BAHAYA DAN RISIKO BAHAN KIMIA PADA PEKERJAAN LAUNDRY PADA RUMAH SAKIT ABC DI KOTA BALIKPAPAN
Authors: Rusba Komeyni , Wolo Daniel 
Published: April 2024

Fasilitas pelayanan kesehatan khususnya rumah sakit di mana terdapat instansi non medik yang berkaitan dengan bahaya pada instalasi laundry diantaranya bahaya infeksius, bahaya kimia, fisika, biologi dan lain-lain, yang berisiko lebih rentan terhadap kesehatan para pekerja ataupun masyarakat yang berada diarea rumah sakit tersebut. Dalam proses pekerjaan di laundry ada berbagai macam faktor bahaya salah satunya adalah bahaya bahan kimia yang diakibatkan oleh deterjen untuk pencucian linen infeksius dan non infeksius. Kurangnya pemahaman tentang potensi bahaya pada proses pekerjaan di instalasi laundry akan menimbulkan risiko penyakit yang berdampak pada kesehatan karyawan laundry, jika tidak adanya pengendalian dalam penggunaan bahan kimia tersebut. Pengaruh bahan kimia tersebut juga dapat menimbulkan kebakaran, ledakan, keracunan,dan iritasi pada permukaan tubuh manusia serta risiko-risiko lain yang membahayakan. Oleh karena itu perlu adanya pemahaman dan kesadaran yang lebih pada pekerja laundry tersebut mengenai dampak dari pemakaian bahan kimia laundry tersebut guna menimalisir risiko penyakit akibat dari bahan kimia tersebut.

Joint contributions of preview and task instructions on visual search strategy selection

Published: April 2024

AbstractPeople tend to employ suboptimal attention control strategies during visual search. Here we question why people are suboptimal, specifically investigating how knowledge of the optimal strategies and the time available to apply such strategies affect strategy use. We used the Adaptive Choice Visual Search (ACVS), a task designed to assess attentional control optimality. We used explicit strategy instructions to manipulate explicit strategy knowledge, and we used display previews to manipulate time to apply the strategies. In the first two experiments, the strategy instructions increased optimality. However, the preview manipulation did not significantly boost optimality for participants who did not receive strategy instruction. Finally, in Experiments 3A and 3B, we jointly manipulated preview and instruction with a larger sample size. Preview and instruction both produced significant main effects; furthermore, they interacted significantly, such that the beneficial effect of instructions emerged with greater preview time. Taken together, these results have important implications for understanding the strategic use of attentional control. Individuals with explicit knowledge of the optimal strategy are more likely to exploit relevant information in their visual environment, but only to the extent that they have the time to do so.
THE LOCUS OF THE FOREST IN THE WORKS OF A.S. PUSHKIN
Authors: Юхнова И.С. 
Published: April 2024

В статье рассматривается, как в творчестве Пушкина представлен локус леса, прослежено, как в семантике леса взаимодействует фольклорное и индивидуально-авторское, показано приращение новых смыслов в пушкинской символике леса. Особый акцент сделан на особенностях пушкинского изображения леса. Отмечено, что в ранней лирике лес включается в описание как некая отдаленность, к которой устремляется взгляд, является границей, оформляющей пространство, обрамляющей его, так локализуется место действия. Начиная с лирики, созданной в Михайловском, лес получает конкретные черты, фиксируются не только колористические детали, но и звуковые. В прозе лес является значимой приметой русского ландшафта, он связан с узловыми моментами жизни героев, изображается не как сплошная масса деревьев, а как сложноорганизованное пространство. Герои вступают с лесом в своеобразный диалог. Лес становится многозначным образом-символом.
The article explores the representation of the forest locus in Pushkin’s works, the interaction between folklore and individual-authorial in the semantics of the forest, show the shows the addition of new meanings in Pushkin’s symbolism of the forest. The researcher pays special attention to on the features of depiction of the forest by Pushkin. The article points out that in early poetry forest is included into a description as a kind of remoteness, to which the eye is drawn; it is a border, defining and framing a space, thus localising the place of action. Beginning from the poetry, written in Mikhailovskoye, the forest acquires particular features, being described with not only coloristic, but also sonic details. In prose a forest is a significant feature of a Russian landscape, which is connected with key life moments of heores. It is depicted not as a solid mass of trees, but as a complex space. Heroes engage in a sort of a dialogue; thus a forest becomes a polysemous image-symbol.
Dynamical Structures under Nonrestricted Hierarchical Planetary Systems with Different Mass Ratios
Authors: Huang Xiumin , Lei Hanlun 
Published: April 2024

