Published: May 2024

Global warming is a symptom of an increase in the average temperature of the earth's surface. Global warming is caused by the large concentration of greenhouse gases in the atmosphere. One of the biggest greenhouse gases contributing to global warming is carbon dioxide (CO2). Forest vegetation can absorb about 50% of total emissions through a sequestration process stored in biomass in all parts of the plant. The study aimed to determine the potential of biomass, carbon stocks, carbon sequestration, oxygen production, and the CO2Â absorption value of environmental services in three types of ecosystems in Buton Regency, Southeast Sulawesi Province. Research sampling was conducted using purposive sampling techniques and roaming methods. Calculation of biomass potential, carbon stock, carbon sequestration, oxygen production, and environmental service value of CO2Â uptake using anÂ allometric formulaÂ The results of research on the biomass potential of mangrove forests, lambusango forests, and pine forests were respectively, 16,108.27 tons/ha, 84,693.72 tons/ha, and 14,273.98 tons/ha. The potential carbon stock is 8,054.13 tons/ha, 42,346.86 tons/ha, and 7,136.99 tons/ha. The carbon absorption potential is 29,558.67 tons/ha, 155,412.98 tons/ha, and 26,192.75 tons/ha. The potential oxygen production is 21,504.54 tons/ha, 113,066.12 tons/ha, and 19,055.76 tons/ha, while the value of environmental services CO2Â absorption is 2,221,038,614.63 Rp/ha, 11,677,731,637.57 Rp/ha, and 1,968,123,759 Rp/ha.

Published: May 2024

The production of Dendrobium striaenopsis orchid cultivation in Indonesia has many obstacles including limited seed provision, low seed quality and cultivation techniques that have not been done well, while orchid enthusiasts always increase every year. Propagation of orchid plants by conventional means requires a long time to obtain a large number of plant saplings, therefore alternative cultivation using tissue culture techniques is needed. In vitro tissue culture techniques are widely used as a fast and efficient way to produce D. striaenopsis orchid plants, but not infrequently there are factors that affect the production of orchids, one of which is bottle size. The purpose of this study is to determine the effect of the effectiveness of bottle size variations on the growth of D. striaenopsis plantlets after comparing the difference in bottle volume and knowing the optimum size of bottles used for D. striaenopsis plantlet growth. The study was conducted from May to August 2023 in the Laboratory CV. Candi Orchid, Semarang City. The method used was the observation and experimental method after which it was continued with the One Way Anova test and further test T. In this study using Vacin and Went medium with a size of 60 ml by providing treatment variations in bottle sizes of 250 ml, 500 ml and 750 ml with 4 repeats. The result of this study is that a 750 ml bottle used in the tissue culture technique of D. striaenopsis Orchid is effective in use even though the growth of plantlets does not occur a significant difference, this is due to environmental factors, namely light intensity and duration of irradiation

Published: May 2024

Browning of explants is a common problem in Kepel (Stelechocarpus burahol (Blume) Hook.f. & Thomson) in vitro culture, resulting in low explant in vitro regeneration of Kepel. Using nodal explant, the effect of explant immersion in ascorbic acid, the addition of ascorbic acid to the media, and dark and light incubation conditions were investigated. The browning prevention method was selected based on the delayed browning appearance time, the lowest broning intensity, and the highest percentage of callus. This present study used a completely randomized design with treatment variations: immersion explant in ascorbic acid 100 mg/L, addition of ascorbic acid 100 and 200 mg/L to the media, addition of ascorbic acid 100 and 200 mg/L and activated charcoal 1 g/L to the media, and incubation in dark and light conditions for 28 days. The results showed that the combination of the addition of ascorbic acid 200 mg/L to MS media and incubation in dark conditions were effective browning prevention methods in inhibiting browning appearance time (5 DAP), significantly reducing browning intensity (0.3), and increasing callus growth (100%) of kepel node explants during 28 days of culture. The results of this study are useful in establishing protocols for in vitro culture of Kepel plants, especially at the initiation stage, and can be expected to support the successful conservation of Kepel plants through in vitro propagation.

