Abstract. We report F-region airglow imaging of fossil plasma depletions around midnight that revived afresh under persisting thermospheric gravity wave (GW) activity. An all-sky imager recorded these events in OI 630 nm imaging over Ranchi (23.3° N, 85.3° E; mlat. ∼19° N), India, on 16 April 2012. Northward-propagating and east–west-aligned GWs (λ∼210 km, v∼64 m s−1, and τ∼0.91 h) were seen around midnight. Persisting for ∼2 h, this GW activity revived two co-existing and eastward-drifting fossil depletions, DP1 and DP2. GW-driven revival was prominently seen in depletion DP1, wherein its apex height grew from ∼600 to >800 km, and the level of intensity depletion increased from ∼17 % to 50 %. The present study is novel in the sense that simultaneous observations of thermospheric GW activity and the associated evolution of depletion in OI 630 nm airglow imaging, as well as that around local midnight, have not been reported earlier. The current understanding is that GW phase fronts aligned parallel to the geomagnetic field lines and eastward-propagating are more effective in seeding Rayleigh–Taylor (RT) instability. Here, GW fronts were east–west-aligned (i.e., perpendicular to the geomagnetic field lines) and propagated northward, yet they revived fossil depletions.

Published: May 2024

Abstract. Raman lidars are an important tool for measuring important atmospheric parameters including water vapor content and temperature in the troposphere and stratosphere. These measurements enable climatology studies and trend analyses to be performed. To detect long-term trends it is critical to have as reliable and continuous as possible calibration of the system and monitoring of its associated uncertainties. Here we demonstrate a new methodology to derive calibration coefficients for a rotational temperature Raman lidar. We use solar background measurements taken by the rotational Raman channels of the Raman Lidar for Meteorological Observations (RALMO) located at the Federal Office of Meteorology and Climatology MeteoSwiss in Payerne, Switzerland, to calculate a relative calibration as a function of time, which is made an absolute calibration by requiring only a single external calibration, in our case with a single radiosonde flight. This approach was verified using an external time series of coincident radiosonde measurements. We employed the calibration technique on historical measurements that used a Licel data acquisition system and established a calibration time series spanning from 2011 to 2015 using both the radiosonde-based external and solar background-based internal methods. Our results show that using the background calibration technique reduces the mean bias of the calibration by an average of 0.2 K across the altitude range of 1 to 16 km compared to using the local radiosoundings. Furthermore, it demonstrates the background calibration’s ability to adjust and maintain continuous calibration values even amidst sudden system changes in the system, which sporadic external calibration could miss. This approach ensures that climatological averages and trends remain unaffected by the drift effects commonly associated with using daily operational radiosondes. It also allows a lidar not co-located with a routine external source to be continuously calibrated once an initial external calibration is done.

Abstract. The paper presents a model intercomparison study to improve the prediction and understanding of Mediterranean cyclone dynamics. It is based on a collective effort with five mesoscale models to look for a robust response among ten numerical frameworks used in the community involved in the networking activity of the EU COST Action "MedCyclones". The obtained multi-model, multi-physics ensemble is applied to the high-impact medicane Ianos of September 2020 with focus on the cyclogenesis phase, which was poorly forecast by numerical weather prediction systems. Models systematically perform better when initialised from operational IFS analysis data compared to the widely used ERA5 reanalysis. Reducing horizontal grid spacing from 10 km with parameterised convection to convection-permitting 2 km further improves the cyclone track and intensity. This highlights the critical role of deep convection during the early development stage. Higher resolution enhances convective activity, which improves the phasing of the cyclone with an upper-level jet and its subsequent intensification and evolution. This upscale impact of convection matches a conceptual model of upscale error growth in the midlatitudes, while it emphasises the crucial interplay between convective and baroclinic processes during medicane cyclogenesis. The ten numerical frameworks show robust agreement but also reveal model specifics that should be taken into consideration, such as the need for a parameterization of deep convection even at 2 km horizontal grid spacing in some models. While they require generalisation to other cases of Mediterranean cyclones, the results provide guidance for the next generation of global convection-permitting models in weather and climate.
Measurement Report: Urban Ammonia and Amines in Houston, Texas
Authors: Tiszenkel Lee , Flynn James , Lee Shan-Hu
Published: May 2024

