Turbulent Origins of Particle Intensity Dropout in Gradual Solar Energetic Particle Events During Solar Cycle 23
Authors: Tan Lun C.
Published: August 2023

Dropout is a low-energy particle phenomenon in which the particle intensity drops sharply and then rises rapidly during an impulsive or gradual solar energetic particle (SEP) event. We investigated dropouts in gradual SEP events during solar cycle 23, in which we identified 77 dropout periods with an average duration of approximately 1 hr. During most of the dropout periods, we observe large angles between the mean magnetic field and the solar wind velocity, implying that the slab turbulent component dominates. We therefore explore the origin of particle intensity dropout in slab turbulent environments. At a wave frequency of 1 Hz in the spacecraft frame, we observed a significant positive correlation between the turbulent power spectral density (PSD) and its spectral index, both in the ion dissipation range. As the input PSD decreases, the correlation can amplify the reduction factor for pitch-angle scatterings, quickly suppressing particle scattering through the 90° pitch angle. Hence, particle dropout may occur due to lack of spatial diffusion of particles.
Wave Generation and Energetic Electron Scattering in Solar Flares
Authors: Ma Hanqing , Drake J. F. , Swisdak M.
Published: August 2023

We conduct two-dimensional particle-in-cell simulations to investigate the scattering of electron heat flux by self-generated oblique electromagnetic waves. The heat flux is modeled as a bi-kappa distribution with a T
∥ > T
⊥ temperature anisotropy maintained by continuous injection at the boundaries. The anisotropic distribution excites oblique whistler waves and filamentary-like Weibel instabilities. Electron velocity distributions taken after the system has reached a steady state show that these instabilities inhibit the heat flux and drive the total distributions toward isotropy. Electron trajectories in velocity space show a circular-like diffusion along constant energy surfaces in the wave frame. The key parameter controlling the scattering rate is the average speed, or drift speed v

d
, of the heat flux compared with the electron Alfvén speed v
Ae, with higher drift speeds producing stronger fluctuations and a more significant reduction of the heat flux. Reducing the density of the electrons carrying the heat flux by 50% does not significantly affect the scattering rate. A scaling law for the electron scattering rate versus v

d
/v
Ae is deduced from the simulations. The implications of these results for understanding energetic electron transport during energy release in solar flares are discussed.

can be explained at least in part by contamination of the latter by terrestrial water. The discovery that a randomly sampled C-complex asteroid is composed of CI-chondrite-like rock, combined with thermal models for formation prior to significant decay of the short-lived radioisotope 26Al, suggests that if lithified at the time of alteration, the parent body was small (≪50 km radius). If the parent planetesimal was large (>50 km in radius), it was likely composed of high-permeability, poorly lithified sediment rather than consolidated rock.

Published: August 2023

Two new species and a first geographical record of Hohenbuehelia are described from Thailand. Macroscopic and microscopic descriptions with photoplates, as well as a multigene phylogeny are provided. Hohenbuehelia flabelliformissp. nov. is recognised by large flabelliform basidiomata, densely villose yellowish-white pileus with white hairs near the point of attachment, basidiospores that mostly are ellipsoid in front view and phaseoliform in side view, the absence of cheilocystidia, and a trichoderm pileipellis. Hohenbuehelia lageniformissp. nov. is characterised by fleshy basidiomata, velutinous pileus with whitish hairs near the point of attachment and the margin, elsewhere pale greyish-yellow and with only sparse white hairs, pale brown to light brown and mucilaginous context, subglobose basidiospores, lageniform cheilocystidia, an ixotrichoderm pileipellis, and the absence of pileoleptocystidia. Hohenbuehelia tristis is characterised by small creamy-white, spathuliform basidiomata that are larger than the type subspecies, minutely pubescent pileus with tiny greyish hairs that disappear when mature, leaving the surface glutinous, faintly translucent and shiny, ellipsoid to sub-ellipsoid basidiospores, lecythiform to sublageniform cheilocystidia, and an ixotrichoderm pileipellis. Hohenbuehelia tristis is recorded for Thailand for the first time. Based on the polymorphism observed in part of the nrLSU gene, the presence of two divergent lineages within H. tristis is discussed.
Testing a modified version of the EPPO decision-support scheme for release of classical biological control agents of plant pests using Ganaspis cf. brasiliensis and Cleruchoides noackae as case studies
Authors: Seehausen M. Lukas , Branco Manuela , Afonso Catarina , Kenis Marc
Published: August 2023

