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
Prediction of the Behavior of a CNG Tank Exposed to Flames
No full textThe increasing request of vehicles fuelled by Compressed Natural Gas (CNG) requires that the safety issues related to this kind of fuel should be analyzed more and more thoroughly. So far, the minimum requirement for a CNG tank is to set up a Pressure Relief Device (PRD) triggered by temperature. This work aims to develop a procedure able to perform thoroughly tank behavior analyses, in presence of fire, in order to reduce the number of expensive experimental tests and to improve the design criteria of tank safety devices. The procedure consists in the solution of the unsteady solid-fluid conjugate heat transfer problem, by means of numerical simulations, in order to evaluate the transient behavior of both the temperature field inside the solid walls of the tank and the thermo-fluid-dynamic field of the compressed gas inside it, when it is exposed to a heating source. Moreover, the melting process of the fusible plug, inside the PRD, is simulated. In order to validate this procedure, experimental tests have been carried out on a suitable test rig. Several heating conditions, even unlikely, but able to jeopardize safety, have been considered. The condition characterized by a flame located on the opposite side of the PRD has been recognized to be the most critical with respect to explosion risk. In this case, the relationship between time and tank pressure has been numerically evaluated. The fusible plug, inside the PRD, has been checked to be completely melted of the fusible plug before the pressure reaches the safety limit
Dietary fatty acids intake: possible role in cognitive decline and dementia. Exp Gerontol
No full textThere is a recent increase in the level of interest in the possible role of dietary fatty acids in age-related cognitive decline, and cognitive
impairment of both degenerative (Alzheimer’s disease, AD) or vascular origin. At present, several studies suggested that an increase of
saturated fatty acids (SFA) could have negative effects on cognitive functions. Furthermore, a clear reduction of risk of cognitive decline has
been found in a population sample with a high intake of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA). These
findings were confirmed by studies in which high intakes of nK6 PUFA, nK3 PUFA, MUFA, and weekly fish consumption, providing large
amount of nK3 PUFA, appear to be protective against the risk of AD. In our elderly population from Southern Italy, elevated unsaturated
fatty acids intake (MUFA and PUFA), high levels of antioxidant compounds, and very low SFA intake could act synergistically in improving
cognitive performance. Epidemiological studies on the association between diet and cognitive decline suggested a possible role of fatty acids
intake in maintaining adequate cognitive functioning and possibly in preventing or delaying the onset of dementia, both of degenerative or
vascular origin. Appropriate dietary measures or supplementation with specific micro- and macronutrients might open new ways for the
prevention and management of cognitive decline and dementia
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]

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
Polymorphisms in the oxidized low-density lipoprotein receptor-1 gene and risk of Alzheimer 's disease
No full textThe þ1073 C/T polymorphism of the oxidized low-density lipoprotein receptor-1 (OLR1) gene
has been reported to be associated with late-onset Alzheimer’s disease, whereas for the þ1071
T/A polymorphism no association was found. We genotyped 169 sporadic Alzheimer’s disease
patients and 264 sex- and age-matched nondemented controls from Southern Italy for OLR1
þ1073 C/T and þ1071 T/A polymorphisms and for apolipoprotein E and LBP-1c/CP2/LSF. We
also performed haplotype analysis. For the þ1073 C/T polymorphism, the C allele and the CC
genotype have been associated with a higher risk for Alzheimer’s disease without apolipoprotein
E or CP2 interaction. The two polymorphisms were in linkage disequilibrium, with the haplotype
T-C at significant increased risk of developing Alzheimer’s disease in the whole sample and in
elderly persons 70 years or older. In our population, the þ1073 C/T OLR1 polymorphism exhibited
a significant association with Alzheimer’s disease, further supporting the role of OLR1 as
a candidate risk gene for sporadic Alzheimer’s diseas
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
Dietary intake of unsaturated fatty acids and age-related cognitive decline: A 8.5-year follow-up of the Italian Longitudinal Study on Aging
No full textThere is evidence from a population-based study of an inverse relationship between monounsaturated fatty acids (MUFA) energy intake and age-related cognitive decline (ARCD), while high polyunsaturated fatty acids (PUFA) intake was positively associated with cognitive impairment in elderly subjects. We investigated the possible role of MUFA and PUFA on age-related cognitive changes. A population-based, prospective study was carried out on 278, 186, and 95 nondemented elderly subjects (65-84 years) evaluated for global cognitive functions (Mini-Mental State Examination, MMSE) at the first (1992-1993), second (1995-1996), and third survey (2000-2001), respectively, from the randomized cohort of Casamassima, Bari, Italy (n=704), one of the eight centers of the Italian Longitudinal Study on Aging (ILSA). MUFA and PUFA intakes were assessed at baseline with a semi-quantitative food frequency questionnaire. High MUFA and PUFA energy intakes and total energy intake were significantly associated with a better cognitive performance in a 8.5-year follow-up. In this prospective population-based study on older nondemented subjects with a typical Mediterranean diet, high MUFA and PUFA intakes appeared to be protective against ARCD