Abstract. Ammonia and amines play critical roles in secondary aerosol formation, especially in urban environments. However, fast measurements of ammonia and amines in the atmosphere are very scarce. We measured ammonia and amines with a chemical ionization mass spectrometer (CIMS) at the urban center in Houston, Texas, the fourth most populated urban site in the United States, during October 2022. Ammonia concentrations were on average 4 parts per billion in volume (ppbv), while the concentration of an individual amine ranged from several parts per trillion in volume (pptv) to hundreds of pptv. These reduced nitrogen compounds were more abundant during the weekdays than on weekends and correlated with measured CO concentrations, implying they were mostly emitted from pollutant sources. Both ammonia and amines showed a distinct diurnal cycle, with higher concentrations in the warmer afternoon, indicating dominant gas-to-particle conversion processes taking place with the changing ambient temperatures. Studies have shown that dimethylamine is critical for urban new particle formation (NPF), but currently, there are no amine emission inventories in global climate models (as opposed to ammonia). Our observations show that amines in general positively correlated with ammonia, indicating that it is reasonable for global models to use scaled-down ammonia concentrations (e.g., 0.1 %) as a proxy of urban dimethylamine concentrations to simulate urban NPF processes.
Through a Different Lens: Unravelling Perspectives on Women's Roles in Farming and Drought Resilience
Authors: Kosovac Anna , Grupper Madeline
Published: May 2024

Abstract. A gender difference exists in the access to resources and inclusion in decision-making in issues of drought and women are overwhelmingly denied a ‘voice’ in such a landscape (Clarke 2014). This is particularly prevalent in irrigation and farming communities which carry on a legacy of patriarchal stewardship over farming and agricultural matters. This study considers the role of women in farming practice in the Mallee Region and how they view their position as decision-makers in drought and water management. This study presents three key findings from interviews of women within the region: women are increasingly adopting the label ‘farmer’ so that they can be ‘counted’ and given decision-making power regarding drought and water. Interviewees also stated a distinct difference in gender relations within horticultural dryland farming, compared to irrigation farming. Namely, many found that that gender dynamics were more progressive and equal within dryland. Some stated that this was due to many irrigation farmers being recent migrants and more likely to have traditional gender roles in their own family units, resulting in a perceived subordination of women. The dynamic between white settler farming women and those who had recently settled in the area (migrants) was wholly unexpected and highlights a potential ‘us-and-them’ distinction in farming. Despite the psychological distance of drought during the time of the interviews (many had recently experienced flooding), there was nevertheless a strong sense of the danger of drought, and the foreboding sense that it was coming. Interviewees stated that women were pivotal during times of drought as they were the ones to draw on community networks for help, to apply for grants, and also to supplement family income from off-farm work.

Cell phone fiction: Serial poetics and platform vernacular
Authors: Nielsen Jakob Isak , Højer Henrik
Published: May 2024

Norms and conventions for cell phone fiction have been in the making for a long time without being clearly codified and established as commercially or critically viable mainstay phenomena. This paper explores new manifestations of the emerging poetics of cell phone fiction, meaning the narrative and stylistic principles by which audiovisual short form serial narratives are constructed with the cell phone as intended user interface. We analyze and discuss cell phone fiction developed by two commercial players, Quibi and SnapChat. We have chosen as our main cases two serials that are generically alike but nevertheless demonstrate significant differences of style and narrative design — When The Streetlights Go On (Quibi, 2020) and Class of Lies (Snap Originals, 2018). The main differences can be understood in relation to diverging forms of “platform vernacular” (Gibbs, et al., 2015). Despite its so-called turnstyle functionality, Quibi’s When The Streetlights Go On is shown to embrace the stylistic and narrative design of long form media, whereas SnapOriginals’ Class of Lies opts for a ‘vertical only’ platform, a hyper emphatic style as well as going a long way to accommodate its users and the vernacular of cell phone practices and practices associated with Snapchat as a social media application.

