Awide range of pulmonary pathology is attributed to aluminum dust exposure, including interstitial fibrosis^1-5 desquamative interstitial pneumonia^6 and pulmonary alveolar proteinosis^7 To our knowledge, granulomatous lung disease induced by aluminum dust is rare, only two cases were reported in literatures^8.9 We had the opportunity to make a diagnosis of pulmonary sarcoid-like granulomatosis in a patient exposed to aluminum dust. Herein, we report the clinical history, radiographic and histopathological findings in this patient, and the detailed mineralogical analyses performed on lung tissue obtained by open lung biopsy.

Research in Astronomy and Astrophysics 2016年第11期16卷 29-36页

作者： Xian-min meng Xu-Hui Han Jian-Yan Wei Jing Wang Li Cao Yu-Lei Qiu Chao Wu Jin-Song Deng Hong-Bo Cai Li-Ping Xin Key Laboratory of Space Astronomy and Technology National Astronomical Observatories Chinese Academy of Sciences

We present a star catalog extracted from the Lunar-based Ultraviolet Telescope （LUT） survey program. LUT＇s observable sky area is a circular belt around the Moon＇s north pole, and the survey program covers a preferred area of about 2400 deg2 which includes a region of the Galactic plane. The data are processed with an automatic pipeline which copes with stray light contamination, artificial sources, cosmic rays, flat field calibration, photometry and so on. In the first release version, the catalog provides high confidence sources which have been cross-identified with the Tycho-2 catalog. All the sources have signalto-noise ratio larger than 5, and the corresponding magnitude limit is typically 14.4 mag, but can be as deep as -16 mag if stray light contamination is at the lowest level. A total of 86 467 stars are recorded in the catalog. The full catalog in electronic form is available online.

Oxidation resistance enhancement of pure Ti often comes at the cost of reduced ductility,which is frequently the problem through alloying with sole Al,Si,W,Mo and *** overcome the short coming of single element alloying,this paper proposes a multi-element low-alloying strategy to take advantage of synergistic effects and resolve the conflict between oxidation resistance and *** demonstrates that the addition of a small quantity of Ta(0.51wt%)can boost both oxidation resistance and ductility in comparison to pure ***,the combined addition of a small amount(0.54 wt%)of Ta,Nb and Si not only preserves good ductility of pure Ti,but also reduces mass gains to 14%-67%of pure Ti during 100 h oxidation at 650-850℃in *** indicates even better oxidation resistance than that obtained through the use of Ta,Nb,or Nb+Ta *** Ta+Nb+Si alloying creates an oxide layer that is less porous and more resistant to stratification and ***,a 3-μm N-rich layer can form in the Ti substrate beneath the oxide scale,in which phase transformation generates coherent Ti_(2)N with(0001)_(Ti)as the habit plane,with N atoms prefers to diffuse along■than along[0001]_(Ti).The completely transformed Ti_(2)N region or partially transformed Ti+Ti_(2)N region can effectively impede oxygen ***,the multielement low-alloying strategy is promising for enhancing both oxidation resistance and mechanical properties of metallic materials in the future.

There are a wide range of computed tomography （CT） findings in patients with pulmonary tuberculosis, including diffuse or localized nodules, reticular opacities, ground glass attenuation, air trapping, consolidation, cavitation, fibrosis, lymph nodes enlargement, and septal thickening. However, CT findings of pulmonary tuberculosis that appeared as multiple cystic lesions were very rare. Herein, the CT findings appeared as multiple cystic lesions in a patient with pulmonary tuberculosis are reported.
