Large-strains beam formulation from hyperelasticity

We present a formulation for large-strains analyses of beams made of hyperelastic materials. Building upon Reissner beam theory, we establish a connection between beam internal forces and the stress components of continuum hyperelasticity. The transition from the three-dimensional continuum to the one-dimensional beam approximation is achieved by constraining the volumetric part of the strain energy function. As a result, closed-form expressions for the beam internal forces as functions of th...

Validating a Web-based Diabetes Education Program in continuing nursing education: knowledge and competency change and user perceptions on usability and quality

Background: Nurses as the members of health care professionals need to improve their knowledge and competencies particularly in diabetes mellitus through continuing nursing education programs. E-learning is an indirect method of training that can meet nurses' educational needs. This study is aimed at validating a web-based diabetes education program through measurement of nurses' knowledge and clinical competency in diabetes and nurses' perception about its usability and quality. Methods: Thi...

Infection rates following custom-made cranioplasty using heterologous materials: insights from a systematic review on 3260 patients with a focus on follow-up length

Introduction: Custom-made cranioplasty can be performed using various heterologous materials, each associated with a distinct complication profile. This systematic review focuses on infections, the most common complication following cranioplasty. Materials and methods: A systematic review of the available literature was conducted to identify infection and explantation rates associated with materials used in custom-made heterologous cranioplasty. A comprehensive search of PubMed/MEDLINE, Scopu...
