Revisiting Collisional Dust Growth in Class 0/I Protostellar Disks: Sweep-up Can Convert a Few 10 M
⊕ of Dust into Kilogram Pebbles in 0.1 Myr
Authors: Xu Wenrui , Armitage Philip J.
Published: April 2023

Recent observations suggest that the first stages of planet formation likely take place in the Class 0/I phase of young stellar object evolution, when the star and the disk are still embedded in an infalling envelope. In this study we perform grain coagulation calculations to investigate the very first stage of planet formation, the collisional growth of dust grains, in Class 0/I disks. We find that the slow increase in grain mass by high-velocity collision with much smaller grains (“sweep-up”) allows ∼50 M
⊕ of grains to grow well beyond the fragmentation barrier into ∼kilogram pebbles by the end of Class 0/I (0.1 Myr). We analyze the linear growth and saturation of sweep-up to understand our results quantitatively, and test whether the sweep-up outcome is sensitive to disk parameters and details of the grain coagulation model. The sweep-up pebble population could be important for planet formation, because they are less well-coupled to the gas (compared to the main population below the fragmentation barrier) and therefore more favorable to known mechanisms of dust clump formation (which initiate planetesimal formation). It also contains enough mass to form all planet cores, based on observational estimates of the planet mass budget. Our findings motivate future studies of grain growth and planetesimal formation in Class 0/I disks, including the subsequent evolution of this sweep-up population.
Constraints From Dwarf Galaxies on Black Hole Seeding and Growth Models With Current and Future Surveys
Authors: Chadayammuri Urmila , Bogdán Ákos , Ricarte Angelo , Natarajan Priyamvada
Published: April 2023

Dwarf galaxies are promising test beds for constraining models of supermassive and intermediate-mass black holes (MBHs) via their BH occupation fraction (BHOF). Disentangling seeding from the confounding effects of mass assembly over a Hubble time is a challenging problem that we tackle in this study with a suite of semianalytical models (SAMs). We show how the measured BHOF depends on the lowest BH mass or active galactic nucleus (AGN) luminosity achieved by a survey. To tell seeding models apart, we need to detect or model all AGNs brighter than 1037 erg s−1 in galaxies of M
* ∼ 108−10
M
⊙. Shallower surveys, like eRASS, cannot distinguish between seed models even with the compensation of a much larger survey volume. We show that the AMUSE survey, with its inference of the MBH population underlying the observed AGNs, strongly favors heavy seed models, growing with either a power-law Eddington ratio distribution function or one in which BH accretion is tied to the star formation rate (i.e., the AGN-main sequence, AGN-MS, model). These two growth channels can then be distinguished by the AGN luminosity function at >1040 erg s−1, with the AGN-MS model requiring more accretion than observed at z ∼ 0. Thus, current X-ray observations favor heavy seeds whose Eddington ratios follow a power-law distribution. The different models also predict different radio scaling relations, which we quantify using the fundamental plane of BH activity. We close with recommendations for the design of upcoming multiwavelength campaigns that can optimally detect MBHs in dwarf galaxies.

, OH+, and H2O+, are hard to detect and require the presence of background massive stars for absorption measurements. In this work, we propose an alternative method to infer the CRIR in diffuse clouds using the abundance ratios of OH/CO and HCO+/CO. We have analyzed the response of chemical abundances of CO, OH, and HCO+ on various environmental parameters of the interstellar medium in diffuse clouds and found that their abundances are proportional to ζ
2. Our analytic expressions give an excellent calculation of the abundance of OH for ζ
2 ≤ 10−15 s−1, which are potentially useful for modeling chemistry in hydrodynamical simulations. The abundances of OH and HCO+ were found to monotonically decrease with increasing density, while the CO abundance shows the opposite trend. With high-sensitivity absorption transitions of both CO (1–0) and (2–1) lines from Atacama Large Millimeter/submillimeter Array, we have derived the H2 number densities (

) in the Great Observatories Origins Survey Northern field in the redshift range z = 0.40–0.75. We use two AstroSat/UVIT (N242W, N245M) bands, two Hubble Space Telescope (F275W, F336W) bands, and a KPNO (U) band to sample the UV continuum slope of selected galaxies between 1215 and 2600 Å. The mean (median) and 1σ scatter in the observed β are found to be −1.33 ± 0.07 ( − 1.32) and 0.60 within the considered redshift range. We do not find any significant evolution in the mean β within our redshift window. Our measurements add new data points to the global β–z relation in the least-explored redshift regime, further reinforcing the gradual reddening of galaxy UV continuum with cosmic time. We notice no strong consistent trend between β and M

