There has been a large increase in the commercial use of integrated crop/pest management methods for pest and disease control on a wide range of crops throughout the world since the first edition of this book. The completely revised second edition of the bestselling Biological Control in Plant Protection: A Color Handbook continues the objective of providing a handbook with profiles and full-color photographs of as many examples of biological control organisms from as wide a global area as possible. It is designed to help readers anticipate and recognize specific problems of pest management and then resolve them using the natural enemies of pests-parasites, predators, and pathogens.
The purpose ofthis book isto provide acritical appraisal oftheconcept thatschizophreniacan becaused by viralinfections. The ability of viruses to cause psychiatric symptoms is not in question - the mental depression following a bout with mononucleosis or hallucinations associated with herpesencephalitisarewell-described examples. However, aviraloriginfor chronic disorders such as autism, schizophrenia, and bipolar disorder, is another matter. The claim of an infectious etiology for these disorders has beenmetinthemainstream scientific community byavagueskepticism that occasionally erupts into stringent criticism. Too often, however, the viral hypotheses of these disorders is simply disregarded; marginalized with the hopethat itwillgoaway sothatthe "serious" researchaimed atuncovering therealcauseoftheseillnesses willnotloseitsfocus.This beingsaid, much of the criticism is valid, and as a researcher with formal training in both neuroscience and viral immunology, I view the proposed viral etiology of thesedisorderswithaskepticaleye. Nevertheless, one cannot ignore the growing number of well-performed studies pointing to the role of viral infections as important antecedents of schizophreniaand other disorders inthe schizophreniaspectrum. Inthe last 30 years there have been hundreds of articles in peer-reviewed journals presenting evidenceorpositingtheoriestosuggestthatatleastsomecasesof schizophrenia have a viral origin. Moreover, many schizophrenia experts have been calling for the recognition that schizophrenia isa heterogeneous group of disorders that may have different causes. This idea of disease heterogeneity is reaching a crescendo, and there is undoubtedly a place for viruses among alternative etiologies; but we have to look. The intellectual climate tolooknowisbetterthanitwas20yearsago, inpartbecause inthe last 2 decades a number of chronic diseases of unknown etiology (e.g. gastric ulcers, Kaposi's sarcoma, hepatocellular carcinoma) have been ascribedtoinfectiouscauses.
Corrosion is a naturally occurring cost, worth billions in the oil and gas sector. New regulations, stiffer penalties for non-compliance and aging assets are all leading companies to develop new technology, procedures and bigger budgets catering to one prevailing method of prevention, cathodic protection. Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries trains on all the necessary reports, inspection criteria, corrective measures and critical standards needed on various oil and gas equipment, structures, tanks, and pipelines. Demands in the cathodic protection market have driven development for better devices and methods, helping to prolong the equipment and pipeline's life and integrity. Going beyond just looking for leaks, this handbook gives the engineer and manager all the necessary tools needed to put together a safe cathodic protection system, whether it is for buried casing while drilling, offshore structures or submarine pipelines.
