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...

Pawpaw fruit were harvested at the advent of the ripening process and were ripened at room temperature. Based on fruit fi rmness and respiration and ethylene production rates at harvest and during ripening, fruit were classifi ed into one of four categories: preripening (no to very slight loss of fi rmness; preclimacteric), early ripening (some softening; increasing rates of ethylene and CO2 pr...

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...

Plant cuticles on outer fruit and leaf surfaces are natural macromolecular composites of waxes and polyesters that ensure mechanical integrity and mitigate environmental challenges. They also provide renewable raw materials for cosmetics, packaging, and coatings. To delineate the structural framework and flexibility underlying the versatile functions of cutin biopolymers associated with polysac...

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...

Conservation of respired CO(2) by an efficient recycling mechanism in fruit could provide a significant source of C for yield productivity. However, the extent to which such a mechanism operates in cotton (Gossypium hirsutum L.) is unknown. Therefore, a combination of CO(2) exchange, stable C isotope, and chlorophyll (Chl) fluorescence techniques were used to examine the recycling of respired C...

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)...
