The study of physical and chemical properties of wells water in district of Samarra
...Show More Authors

The Study was achieved adjectives physical and chemical water wells in the district of
Samarra , where a study has 42 sample groundwater in different regions of the judiciary
randomly distributed all over the judiciary and examined in vitro.
The study showed that the quality of groundwater in the general area of study
Kipritateh punctuated Klordih water quality and other quality Bicarboonatih.
Varied the key components of groundwater in the study area in concentrations
between periods of rain and drought, especially because of the cation ion exchange processes
as well as mitigation as a result of filtering rain water and dominated the calcium ion,
followed by sodium.
As for the negative ions has dominated ion sulfate, followed by chloride on the rest of
the ions as a result of melting rock Gypsum CaSo4.2H2O which have the ability to melt into
the water as the melting of this layer with water leads to high salinity due to increased ion
concentration sulfates as they reach the amount of dissolved salts to more than 15,000 mg / l
and in this case the water becomes unfit for agricultural use, but for the secondary ions
deemed to nitrate ion secondary ions of the most important wells in the study area has
exceeded the permissible limits Iraqis and internationally.The study showed that the majority of groundwater within the study area is not
suitable for various uses Kalshrb for humans and animals, agriculture and industry
classifications used by the internationally recognized, but some of them can be used after
treatment and for specific purposes.

Surface Photometry and Morphology Properties of Spiral Galaxies: NGC4725, NGC4639 as Case Study
...Show More Authors

In this study, two active galaxies (NGC4725, NGC4639) have been chosen to study their morphological and photometric properties, by using the IRAF ISOPHOTE ELLIPS task with griz-filters. Observations are obtained from the Sloan Digital Sky Survey (SDSS) which reaches now to the DATA Release (DR14). The data reduction of all images (bias and flat field) has been done by SDSS Pipeline. The surface photometric investigation was performed like the magnitude. Together with isophotal contour maps, surface brightness profiles and a bulge/disk decomposition of the images of the galaxies, although the disk position angle, ellipticity, and inclination of the galaxies have been done. Also, the color of galaxies was studied, where chromatic distribution

Determining the concentrations of radon and the rate of annual effective dose in some types of drinking water available in the Iraqi markets
...Show More Authors

           In this research, radon concentrations in some types of healthy drinking water samples available in Iraq's market were measured using a technique called Durridge RAD-7-H2O with closed loop. Then the rate of annual effective dose in human taken this water is determined.

          It was found that, radon concentrations in studied samples ranged between 1.2 Bq.m-3 to 142 Bq.m-3. The results of the radon concentrations and the rate of annual effective dose for drinking water samples were significantly lower than the USEPA and WHO recommended limits that equal 500 Bq/m3 and 1 mSv/y resp

...Show More Authors

The most significant water supply, which is the basis of agriculture, industry and human and wildlife needs, is the river. In order to determine its suitability for drinking purposes, this study aims to measure the Water Quality Index (WQI) of the Tigris River in the Salah Al-Din Province (center of Tikrit), north of Baghdad. For ten (9) physio-chemical parameters, namely turbidity, total suspended sediments, PH, electrical conductivity, total dissolved solids, alkalinity, chloride, nitrogen as nitrate, sulphate, and then transported for examination to the laboratory, water samples were collected from 13 locations along the Tigris river. Using the weighted arithmetic index method, the WQI was measured and found to be 105,87 in up-stream, wh
