We report a case of atypical aortic coarctation with severe calcification of the proximal aorta treated by a new extra-anatomical bypass. This 58-year-old woman with coarctation of the infrarenal aorta had thick circular calcifications of the thoracic aorta and stenosis of the subclavian arteries. To control the progressive claudication, we performed a bypass with an externally supported PTFE g...

This paper covers two aspects of Microstrip antenna designs. The first is the analysis and design of single element rectangular Microstrip antenna which operates at the centre frequency of 2. 4 GHz. The second aspect is the design of dual band rectangular microstrip antenna which operates at 2. 4 GHz and 3. 6 GHz used in 802. 11b/g/n and 802. 11y WLAN channels respectively. Both antennas are mo...

We determined whether a PACS-based method (head-lesser trochanter distance [HLD]) better equalized leg length discrepancy (LLD) after primary THA than a conventional method. We retrospectively reviewed 312 patients (379 hips) with osteonecrosis or primary osteoarthritis who underwent primary cementless THA: 198 patients (240 hips) underwent THA using the HLD method, while the conventional group...

The refractive errors of normal, healthy eyes were measured using an indigenously developed Shack Hartmann aberrometer. Measurement was made in both right and left eyes after dilation for a 6mm pupil size. Power vector method was used to represent the sphero cylindrical errors. Analysis was done for astigmatism with the rule, oblique astigmatism and defocus between the right and left eyes of th...

In the design of circular patch antenna, the feed point locations SF=5, SF=6, SF=7 and SF=8 were selected and the simulated results compared and the optimum location adopted and implemented. The best feed point was located at SF=5mm where return loss RL is -37.81dB, followed by SF=6mm with return loss RL of -17.14dB and SF=7mm with return loss RL is -11.38dB. The feed point location at SF=8mm w...

We have studied the performance of two different types of front-end systems for our gamma camera based on Hamamatsu H8500 (flat-panel 64 channels multi-anode PSPMT) with a CsI(Tl) scintillator array. The array consists of 64 pixels of 6× 6× 20mm which corresponds to the anode pixels of H8500. One of the system is based on commercial ASIC chips in order to readout every anode. The others are bas...

We present a case of left anterior descending (LAD) coronary artery aneurysm at the site of previous stent placement 3 years previously. The patient presented with recent worsening of angina. Angiography and 64 slice CT angiography confirmed the presence of 6mm aneurysm of LAD at the site of previous stent involving the origin of diagonal, with thrombus proximal and distal to the stent. This pa...

Selection for increased lean meat yield using Australian Sheep Breeding Values for reduced post-weaning c-site fat depth (PFAT) and increased post-weaning eye muscle depth (PEMD) reduces the oxidative capacity of muscle. Isocitrate dehydrogenase (ICDH) activity and myoglobin concentration were measured in 3178 and 5580 lambs, respectively, to indicate oxidative capacity. In the progeny of sires...

Speakers make effective adaptation to unfavourable articulatory conditions and they successfully compensate for the perturbation. The influence of artificial palate (6mm thick in the region of the alveolar ridge) on the reorganization of articulatory movements when speakers practise pronunciation with the artificial palate is investigated. Five female students of normal articulatory and hearing...

Axisymmetric vibration of an infinite Pyrocomposite circular hollow cylinder made of inner and outer pyroelectric layer of 6mm-class bonded together by a Linear Elastic Material with Voids (LEMV) layer is studied. The exact frequency equation is obtained for the traction free surfaces with continuity condition at the interfaces. Numerical results in the form of data and dispersion curves for th...
