    Mapped topographic features are important for understanding processes that sculpt the Earth's surface. This paper presents maps that are the primary product of an exercise that brought together 27 researchers with an interest in landform mapping wherein the efficacy and causes of variation in mapping were tested using novel synthetic DEMs containing drumlins. The variation between interpreters (e.g. mapping philosophy, experience) and across the study region (e.g. woodland prevalence) opens these factors up to assessment. A priori known answers in the synthetics increase the number and strength of conclusions that may be drawn with respect to a traditional comparative study. Initial results suggest that overall detection rates are relatively low (34–40%), but reliability of mapping is higher (72–86%). The maps form a reference dataset

    Observations of a plastic crystalline phase in solid MBBA

    No full text
    Wideline and high resolution NMR studies have been carried out in MBBA in its isotropic, nematic and solid phases. Isotropic and nematic spectra correspond to what has been reported earlier. In the solid phase, contrary to expectations, very intense narrow signals similar to signals of the isotropic phase have been observed for the first time at temperatures close to the solid \leftrightarrow nematic phase transition temperature. This indicates rapid reorientational or translational motion in the system. X-ray results, owever, confirm the existence of translational order. The results are interpreted as indicative of the existence of a plastic crystalline phase in MBBA
