Published: October 2021

Digitalization is developing rapidly in the community, but not all levels of society can use technology properly including students. So that it needs an active role of universities in directing students to be more effective in using technology as a learning support facility. The purpose of the study was to determine the extent to which the use of e-learning in the Economic Education Study Program of STKIP PGRI Lumajang can spur student academic activities on an ongoing basis so as to improve the quality of learning. This type of research uses a qualitative phenomenological approach. The research method uses in-depth interviews, observations and questionnaires. Found the results of the first study, most of the students of Economic Education Study Program were able to use e-learning well. Second, the intensity of e-learning media usage is not routinely fully used by students because not all subjects are given through e-learning media. Finally, the use of e-learning media provides an attraction to encourage students to be more active, more effective in understanding the material, more efficient in terms of time and cost. The main problem that arises is the unstable internet network connectivity because most student residences are in locations that are difficult to reach with a strong internet network so they have to struggle more to be able to access e-learning.
Modeling and Analysis of Carbonate Matrix Acidizing Using a New Two-Scale Continuum Model
Authors: Jia Cunqi , Sepehrnoori Kamy , Huang Zhaoqin , Yao Jun 
Published: October 2021

SummaryMatrix acidizing is a common technique for carbonate reservoir stimulation. In this work, a new two-scale continuum model is developed to study the 2D acidizing process. The Navier-Stokes-Darcy equation is used instead of the Darcy’s-law equation to describe fluid flow. The continuity equation is also modified to consider the mass-exchange term between fluid and solid phases. The comparison results show that neglecting the solid-matrix-dissolution source term results in overestimation of pore volume (PV) to breakthrough (PVBT). The Darcy’s-law equation does not well-capture physical behaviors of fluid phase with low acid-injection velocity compared with the Navier-Stokes-Darcy equation. On the basis of this model, we discuss different processes influencing matrix acidizing, including convection, diffusion, and reaction, and different models, including classical and new two-scale continuum models. Besides, a comprehensive parametric study is also conducted to study the effect of parameters with respect to acid and rock physical parameters on the matrix-acidizing process. The typical dissolution patterns and optimal acid-injection rate presented in experimental studies can be well-observed by the new two-scale continuum model. Increasing the acid-injection concentration has a limited effect on the amount of acid mass but substantially reduces the amount of solute required. The acidizing curve is very sensitive to the dispersity coefficient, acid-surface-reaction rate, and porosity/permeability relationship.

Abstract
This paper presents an experimental study of improved oil recovery from fractured shale cores by huff-n-puff of the aqueous solutions of 3-pentanone. The huff-n-puff experiments with different 3-pentanone concentrations were analyzed by the material balance for components: oil, brine, and 3-pentanone. Naturally sulfate-rich brine of low salinity was used as the injection brine.
Results show that the 3-pentanone solution recovered more oil from the shale matrix than the injection brine alone. The oil recovery increased when the 3-pentanone concentration increased from 0.56-wt% to 2.85-wt%. Huff-n-puff with the 2.85-wt% 3-pentanone solution showed the highest improved oil recovery by 3-pentanone. However, the huff-n-puff experiment with the 1.07-wt% 3-pentanone solution showed the highest efficiency measured by the mass ratio of the produced oil to the injected 3-pentanone. That is, an optimal concentration of 3-pentanone appeared to exist. The material balance analysis showed that 3-pentanone was efficiently imbibed into the shale matrix, and that oil was recovered from shale mainly by the displacement by brine after the wettability alteration by 3-pentanone.

Abstract
The work described in this paper details the development of a single stimulation package that was successfully used for treating an offshore horizontal polymer injection well to improve near wellbore injectivity in the Captain field, offshore UK. The practice was to pump these concentrated surfactant streams using multiple pumps from a stimulation vessel which is diluted with the polymer injection stream in the platform to be injected downhole. The operational challenges were maintaining steady injection rates of the different liquid streams which was exacerbated by the viscous nature of the concentrated surfactants that would require pre-dilution using cosolvent or heating the concentrated solutions before pumping to make them flowable. We have developed a single, concentrated liquid blend of surfactant, polymer and cosolvent that was used in near-wellbore remediation. This approach significantly simplifies the chemical remediation process in the field while also ensuring consistent product quality and efficiency. The developed single package is multiphase, multicomponent in nature that can be readily pumped. This blend was formulated based on the previous stimulation experience where concentrated surfactant packages were confirmed to work. Commercial blending of the single package was carried out based on lab scale to yard scale blending and dilution studies. About 420 MT of the blend was manufactured, stored, and transported by rail, road and offshore stimulation vessel to the field location and successfully injected.
Hydrocarbon Field Re-Development in a Bayesian Framework
Authors: Steineder Dominik , Clemens Torsten 
Published: October 2021

Abstract
Hydrocarbon field (re-)development projects are challenging to perform as a number of decisions need to be taken under uncertainty. In addition, data gathering activities need to be performed to decrease the risk of negative outcomes related to project objectives and to select the development option with the highest value.
Many oil and gas E&P companies are using as stage-gate process to mature hydrocarbon field (re-)development projects. Such a process allows for systematic project development including value assurance measures such as peer reviews prior to decision gates. However, the stage-gate leads to challenges if it is not performed in a Bayesian framework. If for example simplified models are used in the early phase of the stage-gate process, no Bayesian updating of believes can be done. Similarly, if the company is not seamlessly integrating project value in project development, the value of development option and of data acquisition cannot be quantitatively determined.
We are showing how to mature projects in a Bayesian framework. We show how data gathering is used to update believes and how generalized sensitivity analysis can be applied to identify which decisions have an impact of project value and which parameters are sensitive to the decision which development option to perform. The key performance indicators such as Expected Monetary Value, Probability of Maturation, Probability of Economic Success are updated. The changes of the sensitivities of the various uncertain parameters with project maturation is monitored and the decision maker is supplied with key performance indicators and residual risks, risk mitigation and management plans at Final Investment Decision.

