Authors: Muchtar Masruri , Puspita Desy , Amalia Euis
Published: August 2024

Due to the merger, Bank Syariah Indonesia (BSI) recorded total assets of IDR 240 trillion. This study examines whether there are differences between the pre-and post-merger in the financial performance of BSI in terms of liquidity, solvency, and profitability using Wilcoxon signed test and paired sample t-test. This study finds significant differences in the level of liquidity and profitability of BSI's financial performance, while there is no significant difference in the level of solvency. This result implies that BSI's efficiency in managing business increases; therefore, the operational costs might be reduced, and the operating income tends to grow. Although the financing-to-debt ratio (FDR) is moderate, BSI still needs to improve the effectiveness of its fund distribution. This study contributes to the literature on mergers and acquisitions in the banking sector, particularly for Islamic banks, by providing new insight into its impact on financial performance.

A new promise in conservative surgery
Authors: Casoni Paolo
Published: August 2024

A new protagonist appears in the phlebology scene: HIFU (High Intensity Focused Ultrasound). It is a new non-invasive thermo-ablative method to treat superficial venous reflux: an ultrasound imaging guides a focused ultrasound energy. The technology was started since 2019 (A Obermayer conceived it and M Whitely applied it widely in phlebology), but it slowed down by Covid diffusion. Nowadays, it is better established, Paolo Casoni being probably one of the most universally recognized experts in the field. The interview aims to highlight some aspect of the HIFU experience, touching some non-cleared or even debatable details.
A recent article (Casoni P, et al. Phlebology 2024) stimulated a series of clinical and anecdotal questions that we asked Dr Paolo CASONI, protagonist of a therapeutic experience that allows a true "no touch" treatment on varicose veins, the maximum desire of doctors and patients. In addition, in contrast with current thinking, a conservative strategy is proposed, based on a pathophysiological conception, which is however questionable and still undemonstrated.

Therapeutic modulation of neuroinflammatory and apoptotic pathways by PEPITEM in an EAE model of multiple sclerosis
Authors: Alassiri Mohammed
Published: August 2024

Objective: To examine the therapeutic effects of PEPITEM on neuroinflammatory and apoptotic pathways in an Experimental Autoimmune Encephalomyelitis (EAE) model of Multiple Sclerosis (MS), focusing on the modulation of key biomarkers: SIRT1, NRF2, NF-κB p65, Bax, and Bcl2. Methods: We utilized a controlled experimental design involving five groups of female C57BL/6 mice, aged 9–12 months to assess the effects of PEPITEM administered therapeutically and prophylactically. Groups included a normal healthy mice group (G1), an EAE-induced group receiving scrambled peptide therapeutically (post-induction) (G2), an EAE-induced group treated with PEPITEM therapeutically (G3), and an EAE-induced group given scrambled peptide (G4) prophylactically or, an EAE-induced group treated with PEPITEM prophylactically (G5). Following induction and PEPITEM treatment, weight and EAE scores were compared among the designated groups. Additionally, spinal cord tissues were harvested for protein lysate preparation and Western blot analysis quantified the expression levels of the selected biomarkers. Results: Analysis of the weight and EAE scores reveals that G3 and G5 exhibit trends toward recovery, potentially indicating the effectiveness of the treatment. Moreover, PEPITEM treatment significantly upregulated the expression of SIRT1 and NRF2, suggesting an enhanced neuroprotective and antioxidant response. Conversely, NF-κB p65 and Bax levels were notably decreased, indicating a suppression of inflammatory and apoptotic pathways. Additionally, Bcl2 expression was significantly increased, highlighting a shift toward cell survival mechanisms. Conclusion: Our findings demonstrate that PEPITEM exerts a multifaceted therapeutic effect in the EAE model of MS by mitigating the symptoms of EAE as evidenced by modulating crucial biomarkers involved in neuroprotection, inflammation, and apoptosis. The significant alterations in the expression of the biomarkers highlight the potential of PEPITEM as a promising therapeutic agent for MS, offering insights into its mechanism of action and paving the way for future clinical investigations.
Secondary fastener (tape) placement on a blood pressure cuff causes interindividual Doppler blood pressure measurement variability in healthy large-breed dogs
Authors: Principe Martinez Alejandra B. , Cochran Lauren A. , Ishak Anthony M. , Keys Deborah A. , Frederick Steven W.
Published: August 2024

OBJECTIVE

The objective of this study was to compare Doppler blood pressure (DBP) measurements between blood pressure cuffs (BPCs) with and without a secondary fastener (tape) in healthy nonanesthetized large-breed dogs.

