Published: November 2020

Background:

Meningiomas are common central nervous system neoplasms, accounts for 30% of all primary intracranial neoplasms; the occurrence of meningiomas with cystic lesions is an exceptionally rare. Lymphoplasmacyte-rich meningioma (LPRM) is a rare pathological entity belong to the World Health Organization Grade I meningiomas. LPRM is characterized by abundant lymphoplasmacytic infiltrates which over-shadow the underlying meningothelial component.

Case Description:

A 42-year-old male was admitted to our hospital with a chronic headache for about 3 weeks prior to admission. His symptoms worsen, and subsequently, he experienced left extremities weakness about 1 week before admission. His brain magnetic resonance imaging revealed an irregular and heterogeneously enhancing solid lesion with intratumoral cystic changes at the temporal lobe. A gross total resection was performed; pathological examination revealed a cystic LPRM.

Conclusion:

This rare variant of meningioma is a benign tumor entity featured with massive inflammatory cell infiltration and often less proportion of meningothelial elements. Surgical resection remains the treatment of choice. This is the first report regarding cystic LPRM from Indonesia; we also summarized relevant literature upto-date, May 2020, reported LPRM cases.

Authors: Yang Tae-yeong , Shin Sung Hee
Published: November 2020

The use of prophylactic dressings to help prevent intraoperatively acquired pressure injuries (IAPIs) merits further study. PURPOSE: To examine how the use of a soft silicone foam dressing affects the development of IAPIs in patients undergoing spinal surgery to obtain baseline data supporting evidence-based nursing care. METHODS: Using a self-controlled study design, 64 patients requiring thoracic or lumbar surgery on a Wilson frame at a hospital in Seoul, South Korea, were recruited between February 12 and September 1, 2018; 50 patients were eligible. Basic demographic, health, and surgical data were obtained. Before surgery, the left or right side chest and iliac crest areas were randomly assigned to be covered with a soft silicone foam dressing. The areas were assessed at 2 time points: immediately after and 30 minutes after surgery. If an IAPI was present at 30 minutes after surgery, all sites were reevaluated after 7 days. RESULTS: The majority of participants were male (26 participants, 52%). Average patient age was 62.54 (± 13.83) years, with a body mass index of 24.32 (± 4.23) kg/m2. Average length of surgery was 218.4 (± 137) minutes. Immediately after surgery, 26 IAPIs were observed and there was a significant difference between dressed and non-dressed chest areas for the number of IAPIs (4% vs. 28%; P = .002). After 30 minutes, the total number of IAPIs was 20 and the difference between IAPIs in the iliac crest area was significant between dressed and non-dressed areas (0% vs. 14%; P = .012). After 1 week, there were no chest or iliac crest IAPIs in the areas that had been covered by a dressing; however, 8 chest (61.5%) and 4 iliac crest (30.8%) area IAPIs remained when no dressing had been applied. The majority of IAPIs were stage 1 at all assessment times. After 1 week, 1 IAPI had evolved into a stage 3 injury. CONCLUSIONS: The results of this study show that many stage 1 IAPIs do resolve over time and that use of soft silicone foam dressings during spinal surgery can significantly reduce IAPI rates. Additional longitudinal studies are needed to help guide postoperative skin assessment intervals and increase the understanding about the evolution of stage 1 IAPIs.

Authors: Adrogué Cecilia
Published: November 2020

The educational sector has assumed long time ago the challenge of incorporating technologies into teaching and learning processes. And secondary school plays an essential role in the development of the necessary capacities for intelligent and critical understanding and usage of the new languages produced in the field of information technologies. The objective of this work is to analyze the access to ICT at students’ home and at school, using the microdata of the 2016 Learning Census for seniors in high school and to show the inequalities observed by province, type of school management and socioeconomic level of the student. Among the main conclusions found, the following can be mentioned: at the national level, approximately 40% of the students say they have a computer at home; there are great disparities among them, since less than 14% of those with lower socioeconomic status say they have, while more than 72% of students with highest income say so. However more than 70% of all students –both low and high socioeconomic level– say they use computer at school at least a few times a year. The results show that there are no differences by socioeconomic level of the students in the activities proposed by teachers to do with computers during class time.

