Published: December 2024

In fish challenge tests, there is no standardization in the concentration and analysis period of parameters. This study investigates the immunomodulatory and cytotoxic effects of A. hydrophila dose and postimmunostimulation periods on Nile tilapia. Four level of bacterial doses (½, ¼, ⅛, and 0 LD50) were administered, and immune parameters, hematological data, and erythrocyte abnormalities were analyzed at 3, 7, 10, and 14 days post-infection (dpi). The highest respiratory burst, total globulins, and lysozyme activity were detected at 7 dpi. Considering the bacteria doses, the lysozyme activity was higher in the ⅛ LD50 and ¼ LD50 of A. hydrophila. Erythrocytes, hematocrit, hemoglobin, leukocytes, lymphocytes, neutrophils, and monocytes counts remained unchanged. Ten days post-injection, the control group exhibited reduced abnormalities, showing a notable distinction from the ⅛ LD50 and ¼ LD50 treatments, particularly in hooked and notched nuclei abnormalities. Mortality rates were higher in infected groups, peaking at different times with the highest in ½ LD50. For evaluating Nile tilapia immunity post A. hydrophila infection, it is recommended ¼ LD50 dose and blood collection at 7 and 10 dpi for immunological parameters and abnormalities in Nile tilapia erythrocytes, respectively.

Published: December 2024

The aim of this study was to identify and understand the different characteristics of toddlers in the context of factors that contribute to nutritional stunting. By using the clustering method, this study aims to group toddlers into several groups based on the similarity of their characteristics, so that more targeted interventions can be designed in dealing with stunting problems. Through this approach, it is hoped that significant patterns and risk factors can be found that distinguish stunted toddlers from toddlers who grow normally, and provide insights that can be used by policy makers and health practitioners to improve the quality of life of children. The method used in this study involves the application of two clustering techniques, namely K-Means and K-Medoids to Group sample data of 116 toddlers. The clustering process is carried out by measuring the distance between the toddler data and the centroid or medoid to determine which group is most suitable. The Data were analyzed to find patterns identifying unique characteristics of each cluster, reflecting differences in nutritional stunting-related risk factors.This process helps in differentiating groups of toddlers who are prone to stunting from those who are not, so that the analysis can be focused on the groups most in need of intervention. The results of clustering analysis showed that as many as 48 toddlers entered the C1 cluster, while the other 68 toddlers entered the C2 cluster. Each cluster describes two groups of toddlers with different characteristics in the context of nutritional stunting risk factors. The findings provide deep insight into the significant differences between the two groups, allowing researchers to identify specific patterns and risk factors. This information is then used to design more specific and effective interventions in addressing nutritional stunting in toddlers, taking into account the unique characteristics of each cluster that has been identified.

Economic and Fiscal Risks of Corporate Taxation Option for Partnerships in Germany
Authors: Buschhaus Matthias
Published: December 2024

The aim of this paper is the examination of the economic and fiscal risks of the taxation option available as of January 1, 2022 for partnerships in Germany to be taxed as corporations (hereinafter referred to as the "option model") in accordance with Section 1a of the German Corporation Tax Act ("KStG").
With regard to the economic risks, particular attention was paid to the economic risks for the exercising partnership, which arise both at the time the option is exercised and during the subsequent taxation process. As a result, the retrospective taxation risks and the lack of planning certainty regarding a potential reversion to the tried and tested taxation regime were recognised as the main risks in this regard.
Regarding the fiscal risks, an assessment was made of the German government's forecast of additional and reduced tax revenue if the option model is implemented in law. This was supplemented by a classification of tax revenue with regard to the figures published by the German Federal Statistical Office for 2022. The result with regard to the fiscal risks was that there is no significant impact on the state budget in relation to the option model, meaning that no negative consequences have been recognised to date.

