Vibration analysis of large bulb tubular pump house under pressure pulsations
Water Science and Engineering, 2009 A 3D finite element model of the Huaiyin third pumping station of the Eastern Route of the South-to-North Water Transfer is described in this paper. Two methods were used in the calculation and vibration analysis of the pumping station in both the time ...

Intense Mass Loss from C-rich AGB Stars at low Metallicity?
, 2008 We argue that the energy injection of pulsations may be of greater importance to the mass-loss rate of AGB stars than metallicity, and that the mass-loss trend with metallicity is not as simple as sometimes assumed.

Mud pump pressure pulsation control systems
, 2023 Drilling fluid is circulated through the well-bore during drilling operations to transport cuttings from the bottom of the hole to the surface. Hydrostatic high-pressure mud pumps are typically used for this purpose. Triplex pumps, which comprise three pistons mechanically displaced by 120 degrees, are the most common type of mud pump.

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Pulsational frequency and amplitude modulation in the δ Sct star KIC 7106205 [PDF]
, 2014 Analysis of the Kepler δ Sct star KIC 7106205 showed amplitude modulation in a single pressure mode, whilst all other pressure and gravity modes remained stable in amplitude and phase over the 1470 d length of the data set.

FEBS Open Bio, EarlyView.This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Non-radial Pulsations in the Open Cluster NGC 3766 [PDF]
, 2009 Non-radial pulsations (NRPs) are a proposed mechanism for the formation of decretion disks around Be stars and are important tools to study the internal structure of stars.

Passive pressure pulsation damping using shaped nozzles [PDF]
Scientific Letters of Rzeszow University of Technology - Mechanics, 2014 Pressure pulsations in intake and outlet systems of positive-displacement compressors are one of the most important problems in compressed gas pipelines. This problem occurs not only in huge compressed systems, such as the natural gas piping in gas mines or national gas transport systems, but also in small refrigeration compressors in domestic ...
