A palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. The ceramic support surface was modified by two TiO2-boehmite and one γ-alumina layers to avoid Pd penetration in support pores. Thin and defect-free Pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using Pd nanopa...

The intention of the study was to investigate effect physical conditions such as aeration rate (1, 3, 5 L/min) well chemical including sodium nitrite (NaNO2), urea (CH4N2O) and ammonium chloride (NH4Cl) on biomass productivity fucoxanthin concentration A. capitellata. optimum cultures were cultivated in f/2 medium using nitrate (NaNO3) at light intensity 100 µmol photons/ m2s with 2 L/min L bub...

In this study, the flow boiling heat transfer and pressure drop characteristics of refrigerant R134a in micro-channels were experimentally investigated. The tests performed circular horizontal with inner diameters 0.5 mm 1 a heating length 300 mm. mass velocities varied from 500 kg/m2s to 2500 kg/m2s, fluxes 15 kW/m2 147 kW/m2. coefficient (HTC) frictional (FPD) measured discussed detail. Accor...

Due to its low global warming potential (GWP) and good environmental properties, CF3I can be a suitable component of refrigerant mixtures in the field refrigeration air conditioning. In this work, local condensation heat transfer characteristics were experimentally investigated plate exchanger (PHE). The experiments carried out under conditions vapor qualities from 1.0 0.0, at saturation temper...

where ρ [ kg m3 ] is the mass density of the phase α; ε [1] is the volume fraction occupied by the phase α; q [ m s ] is Darcy’s velocity of the phase α; ω i [1] is the mass fraction of component i in the α phase; Ji [ kg m2s ] is the flux vector representing the diffusive flux of component i in the phase α; f i [ 1 s ] is the source of component i in the phase α; ei [ 1 s ] is the gain of mass...

CONTEXT Flow cytometric immunophenotyping is a useful ancillary tool in the diagnosis and subclassification of acute myeloid leukemias (AMLs). A recent study concluded that CD64 is sensitive and specific for distinguishing AMLs with a monocytic component (ie, AML M4 and AML M5) from other AML subtypes. However, in that study, the intensity of CD64 was not well defined and the number of non-M4/n...

The slow regression rate induced by the high pyrolysis difficulty has limited application and development of hydroxyl-terminated polybutadiene (HTPB)-based fuels in hybrid rocket propulsion. Nickel oxide (NiO) shows possibility increasing HTPB-based catalyzing process polymer matrix our previous investigation; hence, this paper studies NiO particles thermal decomposition combustion HTPB fuel gr...

Unification of the global vertical datum has been a key problem to be solved for geodesy over long period, and main challenge unifying system is determine geopotential value W0 geoid calculate offset between local W0. The can calculated using grid mean sea surface (GMSS) data model (GGM). In this study, GMSS was measured with adjustment methods 24 years merged multi-satellite altimetry data. Ha...
