(2017)John C. Carapanayiotis was specialized in physical medicine and rehabilitation in the USA in 1948, at a time when the medical world in post-war Greece was ignorant of this specific medical specialty, and the political, ... -
Johnsongrass (Sorghum halepense (L.) pers.) interference, control and recovery under different management practices and its effects on the grain yield and quality of maize crop
(2020)Maize is an important crop grown on significant acreage around the world, and a major constraint for its growth is weed interference. Thus, field studies were conducted to examine johnsongrass interference, control, and ... -
Join the union and be safe: The effects of unionization on occupational safety and health in the european union
(2015)This paper investigates the effect of unionization on occupational safety and health, as measured by the fatal and non-fatal work accidents, after controlling for the country's gross domestic product. It uses a panel sample ... -
Join-queries between two spatial datasets indexed by a single R*-tree
(2011)A spatial join, a common query in Spatial Databases and Geographical Information Systems (GIS), consists in testing every possible pair of data elements belonging to two spatial datasets against a spatial predicate. This ... -
Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ... -
Joint beamforming and power control for CDMA uplink throughput maximization
(2007)We consider joint beamforming and power control as a means to maximize throughput in a CDMA wireless uplink, where a base station equipped with multiple antennas receives from single - antenna wireless users. Throughput ... -
