Published: December 2023

The occurrence of landslides in reservoir areas and the potential secondary disasters near dams are characterized by their sudden and catastrophic nature, often limiting the availability of actual measurement data. To address this challenge, prototype physical model test always proves to be valuable method to replicate or reproduce such geological hazards. In this study, we focused on the Meilishi landslide in the Gushui reservoir area as a case study to analyze the potential threat of high landslide-induced waves under gravity. Based on field investigations and relevant statistical geological data, a large-scale three-dimensional physical model was carried out that integrated the interactions of the landslide, the river, and the dam. With a scale of 1:150, the model had the dimensions of 57, 27, and 8m. Water level and the maximum sliding velocity into the water were selected as independent variables, leading to a total of 18 experiments. An adaptive landslide motion simulation system based on velocity equivalence and a comprehensive measurement system with tracking technology based on hydrodynamics were independently developed. Those approaches allowed us to reveal the propagation characteristics and attenuation laws of high landslide-induced waves in a curved channel under various complex conditions. The data showed that the maximum wave run-up height on damwas 17.97 m under the most dangerous working condition (H3C09). Importantly, this value did not exceed the maximum height of dam, indicating a certain level of safety margin for the dam. Combined with the data of different working conditions, the optimal window for landslide risk prevention and control warnings was within 550 s after the onset of landslide instability. The key parameters predicted by the tests, including head wave height, wave run-up height on the opposite bank, wave run-up height on dam, and the propagation times, provided a technical basis and valuable reference for dam engineering design and safety. These results make significant contributions to the prevention and control of similar surges hazard induced by high landslides around the world.

Authors: Roy Ishita , Roy Nilanjan
Published: December 2023

We present the case of a 28-year-old male with a history of alcohol dependency and smoking, who presented with chest pain, shortness of breath, and altered sensorium. He exhibited severe metabolic acidosis, low platelet count, and acute kidney injury. Alcoholic ketoacidosis (AKA) was suspected due to ketonuria, metabolic acidosis, and ketonemia, compounded by electrolyte abnormalities and radiographic findings of pneumonia.
Prompt intervention included electrolyte correction, thiamine supplementation, broad-spectrum antibiotics, and diuretics. Thiamine played a pivotal role in the patient's recovery, with significant improvement in consciousness observed within a day. After six days, the patient was discharged in stable condition, showing normal renal and hepatic function during follow-up.
This case emphasizes the need for early recognition and comprehensive management in AKA, highlighting thiamine's crucial role in treatment success.
The Impact of Renewable and Non-Renewable Energy Consumption on Aggregate Output in Pakistan: Robust Evidence from the RALS Cointegration Test
Authors: Khalid Waqar
Published: December 2023

Pakistan’s energy consumption has significantly increased over the past three decades due to industrialization, population growth, and development activities. Pakistan has initiated short-term energy-oriented plans by establishing thermal power projects to meet the growing energy demands. However, these projects are more costly in terms of financial outlays and environmental harms than hydropower projects. Consequently, Pakistan is vulnerable to global oil price fluctuations and environmental damage. To address this dilemma, this empirical research examines the impact of non-energy factors (labour and capital) and energy-specific factors (renewable and non-renewable) on Pakistan’s aggregate output by considering annual data from 1980 to 2021. The analysis employs the newly established Residual Augmented Least Square (RALS) cointegration test and the Autoregressive Distributed Lag (ARDL) methodology to estimate the long-term cointegrating connection among the variables. The empirical findings demonstrate that non-energy and energy-specific factors positively and significantly impact Pakistan’s long-term aggregate output, except for petroleum consumption (insignificant). The study suggests a diversified energy-supply mix explicitly characterized by hydroelectricity, non-hydroelectric renewables (mainly solar and wind), and natural gas. Furthermore, the study suggests encouraging private sector participation in renewable energy initiatives and implementing effective carbon tax policies to mitigate CO2emissions and improve economic growth.

