Background: spontaneous abortion constitutes one of the most important adverse pregnancy outcomes affecting human reproduction, and its risk factors are not only affected by biological, demographic factors such as age, gravidity, and previous history of miscarriage,but also by individual women’s personal social characteristics, and by the larger social environment. Objective:To identifyEnvironmental effects on Women's with Spontaneous Abortion. Methodology:Non-probability(purposive sample)of(200) women, who were suffering from spontaneous abortion in maternity unitfrom four hospitals at Baghdad City which include Al-ElwiaMaternity Teaching Hospital, and Baghdad Teaching Hospital at Al-Russafa sector. Al–karckhMaternityHospital ,and Al-Yarmook Teaching Hospital at Al karckh sector. The data are collected through the use of constructed questionnaire, which included: demographic characteristics, reproductive characteristics, causesof spontaneous abortion ,and Environment domain of quality of life. Data were collected through the use of questionnaire,Study implemented for the period ofFebruary 3rd2013 to April 26th2013. A pilot study was carried out to test the reliability of the questionnaire and content validity was carried out through the 20 experts. Descriptive and inferential statistical analyses were used to analyze the data. Results:The results of the study revealed that (26.5%) ofwomen their average age (25-29) years, and the their body mass index (48%) at normal weight, (27.5%) of study sample was graduated from primaryschool,(25%) of their husband graduated from institute or college, (80%) of samples are housewives, (54.5%) of their husband employed,(48%) of study sample is within low category of socioeconomic status, and about the reproductive information (66%) of women were primi and multi gravid, (25%) of women have two birth, (52.5%) have previous one abortion. There are association betweenoccupation status of husband, and the nature of workof wife and husband with environmental domain, and with reproductive parameters it presents association between women's gravida and environmental domain. Conclusions:There are significant association between environment domain of andwomen’s sociodemographic at (occupation status of husband, and the nature of workof wife and husband) andwith reproductive parameter at (gravida). Recommendations:The study recommendedconductstructured teaching programmed (STP)toantenatal mothers with history ofmiscarriage conducted by the investigator included meaning, causes, and prevention of miscarriage. It also includes the do’s and the don’ts during 1st trimester of pregnancy, andcollaborative action can Ministry of Health take in distribution of awareness for women towards the problem by conducting booklet or lecture about miscarriage

Two different composite materials were prepared by stir casting method of AA 6061 alloy as a matrix reinforced with two addition different ceramic materials Al2O3 and B4C of grain size 20 µm by 2.5, 5, 7.5 and10% in weight. The composite material with aluminum alloy as a matrix possesses a unique mechanical properties such as: high specific strength and hardness, low density, and high resistance to corrosion and friction wear. This composite is widely used in automotive parts space and marine applications.
Pin-on-disc technique was used to calculate the wear rate for each addition of Al2O3 and B4C particles. Rockwell hardness test and

The dynamical behavior of a two-dimensional continuous time dynamical system describing by a prey predator model is investigated. By means of constructing suitable Lyapunov functional, sufficient condition is derived for the global asymptotic stability of the positive equilibrium of the system. The Hopf bifurcation analysis is carried out. The numerical simulations are used to study the effect of periodic forcing in two different parameters. The results of simulations show that the model under the effects of periodic forcing in two different parameters, with or without phase difference, could exhibit chaotic dynamics for realistic and biologically feasible parametric values.
Wellbore stability is considered as one of the most challenges during drilling wells due to the
reactivity of shale with drilling fluids. During drilling wells in North Rumaila, Tanuma shale is
represented as one of the most abnormal formations. Sloughing, caving, and cementing problems
as a result of the drilling fluid interaction with the formation are considered as the most important
problem during drilling wells. In this study, an attempt to solve this problem was done, by
improving the shale stability by adding additives to the drilling fluid. Water-based mud (WBM)
and polymer mud were used with different additives. Three concentrations 0.5, 1, 5 and 10 wt. %
for five types of additives (CaCl2, NaCl, Na2S
