Published: March 2024

Abstract. Prior aerosol chamber experiments show that the ligand-to-metal charge transfer absorption in iron(III) chlorides can lead to the production of chlorine (Cl2/Cl). Based on this mechanism, the photocatalytic oxidation of chloride (Cl−) in mineral dust–sea spray aerosols was recently shown to be the largest source of chlorine over the North Atlantic. However, there has not been a detailed analysis of the mechanism that includes the aqueous formation equilibria and the absorption spectra of the iron chlorides nor has there been an analysis of which iron chloride is the main chromophore. Here we present the results of experiments measuring the photolysis of FeCl3 ⋅ 6H2O in specific wavelength bands, an analysis of the absorption spectra of FeCln3-n (n=1 … 4) made using density functional theory, and the results of an aqueous-phase model that predicts the abundance of the iron chlorides with changes in pH and iron concentrations. Transition state analysis is used to determine the energy thresholds of the dissociations of the species. Based on a speciation model with conditions extending from dilute water droplets and acidic seawater droplets to brine and salty crust, as well as the absorption rates and dissociation thresholds, we find that FeCl2+ is the most important species for chlorine production for a wide range of conditions. The mechanism was found to be active in the range of 400 to 530 nm, with a maximum around 440 nm. We conclude that iron chlorides will form in atmospheric aerosols from the combination of iron(III) cations with chloride and that they will be activated by sunlight, generating chlorine (Cl2/Cl) from chloride (Cl−) in a process that is catalytic in both chlorine and iron.
Modelled forest ecosystem carbon–nitrogen dynamics with integrated mycorrhizal processes under elevated CO2

Published: March 2024

Abstract. Almost 95 % of all terrestrial plant species form symbioses with mycorrhizal fungi that mediate plant–soil interactions: mycorrhizae facilitate plant nitrogen (N) acquisition and are, therefore, vital for plant growth, but they also build a pathway for plant-assimilated carbon (C) into the rhizosphere. Therefore, mycorrhizae likely play an important role in shaping the response of ecosystems to environmental changes such as rising atmospheric carbon dioxide (CO2) concentrations, which can increase plant N demand and the transfer of plant C assimilation to the soil. While the importance of mycorrhizal fungi is widely recognised, they are rarely represented in current terrestrial biosphere models (TBMs) explicitly. Here, we present a novel, dynamic plant–mycorrhiza–soil model as part of the QUINCY (QUantifying Interactions between terrestrial Nutrient CYcles and the climate system) TBM. This new model is based on mycorrhizal functional types that either actively mine soil organic matter (SOM) for N or enhance soil microbial activity through increased transfer of labile C into the rhizosphere, thereby (passively) priming SOM decomposition. Using the Duke Free-Air CO2 Enrichment (FACE) experiment, we show that mycorrhizal fungi can have important effects on projected SOM turnover and plant nutrition under ambient as well as elevated-CO2 treatments. Specifically, we find that including enhanced active mining of SOM for N in the model allows one to more closely match the observations with respect to observed decadal responses of plant growth, plant N acquisition and soil C dynamics to elevated CO2, whereas a simple enhancement of SOM turnover by increased below-ground C transfer of mycorrhizae is unable to replicate the observed responses. We provide an extensive parameter uncertainty study to investigate the robustness of our findings with respect to model parameters that cannot readily be constrained by observations. Our study points to the importance of implementing mycorrhizal functionalities in TBMs as well as to further observational needs to better constrain mycorrhizal models and to close the existing major knowledge gaps in actual mycorrhizal functioning.
Synergistic use of Sentinel-2 and UAV-derived data for plant fractional cover distribution mapping of coastal meadows with digital elevation models

Published: March 2024

Abstract. Coastal wetlands provide a range of ecosystem services, yet they are currently under threat from global change impacts. Thus, their monitoring and assessment is vital for evaluating their status, extent and distribution. Remote sensing provides an excellent tool for evaluating coastal ecosystems, whether with small-scale studies using drones or national-/regional-/global-scale studies using satellite-derived data. This study used a fine-scale plant community classification of coastal meadows in Estonia derived from a multispectral camera on board unoccupied aerial vehicles (UAVs) to calculate the plant fractional cover (PFC) in Sentinel-2 MultiSpectral Instrument (MSI) sensor grids. A random forest (RF) algorithm was trained and tested with vegetation indices (VIs) calculated from the spectral bands extracted from the MSI sensor to predict the PFC. Additional RF models were trained and tested after adding a digital elevation model (DEM). After comparing the models, results show that using DEM with VIs can increase the prediction accuracy of PFC up to 2 times (R2 58 %–70 %). This suggests the use of ancillary data such as DEM to improve the prediction of empirical machine learning models, providing an appropriate approach to upscale local studies to wider areas for management and conservation purposes.
HETerogeneous vectorized or Parallel (HETPv1.0): an updated inorganic heterogeneous chemistry solver for the metastable-state NH4+–Na+–Ca2+–K+–Mg2+–SO42−–NO3−–Cl−–H2O system based on ISORROPIA II
Authors: Miller Stefan J. , Makar Paul A. , Lee Colin J.
Published: March 2024

