Authors: Budiman Gondowardojo Yustinus Robby , Ompusunggu Sevline Estethia , Dahlan Rully Hanafi
Published: August 2022

Background:

Almost 60% of all spinal tumors are spinal intradural extramedullary (IDEM) neoplasms. The most common symptoms of these tumors are pain and neurological deficits. Until recently, the treatment of choice is still tumor resection microsurgically. The study aims to present of diagnosis and management of IDEM in Hasan Sadikin Hospital, Bandung, Indonesia, and to outline the current diagnosis and management of IDEM tumors commonly performed.

Methods:

This study was a retrospective descriptive study using medical records to identify and describe cases of IDEM tumors in Hasan Sadikin Hospital. A total of seven IDEM tumor cases from January 2019 to April 2021 were identified. Data collected included demographics, diagnosis, and management.

Results:

Most cases of IDEM tumors in our study were seen in women >40 years of age (n = 5). The age range of patients at diagnosis is between 25 and 68 years. The management carried out is tumor resection through laminectomy with (n = 5) or without (n = 2) posterior stabilization.

Conclusion:

The proper diagnosis and treatment are required in improving a patient’s life quality. Magnetic resonance imaging is the gold standard for radiological examination, and for management of choice is gross-total removal of the tumor.
Soap and Water to Hands and Face, -Eye Rinse, Nasal Irrigation and Gargling with Saline for COVID-19 with anecdotal evidence
Authors: Parviz S. , Duncan L. , Rabago D.
Published: August 2022

This paper provides a brief historical background of saline nasal irrigation (SNI), main modes of SARS-COV-2 transmission and entry, and anti-infective properties of saline. It reviews the protective evidence associated with SNI and gargling against viral upper respiratory tract infection (URTI). SARS-CoV-2 presents as an URTI transmitted mainly via respiratory droplets and aerosols to the oro-nasal mucosa and indirectly after touching these entry sites from contaminated fomites. It can potentially be transmitted from the conjunctival mucosa to the nasal mucosa or from resuspension and inhalation from the facial area around the nose. SNI has antiviral, anti-inflammatory and mucociliary restorative properties. Numerous randomized controlled trials have reported that SNI, with and without gargling, prevents and treats viral URTI. Based on biological rationale and anecdotal evidence we suggest a protocol: Soap and Water to the Hands and Face-Eye Rinse Nasal Irrigation and Gargling with Saline (SWHF-ERNIGS) may limit the transmission SARS-CoV-2, and prevent and treat COVID-19 infection. Clinical considerations of the protocol are presented. The protocol is safe, straightforward and can be easily performed by healthcare workers and the general public; it uses readily available salt, water and soap. Formal studies of effectiveness and application of the protocol are warranted.

Published: August 2022

Ovophis makazayazaya bite is an uncommon cause of snakebite that humans may sustain as a result of the continuous overexploitation of forest habitats and excessive development in Taiwan. Although the Taiwanese government has produced four antivenoms against medically important snakebite accidents, O. makazayazaya is not among the snakes for which an antivenom has been produced. A case of O. makazayazaya snakebite on a patient’s right foot, which later swelled into the hip, is reported. In vitro studies have reported that monovalent antivenoms for Gloydius brevicaudus and Trimeresurus albolabris, and polyvalent antivenom for Calloselasma rhodostoma, Daboia siamensis, and T. albolabris show reactivity toward Ovophis venoms. However, these antivenoms are unavailable in Taiwan. Thus, bivalent antivenom for Trimeresurus stejnegeri stejnegeri and Protobothrops mucrosquamatus was used, assuming similar immunoreactivity and a possible para-specific effect of green pit viper antivenom against this Ovophis venom. A favorable outcome was observed, without significant extension in prothrombin time and activated partial thromboplastin time. In addition, no systemic bleeding occurred. Nonetheless, further venom and antivenom evaluations should ascertain the efficacy of this para-specific antivenoms against this crotaline snakebite.

