Inspeksi adalah sebuah aktivitas pemeliharaan peralatan yang digunakan dalam lingkup produk dan jasa perusahaan. Terkait dengan aspek lingkungan kerja sekitar, inspeksi merupakan pemeriksaan secara visual terhadap suatu peralatan untuk meyakinkan peralatan tersebut dalam kondisi baik untuk dioperasikan, serta tidak ada kerusakan fisik atau berkurangnya fungsi dan ukuran peralatan yang ada. Di industri minyak dan gas bumi kerugian yang terjadi akibat korosi berdampak pada penurunan kualitas material, kerugian finansial dan kerugian terhadap keselamatan lingkungan sekitar. Oleh karena itu perlu dilakukan inspeksi terhadap suatu fasilitas peralatan yang ada berdasarkan tingkat risiko Risk Based Inspection (RBI) yang akan mengarahkan peneliti menggunakan metode untuk menghitung tingkat laju korosi dan mengetahui sisa waktu operasi dan program inspeksi. Pemeriksaan ini khusus pada fasilitas pipa penyalur gas D : 10â€, D : 6â€ & D : 8â€ dengan fluida Liquid Petroleum Gas (LPG) yang dilakukan saat kondisi pipa sedang dalam kondisi operasi atau disebut sebagai â€œOn Stream Inspectionâ€. Sehingga pemeriksaanÂ ini perlu mendapatkan perhatian khusus untuk tetap menjaga kehandalan fasilitas pipa penyalur gas dalam kondisi baik.Â Â Kata kunci : Inspeksi, Korosi, RBI, Sisa waktu operasi.

El artista como productor. El autor como productor

Published: November 2024

El autor como productor es un discurso de Benjamin, en su 90 aniversario vale la pena preguntarse: ¿qué tan vigente o anacrónico es este texto frente a la digitalización de las artes? En este artículo, se retoman las técnicas pedagógicas del teatro brechtiano, las cuales son las que originalmente Benjamin presenta como clave por medio de las cuales el autor puede apropiarse de sus medios de producción, y se busca responder la pregunta: ¿qué tanto es consciente el artista de su labor como autor y por consiguiente como productor? Para esto se analiza la película escrita por Brecht Hangmen also die!, para entender el uso cinematográfico de su técnica y a partir de ahí se estudia su posible uso homogéneo en Hollywood. Con este contexto pedagógico del audiovisual, se hace una propuesta de un cortometraje, cuyo escrito usa premeditadamente la propuesta brechtiana para apropiarse del objetivo de la producción.

Bauhinia forficata
in terms of responsiveness and dependence to mycorrhiza

ABSTRACT

The benefits promoted by arbuscular mycorrhizal fungi (AMF) to forest species seedlings include higher growth rate, better nutrition, and higher survival rates. Inoculation with AMF may facilitate revegetation of degraded lands, although it depends on symbionts and environmental conditions, such as soil P availability. In this sense, the lack of information justifies the carrying out of studies of this nature. We investigated the dependence and responsiveness of two forest species native to the Atlantic Forest, Pseudobombax grandiflorum and Bauhinia forficata, to different AMF inocula (isolated AMF species, Dentiscutata heterogama, DH, Gigaspora margarita, GM, Rhizophagus clarus, RC, mixed inoculum with these former three AMF species, MI) compared to the uninoculated control (UC), combined with different P doses applied to the substrate (0, 24, 71, 213, and 650 mg kg
-1
), under greenhouse conditions. We evaluated root colonization, growth, and nutritional variables for Pseudobombax grandiflorum and Bauhinia forficata, 112 and 116 days after sowing with pre-germinated seeds, respectively. Native forest species exhibited different degrees of mycorrhizal dependence. The highest mycorrhizal dependence of P. grandiflorum seedlings was indicated by significant benefits, both growth and nutritional, promoted by innoculation treatments, under fertilization with the intermediate dose of P (213 mg kg
-1
). In fact, under this P dose, seedlings responded to a maximum increase in biomass in the GM treatment and maximum concentration of P and N in the shoots in the UC and DH treatments, respectively. The lowest mycorrhizal dependence of B. forficata seedlings was highlighted by significant growth benefits promoted by inoculation treatments under the lowest doses of P (24 or 71 mg kg
-1
). Under this P dose, we observed seedlings with maximum value of the root:shoot ratio in most of the types of inoculation and also higher values of biomass and height in the MI treatment. The responsiveness in terms of increase in growth and nutritional variables varied depending on the forest species, the dose of P applied to the substrate, and the AMF type of inoculum used. Root biomass and total dry biomass, mainly, should preferably be included in future studies with the same objective as the present study, as they were more relevant to point out the differences between treatments, in comparison with the variables associated with nutritional variables.

