Laboratory and full-scale experiments were conducted for enhancing the coagulation of stabilised surface waters with high organic content by permanganate preoxidation. It was indicated that permanganate preoxidation enhanced both the processes of coagulation and filtration of selected surface waters, River Songhua water, Qitaihe Reservoir water and Ba Reservoir water. Permanganate preoxidation ...

A comprehensive assessment of heavy metals and organic content was performed for leachates produced from a number of old and new landfills in Jordan over 9 month in efforts to set a framework for treatment regulations. All leachates were basic (pH = 7 9) and have high electric conductivity and high organic contents (COD = 3000 500,000 mg/L, TOC= 500 21,000 mg/L). The organic content was inverse...

The objective of this study was to estimate the differences in fattening performance, carcass traits and meat characteristics of Prestice Black-Pied (PBP) pigs and (BuxL)x(HxPn) crossbreed pigs (C) reared under organic free-range system or conventional indoor feeding system. PBP pigs under conventional system were characterized by lower average daily gain and worse carcass traits (lower meat pe...

The definition of soil quality encompasses physical, chemical and biological characteristics, and it is related to fertility and soil health. Many indicators can be used to describe soil quality, but it is important to take into account sensitivity, required time, and related properties, than can be explained. Properties related to organic matter content, such as C/N ratio, organic carbon fract...

The aim of this study was to investigate the preparation of oil-in-water (O/W) nanoemulsions using an emulsification–evaporation process. Nanoemulsions were formed by homogenizing 10 wt% of an organic phase composed by corn oil and hexane mixed at different ratios, and 90 wt% emulsifier solution containing 1.0 wt % of Tween 20 (T20) or β-lactoglobulin (β-Lg). Nanoemulsions were prepared using a...

Long-term application of fertilizers containing P, especially organic fertilizers, usually increases the water soluble and available P of soil and at the same time may result in P accumulation in soil. Organic fertilizers may also increase movement of P in the soil profile that could result in surface and ground water pollution. An experiment was conducted on field plots that received three app...

A big challenge in studying organic rich shale is to predict its kerogen content and maturity from indirect observations. Kerogen maturation changes shale texture; for example, it generates microcracks and fractures in the matrix. Assessment of maturity from indirect measurements can be greatly enhanced by exploiting any existing correlations between physical properties, microstructure, and ker...

Moso bamboo (Phyllostachys edulis) is one of the widely growing bamboo species in Asia. Because of its fast growth and aggressive rhizomes, it is reported to invade other forests and reduce the biodiversity of forest ecosystems. To determine the changes in soil nutrient conditions due to moso bamboo invasion, this research measured the difference in soil labile carbon (C) and nitrogen (N) conte...

this study was conducted to study the effect of organic acids on the preservation of alfalfa nutritional value after harvesting. a split plot design with 4 treatments and 3 times was conducted in which organic acids were sprayed on the 30percent moisture content forage before baling. treatments were: 1) forage without additives as control, 2) pure propionic acid, 1percent, 3) acetic acid percen...

Histosols (also known as organic soils, mucks, or peats) are soils that are dominated by organic matter (OM > 20%) in half or more of the upper 80 cm. Forty two states have a total of 21 million ha of Histosols in the United States. These soils, when intensively cropped, are subject to wind erosion resulting in loss of crop productivity and degradation of soil, air, and water quality. Estimatin...
