Nucleation and phase transition of decagonal quasicrystals.

In this work, we study the nucleation of quasicrystals from liquid or periodic crystals by developing an efficient order-order phase transition algorithm, namely, the nullspace-preserving saddle search method. In particular, we focus on nucleation and phase transitions of the decagonal quasicrystal (DQC) based on the Lifshitz-Petrich model. We present the nucleation path of DQC from the liquid and demonstrate one- and two-stage transition paths between DQC and periodic crystals. We provide a perspective of the group-subgroup phase transition and nucleation rates to understand the nucleation and phase transition mechanisms involving DQC. These results reveal the one-step and multi-step modes of symmetry breaking or recovery in the phase transition from DQC, where the multi-step modes are more probable.

Pseudo-Scientist: Towards Narrative Interventions for Imposter Syndrome

Imposter syndrome (IS) is a mental state that can severely inhibit a person's productivity and well-being. Although IS is extremely common (especially in high achievers, e.g., academics), few studies offer effective modes of support and recovery. In response, we introduce the application of relatable narrative as a way to help people overcome IS. We present a randomized group comparison study exploring the impact of various design factors -- specifically, choice-based interactivity and character relatability -- on our story's capacity to engage and impact 107 STEM undergraduates. Almost all participants enthusiastically endorsed the story as a valuable learning experience, and a majority reported positive impacts to mood and feelings of relatedness to peers. We discuss 1) how our specific digital story design can support positive changes in mental health at both individual and institutional levels and 2) how our findings can inform efficient design of interactive narrative content for educational applications.

A multi-dimensional framework for assessing disaster recovery pathways: Lessons and experiences from Germany and Nigeria

The recent global surge in extreme events is escalating, leading to intensified impacts on lives, livelihoods, and overall well-being with long-lasting effects. As a result, communities in exposed regions with limited adaptive capacity find themselves in modes of constant recovery. However, disaster recovery is often treated as a secondary concern within global disaster risk reduction policies and practices. Previous studies have primarily focused on recovering people, places, and processes, neglecting a comprehensive examination of the relationships between actors, institutions, and decision-making across different time horizons. This paper aims to address this gap by introducing the concept of disaster recovery pathways and presenting a multidimensional framework for assessing these pathways. The framework comprises four interconnected components: systems, community capacity, actors relationships, and institutions. To develop this framework, we first review existing frameworks on disaster recovery and identify their limitations. We then apply the new framework to Ahr Valley in Germany and Lagos in Nigeria through policy document analysis and in-depth interviews with stakeholders. Our findings reveal that both countries face challenges in achieving a truly sustainable and resilient recovery. Financial constraints, political polarization, and administrative factors often serve as barriers to "build back better," and immediate relief and reconstruction efforts frequently prioritize innovative and sustainable practices in the recovery process. Our findings underscore the importance of collaboration, trust, and communication among stakeholders in driving effective recovery pathways efforts. We conclude that disaster recovery pathways encompass not only the reconstruction of physical infrastructure but also social, economic, psychological, environmental, and governance dimensions.

‘Volviendo a Vivir’ (coming back to life): Urban trauma, activism and building emancipatory futures

This paper engages recent writing on urban trauma, exploring its connection with the gendered forms of activism that displaced women practise as they seek to rebuild more emancipatory urban futures. Their activisms are situated in the context of multiple, ongoing and intersecting forms of violence from intimates, armed groups and the state, including institutional neglect (in and of the city) that is racialised and gendered. We draw on participatory action research undertaken with women in the Colombian cities of Bogotá and Medellín. Using creative audio-visual methods over several months, women co-researchers produced a documentary in which they chart the ways that they claim spaces of the city inside and outside their homes. We draw particular attention here to the temporal dimension of urban trauma as it intersects with migrant women’s spatial biographies; this has consequences for their activisms which also transcend the sites and scales of public and private spheres, national and global crises and individual and community responses. We argue that it is the gradually accruing and multiplying character of violence and trauma which in turn necessitates the gradual and multiscalar development of these activisms. The women used ecological metaphors of rooting and growth to explain how, through these activisms and directly informed by past traumatic events, they ‘come back to life’. Together, they build solidarity networks and alliances, and imagine and practise alternative feminist urban futures and modes of recovery in their new urban homes.

