Self Tapping Screws v/s Erich Arch Bar for Inter Maxillary Fixation: A Comparative Clinical Study in the Treatment of Mandibular Fractures.

Abstract: Introduction and Objective Numerous methods have been described for achievement of Intermaxillary fixation in the treatment of fractures of facial skeleton. Conventional methods like Erich arch bars and eyelet wires are currently most common methods for achieving intermaxillary fixation (IMF), but they have their own disadvantages. Since 1989, IMF using intraoral self tapping IMF screws has been introduced for treatment of mandibular fractures. The aim of this work was to compare the efficacy, advantages, disadvantages indications and potential complications associated with Erich archbar v/s self tapping IMF screws in the management of mandibular fractures.

Assessment of satellite image segmentation in RGB and HSV color space using image quality measures

Abstract: This paper presents a comparative study of the segmentation of satellite images in RGB and HSV color space using modified fuzzy c means clustering algorithm. The segmented images are compared with the original input images by using number of bivariate image quality parameters. These parameters measure the similarity between the input and the segmented image on the basis of comparing the corresponding pixels of the two images and present a numerical value as a result. The experiments are performed on GeoEye-1 satellite images to test the efficiency and robustness of the proposed method

Phytochemical screening and antibacterial activity of leaf and callus extracts of Centella asiatica

Abstract: The present study shows the phytochemical analysis and antibacterial activity of leaf and callus of Centella asiatica . Leaf explants of C. asiatica were cultured on MS medium supplemented with different concentration of plant growth regulators for callus initiation. The maximum percentage of callusing was achieved in medium supplemented with 6-benzylaminopurine 4.0 mg/Land 2,4-dichlorophenoxyacetic acid 2.0 mg/L. In the preliminary phytochemical screening, alkaloids, glycosides, terpenoids, steroids, flavonoids, tannins, saponins and reducing sugars were present in most of the tested extracts of leaf and in vitro grown callus of C. asiatica . Methanol, acetone, chloroform and water extracts of leaf and callus were evaluated for in vitro antibacterial activity against Bacillus cereus, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa by agar plate well diffusion method. All the extracts from leaf and callus of C. asiatica showed significant antibacterial activity against the tested organisms. However, methanol extracts of leaf and callus showed maximum inhibitory effect.
