In subcuticular wound closure, the use of anchorage beads or knots to maintain opposition of wound edges is a common practice, but can lead to complications. One hundred and one abdominal subcuticular wound closures (44 vertical and 57 transverse) were prospectively studied and assessment of wound swelling was made by measuring the length of exposed suture at both ends of the wound, on successi...

Bead packs of up to 150,000 mono-sized spheres with packing densities ranging from 0.58 to 0.64 have been studied by means of X-ray computed tomography. These studies represent the largest and the most accurate description of the structure of disordered packings at the grain-scale ever attempted. We investigate the geometrical structure of such packings looking for signatures of disorder. We di...

Quality of welded joint at MAG welding process depends of numbers of influences, like type and thickness of base metal, groove type, welding position etc., but the proper selection of welding parameters is also very important. Due to that, the analysis of weld bead geometry at MAG welding process with regard to weld current, voltage and weld speed (heat input) and the type and shielding gas flo...

In a previous work 1] we presented a coarse graining procedure for bonded interactions, while spherical, purely repulsive 6-12 interactions were used to account for the excluded-volume of the beads of the phantom chains. Here we extend this approach towards ellipsoidal beads whose shapes are extracted from the geometry of the underlying atomistic chains. The innuence of the bead shapes on the s...

chitosan with excellent biodegradable and biocompatible characteristics has received attention as an oral drug delivery vehicle for controlled-release formulations. in this study an enteric-coated capsule containing theophylline-chitosan beads based on 23 factorial designs was prepared as a colon drug delivery system. the theophylline-chitosan gel beads were formulated by adding the drug-contai...

abstract in this study, the extraction of carotenoids from a new strain of yeast (sporobolomyces ruberrimus h110) by different chemical and physical methods was investigated. for chemical pretreatment methods, hcl at two different concentrations (0.2 and 0.5 n) and two different temperatures (55 and 75c), and dmso solvent (also at two different temperatures, 55 and 75c) were used. sonication an...

The paper presents a design of a W-band planar accelerating structure (muffin tin) [1]. The structure is a 2 /3-mode traveling wave, constant impedance structure with an operating frequency of 91.392 GHz. The design includes a new power coupler and a cavity geometry optimized for high shunt impedance. A 7–cell cold test prototype has been fabricated by wire electro discharge machining. Measurem...

The deposition process of wire and arc additive manufacturing (WAAM) is usually planned based on a bead geometry model (BGM), which represents the relationship between geometries (e.g. width, height) required parameters. However, actual situation may deviate from one in BGM built, such as varied heat dissipation conditions, resulting morphological changes deposited beads geometrical errors form...
