Direct measurements of NOx concentration and flux were made from a tall tower in central London, UK as part of the Clean Air for London (ClearfLo) project. Fast time resolution (10 Hz) NO and NO2 concentrations were measured and combined with fast vertical wind measurements to provide top-down flux estimates using the eddy covariance technique. Measured NOx fluxes were usually positive and rang...

1. Toluene (TOL) is widely used in industry. Occupational exposure to TOL is commonly assessed using TOL in blood, hippuric acid and ortho-cresol. Levels of these biomarkers may depend on factors potentially interfering with TOL biotransformation, such as the presence of other solvents in the workplace. Mercapturic acids (MAs) could be an alternative to the "traditional" TOL biomarkers. 2. This...

Cognitive slowing is a feature of problem solving performance by Parkinson’s patients. Here we present a computational model of the Tower of London problem solving task that provides a straightforward explanation of this latency impairment. The model is a neural network consisting of a set of idealized neurons whose activation levels are continuously varying quantities ranging between 0 and 1, ...

Since Hamilton’s Icosian Game, graphs have been used to represent mathematical puzzles. One of the most famous ones, the Tower of Hanoi (TH), is very popular in psychological tests. However, until quite recently the mathematical theory of the underlying graph structure for this and related puzzles like the Tower of London has not been fully exploited. We present the results of a project which a...

A series of colicin-tolerant (tol) mutants of Escherichia coli K-12, which adsorbed colicins but were not killed by them, were isolated and studied genetically and physiologically. Three major classes of mutants were found: tol II, tolerant to colicins A, E1, E2, E3, and K; tol III, tolerant to A, E2, E3, and K; and tol VIII, tolerant to E1 only. The sites of tol II and tol III mutations mapped...

A randomized, controlled study was carried out to assess the effect of a series of 10 sessions of high-frequency rTMS to the right DLPFC in 10 Borderline Personality Disorder patients. Patients in the rTMS group showed improvements in anger, affective instability (Borderline Personality Disorder Severity Index) and planning (Tower Of London). Two smoking cessations were observed.
