Solar Oscillations and Convection: II. Excitation of Radial Oscillations
, 2000 Solar p-mode oscillations are excited by the work of stochastic, non-adiabatic, pressure fluctuations on the compressive modes. We evaluate the expression for the radial mode excitation rate derived by Nordlund and Stein (Paper I) using numerical ...

Mechanism Analysis on the Fluctuation of Linear Compressor in Refrigerator
Zhileng xuebao, 2019 The experimental results of a refrigerator system with linear compressor showed that there was a period of piston stroke fluctuation as the supply power remained unchanged after an initial start-up adjustment.

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

On Static Pressure Fluctuation between Sirocco Fan Blades in a Car Air-Conditioning System
Journal of Fluid Science and Technology, 2008 In this study, special attention is directed to static pressure fluctuation in a sirocco fan for a car air-conditioning system, because it is expected that there is a close connection between the fluid noise and the pressure fluctuation.

Strong-Coupling Calculation of Fluctuation Pressure of a Membrane Between Walls
, 1999 We calculate analytically the proportionality constant in the pressure law of a membrane between parallel walls from the strong-coupling limit of variational perturbation theory up to third order.
