    Notizen: Near-field optical methods are used, together with the ability of an argon fluoride excimer laser to remove a wide variety of materials without the deposition of detectable heat, to produce structures with nanometer dimensionalities. In this new method of lithography, a hollow glass micropipette is used to guide the 193 nm light of the excimer laser to the surface to be ablated. With such micropipettes, patterns have been produced on photoresists with linewidths that are as small as 70 nm. By investigating the dimensionality of the structures drawn on the photoresist and on the substrate on which the photoresist was deposited, it appears that nonlinear characteristics of the ablation process may allow the near-field dimensionalities to be maintained at distances that are relatively remote from the tip of the pipette aperture.

    Notizen: The complex permittivity of various ceramics has been measured at elevated temperatures. The permittivity measurements were made using the cavity perturbation technique at a fixed frequency of 10.1 GHz. The temperature of the sample was varied from 800 to 1000 °C by independently heating the samples using a CO2 laser (up to 27 W) directed into the cavity. The samples were mounted in quartz micropipettes and illuminated through the quartz. The sample temperature was measured using an optical pyrometer. This method is valuable for measuring the microwave properties of solids that normally are exposed to microwave radiation at elevated temperatures such as high-power microwave sources, components, and windows.

    Notizen: A simple device has been built that will allow spectrophotometric measurements of very small samples (2–5 μl ) in capillary tubes. This attachment is sized to fit in the standard 12.5×12.5 mm2 sample holder slot of commercially available spectrophotometers. A cylindrical quartz lens focuses light from the source onto quartz (for UV measurements and visible measurements) micropipettes and a second lens recollimates the light before it is sent to the detector to optimize the light efficiency. This device was initially used to measure the concentration of small samples of concentrated pUC 8 DNA which has an absorption line at 260 nm.

    Notizen: In this study the potential performance benefits of easy goals were examined within the multiple cue probability learning paradigm (MCPLP). Specifically, the effects of varying levels of goal difficulty on performance and risk propensity (used to define a form of commitment) were investigated. With few exceptions, previous studies demonstrated support for difficult goals. In this study, contrary to the majority of past evidence, as goals became easier decision quality significantly improved. Moreover, risk propensity increased with easier goals and, as suggested by a post-hoc analysis, had more direct impact on decision makers’ behaviors than goal levels. Goal-related behavior in complex MCPLP tasks appears to significantly differ from the majority of goal evidence in other types of research due to the tendency for subjects to view complex task properties in the same context as goal levels.

    Notizen: Abstract: A survey of patients with skin cancer in southern Australia detected that the development of multiple BCCs is common. The incidence of multiple BCCs peaks during the sixth decade and reaches a plateau. Human leukocyte antigen (HLA) DR1 was associated with the development of multiple BCCs in people under the age of 55, but not in older people.

    Notizen: Abstract The impact of prematurity on the responsiveness of mothers and their 4-nionih-old infants was examined across three channels of communication: attentional, vocal and affective. Loglinear models were used to determine how the behavior of one partner was conditional upon the behavior of the other during home observations of '24 preterm and 24 term infants and their mothers. Visual attention was elicited by vocalization, and the onset of infant gaze was marled by a maternal smile. Mothers and infants responded to vocalizations with vocalizations, and mothers responded to smiles with smiles. Mothers of preterm infants were particularly responsive to their infants' signals within the: attentional. vocal and affective channels. Preterm infants demonstrated correspondingly heightened responsiveness within the vocal and affective channels.

    Notizen: Unexpectedly high blood oxygen tension in intensive care patients occurring over a 5-year period were found to have been caused by an apparently normally functioning ventilator which was intermittently acting as a conduit between the oxygen and air pipelines. Responses to a circular letter sent to Quality Control Pharmacists in England and Wales suggest that similar faults may have occurred at least five times in the past 10 years. Recommendations are given for the prevention of this problem, including monitoring of gas pipeline composition.

    Notizen: The path of those who would approach the study of Bentham's writings on Evidence has been considerably smoothed by the recent publication of William Twining's work on the evidence theories of Bentham and Wigmore. The material on evidence is now being tackled by the Bentham Project. It presents no easy task. The central core, The Rationale of Judicial Evidence, edited and published by John Stuart Mill in 1827, exists only in the printed version, the MSS from which Mill worked having disappeared. But a substantial body of related material which survives has yet to be thoroughly investigated, though William Twining has made a gallant start. A new edition of the work hitherto known as ‘An Introductory View of the Rationale of Evidence’, first printed in full in the Bowring edition of the Works of Jeremy Bentham is in preparation. The first fruits of this endeavour is that the title of that work as it should appear in due course in the new Collected Works will be Introduction to the Rationale of Evidence: An Introductory View for the Use of Lawyers as well as Non-lawyers, the title in fact given to the work by Bentham. It is intended that what follows should similarly be of use to non-lawyers as well as lawyers.
