Authors: Mehra Neha , Makker Robina , Khanna Abhishek 
Published: November 2020

Increased sympathoadrenal activity invariably occurs during endotracheal intubation. Various drugs have been used to obtund this pressor response. This study was done to find out most favourable drug among fentanyl, nalbuphine and clonidine for prevention of this pressor response.This was a randomized, prospective study involving ninety patients of ASA grade 1, equally divided into three groups. Group F, C and N received fentanyl 2 mcg /kg, Clonidine 2 mcg/kg and nalbuphine 2mg/kg i.v respectively, 5 minutes prior to induction. Vitals parameters were noted at frequent intervals Chi square test and Anova test were used for statistical analysis. P value &#60;0.05 was considered as statistically significant.Maximum increase in heart rate and blood pressure was seen at the time of intubation in F and N groups, whereas decrease in these parameters occured with clonIdine, difference was found to be stastistically significant. Haemodynamic stability was seen in F and N group after 5 minutes of intubation. Clonidine showed maximum decrease in heart rate and systolic as well as diastolic blood pressure at all time intervals from intubation as compared to other two groups.In this study it was found that Clonidine produced an earlier and more stable haemodynamics as compared to Fentanyl and Nalbuphine, and it can be concluded that Clonidine given intravenously in doses of 2 mcg/kg 5 minutes prior to intubation is superior to Fentanyl and Nalbuphine in preventing heamodynamic changes at the time of laryngoscopy and intubation.
De la insubordinación a la cooptación: el sindicato petrolero y las movilizaciones de 1958 y 1959
Authors: Zarauz López Héctor Luis 
Published: November 2020

Los objetivos del artículo son reconstruir la movilización de los petroleros en los años de 1958 y 1959; observar las demandas y estrategias de lucha y, finalmente, observar las tácticas del gobierno para mantener el control sobre este sindicato. En el desarrollo del trabajo se logra documentar las movilizaciones de los trabajadores petroleros en la ciudad de México en los años de 1958 y 1959, así como sus antecedentes. Se observan las causas y formas de lucha y su asociación con otros sectores sociales, así como las estrategias de cooptación ejercidas por el gobierno mexicano. De esto se concluye que, a diferencia de otros movimientos, los petroleros recibieron un trato diferente por parte del gobierno. Esto, sumado a una estrategia de negociación, permitió que los líderes opositores se unieran al sistema sindical oficial. Todo lo anterior en un ambiente de enorme protesta social, liderado por los sindicatos afiliados al propio gobierno. El movimiento de los petroleros en estos años no ha sido estudiado; en general, los trabajos sobre sindicalismo de este periodo se centran en las protestas de profesores y ferrocarrileros, así como en las acciones de las centrales oficiales. Este trabajo fue construido, principalmente, con base en fuentes de primera mano.
“Yo maté y vi torturar”: declaraciones públicas de un represor en la transición argentina (1984)
Authors: Feld Claudia 
Published: November 2020

Este artículo analiza las declaraciones del excabo de la Armada Raúl Vilariño acerca de los crímenes presenciados y cometidos por él mismo durante la dictadura militar argentina (1976-1983). Publicadas en una revista de circulación masiva en 1984, estas declaraciones permiten examinar los modos en que se intenta construir la figura del perpetrador en los primeros meses de la transición política en Argentina. El artículo aborda: a) el lenguaje y punto de vista con los que Vilariño se refirió a los hechos; b) el “dispositivo de visibilidad” (Rancière) para representar a Vilariño en tanto responsable y testigo de los crímenes; c) el impacto inmediato de estas declaraciones y sus vínculos con la “verdad fáctica” y la “verdad social” acerca del terrorismo de Estado, y d) las nociones de justicia en pugna en ese momento. Los resultados de esta investigación permiten entender la transición como periodo en que las fronteras de lo decible estaban en revisión, en que el punto de vista “crudo” del represor era socialmente aceptable y en que las pugnas por entender la masividad y excepcionalidad de la desaparición forzada tenían todavía un final incierto.