We demonstrate the feasibility of using a combination of alkali atoms (Na and K) to develop a robust mixed-alkali honeycomb layered oxide NaKNi2TeO6. Through a series of atomic-resolution transmission electron microscopy in multiple zone axes, we reveal for the first time the local atomic structural disorders characterised by aperiodic stackings and incoherency in the alternating arrangement of Na and K atoms. Our findings indicate great structural versatility that renders NaKNi2TeO6 an ideal platform for investigating other fascinating properties such as mixed ionic transport and intriguing electromagnetic and quantum phenomena amongst honeycomb layered oxides. Finally, we unveil the possibility of inducing mixed Na- and K-ion transport electrochemistry of NaKNi2TeO6 at high voltages (~ 4V), thus epitomising it as a competent cathode candidate for the emerging dendrite-free batteries based on NaK liquid metal alloy as anodes. The results not only betoken a new avenue for developing functional materials with fascinating crystal versatility, but also prefigure a new age of ‘dendrite-free’ energy storage system designs that rely on mixed-cation electrochemistry.

Published: November 2020

Introduction: In 2017, the School of Medicine of the University of Notre Dame Australia implemented a data-informed mentoring program as part of a more substantial shift towards programmatic assessment. Data-informed mentoring, in an educational context, can be challenging with boundaries between mentor, coach and assessor roles sometimes blurred. Mentors may be required to concurrently develop trust relationships, guide learning and development, and assess student performance. The place of data-informed mentoring within an overall assessment design can also be ambiguous. This paper is a preliminary evaluation study of the implementation of data informed mentoring at a medical school, focusing specifically on how students and staff reacted and responded to the initiative.
Methods: Action research framed and guided the conduct of the research. Mixed methods, involving qualitative and quantitative tools, were used with data collected from students through questionnaires and mentors through focus groups.
Results: Both students and mentors appreciated data-informed mentoring and indications are that it is an effective augmentation to the School’s educational program, serving as a useful step towards the implementation of programmatic assessment.
Conclusion: Although data-informed mentoring is valued by students and mentors, more work is required to: better integrate it with assessment policies and practices; stimulate students’ intrinsic motivation; improve task design and feedback processes; develop consistent learner-centred approaches to mentoring; and support data-informed mentoring with appropriate information and communications technologies. The initiative is described using an ecological model that may be useful to organisations considering data-informed mentoring.
HAPPE—A pilot programme using humanities to teach junior doctors empathy in a palliative medicine posting
Authors: Ong Eng Koon
Published: November 2020

Introduction: Physician empathy is declining due to an unproportionate focus on technical knowledge and skills. The medical humanities can counter this by allowing connection with our patients. This is a pilot study that aims to investigate the acceptability, efficacy, and feasibility of a humanities educational intervention to develop physician empathy. Methods: Junior doctors at the Division of Supportive and Palliative Care at the National Cancer Centre Singapore between July 2018 and June 2019 attended two small-group sessions facilitated by psychologists to learn about empathy using literature and other arts-based materials. Feasibility was defined as a completion rate of at least 80% while acceptability was assessed by a 5-question Likert-scale questionnaire. Empathy was measured pre- and post-intervention using Jefferson’s Scale of Physician Empathy (JSPE) and the modified-CARE (Consultation and Relational Empathy) measure. Results: Seventeen participants consented, and all completed the programme. Acceptability scores ranged from 18 to 50 out of 50 (mean 38, median 38). There was an increase in JSPE scores (pre-test mean 103.6, SD=11.0 and post-test mean 108.9, SD=9.9; t (17) =2.49, P=.02). The modified-CARE score increased between pre-test mean of 22.9(SD=5.8) and a post-test mean of 28.5(SD=5.9); t (17) = 5.22, P<0.001. Conclusion: Results indicate that the programme was acceptable, effective, and feasible. The results are limited by the lack of longitudinal follow-up. Future studies that investigate the programme’s effect over time and qualitative analysis can better assess its efficacy and elicit the participants' experiences for future implementation and refinement.
Are the values valued in healthcare?
Authors: Sinnathamby Annushkha Sharanya
Published: November 2020

