natural hazards such as earthquakes have threatened the life of human beings during the history.as a consequence, the vibration mitigation of structures has caught great importance. activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

Otoliths are considered as very useful structures of fishes for various studies. This investigation aimed to compare the morphometric parameters between the right and left otoliths of male and female specimens of four species of the fishes belonging to the family Carangidae from the northern Persian Gulf. The morphometric parameters such as weight, length, width, area and perimeter of sagittal ...

Otoliths are considered as very useful structures of fishes for various studies. This investigation was aimed to compare morphometric parameters between right and left otoliths of males and females fishes amongst four species belong to the family Carangidae from the northern Persian Gulf. The morphometric parameters such as weight, length, width, area and perimeter were measured and then compar...

the sofeh mountain in the south of isfahan (iran) has a development of shafts (vertical cave). simorgh cave with a depth of 42 m and a length of 52 m has developed along significant fault structures. structural analysis indicates relationships of orientation between the faults and fractures and shafts and chambers geometries. considering the main ne-sw trend of tectonic structures in the area, ...

ultrasonography is a relatively easy, safe and non-invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations. as there has been no collated study undertaken on the normal measurements of ocular structures in caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye ...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

The celiac ganglia and the visceral plexus are complexes structures, disposed in the proximity of the main collateral branches of the aorta. Pre visceral ganglia are sympathetic ganglia chains between the lateral vertebral sympathetic chain and viscera. Our study is made in the anatomy lab on 30 adult human bodies, one of new born and 10 human fetal specimens with crown-rump lengths from 9 to 2...

Light-induced forces can bind dielectric spheres into extended structures through two mechanisms, each with its own length scale which can be adjusted by the configuration of the external light source. By manipulating the commensurability of the two length scales, these two mechanisms can cooperate to bind a large number of spheres. When the two length scales become incommensurate for some part...