The 6/04 standard of the European and Mediterranean Plant Protection Organisation (EPPO) on the safe use of biological control is a decision-support scheme (DSS) for the import and release of biological control agents in Europe. It was recently developed by the Joint EPPO/International Organisation of Biological Control (IOBC) Panel on Biological Control Agents. The DSS can be used to assess the potential environmental impacts of biological control agents. It is valid for different types of biological control: classical and augmentative biological control of invertebrates, pathogens and weeds. However, the DSS is not yet widely implemented in Europe and, during preliminary trials, it was found that its broad range of usages could lead to some confusion or misunderstandings, as well as requiring unnecessary information in some cases. Thus, the scheme was modified to specifically assess classical biological control against plant pests, i.e. the introduction of exotic natural enemies of plant pests for establishment and long-term control. The new version of the scheme was then tested on two parasitoids that are presently being released in Europe, the figitid Ganaspis cf. brasiliensis against the spotted wing drosophila Drosophila suzukii and the mymarid Cleruchoides noackae against the Eucalyptus bronze bug Thaumastocoris peregrinus. Both parasitoids were successfully assessed with the new version of the DSS. No major issues were encountered during the assessments and most questions were answered with low levels of uncertainty. Both assessments concluded that the parasitoids were safe to release in the impact assessment areas, with positive impacts exceeding negative impacts. Suggestions for potential improvements are provided.

Published: August 2023

This paper discussed the study of the factors that determine the behavioural intention (BI) of teachers utilisation of cloud-based learning management systems (LMS) in Malaysian secondary schools. A survey methodology was introduced in this inquiry using 322 participants from 18 secondary schools in the country. Also, this research employed a structured questionnaire consisting of 43 questions that addressed seven factors: performance expectancy (PE), effort expectancy (EE), social influence (SI), facilitating conditions (FC), self-efficacy (SE), hedonic motivation (HM) and BI. The adoption of quantitative methodology was meant to allow the research to gather extensive numerical data to understand the problematic adoption of Google Classroom applications in Malaysian high schools. However, the data collected were analysed descriptively and inferentially. These research findings showed that there were relationships that existed between the independent variables and teachers’ BI towards the utilisation of cloud-based LMS in Malaysian secondary school settings. The results of this study are relevant from both academic and managerial perspectives, providing solutions for future research in educational technology.
Patient Monitoring for Personalized Mobile Health (PMH) based on Medical Virtual Instruments
Authors: B. Christina Sweetline  , C. Vijayakumaran  , A. Samydurai
Published: August 2023

One of the newest technologies, mobile health, has the potential to support the provision of care for older adults and offer them individualised treatment. This study’s goal is to evaluate the benefits and challenges of personalised mobile health (PMH) for elderly residential care. Virtual worlds are quickly integrating into the landscape of instructional technologies. One of the most well-known of these settings is Second Life (SL). Despite the potential of SL for health professions education, there aren’t many official SL applications for this purpose, and the effectiveness of these applications hasn’t been evaluated to the fullest extent possible. Similarly, it appears that nothing is known about the use of virtual worlds for continuing medical education. In order to better grasp the fundamentals of the aid of MVIs for personal health monitoring (PHM), we were able to pinpoint the key disease regions, sensors, channels, calculations and communication protocols. The main obstacles limiting MVIs’ degree of integration into the international health care system were also identified. The analysis demonstrates that MVIs offer an excellent possibility for the creation of affordable, personalised health systems that meet the unique equipment requirements of a certain field of medicine.

Dengue is the most important arthropod-borne viral infection of humans. However, its viral pathogenesis is still unknown. The information collected from dengue fatal cases is crucial for understanding the complex interactions between virulence and host factors. This study aimed to establish possible associations between the clinical characteristics, histopathological changes, replication, and tissue location of viral serotypes in dengue fatal cases. Clinical and histopathological characterizations, antigen localization in tissue, and detection of the infecting serotype and replication using real-time polymerase chain reaction were all performed on the dengue fatal cases. The majority of the cases involved people under the age of 20. Bleeding (48.3%), abdominal pain (44.8%), myalgia (52.9%), and headache (48.3%) were the most common clinical manifestations in the cases. There was multiorgan pathology, with histopathological changes primarily in the liver, spleen, and lung. Similarly, the viral antigen was found primarily in these organs; however, there were no associations between tissue changes, viral location, infecting serotypes, and replication processes. Dengue infection should be considered a multiorgan disease, the outcome of which is possibly not associated with the infecting viral serotype.