“To have striven, to have made the effort, to have been true to certain ideals - this alone is worth the struggle.” William Osler The word “values” is heard frequently in healthcare. From the moment we step into medical school, we are challenged to reflect what our intrinsic values are, or how we can “add value” to a department during the residency application. With time, and in going through the system, our definitions of the word “values” may change. To me, values are those things which are right and wrong, and which are important in life. In other words, values include not only what is important to my profession and to being a good doctor, but also to what is important to being a good person.
Fit-For-Purpose History Matching Approach for A Low-Quality Reservoir Under Waterflood: Integration of Uncertain Production Allocation
Authors: Syafwan M.
Published: November 2020

This paper presents a fit-for-purpose approach to mitigate zonal production data allocation uncertainty during history matching of a reservoir simulation model due to limited production logging data. To avoid propagating perforation/production zone allocation uncertainty at commingled wells into the history matched reservoir model, only well-level production data from historical periods when production was from a single zone were used to calibrate reservoir properties that determine initial volumetric. Then, during periods of the history with commingled production, average reservoir pressure measurements were integrated into the model to allocate fluid production to the target reservoir. Last, the periods constrained by dedicated well-level fluid production and average reservoir pressure were merged over the forty-eight-year history to construct a single history matched reservoir model in preparation for waterflood performance forecasting. This innovative history matching approach, which mitigates the impacts of production allocation uncertainty by using different intervals of the historical data to calibrate model saturations and model pressures, has provided a new interpretation of OOIP and current recovery factor, as well as drive mechanisms including aquifer strength and capillary pressure. Fluid allocation from the target reservoir in the history matched model is 85% lower than previously estimated. The history matched model was used as a quantitative forecasting and optimization tool to expand the recent waterflood with improved production forecast reliability. The remaining mobile oil saturation map and streamline-based waterflood diagnostics have improved understanding of injector-producer connectivity and swept pore volumes, e.g., current swept volumes are minor and well-centric with limited indication of breakthrough at adjacent producers resulting in high remaining mobile oil saturation. Accordingly, the history matched model provides a foundation to select new injection points, determine dedicated producer locations and support optimized injection strategies to improve recovery.
Evidences and New Method to Solve Tortuosity Problem of Hydraulic Fracturing Job in The Rokan Block
Authors: Trisnadi M.
Published: November 2020

This paper is intended to present an investigation of a hydraulic fracturing problem in the small fields of the Rokan Block asset. In order to optimize the oil production, the Operator undertook a hydraulic fracturing campaign in the small fields. Since based on historical results it needed high efforts in breaking the reservoir, during 2018 to 2019 almost half of the campaigns were postponed. The authors attempted to figure out a solution in fracturing the reservoir by implementing some of the common options utilized in the oil and gas industry (such as continuous pumping, acidizing, and re-perforate with big hole gun), and ultimately the reservoir fractured with hesitation pumping, which is a new method to break the formation, where repetition pumping performed to the maximum surface pressure limitation (hammering effect). The pre and post-frac fall-off pressure through G-function analysis indicated a Tortuosity effect. Compiling several historical hydraulic fracturing data of typical sands are required to have better understanding of reservoir issues by interpreting fall-off pressure data from mini fracturing through G-Function and Post Closure Analysis. Through these analyses, typical cases with near wellbore pressure loss (NWBPL) can be examined by performing output data matching with the reservoir properties, and it is also useful in fine tuning fracture treatment designs and execution. Furthermore, possible methods to resolve the NWBPL issue were listed, and then an experiment is carried out to determine which method is the most effective effort. In this study, the authors also carried out hydraulic fracturing operational lookback to differentiate jobs performed in the past, whether dominated by tortuosity issue or perforation friction, and to identify what effective proactive efforts were made. Moreover, the authors provide a comparison of several proactive efforts’ effectiveness: re-perf with big hole gun, acidizing and hesitation pumping. Based on those experiments, the authors conclude that the hesitation pumping effort is a new method that has proven to be effective in resolving the issue, and is even better than two other methods in term of the impact and the cost spending.
Banyu Urip Upper Perforation Shut-off: A Success Story of Hydroformed Expandable Casing Patch Installation to Reduce GOR and Maximize Oil Production
Authors: Saputra D.
Published: November 2020

