چکیده
Introduction The co-digestion of manure with other substrates such as energy crops, industrial wastes, or food industry wastes enhances biogas production. The addition of co-substrates to manure can improve the carbon to nitrogen balance which results in a stable and maintainable digestion process [1]. Co-digestion also improves the flow qualities of the co-digested substrates [2]. Perhaps the most important drivers for co-digestion of manure with other substrates are the financial benefits associated with the increased biogas yields and income generated from tipping fees when wastes are used as co-substrates. Several studies have been conducted to determine the optimum biogas and methane yields associated with the co-digestion of manure with cosubstrates including: corn silage, switchgrass, canola seed cake, whey, waste grease, food waste and corn stillage.

Diastereoselective Synthesis of Stable Phosphorus Yields by a Three-Component Reaction between Ph3P and Acetylenic Esters in the Presence of Hydrazine Derivatives
In this work, stable crystalline phosphorus yields are obtained in good yields from the 1:1:1 addition reactions between hydrazine derivatives and dialkyl acetylenedicarboxylates in the presence of triphenylphosphine at room temperature in dichloromethane. This synthetic method has merits of high yields, mild reaction conditions, and simple experimental and work-up conditions. The obtained yiel...
متن کاملImpacts of projected changes and variability in climatic data on major food crops yields in Rwanda
This paper investigated the response of major food crop yields namely beans,cassava, Irish potatoes, maize and sweet potatoes to ongoing changes in climate inRwanda. The projected daily precipitation and temperature data for the period2000-2050 used in this study were generated by stochastic weather generator(LARS-WG) from daily raw data for the period 1961 -2000. These data werecollected from ...
متن کاملSimulation of Yield Decline as a Result of Water Stress Using BUDGET Model
In this paper, to account for the effect of water stresses in the various growth stages under deficitirrigation, the multiplicative, seasonal and minimal approaches are integrated in the BUDGETmodel. To evaluate the model, the simulated yields for winter wheat (was grown in Sharif Abaddistrict) under various levels of water stress were compared with observed yields. The resultshowed, simulated ...
متن کاملResources for new research directions in speaker recognition: the mixer 3, 4 and 5 corpora
This paper describes new language resources designed to support research in speaker recognition. It begins with a brief overview of collections protocols, motivates the shift from the Switchboard protocol to the Mixer protocol, summarizes yields from the earliest phase of Mixer collection and then describes more recent phases, yields and expected yields and lessons learned.
