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...

background some sonographic positions for detection of abdominal wall hernias needed .in this paper we described the sonographic technique of abdominal wall hernia. methods from june 2013 to july 2016, three hundred seventy four patients referred in our department for evaluation of abdominal wall hernia (median age, 38 years; range 2 - 86 years). one hundred and ninety patients had abdominal he...

We investigate sample average approximation (SAA) for two-stage stochastic programs without relatively complete recourse, i.e., problems in which there are first-stage feasible solutions that not guaranteed to have a recourse action. As feasibility measure of the SAA solution, we consider "recourse likelihood", is probability solution has For $\epsilon \in (0,1)$, demonstrate likelihood below $...

background & objective: abdominal cutaneous and subcutaneous nodules are uncommon lesions which may be benign or malignant. majority of the malignant nodules are metastatic in origin and may be the initial presentation of primary malignancy, hence an early diagnosis is important. our aim was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous a...

Stimulation of the thyroid with thyroid-stimulating hormone (TSH) is a potentially useful diagnostic dysfunction, but little known about response to TSH stimulation in bottlenose dolphins (Tursiops truncatus). To better characterize dolphin stimulation, five adult participated study. Dolphins voluntarily beached onto padded mat and were given 1.5 mg intramuscular injection human recombinant TSH...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

This paper focuses on the equalization of block transmissions with zero pad (ZP). If the channel impulse response length does not exceed the ZP length, it is possible to construct zero-forcing equalizers (ZFEs). Improved performance may be achieved using a minimummean squared error (MMSE) equalizer. However, these equalizers are computationally intensive when a time-domain implementation is use...

see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...

A ll the warning signs were there: a $110-million luge track that turned out to be faster than the designer planned. There were several incidents prior to the Olympics in February 2010 that suggested that the track was not safe. A Hungarian slider was knocked unconscious the day before the fatal accident, while traveling at speeds in excess of 90 mph. Two days prior to the tragedy, a Swiss bobs...

The investigation of damage to buildings in terms of non-structural walls collapse in the past earthquakes have caused researchers to study the seismic behavior of walls more extensively. Furthermore, seismic design codes have considered using wall posts to prevent wall damage, however, not many studies were done on seismic behavior change in structures due to the addition of wall posts. Theref...
