in this study, a single layer sliced potato was dried using an infrared lamp heating under vacuum over three levels of radiant power including 100, 150 and 200 w, three slices thickness 1, 2 and 3 mm and the absolute pressure of 20, 80, 140 and 760 mmhg. samples were dried in triplicate to achieve 6% moisture content (wet based) which is suitable for long-term storage. drying rate was monitored...

High quality (Q) factor whispering gallery modes (WGMs) can induce nonlinear effects in liquid droplets through mechanisms such as radiation pressure, Kerr nonlinearity, and thermal effects. However, such nonlinear effects, especially those due to radiation pressure, have yet to be thoroughly investigated and compared in the literature. In this study, we present an analytical approach that can ...

Even when we consider Newtonian stars, i.e., stars with surface gravitational redshift, z ≪ 1, it is well known that, theoretically, it is possible to have stars, supported against self-gravity, almost entirely by radiation pressure. However, such Newtonian stars must necessarily be supermassive(Weinberg 1972).We point out that this requirement for excessive large M , in Newtonian case, is a co...

We apply the discrete dipole approximation (DDA) to estimate the radiation pressure cross section for fluffy aggregates by computing the asymmetry parameter and the cross sections for extinction and scattering. The ballistic particle—cluster aggregate and the ballistic cluster—cluster aggregate consisting of either dielectric or absorbing material are considered to represent naturally existing ...

High quality (Q) factor whispering gallery modes (WGMs) can induce nonlinear effects in liquid droplets through mechanisms such as radiation pressure, light scattering, thermocapillarity, Kerr nonlinearity, and thermal effect. However, such nonlinear effects have yet to be thoroughly investigated and compared in the literature. In this study, we first investigate a micron-sized liquid spherical...

Purpose: To investigate tumor interstitial fluid pressure as a prognostic factor for recurrence-free survival in patients with cervical cancer following radiation therapy. Experimental Design: Tumor interstitial fluid pressure was measured in 55 cervical cancer patients who received radiation therapy between August 1998 and September 2002. Interstitial fluid pressure measurements were made befo...

Recent work has shown that the stress tensor components, such as energy density or pressure, of a quantum field can be subject to large vacuum fluctuations. The pressure must averaged in time before fluctuations finite, and probability fluctuation depends upon details averaging much larger than predicted by Gaussian distribution. This paper explores radiation on Rydberg atoms their possible obs...

This Letter reports the experimental realization of a novel, to best our knowledge, active power stabilization scheme in which laser fluctuations are sensed via radiation pressure driven motion they induce on movable mirror. The mirror position and its were determined by means weak auxiliary beam Michelson interferometer, formed in-loop sensor feedback control system. sensing technique exploits...
