Superconducting Transition Temperature Determination

Published Date: 23 Feb 2018

24 Pages (9,206 Words)

Fabrication of YBa2Cu3O7-Î´ and Determination of its Superconducting Transition Temperature A superconducting material is one which below a certain critical temperature exhibits, amongst other remarkable traits; a total lack of resistivity, perfect diamagnetism and a change in the character of the specific heat capacity. The BCS theory describes perfectly the phenomenon of superconductivity in low temperature superconductors, but cannot explain the interaction mechanism in high ...

Electroencephalogram Test on Alcoholics and Non Alcoholics

Published Date: 23 Feb 2018

38 Pages (14,930 Words)

INTRODUCTION The electroencephalogram (EEG) is a measurement of the electrical activity in the patient's brain. This electrical activity is produced by the firing of neurons (a nerve cell) within the brain and varies from patient to patient. In 1875, English physician Richard Caton discovered the presence of electrical activity in the brain; however, it was not until German neurologist Han Berger in 1924 used his ordinary ...

Treating Cystic Fibrosis with Gene Therapy

Published Date: 23 Feb 2018

21 Pages (8,001 Words)

In this dissertation we shall consider the field of gene therapy in specific relation to cystic fibrosis. We examine the different delivery vector mechanisms that have already been explored and concentrate primarily on the adeno-associated vectors. We examine the current state of research and consider the advantages and drawbacks of the various methods considered. We conclude with a discussion and analysis of our findings and make ...