Authors: Zvizdic Zlatan , Jonuzi Asmir , Glamoclija Una , Vranic Semir
Published: December 2023

Objectives
Finding a reliable preoperative predictor of complicated acute appendicitis (AA) has been a challenging diagnostic problem. The present study aimed to identify potential factors that may predict complicated AA in the pediatric emergency department (ED) based on routine, widely available laboratory tests on admission to the ED, including plasma sodium concentration.
Methods
We retrospectively reviewed clinical and laboratory data of pediatric patients with AA who underwent emergency surgery at our department between January 2020 and December 2022. The patients were divided into two groups: histopathologically proven complicated (n = 80), and non-complicated AA (n = 155).
Results
Complicated AA was associated with reduced plasma sodium and chloride concentrations (p < 0.001, both), decreased values of lymphocytes (p = 0.002), elevated C-reactive protein (CRP) (p < 0.001), elevated values of white blood cells (WBC) and neutrophils (p = 0.012 and 0.001, respectively). In binomial logistic regression, increased CRP, WBC, and decreased sodium levels were predictors of complicated AA. The area under the ROC curve was 0.825 (95% CI 0.764, 0.886).
Conclusion
We identified mild hyponatremia and elevated CRP and WBC values as potential markers for distinguishing complicated from uncomplicated pediatric AA with implications for treatment approach, either surgical in complicated or conservative in uncomplicated disease.
Impact of human resource characteristics of internal accounting system on post-earnings announcement drift: Evidence from Korea
Authors: Ryu Haeyoung , Chae Soo-Joon
Published: December 2023

When companies invest in their internal accounting personnel, investors place greater trust in disclosed earnings information and highly regard a company’s information transparency. This results in prompt investment decisions regarding the company. Consequently, earnings information will be immediately reflected in stock prices, thereby reducing stock price drift. The purpose of this study is to examine the impact of investments in establishing and operating internal accounting systems on investors’ responses to the mitigation of stock price drift. The study focused on firms listed on the Korea Exchange from 2011 to 2018 and constructed a regression model using the cumulative abnormal return following earnings disclosure dates for 30, 60, and 120 days as the dependent variable, with the characteristics of internal accounting personnel as independent variables. The analysis reveals that companies with many internal accounting personnel and position experts, such as accountants, within their internal accounting control systems, experience a significantly lower stock price drift. The coefficients of the interaction terms between internal accounting personnel characteristics and standardized unexpected earnings are positive and significant at the 1% level for all cumulative abnormal return values. The findings of the study indicate that as efficiency is secured, stemming from the scale of personnel managing internal accounting control systems and their expertise, market investors’ understanding and trust of accounting information also increase. Investors, as information users, react promptly to the earnings information disclosed by the company, leading to a decrease in stock price drift.

Current status of transcatheter intervention for complex right ventricular outflow tract abnormalities
Authors: Kagiyama Yoshiyuki , Kenny Damien , Hijazi Ziyad
Published: December 2023

Various transcatheter interventions for the right ventricular outflow tract (RVOT) have been introduced and developed in recent decades. Transcatheter pulmonary valve perforation was first introduced in the 1990s. Radiofrequency wire perforation has been the approach of choice for membranous pulmonary atresia in newborns, with high success rates, although complication rates remain relatively common. Stenting of the RVOT is a novel palliative treatment that may improve hemodynamics in neonatal patients with reduced pulmonary blood flow and RVOT obstruction. Whether this option is superior to other surgical palliative strategies or early primary repair of tetralogy of Fallot remains unclear. Transcatheter pulmonary valve replacement has been one of the biggest innovations in the last two decades. With the success of the Melody and SAPIEN valves, this technique has evolved into the gold standard therapy for RVOT abnormalities with excellent procedural safety and efficacy. Challenges remain in managing the wide heterogeneity of postoperative lesions seen in RVOT, and various technical modifications, such as pre-stenting, valve ring modification, or development of self-expanding systems, have been made. Recent large studies have revealed outcomes comparable to those of surgery, with less morbidity. Further experience and multicenter studies and registries to compare the outcomes of various strategies are necessary, with the ultimate goal of a single-step, minimally invasive approach offering the best longer-term anatomical and physiological results.

Authors: Ahmadzadeh Masoumeh , Rahimi Mehran , Toufan-Tabrizi Mehrnoush , Mohammadi Kamran
Published: December 2023

