Conversion of fructose to glucose by intestine of guinea pigs involves chain fragmentation in what appears to be an obligatory step, while glucose does not share a similar fate during active transport.A new method for degrading glucose,...

Recent studies of the growth rate of the different faces of potash alum crystals have revealed that these grow with variable growth rates. This phenomena can be considered on two time scales. In the long term “constant” growth remai...

By coupling to cholesterol, Hedgehog can be anchored to the cells where it is made, yet to act as a morphogen, it must be able to move away from its source. Novel genes have now been identified that control the release and dispersal of ...

Necessary and sufficient conditions for the existence of a common solution to the Lyapunov equation for two stable complex matrices are derived. These conditions are applied to the cases when a common weak solution to the Lyapunov equat...

Coccolithoviruses infect the marine coccolithophorid microalga Emiliania huxleyi. Here, we describe the genomes of four new coccolithoviruses isolated from UK coastal locations. Of particular interest, EhV-18 and EhV-145 encode serine p...

The use of a silicon photodiode array as a multi-wavelength detector which allows the recording of complete UV spectra for each component in the effluent from liquid chromatography is described. This detector gives noise levels of the o...

In this study the two main paradigms for looking at the design activity are compared in terms of their ability to describe the industrtial design process. Special interest is paid to how close these descriptions are to capturing the des...

Let K(t, b, R) denote the minimum cardinality of any mixed code which has t ternary and b binary coordinates and covering radius R. We collect upper bounds for K(t, b, R) when R ⩽3 and t+b⩽13 and discuss some simple methods to const...

Research library catalogs serve as authoritative sources of access. The increasing practice of including Web sites in the catalog, resources not under the library's control, raises new issues of the catalog's accuracy and reliability. A...

We present a model of exciton absorption and emission Nike Air Yeezy line shapes which predicts, inter alia, a linear relation between the absorption line width, Γ, and the Stokes shift, Δ, between the photoluminescence and the absorp...
