BaTiO3 thin film has been deposited on Si(100) substrate using sol-gel process and deposited by using spin – coating technique. The BaTiO3/Si(100) structures were studied by structural and electrical characteristics. The X-ray diffrac-tion of BaTiO3/Si(100) shows that the diffraction peaks become increasing sharp with increasing calcination tempera-tures indicating the enhance crystallinity of the films. Scanning electron microscopy of BaTiO3 thin films shows the crack free and uniform nature. The capacitance-voltage measurement of BaTiO3 thin film deposited on Si(100) an-nealed at 600℃ shows large frequency dispersion in the accumulation region. The current-voltage measurement of BaTiO3/Si shows the ideality factor was approaches to unity at 600℃.

percutaneous administration of “Orthobiologics” offers the advantage of accelerated and functional recovery of musculoskeletal disorders. Stem cell optimizes the biological healing of diseases. The regenerative capacity of mesenchymal stem cells provides a pavement for clinicians to build up an organ of interest in vitro. Mesenchymal stem cells remain the perfect cell based tissue regeneration modality for treatment of musculoskeletal disorders in a minimally invasive environment without any significant morbidity. This article outlines the applications of mesenchymal stem cell administration in various musculoskeletal disorders.

Descending branch of the lateral circumflex femoral artery (LCFA) is commonly used pedicle for ante- rolateral thigh (ALT) flap. Oblique branch of LCFA is an alternative pedicle that can be used in micro- vascular surgery. According to review of literature and to the best of our knowledge we could not find the use of oblique branch of LCFA as a pedicle of the ALT flap in regional soft tissue reconstruction. Here we presented a case of a 55-year-old man sustaining soft tissue injury and wound over the left trochanteric and gluteal region following a road traffic accident, who was treated by the use of extended ALT pedicle flap with oblique branch of LCFA as the pedicle for reconstruction of soft tissue defect in trochanteric and gluteal regions with successful outcome.

The aqueous solution of p-Sulfonatocalix[4]arene-fluorescein complex has been studied based on fluorescence and 1H NMR spectroscopic results. It has been found that the fluorescence intensity quenches regularly upon addition of p-SCX4. The proposed interaction mechanism between p-SCX4 and FL indicates that FL partially goes into the cavity of p-SCX4 with the help of strong electrostatic and π-π* interaction. The quenching constants and stability constants are determined by p-SCX4-FL systems. The proposed inclusion complex is discussed on 1H NMR results. Results are consistent with experimental data obtained from NMR spectroscopy.

The nanocrystalline of La1-xSrxCrO3 (x = 0.0, 0.1, 0.2, 0.3 & 0.4) were prepared by sol-gel method and their crystal structures & morphology were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). XRD patterns indicate that the average particle size of the nanocrystalline La0.7Sr0.3CrO3in the range of 30 - 35 nm. The gas sensing properties were studied towards reducing gases like Ammonia gas (NH3), liquefied petroleum gas (Lpg), hydrogen sulphide (H2S) and H2 gas and it is observed that undoped LaCrO3 shows response to H2S gas at relatively high operating temperature 300°C. The La1-xSrxCrO3 based sensor with x = 0.3 shows better sensitivity towards H2S gas at an operating temperature 210°C. The effect of Sr doping on sensitivity, response time and recovery time of the sensor in the presence of H2S and other reducing gases were studied and discussed.

Many applications do not fit well with the traditional best effort packet delivery policy of the Internet. These include applications such as Internet telephony and video conferencing which require voice and bulky graphical images transfer. Therefore, the policies of assigning traffic to various service classes and providing service as per the service level agreement of the user with the network provider came into existence. Multi-protocol Label Switching is the backbone of fast switching technology that helps the network service providers to implement these policies. It provides Quality of service oriented reserved paths from the source to the destination for the user’s traffic. Selection of these paths is a cumbersome task, especially when the traffic forecast is totally unknown. Furthermore, nodes and link failures in the Internet worsen the situation. This paper addresses the issue of selecting Label Switched paths (LSps) for various traffic demands in the network so that the resultant network has the characteristics like high failure resistance, low LSp demand blocking probability, low impact from the node or link failure, load balancing and low over-all resource utilization. By extensive simulations, the proposed cost function has been compared with the various cost functions mentioned in the literature and it was found to score over them in major aspects.
