Background: Women with previous two or
more caesarean deliveries are usually
managed by elective cesarean section to avoid
the possible risks of labor.
Objective: To compare the relative risks of
maternal and fetal outcomes in emergency
versus elective previous two or more
caesarean deliveries
Design: Randomized prospective clinical
study
Setting: Al-Elweya Maternity Teaching
Hospital, from 1st of March to 31st of
September 2008.
Methods: The study groups, those who had
previous two or more caesarean deliveries,
were included from the hospital admissions.
The 1st group (102 women) presented in labor
and was managed by caesarean delivery as
soon as it was possible. The second group (78
women) was admitted for elective cesarean
delivery.
The main maternal outcomes were intra
operative complications, including
hysterectomy, scar dehiscence, bladder
injuries, uterine and internal iliac arteries
ligation, and blood transfusion. Postoperative
maternal outcomes were severe morbidity
including bleeding, fever, urinary tract
infection, blood transfusion, the need to
Intensive Care Unit admission and
readmission. The fetal outcomes measures
were Apgar score at one and five minutes,
respiratory distress syndrome (RDS),
admission to the neonatal intensive care unit
and fetal loss up to hospital discharge.
Results: Both groups were comparable in
demographic, social and past obstetric history
characteristics. Intra operative complications
showed significant difference in bowel
adhesions (RR 0.35, 95% CI 0.14- 0.88), and
blood transfusion (RR 0.51, 95% CI 0.28-
0.94). There was statistical significant
difference in the mobilization time 7.2 hours
and 9.3 hours in emergency and elective
groups respectively (p= 0.0009), also in
feeding time, it was shorter after emergency
caesarean section (P=0.0224), and in the
hospital stay 24.6 and 32.6 hours respectively
(p=0.0001). There was no statistical difference
in post operative complications. Fetal
outcomes showed no statistical significant
difference in fetal loss, respiratory distress and
readmission.
Conclusion: Women with previous two or
more caesarean deliveries can wait until
starting labor for doing cesarean delivery
without increasing risks to the mother and
fetus.

A fast laser texturing technique has been utilized to produce micro/nano surface textures in Silicon by means of UV femtosecond laser. We have prepared good absorber surface for photovoltaic cells. The textured Silicon surface absorbs the incident light greater than the non-textured surface. The results show a photovoltaic current increase about 21.3% for photovoltaic cell with two-dimensional pattern as compared to the same cell without texturing.
In this research, the nonparametric technique has been presented to estimate the time-varying coefficients functions for the longitudinal balanced data that characterized by observations obtained through (n) from the independent subjects, each one of them is measured repeatedly by group of specific time points (m). Although the measurements are independent among the different subjects; they are mostly connected within each subject and the applied techniques is the Local Linear kernel LLPK technique. To avoid the problems of dimensionality, and thick computation, the two-steps method has been used to estimate the coefficients functions by using the two former technique. Since, the two-

Aqueous Two Phase System (ATPS) or liquid-liquid extraction is used in biotechnology to recover valuable compounds from raw sources. In Aqueous Two-Phase Systems, many factors influence the Partition coefficient, K, (which is the ratio of protein concentration in the top phase to that in the bottom phase) and the Recovery percentage (Rec%). In this research, two systems of ATPS were used: first, polyethylene glycol (PEG) 4000/Sodium citrate (SC), and the second, PEG8000/ Sodium phosphate (SPH), for the extraction of Bovine Serum Albumin (BSA). The behavior of Rec% and K of pure (BSA) in ATPS has been investigated throughout the study by the effects of five parameters: temperature, concentration of polyethylene glycol (P

Corrosion of Zn-Ni alloy coatings on stainless steel 316 SS in a chloride-sulfate bath with the addition of either triethanolamine or sucrose was examined. A constant cathode potential was used to deposit zinc-nickel alloys, while cyclic voltammetry and potentio-dynamic polarization were used to measure corrosion. In addition, scanning electron microscopy was utilized to analyse Zn-Ni alloy coating surface layers formed with¬out and with additives. The outcomes discovered that the corrosion resistance of Zn-Ni alloy coat¬ings in 3.5 % NaCl solution was highly influenced by adding triethanolamine or sucrose. Decreasing the Zn:Ni molar ratio led to an increase in corrosion resistance. All Zn-Ni alloy coatings were superior to pure Z
