Book Review: Global Indigenous Health: Reconciling the Past, Engaging the Present, Animating the Future
Authors: Battiston Chris 
Published: April 2021

Literature about Indigenous health has dramatically increased over the past few years, which has made it difficult to stay current—this is a good thing. This uptick indicates that this work is getting attention it deserves. However, every so often a collection comes along that provides an essential overview of the work being done, and Global Indigenous Health: Reconciling the Past, Engaging the Present, Animating the Future is one such book. It examines the impacts and effects of health determinants on Indigenous Peoples from across the globe, including Micronesia, Alaska, and Canada.
Políticas educativas y formación de la ciudadanía del futuro en Chile y España (1970-2016)
Authors: García Fernández Gonzalo Andrés 
Published: April 2021

Objetivo: este artículo tiene como propósito, estudiar comparativamente las legislaciones educativas española y chilena (1970-2016) en el marco de la formación ciudadana, con el fin de analizar los proyectos de la sociedad de futuro que se abordan, así como sus principales características.
Originalidad/aporte: este dado de la discusión de los análisis propuestos se considera relevante dadas, en primer lugar, la naturaleza comparada del trabajo y, en segundo lugar, la pertinencia de las interrogantes desarrollas en los conceptos y criterios tradicionalmente utilizados en educación y, específicamente, en materia de formación ciudadana (ciudadanía, participación, política, etc.).
Método: El trabajo fue de naturaleza cualitativa, siguiendo una investigación documental (leyes educacionales) y también teórico-conceptual, con la finalidad de crear nuevos debates con respecto a las problemáticas políticas que giran en torno a la formación ciudadana en perspectiva prospectiva.
Estrategias/recolección de información: las estrategias de recolección de información de la literatura especializada (problema educativo), así como de una revisión de miradas teóricas críticas (problema político) para abordar en los planes específicos de formación ciudadana los esfuerzos concretos acerca de qué tipo de perfil (ideal) de ciudadanía se pretenden construir. Como veremos en este artículo, dicho planes y proyectos estarán delimitados, en gran medida, por criterios supranacionales (contexto de la problemática).
Conclusiones/: Todo parece apuntar hacia un plan por conservar “viejos” conceptos como modernidad y progreso, en vistas de un auténtico revival en forma de “hipermodernidad” sujeta a las nuevas reglas (económicas) del progreso en el marco de la formación ciudadana (educación).
O lakou haitiano e suas práticas
Authors: Bulamah Rodrigo Charafeddine 
Published: April 2021

A partir do conceito de lakou, em contextos rurais haitianos, e de suas características, farei uma reflexão sobre estudos realizados no Haiti em meados do século XX, em busca do que se compreendia como família e casa nesses trabalhos. Tendo em mente o incômodo causado por declarações que pregaram a crise e a morte do lakou, analisarei uma situação de nominação que acompanhei, revelando práticas que permanecem, mesmo quando alterações drásticas acometem a vida das pessoas. Em um segundo momento, deter-me-ei em questões ligadas ao parentesco ritual, às formas de organização do trabalho e dos mercados. Pensar o lakou é, de certa forma, levar em conta a história e os processos de transformação pelos quais o Haiti, em sua diversidade, passou e tem passado.

Analysis of Pressure Interference Tests in Unconventional Gas Reservoirs: A Gas Condensate Example from Montney Formation
Authors: Haghshenas Behjat , Qanbari Farhad 
Published: April 2021

Abstract
Characterization of hydraulic fracture system in multi-fractured horizontal wells (MFHW) is one of the key steps in well spacing optimization of tight and shale reservoirs. Different methods have been proposed in the industry including core-through, micro-seismic, off-set pressure data monitoring during hydraulic fracturing, pressure depletion mapping, rate-transient analysis, pressure-transient analysis, and pressure interference test. Pressure interference test for a production and monitoring well pair includes flowing the production well at a stable rate while keeping the monitoring well shut-in and recording its pressure.
In this study, the coupled flow of gas in hydraulic fractures and matrix systems during pressure interference test is modeled using an analytical method. The model is based on Laplace transform combined with pseudo-pressure and pseudo-time. The model is validated against numerical simulation to make sure the inter-well communication test is reasonably represented. Two key parameters were introduced and calculated with time using the analytical model including pressure drawdown ratio and pressure decline ratio.
The model is applied to two field cases from Montney formation. In this case, two wells in the gas condensate region of Montney were selected for a pressure interference test. The monitoring well was equipped with downhole gauges. As the producing well was opened for production, the bottom-hole pressure of the monitoring well started declining at much lower rate than the production well. The pressure decline rate in the monitoring well eventually approached that of the producing well after days of production. This whole process was modeled using the analytical model of this study by adjusting the conductivity of the communicating fractures between the well pairs.
This study provides a practical analytical tool for quantitative analysis of the interference test in MFHWs. This model can be integrated with other tools for improved characterization of hydraulic fracture systems in tight and shale reservoirs.