Published: May 2024

This research aims to conduct a comparative study analyzing the influence of additives on the physical and mechanical properties of concrete based on the results of previous research. Three relevant previous studies were used as a reference in analyzing the effect of additives on compressive strength, split tensile strength, modulus of elasticity and compressive strength of concrete. In Agus Setya Budi’s research, the use of fly ash with a content of 15% resulted in an increase in the compressive strength of concrete, while the use of fly ash levels of 30% and 40% resulted in a decrease in the compressive strength of the concrete. Samun Haris’ research shows that using silica fume powder at a level of 5% produces higher compressive strength results compared to a level of 15%. Meanwhile, Muhhamad Sadat’s research indicates that the use of slag as a substitute for fine aggregate increases the compressive strength of concrete along with increasing levels of slag substitution. Based on the analysis of the research results, it can be concluded that the use of additives in concrete has a significant influence on the physical and mechanical properties of concrete. However, the effect of added additives depends on the type and level of additives used. Therefore, it is necessary to pay attention to the selection of the right additives to achieve the desired concrete characteristics.
Construction of a Chinese traditional instrumental music dataset: A validated set of naturalistic affective music excerpts

Published: May 2024

AbstractMusic is omnipresent among human cultures and moves us both physically and emotionally. The perception of emotions in music is influenced by both psychophysical and cultural factors. Chinese traditional instrumental music differs significantly from Western music in cultural origin and music elements. However, previous studies on music emotion perception are based almost exclusively on Western music. Therefore, the construction of a dataset of Chinese traditional instrumental music is important for exploring the perception of music emotions in the context of Chinese culture. The present dataset included 273 10-second naturalistic music excerpts. We provided rating data for each excerpt on ten variables: familiarity, dimensional emotions (valence and arousal), and discrete emotions (anger, gentleness, happiness, peacefulness, sadness, solemnness, and transcendence). The excerpts were rated by a total of 168 participants on a seven-point Likert scale for the ten variables. Three labels for the excerpts were obtained: familiarity, discrete emotion, and cluster. Our dataset demonstrates good reliability, and we believe it could contribute to cross-cultural studies on emotional responses to music.

Abstract
This work analyzes the present-day mass function (PDMF) of 93 star clusters utilizing Gaia Data Release 3 data, with membership determined by the StarGo machine-learning algorithm. The impact of unresolved binary systems on mass estimation is rigorously assessed, adopting three mass ratio profiles for correction. The PDMF is characterized by the power-law index, α, derived through a robust maximum likelihood method that avoids biases associated with data binning. The value of α for stars between the completeness limited mass of Gaia (with a mean 0.3 M
⊙ for our cluster samples) and 2 M
⊙ exhibits stability for clusters younger than 200 Myr, decreasing for older clusters, particularly when considering stars within the half-mass radius. The PDMF of these star clusters is consistent with a dynamically evolved Kroupa initial mass function via the loss of low-mass stars. Cluster morphology shows a correlation with α, as α values exhibit a decreasing trend from filamentary to tidal-tail clusters, mirroring the sequence of increasing cluster age. The dependence of α on the total cluster mass is weak, with a subtle increase for higher-mass clusters, especially outside the half-mass radius. We do not observe a correlation between α and the mean metallicity of the clusters. Younger clusters have lower metallicity compared to their older counterparts, which indicates that the older clusters might have migrated to the solar neighborhood from the inner disk. A comparison with numerical models incorporating a black hole population suggests the need for observations of distant, older, massive open clusters to determine whether or not they contain black holes.

