    Notes: Summary. Ultrasound brain scans were obtained daily for the first 5 days after birth, on day 7 and then weekly until discharge from hospital in 86 babies during a 12-month period. The babies weighed 〈1501 g or were 〈34 weeks gestational age. Fifty-one (59%) had normal scans. 34 (40%) developed periventricular haemorrhage, and seven (8%) developed periventricular cysts (associated with periventricular haemorrhage in six). Factors associated with periventricular haemorrhage were perinatal hypoxia, acidosis, hypercapnia and hypoxia after birth. Babies who developed periventricular cysts (periventricular leukomalacia) were more likely to have been hypoxic at birth and in four of the seven there had been a maternal antepartum haemorrhage. The association of perinatal hypoxia with periventricular haemorrhage and leukomalacia suggests that intraparturm events may predispose to the onset of these lesions which then develop postnatally. Prevention of perinatal hypoxia may play an important role in diminishing the disability caused by these conditions.

    Notes: This paper looks at a number of others which bear on the interface between Corporate Strategy and R&D Planning to see if a more systematic approach can suggest a sequence to be followed so that Corporate Strategy can be seen as a source of ideas for R&D.The purpose of R&D is defined in terms of contributing to the competitiveness of the Company or Business Unit being served. The areas of competition or threats from the external environment are then explored using a model taken from Porter's book ‘Competitive Strategy’. Each area of competition is considered in turn and strategies identified which might enable the company to maintain its competitive edge. Sub-objectives for the R&D function can then be determined allocating resources and time for their completion.It is the performance of the R&D function inj fulfilling these sub-objectives which can be the basis of measuring the effectiveness of R&D.

    Notes: When corporate planning has been tried by a number of organizations a number of difficulties have arisen. These are often a consequence of the planning system itself and the manner of its introduction to the organization. A new approach is described in this paper by which planning is introduced in stages. Each is a logical development of the previous one but each makes a reasonable demand on the staff and there is time to ensure that the data needed at each stage by the staff is available. Furthermore, the staff contribute to the development of the planning system which, at each stage in its evolution, is adapted to their needs. Having thus described the introduction and evolution of a planning system in an organization, a later paper will review how the technical function of a company can link into it.

    Notes: Summary The degree of aggregation of some commercial polyoxyethylene sorbitan fatty acid esters (Tweens) and sorbitan fatty acid esters (Spans) in cyclohexane, carbon tetrachloride and chloroform has been investigated by light-scattering, vapour pressure osmometry and sedimentation velocity techniques. Light-scattering results were corrected for the contribution of fluorescence to the scattered light, which was appreciable at excitation wavelengths of 436 nm. Mean aggregation numbers of 26 and 12 monomers were determined for sorbitan monooleate (Span 80) in cyclohexane and carbon tetrachloride respectively. No significant aggregation of this compound was observed in chloroform. Other detergents studied showed only limited aggregation, if any, in these solvents. Correlation of the aggregation numbers of Span 80 with the solubility parameters, δ, of the solvents (including results from a previous investigation) indicated that the degree of aggregation approached a minimum value when the δ values of the solute and solvent were matched.

    Notes: Abstract Apnoeic oxygenation (AO) combined with extracorporeal CO2 removal (ECCO2R), using venovenous perfusion across a membrane area of 0.1m2 has been shown to be feasible in six healthy anaesthetized rabbits. In a further twelve rabbits, ECCO2R has been randomly compared with conventional mechanical ventilation (CMV) following saline lavage to induce respiratory failure. Blood gases were maintained for up to 6h within the same range (PaO2=8–20 kPa, PaCO2=4–6 kPa) in two groups of six by varying airway pressures and the oxygen fraction delivered either to the membrane lung (ECCO2R group) or to the ventilator (CMV group). The influence of single hourly sustained inflations (SI) on oxygenation was studied. ECCO2R subjects remained stable and survived. CMV subjects deteriorated and had 80% mortality. Hyaline membranes were absent from ECCO2R subjects and present in all CMV subjects. The response to SI suggests that a lung volume recruitment is maintained during AO for up to 1 h but is ineffective during CMV.

    Notes: Abstract A method has been devised which allows the rapid production of fine suspension cultures of small aggregate size from suspension cultures of large average aggregate size, such as those of Capsicum frutescens. The method, which uses a Waring blender for aseptic homogenisation of cultures, has also been shown to be effective in rapidly producing suspension cultures from callus cultures. The suspension cultures so produced are particularly useful for immobilisation, such as in porous polyurethane foam matrices.