Authors: Belykh N. A. , Pisnyur I. V. , Nikiforov A. A. , Nikiforova L. V.
Published: May 2024

Introduction. Asthma is a widespread disease in childhood and has a persistent tendency to increase. Therefore, the search for factors influencing this process, as well as biomarkers reflecting the degree of asthma control, is an urgent problem.

   Objective. To study the relationship of vitamin D levels with the serum periostin and TGF-β1 concentration in children with asthma.

   Materials and methods. The cross-sectional (one-stage) study included 80 children aged 6 to 17 years (average age — 12 ± 3.2 g). The subjects were divided into 2 groups: children with asthma — group 1 (n = 40); group 2 — the control group (n = 40). In all children, the assessment of the concentration of 25(OH)D, periostin and TGF-β1 in the blood serum was studied.

   Results. Median (Me) 25(OH) in patients with asthma was statistically significantly lower than in children of the comparison group (16.7 ng/ml, versus 25.7 ng/ml, p = 0.017), and did not depend on the severity of the disease, corresponded to a deficiency condition in both mild (16.2 ng/ml) and with an average severity of asthma (16.8 ng/ml) (p = 0.041). Me of periostin in 1st group was within the normal range (730.2 ng/ml), but statistically significantly exceeded the indicator of 2nd group (539.7 ng/ml, p < 0.05) and did not depend on the age and duration of asthma. High rates of periostin were observed in children with moderate severity of asthma with a disease experience of 4–6 years (617.2 ng/ml). Me of TGF-β1 in both groups corresponded to normal values (309.0 and 369.6 pg/ml, respectively, p > 0.05) and did not depend on the age and duration of asthma.

   Conclusions. VD deficiency is registered in children with asthma 2 times more often than in healthy children in Ryazan region. The serum concentration of periostin increased in proportion to the severity of asthma. Vitamin D deficiency can be one of the risk factors for the development of asthma and lead to an imbalance in the periostin and TGF-β system.
The Policy of Belgrade towards the Turkish and the Albanian Minorities in the Yugoslav Federation with an Emphasis on Demography from the End of World War II to Tito's Death
Authors: Stamova Mariyana
Published: May 2024

In the article, the subject of research and analysis is the situation and status of the Turkish and Albanian minorities in the Yugoslav Federation after the Second World War, with an emphasis on Kosovo and Macedonia and the Yugoslav policy towards them. Because of the conflict with Kominform in June 1948 and the deterioration of the Yugoslav-Albanian relationship, the Belgrade leadership was worried about the reaction of the Albanian population in Yugoslavia. At the same time, to limit the demographic and ethnic invasion of the Albanians in Kosovo and Macedonia, Yugoslav authorities started a political campaign for their exportation. After the signing of the Yugoslav-Turkish agreement in 1953, which confirmed the convention from 1938 for the exportation of Turks from Yugoslavia in Turkey, the emigration into Turkey not only of Turks, but also Albanians, was legalized. Albanians in the Yugoslav federation got the possibility to define themselves as “Turks”, and thus to immigrate to Turkey (not Albania). In that way, many Albanians in Yugoslavia, mainly from Kosovo and Macedonia, declared themselves as “Turks”. In those years, Belgrade decided to intensify and renew the idea of emigrating the Muslim population, such as the Turks and Albanians, after World War II.

Exploring attributes of global CCS projects and the key factors to their accomplishment based on the CCUS project database
Authors: Qin Mingyu
Published: May 2024

In recent decades, the serious excessive level of carbon emissions has become the worthiest of human consideration to alleviate the problem. The negative impacts of carbon emissions on human beings involve a variety of aspects, such as sea level rise, deforestation, air pollution, global warming, etc. Any one of these issues could cause serious negative impacts on human society. In a large number of relevant studies, Carbon Capture and Storage (CCS) programs are considered to be the most promising and effective approach. The carbon produced during production is captured and transported to rock formations deep underground where it is centrally stored. There are nearly 300 CCS plants in operation around the world that demonstrate the feasibility of such projects. However, one relevant question is whether the project is costly and has barriers to deploy at a scale. We gathered a comprehensive list of large-scale CCS projects globally by utilizing the CCUS Projects Database. We then conducted a comparative analysis of these projects across various categories of project status, ensuring comparability by standardizing cost and extraction figures for each project. We found that the cost of Capture and Storage Projects is the highest, followed by just Capture Projects and just Storage Projects. These plants predominantly exist in developed regions: the U.S. hosts the most, then Europe, parts of Australia, with fewer plants scattered globally. Based on detailed project-specific information, we found that that the two most common reasons for suspended or closed plants are high costs without sufficient financial support and the impact of government agencies permissions and regulation. As such, improvement in the capital market and more policy support would be crucial for the deployment and operation of Carbon Capture and Storage projects.

