An Investigation of Homogeneous and Heterogeneous Sonochemistry for Destruction of Hazardous Waste

EMSP Project Summaries Environmental Management Science Program Project ID Number 54834 An Investigation of Homogeneous and Heterogeneous Sonochemistry for Destruction of Hazardous Waste

An investigation into the frequency of Language Related Episodes in the EFL learners’ Homogeneous and Heterogeneous Dyadic Interaction

This study attempted to compare the relative frequency of the occurrence of Language Related Episodes (LREs) in the dyadic talks of pairs who were homogeneous and heterogeneous in terms of English proficiency.  LREs are those parts of the conversations where the interlocutors explicitly focus on linguistic form. The study was carried out with 60 Iranian university students of teaching English a...

Investigation of Household Hazardous Waste Production in Amirkola, Iran, in 2012-2013

Background and purpose: It is extremely important to recognize the qualitative and quantitative characteristics of this type of waste before any planning on them due to the lack of the prepared program in the field of household hazardous waste (HHW) management in the country. This research has been done in Babol, Iran, in order to achieve this important goal. Materials and Methods: The cross-se...

Efficient Synthesis of Biodiesel From Waste Cooking Oil Catalysed by Al2O3 Impregnated with NaOH

Due to the high price of virgin vegetable oils and the drawbacks of the homogeneous catalytic transesterification, in this work an economically profitable alternative process was proposed for biodiesel synthesis in which transesterification of the low-cost waste cooking oil (WCO) with methanol in a heterogeneous system was done. Alumina impregnated with sodium hydroxide was utilized as a solid ...