Abstract
Secular dynamics have been extensively studied in both the inner and outer restricted hierarchical three-body systems. In the inner restricted problem, the quadrupole-order resonance (i.e., the well-known Kozai resonance) causes large coupled oscillations of eccentricity and inclination when the maximum inclination is higher than 39.2°, and the octupole-order resonance leads to the behavior of orbital flips. In the outer restricted problem, the behavior of orbital flips is due to the quadrupole-order resonance. Secular dynamics under the inner and outer restricted systems are distinctly different. The mass ratio of inner and outer bodies could change the ratio of circular orbital angular momenta β, which significantly influences dynamical structures of the system. But this influence is still unclear. In this paper, we focus on nonrestricted hierarchical planetary systems where β > 1 and investigate the secular dynamics by changing mass ratios. Dynamical structures are systematically explored from four aspects: periodic orbits, secular resonances, orbital flips, and chaos detection. We find that (a) it tends to lead to more bifurcations in the host family of prograde periodic orbits associated with Kozai resonance with smaller β; (b) with the decrease of β, fewer orbits inside the octupole-order resonance can realize flip; (c) for given initial conditions, the forbidden region appears in the retrograde region and becomes larger as β decreases, meaning that the mutual inclination cannot reach a very high value if β is small; and (d) chaotic orbits are distributed in the low-eccentricity, high-inclination region when β > 1.
The Impact of Cometary “Impacts” on the Chemistry, Climate, and Spectra of Hot Jupiter Atmospheres
Authors: Sainsbury-Martinez F. , Walsh C. 
Published: April 2024

Abstract
Impacts from icy and rocky bodies have helped shape the composition of Solar System objects; for example, the Earth–Moon system, or the recent impact of comet Shoemaker–Levy 9 with Jupiter. It is likely that such impacts also shape the composition of exoplanetary systems. Here, we investigate how cometary impacts might affect the atmospheric composition/chemistry of hot Jupiters, which are prime targets for characterization. We introduce a parameterized cometary impact model that includes thermal ablation and pressure driven breakup, which we couple with the 1D “radiative-convective” atmospheric model ATMO, including disequilibrium chemistry. We use this model to investigate a wide range of impactor masses and compositions, including those based on observations of Solar System comets, and interstellar ices (with JWST). We find that even a small impactor (R = 2.5 km) can lead to significant short-term changes in the atmospheric chemistry, including a factor >10 enhancement in H2O, CO, and CO2 abundances, as well as atmospheric opacity more generally, and the near-complete removal of observable hydrocarbons, such as CH4, from the upper atmosphere. These effects scale with the change in atmospheric C/O ratio and metallicity. Potentially observable changes are possible for a body that has undergone significant/continuous bombardment, such that the global atmospheric chemistry has been impacted. Our works reveals that cometary impacts can significantly alter or pollute the atmospheric composition/chemistry of hot Jupiters. These changes have the potential to mute/break the proposed link between atmospheric C/O ratio and planet formation location relative to key snowlines in the natal protoplanetary disk.

Abstract
We present deep XMM-Newton, Karl G. Jansky Very Large Array, and upgraded Giant Metrewave Radio Telescope observations of Abell 746, a cluster that hosts a plethora of diffuse emission sources that provide evidence for the acceleration of relativistic particles. Our new XMM-Newton images reveal a complex morphology of the thermal gas with several substructures. We observe an asymmetric temperature distribution across the cluster: the southern regions exhibit higher temperatures, reaching ∼9 keV, while the northern regions have lower temperatures (≤4 keV), likely due to a complex merger. We find evidence of three surface brightness edges and one candidate edge, of which three are merger-driven shock fronts. Combining our new data with published LOw-Frequency ARray observations has unveiled the nature of diffuse sources in this system. The bright NW relic shows thin filaments and a high degree of polarization with aligned magnetic field vectors. We detect a density jump, aligned with the fainter relic to the north. To the south, we detect high-temperature regions, consistent with the shock-heated regions and a density jump coincident with the northern tip of the southern radio structure. Its integrated spectrum shows a high-frequency steepening. Lastly, we find that the cluster hosts large-scale radio halo emission. A comparison of the thermal and nonthermal emission reveals an anticorrelation between the bright radio and X-ray features at the center. Our findings suggest that Abell 746 is a complex system that involves multiple mergers.
Bright Supernova Precursors by Outbursts from Massive Stars with Compact Object Companions
Authors: Tsuna Daichi , Matsumoto Tatsuya , Wu Samantha Chloe , Fuller Jim 
Published: April 2024

