A track graph is a graph with its vertex set partitioned into horizontal levels. It is track planar if there are permutations of the vertices on each level such that all edges can be drawn as weak monotone curves without crossings. The novelty and generalisation over level planar graphs is that horizontal edges connecting consecutive vertices on the same level are allowed. We show that track pl...
In practice, clearances in the joints are inevitable due to tolerances, and defects arising from design and manufacturing. In the presence of clearance at a joint, a mechanism gains some additional, uncontrollable degrees of freedom which are the source of error. Moreover, joints undergo wear and backlashes and so cannot be used in precision mechanisms. In this study, the dynamic behaviour of ...
this study aimed to compare the efficacy of mta and cem cement in class ii furcation defects in human mandibular molars.forty furcation defects were treated in 16 patients with chronic periodontitis. the clinical parameters of probing depth (pd), vertical and horizontal clinical attachment levels (vcal and hcal), open vertical and horizontal furcation depths (ovfd and ohfd), and gingival margin...
Correspondence to: Manoj Humagain Department of Periodontics Manipal College of Dental Sciences Mangalore, Karnataka,India Email: [email protected] Phone: +919886446797 Abstract Bioactive glass particulate has been applied to dentistry in the treatment of bone defects, ridge preservation and periodontal bone defects including the furcation defects. The aim of this study was to compare the c...
A shape visibility representation displays a graph so that each vertex is represented by an orthogonal polygon of a particular shape and for each edge there is a horizontal or vertical line of sight between the polygons assigned to its endvertices. Special shapes are rectangles, L, T, E and H-shapes, and caterpillars. A flat rectangle is a horizontal bar of height > 0. A graph is 1-planar if th...
A bar 1-visibility drawing of a graph G is a drawing of G where each vertex is drawn as a horizontal line segment called a bar, each edge is drawn as a vertical line segment where the vertical line segment representing an edge must connect the horizontal line segments representing the end vertices and a vertical line segment corresponding to an edge intersects at most one bar which is not an en...
background and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...
We identified two novel mouse mutants with abnormal head-shaking behavior and neural tube defects during the course of independent ENU mutagenesis experiments. The heterozygous and homozygous mutants exhibit defects in the orientation of sensory hair cells in the organ of Corti, indicating a defect in planar cell polarity. The homozygous mutants exhibit severe neural tube defects as a result of...
