A cleft sternum is a rare congenital anomaly often diagnosed as asymptomatic at birth. Clinical outcome may be unfavorable when an associated anomaly, particularly an intracardiac anomaly coexists with the defect. Primary repair should be employed in the neonatal period because the flexibility of the chest wall is maximal and compression of underlying structures is minimal. However, patients wi...

Introduced as a system in earthquake engineering in 2004 [6], rocking walls are a fairly new system in earthquake engineering. Their performance has been proven, both in research as in practice. However, a few uncertainties about their behavior still remain. One of these uncertainties is the effect of radiation damping on the motion of the system. Existing estimations for the radiation damping ...

We consider an ideal gas of infinitely rigid rods near a perfectly repulsive wall, and show that the interfacial tension of a surface with rods on one side is lower when the surface bends towards the rods. Surprisingly we find that rods on both sides of surfaces also lower the energy when the surface bends. We compute the partition functions of rods confined to spherical and cylindrical open sh...

Efficient and precise comparison of parser results across frameworks will require a negotiated agreement on a target representation which embodies a good balance of three competing dimensions: consistency, clarity, and flexibility. The various annotations provided in the COLING-08 shared task for the ten ’required’ Wall Street Journal sentences can serve as a useful basis for these negotations....

Congenital sternal cleft is a rare chest wall malformation. Because of the flexibility of the chest in infants, surgical repair should be performed by primary closure in the neonatal period. In adolescents and adults, different techniques have been suggested to overcome the lack of sternal bone tissue. We describe a very rare case of an 18-year-old woman with a complete bifid sternum associated...

background and objective: mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. materials and methods: the clinical and laboratory features of 65 patients who had open biopsies in ali-asghar hospital over 11 years were reviewed. results: seventy-...

osteosarcoma (osteogenic sarcoma: os) is the most common primary malignant bone tumor of long bones, whereas primary osteosarcoma of chest wall, especially in sternum, is extremely rare. we report a 57-year-old man with an immobile slow growing mass located in the middle of the sternum. the patient had no significant pain or tenderness and the past medical history was not remarkable. ct-scan sh...

Residential consumers are moving to the center of electricity systems and their flexibility is seen as a key resource integrate renewable energy sources support grid. However, residential capacities not homogeneous, they depend on household appliances, comfort patterns, occupancy, climate conditions. Here, we calculate technical 45 consumer types in mainland Spain, organised according income re...

recently, women’s participation has increased in the workplaces. therefore it is a challenge for contemporary managers to help employees to balance their work and family responsibilities. this paper aims to identify factors affecting the work-family balance. sample included 261 women employed at a number of universities in tehran. data is collected from the questionnaire. correlation and multip...

The largest unsteady 3-D computational fluid dynamics (CFD) results produced today exceed 100 gigabytes. Visualizing these large data sets stresses computational resources, requiring users and visualization systems to make trade-offs between time, space, and flexibility. Current CFD visualization systems make trade-offs which severely limit visualization of the largest unsteady 3-D CFD results....
