iran universities of medical sciences have experienced a period of expansion in past decades. now previous concerns are alleviated, and the former quantity-based policy has given a way to a more quality-seeking attitude. in this study, we developed a planning model for expansion and stagnation of higher education in iranian universities of medical sciences based on workforce requirements of the...

in design of defense structures, concrete are often used to provide protection against incidental dynamic loadings such as the impact of a steel projectile. in the present study, a new analytical model is proposed to predict penetration depth into concrete targets by ogive nose projectile. hence, to ­ develop the model and simulate penetration of high velocity ogive-shape nose steel projectiles...

The feasibility and possible effects of palatal soft-tissue expansion in palatal repair were studied. A prospective longitudinal animal experiment was performed in 75 growing cats assigned to 5 groups. In 31 cats, a midline defect was made, and bipediced flaps were raised at the age of 8 weeks (stimulated Langenbeck operation) in order to create palatal scars. At the age of 14 weeks, custom-mad...

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

background: replacement of the lost tissue is the major concerns of the plastic surgeons. expanded area should be coherent with the surrounding tissue. tissue expansion technique is the reforming methods the skin tissue scarcities. several methods for tissue expansion are available; including usage of silicon balloon and injecting fluid into the tissue expander. materials and methods: in a clin...

In a visual cryptography scheme, a secret image is encoded into n shares, in the form of transparencies. The shares are then distributed to n participants. Qualified subsets of participants can recover the secret image by superimposing their transparencies, but non-qualified subsets of participants have no information about the secret image. Pixel expansion, which represents the number of subpi...

This paper examines the inter-relationship of three major phenomena- population growth, uncontrolled urban expansion and urban development in Ado Ekiti, Nigeria. Uncontrolled urban expansion has a resultant effect on the urban development of a city whereas uncontrolled urban development is caused by uncontrolled population increase is caused by Migration. This work encapsulates how population g...

objectives: myotonic dystrophy type i (dm1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. dm1 is associated with the expansion and instability of ctg repeat in the 3' untranslated region of the myotonic dystrophy protein kinase (dmpk) gene located on chromosome 19q13.3. the aim of this study was ...
