Framed by Wefulness Theory (WT; Nuru & Bruess, 2022), the present study explores the COVID-19 global pandemic as a context for examining relational struggle and strength during times of challenge. Analysis of in-depth, dyadic interviews with 54 couples who reflect a broad range of ethnic-racial compositions, partnership structures, sexual orientations, and ages rendered intelligible relational partners’ wefulness practices in situ. Results reveal four suprathemes: (a) cultivating relational consciousness, (b) negotiating wefulness amidst challenge, (c) accepting life on life’s terms, and (d) inviting challenge as opportunity for growth. Data reveal how relational partners engage in ritualized (re)commitments as multi-vocal practices of expressing and embracing the current pandemic moment. Data also evidenced WT is heuristically powerful in reconceptualizing and illuminating relational meaning- and sense-making.

This paper described new characterization methods and data to quantify the influence of solute atoms on grain boundary and sub-grain boundary mobilities in Al-Mn alloys with a view to their integration into recovery and recrystallization modelling. Detailed SEM measurements of grain boundary mobilities during recrystallization have been made by in-situ annealing experiments on cold deformed Al – 0.1 and 0.3wt.% Mn binary alloys. Stored energies are estimated from the sub-grain sizes and misorientations and the boundary velocities directly measured in the temperature range 200-450°C. It is shown that in many cases good agreement with the Cahn, Lücke, Stüwe model for solute drag is obtained, e.g. the activation energies are intermediate between those of boundary and volume solute diffusion. Some particular cases of rapid growth occur in Al-0.1%Mn indicating boundary breakaway from solute clouds. A complementary study of sub-grain boundary mobilities has started on the same alloys; in this case the average mobilities are estimated from FEG-SEM growth data for the average sub-grain size for temperatures in the range 150-300°C. The results are compared with some previous data on Al- Si and show similar rates.

Abstract The first cases of Covid-19 in Iran were reported shortly after the disease outbreak in Wuhan, China. The end of the Persian year and the beginning of the Nowruz holidays in the following year (March 2020) coincided with its global pandemic, which led to quarantine and lockdown in the country. Many studies have shown that with the spread of this disease and the decline of industrial activities, environmental pollutants were drastically reduced. Among these pollutants, Nitrogen Dioxide (NO2) and Carbon Monoxide (CO) are widely caused by anthropogenic and industrial activities. In this study, the changes of these pollutants in Iran and its four metropolises (i.e., Tehran, Mashhad, Isfahan, and Tabriz) in three time periods from March 11 to April 8 of 2019, 2020, and 2021 were investigated. To this end, time-series of the Sentinel-5P TROPOMI and in-situ data within the Google Earth Engine (GEE) cloud-based platform were employed. It was observed that the results obtained from the satellite data were in agreement with the in-situ data (average correlation coefficient = 0.7). Moreover, the results showed that the concentration of NO2 and CO pollutants in 2020 (the first year of the Covid-19 pandemic) was 5% lower than in 2019, indicating the observance of quarantine rules as well as people’s initial fear of the Coronavirus. Contrarily, these pollutants in 2021 (the second year of the Covid-19 pandemic) were higher than those in 2020 by 5%, which could be due to high vehicle traffic and the lack of serious policy and law-making by the government to ban urban and interurban traffic. Furthermore, the increase of the NO2 and CO in 2021 was followed by an increase in the deaths caused by Covid-19 and triggering the fourth peak in the Covid-19 cases, signifying a link between exposure to air pollution and Covid-19 mortality in Iran.

This paper examines the potential of convergence technologies in the process of 9/11 memorialization, particularly when materiality and its absence are so crucial to the in-situ narrative of post terror attack. Questions over the incorporation of virtual and digital media are not new in the context of COVID-19 but are perhaps more urgent than ever, as we all begin to grapple with the turn to technology as a surrogate for what we cannot physically provide. In particular, I trace the Derridean phenomenon of autoimmunity to draw parallels between memorial practices associated with both 9/11 and COVID-19. Ultimately, the migration online initiated by global pandemic reminds us that traumatic memory in particular is punctuated by gaps and absences; it insists on the recognition of other, stranger, incomplete and imperfect ways of knowing and commemorating.