Published: November 2024

BACKGROUND
Metabolic dysfunction-associated fatty liver disease (MAFLD) is one of the main chronic liver diseases. However, the roles of mitochondrial carnitine palmitoyl transferase-II (CPT-II) downregulation and liver cancer stem cell (LCSC) activation remain to be identified.
AIM
To investigate the dynamic alterations in CPT-II inactivity and LCSC activation during the malignant progression of MAFLD.
METHODS
Dynamic models of mouse MAFLD were generated via the consumption of a high-fat diet or the addition of 2-fluorenylacetamide for hepatocarcinogenesis. The mice were divided into groups on the basis of hematoxylin and eosin staining. Biochemistries, CPT-II, intrahepatic T cells, and LCSCs were determined and confirmed in clinical samples. The mitochondrial membrane potential (MMP) was analyzed. Differentially expressed genes were screened via RNA sequencing and enriched in KEGG pathways or GO functions.
RESULTS
Dynamic models of MAFLD malignant transformation were successfully generated on the basis of pathological examination. Hepatic lipid accumulation was associated with the loss of mitochondrial CPT-II activity and alterations in the MMP, with decreases in liver CD3+ or CD4+ T cells and increased AFP levels. In the lipid accumulation microenvironment, mitochondrial CPT-II was inactivated, followed by aberrant activation of CD44+ or CD24+ LCSCs, as validated in MAFLD or hepatocellular carcinoma patient samples. In terms of mechanism, the biological process category focused mainly on the metabolic regulation of cells in response to external stimuli. The enriched molecular functions included protein binding, cell apoptosis, and cell proliferation.
CONCLUSION
CPT-II inactivity promotes the malignant progression of MAFLD via the loss of innate immune function and abnormal LCSC activation.
On Bayes factors for hypothesis tests
Authors: Klauer Karl Christoph , Meyer-Grant Constantin G. , Kellen David 
Published: November 2024

Abstract
We develop alternative families of Bayes factors for use in hypothesis tests as alternatives to the popular default Bayes factors. The alternative Bayes factors are derived for the statistical analyses most commonly used in psychological research – one-sample and two-sample t tests, regression, and ANOVA analyses. They possess the same desirable theoretical and practical properties as the default Bayes factors and satisfy additional theoretical desiderata while mitigating against two features of the default priors that we consider implausible. They can be conveniently computed via an R package that we provide. Furthermore, hypothesis tests based on Bayes factors and those based on significance tests are juxtaposed. This discussion leads to the insight that default Bayes factors as well as the alternative Bayes factors are equivalent to test-statistic-based Bayes factors as proposed by Johnson. Journal of the Royal Statistical Society Series B: Statistical Methodology, 67, 689–701. (2005). We highlight test-statistic-based Bayes factors as a general approach to Bayes-factor computation that is applicable to many hypothesis-testing problems for which an effect-size measure has been proposed and for which test power can be computed.

Abstract
Metals in the diffuse, ionized gas at the boundary between the Milky Way’s interstellar medium (ISM) and circumgalactic medium, known as the disk–halo interface (DHI), are valuable tracers of the feedback processes that drive the Galactic fountain. However, metallicity measurements in this region are challenging due to obscuration by the Milky Way ISM and uncertain ionization corrections that affect the total hydrogen column density. In this work, we constrain ionization corrections to neutral hydrogen column densities using precisely measured electron column densities from the dispersion measures of pulsars that lie in the same globular clusters as UV-bright targets with high-resolution absorption spectroscopy. We address the blending of absorption lines with the ISM by jointly fitting Voigt profiles to all absorption components. We present our metallicity estimates for the DHI of the Milky Way based on detailed photoionization modeling of the absorption from ionized metal lines and ionization-corrected total hydrogen columns. Generally, the gas clouds show a large scatter in metallicity, ranging between 0.04 and 3.2 Z
⊙, implying that the DHI consists of a mixture of gaseous structures having multiple origins. We estimate the inflow and outflow timescales of the DHI ionized clouds to be 6–35 Myr. We report the detection of an infalling cloud with supersolar metallicity that suggests a Galactic fountain mechanism, whereas at least one low-metallicity outflowing cloud (Z < 0.1 Z
⊙) poses a challenge for Galactic fountain and feedback models.
JWST Resolves Collision-induced Absorption Features in White Dwarfs

