The choice of foaming agent and its mass fraction significantly affect the size number metal foam cells. powder metallurgy process was used to produce aluminium foams with addition various agents: titanium hydride (TiH2) calcium carbonate (CaCO3). TiH2 added in an amount 0.4 wt.%, while quantity CaCO3 varied between 3 5 wt.%. produced foams, approximately same degree porosity, were scanned usin...

We give a new proof of a theorem by Le Gall & Paulin, showing that scaling limits of random planar quadrangulations are homeomorphic to the 2-sphere. The main geometric tool is a reinforcement of the notion of Gromov-Hausdorff convergence, called 1-regular convergence, that preserves topological properties of metric surfaces.

Drying is a common process step for agricultural grain products ease of handling and to achieve the desired quality levels. One commodities that have high economic value produced by farmers in Lampung Province cocoa beans. The drying may change physical properties beans affect processing at later stage. This study aims determine effect temperature on changes such as dimension, volume, weight, s...

We present the formula for angular distribution of integral flux of conventional (π, K) muons deep under water taking into account the sphericity of the atmosphere and fluctuations of muon energy losses. The accuracy of this formula for various sea level muon spectra is discussed. The possibility of reconstructing two parameters of sea level spectrum by fitting measured underwater angular inten...
