Authors: Mardiyani Mardiyani , Lestari Sinta , Febriansyah Rian , Firmansyah Egi Arvian 
Published: November 2024

Background: The firm value is a crucial metric that accurately represents financial performance. Various elements influence the worth of a company inside the framework of a constantly changing worldwide market. These factors are crucial for managers, investors, and stakeholders. Establishing public trust is a crucial factor in enabling success. In 1998, Indonesia faced a monetary crisis triggered by inadequate implementation of corporate governance. Having a CGPI as a business controller enhances the comprehension of the many aspects that impact the value of a firm. Implementing GCG is an essential strategy for continually enhancing the value of a business.
Objective: This research examines how the CGPI acts as a moderator, influencing the impact of profitability, dividend policy, and earnings management on firm value.
Methods: This study applies a quantitative approach using purposive sampling. The object of research is companies listed on the CGPI, with data sources from the IDX and the results of the IICG assessment from 2017-2021. Methods of data analysis using Moderate Regression Analyze (MRA) with SPSS 29.
Results: The research results demonstrate how businesses inform investors and lend credibility to signalling. This suggests that characteristics that influence a firm's value might be used as indicators to make decisions regarding investments. Moreover, the utilization of CGPI indicates improved financial results, suggesting efficient and clear earnings management. The CGPI effectively prevents managers from engaging in opportunistic earnings management.
Conclusion: Various factors, including profitability, dividend policy, and earnings management, impact a business's value. Establishing the CGPI is essential to encouraging sustainable growth in corporate valuation.

Examining Social Insurance Perceptions and Attitudes among Zimbabwean Informal Sector Workers: A Study on Providing Social Protection to the Disenfranchised
Authors: Mutanda Bronson , Nomlala Bomi Cyril 
Published: November 2024

Background: Given the rate at which the labour force in Zimbabwe's informal sector continues to evolve, steps need to be taken to promote a culture where employees contribute towards their social insurance. Social insurance is significant since it helps informal sector workers to prepare for life's predictable and unpredictable events, such as retirement, unemployment, old age, incapacity, death and health challenges.
Objective: Motivated by the increasing number of workers in the informal sector in Zimbabwe, this study aimed to explore the attitudes and perceptions of this group of people towards social insurance coverage and investigate strategies for extending social insurance to informal sector workers.
Method: To achieve the objectives, convenience sampling was employed, and 115 questionnaires from informal sector workers of Jerera Growth Point were analyzed. Data collection involved the use of a questionnaire. A convergent parallel research design was adopted, with quantitative and qualitative data being analyzed to gain insight into the perception of informal sector workers.
Results: The study's findings demonstrate that workers in the informal economy have a negative attitude towards social insurance coverage. Additionally, the results demonstrate that the age of informal sector workers affects their intention to contribute towards social insurance coverage. The results also demonstrate that employees in the informal sector need more basic knowledge about social insurance and how to apply for social insurance coverage.
Conclusion: The study concluded that workers in the informal economy lack faith and confidence in those who provide social insurance services, explaining why they perceive social insurance coverage negatively.

Eggplant is a vegetable grown worldwide, and due to quality standards, large amounts of biomass are generated after harvest. Biomass is considered a source of bioactive compounds with antioxidant properties. Therefore, this research aimed to evaluate microencapsulated alkaloids&#039; bioaccessibility (BA) and antioxidant capacity from eggplant fruit biomass. Eggplant biomass was collected, and the total alkaloid content, antioxidant capacity, and alkaloid profile were determined before and after the digestion in vitro for encapsulated and non-encapsulated alkaloids. The bioaccessibility of microencapsulated alkaloids (12 % BA) increased three-fold compared to non-encapsulated (4 %BA). The antioxidant capacity of digested microcapsules measured by ORAC and TEAC assays was increased (30 and 8 µmol TE/g powder, respectively), and their bioaccessibility was higher than non-encapsulate alkaloids. Solamargine and solasonine decreased during in vitro digestion by 17 and 15 %BA, respectively. However, microencapsulation showed the protection of these alkaloids during in vitro digestion. This study demonstrates that microencapsulated alkaloids from eggplant biomass manage to protect bioactive compounds from in vitro digestion, having antioxidant potential mainly through hydrogen atom transfer. Therefore, microencapsulation represents an alternative to protect alkaloids and give added value to eggplant plant biomass.

Study Assesses Effects of Carbon Dioxide on Drilling-Fluid Performance in CCS Wells
Authors: Carpenter Chris 
Published: November 2024

_
This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 217711, “CCS Well-Control Impact of CO2 on Drilling-Fluid Performance,” by Jan O. Skogestad, SPE, Blandine Feneuil, SPE, and Elie N’Gouamba, SPE, SINTEF, et al. The paper has not been peer reviewed.

_
Drilling carbon-dioxide (CO2) storage wells is a task expected to involve handling an influx of CO2 into the drilling fluid. In the study described in the complete paper, experimental characterization of density, rheology, phase envelope, hydrate formation, and drilling-fluid stability are performed on drilling fluids mixed with CO2 for relevant pressures and temperatures. Based on these experiments and verified thermodynamic model descriptions, local models for properties of drilling-fluid/CO2 mixtures were developed and integrated into an existing drilling software suite.

