Published: November 2024

The present study investigated the feasibility, ideologies and setbacks regarding the efficacy of the transition of English language teaching from communicative language teaching (CLT) approach to post-method pedagogy in secondary level English as a foreign language (EFL) classrooms of Bangladesh depicting the teachers’ insights on the scopes and uses of post-method in EFL teaching. The study followed a qualitative approach, conducting in-depth interviews with fifteen secondary EFL teachers to explore their perceptions and experiences of both CLT and post-method. The findings revealed that while CLT is tentatively sound, its practical implementation has been hindered by over-reliance on traditional grammar-translation (GT) methods, inadequate training, and systemic support issues. Contrariwise, postmethod offers a flexible and context-sensitive pedagogical approach that allows for adapting teaching methods to meet the students’ particular needs. However, challenges such as the lack of formal guidelines, resource constraints, and traditional confrontation to alteration pose substantial barriers to its effective implementation. Integrating AI tools can offer promising opportunities to support post-method pedagogies by creating adaptive learning environments and enhancing student engagement. The study recommended intensive professional development workshops, institutional supports, and teachers’ digital literacy with the skills needed for this pedagogical shift. By addressing these issues, educational stakeholders can foster a more effective and contextual EFL teaching at the secondary level of Bangladesh.

Sistem Pendukung Keputusan atau Decision Support System (DSS) dapat menentukan hubungan antara kriteria, alternatif dan sebuah peristiwa  Sistem pendukung keputusan adalah sistem yang memberikan informasi, pemodelan, manipulasi data yang bersifat interaktif bisa disimpulkan bahwa sistem pendukung keputusan merupakan metodologi untuk membantu pengambilan keputusan -yang bersifat interaktif. Proses pendataan yang dilakukan di Desa Kadi Pada Kecamatan Loura, Kota Tambolaka Kabupaten Sumba Barat Daya Provinsi Nusa Tenggara Timur masih menggunakan cara manual yaitu dengan mengisi formulir dalam bentuk kertas dan diseleksi satu persatu tanpa menggunakan alat bantu seperti sistem. Tentunya hal ini akan memperlambat kinerja panitia penyeleksi penerima bantuan sosial karena membutuhkan waktu yang lebih lama untuk menerima hasil seleksi, adanya hasil yang tidak akurat dan tidak tepat sasaran serta sulitnya melakukan pencarian data sehingga cara ini dianggap tidak optimal untuk digunakan. Ditinjau dari permasalahan yang ada, maka dibutuhkan suatu sistem yang berfungsi untuk memecahkan permasalahan tersebut agar proses seleksi penerima bantuan sosial tidak memakan waktu dan dinilai lebih optimal.Hasil perhitungan menggunakan metode SAW diperoleh rekomendasi nama-nama penerima program bantuan sosial berdasarkan perangkingan. Selain itu berdasarkan hasil pengujian sistem ini berjalan sesuai dengan fungsinya sehingga bantuan sosial dapat tersalurkan dengan tepat sasaran.

Piperine is a phenolic compound in black pepper (Piper nigrum Linn) and Piper longum. It has been used in traditional medicine and has many pharmacological properties. However, its poor solubility in water has hindered the development of drugs with piperine as the main ingredient. In this study, solid dispersions of piperine were formulated using hydrophilic polymer (PVP) and hydrophobic polymer (Eudragit) to improve its dissolution rate and antioxidant activity. The solid dispersions were prepared using solvent evaporation techniques with various ratios of pure piperine to polymer (2:1, 1:1 and 2:1, w/w). FESEM, DSC, XRD, and FT-IR characterized the resulting solid dispersions of piperine. The dissolution rates were measured in distilled water, and antioxidant activity was evaluated using DPPH and FRAP free radical scavenging assays. The physicochemical characterization results indicated that solid dispersions with PVP and Eudragit had properties different from those of pure piperine. The dissolution test results showed that the solid dispersions with PVP (2:1) and Eudragit (1:1) exhibited the best dissolution rates, at 40.32 and 38.02 %, respectively. Furthermore, PVP and Eudragit solid dispersions (2:1, 1:1) demonstrated a higher antioxidant capacity in scavenger DPPH and FRAP free radicals than other formulations. These findings suggest that both polymers can increase piperine solubility, leading to increased antioxidant activity. However, further studies are needed to understand the underlying mechanisms.
HIGHLIGHTS
In the present study, dissolution enhancement of piperine was achieved by the solid dispersion technique using polyvinyl pyrrolidone (PVP), and Eudragit showed good characterization in the diffraction peak intensity in the XRD analysis, lower melting point, and diminished endothermic peaks in the DSC analysis. FTIR spectroscopy analysis demonstrated no chemical interactions between pure piperine and the polymers, while FESEM analysis revealed significant changes in crystal morphology. Increasing piperine's dissolution rate can improve bioavailability and enhance antioxidant activity.