Having been rapidly developing in recent years, the Asia-Pacific region is also equipped with a continuously expanding demand for the research and application of FRP materials. This paper summarizes the application of FRP materials in the Asia-Pacific region through literature and case analysis. Some of the current issues existing in the procedure of FPR materials application are discussed, and predictions on the development and application prospects of this kind of materials in the Asia-Pacific region are also briefly suggested. It is found that FRP materials have been widely utilized in various fields including concrete structures reinforcement, bridge engineering construction and new energy facilities in the Asia-Pacific region, where is equipped with a relatively broad and promising market. Meanwhile, the shortcomings relevant to this kind of materials in several aspects, such as expensive unit prices and imperfect technical specification systems, also restricted the application of FRP materials in this region.
Spatiotemporal evolutions and reasons of land-use carbon emissions in counties, Shaanxi Province, China
Authors: Zhou Wei , Chen Yao , Wang Qi , Wang Weifeng
Published: May 2024

Global warming caused by factors such as the expansion of construction land poses a major threat to the sustainable development of China. As an important component of China's low-carbon development strategy, there is a relative lack of analysis of the spatial and temporal evolution of land-use carbon emissions and the influencing factors at county-level. In this study, we employed Emission-Factor Approach to estimate carbon emissions from land use in 107 counties, Shaanxi province, China. Our findings revealed construction land were the primary contributors to carbon emissions, showing a substantial increase from 2000 to 2020. There was positive spatial autocorrelation in carbon emissions among counties, forming distinct aggregation patterns around the City of Xi'an and both the southern and northern regions of Shaanxi. By utilizing the Spatial Durbin Error Model (SDEM), demographic factors emerged as key drivers of carbon emissions, indicating the significance of addressing population concentration to curb emissions. Furthermore, promoting coordinated development and adjusting the economic structure in different counties can mitigate both population concentration and carbon emissions. Emphasizing industrial development and investments can also effectively suppress carbon emissions. Additionally, managing transportation-related emissions can be achieved by enhancing public transportation services and regulating private car usage.
An analysis of seashell calcium carbonate dissolution caused by ocean acidification based on chemistry equilibrium
Authors: Hu Keming
Published: May 2024

Ocean acidification is a serious marine ecosystem problem caused by the abundant human emission of CO2. It is now a prevalent cognition that the dissolution of CO2 tends to raise the concentration of H+ in the ocean and therefore make it more acidic. Anthropogenic CO2 emission exacerbates the situation. This will then lead to another obvious problem---the dissolution of calcium carbonate shells of certain ocean organisms. This article will present a brief dissolution model, which can provide an analysis of the acidification effects from two perspectives---both the forming and the dissolution of seashells. The model shows an exponential relationship between the dissolved Ca2+ concentration and the pH of seawater. It also presents the anticipation regarding a dissolution turning point in (approximately) 2090 under the RCP8.5 scenario. This turning point indicates an abrupt acceleration of calcium carbonate shells dissolution. The result depicts the drastic but possible change in the seawater solution system and gives a warning signal of a probable deadline for us to control the CO2 emission. Hopefully, it will attract more scholars to pay attention to this topic and figure out methodologies to avoid the possible tragedy.

