Description of steam chamber shape in heavy oil recovery using 4D microgravity measurement technology

Petroleum Exploration and Development, 2013
4D microgravity measurement is used to study the underground medium, especially underground fluid variation state and process, using repeated measurements of gravity data at different periods. A model of microgravity variation calculation for the Guantao

Active Intra-Abdominal Drainage Following Abdominal Digestive System Surgery: A Meta-Analysis and Systematic Review

Journal of Investigative Surgery, 2023
Background Our objective is to compare the early outcomes associated with passive (gravity) drainage (PG) and active drainage (AD) after surgery. Methods Studies published until April 28, 2022 were retrieved from the PubMed, Cochrane Central Register of ...

Shifting Child Protection Assessments From a Deficit Focus to Assessments Informed by Strengths and Protective Factors: Translating Research Knowledge to Practice

Australian Journal of Social Issues, EarlyView.
ABSTRACT Child protection systems play a critical role in preventing and responding to child maltreatment, yet practices are often predominantly deficit focused. This paper presents a rapid literature review on the strengths, protective factors, and cultural considerations to inform child protection assessment.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Organic bases as additives for steam-assisted gravity drainage

Petroleum Science, 2019
Steam-assisted gravity drainage (SAGD) is a mature technology for bitumen recovery from oil sands. However, it is an energy-intensive process that requires large amounts of steam to heat and mobilize bitumen.

Innervation of the tubarial glands: A hypothesis‐driven anatomical review

The Anatomical Record, EarlyView.
Abstract The tubarial glands have been described as a macroscopic bilateral glandular complex in the posterolateral nasopharynx near the torus tubarius and the pharyngeal opening of the Eustachian tube. Since their recognition on prostate‐specific membrane antigen‐based imaging, their anatomical classification has remained debated, with converging ...

Assessing lymphatic route of CSF outflow and peripheral lymphatic contractile activity during head‐down tilt using near‐infrared fluorescence imaging

Physiological Reports, 2020
Evidence overwhelmingly suggests that the lymphatics play a critical role in the clearance of cerebrospinal fluid (CSF) from the cranial space. Impairment of CSF outflow into the lymphatics is associated with a number of pathological conditions including

Drawdown behavior of gravity drainage wells [PDF]

, 1993
An analytical solution for drawdown in gravity drainage wells is developed. The free-surface flow is viewed as incompressible, and anisotropy effects are included. The well is a line source well, and the reservoir is infinitely large. The model is valid for small drawdowns.

Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according
