مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولOntogenetic patterns of limb loading, in vivo bone strains and growth in the goat radius.
As tetrapods increase in size and weight through ontogeny, the limb skeleton must grow to accommodate the increases in body weight and the resulting locomotor forces placed upon the limbs. No study to date, however, has examined how morphological changes in the limb skeleton during growth reflect ontogenetic patterns of limb loading and the resulting stresses and strains produced in the limbs. ...
متن کاملEnlargement of growth plate chondrocytes modulated by sustained mechanical loading.
BACKGROUND Mechanical compression and distraction forces are known to modulate growth in vertebral growth plates, and they have been implicated in the progression of scoliosis. This study was performed to test the hypothesis that growth differences produced by sustained compression or distraction loading of vertebrae are associated with alterations in the amount of increase in the height of gro...
متن کاملWeight loading young chicks inhibits bone elongation and promotes growth plate ossification and vascularization.
The mechanical stimuli resulting from weight loading play an important role in mature bone remodeling. However, the effect of weight loading on the developmental process in young bones is less well understood. In this work, chicks were loaded with bags weighing 10% of their body weight during their rapid growth phase. The increased load reduced the length and diameter of the long bones. The ave...
متن کاملGrowth plate chondrocyte enlargement modulated by mechanical loading.
Mechanical compression and distraction forces are known to modulate growth in vertebral growth plates, and are implicated in the progression of scoliosis. The amount of cellular enlargement is thought to be a key variable correlating with differing growth at different anatomical sites. This work tested the hypothesis that growth differences produced by mechanical loading are associated with alt...