1500 < − 15 mag. However, the majority of the most-luminous galaxies (M

We present an analysis of the BVRI photometry of the blazar BL Lacertae on diverse timescales from 2020 mid-July to mid-September. We have used 11 different optical telescopes around the world and have collected data over 84 observational nights. The observations cover the onset of a new activity phase of BL Lacertae that started in 2020 August (termed as the 2020 August flare by us), and the analysis is focused on the intranight variability. On short-term timescales, (i) flux varied with ∼2.2 mag in the R band, (ii) the spectral index was found to be weakly dependent on the flux (i.e., the variations could be considered mildly chromatic), and (iii) no periodicity was detected. On intranight timescales, BL Lacertae was found to predominantly show bluer-when-brighter chromatism. We also found two cases of significant interband time lags of the order of a few minutes. The duty cycle of the blazar during the 2020 August flare was estimated to be quite high (∼90% or higher). We decomposed the intranight light curves into individual flares and determined their characteristics. On the basis of our analysis and assuming the turbulent jet model, we determined some characteristics of the emitting regions: Doppler factor, magnetic field strength, electron Lorentz factor, and radius. The radii determined were discussed in the framework of the Kolmogorov theory of turbulence. We also estimated the weighted mean structure function slope on intranight timescales, related it to the slope of the power spectral density, and discussed it with regard to the origin of intranight variability.

We report the characterization of 28 low-mass (0.02 M
⊙ ≤ M
2 ≤ 0.25 M
⊙) companions to Kepler objects of interest (KOIs), eight of which were previously designated confirmed planets. These objects were detected as transiting companions to Sunlike stars (G and F dwarfs) by the Kepler mission and are confirmed as single-lined spectroscopic binaries in the current work using the northern multiplexed Apache Point Observatory Galactic Evolution Experiment near-infrared spectrograph (APOGEE-N) as part of the third and fourth Sloan Digital Sky Surveys. We have observed hundreds of KOIs using APOGEE-N and collected a total of 43,175 spectra with a median of 19 visits and a median baseline of ∼1.9 yr per target. We jointly model the Kepler photometry and APOGEE-N radial velocities to derive fundamental parameters for this subset of 28 transiting companions. The radii for most of these low-mass companions are overinflated (by ∼10%) when compared to theoretical models. Tidally locked M dwarfs on short-period orbits show the largest amount of inflation, but inflation is also evident for companions that are well separated from the host star. We demonstrate that APOGEE-N data provide reliable radial velocities when compared to precise high-resolution spectrographs that enable detailed characterization of individual systems and the inference of orbital elements for faint (H > 12) KOIs. The data from the entire APOGEE-KOI program are public and present an opportunity to characterize an extensive subset of the binary population observed by Kepler.
GTasb3D: A Novel 3D Framework for Modeling Thermal Evolution and Rarefied Flows in Porous Active Small Bodies with Various Shapes
Authors: Zhang Yun , Hartzell Christine M.
Published: April 2023

Volatiles in small bodies provide important clues to solar system evolution and are of in-situ-resource-utilization interest. Explicit modeling of small bodies’ global thermophysical process is essential to assess volatiles’ evolution and abundance. Previous numerical studies commonly use a finite difference/volume method, which has limited capability in simulating the interior thermal dynamics of small bodies with realistic shapes. Here we developed a novel 3D framework using the generalized finite difference method for modeling thermal evolution of active small bodies (GTasb3D). By fully solving the energy and mass conservation equations using a mesh-free, Cartesian-coordinate-based method, this framework can evaluate the heat and mass transport in a porous cometary body of various shapes. Several tests and comparisons with previous studies have been carried out to verify this framework's accuracy and efficiency. We show that the timescale to achieve thermal equilibrium and the global temperature distribution are in good agreement with previous theoretical and numerical estimates. The GTasb3D simulations show that ice sublimation mainly occurs near the ice front, and parts of the resulting vapor recondense beneath the ice front. The surface gas density dramatically decreases as the ice retreats. For a 1 km radius object located at 3 au with initially homogeneous dust-ice distribution, the depth to ice at the equator is >∼2 cm after ∼10 yr, assuming that a dust mantle is left behind after ice depletion. At this stage, the global gas production rate is below the gas emission detection capability but is capable of lifting submillimeter-sized dust from the nucleus’s near-subsurface.
De la littérature pour développer un regard soignant : l’apport du roman « Réparer les vivants »
Authors: Vonarx Nicolas
Published: April 2023