Requirements for Enhanced Well-Control Software
Well-control-evaluation software based on sophisticated and verified models of the drilling-fluid/gas interaction in the wellbore plays an important role in planning drilling operations. The software also can be used to evaluate the strategy for circulating out a kick and regaining control of the well. When drilling infill wells into CO2 storage sites, this software must be able to process kicks originating from both CO2 and natural gas influx.
To achieve this ability, knowledge gaps related to the interaction of CO2 and drilling fluid must be closed. Hydraulic-flow models need to be enhanced with local models that capture the unique properties of CO2 and how it affects drilling-fluid performance.
Starting from carefully devised experimental campaigns, the authors developed local models for drilling-fluid/CO2 interaction that were integrated into an existing hydraulic flow model. A well-control-evaluation product for use during planning and execution of infill drilling operations into CO2 storage reservoirs may then be built using the upgraded models.
Experimental methods, equipment, and setup are detailed in the complete paper.

Experimental Results
Bubblepoints.
Bubblepoint experiments in the base oil have been performed with CO2 weight content from 4 to 50% of the total weight of the mixture and at room temperature and 50 and 100°C. All measurements have been repeated at least once.
At room temperature, CO2 can be dissolved in oil at mass fractions of up to approximately 50%. The bubblepoint increases when the temperature increases (i.e., the solubility decreases).
As with base oil, the solubility of oil-based drilling fluid (OBDF) decreases with temperature. The bubblepoint at room temperature with 25% of CO2 by weight of the mixture is approximately 60 bar, roughly the bubblepoint of pure CO2. Therefore, the maximal solubility of CO2 in OBDF is probably below 25%. To compare the measured solubility in base oil and in OBDF, the CO2 content relative to the base oil has been calculated using the OBDF composition provided by the manufacturer.
Technology Focus: Flow Assurance (November 2024)
Authors: Wilson Adam 
Published: November 2024

This year’s Flow Assurance Technology Focus provides a trio of papers, selected by ChampionX’s Celestina Kissi, concerning the use of advanced techniques in detection, mitigation, and risk calculation. SPE technical conferences and meetings remain a critical conduit for the transfer of forward-thinking research and insight to both project developers and field practitioners who make certain that production is optimized and that goals are met.
Paper SPE 216216 investigates asphaltene risks inherent in the gas-injection enhanced oil recovery (EOR) process. The authors’ research identifies what they term “stealth” asphaltenes, referring to asphaltenes detectable only by laser-light-scattering techniques and not by traditional microscopy. These asphaltenes are still flowable and can still pose risks to flow assurance.
In the second selection, SPE 218101, the authors delve into the risks posed by hydrate formation in water-alternating-gas EOR operations, particularly during changeover operations, an area in need of further research in the literature. Additionally, the authors explore the effect of natural gas composition on these phenomena.
Finally, paper SPE 218700 describes an operator’s development and deployment of a suite of cloud-based digital-twin tools designed to provide online, real-time calculation of scale risk and barrier health on a well-by-well basis. The complete paper includes four diverse case studies in which the described toolkit proved its value.
As the technology used in the field sharpens, it will simultaneously overcome long-standing obstacles and discover entirely new ones, such as the challenge posed in the first presented paper. SPE technical conferences will continue to ensure that the flow of innovation reaches the page and the field with equal effect.

Abstract

The urgent need for a non-invasive, universally applicable cancer detection method has never been more critical. In response to the pressing demand, we presents the discovery of phenyl-β-D-glucuronide, a natural compound, for tumor detection. Metabolized into phenol by β-glucuronidase, an enzyme prevalent in the tumor microenvironment, this compound led to elevated phenol levels in exhaled breath. Moreover, phenyl-β-D-glucuronide's exceptional bio-compatibility and minimal residual presence post-24 hours offer unparalleled advantages over conventional synthetic agents. Building upon this innovation, we created a cutting-edge cancer screening method known as phenyl-β-D-glucuronide induced breath analysis. Specifically, a handheld breath-analyzer is proposed to capture breath signals indicative of cancer presence. Preliminary animal tests, utilizing both subcutaneous and orthotopic tumors model, validated the effectiveness of our method in assessing various cancer risk, including gastric, lung, colon and liver cancers, with specificity/sensitivity/accuracy rates surpassing 94.3%; and minimal interference from other diseases. These impressive findings mark a significant step toward cancer detection, improving diagnosis and treatment outcomes universally.

