The dynamics of maturation index, water and oil concentrations, total phenols in olive fruit, together with fatty acids content oil, was studied as a function time after flowering for super-high-density ‘Arbequina’, ‘Arbosana’ ‘Koroneiki’ using data collected three seasons. Oil concentration increased linearly from the middle August until reaching plateau by end November all cultivars, (45.7 g/...

harvest index is one of the important parameters in estimation of modules of seed yield prediction. since, this parameter undergoes changes under various conditions. therefore, this research was aimed to prepare relations to estimate it. for this purpuse, a compound analysis experiment with randomized complete block design with four replications was conducted at the gorgan university of agricul...

Multiple dates of Landsat Thematic Mapper (TM) imagery were analyzed to compare a decade of forest harvest activity in northern Maine’s industrial forest. Unsupervised clustering on three-date sequences of Normalized Difference Vegetation Index classified the harvest type and time period when change occurred. Problematic clusters were reclassified using the Normalized Difference Moisture Index,...

The Powder River Basin in Wyoming and Montana contains the United States' largest coal reserve. The area produces large amounts of natural gas through extraction from water-saturated coalbeds. Determining the impacts of coalbed natural gas-produced efflux water on crops is important when considering its potential use as supplemental irrigation water. We hypothesized that coalbed natural gas wat...

Pycnocycla spinosa aerial parts were collected weekly during four-month growth. Hydrodistillation and gas chromatography coupled with mass spectroscopy techniques were used for essential oil and sesquiterpenes investigation. Thirty-four components were identified, of which the characteristic sesquiterpenes were a -copaene, caryophyllene, a -humulene, b-ionene, d-cadinene, a -calacorene, caryoph...
