This work presents a new model for the shakedown analysis of Kirchhoff plates under uncertain conditions plastic moment by direct method. The stochastic models are normal or lognormal distribution. New formulations derived to compute lower bound and upper loads dual algorithm is established calculate load factors simultaneously chosen structural reliability level. An example examined illustrate shows robust results analysis.
Background: Numerous single- and double-row repair techniques with simple modified stitches have been described for subscapularis tendon tears. Purpose/Hypothesis: This study aimed to uniformly evaluate the influence of 4 different on biomechanical performance fixation full-thickness It was hypothesized that (1) 2 single-row would require more cycles result in 3- 5-mm gap formation a higher load failure after cyclic loading than technique (2) also significantly compared technique. Study...
Background/Aims: Common systems for the quantification of cellular contraction rely on animal-based models, complex experimental setups or indirect approaches. The herein presented CellDrum technology testing mechanical tension monolayers and thin tissue constructs has potential to scale-up towards medium-throughput analyses. Using hiPS-Cardiac Myocytes (hiPS-CMs) it represents a new perspective drug brings us closer personalized medication. Methods: In present study, self-beating hiPS-CMs...
After menopause, decreased levels of estrogen and progesterone remodel the collagen soft tissues thereby reducing their stiffness. Stress urinary incontinence is associated with involuntary urine leakage due to pathological movement pelvic organs resulting from lax suspension system, fasciae, ligaments. This study compares changes in orientation position female weakened ligaments, combined laxity. A mixture theory weighted by respective volume fraction elastin-collagen fibre compound (5%),...
To elaborate the impact of new haemostatic agents we developed an instrument for pressure-controlled induction blunt liver injuries in a porcine animal model.A dilutional coagulopathy 80% blood volume was induced 9 anaesthetized pigs. Animals were randomly assigned to be injured with force 112 Newton (N) (n = 1), 224 +/- 19 N 4) or 355 35 4). The injury measured by loss, survival time and coagulation parameters. Liver histology obtained evaluate degree injury.The profound haemodilution...
Summary Dental trauma is a common complication of tracheal intubation. As existing evidence insufficient to validly assess the impact different laryngoscopy techniques on incidence dental trauma, force exerted onto structures during intubation was investigated. An manikin equipped with hidden sensors in all maxillary incisors. measured while 104 anaesthetists performed series intubations using direct Macintosh blade, and videolaryngoscopy C‐ MAC ® , or hyperangulated GlideScope KingVision...
Abstract The paper describes the application of primal‐dual theory limit and shakedown analysis in safety assessment design pressure components according to new European approach by analysis. Two methods, static kinematic one, their combination, method, are discussed. A numerical example is presented show robustness method compared with two other methods recently used projects on design.

Surgical reconstruction of the interosseous membrane may restore longitudinal forearm stability in Essex-Lopresti lesions. This study aimed to compare intact with a single-bundle and double-bundle central band using digital image correlation three-dimensional camera system. Single cyclic axial loading eight fresh-frozen specimens was carried out state, after creation an lesion, TightRope® (Arthrex GmbH, Munich, Germany) construct. Instability significantly increased lesion. The similar both...
