Effects of Pore Fluid Properties on Dynamic Slip in Sandstone‐Derived Fault Gouges From the Groningen Gas Reservoir

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

Numerical Analysis Of The Dynamic Behaviour Of Piston Journal Bearing In Axial Piston Pumps And Motors

open access: yes, 2010
This work presents a numerical analysis of the piston dynamic behaviour in axial piston swash plate type pumps and motors. The numerical method adopted is based on the solution of the piston motion equations which depend on the pressure distribution ...

From extracellular entry to intracellular release: A water‐assisted transport cycle for creatine in SLC6A8

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract The creatine transporter (CRT/SLC6A8) plays a key role in cellular energy homeostasis, yet the molecular mechanism underlying creatine transport remains poorly understood. Here, we reconstruct the complete transport cycle of human CRT using a hybrid simulation strategy that combines constant‐force steered molecular dynamics (cf‐sMD) with ...

Research on Control Methods for the Pressure Continuous Regulation Electrohydraulic Proportional Axial Piston Pump of an Aircraft Hydraulic System

open access: yesApplied Sciences, 2019
The objective of this paper is to design a pump that can match its delivery pressure to the aircraft load. Axial piston pumps used in airborne hydraulic systems are required to work in a constant pressure mode setting based on the highest pressure ...

Interrelations of aortic spring function, cardiovascular disease risk factors, and left ventricular diastolic function: The Framingham Heart Study

open access: yesPhysiological Reports, Volume 14, Issue 13, July 2026.
Abstract Mechanical twisting and untwisting of the left ventricle as well as abnormal hemodynamic aortic‐ventricular coupling are recognized as contributors to left ventricular diastolic function. However, energy associated with proximal aortic stretch during systole can be recovered as diastolic elastic recoil that may facilitate diastolic left ...

GRAPHICAL MODELLING AND STUDIES ON HYDRAULIC PUMP PARAMETERS

open access: yesJournal of Industrial Design and Engineering Graphics, 2021
Hydraulic drive can be defined as a set of technical functions through which the transmission of mechanical energy is carried out, from a driver element to a driven one, using a hydraulic environment.

Piston and plunger pumps

open access: yes, 2019
Stapne i klipne pumpe su pumpe koje koriste stap ili klip za usisavanje i tlačenje tekućine. Jedan radni ciklus se sastoji od usisnog i kompresijskog takta. Spadaju u volumetrične pumpe s linearno pokretnim uređajem. Sastavljene su od stapa i stapajice

Measurement of Slipper Behavior in Swashplate-Type Axial Piston Pumps

open access: yesTribology Online
In swash plate type axial piston pumps, slipper/swash plate sliding surfaces is subject to high fluctuating load. Therefore, the slippers are required to provide stable operation and reduce losses due to sliding. The behavior of the slipper fluctuates in