Loa loa is a filarial nematode responsible for loiasis, endemic to West–Central Africa south of the Sahara and transmitted by flies. This study reports a case of L. loa in the vitreous cavity of the eye of a young patient, along with an in-depth literature review. A 22-year-old woman from Cameroon who migrated from Cameroon to Italy was referred to the Emergency Ophthalmology Department at Policlinico di Bari in July 2021 with the presence of a moving parasite in the subconjunctiva of the left eye. A recent onset of a papular lesion on the dorsal surface of the right wrist and a nodular lesion in the scapular region were detected. L. loa filariasis was diagnosed based on anamnestic data, clinical and paraclinical signs, and a parasitological test confirming the presence of microfilariae in two blood samples collected in the morning of two different days. Because of the unavailability of diethylcarbamazine (DEC), albendazole (ALB) 200 mg twice daily was administered for 21 days. A mild exacerbation of pruritus occurred during treatment, but resolved with the use of an antihistamine. A single dose of 12 mg ivermectin was prescribed at the end of the treatment with albendazole. Unlike other endemic parasite infections, L. loa is not included in the Global Program to Eliminate Lymphatic Filariasis, because it is not mentioned in the WHO and CDC list of neglected tropical diseases. This can result in an overall risk of lack of attention and studies on loiasis, with lack of data on global burden of the disease.

The rising demand for cleaner energy among the nations has turned the focus from fossil fuel-based energy sources to renewables like biomass, solar, wind, etc. Biomass conversion to fuel has increased research in recent times due to its ease and availability throughout the year. Hydrothermal liquefaction is the process where biomass converts to a liquid product via complex reaction mechanisms. This review aims to summarize the hydrothermal liquefaction of algal biomass and the improvements in the bio-crude yield using heterogeneous and homogenous catalysts. Many references have been reviewed to provide the sources for the process and have been critically well structured. This review also provided information regarding the reaction pathway for algal biomass and the effects of process parameters like temperature, residence time, pH, etc. The focus of the review is on the effects of various catalysts based on their dosage whose results collected from various sources have been tabulated. The review briefly discusses the applications of products formed during hydrothermal liquefaction after post-processing.

IMPACT OF INVASIVE PLANT SPECIES ON ECOSYSTEMS, BIODIVERSITY LOSS AND THEIR POTENTIAL INDUSTRIAL APPLICATIONS
Authors: Cocîrlea Maria Denisa , Oancea Simona
Published: August 2022

Invasive plant species may cause not only several health problems, but also economic and environmental negative impacts – a gradual decrease of biodiversity and decline of soil fertility, issues that have recently come into the attention of several organizations including the research ones, in order to limit the spread of such species. The control methods of invasive species are often effective on the short term and include the probability of ecosystem imbalance over time, so that an efficient and sustainable management method that could add value to products or improve some industrial processes are strongly required. This study describes the potential of alien plants to maintain the quality of human life through different types of valorization, such as pharmaceutical, agriculture or food industry applications, energy production, paper technology and natural dyeing of various materials. Invasive plant species represent a global problem, accelerated by the current level of pollution and the rapidly-evolving society. Knowledge of chemical composition of different plant parts of invasive species, their potential for developing new products and their health effects will contribute to an efficient control, mechanical, chemical or biological, and an integrated management.

Published: August 2022

This study examined the impact of each of the internal control components such as control environment, risk assessment, and control activities on the financial performance of some selected NGOs in Nigeria. The study was anchored on stakeholders’ theory and adopted a descriptive survey research design to describe the relationship between the variables. The population consists of 200 key staff of the 20 purposely selected NGOs in Nigeria. A structured questionnaire was used to collect data from the respondents and the data collected were analysed using the descriptive statistic of mean and standard deviation while a linear regression model was used to test the relationship between the variables. The findings revealed that control environment and risk assessment to some extent influence the financial performance of surveyed NGOs while control activities have a significant effect. The study concluded that each of the internal control components considered in the study has an impact on financial performance. Inadequacy or nonexistence of any will negatively affect the financial performance of an NGO and vice versa. This study recommended that the management of NGOs should create and maintain a strong internal control system since the organisation's financial success is influenced by the strength of the control system. This can be accomplished by establishing standards, processes, and organisational structures that serve as the pivot for internal control throughout the organisation.