This work presents a unique and straightforward method to synthesise hafnium oxide (HfO2) and hafnium carbide (HfC) nanoparticles (NPs) and to fabricate hafnium nanostructures (NSs) on a Hf surface. Ultrafast picosecond laser ablation of the Hf metal target was performed in three different liquid media, namely, deionised water (DW), toluene, and anisole, to fabricate HfO2 and HfC NPs along with Hf NSs. Spherical HfO2 NPs and nanofibres were formed when Hf was ablated in DW. Hf ablated in toluene and anisole demonstrated the formation of core–shell NPs of HfC with a graphitic shell. All NPs exhibited novel optical reflectance properties. Reflectance measurements revealed that the fabricated NPs had a very high and broad optical absorption throughout the UV–vis–NIR range. The NPs synthesised in toluene exhibited the best absorption. The successful fabrication of Hf NSs with the formation of laser-induced periodic surface structures (LIPSS) with low spatial frequency (LSFL) and high spatial frequency (HSFL) orthogonal to each other was also demonstrated. The LSFL and HSFL both exhibited quasi-periodicity. This work presents a simple way to fabricate HfO2 and HfC NPs and provides insight into their morphological and optical characteristics paving way for their applications in future.

The bezoar is a conglomerate of indigestible or partially digestible foreign material that stagnates in the digestive tract. Cases of primary intestinal trichobezoar, without associated gastric trichobezoar, are rare. Trichobezoar occurs most frequently in patients with mental disorders. We present the case of a patient aged 12 years and 5 months, who was referred to our hospital with the suspicion of intestinal obstruction, the clinical symptomatology consisting of uncontrollable vomiting, cramping abdominal pain and the absence of intestinal transit. Imaging investigations were inconclusive as to the cause of the bowel obstruction. Surgery was performed for mechanical intestinal obstruction and during the exploratory laparotomy an intraluminal formation was revealed in the ileum which after enterotomy was identified as a trichobezoar and other formations in the colon which were manually manipulated towards the distal colon and later evacuated manually by digital rectal palpation. Postoperative pediatric psychiatric evaluation revealed symptoms suggestive of Asperger Syndrome. Our paper, explores the association between tricophagy and pervasive developmental disorders. Although many cases of autistic children ingesting inedible items are described in the literature, there are very rare situations in which pica causes obstruction of the small intestine, requiring surgical intervention.

Bd. 1: Voraussetzungen des 20. Jahrhunderts bis 1990
Authors: Düring Michael
Published: December 2024

Russische Satire nach dem Zerfall der Sowjetunion. Voraussetzungen des 20. Jahrhunderts bis 1990 – so lautet der Titel des hier vorliegenden ersten Bandes eines auf drei Bände
angelegten Projekts. Nach einer Einführung und einem Kapitel, das Fragen nach Gattung und Modus gewidmet ist, fokussiert dieser Band zentrale Kategorien der Satire: Welche Mittel
gibt es und können im sowjetischen 20. Jahrhundert angewendet werden, welche Opfer rücken in den Blickpunkt, welche Rollen können Verfasser von Satiren einnehmen und wie wird in
literarischen Werken selbstreflexiv über Funktion und Wirkung von Satire nachgedacht? Beantwortet werden diese Fragen durch den Rückgriff auf ein breites Spektrum satirischer Werke,
die bewusst die Gattungsgrenzen überspringen und, auch auf Traditionslinien des 18. und 19. Jahrhunderts Bezug nehmend, kontextualisiert werden. So wird erkennbar, auf welche
Verfahren sich die Satire der Perestrojka-Jahre stützen kann und wie sie sich verändert; es wird aber zugleich antizipiert, welche Horizonte sich für die russischsprachige Satire
der El’cin-Ära (Band 2) und der Putin-Herrschaft (Band 3) eröffneten.

Published: December 2024

E-commerce in Indonesia has grown rapidly, becoming essential as more people prefer online shopping. A Populix (2023) survey indicates Indonesians tend to make unplanned purchases. Impulse buying is driven by external factors like sales promotions and internal factors like hedonic shopping motivation, with positive emotions mediating this effect. This study analyzes how sales promotions and hedonic shopping motivation influence impulse buying in e-commerce, with positive emotion serving as an intervening variable. The method used in this research is quantitative with a questionnaire carried out systematically following the research objectives. The population in this study was Indonesian people who had used e-commerce for online shopping, with 120 respondents. This study uses a 5-point Likert scale and PLS-based SEM for analysis. Results indicate that (1) sales promotion and (2) hedonic shopping motivation both positively affect impulse buying; (3) sales promotion and (4) hedonic shopping motivation positively influence positive emotions; (5) positive emotions, in turn, increase impulse buying; (6) positive emotion thoroughly explains the link between sales promotion and impulse buying; (7) it partially explains the effect of hedonic motivation on impulse buying. Recommendations suggest e-commerce should consider psychological factors and consumer motivation in marketing strategies, and future research could explore factors like celebrity endorsers, shopping lifestyle, and advertising.

