Study of the Friction Stir Welding For A516 Low Carbon Steel
...Show More Authors

The main objective of present work is to describe the feasibility of friction stir welding (FSW) for
joining of low carbon steel with dimensions (3 mm X 80 mm X 150 mm). A matrix (3×3) of welding
parameters (welding speed and tool rotational speed) was used to see influence of each parameter on
properties of welded joint .Series of (FSW) experiments were conducted using CNC milling machine
utilizing the wide range of rotational speed and transverse speed of the machine. Effect of welding
parameters on mechanical properties of weld joints were investigated using different mechanical tests
including (tensile and microhardness tests ). Micro structural change during (FSW) process was
studied and different welding zones were investigated using optical microscope. The stir welding
experiments conducted that show the low carbon steel can be welded using (FSW) process with
maximum welding efficiency (100.02%) in terms of ultimate tensile strength using best result of
welding parameters (700 RPM, 25 mm/min, tool rotational speed and welding speed respectively and
0.2 mm plunging depth of welding tool) ,there is afirst time that we obtain the efficiency reach to
100.02 % to weld this type of low carbon steel by FSW. The corrosion resistance was measure which
is the new test on the welding by this way and we obtained different result from the result on
traditional welding processes and the result that obtained show the corrosion resistance for this
welding plate better than the base metal. Maximum temperature has been calculated numerically by
using the ANSYS program. The obtained peak temperature is 1102°C, A percentage minimum of the
melting point .

Deterioration Model for Sewer Network Asset Management in Baghdad City (case study Zeppelin line)
...Show More Authors

Asset management involves efficient planning of economic and technical performance characteristics of infrastructure systems. Managing a sewer network requires various types of activities so the network can be able to achieve a certain level of performance. During the lifetime of the network various components will start to deteriorate leading to bad performance and can damage the infrastructure. The main objective of this research is to develop deterioration models to provide an assessment tool for determining the serviceability of the sewer networks in Baghdad city the Zeppelin line was selected as a case study, as well as to give top management authorities the appropriate decision making. Different modeling techniques

Bowel Cleansing Quality in Morning Versus Evening Preparation Regimens for colonoscopy; a Prospective Study
...Show More Authors

Background :Evening preparation for colonoscopy is often unsatisfactory and inconvenient. This study was performed to compare the efficacy of bowel preparation at two different timings: night before and morning of endoscopy and to compare the cecal intubation rate and disturbance of sleep hours between these two groups.
Methods: In this prospective randomized endoscopist- blinded trial, 150 patients were enrolled between March 2010 and August 2011. Patients aged between 18 to 80 years needing colonoscopy were included. Patients with prior bowel surgery, suspected bowel obstruction or those who didn't completely fulfill the preparation instructions were excluded. Patients received polyethyelen glycol electrolyte preparation in a mornin

Anatomical study for leaves and Epidermal properties in Athionema R.BR. species (Brassicaceae) in Iraq.
...Show More Authors

The research included anatomical study of nine wild species of the genus
Athionema R.BR. from BrassicaceA family in Iraq, and these species are:
A.arabicum (L.), A.carneum (Banks et sol.),A. cordifolium (DC.), A.fimbriatum
(Boiss.),A. froedinii (Rech. F.), A. speciosum (Boiss. et Huet), A. syriacum
(Boiss.),A. grandiflorum (Boiss. et Hoh.) , A.trinervium (D.C.).The research
covered the anatomical characteristic of the leaf Epidermis as well as leaves
venation, also transvers sections for leaves were studied ,and revealed that some
anatomical characteristics have taxonomic importance in distinguishing the species.
This research also showed the presence of important variations in internal charecters

Finite element stress analysis study for stresses around mandibular implant retained overdenture MIR-OD
...Show More Authors

Background: It has been well known that the success of mandibular implant- retained overdenture heavily depends on initial stability, retention and long term osseointegration this is might be due to optimal stresses distribution in surrounding bones. Types of mandibular implant- retained overdenture anchorage system and number of dental implants play an important role in stresses distribution at the implant-bone interface. It is necessary to keep the stresses below the physiologic tolerance level of the bone .since. And it is difficult to measure these stresses around bone in vivo. In the present study, finite element analysis used to study the stresses distribution around dental implant supporting Mandible implant retained overdenture Mate