Published: August 2022

Numerous studies have examined the effects of the COVID-19 pandemic on women’s mental health and menstrual cycles. However, most of these studies only included outpatients with COVID-19, whereas information on hospitalised women is minimal. ACE 2 is essential for the SAR-CoV2 virus to enter human cells and the human ovary. Since it stimulates steroid secretion, aids in follicle development and oocyte growth, influences ovulation, and maintains the corpus luteum, it stimulates steroid secretion and aids in follicle development and oocyte growth. Hospitalised female COVID-19 patients exhibit menstrual changes and heightened symptoms of mental health disorders. Length of isolation was the most influential factor in overall menstrual changes and mental health in female COVID-19 hospitalised patients. Infection with COVID-19 may affect the menstrual cycle in females. Further prospective research is required to confirm these findings and determine the duration of these menstrual irregularities.

Published: August 2022

Background: Adenotonsillar hypertrophy (ATH) is a very frequently encountered disease in children under the age of 12 years. It may be associated with growth delay in children. Recurrent Adenotonsillitis leads to Adenotonsillar hypertrophy which causes nasal obstruction. It reduces food intake in child due to dysphagia, this further reduces body stamina where child avoids playing outdoor games, social activities etc. These above factors will be evaluated in this study. Therefore, recent studies have integrated disclosing the any relation of adenotonsillar hypertrophy with the growth of children. Aim: To determine whether there is any relation of adenotonsillar hypertrophy with the growth of children. Objective: To assess the relation of adenotonsillar hypertrophy with the growth of children. Method: 154 school going children were taken up for this study. out of 154, 64 children were diagnosed to be with adenotonsillar hypertrophy with the help of complete historyand clinical examination of children i.e. using throat Questionnaire. Result: There is no relation of Adenotonsillar hypertrophy with growth of children. Conclusion: This study concludes that Adenotonsillar hypertrophy are not associated with growth of children.
FACTORS THAT HINDER COMMUNITY-BASED SECONDARY SCHOOLS IN TANZANIA FROM IMPLEMENTING THE CURRICULUM EFFECTIVELY: A CASE STUDY OF TABORA REGION
Authors: Assey Ernest S. , Malingumu Winfrida , Babyegeya Emmanuel
Published: August 2022

Purpose: This study focused on factors that hinder community-based secondary schools in Tanzania from implementing the curriculum effectively.

Methodology: A case study research design was used in this study. The data were gathered through focus group discussions and interviews with 147 people from various educational cadres, including heads of secondary schools, teachers, District Education Officers (DEO), Quality Assurer’s (QA), parents and students.

Findings: Poor reading culture among students, poor teaching and learning environments, a problem with the medium of instruction, poor parental engagement in children's education, teacher shortages, poor managerial skills among school leaders, and a lack of in-service training among teachers are the main factors that hinder effective curriculum implementation community-based secondary schools in Tanzania, according to the findings of the study.

Unique contribution to practice, theory and strategy: The study's findings help educational stakeholders better understand how curriculum implementation is impacted when a school lacks adequate teaching and learning infrastructure, adequate teaching and learning materials, adequate teaching staffs, and adequate funding to support in-service training for teaching staff. The study's conclusions also supported Rogers' Diffusion Theory's main claim, which holds that effective curriculum implementation is a function of the school environment, which ensures effective interaction between teachers and students as well as teaching and learning materials, as opposed to ineffective curriculum implementation if the school environment does not ensure effective interaction.

