Authors: Ortiz Medina Janeth María , Arismendi Gómez Fabio Alberto , Londoño Ceballos Paula Andrea 
Published: September 2022

Este artículo presenta los hallazgos de la implementación de un curso de desarrollo profesional docente, llevado a cabo con 17 profesores de inglés, francés y otras lenguas extranjeras de una universidad pública en Colombia. Su objetivo fue explorar la interculturalidad crítica mediante la promoción de la reflexión en torno a las prácticas de los profesores y la construcción de propuestas de enseñanza más equitativas en sus clases. Esta iniciativa, enmarcada en un estudio cualitativo de investigación-acción, se orientó por las ideas del pensamiento decolonial y la interculturalidad crítica. Los métodos de recolección de datos incluyeron entrevistas, grabaciones de las sesiones del curso, planeaciones de clases de lenguas extranjeras y reflexiones de los participantes. Los hallazgos revelan que los docentes desarrollaron comprensiones de la interculturalidad como un proceso de construcción de equidad, íntimamente ligado a la negociación de identidades y atravesado por relaciones de poder. Estos resultados sugieren que los espacios de desarrollo profesional docente pueden contribuir a la construcción de un proyec­to intercultural propio en el campo de las lenguas extranjeras, que sea respetuoso y consecuente con las realidades, problemáticas y diversidades de los pueblos y territorios colombianos y latinoamericanos, que fortalezca la producción de conocimiento local situado, y que dialogue con conocimientos de otras latitudes.

Published: September 2022

Racial discrimination and violence against minority communities are prohibited by law, and the protection of these minority groups is protected by the Constitution, national laws, and international laws or conventions ratified by Indonesia, such as ICCPR, and ICERD. Violence cases involving ethnic Papuans are a form of human rights violation that is often ignored by the state. This study will use the normative juridical approach method, by presenting and analyzing the validity of the provisions of the legislation. Socio-legal studies, in this study, will be conducted by conducting an analysis of social studies, the theory of multidisciplinary theory of social sciences, related to the phenomenon of racial discrimination against ethnic Papuans, such as Psychological science in looking at a guess, to discrimination; communication science; Theory of Social Integration and Disintegration; and Social Conflict Theory. The aim of this study was to examine law enforcement, using paradigms in the social sciences. In this study, it will be reviewed on the quality of law enforcement, the extent to which the rules are enforced, as well as the extent to which law enforcement, as well as the government, can fulfill the rights of citizens not to discriminate in it. This research shows that discrimination against the Papuan people is caused by racial discrimination in various aspects, economic, political, educational, law enforcement, etc. The application of anti-discrimination law must be based on the professionalism of law enforcement officers, so as not to cause new discrimination in law enforcement. This study recommends that the Government of Indonesia to further increase political will in the enforcement of anti-discrimination and violence laws in all cases, especially against Papuan ethnic groups. Maximum anti-discrimination law enforcement efforts are needed to realize human rights goals, namely the fulfillment, enforcement, and protection of human rights.

Published: September 2022

Abstract
An appraisal well was drilled in Brazilian pre-salt area using overbalance drilling fluid, with conventional techniques. While drilling reservoir (in a 12 1/4" phase), total losses were found. Unsuccessful attempts with LCM and cement pills revealed that only MPD/PMCD techniques could deliver the well to TD. It was decided to anticipate the installation of the 9 5/8" casing, covering only the upper portion of the reservoir, and well was suspended. The remaining reservoir could be drilled later with a rig equipped with MPD system.
This well was designed as a 2-zones intelligent completion in cased hole configuration. Due to the fluid losses a new design had to be considered. Due to reservoir uncertainties, definition on the separation between zones would only be taken after drilling the remaining reservoir section.
To overcome this challenge without adding time and complexity to the overall design, the best solution was to perforate the cased hole section after drilling the remaining section, meaning doing it with reservoir communicated to the wellbore and in PMCD mode.
Several options were evaluated to design the TCP operation in PMCD. Well control strategies, contingencies, thermal effects, and dynamic shocks were considered. The solution consisted in running the TCP with a closed string, without NRVs and having robust contingencies in case of washout or drillpipe failure after perforating.
The well was drilled, and total fluid losses occurred again. It was then successfully perforated still in PMCD, then lower and upper completion were installed. Despite these challenges, this was the fastest intelligent completion in all Petrobras pre-salt fields so far.

