با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...

A New Technique based on Strain Energy for Correction of Stress-strain Curve

Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...

Validation of a Biomechanical Model of the Lumbar Spine

INTRODUCTION Hansen et al [1] and de Zee et al [2] reported on a new and very detailed model of the human lumbar spine. In its current version the model comprises a total of 194 spinal muscle fascicles spanning the pelvis, sacrum, five lumbar vertebrae and the joint between the lumbar and thoracic parts. In addition, the abdominal muscles are included in the model and may contribute to extensio...

Lumbar spine densitometry.

failure of antigen production is more likely to be due to genetic change associated with incomplete penetrance than to genetic loss. An alternative or additional possibility cannot, however, be excluded-that exuberant cell division causes dilution of a particulate cytoplasmic factor responsible for the formation of the antigen. Loss of organ-specific antigens could influence tumour metastasis b...