Recommendations: The study recommended that Tanzania's government should continue with initiatives to increase the number of teachers, revise the policy governing the medium of instruction in schools, improve the teaching and learning environment as well as infrastructures, schools should fully engage parents in decision-making, improve in-service teacher training, and school heads should undergo frequent training on pedagogical leadership skills as a means of ensuring effective curriculum implementation in community-based secondary schools.
Pipeline Modelling for the Lebanese Offshore: Cases in the Oil
and Gas Industry
Authors: Harkouss Rami
Published: August 2022

Lebanon must build a pipeline system to carry the hydrocarbons from offshore to the shore. With no available studies and not much experience in this domain, designing a pipeline system in Lebanon is a topic of great concern. In this research, a prototype sample for the Lebanese offshore pipeline system is designed taking into consideration different parameters such as the drainage area, skin factor, Dietz shape, production interval, and the wellhead pressure. The system carries the gas from block 9 offshore Lebanon to a suitable production platform using different simulation software, mainly PROSPER. Different scenarios are modelled where results showed an optimum flow rate of 322.834MMscf/day and a wellbore pressure of 6460.73psi at 3000psi wellhead pressure. Further studies are encouraged to be carried out to transport the hydrocarbons from the wellheads of block 9 to the Zahrani processing plant via specified hydraulics engineering software.

В роботі представлені результати дослідження вмісту білку в листках ліній ізогенних за генами контролю фотоперіодичної чутливості сої культурної. У якості об’єктів дослідження використовували майже ізогенні лінії сої за генами контролю фотоперіодичної реакції, які відрізняються між собою тільки станом окремих локусів: короткоденні лінії – сорт Clark та L 80-5879 (генотип відповідно – e1E2E3E4e5E7 та Е1е2е3Е4е5Е7); фотоперіодично нейтральні лінії – L 63-3117 та L 71-920 (генотип відповідно – e1е2Е3Е4е5Е7 та e1e2e3E4e5E7). Для бактеризації рослин використовували штам Bradyrhizobium japonicum 634b. Стерилізоване насіння бактеризували Bradyrhizobium japonicum 634b, висаджували у ґрунт та вирощували за природнього довгого дня (16 годин на широті м. Харкова – 50° п.ш) в умовах польового експерименту. Відбирали сформовані 2 та 3 листки під час вегетативної фази V3, V4 та V5. Білок з фіксованого матеріалу екстрагували за допомогою фосфатно-сольового буферу (рН=7,4) та визначали його вміст за Бредфордом. За результатами проведених аналізів виявлено, що бактеризація не впливає на вміст білку у ізоліній L 80-5879 та L 71-920, у той час як за бактеризації у ізолінії L 63-3117 та сорту Clark спостерігається значне підвищення його вмісту. Це може бути пов’язано з наявним домінантним станом гену Е3, який детермінує біосинтез фітохрому А, що є більш чутливим до дії дальнього червоного світла, який його деактивує. Припускаємо, що неактивний стан фітохрому А може призводити до порушення поглинання нітрат-іонів, що в свою чергу може позитивно впливати на розвиток взаємодії рослин сої культурної з диазотрофами, маркером чого є підвищення вмісту білку в листках за умови бактеризації.

Environmental and hydrologic controls on sediment and organic carbon export from a subalpine catchment: insights from a time-series
Authors: Schwab Melissa Sophia , Gies Hannah , Freymond Chantal Valérie , Lupker Maarten , Haghipour Negar , Eglinton Timothy Ian
Published: August 2022

