The intensive use of chemical substances such as pesticides, drugs, food additives and industrial chemicals has lead to the subsequent detection of these compounds in many countries. With the improper disposal, they enter the aquatic environment primarily by reaching the wastewater systems. About the residues of pharmaceuticals in the environment, especially in water, is being repeatedly report...

Vapor pressure: 1.33×10 Pa (108.2°C) Partition coefficient: Log Pow = 3.18 (observed value) Degradability: Hydrolyzability: No Report Biodegradability: Poorly biodegradable (BOD=0%, 14 days) Solubility: Water: 137 mg/l (25°C) (observed value) Organic solvents: Soluble in acetone and benzene. Amount of production/import:(1998): 322 t (Production 0 t, Import 322 t) Usage: Raw material for synthes...

The objective of this study was to estimate the protein degradability parameters of 6 common ruminant feedstuff using the nylon bags (in situ) and the innovative in vitro method-the DaisyII incubator. Significant differences were observed between the in situ and in vitro methods in estimation of the rapidly soluble (a) fraction (Pin vitro method were highly correlated with the estimated values ...

The objective of the present study was to evaluate effects of in vitro rumen solubility or degradability of dietary protein on net absorption of nitrogenous compounds from portal-drained viscera of beef heifers. Four protein sources, casein, soya-bean meal, maize-gluten meal and blood meal provided about two-thirds of total dietary nitrogen in semi-purified diets given to four beef heifers in a...

Wang, M., Jiang, J., Tan, Z.L., Tang, S.X., Sun, Z.H. and Han, X.F. 2009. In situ ruminal crude protein and starch degradation of three classes of feedstuffs in goats. J. Appl. Anim. Res., 36: 23-28. Ruminal crude protein (CP) and starch degradability of three classes of feedstuffs: cereals (maize, wheat, barley, buckwheat, rice, millet and sorghum), legumes (horse bean, soybean, pea and mung b...

The objective of this work was to describe a novel in vitro system based on the subtraction of ammonia pools obtained with and without rumen fluid inoculum to determine the soluble protein fraction of feeds and their degradability, with adjustments for microbial contributions and bacterial contamination. Four corn-milling coproducts were used in this study as random factors. The feeds (Fd) were...

In this study, bioactive scaffold of nano magnesium phosphate (nMP)/wheat protein (WP) composite (MWC) was fabricated. The results revealed that the MWC scaffolds had interconnected not only macropores (sized 400-600 μm) but also micropores (sized 10-20 μm) on the walls of macropores. The MWC scaffolds containing 40 w% nMP had an appropriate degradability in phosphate-buffered saline and produc...

The aim of this study was to obtain a composite material which not only has suitable workability but also has excellent degradability. A novel injectable and degradable bone cement consisting of a mixture of calcium phosphate (α-tricalcium phosphate; α-TCP) and calcium sulfate dihydrate (CaSO4. 2H2O; CSD) powders as the solid phase and an aqueous solution containing 2.5 weight percent of Na2HPO...

Prediction of biodegradation processes for the organic fraction of municipal solid waste is an issue of paramount interest for efficient landfill design and management. This paper presents the results obtained from an extended field work developed in a time period of ten years. Solid waste samples from a landfill were collected at different depths in 5 holes with depth of 17 m, and analyzed in ...