Abstract Background Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2 and broke out as a global pandemic in late 2019. The acidic pH environment of endosomes is believed to be essential for SARS-CoV-2 to be able to enter cells and begin replication. However, the clinical use of endosomal acidification inhibitors, typically chloroquine, has been controversial with this respect. Methods In this study, RT-qPCR method was used to detect the SARS-CoV-2N gene to evaluate viral replication. The CCK-8 assay was also used to evaluate the cytotoxic effect of SARS-CoV-2. In situ hybridization was used to examine the distribution of the SARS-CoV-2 gene in lung tissues. Hematoxylin and eosin staining was also used to evaluate virus-associated pathological changes in lung tissues. Results In this study, analysis showed that endosomal acidification inhibitors, including chloroquine, bafilomycin A1 and NH4CL, significantly reduced the viral yields of SARS-CoV-2 in Vero E6, Huh-7 and 293T-ACE2 cells. Chloroquine and bafilomycin A1 also improved the viability and proliferation of Vero E6 cells after SARS-CoV-2 infection. Moreover, in the hACE2 transgenic mice model of SARS-CoV-2 infection, chloroquine and bafilomycin A1 reduced viral replication in lung tissues and alleviated viral pneumonia with reduced inflammatory exudation and infiltration in peribronchiolar and perivascular tissues, as well as improved structures of alveolar septum and pulmonary alveoli. Conclusions Our research investigated the antiviral effects of endosomal acidification inhibitors against SARS-CoV-2 in several infection models and provides an experimental basis for further mechanistic studies and drug development.

New technologies of reintroduction of plant species presuppose implementing both traditional and biotechnological methods for obtaining certain planting materials. However, plants cultivated in vitro exist in specific conditions that lead to changes in their structural and functional state. This explains why it is hard for them to adapt to ex vitro and in situ conditions. Therefore, there is a need for the development of a multistage method of cultivating in vitro plants that would make the influence on their adaptive mechanism in ex vitro and in situ conditions possible. One of its stages is the optimization of the light regime of cultivation which can both initiate the change of the state of the photosynthetic apparatus of plants and increase their bioproductivity stimulating the work of their protective system. This work studies changes in the morphogenesis, growth data and pigment composition of the rare species of Gentiana lutea L. of three populations in the Ukrainian Carpathian (mountains Pozhyzhevska and Sheshul-Pavlyk, plateau Lemska) in vitro focusing particularly on the cultivation light regime. The research has proved the inefficiency of using fluorescent lamps of daylight lamps (LD) type as source of illumination because the low intensity of luminous flux in the area of photosynthetically active radiation (PAR), as well as high proportion of wavelength of blue (400–500 nm) and green (500–600 nm) range in the spectrum cause specific reactions of photomorphogenesis, which, despite the high content of pigments in plastids, lead to poor development of root systems, stretching the stems, formation of small leaves with thin leaflet plate, generally low productivity and low adaptive potential of G. lutea plants to ex vitro and in situ conditions. Complement of cold white light lamps to the fluorescent lamps LD type in the ratio of 1 : 1 enables one to increase the intensity of illumination in the field of PAR and raise the fraction of wavelength of red range (600–700 nm). Such light conditions both improve the bio-productivity of G. lutea plants of all three populations cultured in vitro in comparison to the LD type regimen, reducing the content of chlorophyll b and carotenoids in light-harvesting complexes of photosystems and facilitate an increase in the microclonal multiplication factor without using higher concentrations of exogenous growth regulators,which significantly reduces the cost of the process of obtaining planting materials. It was proved that a combination of LD type lamps, cold white light lamps and phytolamps in the ratio 1 : 1 : 0.6 should be used on the final stages of preparation of the planting material of G. lutea before transferring it to ex vitro and in situ conditions. This relates to the fact that the increase of the wavelength of the red range results in the widening of the active surface of the leaves, rise in the content of photosynthetic pigments, and the noticeable growth of the aboveground and underground parts of the plants. The article assumes that the use of such illumination mode will ensure a faster transition of cultured in vitro G. lutea plants from heterotrophic to autotrophic nutrition, improving their adaptive potential and enabling easier adaptation to non-sterile ex vitro and in situ conditions.

