Abstract This experimental study was aimed to investigate the microwave absorbing properties of composites with different structures prepared by filling nitrile rubber (NBR) ferrite and acetylene carbon black (CB). The results show that input impedance ferrite-filled composite smaller than CB-filled composites. filled also matched free space better CB composite. two-layer four-layer performed s...

Many fMRI experiments show regions of cortex that seem to respond in antiphase with the primary stimulus. In this issue of Neuron, Shmuel et al. show that this "negative BOLD response" is spatially and temporally linked to reductions in blood flow. By combining BOLD and blood flow data to model the energy consumption in cortex, they conclude that the NBR is primarily due to active neuronal inhi...

Abstract Nanocomposites based on acrylonitrile butadiene rubber (NBR) and ethylene–proplene diene monomer (EPDM) (50/50) filled with different concentrations of nano-waste magnetic filler (nWMF) up to 120 phr were prepared by two laboratory roll mill mixer. nWMF was characterized using XRD, TEM VSM. The nanocomposites investigated techniques: SEM, TGA, DSC. In addition the rheological, mechanic...

Front Cover: The effects of 4010NA content on the damping and aging properties hydrogenated nitrile butadiene rubber (HNBR)/nitrile (NBR) matrix are studied via molecular simulation experiments. With an increase in content, there is a decrease free volume fraction (FFV), attributed to hydrogen bond network between HNBR/NBR matrix. This reported by Meng Song, Qi Qin, co-workers article number 22...

In this paper, we show that simple, cheap and easily deployable honeypots can help understanding of the attack processes that machines in unclassified networks are facing knowledge is a prerequis several honeypots. We hi diverse locations. Such an open issues described here after. 1.0 INTRODUCTION Recently, several papers have explained how so-called “Internet telescopes” can be use understandi...

MicroRNAs (miRNAs) are endogenous noncoding small RNAs with important roles in many biological pathways; their generation and activity are under precise regulation [1-3]. Emerging evidence suggests that miRNA pathways are precisely modulated with controls at the level of transcription [4-8], processing [9-11], and stability [12, 13], with miRNA deregulation linked with diseases [14] and neurode...

The thermogravimetric analysis (TGA) and the differential thermal analysis (DTA) were applied to investigations of aging processes in some electroinsulating polymeric materials (glass reinforced epoxy resin, NBR ( two sorts), styrenated unsatured polyester resin, hydrogenated NBR (T80), polychloroprene rubber , EPR) and to the measurement of aging reaction rates. It is shown that thermal analys...

In this paper, the natural boundary element method (NBEM) for an anisotropic hyperbolic problem in an exterior elliptic domain is investigated. By the theory of the natural boundary reduction (NBR), the natural integral equation (NIE) and the Poisson integral formula of the problem considered are obtained, and the numerical method of the NIE is given. Finally, some numerical examples are presen...