L’intégration des humanités dans les formations en sciences de la santé est un moyen d’humaniser les pratiques soignantes. Des sciences humaines et sociales, mais aussi plusieurs médias artistiques, dont la danse, le cinéma, le théâtre et la littérature permettent notamment de rendre compte de la complexité des expériences vécues et d’approfondir la notion de soin. Dans ce texte, nous revenons sur la place et l’utilité de la littérature dans l’enseignement des soignants. Nous proposons d’analyser le roman de Maylis de Kerangal, «  Réparer les vivants  », qui porte sur le prélèvement d’organes, pour montrer comment ce type de contenu peut aider à approfondir le regard des soignants. Toujours soutenu par le texte comme si ce dernier était un matériel anthropologique récolté sur un terrain, nous ouvrons des portes à faire des thèmes à fortes valeurs phénoménologiques, éthiques, politiques et anthropo-sociologiques, qui pourraient être des lieux de rencontres et de réflexions pédagogiques.
Faut-il une conversion écologique de l’agir politique ?
Authors: Boissier Fabrice
Published: April 2023

Pour répondre aux défis de la transition écologique, il faut une transformation profonde de l’agir politique. Mais le terme de conversion est-il adéquat pour décrire cette transformation ? Les appels des prophètes à la conversion politique peuvent nous inspirer, à condition de les transposer de manière analogique au contexte moderne. La conversion peut alors être comprise comme la réorientation de l’agir politique lorsqu’il n’est plus aligné avec le bien commun.
La « conversion écologique » : un concept pas si évident en éthique
Authors: Lesch Walter
Published: April 2023

La contribution cherche à comprendre la fascination pour l’idée d’une conversion écologique qui semble être tellement évidente et reste malgré tout confrontée à une réalité peu favorable à un tel discours et à un véritable changement de comportement. L’utilisation du mot « conversion » évoque un champ sémantique complexe et contaminé, notamment dans le contexte de la communication religieuse. Si l’éthique théologique ne veut pas se contenter de l’exégèse des encycliques, elle doit entrer dans une analyse plus critique des niveaux de l’exhortation, de la motivation et de l’argumentation en dialogue avec les sciences humaines. Une éthique théologique compréhensible et crédible est appelée à sortir de sa bulle convictionnelle pour que l’idée noble d’une conversion écologique devienne opérationnelle.
Human-like car-following modeling based on online driving style recognition
Authors: Ma Lijing , Qu Shiru , Song Lijun , Zhang Junxi , Ren Jie
Published: April 2023

Incorporating human driving style into car-following modeling is critical for achieving higher levels of driving automation. By capturing the characteristics of human driving, it can lead to a more natural and seamless transition from human-driven to automated driving. A clustering approach is introduced that utilized principal component analysis (PCA) and k-means clustering algorithm to identify driving style types such as aggressive, moderate and conservative at the timestep level. Additionally, an online driving style recognition technique is developed based on the memory effect in driving behavior, allowing for real-time identification of a driver's driving style and enabling adaptive control in automated driving. Finally, the Intelligent Driver Model (IDM) has been improved through the incorporation of an online driving style recognition strategy into car-following modeling, resulting in a human-like IDM that emulates real-world driving behaviors. This enhancement has important implications for the field of automated driving, as it allows for greater accuracy and adaptability in modeling human driving behavior and may ultimately lead to more effective and seamless transitions between human-driven and automated driving modes. The results show that the time-step level driving style recognition method provides a more precise understanding of driving styles that accounts for both inter-driver heterogeneity and intra-driver variation. The proposed human-like IDM performs well in capturing driving style characteristics and reproducing driving behavior. The stability of this improved human-like IDM is also confirmed, indicating its reliability and effectiveness. Overall, the research suggests that the proposed model has promising performance and potential applications in the field of automated driving.
Results on monochromatic vertex disconnection of graphs
Authors: Fu Miao , Zhang Yuqin
Published: April 2023

Let $ G $ be a vertex-colored graph. A vertex cut $ S $ of $ G $ is called a monochromatic vertex cut if the vertices of $ S $ are colored with the same color. A graph $ G $ is monochromatically vertex-disconnected if any two nonadjacent vertices of $ G $ have a monochromatic vertex cut separating them. The monochromatic vertex disconnection number of $ G $, denoted by $ mvd(G) $, is the maximum number of colors that are used to make $ G $ monochromatically vertex-disconnected. In this paper, the connection between the graph parameters are studied: $ mvd(G) $, connectivity and block decomposition. We determine the value of $ mvd(G) $ for some well-known graphs, and then characterize $ G $ when $ n-5\leq mvd(G)\leq n $ and all blocks of $ G $ are minimally 2-connected triangle-free graphs. We obtain the maximum size of a graph $ G $ with $ mvd(G) = k $ for any $ k $. Finally, we study the Erdős-Gallai-type results for $ mvd(G) $, and completely solve them.