Sorbinska kiselina i njezine soli, kalijev i kalcijev sorbat prehrambeni su aditivi, odnosno konzervansi s antimikrobnim djelovanjem koji inhibicijski djeluju na plijesni i kvasce, ali i na neke bakterije. Sorbinska kiselina, zbog navedenih svojstava, ima široku primjenu uprehrambenoj industriji, a naročito za konzerviranje mliječnih proizvoda, slastičarskih i pekarskih proizvoda, majoneza, namaza, suhog voća, vina te za površinsku obradu prerađenih mesnih proizvoda. Mehanizan antimikrobnog djelovanja sorbata još nije u potpunosti istražen. Preporučeni dnevni unos sorbinske kiseline iznosi 25 mg/kg tjelesne mase te se smatra najmanje tosičnim konzervansom, iako u kombinaciji s drugim aditivima može stvarati spojeve štetne za zdravlje. Kako bi se utvrdilo moguće prekoračenja najveće dopuštene količine (NDK) sorbinske kiseline u proizvodima životinjskog podrijetla, tijekom petogodišnjeg razdoblja (2018. - 2022.) s hrvatskog tržišta prikupljeno je i analizirano 725 uzoraka, od čega 445 uzoraka mliječnih proizvoda i 280 uzoraka mesnih proizvoda. Od ukupnog broja uzoraka, sorbinska kiselina detektirana je u 37 uzoraka. Količina sorbinske kiseline u mesnim proizvodima kretala se u rasponu 6-73 mg/kg te u mliječnim proizvodima 6-797 mg/kg. U niti jednom od analiziranih uzoraka nije određena količina ovog aditiva veća od NDK definirane zakonodavstvom. Međutim, u cilju zaštite zdravlja potrošača nužna je daljnja sustavna kontrola ovog prehrambenih aditiva.

Published: August 2023

The study presented some haematological parameters and production characteristics of novel crossbred Romanov × Hissar and purebred Romanov sheep. A number of biochemical and haematological tests were performed to assess the level of adaptation of F1 crossbred progeny to local rearing conditions and evaluate its potential economic benefits for industrial production. The newly created crossbreed demonstrated significant increase in carcass production characteristics, with pre-slaughter weight increased by 29.2%, slaughter weight - by 39.7%, cooled carcass weight - by 40.5% and total yield ‒ by 8.2% compared to Romanov purebreed. The meat quality was also increased: fat content remained at the same level (6.6-6.8%), carcasses of F1 crossbreed lambs had higher relative weight of muscle tissue (78.8% vs. 73.3%), increased content of the 1st grade meat (94.6% vs. 91.6%), and higher caloric value of the meat (by 8.7%) compared to the parent purebreeds. An increased erythrocyte (by 3.1%) and leukocyte (by 6.45%) count was noted in the F1 rams. Haemoglobin level in F1 lambs was increased by 4.2%. Protein metabolism parameters were improved: blood serum total protein level ‒ by 11.2%, albumin ‒ by 11.4%, globulin ‒ by 10.4%, suggesting intensified protein metabolism in F1 lambs; this was also evidenced by the increased activities of aspartate transaminase (by 3.9%) and alanine transaminase (by 16.6%) in F1 lambs over Romanov purebred animals. Blood serum of crossbred lambs had higher bactericidal (by 1.92%), lysozyme (by 3.53%), and phagocytic activity. The increased haematological and biochemical parameters and enhanced antibacterial properties of serum indicate the enhanced metabolic activity in F1 crossbreed sheep and underlay the improved meat production parameters. Obtained results demonstrate increased adaptation of the novel crossbred to industrial rearing conditions and local microclimate of steppe zone of Ukraine, which is undergoing gradual aridization.

The paper summarises the importance of body language as the basis of communication between humans and horses. Understanding horse body language is crucial for successful communication. Horses in communication use their entire body from head to tail and will respond to even the smallest signs made by their human companions. Accordingly, humans should be aware of their body language and pay close attention to body language communication when working with horses. In this sense, there is also a need to increase research on equine welfare during human-horse interactions, assessing not only the negative but also their positive affective states.

CP-ABE Unveiled: A Path to Fine-Tuned Cloud Data Security
Authors: Naregal Keerti , Kalman Vijay
Published: August 2023