This work is anticipated to serve as a reference and provide important insights into the reliability of mechanical products.
Urban Green-Space: Environmental Justice & Green Gentrification
Authors: Chang Chuantao
Published: May 2024

In cities across the world, both in the global South and North, the distribution of urban green spaces exhibits stark inequalities. Affluent neighborhoods are often graced with abundant, well-maintained parks and green areas, offering residents a higher quality of life and environmental benefits. In contrast, communities with lower incomes and minority populations frequently face a scarcity of such spaces, and the green areas they do have tend to be of lower quality. This disparity not only reflects broader social and economic inequities but also has significant implications for public health, environmental justice, and social cohesion. Efforts to rectify this imbalance, while well-intentioned, can inadvertently lead to gentrification. Improving green spaces in underserved neighborhoods often makes these areas more attractive to higher-income groups, driving up property values and living costs. This process can displace long-term, lower-income residents, ironically exacerbating the very inequalities such initiatives aim to address. The resulting gentrification can also lead to increased homelessness among the most vulnerable populations. Thus, urban planners and policymakers face a complex, paradoxical challenge: how to equitably enhance urban greenery without contributing to gentrification and the further marginalization of low-income communities. This dilemma underscores the need for inclusive, carefully considered strategies in urban environmental planning that prioritize the needs and voices of all residents, especially those in historically marginalized communities.
A review of process of methanol carbonylation to produce acetic acid
Authors: Yan Qingyi
Published: May 2024

Acidic corrosion plays a significant part in the compound business, particularly in the production of new substance fiber. As of now, the primary technique for creating acidic corrosive is the carbonylation of methanol utilizing iridium or rhodium organometallic edifices. The delegate techniques and the most recent advancement of methanol carbonylation to deliver acidic corrosion from two parts of homogeneous catalysis and heterogeneous catalysis are explored efficiently. The present homogeneous catalytic method and heterogeneous catalytic synthesis method using two different catalytic systems are introduced, followed in chronological order by the traditional method of producing acetic acid by carbonylation of methanol in the history of the chemical industry. The primary issues with producing acetic acid using conventional techniques are examined, including the product separation and the costly catalyst recovery. These issues can be resolved by developing and perfecting heterogeneous catalytic systems. The benefits and drawbacks of conventional techniques are broken down, the comprehensive summary and critical analysis of previous research provide comprehensive background knowledge, and the future exploration bearing is to work on the heterogeneous synergist framework to accomplish higher selectivity and preservation rate and work on financial proficiency.

Traumatic Hip Dislocation: Pediatric and Adult Evaluation and Management
Authors: Benedick Alexander , Lopas Luke , Daley Erika , Jang Yohan
Published: May 2024

Traumatic hip dislocation of a native hip joint represents an orthopaedic emergency that should be treated promptly. Dislocations can be classified based on the associated injuries and the direction of dislocation. Expeditious evaluation, reduction, and management of associated injuries are required to optimize short and long-term function of the hip. There are several important differences between the blood supply and ossification of the pediatric hip that necessitate different strategies for the evaluation and management of traumatic hip dislocations in pediatric patients. Appropriate treatment is dictated by the direction and type of dislocation as well as associated injuries. In addition to closed reduction, arthroscopy, open reduction (potentially with fracture fixation and/or soft-tissue repair), osteotomy, and total hip arthroplasty all have roles in treatment. Consensus on optimal postreduction activity protocols after simple hip dislocation remain unestablished. Short and long-term outcomes are largely driven by the amount of time from injury to reduction and associated injuries.

Published: May 2024

La práctica de técnicas de meditación, incluyendo entre ellas el yoga, está relacionada a mejores condiciones de salud general y a resultados más elevados en diferentes medidas psicológicas, además de más reducidos niveles de estrés entre los practicantes. El objetivo de la investigación fue evaluar el nivel de mindfulness, la satisfacción con la vida y la salud general de practicantes de alguna técnica de meditación, comparados a no practicantes. Participaron 224 personas adultas. Los participantes contestaron pruebas de mindfulness, satisfacción con la vida y salud general. Se encontraron diferencias entre los dos grupos para todas las medidas evaluadas, presentando mejores resultados los practicantes de meditación. No obstante, el tamaño del efecto fue distinto para las medidas de mindfulness, salud general y satisfacción con la vida. Se encontró correlación moderada entre el tiempo de la práctica de meditación y la medida de mindfulness. Los resultados señalan la fuerte relación entre la práctica de alguna técnica de meditación y el mindfulness. Se confirman los resultados de estudios previos que sugieren que la práctica de meditación puede contribuir a mejores condiciones de salud psicológica. Es interesante observar que en la muestra evaluada el tamaño del efecto para la medida de satisfacción con la vida es más bajo que los demás, lo que indica que, en esta situación, otros aspectos de la vida pueden estar más relacionados al resultado de satisfacción que no especialmente la práctica de meditación.