New data on well-known drug: focus on meldonium
Authors: Statsenko M. E. , Turkina S. V. , Lopushkova Yu. E. 
Published: October 2021

The article reviews the efficacy of meldonium in patients with various diseases, which are based on secondary mitochondrial dysfunction. Mitochondria are complex cellular organelles that control many metabolic processes, including fatty acid oxidation, the Krebs cycle, oxidative phosphorylation in the electron transport chain, and many other processes. Many conditions can lead to secondary mitochondrial dysfunction and affect other diseases. Damage to mitochondria can promote the activation of free radical processes and the initiation of the mechanisms of programmed cell death, mitochondrial dysfunction decrease in the immune response, increase in the activity of the body’s inflammatory response in various infections. Mitochondria appear to be important in COVID-19 pathogenesis because of its role in innate antiviral immunity, as well as inflammation. The article presents data on the effectiveness of using meldonium as a drug that helps to arrest pathological processes in mitochondria. The main mechanism of action of meldonium is based on a decrease in L-carnitine levels and increase of peroxisomes activity in the cytosol Meldonium was designed as a inhibitor of carnitine biosynthesis aimed to prevent accumulation of cytotoxic intermediate products of fatty acid beta- oxidation in ischemic tissues and to block this highly oxygen- consuming process. It is based on the correction of the energy metabolism of the cell. There was a positive trend in the use of meldonium in patients with diseases of the cardiovascular system (chronic ischemic diseases, chronic heart failure, arterial hypertension, etc.), neurological disorders (stroke, cerebrovascular insufficiency, etc.), respiratory diseases. The data on the beneficial effect of meldonium on the immune response in patients with coronavirus, bronchial asthma, chronic obstructive pulmonary disease, during vaccination with anti-influenza serum are presented. A decrease in asthenia was noted against the background of the use of meldonium in patients who had undergone coronavirus infection.

Published: October 2021

Introduction. Currently, there is insufficient data on the effect of modern antihypertensive therapy (AHT) on venous circulation, especially during physiological stress.Aim of the study – the investigation was to study the hemodynamic effects of a combination of a calcium channel blocker (CCB) and an angiotensin-converting enzyme (ACE) inhibitor during exercise in men with arterial hypertension (AH) and chronic venous diseases (CVD).Material and methods. In 46 men 30–50 years old with AH on the background of AHT, a comparative assessment of the dynamics of SBP, DBP, peripheral venous pressure (PVP), ultrasound parameters of venous blood flow of the left leg in response to physical activity (Ruffier’s test) was performed. The parameters were assessed in 23 patients with hypertension without CVD and 23 patients with hypertension and CVD. We studied the reaction before and after 14 days of combined AHT with the use of CCB (Amlodipine) and an ACE inhibitor (Lisinopril).Results. Before treatment, the response to exercise in patients of both groups was the same and was manifested by a twofold increase in the area of the lumen of the veins and a drop in blood flow velocity. Patients with CVD before treatment with exercise were characterized by an altered systemic hemodynamic response, more frequent cases of venous dilatation and decreased blood flow velocity. After AHT with exercise, both groups showed normalization and identity of SBP. DBP, PVP, a decrease in the severity of venous dilatation and a decrease in blood flow velocity. Patients with CVD after AHT in response to exercise are characterized by more pronounced venous dilatation and higher blood flow velocity.Conclusion. After 14 days of antihypertensive therapy in patients with hypertension without chronic venous disease and in patients with hypertension and chronic venous disease during exercise normalization of systolic blood pressure, diastolic blood pressure, PVP, a decrease in venous dilatation and a decrease in blood flow velocity are noted. Patients with CVD after AHT under load are characterized by varicose veins and accelerated venous blood flow.

Background:Despite the widespread use of combination antiretroviral therapy (cART), HIV-associated neurocognitive impairment (NCI) persists in people living with HIV (PLWH). Studies have generated inconsistent results regarding etiological factors for NCI in PLWH. Furthermore, a user-friendly and readily available predictive tool is desirable in clinical practice to screen PLWH for NCI.Objective:This study aimed to identify factors associated with NCI using a large and diverse sample of PLWH and build a nomogram based on demographic, clinical, and behavioral variables.Methods:We performed Bayesian network analysis using a supervised learning technique with the Markov Blanket (MB) algorithm. Logistic regression was also conducted to obtain the adjusted regression coefficients to construct the nomogram.Results:Among 1,307 participants, 21.6% were neurocognitively impaired. During the MB analysis, age provided the highest amount of mutual information (0.0333). Logistic regression also showed that old age (>50 vs. ≤50 years) had the strongest association (OR=2.77, 95% CI=1.99-3.85) with NCI. The highest possible points on the nomogram were 626, translated to a nomogram-predicted probability of NCI to be approximately 0.95. The receiver operating characteristic (ROC) curve's concordance index was 0.75, and the nomogram's calibration plot exhibited an excellent agreement between observed and predicted probabilities.Conclusion:The nomogram used variables that can be easily measured in clinical settings and, thus, easy to implement within a clinic or web-interface platform. The nomogram may help clinicians screen for patients with a high probability of having NCI and thus needing a comprehensive neurocognitive assessment for early diagnosis and appropriate management.
