    Notes: Abstract: A survey of patients with basal cell carcinomas (BCCs) revealed that major changes have occurred since the World War II. In the pre-World War II generations, men outnumber women and most BCCs occur on the head and neck. Men had more BCCs on the ear and trunk, while women had more on the head and leg. In the post-World War II generation, women outnumbered men and most BCCs occurred on the trunk.

    Notes: Abstract Growing urban transport congestion is a major cause of environmental problems, as well as delays. One may argue that this is a classic problem of externalities and can be readily corrected by means of the price mechanism. However, although interest is increasing in pricing as an element in any solution, the answer is not so easy. Despite the falling cost of microelectronics, urban road pricing remains complex, expensive to administer, and politically controversial. Nevertheless, modeling exercises and limited practical experience suggest that most, if not all, of these problems can now be overcome and that road pricing may now be successfully implemented. But the continued opposition to road pricing makes consideration of the alternatives necessary. Indeed, both for political and economic reasons, road pricing appears much more likely to be successfully implemented as part of a package of measures than in isolation.

    Notes: The infection of pea (Pisum sativum) by Colletotrichum truncatum was studied by light and electron microscopy. These investigations were facilitated by use of an Argenteum pea mutant, which has a readily detachable epidermis. Infection pegs emerging from appressoria penetrated epidermal cells directly. Large intracellular primary hyphae formed a dense stromatic mycelium confined within a single epidermal cell. Primary mycelia gave rise to thinner secondary hyphae which radiated into surrounding cells and caused extensive wall dissolution. Melanized sclerotia developed in the centre of chlorotic water-soaked lesions. Acervuli were not observed. Epidermal cells survived initial penetration by primary hyphae, as shown by their ability to plasmolyse and accumulate Neutral red, but all infected cells were dead when the secondary hyphae had formed. Six cultivars of pea were susceptible, but seven other legumes were resistant. A single isoform of polygalacturonase with a pI of 8·3 and apparent Mr of 40000 was purified from culture filtrates and the TV-terminal amino acid sequence determined. The relevance of the results to the taxonomy of C. truncatum and the relationships between infection process and host range are discussed.

    Notes: Abstract: Presumed skin cancers were excised from 46 consecutive outpatients without antibiotic cover. A purulent wound developed in ten patients. Similar, but contaminated lesions were excised from 40 patients, but mupirocin ointment was used before surgery. Not one purulent wound developed out of 45 excisions.

    Notes: A survey of people with skin cancer in tropical Australia detected a change in site of the prevalent cancer. In the post-war generation more basal cell carcinomas are occurring on the back and fewer on the head and neck. A reversal of the sex ratio was also detected, with more women being afflicted.

    Notes: A fungus with morphological features corresponding to the group species Colletorichum gloeosporioides was consistently isolated from cassava with shoots showing dieback symptoms in Ghana. When four locally-grown cultivars were inoculated with isolates of the fungus, they developed disease symptoms, which consisted of discrete dark brown lesions on the stems followed by defoliation. Koch's postulates were completed by re-isolating the fungus from the inoculated plants. The relatedness of the isolates lo other members of the genus Calletotrichum, whose identities were well established, was investigated by comparison of the nucleotide sequence of domain 2 of their ribosomal DNA. The cassava isolates differed from authentic isolates of C. gloeosporioides by only one nucleotide among the 193 analysed. The causal agent of cassava stem tip dieback (STDB) is thus identified as a form of C. gloeosporioides.

    Notes: Abstract The selection and evaluation of road schemes through the Leitch framework is based on a combination of cost-benefit analysis and environmental impact assessment. Both techniques involve the definition and valuation of a number of costs and benefits. These costs and benefits are defined and valued in isolation to each other so that we know virtually nothing about the relative valuation that people assign to different types of costs and benefits which might affect them directly or indirectly. This paper outlines the development of a method which allows people to conceptualise the costs and benefits of a road scheme in their own terms and then to rank schemes in relation to those costs and benefits. This method is based upon an interview process involving the use of repertory grid technique. The information from the repertory grid technique is used as a sound basis for determining trade-offs between attributes and for attempting to obtain monetary valuations of different project attributes. A number of exploratory interviews are reported which outline some of the difficulties with a number of the survey features including the choice of case-study, interviewer and information biases and sample and non-response biases. Various ways of dealing with these difficulties are discussed.

    Notes: Abstract Quaternionic quantum mechanics is investigated in the light of the great success of complex quantum mechanics. It is shown that to reproduce the results of complex quantum mechanics, quaternionic quantum mechanics must contain complex quantum mechanics.