Numerical Simulation of Corrosive Flow in the Production End of Carbon Capture, Utilization, and Storage-Enhanced Oil Recovery Backflow Wastewater Pipeline
Authors: Hu Fangwen , Wang Lili , Fu Haipeng , Fu Shibo , Wang Huajie , Shi Jian , Li Dong
Published: November 2024

In a carbon capture, utilization, and storage-enhanced oil recovery (CCUS-EOR) system process, the high carbon dioxide content and high acid value of the fluid at the extraction end are treated at the wastewater treatment station and then flow through the transfer station of the gathering system. The reinjection system’s pipelines at the transfer station are prone to corrosion and leakage risks. A steady-state nonisothermal flow and corrosion model was established to examine this corrosive phenomenon by utilizing the principles of fluid dynamics and electrochemical corrosion. The study examined how flow velocity, temperature, pressure, and pH affected the pipeline’s corrosion. Simulation results showed flow velocity increased in specific places of both straight and curved pipeline sections. The velocity near the inner wall of curved portions was higher, making them more susceptible to cavitation damage. Faster flow rates, lower pH values, higher temperatures, and smaller pipeline diameters all contributed to increased corrosion on the inner walls of wastewater pipelines. The highest simulated corrosion rate was 8.3162 mm/a corresponding to the smallest pipeline diameter (100 mm), lowest pH (4), highest temperature (60°C), and highest flow rate (36.847 m/s). When designing the CCUS-EOR system, the nonmetallic pipeline should be given priority. If carbon steel metal pipelines are utilized, it is best to use larger-diameter materials in the engineering design. Additionally, procedures such as adding corrosion inhibitors to regulate pH values and lowering the temperature of wastewater conveyance might be explored to reduce corrosion on the pipeline’s inner walls.

Authors: Huang Shulin , Xie Kun , Li Xiaohong , Xu Xiangjin , Chen Pin
Published: November 2024

Introduction

Studies have suggested a potential association between patients who have both psoriasis and diabetes and liver damage. However, the exact nature of this link has not yet been fully established. The objective of the current study was to examine the potential exacerbation of liver damage due to the coexistence of psoriasis and type 2 diabetes mellitus (T2DM) and to explore the impact of interferon gene stimulating factor (STING) on related damage.

Material and methods

Four patient groups were recruited: normal individuals, individuals with diabetes, those with psoriasis, and those with both diabetes and psoriasis. Relevant indicators were collected to facilitate the investigation. Furthermore, a mouse model of psoriasis combined with T2DM was established. The expression levels of STING and inflammatory factors downstream of the pathway were detected in both the skin and liver tissues of the model mice.

Results

Based on our findings, patients with both psoriasis and T2DM exhibit abnormal liver function and increased STING expression in the skin (p < 0.05). In the in vivo experiments, liver tissues from model mice exhibited significantly elevated expression of STING and its downstream inflammatory factors, including NF-κB p65, interferon-β, interleukin (IL)-17A, and IL-23 (p < 0.05). The STING inhibitor-treated group displayed reduced skin damage and improved liver histopathology (p < 0.05).