Abstract. We describe a new Fortran computer program to solve the system of equations for the NH4+–Na+–Ca2+–K+–Mg2+–SO42-–NO3-–Cl−–H2O system, based on the algorithms of ISORROPIA II. Specifically, the code solves the system of equations describing the “forward” (gas + aerosol input) metastable state but with algorithm improvements and corrections. These algorithm changes allow the code to deliver more accurate solution results in formal evaluations of accuracy of the roots of the systems of equations, while reducing processing time in practical applications by about 50 %. The improved solution performance results from several implementation improvements relative to the original ISORROPIA algorithms. These improvements include (i) the use of the “interpolate, truncate and project” (ITP) root-finding approach rather than bisection, (ii) the allowance of search interval endpoints as valid roots at the onset of a search, (iii) the use of a more accurate method to solve polynomial subsystems of equations, (iv) the elimination of negative concentrations during iterative solutions, (v) corrections for mass conservation enforcement, and (vi) several code structure improvements. The new code may be run in either a “vectorization” mode wherein a global convergence criterion is used across multiple tests within the same chemical subspace or a “by case-by-case” mode wherein individual test cases are solved with the same convergence criteria. The latter approach was found to be more efficient on the compiler tested here, but users of the code are recommended to test both options on their own systems. The new code has been constructed to explicitly conserve the input mass for all species considered in the solver and is provided as open-source Fortran shareware.

Published: March 2024

Abstract. Leads and fractures in sea ice play a crucial role in the heat and gas exchange between the ocean and atmosphere, impacting atmospheric, ecological, and oceanic processes. We estimated lead fractions from high-resolution divergence obtained from satellite synthetic aperture radar (SAR) data and evaluated them against existing lead products. We derived two new lead fraction products from divergence with a spatial resolution of 700 m calculated from daily Sentinel-1 images. For the first lead product, we advected and accumulated the lead fractions of individual time instances. With those accumulated divergence-derived lead fractions, we comprehensively described the presence of up to 10 d old leads and analyzed their deformation history. For the second lead product, we used only divergence pixels that were identified as part of linear kinematic features (LKFs). Both new lead products accurately captured the formation of new leads with widths of up to a few hundred meters. We presented a Lagrangian time series of the divergence-based lead fractions along the drift of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in the central Arctic Ocean during winter 2019–2020. Lead activity was high in fall and spring, consistent with wind forcing and ice pack consolidation. At larger scales of 50–150 km around the MOSAiC expedition, lead activity on all scales was similar, but differences emerged at smaller scales (10 km). We compared our lead products with six others from satellite and airborne sources, including classified SAR, thermal infrared, microwave radiometer, and altimeter data. We found that the mean lead fractions varied by 1 order of magnitude across different lead products due to different physical lead and sea ice properties observed by the sensors and methodological factors such as spatial resolution. Thus, the choice of lead product should align with the specific application.
Short communication: Problems of classifying predator-induced prey immobility – an unexpected case of post-contact freezing
Authors: Ulate Gómez Teresita N. , Welch Antonia E. , Peters Winfried S.
Published: March 2024

Abstract. Prey noticing predators may turn immobile to avert detection. Such “freezing” is generally thought to precede direct predator–prey contact and thus appears distinct from so-called “post-contact immobility”, or thanatosis. This distinction, however, may be inapplicable if predators lack long-distance senses or monitor their surroundings incompletely. The predatory sandy beach gastropod Agaronia propatula (Olividae) detects its prey, Pachyoliva semistriata of the same family, only when located within centimetres in front of the predator. Pachyoliva therefore reduces its risks by active flight when directly approached by an Agaronia, whereas it freezes to remain undetected when contacting Agaronia from the side. This unexpected “post-contact freezing” suggests that physical contact between prey and predator as such does not always help to distinguish freezing from other types of predator-induced prey immobility and highlights how our interpretations of predator–prey interactions depend critically on our understanding of the sensory capabilities involved.

