I point out that all the arguments available in the literature against an astrophysical solution of the solar neutrino problem(s) do not exclude a yet not recognised class of solar models, in which an explosive energy source is present in the solar core besides the standard proton-proton and CNO cycle. It is shown from first principle physics that stars have a non-equilibrium energy source as w...

While U.S. slave institutions formally guaranteed slaveowner property, the threat of fugitive slaves constrained economic development in the slave sector. We present new evidence on the economics of the slave South, focusing on the enforcement of slave property rights. We collect data on the characteristics of, and money rewards offered to slave catchers for, individual runaway slaves from 20,0...

PURPOSE To describe and explain variations in first mental health service utilization before and after running away from home for homeless adolescents. METHODS Survey interviews were conducted with homeless and runaway youth in several Midwestern locations. The effects of family of origin factors and street experiences on the likelihood of seeing a mental health professional for the first tim...

Abstract Since the 2018 IAEA FEC Conference, FTU operations have been devoted to several experiments covering a large range of topics, from investigation behaviour liquid tin limiter runaway electrons mitigation and control stabilization tearing modes by electron cyclotron heating pellet injection. Other involved spectroscopy heavy metal ions, density peaking in helium doped plasmas, assisted s...

laguerre function has many advantages such as good approximation capability for different systems, low computational complexity and the facility of on-line parameter identification. therefore, it is widely adopted for complex industrial process control. in this work, laguerre function based adaptive model predictive control algorithm (ampc) was implemented to control continuous stirred tank rea...

-A pilot plant study on propane catalytic combustion in a membrane reactor with separate reactant feeds is presented. The membrane consisted of a porous alumina tube activated by insertion into its pores of a Pt/7-A1203 catalyst. The role of reactants concentration and of the feed flow rates were studied in the transport-controlled operating regime, where a number of interesting properties of t...
