a computational fluid dynamic (cfd) study of methanol (meoh) to dimethyl ether (dme) process in an adiabatic fixed-bed reactor is presented. one of the methods of industrial dme production is the catalytic dehydration of meoh. kinetic model was derived based on bercic rate. the parameters of this equation for a specific catalyst were tuned by solving a one-dimensional homogenous model using mat...

We demonstrate a new cooling method in which a time-varying magnetic field gradient is applied to an ultracold spin mixture. This enables preparation of isolated spin distributions at positive and negative effective spin temperatures of ±50   pK. The spin system can also be used to cool other degrees of freedom, and we have used this coupling to cool an apparently equilibrated Mott insulator of...

We report on analytical and numerical results for the time evolution of a ~lattice! model of ferromagnetic particles after field inversion. Relaxation from the metastable phase occurs by superposition of two independent spin-flip processes: with probability 12p , the flip obeys the Metropolis rule at finite temperature, T , while the flip is performed at random, as for T→` , with probability p ...

(By measurement we mean all variables of a theoretical relation that determine the length have been quantitatively observed, no ROMs.) The skew above the electron skin depth of the scale length population determined an average scale length of the ‘‘EDRs’’ 80% higher than the upper bound stated in the ‘‘EDR’’ study’s abstract. This situation contributes another average multiplicative enhancement...

The criticality-enhanced magnetocaloric effect (MCE) near a field-induced quantum critical point (QCP) in the spin systems constitutes very promising and highly tunable alternative to conventional adiabatic demagnetization refrigeration. Strong fluctuations low-$T$ regime can give rise large thermal entropy change thus significant cooling when approaching QCP. In this work, through efficient ac...

In this talk I summarize the topics addressed during the conference. We have discussed the most relevant cosmological observations of the last say 10 years and their implications for our understanding of the Universe. My finding throughout this meeting has been that it is amazing how our knowledge of cosmological parameters has improved during the last years. It comes as a surprise to many, tha...