A Review on Application of Soft Computing Techniques for Load Shedding in Power Systems
Authors: Nagesh H. , Shivakumara Aradhya R. S.
Published: March 2024

In power systems, system frequency decreases if load exceeds generation and increases when power generation is greater than load demand. Load shedding is highly required in power systems to stabilize frequency in electrical power systems. Though conventional load shedding techniques are being used in many power system applications, soft computing techniques such as artificial neural networks (ANNs), fuzzy logic, genetic algorithm and particle swarm optimization have been presented by many researchers to provide optimum load shedding. However, there are many problems associated with machine learning based control techniques in real time. In this work, the utilization of soft computing algorithms and its benefits and drawbacks are discussed. A comprehensive survey is presented about the soft computing based load shedding and comparison is made among these techniques and conventional techniques. Neural network based learning rule is applied with back propagation network to minimize the error. In fuzzy based technique, load shedding position at each node was predetermined by applying certain fuzzy rules. Genetic algorithm and particle swarm optimization are robust and applied to solve many nonlinear and multi-objective problems. ANN and fuzzy logic are combined to build an adaptive neuro fuzzy inference system to provide accurate load shedding.

Multi-Objective, Short-Term Hydrothermal Scheduling Based on Weighting Method Using Particle Swarm Optimization
Authors: George Abraham , Shree Ram Bhagwan , Premalatha P.
Published: March 2024

This paper describes an algorithm to solve multi-objective, short term hydrothermal scheduling problem incorporating a few new techniques to make it more simple and fast. Multi-objective hydrothermal scheduling problem allocates the system generation among the available hydro and thermal generators such that an overall satisfactory solution to the problem of optimizing the objectives viz. cost of generation, emission of NOx, emission of CO2 and emission of SO2 is obtained. There are several methods to solve this problem but ‘Weighting method’ stands out of all. In weighting method, a composite objective function, combining all the given objectives, is formed assigning a suitable weight to each objective provided that the sum of the weights is equal to one. Normal practice is to assume a set of weight vectors, solve the problem considering each weight vector and go for the best overall satisfactory solution. In the method described in this paper,a set of weight vectors are randomly generated and the problem is solved for each weight vector. Further the weight vectors are modified and the problem is solved for each modified weight vector. This process is continued till the index of satisfaction is the highest. Modification of the weight vectors is done incorporating a new technique called ‘search space reduction technique’and introducing fuzzy acceleration factors. With modification of weight vectors using PSO highly efficient weight vectors/best possible solution to the hydrothermal scheduling problem can be obtained in minimum number of trials. The algorithm developed is tested on different systems and satisfactory solutions are obtained. The algorithm is simple and fast and gives a set of solutions with index of satisfaction falling in a narrow range for the multi-objective, short term hydrothermal scheduling problem.

Exploring Attentional Dynamics in Animated Programming Environments: Trajectories, Variability, and Predictors
Authors: Yusuf Abdullahi , Md Noor Norah , Adeyemi Yusuf Lateef
Published: March 2024

Researchers have proposed that the ability to pay attention to teachers’ instruction is a prerequisite for learning. However, meaningful learning is often challenged by the presence of rule-breaking behaviors. In this study, we argue that although students exhibit different attention-related behaviors in all instructional settings, some behaviors are unique to a typical classroom. It is still unclear what factors uniquely determine students’ attention-related behaviors in animated programming environments because of the paucity of research evidence in this area. This study investigates students’ attention-related behaviors during animated programming instruction, including attentional growth trajectory, the nature of differences in attention-related behaviors, and predictors of these behaviors. Our analysis involved 8 classroom videos that collected the programming activities of 30 university students in our previous study. The video files were annotated on a one-dimensional, continuous scale, yielding 1,920 timestamped data points. The data on attentional trajectories and differences in attention-related behaviors were analyzed using latent and multi-level growth modeling, respectively, while data focusing on the predictors of attentional processes were analyzed using the Random Forest machine learning algorithm. We found that students’ attentional growth trajectory is linear and accelerates toward on-task events. However, these behaviors vary within and between students, leading to differences in attention-related behaviors. The results also revealed that individual and instructional characteristics predict the differences in attention-related behaviors. The findings highlight the importance of structured topics, safe classroom environments, quality instructional support, and interactive multimedia objects that activate students’ memory, eliminate task difficulty, and reduce the amount of mental resources required for meaningful learning.

