In this paper, we present and discuss a an optical surface plasmon resonance （SPR） path to extend the enhancement of the resolution of sensor. Basically, our approach is to combine bi-metamaterial layers to design the SPR sensor. The calculation shows that the proposed SPR sensor structure has a preference over the conventional SPR sensors and bimetallic SPR sensors since it gives a much sharper reflectance dip and can achieve considerable sensitivity improvement when compared to the recently reported investigations. The effects of the metamaterial permittivity, permeability, and thickness on the reflectance curve are studied. It is also seen that metamaterial layers improve the field of the proposed SPR structure, which may provide a novel tool to significantly enhance the sensitivity and resolution of the sensors.

Earth has been documented as a natural territory for fungi which cover individual kingdom with evolution. In subsequently vertebrates developed keratin which was a part of life as a structural aspect. Few moulds have skilled to digest keratin and crop up from soil and wastewater habitats. They take part as a keratinolytic agent in the purification of α-keratins with an incidence of disulphide and hydrogen bonds which are improperly biodegradable. The best moulds genera to decay of keratin are Microsporum, Trichophyton and Epidermophyton. The presences of these genera are open health issues in developing countries where they cause the mortal mycotic contagion. The reason behind this is perceived to be the poor hygienic environment and socioeconomic behaviour among people. The present review is a compilation of updated information concerning the nature of these keratinolytic moulds and abundances of most contributed developing countries including India.

Intramedullary interlocking nailing is the gold standard for treatment of tibial shaft fractures. The growing use of intramedullary nailing has resulted in an increased number of tibial nailing in daily clinical practice. Despite adequate surgeon experience, tibial nailing is not without complications if proper techniques are not followed. A case of iatrogenic talar neck and medial malleolus frac- tures during intramedullary nailing of tibia in a 24-year-old male is reported. It is believed to be caused by forceful hammering of insertion zig with foot dorsiflexed. To the best of our knowledge, no such case has been reported in the literature. It is possible to reduce the risk of this complication by adoption of preventive measures.

Objective: The objective of this study was to compare the efficacy of 0.5% ropivacaine and 0.25% bupivacaine for parasternal intercostal block for postoperative analgesia in children undergoing cardiac surgery. Design: A randomized, controlled, prospective, double blind study. Setting: A tertiary care teaching hospital. Participants: One Hundred children scheduled for cardiac surgery through a median sternotomy were divided into 3 groups of at least 33 children each, receiving either ropivacaine, bupivacaine or saline (control). Interventions: A bilateral parasternal block performed either with 0.5% ropivacaine or 0.25% bupiacaine or 0.9% saline with 5 doses of 0.5 mL on each side in the 2nd to 6th parasternal intercostal spaces 1 to 1.5 cm lateral to the sternal edge, before sternal wound closure. Measurements and Main Results: The time to extubation was significantly less in children administered the parasternal blocks with ropivacaine or bupivacaine compared to the saline (control) group. The pain scores were lower and comparable in the ropivacaine and bupivacaine groups compared to the saline group. The cumulative fentanyl dose requirement over a 24-hour period was higher in the saline group than the ropivacaine (p < 0.001) and bupivacaine group. No side effects were observed in any of the children. Conclusions: Parasternal blocks either with ropivacaine or bupivacaine appear to be a simple, safe, and useful technique for supplementation of postoperative analgesia in children undergoing cardiac surgery with a median sternotomy.

Purpose: Defects aro und the distal one third of the leg and ankle are difficult to man age by con servative measures or simple split thickness skin graft. Distally based peroneus brevis muscle flap is a well described flap for such defects. Methods: This is a retrospective analysis conducted on 25 patients with soft tissue and bony defects of distal third of lower leg and an kle, which were treated using distally based per on eus brevis muscle flap from January 2013 to January 2018. Information regarding patient demographics, etiology, size and location of defects and complications were collected. All patients were followed up for at least 3 months after surgery. Results: There were 21 males and 4 females with the mean age of 39 (5-76) years. The most comm on cause of injuries was road traffic accident, followed by complicated open injury. The average size of defects was 20 (4—50) cm^2. The mean operating time was 75 (60-90) min for flap harvest and inset. We had no patient with complete loss of the flap. Five patients (20%) had marginal necrosis of the flap and two patie nts have graft loss due to un derlyi ng hematoma and required sec on dary split thickness skin grafting. Conclusion: The distally based peroneus brevis muscle flap is a safe optio n w 让h reliable an atomy for small to moderate sized defects following low velocity injury around the ankle. The commonest complication encountered is skin graft loss which can be reduced by primary delayed grafting.

In this paper, a parallel fuzzy proportional plus fuzzy integral plus fuzzy derivative （FP＋FI＋FD） controller is proposed. It is derived from the conventional parallel proportional-integral-derivative （PID） controller. It preserves the linear structure of a conventional parallel PID controller, with analytical formulas. The final shape of the controller is a discrete-time fuzzy version of a conventional parallel PID controller. Computer simulations are performed to evaluate the performance of the FP＋FI＋FD controller for setpoint tracking and load-disturbance rejection for some complex processes, such as first- and second-order processes with delay, inverse response process with and without delay and higher order processes. Also, the performance of the proposed fuzzy controller is evaluated experimentally on highly nonlinear liquid-flow process with a hysteresis characteristic due to a pneumatic control valve. The simulation and real time control is done using National InstrumentTM hardware and software （LabVIEWTM）. The response of the FP＋FI＋FD controller is compared with the conventional parallel PID controller, tuned with the Ziegler-Nichols （Z-H） and /~strSm- H^gglund （A-H） tuning technique. It is observed that the FP＋FI＋FD controller performed much better than the conventional PI/PID controller. Simulation and experimental results demonstrate the effectiveness of the proposed parallel FP＋FI＋FD controller.
