Authors: Lv Chenglong , Esamdin Ali , Hasanzadeh A. , Ma Shuguo , Yang TaoZhi , Karimov Rivkat
Published: December 2023

We report seven newly identified high-amplitude δ Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation of non-radial modes. TIC 30977864 is classified as a double-mode HADS star, while the other four stars potentially show triple-mode HADS behavior. TIC 112682462 and TIC 255603395 closely resemble RR Lyrae stars based on their light curves, position in the period–luminosity diagram, and the period ratio diagram. However, without spectral observations, it is challenging to ascertain whether these two stars are HADS or RR Lyrae stars. TIC 281695001 exhibits a fundamental frequency amplitude smaller than that of the first overtone, suggesting the presence of intriguing phenomena that necessitate further analysis.  We analyzed the relationship between metallicity and period using data provided by Netzel & Smolec. The metallicities of the 176 stars display a broad distribution ranging from −2.0 dex to 0.5 dex, with periods spanning 0.05 to 0.20 days. This random distribution of metallicities may contribute to the dispersion observed in the P1/P0 ratio. To derive more accurate conclusions, future spectroscopic observations of a larger sample of HADS stars are crucial. These observations will provide precise rotational velocities and more accurate determinations of metallicities.
Observations of Multiphase, High-velocity, Shocked Gas in the Vela Supernova Remnant*
Authors: Ritchey Adam M.
Published: December 2023

We present an analysis of high-resolution far-UV archival spectra obtained with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope of the star HD 75309, which probes high-velocity shocked gas in the Vela supernova remnant (SNR). We examine high-velocity features from intrinsically strong absorption lines of O i, Si ii, Si ii*, C ii, C ii*, and Si iii. We also detect high-velocity components in the N v doublet and compare these features to observations of high-velocity O vi absorption, available from archival Far Ultraviolet Spectroscopic Explorer data. Kinetic temperatures are derived from the observed fractional abundances of the various ions, while gas densities and thermal pressures are obtained from the relative populations in excited fine-structure levels of C ii and Si ii. Our results indicate that the highly ionized species at high velocity probe gas in a region immediately behind a shock driven into an interstellar cloud, while the lower-ionization species trace material further downstream in the cooling region of the postshock flow. Low-velocity N v and O vi absorption may trace gas in a conductive boundary layer between the unshocked portion of the cloud and the hot X-ray-emitting intercloud medium. Temporal variations in high-velocity Ca ii absorption features observed toward HD 75309 further confirm the highly inhomogeneous nature of the interstellar medium interacting with the Vela SNR.
Energization of Charged Test Particles in Magnetohydrodynamic Fields: Waves versus Turbulence Picture
Authors: Pugliese F. , Brodiano M. , Andrés N. , Dmitruk P.
Published: December 2023

Direct numerical simulations of three-dimensional compressible magnetohydrodynamic (MHD) turbulence have been performed in order to study the relation between wave modes and coherent structures and the consequent energization of test particles. Moreover, the question of which is the main mechanism of this particle energization is rigorously discussed. In particular, using the same initial conditions, we analyzed the nonlinear and linear evolution of a turbulent state along with the case of randomized phases. Then, the behaviors of the linear and nonlinear simulations were compared through the study of the time evolution of particle kinetic energy and preferential concentration. Also, spatiotemporal spectra were used to identify the presence of wave modes and quantify the fraction of energy around the MHD modes in linear and nonlinear simulations. Finally, the variation of the correlation time of the external forcing is studied in detail along with the effect on the particle energization (and clustering) and the presence of wave modes. More specifically, particle energization tends to decrease when the fraction of linear energy increases, supporting the idea that energization by structures is the dominant mechanism for particle energization instead of resonance with wave modes as suggested by Fermi energization theory.

