The 105aa lambda S protein is the prototype holin, S accumulates in the cytoplasmic membrane during late gene expression until, at a time programmed into its primary structure, it disrupts the membrane and allows the lambda ...

The water-soluble phosphine complex of ruthenium(II), RuCl2(PTA)4, has been prepared by the reduction of RuCl3 in ethanol in the presence of the air-stable phosphine 1,3,5-triaza-7-phosphaadamantane. RuCl2(PTA)4 is an ...

Here we report two methods to synthesize hyperbranched poly(acrylic acid) grafts on polyethylene films and powders. The previously reported route using α,[]-diaminopoly(tert-butyl acrylate) was repeated and all previous ...

The transport of a conservative tracer (lithium) in a large (3.5 m3) undisturbed municipal solid waste sample has been investigated under steady and fully transient conditions using a simple model. The model comprises a ...

Solution methods for a system of nonlinear equations containing a convolution term are investigated in both frequency and time domains. Frequency domain analysis formulas are developed by using both the harmonic balance m ...