Published: November 2020

<span>This article deals with the relationship existing between the emotional aspect and decision-making processes. More specifically, it examines the links between emotional Intelligence and the ownership concentration. I will use logistic binary regression ) to examine this relation: every model treats the relationship between emotional intelligence and one of efficiency criteria of the ownership structure. Emotional intelligence has been measured according to the scale of Schutte and al (Shutte Self Report Emotional Intelligence Scale, SSREI, Shuttle and al. 1998) with a high internal validity level. Regarding, The four cognitive biases they have been measured by means of a questionnaire comprising several items. As for the selected sample, it has been composed of some180 Tunisian executives (belonging to 60 firms). Our results have revealed that the presence of a high emotional intelligence rate is not always positively correlated with the executives’ suggestibility with respect to behavioural biases. They have also affirmed the existence of Substitutability between emotional intelligence and the Ownership structure disciplinary function</span>

Published: November 2020

In this digital era, all activities can be published to the public through social media. Many groups of people actively use social media ranging from students, adults, entrepreneurs and state officials. One of them is the seventh President of the Republic of Indonesia, Ir. H. Joko Widodo. Joko Widodo has a variety of social media platforms, social media with the most followers among other social media is Instagram. With a total of 16.5 million followers making him the leader of the country with the second most followers in the world. The content of uploads on Instagram of Joko Widodo is diverse and very massive, the things Joko Widodo does on Instagram social media is one way to form personal branding. Personal branding is a unique phenomenon because basically all people have their own characteristics, to get the results of long-lasting branding and provide maximum benefits, the branding process must come from authentic, real and original evidence. This study aims to determine how effective the use of social media instagram is for the formation of Joko Widodo's personal Branding to the 2019 First Election Voters who are still confused and need references to make choices in using their voting rights. This study uses a descriptive quantitative method of two variables. The independent variable in this study is the effectiveness of using social media instagram while the dependent variable is Joko Widodo's personal branding. This research was conducted by distributing questionnaires to 100 respondents using the Nonprobality Sampling technique. The results of this study state that the use of Instagram social media in delivering the desired message falls into the effective category with a percentage of 74.9% while the formation of personal branding for the first voters is included in the effective category with a percentage of 81.1%. The conclusion of this study is that the communication carried out by Joko Widodo's Instagram social media account took place effectively and had a positive effect on the formation of Joko Widodo's personal branding for the first voters of the 2019 Election.

ABSTRACT
Every nation in the world struggles as globalization comes obscuring borders between each of them, pushing their society to accept the diversity of cultures and any consequences that comes from it. Intercultural communication competence which stems from the awareness of different cultures is now to be expected for every individual that strive to go forward with the advancement of communication technology that blurs the line even more. As such, this study aims to explain on how an exchange programme can build the intercultural awareness towards its participants that will increase the intercultural communication competence in the future, which focuses on the Global Citizen Programme hold by AIESEC Purwokerto. This study uses qualitative approach with in-depth interview and literature review as the method to collect the data. This study uses purposive sampling on the six informants who once became the exchange participant to Vietnam, Thailand (two participants), Czech, Slovakia, and Ukraine. The results show that the exchange programme can raise intercultural awareness through international exposure that comes from the experience facing differences in culture, mindset, behaviour, and the level of language proficiency. The experience can help participants to increase their ability to adapt and to be more flexible, and can appreciate different values without judging them firsthand which leads to empathy. Since Intercultural awareness is a condition when an individual does not show the rejection towards new things they are facing, the participants therefore have already reached the level of acceptance.

