The aim of this paper was to study of the effect of fenugreek seed (Trigonella foenum-graecum) and asparagus root (Asparagus officinalis) on in vitro digestibility and kinetics of gas production of alfalfa hay. Fenugreek seed (FS) and asparagus root (AR) were added at different levels (0, 5, 10, 15 and 20% of DM). Total phenolic components of alfalfa hay (AH), fenugreek seed (FS) and asparagus ...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

Dissolved organic matter (DOM) is the most important natural (NOM) fraction which reacts with chlorine to form harmful trihalomethanes (THMs) in water bodies. The characteristics of DOM could be affected by land use catchment, hence comprehensive study understand body important. This was conducted two watersheds different upper stream determine: (1) characteristics, total (TOM), and quality qua...

several factors effect on sorption of polycyclic aromatic hydrocarbons (pahs) in soil. co-existence of metals and organic matter of soil are among important affecting factors on sorptive behavior of pahs. this research investigated the effect of organic matter content and heavy metals (lead, nickel and zinc), on sorption of phenanthrene onto kaolinite. for this purpose, sorption of the organic ...

To evaluate the relationship between total organic carbon (TOC) and Rock-Eval S2 (petroleum potential) of petroleum source rocks, atotal of 180 outcrop samples from the black organic matter–rich facies of Mesozoic strata from a locality of southwest of Iran wereinvestigated using Rock-Eval VI pyrolysis and Leco Carbon Analyzer. The linear regression is applied to determine the correlationbetwee...