Published: March 2024

Increase users of sharia contracts is directly proportional to the increase in sharia economic disputes. The occurrence of disputes can be caused by one party breaking a contract or committing an unlawful act. In the event of a dispute, the party who feels aggrieved can submit a lawsuit to the court, but it turns out that during the examination of the case the judge found that the contract used was deemed not in sharia complience, while none of the parties filed a lawsuit for cancellation the contract. In this study, the authors used normative juridical research methods. by exploring the provisions of the supreme court which serve as guidelines for judges in examining cases of sharia economic disputes, while also using a conceptual approach by looking at Islamic law concepts regarding inappropriate contracts. with Islamic law. In this study the authors conclude that there are still many legal voids governing sharia economics, the existing provisions only regulate in general and universally, even contradicting each other.

Authors: Jiménez Jiménez José de Jesús , De Hoyos Martínez Jesús Enrique , Álvarez Vallejo Alberto
Published: March 2024

La actual crisis derivada de la pandemia del virus SARS-CoV-2 ha sido provocada, en gran medida, entre otros factores, por la facilidad que tiene la sociedad actual para moverse entre zonas y regiones en el territorio. Las pautas de contacto personal, así como la posibilidad de desplazarse a grandes distancias en relativamente poco tiempo han favorecido el crecimiento del fenómeno y las amenazas para la salud de la población. Muchas de las actividades humanas han sufrido cambios en su desempeño y muchos de éstos permanecerán en el futuro. La movilidad es una de estas actividades que ha sido severamente controlada en la intención de combatir la propagación del virus. Desde la aparición de éste en Wuhan, China, los gobiernos impusieron severas restricciones en los desplazamientos en todos los medios y servicios de transporte (Null y Smith, 2020). El control de la movilidad puede considerarse como una media que contribuye a la resiliencia del sistema y que coadyuva a la sostenibilidad urbana del mismo. Se requiere un mayor análisis de la relación movilidad-resiliencia-pandemia bajo un marco analítico objetivo. Por lo anterior, el presente capítulo propone un marco teórico-cognitivo que contribuya a un mejor entendimiento de las relaciones entre la movilidad de la población y la magnitud de la pandemia del virus SARS-CoV-2, para contribuir a la sostenibilidad y resiliencia de la ciudad desde el enfoque de los sistemas complejos y la dinámica urbana.

Commentary: Nepal's Balancing Act in the Middle East
Authors: Jaiswal Pramod , Aroman Bundit
Published: March 2024

Nepal was the first South Asian country to establish diplomatic relations with Israel in 1960, and other Middle Eastern countries followed suit in the late 1970s and early 1980s. Although Nepal and Israel have excellent bilateral relations, Nepal has yet to support Israel in multilateral forums, owing to a dilemma in maintaining balanced relations with other Middle Eastern countries. Because Middle Eastern countries are commonly identified by their reliance on labor imports, they have also become a labor destination for Nepal. With a high concentration of Nepali workers (77%), countries such as the UAE, Qatar, Cyprus, Bahrain, Israel, Saudi Arabia, and Kuwait have dominated Nepal's labor migration. Remittances from these countries are huge every year, and they have become the backbone of Nepal's economy. As a remittance-driven economy, labor export has always been a major tool of Nepal's economic diplomacy, which is frequently at the forefront of Nepal's foreign policy toward Middle Eastern nations. As a result, the paper argues for more determined action in the Middle East region, through which Nepal can develop its economic, investment, trade, and tourism interests by negotiating more advantageous relationships with Middle Eastern countries.
Design of a High Flux Beam Characterization Device for Falling Particle Receivers
Authors: Schroeder Nathan , Smith Braden
Published: March 2024

This paper outlines the design and error analysis for a flux characterization device (i.e. flux wand) which traverses the aperture of a falling particle receiver cavity providing the incident power measurement needed for the calculation of receiver efficiency without significantly disrupting receiver output. The design features a linear actuator, water cooled extension arm, and refractory bar. The refractory bar/flux wand is a diffusely reflective surface which reflects light as it is translated across the receiver aperture to provide a light intensity distribution that is correlated to a measured flux. The component sizing, constrained by a typical 30 frame per second camera and a 4-point average of the measured reflectance, is presented. Simulation reveals the error that results from a 5% variation in flux wand reflectance is within 4% of the true value.
