    Notes: Abstract DNA-based molecular-marker techniques have been proven powerful in genetic diversity estimations. Among them, RFLP was the first and is still the most commonly used in the estimation of genetic diversity of eukaryotic species. The recently developed PCR-based multiple-loci marker techniques, which include RAPD, AFLP, Microsatellite-AFLP and inter-SSR PCR, are playing increasingly important roles in this type of research. Despite the wide application of these techniques, no direct comparison of these methods in the estimation of genetic diversity has been carried out. Here we report a direct comparison of DNA-based RFLP with various PCR-based techniques regarding their informativeness and applicability for genetic diversity analysis. Among ten pea genotypes studied, all the PCR-based methods were much more informative than cDNA-RFLP. Genetic diversity trees were derived from each marker technique, and compared using Mantel's test. By this criterion, all trees derived from the various molecular marker techniques, except for the tree derived from inter-SSR PCR, were significantly correlated, suggesting that these PCR-based techniques could replace RFLP in the estimation of genetic diversity. On the basis of this result, AFLP analysis was applied to assess the genetic diversity of a sample of accessions representing the various species and subspecies within the genus Pisum.

    Muscles within muscles: the neuromotor control of intra-muscular segments (1998)

    Notes: Abstract The aim of this investigation was to anatomically identify, and then determine the function of, individual segments within the human deltoid muscle. The anatomical structure of the deltoid was determined through dissection and/or observation of the shoulder girdles of 11 male cadavers (aged 65–84 years). These results indicate that the deltoid consists of seven anatomical segments (D1–D7) based upon the distinctive arrangement of each segment's origin and insertion. Radiographic analysis of a cadaveric shoulder joint suggested that only the postero-medial segment D7 has a line of action directed below the shoulder joint's axis of rotation. The functional role of each individual segment was then determined utilising an electromyographic (EMG) technique. Seven miniature (1 mm active plate; 7 mm interelectrode distance) bipolar surface electrodes were positioned over the proximal portion of each segment's muscle belly in 18 male and female subjects (18–30 years). EMG waveforms were then recorded during the production of rapid isometric shoulder abduction and adduction force impulses with the shoulder joint in 40 degrees of abduction in the plane of the scapula. Each subject randomly performed 15 abduction and 15 adduction isometric force impulses following a short familiarisation period. All subjects received visual feed back on the duration and amplitude of each isometric force impulse produced via a visual force-time display which compared subject performance to a criterion force-time curve. Movement time was 400 ms (time-to-peak isometric force) at an intensity level of 50% maximal voluntary contraction. Temporal and intensity analyses of the EMG waveforms, as well as temporal analysis of the isometric force impulses, revealed the neuromotor control strategies utilised by the CNS to control the activity of each muscle segment. The results showed that segmental neuromotor control strategies differ across the breadth of the muscle and that individual segments of the deltoid can be identified as having either “prime mover”, “synergist”, “stabiliser” or “antagonist” functions; functional classifications normally associated with whole muscle function. Therefore, it was concluded that the CNS can “fine tune” the activity of at least six discrete segments within the human deltoid muscle to efficiently meet the demands of the imposed motor task.

    Fire-retardant performance of some surface coatings for naval ship interior applications (1995)

    Notes: The fire-retardant performances of various surface coatings for naval ship interior applications have been evaluated by a number of small-scale fire test methods. The coatings were eveluated as topcoats by cone calorimetry and limiting oxygen index methods and as primer/topcoat systems by radiat heating, direct flame impingement and reverse panel heating procedures. The coatings investigated were (1) a solvent-based epoxy polyester, (2) a solvent-based fireretardant alkyd,(3) a solvent-based chlorimated alkyd and (4) a water-based acrylic. In terms of the measured parameters, the chlorinated alkyd has superior fire properties while the epoxy polyserter, the fire-retardant alkyd and parameters, the chlorinated alkyd has superior fire properties while the epoxy polyester, the fire-retardant alkyd and the acrylic have significat disadvantages in relation to fire propagation. The relatively low amount of hydrogen chloride (∼ 0.3% - mass per initial mass) evolved by the chlorinated alkyd during cone calorimetric combustion and its outstanding fire-retardant properties have resulted in it being considered acceptable for naval ship interior applications.
