In this work, the carboxylic acid derivatives of a free-base porphyrin, 5,10,15,20-tetrakis(4-carboxyphenyl)-21H,23H-porphyrin, and 10 of its metal derivatives (TCPPs) have been used for optical gas sensing. For this purpose, microstructured columnar TiO(2) thin films prepared by GAPVD (glancing angle physical vapor deposition) have been used as host materials for the porphyrins as they are non...

Preputial gland is one of the prime sources of pheromones in rats. The study on pheromone identification in preputial gland is well established in laboratory rat, house rat and voles. But the study was lacking in the preputial gland of bandicoot rats. Hence, the present investigation was aimed to identify the volatile and protein profiles of preputial gland of male bandicoot rat. Gas chromatogr...

This book presents the latest techniques for characterization, modeling and design for nano-scale non-volatile memory (NVM) devices. Coverage focuses on fundamental NVM device fabrication and characterization, internal...

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...

However brilliant a scientist is, however incisive their mind and however elegant their experiments, they must be able to communicate effectively. The ability to write fluently, to inspire an audience in a lecture hall, and to listen carefully and argue cogently face-to-face with a sceptic are all important. Maybe some people believe that it’s only important to impress the journal referees and ...

Although viscosity (mu) is a crucial factor in measurements of flow with a pneumotachograph, and density (rho) also plays a role in the presence of turbulent flow, these material constants are not available for the volatile anaesthetic agents commonly administered in clinical practice. Thus, we determined experimentally mu and rho of pure volatile anaesthetic agents. Input impedance of a rigid-...

A diffusion chamber is described which concentrates short-chain, volatile fatty acids from seawater while simultaneously separating them from interfering salts. The procedure relies on the passive diffusion of volatile compounds from acidified seawater samples and their subsequent absorption onto a base-impregnated filter. The method is simple, efficient, and adaptable to most commonly used met...
