The IACOB project
No full textContext. We are now in an era of large spectroscopic surveys of OB-type
stars. Quantitative spectroscopic analysis of these modern datasets is enabling us to
review the physical properties of blue massive stars with robust samples, not only
revisiting mean properties and general trends, but also incorporating information about
the effects of second-order parameters.
Aims. We investigate the spectral type – effective temperature
(SpT – Teff) calibration for O-type dwarfs and
its claimed dependence on metallicity, using statistically meaningful samples of stars
extracted from the IACOB and VFTS surveys.
Methods. We performed a homogeneous differential spectroscopic analysis
of 33 Galactic and 53 LMC O dwarfs (spanning spectral types of O4 – O9.7) using the
iacob-gbat package, a χ2-fitting algorithm based on a large
pre-computed grid of fastwin
Quality management system and accreditation of measurements on scientific high-level technological laboratory. The case study of MiNALab
No full textVariations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Broadband Dielectric Spectroscopy (BDS) investigation of molecular relaxations in durum wheat dough at low temperatures and their relationship with rheological properties
No full textBroadband Dielectric Spectroscopy (BDS) was used to study the dielectric relaxation processes of semolina doughs. The dielectric properties were analyzed as a function of water content, and, additionally, the effects of NaCl presence and semolina characteristics were investigated. The dough was prepared using three different varieties of semolina. BDS measurements were conducted using a custom-made Rheo-dielectric tool composed of a Broadband Dielectric/Impedance Spectrometer connected to a strain-controlled rheometer. The temperature range investigated was from −135 °C to 25 °C, with a step of 5 °C, while the frequency range was 10−1 – 107 Hz. Dielectric spectroscopy turned out to be a valuable technique for dough characterization. It is capable to distinguish the carbohydrates contribution and the different interactions between water and dough components. Moreover, this unique combination allows assessing correlations between rheological and dielectric properties, like the compliance of dough as a function of the relaxation processes and the influence of semolina components
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
