Several methods have been used in wound closure after coronary artery bypass grafting (CABG). In this study, the safety and efficacy of one of these methods, Steri-Strip S is compared with the traditional intracuticular suture method. Eighty-one patients undergoing CABG were prospectively randomized into two groups according to the method of skin closure: Steri-Strip S group and traditional sut...

Discrete tomography deals with image reconstruction of an object with finitely many gray levels (such as two). Different approaches are used to model the raw detector reading. The most popular models are line projection with a lattice of points and strip projection with a lattice of pixels/cells. The line-based projection model fits some applications but involves a major approximation since the...

In a hot strip mill, the strip is cooled by spraying water from top and bottom on the RunOut Table (ROT), before the strip is coiled. The desired mechanical properties and metallurgical structure of the strip is achieved by controIling the cooling rate and temperature of the strip on the ROT. This paper describea a novel real time simulator for ROTs. The simulator has been implemented in parall...

Levitov‡ †Department of Physics and Astronomy, University of Sheffield, Sheffield S3 7RH, UK ‡Center for Materials Science & Engineering, Physics Department, MIT, Cambridge, MA-02139 Abstract The incompressible Quantum Hall strip is sensitive to charging of localized states in the cyclotron gap. We study the effect of localized states by a density functional approach an...

Performance of a helical antenna designed for 2.4-GHz WLAN is experimentally investigated in terms of impedance matching. A section of the helical wire near the antenna feed point is replaced by a simple triangular copper strip. By deploying such technique, impedance matching can be achieved. Overall return loss is below −14 dB across entire WLAN frequency range. Moreover, overall return loss d...

this paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. an analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. wusatowskis model which is developed to give an account of spreading is specified and a similar model to ...

in this paper free vibration analysis of two rectangular isotropic plates, which are connected to each other by two translational and rotational springs along the edges, are investigated. the equation of motion and associated boundary and continuity conditions are derived using the extended hamilton principle. to solve the eigenvalue problem, the ritz method is utilized. numerical investigation...

to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...
