PROSPECTS OF THE IMPLEMENTATION OF THE METHOD OF NONVIOLENT COMMUNICATION IN SOCIAL WORK IN UKRAINE DURING THE WAR AND POST-WAR RECOVERY
Authors: MALOVICHKO Olena , MASYUK Oleg , GUESSAB Karim , BILOKOPYTOVA BILOKOPYTOVA
Published: August 2024

The team of authors conducted systematic work on the analysis of the use of the method of nonviolent communication in various areas of social work in Ukraine and other countries of the world. During the research, the team of authors relied on a comprehensive approach, comparative analysis, and a focus group study was conducted, which revealed the need to transform the social service system in this area.
The purpose of the research work is to analyze the prospects for the effective implementation of the nonviolent communication method in social work in Ukraine during the war and post-war reconstruction. We drew attention to the increase in various manifestations of violence in Ukraine during the war, which was reflected in the actualization of the issue of bullying in educational institutions, cases of violence in the family, and in the increase in violent crimes in society as a whole.
In our opinion, the method of nonviolent communication is useful for a social worker in working with an aggressor and a victim, as it contains a powerful ethical and pedagogical component. As a result, we concluded that Ukraine needs a restructuring of the social service system, which contributed to solving the problems of the population in the country. The basis for the optimization of social services should be a review of standards in the field of education and pedagogy, a non-violent rethinking of the relationship «social worker - recipient of social services», as well as the restart of the judicial and social service.
Based on the conducted research, we conclude that the implementation of the method of nonviolent communication in social work in Ukraine has many obstacles of a military-political, socio-state and organizational nature, but changes in the social sphere in Ukraine are needed now. In fact, this is the need for radical changes in social work with manifestations of violence, as well as the need for partnership work to restore a humanistic and non-violent space in Ukraine, starting with the family. Here the family acts as a basis for post-war social recovery.
Quantum Networks: A New Platform for Aerospace
Authors: Brickman Soderberg Kathy-Anne , Gauthier Daniel J. , Kwiat Paul G. , Srinivas Raghavendra
Published: August 2024

The ability to distribute entanglement between quantum nodes may unlock new capabilities in the future that include teleporting information across multinode networks, higher resolution detection via entangled sensor arrays, and measurements beyond the quantum limit enabled by networked atomic clocks. These new quantum networks also hold promise for the Aerospace community in areas such as deep space exploration, improved satellite communication, and synchronizing drone swarms. Although exciting, these applications are a long way off from providing a “real-world” benefit, as they have only been theoretically explored or demonstrated in small-scale experiments. An outstanding challenge is to identify near-term use cases for quantum networks; this may be an intriguing new area of interest for the aerospace community, as the quantum networking field would benefit from more multidisciplinary collaborations. This paper introduces quantum networking, discusses the difficulties in distributing entanglement within these networks, highlights recent progress toward this endeavor, and features two current case studies on mobile quantum nodes and an entangled clock network, both of which are relevant to the aerospace community.
Lifting of Transversely Forced Turbulent Nonpremixed Coaxial Jet Flames
Authors: Plascencia Miguel A. , Talley Douglas G. , Roa Mario , Karagozian Ann R. , Munipalli Ramakanth
Published: August 2024

The lifting behavior of turbulent nonpremixed coaxial jet flames was investigated experimentally as a function of the center jet Reynolds number, annular-to-center jet velocity ratio, acoustic frequency, and acoustic amplitude, all with and without transverse acoustic disturbances acting on the flames situated at a pressure antinode. Global lifting regimes were mapped and consisted of attached flames, periodically lifted flames, and permanently lifted flames. With one exception, all flames were attached in the absence of acoustics and lifted only because of the applied acoustic excitation. The exception occurred at the highest Reynolds number and velocity ratio, where the flames were unconditionally lifted in all cases. Between these two extremes, a range of lifting regimes was observed. Lower applied frequencies and smaller amplitudes were found to generally promote attachment to the burner. Flow visualizations using high-speed Schlieren and [Formula: see text] chemiluminescence imaging revealed a lateral spreading effect near the jet exit. The lateral spreading was hypothesized to be caused by an axially oriented counterflow collision between the downstream flowing jets and presumed local upstream portion of the acoustic velocity fluctuations. Physical mechanisms were hypothesized based on this observation, which appear to consistently explain most of the observed behavior.
Implementation and Linearization of a Coupled Panel and Vortex Particle Method in State-Space Form
Authors: Hussien Hussien A. A. H. , Cocco Alessandro , Saetti Umberto
Published: August 2024