Objectives: Accurate assessment of left ventricular (LV) function is essential for managing patients with left bundle branch block (LBBB). This study aimed to evaluate the relationship between LV systolic function, left ventricular diastolic filling time (LVFT), QRS duration, and heart failure symptoms in patients with LBBB.
Methods: This study was conducted between June 2021 and June 2022. Patients with LBBB and sinus rhythm who were referred to the echocardiography department were included in the study. All the patients underwent electrocardiogram-gated echocardiography using the same machine. In this study, the LVFT value was measured in absolute terms and as a ratio to the R-R interval (LVFT/RR).
Results: A total of sixty-five patients were included, forty-two (64.6%) were women, and the mean age was 60.71 ± 8.72. We performed three one-way ANOVA tests that showed that LV filling time/RR ratio, QRS duration, and ejection fraction were significantly different between heart failure classes (p=0.008, p=0.001, and p<0.001, respectively). A weak correlation was observed between LVEF and LVFT/RR (r= 0.349, p=0.004). Additionally, QRS duration was negatively correlated with LVEF (r = -0.395, p=0.004) and LVFT/RR (r = -0.350, p=0.004), although these correlations were weak.
Conclusion: We showed that LVFT/RR ratio differed significantly between HF functional classes and was lower in patients with more severe HF symptoms. Additionally, QRS duration was negatively correlated with LVEF and LVFT/RR, and patients with more severe HF symptoms had longer QRS durations.
Metabolic modelling of microalgae for wastewater treatment
Authors: Pessi B. Assis
Published: December 2023

Wastewater treatment using microalgae presents a promising approach for sustainable and efficient removal of pollutants. However, the complexity of metabolic networks involved in microalgae metabolism poses challenges for computational analysis. This chapter explores network reduction methods, specifically focusing on the application of the DRUM (dynamic reduction of unbalanced metabolism) framework, to streamline the modelling of microalgae-based wastewater treatment systems. This chapter describes the general core metabolism of microalgae, reviews methods of metabolic network reduction, and ends it with the application of a case study. The DRUM framework divides the complete metabolic network into subnetworks where the quasi-steady-state assumption (QSSA) holds, reducing the number of state variables and simplifying the kinetic modelling. By calculating the elementary flux modes (EFMs) for each subnetwork, macroscopic reactions are derived, representing the collective behaviour of internal reactions within the subnetworks. To demonstrate the effectiveness of the DRUM framework, a case study based on Chlorella sp. microalgae is presented. The study focuses on treating volatile fatty acid waste, a common byproduct of dark fermentation. The reduced metabolic model, obtained using the DRUM framework, accurately captures the dynamics of microalgae growth and medium concentration. This chapter underscores the significance of network reduction methods in optimizing microalgae-based wastewater treatment systems. These reduction methods pave the way for further advancements in the development and optimization of microalgae-based wastewater treatment technologies.
Production of biopolymers from microalgae and cyanobacteria
Authors: Sakarika M. , Sventzouri E. , Pispas K. , Ali S. S. , Kornaros M.
Published: December 2023

Over the past few decades, plastic-derived pollution has been recognized as a major environmental issue because the use of conventional plastics results in vast amounts of waste as well as in fossil-fuel depletion. Biodegradable and biobased polymers are a promising alternative to conventional plastics. In this context, polyhydroxyalkanoates (PHAs) are bioplastics with similar mechanical and thermal properties to petroleum-based plastics which can be used in a wide range of applications. Several studies have reported the accumulation of PHAs in the biomass of microalgae and cyanobacteria. Under optimal conditions for PHA accumulation, that is, nutrient limitation, and optimal light intensity, PHA content can significantly increase, achieving 85% of dry biomass weight. Downstream recovery of PHAs is also a critical step that affects the properties and the yield of PHAs. Bioplastic production from microalgae and cyanobacteria on a commercial scale is still limited due to its high cost, with the cultivation medium accounting for up to 50% of the total production cost. The use of wastewater as a growth medium can improve the economic feasibility and sustainability of PHA production from microalgae and cyanobacteria and contribute to a more circular economy.
Current Insight into Novel Delivery Approaches of Resveratrol for Improving
Therapeutic Efficacy and Bioavailability with its Clinical Updates
Authors: Harwansh Ranjit K. , Yadav Paras , Deshmukh Rohitas
Published: December 2023

Resveratrol (RSV) is a polyphenolic phytoalexin, and belongs to the stilbene family. RSV has several
therapeutic activities such as cardioprotective, anticancer, and antioxidant. Apart from its therapeutic benefits,
its pharmacological uses are limited due to low solubility, poor bioavailability, and short biological halflife.
A researcher continuously focuses on overcoming the limitations of RSV through nanotechnology platforms
to get the optimum health benefits. In this context, nanocarriers are pioneering to overcome these drawbacks.
Nanocarriers possess high drug loading capacity, thermal stability, low production cost, longer shelflife,
etc. Fortunately, scientists were proficient in delivering resveratrol-based nanocarriers in the present scenario.
Nanocarriers can deliver drugs to the target sites without compromising the bioavailability. Thus, this review
highlights how the latest nanocarrier systems overcome the shortcomings of RSV, which will be good
for improving therapeutic efficacy and bioavailability. Moreover, recent updates on resveratrol-based novel
formulations and their clinical trials have been addressed to manage several health-related problems.
Modulation of Caco-2 Colon Cancer Cell Viability and CYP2W1 Gene Expression by
Hesperidin-treated Lacticaseibacillus rhamnosus GG (LGG) Cell-free Supernatants
Authors: Akkulak Merve , Evin Emre , Durukan Ozlem , Celebioglu Hasan Ufuk , Adali Orhan
Published: December 2023