(Re-)defining “animal magnetism”: the mesmerism investigations of 1784
Authors: Conickx Chloé
Published: April 2023

Une historiographie plus ancienne a appréhendé les enquêtes de 1784 sur le « magnétisme animal » comme le triomphe scientifique de la méthode expérimentale. Cet article va réévaluer la portée et l’impact de ces enquêtes et défendre l’idée que les membres des commissions ont altéré le sens de « magnétisme animal » pour convenir à leurs propres objectifs et intérêts. Plus spécifiquement, je vais montrer comment leurs expériences ont traduit leurs interprétations propres du sens, de la définition et de la fonction thérapeutique du magnétisme animal, et comment ces interprétations étaient constamment réévaluées et redéfinies. En premier lieu, je vais discuter de la manière dont les membres des commissions ont fait des sensations les effets visibles principaux du magnétisme. En deuxième lieu, je vais montrer comment les expériences ont appliqué des critères de démarcation sociale aux sensibilités des sujets. En troisième lieu, je vais présenter comment ils ont amélioré la définition de leurs protocoles pour s’assurer de la crédibilité de leur hypothèse selon laquelle l’imagination produisait les sensations magnétiques. Enfin, je vais expliquer comment ils ont redéfini en convulsions les « crises » magnétiques, afin de saper la légitimité de la thérapie.
Réception, diffusion et déclinaisons du mesmérisme dans l’Amérique postrévolutionnaire et la jeune République étatsunienne
Authors: Narvaez Auréliane
Published: April 2023

Sujets de conversations et de débats dès les années 1780, le magnétisme animal et les théories de Mesmer rencontrent aux États-Unis un accueil initialement mitigé, oscillant entre amusement et scepticisme, parfois même jusqu’à la défiance. Dans une jeune nation tout juste émancipée de l’influence britannique et encore incertaine quant aux manières d’incarner et de pérenniser ses idéaux fondateurs de liberté et d’indépendance, les concepts attachés au magnétisme, comme la manipulation, l’emprise ou l’altération des sens, connaissent une réception plus que réservée. Il faut attendre la fin des années 1820 pour que le mesmérisme trouve un terreau favorable à son développement outre-Atlantique. Cette implantation différée est due à plusieurs facteurs. Le contexte géopolitique conflictuel, à la charnière des xviiie et xixe siècles, place tout d’abord les États-Unis dans une position inconfortable envers l’Europe et génère un climat de méfiance, voire d’antagonisme préjudiciable aux circulations transatlantiques. À l’inverse, l’écosystème réformateur de la jeune République, la libéralisation du paysage religieux et l’accélération des échanges entre 1830 et 1850 vont concourir à l’épanouissement d’une variante étatsunienne du mesmérisme, conçue comme science de l’expérience religieuse, entre revendication à penser librement et invocation de la modernité.
Leo Gershoy, vecteur ukraino-américain de l'historiographie de la Révolution
Authors: Bouyssy Maïté
Published: April 2023

L’intérêt de faire entrer Leo Gershoy dans les échanges franco-américains de l’historiographie de la Révolution française est de prendre, dès les années 1925, un prisme doublement décalé des autorités et conventions parisiennes à partir de son travail sur Bertrand Barère, dont il fut et reste le biographe majeur. Il qualifie le personnage d’« unheroic » puis, en 1962, dans un dernier ouvrage, de « reluctant terrorist », au fil d’une lecture non strictement idéologique du fait partisan et de la pratique du pouvoir en révolution. Sa sensibilité à un marxisme dissident, celui des anarcho-russes des États-Unis, renforcé de son origine de juif ukrainien parti enfant de Kryvyi-Rih (Krivoï-Rog) le mènent à considérer l’exercice de l’exécutif et sa légitimité face à la questions cruciale de ce qui fait nation en situation de guerre pour 1917-1921, puis sous le surplomb dirimant des camps en présence après la Seconde Guerre mondiale, suivie de la Guerre froide. Le souci souterrain de comprendre les hésitations et compromis, le statut de l’adversaire, minorité politique, mais on pourrait ajouter religieuse ou ethnique, fondent une curiosité et des choix de chantiers dont le personnage de Bertrand Barère est le révélateur.