AbstractThe stories we tell about our identities and sexual orientations shape how we perform gendered scripts and negotiate relationships with significant others. Previous literature inquired the styles and outcomes of consensual non-monogamous (CNM) relationships, but more research is need on how CNM men resist or abide to hegemonic models of masculinity. To understand how constructions of masculinity and conceptualizations of sexual orientation are embedded in CNMs, the study analysed the stories of non-monogamous Bi+ and heterosexual men. Following a critical narrative approach, the study inquired the diverse conceptualizations of masculinity, sexual orientation and relationship practices in the narratives of 20 non-monogamous Bi+ and heterosexual identified men. The semi-structured in-depth narrative interviews (105 min on average) were analyzed via Nvivo 12 and explored their stories of desire and the sense-making process of being sexually oriented to one or more genders and to one or more partner/s. Engaging in non-monogamy was signified as a relevant insight from their personal stories and/or from adopting new concepts of desire beyond the “love as a zero-sum game.” The latter theme was also shared by many heterosexual participants that, when negotiating a non-monogamous agreement, signified their attractions to more than one person as part of their personal identity. Finally, the paper discusses how non-monogamous spaces can offer a positive and safe space for bisexuals/Bi+ people to explore and reaffirm their identities, constantly challenged by biphobia, invisibility, and erasure. Experiences and stories of Italian cisgender Bi+ and heterosexual men cannot be generalized to the whole spectrum of masculinities within CNM spaces, and the study lacks how other gendered and sexual subjectivities construct masculinity. Diverse stories and construction of sexuality and gender can lead to similar relationship preferences and understanding how we signify them can greatly improve our understanding of intimacies.

Haptic Learning

Abstract A central assumption within the embodied cognition paradigm is that particular action experiences are instrumental in providing children with sensorimotor contingencies that form the foundation for conceptualisation of and, later, communication of mathematical ideas. Digital technology designs that foster specific movements offer promising foundations for young children’s mathematical learning, together with haptic technologies that newly bring tactile sensorimotor experiences for children to draw on. This article reports on a qualitative study examining the role of a haptic learning environment supporting 7–8-year-old children’s embodied exploration of 3D shape. It examined the in situ dynamic unfolding of interaction of pairs of children, as they engaged with a haptic device. Multimodal analysis was focused on the process of how the prescribed enaction of the device-mediated interaction, the kinds of action experiences and action schemes it elicited and the strategies children collaboratively developed to complete tasks. Findings show how specific action experiences and, later, communication experiences, were shaped, not only by the prescribed enaction of the design, but also by embodied participatory sense-making, and demonstrate the potential for haptic technology in mediating new learning experiences for mathematics.

With the widening scope of design, the importance of the design studio has concomitantly responded by transforming its own character to become inclusive of the educational domains of history, professional practices, theories, technical, and material studies. The absorption of such domains, part-and-parcel of the studio setting, has irrevocably highlighted the importance of education within the container of the studio or rather ‘in-situ’ education. However, with the volatility of external factors, the challenges posed to design education are multiple. Especially in light of the rise of a global pandemic, educators globally have had to implement crisis strategies in response. This short visual essay outlines the obstacles of online teaching; moving from resistance to embracing the tools and features that online education provides. Sharing the gained experiences, starting at the rise of the pandemic, the text engages seven key points of interest, while practically demonstrating responses in the product design setting.