Background and Objective:

Ensuring colon homeostasis is of significant influence on colon cancer
and delicate balance is maintained by a healthy human gut microbiota. Probiotics can modulate the diversity of
the gut microbiome and prevent colon cancer. Metabolites/byproducts generated by microbial metabolism significantly
impact the healthy colonic environment. Hesperidin is a polyphenolic plant compound well known for its
anticancer properties. However, low bioavailability of hesperidin after digestion impedes its effectiveness.
CYP2W1 is a newly discovered oncofetal gene with an unknown function. CYP2W1 gene expression peaks
during embryonic development and is suddenly silenced immediately after birth. Only in the case of some types
of cancer, particularly colorectal and hepatocellular carcinomas, this gene is reactivated and its expression is
correlated with the severity of the disease. This study aimed to investigate the effects of hesperidin-treated Lacticaseibacillus
rhamnosus GG (LGG) cell-free supernatants on CaCo2 colon cancer cell viability and CYP2W1
gene expression.

Methods:

Alamar Blue cell viability assay was used to investigate the cytotoxic effect of cell-free supernatant of
LGG grown in the presence of hesperidin on CaCo2 cells. To observe the effect of cell-free supernatants of LGG
on the expression of CYP2W1 gene, qRT-PCR was performed.

Results:

Five times diluted hesperidin treated cell-free supernatant (CFS) concentration considerably reduced
CaCo2 colon cancer cell viability. Furthermore, CYP2W1 gene expression was similarly reduced following CFS
treatments and nearly silenced under probiotic bacteria CFS treatment.

Conclusion:

The CYP2W1 gene expression was strongly reduced by cell-free supernatants derived from LGG
culture, with or without hesperidin. This suggests that the suppression may be due to bacterial byproducts rather
than hesperidin. Therefore, the CYP2W1 gene in the case of deregulation of these metabolites may cause
CYP2W1-related colon cancer cell proliferation.
Modeling and Analysis of Cancer Electrothermic Therapy Technique based on a Digital Arm
Authors: Xu Jing , Zhang Man , Kuang Jiangming , Qin Yuping , Zhang Shuang
Published: December 2023

Background:

Intramuscular hemangioma (IMH) is a diffuse growth hemangioma located
in the striated muscle, which is often overlooked due to its rarity.

Objective:

This patent pertains to the integration of electroacupuncture with electrothermotherapy.
By introducing electrical signals into the electroacupuncture system, electromagnetic heat is produced.
This heat leads to the electrolysis and thermal destruction of tumor cells, enabling targeted
and precise cancer treatment. Furthermore, the patent offers a theoretical foundation for exploring
the distribution of electrical signals and the associated heat in arm muscles, ensuring accurate
treatment.

Material and Method:

To enable subsequent experimental validation, this patent integrates human
anatomy and histological structure theory. The arm's geometric structure was derived from
segmentation, reconstruction, and substantiation based on a digital human image dataset. Using
the COMSOL Multiphysics 5.5 software, a semi-detailed finite element model was developed for
the numerical simulation of electrothermotherapy. Within a time domain setting, a carrier signal
of 1 MHz and 22 V was introduced to assess the distribution of electrical signals and the associated
heat in the arm muscle.

Results:

Electrical signals, electromagnetic heat, and tissue necrosis primarily concentrate in a
spherical region within 10 mm of the exposed electroacupuncture tip, with the maximum coupling
temperature reaching 250 °C at the tip. Time domain analysis revealed that the coupling temperature
can rise within 1 min, sufficiently to cause complete tissue damage, with the tissue necrosis
ratio reaching 100% in the same timeframe. While the coupling temperature continues to rise over
time, the increment is modest. After 5 min, there is negligible temperature change, and once the
tissue necrosis ratio reaches 100%, it remains consistent.

