Spatially offset Raman spectroscopy (SORS) for the analysis and detection of packaged pharmaceuticals and concealed drugs

Spatially offset Raman spectroscopy (SORS) is a powerful new technique for the non-invasive detection and identification of concealed substances and drugs. Here, we demonstrate the SORS technique in several scenarios that are relevant to customs screening, postal screening, drug detection and forensics applications. The examples include analysis of a multi-layered postal package to identify a concealed substance; identification of an antibiotic capsule inside its plastic blister pack; analysis of an envelope containing a powder; and identification of a drug dissolved in a clear solvent, contained in a non-transparent plastic bottle. As well as providing practical examples of SORS, the results highlight several considerations regarding the use of SORS in the field, including the advantages of different analysis geometries and the ability to tailor instrument parameters and optics to suit different types of packages and samples. We also discuss the features and benefits of SORS in relation to existing Raman techniques, including confocal microscopy, wide area illumination and the conventional backscattered Raman spectroscopy. The results will contribute to the recognition of SORS as a promising method for the rapid, chemically specific analysis and detection of drugs and pharmaceuticals.     

Intelligent agents and intentionality: Should we begin to think outside the box?

The emergence of intelligent software agents that operate autonomously with little or no human intervention has generated many doctrinal questions at a conceptual level and has challenged the traditional rules of contract especially those relating to the intention as an essential requirement of any contract conclusion. This paper will explore some of these challenges, and shine a spotlight on the conflict between the traditional contract theory and the transactional practice in the case of using intelligent software agents. Further, it will examine how intelligent software agents differ from other software applications and then consider how such differences are legally relevant. This paper, however, is not intended to provide the final answer to all questions and challenges in this regard, but to identify the main components and provide perspectives on how to deal with such issues.     

The War on Terror and the Enforced Disappearances in Pakistan

The movement against enforced disappearances has been exceptionally strong in Pakistan. It has highlighted the extralegal activities of state actors and has prompted the judiciary to question powerful agencies regarding their conduct. With the help of historical analysis, this article argues that the movement has grown out of the reactions generated by War on Terror in Pakistan. The state’s stance to override human rights for combating terrorism is challenged by a movement which is largely anti-War on Terror and which is strengthened by historical and ideological factors as well as by respect for human rights. The movement against enforced disappearances had thus paved the ground for important debates on human rights in Pakistan.     

Real‐Time Detection of Concealed Chemical Hazards Under Ambient Light Conditions Using Raman Spectroscopy

Current concerns regarding terrorism and international crime highlight the need for new techniques for detecting unknown and hazardous substances. A novel Raman spectroscopy‐based technique, spatially offset Raman spectroscopy (SORS), was recently devised for noninvasively probing the contents of diffusely scattering and opaque containers. Here, we demonstrate a modified portable SORS sensor for detecting concealed substances in‐field under different background lighting conditions. Samples including explosive precursors, drugs, and an organophosphate insecticide (chemical warfare agent surrogate) were concealed inside diffusely scattering packaging including plastic, paper, and cloth. Measurements were carried out under incandescent and fluorescent light as well as under daylight to assess the suitability of the probe for different real‐life conditions. In each case, it was possible to identify the substances against their reference Raman spectra in less than 1 min. The developed sensor has potential for rapid detection of concealed hazardous substances in airports, mail distribution centers, and customs checkpoints.     

TheMany Sounds of Civilization

<正>British-American historian Bernard Lewis famously condemned Arab and Islamic civilization for not having a polyphonic sense of music,even accusing them of accepting totalitarian ideologies and regimes because of their taste for"monophonic"music.That is,having one single singer with all the music following the ups and downs of his or her voice.Polyphonic music,by contrast,is when a piece of music has two or more independent melodies in it.As for the related notion of counterpoint,this is from many voices present in the chorus of a classical Greek drama and a reference to the coordination evident in choir singing.
