Bioremediation of petroleum hydrocarbons using microbial fuel cells
… effects of three selected operating parameters - external resistance, salinity and redox mediator were also investigated using response surface methodology. The outcomes of this study demonstrated the robustness of MFCs with good degradation performance (range 80 - 98 %) and maximum power …

Thermal analysis of power hybrid microelectronic packages
… represents everything below the substrate by an external thermal resistance (expressed as an equivalent convective heat transfer coefficient, h). In this study, the impact on thermal management of thick film metallization and copper cladding on alumina, aluminum nitride, and beryllia ceramic …

Melting of polymers
… of thermal conductive heating (from external resistance heaters) and viscous heating in the heating (and melting) of low density polyethylene. A model system was used in order to simplify the mathematical analysis. A theory was developed to describe both processes in the model …

DEVELOPMENT OF MICROBIAL ELECTROCHEMICAL SENSOR FOR TOXICITY SCREENING OF INFLUENT WASTEWATER
… configuration, size, flow conditions, membrane, external resistance, etc. The application of the MES to different kinds of toxicants and their characteristics were studied. Toxic compounds tested included individual heavy metal ions (Cu(II), Zn(II), Pb(II), Cd(II) and Ni(II)), binary mixtures of …

A biomechanical investigation of contemporary powerlifting training practices and their potential application to athletic development.
… 1) the practice of performing traditional resistance exercises at maximum velocity; 2) the effects of manipulating the external resistance through the use of variable resistance material (chain resistance) and an unconventional barbell (the hexagonal barbell); and 3) the effects of altering …

Self-respect and The Obligation to Resist Oppression
… this is how we see ourselves. The second is our external image; this is how we think people see us. One way we can disrespect ourselves is by causing conflict between these two elements, which undermines our self-respect. Hay's account is grounded on the oppressed person respecting themself. …

Ultrasonically Enhanced Mass Transport and Degradation of Polycyclic Aromatic Hydrocarbons in Solid-Liquid Two Phase Partitioning Systems
… delivery of PAHs was restricted by the external resistance at the solid-liquid interface. Ultrasound was shown to enhance both external and internal transport properties, allowing rates not achievable through increased liquid mixing. Diffusivities quantified with and without ultrasound …

Thermal modeling of hybrid microelectronics
… substrate thicknesses, device spacings, and external boundary conditions. They can be used to assess thermal interaction for preliminary design and layout of power devices on hybrid substrates. Previous work in this area typically deals with semi-infinite regions or finite regions with …

Asymmetric Energy Harvesting and Hydraulically Interconnected Suspension: Modeling and Validations
… absorbers to counter the road disturbances using external power input. Active suspensions such as electro-magnetic shock absorbers use the variable viscosity of magnetofluid to alter the damping characteristics of the suspension to adapt to quickly changing road conditions. The energy demand from …

Self-Healing of Open-Circuit Faults in Organic Thin-Film Transistor-Based Flexible Electronics
… these devices usually suffer from internal and external forces, which can lead to the failure of interconnects in the circuit. To address this issue, some passive and active strategies have been developed for improving the reliability of interconnects in circuits. Although all these strategies …

Mechanisms of Actomyosin Contractility in Cells
… determined by a balance between ring tension and external resistance forces. Our results describe a casual relationship between ring organization, actin turnover kinetics, tension, and constriction. Ring tension depends on ring organization through the actin and myosin concentrations and their …

Treatment of azo dyes in industrial wastewater using microbial fuel cells
… and COD removal. The use of applied external resistance (Rext) and redox mediators as tools for enhancing azo dye degradation kinetics in dual chamber MFCs was studied. The outcomes of this work suggest that azo dye reductive degradation kinetics in MFC anodes can be influenced by …

Bilateral and unilateral resistance training and athletic performance
… of training to improved athletic performance. In resistance training, it has long been identified that the closer the mechanical specificity between the training exercise and outcome performance, the greater the transfer of improved capacity. Bilateral resistance exercises are predominately …
