Sexual-Enhancement Drug Use in College-Age Men
… to explore the use of sexual-enhancement drugs (SEDs) in college men and to compare the men who had used SEDs to those who had not used them. Eighty-two male college students completed a questionnaire that included open-ended questions about their use of SEDs and items assessing their sexual …

Pharmaceutical analysis and in-vitro aerodynamic characterisation of inhaled theophylline formulations containing drug particles prepared by supercritical fluid processing. Chromatographic, spectroscopic, and thermal analysis of micron-sized theophylline particles prepared by supercritical fluid technology and in-vitro evaluation of their performance as inhaled dry powder formulations.
… enhanced dispersion by supercritical fluid (SEDS) process has been applied for the production of anhydrous theophylline as pure crystals in the range 2-5 ¿m to be used as new inhaled dry powder formulation for asthma. Fifteen theophylline samples have been prepared under different …

Search for rapidly star-forming galaxies at high redshift.
… CCD photometry to locate objects with peculiar SEDs. Using the IR data we should be able to locate rapidly star forming galaxies to z = 25. With a 3σ detection limit of 18.5 at K we have found no objects with z > 5 but we have found several blue objects at z < 4 in 16min² of sky. This suggests …

The broad spectral energy distributions of accreting white dwarfs
… on the broad spectral energy distributions (SEDs) of these objects. I perform such a study here, and present the largest collection of broad CV SEDs yet constructed. I define a sample of well-studied, nearby cataclysmic variables of several different CV classes, and gather existing …

Star formation in unobscured quasars
… span a redshift range of 0 < z < 4, and their SEDs give a mean SFR of ~1000M☉/year. When comparing these SFRs to the intrinsic properties of the quasars, we find no clear connections between the quasars and the ongoing star formation events in their hosts. We then look for evidence of AGN …

The FORS Deep Field Spectroscopic Survey
… were determined using a library of empirical SEDs derived from FDF mean spectra with very high S/N. The characteristics of the observed galaxy spectra are presented and the distribution of redshifts and spectral types are discussed. A first analysis of the excellent data set was carried out …

Plano Estadual de Assistência Social: o papel das diretorias regionais na formulação, avaliação e apoio à implementação
… Secretaria Estadual de Desenvolvimento Social (SEDS), o período pós-elaboração do PEAS tem se mostrado um momento desafiador no que se refere à implementação das diretrizes e projetos em âmbito regional. Consideradas como instâncias estratégicas no desdobramento das políticas estaduais de …

Models of Dust and Gas Tori in Active Galactic Nuclei
… of Seyfert galaxies. However, the model SEDs show too pronounced silicate emission features in the face-on case. This can be overcome with the help of three-dimensional clumpy tori, calculated in a second step. Special emphasis is put on the differences of clumpy and continuous dust …

The influence of planetary and stellar companions on debris discs
… sample of 341 multiple star systems, using their SEDs to identify and characterise their debris discs. I find that the stellar separation distributions of disc-bearing and disc-free systems differ with 99.4% confidence. No discs are detected for separations between 25 and 135 au, likely because …

Spectral Energy Distribution Modelling of X-ray Selected AGNs and Their Host Galaxies
… We also find that the use of lower resolution SEDs can lead to repercussions on property inferences such as host galaxy stellar mass, which may provide incorrect assumptions on the relation between AGN and their host galaxies.

The Andromeda Optical and Infrared Disk Survey
… of resolved stellar populations and panchromatic SEDs. We present the Andromeda Optical and Infrared Disk Survey (ANDROIDS), which adds new near-UV to near-IR (ugriJKs) imaging using the MegaCam and WIRCam cameras at the Canada-France-Hawaii telescope to the available M31 panchromatic dataset. To …

Far-UV to Mid-IR Spectral Energy Distributions of Nearby Merging Galaxies
… galaxy evolution. Spectral energy distributions (SEDs) allow Astrophysicists to disentangle AGN activity from SF. I hypothesize that applying SED analysis to a sample of merging galaxies will show an enhancement in AGN activity over control galaxies. I perform SED analysis from the far-ultraviolet …

The characterization of volatiles associated with young stellar objects
… Class II Spectral Energy Distributions (SEDs) have a larger abundance of CO₂ ice with respect to H₂O ice. In addition to intracloud differences, we compared our results with several other star forming regions, high mass YSOs, and background objects. The average abundance of CO₂ with …

A high energy perspective of the co-evolution of black holes and their host galaxies
… luminosity and spectral energy distributions (SEDs) of elusive AGN is of paramount importance. The recent COSMOS survey provides the necessary multiwavelength database to characterize the SEDs of a statistically robust sample of obscured sources. The combination of high X/O and red-colors …
