Objectives: We compared the transbuccal and transoral approaches in the management of mandibular angle fractures. Materials and Methods: Sixty patients with mandibular angle fractures were randomly divided into two equal groups (A, transoral approach; group B, transbuccal approach) who received fracture reduction using a single 2.5 mm 4 holed miniplate with a bar using either of the two approaches. Intraoperatively, the surgical time and the ease of surgical assess for fixation were noted. Patients were followed at 1 week, 3 months, and 6 months postoperatively and evaluated clinically for post-surgical complications like scarring, infection, postoperative occlusal discrepancy, malunion, and non-union. Radiographically, the interpretation of fracture reduction was also performed by studying the fracture gap following reduction using orthopantomogram tracing. The data was tabulated and subjected to statistical analysis. A P-value less than 0.05 was considered significant. Results: No significant difference was seen between the two groups for variables like surgical time and ease of fixation. Radiographic interpretation of fracture reduction revealed statistical significance for group B from points B to D as compared to group A. No cases of malunion/non-union were noted. A single case of hypertrophic scar formation was noted in group B at 6 months postsurgery. Infection was noted in 2 patients in group B compared to 6 patients in group A. There was significantly more occlusal discrepancy in group A compared to group B at 1 week postoperatively, but no long standing discrepancy was noted in either group at the 6 months follow-up. Conclusion: The transbuccal approach was superior to the transoral approach with regard to radiographic reduction of the fracture gap, inconspicuous external scarring, and fewer postoperative complications. We preferred the transbuccal approach due to ease of use, minimal requirement for plate bending, and facilitation of plate placement in the neutral mid-point area of the mandible.
Meshless local Petrov-Galerkin method for rotating Rayleigh beam
Vijay Panchore 국제구조공학회 2022 Structural Engineering and Mechanics, An Int'l Jou Vol.81 No.5
In this work, the free vibration problem of a rotating Rayleigh beam is solved using the meshless Petrov-Galerkin method which is a truly meshless method. The Rayleigh beam includes rotatory inertia in addition to Euler-Bernoulli beam theory. The radial basis functions, which satisfy the Kronecker delta property, are used for the interpolation. The essential boundary conditions can be easily applied with radial basis functions. The results are obtained using six nodes within a subdomain. The results accurately match with the published literature. Also, the results with Euler-Bernoulli are obtained to compare the change in higher natural frequencies with change in the slenderness ratio (√ 0 2 / 0). The mass and stiffness matrices are derived where we get two stiffness matrices for the node and boundary respectively. The non-dimensional form is discussed as well.

In the present work, a simple approach for colorimetric determination of allopurinol and its majormetabolite oxypurinol is presented using gold nanoparticles as a probe. Gold nanoparticles weresynthesized using the citrate reduction method and then functionalized using melamine (mel-AuNPs). The nanoparticles were characterized using UV–vis spectrophotometry, dynamic light scattering andtransmission electron microscopy. The bare AuNPs capped with citrate anions (cit-AuNPs) gave a linearresponse towards allopurinol and oxypurinol within the range 0.20–40.0 mM and 0.25–25.0 mMrespectively; however the melamine functionality on the AuNPs exhibited specific response foroxypurinol from 0.10 to 15.0 mM. This enabled development of a simple approach for the quantitation ofthe metabolite using mel-AuNPs, while the quantitation of allopurinol was carried out using theregression parameters of cit-AuNPs and the calculated amount of metabolite. For method optimizationparameters such as the pH, incubation time and effect of ionic strength of the medium which can causeaggregation of nanoparticles were studied. The methodology was found to yield reliable results asevident from the validation results. The application of the method is demonstrated by analyzingallopurinol from tablet formulations and the drug and its metabolite from spiked plasma samples.
On Baskakov-Szasz Type Operators
Vijay Gupta,Prerna Maheshwari 경북대학교 자연과학대학 수학과 2003 Kyungpook mathematical journal Vol.43 No.3
Baskakov-Szasz type operators were recently introduced by Gupta and Srivastava in 1993. They obtained direct theorems in simultaneous approximation for the linear combinations of these new sequence of operators. In the present paper, we extend the results of Gupta and Srivastava and obtain a converse result for the linear combinations of these Baskakov-Szasz type operators.
