Powers of Powerlessness: The Politics of Defeat in the Cinema of Nouri Bouzid
No full text This article examines the cultural politics of defeat in the cinema of Tunisian filmmaker Nouri Bouzid. Taking a lead from Bouzid’s directorial début Man of Ashes, the author focuses on Golden Horseshoes (1989) and Making of (2006), the two films that best dramatize the continuities between the crisis of filiation and the crisis of affiliation, and that deal head-on with left-wing (socialism) and right-wing (religious fundamentalism) ideologies. These two early films paint the broad strokes of Bouzid’s cinematic project, specifically its entwined dramatization of the crisis of filiation ( Man of Ashes) and the crisis of affiliation ( Golden Horseshoes), the profound loss of any discernible project of psychoaffective investiture, intellectual commitment and decolonial resistance, especially in the wake of the spectacular dissolution of international socialism and the ensuing triumphalism of global capitalism and financial imperialism. </jats:p

No full text© 2021 Author(s).We report the strong ferromagnetic order in van der Waals (vdW) layered SnS2 induced by cobalt substitution. The single-crystal Co-doped SnS2 grown by a self-flux method reveals a relatively high Curie temperature (TC) of ∼131 K with an in-plane magnetic easy axis and a large saturation magnetization of ∼0.65 emu g-1 for the 2 at. % Co concentration, which is two orders of magnitude larger than the previously reported value for transition-metal-doped SnS2. The average magnetic moment per Co atom, as high as 1.08 μB, is consistent with the calculated value based on density functional theory, i.e., 1 μB, indicating a negligible antiferromagnetic coupling between Co atoms. Magnetoresistance shows a change in sign from positive to negative, which further confirms the ferromagnetic order in Co-doped SnS2. Our s-p hybridized vdW layered SnS2 serves as a host semiconductor material to search for a suitable magnetic dopant with a high magnetic moment and room temperature TC for next-generation spintronics.11Nsciescopu
A non-conforming finite element method with anisotropic mesh grading for the Stokes problem in domains with edges
No full textIntroduction The solution of the Stokes system in polygonal or polyhedral domains has, in general, singular behaviour near corners and edges of the domain. Hence standard numerical methods lose accuracy on quasiuniform meshes, and locally refined meshes are proposed. Two-dimensional problems with corner singularities have been analyzed by Becker & Rannacher (1995), Orlt & S andig (1995), and El Bouzid & Nicaise (1998). These last authors extend their results to polyhedral domains where edge and corner singularities may appear. El Bouzid & Nicaise (1998) and Orlt & S andig (1995) use isotropic (regular in Ciarlet's sense) meshes refined in a neighbourhood of the singular edges and corners to compensate for the singular behaviour of the solution. In three-dimensional problems this method leads + Corresponding author. Email: [email protected] # Email: [email protected] Email: [email protected] c The Institute of Mathematics and its Appl

Parametric Analysis of Liquid Ammonia Direct Injection for Optimal Ammonia-Hydrogen Combustion in Spark-Ignition Engines
No full textSons of a Beach
No full textThis article examines the cultural politics of bastardy in the films of Tunisian filmmaker Nouri Bouzid at a time when questions of national and cultural identity have come to the fore in Tunisia in the wake of the Revolution of Freedom and Dignity. Nouri Bouzid is the doyen of Tunisian cinema. Not only was he involved in every major postcolonial film, whether as a screenwriter, a scriptwriter, or even as an actor, but he single-handedly directed more than half a dozen films, each of which enjoyed wide national and international acclaim. His debut film, Man of Ashes, dramatizes the trauma of child molestation and the collapse of filial relations as well as the emergence of a new generation of men who seek to recast filial and familial relations beyond blood ties and familial limitations. This same cinematic pursuit is further developed in his later films with striking consistency and perseverance. At a time when the postrevolutionary public sphere is saturated with heated debates around Tunisian national identity, propelled by fantasies of purity and virile filiation, Bouzid’s bastard characters serve, the author argues, not only to warp and reclaim the political playing field for revolutionary purposes but also to remind Tunisians of the disturbing legacy of bastardy (instituted by a long history of colonial rape from the Romans to the French) to which they had been and continue to be heirs, and with which they have to reckon. Studying the rhetoric of bastardy in Bouzid’s cinema leaves us in the end with the touching yet unsparing conclusion that for Bouzid there are no Tunisians until they have assumed their bastardy.</jats:p
A Study on the Contact Quality Improvement of Fin to Tube Assemblies
No full textThe fin-to-tube assembly is a prevalent connection type in heat exchangers, particularly in smaller equipment. During the assembly process, a die expands the tube to close the gap between the tube and the fin collar, enhancing heat transfer. The die expansion reduces the gap and creates slight interference that enables the fin collar to adhere to the tube. However, contact is not uniformly continuous across the width of the mating surfaces, as indicated by recent research. Due to this suboptimal contact quality, the conduction of heat is significantly impaired, and the efficiency of the heat exchanger is thus compromised.
This study aims to establish a relationship between the profile shape of the fin hole and the contact quality, offering guidelines to enhance tube-to-fin contact. Tubes of various materials, dies of different sizes, and fins with a collar featuring an hourglass proposed shape are examined. The influence of a fin-hole hourglass shape will be assessed through a series of expansion simulations conducted on diverse finite element models. Subsequently, the micro-gaps formed during the expansion process at the tube-to-fin interface will serve to evaluate the quality of the contact surface, and a thermal transient analysis will be implemented to corroborate the findings.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.
