the accumulative roll bonding process is used as a severe plastic deformation technique to produce aluminum composite sheets with ultra fine structure. in this study the effect of simultaneous use mg and sic particles as reinforcements, on the tensile properties of the al-mg-sic hybrid compositeis studied. the al-mg-sic hybrid composites with different amounts of mg and sic contents were fabric...

In this paper we predict that there exists an intrinsic upper limit to the beam energy of an e+e− circular collider due to the beam-beam effects. The maximum beam energy is given by E0,max = 85.17 √ NIP (GeV), where NIP is the number of the interaction points in the ring. It is concluded that LEP is the only machine on this planet which has the potential to test the validity of this theoretical...

The results of 115 bronchoscopic examinations and one autopsy in 105 adults with HIV-infection and pulmonary complications are presented. Whereas 51.7% of the events were caused by Pneumocystis carinii pneumonia (PCP), nonspecific interstitial pneumonitis (NIP) without evidence of an infectious or neoplastic condition was the second most frequent diagnosis in 14 patients (12.1%), four of whom e...

Automated methods to detect new information in clinical notes may be valuable for navigating and using information in these documents for patient care. Statistical language models were evaluated as a means to quantify new information over longitudinal clinical notes for a given patient. The new information proportion (NIP) in target notes decreased logarithmically with increasing numbers of pre...

We study and characterize stability, NIP and NSOP in terms of topological and measure theoretical properties of classes of functions. We study a measure theoretic property, ‘Talagrand’s stability’, and explain the relationship between this property and NIP in continuous logic. Using a result of Bourgain, Fremlin and Talagrand, we prove the ‘almost and Baire 1 definability’ of types assuming NIP...

In the title compound, [Ni(C(8)H(3)NO(6))(C(12)H(10)N(2))(H(2)O)](n), the Ni(II) atom is octa-hedrally coordinated by two cis N atoms from two different 1,2-bis-(4-pyrid-yl)ethyl-ene (bpe) ligands, two O atoms from one chelating carboxyl group of the 5-nitro-isophthalic acid (nip) ligand, one O atom from another monodentate nip ligand and one O atom from a water mol-ecule, forming a three-dimen...

In nature, the mechanical properties of geological bodies are very complex, and their various mechanical parameters are vague, incomplete, imprecise, and indeterminate. However, we cannot express them by the crisp values in classical probability and statistics. In geotechnical engineering, we need to try our best to approximate exact values in indeterminate environments because determining the ...

in this research the influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistors were investigated. sic was added with amounts of 10-0 mass% to zno-based varistor composition. it is found that sic allows reaching to high threshold voltage with formation of fine-grained zno.another important effect of adding sic is formation zn2sio4 (willemite) on the ...

Derives from the National Innovation System (NIS) approach, and based on some prominent weakness in China’s National Innovation System (NIS), this paper argues that China’s National Innovation Platform (NIP) program places more emphasis on the infrastructure of innovation and can be seen as an early stage to form a completed innovation system, and aims at combining the efforts and resources of ...

A systematic investigation of structural, mechanical, anisotropic, and electronic properties of SiC₂ and SiC₄ at ambient pressure using the density functional theory with generalized gradient approximation is reported in this work. Mechanical properties, i.e., the elastic constants and elastic modulus, have been successfully obtained. The anisotropy calculations show that SiC₂ and SiC₄ are both...
