJECTIVE To verify the influences of mode of recording (ipsilateral vs. contralateral) and modulation frequency (40Hz vs. 90Hz) on ASSR thresholds. METHODS Fi...

Três complexos inéditos do tipo [Cu(HL)Cl 2 ] foram obtidos com N(4)-orto (H2Bz4oT, HL1), N(4)-meta (H2Bz4mT, HL2) e N(4)-para-toluil-2-benzoilpiridina tiossemicarbazona (H2Bz4pT, HL3), nos quais a tiossemicarbazona coordena-se ao metal por meio do sistema quelante N py N-S. H2Bz4pT (HL3) cristaliza-se no grupo espacial P1 – , a = 9,509(3) Å, b = 9,807(4) Å, c = 11,564(4) Å; α = 100,76(2)°, β =...
