Cinema as a mirror of postrevolutionary cultural negotiations. After the revolution, Iranian cinema becomes a shared format for national self-representation. Despite censorship and practical constraints, filmmaking developed a coded but locally recognizable language to explore tensions around class, region, gender, history, and politics. Acquiescing to censorship requirement that women actors never unveil, even when represented in private alone or with other women, filmmakers and audiences found themselves undermining the dramatic artifice of the cinematic fourth wall, the convention of invisible, passive dramatic observation taken for granted in modern filmmaking. Instead, audiences became collaborators of cultural meaning, acknowledging cinematic artifice and the possibilities of symbolic representation. Canny directors involved their viewers as conscious partners in a community of interpretation, pushing the limits of cultural critique. These self-reflexive Iranian films provide the most accurate format for reflecting on postrevolutionary national and political developments, making postrevolutionary Iranian cinema a mirror for national subjectivity and society.
We investigate the energetics of mixing induced by a continuously supplied dense current (density $\rho _0$) propagating beneath a lighter ambient fluid (density $\rho _a$) along a horizontal rigid boundary within a rectangular domain. The flow fields are computed using direct numerical simulations (DNS) performed with the Nek5000 spectral element solver. Mixing is quantified through the temporal evolution of the background potential energy, which exhibits a linear increase over time. This linear trend enables the definition of a dimensionless mixing parameter $\gamma$, representing the rate of background potential energy growth. The value of $\gamma$ depends on the initial density contrast for a fixed volumetric discharge at the source, characterised by the dimensionless source Froude number. The results reveal a non-monotonic dependence of $\gamma$ on the source Froude number, highlighting a complex interaction between flow forcing and mixing efficiency. We find that, under the assumption of uniform mixing along the current’s length, a fraction $\gamma /2$ of the total supplied energy is invested in mixing along a horizontal distance equal to the height of the inlet.
Dietary phytosterols exert hypocholesterolemic effects by inhibiting cholesterol absorption in the small intestine. However, oxidised phytosterols exert harmful effects. In this study, we compared the effects of dietary stigmasterol or oxidised stigmasterol (OS) on cholesterol absorption and metabolism in mice. Institute of Cancer Research (ICR) male mice were fed one of the following diets: a standard American Institute of Nutrition (AIN) diet; the standard diet plus 0·25 % cholesterol; the standard diet plus 0·25 % cholesterol and 0·25 % stigmasterol or the standard diet plus 0·25 % cholesterol and 0·25 % OS. Stigmasterol, but not OS, decreased plasma total cholesterol levels. Unlike stigmasterol, dietary OS increased the cholesterol levels in micellar solutions. Thus, OS could not exert hypocholesterolemic effects as it could not displace cholesterol in micellar solutions. In contrast, dietary OS downregulates the mRNA expression of genes involved in cholesterol synthesis and upregulates the mRNA expression of genes involved in cholesterol catabolism in mice fed cholesterol. In addition, dietary stigmasterol and OS increased the levels of faecal-neutral steroids by downregulating the mRNA expression of Niemann-Pick C1-like 1 protein (NPC1L1) in the small intestine. Dietary stigmasterol may directly regulate the mRNA expression of NPC1L1, whereas dietary OS may reduce the mRNA expression of sterol regulatory element-binding protein 2 and act as a Liver X receptor α agonist, reducing the mRNA expression of NPC1L1. Therefore, OS may affect cholesterol absorption and metabolism through a mechanism different from that of stigmasterol.
A theoretical intervention into the challenge of thinking through the complexities of life, in Iran or elsewhere. Hannah Arendt and Michel Foucault offer us a model of thinking as a practice. Each attempted one project in which they were thinking systematically about ongoing events, and offering that thinking as a contribution to public understanding. Arendt traveled to Jerusalem to observe the Adolf Eichmann trial, and her contemporaneous writing was published in The New Yorker magazine. Foucault traveled to Iran to observe the early stages of the revolution, and his contemporaneous writing was published (mostly) in the Corriere della Sera newspaper. These two projects have commonly been regarded as their author’s most controversial and have often been ignored or used to denigrate the writer’s entire theoretical oeuvre. Yet they offer compelling models of thinking as a practice that critically links the self and the world. Rescuing theory from the confines of academic specialization restores it, and us, to the possibility of thinking as a practice of freedom, and freedom as the daily possibility of beginning anew.
Skinfold callipers are used internationally in research, clinical and field settings to assess body composition and nutritional status. Notably, currently available instruments differ in important specificities that impact measurement. In this sense, this report proposes a methodological approach that organises skinfold callipers into three categories (Original, Generic and Hybrid) and three configurations (Type A, Type B and Type C) based on physical-mechanical properties and characteristics. Therefore, this concept provides technical support for choosing the most appropriate skinfold calliper in different contexts.
