BACKGROUND An appropriate and well-timed surgery has great impact on a patient's treatment and can prevent further damage to partially injured structures which if untreated will be lost leading to severe disability. In the present study we report our experience with early coverage of electrically injured upper extremity vital structures with encouraging results. OBJECTIVES The aim of this stu...

elevated tanks are very important structures and consist of various types. water supply is vital to control fires during earthquakes. also they are utilized to store different products, like petroleum supplies in cities and industrial zones. damage to these structures during strong ground motions may lead to fire or other hazardous events. elevated tanks should stay functional after and before ...

elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. these structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. damage to these structures during strong ground motions may lead to fire or other ...

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...

There are multiple approaches to sensitivity analysis used to identify the age(or stage-) specific rate of reproduction or survival that most affects population growth—all of which involve evaluating effects on k, the dominant eigenvalue of the Leslie matrix. Management recommendations generated by these approaches can be difficult to determine, in part because results are valid only for popula...

Admission of a patient to an intensive care unit for management of direct consequences of a hematologic or oncologic disease is occasionally necessary. Such problems included exchange transfusion, sepsis, compression of vital structures by malignant tumor, metabolic derangements, leukostasis, post-operative care, major sickling episodes in vital organs, and disseminated coagulopathy. More often...

Before the advent of ultrasound, percutaneous pericardiocentesis was associated with relatively high mortality and complication rates (6% and 20-50%, respectively) [1-3]. Ultrasound (US)-guided pericardiocentesis has dramatically decreased the incidence of complications by direct visualization of the heart and other adjacent vital structures. US helps localize the size and location of the peric...
