Fluorinated quaternary ammonium-containing polymers were used as catalyst binders in microbial fuel cell (MFC) cathodes. The performance of the cathodes was examined and compared to NAFION and other sulfonated aromatic cathode catalyst binders using linear sweep voltammetry (LSV), impedance spectroscopy, and performance tests in single chamber air-cathode MFCs. The cathodes with quaternary ammo...

The dynamic method of generating reference Volatile Organic Compounds (VOC) mixtures at trace level requires the uninterrupted blending of the component flows. The accurate control of the dilution air flows can be realized by Mass Flow Controllers (MFC). Accuracy and stability of MFC are here measured and discussed in order to verify their use in dynamic gas dilutors. Long term stability confir...

A clear understanding of the pharmacodynamic properties of antifungal agents is important for the adequate treatment of fungal infections like candidiasis. For certain antifungal agents, the determination of Minimal Fungicidal Concentration (MFC) and time kill curve could be clinically more relevant than the determination of the Minimal Inhibitory Concentration (MIC). In this study, MIC and MFC...

Making an error elicits activity from brain regions that monitor performance, especially the medial frontal cortex (MFC). However, uncertainty exists about whether the posterior or anterior/rostral MFC processes errors and to what degree affective responses to errors are mediated in the MFC, specifically the rostral anterior cingulate cortex (rACC). To test the hypothesis that rACC mediates a t...

Anaerobic bacteria were isolated from industrial wastewater and soil samples and tested for exoelectrogenic activity by current production in double chambered microbial fuel cell (MFC), which was further transitioned into a single chambered microbial electrolytic cell to test hydrogen production by electrohydrogenesis. Of all the cultures, the isolate from industrial water sample showed the max...

Introduction Correlation of quantitative MRI with brain iron may provide a useful tool in the diagnosis and prognosis of neuropathology such as Multiple Sclerosis, Alzheimer’s and Parkinson’s Disease. Several different MR measures of brain iron have been proposed ([1] and references therein). The aim of this work was to compare three of the most promising, namely: transverse relaxation rate, ma...

PURPOSE To report 2 cases of delayed spontaneous Descemet membrane (DM) reattachment following big-bubble deep anterior lamellar keratoplasty (DALK). METHODS A 21-year-old man with keratoconus and a 36-year-old woman with corneal macular dystrophy underwent big-bubble DALK. No injury to DM was noted intraoperatively or postoperatively. Postoperatively, the patients developed central DM detach...

Recently Dent and Mercer have introduced an algorithm called minimal forward checking (MFC) which always performs no worse than forward checking (FC) in terms of number of compatibility checks and node expanded given the same variable and value orderings. In this paper we describe an algorithm which extends MFC with backmarking and conflict-directed backtracking. The new algorithm has a smaller...

The degree of fat deposition in muscle and its implications for obesity-related complications in children and youths are not well understood. One hundred and fifty-nine patients (mean age: 13.3 years; range: 6-20) with a body mass index (BMI) >90(th) percentile for age and sex were included. Muscle fat content (MFC) was measured in the psoas muscle by proton magnetic resonance spectroscopy. The...
