The present study focused on assessing the groundwater quality of the shallow aquifer in the northeastern Wasit Governorate Iraq. The physicochemical parameters including major ion and anion compositions pH total dissolved solid and electrical conductivity were used to assess the suitability of groundwater quality for drinking purpose by comparing with the WHO and Iraqi standards.
The novel aspect of this work was the characterization of the samples via N 2 adsorption isotherms conducted in parallel on porous materials for the first time in the academic literature. Si was found to be more readily extracted from the framework compared with Al with the mesoporosity of the samples increasing as the Si/Al increased.
magnesium content. Some water constituents can cause severe soil permeability problems like the excessive quantities of sodium or shortages of calcium and magnesium carbonates and bicarbonates under certain conditions in addition to pure water i.e. low salt water which rapidly dissolve all sources of calcium

90% of Iraq& 39;s electricity generation facilities had also been destroyed. On Nov. 28th 2001 we called the United Nations Iraq sanctions office and learned that $1 Billion of supplies to reconstruct electric generation has been "on hold" since nearly a year. Two years later Washington was blocking $5 billion of approved imports.
In this study GIS-based Multi-Criteria Decision Approach MCDA is used to identify suitable lo ions to use groundwater for irrigation purposes in Salah-Al-Din Governorate 180 km to the North of Baghdad capital of Iraq republic. Various criteria are adopted including Electrical Conductivity EC Power of Hydrogen pH Sodium percentage Na% Sodium Adsorption Ratio SAR Magnesium ...
The cave site of Shanidar is lo ed in the Zagros Mountains of Kurdistan in Iraq. It was excavated between 1957-1961 by Ralph Solecki and his team from Columbia University and yielded the first adult Neanderthal skeletons in Iraq dating between 60-80 000 years BP.
adsorption. The principle difference between both is the nature of the sorbent used. In the absorption system the sorption process takes place between liquid sorbent and gaseous refrigerant substances and the refrigerant undergoes a change in its phase while in the adsorption system the sorption process takes place between solid