Accreting supermassive black holes (SMBHs) located at the centers of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circumnuclear material can be studied at different wavelengths, from the submillimeter to the X-ray. Recent X-ray studies have shown that the covering factor of the obscuring material tends to decrease with increasing Eddington ratio, likely due to radiative feedback on dusty gas. Here we study a sample of 549 nearby (z ≲ 0.1) hard X-ray (14–195 keV) selected nonblazar active galactic nuclei (AGN) and use the ratio between the AGN infrared and bolometric luminosity as a proxy of the covering factor. We find that, in agreement with what has been found by X-ray studies of the same sample, the covering factor decreases with increasing Eddington ratio. We also confirm previous findings that showed that obscured AGN typically have larger covering factors than unobscured sources. Finally, we find that the median covering factors of AGN located in different regions of the column density–Eddington ratio diagram are in good agreement with what would be expected from a radiation-regulated growth of SMBHs.
Investigation of Emission States of PSR J1722–3207
Authors: Zhao D. , Yan W. M. , Wang N. , Yuan J. P.
Published: December 2023

We have conducted a detailed study of single-pulse emission from PSR J1722−3207, which was observed at 1369 MHz using the Parkes 64 m radio telescope. PSR J1722−3207 has an asymmetric two-component mean pulse profile. We find that the brighter leading component exhibits a periodic phase-stationary nondrift amplitude modulation while the trailing component remains unchanged. As a result of this, this pulsar switches between a strong state and a weak emission state periodically. Spectral analysis of the fluctuations showed that the modulation period is very short (∼2.0 s or 20P), where P is the rotation period of the pulsar. The polarization properties of the strong and weak states were investigated. The swings in the position angle of the two states are similar, suggesting that their basic emission geometry is the same. At present, it is difficult to explain the periodic mode-changing phenomenon observed in this pulsar with existing subpulse drifting models.
The Formation of Blue Large-amplitude Pulsators from White-dwarf Main-sequence Star Mergers
Authors: Zhang Xianfei , Jeffery C. Simon , Su Jie , Bi Shaolan
Published: December 2023

Blue large-amplitude pulsators (BLAPs) are hot low-mass stars that show large-amplitude light variations likely due to radial oscillations driven by iron group opacities. Period changes provide evidence of both secular contraction and expansion among the class. Various formation histories have been proposed, but none are completely satisfactory. Zhang et al. proposed that the merger of a helium-core white dwarf with a low-mass main-sequence star (HeWD+MS) can lead to the formation of some classes of hot subdwarfs. We have analyzed these HeWD+MS merger models in more detail. Between helium-shell ignition and full helium-core burning, the models pass through the volume of luminosity–gravity–temperature space occupied by BLAPs. Periods of expansion and contraction associated with helium-shell flashes can account for the observed rates of period change. We argue that the HeWD+MS merger model provides at least one BLAP formation channel.

Published: December 2023

The Near-Earth Object Surveyor (NEO Surveyor) mission has a requirement to find two-thirds of the potentially hazardous asteroids larger than 140 m in size. In order to determine the mission’s expected progress toward this goal during design and testing, as well as the actual progress during the survey, a simulation tool has been developed to act as a consistent and quantifiable yardstick. We test that the survey simulation software is correctly predicting on-sky positions and thermal infrared fluxes by using it to reproduce the published measurements of asteroids from the NEOWISE mission. We then extended this work to find previously unreported detections of known near-Earth asteroids in the NEOWISE data archive, a search that resulted in 21,661 recovery detections, including 1166 objects that had no previously reported NEOWISE observations. These efforts demonstrate the reliability of the NEO Surveyor Survey Simulator tool and the perennial value of searchable image and source catalog archives for extending our knowledge of the small bodies of the solar system.

Published: December 2023

Hongze Lake is China’s fourth largest freshwater lake and is also an important habitat for hundreds of thousands of migratory birds on the East Asian-Australian Flyway (EAAF). Sihong Hongze Lake Wetlands National Nature Reserve is located on the northwest of Hongze Lake, Sihong County, Jiangsu Province. The Reserve is a protected large area of natural lake wetlands, marsh wetlands and riverine wetlands and used as a stopover and wintering habitats for migratory birds. Previous studies have conducted bird diversity and temporal-spatial variation in this Reserve, but only for species of Anseriformes. There is still a lack of a comprehensive dataset on the number of bird species and individuals in this Reserve throughout the year. Our study was conducted from July 2020 to June 2021 to observe bird species composition and individual numbers at Sihong Hongze Lake Wetlands National Nature Reserve and provides an occurrence dataset with detailed species and geographic information.

