—We investigated the relationships of vegetation communities to environmental variables and compared the relative contribution of native and introduced species in extant forest communities on St. John, US Virgin Islands, using an island-wide forest vegetation inventory and monitoring network of permanent plots. We detected 2,415 individuals of 203 species, 5 percent of which were introduced. Cl...

Waste molding and core sands from the foundry industry are successfully being used around the world in geotechnical and soil-related applications. Although waste foundry sands (WFSs) are generally not hazardous in nature, relevant data is currently not available in Argentina. This study aimed to quantify metals in waste molding and core sands from foundries using a variety of metal-binder combi...

Harvests of crops, their trade and consumption, soil erosion, fertilization and recycling of organic waste generate fluxes of phosphorus in and out of the soil that continuously change the worldwide spatial distribution of total phosphorus in arable soils. Furthermore, due to variability in the properties of the virgin soils and the different histories of agricultural practices, on a planetary ...

this study investigated the fatty acids profile, oxidative stability indices, and bioactive compounds of virgin and processed olive oils (leccino and frantoio cultivars). results showed that fatty acid profile of the studied oils contained mostly oleic acid followed by palmitic and linoleic acid. acid values of virgin frantoio and processed leccino were 0.78 and 0.18 mg koh/g oil, with peroxide...

BACKGROUND Coconut oil is commonly used as herbal medicine worldwide. There is limited information regarding its effects on the developing embryo and infant growth. METHODS We investigated the effect of virgin coconut oil post-natally and until 6 weeks old in mice (age of maturity). Females were fed with either standard, virgin olive oil or virgin coconut oil diets 1 month prior to copulation...

Rare earth elements (REE) are essential for sustainable energies such as solar and wind power, with rising demand due to the ambitious goal a circular society. REE currently mined from virgin ores while REE-rich contaminated soil is left untreated in environment. Soil remediation strategies needed that concomitantly cleanup harvest metals contribute process economy. In this review we aim (i) de...

The aim of the article is to study direction negative changes in water-physical properties occurring meadow-chernozem soils under influence anthropogenic factor. "soil keys" method was used determine location transects. Field researches were conducted on same-type relief areas, when comparing virgin and arable variants soils. Soil samples taken from main sections by genetic horizons. In results...

in the present study, the oxidative stability of nine iranian commercial olive oils, including four virgin samples and five deodorized ones, was compared to that of two foreign virgin olive oils. in total, the foreign samples had the mufa/pufa ratios (av. 9.27) higher than those of domestic ones (av. 5.70). the peroxide and acid values of the olive oils studied ranged from 8.5 to 14.5 meq/kg an...
