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
[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
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
Preparation and Characterisation of Binder-Free All-Cellulose Composites
No full textThe copyright of this thesis rests with the author and no quotation from it or information derived from it may be published without the prior written consent of the authorA recent emerging concept of all-cellulose composites within the field of
environmentally friendly materials has received increasing attention. The main
advantage of these materials is the lack of using additional bonding agents such as
polymer resins as in the case of e.g. phenolic resin based panel products or natural
fibre reinforced plastics that increase their environmental impact. Two different
routes for the production of all-cellulose composites have been followed. The
obtained materials were characterised by scanning electron microscopy, X-ray
diffraction, flexure and tensile mechanical tests, thermogravimetric analysis,
pycnometry and water absorption tests.
The first strategy makes use of the selective dissolution method where the
cellulose fibre skins are partially dissolved to form a matrix phase that bonds the
fibres together, while the strong core fibres are maintained and impart a reinforcing
effect to the composites. The influence of the dissolution time, activation time and
the fibre source were assessed. It was found that a dissolution time of 18 h led to
materials with the best overall mechanical performance (5.5 GPa and 145 MPa for
Young’s modulus and tensile strength, respectively), as this time allowed for the
dissolution of a sufficient amount of fibre surface to obtain good interfacial bonding
between fibres, while keeping a considerable amount of remaining fibre cores that
provide a strong reinforcement to the composite, leading to materials that outperform
natural fibres reinforced polypropylene composites.
Still, the previous methodology has the drawback of using chemical
substances of high environmental impact (solvents). In order to overcome this, a new
concept in the production of all-cellulose composites is proposed in this work, which
makes use of the intrinsic bonding capability between cellulose fibres to enhance the
hydrogen bond network in order to produce materials of good mechanical
performance. A new experimental procedure was developed, based on the refinement

of cellulose fibres in order to increase their specific surface area, thus increasing the
interfibre bonding capability, and achieving materials with excellent mechanical
properties, up to 17 GPa and 119 MPa for flexural modulus and strength,
respectively, and low water absorption. These new high-performing environmentally
friendly materials are based on renewable resources and are 100% recyclable and
biodegradable.Financial support from the Engineering and Physical Sciences Research

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
