This article aims to analyse the historical, political, and socio-cultural significance of the Alash Orda movement in shaping Kazakh national identity and the quest for autonomy during the early 20th century. The research draws on a range of primary sources, including archival documents and speeches, as well as scholarly works by Kazakh and international historians. It analyses how Alash leaders developed a multifaceted political strategy to secure autonomy amidst the chaotic transition from imperial rule to revolutionary governance. Central to their approach was diplomacy: the Alash Orda government sought to establish ties with the Russian Provisional Government and A. Kolchak’s White Army, aiming to build alliances supportive of Kazakh autonomy. The movement also reached out to international organisations, seeking external recognition and assistance. Despite these efforts, the study demonstrates that Alash Orda ultimately failed to achieve lasting success in establishing a stable autonomous Kazakh state. Alongside this political narrative, the study highlights the cultural and educational initiatives of Alash Orda, particularly its promotion of the Kazakh language and national identity in the face of Russification policies.
Finite-amplitude spiral vortex flows are obtained numerically for the Taylor–Couette system in the narrow limit of the gap between two concentric rotating cylinders. These spiral vortex flows bifurcate from circular Couette flow before axisymmetric Taylor vortex flow sets in when the ratio $\mu$ of the angular velocities of the outer to the inner cylinder is less than −0.78, consistent with the results of linear stability analysis by Krueger et al. (J. Fluid Mech., vol. 24, 1966, pp. 521–538), while the boundary of existence of spiral vortex flows is determined not by the linear critical point, but by the saddle-node point of the subcritical spiral vortex flow branch for $\mu \lessapprox -0.75$, when the axial wavenumber $\beta =2.0$. It is found that the nonlinear spiral vortex flows exhibit the mean flow in the axial direction as well as in the azimuthal direction, and that the profiles of both mean-flow components are asymmetric about the centre plane between the gap.
London’s nineteenth-century sailortown – centred around Ratcliffe Highway and the surrounding docklands – was a vital hub of maritime activity. Yet much of what is known about this space derives from landsmen’s accounts: narratives by Victorian reformers, novelists and journalists who often portrayed the sailortown as a site of crime, vice and moral degeneration. In contrast, sea shanties, rooted in the lived experiences of sailors themselves, offer an alternative perspective, illuminating the values and self-perceptions of the maritime community. This article examines how London’s sailortown is represented in shanty repertoire, analysing the lyrics of shanties associated with the city to reveal recurring themes, such as encounters with women, financial exploitation, alcohol consumption and the dangers of the Highway. These songs provide insight not only into the everyday lives of sailors ashore but also into how they navigated and interpreted urban spaces. Furthermore, by considering the broader soundscapes of the docklands (including the influence of street performers, public houses and the music hall), this study explores how urban auditory culture shaped the content and form of shanties. By highlighting sailors’ voices through their songs, this article reconstructs a more nuanced and culturally embedded understanding of London’s sailortown and its place within the wider maritime world.
In this work the fascinating dynamics of a two-layered channel flow characterised by the dispersion in composite media within its layers is investigated in depth. The top layer comprises of a fluid zone that allows the fluid to travel along its surface easily (with relatively higher velocity), while the bottom layer is packed with porous media. The primary objective of this research is to do an in-depth investigation of the complex two-dimensional concentration distribution of a passive solute discharged from the inflow region. A multi-scale perturbation analysis approach has been implemented to address the system’s inherent complexity. This accurate determination of the dispersion coefficient, mean concentration distribution and two-dimensional concentration distribution is accomplished deftly using Mei’s homogenisation approach up to second-order approximation, which satisfactorily capture the minor variations in the solute dynamics also. The influence of various flow and porous media elements on these basic parameters is thoroughly investigated, expanding our comprehension of the complex interaction between flow dynamics and porous media’s properties. The effect of Darcy number and the ratio of two viscosities ($M$) on the dispersion coefficient depends on the height of the porous layer. As the Péclet number ratio increases, the dispersion coefficient experiences a concurrent increase, resulting in a decline in the concentration peak. The results of the analytical studies have also been compared with those results obtained using a purely computational method to establish the validity of our studies. Both the sets of results show quite good agreement with each other. In this study, alternate flow models have been used for the porous region, and the outcomes are compared to determine which approach yields more suitable results under different conditions.
This article revisits the concept of the ‘Christian city’ in Late Antique North Africa by shifting the focus from topography to the lived and perceived urban experience. While earlier scholarship has emphasized the accumulation of Christian buildings, this study argues that religious transformation is equally, if not more, visible through the evolving practices of city inhabitants. By analysing both Christian and continuing pagan traditions between the fourth and seventh centuries, the article explores how monuments and public religious practices shaped the perception and function of the city. Special attention is given to the volumetric presence of sacred architecture and to the role of public spaces, particularly streets, in hosting religious acts. Ultimately, the study offers a more nuanced understanding of the Christian city: one defined not solely by the presence of basilicas, but by the rhythms, gestures, and visibility of religious life within the broader civic landscape.
