Components of Turnera diffusa Willd. var. afrodisiaca (Ward) Urb. essential oil

Turnera diffusa Willd. var. afrodisiaca (Ward) Urb. (syn. T aphrodisiaca) (Turneraceae) is a common aromatic plant growing wild in the subtropical regions of America and Africa. Its essential oil was studied by GC and GC-MS. Fifty-four components were characterized and identified, the most abundant being 1,8-cineol (11.4%), opoplenone (10.3%) cadalene (5.1%) and epi-cubenol (4.1%).

Light-front zero-mode contribution to the Ward Identity

In a covariant gauge we implicitly assume that the Green's function propagates information from one point of the space-time to another, so that the Green's function is responsible for the dynamics of the relativistic particle. In the light front form one would naively expect, that this feature would be preserved. In this manner, the fermionic field propagator can be split into a propagating piece and a non-propagating (contact) term. Since the latter (contact) one does not propagate information; and therefore, supposedly can be discarded with no harm to the field dynamics we wanted to know what would be the impact of dropping it off. To do that, we investigated its role in the Ward identity in the light front. Here we use the terminology Ward identity to identify the limiting case of photon's zero momentum transfer in the vertex from the more general Ward-Takahashi identity with nonzero momentum transfer.

Application of low-pressure gas chromatography-ion-trap mass spectrometry to the analysis of the essential oil of Turnera diffusa (Ward.) Urb.

Turnera diffusa Willd. var. afrodisiaca (Ward) Urb. (syn. T. aphrodisiaca) belongs to the family of Turneraceae and is an aromatic plant growing wild in the subtropical regions of America and Africa. It is widely used in the traditional medicine as e.g. anti-cough, diuretic, and aphrodisiac agent. This work presents a 3 min chromatographic analysis using low-pressure (LP) gas chromatography (GC)-ion-trap (IT) mass spectrometry (MS). The combination of a deactivated 0.6 m x 0.10 mm i.d., restrictor with a wide-bore CP-Wax 52 capillary column (10 m x 0.53 mm i.d., 1 mum) reduces the analysis time by a factor of 3-7 in comparison to the use of a conventional narrow bore column. Chromatographic conditions have been optimized to achieve the fastest separation with the highest signal/noise ratio in MS detection. These results allow fast and reliable quality control of the essential oil to be achieved. (C) 2003 Elsevier B.V. All rights reserved.

Review of Native Americans in the School System: Family, Community, and Academic Achievement by Carol J. Ward

The title of this volume promises more than the content delivers. The heart of the book is information from Ward's 1992 University of Chicago doctoral dissertation, which focused on the social and cultural reasons leading to students dropping out of school. Her first two chapters provide a good review of research on dropouts and Indian education; the following six focus on the results of her 1987-1989 study of 698 Northern Cheyenne, Crow, and white high school students attending the Colstrip Public, St. Labre Catholic, and Busby Tribal Schools in Montana. Fifty-two percent of the students in this study were Indian, with a dropout rate of 45% .

Prevalence of depression and anxiety disorders in hospitalized patients at the dermatology clinical ward of a university hospital

BACKGROUND: The objective of this study was to estimate the prevalence of depression and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo, Brazil. OBJECTIVE: To assess the prevalence of mood and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo. METHOD: A total of 75 patients, men and women, aged between 18 and 76 years, took part in the research. The study employed a descriptive, cross sectional and correlational method. The data was collected by means of a social demographic questionnaire and the PRIME-MD. RESULTS: It was found that 45.3 percent of the subjects presented with depressive symptoms, and 52 percent presented with symptoms of anxiety and that this survey showed moderate and high significant correlations (p<0,01; r= 0,616) for depression and anxiety. CONCLUSION: These facts could evidence the relationship between physical and psyche, just as the literature presents.

