Nitrogen (N) is usually low in the majority of agricultural and non agricultural soils in Iran, mainly due to the lack of adequate soil organic matter (OM). On the other hand, boron (B) toxicity is becoming more widespread in arid and semi arid regions of this country, where soils or irrigation waters contain relatively high B content. Results of the research indicate that addition of certain p...
Hydroponic systems have become increasingly popular for growers in recent years year-round local production. Whereas optimal air temperature plant growth has been considered, root zone temperatures not examined as thoroughly. The objective of this research was to determine the water growing different types basil hydroponically. Research conducted at greenhouses Stillwater, OK. Seventeen cultiva...
In order to investigate the effects of phosphorous and potassium fertilizers on some important morphological traits, agronomic characteristics and yield of red bean cultivars, an experiment was conducted at Agricultural Research Farm of Islamic Azad University, Arak, in the summer of 2013-2014 and in two consecutive years. This experiment was conducted as split plot based on randomized complete...

A number of different cues allow listeners to perceive musical meter. Three experiments examined effects of melodic and temporal accents on perceived meter in excerpts from folksongs, scored in 6/8 or 3/4 meter. Participants matched excerpts with one of two metrical drum accompaniments. Melodic accents included contour change, melodic leaps, extreme register, melodic repetition, and harmonic rh...
Introduction The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) was launched in September 1997 to provide quantitative data on global ocean bio-optical properties to the Earth science community. Using ratios of the water leaving radiance SeaWiFS imagery can be used to quantify properties such as the chlorophyll concentration (O’Reilly et al., 1998). Algorithms have been developed to use the su...
