Thymoma Associated with Hypergammaglobulinemia: A Case Report
Thymoma is a term that should be restricted to neoplasms of thymic epithelial cells, irrespective of the presence or the number of lymphocytes. The usual location of thymoma is the antrosuperior mediastinum; however, this tumor can also occur in other mediastinal compartments, in the neck, within the thyroid gland, in the pericardial cavity, the pulmonary hilum, within the lung parenchyma, o...
متن کاملResolution composite shell with a layer of piezoelectric vibration analysis
In this paper, the vibration of composite cylindrical shell with piezoelectric layers in the interior and exterior surfaces is investigated. The composite shell without piezoelectric layers can be studied and compared the results with the results of other researchers, the cylindrical shell laminated with layers of piezoelectric vibration checked. The result is a three-dimensional elasticity equ...
متن کاملNonthermal X-ray Emission from the Shell-type Snr G347.3−0.5
Recent ASCA observations of G347.3−0.5, an SNR discovered in the ROSAT All-Sky Survey, reveal nonthermal emission from a region along the northwestern shell (Koyama et al. 1997). Here we report on new pointed ASCA observations of G347.3−.5 which confirm this result for all the bright shell regions and also reveal similar emission, although with slightly different spectral properties, from the r...
متن کاملEvidence for TeV gamma - ray emission from the shell type SNR RX J 1713 . 7 − 3946
We report the results of TeV gamma-ray observations of the shell type SNR RX J1713.7−3946 (G347.3−0.5). The discovery of strong non-thermal X-ray emission from the northwest part of the remnant strongly suggests the existence of electrons with energies up to ∼ 100 TeV in the remnant, making the SNR a good candidate TeV gamma-ray source. We observed RX J1713.7−3946 from May to August 1998 with t...
متن کاملSNR Scalability with Matching Pursuits
In this paper, SNR scalable representations of video signals are studied. The investigated codecs are well suited for communications applications because they are all based on backward motion-compensated predictive coding, which provides the necessary low-delay property. In a Very-Low Bit Rate context (VLBR), the Matching Pursuits signal representation algorithm is used to represent the Displac...