This study examines the role of the ATLAS application in moderating the influence of due professional care and accountability on audit risk assessment in public accounting firms (KAP) in Bali Province. This study uses a quantitative approach with the purposive sampling method to determine respondents, and data analysis is carried out using Moderated Regression Analysis (MRA). This study uses the COSO ERM theory to help understand and explain the research results related to risk management in the audit process. The study results show that due professional care has a positive and significant effect on audit risk assessment in Bali Province, which indicates that auditors who perform their duties with professional prudence tend to produce more accurate risk assessments. On the other hand, accountability had a positive but insignificant effect on audit risk assessment, suggesting that although there is a positive relationship, the influence is not strong enough to be considered statistically significant. The role of ATLAS cannot moderate the influence of due professional care or accountability on audit risk assessment, which indicates that ATLAS, although designed to support the audit process, has not been effective in strengthening the relationship. This study provides insights into the importance of due professional care in audit risk assessment and optimising the use of ATLAS in implementing audits.

This study aims to explore the role of debt policy, dividend policy and investment decisions on Firm Value, especially in telecommunications companies, during the period 2019 to 2022. The sampling method used was purposive sampling, and data analysis was carried out using SPSS software version 20. From the findings, the debt policy -DER (X1) affects firm value. The study found that the DER regression coefficient is -41.649, with a t-value of -2.085 and a significance of 0.048 (<0.05), indicating that debt policy significantly affects firm value (H1 accepted). For DPR, the regression coefficient is 68.923, but the t-value is 0.154 with a significance of 0.411 (>0.05), meaning dividend policy does not significantly impact firm value (H2 rejected). This aligns with the bird-in-hand theory, suggesting current dividend payments are preferred over future capital gains. Meanwhile, PER (X3) has a positive regression coefficient of 0.539, a t-value of 0.645, and a significance of 0.025 (<0.05), confirming a positive and significant impact on firm value (H3 accepted). These findings offer insights into the dynamics of debt, dividend, and investment decisions within the telecommunications sector.

Authors: Jiono Jiono - , Aristyanto Erwan
Published: December 2024

Tourism development is the key to the success of Mojokerto Regency as a developing city, which is able to transform Mojokerto Regency as a tourism destination as well as a tourist destination. The development strategy in Mojokerto district which was developed based on tourism destinations is closely related to the concept of defense economics so that it places the community as the main actor. The problem that then arises is that tourism development has implications for the welfare of the people of Mojokerto Regency.
               The trend of increasing local original income over the last five years has enabled the potential of the Mojokerto Regency tourism sector as an alternative for alleviating poverty as well as increasing community welfare. The research aims to analyze new tourism objects in Mojokerto Regency as well as increasing new economic sectors through tourism activities in each sub-district in the Mojokerto City area. The research used qualitative methods through interviews and observations at Mojokerto Regency Government levels as a tourist destination as well as group discussions with residents. The research results show that the tourism sector contributes to the welfare of Mojokerto Regency, especially equal distribution of income as well as regional cash income, however the facilities and infrastructure as well as tourism infrastructure still need to continue to be improved so as to attract more visitors to Mojokerto Regency.

