large capacity cylindrical tanks are used to store a variety of liquids. their satisfactoryperformance during earthquake is crucial for modern facilities. in present paper, the behavior of cylindricalconcrete tanks under harmonic excitation is studied using the finite element method. liquid sloshing, liquidviscosity and wall flexibility are considered and additionally excitation frequency, liqu...

AIMS Left ventricular ejection fraction (EF) is a suboptimal measure of ventricular function. Recent mathematical modelling of left ventricular contraction has shown that the EF is determined by both myocardial shortening (strain) and by end-diastolic wall thickness. Increasing end-diastolic wall thickness resulted in augmented radial wall thickening. This may result in a significant 'overestim...

Wall thickness is an important parameter for casting design. Thin wall sections cause breakage of parts during manufacturing or during usage of the part. Thick wall sections cause problems in castings and increase weight, needs more material thus increasing the cost. Optimal wall thickness is also important for adequate and sufficient strength of parts. The current process of wall thickness mea...

INTRODUCTION Tracheal wall thickness is a substantial indicator in various pathological changes. The present study was performed to compile normative data and formulae for the tracheal wall thickness and volume at varying gestational age. MATERIAL AND METHODS Using anatomical dissection, digital image analysis and statistics a range of the wall thickness, proximal internal-to-external cross-s...

Myocardial thickness, left ventricular functions, and right heart overloading were investigated in 80 patients with systemic sclerosis by echocardiography. Based on the left ventricular wall thickness, three groups were formed. Fifteen patients with asymmetrical left ventricular wall hypertrophy (Group 1) showed shorter mean disease duration with marked diastolic and mild systolic left ventricu...

BACKGROUND Left ventricular hypertrophy is a heterogeneous disorder with distinct morphologies. Changes in wall thickness, left ventricular chamber diameter, and mass alter systolic wall stress of the left ventricle and may influence ischemic threshold. Thus, the goal of this study was to investigate the effect of the different patterns of left ventricular hypertrophy on the accuracy of dobutam...

Introduction: Knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. The purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   Materials and Methods: Thirty five Cone-Beam Computed Tomography (CBCT)...

BACKGROUND Colonic strictures represent an advanced stage of fibrosing colonopathy in patients with cystic fibrosis. AIMS To clarify whether ultrasonography can identify patients with an early stage of fibrosing colonopathy and to determine clinical factors that influence bowel wall thickening. PATIENTS Ninety patients with cystic fibrosis, median age 10 years, and 46 healthy controls, medi...

OBJECTIVE To examine the impact of age, sex and exercise on wall thickness and remodelling in the popliteal and brachial arteries. METHODS We compared wall thickness, lumen diameter and wall:lumen ratios in the brachial and popliteal arteries of 15 young (Y, 25.4+/-0.8 yr; 7M 8W) and 16 older sedentary (OS, 58.8+/-1.1 yr; 8M 8W) subjects, with 12 of the OS group also studied following 12 and ...

S egmental variation in left ventricular (LV) wall thickness is important in characterizing hypertrophic cardiomyopathy, post-infarction remodeling, and myocardial noncompaction. In each of these disorders, cardiac magnetic resonance (CMR) has greatly extended our understanding due to its ability to comprehensively assess LV structure, function, and myocardial composition over the entire LV cha...
