Authors: VODNAR Dan Cristian , SOCACIU Carmen 
Published: December 2021

The metabolic activity and behavior of Lactobacillus casei were investigated during lactic fermentation and after microencapsulation. L.casei metabolic activity in vitro was investigated by HPLC and Infrared spectrometry (FTIR). Following the fermentation during 78 h, we identified lactic acid (retention time at 4.59 min) and its synthesis to begin after 3h and increasing gradually, up to a productivity of 6.89 mg mL-1 after 78 h. We noticed a high activity in the first 6 hours, and the media was totally consumed before 12 hours. By FT-IR fingerprint during fermentation we identified changes of the spectra pattern, specific increasing peaks of lactic acid (1127 cm-1) during fermentation (from 3 to 78 h) and other specific absorption peaks at 1420 cm-1, 2845 and 2929 cm-1.
The comparative behavior of L.casei microencapsulated in different matrices, in simulated gastric and intestinal juice were also studied. L.casei was microencapsulated in sodium alginate (AG), chitosan (CH), alginate: guar gum (AG:GU) and alginate: xanthan gum (AG:XA). The microencapsulation effects on the changes in survival rate of bacteria, during exposure in simulated gastric and intestinal juice were studied. The survivability of the strains, were expressed as the destructive value (decimal reduction time). The alginate beads 2% prevented acid-induced reduction of the cell density in simulated gastric juice, resulting in significant (P

INDUCTIVE PARAMETRIC EDDY-CURRENT TRANSDUCER (IPEP) FOR MEASURING ELECTRICAL AND TEMPERATURE PARAMETERS OF WASTEWATER FROM BREWING PRODUCTION
Authors: Sebko Vadim , Babenko Volodymyr , Pyrozhenko Yevheniia 
Published: December 2021

The possibility of using the theory of operation of a differential inductive parametric eddy-current transducer (IPET) for measuring the electrical and temperature parameters of a sample of acidic and alkaline wastewater is investigated. The need for the development of new informative methods for measuring the physicochemical parameters of wastewater is proved, in the realization of which a promising method of purification is selected. On the basis of a differential scheme for switching on two parametric converters: with exemplary purified water and a converter in which a test tube with a sample of waste water from a brewing production is placed, a differential informative method for measuring the electrical and temperature parameters of the liquid under study is proposed, which is based on the analysis of the components of the difference signal of phase shift angles measured electrical components of the switching circuit signals. The basic relationships that describe the operation of the IPET with the sample of the controlled liquid are given. The scheme of switching on differential IPET with a liquid sample, which is placed in a glass test tube, is considered; the differential scheme provides for heating the sample during measurements to simulate the production conditions of brewing production. Universal transformation functions are given that relate the components of the IPET signals with the specific electrical conductivity χt.s. and the temperature t of the wastewater sample from brewing production, that is, the dependence of the phase difference signal Δj on the generalized parameter A and the dependence of the absolute increment in the specific electrical conductivity Δχ on the temperature t of the wastewater sample, in the investigated temperature range.
MODELING OF PRODUCING PRESSURE IN HETEROGENEOUS OIL-BEARING RESERVOIRS

Published: December 2021

Numerical modeling of the distribution of the reservoir pressure drop in the vicinity of an operating well was carried out taking into account the inhomogeneous distribution of filtration characteristics (permeability and oil viscosity) in the near and distant zones of the well operation in order to study the practical aspects of filtration in heterogeneous oil-bearing formations based on a combined finite-element-difference method for non-stationary problem of piezoconductivity. The use of the combined finite-element-difference method enables to combine the advantages of the finite-element method and the finite difference method: to model geometrically complex areas, to find the value at any point of the object under study, while the implicit difference scheme.
It is shown that the intensity of filtration processes in the vicinity of the operating well depends mainly on the permeability, and, to a lesser extent, on the viscosity of the oil. Moreover, the influence of the permeability of the oil phase in the remote zone (Rd < 5 m) is greater than the effect in the close zone (Rd > 5 m) of the operating well. In the case of low permeability of the oil phase in the vicinity of the existing well, to maintain stable oil production, it is necessary to place an injection well near the production well. Using the method suggested, it is possible to predict the effect of the injection well on the formation pressure distribution in the formation.
The scientific novelty of the work lies in the study of the influence of the heterogeneous permeability and oil viscosity distribution on the reservoir pressures distribution around the wells by modeling filtration processes based on a combined finite-element-difference method.
The practical significance of the research results comes down to confirming the close relationship between the heterogeneity of the porous medium and the reservoir pressures distribution around an operating producing well. The combined finite-element-difference method used in this work can be used to solve other filtration problems (for example, to calculate the gas saturation of a reservoir, create a method for calculating well flow rates, assess the effect of injection wells on filtration processes).

