The Approximation of Continuous Function Using Projection Operator

In this research, we study the projection operator linked with Chebyshev polynomials that has an important role in finding the best approximation polynomials for a function on the interval. we also use an operator as a useful method in defining best approximation polynomial for Continuous Function on the interval writhen defined condition, The operator is used in zero points of the Chebyshev polynomials and we proved that norm of the operator in minimum.

comparison of complications of sharp curettage and vacuum aspiration for first trimester abortion

Abortion is the most common complication of early pregnancy, so that should be effectively managed with safe and appropriate procedures. Surgical evacuation of the uterus for management of first trimester abortions usually involves vacuum aspiration or sharp curettage. Objective:To compare the complications of electric vacuum aspiration (EVA) and sharp curettage (D&C) for first trimester abortions, and detect the method that ensure more safety and efficacy. Subjects and methods: The study included one hundred women with incomplete abortion, missed abortion or blighted ovum, gestational age less than 12 weeks whom come to the department of obstetrics and gynecology at Al-Assad university hospital in Lattakia , Syria between 1 July 2013 and 1 July 2014. They were allocated into two groups, group A (n = 50) underwent EVA and group B (n=50) underwent D&C. The procedures were performed using the general anesthesia. We excluded: febrile state, clotting disorders, sever medical and surgical complications, unstable hemodynamic state. Results: Clinical characteristics were similar in the two groups. There were no reports of maternal deaths, cervical laceration, uterine perforation or blood transfusion recorded in the two groups. Blood loss was greater with D&C group than with EVA group (0.001). need an analgesic was greater with D&C group than with EVA group (0.002). Duration of operation and hospitalization was significantly shorter with EVA group than with D&C group. The two groups were similar in success procedure. Conclusion: The efficacy of EVA was the same as that of D&C in successful the procedure, but pain and blood loss were experienced more in the D&C group.

Causes of first trimester bleeding in Alasad University Hospital patients during 2013-2014

A study was done about bleeding in first trimester of pregnancy including 816 patients from 3104 pregnant women(26.28 %) . The causes was abortion ( %96.07), ectopic pregnancy (%2.69) and hyditidiform mole (%1.22). In patients with abortion 486 patients suffered from pain with bleeding(%61.09) and when happeded together the rate of complete abortion elevated . (%78.18) had early abortion whereas(%21.81) had late abortion.The most common high risk factors in patients with abortion were poor and low level of life also the age -35 40 years old(%47.44). The tubal ectopic pregnancy was the most common and the privious pelvic operation is one of the most important high risk factors for ectopic pregnancy. All patients with ectopic pregnancy had amenorrhea with low or no changes in β- HCG levels and (%86.36) had abdominal pain with changes and pain in the cervixs. 16 patients (%72.72) needed surgical therapy.

Medical care provided to Abortion and post abortion cases in Maternity University Hospital in Damascus – Descriptive study

Abortion is the most common complication during pregnancy up to 25% of clinically diagnosed pregnancies .It is the most common cause of maternal morbidity and mortality in the first trimester. There is need to evaluate the quality of the services provided to the patients and to what extent it is compatible with new evidence based practices subsequently working on its development and updating This study aims at describing medical services provided to the patients both during and after abortion in the Maternity University Hospital.