ANIMALS

28 healthy dogs.

METHODS

Superficial palmar venous arch DBP measurements with and without tape on the BPC were performed in lateral recumbency with Doppler ultrasound. Each method was performed 6 consecutive times, with the final 5 values averaged. Bland-Altman plots were made and limits of agreement calculated.

RESULTS

The limits of agreement were –40.8 (95% CI, –55.6 to –26.0) to 45.6 (95% CI, 30.8 to 60.4), indicating that the DBP measured with tape would be expected to be between 40.8 mm Hg below and 45.6 mm Hg above that measured without tape 95% of the time. The mean bias estimate was 2.4 mm Hg (SD, 22.0; 95% CI, –6.1 to 11.0; P = .724), indicating that DBP measurements with tape averaged 2.4 mm Hg higher than without tape.

CLINICAL RELEVANCE

Doppler blood pressure measurements obtained with secondary fasteners on the BPCs differed by > 10 mm Hg compared to the BPCs’ standard hook-and-loop fasteners 54% (30 of 56) of the time. Blood pressure cuffs with dysfunctional hook-and-loop fasteners should be replaced due to poor clinical reliability of DBP measurements. However, it is unclear whether Doppler sphygmomanometry is more accurate with the use of traditional Velcro BPC fasteners or with tape BPC fasteners.
The performance of CFRP-strengthened heat-damaged metakaolin-based geopolymer concrete cylinders containing reclaimed asphalt aggregate
Authors: Abadel Aref A.
Published: August 2024

Concrete structures are extremely vulnerable to fire damage, which greatly undermines their structural strength and durability. Recently, there has been a concerted effort to develop sustainable concrete materials. Geopolymer concrete (GPC) is a promising substitute for conventional cement concrete due to its use of recycled materials. However, despite the positive effect it has on the environment, GPC is susceptible to heat, which can cause it to deteriorate over time. In response to this issue, the use of carbon-fiber reinforced polymer (CFRP) has been proposed as a means of strengthening heat-damaged GPC. This study aims to investigate the effectiveness of CFRP-strengthened heat-damaged metakaolin-based GPC made from reclaimed asphalt pavement (RAP) aggregate. Three concrete mixtures were used, in which the conventional aggregate was substituted with RAP aggregate at 0%, 25%, and 50% replacement levels. In addition, the concrete cylinders were tested under ambient conditions and subjected to 300°C. The results indicated that the substitution with 25% RAP aggregate significantly reduced compressive strength by 39.1%, while 50% replacement resulted in a 66.8% decrease compared with the control mixture. The use of CFRP sheets to strengthen heat-damaged GPC specimens was proven to be effective in increasing the resistance of the heated specimens and restoring the compressive strength and confinement energy to their original state before reaching the ultimate failure point. The use of CFRP sheets significantly increased compressive strengths, with increases ranging from 87.7% to 368.8% at 26°C and 58.8% to 153.9% at 300°C, compared with each mixture’s unstrengthened control specimen.
Adaptive Proportional Derivative Control for Magnetic Bearing in Full Maglev Left Ventricular Assist Device
Authors: Tao Wenfei , Chen Chen , Zhang Kejia
Published: August 2024

In this paper, adaptive proportional derivative (APD) parameter control was proposed to solve the problem of high power consumption caused by the unclear mechanism of liquid disturbance during the lifting-up of magnetic bearing in left ventricular assist devices. A mathematical model was derived that describes how the rotor operates in liquid filling. The disturbance caused by the liquid in the lifting-up process was analyzed, and an adaptive control system was developed to improve dynamic performance and reduce power consumption. The experimental results show that APD control requires a shorter rise time without overshoot of rotor displacement compared to traditional fixed configurations. When using the APD controller, the peak current dropped by 8%. The duration in which the current is greater than 1A was reduced by 10.2 ms, and the average current also dropped by 34%.

