Weizhou island, located in the north margin of South China Sea (SCS), is characterized by multi-stage volcanism, several eruption styles and craters, also youngest Quaternary volcanic island China. An on this may pose high risk to life property. However, eruptive history craters number location, their sequence characteristics are still being debated, which important for potential hazard assessm...

1. Crystalline hexokinase has been isolated from baker's yeast. 2. Crystalline hexokinase is a protein of albumin type of a molecular weight of 96,000. Its isoelectric point is at about pH 4.8. 3. The method of isolation consists in separating the proteins of an aqueous extract of toluene-treated yeast by means of fractional precipitation with ammonium sulfate and with alcohol. 4. The procedure...

Development of computational modeling tools has revolutionized studies magmatic processes over the last four decades. Their refinement from binary mixing equations to thermodynamically controlled geochemical assimilation models provided more comprehensive and detailed constraints an array systems. One questions that not yet been vigorously studied using thermodynamic is origin massif-type anort...

‎it is commonly accepted that fractional differential equations play‎ ‎an important role in the explanation of many physical phenomena‎. ‎for‎ ‎this reason we need a reliable and efficient technique for the‎ ‎solution of fractional differential equations‎. ‎this paper deals with‎ ‎the numerical solution of a class of fractional differential‎ ‎equation‎. ‎the fractional derivatives are described...