The colonial archive and its fictions

ABSTRACT The archive has played a crucial role in art historical scholarship in helping to flesh out the identities of colonial artists, scribes, and writers. But the vagaries of history, colonialist violences, and postcolonial regimes mean that the archives undergirding such study are particularly unstable. This essay treats the role of archives (their lacunae as well as their surpluses) in shaping the historical methods and scholarly desires around these actors. Case studies are organized around objects made of ink and paper, the same materials as colonial documentation. These cases span a wide temporal range, a broad geographic frame, and a diverse set of period actors. Set out in reverse chronological order, they capture the longing and lament that colonial archives produce. The essay then turns to archival gaps that have been or might be filled, focalizing a range or methods—from historically sanctioned modes of recovery to patently fraudulent fictions—to explore generative methods of probing archival limits.

The mechanism study on the integrated process of NaOH treatment and citric acid leaching for rare earth elements recovery from coal fly ash

Rare earth elements and yttrium (REY) have vital functions in the global economy because of their numerous applications. Coal fly ash (CFA) is considered a potential alternative resource for REY. In this paper, sequential chemical extraction procedure, NaOH treatment, and citric acid leaching were used to study modes of occurrence, enrichment, and recovery of REY in CFA after physical separation. The proportion of REY (84%) bond to aluminosilicate phase in the separated sample is higher than that in the raw CFA. Monazite, apatite, scheelite, and aluminosilicate phase were proved to be REY carriers via SEM-EDS observation. REY in CFA was enrichment by NaOH treatment, and the glassy phase dissolution conformed to shrinking core model. The dissolution was first controlled by a chemical reaction and then inner diffusion, with activation energies of 70.89 and 3.21 kJ/mol and reaction orders of 1.02 and 0.73, respectively. The gel conjunction and zeolite generation limited CFA dissolution, concluded from the chemical reaction verification, SEM observation, and XRD analysis. The REY content after multi-step NaOH treatment increased to 2135 μg/g with an enriched factor of 2.08. Citric acid (0.05 mol/L) leaching was investigated and REY recovery is 55%. A conceptual integrated process of NaOH treatment and citric acid leaching for the CFA utilization was designed. This paper will provide a theoretical fundamental and technological support for REY recovery.

Experimental Investigation of the Synergistic Effect of Two Nonionic Surfactants on Interfacial Properties and Their Application in Enhanced Oil Recovery.

In chemically enhanced oil recovery (EOR), surfactants are conventionally used to lower the interfacial tension (IFT) at the water-oil interface, alter the rock wettability, and help in the emulsification of trapped oil after primary and secondary modes of recovery. A mixture of surfactants is usually more effective than a single surfactant with enhanced surface or interfacial properties. The primary objective of this study is to examine the synergistic effects of two nonionic surfactants (Tergitol 15-S-12 and PEG 600) on surface properties, such as surface tension, IFT, and wettability alteration, in the context of EOR. The optimum composition of the surfactant mixture was obtained by surface tension measurement, and it has been found that the Tergitol 15-S-12 and PEG 600 mixture shows better synergistic effect with a minimum surface tension value of 30.3 mN/m at 225 ppm concentration of Tergitol 15-S-12 and 1 wt % of PEG 600. The surfactant mixture with optimum composition shows an ultra-low IFT of 0.672 mN/m at optimum salinity. The wettability alteration study was conducted in a goniometer by observing the change of the contact angle of an oil-wet sandstone rock in the presence of the formulated chemical slugs at different concentrations, and the results show a shift in the wettability of rock from the oil-wet to the water-wet region. The wettability alteration behavior of oil-wet rock is established using X-ray diffraction analysis of sandstone rock and zeta potential measurements of the chemical slugs. The efficacy of the optimized chemical slug for EOR was checked by a core flooding experiment, and an additional recovery of 17.73% of the original oil in place was observed.

Post-fire regeneration of cork oak (Quercus suber) in Kiadi forest (Akfadou- Algeria)

Cork oak (Quercus suber) as a West Mediterranean species is known for its ecological, economic and social values. Wildfires are one of the most serious problems threatening Quercus suber, endangering its occurrence in its area of distribution. Therefore, knowing the behavior of the species after fire and the factors influencing its responses are particularly important for forest management. In this study we assessed the post fire vegetative recovery in 730 trees affected by wildfires on 2014 in Kiadi cork oak forest, located in the Western side of Akfadou Mountains in Algeria. Few months after the fire, individual tree mortality was very low (7.53%), and nearly, all the trees sampled survived the fire since almost all trees resprouted from canopy and some of them showed basal resprouts. Moreover, those two modes of post fire vegetative recovery were not correlated to each other. The performed redundancy analyzes (RDA) revealed that the cork oak post-fire response was highly correlated with individual characteristics and with the environmental data. The main variables influencing the likelihood of good or poor vegetative recovery were the understory height and cover, soil characteristics, fire severity, tree status (alive/dead trees), tree diameter and tree exploitation. Our results confirmed the fire resistance of cork oak species; which is also the only Algerian tree to resprouts. Hence, this makes the species a good candidate for reforestation programs in fire prone ecosystems.