Carbon-14 (14C) is an important contributor to the collective effective dose to the public due to releases from nuclear power plants (NPPs). In Sweden, only airborne emissions of 14C from NPPs are currently routinely monitored, and the existing data on waterborne 14C discharges are limited. A recent study of 14C in brown algae (Fucus spp.) in Swedish coastal waters showed higher F14C values collected at Ringhals NPP, on the Swedish west coast, than expected. Therefore, this study aimed at assessing if blue mussels (Mytilus edulis) could be used to retrospectively estimate the 14C concentration of dissolved inorganic carbon (DIC) in seawater at three sites. A method was developed to extract the fibrous layer that forms visible annual structures in the shells. All samples were analyzed with accelerator mass spectrometry and the results compared with 14C data from Fucus spp. For one of the analyzed shells (structures from 1974–1978), from the site Särdal, F14C in Fucus spp. and M. edulis agreed very well. For another shell (1972–1978), shell structures from some of the earlier years displayed up to 6% lower F14C than Fucus spp. F14C in one shell from a remote site, Båteviken, only had small annual variations (2017–2022: F14C = 1.070 ± 0.015 (1 σ)). Two shells from Ringhals NPP had higher average F14C, and a significant temporal variability (2014–2022: F14C = 1.427 ± 0.268 (1 σ)). Difficulties in unambiguous identification of the annual structures in the shells, as well as the future potential of this method, are discussed.
A work of compact dual-port transparent multiple-input multiple-output antenna optimized for fifth-generation (5G) N77 (3.3–4.2 GHz) and N78 (3.3–3.8 GHz) bandwidth has been simulated, investigated, and optimized for robust performance in high-speed wireless communication. It features an impedance bandwidth of 3–4.3 GHz with a minimum simulated return loss of −28 dB, with 100% 3-dB axial ratio bandwidth and a simulated gain of 3.5 dB. The conducting plane material is indium tin oxide (ITO), chosen for its high optical transparency and sufficient electrical conductivity to seamlessly integrate into visually demanding applications. The substrate is glass, chosen for its lightweight and durable properties, which enhance both the mechanical durability of the antenna and its electromagnetic performance. To validate the ITO-based simulated design, the prototype with the same geometrical specification has been fabricated with the conducting portion replaced with copper and substrate as glass material due to a lack of facilities for transparent antenna fabrication. The comparative investigation study between the proposed ITO-based transparent antenna and with copper-based prototype (simulated/measured) both on a glass substrate, has been discussed, which supports the findings.
The book ends by tracking the legacy of the Minorities Commission. The commission set a precedent for managing minority anxieties as Nigeria entered nation-statehood in 1960. It also failed to resolve the political tension these anxieties caused, leaving the newly independent Nigerian state with a crisis of citizenship that lingers to this day. This crisis of citizenship informed the national breakdown that led to the devastating civil war (also known as the Biafran War, 1967–70) and the ongoing fragmentation of Nigeria into smaller and more numerous states. Because certain Niger Delta peoples have been fixed as minorities in Nigeria, the needs and well-being of Niger Delta communities are not priorities, especially as they are construed as being at odds with national needs and priorities. It is in this context that their status as minorities has had the most devastating implications. The book closes by exploring the various ways these communities have used their minority status to simultaneously challenge and insist upon inclusion within the Nigerian state, asking what might be possible for their future as Nigerian citizens.
The minority claims made by the various minority movements that emerged in the 1950s coalesced in separate state movements. Separate states claims were made by minority communities in all three major regions and these claims were championed by their political elites who strategically occupied seats in the regional houses of assembly, starting in 1953. Niger Delta elites formed provisional alliance, supressing local disputes and differences, in order to keep their claim for a separate Mid-West state alive in the constitutional reform process. Their efforts succeeded in halting the final constitutional conference, which was to be held in London in 1957. The push for separate states was strong enough to threaten the decolonization process altogether, and the British government decided to establish a Minorities Commission to address and resolve these claims prior to formal independence.
This chapter explores the intersection of historical linguistics and psycholinguistics by investigating the role of core psycholinguistic factors and phenomena in language change: frequency, salience, chunking, priming, analogy, ambiguity and acquisition. Recent research from cognitive sciences, particularly within a complex systems framework, reveals that language change is influenced by patterns of use and is interconnected with language acquisition and cognition. Bridging the gap between community and individual research, the chapter highlights studies that explore this relationship. It also examines the potential of psycholinguistic methodologies for diachronic research. Additionally, the chapter suggests avenues for further research where psycholinguistic perspectives have had less impact on the study of historical language change. Furthermore, it discusses how psycholinguistic factors have been incorporated into various theoretical approaches to English language change, such as generative and usage-based modelling.
