When a transparency printed with a first halftone color is deposited on top of a paper printed with a second halftone color, we obtain a third color that we are able to predict in both reflectance and transmittance modes, thanks to a spectral prediction model. The model accounts for the multiple reflections of light between the printed paper and the printed transparency, which are themselves de...

It is a desirable feature in a public key infrastructure (PKI) to include the signature information in a printed document for anthenticity and integrity checks, in a way to bind an electronic document to the printed document. However, it is not easy to preserve the digital signature in the printed document because the digital signature is for the text code (or the whole document file), not for ...

In this paper we studied preparation of working films of dye-sensitized solar cells using screen printed method. The organic dye based on phenoltiazine with cyanoacrylic acid as the electron donor group utilized as photosensitizer. Fluorine-doped thin oxide FTO coated glass is transparent electrically conductive and ideal for use in dye-sensitized solar cells. FTO glass was coated by screen pri...

Printed in the Netherlands " You have walked to the edge of the great mosaic of human knowledge. Up until now, you have been living in a world full of ideas and concepts that other people have set out for you. Now it is your turn. You get to design a piece of the mosaic and glue it down. It just has to fit with what else is there. And if you do a good job shaping your tile, it will be easier fo...

Population-based carrier screening for single gene disorders has been occurring since the 1960s, with each decade bringing new opportunities and challenges. In February 2008, approximately 125 scientists, clinicians, public health officials, and patient representatives gathered to consider population-based carrier screening in light of lessons learned and emerging technologies. The following do...

Single-walled carbon nanotubes (CNTs) printed into thin films have been shown to yield high mobility, thermal conductivity, mechanical flexibility, and chemical stability as semiconducting channels in field-effect, thin-film transistors (TFTs). Printed CNT-TFTs of many varieties have been studied; however, there has been limited effort toward improving overall CNT-TFT performance. In particular...

The paper presents a research study on using teaching resources at lower secondary schools in the Moravian-Silesian Region. With regard to massive inclusion of digital and learning materials an electronic nature, aimed find out which educational are used how. methods use were deduced based activities teachers induce lessons through these resources. A qualitatively oriented design was used, in-d...

On Thursday November 19, 2008 a breakout session was held in Room B1 of the Ouaga 2000 Conference Center on the following theme: New developments in cotton ginning. The session began at 2:00 pm and ended at 3:40 pm. The meeting was well attended and the discussions were frank and direct. Four speakers were on the agenda but there were in fact three presentations, as the fourth speaker was unabl...
