Processing the experimental tie-lines in the miscibility gap of the Ba-Cu-Y ternary liquid alloys coupled with the Gibbs energies of the Ba-Cu and Cu-Y binaries estimated earlier has led to description of the Gibbs energy of the ternary melt and to the complete ternary phase diagram. The transformation of an open triangular simplex to the plane that can ease significantly optimization and calcu...

In this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in ESR processing has been investigated.The chemical composition and microstructure studies were evaluated, using spectrophotometer,OMand EDX analyses attached to SEM.The results show that ESR process has successfully reduced the amount and size of inclusions. In some c...

Coeval silicate melt and aqueous synthetic fluid inclusions were INTRODUCTION formed at 800°C and 2000 bars in the quartz-saturated haploIn recent years the study of silicate melt inclusions has granite–H2O–NaCl–KCl system. The equilibrium assemblage congained considerable popularity as a method to charsisted of Ab19·2Or31·1Qtz49·1 melt, quartz, and an aqueous solution acterize the PTX evolutio...

The paper presents two experimental methods for basalt processing by microwaves, and their results. One method employs a single-mode cavity to melt basalt, and to produce a volcanic glass (obsidian). The other method uses an open-end applicator (i.e. a microwave drill [1]) to form holes in basalt rocks. Experimental observations of the basalt interactions with microwaves in these two schemes ar...

In a document analysis system the skew error detection is one of the most crucial parts. This paper describes a method that takes advantage of texture orientation analysis in order to find the skew error from the source document. The source image is first shrunk to melt the characters in together, reduce noise and decrease the amount of computing. After pre-processing a texture direction analys...

Submarine melt can account for substantial mass loss at tidewater glacier termini. However, the processes controlling submarine melt are poorly understood due to limited observations of submarine termini. Here at a tidewater glacier in central West Greenland, we identify subglacial discharge outlets and infer submarine melt across the terminus using direct observations of the submarine terminus...

The permeability of the upper mantle controls melt segregation beneath spreading centers. Reconciling contradictory geochemical and geophysical observations at ocean ridges requires a better understanding of transport properties in partially molten rocks. Using x-ray synchrotron microtomography, we obtained three-dimensional data on melt distribution for mantle peridotite with various melt frac...

the melt-phase synthesis of dioctyltin (iv) and triphenyltin (iv) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (iv) compounds.the reagents were ground together in a mortar and fed into a boiling glass tube. a cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. a syringe ensureda continuous flow of d...

[1] The extent and thickness of the Arctic sea ice cover has decreased dramatically in the past few decades with minima in sea ice extent in September 2005 and 2007. These minima have not been predicted in the IPCC AR4 report, suggesting that the sea ice component of climate models should more realistically represent the processes controlling the sea ice mass balance. One of the processes poorl...

In this paper we report on some surprising, and we believe new, findings regarding the factors affecting the optical properties (haze) of polyethylene (PE) blown and cast films. A comprehensive investigation of blown and cast films made from conventional Ziegler-Natta catalyzed linear low density PE (LLDPE) as well as metallocene-catalyzed LLDPE (mLLDPE) resins was conducted. The large majority...