Abstract
We study the size and structure of globular cluster (GC) systems of 118 early-type galaxies from the NGVS, MATLAS, and ACSVCS surveys. Fitting Sérsic profiles, we investigate the relationship between effective radii of GC systems (R

e,gc) and galaxy properties. GC systems are 2–4 times more extended than host galaxies across the entire stellar mass range of our sample (108.3

color (Δgi): GCs with similar colors to their hosts have a “red” Δgi, and those significantly bluer GCs have a “blue” Δgi. The GC populations with red Δgi, even in dwarf galaxies, are twice as extended as the stars, suggesting that formation or survival mechanisms favor the outer regions. We find a tight correlation between R

e,gc and the total number of GCs, with intrinsic scatter ≲0.1 dex spanning two and three orders of magnitude in size and number, respectively. This holds for both red and blue subpopulations, albeit with different slopes. Assuming that N

200, while the blue GC systems in massive galaxies can have sizes as large as ∼10% R

e,gc is also found, with lower-density environments exhibiting more extended GC systems at fixed mass.

Published: May 2024

Abstract
Auroral kilometric radiation (AKR) is a widely existing strong radio emission from the Earth’s magnetosphere and is generated by suprathermal (1–10 keV) electrons in the polar cavity. Previous works have demonstrated that AKR can contribute to the coupling of the magnetosphere–ionosphere–atmosphere, but its relation to the interplanetary magnetic field (IMF) has not been studied so far. Here, we examine the data of Van Allen Probes and identify a total of 5000 AKR events from 2012 October to 2019 July. Most AKR events (4282) correspond to the dominant parallel component

of IMF. There are the most (1391) events in 2018 (the solar minimum year) and the least (258) events in 2014 (the solar maximum year), corresponding to more (less) occurrences for the longer duration (> 30 minutes) of southward IMF (B

z
< 0) in 2018 (2014). In the Earth’s Northern Hemisphere, there are the most (865) events in the autumn (August–October), corresponding to dominant B

x
< 0. In the Earth’s Southern Hemisphere, there are the most (830) events in the autumn (February–April), corresponding to dominant B

x
> 0. The probable reason for the above results is that the longer duration of B

z
< 0 can yield the longer magnetic reconnection, and the dominant B

x
< 0 (B

x
> 0) is favorable for the single-lobe magnetic reconnection in the northern (southern) hemisphere, allowing more suprathermal electrons into the polar source cavity and generating more AKRs. These current results suggest that IMF is very important for the occurrence of AKR and can be widely applied to similar auroral radio emissions in other magnetized planets of the solar system.
A Report on Stellar Companion Mass Estimates within Our Solar Neighborhood
Authors: Kumar Sangeeta , Salama Maïssa 
Published: May 2024

Abstract
We present mass estimates and companion demographics on stellar multiples within 25 pc, using a survey of stars of all spectral types done by Robo-AO and supplemented by Gaia. The survey combined direct imaging by Robo-AO, a robotic adaptive optics instrument for 2 m class telescopes, to detect tight companions (<4″ separation) and with Gaia astrometry to detect wider co-moving companions. We estimated the masses for 267 companions using empirical relations and, for a subset of 97, dynamical mass estimates. We utilized previous mass–magnitude models using contrasts measured from Gaia and Robo-AO to estimate the mass and also used the orvara python package, a Markov Chain Monte Carlo orbit fitter using the companion astrometry and Hipparcos-Gaia proper motion accelerations, to estimate dynamical masses. We compare agreements and discrepancies in mass estimates from these two methods.
Pwyll and Manannán Craters as a Laboratory for Constraining Irradiation Timescales on Europa
Authors: Davis M. Ryleigh , Brown Michael E. 
Published: May 2024

Abstract
We examine high-spatial-resolution Galileo/Near-Infrared Mapping Spectrometer observations of the young (∼1 My–∼20 My) impact features, Pwyll and Manannán craters, on Europa’s trailing hemisphere in an effort to constrain irradiation timescales. We characterize their composition using a linear spectral modeling analysis, and find that both craters and their ejecta are depleted in hydrated sulfuric acid relative to nearby older terrain. This suggests that the radiolytic sulfur cycle has not yet had enough time to build up an equilibrium concentration of H2SO4, and places a strong lower limit of the age of the craters on the equilibrium timescale of the radiolytic sulfur cycle on Europa's trailing hemisphere. Additionally, we find that the dark and red material seen in the craters and proximal ejecta of Pwyll and Manannán show the spectroscopic signature of hydrated, presumably endogenic salts. This suggests that the irradiation-induced darkening and reddening of endogenic salts thought to occur on Europa’s trailing hemisphere has already happened at Pwyll and Manannán, thereby placing an upper limit on the timescale by which salts are irradiation reddened.
A Master in Tone(s): Markson’s Interconnective, Abstract Art in Wittgenstein’s Mistress
Authors: Noël Sophie 
Published: May 2024

