We investigate the existence of customer-based discrimination in Major League Baseball using a direct measure of customer preference, allstar balloting. Unlike other measures used in the literature, such as trading-card prices, our data do not su er from hard to measure monetary in uences on preference. Using allstar votes from 1992 through 1996, and controlling for various player and team-spec...

Recent interest in cube satellites over the last few years has created related interest in propulsion for small satellites. Cubesats, more than other satellites, are volume and power constrained, which pose significant challenges for implementation of cubesat propulsion systems. R-134a propellant systems can provide low cost and efficient propulsion for small impulse maneuvers, orbital maintena...

Compost as a soil supplement significantly enhanced levels of ascorbic acid (AsA) and glutathione (GSH) and ratios of AsA/dehydroascorbic acid (DHAsA) and GSH/oxidized glutathione (GSSG) in fruit of two strawberry (Fragaria x ananassa Duch.) cultivars, Allstar and Honeoye. The peroxyl radical (ROO(*)) as well as the superoxide radical (O(2)(*)(-)), hydrogen peroxide (H(2)O(2)), hydroxyl radical...

in order to investigate the water deficit impact on physical characteristics of seed in four sunflower hybrids (azargol, allstar, hysun 33 and hysun25), under three irrigation regimes (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan, respectively) and experiment was conducted. sampling was done at the end of growing period (season) when the moisture conte...

Our lives have changed dramatically since the spring of 2020 due to new coronavirus infection COVID-19. And in an environment where we are required coexist with virus for foreseeable future, teleworking work remotely and social distancing maintain intervals between people required. Thorough prevention measures" "ensuring availability healthcare delivery systems" remain critical. Recent studies ...

We present the results of near-infrared observations of extragalactic Cepheids made with the Near Infrared Camera and Multi-Object Spectrometer on board the Hubble Space Telescope. The variables are located in the galaxies IC 1613, IC 4182, M31, M81, M101, NGC925, NGC1365, NGC2090, NGC3198, NGC3621, NGC4496A and NGC4536. All fields were observed in the F160W bandpass; additional images were obt...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...