Abstract
In this drilling campaign, out of 6 development wells, MPD/C were utilized in 4 wells. 1 well utilized both MPD for drilling and MPC for 7" casing installation (Well A) and the other 3 wells (Well B, C, D) were drilled conventionally and conducted MPC for 7" casing installation upon confirmed to have a narrow operating drilling window due to the depleted sands which verified by several MPD dynamic leak off tests (DLOT) during drilling resulted satisfied for conducting MPC for 7" 23ppf casing. In both conventional drilling or MPD wells, the job is guided by the drilling window which consist of the pore pressure/collapse pressure serves as the lower limits and fracture pressure serves as the upper bound of the window.
The ability to control the well pressure profile with MPD system led to the Managed Pressure Cementing (MPC) as the alternative method implemented in this narrow pressure margin wells. MPC was planned in detailed by using the advanced MPD hydraulic modeling to model the surge effect of running in hole casing to setting depth and calculate the surface back pressure required to control the annular ECD/ESD during the different stages of cementing operation. Based on the surface back pressure target, the cementing parameters were designed and modelled accordingly to suit the cementing requirements.
This paper presents the engineering design considerations, execution methods and results of four development wells with MPC operations conducted by closing the annular BOP to create the closed loop system to cement 7" 23ppf production casing strings successfully without losses events.
Limbayong Deepwater Development Well Planning – A Collaboration with Geomechanics with MPD Approach

Published: September 2022

Abstract
Limbayong field situated in Sabah, Malaysia is operated by PETRONAS Carigali and is the company's first deepwater operated asset owned and operated by PETRONAS. Limbayong is a flagship project and strategically aims to be the deepwater hub for East Malaysia, particularly Sabah. The first phase of development is to start in Q1 2023. One of the campaign objectives is to produce from the deepest reservoir. However, the recently updated geomechanics model shows that there is a need to drill through with an extremely narrow drilling margin window (less than 0.5 ppg) even at the surface section for some of its wells. Most of these deep wells are required to be drilled in highly deviated and in the direction of the minimum horizontal stress. This poses an increased risk of stuck pipe due to hole instability, differential sticking, and skin damage due to high overbalance pressures, which makes drilling these wells challenging and costly.
A mechanical earth model is initially developed based on Limbayong offset. The model has gone through an evolution with the recent model being updated to better fit observation in sand locally and regionally in recent wells drilled. The new reconstruction model significantly reduces the drilling window gap, thus MPD (MANAGED PRESSURE DRILLING) is required to meet the well objective and minimize drilling risk.
By developing and applying those models, it helps to determine the safe operating downhole pressure limits and to effectively assess the drilling risks associated with the planned wellbore orientation. By accurately determining the required bottomhole pressure to prevent wellbore stability problems, managed pressure drilling technology can be implemented to provide improved drilling hazard mitigation by enabling reduced overbalance pressures, constant bottomhole pressure, and faster reaction time by instantaneously adjusting downhole pressures.
This work underscores the development and usage of the advanced multi-phase model to simulate gas influx transport and its effects on BHP (Bottom Hole Pressure) during MPD operations. DrillBench hydraulics modeling was performed to determine the mud weight requirements to be used with the MPD system. Using the lowest MW (Mud Weight) possible to maximize the drilling window and flexibility was implemented as part of scenario simulation.
This paper presents a case study where a holistic approach, combining geomechanics and drilling technologies were employed to address the drilling challenges specific to unconventional and naturally fractured reservoirs. Ultimately, this approach helped to mitigate stuck pipe issues, while proposing an engineering-based methodology to reduce losses by using MPD, hence providing a roadmap to optimized drilling and mitigation of hazards with associated Non-Productive Time (NPT).

A New Approach for Attribute Reduction from Decision Table based on Intuitionistic Fuzzy Topology
Authors: Dai Tran Thanh , LONG GIANG NGUYEN , Thi Vu Duc , Ngan Tran Thi , Chau Hoang Thi Minh , Son Le Hoang 
Published: September 2022

Abstract

Most of the current attribute reduction methods use the measure to define the reduct, such as positive region of rough set theory (RST), granular information entropy, and granular distance measures. However, the reducts defined based on the measures are still limited in sizes because of the information conservation property of the reduct compared to the original dataset. Dealing with this matter, this paper proposes a new approach using the intuitionistic fuzzy topology (IFT) to develop an attribute reduction method to find the reduct with the optimal size through topology. Specifically, the IFT base and IFT sub-base structures are proposed based on the pre-order relation. Secondly, we propose a new measure to evaluate the significance of the attribute based on the IFT sub-base. Lastly, we propose a new definition of the reduct based on the IFT base and design two new algorithms based on Heuristic approaches. The theoretical and experimental results show that the proposed method is efficient in size and accuracy of the reduct
Fine-scale spatial variation shape fecal microbiome diversity and composition in black- tailed prairie dogs (Cynomys ludovicianus)
Authors: Neha Sufia A. , Salazar-Bravo Jorge 
Published: September 2022