How different COVID-19 recovery paths affect human health, environmental sustainability, and food affordability: a modelling study

BackgroundThe COVID-19 pandemic arrived at a time of faltering global poverty reduction and increasing levels of diet-related diseases, both of which have a strong link to poor outcomes for those with COVID-19. Governments responded to the pandemic by placing unprecedented restrictions on internal and external movements, which have resulted in an economic contraction. In response to the economic shock, G20 governments have committed to providing US$14 trillion stimuli to support economic recovery. We aimed to assess the impact of different COVID-19 recovery paths on human health, environmental sustainability, and food sustainability.MethodsWe used LandSyMM, a global gridded land use change model, to analyse the impact of recovery paths from COVID-19. The paths were illustrated by four scenarios that represent different pandemic severities (including a single or recurrent pandemic) and alternate modes of recovery, including a transition of food demand towards healthier diets that result in changes to the food system: (1) solidarity and celery, (2) nothing new, (3) fries and fragmentation, and (4) best laid plans. For each scenario, we modelled the economic shocks of the pandemic and the impact of policy measures to promote healthier diets in the years after the COVID-19 pandemic, including the supply of and demand for food, environmental outcomes, and human health outcomes. The four scenarios use established future population growth and economic development projections derived from the Shared Socioeconomic Pathways 2. We quantified the outcomes from more societally cooperative pandemic responses that result in reduced trade barriers and improved technological development against less cooperative responses.FindingsRepeated pandemic shocks (the fries and fragmentation and best laid plans scenarios) reduce the ability of the lowest income countries to ensure food security. A post-pandemic recovery that includes dietary transition towards the consumption of less meat and more fruits and vegetables (the solidarity and celery scenario) could prevent 2583 premature deaths per million in 2060, whereas recovery paths that are focused on economic recovery (the fries and fragmentation scenario) could trigger an additional 778 deaths per million in 2060. The transition of dietary preferences towards healthier diets (the solidarity and celery scenario) also reduces nitrogen fertiliser use by 40 million tonnes and irrigation water by 400 km3 compared with no dietary change in 2060 (the nothing new scenario). Finally, the scenario with dietary transition increases the affordability of the average diet.InterpretationThe economic impact of the COVID-19 pandemic is most visible in low-income countries, where a reduction in growth projections makes a greater difference to the affordability of a basic diet. A change in dietary preferences is most impactful in reducing mortality and the burden of disease when income levels are high. At lower income, a transition towards lower meat consumption reduces undernourishment and diet-related mortality.FundingThe Global Food Security's Resilience of the UK Food System Programme project, with support from the Biotechnology and Biological Sciences Research Council, Economic and Social Research Council, Natural Environment Research Council, and the Scottish Government.

The Renunciation of One’s Nationality of Origin and European Union Citizenship: is it Compatible with Spain’s Dual Nationality System?

As a basic principle of international law, the ways of the different modes of nationality acquisition, recovery and loss is a matter falling under the jurisdiction of sovereign nations. However, as with other issues, relatively unrestricted intra-EU mobility rules have spawned a debate on the compatibility between national regulations and the demands of the current European status civitatis. In this study, considering the increasingly common factual and legal phenomenon of plurinationality, we will question the existing requirement in some systems of nationality law (among them Spain’s) for one to expressly renounce their nationality of origin when aspiring to be naturalized through residence in another Member State. In the current stage of the development of European integration process, this demand for renunciation becomes an unsustainable demand. In fact, avoid the legal recognition and enjoyment of two European nationality obstructs the full respect for own personal and plural identity as European citizenship. Implementing the procedures towards a paradigm shift are as needed as possible, which is explored in this study.

A Psychoanalytical Approach of Body Memory in Asian Literature

This paper investigates the concept of body memory treated in Shauna Singh Baldwin’s <i>What the Body Remembers</i>. It deals not only with revealing the potential methods of remembering, but also how victims resort to alternative modes of memory and recovery. The late twentieth century has witnessed an increased emphasis on questions of memory as the generations which experienced the atrocities of the two world wars die out, and new or revived national movements build their demands on memories of oppression or trauma. Adopting a non-verbal source of inquiry, Shauna Singh Baldwin questions the unchallenged supremacy of the verbal testimony as a means for healing the self, emphasizing how South Asian Literary Texts themselves point toward non-textual sites of memory such as human body. Baldwin explores the dark tunnels of memory in which the revelation of the past occurs brilliantly through new generatively trans-textual intersections of memory, nationalism and narrative Scars, tattoos, post-memory, and reincarnation are among the new modes presented by this Indian author. In this vein, I claim that the text comes out to suggest new ways in which human body can preserve and displays individual and collective memory. I shall also discuss the extent to which the female body potentially facilitate the act of remembering denying the importance of the language structure.

