Integrated FEM/BEM approach to the dynamic and acoustic analysis of plate structures

An integrated finite element/boundary element method approach to the prediction of the interior acoustic radiation of open ended box structures is presented. Dynamic response of the structure is predicted in terms of the nodal displacements under sinusoidal point force excitation using the finite element method. Theoretical results obtained in terms of frequency response functions are verified using the results from tests performed on a box structure. The interior acoustic field is then examined by the boundary element method using the boundary conditions obtained from the finite element analysis. Sound pressure levels produced inside the structure are calculated and the results are compared with the experimental measurements. Copyright (C) 1996 Elsevier Science Lt

Anatomic variations of the coracoacromial ligament in neonatal cadavers: A neonatal cadaver study

One of the most common causes of pain and disability in the upper limb is inflammation of the rotator cuff tendons. When no significant bony abnormality exists in the surrounding structures, the coracoacromial ligament has been implicated as a possible cause of impingement on the cuff tendons and various morphological variants of the ligament have so far been claimed to be either the cause or the result of impingement. In this study, 110 shoulders from 60 neonatal cadavers that were preserved in a preparation of formaldehyde were dissected. Anatomic variations of coracoacromial ligaments were investigated with metric and histologic analysis. Three main ligament types were identified: quadrangular, broad band and U-shaped. The multiple banded ligament was not found. Histologic analysis showed that in U-shaped ligaments a thin tissue existed in the central part of the ligament close to the coracoid. Comparing our data with the adult measurements of a previous study we suggest that the primordial ligament is broad shaped, but assumes a quadrangular shape due to the different growth rates of the coracoid and acromial ends. We also suggest that broad and U-shaped ligaments account for the primordial and quadrangular and Y-shaped ligaments account for the adult types of the single or double banded anatomic variants respectively. Our results show that various types of the coracoacromial ligament are present at the neonatal period and that the final shape of the ligament should be defined by developmental factors, rather than degenerative changes.

Evaluation of the histopathological diagnosis of patients preoperatively diagnosed with atypical endometrial hyperplasia after hysterectomy

WOS: 000309738600003PubMed ID: 23185787Objective: To evaluate the patients diagnosed with atypical endometrial hyperplasia preoperatively, and compare preoperative and postoperative results. Materials and method: We investigated the files of 58 patients diagnosed with atypical endometrial hyperplasia who were treated surgically after clinical evaluation. We compared sociodemographic diagnosis, preoperative and postoperative diagnosis. Results: Mean-age of patients was 51.7. Obesity, diabetes mellitus, hypertension and infertility were seen, respectively, in eight cases (13.7%), 12 cases (20.6%), 19 cases (32.7%) and four cases (6.8%). While endometrial cancer was not found postoperatively in patients preoperatively diagnosed with simple atypical endometrial hyperplasia, we determined well differentiated endometrial adenocarcinoma in 44.7% of the patients. Conclusion: In the literature the probability of developing well differentiated endometrial cancer from complex atypical endometrial hyperplasia is 40-50%. All patients diagnosed with complex atypical hyperplasia should be evaluated preoperatively for well differentiated adenocarcinoma and undergo an appropriate surgical technique and staging