ExxonMobil Cepu Limited (EMCL), as the operator of Banyu Urip field in Cepu Block, Indonesia, observed several oil wells with high Gas Oil Ratio (GOR) after several years of production. Oil production curtailment was expected due to limited surface gas handling capacity. Additional stand-off against reservoir gas cap shall be established by performing top perforation interval shut-off to reduce GOR and maximize oil production. Perforation shut-off became more challenging due to high concentrations of H2S and CO2, relatively high reservoir temperature, long perforation interval, and total losses experience. The remedial solution required a V0 “gas-tight” qualification, live well execution, induced minimum to no formation damage, and provided minimum reduction of tubular Inner Diameter (ID) post remedial work to avoid significant production impact and allow future wireline tools deployment. Considering the high profile of Banyu Urip field, which currently produces ~29% of Indonesia’s oil production, EMCL selected the fit-for-purpose remedial method with the highest probability of success. The hydroformed expandable casing patch (patch) with Corrosion Resistance Alloy (CRA) material and its top-down expansion method was evaluated and selected. The re-designing of inflatable element was performed to improve durability in high temperature and verified by laboratory testing. Patches were installed and overlapped to cover the top perforation interval. Seals on top and bottom of the patch extremities formed V0 “gas-tight” sealing mechanism against the casing. The patches were deployed utilizing a smart coiled tubing. All patches were successfully installed as per plan. The wells were brought online with significantly reduced GOR post patches installation. This was the first installation of the patch utilizing smart coiled tubing and ~90 feet Coiled Tubing (CT) tower in sour wells within any ExxonMobil affiliates. The detailed technical preparation, strong safety culture and leadership as well as relentless learnings application have delivered a successful project to reduce Banyu Urip wells GOR and enable EMCL to maximize oil production.
Chemistry Review of Vaping Products and Respiratory Injury
Authors: Lau Chester , Zhao Ran , Vethanayagam Dilini
Published: November 2020

Background: While the Public Health Agency of Canada notes 19 cases from May 2019 to February 2020 relating to e-cigarette or vaping product use-associated lung injury (EVALI) in Canada, there are likely many more unreported cases, including non-hospitalized and asymptomatic cases. E-cigarette use or vaping exposes users to numerous aerosolized chemical species, some of which have proven to be deleterious to health. These chemical species can include vitamin E acetate (VEA), flavourants, base / solvents (propylene glycol or vegetable glycerin), psychoactive substances, pesticides, endotoxins, metals, and pyrolysis by-products from e-cigarette heating coils.
Objectives: We aim to review current findings related to EVALI from the standpoint of known chemical species currently used in vaping products. We specifically examine the toxicological profiles of these chemical species and the mechanisms through which they cause lung injury.
Methods: A comprehensive literature search was performed with MEDLINE for EVALI-related human studies that were published between January 1, 2010, and May 15, 2020. This search strategy identified 832 case reports, case series, clinical trials, and in-vitro laboratory studies. From this group, 71 records were examined in greater detail.
Results and Conclusions: Although the chemical composition and toxicology of vaping products have largely been characterized, the physiological effects of the chemical interactions between various constituents of vaping products and the generation of new species remain inconclusive. Given the rapid increase in the popularity of vaping and e-cigarettes, there is a need for further research. Developing a comprehensive understanding of the chronic health effects of vaping through randomized controlled trials and physiological studies is prudent and necessary to reduce the long-term impacts on users and the health care system.

