Abstract As the main load-bearing component of aero-engine system, thin-walled casings have characteristics large size, complex structure, thin wall, and area. In addition to harsh working environment, it is necessary study applicable preventive measures contain high-energy fragments ensure flight safety. The load formed by axial impact circumferential torsion exerted turbine rotor on exhaust c...

Slender concrete walls incorporated into tilt-up construction over the past 60 years have performed remarkably well under out-of-plane wind and seismic loads. While issues associated with seismic wall anchorage gave this form of construction a black-eye in the early days, the concrete walls themselves have always performed very well even as far back as their first use in the early 1900s. Yet th...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...

We evaluated the potential utility of hydrogels for delivery of the photosensitizing agents 5-aminolevulinic acid (ALA) and hematoporphyrin monomethyl ether (HMME) to rectal tumors. Hydrogel suppositories containing ALA or HMME were administered to the rectal cavity of BALB/c mice bearing subcutaneous tumors of SW837 rectal carcinoma cells. For comparison, ALA and HMME were also administered by...

Abstract The performance of textile reinforced concrete composite panels (TRCCPs) under the action pseudo-static load up to collapse was evaluated. test TRCCPs axial and transverse loading conducted, results were compared with those for steel wire mesh reinforced-concrete (SMRCCPs). Ceram-site utilized as panel matrix owing its lightweight insulation characteristics. ultimate bearing capacity, ...

We describe a sentence-level opinion detection system. We first define what an opinion means in our research and introduce an effective method for obtaining opinion-bearing and nonopinion-bearing words. Then we describe recognizing opinion-bearing sentences using these words We test the system on 3 different test sets: MPQA data, an internal corpus, and the TREC2003 Novelty track data. We show ...

Abstract Euhedral andradite crystals were found in trachyandesitic (latitic) lavas of the volcanic Andahua Group (AG) Central Andes. The AG comprises around 150 centers, most wich are monogenetic. studied is complexly zoned (enriched Ca and Al its core mantle, Fe this compositionally homogenous rim). core-mantle regions contain inclusions anhydrite, halite, S- Cl-bearing silicate glass, quartz,...
