Dodecanacci superconductor-metamaterial photonic quasicrystal

Using the transfer matrix method, the present paper attempt to determine the properties of the photonic spectra of the Dodecanacci superconductor-metamaterial one-dimensional quasiperiodic multilayer. The numerical calculation is supported by using the transfer matrix method. At first, we analyze the transmission for Dodecanacci quasicrystal for different generations. After that, we analyze the effect of the thickness of the building blocks and the operating temperature. We observed that a vast number of forbidden bandgaps and transmission pecks are developed in its transmission spectra up to a certain generation number of Dodecanacci quasiperiodic sequence. If the generation number increases further, then the bandgaps become wider. According to the obtained results, depending on its generation, this structure can be used as an optical reflector or narrowband filter

Effect of intense pulsed light on immature burn scars: A clinical study

Introduction: As intense pulsed light (IPL) is widely used to treat cutaneous vascular malformations and also used as non-ablative skin rejunuvation to remodel the skin collagen. A study has been undertaken to gauze the effect of IPL on immature burn scars with regard to vascularity, pliability and height. Materials and Methods: This study was conducted between June 2013 and May 2014, among patients with immature burn scars that healed conservatively within 2 months. Photographic evidence of appearance of scars and grading and rating was done with Vancouver Scar Scale parameters. Ratings were done for both case and control scar after the completion of four IPL treatment sessions and were compared. Results: Out of the 19 cases, vascularity, pliability and height improved significantly (P < 0.05) in 13, 14 and 11 scars respectively following IPL treatment. Conclusions: Intense pulsed light was well-tolerated by patients, caused good improvement in terms of vascularity, pliability, and height of immature burn scar

From wheelchair to walking: First case report of post-electrical burn destruction of patellar ligament with its one-stage reconstruction and restoration of function

Electrical burn injury causing bilateral patellar ligament destruction leading to complete loss of knee extension is a very rare injury. In such situation, surgical repair or reconstruction of the patellar ligament becomes necessary to restore knee functions. Here, we present such a case of an 8-year-old boy, whose both patellar ligaments were destroyed throughout its length due to high-voltage electrical injury. His left knee joint cavity was exposed and grossly infected, but the right knee joint cavity was apparently intact. The right-sided patellar ligament was reconstructed with an ipsilateral and looped semitendinosus tendon graft and covered with a medial gastrocnemius musculocutaneous flap. The patient had an uneventful recovery, and full range of motion in the right knee joint along with good bipedal locomotion was achieved successfully