Published: November 2020

Communicative competence underlines that grammatical knowledge is not enough to interact adequately, and thus includes pragmatic skills. For example, several communication errors, for confusion, may take place without logical understanding. Furthermore, politeness is an essential component of pragmatic competence. Many work has been carried out in this area, but few have shown the differences between the linguistic politeness of the language of male and female in the speaking classroom, while its primary findings are statements. Such work is carried out in the speaking classroom of university students, in particular in the sense of global foreign affairs. The statement is based on the Bacha, Bahous & Diab (2012) translation from DCT. In addition, certain politeness hypotheses are used to interpret the results. The studies have shown that women are more respectful than male students in general. Finally, teachers will comprehend this reality since they do not require male students to be as respectful as girls, they are practically peculiar.

Published: November 2020

The industrial revolution and the free market policy agreement among the countries in the world brings severe impacts in many sectors, especially economics. As one of the supporting economics systems, the banking sector also faces the most significant challenge ever. The banks should provide their best services to the customers; otherwise, they will quickly leave them. This study determines how the front-liners’ (Customer Services and Tellers) can speak English to support their workplace activities. There are ten customer services and eight tellers from four banks as the respondents. The method used is quantitative, with a structured interview as the instrument to collect data. The researcher then measured the result of the talks by using a scoring rubric. The study's development reveals that those front-liners have different English proficiency levels, ranging from high to low. The banks where they work and the universities where they learned are responsible for overcoming this. It could be by restricting the new employee's entrance exam, providing training programs for the employees, and updating the universities' curriculum with the latest material to prepare their students to face the job market, which is very demanding today.

Nesfatin-1 is a newly found food and water intake regulatory neuropeptide. Because it can regulate nutrition and thirst, nesfatin-1 may also have the potential to affect levels of blood electrolytes and metabolites. The current study was intended to resolve the acute influence of intracerebroventricularly injected nesfatin-1 on the levels of some blood electrolytes and metabolites in rats.

The experiments were conducted on Sprague Dawley male rats. Nesfatin-1 (200 pmol) or saline (5 μL) was given the rats intracerebroventricularly. Central nesfatin-1 treatment caused increases in the concentrations of blood glucose, lactate, hematocrit, and hemoglobin without changing the blood pH, creatine, Na, K, Ca, Cl, and HCO3 levels.

In conclusion, our findings show that the central nesfatin-1 could affect the concentrations of blood glucose, lactate, hematocrit, and hemoglobin without altering the blood electrolytes. This could be interpreted as the secondary effect of nesfatin-1 as a consequence of centrally injected nesfatin-1-evoked activation of sympathetic nerves.
Lexical typological approach to prefix derivatives: verbs of falling with the prefixes *o-/obin Russian, Serbian and Slovenian

The paper presents a novel approach to a typologically oriented semantic analysis of Slavic prefixes exemplified with the data of Russian, Serbian and Slovenian verbs of falling with the prefixes *o-/ob-. Based on dictionary and corpus data supplemented by native speakers surveys we scrutinize distributional properties of the verbs of falling with the prefixes *o-/ob- and form a list of their meanings expressed in different contexts. We show that Russian and Serbian cognates cover one and the same conceptual space, but the verbs partition it in different ways, i.e. the differences between Russian and Serbian within this semantic domain are mostly due to semantic properties of the verbal roots, while the prefixes exhibit a similar linguistic behavior. In Serbian, unlike Russian, the root -val- is not used in the domain of falling, and the Serbian root -padcovers almost all the situations, in which -syp- is used in Russian. Thus, cognates are not semantically equivalent to each other, for instance, the Serbian verb osuti se corresponds to Russian verbs obsypat’sya and obrushit’sya rather than to its direct cognate osypat’sya. In Slovenian, the system of the verbal roots with the meaning of falling is very close to the Serbian one (the root -val- is not present, -pad- is used broader), while the semantics of the prefixes changes: the prefixes od-, z- and u- drive out o-/ob- in different subzones of the conceptual space. We visualize these tendencies with a semantic map, which allows to map both roots and prefixes without any violation of the Semantic Map Connectivity Hypothesis (every linguistic means covers a connected region on a map). We also demonstrate that the verbs covering the same points on the map, and not the cognates as one could expect, develop the same metaphoric extensions. For example, the metaphor of the decrease («Less is Down») is conveyed by the Serbian verb opasti and the Slovenian verb upasti, which both denote literal level recession
Lexical typology through learner corpora: semantic domain of falling
Authors:   Higher School of Economics, Vyrenkova A.
Published: November 2020

