Encoding Memory through Multimodality in Modern-Day Memorial Museums
Authors: Ghazaryan Grigor , Donatelle Steven 
Published: December 2022

The article is devoted to the use of technology in memorial museums, particularly in those related to genocide.
The authors use a multidisciplinary theoretical framework using a diverse toolkit from Semiotics, Communication Studies, and Philosophy to explain the benefits and dangers of implementing technology in a memorial museum. The framework makes particular use of Peirce’s idea of unlimited semiosis, Eco’s considerations about the multiplicity of meanings and the “open text”, the existence of not one but two narratives in museums—especially in memorial museums—and Heidegger’s writings on technology especially enframing and revealing which are invoked in order to explain the interplay between technology and memory.
Being based in Yerevan, Armenia, the authors formulate their ideas with the Armenian Genocide Museum Institute (AGMI) in mind. This results in practical recommendations of how technology could be implemented in modern-day memorial museums, and identifies the benefits and dangers that must be kept in mind when doing so.
The specific subject matter of the AGMI plays a part in how this discourse evolves and the framework is assembled through an exploration of the term genocide, the historical events and artifacts that are presented in the museum and the current setup of the museum.

Aims: The purpose of this paper is to assess the impact of climate change on crop production in the state in the year 2021.
Study Design: Cross-sectional survey design.
Place and Duration of Study: All the existing 34, Local Government Areas (LGAs) of Katsina State, and the research was conducted between October 2021 and March 2022.
Methodology: Data was gathered via questionnaires administered to farmers’, employing Village and Block Extension Agents’ as enumerators. A multi-stage sampling technique was employed. The first stage involved classifying the state into three ecological zones. The second stage comprises random selection of three villages from each 34 LGAs to give (102 villages). The third stage was accomplished, based on the lists of farmers (26,589) frame, obtained from Katsina State Agricultural and Rural Development Authority (KTARDA), twelve thousand (12,000) farmers were selected proportionately for the study, using systematic random sampling technique.
Results: The results indicated that male and youthful age dominate production respectively (78%) (54). large proportion (95%) fall within formal to post primary education and also, more than two-third (69) had no extension contact and highest (35%) obtained income from #300,001- #450,000. The findings on impact of climate change on crop production showed that (648,300 hectares) cultivated land and 633,950 tons (63,400 bags) of crops were lost. The analysis further unveiled that among the three ecological zones of the state, Sahel Savannah had the most devastating effect of losses, at both cultivated land (292,200 hectares) and crop yield (267,100 tons). More so, the result portrayed that amongst the assorted crops produced in the area, millet, groundnut, cowpea, and sorghum were the major crops affected by climate change scourge.

Aims: Afzelia africana is one of the most popular woody forage resources used by pastoralists in northern Cameroon in the dry season. In order to contribute to the sustainable management of this species in the Benoue National Park (BNP) and its surroundings, a study was conducted on the perception and conservation of this species, the knowledge of fodder ligneous by the riparian population of the BNP and adaptation to the drought of its seedlings.
Methodology: A survey was carried out in four surrounding villages of the BNP with 100 people per villages (Banda, Gamba, Sackdje and Guidjiba) making a total of 400 respondents. A hundred seedlings were monitored during two dry seasons and the mortality rate was calculated at the end of each dry season.
Results: This study determined the impact of drought on the survival of this species. The percentages of male respondents according to age group were 30%, 23%, 15%, 6% and 5% respectively for respondents whose age range was between 20-30 years, 10 and 20 years, 30- 40 years, 40 to 50 years and over 50 years. For the female sex these percentages are 10%, 5%,5% and 1% for the respective age groups of 10- 20 years, 20-30 years, 30-40 years and 40 to 50 years. On knowledge of A. africana, men have better knowledge with 80%; 74%; 70% and 64% respectively for Banda, Guidjiba, Gamba and Sackdje. On its conservation, 44% of the sample responded favorably. Sixteen forage trees belonging to 10 families were reported by the respondents, the Caesalpiniaceae family and the Mimosaceae family, were the most represented (nearly 18.75%). The average drought mortality rate was 20% after two droughts.
Conclusion: Such a study is a fundamental prerequisite for the development of restoration and sustainable management strategies for Afzelia africana in the Bénoué National Park (North Cameroon).

