Field assessment to the defects of high concrete reservoir in the central area

This research addresses analytica of the faults suffered by high reservoirs with concrete products field study of a number of reservoirs in the central area in Syria, and identifying its defects occurring therein, and proposing solutions to address them.

Use of the soleus muscle flap to cover exposed tibia

The management of lower extremity trauma has evolved over the last two decades to the point that many extremities that would have required amputation are routinely salvaged. The use of transposition muscle is regarded as the optimal method for the treatment of extensive defects of soft tissues in limb traumatology. The aim of the study is to investigate the therapeutic effect of repairing soft tissue defects of mid-tibia open fractures with muscle flap pedicled with medial half of soleus. A retrospective study of our outcome of 10 performed soft-tissue reconstruction of an open tibial wound cases. All these patients were operated using the proposed surgical technique between 2013 and 2015 in AL-ASSAD University Hospital in Lattakia, Syria. The results of this technique of reconstruction are excellent. Medial hemisoleus flap is a valuable option for soft tissue coverage of middle third of lower leg. It does not sacrifice the whole function of the Soleus muscle. Due to its longer arc of rotation, this flap can cover the defects of different size and shape in middle third of leg. The operation is relatively easy. The muscle can fill the narrow cavity and repair the soft tissue defect simultaneously. The donor-site injury is minor.

Design of integrated current sensor BICS for IDDQ Test in CMOS circuits

IDDQ testing techniques are used to detect the physical defects such gate oxide shorts,floating gates and bridging faults, and which happen for the presence of manufacturing faults during the manufacturing processes of CMOS integrated circuits, which cannot be detected by classical logical testing.

Repairing of Steel Pipelines Defects by Using Epoxy Material

This research carries how to do steel pipelines defects repair process by a simple and easy way. At first the region that surrounds the defect is cleaned then the epoxy material is put over the defect after mixing the resin with the hardener well. Epoxy layer dimensions depend on the defect dimensions that exists in the pipe. After that, the specimen is released for a period of time to obtain the setting process. Several types of epoxy were used for preparing series of specimens, which were tested on the pressure set up to estimate the efficiency of this way in the repair, and knowing the pressure values that epoxy layer can carry. A pipe of three holes their radius are equal, was treated by using ALTECO QUICK EPOXY STEEL and the pressure gauge recorded many values that reached 18 bar. The curve, that represents the relationship between the pressure which the epoxy layer carried and its surface area, was drawn. It is found that the most effect factor in the repair process is the specimen preparing and the thickness of the epoxy layer.

A clinical study to evaluate the effect of hyaluronic acid on periodontal infra-bony pockets during four months

Esterified hyaluronic acid has emerged into the periodontal regenerative therapy recently, but there is still a need for more research of its role in periodontal treatments, therefore the goal of this clinical study is to assess its role in the treatment of periodontal infrabony defects in comparison to open curettage.

Determining the Type of Defects in Steel Billet by Ultrasonic Detector Using Straight Beam Probe

This research aims to inspect the defects and discontinuities in steel billet by ultrasonic detector. Straight beam probe used to detect a lot number of imported steel billets that clearly have internal defects. The results showed the possibility of initial detection by straight beam probe, and initial defining the types of defects such as, micro and macro cracks, shrinkage defect, blow holing, inclusion, porosity and others type of internal defects. The experiments showed that if the necessity is defining the size of defects, this requires angle beam probe in addition to straight beam probe.

Virtual Planning Of Surgical Mandibular Reconstruction Using Digital Images and Finite Elements Technic (A Case Study)

Reconstruction of mandibular defects after trauma or tumor resection is one of the most challenging problems facing by maxillofacial surgeons. Few mandibular defects require not just a fixation of an implant, but the reconstruction of the entire mandible. The aim of this study was to design a mandibular prosthesis for a mandibular cancer patient and study its efficacy by stress–strain related mechanical property using finite element analysis (FEA).

Detection of Internal Defects in Steel Billets by Ultrasonic Detector

The present work, aims to inspect by ultrasonic method numbers of imported steel billets, which cause stopping and breaking in the production – lines. The inspection was done by using ultrasonic detector,(echo – pulse method), a straight – beam probe was used as a transducer and receiver, at the same time. The results of inspection showed the possibility of accurate defect determination in steel billets, and also showed a good agreement between the experimental results and the number of stopping and breaking in production in factory, and also the necessity to use that inspection method in the imported billets which cause the continuous breaking in the production – lines.

Histological Evaluation of Magnetic Field Effect on Bone Defect Healing in Rabbits

Bone neoformation is primary importance for the success of maxillofacial surgical treatments. and there are various methods to reach this aim as the physical methods including the usage of electrical , electromagnetic & static magnetic field due to its effect on bone. Aim of study to investigate, the effect of a static magnetic field on the density of bone and osteoblast , without bone graft, With auto graft and With hidroxiapatite.

Damascus University's Experience in Transcatheter Closure of Secundum-Type ASD Using Amplatzer Septal Occluder (ASO)

The aim of this study is to assess results of percutaneous closure of secundumtype atrial septal defect (ASD II) using Amplatzer septal occluders (ASO).
