Malaria ca tragedie națională: Semnele lui Dănuț (1922) de Gib I. Mihăescu
Authors: Dumitru Teodora
Published: September 2024

Some of Franco Moretti’s earliest works investigated the tragic form qua allegory of the desacralization of sovereignty and/ or as an allegory of civil war. Inspired by this type of conceptualization, in the present essay I turn the mirror on an endemic malady which I instrumentalize as an allegory of a national tragedy or as an allegory of the contemporary way of life (concerning especially the 19th-20th century way of life). In this vein, I assert that, just as a literary species can do that, a particular type of illness – an endemic one, such is malaria – can capture a symbolic function in literature. It is the function of expressing a collective drift, a bunch of socio-anthropological symptoms, specters of state policies or rather of their absence.
Tragicomedia Occidentului: emigrația economică în romanele și filmele românești din anii ’90
Authors: Borza Cosmin , Turcuș Claudiu
Published: September 2024

Our article examines the narrative registers and forms adopted in the 1990s by the Romanian novelists, screenwriters and film directors in order to portray the phenomenon of economic migration to the West. Our focus is on the intriguing and paradoxical employment of tragicomic, melodramatic, burlesque-grotesque and sensational narrative techniques as the Romanian collective imaginary during the 1990s witnessed the peak idealization of emigration in Western Europe and in The United States of America. This process of idealization is also fueled by the fact that, despite the political ban has been lifted after 1989, legislative and economic constraints continued to limit the actual experience of the so-called “free world.” The corpus of our article comprises two cult films of the period, Asfalt tango (1996, Nae Caranfil) and Cristian Mungiuʼs Occident (2002), as well as two novels authored Grid Modorcea and S. Dinger, all of which share the struggle to depict the tensions between the uncritical embrace of Western story-world and the bleak, if not dramatic, reality of migration.

Published: September 2024

Filozoflar yaşamla ilgili düşündüklerinde, bunu genellikle hayvanlar üzerinden yapmaya meyillidirler; bitkiler, çalışmalarında çoğunlukla arka plandadır, nadiren çalışmaların merkezinde oldukları görülür. Oysaki bitkiler, ekosistemlerin hayati derecede önemli parçalarıdır ve bitki yaşamı, bitki ve çevresi arasındaki etkileşimin çok ilginç halleri de dahil olmak üzere eşsiz süreçler içerir. Bitki biyolojisi, biyoloji felsefesi derslerinde önemli bir yere sahip olmalıdır. Ancak böylece öğrenciler, organizmaların ve organizma-çevre etkileşimlerinin kompleksite ve dinamikliğini, doğadaki çeşitliliği ve genel olarak, yaşamın süreçlerini daha zengin, kapsamlı ve iyi bir şekilde öğrenebilirler. Bunların yanında, bitkilere yeterli ilginin gösterilmesi, biyoloji felsefesinde bireylik, organizasyon ve hastalık gibi birçok konuda yeni ve ilginç yaklaşımlar sağlayacaktır. Bu tezi desteklemek için, bitki-çevre etkileşimi ile ilgili üç konu örnek olarak ana hatlarıyla anlatılacak ve bu konuların felsefi yansımaları açıklanacaktır. Birbirleriyle ilişkili olan bu üç konu: Büyüme, bitki hormonları ve bitki-bitki mikrobiyom etkileşimleridir. Bu konular; bireylik, sistem düşüncesi ve holobiyont tartışmaları gibi biyoloji felsefesindeki temel konulara önemli yaklaşımlar sunar.

Published: September 2024

The ever-growing energy demand, the intermittent nature of renewable energy resources such as wind, photovoltaic etc coupled with issues of reliability makes the hybrid renewable energy systems more preferred. Hybrid energy sources offers better reliability and cost effectiveness than a single energy source. One of the most important issues related to hybrid renewable energy systems is obtaining the optimal size of their parts so as to utilize them efficiently and economically. Determining the optimal size of hybrid energy systems helps to avoid over-sizing or under-sizing of the system which will subsequently affect the cost and reliability of the system. Optimal sizing becomes complex when considering multiple hybrid mix while at the same time considering various objectives such as cost, CO2 gas emission and reliability. This paper aims at critically reviewing the various optimization techniques used in optimal sizing of various combination of hybrid energy sources for effective selection of the appropriate sizing method for hybrid renewable energy systems. It has been found that meta-heuristic techniques are well suited for optimal sizing of the hybrid energy systems with Genetic Algorithm and Particle Swarm Optimization techniques being the most commonly used Algorithms.

