Comprehensive understanding of the biomechanical performance of the lamina cribrosa (LC) and the optic nerve head is central to understanding the role of elevated intraocular pressures (IOP) in chronic open angle glaucoma. In this paper, six closed-from mathematical models based on different idealizations of the LC are developed and compared. This approach is used to create further understandin...

• Dynamic model of a single-link system with pretensioned cables is developed. Effect cable pretension investigated through von Kármán nonlinearity. Analytical formulation buckling load derived from dynamical modelling. Results ANSYS analysis are compared calculated results. Experimental verification link performed. This paper utilizes the extended Hamilton's principle to develop dynamic flexib...

Number of Disciplines and Theories changed their status from status of Natural Science discipline to Mathematics. The Theory of Probability is the classical example of that kind. The main privilege of the new Math status is the conception of Math truth, which distinguishes Math from other theories. Some disciplines used in Applications pretended to be Math not really being it. It is entirely tr...

The tapered implant-abutment interface is becoming more popular due to the mechanical reliability of retention it provides. Consequently, understanding the mechanical properties of the tapered interface with or without a screw at the bottom has been the subject of a considerable amount of studies involving experiments and finite element (FE) analysis. This paper focuses on the tapered implant-a...

The aim of this paper is to explore the key influences of the wall stiffness on the stability and self-excited oscillations of the flow in collapsible channels. To identify mechanism of the oscillations found in the full numerical solutions, a linear eigenvalue problem of the Orr-Sommerfield equations modified by the beam is solved. Excellent agreement is found between the onset of small amplit...

Tibiofibular syndesmotic injuries may cause degenerative changes, reduction in ankle function and compromising stability. Different fixation techniques try to restore its functionality. Screw-fixation is the gold-standard. Recently, suture-button has aroused attention because it allows for physiologic micromotion while maintaining an accurate reduction. The aim of this study compare biomechanic...

An encyclopaedia is described as ‘a work containing exhaustive information on some one branch of knowledge’ (Oxford English Dictionary). This is truly a high pretension of Steven Yentis and his co-editors for their new edition of Anaesthesia and Intensive Care Medicine A–Z: An Encyclopaedia of Principles and Practice. According to the Preface, the authors have tried ‘to produce a readily access...

Tensegrity structures are nice-looking and statically strong architectural complexes composed of a set of disjoint struts tied together by cables and nothing more. These structures are known for their aesthetic and structural qualities, which are explored in architecture and art. Their perceived lightness is their distinct visual feature: the heavy elements (the struts) are well disjoint, yet t...
