Assessment of Environmental Changes in the Iraqi Marshes by Index of Biological Integrity
IBI Nature Iraq Marshes Aquatic Ecology
2013/3/11
Preventing water flow through the marshes in southern Iraq was a policy of the previous regime in Iraq during 1990’s. This phenomena lead to tremendous structural changes in ecosystems, however after ...
Phytoplankton Index of Biological Integrity (P-IBI) in Several Marshes, Southern IRAQ
IBI Nature Iraq Marshes Aquatic Ecology
2013/3/12
Indices of Biological Integrity (IBIs) are being increasingly used as useful and direct tools for assessing general health of aquatic ecosystems. Although such ecosystems in Iraq, especially the south...

The objective of this study was to evaluate the efficiency of Moroccan Bt strains against neonate larvae, third instar larvae and emerged adults of Ceratitis capitata. This Mediterranean fruit fly cau...
New Design & Build Biological System through the Use of Microalgae Addressed to Sustainable Development
Environmental Management Microalgae Algal Bloom Lake Restoration Biofuel Feed Additive Waste-water
2013/3/13
Current trends in energy consumption and biofuel manufacturing are neither secure nor sustainable, because they are not provided by necessary cost effective technologies. Further reductions of cost an...
Biological Treatment of Pickling Industry Wastewater in an Activated Sludge Unit
Pickling industry wastewater biological treatment halophilic bacteria
2009/10/14
Biological treatment of pickling industry wastewaters usually result in low COD removal eciencies because of plasmolysis of cells due to high salt content (%3-5) of the wastewater. Utilization of sal...
Comparison Between Biological Treatment and Chemical Precipitation for Nitrogen Removal from Old Landfill Leachate
Biological treatment SBBR MAP struvite
2009/2/25
The study reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological...
Biological Removal of Impurities from Textile Industry Wastewaters: An Assessment
textile industry water wastes biodegradation activated sludge
2009/2/8
Textile wastewaters (WW) contain specific impurities that impede their biological treatment. Thus, to be treated biologically, they require technological pre-treatment, mostly composition equalisation...
