< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

CMOS Scaling technologies are the main caused for great impact on Analog design. The most severe affect is the reduction in the voltage supply. A double balanced down conversion oscillator mixer using 90 nm CMOS technology is proposed in this work. This oscillator mixer consists of an individual mixer stacked on a voltage-controlled oscillator (VCO). The proposed stacked structure allows entire...

BACKGROUND Unchanged substrate in a negative rapid urease test may be reused to detect Helicobacter pylori (H. pylori). This could potentially reduce costs and wastage in low prevalence and resource-poor settings. We thus aimed to investigate the diagnostic accuracy of reused Pronto Dry and CLOtest kits, comparing this to the use of new Pronto Dry test kits and histopathological evaluation of g...

In this paper, we propose a coverage measurement protocol (CMP) which can provide the base station an accurate and in-time measurement of the current connected coverage in an energy-efficient way, and our CMP is location-error tolerant. Moreover, the major component of our CMP, i.e., BOundary Node Detection (BOND) scheme, can be reused to provide many other functionalities for WSNs.

Rhodium(0) nanoparticles stabilized by a polymer containing carboxylate and β-cyclodextrin moieties have high stability and catalytic activity for aqueous hydrogenation reactions of olefins and aromatic substrates. This catalytic system can be recycled and reused without loss of activity. These high catalytic performances can be attributed to conjugated electrostatic interactions (carboxylate g...

The paper in its current form is meant to be an essay, written as part of the evaluation of the students that participated in the IPICS2000 summer school. Later it will probably be reused to write a more detailed technical report about this matter. Therefore, please take into account that it sometimes resembles more like the latter.

A flexible software based platform for number plate recognitions applications is described. It breaks the processing into several explicit modules, with the implementation for each module provided by a software plugin using a DLL interface. The modular structure greatly facilitates the comparison between different algorithms for a particular step, and allows code to be reused between applications.
