The purposes of this study were to evaluate the ability of a group of third-year dental students without any endodontic clinical experience to use the ProTaper Instruments (Dentsply Maillefer) to decrease the amount of straightening of curved canals on human molar teeth and to determine the incidence of instrument fractures and instrumentation time. Thirty-one undergraduate dental students in T...
Changes to software systems often entail a loss of quality, especially if they have to be accomplished under pressure of time. Long-term software projects must counter this phenomenon one way or the other to preserve long-term maintainability. This paper presents the results of a case study trying to improve an extensive low-quality code base by object-oriented and tool-supported refactoring. T...
We study the barycentric straightening of simplices in higher rank irreducible symmetric spaces of non-compact type. We show that, for an n-dimensional symmetric space of rank r ≥ 2 (excluding S L(3,R)/S O(3) and S L(4,R)/S O(4)), the p-Jacobian has uniformly bounded norm, provided p ≥ n − r + 2. As a consequence, for the corresponding non-compact, connected, semisimple real Lie group G, in deg...
Flame straightening is a common procedure used for repair work in steel components. It is based on heating a local region of the part by means of a flame torch. Due to the obstruction of the heat expansion, upsetting occurs in the work material. During cooling of the squashed zone shrinkage occurs and that is associated with tension forces which lead to the desired deformation. This process is ...
Molecular dynamics simulations of smooth and striated muscle myosin regulatory light chain (RLC) N-terminal extension (NTE) showed that diphosphorylation induces a disorder-to-order transition. Our goal here was to further explore the effects of mono- and diphosphorylation on the straightening and rigidification of the tarantula myosin RLC NTE. For that we used MD simulations followed by persis...
Aortic dissection (AD) is a life-threatening cardiovascular disease with high mortality rate. The accurate and generalized 3-D reconstruction of AD from CT-angiography can effectively assist clinical procedures surgery plans, however, clinically unavaliable due to the lacking efficient tools. In this study, we presented novel multi-stage segmentation framework for type B extract true lumen (TL)...
The European Resuscitation Council has produced these first aid guidelines, which are based on the 2020 International Consensus Cardiopulmonary Science with Treatment Recommendations. topics include management of emergency medicine and trauma. For medical emergencies following content is covered: recovery position, optimal positioning for shock, bronchodilator administration asthma, recognition...