La información climatológica es importante en la aplicación e investigación en distintas disciplinas relacionadas con los recursos naturales y el medio ambiente, sin embargo su adquisición puede ser difícil y demandar mucho tiempo, particularmente en zonas montañosas (Kouwen et al., 2005). Las estaciones meteorológicas terrestres no siempre representan de modo adecuado el clima que ocurre en las regiones de estudio o cuenca hidrográficas por su falta de cobertura geográfica, además de que presentan vacíos de información en sus series de datos. Ante tal problemática, en el presente trabajo de investigación se evaluaron datos mensuales de precipitación, temperatura máxima y mínima provenientes del conjunto de datos meteorológicos globales denominado “Reanálisis del Sistema de Predicción del Clima” (CFSR, por sus siglas en inglés), como una fuente de información de uso alternativo frente a las observadas in situ en estaciones convencionales (CLICOM), mediante un análisis estadístico en la cuenca alta del río Mayo, Chihuahua, México. Los indicadores estadísticos que se emplearon (sesgo porcentual, raíz del error cuadrático medio, error promedio absoluto y coeficiente de determinación) mostraron que, en general, existe un buen desempeño del CFSR en el modelamiento de la precipitación, temperatura máxima y mínima en época seca, y una sobreestimación durante los meses de lluvia.

Existen numerosas tipologías para su control, desde estructuras discontinuas, como espigones de variados tipos, y continuas, como enrocados, gaviones y colchonetas. En este trabajo se describe una configuración de manta articulada flexible y superponible para el control de la erosión hidráulica. Se presentan los ensayos experimentales para evaluar rugosidad, comportamiento hidráulico y estabilidad al inicio de movimiento de la misma, demostrando su efectividad frente a alternativas como enrocados. Los resultados muestran que una manta de bloques constitutivos (de densidad ⍴ = 1.92 kg/m3 y altura igual a 1 cm) con sus respectivos conectores flexibles se comporta igual a un lecho de sedimentos (⍴ = 1.65 kg/m3) de diámetro característico igual a 2 cm, en lo que respecta a su rugosidad y a su condición de iniciación al movimiento. Esto permite concluir que las protecciones flexibles desarrolladas para el control de la erosión presentan una alta efectividad, buen desempeño y menores volúmenes y costos asociados.

The main objective of this research paper is to analyses the reasons for bottled water consumption in Mexico and consumer perceptions. It was conducted a systematic literature review using the Preferred Reporting Item for Systematic Reviews (PRISMA) and the STROBE Checklist. The study design was chosen because it involves the utilization of explicit and reproducible methods for searching, appraising and synthesizing information on the topic. Electronic searches were conducted via Web of Science and Scopus, with articles published between 1987 and 2022 being identified. The articles were then screened for relevance, applicability, validity, and reliability. The data extraction process involved the use of the Systematic Review Data Repository (SRDR). The tool is web-based and seminal in the extraction and management of data for systematic review. A total of 26 articles were identified which offered a historical review of bottled water consumption in Mexico. The articles cite that the spike in demand for bottled water is caused by organoleptic and health perceptions among the customers. The perceptions are traced back to the 1985 earthquake and cholera outbreak in 1991, which caused water scarcity and contamination issues. The research is novel, with a review of the articles showing there is an apparent dearth of knowledge with regards to the main reason why Mexico is the number one consumer of bottled water. The information presented is seminal in helping public administrators improve water supply service quality and customer satisfaction rates.

Subject. This article analyzes various accounting methods and approaches to cost accounting at the Research, Development, Test, and Evaluation (RDT&E) stage based on IFRS, aimed at reducing losses of the current period and improving the efficiency and financial stability of science-driven and high-tech international projects.
Objectives. The article aims to develop an algorithm for accounting for capitalized costs in the correspondence of accounts and its visualization in the flowchart format.
Methods. The research is based on the basic principles of the theory of firm, the International Financial Reporting Standards (IFRS), Russian Accounting Standards, the Tax Code of the Russian Federation, and the theory of fundamental value of assets.
Results. The article proposes a procedure for accounting for capitalization of costs at the R&D stage based on IFRS, aimed at improving the financial stability of the project and its net present value.
Conclusions. The method of cost capitalization at the RDT&E stage is an effective accounting tool for managing the value and financial stability of the project. Applying the cost capitalization method at the RDT&E stage causes an increase in the net present value of the project and the market value of the company during the period of mass production due to discounting and redistribution of deferred income taxes over time. Applying the cost capitalization method causes a certain decrease in turnover and the return on assets, however, as soon as the production got the stationary mode and the average industry values of the return on equity are reached, this does not significantly affect the project performance indicators.
