Rules of thumb (RoTs) are proposed as a means of promoting higher levels of Defined Contribution (DC) pension saving and to help stimulate debate about the high and uncertain cost of pension provision, leading to the development of solutions. The Lif

A Monte Carlo simulation of electron transport in a GaAs/AlAs superlattice is presented. The simulation is based on realistic superlattice band structure which is calculated by a method which matches complex empirical pseudopotential bulk band struct

Summary Certain organisms nucleate the crystallization of ice. This requires a small volume of water to be induced, probably by lattice-matching with a solid template, to form an‘ice embryo’—a region sharing at least some of the characteristics

Using synthetic DNA, we assembled a gene encoding a protein identical in sequence to one of the antifreeze proteins produced by the fish Pseudopleuronectes americanus (winter flounder). To address the relationship between structure and function, we a

Summary The kinetics of ice-nucleus assembly from newly synthesized nucleation protein were observed following induction of nucleation gene expression in the heterologous host Escherichia coli. Assembly was significantly slower for the small proporti

Some viable palindromic DNA sequences were found to cause an increase in the recovery of genetic recombinants. Although these palindromes contained no Chi sites, their presence in cis caused apparent recA+-dependent recombination to increase severalf

Antibiotic biosynthesis is regulated by glucose in Pseudomonas fluorescens HV37a. Fusions between antibiotic biosynthetic operons (afu operons) and the Escherichia coli lac operon were isolated to evaluate the genetic determinants for the regulation

The authors consider a GaAs/GaAlAs superlattice with a small electric field applied perpendicular to the layer planes. The electronic structure is examined in the envelope function approximation and the resulting miniband structure is used in a Boltz

The protein product of a gene (inaZ) responsible for ice nucleation by Pseudomonas syringae S203 has been identified and purified after overexpression in Escherichia coli. The amino acid composition and the N-terminal sequence of the purified, denatu

The estimation of total pyrethrins either by the A.O.A.C.* method of analysis or the Seil method yields high results in the presence of the synergist piperonyl butoxide, or DDT. Both these compounds, on hydrolysis with alcoholic potassium hydroxide,
