I give gratitude and glory to Almighty God for His mercies and gift of healthy life. I take immense pleasure in thanking my supervisor, Madam Roxana Gathogo for her advice, guidance, motivation and support during the project development. Her guidance and advice always inspired me to seek more knowledge in solving all the challenges I faced throughout this project. Needless to mention all lecturers in the department for the role they played in moulding me to be what I am today. Words are inadequate in offering my thanks to my colleagues in class for their encouragement and cooperation in carrying out the proposal work. I would like to express my heartfelt thanks to my brother Stephen Peter, my father Peter and my mother Rabecca, other family members, friends and co-workers for their tolerance, blessings, moral and material support.May God bless you all.
