This report describes the surgical-orthodontic treatment procedures of a patient with condylar hypoplasia. Condylar hypoplasia is a major factor in any facial abnormality in a growing child. This case report describes a patient with a facial anomaly with an acquired unilateral condylar hypoplasia. His asymmetry was corrected by using functional therapy for the correction of muscle tonus and distraction osteogenesis for lengthening the mandibular ramal height. Fixed orthodontic appliances were used for conventional orthodontic therapy and final occlusal adjustment.
The effect of conductivity, dielectric constant and their variations with respect to frequency on the amplitude and phase of the wavetilt was investigated. The phase of wavetilt appeared to be more sensitive to change of frequency at low frequencies. The results showed the effect of dispersion on the sensitivity of wavetilt under modeled earth conditions.
In this paper, the performance of turbo coded signals are investigated over Wireless Local Loop (WLL) environment with no side information on the phase noise and no channel state information (CSI). We assume that the transmitter and the receiver are point-to-point microwave links, separated by WLL which is modelled as 1+Dn/Partial Response Microwave Channel (PMRC) with realizable and practical medium parameters. Here, the combined effects of the nonideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered, each modelled by the Rayleigh and Tikhonov distributions respectively. As a . . .n example, the jitter performance of turbo coded signals are evaluated over 1+D/PRMC with effective signal-to-noise ratio in the carrier tracking loop, fading parameter, iteration number and frame data block size. The numerical results clearly demonstrate the error performance degradation due to both amplitude fading and phase noise process
A research about the technology management practices and draw technology management profiles of machine manufacturing industry in Turkey was presented. The research provided a means to assess the effectiveness of the critical technology management activities, and identify areas of improvement. It intended to diagnose and identify the actual reasons for deficiency in management of technology processes.
System-dynamic simulation game for energy sector of Turkey was discussed. System-dynamic modeling helps to simulate the results of the decisions before actually implimenting them. It was found that this system can help in solving decision problems in energy investments.
The megatrends in Turkey were discussed. Media content analysis by MORN was done using factor-analytic approach. Results showed that most of the respondents disagree on the trends obtained from Germany and Austria. It was also found that respondents believe that technological developments cause social problems such as unemployement and energy consumption rationing.
In this paper an improved version of the previously presented ECR (Extended Control Regions) targeting method is proposed, where the system data is first pre-processed and subdivided into clusters, and then one artificial neural network is assigned to each such cluster. Furthermore, an analytical criterion for determining the region of the current system state during targeting is introduced, whereas in the original ECR method the region information was hidden in the neural networks. Simulation results on several chaotic systems show that this modified version of the ECR method reduces the average reaching time and in general also th . . .e training time of the neural networks
A modified technique of vein grafting for vascular reconstruction that facilitates surgical procedures by preventing size, diameter, and length discrepancies as well as twisting, is presented. The distal end of the harvested vein graft is ligated, and the graft is inflated with heparinzed saline. The determination of the small side branches makes ligation easier. Gentle hydrostatic dilation relieves spasm, straightens the vein, and ligation of the proximal end is then performed under tension. As the vein inflated with heparinzed saline achieves maximum size, diameter, and length without torsion, the sausage-like graft can easily be . . .interposed in tunnels, passages, or soft tissues between recipient vessel gaps. As the graft is under adequate tension, it is easy to determine its appropriate length, size, and diameter. Suturing is carried out using double approximating clamps. The graft will not twist or kink, as it is anastomosed under tension. The clamps are left in place until completion of the distal and proximal anastomoses. The distal clamp is released first. With this simple modification, most of the technical difficulties, such as length, size, and diameter discrepancies, and twisting and torsion of the graft, can be eliminated. The risk of failure due to vascular thrombosis at the anastomotic sites is lowered, as the vein graft is filled with heparinzed saline, and no blood flow is permitted during the reconstruction. The surgeon also saves time with this easy, simple, and feasible method
A system dynamic modeling of conflicts within Turkey and between Turkey and her neighbours were presented. The dynamic structure of international and domestic conflict was explored by defining population, technology, military expenditure and income equality level. It was observed that the system dynamics was the best tool to examine the major processes that generate conflict and warfare within and between nations.
