作者： Richard Harwood ian lodge

ISBN: (纸本)9781107615038

This edition of our successful series to support the Cambridge IGCSE Chemistry syllabus (0620) is fully updated for the revised syllabus from first examination from 2016. Written by a team with teaching and examining experience, Cambridge IGCSE Chemistry Coursebook with CD-ROM gives comprehensive and accessible coverage of the syllabus. Suggestions for practical activities are included, designed to help develop the required experimental skills, with full guidance included on the CD-ROM. Study tips throughout the text, exam-style questions at the end of each chapter and a host of revision and practice material on the CD-ROM are designed to help students prepare for their examinations. Answers to the exam-style questions in the Coursebook are provided on the CD-ROM.

BACKGROUND:Spontaneous hemoperitoneum of hepato- biliary origin is commonly due to hemorrhage from a liver *** is rarely caused by spontaneous rupture of aneurysm in visceral arteries. METHODS:We report an unusual case of hemoperitoneum caused by rupture of cystic artery pseudoaneurysm,and also outline the approach to its management through surgical and radiological methods. RESULTS:In our patient,the pseudoanurysm was initially treated with percutaneous thrombin *** this method of treatment failed after initial *** pseudoanurysm was finally obliterated successfully using microcoil embolization. CONCLUSIONS:The mainstay of treatment of cystic artery pseudoaneurysm is cholecystectomy and ligation of the *** publications showed success in using microcoil *** this case we also outline the use of percutaneous thrombin injection as a definitive treatment method and discuss its success or failure as a new method of treatment.

＜正＞Introduction The influence of perennial grasses on the soil water balance has been determined by measuring the pattern and depth of soil drying achieved by plant roots（Murphy and lodge 2006）.Pasture species having a greater plant root depth and an increased ability to use available soil water may produce more herbage mass,and so increase livestock *** North-West Slopes region of New South Wales（NSW） is classed as a temperate environment,but it has warm to hot summers and a summer dominant rainfall *** active species,such as tropical perennial grasses,may be suited to this environment to utilise available soil water during the summer season.