Use of recent geoid models to estimate mean dynamic topography and geostrophic currents in South Atlantic and Brazil Malvinas confluence

The use of geoid models to estimate the Mean Dynamic Topography was stimulated with the launching of the GRACE satellite system, since its models present unprecedented precision and space-time resolution. In the present study, besides the DNSC08 mean sea level model, the following geoid models were used with the objective of computing the MDTs: EGM96, EIGEN-5C and EGM2008. In the method adopted, geostrophic currents for the South Atlantic were computed based on the MDTs. In this study it was found that the degree and order of the geoid models affect the determination of TDM and currents directly. The presence of noise in the MDT requires the use of efficient filtering techniques, such as the filter based on Singular Spectrum Analysis, which presents significant advantages in relation to conventional filters. Geostrophic currents resulting from geoid models were compared with the HYCOM hydrodynamic numerical model. In conclusion, results show that MDTs and respective geostrophic currents calculated with EIGEN-5C and EGM2008 models are similar to the results of the numerical model, especially regarding the main large scale features such as boundary currents and the retroflection at the Brazil-Malvinas Confluence.

Ward identities in Lifshitz-like field theories

In this work, we develop a normal product algorithm suitable to the study of anisotropic field theories in flat space, apply it to construct the symmetries generators and describe how their possible anomalies may be found. In particular, we discuss the dilatation anomaly in a scalar model with critical exponent z = 2 in six spatial dimensions.

Effects of neuromuscular electrostimulation in patients with heart failure admitted to ward

Background: Neuromuscular electrostimulation has become a promising issue in cardiovascular rehabilitation. However there are few articles published in the literature regarding neuromuscular electrostimulation in patients with heart failure during hospital stay. Methods: This is a randomized controlled pilot trial that aimed to investigate the effect of neuromuscular electrostimulation in the walked distance by the six-minute walking test in 30 patients admitted to ward for heart failure treatment in a tertiary cardiology hospital. Patients in the intervention group performed a conventional rehabilitation and neuromuscular electrostimulation. Patients underwent 60 minutes of electrostimulation (wave frequency was 20 Hz, pulse duration of 20 us) two times a day for consecutive days until hospital discharge. Results: The walked distance in the six-minute walking test improved 75% in the electrostimulation group (from 379.7 +/- 43.5 to 372.9 +/- 46.9 meters to controls and from 372.9 +/- 62.4 to 500 +/- 68 meters to electrostimulation, p<0.001). On the other hand, the walked distance in the control group did not change. Conclusion: The neuromuscular electrostimulation group showed greater improvement in the walked distance in the six-minute walking test in patients admitted to ward for compensation of heart failure.

Variação do espectro das ondas de Rossby na região da frente Brasil-Malvinas

A média global da variação na quantidade de calor armazenado nos oceanos observada recentemente é positiva (Cabanes et al., 2001; Cazenave & Nerem, 2004), porém, sua distribuição espacial não é homogênea (Polito & Sato, 2008). O calor armazenado está associado, via expansão térmica, à altura da coluna d'água. Portanto, variações espaciais na tendência do calor armazenado tem como consequência mudanças na inclinação da superfície que, por sua vez, implicam em variações nas correntes geostróficas e portanto na energia cinética associada a fenômenos de meso e larga escala. Polito & Sato (2008) observaram tendências predominantemente positivas na amplitude de ondas de Rossby e vórtices de mesoescala nos últimos 13 anos, sugerindo que estes eventos estão, em uma média global, ficando mais energéticos. Estas tendências variam regionalmente e a variabilidade espacial é mais pronunciada próximo da extensão para leste das correntes de contorno oeste (CCO), sugerindo um aumento do cisalhamento da velocidade geostrófica. O afastamento das CCO da costa provoca, na região de sua ocorrência, intensa atividade vortical e meandramento, constituindo, do ponto de vista da anomalia da altura da superfície do mar (AASM), as áreas mais energéticas do planeta. O exemplo no Atlântico Sul é a separação da Corrente do Brasil (CB) em sua região de encontro com a Corrente das Malvinas (CM). A CB flui quase-meridionalmente para sul até aproximadamente 36°S, iniciando seu afastamento da costa até 38°S devido ao encontro de suas águas quentes e salinas com as águas de origem subpolar da CM, conforme Garzoli & Garrafo (1989). Essa região recebe o nome de Confluência Brasil-Malvinas (CBM).
