药物分析名词简释

---------------------------------------------------------------最新资料推荐------------------------------------------------------药物分析名词简释1.我国药品质量标准分为中国药典和局颁标准均属于国家药品质量标准,具有等同的法律效力。
2 中国药典的主要内容由凡例、正文、附录和_索引四部分组成。
3.精密称定系指称取重量应准确至所取重量的千分之一 ;称定系指称取重量应准确至所取重量的百分之一;取用量为约若干时,系指取用量不得超过规定量的+-10% 。
4、有机药物化学命名的根据是有机化学命名原则。
5.药品质量标准是国家对药品质量、规格及检验方法所作的技术规定,是药品生产、供应、使用、检验和药政管理部门共同遵循的法定依据。
6.INN 是国际非专利名的缩写。
1.药典中规定的杂质检查项目,是指该药品在生产过程和贮藏过程可能含有并需要控制的杂质。
2.古蔡氏检砷法的原理为金属锌与酸作用产生新生态氢,与药物中微量砷盐反应生成具挥发性的砷化氢,遇溴化汞试纸,产生黄色至棕色的砷斑,与一定量标准砷溶液所产生的砷斑比较,判断药物中砷盐的含量。
3.砷盐检查中若供试品中含有锑盐,为了防止锑化氢产生锑斑的干扰,可改用白川道夫法4.氯化物检查是根据氯化物在硝酸介质中与硝酸银作用,生成 AgCl 白色浑浊,与一定量标准 NaCl 溶液在1 / 11相同条件和操作下生成的浑浊液比较浊度大小。
5 古蔡氏检砷法中,碘化钾的作用是还原五价砷;抑制 SbH3 的生成,酸性氯化亚锡的作用是还原五价砷、抑制 SbHs 的生成、形成锌锡齐,H2 生成均匀、连续醋酸铅棉花的作用是排除H2S 的干扰,AsH3 以适宜速度通过溴化汞试纸的作用是形成砷斑 6.限量检查法的特点是:只需通过与对照液比较即可判断药物中所含杂质是否符合限量规定,不需测定___杂质具体含量__ 7.澄清度检查法是检查药品中微量不溶性杂质。

Intangible assets (IAS 38)
Definition:
Identifiable non-monetary asset without physical substance
(a) Controlled by the entity as a result past events;
Chapter 5 Intangible assets
Chapter Guide • Discuss the nature and accounting treatment of internally generated and purchased intangibles. • Describe the criteria for the initial recognition and measurement of intangible assets. • Distinguish between goodwill and other intangible assets. • Describe the subsequent accounting treatment, including the principle of impairment tests in relation to goodwill.
Probable future economic benefits Intention to complete and use/sell asset Resources adequate and available to complete Ability to use/sell asset
Technical feasibility
Goodwill
• Purchase consideration – Share of fair value of the net assets • Does NOT amortise • Impairment test annually • Negative goodwill should be recognised and w/off to income statement immediately • Disclosed separately from other intangibles
Expenditure can be reliably measured
Internally generated intangible assets
R&D
• Research expenses should be written off as incurred. • Development expenses must be capitalised if meet ‘PIRATE’ criteria. • Development expenses should be written off after recognisation if criteria are not met.
Slide 2
Exam Context • Indicate why the value of purchase consideration for an investment may be less than the value of the acquired identifiable net assets and how the difference should be accounted for. • Describe and apply the requirements of relevant accounting standards to research and development expenditure. A full question could appear in the exam on intangible assets, covering their recognition and measurement, including the treatment of research and development costs.
Goodwill
• Not recognised
Other intangible assets
• Can rarely be capitalised due to the fact that they can NOT be measured reliably (similar to goodwill)
Business combinations (IFRS 3)
Intangible assets other than goodwill
• Recongised at fair value even if not recognised at acquiree’s accounts • Amortize over useful life
and (b) Future economic benefits are expected to flow in
Measurement at recognition
Separate acquisition
Acquired as part of business combi
Internally generated intangible assets
Acquired by government grant
Cost
Fair value (IFRS 3)
NOT recognised
Only recognised if PIRATE criteria met
