Wettability of rock minerals and the underlying surface forces: A review of the implications for oil recovery and geological storage of CO.

The wettability of subsurface minerals is a critical factor influencing the pore-scale displacement of fluids in underground reservoirs. As such, it plays a key role in hydrocarbon production and greenhouse gas geo-sequestration. We present a comprehensive and critical review of the current state of knowledge on the intermolecular forces governing wettability of rock minerals most relevant to subsurface fluid storage and recovery.

Laparoscopic management of large colonic lipoma with atypical presentation: A case report.

Unlabelled: Colonic lipomas (CL) are a rare condition that typically causes symptoms in only a minority of patients. When large lipomas occur, they often necessitate extensive surgery, which carries significant risks.

Case Presentation: We present a case of a female patient who experienced abdominal pain and urinary urgency due to a large, 80 % obstructive lipoma in the descending colon.

Beliefs and practices of physicians in Lebanon regarding promotional gifts and interactions with pharmaceutical companies.

Background: Pharmaceutical companies invest greatly in promotional gifts to influence prescription of medications by physicians, yet there is limited published information evaluating its impact on healthcare.

Aim: This study aimed to assess the beliefs and practices of physicians in Lebanon regarding promotional gifts and their interactions with representatives of pharmaceutical companies.

Methods: This cross-sectional study was conducted between December 2019 and January 2020 through an email-based questionnaire sent to 5936 physicians of different specialties registered in the Lebanese Order of Physicians.

Pore-Scale Study of Wettability Alteration and Fluid Flow in Propped Fractures of Ultra-Tight Carbonates.

The in situ change in oil flow behavior inside propped fractures due to wettability alteration of proppant grains and fracture surfaces was thoroughly investigated for the first time in this study. A series of microscale flow experiments were performed in mixed-wet fractured and propped miniature ultra-tight carbonate cores where the effect of wettability on oil bridging and fracture oil layer integrity was probed during oil production. During the initial production, proppant wettability changed toward an intermediate-wet state (contact angle (CA) = 96°) while that of fracture surfaces became strongly oil-wet (CA = 139°).

Auto-segmentation technique for SEM images using machine learning: Asphaltene deposition case study.

Enormous efforts have been attempted to replace the subjective human analysis of digital images by automated computational methods such as image processing and computer vision. The image processing methods (i.e.

Biomechanical comparison of strategies to adjust axial stiffness of a hybrid fixator.

Objectives: To evaluate strategies for increasing the axial stiffness of a hybrid external bone fixator.

Materials And Methods: Type Ia hybrid fixators, consisting of a uniplanar linear component connected to a circular ring, were tested in displacement controlled loading in axial compression. The basic hybrid construct was modified to explore strategies considered to increase fixator stiffness including: decreasing ring diameter, increasing ring thickness, adding pins to the ring fixation, and adding struts between the ring and vertical post components of the device.

Breast cancer in Egypt: a review of disease presentation and detection strategies.

Carcinoma of the breast is the most prevalent cancer among Egyptian women and constitutes 29% of National Cancer Institute cases. Median age at diagnosis is one decade younger than in countries of Europe and North America and most patients are premenopausal. Tumours are relatively advanced at presentation.

Effects of analgesics during labor.

Four analgesic agents were studied during labour: pethidinesparine, ketamine hydrochloride, nitrous oxide-oxygen, and trichloroethylene in air (Trilene). Excellent analgesia was achieved with ketamine, however hallucinations were troublesome. Trichloroethylene analgesia was good without side-effects.

Serum lysozyme, serum proteins, and immunoglobulin determinations in nonspecific inflammatory bowel disease.

The serum levels of lysozyme, serum electrophoresis, and serum immunoglobulins were determined prospectively in 101 patients with ulcerative colitis, ulcerative proctitis, Crohn's disease, or nonclassifiable nonspecific inflammatory bowel disease. Although the mean serum lysozyme concentration of patients with Crohn's disease (10.5 +/- 6.