Abstract. Studies engaging in tracking headwater carbon signatures downstream remain sparse, despite their importance for constraining transfer and transformation pathways of organic carbon (OC) and developing regional-scale perspectives on mechanisms influencing the balance between remineralization and carbon export. Based on a 40-month time series, we investigate the dependence of hydrology and seasonality on the discharge of sediment and OC in a small Swiss subalpine watershed (Sihl River basin). We analyze concentrations and isotopic compositions (δ13C, F14C) of particulate OC and use dual-isotope mixing and machine learning frameworks to characterize and estimate source contributions, transport pathways, and export fluxes. The majority of transferred OC is sourced from plant biomass and soil material. Relative proportions of soil-derived particulate OC peak during the summer months, coinciding with maximum soil erosion rates. Bedrock-derived (petrogenic) OC abundant in headwater streams progressively decreases downstream in response to a lack of source material and efficient overprinting with biospheric organic matter, illustrating rapid OC transformation over short distances. Large variations in isotopic compositions observed during baseflow conditions converge and form a homogenous mixture enriched in OC and characterized by higher POC- F14C values following precipitation-driven events. We propose that storms facilitate surface runoff and shallow landsliding, resulting in the entrainment of fresh litter and surficial soil layers. Model results further indicate diverging mobilization pathways. Discharge and water stage describe the export of suspended sediment, while the prediction of POC fluxes is mostly supported by water stage and 1-day antecedent precipitation. Although particle transport in the Sihl River basin is mainly driven by hydrology, subtle changes in bedrock erosivity, slope angle, and floodplain extent likely have profound effects on the POC composition, age, and export yields.
The Permian-Triassic transition in the Blue Nile Basin: insights from petrography and geochemistry of sandstones
Authors: Mansouri Maryam , Stutenbecker Laura , Hinderer Matthias , Lewin Anna , Dawit Enkurie L.
Published: August 2022

Abstract. The Permian-Triassic transition was a time of climatic, tectonic as well as ecologic reorganizations at a global scale. Clastic sedimentary successions are a key archive to study the response of earth surface processes to such extensive disruptions on land. Here, we focus on the so-called Fincha Sandstone, a Karoo-equivalent fluvio- to lacustrine succession of Permian to Triassic age, deposited in the Blue Nile Basin of central Ethiopia. We use thin-section petrography, bulk-rock geochemistry, and heavy mineral spectra in order to decipher source rocks, as well as the possible contribution of chemical weathering and recycling. The results show distinct difference between Early Permian and Late Permian to Late Triassic sandstones. Petrographically, the Early Permian sandstones are rich in feldspar, and unstable heavy minerals like apatite and garnet. The average chemical index of alteration, trace, and rare earth element concentrations suggest little chemical weathering and relative proximity to the source area. This was controlled by a high topography, alluvial and braided systems and a semiarid climate. In contrast, the Late Permian and Late Triassic sandstones are quartzose, have a lower content of feldspar, and show ultra-stable heavy mineral assemblages rich in zircon, rutile, and tourmaline. The chemical index of alteration is around 80 to 90 %. This can be explained by a combination of recycling of mature platform sediments together with a humid climate reflected in deltaic-lacustrine deposits. Most probably, a corrosive environment around the Permian-Triassic Boundary has further fostered high sediment maturity. In the Middle to Late Triassic, sandstones become gradually immature again, marked by a significant increase in lithoclasts and metamorphic heavy minerals such as garnet. This trend is less visible in geochemical data because lithoclasts are fine-grained quartzose and derive from low metamorphic terrains typical for the basement of the Arabian Nubian Shield. This makes the onset of axial, NW-SE directed sediment transport through the Blue Nile Rift Basin most probable.
An improved, time-efficient approach to extract accurate distance restraints for NMR2 structure calculation
Authors: Pokharna Aditya , Torres Felix , Kadavath Harindranath , Orts Julien , Riek Roland
Published: August 2022

