background and aims. the aim of this study was to assess the opening torque of grooved and non-grooved screws made of shape memory alloys (sma) for fixation of mandibular fractures. materials and methods. in this in vitro study the opening torques of ten sma screws with grooves and ten sma screws without grooves were compared in 20 holes (10 holes for grooved screws and 10 holes for non-grooved...

An efficient and simple method for the preparation of Si-Imidazole-HSO4 functionalized magnetic Fe3O4 nanoparticles (Si-Im-HSO4 MNPs) and used as an efficient and reusable magnetic catalysts for the regioselective ring opening of epoxides under green conditions in water. This catalyst was used for the ring opening of epoxide corresponding to the thiocyanohydrins and azidohydrines. Compared to t...

Algorithms are presented which allow to perform morphological transformations on unorganised sets of points represented by their Delaunay triangulation. The results show that these algorithms could behaves as morphological operators such as erosion, dilatation, opening do. As a matter of fact, they actually act as “shape filter”. These algorithms are applied to the problem of scene reconstructi...

let $omega_x$ be a bounded, circular and strictly convex domain of a banach space $x$ and $mathcal{h}(omega_x)$ denote the space of all holomorphic functions defined on $omega_x$. the growth space $mathcal{a}^omega(omega_x)$ is the space of all $finmathcal{h}(omega_x)$ for which $$|f(x)|leqslant c omega(r_{omega_x}(x)),quad xin omega_x,$$ for some constant $c>0$, whenever $r_{omega_x}$ is the m...

This paper provides a regression model in which both covariates and responses are angular variables. The regression curve is expressed as a form of the Möbius circle transformation. The angular error is assumed to follow a wrapped Cauchy or, equivalently, circular Cauchy distribution. A bivariate circular distribution is proposed to model our circular regression. Some properties of the regressi...

circular- crested weirs are employed for flow measurement among their other wide applications in hydraulic engineering. they can also be used to control water level in farm ponds and reservoirs. advantages of the circular crested weirs as compared to other weirs include the stable overflow pattern, the simplicity of design and their associated lower costs. in this study, the curvilinear flow pa...

BACKGROUND Although the published data have clearly related the size of the gastrojejunostomy anastomosis to the subsequent likelihood of a stricture, a correlation between the anastomosis size and postoperative weight loss has not previously been described. METHODS A retrospective comparison was made of 124 anastomoses accomplished with the 21-mm circular stapler followed by 100 anastomoses ...

The essential Bacillus subtilis DnaD and DnaB proteins have been implicated in the initiation of DNA replication. Recently, DNA remodeling activities associated with both proteins were discovered that could provide a link between global or local nucleoid remodeling and initiation of replication. DnaD forms scaffolds and opens up supercoiled plasmids without nicking to form open circular complex...

The morphology, infraciliature, and silverline system of a new marine scuticociliate, Dexiotrichides pangi n. sp. were investigated. The new species is characterized by: size about 45-65 x 20-25 microm in vivo with kidney-like body shape and obliquely truncated semicircle-shaped apical plate; cytostome at bottom of conspicuously depressed oral cavity, which is located at the cell equatorial lev...
