It is estimated that there are about 10 million organic chemicals known, and about 100,000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR, UV/visible, infrared spectroscopy, mass spectrometry, and X-ray crystallography. Of all the instrumental techniques listed, infrared spectroscopy and mass spectrometry are the two most popular techniques, mainly because they tend to be less expensive and give us the most ...

James Thompson's incomparable Inspector Vaara is back in a new chilling Nordic mystery. An Estonian woman begs Inspector Kari Vaara to find her daughter, Loviise, a young woman with Down syndrome who was promised work and a better life in Finland… and has since disappeared. One more missing girl is a drop in the barrel for a police department that is understaffed and overburdened, but for Kari, the case is personal: it’s a chance for redemption, to help the victims his failed black-ops unit was intended to save, and to prove to his estranged wife, Kate, that he’s still the man he once was. His search will lead him from the glittering world of Helsinki’s high-class clubs to the darkest circles of Finland’s underground trade in trafficked women and straight into the path of Loviise’s captors, who may be some of the most untouchable people in the country.
What is the ultimate purpose of pastoral ministry? What emphases and priorities should take precedence? In the day-to-day emphasis on various pastoral roles and pragmatic concerns, what can sometimes get lost is the theological foundation for understanding pastoral ministry. James Thompson is a New Testament scholar with a concern for relating biblical studies to practical ministry. Here he does a careful study of several of Paul's epistles in order to see what Paul's vision and purpose were for his own ministry. He finds that Paul's aim was an ethical transformation of the communities (not just individuals) with which he worked, so that they would live lives worthy of the gospel until Christ's return. Using this as a framework, Thompson offers suggestions for practical application to contemporary ministry.