The sustainable development goals are a fundamental framework for universities that want to extend their impact. Not only to education but also transversally into all of the agenda 2030 advocating the well-being of the people. The students are capable of creating sustainable and innovative solutions while building a close bond with the local and international community. MERCOSUR universities, in this complex world, can be benefited in two-ways. First, as part of a solution to social problems with a sustainable development approach and, lately, as part of raising the awareness to the competition of the agenda 2030. This chapter aims to contribute to research and practice fostering discussions and sharing knowledge about the importance that the sustainable development goals have in the students of the MERCOSUR.
Assessment of Bare Soil in Extensive Livestock Areas in the Southwest of the Iberian Peninsula by Multi-Temporal Orthophotographs (2002-2016)
Authors: Torreño Alberto Alfonso , Barrena-González Jesús , Lozano-Parra Javier , Garrido-Velarde Jacinto
Published: April 2023

Mediterranean savannahs, “dehesas,” are an agro-silvo-pastoral land use system in the southwest of Iberian Peninsula where the extensive livestock farming is the main land use. This study analyzes the evolution of bare soil in two different farms with an agro-silvo-pastoral system located in Extremadura (Spain). The main objective was to study the relationship between rainfall and land management with the surface of bare soil in the dehesas. Evolution of annual and monthly rainfall in the study areas from 2001 to 2017 was analyzed. The main findings showed that a lack of rainfall during three months combined with an increase in the livestock density had repercussions in the presence of a greater surface of bare soil in the dehesas. The distribution of livestock in specific areas (for example, ponds or feed troughs) limited grass growth and favored the development of permanent livestock paths. Therefore, new trends in regenerative livestock management combined with a sustainable use of the dehesa ecosystem may be a key to lessen this problem.
The Landless, Displaced, and “Crisis”
Authors: Bag Akash
Published: April 2023

This chapter's objective is to examine the phenomenon of climate migration using the theories of securitization, externalization of borders, and analysis of world systems. By examining the opportunities and barriers related to the issue, the chapter attempts to explain how circumstances and structures have restricted the rights of climate refugees in the contemporary international system. The world system analysis discusses the underlying principles of the present world system; how they have led to climate migration, and how they have also been responsible for governments' desires to maintain their sovereignty. Implementing various procedures, such as the externalization of borders to stop the fictitious threat that climate refugees are perceived as, has resulted in the securitization of migration, which the world system analysis can explain. The chapter draws conclusions based on history and recent events to shed light on the question of what role climate refugees play in the current global order.
Analysis of the Impact of Artificial Intelligence in Enhancing Human Resources Practices
Authors: Genç Sema Yilmaz
Published: April 2023

Artificial intelligence, in a larger sense, refers to computers that have human intelligence-specific capabilities such as obtaining information, perceiving, seeing, thinking, and making decisions. At first glance, artificial intelligence, often known as “artificial intelligence” (AI) in the literature, causes everyone to associate something distinct. According to research, the concept of artificial intelligence evokes an electro-mechanical robot replacing human beings, but everyone involved in this field is aware that there is a definite difference between human beings and machines. The aim of this article is to show the importance of using AI in today's HR practices. In this context, one of the qualitative research designs, phenomenological research, was deemed 1appropriate for the thesis study. Because phenomenology establishes a framework for exploring subjects that aren't utterly unfamiliar but whose meaning isn't quite clear.

Published: April 2023

The customization of the intervention using patient feedback is an evidence-based practice aimed at the continuous evaluation, during the course of treatment, of the patient's change at a clinical level. There are few easy-to-use tools for common assessment of psychological distress, designed to be used for screening and during treatment to monitor progress. The CORE-10 is definitely one of them. Thus, the aim of the present study was to examine the psychometric properties of the Italian version of the Clinical Outcomes in Routine Evaluation - 10 (CORE-10). A sample of 548 participants (females, N = 463, 84,5%; mean age 23.29 ± 7.21 years) was recruited in the study and filled out a battery of measures. The internal validity of the CORE-10 was investigated through a confirmatory factor analysis (CFA) which evidenced a good fit to the data, suggesting a unidimensional factorial structure of the measure. Further, the scale had a good internal reliability and was significantly associated with other measures of distress, interpersonal problems, wellbeing, and insecure attachment. Finally, it showed excellent diagnostic accuracy, as well as intrinsic and post-test diagnostics. Given its validity and reliability, the CORE-10 may be adopted by Italian-speaking psychotherapists and researchers to evaluate the outcomes of mental health interventions as well as to track the session-to-session changes over time in psychological distress among patients.