Abstract
Roadsides are targeted for restoration of pollinator‐friendly plants. Yet, roads are sources of macronutrient, micronutrient and heavy metal pollution that may contaminate roadside plants. Adjacent landscape features such as railroads and agriculture provide additional macronutrient and heavy metal pollution that may exacerbate traffic effects. However, we lack perspective on how roads combine with rural landscape features to influence nutrition of roadside plants, which could have implications for pollinator health.
We surveyed roadsides across Minnesota, USA and measured foliar levels of dietary macronutrients (nitrogen, phosphorous and potassium), a micronutrient (sodium) and metals (iron, zinc, copper, chromium, nickel, lead, aluminium and cadmium) in six abundant roadside forb species used by insect pollinators: Asclepias syriaca, Dalea purpurea, Monarda fistulosa, Ratibida pinnata, Solidago spp. and Trifolium pratense. We aimed to determine (1) how road variables (traffic volume and distance from road) combine with adjacent land use (railroad and agriculture) to influence element content of roadside forbs and (2) whether some forb species show consistent differences in their accumulation of potentially toxic heavy metals, which could inform selection of species to plant along roadsides.
We found that foliar concentrations of nine elements increased with greater traffic volume (nitrogen, phosphorous, iron, zinc, copper, chromium, nickel, lead and aluminium), and concentrations of six elements declined with distance from the road (nitrogen, phosphorous, potassium, iron, zinc and copper). Leaves collected adjacent to railroad had less phosphorous, potassium, iron, nickel and aluminium than leaves collected from sites not adjacent to railroad. Additionally, leaves collected from sites adjacent to agriculture had lower copper levels than leaves from sites without adjacent agriculture. We found no evidence that particular ford species along roadsides consistently rank higher than other species in their accumulation of heavy metals.
Our results show that traffic alters more elements in roadside plants than does adjacent landscape context, alleviating concerns that landscape features exacerbate pollutant levels in roadside pollinator habitat. However, nutrient contamination of most roadside plants is unlikely to reach toxic levels for insect pollinators. This work is consistent with the positive conservation potential of low to moderate traffic roadsides for pollinators.

Published: December 2022

AbstractEnergy shortage and environmental degradation are two important challenges facing humanity. Here, a multi‐layer stacked triboelectric nanogenerator (MLS‐TENG) based on a rotation‐to‐translation mechanism is reported for fluid energy harvesting and environmental protection. The mechanism transforms fluid‐induced rotation into a reciprocal translation of the MLS‐TENG, enabling the conversion of fluid energy into electrical energy. In addition, benefiting from a multi‐layer stacked structural design, the open‐circuit voltage is increased from 860 to 2410 V and an efficient energy harvesting rate of 2 mJ min−1 is obtained in an actual river. Furthermore, with the assistance of the MLS‐TENG, a self‐powered wireless temperature and humidity monitoring system and a metal anticorrosion system are successfully established. Ambient monitoring data can be transmitted continuously at an interval of 49.7 s, and the corrosion rate of steel is significantly slowed down. This study provides guidance for efficient harvesting of ambient fluid energy, with promising applications in environmental monitoring and protection.

AbstractLow‐bandgap tin (Sn)‐lead (Pb) halide perovskites can achieve near‐infrared response for photodetectors. However, the Sn‐based devices suffer from notorious instability and high defect densities due to the oxidation propensity of Sn2+. Herein, a multifunctional additive 4‐amino‐2,3,5,6‐tetrafluorobenzoic acid (ATFBA) is presented, which can passivate surface defects and inhibit the oxidation of Sn2+ through hydrogen bonds and chelation coordination from the terminal amino and carboxyl groups. The perfluorinated benzene ring structure of ATFBA affords the passivator assembled at the grain boundaries to enhance the water resistance. With the synergistical passivation of these functional groups, the Sn–Pb perovskite photodetector exhibits a remarkable responsivity of 0.52 A W‐1 and an excellent specific detectivity of 5.34 × 1012 Jones at 850 nm, along with remaining 97% of its initial responsivity over 450 days. Benefitting from high sensitivity, the photodetector is integrated into a pulse oximetry sensor visualization system, yielding accurate blood oxygen saturation and heart rate with less than 2% error. This work paves the avenue toward constructing high‐performance and stable Sn–Pb perovskite photodetectors for practical applications.

