Authors: Al-Qasim Abdulaziz , Al-Tayyib Deena , Katterbauer Klemens 
Published: February 2023

AbstractThe topic of carbon dioxide (CO2) enhanced oil recovery (EOR) has received increased attention since five decades for two main applications: Improvement of oil recovery in reservoirs, using miscible CO2 injection as tertiary oil recovery technique. Carbon dioxide can be injected into the reservoir using different injection strategies: injected by itself, simultaneously injected with water or as water-alternating-gas (WAG) mode. CO2 can be found in different phase states: liquid, gas or supercritical, depending on the reservoir conditions (pressure/temperature).CO2 sequestration (geologic storage) as a way to reduce CO2 emission. The realization of the CO2 sequestration into reservoir requires that long term stability of the reservoir seal is ensured.It is considered that measuring electric resistivity is useful to monitor CO2 migration in the reservoir. Resistivity shows a high sensitivity to fluids saturation in reservoirs. Therefore, it is considered that deep electromagnetic technologies (e.g., crosswell EM) can also be useful as a surveillance method in case of CO2 injection. The variation of resistivity due to CO2 injection into a carbonate reservoir is not thoroughly studied, especially in a mixed salinity environment. Thus, the study presented in this paper provides a better understanding of the resisitivity responses in a mixed-salinity carbonate cores during drainange, imbibtion and CO2 injection processes, which may aid in CO2 montiroing.The study addresses the following objectives: Conduct the flooding tests on one carbonate core plug, varying the brine salinity.Conduct the CO2 injection at reservoir conditions.Measure resistivity of cores at different injection rates of CO2 into a carbonate plug, already partially saturated with brine and oil.Monitor a change in the overall resistivity of the rock while CO2 is being injected at different rates and also at a constant rate.Investigate the frequency effect on resistivity response while injecting fluids.
Salinity Effect on the Interfacial Tension of CO2-Brine: Estimation and Investigation by Molecular Dynamics Simulations
Authors: Shiga Masashige , Sorai Masao 
Published: February 2023

AbstractWhile there are numerous experimental data on CO2-brine interfacial tension (IFT), few studies on salinity effects over a wide range of concentrations have been reported. Thus, there is room for further research in understanding the mechanism of the IFT change. The objective of this study is to estimate the effect of salinity on CO2-brine IFT by molecular dynamics (MD) simulations and to gain a better understanding of the phenomenon through microscale insight.IFT of CO2-brine was calculated for a wide range of salinity conditions from pure water to 5 mol/kg NaCl solution at temperatures and pressures from 298 to 473 K and 8 to 20 MPa. To calculate IFT, MD was performed by using the Nosé-Hoover thermostat and the Parrinello-Rahman barostat to keep temperatures and pressures constant.The calculated results show an increasing trend against salinity, which is in good agreement with experimental data from previous studies. For example, the IFT under typical reservoir conditions of 313 K and 10 MPa were 30.0 mN/m for pure water, while 31.9, 34.2, 36.9, 39.4, and 42.6 mN/m for 1, 2, 3, 4, and 5 mol/kg NaCl solutions, respectively. The density distribution of ions in the aqueous phase near the interface and in the bulk region captured the negative adsorption of ions. This enables us to interpret the mechanism of the increase of IFT in light of the Gibbs adsorption isotherm.IFT data calculated in this study is beneficial for estimating and modeling fluid behaviors of CO2-brine systems under a wide range of salinity conditions. In addition, atomic-scale insights would contribute to a better understanding of the interfacial phenomena regarding CO2-brine including high salinity regions.