Background: Remote ischemic postconditioning (RIPoC) is induced by several cycles of brief, reversible, mechanical blood flow occlusion, and reperfusion of the distal organs thereby protecting target organs. We investigated if RIPoC ameliorated liver injury in a lipopolysaccharide (LPS)-induced endotoxemic rats.Methods: Protocol 1) Rats were administered LPS and samples collected at 0, 2, 6, 12, and 18 h. 2) After RIPoC at 2, 6, and 12 h (L+2R+18H, L+6R+18H, and L+12R+18H), samples were analyzed at 18 h. 3) RIPoC was performed at 2 h, analysis samples at 6, 12, 18 h (L+2R+6H, L+2R+12H, L+2R+18H), and RIPoC at 6 h, analysis at 12 h (L+6R+12H). 4) Rats were assigned to a control group while in the RIPoC group, RIPoC was performed at 2, 6, 10, and 14 h, with samples analyzed at 18 h. Results: Protocol 1) Liver enzyme, malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), and nuclear factor-κB (NF-κB) levels increased while superoxide dismutase (SOD) levels decreased over time. 2) Liver enzyme and MDA levels were lower while SOD levels were higher in L+12R+18H and L+6R+18H groups when compared with L+2R+18H group. 3) Liver enzyme and MDA levels were lower while SOD levels were higher in L+2R+6H and L+6R+12H groups when compared with L+2R+12H and L+2R+18H groups. 4) Liver enzyme, MDA, TNF-α, and NF-κB levels were lower while SOD levels were higher in RIPoC group when compared with control group.Conclusions: RIPoC attenuated liver injury in the LPS-induced sepsis model by modifying inflammatory and oxidative stress response for a limited period.

Published: April 2023

Severe acute respiratory syndrome-CoV-2 infection has been known to cause an array of chronic consequences, most of which are yet to be studied in detail. These presentations are due to direct invasion of the tissues by the virus or other factors such as immune response to the virus. These sequelae affect the patient’s quality of life implicating the importance of follow-up care in all coronavirus disease-2019 (COVID-19) patients and changing the definition of “post-COVID-19 recovery.” Adequate preparedness for post-COVID consequences with adequate health care is need of the hour. This also warrants for the patients’ awareness, stressing upon the importance of educating the general public about keeping a watch for certain symptoms. Regular screening procedures may also aid in timely prevention, recognition, and management hence reducing morbidity and mortality in the post-COVID phase.

Published: April 2023

Background:

Laparoscopic appendectomy is the most common emergent surgery, and various techniques were used for the closure of appendicular stump and appendiceal artery.

Aim:

This study aimed to compare the clinical impacts of absorbable polymeric clips and traditional metallic clips.

Methods:

We reviewed the laparoscopic appendectomies performed from June 2020 to May 2021 in a medical center. We analyzed the characteristics and intraoperative and postoperative data of patients receiving absorbable or metallic clips during laparoscopic appendectomy.

Results:

A total of 120 patients were enrolled in this study. Fifty-nine patients received lapro-clips for the ligation of appendicular stump and artery (Group A), whereas 61 patients received titanium clips (Group B). The operative time for both groups was 63.6 ± 18.9 min and 65.5 ± 19.2 min, respectively (P = 0.586). There was no significant difference in postoperative complications (P = 0.958). The length of hospital stay for each group was 3.07 ± 1.14 days and 2.90 ± 1.18 days, respectively (P = 0.435).

Conclusion:

The application of absorbable polymetric clips is feasible and safe with the additional benefit of leaving no foreign body for the closure of appendicular stump and ligation of appendiceal artery for laparoscopic appendectomy.

Intrauterine devices (IUDs) are one of the most popular reversible contraception methods. However, if an event related to them is unanticipated, or if they are not located when missing, it can be dangerous. We present a case of chronic lower abdomen pain and recurrent urinary tract infection ongoing for 1.5 years. Despite the patient undergoing laparoscopic uterine myomectomy, her symptoms had not improved. The patient visited a genitourinary clinic for lower urinary tract symptoms and accepted cystoscopy and electrohydraulic lithotomy. Incidentally, a part of an IUD was found in the calculus. This case highlights the need for careful diagnosis and for locating missing IUDs to avoid serious complications.

Objective:

Wet cupping therapy (WCT) is one of the complementary and traditional therapies that are still must be scientifically interpreted. This study aimed to assess hemogram parameters that are subclinical inflammatory markers in patients with fibromyalgia syndrome (FMS) and observe how they were affected with WCT.

Methods:

The present study consisted of two groups; patient group included participants who were diagnosed with FMS and who received WCT and control group included healthy participants who received WCT within the concept of preventive medicine.

