Stability analysis of a bilayer contained within a cylindrical tube
… the passage of air. This is known as airway closure. A stability analysis is carried out for the case when a Newtonian and immiscible liquid bilayer coats a compliant tube in the presence of an insoluble surfactant monolayer at the mucus-gas interface. A surface active material such as …

Platelet Function in Dogs with Chronic Liver Disease
… chronic liver disease have prolonged platelet closure time (CT), assessed with the PFA-100®, and buccal mucosal bleeding time (BMBT), and increased vWF concentration compared to healthy dogs. Animals: Eighteen dogs with chronic acquired liver disease undergoing ultrasound-guided needle biopsy …

Autonomous triggering system and measurement protocols for smart bridge testing
… from a load test while minimizing setup time at the bridge and closure time to traffic. Secondary objectives are minimizing the number of personnel required for the test and removing the need for personnel with specialized knowledge at the test site. The smart instrumentation consists of …

A Feasiblity Study on the Fatigue Performance of Laser Beam Welds and Hybrid-Laser Arc Welds Used in an Innovative Modular Steel Sandwich Panel Bridge Deck SyStem
… load reduction, rapid construction, decreased closure time, and automated mass production. The lack of fatigue data for the laser "stake" welds used to create the enclosed sandwich panel geometry raised concerns with respect to fatigue life. The primary focus of this study was to determine …

Experimental and Numerical Investigation of Nanotechnology on Foam Stability for Hydraulic Fracturing Application
… show that foam stability increases two to three times in the presence of 0.8 wt% silica nanoparticles under 90 ℃. The enhancement of foam lifetime by nanoparticle application allows better proppant suspension, which maintains post-fracture conductivity and minimise productivity loss. The …

An adaptive image processing algorithm for field plant population analysis based on UAV imaging system
… crop science, plant population determines canopy closure time, plant spacing, and weeds competition. For farmers, if plant population can be obtained in time, it can help in crop management decisions on replanting, fertilizer application, and estimation of yield. For agricultural manufacturing …

Computations of fully nonlinear three-dimensional wave-body interactions
… for the dependence of cavity shape and closure time/height on Froude number and body geometry. For floating structures in waves, our focus is on the understanding of the fundamental mechanism and basic characteristics for coupled unstable heave-pitch motions of floating …

Effect of phytoestrogens on breast and prostate cancer cell lines – potential implications for bone metastasis
… results showed no significant reduction in the closure time of the scratch in both cell lines and there was an acceleration in the healing time of the scratch in both cell lines but was significant only in breast cell line (MCF7) with coumestrol after 6 ,12 and 24 hours at concentrations between …

Towards the formation of a forward-boosted beam of neutral antihydrogen for gravitational studies
… beam of antihydrogen atoms, well defined in time, and let it pass through the grids of a moir ́e deflectometer [13] while accelerating because of the influence of the Earth’s gravitational field. By the pattern created by the particles passing through the grids, the displacement due to …
