This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...
background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...
Simultaneous effects of mooring characteristics and waves heading on mooring forces of a multi-rows floating pier which is composed of pontoons have been investigated in this paper. The investigated variable parameters include the moorings array, number of mooring lines and their pretensions. A floating structure consisting of 12 pontoons connected together with rigid connectors and is located ...
In the present paper optimum height of skirt of Skirt Pontoon Floating Breakwater are reported by physical model. 54 tests on 3 types (skirt heights : 8,16 and 24 cm) of skirt pontoon floating breakwater is conducted in the wave flume of Soil Conservative and Watershed Research Center. Hydrodynamical and geometrical parameters were analysised. In this research optimum height of skirt to water d...
abstract the new drug delivery systems have been developed, which can remain in the stomach for prolonged period of time. the effervescent floating tablet is one of these systems. iron deficiency anaemia is a common disease in the world. ferrous sulphate is the most common ferrous preparation used to treat and prevent...
Background and aims: Process industries are known to be hazardous industries. Chemical Industrial process involves several processes such as drilling and production, storage, transportation, and refining. These activities are different in nature. Also, they are different in job Risks. One of the main and dangerous sections of the process is oil reservoir. Therefore, this study aimed to identify...
Using finite element method, free vibration of very large circular floating structures is investigated based on the first order shear deformation theory. The very large floating structure is modeled as an elastic plate with free edges. The free vibration of a circular plate in contact with air (the dry plate) is investigated and the natural frequencies and mode shapes of the plate are determine...
in this paper, we present a case of bacterial endocarditis of the prosthetic pulmonary conduit found in a 26-year-old man. an echocardiography study around the pulmonary valve showed the presence of a floating mass attached to the wall of the conduit. this formation was thought to be a floating calcific leaflet of the conduit or a developed vegetation of the conduit. due to the uncertainty of t...
purpose: to report a case of free floating pyogenic granuloma within the lacrimal sac. case report: a 13 month old infant with unresolving dacryocystitis and history of two times failed probing and once failed turbinate fracture was scheduled for dacryocystorhinostomy (dcr). a free floating red mass was removed from the sac. histopathologic examination confirmed a diagnosis of pyogenic granulom...
Predicting currency fluctuations and crises is an important step in the foreign exchange policy of countries. Given that the purpose of early warning systems or patterns is to anticipate crises, their use is essential to prevent economic crises, including currency crises. Therefore, the purpose of this study is to model and rank the early warning factors of currency crisis by Bayesian averaging...