Conclusions

The findings of the current study indicate that the STING inflammatory pathway is upregulated in the liver tissues of individuals with psoriasis and T2DM.
Mechanisms of Resistance: Informal Institutional Impediments to Japanese Postal Privatization
Authors: Maclachlan Patricia L.
Published: November 2024

Why has Japan failed to fulfill the mission of its 2005 postal privatization legislation? The answer is informal institutions that empower the postmasters within the electoral system and facilitate the mobilization of elites on behalf of anti-reformist goals. To support this claim, I analyze three such institutions: the postmasters’ ownership of postal facilities; the re-employment of former bureaucrats by the postal system and of top postal employees elsewhere in the system; and sales and vote-mobilization quotas. Theoretically, this study analyzes four sources of informal institutional resilience following formal institutional change: the heretofore understudied participation of officialdom in the introduction, communication, and enforcement of informal institutions; the establishment of such institutions prior to new formal rules; institutional duplication across economic sectors; and institutional complementarities.

El valor de lo «improductivo» y sus impactos laborales: la protección del tiempo extralaboral por la norma laboral
Authors: Miñarro Yanini Margarita
Published: November 2024

1. Resulta absolutamente pacífica la afirmación de que el tiempo de trabajo es una condición esencial vinculada al propio nacimiento del derecho del trabajo. Así, impulsada por la correspondiente reivindicación obrera acompañada de movilizaciones, inicialmente se estableció su limitación por el Real Decreto de 3 de abril de 1919 que, con carácter general, disponía que «la jornada máxima legal será de 8 horas al día, o 48 horas semanales, en todos los trabajos». Posteriormente, tras varias regulaciones «de ajuste», la Ley 4/1983 fijó la jornada máxima semanal en 40 horas, además de ampliar las vacaciones hasta el mínimo de 30 días naturales al año. Las modificaciones posteriores de la normativa general no han incidido en la dimensión cuantitativa del tiempo de trabajo, sino que se han centrado en la faceta cualitativa, en particular, en la flexibilización del tiempo de trabajo. Estos apuntes telegráficos sobre la evolución de la regulación de esta importante condición de trabajo muestran que, en su vertiente cuantitativa, ha experimentado pocos cambios, en contraste con los procesos productivos, en los que, de manera generalizada, la evolución ha sido drástica.

This study analyzed the incidence of syphilis among the male prison population in Brazil from 2000 to 2024. It emphasizes that syphilis, caused by Treponema pallidum, is a Sexually Transmitted Infection (STI) with high prevalence in this vulnerable group, primarily due to poor hygiene conditions and limited access to healthcare services. An integrative literature review was conducted, including eight articles that met the inclusion criteria of studies published between 2000 and 2024 specifically addressing syphilis in the male prison population. Articles focusing on other STIs without direct relevance and studies with inadequate methodologies were excluded. The search was performed in the databases PubMed, BVS, MedLine, and Scielo, using descriptors such as “syphilis,” “prison population,” and “Sexually Transmitted Infections (STIs).” The findings indicate a high incidence of syphilis, exacerbated by risk practices such as unprotected sex and the sharing of syringes, along with the absence of adequate health policies. The study highlights the urgent need for effective interventions, including systematic screening and health education, to control the spread of the disease and improve the quality of life for inmates. These measures are essential not only for the health of prisoners but also for preventing the transmission of syphilis to the broader population.

The era of development is racing against rationality to deal with problems and religious practices are put aside. The reality is th at even high intellectuals have not been able to properly control their emotions and spirituality. That way there is a need for training to increase spirituality in order to lead a good life. This study uses thematic interpretation with library research. From this study, according to Abdul Daem Al-Kaheel, dhikr has a connection with spiritual intelligence, this is found in the benefits of dhikr which gives peace of mind. And dhikr has a good impact on one of the members of the human body, namely the brain, where there is a very clear influence on brain signal emission when doing dhikr. At the end of the study, the writer realizes that this research is not perfect and certainly requires more in-depth analysis, regarding dhikr which is closely related to human life. so the researchers hope that there will be an in-depth study of dzikr that can be applied to humans in order to lead a more meaningful life.
Kriteria Mujtahid Perspektif Ibnu Arabi
Authors: Abshor Ulil
Published: November 2024

