The tryptophan residues play important roles in DNA photoreactivation catalyzed by CPD photolyases. We have investigated the action mechanism concerning Trp in DNA photoreactivation, and obtained the results as follows: 1 We proposed a mechanism of photosensitized splitting of CPDs by Trp and Trp-containing peptides. 2 Quantum yields of splitting of the model compounds that a Trp linked covalently a CPD were obtained under 290 nm light in various solvents, these values changing with solvent, range from 0.01 to 0.5. 3 Utilizing pulse radiolysis technique, splitting processes were observed in aqueous solution of the CPDs with hydrated electron and some oxidative species (such as hydroxyl radical, bromic radical and azide radical), and obtained their rate constants. In the case of interaction between CPD and hydrated electron, splitting of the CPD anion, and pyrimidine anion transfer an electron to FAD or Rf, were observed. The process rate was slower one order more than that in photolyase. Minor, but highly mutagenic UV-light-induced lesions are (6-4) photoproducts, which are repaired by (6-4) photolyases. These enzymes, discovered in 1993, are not well characterized and their mechanism is still under investigation.

After finishing her BTech in Architectural Engineering from NIT- Calicut in 2000, Monika studied for Master's Degree in "IT in Building Science", a two year masters program from IIIT-Hyderabad in 2003, which enables architects with software engineering expertise to understand and write their own software tools.

In 1993, professor Michael Hammer of MIT and James champy co-author the book of Reengineering the corporation ----- a Manifesto For Business Revolution, put forward the concept of BPR. BPR's central thoughts is to redesign the business process, produces the valuable result, decrease cost, improve the quality, speed and service, finally improve the performance of enterprises from the customers' need taking the business process as reforming objective.

业务流程再造（Business Process Reengineering ――BPR）概念的提出是1993年，美国麻省理工学院迈可·哈默教授与詹姆斯·钱辟合著的《再造公司――企业革命的宣言》（Reengineering The Corporation ――A Manifesto For Business Revolution）一书，其概念的核心含义就是指从顾客的需求出发，以企业流程为改造对象，对企业流程进行根本性的思考和分析，通过对企业流程构成要素的重新组合，以此实现企业业务流程彻底的重新设计，产生出更为有价值的结果，在成本、产品质量、服务和速度等方面获得戏剧化的改善，从而获得企业绩效的巨大改善。

In the case of 10% reflectivity, less than 3.7ns with 8.6:1 pulse-compression ratio has been observed. As our acknowledgement, that is the first reported.In addition, a new type of phase conjugator using tapered fiber is designed, which combined the higher reflectivity of small core-diameter fiber and higher damage threshold of large core-diameter fiber.