This paper describes the implementation and linearization of a coupled panel and vortex particle method in a state-variable form. More specifically, the coupled panel and vortex particle dynamics are formulated as a nonlinear system of ordinary differential equations in first-order form to be self-contained and inherently linearizable. Linearization of this coupled panel and vortex particle method is demonstrated via finite differencing and a novel analytical linearization technique to yield a linear time-invariant representation. The code is implemented in MATLAB® and validated against an open-source aerodynamic solver for a fixed wing in both stationary and unsteady conditions. The linearized models are verified against the nonlinear dynamics both in the time and frequency domains. Linearized models accurately represent the wake dynamics about the equilibrium condition for moderate amplitude inputs and for input frequencies covering the typical frequency range of flight dynamics and flight controls, i.e., 0.3–30 rad/s. Analytical linearization is shown to abate the cost of linearization over perturbation methods by [Formula: see text], where [Formula: see text] is the total number of states of the system. Linearized models of the coupled panel and vortex particle dynamics have applications in the flight dynamics of both fixed- and rotary-wing vehicles, where these dynamics can be used to augment the rigid-body dynamics. The coupled rigid-body and wake dynamics can be leveraged to assess the stability, response characteristics, and handling qualities of vehicles experiencing aerodynamic interactions between rotors, wings, and/or obstacles.
Scaling Laws for Deployable Mesh Reflector Antennas
Authors: Suh Jong-Eun , Dassanayake Sahangi P. , Thomson Mark W. , Pellegrino Sergio
Published: August 2024

This paper begins with the formulation of a general, rapid design method for deployable mesh reflector antennas based on the AstroMesh architecture. This method is then used to obtain estimates of the total mass, stowed envelope size, and fundamental natural frequency of vibration for antennas with a range of aperture diameters and focal lengths, assuming an operational radio frequency of 10 GHz. A study of the scaling trends of this reflector design shows that the distribution of prestress in the inner tension structure has a major impact on the mass of the outer perimeter truss. Based on this result, a prestress optimization problem to design reflectors of minimum mass is formulated, and analytical scaling laws are obtained for the mass, stowed envelope, and natural frequency of optimally prestressed reflectors with aperture diameters up to 200 m. It is then shown that aperture diameters of 70–100 m are at the limit of launchers that are currently available or under development. A semianalytical homogenization model that accurately estimates the fundamental natural frequencies for batten-supported and free-free boundary conditions is also presented.
Effect of Tripping and Domain Width on Transonic Buffet on Periodic NASA-CRM Airfoils
Authors: Lusher David J. , Sansica Andrea , Hashimoto Atsushi
Published: August 2024

Transonic buffet is an instability characterized by shock oscillations and separated boundary layers. High-fidelity simulations have typically been limited to narrow domains to be computationally feasible, overly constraining the flow and introducing modeling errors. Depending on the boundary-layer state upstream of the interaction, different buffet features are observed. High-fidelity simulations (implicit large-eddy simulation) were performed on the periodic (infinite) NASA-CRM wing at a moderate Reynolds number to assess the sensitivity of the two-dimensional transonic buffet to boundary-layer state and domain width. Simulations were cross-validated against low-fidelity Reynolds-averaged Navier–Stokes (RANS)/unsteady RANS and global stability analysis, and excellent agreement was found near the onset. By varying the boundary-layer tripping amplitude, laminar, transitional, and turbulent buffet interactions were obtained. All cases consisted of a single shock and low-frequency oscillations [Formula: see text]. The transitional interaction also exhibited reduced shock movement, a 15% increase in [Formula: see text], and energy content at higher frequencies [Formula: see text]. Spanwise domain studies showed sensitivity at the shock location and near the trailing edge. We conclude that the span width must be greater than the trailing-edge boundary-layer thickness to obtain span-independent solutions. For largely separated cases, the sensitivity to span width increased, and variations across the span were observed. This was found to be associated with a loss of two-dimensionality in the flow.