The scholars have formulated the criteria for a mujtahid. And among those criteria are puberty, having an adequate understanding of sharia sources, whether the Quran or hadith, and having a set of abilities to analyze those sharia sources. However, the criteria that have been formulated are, in Ibn Arabi's view, only secondary requirements. According to him, the primary requirement that a mujtahid must have is inner readiness. Departing from this, it is necessary to explain the concept of ijtihad from the perspective of Ibn Arabi and his views in several cases of fiqh. This type of research is literature and the method used is comparative inductive while the approach used is fiqh and Sufism. As a result, ijtihad is an effort to prepare the mind, where the mujtahid must achieve the maqam of piety. And with this devotion a person will be able and ready to receive the inspirations given by Allah to him. And among the rulings that are the result of Ibn Arabi's ijtihad is the status of taklif for people who are insane, have not yet reached puberty and are asleep. According to him, the position of mukallaf in this kind of situation is "al-barâ'ah", that is, they are independent of the obligations of the Shari'ah, but nevertheless they are still subject to the status of taklif with a different essence of the taklif. And it is in the form of liberation from taklif al-ibâhah or al-barâ'ah. and so it is not lifted. However, back to human character like an animal that is just a man with a sense. This is because Ibn Arabi views that the law on an obligation is based on the value of its sharia and not based on its reason. And this has legal consequences in some cases

An Atlantic influence on evaporation in the Orinoco and Amazon basins
Authors: Duque-Gardeazabal Nicolas , Friedman Andrew R. , Brönnimann Stefan
Published: November 2024

Abstract. Tropical South America’s hydroclimate is inﬂuenced by ocean-atmospheric oscillations. The physical mechanisms that tele-connect the Atlantic modes of variability with the soil moisture and evaporation of the region remain unclear. This study uses composites of reanalysis and satellite data to identify the processes linking land-surface anomalies and ocean modes. It shows that the Atlantic Meridional Mode (AMM) generates cross-equatorial wind anomalies that affect moisture convergence, in turn modifying the cloud cover, precipitation, radiation availability and hence evaporation. The anomalies have important geographical differences depending on the analysed season; they migrate from the east in Austral autumn towards central Amazon and western Orinoco in Austral spring. The Atlantic El Niño (Atl3) affects the Guianas and eastern Orinoco by means of pressure and trade wind variability. Evaporation is water- or energy-driven depending on the position of the Intertropical Convergence Zone (ITCZ), but the anomalies are controlled by the phase of each mode which alter water and radiation availability. Both Atlantic modes mainly impact regions different from those impacted by El Niño Southern Oscillation (ENSO), although northeast Brazil and the Guianas might experience overlapping effects. Therefore, these ocean-atmospheric modes impact the water and energy cycles and might inﬂuence regional climate extremes (e.g. droughts and ﬂoods), and are critical for achiving sustainable development (SDG).
Evaluating sensitivity of optical snow grain size retrievals to radiative transfer models, shape parameters, and inversion techniques
Authors: Dillon James W. , Donahue Christopher P. , Schehrer Evan N. , Hammonds Kevin D.
Published: November 2024