Published: September 2024

Abstract. Trees established in linear formations can be utilised as windbreak structures on farms as a form of agroforestry system. We present an extensive data package collected from an active berry farm located near Stellenbosch, South Africa, considering hydrological, pedological, dendrological and meteorological measurements centred around an Italian alder (Alnus cordata (Loisel.) Duby) windbreak and a blackberry (Rubus fruticosus L. Var. “Waldo”) crop. Data were collected between September 2019 and June 2021. The data are available from Hassler et al. (2024) and include the following measurements (i) meteorological variables – solar radiation, precipitation characteristics, vapour pressure deficit, air temperature, humidity, atmospheric pressure, wind speed and direction, gust speed, and lightning strikes and distance recorded at 10 min intervals; (ii) hydrological measurements – soil moisture and matric potential in two profiles at 15 min intervals alongside soil samples at various depths describing soil texture, hydraulic conductivity, and water retention parameters; (iii) soil characteristics – a soil profile description accompanied by 60 topsoil samples describing carbon, nitrogen, and exchangeable base cation concentrations, as well as potential cation exchange capacity and descriptions of soil texture; and (iv) dendrological measurements – point cloud data for the studied windbreak trees and surrounding features, cylinder models of the windbreak trees with volume and biomass data, and foliage data as a product of an existing leaf creation algorithm. The described dataset provides a multidisciplinary approach to assess the impact and interaction of windbreaks and tree structures in agroforestry landscapes, aiding future work concerning water fluxes, nutrient distribution, microclimate and carbon sequestration. The dataset, including high-resolution time series and point cloud data, offers valuable insights for managing the windbreak's influence and serves as a unique training dataset for spatial analysis (https://doi.org/10.5880/fidgeo.2023.028, Hassler et al., 2024).
Terrace formation linked to outburst floods at the Diexi palaeo-landslide dam, upper Minjiang River, eastern Tibetan Plateau

Published: September 2024

Abstract. River terraces are frequently investigated with the aim of extracting information regarding tectonic or climate forcing on the evolution of landscapes. Terraces formed following the blockage of valleys by large-scale landsliding have received limited attention despite the high likelihood of their prevalence in landslide-dominated mountain belts. Here, we investigate the geomorphology, sedimentology, and chronology of two outstanding sets of terraces upstream of the giant river-blocking Diexi palaeo-landslide on the upper Minjiang River, eastern Tibetan Plateau. The first set occurs at Tuanjie village and has seven levels (T1–T7); the second set, at Taiping village, has three levels (T1–T3). All the terraces display a consistent sedimentary sequence comprising lacustrine muds topped by fluvial gravel sometimes capped by loess and a palaeosol. Based on field examination, lithofacies analysis, elevation data, and chronometric data (optically stimulated luminescence and radiocarbon dating), we correlate T1, T2, and T3 at Taiping with T5, T6, and T7 at Tuanjie. Our analysis suggests that two damming and three outburst events have occurred at the Diexi palaeo-landslide over the past 35 000 years. A giant landslide (> 300 m high) blocked the river before 35 ka, followed by the first outburst flood at ∼ 27 ka; the river was blocked again between 27 and 17 ka, followed by a second outburst at ∼ 17 ka. A third outburst at ∼ 12 ka was followed by gradual fluvial incision of the palaeo-dam crest to its current level. We attribute the terraces at Diexi to the recurrent blockage and outburst events, which reflect the shifting sediment transport capacity and incision at the palaeo-dam crest. Here, climatic fluctuations play a minor role in terrace formation, and tectonism plays no role at all.
Implementing the iCORAL (version 1.0) coral reef CaCO3 production module in the iLOVECLIM climate model
Authors: Bouttes Nathaelle , Kwiatkowski Lester , Berger Manon , Brovkin Victor , Munhoven Guy
Published: September 2024