Monitoring the three-dimensional formation of ice layers on airfoils during icing wind tunnel experiments is extremely challenging. For the first time, this paper demonstrates the use of a single plenoptic camera to perform transient, nonintrusive in situ measurements of ice crystal accretion. Experiments have been conducted in the Altitude Icing Wind Tunnel at the National Research Council of Canada under different icing conditions to assess the potential of the new technique. Using the camera in a close-up configuration, the results show the evolution of the three-dimensional shape of the accreted ice in high spatial and temporal resolution and in absolute metric units. The computed surface meshes allow for a detailed analysis in terms of ice shape, surface area, and ice volume. Posttest shapes are compared to measurements taken using a commercial laser scanner. Although not rated for ice surfaces, this device is used as a reference to compare the detailed surface structure after registering the data sets. The results of the two methods are in good agreement and show a mean relative deviation of the plenoptic camera of about 0.15 mm.
The UK’s Nationality and Borders Bill Policy: Its Impact on Refugees and Asylum Seekers
Authors: Nkwe Selemo
Published: August 2024

The United Kingdom (UK) introduced the Nationality and Borders Bill (2021) to address illegal immigration. This article argues that the UK’s historical asylum policies have contributed to marginalising asylum seekers through a process of “othering.” It demonstrates how policy language and symbols, combined with media discourse, frame asylum seekers as security threats. The power dynamics among public officials and humanitarian agencies further legitimise refugees as the “other.” The article suggests a bottom-up approach involving civil society organisations to incorporate refugee voices in challenging dominant narratives and policymaking. By sharing refugee narratives, this article reveals that refugees are conscious of being marginalised and advocate for policy change. This approach not only empowers them but also helps expose existing stereotypes and power imbalances within mainstream immigration policies.
Afrocentric Visual Analysis of Online Political Posters: A Case of South Africa’s July 2021 Unrest

Published: August 2024

This article argues that the social media network X (formerly known as Twitter) is a public sphere that uses different rhetorical strategies of visual political communication to set a political agenda and shape public opinion about political issues in South Africa. Visual images in the context of political communication are used to inform, persuade, and create ideological meaning. They employ different visual rhetorical strategies to construct narratives about a political issue or actor. The article employs an Afrocentric perspective as a theoretical and research method to interrogate the underlying African visual rhetoric of online political posters (OPPs) circulated on X by members of the African National Congress (ANC) faction in the KwaZulu-Natal province during the July 2021 uprising. The units of analysis were verbal and visual texts featured in the selected OPPs. The findings showed that ANC members who identified with the radical economic transformation (RET) faction deployed various styles of Afrocentric visual rhetoric to oppose the far-right faction of the ANC. This article contributes to the body of research premised on Afrocentric visual rhetorical and visual political communication, which remains under-researched, particularly in the decolonial context.
Poisoning and Envenomation Induced Acute Kidney Injury: A Hospital-Based Study

Published: August 2024

Background

Most cases of acute kidney injury (AKI) in the Indian subcontinent are community-acquired. Some causes of AKI like poisonings are unique to the local demographics. This study examined the clinical features, spectrum, and outcomes of AKI in patients with poisoning and evaluated the predictors of mortality.

Materials and Methods

This was a prospective observational study conducted in patients admitted to Jawaharlal Nehru Medical College, Aligarh with an alleged history of poisoning orsnake bite. Relevant history, laboratory tests, mode of treatment, and outcome were recorded for all patients who were followed up after 3 months post discharge.

Results

During the study period, 394 patients were admitted with a provisional diagnosis of poisoning/snake bite analyzed, of whom 56 (14.2%) developed AKI. Final data analysis was done for 51 patients as 5 patients were lost to follow up. Paraquat poisoning was the most common cause of AKI, seen in 12 patients, followed by methanol in 9 patients. Hemodialysis was required in 29 (56.8%) patients. Complete recovery was seen in 33 (64.7%) patients, and 14 patients (27.5%) died during the acute phase of the illness. Late presentation to the hospital and presence of shock (mean arterial pressure <65 mmHg) on presentation were found to be associated with adverse outcomes (mortality/failure of return of renal function at 3 months). The most common cause of death was septic shock seen in 8 patients.

Conclusion

This study, which is probably the first from North India, highlights the fact that cases of poisoning/envenomation-related AKI contribute to a sizeable amount of morbidity/mortality.
