Evaluation of some bioactive effect of phenolic compounds in Costus speciosus rhizome extract
...Show More Authors

This work was evaluated the antioxidant, antibacterial and cytotoxic activity of Costus speciosus rhizomes methanol extract. The FLC analysis showed the presence of five compounds in the methanol extract of C. speciosus rhizomes. These compounds were Quercetin (5.2mg/ml), Rutin (6.02mg/ml), Luteolin, (18.3mg/ml),
Kaempherol, (11.34mg/ml) and Coumarin (1.41mg/ml). The maximum antioxidant activity of the extract was at concentration 1000 μg/ml with free radical scavenging activity approximately 67.5%. It was less than standard ascorbic acid 85.5% and Gallic acid 90% with significant difference (p≤0.05), with no significant difference
in comparison with standard TBA 68.5%. The IC50 of extract was 3093μg/ml, while the IC50 of ascorbic acid, Gallic acid and TBA were (277.2, 364.5 and 601.3 μg/ml) respectively. The extract revealed influential growth inhibition for all bacteria used in this experiment. The extract was moderately effective at concentration 400 μg/ml of extract with inhibitory activity 50.7 % on MCF-7 cell line and IC50 139.1 μg/ml.

THE THERMOELECTRLC POWER OF THE MAGNETLC Fe-Mn-Al COMPOUNDS
...Show More Authors

The thermoelectric power as a function of temperature for the Iron-Manganese-Aluminum, Fe-Mn-Al, alloys for manganese concentrations 0.04, 0.06, 0.08, 0.10 and 0.20 have been investigated in the temperature range 300 K. to 500 K. these results showed that the thermoelectric power coefficient in hot probe measurements showed that the electrons are the majority charge carriers in these alloys.

Abstact:
Nursery is one of educational institution in the process of developing the
social concepts that it includes a quirking the knowledge and experiences that
help the kid to adjust with environment through arrangement words ,
movements and concrete things which are transferred to the kids so as to
realize these concepts .
Social concepts are numbers of words and statements with social nature
which the kids learn through the family or nursery in order to effect their
educational style of independent and helping the others .
The re searcher adopted this theory because of the little studies in the
filed of social concepts in the nursery.
The aims of the study are as following :

Effect of Transverse Internal Ribs on Shear Strength Evaluation of Hollow RC Beams
...Show More Authors

This paper is devoted to investigate experimentally and theoretically the structural behavior of reinforced concrete hollow beams which have internal transverse ribs under effect of shear. The number of the internal ribs is the major variable adopted in this research, while, the other variables are kept constant for all tested specimens. The experimental part includes poured and test of four (200x300x1200mm) beam specimens, three of these specimens were hollow with different locations of internal ribs and one of them was solid. The experimental results indicated that the shear strength are increased (33%) to (60%) for beams containing internal ribs in comparison with reference beam. Also, the change of beam state from ho

Study of the effect of some pregnancy parameters on Malon dialdehyde concentration in pregnant women
...Show More Authors

The present study aimed to evaluate the concentration of Malon dialdehyde (MDA) in pregnant women during different stages of pregnancy (stage of pregnancy, abortion, contraceptives and parity number).The study included (120) blood samples from normal pregnant women in age of the procreating were subdivided into three trimesters of pregnancy (40/group), and (40) samples from non-pregnant women as a control group. The results showed a significant increase in MDA in three stages of pregnancy compared with the control group. The concentration of MDA increased significantly in pregnant women with multipregnancy when compared with pregnant women for the first time, and in pregnant women whom was using contraceptions compared with p

Evaluation of the antibacterial effects of Eucalyptus camaldulensis L., Glycyrrhiza glabra L. and Morus nigra L. extracts against some pathogenic bacteria in vitro
...Show More Authors

This study aimed to test the effect of using different concentrations of three different plants extracts to inhibit the growth of gram negative and gram positive bacteria by two technics. Eucalyptus camaldulensis bark, Glycyrrhiza glabra rhizomes and Morus nigra leaves ethanolic extract at (0,20,30,40 and 50 mg/ml) were used. The antimicrobial activity and the biofilm inhibition assay used with these extracts showed positive effect in inhibiting the growth of bacteria. E.amaldulensis extract showed the higher effect than G. glabra and M.nigra extracts in antimicrobial activity assay, while the effect of E. camaldulensis extract in biofilm inhibition assay was higher than G. glabra that was higher than M. nigra extracts for both gram nega

Study the Contrast of Thermal Expansion Behavior of the Unsaturated Polyester resin (UP) containing Phenolic Bakelite(PF) By Using The Thermomechanical Analysis Technique(TMA)
...Show More Authors

TMA Technique was used to study the behavior of the thermal expansion (α) of the unsaturated polyester resin(UP) containing ratios wt % of different phenolic Bakelite. We can through this technique evaluate the coefficient of linear thermal expansion (α) on the one hand and the glass transition temperature(Tg)  of his other hand of polymer composite prepared .Evidenced from this study that extravagant increases the ratio of phenolic Bakelite in polyester prepared led to a decrease in the Tg and it was observed that there is increase in the values of (α) in low temperture and decrease in high temperture due to transformation of polymeric material from elastic to plastic , and therefore, increase the ratio to 15% phenoli

Antibiofilm Activity of Conocarpus erectus Leaves Extract and Assessment Its Effect on pelA and algD Genes on Multi-drug Resistant Pseudomonas aeruginosa
...Show More Authors

Due to its various resistance mechanisms, Pseudomonas aeruginosa is the most prevalent opportunistic infection that kills hospitalized patients. Thus, therapeutic options become limited. Objective: The study aimed to estimate the antibiofilm effectiveness of Conocarpus erectus leaf extracts against MDR P. aeruginosa isolates and examines pelA and algD gene expression. Subjects and Methods: One hundred-fifty clinical samples were collected from five Baghdad hospitals between September 2021 and January 2022. Samples were grown on different mediums. Despite cetrimide agar's ability to detect P. aeruginosa, only 83 isolates developed at 42°C. VITEK 2 compact system identification followed. This study examined 83 of P. aeruginosa isolates for r