This occurrence dataset is the first public record of birds in Sihong Hongze Lake Wetlands National Nature Reserve for a whole year, which includes the taxonomic information, location information, number, investigation date and endangered level for each species. All data have been published on GBIF.
Exploring new geometric contraction mappings and their applications in fractional metric spaces
Authors: Qawaqneh Haitham , Hammad Hasanen A. , Aydi Hassen
Published: December 2023

This article delves deeply into some mathematical basic theorems and their diverse applications in a variety of domains. The major issue of interest is the Banach Fixed Point Theorem (BFPT), which states the existence of a unique fixed point in fractional metric spaces. The significance of this theorem stems from its utility in a variety of mathematical situations for approximating solutions and resolving iterative problems. On this foundational basis, the study expands by introducing the concept of fractional geometric contraction mappings, which provide a new perspective on how convergence develops in fractional metric spaces.

Authors: Bühler Nolwenn
Published: December 2023

Quelle place pour l’anthropologie en temps de crise sanitaire ? Cet article propose d’aborder cette question en retraçant la naissance et le développement de SociocoViD, un projet d’anthropologie médicale développé dans le cadre d’une collaboration interdisciplinaire avec une équipe d’épidémiologistes et de médecins spécialisés en médecine sociale, dans le Canton de Vaud en Suisse. L’objectif de cet article est de mettre en lumière les différents enjeux méthodologiques, épistémiques et institutionnels que la mise en place du projet a soulevés en documentant les pratiques de l’interdisciplinarité « en train de se faire ». Dans la première partie, je rendrai compte de la réponse des sciences sociales à la pandémie en Suisse. Dans la seconde partie, j’analyserai les modalités de collaboration spécifiques déployées dans ce projet en me concentrant sur l’important travail relationnel et épistémique nécessaire à une démarche interdisciplinaire. En montrant comment l’interdisciplinarité permet de légitimer l’approche anthropologique tout en cadrant la portée de ses analyses, ce projet sert d’étude de cas pour ouvrir une réflexion plus large sur le rôle et la capacité critique de l’anthropologie dans un contexte de crise sanitaire.

Cet article s’intéresse à la fragilité matérielle des scellés biologiques dont les contenus peuvent faire l’objet d’analyses génétiques dans le cadre de l’élucidation d’affaires non résolues. Il explore le travail de problématisation, de production de connaissances et de responsabilisation des acteurs de la chaîne criminalistique vis-à-vis de la contamination et de la dégradation des matières qui composent les scellés et leurs contenus. L’article montre la dualité de ces deux phénomènes, à la fois appuis et menaces pour la criminalistique. Cette dualité se manifeste dans le traitement des scellés en choses fragiles, qui suppose de connaître et d’agir sur la contamination et la dégradation tout en « faisant avec », et ce afin de préserver la preuve ADN le jour où le pouvoir judiciaire voudrait la mobiliser. L’article montre que ce traitement des scellés peut être analysé comme leur préparation pour un futur à l’état de « virtualité », à l’intersection du temps des matières et du temps judiciaire.
Online Learning Changed the Learning Motivation
Authors: Khumalo Njabulo
Published: December 2023

Transitioning from contact to online learning has been highly complex for institutions of higher learning globally. One of the less discussed areas of online learning is the student's need for motivation as the leading players in the process. The chapter focuses on learning about preferences of learning, physical equipment and printed documents, home facilities and disturbance, social engagement, focus and confusion, limited space, time, emotional issues, employment, and supporting material as challenges to students' academic motivation. Further developed a higher education needs for students on the online learning (HENSOL) framework that reveals the needs for students and online learning and provides recommendations to those in power, especially in the higher education sector. Some of the recommendations are to invest more in learning platforms that are more efficient and less cost-effective to enhance a culture of synchronizing learning by ensuring that study material is available 24/7 for students wherever they are.

Spiritual Intelligence and Srimad Bhagavad Gita
Authors: Subramaniam Srividya
Published: December 2023

Most explanations of human behaviour as we know today come from the foundations of philosophers and mystics of Western traditions. In spite of any number of explanations, human miseries and sufferings continue to increase and there is an exponential growth of mental health issues. The present chapter has tried to understand how Vedic philosophy, especially Srimad Bhagavad Gita, offers a panoramic view on the functioning of human mind and its sufferings. Among the eighteen chapters of Srimad Bhagavad Gita, the author has chosen chapter two, consisting of 72 verses, which in detail talks about the Sankhya Yoga or dualistic realism. The reason for choosing the same has also been explained. A thematic analysis of the seventy-two verses and its commentaries resulted in six themes. The chapter concludes with the concept called “Sthitaprajñasamādhistha” or, “state of steady intelligence situated in a trance,” which is a practice every human being should strive to relief themselves of all miseries and sufferings of human life and attain a state of permanent happiness.