Le style fragmenté de Wittgenstein’s Mistress de David Markson est inspiré en partie du Tractatus Logico-Philosophicus de Ludwig Wittgenstein, fait d’une multitude de courts paragraphes cependant liés par une cohorte inhabituelle de marques de cohésion, lesquelles semblent refléter l’un des thèmes essentiels du roman, celui des « connexions » entre les choses. Cet article analyse la façon dont certains mots ou segments de phrases, ou encore certains motifs, tissent des liens presque en dehors du sens pour former un réseau tirant le lecteur vers un degré d’abstraction qui déroute, et qui reflète ou qui incarne la réflexion menée sur les rapports entre langage et représentation. Après une étude du génitif saxon dans le titre Wittgenstein’s Mistress, qui nous semble être à l’instar du double mécanisme de connexion et d’abstraction dans le roman, cet article examine la manière dont les « connexions » mènent le lecteur vers une éventuelle production de sens tout en faisant en sorte de l’en éloigner. Ceci permet de mettre en lumière la variété de tons à l’œuvre dans Wittgenstein’s Mistress, dans un savant équilibre entre le figuratif et l’abstrait, le comique et le tragique, les tribulations du corps et les détours de la pensée.
L’automobile, objet géopolitique ? Une lecture des débats sur la place de la voiture dans la région francilienne
Authors: Commenges Hadrien , Debrie Jean , Maulat Juliette 
Published: May 2024

La place de l’automobile en ville est au cœur de nombreux débats largement médiatisés. Si ces débats révèlent des conflits partisans entre personnalités et groupes politiques, ils sont aussi marqués par des oppositions et contradictions entre échelles de planification et de régulation, corollaire d’une géographie de la dépendance automobile. Cet article a pour objectif d’explorer la dimension spatiale de ces conflits dans la région francilienne. Après avoir caractérisé la gouvernance de la métropole francilienne automobile, trois études de cas sont traitées : la fermeture des berges de Seine à Paris, les débats sur la requalification du boulevard périphérique, la mise en place de la Zone à faibles émissions dans le périmètre métropolitain. Ces études de cas permettent d’identifier une géopolitique de l’automobile caractérisée par une forte politisation du débat, une absence de consensus entre acteurs de l’action publique locale (nationale, régionale, intercommunale et communale) et enfin une fragmentation et une différenciation spatiale des politiques publiques sur cet objet automobile.
Le Grand Paris Express, une politique de gentrification ?
Authors: Clerval Anne , Wojcik Laura 
Published: May 2024

Le Grand Paris Express est un projet d’aménagement de grande ampleur, qui implique la construction d’un nouveau réseau de métro, mais aussi de 68 futurs quartiers de gare, censés concentrer l’effort de production de logement pour les années à venir dans la région parisienne. C’est un chantier d’une ampleur inédite dont cet article analyse la programmation en termes de logement par différents niveaux de décision. Il apparaît que la majorité des logements neufs construits ou prévus dans ces quartiers seront des logements privés en accession à la propriété, bénéficiant d’une accessibilité inégalée jusqu’ici dans des banlieues souvent mal reliées au reste de l’agglomération. La part des logements sociaux prévus est variable localement et imprécise. Plus encore, des maires mobilisent les projets ANRU pour accélérer le changement social dans les futurs quartiers de gare. Les nouveaux quartiers de gare apparaissent comme une politique de gentrification qu’aucune intervention de la Métropole du Grand Paris ne vient contrecarrer.
