Etiology of aberrant social behavior consistently points to a strong polygenetic component involved in fundamental developmental pathways, with the potential of being enhanced by defects in bioenergetics. To this end, the occurrence of social deficits and mitochondrial outcomes were evaluated in conditional Pten (Phosphatase and tensin homolog) haplo-insufficient mice, in which only one allele ...

Nuclear safety has always been at the heart of concerns nuclear power plant operators and developers, as well various research organizations regulatory authorities. Over last decades, all these actors have developed integrated a large number calculation codes other tools into their work. From system approach to local understanding phenomenon on given component, from neutronics operation optimiz...

The supercritical carbon dioxide (sCO2) Brayton cycle is the preferred power for future nuclear energy, fossil solar and other energy systems. As regenerator in cycle, printed circuit heat exchanger (PCHE) exhibits a high transfer efficiency, compactness, robustness. structure design of its internal flow channel one most important factors to enhance reduce pressure loss. In present work, trapez...

The control of the main cycle parameters in supercritical CO2 (sCO2) systems during off-design and transient operation is crucial for advancing their technological readiness level. In smaller scale power units (<0.5–5 MW), costs complexity constraints limit number auxiliary components loop, making design system even more challenging. Among possible strategies, regulation inventory, which consis...

The design and techno-economic performance of a compact additively manufactured (AM) molten salt (MS)-to-supercritical carbon di-oxide (sCO2) primary heat exchanger (PHE) for solar thermal application is described. PHE consists sCO2 flow through an array microscale pin fins while the MS flows mm-scale rectangular channels. Constraints imposed by AM using laser powder bed fusion method are consi...

Abstract In the near future, due to growing share of variable renewable energy in electricity mix and lack large-scale storage, coal plants will have shift their role from base-load operation providing fluctuating back-up power. However, current power plants, based on steam Rankine cycle, are not optimized for flexible part-load operation, resulting an intrinsic inadequacy fast load variations....

Direct fired supercritical CO2 (sCO2) power cycles allow for the combustion of gaseous fuels under oxyfuel conditions with inherent carbon capture. As is captured intrinsically, efficiency penalty capture on overall plant small, meaning that plants achieve a similar to traditional fossil fuel without and storage. However, at high pressures in large dilutions CO2, mechanisms are poorly understoo...