Abstract

Background
Host associated gut microbiota are important in understanding the coevolution of host-microbe, it’s causes and consequences that may help wildlife population to adapt to its rapid climatic changes. Mammalian gut microbiota composition and diversity may be affected by a variety of factors including geographic variation, seasonal variation in diet, habitat disturbance, environmental conditions, age, and sex. However, there have been few studies that have examined how ecological and environmental factors influence gut microbiota composition in animals' natural environments. In this study, we explore how host habitat, geographical location and environmental factors affect the fecal microbiota of Cynomys ludovicianus at a small spatial scale. We collected fecal samples from five geographically distinct locations in Texas Panhandle occupying habitat classified as urban and rural areas using high throughput 16S rRNA gene amplicon sequencing.
Results
The results showed that microbiota of fecal samples was largely dominated by phylum Bacteroidetes. Fecal microbiome diversity and composition differed significantly across sampling sites and habitats. Prairie dogs inhabiting urban areas showed reduced fecal diversity due to more homogenous environment and anthropogenic disturbance. Urban prairie dog colonies displayed greater phylogenetic variation than those in rural habitats. Differentially abundant analysis revealed that bacterial species pathogenic to humans and animals were highly abundant in urban areas which indicates that host health and fitness might be negatively affected. Random forest model identified Alistipes shahii as the important species driving the changes in fecal microbiome composition. Despite the effects of habitat and geographic location of host, we found a strong correlation with environmental factors- average maximum temperature was the best predictor of prairie dog fecal microbial diversity.
Conclusions
Our findings suggest that reduction in alpha diversity in conjunction with greater dispersion in beta diversity could be indicative of declining host health in urban areas which could help determine in future conservation efforts. Moreover, several bacterial species pathogenic to humans and other animals were highly abundant in prairie dog colonies near urban areas, which may in turn adversely affect host phenotype and fitness.

Abstract
Since the COVID-19 pandemic originated in Wuhan, China in early December 2019, millions of lives have been lost. In an epidemic, it is necessary to explore the number of infections and deaths, identify the populations at risk, and determine the factors influencing disease death. The Retrospective cohort study used of 2110 hospitalized patients with COVID-19 data recorded in the Medical Care Monitoring Center information system from March 1, 2020, to February 7, 2021, in the city of Rafsanjan. Among a total of 2110 hospitalized patients (mean age: 56.11, SD: 19.37 years), there were 1125 (54.2%) females, 228 (10.8%) readmissions, and 318 (15.1%) deaths. The highest percentage (70.2%) of hospitalized patients with COVID-19 was infected during the third and early fourth waves. Mortality was high in elderly patients, males, patients with underlying diseases, and those who ‎received mechanical ventilation. The in-hospital mortality trend decreased from the first (19.2%) to the second wave (10.7%) and increased ‎significantly during the third and early fourth waves ‎‎ (16.3%) (P < 0.01).The median 43-day in-hospital survival time was 17 days. An adjusted Multivariable logistic regression showed the age as a strong risk factor for deaths due to COVID-19 while also indicating in both age sub-group analyses that cancer, CKD, neurologic disease, opium, and diabetes were associated with increased odds of death. Finally, patients aged ≥ 65 with CVD and COPD and patients aged < 65 with hypertension were associated with increased odds of death. The area under the ROC curve was 0.809 (95% CI: 0.76–0.83, P < 0.001) to discriminate between discharge and death on hospitalized patients with COVID-19. Our study showed that the effect of the pre-existing chronic diseases on the mortality of COVID-19 varied by age, Also opium was an independent risk factor for in-hospital mortality of COVID-19.

Abstract
Background: The greatest mortality and disability from stroke occurs in low- and middle-income countries. A significant barrier to implementation of best stroke care practices in these settings is limited availability of specialized healthcare training. We conducted a systematic review to determine the most effective methods for the provision of speciality stroke care education for hospital-based healthcare professionals in low-resource settings.
Methods: We followed the PRISMA guidelines for systematic reviews and searched PubMed, Web of Science and Scopus for original clinical research articles that described or evaluated stroke care education for hospital-based healthcare professionals in low-resource settings. Two reviewers screened titles/abstracts and then full text articles. Three reviewers critically appraised the articles selected for inclusion.
Results: A total of 1,182 articles were identified and eight were eligible for inclusion in this review; three were randomized controlled trials, four were non-randomized studies, and one was a descriptive study. Most studies used several approaches to education. A “train-the-trainer” approach to education was found to have the most positive clinical outcomes (lower overall complications, lengths of stay in hospital, and clinical vascular events). When used for quality improvement, the “train-the-trainer” approach increased patient reception of eligible performance measures. When technology was used to provide stroke education there was an increased frequency in diagnosis of stroke and use of antithrombotic treatment, reduced door-to-needle times, and increased support for decision making in medication prescription was reported. Task-sharing workshops for non-neurologists improved knowledge of stroke and patient care. Multidimensional education demonstrated an overall care quality improvement and increased prescriptions for evidence-based therapies although there were no significant differences in secondary prevention efforts, stroke reoccurrence, or mortality rates.
Discussion: The “train the trainer” approach is likely the most effective strategy for specialist stroke education, while technology is also useful if resources are available to support its development and use. If resources are limited, basic knowledge education should be considered at a minimum, and multidimensional training may not be as beneficial. Communities of practice, led by those in similar settings, may be helpful to develop educational initiatives with relevance to local contexts.

Abstract
In this paper, an analysis study of two encryption algorithms applied to texts is carried out in order to evaluate their robustness in terms of security. The first is the classical cryptosystems known as, respectively, Advanced Encryption Standard (AES) and Data Encryption Standard (DES). The second comes from the study of chaotic systems by using the Tent map. Experimental results and their analysis show that chaotic encryption algorithm is more secure and high efficiency compared to classical algorithms. In addition, the chaotic system present a good encryption speed.