Abstract. Coral reef development is intricately linked to both climate and the concentration of atmospheric CO2, specifically through temperature and carbonate chemistry in the upper ocean. In turn, the calcification of corals modifies the concentration of dissolved inorganic carbon (DIC) and total alkalinity in the ocean, impacting air–sea gas exchange, atmospheric CO2 concentration, and ultimately the climate. This feedback between atmospheric conditions and coral biogeochemistry can only be accounted for with a coupled coral–carbon–climate model. Here we present the implementation of a coral reef calcification module into an Earth system model. Simulated coral reef production of the calcium carbonate mineral aragonite depends on photosynthetically active radiation, nutrient concentrations, salinity, temperature, and the aragonite saturation state. An ensemble of 210 parameter perturbation simulations was performed to identify carbonate production parameter values that optimize the simulated distribution of coral reefs and associated carbonate production. The tuned model simulates the presence of coral reefs and regional-to-global carbonate production values in good agreement with data-based estimates, despite some limitations due to the imperfect simulation of climatic and biogeochemical fields driving the simulation of coral reef development. When used in association with methods accounting for bathymetry changes resulting from different sea levels, the model enables assessment of past and future coral–climate coupling on seasonal to millennial timescales, highlighting how climatic trends and variability may affect reef development and the resulting climate–carbon feedback.
OpenFOAM-avalanche 2312: depth-integrated models beyond dense-flow avalanches
Authors: Rauter Matthias , Kowalski Julia
Published: September 2024

Abstract. Numerical simulations have become an important tool for the estimation and mitigation of gravitational mass flows, such as avalanches, landslides, pyroclastic flows, and turbidity currents. Depth integration stands as a pivotal concept in rendering numerical models applicable to real-world scenarios, as it provides the required efficiency and a streamlined workflow for geographic information systems. In recent years, a large number of flow models were developed following the idea of depth integration, thereby enlarging the applicability and reliability of this family of process models substantially. It has been previously shown that the finite area method of OpenFOAM® can be utilized to express and solve the basic depth-integrated models representing incompressible dense flows. In this article, previous work (Rauter et al., 2018) is extended beyond the dense-flow regime to account for suspended particle flows, such as turbidity currents and powder snow avalanches. A novel coupling mechanism is introduced to enhance the simulation capabilities for mixed-snow avalanches. Further, we will give an updated description of the revised computational framework, its integration into OpenFOAM, and interfaces to geographic information systems. This work aims to provide practitioners and scientists with an open-source tool that facilitates transparency and reproducibility and that can be easily applied to real-world scenarios. The tool can be used as a baseline for further developments and in particular allows for modular integration of customized process models.
Continuum modeling of bioclogging of soil aquifer treatment systems segregating active and inactive biomass
Authors: Saavedra Cifuentes Edwin , Furman Alex , Rosenzweig Ravid , Packman Aaron I.
Published: September 2024

Abstract. Soil aquifer treatment (SAT) systems are used to remove pollutants from treated wastewater and store freshwater for reclamation and reuse. However, the accumulation of microbial biomass in the soil pore space, bioclogging, reduces water infiltration and hinders SAT efficiency. Since SAT systems play a crucial role in maintaining water resilience by providing an alternative to freshwater supply, optimizing their operation is essential to ensure their effectiveness. However, SAT systems are complex and dynamic systems that involve coupled interactions between microbial activity, water infiltration, and bioclogging in unsaturated media. This work proposes a continuum model that accounts for all these processes while distinguishing between active and inactive biomass, with the latter split into labile and recalcitrant fractions. The model is used to replicate a laboratory column experiment of bioclogging under unsaturated conditions and to explore how to optimize the operation of SAT systems. Specifically, we determined optimal wetting and drying periods that maximize water input to the SAT system while maintaining nutrient transformation rates. Our simulations show that the dry/wet time ratio controls biomass spatial distribution over depth. In contrast, the dry time extent dictates the degree of recovery of the soil relative to its initial (clean) infiltration capacity. We discuss the potential of this model to be extended to larger-scale experiments and to inform daily SAT operations in the field.

