Hydrothermal carbonization (HTC) technology was used to carbonize and improve biomass raw material obtain hydrochar. The effects of HTC temperature holding time on the yield, composition, structure, combustion behavior, safety hydrochar were studied systematically. In addition, results show that with increase in prolongation time, yield gradually reduces, fixed carbon content increases, volatil...

A horizontal travelling heater method (THM) for growing cylindrical crystals from a partially filled solution zone has been investigated for the first time. By applying ampoule rotation, the whole cross section of the crystal is successively brought into contact with the liquid solution, which is effectively stirred by forced convection. This approach was used to grow single-crystalline Hgt_xCd...

Hgl -,Cd,Te and Cdl -,Zn,Te single crystals were grown by the travelling heater method (THM), applying two different techniques of artificially stirring the solution zone. Accelerated crucible rotation (ACRT) was used in a vertical growth arrangement and compared a technique with constant rotation around the horizontal axis of the ampoule. The dominant hydrodynamic mechanisms of both methods ar...

Based on the deep in situ mining environments with ?three high?, a triaxial compression experiment of water-saturated sandstone under conditions 150?C, 110 MPa confining stress and 105 pore water was carried out. The results show that creep deformation stage produces surge acoustic emission energy when radial changes from expansion to rapid compression, is sheared by single crack it damaged. Fr...

Geologic disposal is a promising solution for safe permanent isolation of accumulated high-level nuclear waste from powerplants. The behavior host rock highly coupled thermally, hydromechanically, and chemically. Numerical simulations such phenomena the extremely long term (>100,000 years) large length scale (>1 km) geologic remain to be computationally challenging. In this study, methodology h...

A construct ive learning algori thm dynamical ly creates a problem-specific neural ne twork architecture rather t h a n learning o n a pre-specified architecture. W e propose a parallel vers ion of our recently presented construct ive neural ne twork learning algori thm. Parallelization provides a computat ional speedup by a fact o r of O ( t ) where t is t h e number of training ezamples. Dist...

In this paper, we first recall a previous favourable experience with the Schwarz type domain decomposition methods applied to problems of heat flow and elasticity [9, 11, 12] and then discuss a possible use of these methods for solving Darcy flow problems.

We prove that the model checking and the satisfiability problem of both Dynamic Logic of Propositional Assignments DL-PA and Coalition Logic of Propositional Control and Delegation DCL-PC are in PSPACE. We explain why the proof of EXPTIME-hardness of the model checking problem of DL-PA presented in [1, Thm 4] is false. We also explain why the proof of membership in PSPACE of the model checking ...

We report the formation of trihalomethanes and other disinfection by-products from four polyfunctional terpenoids during simulated chlorination of natural waters. Complex suites of products were identified by closed loop stripping analysis (CLSA)/gas chromatography-mass spectrometry (GC-MS) from halogenation of beta-carotene and retinol. beta-Ionone appeared to be a key intermediate in the halo...

Background: Heat cured acrylic resin is the most widely used material in the manufacture ofdenture base, but has mechanical properties weakness (transversal strength and impact strength). Alternative to increase the mechanical properties of acrylic resin is the utilization of reinforcing fibre that is polyethylene fibre that has advantage such as good aesthetic, easy to manipulate and increase ...