Abstract
A fraction of core-collapse supernovae (SNe) with signs of interaction with a dense circumstellar matter are preceded by bright precursor emission. While the precursors are likely caused by a mass ejection before core collapse, their mechanism to power energetic bursts—sometimes reaching 1048–1049 erg, which is larger than the binding energies of red supergiant envelopes—is still under debate. Remarkably, such a huge energy deposition should result in an almost complete envelope ejection and hence a strong sign of interaction, but the observed SNe with precursors show in fact typical properties among the interacting SNe. More generally, the observed luminosity of 1040−1042 erg s−1 is shown to be challenging for a single SN progenitor. To resolve these tensions, we propose a scenario where the progenitor is in a binary system with a compact object (CO) and an outburst from the star leads to a super-Eddington accretion onto the CO. We show that for sufficiently short separations outbursts with moderate initial kinetic energies of 1046–1047 erg can be energized by the accreting CO so that their radiative output can be consistent with the observed precursors. We discuss the implications of our model in relation to CO binaries detectable with Gaia and gravitational-wave detectors.

Abstract
We performed experiments of implantation of energetic sulfur ions (105 keV) into 2:1 water:propane ices at 80 K and analyzed the resulting refractory organic matter with ultrahigh-resolution mass spectrometry. Our goal was to characterize the organic matter processed in the surface conditions of Europa, where it would receive a heavy flux of energetic particles, including sulfur ions, and determine whether organosulfurs could be formed in these conditions, using the simplest alkane that can exist in solid form on Europa’s surface. We find that the produced organic matter contains a large variety of both aliphatic and aromatic compounds (several thousand unique formulae), including polycyclic aromatic hydrocarbons (PAHs), with masses up to 900 amu. A large number of aromatic hydrocarbons is found along with oxygenated, mostly aliphatic, compounds. Organosulfurs are found in both CHS and CHOS form, demonstrating they can be formed from any organic compound through sulfur implantation. These organosulfurs’ properties (aromaticity, mass) appear similar to the rest of the organic matter, albeit their low quantity does not allow for a thorough comparison. Our results have implications for the type of refractory organic matter that could be observed by the JUICE and Europa Clipper space missions and how the surface of Europa could generate complex organics, including PAHs and organosulfurs, that could then enrich the subsurface ocean. In particular, they indicate that a large diversity of organic matter, including organosulfurs, can be formed from simple precursors in a geologically short time frame under the ion flux that reaches Europa.

Le peuple des élites. Représentations élitaires et ordre moral à Madagascar
Authors: Wachsberger Jean-Michel 
Published: April 2024

Bien des travaux de recherche en sciences sociales ont insisté sur ­­l’importance des idées, croyances et représentations des groupes sociaux dirigeants pour la légitimation des comportements et ­­l’orientation des politiques publiques. Cependant, bien peu ­­d’entre eux ont développé ces analyses dans le cadre de sociétés africaines. Cet article innove sur ce point en procédant à une exploration des représentations élitaires à propos du peuple malgache à partir ­­d’une enquête originale menée auprès de 1 000 membres des plus hautes positions de pouvoir de la société de la Grande Île. Mobilisant les méthodes usuelles de ­­l’analyse textuelle mais aussi celles de la modélisation économétrique, ce travail fait apparaître que, bien que marquées par des sensibilités différentes, les représentations élitaires sont très homogènes. Les avis exprimés témoignent de la distance qui sépare ces élites ­­d’un peuple ­­qu’elles regardent de haut, avec bienveillance, inquiétude et/ou mépris, tout en marquant souvent une forme ­­d’incompréhension. Les différents registres employés constituent presque tous une façon de naturaliser la pauvreté et, par conséquent, de légitimer la position économique et sociale des personnes enquêtées. Leur peu de sens des responsabilités ­­vis-­­à-vis du sort du peuple et leur faible sentiment ­­d’interdépendance sociale limitent ainsi leur soutien à – et leur engagement dans – des politiques ­­pro-­­pauvres.