This essay argues that the women, life, freedom movement should be understood as crucial site for the study of revolutionary praxis and feminist theory from which scholars and activists around the world can learn. While much attention has been given to efforts to co-opt the movement by monarchist and other “regime change” factions in diaspora, a lesser-known diasporic consequence has been the creation of Iranian feminist collectives oriented around intersectional and anti-colonial forms of transnational solidarity. By analyzing three such collectives that aimed to uplift critical feminist orientations emerging from the uprising in Iran, I chart shifts in ideas about organization, the meaning of revolution, and the contours of a “decolonial” feminist analysis in the Iranian context. I argue that these Iranian feminist collectives have built on the transnational feminist practice of making connections across differences, placing their critique of the Iranian state in relation to other iterations of patriarchal and militarized authoritarianism globally, including in the west.
This article explores biophilic (nature-centred) instrument design and its intersection with architecture and music. While the connection between these disciplines is often discussed figuratively, they are less often combined in practice. The Biophilic Instrument Pavilion (BIP), a site-responsive sound and light installation, serves as a model for such a collaboration using biophilic design as a unifying principle. This multidisciplinary project demonstrates spatialisation in ecological, sonic, visual and social contexts, offering insights into environmental instrument practices and collaborative creative processes.
The paper discusses the stochastic dynamics of the vortex shedding process in the presence of external harmonic excitation and coloured multiplicative noise. The situation is encountered in a turbulent practical combustor experiencing combustion instability. Acoustic feedback and turbulent flow are imitated by the harmonic and stochastic excitations, respectively. The Ornstein–Uhlenbeck process is used to generate the noise. A low-order model for vortex shedding is used. The Fokker–Planck framework is used to obtain the evolution of the probability density function of the shedding time period. Stochastic lock-in and resonance characteristics are studied for various parameters associated with the harmonic (amplitude, frequency) and noise (amplitude, correlation time, multiplicative noise factor) excitations. We observed that: (i) the stochastic lock-in (s-lock-in) boundary strongly depends on the noise correlation time; (ii) the parameter sites for s-lock-in can be approximately identified from the noise-induced shedding statistics; and (iii) stochastic resonance is significant for some intermediate correlation times. The effects of the above-mentioned observations are discussed in the context of combustion instability.
In the last few years, Hindu nationalism’s effort to shape the Hindu identity of the nation has intensified. Apart from its move to assert cultural homogenisation over the diverse landscape, this ideology produces a newer understanding of spaces in the land. When it is read as a part of the broader Hindutva movement, the use of violence, bureaucratic overreach, or judicial intervention to rewrite the sacred topography of the land unmasks the territorial goal of Hindu Rashtra. The territorial manifestation of this ideology takes a strident effort inside the country to encroach and reclaim the spaces inhabited by the “other” as Hindu spaces in the name of the nation. This immediately establishes a clear and precise correlation between the spaces and the nature of the spaces. This territorialisation of the spaces indicates the spatial rearrangement of the public spaces to marginalise minorities, invisibilise Muslims, and push them into the “private” space.
The disciples of St Thomas Aquinas have organized their enquiries in diverse ways throughout the history of Thomism. The surge of reinvigorated interest in Thomas Aquinas following Leo XIII’s Aeterni Patris inspired a wide variety of purported types of Thomism in the twentieth century. What should Thomists of the twenty-first century learn from their inheritance of past centuries of Thomism? How can they take up Leo XIII’s call vetera novis augere et perficere. I aim to address two issues in this essay. First, to identify a more principled demarcation of approaches to Thomistic enquiry, which eschews the commonplace but problematic and merely sociological classifications of the last century’s ‘schools’ of Thomism. I argue that a more principled and agenda-setting criteria distinguishes “defensive-constructive commentary Thomism” and “tradition-constituted-enquiry Thomism”. The first stresses fidelity to the conclusions found in careful readings of Aquinas’s texts. The second emphasizes fidelity to Aquinas’s systematic forms of enquiry directed to the truth. Second, I then probe the resources these two forms of Thomism have for addressing the epistemological crises facing Thomism, focusing on those concerning how to engage the nova of the sciences and rival philosophical traditions.
