Propeller Flaps: A Review of Indications, Technique, and Results

2014

In the last years, propeller flaps have become an appealing option for coverage of a large range of defects. Besides having a more reliable vascular pedicle than traditional flap, propeller flaps allow for great freedom in design and for wide mobilization that extend the possibility of reconstructing difficult wounds with local tissues and minimal donor-site morbidity. They also allow one-stage reconstruction of defects that usually require multiple procedures. Harvesting of a propeller flap requires accurate patient selection, preoperative planning, and dissection technique. Complication rate can be kept low, provided that potential problems are prevented, promptly recognized, and adequate…

Quantum Dual Adversary for Hidden Subgroups and Beyond

2019

An explicit quantum dual adversary for the S-isomorphism problem is constructed. As a consequence, this gives an alternative proof that the query complexity of the dihedral hidden subgroup problem is polynomial.

Shear bond strength of ceramic fused to CAD-CAM milled alloys

2018

Background This study evaluated the metal ceramic bond strength of cast Ni-Cr, cast Co-Cr, sintered Co-Cr and milled Co-Cr alloys to ceramic through two application procedures including the ceramic layering technique and ceramic pressed-on technique. Material and Methods Ceramic materials (Ø 8 mm, 1.5 mm thickness) were veneered by either the layering or pressed-on technique to cast Ni-Cr, cast Co-Cr, sintered Co-Cr and hard milled Co-Cr alloy disc (12 × 12 × 0.5 mm) (n=15). All specimens were treated with a thermal cycle process for 500 cycles at the temperature between 5 °C and 55 °C with immerse time of 30 seconds and 5 seconds for specimen transfer. The shear bond strength was determine…

Post-fatigue fracture resistance of metal core crowns: press-on metal ceramic versus a conventional veneering system

2014

Background The aim of this in vitro study was to compare the mechanical failure behavior and to analyze fracture characteristics of metal ceramic crowns with two veneering systems – press-on metal (PoM) ceramic versus a conventional veneering system – subjected to static compressive loading. Material and Methods Forty-six crowns were constructed and divided into two groups according to porcelain veneer manufacture. Group A: 23 metal copings with porcelain IPS-InLine veneering (conventional metal ceramic). Group B: 23 metal copings with IPS-InLine PoM veneering porcelain. After 120,000 fatigue cycles, the crowns were axially loaded to the moment of fracture with a universal testing machine. …

Influence of different veneering techniques and thermal tempering on flexural strength of ceramic veneered yttria partially stabilized tetragonal zir…

2019

Background Different technique for ceramic veneering and thermal tempering process are expected to be a reason for alteration in strength of ceramic veneered zirconia. This study evaluates the effect of different veneering technique and varied thermal tempering process on flexural strength of ceramic veneered zirconia. Material and Methods Ceramic veneered zirconia bars (25 mm length, 4 mm width, 0.7&1.0mm of zirconia & ceramic thickness) were prepared from zirconia block (e.max® ZirCAD), sintered at 1500°C for 4 hours, and veneered with ceramics with different techniques including CAD-fused using e.max CAD® (C), Pressed-on using e.max® Zirpress (P), and layering using e.max® ceram (L), wit…

The Life, Death and Miracles of Alan Mathison Turing

2010

The life of Alan Turing is described in many biographies. The best and most encyclopaedic of these is that of Andrew Hodges; quite pleasant is the agile volume by Gianni Rigamonti, Turing, il genio e lo scandalo (Flaccovio editore, Palermo, 1991). Both of these also make mention of his tragic end, which certainly casts a shadow on the mores English society at the time; but of course, who knows how other societies might have behaved?

Therapists’ Responses for Enhancing Change Through Dialogue: Dialogical Investigations of Change

2016

The point of view on research represented here is based on a dialogical framework. Our emphasis is on understanding the contribution of the therapists to the process of change. We conceptualize therapeutic conversation as a dialogical activity. In using the research method The Dialogical Investigation of Happenings of Change (DIHC) the focus is on how therapists participate and answer from a specific position of “responsive responsibility.” In this chapter our aim is twofold: (1) to present a method for conducting a dialogical analysis of couple sessions and (2) to track detailed sequences of events of change. To make sense of the details of this process, we use Bakhtinian concepts includin…

Developing and Testing Speaking Skills in Academic Discourse

2014

Teaching speaking is an essential aspect of developing students’ sociolinguistic competence in a foreign language at any level. English studies at the tertiary level offer a variety of courses for practicing speaking and helping students reach the C1 and C2 level in BA and MA studies, respectively. However, it is not only the level that differentiates between BA and MA studies, but also aspects of register and style. Beginning with the subjects generally called Conversation, Speaking, Oral reproduction, Argumentation skills, Debating or Public speaking (BA studies), students gradually advance to Conversation based on academic texts (MA studies). This transition requires students to raise th…

On the birational geometry of the universal Picard variety

2010

We compute the Kodaira dimension of the universal Picard variety P_{d,g} parameterizing line bundles of degree d on curves of genus g under the assumption that (d-g+1,2g-2)=1. We also give partial results for arbitrary degrees d and we investigate for which degrees the universal Picard varieties are birational.