In two of Kierkegaard’s earliest works, The Concept of Irony and Either/Or, imaginary construction (i.e., thought experiment, or Experiment) is often characterized negatively. However, the three core features of thought experiment shared by Ørsted and Mach also begin to emerge, laying foundations for a more positive view in other works. Kierkegaard’s characterizations of thought experiment indicate that imaginary construction guides mental action. This focus contrasts with the standard emphasis in Kierkegaard scholarship on thought experiment as supplying the concreteness of (empirical) actuality. In The Concept of Irony, Kierkegaard critiques irony as a retreat from reality but also shows it can be used to achieve new kinds of wholeheartedness and unity. In this chapter, I will argue that thought experiments can similarly lead the experimenter away from reality but, like irony, may also be a useful tool for self-development.
In 1636, a set of nine paintings was installed on the ceiling of the Banqueting Hall in Whitehall Palace. Three central and six side panels. The set had arrived from the studio of Peter Paul Rubens in Antwerp, and had been commissioned by King Charles I in honour of his father James. They were intended to summate three aspirations which defined James’s reign. The three central panels were entitled The Apotheosis of King James, The Peaceful Reign of King James, and The Union of Crowns. Each spoke to a matter of constitutional urgency, then and now; respectively, the nature of monarchy, relations with the rest of Europe, and the possibility of forging a union between England and Scotland. The purpose of this chapter is to revisit the reign of King James I and see if we can spot some resonances.
Chapter 5 explores a wide range of passages where the Sectarians identify themselves as the present-time victims or potential victims of violence perpetrated by empowered others: Rome and the local Jewish priestly and political authorities. The imagery of the powerful priests in Jerusalem and their leader the Wicked Priest waging a campaign of violence and intimidation against the Sectarians is part of a broader attempt by the disempowered and disenfranchised Sectarians to craft a narrative of victimhood.
The present article investigates the stability of Rayleigh–Bénard convection in a composite system consisting of a horizontal fluid layer overlying a fluid-saturated Darcy porous layer subjected to a time-periodic temperature distribution. The bottom surface is heated periodically with time, whereas a Biot number-dependent thermal boundary condition represents the heat transfer at the upper surface. The Beavers–Joseph–Saffman–Jones condition describes the ‘slip’ at the interface of the domains, and the Lions interface condition governs the normal force balance, incorporating a dynamic pressure term. The Chebyshev tau method and Fourier analysis are utilised to obtain linear instability bounds, which are compared with strong global and asymptotic limits derived from the nonlinear analysis using the energy method. Four deliberately chosen configurations of superposed fluid- and porous-layer systems are investigated. Two configurations validate the analysis through the limiting cases of the classical Darcy–Bénard and Rayleigh–Bénard systems obtained by setting the fluid-to-porous depth ratio $(\hat {d})$ to zero and infinity, respectively. The other two configurations involve layers with equal depths $(\hat {d} =1)$ and a shallow fluid layer overlying a porous layer $(\hat {d} \sim 0.1)$. For these cases, modulation substantially influences the onset of convection. In the last case, the linear theory points out that modulation parameters can control the dominant convective mode (fluid/porous). Furthermore, unlike the previously reported studies, the nonlinear stability bounds are found to be significantly lower than the linear instability bounds, indicating the possibility of subcritical instabilities in the presence of modulation. The region of subcritical instabilities increases with modulation amplitude.
This chapter focuses on the way the Livian conception of political leadership reflects the corresponding Ciceronian theory. Although Livy does not seem to use any specific term for ‘leadership’, the latter is given a prominent role in his theory regarding the progress and the decline of the res publica: in his much-commented-on passage of his preface (praef. 9), both the relaxation of disciplina and the role of the leaders (uiri) are elucidated by reference to Cicero’s theory and terminology of leadership. Disciplina should then be defined as a way of moral and political life transmitted from one generation to the other, which is essentially based on the principle of obedience to an ‘enlightened’ political leadership. The characteristics of efficient leadership are expressed by Livy in various comments or speeches throughout the work. The role attributed to the people and the leaders in Livy’s scheme also reveals a close affinity with Cicero’s theory of the ideal leader as a moderator rei publicae, especially in the De re publica. Livy also promotes some leaders of the Roman past as exempla which have incarnated the Ciceronian ideal of leader.