Conclusion:

In the precision tumor treatment system utilizing electrothermotherapy, factors, such
as the magnitude of the injected electrical signal, placement of the electroacupuncture tip, and
treatment duration play a crucial role in the treatment's accuracy. This model delves into the
treatment of intramuscular hemangiomas using electroacupuncture electrothermotherapy from two
perspectives: spatial and temporal domains. It provides a theoretical foundation for precise electrothermotherapy
in cancer treatment.

Authors: Fawaz Walaa , Hasian Jameela , Alghoraibi Ibrahim
Published: December 2023

Background:

Vincristine sulfate is commonly used to treat different types of cancers. However,
its effectiveness is hindered by undesirable side effects, which significantly limit its applications
in medicine.

Objective:

This study aims to prepare vincristine nanoparticles, in order to develop a promising approach
for cancer therapy.

Methods:

Vincristine nanoparticles were prepared by utilizing polycaprolactone as a carrier through
the double emulsion method. The morphological characteristics and particle size of the vincristine nanoparticles
were examined. The surface charge and average dynamic size, encapsulation efficiency in
addition to release profile study were also evaluated.

Results:

Dynamic Light Scattering confirmed the small size of nanoparticles (~200 nm). SEM showed
spherical-shaped nanoparticles with smooth surfaces, and the polydispersity index values of the prepared
nanoparticles were below 0.5 in all preparations. The zeta potential of the nanoparticles was
found to be negative, which can be attributed to the presence of carboxylic groups in the PCL polymer,
The encapsulation efficiency of Vincristine-loaded nanoparticles (NPs) varied from 36% to 57% for all
the prepared NPs with varying amounts of PCL. The release profile demonstrated a prolonged release
of Vincristine from the nanoparticles compared to the Vincristine solution.

Conclusion:

The double emulsion solvent evaporation method was used successfully to prepare vincristine-
loaded PCL nanoparticles, which suggests that nanoscale carriers hold promise as effective
vehicles for delivering chemotherapeutic agents in the treatment of cancer.

Microwave-assisted synthesis is a powerful tool in organic chemistry, providing a rapid and efficient method for the synthesis of bioactive heterocycles. The application of micro-waves significantly reduces reaction times and increases percentage yields with high purity of the final product. To make the synthetic protocol greener, the application of the magnetic nanocata-lyst is a rapidly growing area of interest nowadays. Magnetic nanocatalyst, with its unique fea-tures like magnetic separable facile recovery from the reaction media heterogeneously, makes the overall synthetic strategy cleaner, faster, and cost-effective. Aiming this, in the present review, we will focus on the infusion of Magnetic nanocatalyst to microwave-assisted synthesis of vari-ous classes of azaheterocyclic compounds, including pyridines, pyrimidines, quinolines, and ben-zimidazoles. The synthetic methodologies involved in the preparation of these heterocycles are highlighted, along with their biological activities. Furthermore, in this review, the most recent and advanced strategies to incorporate nanocatalysts in the microwave-assisted synthesis of nat-ural products containing azaheterocyclic moieties in drug discovery programs are elucidated in detail, along with the incoming future scope and challenges.
Manganese Doped Topological Insulators
Authors: Yasin M.W.
Published: December 2023

When a topological insulator is incorporated with magnetism, the time-reversal symmetry (TRS) breaks. This chapter sums up the current research in Mn-doped topological insulators, mostly focusing on antiferromagnetic MnBi2Te4 and its family. Specific critical behavior of Mn-doped Bi2Te3 topological insulator reveals ferromagnetic ordering (to increase conductivity) of Mn spin at normal substitution. Moreover, due to intrinsic anti-state substitutional defect if a comparable amount of local moment is produced then calculated data is in favor of a spin glass state with polarization. Exotic phenomena like the magnetoelectric effect and dissipation less edge state occur in this material and to study MnBi2Se4 epitaxial thin films a scanning tunneling microscope (STM) is utilized. Steps between a screw dislocation and the van der Waals layer are manifested in the large-scale topographic image. In a small area at the edge Bi termination is occurred and Se termination is dominant at the surface, this termination is compared by examining step height, tunneling spectroscopy, and resolution image. Similarly, for analyzing Mn impurity in Bi2Se3 electron paramagnetic resonance is used and by implementing the vertical Bridgman method topological insulator is grown. Mn2+ configuration was found in conducting state of a host metal and Mn in high spin =5/2Mn^(2+). This assumption shows that energy level Mn^(2+) (d^5) is present the valence bad (VB) and energy level, Mn^(1+) (d^6) is located far way form energy gap.
Topological Insulators in Optical Applications

