In this paper, an extension of the generalized data envelopment analysis (GDEA) model has been introduced. In this generalization different cases of production possibility set (PPS) of the extended generalized data envelopment analysis (EGDEA) model are investigated. The proposed EGDEA model is used to evaluate decision’s making units (DMUs) either with full convexity assumption imposed on inpu...

26 Enterobacteria like Escherichia coli generate formate, lactate, acetate and succinate as major 27 acidic fermentation products. Accumulation of these products in the cytoplasm would lead to 28 uncoupling of the membrane potential and therefore they must be either metabolized rapidly 29 or exported from the cell. E. coli has three membrane-localized formate dehydrogenases 30 (FDH) that oxidiz...

This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in a general inputs-outputs space, where inputs can include variance and kurtosis and outputs can include mean and skewness. Our work is in the vein of Briec, Kerstens and Jokung (2007) and Jurzenko, Maillet and Merlin (2006) who develop a directional distance (shortage function) appro...

Oxalic acid is a prevalent fungal metabolite with versatile roles in growth and nutrition, including degradation of plant biomass. However, the toxicity of oxalic acid makes regulation of its intra- and extracellular concentration crucial. To increase the knowledge of fungal oxalate metabolism, a transcriptional level study on oxalate-catabolising genes was performed with an effective lignin-de...

BACKGROUND As a natural fermentation product secreted by Clostridium species, bio-based 1-butanol has attracted great attention for its potential as alternative fuel and chemical feedstock. Feasibility of microbial 1-butanol production has also been demonstrated in various recombinant hosts. RESULTS In this work, we constructed a self-regulated 1-butanol production system in Escherichia coli ...

This work demonstrates the application of magnetic carbon-encapsulated iron nanoparticles (CEINs) for construction bioelectrodes in a biobattery and biofuel cell. It has been shown that are suitable material immobilization laccase (Lc) 1,4-naphthoquinone (NQ) fructose dehydrogenase (FDH). The system is stable; no leaching enzyme mediator from surface modified electrode was observed. onset catal...

We investigate several previously suggested scenarios of instantiating random oracles (ROs) with “realizable” primitives in cryptographic schemes. As candidates for such “instantiating” primitives we pick perfectly one-way hash functions (POWHFs) and verifiable pseudorandom functions (VPRFs). Our analysis focuses on the most practical encryption schemes such as OAEP and its variant PSS-E and th...

Forty-one volunteers (male non-smokers) were exposed to formaldehyde (FA) vapours for 4 h/day over a period of five working days under strictly controlled conditions. For each exposure day, different exposure concentrations were used in a random order ranging from 0 up to 0.7 p.p.m. At concentrations of 0.3 and 0.4 p.p.m., four peaks of 0.6 or 0.8 p.p.m. for 15 min each were applied. During exp...

We examine the lived experiences of foreign domestic helpers (FDH) working with community-dwelling older people in Hong Kong. Unstructured interviews were conducted with 11 female FDHs, and thematically analyzed. The theme inescapable functioning commodity represented the embodied commodification of FDHs to be functional for older people in home care. Another theme, destined reciprocity of comp...

This article reports the cloning of the genes encoding the Arabidopsis and rice class III ADH enzymes, members of the alcohol dehydrogenase or medium chain reductase/dehydrogenase superfamily of proteins with glutathione-dependent formaldehyde dehydrogenase activity (GSH-FDH). Both genes contain eight introns in exactly the same positions, and these positions are conserved in plant ethanol-acti...