Abstract

Background
Stress hyperglycaemia ratio (SHR) has been reported to be independently and significantly associated with various adverse cardiovascular events as well as mortality. Moreover, in-hospital heart failure following acute myocardial infarction has been demonstrated to account for majority of all heart failure (HF) cases with anterior myocardial infarction showing higher rates of HF. However, the association between SHR and in-hospital HF following an anterior ST-elevation myocardial infarction (STEMI) has not been reported earlier. Therefore, the present study aimed at identifying the relationship between SHR and in-hospital HF post STEMI.
Methods
In this retrospective study electronic health records of 512 patients who presented with anterior STEMI from 01 January 2022 to 31 January 2024 were analysed. Based on the development of in-hospital HF, the enrolled patients were stratified into two groups: Group I, comprising of 290 patients who developed in-hospital HF and Group II comprising of 222 patients who did not develop in-hospital HF. ROC and Multivariable logistic regression analyses were performed to assess the relationship between SHR and in-hospital HF.
Results
The results revealed that SHR is a significant independent predictor of in-hospital HF (OR: 3.53; 95%CI: 2.02–6.15; p < 0.001). Apart from SHR, the results also identified age, nosocomial pneumonia, ventricular fibrillation, LVEF, and NT-pro-BNP levels as other independent predictors. ROC analysis showed that SHR independently had a moderate discriminative power with AUC: 0.683, 95% CI 0.605–0.762; p = 0.04, which was almost comparable to the combined predictive value of other independent risk factors (AUC: 0.726, 95% CI 0.677–0.784). Noticeably, combining SHR and other identified independent predictors demonstrated a significant predictive power (AUC: 0.813, 95% CI 0.757–0.881; p = 0.01).
Conclusion
SHR is an independent predictor for in-hospital HF in anterior wall STEMI patients.

Published: November 2024

Abstract

Background: Various international institutions established key quality assurance guidelines for radiation therapy, focusing on treatment accuracy and equipment reliability. Despite international standards, the lack of an independent audit system in South Korea has led to quality management challenges in high-dose-rate brachytherapy, prompting this study to develop a precise source activity measurement system and regulatory MATLAB code.
Methods: Variations in Remote After-Loading System (RALS) models across institutions are considered, with Standard Imaging source holders and a CDX2000B electrometer used for accurate source strength measurements, focusing on maximum point accuracy. Mechanical accuracy checks involve assessing dwell position accuracy, reproducibility, and offset using self-developed phantoms with in-house MATLAB code, supported by EBT3 film for precise measurement and verification of radiation source positions and offsets.
Results: Measured data present the discrepancy between measured and calculated values, with uncertainty observed below 0.14%. Additionally, The developed in-house MATLAB code for film data analysis, utilizes grayscale window analysis for accurate identification of irradiated points, demonstrating minimal position and step size errors, affirming the precision of the method.
Conclusion: In this study, we developed an audit system integrating a source strength measurement system and mechanical accuracy check phantoms, utilizing a well-type chamber – electrometer setup and in-house MATLAB code. We achieved audit suitability with appropriate uncertainty, compatible across various Remote After-Loading Systems (RALS). Uncertainty assessments resulted in proposed expanded uncertainties (k = 2) of 2.72% and 2.71% for models 70010 and 72280. Based on these results, we plan to implement this audit system nationwide to comply with domestic regulations.

Published: November 2024

Abstract

Opisthorchis felineus is a feline pathogen with zoonotic potential that can cause opisthorchiasis and cholangiocarcinoma in humans. In Europe, endemic areas particularly include Eastern Europe and parts of Asia, such as Russia, Ukraine, and Kazakhstan. However, the parasite has also been sporadically detected in Germany and northern Poland. A seven-year-old female neutered European shorthair cat without any travel history presented in May 2023 with weight loss, anorexia and vomiting. The cat presented increased liver enzyme activity, hyperbilirubinemia and hyperammonemia, which was consistent with the suspected diagnosis of cholangitis with subsequent hepatoencephalopathy. Opisthorchis felineus was detected via routine cytological examination of bile smears, and PCR confirmed O. felineus. This is the first report of autochthonous O. felineus infection in Austria.

Abstract

The aging population faces a gradual decline in physical and mental capacities, with an increased risk of liver cirrhosis and chronic liver diseases leading to hepatic encephalopathy (HE). The intertwining of physiological manifestations of aging with the pathophysiology of HE significantly impairs cognitive ability, reduces quality of life, and increases mortality. Hence, effective therapeutic intervention is imperative. The present study investigated the impact of minimal HE (MHE) on cognitive impairment in an aging rat population by analyzing hippocampal proteome dynamics. For this purpose, an old MHE rat model was induced via thioacetamide. The label-free LC‒MS/MS method was employed to explore hippocampal proteomic changes and associated dysregulated biological pathways. A total of 1533 proteins were identified, and among these, 30 proteins were significantly differentially expressed (18 upregulated, and 12 downregulated). Three upregulated proteins, namely, fetuin-A, p23, and intersectin-1 were selected and validated for their increased expression via western blotting and immunofluorescence analysis, which confirmed the mass spectrometry results. These proteins have not been reported previously in MHE cases. We also identified the possible dysregulated biological pathways associated with the differentially expressed proteins via Metascape, a network analysis tool. We found that the differentially expressed proteins may be involved in the generation of precursor metabolites and energy, the neurotransmitter release cycle, positive regulation of dendritic spine development, chaperone-mediated protein folding and protein stabilization. This study highlights the potential mechanisms underlying neurological dysfunction in the aging population with MHE and identifies novel therapeutic targets for improved disease management.