Published: December 2021

Traditional image processing techniques provide sustainable efficiency in the astrometry of deep space objects and in applied problems of determining the parameters of artificial satellite orbits. But the speed of the computing architecture and the functions of small optical systems are rapidly developing thus contribute to the use of a dynamic video stream for detecting and initializing space objects. The purpose of this paper is to automate the processing of optical measurement data during detecting space objects and numerical methods for the initial orbit determination.This article provided the implementation of a low-cost autonomous optical system for detecting of space objects with remote control elements. The basic algorithm model had developed and tested within the framework of remote control of a simplified optical system based on a Raspberry Pi 4 single-board computer with a modular camera. Under laboratory conditions, the satellite trajectory had simulated for an initial assessment of the compiled algorithmic modules of the computer vision library OpenCV.Based on the simulation results, dynamic detection of the International Space Station in real-time from the observation site with coordinates longitude 25o41′49″ East, latitude 53o52′36″ North in the interval 00:54:00–00:54:30 17.07.2021 (UTC + 03:00) had performed. The video processing result of the pass had demonstrated in the form of centroid coordinates of the International Space Station in the image plane with a timestamps interval of which is 0.2 s.This approach provides an autonomous raw data extraction of a space object for numerical methods for the initial determination of its orbit.
What Is Really Happening When Parent and Child Wells Interact?
Authors: Jacobs Trent 
Published: December 2021

When trying to understand the well-to-well events known as frac hits and fracture-driven interactions (FDIs), the first idea to embrace is this: they are not all the same.
“And the key physical mechanisms are not the same,” said Mark McClure, who added that, “Until you’ve really dialed in on what those are, you’re really in the dark.”
McClure is the cofounder and CEO of ResFrac Corp. In March, the modeling firm began a multiclient study to diagnose the relationships between parent and child wells—or what many consider to be the ultimate subsurface challenge facing the shale sector.
Participating operators are Marathon Oil, Hess Corp., Pioneer Resources, Arc Resources, Birchcliff Energy, SM Energy, and Ovintiv Inc. These independent E&Ps represent a cross section of some of the most active plays in North America: the Midland and Delaware basins and the Bakken and Montney shales.
But what makes the study unique, McClure said, is that it involves 10 rich data sets from well pads that were subjected to a number of cross-validating diagnostics: tracers, pressure/interference monitoring, geochemistry, and fiber optics. ResFrac has been using that data to calibrate its coupled reservoir-fracture models to see what knobs clients might want to turn in the future to improve well economics.
The study is also trying to unearth some firm answers about what is really happening during offset stimulations, why it is happening, and what can be done to mitigate negative outcomes. ResFrac and its clients expect to wrap up this part of the study by the year’s end and to submit an abstract for an SPE technical conference in 2022.
As the study nears an end, McClure offered some of his key observations that he noted are supported by previous research found within industry literature.

So, What’s the Worst That Can Happen?
A growing chorus of subsurface experts consider unwanted chemical reactions in the fracture network as one of the major damage mechanisms resulting from FDIs. McClure is not only among them, he said chemical effects represent the “worst” that can happen when parents and children interact.
“This is where you see wells get hit, they lose 80% of their production, and it doesn’t come back,” he explained. Some in the industry have taken to calling the byproduct of these chemical reactions “shmoo” or “gunk.” For answers as to why this is happening, McClure points to two technical papers in particular.
Decision Tree Regressions Estimate Liquid Holdup in Two-Phase Gas/Liquid Flows
Authors: Carpenter Chris 
Published: December 2021

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 203448, “Decision-Tree Regressions for Estimating Liquid Holdup in Two-Phase Gas/Liquid Flows,” by Meshal Almashan, SPE, Yoshiaki Narusue, and Hiroyuki Morikawa, University of Tokyo, prepared for the 2020 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, held virtually 9–12 November. The paper has not been peer reviewed.
In the authors’ study, a machine-learning predictive model—boosted decision tree regression (BDTR)—is trained, tested, and evaluated in predicting liquid holdup (HL) in multiphase flows in oil and gas wells. Results show that the proposed BDTR model outperforms the best empirical correlations and the fuzzy-logic model used in estimating HL in gas/liquid multiphase flows. Using the BDTR model with its interpretable representation, the heuristic feature importance of the input features used in building the model can be determined clearly.

