Objectives of this project were to study the effect of 60% crude alcoholic extract of the seeds of cyperus esculentuson induced endometritis in the mice . The plant of cyperus esculentuswas extracted by preparing Alcoholic extract 60% . One hundred microliters of saline containing Escherichia coli (104cfu) was used to induce endometritis, by a single intracervicallyinjection, and endometritis developed after 2 days from injection. The mice were divided into five groups, The first group were treated with alcoholic extract of cyperus esculentusextract 150mg/kg body weight, the second group was treated with a daily 3mg per kg body weight of gentamicin given intra peritoneal,The third group was treated by 75mg/kg of cyperus esculentusextract and 1.5mg/kg of gentamicin, The fourth group was treated by distilled water given orally by stomach tube, treatment of mice in these groups continued for 14 days while the the fifth group was (negativecontrol group). The results of the packed cell volume (P.C.V.)%, hemoglobin (Hb)g/dL of mice in alcoholic extract group(T1)after 7 days of treatment showed significant improvement as compared with mice in induction group (T4) andafter 14 days of showed no significant increase (P≤ 0.05)as compared with mice in control group (T5). While in gentamicin(T2) treated group after 7 and 14 days of treatment showed significant decrease (P≤ 0.05) as compared with mice in (T4) and (T5) , furthermore the mice in alcoholic extract and gentamicin treated group(T3) after 7 and 14 days showed significant decrease as compared with (T5) in addition showed significant increase (P≤ 0.05) as compared (T2). Total white blood cell count and all differential white blood cell of alcoholic extract group(T1)after 7 days of treatment showed significant improvement as compared with (T4) and after 14 days of treatment showed no significant increase (P≤ 0.05)as compared with (T5). While the (T2)after 7 and 14 days of treatment showed significant decrease (P≤ 0.05) as compared with (T4) and (T5) while the eosinophil percentage showed significant increase (P≤ 0.05) as compared with mice in (T5). While (T3)after 7 days showed no significant important as compared with control group, but after 14 days of treatment showed significant decrease as compared with control group, in addition showed significant increase (P≤ 0.05) as compared with mice in (T2). the results of fertility index shown in alcoholic extract treated group (T1) and alcoholic extract and gentamicin treated group (T3) was increased as compared gentamicin treated group (T2). The results of body weight and uterine weight showed significant increase (P≤ 0.05) in alcoholic extract treated group as compared with control group and mice in gentamicin group.After 7 and 14days of induction with E.coli intrauterine infection revealed presence of inflammatory cellswithin the endometrial glands and surrounding glands, glandular epithelium is degenerating and the lumen contains cellular debris) , while the groups that treated with both extract and gentamicinshowed cellular debris within the glandular endometrium. group treated with the extract for 14days noticed cellular debris within the glandular endometrium and few inflammatory cells around the endometrial glands. Thegroup treated with Gentamicin for 14days of inductionshowed also degenerating of glandular epithelium and aggregates of inflammatory cells surrounding degenerating glands and presence of hemosiderin around glands, the control group showed normal uterine tissue
Surfaces quality is one of the most specified customer requirements for machine parts. The major indication of surfaces quality on machined parts is surface roughness. The research aim is to study the cutting conditions and their effects on the surface roughness. This paper utilizes regression models to predict surface roughness over the machining time for variety of cutting conditions in turning. In the experimental part for turning, different types of materials (Aluminum alloy, Copper alloy, and Gray cast iron) were considered with different cutting speed ( ) and feed rate ( ). A mathematical Model depending on statistical-mathematical method between surface roughness (Rz ) and cutting condition ( , ) were derived, for the three materials

Show MoreThis work has been done with using of epoxy resin mixed with Granite powder were weighted by percent volume (5,10,15, and 20)%and then mixed with epoxy polymer to compose polymer composite. Hand lay-up technique is used in fabrication of the composite samples. Hardness test was carried out for the proper samples in both normal condition and after immersion in HCL (1 M and 2 M) solutions for periods ranging up to 10 weeks. After comparing the results between the polymer and their composite, the hardness increased with increasing Granite weight percent, it was found that Hardness were greater for the composites before immersion compared with their values after immersion.
In this research, hand lay- up technique is used to prepare samples from epoxy resin reinforced with multi- walled carbon nanotubes in different weight fractions (0, 2, 3, 4, 5) wt%. The immersion effect by sodium hydroxide solution (NaOH) at normality (0.3N) for a period of (15 days) on the thermal conductivity of nanocomposites was studied, and compared to natural condition (before immersion). The thermal conductivity of epoxy nanocomposites specimens were carried out using Lee’s disk method. The experimental results showed that thermal conductivity increased with increase weight fraction before and after immersion for all specimens, while the immersion effect leads to decrease thermal conductive values compared to thermal conductivi

Semiconductor-based metal oxide gas detector of five mixed from zinc chloride Z and tin chloride S salts Z:S ratio 0, 25, 50, 75 and 100% were fabricated on glass substrate by a spray pyrolysis technique. With thickness were about 0.2 ±0.05 μm using water soluble as precursors at a glass substrate temperature 500 ºC±5, 0.05 M, and their gas sensing properties toward CH4, LPG and H2S gas at different concentration (10, 100, 1000 ppm) in air were investigated at room temperature which related with the petroleum refining industry.
Furthermore structural and morphology properties were scrutinize. Results shows that the mixing ratio affect the composition of formative oxides were (ZnO, Zn2SnO4, Zn2SnO4+ZnSnO3, ZnSnO3, SnO2) ratios ment
ZSM-5 zeolite was synthesis under hydrothermal conditions at 175oC. The synthesis parameters have been investigated to find optimum synthesis method. Firstly, the crystallization time has been investigated to find the optimum crystallization time. Also, the ageing time was studied. The morphology, structure, and composition of the synthesized ZSM-5 zeolite were characterized using scanning electron microscopy (SEM), pH meter, viscometer, and X-ray powder diffraction (XRD). The bulk Si/Al ratio of ZSM-5 zeolite was in the range of 9.5—11.7. The synthesized ZSM-5 zeolite with appropriate ageing time could adjust crystal size and degree of the crystallinity. The crystal size of ZSM-5 zeolite obtained at an agei

To observe the effect of media of the internal pressure on the equivalent stress distribution in the tube, an experimental study is done by constructing a testing rig to apply the hydraulic pressure and three dies are manufactured with different bulging configurations (square, cosine, and conical). In the other part, ANSYS APDL is generated to analyze the bulging process with hydraulic and rubber (natural and industrial) media. It was found that when the media is a rubber, the stress is decreased about 9.068% in case of cosine die and 5.4439% in case of conical die and 2.8544% in case of square die. So, it can be concluded that the internal pressure in the rubber media is much better than in hydraulic media. Also, the force needed for fo