Abstract. Exact nuclear Overhauser enhancement (eNOE) yields highly accurate, ensemble averaged 1H–1H distance restraints with an accuracy of up to 0.1 Å for the multi-state structure determination of proteins as well as for nuclear magnetic resonance molecular replacement (NMR2) to determine the structure of the protein–ligand interaction site in a time-efficient manner. However, in the latter application, the acquired eNOEs lack the obtainable precision of 0.1 Å because of the asymmetrical nature of the filtered nuclear Overhauser enhancement spectroscopy (NOESY) experiment used in NMR2. This error is further propagated to the eNOE equations used to fit and extract the distance restraints. In this work, a new analysis method is proposed to obtain inter-molecular distance restraints from the filtered NOESY spectrum more accurately and intuitively by dividing the NOE cross peak by the corresponding diagonal peak of the ligand. The method termed diagonal-normalised eNOEs was tested on the data acquired by Torres et al. (2020) on the complex of PIN1 and a small, weak-binding phenylimidazole fragment. NMR2 calculations performed using the distances derived from diagonal-normalised eNOEs yielded the right orientation of the fragment in the binding pocket and produced a structure that more closely resembles the benchmark X-ray structure (2XP6) (Potter et al., 2010) with an average heavy-atom root-mean-square deviation (RMSD) of 1.681 Å with respect to it, when compared to the one produced with traditional NMR2 with an average heavy atom RMSD of 3.628 Å. This is attributed to the higher precision of the evaluated distance restraints.
Integrated hydrodynamic and machine learning models for compound flooding prediction in a data-scarce estuarine delta
Authors: Sampurno Joko , Vallaeys Valentin , Ardianto Randy , Hanert Emmanuel
Published: August 2022

Abstract. Flood forecasting based on hydrodynamic modeling is an essential non-structural measure against compound flooding across the globe. With the risk
increasing under climate change, all coastal areas are now in need of flood risk management strategies. Unfortunately, for local water management
agencies in developing countries, building such a model is challenging due to the limited computational resources and the scarcity of observational
data. We attempt to solve this issue by proposing an integrated hydrodynamic and machine learning (ML) approach to predict water level dynamics as a
proxy for the risk of compound flooding in a data-scarce delta. As a case study, this integrated approach is implemented in Pontianak, the densest coastal
urban area over the Kapuas River delta, Indonesia. Firstly, we build a hydrodynamic model to simulate several compound flooding scenarios. The
outputs are then used to train the ML model. To obtain a robust ML model, we consider three ML
algorithms, i.e., random forest (RF), multiple linear regression (MLR), and support vector machine (SVM). Our results show that the integrated scheme works well. The RF is the most accurate algorithm to model water level dynamics in the study area. Meanwhile, the ML model using the RF
algorithm can predict 11 out of 17 compound flooding events during the implementation phase. It could be concluded that RF is the most
appropriate algorithm to build a reliable ML model capable of estimating the river's water level dynamics within Pontianak, whose output can be used as a proxy for predicting compound flooding events in the city.

Based on the low-carbon obligation fulfillment of Chinese logistics enterprises, this study constructs a tripartite evolutionary game model to analyze the evolutionary process of the interaction between the local government, logistics enterprises and the public in the process of low-carbon behavior credit supervision. Then using Netlogo software, a parameter simulation experiment is conducted to determine the optimal policy for improving the effect of supervision. The results are as follows: ① The combined influence of the local government and the public can effectively change the strategic choice of enterprises and promote the low-carbon behavior of enterprises. ② In terms of improving the effect of supervision, reducing the cost of government supervision would have a highly significant effect, and reducing the cost of the public would be counterproductive. ③ Increasing the government subsidies to enterprises and the government’s fines to enterprises both have a significant effect, and the effect of improving the former is better. However, increasing the severity of higher-level governments punishing local governments will reduce the stability of the system. ④ Supervision can be more effective by increasing the public’s impact on enterprises’ earnings rather than by increasing government subsidies to the public.
La Fisonomía Propia de la Acción Popular en Bolivia.