Spectroscopy is essential for research in the qualitative and quantitative analysis of samples. In recent years, the need to develop portable and accessible equipment for sample characterization has reduced real-time analysis. The objective is to design and build a prototype of a portable spectrophotometer with an integrating sphere using tools such as Rhinoceros and Trace-Pro for its theoretical design and radiation simulation. The result is an integrating sphere 3D printed with PLA material and an internal coating with a 95% high reflectance paint. The AS7265 Triad module is the detector, along with signal processing to obtain spectra from control samples. The spectral profiles obtained were comparable with commercial equipment, validating the viability of the measurement system as the first spectroscopic instrument in the field, in complement to other spectroscopic techniques. This breakthrough promises to facilitate research in the field and in environments where mobility and accessibility are priorities.

Published: September 2024

The elastic modulus of a grinding wheel is one of the most representative properties when it comes to the study of its in process behavior, which makes it a parameter of great interest for both researchers and manufacturers of grinding wheels. Rubber-bonded grinding wheels are characterized by their high elasticity, which makes them stand out in superfinishing applications, achieving surface roughness of Rz < 1 µm and mitigating the risk of burning the ground parts. Despite the good performance of this type of grinding wheel, they are not as popular as conventional rigid wheels, and their mechanical characteristics are still unknown. Moreover, while a few investigations have focused on determining the mechanical properties and their relationship with the in-process performance of vitrified or resinoid bonded grinding wheels, there are not investigations that have studied the mechanical properties of elastic grinding wheels. In this work, the elastic modulus, flexural strength and deformation of rubber-bonded elastic grinding wheels have been studied by means of three-point bending tests. Different compositions of the different materials that make up this type of grinding wheel have been analyzed, as well as the strength of the bond between the abrasive compound and the grinding wheel core. This study is intended to help to better understand the behavior of elastic grinding wheels and to develop more efficient grinding processes. In addition, it allows manufacturers to increase their knowledge of the properties of this type of grinding wheel and offers an effective method for its mechanical characterization.

Published: September 2024

This article describes the ideal conditions for heat-fixing a cotton-lycra-based fabric. Indeed, the heat setting process has an impact on the technical parameters of the fabrics, such as tensile strength, initiated tearing, elasticity and remanence. Knowing that fabrics containing lycras are delicate in terms of dimensional stability, the interest of this article is to contribute to the control of heat setting parameters with the aim of having optimal dimensional stability of fabrics. To do this, we considered 3 types of fabrics containing elastanes with different composition. From the tests and tests carried out, we obtained the ideal parameter values (including temperature and speed) for the heat fixing of fabrics.

Authors: Prakoso Gilang , Heikmakhtiar Aulia Khamas , Mantoro Teddy
Published: September 2024

Elliptic Curve Cryptography (ECC) is a contemporary form of asymmetric key cryptography widely employed in critical security domains, including encryption, decryption, and authentication. Its utilization has become increasingly prevalent in the Vital Information Infrastructure (IIV) to ensure secure communication and data exchange over time, driven by technological advancements and the growing size of data. This paper aims to provide a comparative relative efficiency analysis of ECC usage in the IIV, focusing on key aspects such as time efficiency, the relationship between curve size and security strength level, and the resilience of different curve sizes against Brute-Force attacks, Pollard Rho attacks, and Elliptic Curve Discrete Logarithm Problem (ECDLP) attacks. The results demonstrate that SECP521R1 features the largest key size and slowest key exchange time. Notably, SECP521R1 displays the highest level of resistance against various attacks, making it the most robust curve in terms of security.