Introduction
Machine-learning approaches in predicting HL in multiphase flows have been recently studied to improve prediction accuracy compared with existing empirical correlations. However, these approaches ignore the heuristic feature importance of the input parameters to the predicted HL values. The heuristic feature importance can help provide better insight into the issues associated with HL studies, such as the liquid-loading phenomenon. To the best of the authors’ knowledge, the present study is the first work that shows how decision-forest regression predictive models can predict HL accurately.

Data Acquisition
The performance and the predictive power of a machine-learning model relies greatly on the quality and completeness of the data set used in building the model. The data sets used in training and testing the predictive model are experimental and were collected from the literature (111 data points). Air/kerosene and air/water mixtures were used in obtaining the 111 experimental data points. In this study, this data set is divided into three different subsets: training, validation, and testing.
The data sets consist of the properties of HL, the superficial gas velocity (Vsg), the superficial liquid velocity (Vsl), pressure, and temperature (T). The statistical measures of the data sets are shown in Table 1 of the complete paper.

Published: December 2021

Abstract
Background: The efficacy, safety, and clinical outcomes for patients switch to generic rosuvastatin, compared with patients taking other brand-name atorvastatin, is unclear. Method: We retrospectively collected electronic medical records from January 1, 2013, to December 31, 2020, of patients who switched medication, because of hospital policy, from brand-name to generic rosuvastatin after March 14, 2018. we only considered patients who had taken the medication at least 1 year prior to and 1 year after that date. We also collected records of patients who consistently used brand-name atorvastatin during the same period. The efficacy of lipid control, potential adverse effects, clinical outcomes of major cardiovascular events (MACE), and medical expenses were compared between the 2 groups. Propensity score matching (PSM) was conducted to balance potential cofounders. Result: After 1:1 PSM, 592 patients were enrolled in the rosuvastatin and atorvastatin groups, and no significant difference was observed in their total cholesterol (TC) level difference (−4.38 ± 23.0 vs. −3.72 ± 26.95 mg/dL, P = 0.702), low-density lipoprotein (LDL-C) (−2.38 ± 19.89 vs. −2.42 ± 23.63 mg/dL, P = 0.976), or glycated hemoglobin (−0.05% ± 0.7% vs. −0.08% ± 0.76%, P = 0.543). No significant differences were noted in their cumulative MACE (2.70% vs. 3.89%, log-rank P = 0.265) after the switch date, and each person in the generic group had a 16% average reduction in their medical expenses. Conclusion: Switching to generic rosuvastatin led to comparable lipid-lowering efficacy, safety, and clinical outcomes and fewer medical expenses compared with consistently using brand-name atorvastatin.
Dialysis Access-Associated Steal Syndrome with Percutaneous Endovascular Arteriovenous Fistula Creation.
Authors: Varma Rakesh , Betancourt-Torres Manuel , Bready Eric , Al-Balas Alian 
Published: December 2021

Abstract
Background: Dialysis access-associated steal syndrome is an infrequent complication after hemodialysis access creation. Clinical symptoms depend on the degree of steal. Mild symptoms include coldness, numbness and pain during dialysis. Severe steal can present with rest pain, cyanosis and ulcerations, and may require surgical ligation of the fistula. With recent advances in arteriovenous fistula creation, percutaneous endovascular arteriovenous fistula creation has demonstrated better maturation and patency rates with lower risk of wound healing and infection rates as compared to surgically created hemodialysis access. Percutaneous creation offers a minimally invasive alternative, though complications have been reported. The following presents the first described case of DASS following the use of percutaneous endovascular arteriovenous fistula creation, and discusses risk factors and management. Case Presentation: Our case is that of a 27-year-old male with end stage renal disease due to congenital renal dysplasia, who underwent left percutaneous arteriovenous fistula creation for initiation of dialysis. Two months after the procedure the patient complained of coldness, pain, tingling, and numbness in the left arm during dialysis, concerning for steal syndrome. The patient subsequently underwent brachial artery angiogram, which showed predominant flow through the fistula and minimal antegrade flow through the ulnar and interosseous arteries towards the hand, with a focal, severe stenosis in the distal ulnar artery. Angioplasty of the stenosis was performed, though steal symptoms continued. Conclusions: DASS, though rare, can be seen with percutaneous arteriovenous fistula creation. Identification of the risk factors prior to creation, especially in patients who are at higher risk of peripheral vascular disease, can help avoid this complication. Management is largely guided by clinical presentation. As long as there is adequate collateral supply to the extremity, single vessel occlusion is not a contraindication to percutaneous arteriovenous fistula creation with the use of WavelinQ technology. Careful patient selection with pre-creation angiogram may reduce the risk of symptomatic steal.
