In Deleuze＇s two books on cinema, the discussion of images demonstrates the entangled juxtaposition of the three levels： brain-thought, cinema-screen, and world-images that compose the cinematic consciousness. Through the interacted movement-images and time-images, the film unfolds the storyline within the aesthetic pleasure of poetic sentiment that gradually leads the audience to learn that a wandering boy, Hsiao-Hsiang, after the death of his father, has had several adventurous encounters that gradually expose the secrecy of his traumatic family： His birth mother has no decent job and his step-father has killed his own brother. This broken family has been haunted by the shared guilt and the undead memory as Derrida famously claims that hauntology precedes ontology. As the past coexists with the present, Deleuze analyzes the concept of I, with a central fracture in its pure form of the past demonstrating an ontological enigma that remains forever a secret. When the director uses the four portraits to indicate the four important events of this wandering boy, he deliberately leaves empty the fourth portrait, the self-portrait of the boy; it remains as an incomplete piece which symbolizes an enigma of his own life. It shows certain constitutive unnamable forces acting within the boy that seduces him forever to painfully misrecognize himself.展开更多

In this study, radiation damage is investigated in graphite, which is used as a neutron reflector in the Tehran Research Reactor (TRR) core. Radiation damage is shown by displacement per atom (dpa) unit. A cross section of the material was created by using the SPECOMP code. The concentration of impurities present in the non-irradiated graphite was measured by using the ICP-AES method. In the present study the MCNPX code had identified the most sensitive location for radiation damage inside the reactor core. Subsequently, the radiation damage (spectral-averaged dpa values) in the aforementioned location was calculated by using the SPECTER, SRIM Monte Carlo codes, and Norgett, Robinson and Torrens (NRT) model. The results of “Ion Distribution and Quick Calculation of Damage”(QD) method groups had a minor difference with the results of the SPECTER code and NRT model. The maximum radiation damage rate calculated for the graphite present in the TRR core was 1.567 9 10^-8 dpa/s. Finally, hydrogen retention was calculated as a function of the irradiation time.展开更多