Large numbers of relative periodic orbits (RPOs) have been found recently in doubly periodic, two-dimensional Kolmogorov flow at moderate Reynolds numbers ${\textit{Re}} \in \{40, 100\}$. While these solutions lead to robust statistical reconstructions at the ${\textit{Re}}$ values where they were obtained, it is unclear how their dynamical importance changes with ${\textit{Re}}$. Arclength continuation on this library of solutions reveals that large numbers of RPOs quickly become dynamically irrelevant, reaching dissipation values either much larger or smaller than the values typical of the turbulent attractor at high ${\textit{Re}}$. The scaling of the high-dissipation RPOs is shown to be consistent with a direct connection to solutions of the unforced Euler equation, and is observed for a wide variety of states beyond the ‘unimodal’ solutions considered in previous work (Kim & Okamoto, Nonlinearity vol. 28, 2015, p. 3219). However, the weakly dissipative states have properties indicating a connection to exact solutions of a forced Euler equation. The dynamical irrelevance of many solutions leads to poor statistical reconstruction at higher ${\textit{Re}}$, raising serious questions for the future use of RPOs for estimating probability densities. Motivated by the Euler connection of some of our RPOs, we also show that many of these states can be well described by exact relative periodic solutions in a system of point vortices. The point vortex RPOs are converged via gradient-based optimisation of a scalar loss function which (i) matches the dynamics of the point vortices to the turbulent vortex cores and (ii) insists the point vortex evolution is itself time-periodic.
This paper examines clothing depicted in the portraits painted on the walls of the tombs of elites at various settlements in Campania and Lucania in southwest Italy in the fourth century BC, as it provides important information on sartorial appearances and self-perception, especially in view of the dearth of textiles and lack of textual sources. It investigates the interconnected relationship between dress behaviour, ethnic identity and social status among independent Italic groups in the region in this century, a time of political and cultural tensions triggered by Rome’s aggressive expansion of its territorial control. The images, as well as the material culture from grave assemblages, indicate that people expressed who they thought they were through clothing and dress accessories and that this happened on a local basis rather than on a large scale or ‘national’ level. It was predominantly women who were expressing group belonging through specific garments and styles, headdresses, colours and patterns. These images painted for perpetuity offer us a precious window on dress behaviour and they suggest that women were the primary bearers of small-scale community identities in funerary representation and in life in this period of political and social change.
The Syrian Civil War (SCW) began in 2011 and has resulted in numerous cases of war-related civilian injuries. The modified Rapid Emergency Medicine Score (mREMS) is widely used as an effective tool for assessing clinical status and mortality risk, particularly in intensive care units (ICUs) and emergency departments (EDs). However, to date, no study has evaluated the ability of mREMS to predict mortality in patients injured during the SCW.
Study Objective:
The primary objective of this study was to evaluate the performance of mREMS in predicting in-hospital mortality among adult trauma patients injured during the SCW. The secondary objective was to analyze the epidemiological characteristics of both adult and pediatric populations affected by the SCW.
Methods:
This single-center, retrospective observational study included patients who were injured during the SCW and presented to the ED from January 2012 through January 2016. Data from 4,074 adult patients and 1,379 pediatric patients were analyzed. The diagnostic and prognostic performance of the mREMS was specifically assessed in the adult cohort. Additionally, an epidemiological evaluation of the demographic and clinical characteristics of both cohorts was conducted.
Results:
Among the 4,074 adult patients included in the study, a total of 3,657 (89.8%) were male and 417 (10.2%) were female. In-hospital mortality occurred in 484 patients (11.9%). Adult patients admitted to the ICU exhibited a mortality rate 7.6-times higher than those who were not admitted (odds ratio [OR] = 7.6; 95% confidence interval [CI], 6.2–9.3). The analysis of the mREMS revealed a median score of eight for survivors and fourteen for non-survivors, demonstrating a statistically significant difference (P < .001).
Conclusion:
The present study demonstrated that the majority of civilians injured during the SCW were young males. Furthermore, this study’s findings indicated that the mREMS exhibits excellent performance in predicting in-hospital mortality among trauma patients injured during the SCW.
Yogurt acid whey (YAW) contains significant amounts of calcium as well as small amounts of protein, thus the idea of its reintroduction, especially of its calcium content, to the food chain is attractive. Calcium in milk is mainly complexed with casein micelles, whereas YAW contains only small amounts of protein, with no caseins at all, differing substantially from milk in the form in which calcium occurs. Therefore, the objective of the present research paper was to evaluate whether calcium bioavailability differs between YAW and milk. Following the INFOGEST protocol for simulated digestion and by coupling it with the Caco-2 model for intestinal absorption, calcium in YAW had higher bioaccessibility than calcium in milk. However, there were no differences in calcium transport by the intestinal cells and the transcription level of calcium absorption-related genes (VDR, TRPV6, S100G and PMCA1). Lastly, there were no differences in calcium bioaccessibility and the transcription of the calcium absorption-related genes between YAW samples of bovine, ovine or caprine origin obtained from Greek dairy products enterprises. In conclusion, despite the major differences in the protein profile between YAW and milk, there were no differences in calcium transport by the cells, but YAW was associated with higher calcium bioaccessibility, which ultimately may result in higher amount of absorbed calcium.