With the growing demand for Enterprise Resource Planning (ERP) literate graduates in the professional world, ERP education is an imperative aspect that has been integrated into universities. However, for many higher education institutions, the affordability of a commercial ERP system for courses is not practical. On the other hand, students struggle to grasp the concept of business processes and enterprise systems. They have difficulties in fully understanding the interrelationship of various ERP modules, especially new ERP features such as Business Intelligence (BI) and Business Analytics (BA), in meeting the holistic organisational objectives. This struggle was reinforced by the COVID -19 pandemic, which forced courses to be moved from face-to-face to online platforms. In this paper, a gamified mobile learning approach for ERP learning has been proposed and implemented to enhance ERP knowledge retention, improve the availability of ERP learning material, and expose new ERP features. The mobile application, named LearnES, consists of the application of gamification and adapted learning components based on various learning models. A research model with hypotheses was developed to test the outcomes of the solution, and the application was evaluated through a mixed survey-based approach. Following the evaluation, participants manifested a favourable attitude towards learning ERP through the mobile application.

The acceptance of Mobile commerce (M-commerce) applications has become a way of life for business professionals and mobile shoppers. The global acceptance and increase in its usefulness have resulted in concerns about the availability of a suitable model for its usability evaluation. In order to fill this literature gap, the study introduced the MObile Shoppers Application Development (MOSAD) usability model to address the limitations in current usability models when applied in the context of M-commerce applications. The proposed model in this study incorporates different essential attributes from widely accepted usability models, which helped develop a more detailed usability model for M-commerce applications. The attributes in the proposed model are not entirely new; however, the current and widely accepted usability models failed to consider some of them. This neglect could lead to usability evaluation flaws and affect the outcomes of usability evaluations of M-commerce applications.

This paper described the design of a compact printed monopole antenna with U-shaped Defected Ground Structure (DGS) for ultrawideband (UWB) application. The implementation of DGS facilitates in reduction of size and increases in antenna performance. The DGS and antenna design parameters are simulated using CST Microwave Studio 2020, and the measurement is carried out using R&S Vector Network Analyzer (VNA). The optimized design of the proposed UWB antenna with U-shaped DGS presented smaller in size (23.88mm x 29.10mm x 0.813mm) with a reduction of 32% compared to the conventional design, which fabricated on Rogers RO4003C substrate with a relative permittivity, εr = 3.38. Simulation results show that the proposed antenna provided a very wide range of frequency (3.2 - 20GHz), 144.8% of BW. The simulated and measurement results show good agreement.

Helminth parasites live in the human body and can cause serious health problems that will lead to cancer and may cause death in patients. These parasitic helminths congregate in the intestines to mate and produce ova. Therefore, early identification screening is necessary to prevent the spread of helminth parasites throughout the body. A manual microscopic feces test is still the most often used approach for helminth detection. As a result, the purpose of this research is to investigate the effectiveness of three classifiers in classifying four types of human intestinal parasite ova. Three classifier techniques used are k-Nearest Neighbourhood (k-NN), Support Vector Machine (SVM), and Ensemble classifier. There are four types of helminth ova which are Ascaris Lumbricoides Ova (ALO), Enterobius Vermicularis Ova (EVO), Hookworm Ova (HWO), and Trichuris Trichiura Ova (TTO). A total of 664 helminth parasite ova images were analyzed, consisting of 166 images from each helminth species. The Linear kernel function from the SVM classifier has obtained the highest accuracy performance reaching 92.23%. Followed by Cityblock distance from the k-NN classifier with an accuracy of 91.16% and AdaBoostM2 from the Ensemble classifier with an accuracy of 89.94%.
