Weathered
<p>Weathered focuses on themes of change, accumulation, time, and acceptance. Each artwork holds layers of information and experiences that form a unique narrative for all its viewers. The construction of each piece is a symbol of the physical ability it takes to create each painting. After my …

A study of the colloid obtained from weathered lignite
… by the miners as inferior coal, due to the weathered condition. But when this weathered lignite is treated with sodium hydroxide, and the resulting solution allowed to evaporate to dryness, there is left a hard, shiny substance very similar in appearance to hard coal. This dried product has …

Characterization of TPH biodegradation patterns in weathered contaminated soil
Two weathered, petroleum contaminated soils were studied to determine if weathered products are amenable to bioremediation and to determine which TPH (total petroleum hydrocarbon) fractions were degrading during particular time frames under different remediation alternatives. Delineation of …

Laboratory characterization of a highly weathered old alluvium in San Juan, Puerto Rico
The old alluvium underlying much of metropolitan San Juan was formed in early Pleistocene and has undergone substantial post-depositional weathering in the tropical climate of Puerto Rico, resulting in a special combination of soil mineralogy and structure, with very unusual engineering properties. …

Phytoremediation of Weathered Petroleum in Groundwater by Arroyo Willows in Nutrient Amended On-Site Mesocosms
PHYTOREMEDIATION OF WEATHERED PETROLEUM IN GROUNDWATER BY ARROYO WILLOWS IN NUTRIENT AMENDED ON-SITE MESOCOSMS SARAH BRAGG-FLAVAN A large-scale mesocosm study was conducted to determine if vegetation with willow trees enhances biodegradation and to evaluate the mechanisms of natural biodegradation …

A study of the pH-dependent charge of a selection of highly weathered humic soils
Acid soils have long been associated with increased mobility of metals and the subsequent nutrient toxicity to plants, the cause of which is believed partly to be a reduction in cation exchange capacity (CEC). At the same time the reduction in CEC would result in a decline in the soil's ability to …

The genesis and morphology of three southwest Virginia soils which were developed from material weathered from limestone
… Virginia soils which were formed from material weathered from limestone, were studied by means of mechanical and chemical analyses, and field studies or the soil profiles. The soils used in this investigation are all related in a general way, that is, they all occur within the Gray-Brown …

The chemical response of deep, leached and weathered soils of the Mpumalanga Highveld, South Africa, to irrigation with saline mine water
Coal mining in the Highveld region of Mpumalanga Province, South Africa generates between 14 and 30 million litres of waste water per day. Much of the water is saline (TDS> 2500 mg/I) and has high concentrations of dissolved SO₄²⁻, Ca²⁺ and Mg²⁺. Crop irrigation has been proposed as a useful way to …
