Screening these polymorphisms will pave the way to better understand the molecular mechanisms of the disease, which may be useful in developing targeted therapies for INS patients.

Problem statement: Both Lean and Environmental Management System (EMS) are key business processes which are employed by companies to enhance their manufacturing process and quality performance. ISO 14001 requires a commitment to continual improvement. Yet it does not prescribe how a company should seek the continual improvement. Lean is a process improvement method that helps companies that use it to continually improve. This study analyses these two systems and provides an understanding of how these processes had contributed in improving business efficiencies. Approach: The research methodology applied in the context of this study involved both primary and secondary research methods in gaining a deeper and practical insight into the issues facing Lean and EMS integration. The primary data collection process involved the use of questionnaires for the purpose of gaining a practical insight into the research issue. The literature review summarized the evidence collected from various secondary sources to enable an understanding of the scope, benefits and application of Lean and EMS systems. Results: The findings contributed to the framing of new conceptual framework that combines the benefits of both Lean and EMS principles for enhanced business results. Conclusion: This study concluded that an integrated business model can help organisations realize potential benefits and possibilities in the field of business enhancement

Problem statement: Whitefly, Bemisia tabaci is an important sucking pest of field, horticultural and ornamental plants causing feeding injuries besides spreading disease by acting as a vector of Gemini viruses. The polyphagous nature of the pest makes it as a highly complex species. Approach: The influence of host plants utilized by the species on the population differences at molecular level was attempted using Random Amplified Polymorphic DNA (RAPD) markers. Results: Ten RAPD primers out of the total seventeen primers screened produced 236 markers. The total number of bands obtained from each primer ranged from 11-35 with an average of 23.60 bands per primer. Of the pair wise combination among thirteen species, Srivilliputhur population showed the highest similarity index (0.826) while the lowest (0.111) was recorded by Namakkal population. The similarity coefficient based on the 236 RAPD markers generated ranged from 0.111-0.826. Three major clusters were formed from UPGMA dendrogram, which was constructed based on Jaccard's similarity. PCR screening demarcated the whitefly population based on the host species. The first cluster included population collected from okra and cotton, while second cluster comprised of population from eggplant and cauliflower and the third cluster included population from eggplant. It could be deduced that population from cotton and okra had 50% similarity, while 60-70% similarity was observed for population from eggplant and cauliflower. Conclusion: Our investigation offered the lead that within a narrow geographical region there exits variation based on host plants being utilized by the whitefly population.
