The Helianthus tuberosus , it is one of the important Tuberous plants . at present time Where this plant
was used in the study , Precisely the juice fruit of Helianthus tuberosus , as were used widely in promoting
immune system , stimulate blood circulation, controlling cholesterol , blood pressure, diabetes, muscle ,
preservation of food , Antibacterial , the Beautify skin and Biofuels. This study conducted on juice fruit
Helianthus tuberous . it taken from different areas in Baghdad / Iraq . after Buy them from the local market
, washed, dried and squeeze . this study aimed to identify the chemical compounds and trace elements in
the Helianthus tuberosus juice using tests chemical differents , usage a measurement technique (GC-MS)
,and the FTIR spectrum. and their impact on the liver function of domestic birds and species of
microorganisms , The study is giving that the juice of the fruit Helianthus Tuberosus is Acidic nature and
near from the value acidic for water , The study showed that the extract contains a group of carbohydrate
compounds, phenol compounds, tannins , resins, flavonoids, alkaloids, turbines, unsaturated fatty acids,
polymers. and the Inulin compound. The Study showed the ability of juice Helianthus Tuberosus in
concentration of 15%, increasing stimulate of SGPT levels and SGOT in serum (p <0.01), while the levels
of ALP, LDL, TG were decreased (p <0.05), The study shows extracting of phenolic compounds in fruit
juice Helianthus Tuberousus when TLC and HPLC used a mixture (water, chloroform , acetic acid) and by
(3: 6: 1) . This mixture had effect on multi pigment (gram pigments) . The effect was more in Gram
positive bacteria (Escherichia coli Pseudomonas aeruginosa, Salmonella typhimurium), but its effect was
less in Gram negative bacteria (Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis).
lastly the study giving , through the quantitative estimate of the chemical elements of the juice of the
Helianthus Tuberosus fruit , contained some important minerals of different concentrations with a capacity
of (ppm).the presence of these elements led to increased enzymatic effectiveness through increased support
for building bone tissue and the process of activating enzymes transfer of oxygen in the blood and increase
the flow of all metabolic processes in the body and that these jobs will give an over view of the work and
effectiveness of the nature activity of some organs of our body.

The main objective of this study was to evaluate the microbiologically
influenced corrosion of carbon steel in water, samples of water taken from Al-Hilla rivers and distill water (control medium ). Corrosion analyses by using (Liner polarization tafel test; weight loss method ; microstructure examination , surface roughness test and X-Ray diffraction analysis) and microbiological analyses by using
(Isolation and identification by using appearance factors microscopic ,culturing factors and biochemical tests for biofilm of corrosion product) are used in this study. The result of corrosion analyses shows the corrosion rates of carbon steel in rivers water are more than that in control water, the microstructure examination and surface roughness tests show increase in roughness of met.al. surfaces which are
under the corrosion medium (rivers water) compared with control medium. The result of microbiological analyses shows the slides that made from the biofilm (product of corrosion) under microscopic appear small bacilli negative gram strain (G-ve) bacteria, where as culturing test shows small colonies with 2.5ìm in diameter of bacteria have mucin appearance and green pigments as well as the result from
biochemical tests; these facts indicate that Pseudomonas aeruginosa bacteria are correlated with the type of corrosion occurring in the carbon steel in the rivers water.

Engineering and Technology Journal, 2008, Volume 26, Issue 4, Pages 458-461

Magnetic fields with two densities (1200 , 3200)gauss experminted on two
kinds of bacteria Escherichia coli and Staphylococcus aureus in Nutrient broth
media . The field subjected for (1,2,3) weeks, and the growth monitored using
optical density (OD) method.
The results shows greatest effects of 3200 gauss than 1200 gauss on bacteria
growth comparing with control sample after third week. The OD resulte of bacteria
Escherichia coli (0.3) with 3200 gauss and (6) with 1200 gauss comparing with
control sample(175.4) and bacteria Staphylococcus aureus (1) with 3200 gauss,
and (10) with 1200 gauss comparing with control sample (174.4).