Published: November 2024

Abstract
Infrared-faint white dwarfs are cool white dwarfs exhibiting significant infrared flux deficits, most often attributed to collision-induced absorption (CIA) from H2–He in mixed hydrogen–helium atmospheres. We present James Webb Space Telescope (JWST) near- and mid-infrared spectra of three such objects using Near-Infrared Spectrograph (0.6–5.3 μm) and Mid-Infrared Instrument (5–14 μm): LHS 3250, WD J1922+0233, and LHS 1126. Surprisingly, for LHS 3250, we detect no H2–He CIA absorption at 2.4 μm, instead observing an unexpected small flux bump at this wavelength. WD J1922+0233 exhibits the anticipated strong absorption feature centered at 2.4 μm, but with an unexpected narrow emission-like feature inside this absorption band. LHS 1126 shows no CIA features and follows a λ
−2 power law in the mid-infrared. LHS 1126's lack of CIA features suggests a very low hydrogen abundance, with its infrared flux depletion likely caused by He–He–He CIA. For LHS 3250 and WD J1922+0233, the absence of a 1.2 μm CIA feature in both stars argues against ultracool temperatures, supporting recent suggestions that infrared-faint (IR-faint) white dwarfs are warmer and more massive than previously thought. This conclusion is further solidified by Keck near-infrared spectroscopy of seven additional objects. We explore possible explanations for the unexpected emission-like features in both stars, and temperature inversions above the photosphere emerge as a promising hypothesis. Such inversions may be common among the IR-faint population, and since they significantly affect the infrared spectral energy distribution, this would impact their photometric fits. Further JWST observations are needed to confirm the prevalence of this phenomenon and guide the development of improved atmospheric models.

Abstract
The measurement of continuum time lags in lensed quasars can effectively probe the accretion physics of quasars. This is because microlensing observations of lensed quasars can provide constraints on the half-light radii of quasar accretion disks. By combining the microlensing results with time lag measurements, one can, for the first time, estimate the propagation velocity of the physical process that drives interband time lags and cross correlations among disk emission (i.e., in UV/optical bands). In this study, we perform the disk reverberation mapping study for the well-studied lensed quasar, Q0957+561. The cross correlation between the Zwicky Transient Facility g and r bands was measured; the g variations lead the r ones by 6.4 ± 2.6 days in the rest frame. In combination with the half-light radius from the existing literature, we find that the propagation velocity of the variability mechanism should be

times the speed of light. We discuss the possible outcomes of this result. Similar studies can be applied to other lensed quasars by utilizing the Legacy Survey of Space and Time observations.

Abstract
We investigated two consecutive solar eruption events in the solar active region 12994 at the solar eastern limb on 2022 April 15. We found that the flare loops formed by the first eruption were involved in the second eruption. During the initial stage of the second flare, the middle part of these flare loops (E-loops) erupted outward along with the flux ropes below, while the parts of the flare loops (I-loops1 and I-loops2) on either side of the E-loops first rose and then contracted. Approximately 1 hr after the eruption, the heights of I-loops1 and I-loops2 decreased by 9 Mm and 45 Mm, respectively, compared to before the eruption. Their maximum descent velocities were 30 km s−1 and 130 km s−1, respectively. The differential emission measure results indicate that the plasma above I-loops1 and I-loops2 began to be heated about 23 minutes and 44 minutes after the start of the second flare, respectively. Within ∼20 minutes, the plasma temperature in these regions increased from ∼3 MK to ∼6 MK. We proposed an adiabatic heating mechanism where magnetic energy would be converted into thermal and kinetic energy when the prestretched loops contract. Our calculations show that the magnetic energy required to heat the two high-temperature regions are 1029–1030 erg, which correspond to a loss of field strength of 2–3 G.