The modes and competing rates of cartilage fluid loss and recovery

Cartilage loses, recovers, and maintains its thickness, hydration, and biomechanical functions based on competing rates of fluid loss and recovery under varying joint-use conditions. While the mechanics and implications of load-induced fluid loss have been studied extensively, those of fluid recovery have not. This study isolates, quantifies, and compares rates of cartilage recovery from three known modes: (1) passive swelling – fluid recovery within a static unloaded contact area; (2) free swelling – unrestricted fluid recovery by an exposed surface; (3) tribological rehydration – fluid recovery within a loaded contact area during sliding. Following static loading of adult bovine articular cartilage to between 100 and 500 μm of compression, passive swelling, free swelling, and tribological rehydration exhibited average rates of 0.11 ± 0.04, 0.71 ± 0.15, and 0.63 ± 0.22 μm/s, respectively, over the first 100 s of recovery; for comparison, the mean exudation rate just prior to sliding was 0.06 ± 0.04 μm/s. For this range of compressions, we detected no significant difference between free swelling and tribological rehydration rates. However, free swelling and tribological rehydration rates, those associated with joint articulation, were ∼7-fold faster than passive swelling rates. While previous studies show how joint articulation prevents fluid loss indefinitely, this study shows that joint articulation reverses fluid loss following static loading at >10-fold the preceding exudation rate. These competitive recovery rates suggest that joint space and function may be best maintained throughout an otherwise sedentary day using brief but regular physical activity. Statement of SignificanceCartilage loses, recovers, and maintains its thickness, hydration, and biomechanical functions based on competing rates of fluid loss and recovery under varying joint-use conditions. While load-induced fluid loss is extremely well studied, this is the first to define the competing modes of fluid recovery and to quantify their rates. The results show that the fluid recovery modes associated with joint articulation are 10-fold faster than exudation during static loading and passive swelling during static unloading. The results suggest that joint space and function are best maintained throughout an otherwise sedentary day using brief but regular physical activities.

Energy and exergy analysis of the zinc/zinc oxide thermochemical cycle for hydrogen production and fuel cell power generation

Water-splitting thermochemical cycles have emerged as a possible solution for the decentralized production of hydrogen using solar energy. A useful tool to select the most promising thermochemical cycles among those proposed in the literature is represented by the exergy analysis. In this context, the exergy and energy analyses of the zinc/zinc oxide thermochemical water-splitting cycle, coupled with the production of electrical energy in a fuel cell, are here carried out and discussed. The aim has been to identify the steps in the process characterized by the highest inefficiencies and to propose possible solutions to increase the overall thermodynamic efficiency. Calculations were carried out using the commercial process simulator PRO/II. The cycle consists of two steps: (i) the endothermic thermal reduction of solid zinc oxide to liquid zinc and oxygen, carried out in a solar thermo-reactor at 2025 °C, and (ii) the non-solar, exothermic hydrolysis of zinc to form hydrogen and solid zinc oxide. This work reports three possible process schemes based on the zinc/zinc oxide redox reactions, each differing from the others in terms of envisaged modes of heat recovery. In addition, the effect of carrying out the hydrolysis step under adiabatic, rather than isothermal conditions, has been analysed. Four values of conversion were considered (1, 0.9. 0.8, and 0.7) and the effect on fuel cell power generation, utility consumption, and energy and exergy efficiency was evaluated. It was found that the exergy efficiency increased from about 14% for the classical zinc/zinc oxide cycle to almost 40% in the most efficient scenario considered here. The variation of hydrogen conversion in the fuel cell led to a decrease in generated power, from 16.41 MW at hydrogen conversion of 1 down to 11.48 MW at hydrogen conversion of 0.7.