Preoperative Skin Cultures Predict Periprosthetic Infections in Revised Shoulder Arthroplasties
Authors: Matsen Frederick A. , Whitson Anastasia , Hsu Jason E. 
Published: November 2020

Background:
Current approaches do not provide a practical method for the accurate prediction of a Cutibacterium periprosthetic joint infection (PJI) in failed arthroplasties. Thus, surgeons revising failed arthroplasties must decide whether to exchange the implants and to institute antibiotic treatment without knowing the results of cultures of deep specimens obtained at the revision procedure. This study tests the hypothesis that the results of preoperative culture specimens of the skin surface obtained in the clinic can predict the presence of culture-positive Cutibacterium PJIs.

Methods:
Revision shoulder arthroplasties performed between October 3, 2017, and February 4, 2020, that had both preoperative clinic culture specimens and surgical culture specimens were included in this analysis. Culture results were assigned a value from 0 to 4. The percentage of the total skin bacterial load contributed by Cutibacterium (Cutibacterium percentage) was determined. To reduce concern about contamination, a robust criterion for culture-positive Cutibacterium PJI was applied: ≥2 surgical specimens with a Cutibacterium value of ≥1. The predictive values for a culture-positive Cutibacterium PJI were determined for a clinic skin culture Cutibacterium value of >1 and a clinic skin percentage of Cutibacterium of ≥75%.

Results:
Eighteen cases met the inclusion criteria; of these, 7 (6 male patients) met our criterion for a culture-positive Cutibacterium PJI. For all patients, a preoperative clinic skin Cutibacterium value of >1 predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 89%, and a clinic skin Cutibacterium percentage of ≥75% predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 94%. For male patients, a preoperative clinic skin Cutibacterium value of >1 predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 91%, and a clinic skin Cutibacterium percentage of ≥75% predicted the presence of a culture-positive Cutibacterium PJI with an accuracy of 100%.

Conclusions:
A simple culture specimen of the unprepared skin surface obtained in a clinic prior to revision shoulder arthroplasty may provide valuable assistance to surgeons planning a revision arthroplasty.

Technology Focus: Gas Production (November 2020)
Authors: Wilson Scott J. 
Published: November 2020

When two black swans - weak industry fundamentals and a global pandemic - collided midair, a downward spiral became a freefall. Accompanied by the human tragedy of illness and financial hardship, industry employment shrunk at a pace not seen since 1986 and caused a contraction to the lowest international rig count since Baker Hughes started keeping records 43 years ago.
How has this upheaval affected the demand for the natural gas our industry supplies? Not very much.
Essential goods and services rose to the top of our attention in 2020, and natural gas has proved to be essential and reliable. Gas-fired electricity usage actually increased as stay-at-home orders nullified the economies of scale provided by shared workspaces. Natural-gas-powered delivery trucks bring things to us as we avoid crowded stores. While office buildings are kept cool or warm for a small number of onsite workers, work-from-home employees now demand a comfortable home 24 hours a day rather than just evenings and weekends. Worldwide demand is marginally lower because of curtailed economic activity, but that decline has been matched by the decrease in associated gas from shut-in oil wells.
While the selected papers were written before these developments, they each show the spirit of innovation and dedication to improving processes that will be required to rebound fully and continue to deliver the energy our world needs. Engineers thrive on making more from less, and this month’s paper selections highlight efforts to improve the efficiency of gas-production operations throughout the world.
Natural-gas suppliers continue to provide uninterrupted service despite fewer people and smaller budgets. Like other essential workers, they are heroes and deserve our sincerest thanks.

