in this paper, an effective numerical method is introduced for the treatment of nonlinear two-dimensional volterra-fredholm integro-differential equations. here, we use the so-called two-dimensional block-pulse functions.first, the two-dimensional block-pulse operational matrix of integration and differentiation has been presented. then, by using this matrices, the nonlinear two-dimensional vol...

BACKGROUND The socio-economic gradient in health does not seem to apply to overweight among Canadians adults. In the present study, we sought to determine the socio-economic gradient in overweight among Canadian children in distinct economic settings. We further examined socio-economic gradients in underlying behaviours, healthy eating and active living, as well as parental support for these be...

The SEDO project develops a platform combining fast access, user freedom, and coherence of the results for presenting complex socio-economic data. As an initial yield, this joint project involving two research actors of Luxembourg, the CEPS/INSTEAD for the content and the CRP-Gabriel Lippman for the technical realization, will deliver on the Net the results of longitudinal surveys about the lif...

background: this paper proposes a new emotional stress assessment system using multi-modal bio-signals. electroencephalogram (eeg) is the reflection of brain activity and is widely used in clinical diagnosis and biomedical research. methods: we design an efficient acquisition protocol to acquire the eeg signals in five channels (fp1, fp2, t3, t4 and pz) and peripheral signals such as blood volu...

Objective(s): Microarrays are potential analyzing tools for genomics and proteomics researches, which is in needed of suitable substrate for coating and also hybridization of biomolecules.   Materials and Methods: In this research, a thin film of oxidized agarose was prepared on the glass slides which previously coated with poly-L-lysine (PLL). Some of the aldehyde groups of the activated aga...

political legitimacy is one of the fundamental notions in contemporary political theorizing. to explain this notion, a set of views, influenced by weber, put emphasis on the role of political beliefs of the citizens. yet, recent academic enterprises refer to the political agents, focusing on their actions. this article studies iranians’ socio-economic conditions in 1990’s, and reveals the setti...