Stress Fracture in Non-Athletes: A Systematic Review

&#x0D; The present study seeks to discuss the incidence of a stress fracture in not athletes. This type of pathology occurs as a result of a repetitive number of movements in a given region, fatigue and muscle imbalance are the main responsible for these fractures, which mainly affect runners and military, groups that are more susceptible to a large amount of impact In practice, and has been increasing in non-athletes. To do so, it reviews the literature based on the first descriptions of the stress fracture, the causes of this type of occurrence, the results on the patient's body, and the modes of treatment and recovery. The objective of this study is to review the literature currently available to aggregate the most relevant information regarding this pathology.&#x0D;

Electrolytic alloying of iron-chromium during deposition of coatings from a sulfate-chloride electrolyte

The paper presents the results of studies of the process of electroreduction of alloy iron-chromium from a sulfate-chloride electrolyte, influence of electrolyte composition and electrolysis (acidity, electrolyte temperature and cathode current density) on the process kinetics, the output of the alloy current efficiency and physico-mechanical properties of the coatings (microhardness, morphology). There were determined such parameters as the optimal ratio of concentrations of electrolyte components – 150 g/l of iron chloride (2) and 50 g/l of chromium sulfate (3) and modes of electrical recovery of metals – current density 40 A/dm2; the temperature of the electrolyte is 50°C, the acidity of the solution is 0.5 pH units, which contribute to obtaining a high-quality coating with high tribological characteristics. Assumptions are made about the mechanism of the alloy formation by electrolysis from a mixed electrolyte.

Entrepreneurial learning from failure. A systematic review

PurposeFailure plays a pivotal role in entrepreneurial learning. Knowledge of the learning process that enables an entrepreneur to re-emerge stronger after a failure, though considerable, is fragmented. This paper systematically collects relevant literature, assigns it to the stages of the experiential learning process (concrete experience, reflective observation, abstract conceptualization, active experimentation; Kolb, 1984), evaluates the research coverage of each stage and identifies promising avenues for future research.Design/methodology/approachThis systematic literature review follows the guidelines articulated by Short (2009) and Tranfield et al. (2003), using Web of Science and EBSCO as primary data sources. Kolb’s (1984) experiential learning theory provides a basis for organizing the identified material into a framework of entrepreneurial learning from failure.FindingsThe literature provides insights on all stages of the process of entrepreneurial learning from failure. Particularly well elaborated are the nature of failure and its triggering effect for reflection, the factors influencing reflection, the contents of the resulting learning and their application in entrepreneurial re-emergence. Other topics remain under-researched, including alternative modes of recovery, the impact of personal attributes upon reflection, the cognitive processes underlying reflection, the transformation of failure-based observations into logically sound concepts and the application of this learning in non-entrepreneurial contexts.Originality/valueThis review provides the most complete overview of research into the process of entrepreneurial learning from failure. The systematic, theory-based mapping of this literature takes stock of current knowledge and proposes areas for future research.

On the Competition between Two Modes of Product Recovery: Remanufacturing and Refurbishing

The markets for recovered products in China typically consist of both remanufactured and refurbished products. The government requires that the remanufactured product match the quality level of the new product, while no such requirements exist for the refurbished product. Furthermore, remanufacturing is a relatively new phenomenon in China, whereas the refurbishing industry is old, widespread, and largely unregulated. Compared to the new product, the two types of recovered products enjoy a cost advantage, but they suffer from a lower willingness‐to‐pay in the consumer market. These observations lead to a game‐theoretic model consisting of three players: an original equipment manufacturer (OEM) providing the new product, a remanufacturing firm, and a refurbishing firm. The goal is to understand what equilibrium market structure may arise and how the equilibrium outcome depends on some of the key model parameters. It is found that (1) the entry barrier for the remanufacturer is always higher than that for the refurbisher; (2) remanufacturing almost always reduces the environmental and social (E/S) impact of the secondary market (for spare parts), such as the consumption of raw materials and energy during parts production, emissions and safety concerns during product use, and the E/S impact incurred during product disposal; and (3) the OEM has a natural tendency to discourage any form of product recovery by a third party, refurbishing or remanufacturing. These findings have potential policy implications for the government’s effort in cultivating the remanufacturing industry.

Lake eutrophication recovery trajectories: Some recent findings and challenges ahead

Abstract Controlling nutrient inputs has allowed many lakes and several river, estuarine and coastal ecosystems to recover rapidly from eutrophication. In some systems, however, recovery has been slow or negligible. The broad changes in environmental conditions could in many cases be responsible for the observed delays in recovery. We proposed three basic scenarios and seven different trajectory modes of lake eutrophication recovery. Monitoring data from six lake ecosystems were analyzed to study the relationships between chlorophyll a and nutrients and their applicability in lake management. The combination of seven basic tracks can make decisions on the whole space, it will provide a visual management tool for governance decisions on specific lakes, avoiding the waste caused by blind pollution control measures with unclear objectives and inefficient methods. We believe that timely “artificial hand” adjustment measures in coordination with proper implementation can ensure that lakes have a greater chance of achieving a right-lateral repair pathway for the continuous control of phosphorus inputs and that the use of “natural hand” measures may help shorten the recovery time.