Pseudoslug flow does not comply with the basic characteristics of conventional unit-cell slug flow. The liquid in the pseudoslug body is insufficient to reach the upper part of the pipe wall, resulting in only a large wave with entrained gas bubbles at the bottom part of the pseudoslug body. The pseudoslug body can be divided into two regions, liquid film (wave) with entrained gas bubbles at the bottom and gas core with entrained liquid droplets. The complete paper develops a plausible physical model of the experimentally observed pseudoslug liquid-holdup phenomenon and models physical and hydrodynamic behavior using a dimensional regression modeling approach.
Short-Term Production Optimization Under Water-Cut Uncertainty

Published: November 2020

Summary
Short-term production optimization is an essential activity in the oil/gasfield-development process because it allows for the maximization of field production by finding the optimal operational point. In the fields that use gas lift as an artificial-lift method, the gas-lift optimization is a short-term problem. This paper presents a stochastic approach to include uncertainties from production parameters in gas-lift optimization, called the uncertain-gas-lift-optimization problem (UGLOP). Uncertainties from production variables are originated from the measurement process and the intrinsic stochastic phenomena of the production activity. The production variables usually obtained from production tests play an important role in the optimization process because they are used to update reservoir and well models. To include the uncertainties, the strategy involves representing the well-test data using nonlinear regression [support-vector regression (SVR)] and using the Latin-hypercube-sampling (LHS) method. The optimization gives a stochastic solution for the operational point. In the solved problem, this operational point is composed of the individual wells’ gas-lift-injection rate, choke opening, and well/separator routing. The value of the stochastic solution is computed to evaluate the benefit of solving the stochastic problem over the deterministic. The developed methodology is applied to wells of a Brazilian field considering uncertainty in water-cut (WC) values. As a result, an up-to-4.5% gain in oil production is observed using this approach.
Dynamic Contact Angle Reformulates Pore-Scale Fluid-Fluid Displacement at Ultralow Interfacial Tension

Published: November 2020

Summary
Surfactant flooding is an effective enhanced oil recovery method in which the oil/water interfacial tension (IFT) is reduced to ultralow values (&lt;0.01 mN/m). The microscopic fluid-fluid displacement has been extensively studied at high IFT (&gt;10 mN/m). However, the microscopic displacement dynamics can be significantly different when the IFT is ultralow because the dynamic contact angle increases with the increase of the capillary number. In this study, surfactant flooding was performed and visualized in micromodels to investigate the dynamics of multiphase displacement at ultralow IFT. Although the micromodels used were strongly water-wet, the displacements of oil by surfactant solutions at ultralow IFT appeared as drainage. Furthermore, a macroscopic oil film was left behind on the surface, which indicates that a contact line instability occurred during displacements. The shape of the oil/water meniscus was determined by the balance between viscous forces and capillary forces. The meniscus can be significantly distorted by viscous forces at ultralow IFT. Therefore, the water-wet micromodel exhibits an oil-wet behavior at ultralow IFT, and the displacements of oil by surfactant solutions at ultralow IFT manifested as drainage rather than imbibition. The flow behavior is further complicated by the spontaneous formation of microemulsion during displacement. The microemulsion is mainly formed from the residual oil. The formation of a microemulsion bank made the surfactant solution discontinuous, with transport in the form of droplets in the microemulsion bank and displacement front. The novelty of this work is to reveal the effects of dynamic contact angle on the ultralow IFT displacement.

Abstract
The magnitude and nature of the COVID-19 pandemic prevents public health policies from relying on coercive enforcement. Practicing social distancing, wearing masks and staying at home are voluntary and conditional on the behavior of others. We present the results of a large-scale survey experiment in nine countries with representative samples of the population. We find that both empirical expectations (what others do) and normative expectations (what others approve of) play a significant role in compliance, beyond the effect of any other individual or group characteristic. In our survey experiment, when empirical and normative expectations of individuals are high, compliance goes up by 55% (relative to the low expectations condition). Similar results are obtained when we look at self-reported compliance among those with high expectations. Our results are driven by an asymmetric interaction with individuals’ trust in government and science. Holding both expectations high, the effect of trusting science is substantial and significant in our vignette experiment (22% increase in compliance), and even larger in self-reported compliance (76% and 127% increase before and after the lockdown). By contrast, trusting the government only generates modest effects. At the macro level, the country-level trust in science, and not in government, becomes a strong predictor of compliance.
