hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

background: toxoplasma gondii , the obligate intracellular parasite is life threatening in aids patients. diagnosis of toxoplasmosis is based on serological methods especially increasing of igm and igg titers, but finding of parasite or its components (antigenemia) may be beneficial method in order to detection of acute toxoplasmosis in immunocompromised patients. methods: ninety-four serum sam...

The paper reflects on some of the premodern protection instruments against dangers, apprehended as protoforms insurance technology. Knowing that insufficiency these to cover daily risks incurred by individuals, created need devise new ways protect resources, we problematize role played maritime insurance, seeking capture (i) regulatory norms which they were subject, (ii) traits brought them clo...

This study carried out on the provided textures at laboratory. The provided textures were infusedinside the PVC cylinder with 30cm height and 25cm diameter. The studied textures were loamysand, sandy loam, sandy clay-loam, clay loam and clay. After 24 hours of saturation, the soil watercontent of the samples was measured by oven-dry gravimetric and TDR methods. For each texturesat any stage of ...

This paper presents an institutional model to investigate the cooperation between a government and central bank. The former selects monetary policy then delegates organization of macroprudential latter. Their stances are result sequential constrained utility maximization. Using indirect inference, we find set coefficients that can capture UK for 1993–2016. suggests post-crisis regulation has be...

One of the great challenges in the post-genomic era is to decipher the underlying principles governing the dynamics of biological responses. As modulating gene expression levels is among the key regulatory responses of an organism to changes in its environment, identifying biologically relevant transcriptional regulators and their putative regulatory interactions with target genes is an essenti...

Techniques of comparative genomics are being used to identify candidate functional DNA sequences, and objective evaluations are needed to assess their effectiveness. Different analytical methods score distinctive features of whole-genome alignments among human, mouse, and rat to predict functional regions. We evaluated three of these methods for their ability to identify the positions of known ...
