However, contrary to the belief that the DB procurement will result in better project outcomes, many of the projects operated on the DB fell short of meeting the expectations. Some ended with worse than when operated with the traditional procurement system. The adequacy of the DB implementation process in Malaysia was researched to trace the root cause that contributed to the DB project failures. The findings from the initial research which suggest the factors that contributed to the failures were culminated and discussed in a specially organized workshop. During the workshop, 28 experts representing clients, consultants and contractors with experience with DB projects were gathered to suggest what can be re-learnt from the current DB implementation process. ‘Gaps’ which suggest weakness within existing implementation process were identified and the way forward for improving the practice of DB project implementation were proposed.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125858435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, pretreatment by dilute H<inf>2</inf>SO<inf>4</inf> (2%) achieved the highest glucose yield of 39.43 g/L with glucose recovery of 98.86%. Alkali pretreatment using NaOH at different concentration shows no significant effect on the glucose generation (0.61–1.13 g/L) when NaOH concentration was increased. However, the combination of alkali pretreatment with microwave treatment resulted in a drastic increase of glucose yield in kitchen waste sample. Meanwhile, H<inf>2</inf>O<inf>2</inf> pretreatment seems to have little effect on the glucose yield (1.53–3.05 /L) when the concentration of H<inf>2</inf>O<inf>2</inf> was increased. But when this oxidizing agent was added to H<inf>2</inf>SO<inf>4</inf> and NaOH -microwave treatment, it increases the glucose yield from 10.36 to 13.31 g/L. With respect to glucose recovery, all microwave-assisted chemical pretreatment achieved the value of more than 90% glucose recovery.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121935878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural and optical characteristics of the sample have been investigated by using scanning electron microscope (SEM), atomic force microscope (AFM), high resolution X-ray diffraction (HR-XRD), Raman spectroscopy, photoluminescence (PL) and Fourier transform infra-red (FTIR), respectively. The FTIR measurement reveals that ZnO retains its wurtzite structure due to the presence of vibrations in the Zn-O bonds. XRD analysis shows that there exists a slight impurity occurring in the sample with the presence of Al2O3 and the high and sharp peak of ZnO shows the good quality of crystallinity of ZnO. Raman spectroscopy measurements reveal that the ZnO film is a single crystal and has wurtzite structure and the presence of impurities such as oxygen deficiencies and interstitial defects. The PL spectra clearly prove that the Zn has high crystal quality due to the very high and sharp peak at wavelength of 390 nm. The deep level emissions also show that there is an oxygen defects in the ZnO film. The deposition of ZnO film onto Si substrate through RF sputtering results in the ZnO film having high quality crystal structure with the presence some impurities and defects.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128765440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Technology diffusion and the training of staff for high-end customized systems require outsourcing vendors to be on hand most times as detailed in the contract. Once the contract ends, agency staffs are left on their own to man the system and ensure the return on investment. Limited literature and the paucity of similar projects has resulted in this study, thus, the purpose of this research is to identify the backsourcing challenges faced by government agencies after the termination of the outsourcing contract. A cross-sectional approach with triangulation was designed for data gathering and analysis in answering the research questions. A two-phase non-probability sampling ensured the scope and right data collection technique. The preliminary findings from interviews showed that government agencies are not ready for back-sourcing and the customized system implemented will not be fully utilized. Details on the challenges faced by the agency will be elucidated in the paper, however, it is recommended that the gradual relinquishing of the ownership be done a year before the contract ends. Planning and monitoring of the project is mandatory for the success in efficient knowledge transfer and effective usage of the system.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122915054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