Abstract. The near-infrared (NIR) albedo of snow is controlled by optical snow grain size (ropt). Therefore, characterizing the spatial and temporal variability in ropt at the snow surface is critical for understanding melt timing and magnitude for water availability, and Earth’s energy budget towards future climates. While numerous studies have demonstrated estimates of ropt via optical instruments that span scales from in situ to satellites, they leverage differing retrieval techniques, radiative transfer models, and modeled snow grain shapes. Variation in these factors cause tremendous uncertainty in ropt retrievals, yet a thorough evaluation has yet to be conducted. To address this knowledge gap we conducted a laboratory bidirectional reflectance study, using NIR hyperspectral imaging (NIR-HSI) to retrieve grain size metrics for a wide variety of snow microstructures and evaluate them against micro-CT benchmarks. Towards enhanced ropt retrieval accuracy, we sought to determine 1) the optimal modeled snow grain shape, 2) the best-performing radiative transfer model, and 3) variability associated with retrieval techniques, spanning broadband, narrowband, multispectral, and hyperspectral approaches. Our results for optimizing grain shape parameters align with existing studies for the TARTES model, and we offer first recommendations for the SNICAR model. The retrieval technique also displayed considerable variation with the hyperspectral residual method performing best. Multispectral and single-band techniques were comparable to their hyperspectral counterparts at times, but this was attributed to the idealized laboratory conditions and high instrument signal-to-noise ratio. Following shape-optimization, the SNICAR and TARTES models produced the best results (median absolute error of 15.6–17.4 %, depending on technique), outperforming the AART model and the Random Mixture model. Towards a more direct comparison with albedo estimate error, we also evaluated the square root of ropt retrievals; median absolute error values ranged from 7.9–26.2 % depending on model and technique, with most pairings resulting in values < 15 %. Our results demonstrate that the accuracy of ropt retrievals is highly sensitive to the choice of retrieval technique, radiative transfer model, and grain shape parameters. To minimize error, each of these factors should be carefully selected in the context of the specific measurement. As NIR-HSI instruments and other NIR detectors become increasingly affordable and their resolution improve, the findings presented here provide guidance for improved ropt and snow albedo mapping across ground-based, aerial, and satellite platforms.
Overcoming barriers in long-term, continuous monitoring of soil CO2 flux: A low-cost sensor system

Published: November 2024

Abstract. Soil CO2 flux (Fs) is a carbon cycling metric crucial for assessing ecosystem carbon budgets and global warming. However, global Fs datasets often suffer from low temporal-spatial resolution, as well as from spatial bias. Fs observations are severely deficient in tundra and dryland ecosystems due to financial and logistical constraints of current methods for Fs quantification. In this study, we introduce a novel, low-cost sensor system (LC-SS) for long-term, continuous monitoring of soil CO2 concentration and flux. The LC-SS, built from affordable, open-source hardware and software, offers a cost-effective solution (~USD700), accessible to low-budget users, and opens the scope for research with a large number of sensor system replications. The LC-SS was tested over ~6 months in arid soil conditions, where fluxes are small, and accuracy is critical. CO2 concentration and soil temperature were measured at 10-min intervals at depths of 5 and 10 cm. The LC-SS demonstrated high stability and minimal maintenance requirements during the tested period. Both diurnal and seasonal soil CO2 concentration variabilities were observed, highlighting the system's capability of continuous, long-term, in-situ monitoring of soil CO2 concentration. In addition, Fs was calculated using the measured CO2 concentration via the gradient method and validated with Fs measured by the flux chamber method using the well-accepted LI-COR gas analyzer system. Gradient method Fs was in good agreement with flux chamber Fs, highlighting the potential for alternative or concurrent use of the LC-SS with current methods for Fs estimation. Leveraging the accuracy and cost-effectiveness of the LC-SS (below 10 % of automated gas analyzer system cost), strategic implementation of LC-SSs could be a promising means to effectively increase the number of measurements, spatially and temporally, ultimately aiding in bridging the gap between global Fs uncertainties and current measurement limitations.
Earth observation for Shrub Encroachment
Authors: Soubry Irini , Guo Xulin
Published: November 2024

Abstract. Woody plant encroachment (WPE) refers to the increase in density, cover, and biomass of trees and shrubs, affecting both the environment and economy. Many regions lack quantification of WPE, and its driving factors remain unclear. Shrub encroachment, involving woody plants up to 1.5 meters tall, is particularly challenging to quantify due to the lower height and coverage of shrubs. Remote sensing can address this by leveraging spectral and structural properties to improve shrub detection. Integrating accurate quantifications of shrub encroachment over time in models with a variety of potential driving factors can shed light on primary encroachment patterns and mechanisms, aiding local management efforts.