Corporate Learners' Perceptions of Extended Reality Technology as a Learning Aid in the Workplace
Authors: Shirley Ho Xue Li , Lee Kean Wah
Published: December 2023

Virtual and augmented reality have grown in popularity as learning tools in the workplace in recent years. This study looks at how corporate learners perceive the use of extended reality technology in the workplace. Corporate learners utilise a variety of learning technologies, and their opinions of these resources have an impact on their adoption and learning process. A mixed-methods study was conducted using an online survey and follow-up interviews with the financial services participants (N = 106). The study was guided by the second-generation activity theory and the technology acceptance model (TAM). Findings showed that learners valued immersive technology because it increased teammate involvement and knowledge. However, issues with technological accessibility and incorporation into corporate learning programmes were also raised. According to this study, immersive technology may help with workplace learning, but its advantages and challenges should be taken into account as well. Extended reality (XR) technology offers notable advantages in learning by elevating enjoyment and facilitating a smoother learning experience, which greatly impacts learners' attitudes. However, its implementation in education presents challenges, primarily due to the increased need for resources. Additionally, the learning curve associated with XR technology poses hurdles for both educators and learners. Limited accessibility to virtual reality gear further complicates matters, potentially hindering proficiency and accessibility for learners trying to navigate this technology.
Cutting Edge: STING Induces ACLY Activation and Metabolic Adaptations in Human Macrophages through TBK1

The 2′3′-cyclic GMP-AMP (cGAMP) synthase (cGAS)–stimulator of IFN genes (STING) pathway can sense infection and cellular stress by detecting cytosolic DNA. Upon ligand binding, cGAS produces the cyclic dinucleotide messenger cGAMP, which triggers its receptor STING. Active STING initiates gene transcription through the transcription factors IFN regulatory factor 3 (IRF3) and NF-κB and induces autophagy, but whether STING can cause changes in the metabolism of macrophages is unknown. In this study, we report that STING signaling activates ATP-citrate lyase (ACLY) by phosphorylation in human macrophages. Using genetic and pharmacologic perturbation, we show that STING targets ACLY via its prime downstream signaling effector TANK (TRAF family member–associated NF-κB activator)-binding kinase 1 (TBK1). We further identify that TBK1 alters cellular metabolism upon cGAMP treatment. Our results suggest that STING-mediated metabolic reprogramming adjusts the cellular response to DNA sensing in addition to transcription factor activation and autophagy induction.

Published: December 2023

The enhanced paper grip test (EGPT) quantitatively assesses lower limb strength. EGPT assesses the hallux grip force by reacting a pulling force derived from a card, being positioned underneath the participant's hallux. This study aimed to investigate the repeatability and clinical applicability of the EPGT for assessing foot muscle strength. EPGT force was measured using a dynamometer. The reliability of the measurement of EPGT force was assessed by having two examiners performing the test on the same group of healthy adults. Clinical applicability was assessed in community-dwelling adults of both genders. EPGT force was recorded for both feet using the same standardised protocol for all participants. Regarding reliability, 20 healthy adults aged 23.04±5.5 years participated in the present study. The EGPT demonstrated good to excellent test-retest (ICC1,2 0.8 to 0.86) and interrater reliability (ICC1,2 0.82 to 0.88). A convenience sample of 15 community-dwelling adults (71.6±7.8 years, 68.5% women) was recruited for clinical applicability testing. All participants performed the test with mean score 15±5.7 N. EPGT is a reliable measurement of the hallux grip force strength and can be used for clinical and research purposes.

