the cane alcohol vinasse assessment on the removal efficiency of a fixed biomass anaerobic reactor (fbar) was evaluated. crude vinasse was used to feed the reactor. the fbar was operated with organic load rate (olr) of 0.5, 1, 3 and 6 gcod/l/d. removal efficiencies of 85, 82, 75 and 66 per cent were observed respectively. the fba reactor presented an excellent removal of organic matter, however...

This theory defines a type constructor representing the free Boolean algebra over a set of generators. Values of type (α)formula represent propositional formulas with uninterpreted variables from type α, ordered by implication. In addition to all the standard Boolean algebra operations, the library also provides a function for building homomorphisms to any other Boolean algebra type. 1 Free Boo...

7-Fluorobenz(a)anthracene (7-FBA) was metabolized by rat liver microsomes predominantly to 4-hydroxy-7-FBA and 7-FBA trans-3,4-, 5,6-, 8,9-, and 10,11-dihydrodiols. Proton nuclear magnetic resonance spectral analyses indicated that the fluoro substituent causes 7-FBA trans-5,6- and 8,9-dihydrodiols to adopt preferentially quasidiaxial conformations (Chiu, P.-L., Fu, P. P., and Yang, S. K. Bioch...

Constraint-based stoichiometric models are ubiquitous in metabolic research, with Flux Balance Analysis (FBA) being the most widely used method to describe metabolic phenotypes of cells growing in steady-state. Of the many variants of constrainbased modelling methods published throughout the years, only few have focused on thermodynamic issues, in particular the elimination of non-physical and ...

Microbial pathogens often exploit human complement regulatory proteins such as factor H (FH) and factor H-like protein 1 (FHL-1) for immune evasion. Fba is an FH and FHL-1 binding protein expressed on the surface of the human pathogenic bacterium Streptococcus pyogenes, a common agent of pharyngeal, skin, and soft-tissue infections. Fba has been shown to contribute to phagocytosis resistance, i...

A retrospective study to determine how well cardiotocogram (CTG) and micro blood analysis (FBA) results correspond to each other was made on 200 deliveries which had been monitored sub partu by these techniques. FBA was performed 306 times. CTG results were analysed according to Hammacher's method and the scores compared with the FBA results. In 40 cases with a normal Hammacher score, a normal ...

Background and Aims: Foreign body aspiration (FBA) is frequently seen in children, progresses with symptoms related to airway obstruction, leading serious complications. The aim of this study was discuss the diagnosis treatment principles patients who underwent bronchoscopy for suspected foreign (FBA), emphasize its preventability. Method: A retrospective review made records evaluation FBA Pedi...

Flux balance analysis (FBA) is a linear programming-based framework widely used to predict the behavior, in terms of the resulting flux distribution, of cellular organisms in different media. FBA models are constructed using only stoichiometric information, and for this reason they sometimes fail in predicting fluxes precisely. In this work, we formally define the concept of hybrid FBA/kinetic ...

BACKGROUND Children with undiagnosed and retained foreign bodies (FBs) may present with persistent respiratory symptoms. Delayed diagnosis is an important problem in developing countries and several factors affect the delay. OBJECTIVES To investigate, the incidence of clinically unsuspected foreign body aspiration (FBA) in our flexible bronchoscopy procedures, the causes resulting in late dia...

In this issue, two studies, one by Zhou and Desimone and another by Cohen and Maunsell, provide new insights into the mechanisms of feature-based attention (FBA). The former demonstrates a new role of the frontal eye fields in the origins of FBA and the latter shows that FBA is coordinated across both hemispheres.
