No full textRed Clump stars in the Boötes III stellar system
No full textWe report on the detection of a population of Red Clump (RC) stars probably associated with the recently discovered stellar system Boötes III. The RC is identified as a 3σ peak in the luminosity function (LF) of colour-selected stars extracted from the Sloan Digital Sky Survey data base. The peak is consistently detected in the g,r,i and z LFs at the expected luminosity of a typical RC at the distance of Boötes III. Moreover, the stars around the LF peak show a maximum of surface density nearly coincident with the reported centre of the system. Assuming that the detected feature is the genuine RC of Boötes III, we find that the system has the horizontal branch morphology typical of old and metal-poor dwarf spheroidals, it has an integrated magnitude MV ~= -5.8 +/- 0.5 and an ellipticity ɛ ~ 0.5, quite typical of the recently identified new class of very faint dwarf galaxies

Genetic diversity of cultivated cardoon to select high biomass producing genotypes
No full textWithin the frame of REBIOCHEM project funded by the Italian Ministry of Education, University and Research within the cluster on Green Chemistry, the paper aims at (i) assessing the potential ability of different cardoon accessions in terms of biomass production, (ii) selecting the most interesting genotypes and stabilizing them for genetic performances, (iii) evaluating selected genotypes for salt tolerance. Six accessions were evaluated by previously established morphological descriptors along a 3-year experiment, while 29 new accessions were recently collected and are currently being analyzed; all germplasm is now grown in a regional farmland of central Italy. Levels of genetic diversity in relation to biomass production and relatedness among accessions have been assessed. Development of stable selected lines is in progress. Some cardoon genotypes have been selected for specifically targeted raw material utilization such as aboveground biomass for extraction of useful compounds. The versatility of the cardoon biomass suggests its use as feedstock for different purposes, also implying an added value to the crop within a biorefinery context
Effect of Moisture Content on the Processing and Mechanical Properties of a Biodegradable Polyester
No full textThis work is focused on the influence of moisture content on the processing and mechanical properties of a biodegradable polyester used for applications in injection molding. The pellets of the biodegradable polyester were exposed under different relative humidity conditions at a constant temperature before being compression molded. The compression-molded specimens were again placed under the above conditions before the mechanical testing. With all these samples, it is possible to determine the effect of moisture content on the processing and mechanical properties separately, as well as the combined effect of moisture content on the mechanical properties. The results obtained showed that the amount of absorbed water—both before processing and before mechanical testing—causes an increase in elongation at break and a slight reduction of the elastic modulus and tensile strength. These changes have been associated with possible hydrolytic degradation during the compression molding process and, in particular, with the plasticizing action of the moisture absorbed by the specimens

Variations 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