Onomastics and destiny: Óláfr Pái Hǫskuldsson and family (Laxdæla saga)
Authors: Sayers William
Published: December 2023

The Icelandic chieftain Óláfr Hǫskuldsson of Laxdæla saga is the son of an enslaved Irish princess, Melkorka, yet is still judged a candidate to succeed her father as an Irish king. His choice to return to Iceland is validated by his subsequent success as a stockman and community leader. Yet he fails to recognize that the source of his prosperity and material plenty lies in his maternal inheritance, in which Melkorka (‘Smooth-Oat’) may be identified as a Celtic sovereignty figure, the source of his irrecusable election to a rich somatic life and chieftaincy, complemented by the attention of his paternal family’s tutelary spirit or fylgja. By slaughtering his totemic ox, Harri, he calls down the vengeance of the Icelandic tutelary figure representing his father’s family’s fortunes which had concurrently assured his success. Retribution follows later in the saga with the death of his favourite son, Kjartan. From the perspective of the thirteenth century, when Iceland yielded to Norwegian hegemony, the arc of Óláfr’s career is paralleled on a greater scale by Iceland’s early medieval history.
Effects of habitat heterogeneity on bird communities in the forests of northeastern Germany
Authors: Sommer Robert , Fichtner Andreas
Published: December 2023

Habitat heterogeneity is a key factor for regulating biodiversity in temperate lowland forests. Specifically, stands associated with late forest development phases provide important habitat structures for many rare and threatened forest bird species. However, how forest stands that differ in their structural complexity, canopy conditions and tree species composition affect forest bird assemblages both at the local and landscape scale remains largely unclear. In a young moraine lake landscape of northeastern Germany, we assessed correlations of bird diversity and bird composition with stand properties. We used data from 48 transects (400 m) established in (1) unmanaged, closed-canopy, mature stands that were dominated by Fagus sylvatica (UDS), and (2) diverse managed, mixed coniferous stands with a mosaic of open and closed canopy patches (MCS). We found that bird communities of the UDS strongly differed from those in the MCS, with open habitat species being more frequent in the MCS. By contrast, differences in diversity measures were less distinct. Moreover, we identified nine indicator species for the UDS (Columba oenas, Cyanistes caeruleus, Muscicapa striata, Leiopicus medius, Certhia brachydactyla, Ficedula parva, Dryobates minor, Sturnus vulgaris, Ficedula hypoleuca) and seven indicator species for the MCS (Periparus ater, Pyrrhula pyrrhula, Regulus regulus, Prunella modularis, Lophophanus cristatus, Emberiza citronella, Anthus trivialis). Several famous ancient beech forest patches in Müritz National Park and the UNESCO Biosphere Reserve “Schorfheide-Chorin” were found to harbour the set of the UDS indicator species. The UDS support of bird coenosis is typical for old mature broadleaved forests and can be considered as an effective tool for bird conservation. Our results further indicate that the combination of unmanaged and managed stands associated with different habitat complexities would benefit forest bird assemblages at the landscape scale.

Published: December 2023

Cognitive Decline is a significant cognitive decline from normal cognition to dementia, so interventions are needed to inhibit the development of cognitive decline so that cognitive function does not decline (Smith & Blumenthal, 2016). Various efforts can be made to prevent the decline in cognitive function, namely by pharmacological and non-pharmacological collaborative therapy. Cognitive Stimulation Therapy (CST) is a non-pharmacological therapy that is effective in specifically improving cognitive function and increasing independence, reducing depression, and improving the quality of life of the elderly with dementia. The purpose of this study was to assess the Effectiveness of the Application of Cognitive Stimulation Therapy (CST) to Improve Cognitive Function, Activity Daily living, Psychological (reducing depression), and Quality of Life. This was quasi-experimental study with Two Group (pre-test and post-test), the inclusion criteria was: elderly over 60 years old with mild to moderate dementia. Therapy was carried out in 14 sessions in intervention groups, held 2 times a week for 7 weeks with a duration of 40-45 minutes. The results showed a significant difference between the pre-test and post-test in the intervention group and the control group in 3 domains, namely cognitive function p-value (0.029), depression p-value (0.02) and quality of life p-value (0.03). It was found that there was cognitive stability and an increase in the number of scores before and after the intervention, a decrease in depression and an increase in quality of life. Suggestions for this study are expected to provide CST intervention is one of the activities that can be applied in the geriatric service unit for dementia patients.

