A review of some papers published in the last fifty years that focus on the semiconducting metal oxide SMO based sensors for the selective and sensitive detection of various environmental pollutants is presented. Semiconducting metal oxide sensors are one of the most widely studied groups of chemiresistive gas sensors. These sensors are designed to react with one class of gases whereby the SMO undergoes reduction and oxidation.

With increased use of explosive devices in warfare, anal trauma is often seen coupled with more complex pelviperineal injury. While the associated mortality is high, casualties that survive are often left with disabling fecal incontinence from damage to the anosphincteric complex. After resolution of the acute insult, the initial evaluation mandates a thorough physical exam, including endoscopic evaluation with rigid proctoscopy and flexible sigmoidoscopy, as well as adjunctive testing, specifically anal manometry and endoanal ultrasound.
Aims and Scope Objective Reviews in Analytical Chemistry publishes authoritative reviews by leading experts in the dynamic field of chemical analysis. The subjects can encompass all branches of modern analytical chemistry such as spectroscopy, chromatography, mass spectrometry, electrochemistry and trace analysis and their applications to areas such as environmental control, pharmaceutical industry, automation and other relevant areas. Review articles bring the expert up to date in a concise manner and provide researchers an overview of new techniques and methods.
The argument is that autonomous weapons might not just be good for national security, they would be good for human security, because they would do better than human soldiers at complying with war law. This will allegedly occur through a combination of situational judgment, ability to distinguish civilians from combatants, and good old-fashioned restraint. So the argument goes, a machine would never get tired, or go berserk when its buddy died, or make lethal mistakes due to anger, jealousy, or malice.
Bush administration. The number of detainees subjected to these methods has never been authoritatively established, nor how many died as a result of the interrogation regime, though this number is believed to be at least A Senate Intelligence Committee found photos of a waterboard surrounded by buckets of water at the Salt Pit prisonwhere the CIA had claimed waterboarding was never used.
Methods to analyze chemical warfare agents CW-agents and their decomposition products in environmental samples were developed over the last decades. In contrast herewith, procedures for analysis in biological samples have only recently been developed. Retrospective detection of exposure to CW-agents is useful for various applications. It can be envisaged that rapid diagnosis will play a pivotal role in the management of a terrorist attack with CW-agents.
