Efficient Energy Harvester for Microbial Fuel Cells using DC/DC Converters Abstract— Microbial fuel cell (MFC) is an emerging technology for sustainable energy production. An MFC employs indigenous microorganisms as biocatalysts and can theoretically convert any biodegradable substrate into electricity‚ making the technology a viable solution for sustainable waste treatment or autonomous power supply. However‚ the electric energy currently generated from MFCs is not directly usable due to the low

Question 1: Explain the gender polarization in TVET and how it can be minimized. Gender is a social construction of the idealized masculine or feminine roles and abilities by the society. Societal norms and value system has therefore been used to describe the being of a man or a woman in relation to various activities. Gender polarization is the differences in positions‚ favors’‚ opportunities and consideration occasioned by the difference in gender. Gender parity in TVET is evident in respect

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Republican-dominated one from the 1950s to the 1990s. Fenno’s goal was to provide an in depth look at this dramatic change that impacted the South and the entire nation. He also sought to examine these relationships as a cause in the increasing "polarization‚ along party lines" of the House of Representatives which made Congress "less civil‚ less manageable‚ and‚ to many‚ a less satisfying process" (p. 151). In order to conduct this study‚ Fenno examined the careers and role of Democratic Congressman

Nathan Vickers 6B Complex Characters Cambridge and The Great Gatsby are two novels which have been dubbed as successes by critics. “An American classic” raves critic John Greene about Gatsby “I think this is the best of Caryl Phillips’ novels‚ a brilliant story of the ambivalences and contradictions and hypocrisies in a slave-owning colonial society.” says Garrett Wilkes. These are just a few of the positive receptions

The author expresses his theses and opinions in this book. Firstly‚ Berghahn´s position regarding the debates over the Deutschen Sonderweg is balanced and his main view about the German population is that it was characterized by pluralization and polarization. In particular‚ the society became more pluralistic after 1871 demonstrated by a more colorful and dynamic Kaiserreich. Berghahn demonstrated this richness and