Education is considered the most strategic field for realizing national welfare. Therefore, students' comfort in learning and ease of access to education must be guaranteed because this is the first step in helping to realize national welfare. Many factors can affect a student's learning outcomes, one of which is inadequate infrastructure. This research aims to explore the influence of infrastructure on student learning continuity. This research uses a qualitative approach with a descriptive method. Data was collected using interview and observation techniques. The results show that infrastructure is indeed proven to affect student learning outcomes and in realizing equitable development in this aspect of education there are still challenges that continue to arise, such as lack of funding. Therefore, this study recommends that the central government can focus the state budget in terms of education budget to equalize access to education in Indonesia and realize the creation of national welfare and a superior golden generation.

This research examines how environmental movement in Indonesia was formed using the experience of the Indonesian Forum for Environment (WALHI) in facing challenges such as the situation of ecological crisis and increasing environmental damage, the political situation and the situation of civil society and certainly affects the future strategy of the environmental movement. The research uses an organizational phase approach to see the environment movement dynamic from pioneering into associative phase for 40 years of the environmental movement presented by WALHI. Data collection was carried out through interviews, activists’ reflections, informal conversations and by being present at various occasions. This research is a reflective process for the environmental movement, in determining strategic choices to support advocacy work and saving the environment, as well as expanding the environmental movement in Indonesia. As the largest environmental organization in Indonesia, WALHI has provided a role and influence in building and strengthening the environmental movement as well as setting an environmental reform agenda and framing environmental issues as a collective responsibility.

This research aims to understand the development of rice imports, the factors driving rice imports, the impact of rice imports, and steps to increase production and reduce rice imports in Indonesia. This research uses a descriptive qualitative approach. Data collection uses secondary data from CNBC Indonesia YouTube news videos and rice import data from the Central Statistics Agency. The data analysis technique uses the Interactive Model from Miles et al. (2014). The research results show that based on data recorded at the Central Bureau of Statistics, Indonesia imported rice from 2000-2023 to maintain availability, strengthen rice reserves, anticipate El Nino events, and increase population. The impact of rice imports is to maintain the situation's stability, but if the policy is inappropriate, it can harm domestic farmers. Efforts that the government can make to increase production and reduce rice imports include implementing the steps successfully implemented by Cambodia, immediately creating a program to increase rice production, and focusing more on intensifying land productivity increases.

The teachers' strategies in the classroom are more adequate if the students' learning styles are known. The objective of this research was to apply the Honey - Alonso questionnaire for the characterization of learning styles in higher basic education students. The methodology applied was non-experimental, descriptive, explanatory, and fieldwork. The approach was quantitative, with a KR20 reliability of 0.878. The population sample consisted of 119 students, and the SPSS V.23 and Excel programs were used to process the information. The results indicated that the theoretical style is predominant. Knowing the learning style will allow teachers to design didactic strategies that encourage practical activity when choosing a career in the technical baccalaureate.

A system of nonlinear ordinary differential equations of large dimension with a parameter
is considered. We investigate asymptotic properties of solutions to the system in dependence on the growth of the number of the equations or parameter. We prove that, for sufficiently large number of differential equations, the last component of the solution to the Cauchy problem is an approximate solution to an initial problem for one delay differential equation. For a fixed number of equations and a sufficiently large parameter, the solution to the Cauchy problem for the system is an approximate solution to the Cauchy problem for a simpler system.

We consider a linear differential game with an impulse control of the first player. The capabilities of the first player are determined by the stock of resources that he can use to form his control. The control of the second player is subject to a geometric constraint. The vectograms of the players are described by the same ball with different time-dependent radii. It is believed that the second player at a time moment unknown in advance to the first player can change his dynamics once. The terminal set is a ball with a fixed radius. The goal of the first player is to lead the phase vector to the terminal set at a given time. The goal of the second player is the opposite. Necessary and sufficient conditions for a meeting the terminal set at the given time are found. The corresponding controls of the players, guaranteeing the achievement of their goals are constructed.

By the aid of Appell, Humbert and Bessel functions, the integral representations for a Kamp´e de F´eriet function are found. The validity of integral representations for a Kamp´e de F´eriet function of general form are proved. Conditions, under which these representations are expressed in terms of products of two generalized hypergeometric functions are found. Examples, in which the integral representation of the Kamp´e de F´eriet function containing Appell, Humbert or Bessel functions, are identified.