El Estado garantiza el ejercicio los derechos reconocidos por la Constitución Política del Estado y, para este efecto, otorgó medios de protección contra todo acto u omisión de autoridades, personas individuales o colectivas tendientes a impedir el ejercicio efectivo de los mismos. A esos medios de protección se denominan acciones tutelares. En el caso particular de la Acción Popular es el medio de protección y de defensa inmediata, idóneo ante la violación o la intención de violar derechos, intereses colectivos o difusos relacionados con el patrimonio, el espacio, la seguridad y la salubridad pública, el medio ambiente y otros de similar naturaleza reconocidos por la Constitución Política del Estado.
Esta acción constitucional de defensa a los derechos e intereses colectivos o difusos es novísima dentro del ordenamiento jurídico del Estado boliviano. Su inserción y reconocimiento en nuestra economía jurídica fue mediante la reforma constitucional del 2009. Aun siendo la acción constitucional de defensa más joven dentro del ordenamiento jurídico boliviano, por la reciente data de su inserción, se cuenta con una cantidad de Sentencias Constitucionales que las resuelven, de las cuales nos podemos valer con el objeto de entender la fisonomía propia de esta acción en el Estado Plurinacional de Bolivia, conocer su naturaleza jurídica e identificar sus características a través de las líneas jurisprudenciales establecidas por el Tribunal Constitucional Plurinacional.

The efficiency of the electrohydrodynamic (EHD) cooling and thermostating systems of electronic and electrical devices is investigated. A design of electroconvective cooling of an X-ray generator is proposed, the effectiveness of which is confirmed on laboratory models and full-scale samples. The anode temperature was reduced by a factor of two, the duration of the emitter operation increased, the reliability of the device improved. Various methods of cooling a high-voltage transformer are presented allowing to increase the specific power, reduce the weigh, size parameters, and temperature of the coolant, augment the resource. Studies have been conducted to establish the possibility of thermostating the heat-emitting element (block) by EHD methods when both external and internal conditions change. The design of an EHD thermostat with an automatic thermal stabilization system has been developed and tested (the temperature is maintained with an accuracy of ± 0.05 °С). A frame with an EHD liquid circuit and an EHD thermostat has been designed, which allows to significantly reduce longitudinal temperature differences and its deformation. The high efficiency of EHD cooling methods is shown by an example of a block of light-emitting diodes, small elements and components of electronic equipment, the use of electrodes – wires with a perforated insulating coating when cooling flat heat-emitting surfaces; a sevenfold increase in the heat transfer coefficient is achieved.

This study aims to determine the influence of Gross Profit Margin, Receivable Turn Over and Long Term Debt to Equity Ratio on Stock Price with Current Ratio and Dividen Yield Ratio as moderating variables.  This study used the object of the Batubara subsector company on the Southeast Asian Stock Exchange for the period 2012-2020. The data collected is secondary data with documentation methods in the form of company annual reports. The analysis tool used to test hypotheses is the IBM SPPS V26. The sampling method used in this study using purposive sampling techniques was obtained by 9 companies that presented complete financial statements, so that 81 samples were obtained. The analytical techniques used are deskriptif statistical analysis, classical assumption test, moderated regression analysis (MRA), multiple linear regression, t test test, and f test.  The results of the study partially concluded that Gross Profit Margin  has no significant effect on Stock Price, Receivable Turn Over has a significant effect on Stock Price and Long Term Debt to Equity Ratio has no significant effect on Stock price.  The results of the study simultaneously showed that the value of Fcount 13,962 and Ftable 2,72 means that Fcount > Ftable or a significant value of 0,000<0,05. So far, Gross Profit Margin, Receivable Turn Over and Long Term Debt to Equity Ratio simultaneously have a significant effect on Stock Prices. The results of moderately regression analysis (MRA) research show that Current Ratio does not moderate Gross Profit Margin to Stock Prices, Current Ratio does moderate Receivable Turn Over to Stock Price and Current Ratio does not moderate Long Term Debt to Equity Ratio on Stock Prices, Dividen Yield Ratio does not moderate Gross Profit Margin to Stock Prices, Dividen Yield Ratio does moderate Receivable Turn Over to Stock Price and Dividen Yield Ratio does not moderate Long Term Debt to Equity Ratio on Stock Prices.