Published: September 2024

Technology advancements have a big impact on how people learn. Knowing the condition of the millennials and Generation Z, their paradigms are considered as currently less enthused about the conventional lecture-based learning model and learning techniques as antiquated even dull particularly when studying foreign languages like Arabic. Therefore, it is quite necessary to study 1) the thinking paradigm of Arabic teachers; and 2) the role of the Arabic teacher’s thinking paradigm in achieving Arabic language learning objectives. This research took place at three State Islamic Senior High Schools in Tulungagung, East Java, Indonesia. Data sources in this research can be person, place, and paper. The data, participant observation, in-depth interviews, and documentation were used as data collection techniques and continued to check the validity of data-based credibility, transferability, dependability, and confirmability. Then, after the collected data were analyzed through the theory of Miles and Huberman. This result presented two points. First, the philosophical paradigm, language paradigm, learning paradigm, language learning paradigm, and Arabic language learning paradigm serve as the foundation for the thinking paradigms of Arabic teachers at State Islamic Senior High Schools in Tulungagung. Second, the paradigm of teaching readiness and learning readiness, followed by consistency with learning theory, is a key component of the Arabic teacher’s thinking paradigm that views the teacher as the learning center and the students as the learning center. This paradigm plays a significant role in the learning process.

Published: September 2024

The accessibility of electricity is fundamental to modern life. This study launches an automation system that provides an efficient way of storing and using electricity from a non-vanishing source – Solar Energy. The prototype consists mainly of an SPDT relay, a Photovoltaic Module, and USB ports. The researchers seek to reduce the adverse environmental effects of how electricity is conventionally generated from non-renewable resources by introducing a universal prototype that lessens the likelihood of fire-causing incidents, can harvest and store energy simultaneously, and may also be used as an alarm. In addition, this study seeks to present a solution to the exponential growth of electric power that is increasing exponentially from time to time. The results were based on three trials with different instruments and prototype components. The series of tests to determine the unregulated voltage of the photovoltaic module was measured using a multimeter that changes from time to time and varies from the intensity of the sun's radiation. Besides, the force that activates the pressure plate system requires at least 23.83N, and the safety of the prototype was measured using an infrared thermometer, which detects the temperature of an object wherein the pressure plate hot spots were measured.

Published: September 2024

The global rise in plastic demand and production, combined with the significant amount of plastics found in municipal solid waste, has led to the ubiquitous occurrence of microplastics (MPs) in the aquatic environment. This review examines the existing information on the origin, behaviour, fate, and effects of MPs on living organisms and the environment. In aquatic ecosystems, the reported high concentrations of MPs potential threat to the exposed organisms, causing blockage of the intestinal tract, alterations in feeding and digestive habits, injury, and death. Both fresh and aged MPs interact with different components of the aquatic ecosystem, leading to changes in their behaviour and bioavailability. Additionally, MPs often serve as vectors for sorbed pollutants and the chemicals leaching from their polymeric chains, enhancing the transportation of contaminants within the aquatic environment and to predators. With the current rate of plastic production and use coupled with the lack of proper waste management policies in many countries, the worries about environmental MPs have increased in recent years. Hence, a better understanding, continuous monitoring, and plastics management methods and waste control plans are crucial to address the issue of MPs in the environment.

Published: September 2024

The study was conducted to examine the knowledge of Lassa fever safety practices among garri processors and marketers in Edo State, Nigeria. A multi-stage sampling procedure was used to select 224 marketers and 192 processors, using a structured questionnaire and interview schedule. Data collected were described with the use of frequency counts, mean, and percentages while binary logistic regression was used to identify determinants of knowledge of safety practices and made some inferences.  Results showed that regular elimination of rats (54.0% and 54.7%) and maintenance of personal hygiene (53.1% and 89.6%) were the safety practices highly known by the marketers and processors of garri, respectively and the overall level of knowledge of Lassa fever safety practices among respondents was rated low with 63.6% and 54.5%, of marketers and processors, respectively. It was established that age (wald = 4.720), marketing experience (wald = 4.288), level of education (wald = 2.512), household size (wald = 3.052) and income from garri (wald = 3.237) were the significant determinants of the level of knowledge among garri marketers while marital status (wald = 4.464) and income (wald = 3.483) significantly determined the knowledge level of the processors. The findings conclude that both garri marketers and processors recorded a low level of knowledge of Lassa fever safety practices in the study area. It is, therefore, recommended that intense publicity and campaigns against Lassa fever should be carried out for processors and marketers of garri in the study area. This will sustainably reduce the spread of Lassa fever by the stakeholders in the Ministry of Health and other allied ministries and agencies to sustainably control the outbreak of this disease.