AbstractThe surface crude oil viscosity of the first ultra-heavy oil field in Bohai Oilfield is more than 50,00mpa·s, which is unable to be developed under the condition of original formation temperature and requires steam stimulation. In the first period of steam huff and puff well, due to sufficient formation energy, steam injection pressure is high in the process of steam injection. The measures to reduce the steam injection speed are mostly adopted in the field, but it will lead to the problem of large wellbore heat loss and affect the steam stimulation heat injection effect. In this paper, based on the oil characteristics of the first ultra-heavy oil field in Bohai Oilfield, the evaluation of oil soluble surfactant was carried out, and the experimental study of pre-injection of oil soluble surfactant to reduce steam injection pressure was carried out. It has been successfully applied in the development of the first ultra-heavy oil in Bohai oilfield. The results show that the oil soluble surfactant with asphaltene dispersibility has better temperature resistance and viscosity reduction effect, and the viscosity reduction effect is more than 95% before and after aging. Laboratory experiments show that the oil soluble surfactant can reduce the steam displacement resistance of the displacement front and the affected area. When the injection amount of oil soluble surfactant is 0.2PV, the maximum steam injection pressure can be reduced by 22.9% and the steady steam injection pressure by 10.8%. The design treatment radius of oil soluble surfactant is 0.15m, and the field test shows that the steam injection pressure decreases by 1.1MPa during steam injection.After adopting the depressurization and increase injection volume technology, the field injection pressure is effectively reduced, the steam injection effect of ultra-heavy oil is guaranteed, and the technical guarantee for the subsequent development, promotion and application of ultra-heavy oil is provided.

Published: February 2023

Dünyanın küreselleşmesi ile birlikte çok kültürlü ve sürekli yeniden şekillenen yaşam biçimlerinin yaygınlaşmasının beraberinde yeni dinamikler getirdiği ve bunların en başta dilimize de yansıdığı yadsınamaz. Politik doğruluk, bu süreç içinde karşımıza çıkan ve genellikle farklı dil, din, kültür ve cinsiyetten kişileri incitmekten kaçınmak amacıyla, özenle kullanılan ifade, düşünce ve uygulamaları tanımlamak amacıyla kullanılan bir terimdir. Dolayısıyla kavramın temel amaçlarından biri sosyal açıdan dezavantajlı olan birey veya gruplar hakkında konuşurken, onları ötekileştirebilecek veya kötü hissettirebilecek ifadeleri kullanmaktan kaçınmakken bir diğer amacı bireyin kendini toplum içinde „farklılığı“ sebebiyle dilsel olarak dışlanmış ve ayrımcılığa uğramış hissetmesini önlemeye yönelik bir farkındalık yaratmaktır.
Araştırmada günümüzün bir ihtiyacı olarak karşımıza çıkan „Politik Doğruluk“ kavramının günümüz Türkiye‘sinin gündeminde ve disiplinler arası tartışmalarda da çoktan yerini aldığı, fakat daha ziyade medya acısından ele alındığı ve henüz çeviri bilimsel açıdan pek irdelenmediği görülmüştür. Dolayısıyla bu çalışmanın temel amacı; çoğu zaman belirli bir derecede ideolojik ideallere hizmet eden Çocuk Edebiyatının hem dil içi (intralingual) hem de diller arası (interlingual) çeviri yoluyla, ön yargıları ve toplumsal eşitsizlikleri nasıl yeniden ürettiğini ya da onları nasıl yıkabileceğini veya en azından bu konu ile ilgili nasıl bir farkındalık yaratabileceğini ortaya koymak ve bu vesile ile çeviri ile politik doğruluk arasındaki ilişkiyi tartışmaktır. Bu amaç doğrultusunda örnek incelemesi olarak Alman Çocuk Edebiyatındaki gelişmeler ele alınarak çeviri bilimsel açıdan örneklendirilecek ve çeviri yaparken Politik Doğruluk açısından uygun olan sözcükleri belirlemeye yardımcı olması açısından Lasswell İletişim Modelinin nasıl uygulanabileceğine değinilecektir.

