This paper describes the Utah State University (USU) entry in the 2002 robotic Urban Search and Rescue (USAR) competition, hosted by the American Association for Artificial Intelligence (AAAI). More importantly, it also describes the problems the team encountered in preparing for this year’s competition, the lessons learned, and plans for the 2003 USAR competition. Description of the 2002 Entry...

A simple and novel method for the colorimetric detection of Co(2+) was developed based on controlling the oxidation level of methylene blue (MB). After a complex was formed between MB, 2-aminothiophenol (ATP) and copper nitrate (MB-ATP-Cu(2+)), the sensing of Co(2+) showed high selectivity. The mechanism of sensing has also been discussed.

In the title coordination polymer, [HgBr(2)(C(14)H(10)N(4)S(2))](n), the Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by the two N atoms of the pyridyl groups of different 3,6-bis-(2-pyridyl-sulfan-yl)pyridazine ligands and two Br atoms. The bridging function of the cis ligands leads to a helical chain structure along [100].

immobilization of catalysts on the surface of some inert supports makes therecovering step easier. because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. in this study, zeolite x was synthesized by natural kaolin and tio2 was incorporated into zeolite phase by impregnation method. degradation of safranin orange, methylene blue and 2,4–dinitroanilin...

Conversion should not be a problem. It is best to use a general accepted tool, which comes with a preprint format. Until BLUe’s format is generally accepted a BLUe script has to converted to comply with publishers’ formats to get it out. Conversion via TEX’s expansion is exercised in this note, with as result a plain TEX Convertor Assistant, in the spirit of AWK. In netland it does not matter b...

fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...
