Capital Gain Tax Overhang and Price Pressure
SSRN Electronic Journal, 2004ABSTRACTI study whether the capital gains tax is an impediment to selling by some investors and if so, to what degree associated delayed selling affects stock prices. I find that selling decisions by institutions serving tax‐sensitive clients are sensitive to cumulative capital gains, a pattern not observed for institutions with predominantly tax ...

The Effect of Interdialytic Weight Gain on Predialysis Blood Pressure
Artificial Organs, 1993Abstract: Interdialytic weight gain is believed to influence predialysis blood pressure. Since interdialytic weight gains vary among treatments for individual patients, blood pressure and weight gain data could be examined to determine how weight variations correlate with differences in blood pressure.

Steam injected Humphrey cycle for gas turbines with pressure gain combustion
, 2019Gas turbines are a mature technology and any increase in their efficiency comes at high R&D cost. Pressure Gain Combustion (PGC) has emerged as a concept to significantly improve their efficiency.

Gain anisotropy in low-pressure chemical lasers
Applied Optics, 1983The gain coefficient in a low-pressure chemical laser during lasing differs when viewed along the optical resonator axis and when viewed normal to the axis. Expressions for axial and normal gain coefficients are deduced. The ratio of normal-to-axial gain coefficient is evaluated for a saturated multimode chemical laser employing a Fabry-Perot resonator.

Pressure Gain Combustion by Using Shock Flame Interaction Pressure Rise
Volume 5: Controls, Diagnostics, and Instrumentation; Cycle Innovations; Cycle Innovations: Energy Storage, 2020Abstract Pressure loss across a combustor in a gas turbine reduces thermal efficiency and increases specific fuel consumption. Theoretically, any pressure gain across the combustor results in higher thermal efficiency and lower specific fuel consumption.

Thermal analysis and performance of a pressure gain combustion system
2017Conventional gas turbine engines burn fuel in a steady state combustor at constant pressure, and the pressure rise is obtained by the compressor driven by the turbine. In the Pressure Gain Combustion cycle, the combustion process is at constant volume, allowing an increase of the pressure without the need of the compressor.

Entropy Considerations on Integration of Pressure Gain Combustors
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010The primary goal of this study is to understand the issues associated with integrating the pressure-gain combustion device to a conventional steady state gas turbine engine. The loss of performance due to a poor integration method can be critical. Two types of transitional methods are examined using entropy-based models. An accumulator based transition

An Analytical Approach to Understanding the “Pressure Gain” Combustor
Journal of Energy Resources Technology, 1997Although pulse combustion has been successfully utilized in various commercial applications, one potential application yet to reach the market is the pressure gain gas turbine (PGGT). A PGGT would incorporate a pulse combustor rather than the typical steady-flow combustor to increase system efficiency and decrease pollutant emissions.

A Simple Pressure-Gain Combustor for Gas Turbines
Journal of Engineering for Power, 1977The performance is presented, and a description is given, of a simple pressure-gain combustor, without moving parts, which has been shown, during laboratory trials, to produce a stagnation pressure-gain across the combustor in excess of 5 percent at a combustor stagnation temperature of 3:1.