Cloud computing has revolutionized data storage and processing, but it has also introduced significant challenges in ensuring data privacy and access control. In this research paper, we explore and understand the potential of Ciphertext Policy Attribute-Based Encryption (CP-ABE) as a cryptographic solution for enhancing cloud security through fine-grained access control. Our exploration begins with a comprehensive analysis of CP-ABE, including its architecture, components, and encryption/decryption processes. We delve into the security aspects of CP-ABE, evaluating its strengths, advantages, and vulnerabilities. We conduct a thorough performance evaluation, analyzing its computational overhead and comparingits efficiency with other encryption techniques commonly used in the cloud. Our findings indicate that CP-ABE offers fine-grained access control and data confidentiality, empowering data owners to enforce complex access policies. However, challenges related to attribute authority trust, key escrow, and policy complexity must be addressed to ensure its robustness in real-world deployments.Ciphertext Policy Attribute-Based Encryption (CP-ABE) introduces a hopeful method for dealing with the challenges related to controlling who can access information and keeping data private in cloud computing.Our research contributes valuable insights into CP-ABE's security, performance, and practical applications.
Retranslation as Re-vision and Self-Reflective Criticism: A Comparative Analysis of two translations of Agnisakshi from Malayalam to English by Vasanthi Sankaranarayanan
Authors: George Chythan Ann , Das Sriparna
Published: August 2023

Agnisakshi by Lalithambika Antharjanam (1976), a significant work in the landscape of women’s writing and social novel in Malayalam, was translated into English by Vasanthi Sankaranarayanan and published by Kerala Sahitya Akademi in 1980. In a rare instance of self-retranslation, with 35 years between them, Vasanti Sankaranarayanan rendered a fresh translation of the same novel in 2015. Retranslations, according to Lawrence Venuti, establish their differences from the previous versions and these are guided more by ideological premises than by literary or linguistic lack in the previous translations. In contrast to the uncritical, adulatory position assumed by the translator in the first translation of Agnisakshi, the second one points to a translator who acknowledges the politics of the text, critically approaches it and, in her own words, “adds new dimensions from a feminist perspective”. This paper, by closely examining the conscious interventions Sankaranarayanan makes as a feminist translator, attempts to conceptualize retranslation as an act of re-vision and self-reflective criticism, wherein the translator makes herself more visible through her translational interventions. The attempt here is to understand how the politics of the text is engaged with through retranslation by an ideologically empowered translator.
The Role of Translation in Disseminating Feminist Thought in Telugu Context
Authors: Rajkumar Eligedi
Published: August 2023

This paper studies the role of intermediary agencies in translating global feminist knowledge into the Telugu1 context. Identifying translators, organisations, publishing houses and magazines as such agencies, it offers an analysis of the function of this feminist thought. The study discusses the ideologies of agents in using translation as a political instrument to construct feminist discourse in the Telugu context. While demonstrating how translation was used as a transmitter for the circulation of feminist ideas, it gauges the influence of global feminist thinking on Telugu feminist translators, writers and activists. It also throws light on the opposition met in translating feminist ideas into Telugu, intellectual efforts and the resistance provided by the feminist translators, writers, activists and publishers as agents of social change to make feminist translation work relevant in the Telugu context.

Tutors and Their Feedback in Online Tutorials: The Case in a Distance Teaching University
Authors: Setiani Made Yudhi , Scott Charles , Susanti Susanti
Published: August 2023

The purpose of this study was to analyze the extent to which tutors provided feedback in online tutorials at Indonesia Open University (Universitas Terbuka or UT), as well as tutors' constraint in providing that feedback. This qualitative study used both content analysis of 20 online tutorial classes to see tutors’ feedback and in-depth interviews with the tutors. The results of the study showed that only some tutors in the online tutorial classes provided feedback on discussions and assignments and that some tutors did not provide any feedback. The analysis of the feedback derived from the types of feedback coined by Alvarez, Espasa, and Guasch (2011), namely, corrective feedback, epistemic feedback, suggestive feedback, and epistemic+suggestive feedback. In the online tutorial classes at UT, some feedback from the tutors corresponded with the types of feedback from Alvarez, Espasa and Guasch. The tutors who provided feedback did so despite constraints such as a lack of time to give feedback to each student. Provision of feedback offered benefits and satisfaction to students, leading them to become more successful in online tutorials.

ABSTRACT

The increase in the price of fuel oil (BBM) in the third quarter of 2022 will have a huge impact on the economy of the community. In addition to inflation, which was also followed by an increase in the price of basic commodities, this also reduced people's mobility in the use of oil-fueled vehicles. The government should use this as a momentum to promote the use of electric vehicles. On the other hand, the price of electric vehicles is still relatively high (expensive) when compared to oil-fueled vehicles. Although from a financial perspective, the use of electric vehicles can be more profitable if it is reviewed within a certain period. This can be shown by the lower cost per kilometer between electric vehicles compared to oil-fueled vehicles. From the point of view of cost comparison analysis over a certain period, the use of electric vehicles is more profitable than oil-fueled vehicles. It is hoped that the tendency of the community can be diverted to using electric vehicles. So that it can indirectly reduce the use of oil-fueled vehicles which is in line with efforts to reduce global warming.