This paper investigates the use of the Russian verb padat’ ‘to fall’ and its quasi-synonyms. Padat’ is dominant in the system of Russian predicates of falling —and therefore should be suitable for describing any type of uncontrolled downward motion. However, in a number of contexts a diff erent means of expression is required. These contexts are not easily detected because they normally render the meanings which are peripheral in the semantic domain of falling. In this study, we attempt to fi nd such contexts with the help of the Russian Learner Corpus, which contains texts produced by heritage speakers and learners of Russian with various dominant languages. The corpus enables search by error tags and gives valuable data for the analysis of learners’ interlanguage. Lexical and grammatical violations found in the free production of foreign learners of Russian are used to uncover cases where the dominant verb padat’ ‘to fall’ yields to its quasi-synonymous counterparts. In this paper we are aiming at detecting specific limitations in the distribution of the dominant lexeme and, based on the data coming from the Russian Learner Corpus (for this study examples from learners dominant in English and Korean are taken), we focus on the initial point of the falling motion, precipitation subframe and aspectual characteristics of the dominant verb upast’ and its quasi-synonym vypast’. The latter issue is investigated through the scope effect that the verbs of falling demonstrate in combination with the Russian proximative adverb počti ‘almost’. For each case we give a possible explanation of the learner’s error and make an attempt to establish the rules of standard Russian that make the use of the dominant lexeme unacceptable. The results of the study significantly contribute to typological analysis of dominant systems across languages and have implications for synchronic and diachronic studies of domain lexemes.
Effect of Anisaldehyde as Corrosion Inhibitor for Aluminium in Sulphuric Acid Solution

Published: November 2020

The inhibition effect of anisaldehyde on the corrosion of aluminium in sulphuric acid was investigated by weight loss method and characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) analyses. The effect of different inhibitor concentrations was studied at varying temperature (308, 313 and 318 K). It was found that the percentage of inhibition efficiency (% I.E.) increases with increase of inhibitor concentration and decreases with increase in temperature. The values of activation energy and half-life were found to be higher in inhibited acid solution compared to uninhibited acid solution, while that for the rate constant reduced from uninhibited to inhibited acid solution. The negative values of Gibbs free energy of adsorption confirmed the spontaneity of the process. Other thermodynamic parameters such as enthalpy and entropy were also evaluated and discussed. The investigation of adsorption isotherm model indicates that the inhibitor fitted to Langmuir isotherm model. Result of SEM analysis shows how the inhibitor reduced the acid attack on the aluminium surface, and FTIR analysis result of the corrosion product proves the formation of thin layer of inhibitor molecules on aluminium surface.

Neste artigo, refletimos sobre o jornalismo e a necessidade de se reformular as relações deste com suas próprias narrativas de certeza. Traçamos um caminho pelos estudos de jornalismo e os de narrativa, trazendo o exemplo sobre as manchas de óleo que apareceram nas praias do litoral do nordeste brasileiro, em 2019. Essas narrativas de incerteza e imprecisão constroem espaços fluidos nos quais pensamos o lugar de privilégio que o jornalismo – mediador e narrador do mundo – construiu para si, e o quanto os que se dedicam a analisar suas narrativas também precisam repensar esses caminhos de idealizações.
