AN AES INVESTIGATION OF ALUMINUM, Al OXIDE AND Al NITRIDE

The aluminum-L,,VV Auger spectra for elemental Al. Al oxide and Al nitride have been measured in an assessment of the utility of Auger spectroscopy in characterizing thin oxidized Al films used in model supported-metal catalyst studies. Clearly distinct spectra were found for the three surface chemical states. The oxide spectrum was shown to be similar to published spectra from bulk, single-cry...

DIMAGGIO ET AL. SOCIAL IMPLICATIONS OF iNTERNET

The Internet is a critically important research site for sociologists testing theories of technology diffusion and media effects, particularly because it is a medium uniquely capable of integrating modes of communication and forms of content. Current research tends to focus on the Internet’s implications in five domains: 1) inequality (the “digital divide”); 2) community and social capital; 3) ...

Snail1 and Zeb1 are E-cadherin-transcriptional repressors induced during epithelialmesenchymal-transition (EMT). In this article we have analyzed the factors controlling Zeb1 expression during EMT. In NMuMG cells treated with TGF-β, Snail1 RNA and protein are induced one hour after addition of the cytokine preceeding Zeb1 up-regulation that requires six to eight hours. Zeb1 gene expression is c...

Bi-concave Functions Defined by Al-Oboudi Differential Operator

The purpose of the present paper is to introduce a class $D_{Sigma ;delta }^{n}C_{0}(alpha )$ of bi-concave functions defined by Al-Oboudi differential operator. We find estimates on the Taylor-Maclaurin coefficients $leftvert a_{2}rightvert $ and $leftvert a_{3}rightvert$ for functions in this class. Several consequences of these results are also pointed out in the form of corollaries.
