Microbial Quality of Aquaculture Water Used for Produce Irrigation
(2018-07-23)
The use of recycled water from an aquaculture fish tank to irrigate produce, or aquaponics, has grown rapidly in the past decades, with a large diversity of system designs. Since the water is reused from the fish tank, ...
Microbiological Evaluation of Commercially Manufactured Animal Feeds to Determine Presence of Salmonella, Escherichia coli and Clostridium perfringens
(2020-07-14)
Animal feed can potentially expose animals to pathogens which may lead to infection or colonization of the gastrointestinal tract (GIT). Feeds can become contaminated with bacterial pathogens during harvesting/transportation ...
Microcapsule based self-healing for 3D printed polymer composites
(2019-07-16)
Polymer composites are widely used in many industries due to their superior properties. Many of these composites are 3D printed to allow for greater customization and control over the properties. However, the replacement ...
Microcontroller-Based Current-Mode Control for Power Converters
(2005-12-15)
Presented in this dissertation is the implementation of microcontroller-based digital current-mode control (CMC) switch-mode power converters. A hybrid control method is proposed. By using on-board analog peripherals on ...
Microfabricated Electrode Arrays Suitable for Stimulation and Recording in Cardiac Electrophysiological Studies
(2008-05-15)
Sudden cardiac arrest (SCA) caused by ventricular fibrillation is one of the most serious heart related problems in the United States today which is responsible for hundreds of thousands of deaths per year. The goal of ...
Microfibrous Entrapped Catalysts and Sorbents: Microstructured Heterogeneous Contacting Systems with Enhanced Efficiency
(2008-05-15)
Catalyst/adsorbent particles were entrapped in sinter-locked networks of
microfibers to form composite materials for use in heterogeneous catalysis and adsorption applications. These novel microstructured materials called ...
Microfibrous Entrapped Catalysts for Low Temperature CO Oxidation in Humid Air
(2013-05-14)
CO oxidation at ambient conditions poses a major challenge due to CO self-poisoning at low temperature as well as passivation of the catalyst in the presence of moisture. A highly active novel catalyst has been developed ...