Abstract. Arctic sea ice plays a crucial role in studies of regional and global climate change. Satellite observations have shown that the extent of Arctic sea ice has been declining over the last four decades. However, long-term variations in Arctic sea ice thickness (SIT) have received less attention because SIT cannot be measured directly by satellite-based instruments. Here, we present a monthly Arctic SIT product based on multiple radar altimetry observations from ERS-2, Envisat, and CryoSat-2. To ensure the accuracy of the SIT retrievals, a novel data processing method is proposed, including leads detection, freeboard conversion to thickness, and inter-mission bias correction. Finally, the monthly SIT estimates for the Arctic Ocean from October 1995 to December 2023 are generated. The thickness estimates are posted on a 5 km resolution polar stereographic grid. The variations in Arctic SIT are analyzed in terms of spatial and temporal distributions. Furthermore, the SIT estimates are compared with observations from upward-looking sonars and airborne laser altimetry from Operation IceBridge, as well as seven publicly released Arctic SIT products. The validation results demonstrate that our SIT product has accuracy equivalent to existing products. The accuracy of our products varies from 0.2 m to 0.4 m according to the input satellite altimetry data. The SIT datasets are available on the Zenodo at https://doi.org/10.5281/zenodo.13699698 (Xiao et al., 2024).

Abstract. Interactions and feedback between components of the Earth system can have a significant impact on local and regional climate and its changes due to global warming. These effects can be better represented by regional Earth system models (RESMs) than by traditional stand-alone atmosphere and ocean models. Here, we present the RESM Geesthacht Coupled cOAstal model SysTem (GCOAST)-AHOI v2.0, which includes a new atmospheric component, the regional climate model Icosahedral Nonhydrostatic (ICON)-CLM, which is coupled to the Nucleus for European Modelling of the Ocean (NEMO) and the hydrological discharge model HD via the OASIS3-MCT coupler. The GCOAST-AHOI model has been developed and applied for climate simulations over the EURO-CORDEX domain. Two 11-year simulations from 2008 to 2018 of the uncoupled ICON-CLM and GCOAST-AHOI give similar results for seasonal and annual means of near-surface air temperature, precipitation, mean sea level pressure, and wind speed at a height of 10 m. However, GCOAST-AHOI has a cold sea surface temperature (SST) bias of 1–2 K over the Baltic and North seas that is most pronounced in the winter and spring seasons. A possible reason for the cold SST bias could be the underestimation of the downward shortwave radiation at the surface of ICON-CLM with the current model settings. Despite the cold SST bias, GCOAST-AHOI was able to capture other key variables well, such as those mentioned above. Therefore, GCOAST-AHOI can be a useful tool for long-term climate simulations over the EURO-CORDEX domain. Compared to the stand-alone NEMO3.6 forced by ERA5 and ORAS5 boundary forcing, GCOAST-AHOI has positive biases in sea ice fraction and salinity but negative biases in runoff, which need to be investigated further in the future to improve the coupled simulations. The new OASIS3-MCT coupling interface OMCI implemented in ICON-CLM adds the possibility of coupling ICON-CLM to an external ocean model and an external hydrological discharge model using OASIS3-MCT instead of the YAC (Yet Another Coupler). Using OMCI, it is also possible to set up a RESM with ICON-CLM and other ocean and hydrology models possessing the OASIS3-MCT interface for other regions, such as the Mediterranean Sea.
On the use of streamflow transformations for hydrological model calibration

Abstract. The calibration of hydrological models through the use of automatic algorithms aims at identifying parameter sets that minimize the deviation of simulations from observations (often streamflows). Further, the choice of objective function (i.e. the criterion or combination of criteria for optimization) can significantly impact the parameter set values identified as optimal by the algorithm. This article discusses how mathematical transformations, which are sometimes applied to the target variable before calculating the objective function, impact model simulations. Such transformations, for example square root or logarithmic, aim at increasing the weight of errors made in specific ranges of a hydrograph. We show in a catchment set that the impact of these transformations on the obtained time series can sometimes be different from their expected behaviour. Extreme transformations, such as squared or inverse squared transformations, lead to models that are specialized for extreme streamflows but show poor performance outside the range of the targeted streamflows and are less robust. Other transformations, such as the power 0.2 and the Box–Cox and logarithmic transformations, can be categorized as more generalist and show good performance for the medium range of streamflows, along with acceptable performance for extreme streamflows.