Extreme coronal-line emitters (ECLEs) are objects showing transient high-ionization lines in the centers of galaxies. They have been attributed to echoes of high-energy flares of ionizing radiation, such as those produced by tidal disruption events (TDEs), but have only recently been observed within hundreds of days after an optical transient was detected. AT 2022upj is a nuclear UV–optical flare at z = 0.054, with spectra showing [Fe x] λ6375 and [Fe xiv]​​​​​ λ5303 during the optical peak, the earliest presence of extreme coronal lines during an ongoing transient. AT 2022upj is also the second ever ECLE (and the first with a concurrent flare) to show broad He ii
λ4686 emission, a key signature of optical/UV TDEs. We also detect X-ray emission during the optical transient phase, which may be related to the source of ionizing photons for the extreme coronal lines. Finally, we analyze the spectroscopic evolution of each emission line and find that [Fe x] and [Fe xiv] weaken within 400 days of the optical peak, while [Fe vii] λ5720, [Fe vii] λ6087, and [O iii] λλ4959,5007 emerge over the same period. The velocities of the iron lines indicate circumnuclear gas within 0.1 pc of the central supermassive black hole (SMBH), while a dust echo inferred from NEOWISE data indicates that circumnuclear dust lies a minimum of 0.4 pc away, providing evidence of stratified material around an SMBH. AT 2022upj is thus the first confirmed ECLE–TDE with clear signatures of both classes and with spectroscopic evolution on a ∼year-long timescale. This event helps unveil the impacts of highly energetic flares such as TDEs on the complex environments around SMBHs.

Models predict that the well-studied mass–radius relation of white dwarf stars depends on the temperature of the star, with hotter white dwarfs having larger masses at a given radius than cooler stars. In this paper, we use a catalog of 26,041 DA white dwarfs observed in Sloan Digital Sky Survey Data Releases 1–19. We measure the radial velocity, effective temperature, surface gravity, and radius for each object. By binning this catalog in radius or surface gravity, we average out the random motion component of the radial velocities for nearby white dwarfs to isolate the gravitational redshifts for these objects and use them to directly measure the mass–radius relation. For gravitational redshifts measured from binning in either radius or surface gravity, we find strong evidence for a temperature-dependent mass–radius relation, with warmer white dwarfs consistently having greater gravitational redshifts than cool objects at a fixed radius or surface gravity. For warm white dwarfs, we find that their mean radius is larger and mean surface gravity is smaller than those of cool white dwarfs at 5.2σ and 6.0σ significance, respectively. Selecting white dwarfs with similar radii or surface gravities, the significance of the difference in mean gravitational redshifts between the warm and cool samples is >6.1σ and >3.6σ for measurements binned in radius and surface gravity, respectively, in the direction predicted by theory. This is an improvement over previous implicit detections, and our technique can be expanded to precisely test the white dwarf mass–radius relation with future surveys.
The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

Published: December 2024

The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 109 particle N-body simulations, illustrating the response of the stellar disk of the MW to the close approach of the LMC and the merger of Sgr into the MW. The suite is intended to provide a resource for others to study the complex interactions between the MW and its satellites independently and together, in comparison to an isolated disk control simulation. The high temporal and mass resolution allows for a quantitative Fourier decomposition of the stellar kinematics, disentangling the individual influence of each satellite on the MW. In our preliminary analysis, we find that the influences from the LMC and Sgr on the disk of the MW appear distinct, additive, and separable within our tailored simulations. Notably, the corrugations induced by Sgr reproduce the large radial velocity wave seen in the data. Overall, our findings emphasise the need to include both satellites when modeling the present-day state of the MW structure and kinematics.

Through a detailed timing analysis of Fermi-LAT data, the rotational behavior of the γ-ray pulsar PSR J1522−5735 was tracked from 2008 August (MJD 54692) to 2024 January (MJD 60320). During this 15.4 yr period, two overrecovery glitches and four antiglitches were identified, marking a rare occurrence in rotation-powered pulsars (RPPs). The magnitudes of these (net) spin-down glitches were determined to be ∣Δν
g/ν∣ ∼ 10−8, well above the estimated detectability limit. For the two overrecovery glitches, the respective recovery fractions Q are 2.1(7) and 1.4(2). Further analysis showed no substantial variations in either the flux or pulse profile shape in any of these events, suggesting that small (net) spin-down glitches, unlike large events observed in magnetars and magnetar-like RPPs, may occur without leaving an impact on the magnetosphere. Within the framework of the vortex creep and vortex bending models, antiglitches and overrecoveries indicate the recoupling of vortex lines that moved inward as a result of a crustquake; meanwhile, the apparent fluctuations in the spin-down rate after the glitches occur as a result of the coupling of the oscillations of bent vortex lines to the magnetosphere.
