Superconducting Transition Temperature Determination

23 Feb 2018

24 (9,206 )

Fabrication of YBa2Cu3O7-δ 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 ...

Novel Planar Nanodevices for Chemical Sensing Applications

23 Feb 2018

31 (12,331 )

In recent years, planar electronic nanodevices have attracted much attention due to their simple architecture, ease of fabrication and low cost of manufacture. Such devices address a wide variety of applications in printed and plastic electronics industry. Using this approach a new type of sensor, which is sensitive to different chemicals, has been developed and reported here. By exploiting the unique characteristics of semiconductor asymmetric nanochannels, ...

Electroencephalogram Test on Alcoholics and Non Alcoholics

23 Feb 2018

38 (14,930 )

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

23 Feb 2018

21 (8,001 )

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 ...