Published: February 2023

Mastering English in academic context is prominent to prepare university students for global competition, and thereforeÂ awareness of academic self-efficacy towards language skills is needed to learn English correctly and effectively. This study aims to examine the academic self efficacy of students from International Program who took Bridging program Course. To collect the data, the researcher distributed a questionnaire by Djokic (2021) that was adapted from Owen and Fromanâ€™s (1988) College Academic Self Efficacy Scale (CASES). The data show that students from Bridging Program course have the highest efficacy when it comes to attending the lectures. However, they have the lowest efficacy on their note-taking skill and their ability to answer questions from the professors. The result implied that students were more confident in doing a routine activity as they are accustomed in it, and felt less confident when they have to respond to lecturers as it required their readiness to learn.
Delayed open treatment of aortic penetration by a thoracic pedicle screw: illustrative case
Authors: Levy Hannah A. , Pinter Zachariah W. , Hobson Sandra L. , Yaszemski Michael J. 
Published: February 2023

BACKGROUND
Iatrogenic aortic injury from pedicle screw malpositioning or anterior prominence in posterior spinal fusion represents a rare but potentially devasting complication. While intraoperative aortic injury is associated with hemodynamic instability, delayed presentations of pedicle screw aortic impingement or violation often present insidiously with pseudoaneurysm or vascular remodeling in clinically asymptomatic patients. Currently, there is a lack of guidance in the field for the recommended surveillance, urgency of operative intervention, and optimal surgical management of delayed pedicle screw aortic injuries.

OBSERVATIONS
The following case study discusses the open treatment of delayed thoracic aortic penetration from an excessively long T12 pedicle screw in an asymptomatic adolescent patient with idiopathic scoliosis. The pedicle screw prominence anteriorly was corrected by burring the screw tip until it was flush with the vertebral body. The associated aortic injury was addressed with open vascular repair via primary anastomosis supplemented with a bovine pericardial patch.

LESSONS
Complete aortic wall penetration from an excessively long thoracic pedicle screw with otherwise stable screw positioning may be addressed most effectively with a single anterior surgical approach for open aortic repair and screw tip burring.

Background: Aging is a process caused by oxidants and aging-related enzymes. Therefore, the inhibition of these processes can exacerbate anti-aging agents. This study aimed to evaluate the antioxidant and anti-aging activities of leaf extracts from seven herbs used in traditional Thai herbal remedies. Methods: Researchers assessed the total levels of phenolic content (TPC), antioxidant, anti-collagenase, and anti-tyrosinase activity using colorimetric methods. Cytotoxicity effects were determined using MTT assays, and matrix metalloproteinases(MMPs) secretion was assessed through gelatin zymography. In addition, inhibitory effects on the growth of microorganisms were examined using the disc diffusion and broth microdilution method.Results: TPC ranged between 48.68–440.91 mg GAE/g of ethanolic leaf extracts. High antioxidant activities against ABTS radicals were detected in P. granatum, P. emblica, P. guajava, T. bellirica, and T. chebula, while high DPPH neutralization appeared in M. coreia, P. guajava, and P. granatum. FRAP assays significantly reduced the power of T. chebula and P. granatum. T. chebula and P. guajava exhibited the highest inhibitory effect on H2O2induced ROS production. P. emblica, P. guajava, T. bellirica, and E. hygrophilus reduced tyrosinase and collagenase activities. P. gaujava, T. chebula, and T. bellirica were shown to inhibit the secretion of MMP-2 from fibroblast cells. All concentrations of leaf extracts were non-toxic to fibroblast cells. P.granatum and T. bellirica could inhibit the growth of P. acnes, E. coli, and S. aureus. Conclusion: Preliminary studies showed that P.granatum and T. bellirica leaf extracts have antioxidants, anti-aging, and anti-bacterial activities, as well as active ingredients suitable for cosmetic products.Keywords: antioxidants, anti-aging, leaf extracts
Barriers to implementing Sustainable Tourism Policy in Mass Tourism Destinations
Authors: Dodds Rachel , Butler Richard W. 
Published: February 2023

<p> The focus of this paper is on identifying the barriers to successful implementation of sustainable tourism policy. The research used exploratory and descriptive approaches to identify barriers from the literature as well as field research to determine perceived barriers from key respondents in two specific locations in the Mediterranean- Malta and Calviá. The research found that although respondents were aware of sustainable tourism, the individual advantage from exploiting shared pooled or shared resources is often perceived as being greater than the potential long-term shared losses that result from the deterioration of such resources, which means that there is little motivation for individual actors (whether governments, elected officials, or individual operators), to invest or engage in protection or conservation for more sustainable tourism. </p>
