Simulation and sensitivity analysis of a natural gas liquefaction cycle

Revista Técnica de la Facultad de Ingeniería, 2016
A sensitivity analysis of a Natural Gas (NG) Liquefaction Cycle with mixed refrigerant was done varying the operational conditions. It was used PROII/8.1® to simulate the process and in each case study the variation of the coefficient of performance (COP)

Shear behaviors of recycled aggregate sand in constant volume simple shear tests interrelated with particle shape

Frontiers in Earth Science, 2023
Compared with quartz sand, recycled aggregate sand is characterized by the high liquefaction and shear resistance because of its irregular particle shape.

Unified analysis of liquefaction and the ground flow phenomenon [PDF]

International Applied Mechanics, 2007
Loose saturated sand behaves as a solid before liquefaction but as a fluid when the excess pore water pressure equals the initial confining stress, after which it recovers its strength. A simple constitutive equation for loose saturated sand was developed to express the phase transformation between a solid and fluid during liquefaction and the ground ...

Overview geotechnical model tests on dike safety at Deltares [PDF]

, 2012
Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed.

Bioprinting of Microtissues Within Mechanically Tunable Support Baths to Engineer Anisotropic Musculoskeletal Tissues

Advanced Science, EarlyView.
This study presents a novel 4D bioprinting platform for engineering biomimetic musculoskeletal grafts. By tuning the mechanical properties of support baths, we enhance tissue fusion, collagen alignment, and cell differentiation. Using this strategy, we successfully fabricate scaled‐up, anisotropic tissues such as meniscus, articular cartilage, and ...

NIR‐Activatable Domino Cascade Catalysis Nanozyme Reactor for Multi‐Mechanism Synergistic Immunotherapy in Bladder Cancer

Advanced Science, EarlyView.
This study presents an intravesical delivery strategy of ferroptosis‐ and immunity‐inducing nanozyme‐loaded thermoresponsive hydrogels (FMCC@PNH) for enhanced bladder cancer therapy. Abstract Current intravesical therapies for bladder cancer after resection are limited by poor tissue penetration, off‐target effects, and insufficient efficacy.

Note: "Lock-in accelerometry" to follow sink dynamics in shaken granular matter [PDF]

, 2014
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental Physics, but also for geophysical processes and construction on sediments or granular soils in areas potentially affected by earthquakes.