Published: December 2023

Since the discovery of topological insulators, researchers in condensed matter physics have focused on studying multiple topological states of matter. Topological insulators can transport an electron across the boundary without backscattering when they experience surface contaminants because of the unique exotic phase they exhibit. Research in topological photonics is among the most active fields of study in optics, and it is also one of the driving forces of research in topological physics. With the recent discovery of topological states of matter, EM waves can now be controlled and manipulated in a novel way. These metamaterials have the ability to revolutionize a wide range of electromagnetic design domains, from very durable cavities to tiny waveguides.

La Lógica Capitalista y la Vivienda
Authors: Sánchez Arrastio Rogelio Moisés
Published: December 2023

En este trabajo analizaremos el porqué de la migración del capital hacia diferentes actividades productivas, buscando la rentabilidad del capital. Iniciaremos con la visión ya Clásica de Marx (1976), ya que parte de la necesidad de valorizar el capital y las consecuencias de esta búsqueda. La migración de capitales de un sector a otro, buscando una mejor cuota de plusvalía, dinámica que incluye al sector constructor de vivienda, concluyendo que en esta migración intervienen además de la rentabilidad, el rompimiento y construcción de nuevos imaginarios, sobre todo en los sectores ligados al recurso llamado tierra; pero no nos quedamos con la visión de un tránsito de los capitales de un sector a otro sin ningún contratiempo, pues esto está muy distante en economías como la nuestra, por eso consideramos necesario abordar el planteamiento desde la perspectiva de la existencia de una estructura de mercado oligopólico, para ello recurrimos al trabajo desarrollado por Kalecki (1984,1995).

Cabbage plants (Brassica oleracea) belong to the Brassicaceae family, is a vegetable that is widely cultivated by farmers in rural Indonesia. In an effort to increase the productivity of purple cabbage it is necessary to carry out soil management. Andisol is one type of soil that is relatively fertile but has a high level of P absorption so it is necessary to add Chicken Manure and TSP Fertilizer. The purpose of this study is to determine the effect of treatment and response from the combination of treatment on the application of chicken manure and TSP fertilizer on the growth and production of purple cabbage plants.  The research design used was a group randomized design (RAK) with 2 factors arranged factorially. The first factor is chicken manure fertilizer which consists of 3 levels, namely: K1 = chicken manure fertilizer 10 tons / ha (50 grams / polybag), K2 = chicken manure fertilizer 20 tons / ha ( 100 grams / polybag) and, K3 = chicken manure fertilizer 30 tons / ha ( 150 grams / polybag). The second factor of TSP fertilizer consists of 3 levels, namely: T1 = TSP 200 kg / ha ( 1 gram / polybag), T2 = TSP 300 kg / ha ( 1.5 grams / polybag) and, T3 = TSP 400 kg / ha ( 2 grams / polybag).  Treatment of Chicken Manure (K), TSP fertilizer, and Interaction (KxT) had no real effect (P ≥0.05) on the variables of maximum plant height, maxmium leaf count, root length, flower crop diameter and wet weight of crop per plant.

The The research aims to determine the effect of gross domestic product (GDP) and inflation on the total money supply (JUB) in Indonesia. This study uses timeseries data from 1980 to 2020 obtained from the Central Bureau of Statistics, and Bank Indonesia. This study uses a classical approach. The research was conducted using multiple linear regression. Hypothesis testing using the t test and f test is used to determine the feasibility of the model. The results of the analysis show that the Gross Domestic Product Variable (X1) partially has a positive and significant effect on the Money Supply in Indonesia. The Inflation Variable (X2) partially influences the Money Supply in Indonesia. Based on the analysis of the Simultaneous Test value prob. F of 0.00 < error rate of 0.05. Thus, Ho is rejected and H1 is accepted. This shows that the Gross Domestic Product (X1) Inflation (X2), simultaneously has a significant effect on the Money Supply in Indonesia, because F count is 36.07 > 3.25 F table and the Adjusted R Square coefficient or the coefficient of determination is 0.7452 This means 74.52% of the variation or change in the total money supply can be explained by variations in Gross Domestic Product and Inflation, while the rest (25.48%) is explained by other variables outside this research model. This is consistent with the quantity theory of money. According to the quantity theory of money, according to Irving Fisher, it states that the amount in circulation is directly proportional to changes in prices.