Published: April 2021

Summary
Our objective is to present selected rheological and mechanical properties of rock-based geopolymers contaminated with different concentrations of drilling fluids. The possible flash setting and the maximum intake of drilling fluids before seeing a dramatic deterioration of the geopolymers are presented.
Rock-based geopolymers designed for cementing conductor and surface casing were prepared and cured for up to 28 days at 22°C and atmospheric pressure. Water-based drilling fluids (WBDFs) and oil-based drilling fluids (OBDFs) were designed in accordance with the recommendations from the petroleum industry. The fluid samples were prepared, and their viscous behavior was characterized before and after hot-rolling. The geopolymeric slurries were mixed and then blended with the prepared drilling fluid volumes. The contaminated geopolymeric slurries were cured and tested at different time intervals. American Petroleum Institute (API) Class G neat cement was used as a reference. These samples were cured and contaminated with the same drilling fluids. The properties of contaminated geopolymer slurries were benchmarked with those of the contaminated Class G cement.
The obtained mechanical properties showed that the rock-based geopolymers are more sensitive to WBDFs than to OBDFs. However, for contaminated Portland cement samples, the obtained results were opposite, and the contamination effect of OBDF on cement was more noticeable than WBDF. The impact of geopolymer contamination is a function of curing time. Although geopolymeric samples showed dramatic strength retrogression at the early time, strength buildup of the samples compensated for the impact of contamination.
Experimental Study of Microgel Conformance-Control Treatment for a Polymer-Flooding Reservoir Containing Superpermeable Channels

Published: April 2021

SummaryPolymer flooding has been widely used to improve oil recovery. However, its effectiveness would be diminished when channels (e.g., fractures, fracture-like channels, void-space conduits) are present in a reservoir. In this study, we designed a series of particular sandwich-like channel models and tested the effectiveness and applicable conditions of micrometer-sized preformed particle gels (PPGs, or microgels) in improving the polymer-flooding efficiency. We studied the selective penetration and placement of the microgel particles, and their abilities for fluid diversion and oil-recovery improvement. The results suggest that polymer flooding alone would be inefficient to achieve a satisfactory oil recovery as the heterogeneity of the reservoir becomes more serious (e.g., permeability contrast kc/km &gt; 50). The polymer solution would vainly flow through the channels and leave the majority of oil in the matrices behind. Additional conformance-treatment efforts are required. We tried to inject microgels in an attempt to shut off the channels. After the microgel treatment, impressive improvement of the polymer-flooding performance was observed in some of our experiments. The water cut could be reduced significantly by as high as nearly 40%, and the sweep efficiency and overall oil recovery of the polymer flood were improved. The conditions under which the microgel-treatment strategy was effective were further explored. We observed that the microgels form an external impermeable cake at the very beginning of microgel injection and prevent the gel particles from entering the matrices. Instead, the microgel particles could selectively penetrate and shut off the superpermeable channels under proper conditions. Our results suggest that the 260-µm microgel particles tested in this study are effective to attack the excessive-water-production problem and improve the oil recovery when the channel has a high permeability (&gt;50 darcies). The gels are unlikely to be effective for channels that are less than 30 darcies because of the penetration/transport difficulties. After the gels effectively penetrate and shut off the superpermeable channel, the subsequent polymer solution is diverted to the matrices (i.e., the unswept oil zones) to displace the bypassed oil. Overall, this study provides important insights to help achieve successful polymer-flooding applications in reservoirs with superpermeable channels.

Published: April 2021

Abstract
Background: The high incidence and mortality of lung cancer have seriously affected human life and health. Nivolumab is a monoclonal antibody that can inhibit programmed death 1 (PD-1) and Ipilimumab is a monoclonal antibody against CTLA-4(cytotoxic T lymphocyte-associated antigen 4), both of which can prevent the immune escape of tumor cells. Our goal was to synthesize evidence from published randomized controlled trials involving the safety and efficacy of either Nivolumab alone or in combination for the treatment of unresectable lung cancer. Methods: We searched the following electronic databases: PubMed, Embase, and Cochrane libraries, and screened the retrieved records for eligibility. We used the Stata16 software for the analyses. The results of the analysis are expressed as hazard ratios (HRs) or risk ratios (RRs) and their corresponding 95% confidence intervals (CI). Results: The final analysis included nine trials involving 4754 patients. Among patients with advanced lung cancer, patients using immunosuppressive therapy had better overall survival (OS), progression-free survival (PFS), and an objective response rate (ORR) than patients receiving chemotherapy. The HR of Nivolumab monotherapy or combination therapy with OS was compared with that of chemotherapy (HR: 0.73, 95% CI: 0.64–0.83; HR: 0.75, 95% CI: 0.60–0.93), and the HR of PFS was (HR: 0.81, 95% CI: 0.69–0.94; HR: 0.86, 95% CI: 0.76–0.98). Conclusions: Immunotherapy has been shown to have more clinically meaningful survival benefits for patients with lung cancer, whether monotherapy or combination immunotherapy.Systematic review registration PROSPERO CRD42020213440.
