Background: Fetal macrosomia represent a
continuing challenge in obstetrics and increasing in
it's occurrence as well as it is associated with maternal
and perinatal complications.
Objective : To determine the maternal and perinatal
outcome related to fetal macrosomia.
Design: A prospective case control study.
Patients and methods) :10th March-31st May, 2006
A prospective case control study had done over the
period from 10th March to 31st May, 2006 in Al-Batool
maternity teaching hospital in Mosul city .The study
group consisted from 633 singleton alive newborns
with gestational age ≥37weeks weighing 4000 grams
and heavier and mothers of these newborns compared
with control group which consisted from 4155
singleton alive newborn with gestational age
≥37weeks weighing 2500-3999 grams and mothers of
these newborns .The obstetrical outcome variables
which compared between the two groups include mode
of delivery, indication of caesarean section and
maternal and perinatal complications.
Results :
Macrosomic newborns (≥4000grams) delivered in this
study account for (12.45%) of total deliveries.
Newborns with a birth weight of ≥4500grams
constitute 2.65% from all deliveries .Male Newborns
(65.24%) was higher and statistically differed among
the study group (p value=0.001).
Instrumental vaginal delivery (P value=0.010,Odd
ratio :2.12, 95 %CI :1.19-3.76) and cesarean section
delivery (P value=0.000,Odd ratio:1.63, 95 %CI :
1.34-1.98), mainly the emergency cesarean section
(18.79%), were significantly different among the
study group .Failure of progress of labour and
cephalopelvic disproportion were the main indications
in study group and showed statistical significant
difference between the two groups.
Among the study group, there was neither maternal
death nor uterine rupture but there was higher
occurrence of postpartum hemorrhage, genital tract
trauma and shoulder dystocia which were significantly
different when it compared with control group .Erb's
palsy was the main perinatal complication and was
statistically different among macrosomic group (P
value=0.000) .
Conclusion: Fetal macrosomia was associated with
higher rate of instrumental vaginal delivery and
caesarean section mainly due to failure of progress of
labour and cephalopelvic disproportion .There were
higher rate of postpartum haemorrhage, genital tract
trauma as well as shoulder dystocia with neither
maternal death nor uterine rupture in study group .
Among macrosomic newborn, Erb's pulsy was the
main perinatal complication

In this study, a genetic algorithm (GA) is used to detect damage in curved beam model, stiffness as well as mass matrices of the curved beam elements is formulated using Hamilton's principle. Each node of the curved beam element possesses seven degrees of freedom including the warping degree of freedom. The curved beam element had been derived based on the Kang and Yoo’s thin-walled curved beam theory. The identification of damage is formulated as an optimization problem, binary and continuous genetic algorithms
(BGA, CGA) are used to detect and locate the damage using two objective functions (change in natural frequencies, Modal Assurance Criterion MAC). The results show the objective function based on change in natural frequency i

Solid dispersion (SD) is one of the most widely used methods to resolve issues accompanied by poorly soluble drugs. The present study was carried out to enhance the solubility and dissolution rate of Aceclofenac (ACE), a BCS class II drug with pH-dependent solubility, by the SD method. Effervescent assisted fusion technique (EFSD) using different hydrophilic carriers (mannitol, urea, Soluplus®, poloxamer 188, and poloxamer 407) in the presence of an effervescent base (sodium bicarbonate and citric acid) in different drug: carrier: effervescent base ratio and the conventional fusion technique (FSD) were used to prepare ACE SD. Solubility, dissolution rate, Fourier transformation infrared spectroscopy (FTIR), PowderX-ray diffraction

This paper reports test results and describes a numerical investigation of the effectiveness of using carbon fibre reinforced polymer (CFRP) fabrics for strengthening concrete cylinders that have been undamaged and damaged due to heating under preload. The purpose of this research was to investigate whether there is any difference in the performance of CFRP-wrapped cylinders if the wrapping is done under preload, and those for which neither heating, cooling nor wrapping was done under preload. The cylinders were exposed to 30% of maximum load at ambient temperature during heating and cooling before being wrapped under preload. Of 18 Ø 100 × 200 mm identical cylinders, 6 were left as control samples without heating, 12 were exposed t

The present work aimed to study the efficiency of nanofiltration (NF) and reverse osmosis (RO) membrane for heavy metal removal from wastewater and study the factors affecting the performance of these two membranes: feed concentrations for heavy metal ions, pressure, and flow rate. The experimental results showed, heavy metals concentration in permeate increase with raise in feed concentrations, decline with increase in flow rate. The raise of pressure, heavy metals concentration decreases for RO membrane, but for NF membrane the concentration decrease and then at high pressure increase. The rejection percentage for chromium in NF and RO is 99.7% and 99.9%, for copper is 98.4% and 99.3%, for zinc is 97.9% and 99.5%, for nickel is 97.2% and