Results:

Neutrophil-to-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) values were higher in the patient group (P = 0.029 and P = 0.003, respectively). Considering that the participants had FMS, the optimal cutoff value for PLR was ≥1.62, sensitivity was 70%, specificity was 56%, positive predictive value was 61.7%, and negative predictive value was 65.3%. Receiver operating characteristic (ROC) curve revealed a significant sensitivity and specificity (ROC area = 0.664), (confidence interval [CI]: 0.530–0.781) (P < 0.023). The optimal cutoff value for PLR was ≥146, sensitivity was 60%, specificity was 83%, positive predictive value was 78%, and negative predictive value was 67%. ROC curve revealed a statistically significant sensitivity and specificity (ROC area = 0.726), (CI: 0.59–0.83) (P < 0.001). The optimal cutoff value for platelet was ≥284,000, sensitivity was 83%, specificity was 40%, positive predictive value was 58%, and negative predictive value was 70%. ROC curve revealed a significant sensitivity and specificity (ROC area = 0.65), (CI: 0.51–0.76) (P = 0.036).

Conclusion:

NLR, PLR, and thrombocyte count parameters can be useful in the process of diagnosing FMS. In addition, NLR, PLR, and MPV decreased in patients who received WCT.

Introduction: Using real-time graphics in health education is particularly relevant in technical skill development and knowledge acquisition in surgery, emergency medicine, and nursing.
Objective: To systematize the literature on using real-time graphics in health education.
Methods: A systematic review was conducted in the databases: PubMed, Scopus, Embase, Web of Science, Cochrane Library, CINAHL, and ERIC.
Results: The impact of real-time graphics use, including virtual reality (VR), in health education was examined, covering disciplines such as medicine, nursing, and other related professions. The findings of the selected studies for this review and existing literature suggest that implementing real-time graphics technologies in health education can significantly improve learning and the acquisition of clinical skills compared to traditional approaches.
Conclusions: Virtual reality was found to be particularly effective in training technical skills and surgical procedures and improving the quality of teaching in various disciplines. These findings support experiential learning theory and the idea that repeated practice and immediate feedback in a safe and controlled environment are essential for skill acquisition.
Callias-type operators associated to spectral triples
Authors: Schulz-Baldes Hermann , Stoiber Tom
Published: April 2023

Callias-type (or Dirac-Schrödinger) operators associated to abstract semifinite spectral triples are introduced and their indices are computed in terms of an associated index pairing derived from the spectral triple. The result is then interpreted as an index theorem for a non-commutative analogue of spectral flow. Both even and odd spectral triples are considered, and both commutative and non-commutative examples are given.

OBJECTIVES: The adverse health effects of individual-level social isolation (e.g., perceived loneliness) have been well documented in older adults. However, little is known about the impact of collective-level social isolation on health outcomes. We sought to examine the association of group-level segregation with cardiovascular health (CVH) in older adults.METHODS: From the prospective Korean Social Life, Health, and Aging Project database, we identified 528 community-dwelling older adults who were aged ≥60 years or were married to those aged ≥60 years. Participants who belonged to smaller social groups separate from the major social group were defined as group-level-segregated. The CVH score was calculated as the number of ideal non-dietary CVH metrics (0-6), as modified from the American Heart Association’s Life’s Simple 7. Using ordinal logistic regression models, we assessed cross-sectional and longitudinal associations between group-level segregation and CVH.RESULTS: Of the 528 participants (mean age, 71.7 years; 60.0% female), 108 (20.5%) were segregated at baseline. In the crosssectional analysis, group-level segregation was significantly associated with lower odds of having a higher CVH score at baseline after adjusting for socio-demographic factors and cognitive function (odds ratio [OR], 0.64; 95% confidence interval [CI], 0.43 to 0.95). Among 274 participants who completed an 8-year follow-up, group-level segregation at baseline was marginally associated with lower odds of having a higher CVH score at 8 years (OR, 0.49; 95% CI, 0.24 to 1.02).CONCLUSIONS: Group-level segregation was associated with worse CVH. These findings imply that the social network structure of a community may influence its members’ health status.

