Migration, Environment and Climate Change
Human and hominin migrations have occurred since time immemorial. Settlement, the obverse of migration, requires a suitable climate, available food, lack of mortal threat from disease, societal calm and local ...

A new murine model of giant proximal axonopathy
The aromatic γ-diketone 1,2-diacetylbenzene (1,2-DAB), the putative active metabolite of the organic solvent 1,2-diethylbenzene, forms blue-colored polymeric protein adducts and induces the formation of amyotr...

British Carboniferous fossil reptile sites
Within the past decade two possible Carboniferous reptiles have come to light in Britain, one from the Lower Carboniferous of West Lothian, Scotland and the other from the Upper Carboniferous of Newsham, North...

Chapter
Introduction
Britain is famous for its fossil reptiles, partly for historical reasons, but also because there are so many richly fossiliferous localities that have supplied, and continue to supply, excellent material. The ...

Chapter
British Triassic fossil reptile sites
The British Triassic deposits have a broad Ushaped outcrop in the English Midlands, with a continuation south-westwards to south Wales and Devon (Figure 4.1). Smaller outcrops occur in northwest England, in No...

Chapter
British Mid Jurassic fossil reptile sites
Fossil reptiles have been found in numerous localities in the Mid Jurassic (Aalenian-Callovian) of southern England and west Scotland, but the most productive sources for reptiles are mainly in rocks of Bathon...

Chapter
British Cretaceous fossil reptile sites
The Cretaceous System in Britain (Figures 8.1, 8.2) is represented by two broad phases of deposition which relate to palaeogeography. Earth movements during the Late Jurassic uplifted most of north-west Europe...

Chapter
British Permian fossil reptile sites
British Permian time can be grouped into two broad units, an earlier phase of predominantly terrestrial deposition and a later phase characterized by greater marine influence. The Early Permian of the British ...

Chapter
British Early Jurassic fossil reptile sites
In Britain, rocks of Jurassic age occur in England in a long, almost continuous outcrop, running from Dorset to Yorkshire, also in South Wales and in scattered patches in the islands off north-west Scotland, a...

Chapter
British Late Jurassic fossil reptile sites
Late Jurassic reptiles have come from many localities along the length of the English outcrop, between the Dorset coast and Yorkshire, and are represented in rocks ranging in age from Late Oxfordian to the Por...

Chapter
British Caenozoic fossil reptile sites
The British Caenozoic is marked by extensive vulcanism in northern areas (especially Mull and the other Hebridean islands, and Northern Ireland), and by deposition of sediments in a number of basins in the Nor...

Dynamic Response of Semiconductor Nonlinear Optical Waveguides
Pump-probe excitation of passive nonlinear semiconductor optical wavegiudes is examined in the slowly varying envelope approximation. It is shown that the pump pulse may be used to control the chirp imposed on...

Introducing Dissipation in the Schrödinger Picture
We discuss various methods of introducing dissipation to the Schrodinger picture, in the light of the de Broglie-Bohm quantum potential viewpoint. This favours non-linear equations, and Kostin’s Schrödinger-La...

Adding dissipation to the Schrödinger equation from the quantum-potential viewpoint
We discuss methods of adding dissipation to the Schrödinger equation in light of the quantum-potential interpretation of quantum mechanics. This favors nonlinear equations in general and Kostin's Schrödinger-L...

Motor neuron degeneration linked to excitatory amino acids: Histological and immunocytochemical approaches
Excitatory amino acids are now associated with the pathophysiology of various neurological diseases such as brain ischemia and hypoglycemia, epilepsia [1–3] and some neurodegenerative disorders including Hunti...

Decrements in Retrograde Axonal Transport Precede Onset of Nerve Fiber Degeneration in Organophosphate Neuropathy
A single dose of some organophosphorous (OP) esters induces a central-peripheral distal axonopathy known as OP-induced delayed polyneuropathy, OPIDP (Johnson, 1982). Phosphinates, carbamates or sulphonates, su...

Events in degenerating cat peripheral nerve: Induction of Schwann cell S phase and its relation to nerve fibre degeneration
Severance of a peripheral nerve leads to a characteristic series of events in the distal stump, including the dissolution of axons and myelin and the proliferation of Schwann cells within their basal lamina. T...

Clioquinol and 2,5-hexanedione induce different types of distal axonopathy in the dog
The central distal axonopathy induced in dogs by the administration of high doses of clioquinol is contrasted with the central-peripheral distal axonopathy precipitated by intoxication with 2,5-hexanedione. Ma...