Published: December 2022

AbstractPd/Cu‐catalyzed cross‐coupling of propargylamines with aromatic acyl chlorides (PdCl2, CuI, Ph3P, 40–45 °C) provides α‐aryl(hetaryl)aminoacetylenic ketones in a yield of up to 97%. The latter undergo cyclization to 1,2,5‐triaryl(hetaryl)‐1,2‐dihydro‐3H‐pyrrol‐3‐ones in up to 93% yield after the treatment with KOH or Et2NH (40–55 °C, aqueous ethanol). The one‐pot synthesis of the pyrrol‐3‐ones (in up to 62% yields) by consecutive treatment of the above propargylamines with acyl chlorides (PdCl2/CuI/Ph3P) and a base (KOH) in aqueous ethanol has been also developed.magnified image

Published: December 2022

AbstractThe use of subcutaneous devices has greatly advanced the field of medicine and surgery. However, localizing these devices internally requires imaging techniques such as X‐ray or ultrasound. A novel magnetic tracking system for subcutaneous medical devices is presented, providing the capability for precise device localization in an extremely compact and portable pocket‐size format. It is entirely benign, avoids X‐rays, and can be used to immediately confirm the proper instrument placement. It is implemented on umbilical catheters and endotracheal tubes and is characterized by bench‐test, cadaveric, and in vivo studies. The systems consist of a magnetic tip fixed to the distal end of the subcutaneous device, as well as a Magnetic Sensing‐Array Device that utilizes a matrix of magnetic field sensors to localize the magnetic tip. The bench‐tests show a high localization accuracy for a distance up to 4 cm. The accuracy is slightly reduced during cadaveric and in vivo tests, due to factors impacting the application, such as the dermal surface topography. Regardless, the magnetic subcutaneous medical device tracking system is shown to be robust in performance and functionality in real‐world clinical applications, and with its intuitive approach and portability, it has the potential to make real‐time subcutaneous device tracking widely accessible.

Published: December 2022

AbstractChallenging magnetic hyperthermia (MH) applications of immobilized magnetic nanoparticles require detailed knowledge of the effective anisotropy constant (Keff) to maximize heat release. Designing optimal MH experiments entails the precise determination of magnetic properties, which are, however, affected by the unavoidable concurrence of magnetic interactions in common experimental conditions. In this work, a mean‐field energy barrier model (ΔE), accounting for anisotropy (EA) and magnetic dipolar (ED) energy, is proposed and used in combination with AC measurements to a specifically developed model system of spherical magnetic nanoparticles with well‐controlled silica shells, acting as a spacer between the magnetic cores. This approach makes it possible to experimentally demonstrate the mean field dipolar interaction energy prediction with the interparticle distance, dij, ED≈ 1/dij3 and obtain the EA as the asymptotic limit for very large dij. In doing so, Keff uncoupled from interaction contributions is obtained for the model system (iron oxide cores with average sizes of 8.1, 10.2, and 15.3 nm) revealing to be 48, 23, and 11 kJ m−3, respectively, close to bulk magnetite/maghemite values and independent from the specific spacing shell thicknesses selected for the study.

AbstractThe combination of supported metal nanoparticles and functional host oxides catalyze many major industrial reactions. However, uniform dispersion and ideal chemical configuration of such nanoparticles, which determines the catalytic activity, are often difficult to achieve. In this study, a unique combination is proposed of heterogeneous doping and ex‐solution for the fabrication of Pt–Ni alloy nanoparticles on CeO2. By manipulating the reducing conditions, both the particle size and composition are precisely controlled, thereby achieving a highly dispersed and stable alloy nanocatalyst. The unique behavior of controlled alloy composition is elucidated through classical diffusion and precipitation kinetics with elemental analysis of the grain boundaries. Finally, Pt–Ni alloy nanocatalysts are successfully tuned showcasing a breakthrough performance compared to single element catalyst in reverse water gas shift reaction with superior stability and reproducibility.