On December 14, 2020, southern South America experienced a total solar eclipse close to the solar noon. The path of totality, about 90 km wide, extended over the continental region from the Chilean west coast to the Argentine east coast, passing through the provinces of Neuquén, Río Negro and the extreme south of Buenos Aires. In order to study the effects on the atmosphere produced by the total eclipse, the Servicio Meteorológico Nacional Argentino (SMN) and Instituto de Investigaciones Científicas y Técnicas para la Defensa (CITEDEF) carried out a surface radiometric monitoring campaign in Valcheta (40.69°S; 66.15°W), Río Negro, Argentina. In this work, we explore the global surface solar irradiance on a horizontal plane (GHI) with the main objective of quantifying the changes in this parameter for cloudy and clear sky atmospheric conditions, combining ground-based measurements and modeling. A solar limb-darkening function was successfully implemented in the calculation of the irradiance at the top of the atmosphere (TOA) during the eclipse. We estimated a significant GHI attenuation of 41 % between the first (C1) and last (C4) contacts of eclipse compared to similar atmospheric conditions without the total eclipse, which represent a daily reduction of 12 %. In terms of irradiation, a reduction of 3360.1 KJ/m2 was calculated.
KRITIK HIERARKI KEBUTUHAN MASLOW BERDASARKAN PRINSIP CINTA KASIH DALAM PERJANJIAN BARU
Authors: Polly Welly Welliam , Notoprodjo Hartati Muljani , Hutauruk Kezia Tesalonika
Published: April 2023

Teori Hierarki Kebutuhan Maslow banyak dipakai di berbagai bidang karena teori ini secara intuitif tampak logis. Namun setelah dievaluasi dengan antropologi Alkitabiah dan prinsip kasih dalam Perjanjian Baru yang didapat dengan pendekatan teologi biblika, teori ini memiliki tiga kesalahan mendasar sehingga tidak seharusnya dipergunakan sebagai cara untuk manusia mengaktualisasi diri. Pertama, pengabaian Tuhan, Sang Pencipta dan Sumber Kasih Abadi yang sempurna sehingga tidak mengikut-sertakan kebutuhan pemahaman jati diri dan makna/tujuan eksistensi manusia untuk mencapai aktualisasi diri serta tidak mencari pemenuhan kasih dari Allah. Kedua, penempatan kebutuhan kasih bukan di kebutuhan primer bersama dengan kebutuhan fisik. Ketiga, pemisahan kebutuhan rasa berharga dan memiliki dimiliki dari kebutuhan kasih dan diletakkan lebih tinggi dari kebutuhan kasih sedangkan dua kebutuhan ini otomatis terpenuhi ketika kebutuhan kasih terpuaskan. Karena manusia terdiri dari roh dan tubuh, serta roh lebih penting dari tubuh, maka kasih dan kebutuhan fisik adalah kebutuhan primer yang bila dipuaskan akan memampukan manusia mencapai aktualisasi diri yang seharusnya tanpa perlu melalui jenjang kebutuhan rasa berharga dan kebutuhan memiliki-dimiliki.
Hidup Selibat Sebagai Karunia Tuhan: Studi Eksposisi 1 Korintus 7:7
Authors: Sibarani Yosua
Published: April 2023

Setiap orang memiliki panggilan unik dari Tuhan, termasuk panggilan hidup menikah atau tidak. Ada asumsi bahwa hidup selibat adalah hidup yang tidak lazim atau tidak normal. Di sisi lain, selibat dijadikan sebuah persyaratan mutlak bagi seorang imam tahbisan di dalam gereja Katolik. Alkitab menjunjung tinggi pernikahan, tetapi Alkitab juga mengajarkan tentang karunia hidup selibat (1 Kor. 7:7). Artikel ini bertujuan untuk menjelaskan hidup selibat sebagai karunia Tuhan berdasarkan studi eksposisi 1 Korintus 7:7 serta implikasi teologis bagi hidup orang percaya. Untuk itu, penulis menggunakan metode kualitatif dengan pendekatan studi literatur. Artikel ini memberikan kesimpulan bahwa hidup selibat adalah karunia Tuhan secara khusus bagi orang tertentu. Terakhir, implikasi hidup selibat sebagai karunia Tuhan adalah hidup selibat bukanlah kutuk atau aib, hidup selibat bukan soal lebih rohani (kudus) atau tidak, dan hidup selibat bukanlah persyaratan mutlak untuk menjadi pelayan Tuhan.
DEVELOPMENT AND VERİFİCATİON OF A MULTİBLOCK STRUCTURED GRİD SOLVER FOR 3D EULER/NAVİER-STOKES EQUATİONS
Authors: KIRAN Defne , ÇETE Ali Ruhsen
Published: April 2023

A multiblock structured grid solver for 3D Euler/Navier-Stokes equations is developed in this study. The solver employs the finite difference method together with the lower-upper factored scheme to provide fast solutions, while the use of multiblock structured grids allows the algorithm to be applied to complex geometries.
The developed solver is then tested on a "body-only" axisymmetric model with a single-engine fighter aft-end which was previously investigated experimentally. The numerical results of the pressure distributions on the model's body obtained by the solver are compared to the experimental results. The numerical and experimental results were found to be in good agreement, indicating that the solver can sufficiently solve the flow equations, and represent the physical properties of the flow.
